Depression is related to the normal emotions of sadness and
bereavement, but it does not remit when the external cause of
these emo-tions dissipates, and it is disproportionate to their
cause. Classic severe states
of depression often have no external precipitating cause. It is
difficult, however, to
draw clear distinctions between depressions with and those
without psychosocial
precipitating events.1 The diagnosis of major depressive
disorder requires a distinct
change of mood, characterized by sadness or irritability and
accompanied by at least
several psychophysiological changes, such as disturbances in
sleep, appetite, or sex-
ual desire; constipation; loss of the ability to experience
pleasure in work or with
friends; crying; suicidal thoughts; and slowing of speech and
action. These chang-
es must last a minimum of 2 weeks and interfere considerably
with work and fam-
ily relations. On the basis of this broad definition, the lifetime
incidence of depres-
sion in the United States is more than 12% in men and 20% in
women.2 Some have
advocated a much narrower definition of severe depression,
which they call melan-
cholia or vital depression.3
A small percentage of patients with major depression have had
or will have manic
episodes consisting of hyperactivity, euphoria, and an increase
in pleasure seeking.
Although some pathogenetic mechanisms in these cases and in
cases of major depres-
sive disorder overlap, a history of mania defines a distinct
illness termed bipolar dis-
order.4
Depression is a heterogeneous disorder with a highly variable
course, an inconsis-
tent response to treatment, and no established mechanism. This
review presents the
major current approaches to understanding the biologic
mechanisms of major de-
pression.
G e n e t i c s
Studies comparing concordance rates for major depression
between monozygotic and
dizygotic twins suggest a heritability of about 37%,5 which is
much lower than the
heritability of bipolar disorder or schizophrenia. Some aspects
of the normal person-
ality, such as avoidance of harm, anxiousness, and pessimism,
are also partly heritable.6
Kendler et al.7 showed that although depression is due in part to
heritable depression-
prone personality traits, it is also the result of heritable factors
that are independent
of personality. Early-onset, severe, and recurrent depression
may have a higher heri-
tability than other forms of depression.8 It is clear from studies
of families that major
depression is not caused by any single gene but is a disease with
complex genetic fea-
tures. Studies of pedigrees with multiple cases of major
depression have identified
chromosomal regions with linkage to the disorder, and some of
these loci have been
replicated in more than one study, although no single
chromosomal region has been
replicated in every family study of genetic linkage in
depression. Holmans et al.9 found

n engl j med 358;1 www.nejm.org january 3, 200856
evidence of linkage of recurrent, early-onset de-
pression to chromosome 15q25-q26, but the pop-
ulation attributable risk was small.
No specific molecular risk factor has been reli-
ably identified. One common polymorphic variant
of the serotonin-transporter–linked polymorphic
region (5-HTTLPR), which affects the promoter of
the serotonin-transporter gene, causes reduced
uptake of the neurotransmitter serotonin into the
presynaptic cells in the brain.10 Some studies have
shown that this polymorphism confers a predis-
position to depression,11 but it also confers a pre-
disposition to an anxious and pessimistic person-
ality.10 Brain imaging reveals functional differences
in emotion-related areas of the brain among car-
riers of the different common polymorphisms of
5-HTTLPR,12 although a direct relation to depres-
sion is unclear. In a large, prospective epidemio-
logic study, Caspi et al.13 found that 5-HTTLPR
predicted depression only in association with de-
fined life stresses. Some environmental factors
could confer a predisposition to depression by af-
fecting the genome epigenetically — for example,
increased maternal care in rodents causes an epi-
genetic change in the promoter region of the glu-
cocorticoid-receptor gene.14

The noradrenergic and serotonergic systems orig-
inate deep in the brain and fan out over almost
the entire brain, suggesting a system capable of
modulating many areas of feeling, thinking, and
behaving. The early antidepressants blocked the
reuptake of norepinephrine and serotonin by the
presynaptic neuron. The immediate effects of this
pharmacologic action are to increase the availabil-
ity of norepinephrine and serotonin in the synapse
and to increase stimulation of the postsynaptic
neuron. Inhibitors of the enzyme monoamine oxi-
dase were also discovered to have antidepressant
properties. This enzyme catabolizes norepineph-
rine and serotonin in their respective presynaptic
neurons, and such inhibition could be expected to
increase the availability of neurotransmitters. These
discoveries led to a major theory of depression
known as the monoamine-deficiency hypothesis.
Numerous studies of norepinephrine and serotonin
metabolites in plasma, urine, and cerebrospinal
fluid, as well as postmortem studies of the brains
of patients with depression, have yet to identify the
purported deficiency reliably. However, a newly dis-
covered form of the enzyme tryptophan hydroxy-
lase, designated TPH-2, is specific to the brain15
and could explain why previous postmortem stud-
ies of total enzyme activity did not show differ-
ences in tryptophan hydroxylase activity between
patients with depression and controls.16 A recent
positron-emission tomographic study using a li-
gand for brain monoamine oxidase showed a 30%
increase of the enzyme in a subgroup of patients
with depression.17 A study measuring differences
in monoamine metabolites between the internal
jugular vein and the brachial artery showed lower
production by the brain of norepinephrine metabo-
lites in patients with depression than in controls.18
The monoamine-deficiency hypothesis continues
to stimulate research whenever a new technical
window into the brain is opened.
Serotonin and norepinephrine can be depleted
experimentally in humans by oral treatments.19
A drink containing all amino acids except trypto-
phan stimulates the liver to synthesize proteins
and rapidly depletes the plasma (and therefore the
brain) of tryptophan. Tryptophan is rate-limiting
for serotonin synthesis in the brain. Such oral
tryptophan depletion does not induce depression
in healthy subjects but will cause a relapse of de-
pression in patients who have been successfully
treated with a serotonin-reuptake inhibitor.19 Sim-
ilarly, α-methyl paratyrosine inhibits tyrosine hy-
droxylase, the rate-limiting step in catecholamine
synthesis. Treatment with α-methyl paratyrosine
does not induce depression in normal subjects but
will induce a relapse in patients who have been
treated successfully with a norepinephrine-reup-
take inhibitor.19 These findings suggest that nor-
epinephrine and serotonin have critical roles in the
mechanisms of these treatments of depression but
that additional neurochemical factors are neces-
sary to cause depression.
Because direct measurements of monoamine
neurotransmission did not yield definitive findings
in relation to depression, the downstream effects
of monoamine neurotransmission were explored
(Fig. 1). The serotonin-1B receptor is located pre-
synaptically and regulates the release of serotonin
by feedback inhibition. Postmortem studies show
that the levels of p11, a protein that enhances the
efficiency of serotonin-1B receptor signaling, are
decreased in the brains of patients with depres-
sion.20 The serotonin-1A receptor is located both
presynaptically and postsynaptically to regulate
mech a nisms of dise a se
n engl j med 358;1 www.nejm.org january 3, 2008 57
serotonin function (Fig. 1). The receptor can be
evaluated in patients with depression by injecting
specific agonists and measuring specific neuro-
endocrine responses, such as elevation of the pro-
lactin level.21 Results suggest that the sensitivity
of this receptor is reduced in patients with depres-
sion.21 The α2-noradrenergic receptor, which is
usually presynaptic, modulates norepinephrine re-
lease by feedback inhibition (Fig. 1). Heightened
receptor sensitivity has been described in patients
with depression,22 which is consistent with re-
duced norepinephrine release.
It is conceivable that the second-messenger sys-
tems for serotonergic and noradrenergic neuro-
transmission malfunction in depression, and for
this reason the phosphatidylinositol and cyclic
AMP second-messenger systems have been exten-
sively evaluated. Reduced inositol levels have been
found in postmortem studies of the brains of per-
sons who have died by suicide23 and in magnetic
resonance spectroscopic studies of the frontal cor-
tex in patients with depression.24 A blunted cyclic
AMP response to stimulation was found in post-
mortem studies of the brains of patients with de-
pression.25 These reductions in second-messenger
function may impair neurotransmitter function
even without changes in monoamine levels or re-
ceptor numbers. These data indirectly support
elaborations of the original monoamine-deficiency
hypothesis of depression (Fig. 1).
G proteins that mediate signaling between re-
ceptors and second-messenger systems have also
been investigated in patients with depression, both
in postmortem studies of the brain26 and in stud-
ies of peripheral-blood cells.27 Although these
systems are clearly affected, no consistent picture
has emerged because there are numerous forms
of G proteins that vary in different areas of the
brain. The cyclic AMP response element–binding
protein (CREB) is a transcription factor affected by
cyclic AMP in the cell. In an animal model of de-
pression, rats with overexpression of CREB in the
dentate gyrus behaved similarly to rats treated
with antidepressants, but the opposite effect was
found when CREB was overexpressed in the nu-
cleus accumbens.26,28 Thus, the role of CREB in
depression is specific to the region of the brain.
Most but not all studies show that long-term treat-
ment with antidepressants stimulates CREB func-
tion, possibly depending on the type of drug and
the dosage.28 Levels of CREB and phospho-CREB
were reduced in postmortem studies of the cor-
texes of patients who had a major depressive
disorder and had not taken antidepressants, as
compared with controls.26,28 Many studies of sec-
ond-messenger systems and transcription factors
in depression were inspired by the belief that it
takes several weeks before antidepressant treat-
ment has an effect; consequently, the studies were
designed to detect time-dependent biochemical
changes in the cell. New meta-analyses suggest
that antidepressant effects begin rapidly, howev-
er,29 thereby supporting the classic monoamine-
deficiency hypothesis.
A strong point of the monoamine theory has
been its predictive power. Almost every compound
that has been synthesized for the purpose of in-
hibiting norepinephrine or serotonin reuptake has
been proved to be a clinically effective antidepres-
sant. A behavioral model of depression has been
developed in which a rodent is placed in a glass
cylinder filled with water, the sheer wall offering
no chance of escape. The animal struggles for a
while and then floats passively (the forced swim
test). A single prior injection of antidepressant in-
creases the struggling time; results in this model
have excellent predictive validity for new antide-
pressants. Other animal models have been devel-
oped by selective breeding of rats for depression-
like behavior, and these genetically susceptible
rodents also have a response to antidepressants.30
Still other models that can be studied biochemi-
cally induce depression with the use of long-term
mild stress or learned helplessness. However, no
animal model of depression captures the periodic
change of behavior into and out of depression that
is seen in patients with depression.
Molecular techniques such as gene knockout
partially support the monoamine theory of depres-
sion. The serotonin-reuptake–transporter knock-
out mouse is excessively anxious and characterized
by increased immobility in the forced swim test.31
This effect is similar to that of the low-activity
polymorphic variant of the serotonin receptor on
human personality10 but is the opposite of the ex-
pected effects of serotonin-reuptake–inhibitor an-
tidepressants. However, this inconsistency could
be explained by the difference between a chron-
ic monoamine abnormality during brain develop-
ment31 and the hypothesized acute monoamine
depletion in an adult with depression. Table 1
shows the effects in mice of knocking out genes
related to monoamine neurotransmitters.
The effects of stimulants on mood indirectly

