CALCI-Q tablets: The Calcium fortified with mineralsSriramNagarajan16
Calcium is very essential in muscle contraction, oocyte activation, building strong bones and teeth, blood clotting,
nerve impulse, transmission, regulating heart beat and fluid balance within cells. The requirements are greatest during
the period of growth such as childhood, during pregnancy, when breast feeding. Long term of calcium deficiency can
lead to oestoporosis in which the bone deteriorates and there is an increased rise of fractures. Eating a well-balanced
calcium supplment like Calci-q tablet can provide all the necessary nutrients and help prevent calcium deficiency.
The present paper Reviews the Role of Calci-Q tablets developed by R&D cell of Sain medicament Pvt Ltd.

Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.
A brief information about the SCOP protein database used in bioinformatics.
The Structural Classification of Proteins (SCOP) database is a comprehensive and authoritative resource for the structural and evolutionary relationships of proteins. It provides a detailed and curated classification of protein structures, grouping them into families, superfamilies, and folds based on their structural and sequence similarities.
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.

2. As dentists, it is vital for us to have a complete
understanding of the general metabolism of calcium
as it helps in the formation and maintenance of the
teeth and their supporting bony structure.
3. Approximately 99% of the total body weight of
calcium is present in the skeleton.
The remaining 1% is found in the cell
membranes and extracellular fluid.
It is this small percentage of calcium that is vital
to all life processes.
4. 1. Contributes to hardness of bone and is a major
component of teeth.
2. Stabilises the cell membrane and their permeability.
3. Maintenance of excitability of nerve and muscles.
4. Normal skeletal and cardiac muscle contraction.
5. Blood coagulation – Ca++ is required for the
conversion of many inactive enzymes in the
coagulation process.
5. Infants (< 1 year) = 300-500 mg/ day
Children (1 – 18 years) = 0.8-1.2 g/day
Adult men and women = 800 mg/day
Pregnancy and lactation = 1.0-2gm/day
6. Milk is a good source for calcium. Calcium content of cow
milk is about 100mg/100ml.
Egg, fish & vegetables are medium source for calcium.
Cereals (wheat, rice) contains small amount of calcium.
But cereals are the staple diet in India. Therefore, cereals
form the major source of calcium in Indian diet.
7. Several different kinds of calcium compounds are used
in calcium supplements. Each compound contains
varying amounts of the mineral calcium.
Common calcium supplements may be labeled as:
Calcium carbonate - Tums® and Caltrate®
Calcium citrate- Citracal® and Solgar®
8. If the calcium in diet and from supplements exceeds
the tolerable upper limit, you could increase your risk
of health problems, such as:
Kidney stones
Prostate cancer
Constipation
Calcium buildup in your blood vessels
Impaired absorption of iron and zinc
9. Calcium absorption in the small intestine occurs by both
active & passive diffusion.
Uptake of calcium by active transport predominates in:
duodenum
jejunum;
Simple diffusion predominates in:
ileum
Most of the ingested calcium is normally eliminated in the
feces, although the kidneys have the capacity to excrete
large amounts by reducing tubular reabsorption of calcium
10. VitaminD –Calcitriol induces the synthesis of the carrier protein
(Calbindin) in the intestinal epithelial cells & so facilitates the
absorption of calcium.
Parathyroid hormones increases calcium transport from the
intestinal cells.
Amino acids, especially lysine & arginine increase absorption.
Lactose : enhance passive Ca uptake; its effect is valuable because of
it presence in milk.
11. Phytates — Phytates are substances found in some plant foods that can bind
calcium in the intestine and decrease its absorption.
Oxalates are present in some leafy vegetables which cause formation of
insoluble calcium oxalates .
In malabsorption syndromes , fatty acid is not absorbed , causing formation
of insoluble calcium salt of fatty acid .
High phosphate content will cause precipitation as calcium phosphate.
Absorption is also decreased with increase intake of protein & fiber in diet.
