Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the structure and function of taste buds.
Describe the relationship between the taste threshold and taste index of common substances.
Explain the chemical basis and signal transduction of taste perception for each type of primary taste sensation.
Recognize different abnormalities of taste perception and their causes.
Key Topics:
Significance of Taste Sensation:
Differentiation between pleasant and harmful food
Influence on behavior
Selection of food based on metabolic needs
Receptors of Taste:
Taste buds on the tongue
Influence of sense of smell, texture of food, and pain stimulation (e.g., by pepper)
Primary and Secondary Taste Sensations:
Primary taste sensations: Sweet, Sour, Salty, Bitter, Umami
Chemical basis and signal transduction mechanisms for each taste
Taste Threshold and Index:
Taste threshold values for Sweet (sucrose), Salty (NaCl), Sour (HCl), and Bitter (Quinine)
Taste index relationship: Inversely proportional to taste threshold
Taste Blindness:
Inability to taste certain substances, particularly thiourea compounds
Example: Phenylthiocarbamide
Structure and Function of Taste Buds:
Composition: Epithelial cells, Sustentacular/Supporting cells, Taste cells, Basal cells
Features: Taste pores, Taste hairs/microvilli, and Taste nerve fibers
Location of Taste Buds:
Found in papillae of the tongue (Fungiform, Circumvallate, Foliate)
Also present on the palate, tonsillar pillars, epiglottis, and proximal esophagus
Mechanism of Taste Stimulation:
Interaction of taste substances with receptors on microvilli
Signal transduction pathways for Umami, Sweet, Bitter, Sour, and Salty tastes
Taste Sensitivity and Adaptation:
Decrease in sensitivity with age
Rapid adaptation of taste sensation
Role of Saliva in Taste:
Dissolution of tastants to reach receptors
Washing away the stimulus
Taste Preferences and Aversions:
Mechanisms behind taste preference and aversion
Influence of receptors and neural pathways
Impact of Sensory Nerve Damage:
Degeneration of taste buds if the sensory nerve fiber is cut
Abnormalities of Taste Detection:
Conditions: Ageusia, Hypogeusia, Dysgeusia (parageusia)
Causes: Nerve damage, neurological disorders, infections, poor oral hygiene, adverse drug effects, deficiencies, aging, tobacco use, altered neurotransmitter levels
Neurotransmitters and Taste Threshold:
Effects of serotonin (5-HT) and norepinephrine (NE) on taste sensitivity
Supertasters:
25% of the population with heightened sensitivity to taste, especially bitterness
Increased number of fungiform papillae
2. Female reproductive system consist of ….
• Tubes
• Uterus Developed from Mullerian ducts
• Vagina
• External genitalia
• Ovaries
Male reproductive sys. Developed from wolfian
ducts .( mesonephric system)
Mullerian ducts ( paramesonephric system )
3. • Male reproductive sys. Developed from wolfian
ducts .( mesonephric system)
• Mullerian ducts ( paramesonephric system )
• Leydig cells in the testis produce testosterone
Sertoli cells in the testis produce antimullerian
hormons which inhibits development of mullerian
sys.
4. • Sexually development and maturation occur in
girls usually the age of 8-9 years.
• During this age hypothalamus starts to
secreting GnRH –its stimulates the pituitary to
secrete gonadotrophins. –gona. Act on the
ovaries to produce folliculogenesis .
• This increase oestrogen levels and brings
physical changes in the body .
5. Physical changes that occurs …
1. Breast development
2. Pubic and axillary hair growth
3. Growth spurt
4. Onset of menstruation (menarche)
Usually menarche occurs around the ages of 12-13
Cycles of first 3-4 years are irregular and
anovulatory.
6. Precocious puberty
Onset if puberty before the age of 8 years
(hormone producing tumours should be considered in
these girls.)
Central precocious puberty (CPP)
is caused due to excess of GnRH ,which susequently
increase the secretion of sex hormones ,LH,FSH.
GnRH analogs are considered drug of choice for cpp
Is cause reversible suppression of reproductive axis and
adult height is preserve in children.
7. Delayed puberty
Secondary sexual characteristics do not occur by
the age of 14 yr. 2 types
1. Hypogonadotrophic hypogonadisum.
2. Hypergonadotrophic hypogonadisum.
8. Hypogonadotropic hypogonadism
• Due to central defect and can be consitutional
(congenital) .
• Other cause are anorexia nervosa, excessive
exercise, chronic illness (diabetic ,renal failure
)
• Rare causes are pituitary tumours and
kalman’s syndrome.
9. Hypergonadotrophic hypogonadism
• Primary ovarian dysfunction occurs despite
high level of pitutary gonadotrophin secretion.
• Turner’s syndrome ( XO )
• Gonadal dysgenesis (XX)
Cause this
11. • Inflammatory bowel disease
• Conduction deafness
• Renal anomalies
They have very streaky ovaries and do not
produce oestrogen
Present with delayed puberty and primary
amenorrohea.
12.
13. 2.XY gonadal dysgenesis
In spite of having XY chromosome pattern
gonads do not develop in to testis.
There fore due to absent of anti mullerian
hormones vagina, uterus and fallopian tubes
develop.
Person is phenotypically female with a XY
chromosomic pattern .
14. Presented with delayed puberty and
amenorrhea
Dysgenetic gonads have high risk of maligancy
there fore need to surgically
removal,(laparoscopically) then strarted on
oestrogen and progesteron containing
contraceptive pills to induce puberty and
maintain withdrawal bleeding.
15. 3. Androgen insensitivity syndrome
Their chromosomal pattern XY but virilization of
external genitalia does not occur,
Present as women will not have vagina, uterus and
follopian due to AMH which secreting by testis.
Testis are usually in the inguinal canal –hernia can
be happen
They present as puberty with amenorrhea and
delayed puberty .
16.
17. Management-
Removal of gonads
Long –term hormone replacement therapy
Once patient is sexually active neo vaginal will
have to be created
18. 4.Congenital adrenal hyperplasia
Progesterone 21-hydroxylase deoxycorticosterone
this ll lead to reduction in the levels of cortisol
According to negative feedback excessive
production of androgen and testosterone leading to
virilization of external genitalia.
Clitoris is enlarged and libia fuses and appears as a
scrotum.
Some patient get ability to produce aldosterone–
salt losing type
19. Management -
Needs early diagnosis
Life long steroid replacement
With hydrocortisone and fludrocortisone for salt
losers
20. 5. Alpha- reductase deficiency
XY karyotype and normally functioning testis
Due to 5-alpha-reductase testosterone cant
convert to dihydrotestosterone in peripheral
tissue.
Virilization does not occur
Present ambiguous genitalia at birth
In puberty testes. level are extremely high
21. 6.Imperforate hymen
Hymen persist as a membrane
Presented with abdominal pain and primary
amenorrhea
O/E- suprapubic lump which haematometron
and distend vagina(haematocolpos) with
menstrual blood
Vulval examination – budging memebrane at the
entrance to the vagina
22. Management –
Making a cruciate shaped incision in the
membrane and let the blood come out on its
own over next few day
23.
24. 7.Other abnormalities of the mullerian system
(abnormality in vagina and uterus )
congenital-
• Duplication of uterus
• Biconuate uterus
• Double vagina
• Septate uterus
• Mullerian agenesis – absent of uterus and upper vagina
(M.a-treatment –Mclndoe’s operation and william’s vuivo-
vaginoplasty surgery)