support the monoamine-deficiency hypothesis of
depression and show that mood can be altered
rapidly. Cocaine and amphetamines are powerful
releasers of monoamines into the synapse as well
as inhibitors of reuptake. Their mood-elevating
effects are immediate, but in patients with severe
depression they have often been reported to cause
agitation rather than relief of depression. This
finding could reflect the ability of these stimulants
to deplete the presynapse of monoamines and thus
cause a “crash” into depression. Recent studies
support the theory that an acute response to a
single dose of amphetamine predicts a patient’s
longer-term response to monoamine-reuptake in-
hibitors.46
The role of dopamine deficiency in depression
is suggested by the frequency of depression in pa-
tients with Parkinson’s disease and the effect of
reserpine, which depletes serotonin, norepineph-
rine, and dopamine, causing a hypoactive state in
animals. The antidepressant agent buproprion in-
hibits the reuptake of dopamine. Some direct do-
pamine-receptor agonists, such as pramipexole,
have been reported to be efficacious in the treat-
ment of depression, even though they were devel-
oped for Parkinson’s disease.47
A major liability of the monoamine-deficiency
hypothesis is its derivation from the mechanism
of currently available antidepressants. Approxi-
mately two thirds of patients have a clinical re-
sponse to these agents, whereas one third have a
response to placebo.48 Perhaps the mechanism of
depression is not related to monoamines in two
of three cases.

Stress49 is perceived by the cortex of the brain and
transmitted to the hypothalamus, where cortico-
tropin-releasing hormone (CRH) is released onto
pituitary receptors. This stimulus results in the se-
cretion of corticotropin into plasma, stimulation
of corticotropin receptors in the adrenal cortex,
and release of cortisol into the blood. Hypothalam-
ic cortisol receptors respond by decreasing CRH
production to maintain homeostasis (Fig. 2).
There is considerable evidence that cortisol and
its central releasing factor, CRH, are involved in
depression.50,51 Patients with depression may have
elevated cortisol levels in plasma,38 elevated
CRH levels in cerebrospinal fluid,50 and increased
levels of CRH messenger RNA and protein in
limbic brain regions.50 In studies using dexa-
methasone to evaluate the sensitivity of the hypo-
thalamus to feedback signals for the shutdown of
CRH release, the normal cortisol-suppression re-
sponse is absent in about half of the most se-
Figure 1 (facing page). The Monoamine-Deficiency
Hypothesis Extended.
The monoamine hypothesis of depression postulates
a deficiency in serotonin or norepinephrine neurotrans-
mission in the brain. Monoaminergic neurotransmis-
sion is mediated by serotonin (5-hydroxytryptamine
1A [5-HT1A] and 5-hydroxytryptamine 1B [5-HT1B]) or
norepinephrine (noradrenaline) released from presyn-
aptic neurons (serotonergic neuron, shown on the left
side, and noradrenergic neuron, shown on the right
side [condensed virtually]). Serotonin is synthesized
from tryptophan, with the first step in the synthetic
pathway catalyzed by tryptophan hydroxylase; norepi-
nephrine is synthesized from tyrosine, with the first
step catalyzed by tyrosine hydroxylase. Both mono-
amine transmitters are stored in vesicles in the presyn-
aptic neuron and released into the synaptic cleft, there-
by affecting both presynaptic and postsynaptic
neurons. Cessation of the synaptic action of the neu-
rotransmitters occurs by means of both reuptake
through the specific serotonin and norepinephrine
transporters and feedback control of release through
the presynaptic 5-HT1A and 5-HT1B regulatory autore-
ceptors for serotonin and the α2-noradrenergic autore-
ceptors for norepinephrine. Monoamine oxidase A
(MAO-A) catabolizes monoamines presynaptically and
thereby indirectly regulates vesicular content. The pro-
tein p11, which interacts with 5-HT1B receptors, in-
creases their function. Postsynaptically, both serotonin
and norepinephrine bind two kinds of guanine nucleo-
tide triphosphate–binding protein (G protein)–coupled
receptors: cyclic AMP (cAMP)–coupled receptors,
which activate adenylate cyclase (AC) to generate
cAMP, and phosphatidylinositol (PI)–coupled recep-
tors, which activate phospholipase C (PLC). PLC gener-
ates inositol triphosphate (IP3) and diacylglycerol
(DAG); cAMP activates protein kinase A (PKA), and IP3
and DAG activate protein kinase C (PKC). The two pro-
tein kinases affect the cAMP response element–bind-
ing protein (CREB). Findings in patients with depres-
sion that support the monoamine-deficiency
hypothesis include a relapse of depression with inhibi-
tion of tyrosine hydroxylase or depletion of dietary
tryptophan, an increased frequency of a mutation af-
fecting the brain-specific form of tryptophan hydroxy-
lase (TPH-2), increased specific ligand binding to
MAO-A, subsensitive 5-HT1A receptors, malfunction-
ing 5-HT1B receptors, decreased levels of p11, poly-
morphisms of the serotonin-reuptake transporter asso-
ciated with depression, an inadequate response of G
proteins to neurotransmitter signals, and reduced lev-
els of cAMP, inositol, and CREB in postmortem brains.

verely depressed patients.52 Antidepressant-induced
clinical remission is accompanied by reversal of
some of these abnormalities.52
Adults with a history of physical or sexual
abuse as children have increased levels of CRH in
cerebrospinal fluid.53 Adult rodents that were sepa-
rated from their mothers or abused as pups show
increased immobility in the forced swim test,
which is reversed by antidepressant treatment.54
Mice with region-specific knockout of the gluco-
corticoid receptor at an adult age have increased
activity of the hypothalamic–pituitary–adrenal axis
and increased immobility in the forced swim test,
both of which are reversed by antidepressants.55
Increased levels of monoamines in the synapse
affect the hypothalamic–pituitary–adrenal axis56
and reverse some of the long-term effects of
stress.56 It is possible that antidepressants relieve
depression by reducing the secondary stress caused
by a painfully dispirited mood rather than by di-
rectly elevating mood. An antistress mechanism
could explain the general usefulness of antidepres-

sants for a wide variety of psychiatric conditions,
including panic disorder, post-traumatic stress
disorder, bulimia, premenstrual syndrome, and
obsessive–compulsive disorder. CRH-receptor an-
tagonists show antidepressant activity in animal
models,57 but the results of large clinical trials
have been disappointing. A compound that blocks
the glucocorticoid receptor has been reported to
be efficacious in depression, but only the most
severe and psychotic type.58
A single test for the cortisol level in blood does
not contribute to the diagnosis of depression, since
levels of cortisol vary markedly in a circadian
rhythm38 and because the overlap between values
in patients and those in controls is considerable.
Mild stress induced in the laboratory, such as
Figure 2. The Hypothalamic–Pituitary–Cortisol System in
Depression.
The hypothalamic–pituitary–cortisol hypothesis of depression
postulates that abnormalities in the cortisol response
to stress may underlie depression. The black arrows show that
in response to stress, which is perceived by the brain
cortex and the amygdala and transmitted to the hypothalamus,
corticotropin-releasing hormone (CRH) is released,
inducing the anterior pituitary gland to secrete corticotropin
into the bloodstream. Corticotropin stimulates the ad-
renal cortexes to secrete the glucocorticoid hormone cortisol.
The red lines show that cortisol, in turn, induces feed-
back inhibition in the hypothalamus and the pituitary,
suppressing the production of CRH and corticotropin, respec-
tively. Findings in patients with depression that support the
hypothalamic–pituitary–cortisol hypothesis include the
following: cortisol levels are sometimes increased in severe
depression, the size of the anterior pituitary and adrenal
cortex is increased, and CRH levels in the cerebrospinal fluid
and CRH expression in the limbic brain regions are in-
creased. Hippocampal size and the numbers of neurons and glia
are decreased, possibly reflecting reduced neuro-
genesis due to elevated cortisol levels or due to reduced brain-
derived neurotrophic factor.

stress associated with mental arithmetic calcula-
tions or simulated public speaking, results in
greater changes in plasma cortisol levels than
most reported differences between the values in
patients with depression and those in controls.38
It is possible that chronic mild elevations of cor-
tisol, especially at night, when cortisol levels in
normal subjects are very low, have a pathogenic
role in depression. It is also possible that periph-
eral cortisol elevations are only a ref lection of
central disturbances in CRH signaling, which me-
diate the effects of environmental stress on mood.59
A major liability of the hypothalamic–pituitary–
adrenal axis theory of depression is the difficulty
of defining the relationship of stress to depres-
sion. Some patients have a single lifetime depres-
sive episode, whereas a larger proportion have a
recurrent or even chronic course. Various types
of acute stress, early childhood trauma, or long-
term psychosocial problems may be involved and
may lead to different responses of the stress sys-
tem. Stress may be causative in some cases and
secondary to depressed mood in others.
Severe stress in rodents does not necessarily
model the common stresses of childhood. The
association of abuse in childhood with psycho-
pathologic disorders, including depression, in
adulthood could be due to common factors link-
ing family perpetrators of abuse and their victims,
including not only shared genes but also a shared
environment of poverty, poor nutrition, and poor
prenatal care. Depression is not uncommon in
people with no psychosocial risk factors. Most
patients treated for depression have no evidence
of hypothalamic–pituitary–adrenal dysfunction,
just as most such patients have no direct evidence
of brain monoamine deficiency.
The classic teaching is that neurons do not di-
vide in the adult mammalian brain, but studies
have shown that neurogenesis occurs in several
areas of the brain, especially the hippocampus.
Neurogenesis is more prominent in rodents than
in primates,60 and some have questioned whether
it occurs in the human cortex.61 Elevated levels of
glucocorticoids can reduce neurogenesis, and this
has been suggested as a mechanism for the de-
creased size of the hippocampus on magnetic
resonance images of the brain in many patients
with depression.62 In postmortem studies of pa-
tients with depression, cell loss in the subgenual
prefrontal cortex, atrophy in the dorsolateral pre-
frontal cortex and the orbitofrontal cortex, and T

increased numbers of cells in the hypothalamus
and the dorsal raphe nucleus have been reported.63
These effects resemble the atrophic changes in the
brain in patients with Cushing’s disease64 and in
rodents treated with glucocorticoids.65 However,
cortisol elevations in depression are much lower
than in Cushing’s disease.
Restraint in a small container induces stress in
rodents, suppressing neurogenesis, and this effect
is countered by antidepressant treatment.66 An-
tidepressants also enhance neurogenesis in non-
human primates.67 Santarelli et al.68 irradiated the
hippocampus in mice and abolished neurogene-
sis. They found that the radiation also abolished
the ability of the animals to respond behaviorally
to antidepressant treatment in the forced swim
test, but this phenomenon does not occur in every
mouse strain studied.69 Henn and Vollmayr sum-
marized other studies providing evidence that de-
creased neurogenesis is a result of stress and
anxiety but may not be behaviorally relevant.70 The
relevance of animal models of neurogenesis to
clinical studies of depression has been questioned
by analogy with studies of neuroprotection strat-
egies in stroke, for which numerous findings in
animal models have not been replicated in hu-
man studies.71
Brain-derived neurotrophic factor (BDNF),
a neurotrophic peptide, is critical for axonal
growth, neuronal survival, and synaptic plastic-
ity,72 and its levels are affected by stress73 and
cortisol.74 A postmortem study of patients with
depression who had committed suicide showed
that BDNF was reduced in the hippocampus.75
Antidepressant drugs and electroconvulsive thera-
py up-regulate BDNF and other neurotrophic and
growth factors75,76; a single bilateral infusion of
BDNF into the dentate gyrus has antidepressant-
like effects.77 One study showed that the hippo-
campus was smaller than normal in patients with
depression who carried a met166 BDNF allele.78
In an animal model of depression, epigenetic his-
tone methylation mediated down-regulation of
BDNF transcripts and antidepressant treatment
reversed this effect.79 These studies suggest that
BDNF is the link among stress, neurogenesis, and
hippocampal atrophy in depression. However,
a genetic association of the BDNF val166met poly-
morphism with depression has not been replicated
in most studies,74 and BDNF may be related not
only to depression but to multiple psychiatric dis-
orders.74 BDNF-knockout mice have behaviors un-
related to depression.45 Reduced BDNF levels in
the peripheral blood of patients with depression
seem to derive almost entirely from blood plate-
lets,80 and many artifacts must therefore be con-
sidered in interpreting these findings. Inflamma-
tion in the brain and some neurotoxins increase
brain BDNF levels, suggesting that the actions of
BDNF are not uniformly therapeutic.81 Castrén82
has proposed that antidepressant treatments may
increase synaptic sprouting and allow the brain
to use input from the environment more effec-
tively to recover from depression. This hypothe-
sis highlights the role that cognition may play in
depression and suggests that biochemical mech-
anisms may be nonspecific.
Strong epidemiologic data point to an associa-
tion between major depressive disorder and in-
creased cardiovascular morbidity and mortality.83
In many patients, cardiovascular disorders precede
depression, and in others, depression precedes the
cardiovascular disorder. Both n−3 fatty acid defi-
ciency84 and elevated plasma homocysteine levels85
have been implicated in cardiovascular disease and
in depression. Elevated cortisol levels in depres-
sion could increase the risk of coronary artery
disease, since cortisol increases visceral fat.64,86
Antidepressant treatment increases the survival
rate among patients who become depressed after
coronary occlusion.86 Endothelial-cell signaling
plays a crucial role in brain neurogenesis,87 and
these cells secrete BDNF; thus, both depression
and cardiovascular disease could be examples of
an endothelial disorder. Signs of inf lammatory
processes have been described in major depres-
sion88 and in cardiovascular disease. Some data
suggest that exercise has protective or therapeu-
tic effects in depression.89 Rodent models support
this possibility.90

Table 2 summarizes possible pathophysiological
mechanisms of depression other than those based
on the monoamine-deficiency hypothesis or the
roles of stress, cortisol, and neurogenesis. Many
of these other proposed mechanisms have also
been implicated in psychiatric and neurologic dis-
orders other than depression. Since the compo-
nents of the brain are highly interconnected, it is
not difficult to find possible integrative frame-
works between two or more of the various theo-
ries. Testing the theories in a manner that can re-

ject the null hypothesis has been more difficult.
Research in depression has sometimes been se-
quentially imitative of dominant ideas in related
fields, such as neurogenesis, glutamate neurotrans-
mission, and nicotinic receptors, instead of pro-
gressing on its own path.
S u m m a r y
It would be appealing to attempt to categorize de-
pression in terms of monoamine-depletion forms
that are perhaps related to genes coding for en-
zymes involved in neurotransmission and cortisol-
related forms that are characterized by a more
long-term course, hippocampal atrophy, and a his-
tory of psychosocial stress. However, the clinical
data do not fall into such neat categories, since
monoamine-based antidepressants are most effec-
tive in patients with severe depression when cor-
tisol levels remain high after the administration
of dexamethasone.
Major depressive disorder is likely to have a
number of causes. Middle-aged or elderly patients
presenting with depression may have a disorder
related to cardiovascular disease and originating
from endothelial dysfunction.128 Patients in their
late teens or early 20s who have severe depression
may have important genetic risk factors and a high
risk of manic episodes.8 In patients with an anx-
ious and depressive personality, depression may
be due to genetically determined personality fac-
tors11 or adverse childhood experiences.129
Avoidance of premature closure on any one
scientific theory of the mechanism of depression
will best serve the search for new, more effective
treatments. It is likely that the pathogenesis of
acute depression is different from that of recurrent
or chronic depression, which is characterized by
long-term declines in function and cognition.
Mood can be elevated (by stimulants,46 by brain
stimulation,123 or by ketamine94) or depressed (by
monoamine depletion19 in recovered patients) for
short periods, but longer-term improvement may
require reduction of the abnormal glucocorticoid
function induced by stress or increases in brain
neurotrophic factors.
No potential conflict of interest relevant to this article was
reported.

Hi Raquel,
for me, the most important thing when it comes to protein
shakes is the flavor. Your idea for offering samples of the
protein shakes is great because even if your product is cost
effective, consumers will not purchase your product if the
flavor doesn’t appease to them. The quality of your product is
your opportunity, then the safety of your product and
production of your product then your low price protein shakes
will surely secure your opportunity.
Hello Jasmin Hottle,
I think it's hard to see your product as different compared to
other products. What are you trying to bring to the marketplace
today? Do you have a target audience in mind that you’re trying
to sell your product to? I think if we are looking at a product
then we need to look at what others are bringing to the market
and what they target and then target audiences that are untapped
resources and haven’t been targeted. This will also give you
more monetary opportunities in today’s fast paced marketplace
where most business don’t last more than a year.
NON-ALCOHOLIC BEVERAGE COMPANY PORTFOLIO
(The NAB Company Portfolio will have lists of things that the
BUS599 students would be able to sort
through to conduct a SWOT Analysis and to apply to
appropriate sections of the NAB Business Plan. )
Note #1:
This is the compilation of Data, Notes, and Information that
have been put together to create a
Business Plan for a start-up company in the non-alcoholic
beverage industry.
The goal of my business plan is twofold:
1. To help identify and outline all the issues I will need to
address in starting this company.
2. To present to funders to help raise money to finance this
company.
NAB Background:
Melinda Cates has been selling her NAB at County Fairs for the
past 7 years for $2 a bottle. She
sells an average of 10 Cardboard cartons each weekend a
County Fair is open. From her
calculations, it takes $.56 to make a bottle of NAB when she
calculates all the NAB ingredients
and the cost of the bottle and cap. Her rich uncle, Bill, just died
and left her a small monetary
inheritance. However, since he so enjoyed her home-made NAB,
he also left her equipment to
start a small NAB business.
Melinda and I have been close, trusted friends for years. She
found out that I just earned my
MBA from Strayer University, and she asked me to help her get
her NAB business up and
running.
I have agreed to put together a NAB Business Plan, and I have
agreed to be the CEO/President of
the company for at least the next five years.
NAB Today:
Parameters for New Company
Here are the parameters in which I must work.

other words, I do not need to take a salary/draw for myself for
six months of projections.
I am assuming I can live off my personal savings.

Personnel:
Myself: I have collected $20,000 from friends and relatives who

interest or by the end of the second

inheritance
Other colleagues with specific skills and talents:
Ian Glass: retired PepsiCo plant production line foreman. Ian
recently retired with 35 years of
loyal PepsiCo service in every position from janitor to
production line foreman, and he and his
wife moved into your neighborhood. He is tickled that you have
asked him to help develop a
plan to get the NAB Company’s production line going. He said
he can help organize and sit on
the planning committee as a non-paid member until the NAB
company can hire its own
Production Line Foreman. He hinted that he retired from
PepsiCo with an annual salary of
$55,000, but he says that’s just the starting salary that large
companies pay their foremen who
are in an apprenticeship program. He doesn’t think the NAB
Company will have to pay top
dollar for someone who has the willingness to join the NAB
company as a start up!
Mary Cates, JD: Melinda’s sister who was a senior executive
with the Federal Trade
Commission from 2001-2012. She left the FTC after a
significant 30 year career with the federal
government in which she lead the research and support of
numerous federal court findings
against companies that violated consumer deception and unfair
practices laws. She would enjoy
serving on the initial company planning group to make sure her
sister’s recipe is successfully
shared within the state!

Health concerns
Another major reason is the shift in consumer preferences
toward healthier products. Carbonated
soft drink makers have faced severe criticism from health
officials, governments, and
communities alike for the ill-effects of high sugar content,
artificial sweeteners, and other
harmful ingredients in their products, including those in diet
soda variants. Consumers are
also more conscious of the health risks associated with soft
drinks such as obesity and nutritional
deficiencies, especially in youth. As a result, they’re opting for
other beverages that are noncarbonated
and have fewer calories.
The World Health Organization suggests that sugar should
account for only 5% of total energy
intake per day. That’s around 25 grams of sugar per day for an
adult of normal body mass index.
Health officials feel that this percentage should be even lower
for a better quality of life. A single
soda can contains around 40 grams of sugar.
The soda tax
Mexico, which has the highest rates of obesity in the world, has
imposed a 10% tax on sugary
beverages to discourage the consumption of these drinks. There
is a strong possibility that many
other countries will introduce a soda tax to reduce sugar
consumption through carbonated drinks.
In the next part of this series, we’ll discuss how soft drink
makers including The Coca-Cola
Company (KO), PepsiCo, Inc. (PEP), Dr Pepper Snapple Group,
Inc. (DPS), and Monster
Beverage Corporation (MNST) are sustaining business under
such challenging conditions. CocaCola
and PepsiCo are part of the Consumer Staples Select Sector
SPDR ETF (XLP).
D. Key indicators of the non-alcoholic beverage industry
By Sharon Bailey • Nov 20, 2014 12:09 pm EST
Factors influencing sector growth
The non-alcoholic beverage industry falls under the consumer
staples category (XLP), which is
non-cyclical in nature compared to the consumer discretionary
sector. In this part of the series,
we’ll look at the factors that impact the growth of the non-
alcoholic beverage industry.
Consumption expenditure
The Bureau of Economic Analysis (or BEA) releases the
personal income and outlays monthly
reports that indicate changes in individuals’ personal incomes,
savings, and expenditures.
US consumption spending accounts for over two-thirds of the
country’s gross domestic product
(or GDP). The US real personal consumption expenditure for

we’ll discuss why CSDs have been losing popularity, and why
sales of other
beverages, including juices and ready-to-drink tea, are
increasing.
Major companies
The non-alcoholic beverage market is a highly competitive
industry that includes two behemoths
—The Coca-Cola Company (KO) and PepsiCo, Inc. (PEP).
Collectively, these companies hold
about 70% of the US CSD market. Dr Pepper Snapple Group,
Inc. (DPS), Monster Beverage
Corporation (MNST), and Cott Corporation (COT) are some
other key players in the CSD
market.
Many international markets are also dominated by Coca-Cola
and PepsiCo, but include other
companies such as Groupe Danone, Nestle SA, and Suntory
Holdings Limited.
Non-alcoholic beverage manufacturers, like Coca-Cola and
PepsiCo, are part of the consumer
staple sector. You can invest in these companies through the
Consumer Staples Select Sector
SPDR ETF (XLP).
G. Statistics and facts on non-alcoholic beverages and soft
drinks
The non-alcoholic beverages industry encompasses liquid
refreshment beverages (LRB) such as
bottled water, carbonated soft drinks, energy drinks, fruit
beverages, ready-to-drink coffee and
tea, sports beverages and value-added water.

Belmaker, M.D., and Galila Agam, Ph.D. From Ben Gurion University of the Negev, Beersheba, Israel. Address reprint requests to Dr. Belmaker at Beersheba Mental Health Center, P.O. Box 4600, Beersheba, Israel, or at [email protected] N Engl J Med 2008;358:55-68. Copyright © 2008 Massachusetts Medical Society. Depression is related to the normal emotions of sadness and bereavement, but it does not remit when the external cause of these emo-tions dissipates, and it is disproportionate to their cause. Classic severe states of depression often have no external precipitating cause. It is difficult, however, to draw clear distinctions between depressions with and those without psychosocial precipitating events.1 The diagnosis of major depressive disorder requires a distinct change of mood, characterized by sadness or irritability and accompanied by at least several psychophysiological changes, such as disturbances in
  • 2. sleep, appetite, or sex- ual desire; constipation; loss of the ability to experience pleasure in work or with friends; crying; suicidal thoughts; and slowing of speech and action. These chang- es must last a minimum of 2 weeks and interfere considerably with work and fam- ily relations. On the basis of this broad definition, the lifetime incidence of depres- sion in the United States is more than 12% in men and 20% in women.2 Some have advocated a much narrower definition of severe depression, which they call melan- cholia or vital depression.3 A small percentage of patients with major depression have had or will have manic episodes consisting of hyperactivity, euphoria, and an increase in pleasure seeking. Although some pathogenetic mechanisms in these cases and in cases of major depres- sive disorder overlap, a history of mania defines a distinct illness termed bipolar dis- order.4 Depression is a heterogeneous disorder with a highly variable course, an inconsis- tent response to treatment, and no established mechanism. This review presents the major current approaches to understanding the biologic mechanisms of major de- pression. G e n e t i c s Studies comparing concordance rates for major depression
  • 3. between monozygotic and dizygotic twins suggest a heritability of about 37%,5 which is much lower than the heritability of bipolar disorder or schizophrenia. Some aspects of the normal person- ality, such as avoidance of harm, anxiousness, and pessimism, are also partly heritable.6 Kendler et al.7 showed that although depression is due in part to heritable depression- prone personality traits, it is also the result of heritable factors that are independent of personality. Early-onset, severe, and recurrent depression may have a higher heri- tability than other forms of depression.8 It is clear from studies of families that major depression is not caused by any single gene but is a disease with complex genetic fea- tures. Studies of pedigrees with multiple cases of major depression have identified chromosomal regions with linkage to the disorder, and some of these loci have been replicated in more than one study, although no single chromosomal region has been replicated in every family study of genetic linkage in depression. Holmans et al.9 found T h e n e w e n g l a n d j o u r n a l o f m e d i c i n e n engl j med 358;1 www.nejm.org january 3, 200856 evidence of linkage of recurrent, early-onset de- pression to chromosome 15q25-q26, but the pop- ulation attributable risk was small.
  • 4. No specific molecular risk factor has been reli- ably identified. One common polymorphic variant of the serotonin-transporter–linked polymorphic region (5-HTTLPR), which affects the promoter of the serotonin-transporter gene, causes reduced uptake of the neurotransmitter serotonin into the presynaptic cells in the brain.10 Some studies have shown that this polymorphism confers a predis- position to depression,11 but it also confers a pre- disposition to an anxious and pessimistic person- ality.10 Brain imaging reveals functional differences in emotion-related areas of the brain among car- riers of the different common polymorphisms of 5-HTTLPR,12 although a direct relation to depres- sion is unclear. In a large, prospective epidemio- logic study, Caspi et al.13 found that 5-HTTLPR predicted depression only in association with de- fined life stresses. Some environmental factors could confer a predisposition to depression by af- fecting the genome epigenetically — for example, increased maternal care in rodents causes an epi- genetic change in the promoter region of the glu- cocorticoid-receptor gene.14 T h e M o n o a m i n e - D e f i c i e n c y H y p o t h e s i s The noradrenergic and serotonergic systems orig- inate deep in the brain and fan out over almost the entire brain, suggesting a system capable of modulating many areas of feeling, thinking, and behaving. The early antidepressants blocked the reuptake of norepinephrine and serotonin by the presynaptic neuron. The immediate effects of this pharmacologic action are to increase the availabil- ity of norepinephrine and serotonin in the synapse
  • 5. and to increase stimulation of the postsynaptic neuron. Inhibitors of the enzyme monoamine oxi- dase were also discovered to have antidepressant properties. This enzyme catabolizes norepineph- rine and serotonin in their respective presynaptic neurons, and such inhibition could be expected to increase the availability of neurotransmitters. These discoveries led to a major theory of depression known as the monoamine-deficiency hypothesis. Numerous studies of norepinephrine and serotonin metabolites in plasma, urine, and cerebrospinal fluid, as well as postmortem studies of the brains of patients with depression, have yet to identify the purported deficiency reliably. However, a newly dis- covered form of the enzyme tryptophan hydroxy- lase, designated TPH-2, is specific to the brain15 and could explain why previous postmortem stud- ies of total enzyme activity did not show differ- ences in tryptophan hydroxylase activity between patients with depression and controls.16 A recent positron-emission tomographic study using a li- gand for brain monoamine oxidase showed a 30% increase of the enzyme in a subgroup of patients with depression.17 A study measuring differences in monoamine metabolites between the internal jugular vein and the brachial artery showed lower production by the brain of norepinephrine metabo- lites in patients with depression than in controls.18 The monoamine-deficiency hypothesis continues to stimulate research whenever a new technical window into the brain is opened. Serotonin and norepinephrine can be depleted experimentally in humans by oral treatments.19 A drink containing all amino acids except trypto-
  • 6. phan stimulates the liver to synthesize proteins and rapidly depletes the plasma (and therefore the brain) of tryptophan. Tryptophan is rate-limiting for serotonin synthesis in the brain. Such oral tryptophan depletion does not induce depression in healthy subjects but will cause a relapse of de- pression in patients who have been successfully treated with a serotonin-reuptake inhibitor.19 Sim- ilarly, α-methyl paratyrosine inhibits tyrosine hy- droxylase, the rate-limiting step in catecholamine synthesis. Treatment with α-methyl paratyrosine does not induce depression in normal subjects but will induce a relapse in patients who have been treated successfully with a norepinephrine-reup- take inhibitor.19 These findings suggest that nor- epinephrine and serotonin have critical roles in the mechanisms of these treatments of depression but that additional neurochemical factors are neces- sary to cause depression. Because direct measurements of monoamine neurotransmission did not yield definitive findings in relation to depression, the downstream effects of monoamine neurotransmission were explored (Fig. 1). The serotonin-1B receptor is located pre- synaptically and regulates the release of serotonin by feedback inhibition. Postmortem studies show that the levels of p11, a protein that enhances the efficiency of serotonin-1B receptor signaling, are decreased in the brains of patients with depres- sion.20 The serotonin-1A receptor is located both presynaptically and postsynaptically to regulate mech a nisms of dise a se
  • 7. n engl j med 358;1 www.nejm.org january 3, 2008 57 serotonin function (Fig. 1). The receptor can be evaluated in patients with depression by injecting specific agonists and measuring specific neuro- endocrine responses, such as elevation of the pro- lactin level.21 Results suggest that the sensitivity of this receptor is reduced in patients with depres- sion.21 The α2-noradrenergic receptor, which is usually presynaptic, modulates norepinephrine re- lease by feedback inhibition (Fig. 1). Heightened receptor sensitivity has been described in patients with depression,22 which is consistent with re- duced norepinephrine release. It is conceivable that the second-messenger sys- tems for serotonergic and noradrenergic neuro- transmission malfunction in depression, and for this reason the phosphatidylinositol and cyclic AMP second-messenger systems have been exten- sively evaluated. Reduced inositol levels have been found in postmortem studies of the brains of per- sons who have died by suicide23 and in magnetic resonance spectroscopic studies of the frontal cor- tex in patients with depression.24 A blunted cyclic AMP response to stimulation was found in post- mortem studies of the brains of patients with de- pression.25 These reductions in second-messenger function may impair neurotransmitter function even without changes in monoamine levels or re- ceptor numbers. These data indirectly support elaborations of the original monoamine-deficiency hypothesis of depression (Fig. 1). G proteins that mediate signaling between re-
  • 8. ceptors and second-messenger systems have also been investigated in patients with depression, both in postmortem studies of the brain26 and in stud- ies of peripheral-blood cells.27 Although these systems are clearly affected, no consistent picture has emerged because there are numerous forms of G proteins that vary in different areas of the brain. The cyclic AMP response element–binding protein (CREB) is a transcription factor affected by cyclic AMP in the cell. In an animal model of de- pression, rats with overexpression of CREB in the dentate gyrus behaved similarly to rats treated with antidepressants, but the opposite effect was found when CREB was overexpressed in the nu- cleus accumbens.26,28 Thus, the role of CREB in depression is specific to the region of the brain. Most but not all studies show that long-term treat- ment with antidepressants stimulates CREB func- tion, possibly depending on the type of drug and the dosage.28 Levels of CREB and phospho-CREB were reduced in postmortem studies of the cor- texes of patients who had a major depressive disorder and had not taken antidepressants, as compared with controls.26,28 Many studies of sec- ond-messenger systems and transcription factors in depression were inspired by the belief that it takes several weeks before antidepressant treat- ment has an effect; consequently, the studies were designed to detect time-dependent biochemical changes in the cell. New meta-analyses suggest that antidepressant effects begin rapidly, howev- er,29 thereby supporting the classic monoamine- deficiency hypothesis. A strong point of the monoamine theory has
  • 9. been its predictive power. Almost every compound that has been synthesized for the purpose of in- hibiting norepinephrine or serotonin reuptake has been proved to be a clinically effective antidepres- sant. A behavioral model of depression has been developed in which a rodent is placed in a glass cylinder filled with water, the sheer wall offering no chance of escape. The animal struggles for a while and then floats passively (the forced swim test). A single prior injection of antidepressant in- creases the struggling time; results in this model have excellent predictive validity for new antide- pressants. Other animal models have been devel- oped by selective breeding of rats for depression- like behavior, and these genetically susceptible rodents also have a response to antidepressants.30 Still other models that can be studied biochemi- cally induce depression with the use of long-term mild stress or learned helplessness. However, no animal model of depression captures the periodic change of behavior into and out of depression that is seen in patients with depression. Molecular techniques such as gene knockout partially support the monoamine theory of depres- sion. The serotonin-reuptake–transporter knock- out mouse is excessively anxious and characterized by increased immobility in the forced swim test.31 This effect is similar to that of the low-activity polymorphic variant of the serotonin receptor on human personality10 but is the opposite of the ex- pected effects of serotonin-reuptake–inhibitor an- tidepressants. However, this inconsistency could be explained by the difference between a chron- ic monoamine abnormality during brain develop- ment31 and the hypothesized acute monoamine

The effects of stimulants on mood indirectly T h e n e w e n g l a n d j o u r n a l o f m e d i c i n e n engl j med 358;1 www.nejm.org january 3, 200858 support the monoamine-deficiency hypothesis of depression and show that mood can be altered rapidly. Cocaine and amphetamines are powerful releasers of monoamines into the synapse as well as inhibitors of reuptake. Their mood-elevating effects are immediate, but in patients with severe depression they have often been reported to cause agitation rather than relief of depression. This finding could reflect the ability of these stimulants to deplete the presynapse of monoamines and thus cause a “crash” into depression. Recent studies support the theory that an acute response to a single dose of amphetamine predicts a patient’s longer-term response to monoamine-reuptake in- hibitors.46 The role of dopamine deficiency in depression is suggested by the frequency of depression in pa- tients with Parkinson’s disease and the effect of reserpine, which depletes serotonin, norepineph- rine, and dopamine, causing a hypoactive state in animals. The antidepressant agent buproprion in- hibits the reuptake of dopamine. Some direct do- pamine-receptor agonists, such as pramipexole,
  • 11. have been reported to be efficacious in the treat- ment of depression, even though they were devel- oped for Parkinson’s disease.47 A major liability of the monoamine-deficiency hypothesis is its derivation from the mechanism of currently available antidepressants. Approxi- mately two thirds of patients have a clinical re- sponse to these agents, whereas one third have a response to placebo.48 Perhaps the mechanism of depression is not related to monoamines in two of three cases.

This stimulus results in the se- cretion of corticotropin into plasma, stimulation of corticotropin receptors in the adrenal cortex, and release of cortisol into the blood. Hypothalam- ic cortisol receptors respond by decreasing CRH production to maintain homeostasis (Fig. 2). There is considerable evidence that cortisol and its central releasing factor, CRH, are involved in depression.50,51 Patients with depression may have elevated cortisol levels in plasma,38 elevated CRH levels in cerebrospinal fluid,50 and increased levels of CRH messenger RNA and protein in limbic brain regions.50 In studies using dexa-

The Monoamine-Deficiency Hypothesis Extended. The monoamine hypothesis of depression postulates a deficiency in serotonin or norepinephrine neurotrans- mission in the brain. Monoaminergic neurotransmis- sion is mediated by serotonin (5-hydroxytryptamine 1A [5-HT1A] and 5-hydroxytryptamine 1B [5-HT1B]) or norepinephrine (noradrenaline) released from presyn- aptic neurons (serotonergic neuron, shown on the left side, and noradrenergic neuron, shown on the right side [condensed virtually]). Serotonin is synthesized from tryptophan, with the first step in the synthetic pathway catalyzed by tryptophan hydroxylase; norepi- nephrine is synthesized from tyrosine, with the first step catalyzed by tyrosine hydroxylase. Both mono- amine transmitters are stored in vesicles in the presyn- aptic neuron and released into the synaptic cleft, there- by affecting both presynaptic and postsynaptic neurons. Cessation of the synaptic action of the neu- rotransmitters occurs by means of both reuptake through the specific serotonin and norepinephrine transporters and feedback control of release through the presynaptic 5-HT1A and 5-HT1B regulatory autore- ceptors for serotonin and the α2-noradrenergic autore- ceptors for norepinephrine. Monoamine oxidase A (MAO-A) catabolizes monoamines presynaptically and thereby indirectly regulates vesicular content. The pro- tein p11, which interacts with 5-HT1B receptors, in- creases their function. Postsynaptically, both serotonin and norepinephrine bind two kinds of guanine nucleo-
  • 13. tide triphosphate–binding protein (G protein)–coupled receptors: cyclic AMP (cAMP)–coupled receptors, which activate adenylate cyclase (AC) to generate cAMP, and phosphatidylinositol (PI)–coupled recep- tors, which activate phospholipase C (PLC). PLC gener- ates inositol triphosphate (IP3) and diacylglycerol (DAG); cAMP activates protein kinase A (PKA), and IP3 and DAG activate protein kinase C (PKC). The two pro- tein kinases affect the cAMP response element–bind- ing protein (CREB). Findings in patients with depres- sion that support the monoamine-deficiency hypothesis include a relapse of depression with inhibi- tion of tyrosine hydroxylase or depletion of dietary tryptophan, an increased frequency of a mutation af- fecting the brain-specific form of tryptophan hydroxy- lase (TPH-2), increased specific ligand binding to MAO-A, subsensitive 5-HT1A receptors, malfunction- ing 5-HT1B receptors, decreased levels of p11, poly- morphisms of the serotonin-reuptake transporter asso- ciated with depression, an inadequate response of G proteins to neurotransmitter signals, and reduced lev- els of cAMP, inositol, and CREB in postmortem brains. mech a nisms of dise a se n engl j med 358;1 www.nejm.org january 3, 2008 59 verely depressed patients.52 Antidepressant-induced clinical remission is accompanied by reversal of some of these abnormalities.52 Adults with a history of physical or sexual abuse as children have increased levels of CRH in cerebrospinal fluid.53 Adult rodents that were sepa-

CRH-receptor an- tagonists show antidepressant activity in animal models,57 but the results of large clinical trials have been disappointing. A compound that blocks the glucocorticoid receptor has been reported to be efficacious in depression, but only the most severe and psychotic type.58 A single test for the cortisol level in blood does not contribute to the diagnosis of depression, since levels of cortisol vary markedly in a circadian rhythm38 and because the overlap between values in patients and those in controls is considerable.
  • 20. Mild stress induced in the laboratory, such as Figure 2. The Hypothalamic–Pituitary–Cortisol System in Depression. The hypothalamic–pituitary–cortisol hypothesis of depression postulates that abnormalities in the cortisol response to stress may underlie depression. The black arrows show that in response to stress, which is perceived by the brain cortex and the amygdala and transmitted to the hypothalamus, corticotropin-releasing hormone (CRH) is released, inducing the anterior pituitary gland to secrete corticotropin into the bloodstream. Corticotropin stimulates the ad- renal cortexes to secrete the glucocorticoid hormone cortisol. The red lines show that cortisol, in turn, induces feed- back inhibition in the hypothalamus and the pituitary, suppressing the production of CRH and corticotropin, respec- tively. Findings in patients with depression that support the hypothalamic–pituitary–cortisol hypothesis include the following: cortisol levels are sometimes increased in severe depression, the size of the anterior pituitary and adrenal cortex is increased, and CRH levels in the cerebrospinal fluid and CRH expression in the limbic brain regions are in- creased. Hippocampal size and the numbers of neurons and glia are decreased, possibly reflecting reduced neuro- genesis due to elevated cortisol levels or due to reduced brain- derived neurotrophic factor.

  • 99. patients with depression and those in controls.38 It is possible that chronic mild elevations of cor- tisol, especially at night, when cortisol levels in normal subjects are very low, have a pathogenic role in depression. It is also possible that periph- eral cortisol elevations are only a ref lection of central disturbances in CRH signaling, which me- diate the effects of environmental stress on mood.59 A major liability of the hypothalamic–pituitary– adrenal axis theory of depression is the difficulty of defining the relationship of stress to depres- sion. Some patients have a single lifetime depres- sive episode, whereas a larger proportion have a recurrent or even chronic course. Various types of acute stress, early childhood trauma, or long- term psychosocial problems may be involved and may lead to different responses of the stress sys- tem. Stress may be causative in some cases and secondary to depressed mood in others. Severe stress in rodents does not necessarily model the common stresses of childhood. The association of abuse in childhood with psycho- pathologic disorders, including depression, in adulthood could be due to common factors link- ing family perpetrators of abuse and their victims, including not only shared genes but also a shared environment of poverty, poor nutrition, and poor prenatal care. Depression is not uncommon in people with no psychosocial risk factors. Most patients treated for depression have no evidence of hypothalamic–pituitary–adrenal dysfunction, just as most such patients have no direct evidence of brain monoamine deficiency. The classic teaching is that neurons do not di-

Neurogenesis is more prominent in rodents than in primates,60 and some have questioned whether it occurs in the human cortex.61 Elevated levels of glucocorticoids can reduce neurogenesis, and this has been suggested as a mechanism for the de- creased size of the hippocampus on magnetic resonance images of the brain in many patients with depression.62 In postmortem studies of pa- tients with depression, cell loss in the subgenual prefrontal cortex, atrophy in the dorsolateral pre- frontal cortex and the orbitofrontal cortex, and T h yr o xi n e ab n o rm al it ie s

T h e n e w e n g l a n d j o u r n a l o f m e d i c i n e n engl j med 358;1 www.nejm.org january 3, 200864 increased numbers of cells in the hypothalamus and the dorsal raphe nucleus have been reported.63 These effects resemble the atrophic changes in the brain in patients with Cushing’s disease64 and in rodents treated with glucocorticoids.65 However, cortisol elevations in depression are much lower than in Cushing’s disease. Restraint in a small container induces stress in rodents, suppressing neurogenesis, and this effect is countered by antidepressant treatment.66 An- tidepressants also enhance neurogenesis in non- human primates.67 Santarelli et al.68 irradiated the hippocampus in mice and abolished neurogene- sis. They found that the radiation also abolished the ability of the animals to respond behaviorally to antidepressant treatment in the forced swim test, but this phenomenon does not occur in every mouse strain studied.69 Henn and Vollmayr sum- marized other studies providing evidence that de- creased neurogenesis is a result of stress and anxiety but may not be behaviorally relevant.70 The relevance of animal models of neurogenesis to clinical studies of depression has been questioned by analogy with studies of neuroprotection strat- egies in stroke, for which numerous findings in animal models have not been replicated in hu- man studies.71
  • 131. Brain-derived neurotrophic factor (BDNF), a neurotrophic peptide, is critical for axonal growth, neuronal survival, and synaptic plastic- ity,72 and its levels are affected by stress73 and cortisol.74 A postmortem study of patients with depression who had committed suicide showed that BDNF was reduced in the hippocampus.75 Antidepressant drugs and electroconvulsive thera- py up-regulate BDNF and other neurotrophic and growth factors75,76; a single bilateral infusion of BDNF into the dentate gyrus has antidepressant- like effects.77 One study showed that the hippo- campus was smaller than normal in patients with depression who carried a met166 BDNF allele.78 In an animal model of depression, epigenetic his- tone methylation mediated down-regulation of BDNF transcripts and antidepressant treatment reversed this effect.79 These studies suggest that BDNF is the link among stress, neurogenesis, and hippocampal atrophy in depression. However, a genetic association of the BDNF val166met poly- morphism with depression has not been replicated in most studies,74 and BDNF may be related not only to depression but to multiple psychiatric dis- orders.74 BDNF-knockout mice have behaviors un- related to depression.45 Reduced BDNF levels in the peripheral blood of patients with depression seem to derive almost entirely from blood plate- lets,80 and many artifacts must therefore be con- sidered in interpreting these findings. Inflamma- tion in the brain and some neurotoxins increase brain BDNF levels, suggesting that the actions of BDNF are not uniformly therapeutic.81 Castrén82 has proposed that antidepressant treatments may increase synaptic sprouting and allow the brain
  • 132. to use input from the environment more effec- tively to recover from depression. This hypothe- sis highlights the role that cognition may play in depression and suggests that biochemical mech- anisms may be nonspecific. Strong epidemiologic data point to an associa- tion between major depressive disorder and in- creased cardiovascular morbidity and mortality.83 In many patients, cardiovascular disorders precede depression, and in others, depression precedes the cardiovascular disorder. Both n−3 fatty acid defi- ciency84 and elevated plasma homocysteine levels85 have been implicated in cardiovascular disease and in depression. Elevated cortisol levels in depres- sion could increase the risk of coronary artery disease, since cortisol increases visceral fat.64,86 Antidepressant treatment increases the survival rate among patients who become depressed after coronary occlusion.86 Endothelial-cell signaling plays a crucial role in brain neurogenesis,87 and these cells secrete BDNF; thus, both depression and cardiovascular disease could be examples of an endothelial disorder. Signs of inf lammatory processes have been described in major depres- sion88 and in cardiovascular disease. Some data suggest that exercise has protective or therapeu- tic effects in depression.89 Rodent models support this possibility.90 O t h e r P o s s i b l e M e c h a n i s m s Table 2 summarizes possible pathophysiological mechanisms of depression other than those based on the monoamine-deficiency hypothesis or the roles of stress, cortisol, and neurogenesis. Many
  • 133. of these other proposed mechanisms have also been implicated in psychiatric and neurologic dis- orders other than depression. Since the compo- nents of the brain are highly interconnected, it is not difficult to find possible integrative frame- works between two or more of the various theo- ries.

S u m m a r y It would be appealing to attempt to categorize de- pression in terms of monoamine-depletion forms that are perhaps related to genes coding for en- zymes involved in neurotransmission and cortisol- related forms that are characterized by a more long-term course, hippocampal atrophy, and a his- tory of psychosocial stress. However, the clinical data do not fall into such neat categories, since monoamine-based antidepressants are most effec- tive in patients with severe depression when cor- tisol levels remain high after the administration of dexamethasone. Major depressive disorder is likely to have a number of causes. Middle-aged or elderly patients presenting with depression may have a disorder related to cardiovascular disease and originating from endothelial dysfunction.128 Patients in their late teens or early 20s who have severe depression may have important genetic risk factors and a high risk of manic episodes.8 In patients with an anx- ious and depressive personality, depression may be due to genetically determined personality fac- tors11 or adverse childhood experiences.129 Avoidance of premature closure on any one scientific theory of the mechanism of depression will best serve the search for new, more effective treatments. It is likely that the pathogenesis of acute depression is different from that of recurrent or chronic depression, which is characterized by long-term declines in function and cognition.
  • 139. Mood can be elevated (by stimulants,46 by brain stimulation,123 or by ketamine94) or depressed (by monoamine depletion19 in recovered patients) for short periods, but longer-term improvement may require reduction of the abnormal glucocorticoid function induced by stress or increases in brain neurotrophic factors. No potential conflict of interest relevant to this article was reported. We thank Herman van Praag, who inspired our work on de- pression over the course of three decades.

  • 165. Hi Raquel, for me, the most important thing when it comes to protein shakes is the flavor. Your idea for offering samples of the protein shakes is great because even if your product is cost effective, consumers will not purchase your product if the flavor doesn’t appease to them. The quality of your product is your opportunity, then the safety of your product and production of your product then your low price protein shakes will surely secure your opportunity. Hello Jasmin Hottle, I think it's hard to see your product as different compared to other products. What are you trying to bring to the marketplace today? Do you have a target audience in mind that you’re trying to sell your product to? I think if we are looking at a product then we need to look at what others are bringing to the market and what they target and then target audiences that are untapped resources and haven’t been targeted. This will also give you more monetary opportunities in today’s fast paced marketplace where most business don’t last more than a year. NON-ALCOHOLIC BEVERAGE COMPANY PORTFOLIO (The NAB Company Portfolio will have lists of things that the BUS599 students would be able to sort through to conduct a SWOT Analysis and to apply to appropriate sections of the NAB Business Plan. ) Note #1: This is the compilation of Data, Notes, and Information that have been put together to create a Business Plan for a start-up company in the non-alcoholic beverage industry. The goal of my business plan is twofold: 1. To help identify and outline all the issues I will need to address in starting this company.

She sells an average of 10 Cardboard cartons each weekend a County Fair is open. From her calculations, it takes $.56 to make a bottle of NAB when she calculates all the NAB ingredients and the cost of the bottle and cap. Her rich uncle, Bill, just died and left her a small monetary inheritance. However, since he so enjoyed her home-made NAB, he also left her equipment to start a small NAB business. Melinda and I have been close, trusted friends for years. She found out that I just earned my MBA from Strayer University, and she asked me to help her get her NAB business up and running. I have agreed to put together a NAB Business Plan, and I have agreed to be the CEO/President of the company for at least the next five years. NAB Today: Parameters for New Company Here are the parameters in which I must work. ss is a start-up: We are not yet in operation. We already have a “recipe” for a beverage, but we are not yet making sales at any significant level. -alcoholic beverage (NAB).

Stephen Job: Part Time (20 hrs/week) Computer Expert/Assistant: $10/hr Melinda Cates: NAB Creator & Master Mixer (owns the patent on the NAB): has $40,000 inheritance Other colleagues with specific skills and talents: Ian Glass: retired PepsiCo plant production line foreman. Ian recently retired with 35 years of loyal PepsiCo service in every position from janitor to production line foreman, and he and his wife moved into your neighborhood. He is tickled that you have asked him to help develop a plan to get the NAB Company’s production line going. He said he can help organize and sit on the planning committee as a non-paid member until the NAB company can hire its own Production Line Foreman. He hinted that he retired from PepsiCo with an annual salary of $55,000, but he says that’s just the starting salary that large companies pay their foremen who are in an apprenticeship program. He doesn’t think the NAB Company will have to pay top dollar for someone who has the willingness to join the NAB company as a start up! Mary Cates, JD: Melinda’s sister who was a senior executive with the Federal Trade Commission from 2001-2012. She left the FTC after a significant 30 year career with the federal government in which she lead the research and support of numerous federal court findings against companies that violated consumer deception and unfair practices laws. She would enjoy serving on the initial company planning group to make sure her sister’s recipe is successfully shared within the state!

Carbonated soft drink makers have faced severe criticism from health officials, governments, and communities alike for the ill-effects of high sugar content, artificial sweeteners, and other harmful ingredients in their products, including those in diet soda variants. Consumers are also more conscious of the health risks associated with soft drinks such as obesity and nutritional deficiencies, especially in youth. As a result, they’re opting for other beverages that are noncarbonated and have fewer calories. The World Health Organization suggests that sugar should account for only 5% of total energy intake per day. That’s around 25 grams of sugar per day for an adult of normal body mass index. Health officials feel that this percentage should be even lower for a better quality of life. A single
  • 188. soda can contains around 40 grams of sugar. The soda tax Mexico, which has the highest rates of obesity in the world, has imposed a 10% tax on sugary beverages to discourage the consumption of these drinks. There is a strong possibility that many other countries will introduce a soda tax to reduce sugar consumption through carbonated drinks. In the next part of this series, we’ll discuss how soft drink makers including The Coca-Cola Company (KO), PepsiCo, Inc. (PEP), Dr Pepper Snapple Group, Inc. (DPS), and Monster Beverage Corporation (MNST) are sustaining business under such challenging conditions. CocaCola and PepsiCo are part of the Consumer Staples Select Sector SPDR ETF (XLP). D. Key indicators of the non-alcoholic beverage industry By Sharon Bailey • Nov 20, 2014 12:09 pm EST Factors influencing sector growth The non-alcoholic beverage industry falls under the consumer staples category (XLP), which is non-cyclical in nature compared to the consumer discretionary sector. In this part of the series, we’ll look at the factors that impact the growth of the non- alcoholic beverage industry. Consumption expenditure The Bureau of Economic Analysis (or BEA) releases the personal income and outlays monthly reports that indicate changes in individuals’ personal incomes, savings, and expenditures. US consumption spending accounts for over two-thirds of the country’s gross domestic product (or GDP). The US real personal consumption expenditure for non-durable goods measures consume basis.