12. This term is used to describe the amount of Ca++
either stored or lost by the body over a specific period
of time.
When the assimilation of calcium from dietary sources
is less than the metabolic requirements and the
obligatory losses , then calcium is withdrawn from the
skeleton to maintain the critical concentration of the
element in the blood and tissue fluids.
13. Calcium homeostasis is the mechanism by which
the body maintains adequate calcium levels.
Positive Ca2+ balance
Is seen in growing children, where intestinal Ca2+
absorption exceeds urinary excretion and the
difference is deposited in the growing bones.
14. Negative Ca2+ balance
Is seen in women during pregnancy or lactation,
where intestinal Ca2+ absorption is less than
urinary excretion and the difference comes from
the maternal bones.
15. The primary source of available calcium is trabecular
bone, not cortical bone.
The sites of trabecular bone which supply mobile
calcium are the jaws, ribs, bodies of the vertebrae, and
the ends of the long bones.
16. A significant finding from animal experimentation is
that, when skeletal depletion of calcium occurs as a
result of stimulation of the parathyroid gland, alveolar
bone is affected first, the ribs and the vertebrae are
affected second, and the long bones third.
Prolonged depletion results in disorganization and
loss of trabeculae, followed by cortical remodeling or
structural failure.
17. A complex set of interlocking mechanisms takes place
in order to allow man to survive major dietary Ca
intake fluctuations. These mechanisms are mainly
controlled by the endocrine systems.
Three main hormones acting at 3 different sites are
responsible for Ca metabolism.
1. Vit. D3 - Bone.
2. Parathormone - Kidney
3. Calcitonin - Intestine
18. Physiologically active form of vitamin D is a hormone
called calcitriol or 1,25 – dihydroxycholecalciferol
(1,25 – DHCC).
It stimulates Ca uptake by osteoblasts of the bone and
promotes calcification or mineralization and
remodelling , thus increasing the blood calcium
levels.
19.
20. The prime function is to elevate the serum calcium
levels.
Action on kidney – increases Ca reabsorption by
kidney tubules.
Action on bone – decalcification or demineralization
of bone – increase blood Ca levels.
21. Promotes calcification by increasing activity of
osteoblasts.
Decreases bone resorption.
Increases excretion of Ca in urine.
Thus, has a decreasing influence on blood Ca.
22. Estrogen is a hormone that plays an important role in
helping increase calcium absorption.
After menopause, estrogen levels drop and so may
calcium absorption.
Hormone replacement therapy has been shown to
increase the production of vitamin D thus increasing
calcium absorption.
23.
24. Hypercalcemia - Increased level of Ca in the blood.
Symptoms
- Tiredeness
- Loss of appetite.
- Nausea, vomitting.
- Constipation.
Conditions in which it occurs
- Hyperparathyroidism.
- Acute osteoporosis.
- Vit. D intoxication.
- Thyrotoxicosis.
- Polyuria.
- Dehydration.
- Loss of muscle tone.
- Decreased excitability of
muscles and nerves.
25. Hypocalcemia - Decreased levels of Ca in the blood.
Below 8.8mg/dl mild tremors
Less than 7.5mg/dl tetany
Symptoms
- Tetany (Carpopedal spasm).
This occurs in cases of –
- Insufficient Ca in the diet.
- Hypoparathyroidism.
- Insufficient vit. D in the diet.
- Increase in calcitonin levels.
26. Osteoporosis is the most common of all bone diseases in adults,
especially in old age.
It results from diminished organic bone matrix rather than from
poor bone calcification.
In osteoporosis the osteoblastic activity in the bone usually is
less than normal, and consequently the rate of bone osteoid
deposition is depressed.
27. Characterized by demineralization of bone resulting in
progressive loss of bone mass.
Elderly persons (>60 years) of both sexes are at risk.
More predominantly in postmenopausal women.
Etiology – ability to produce calcitriol from vitamin D
is reduced with age.
Results in frequent bone fractures – major cause of
disability.
28. The spine, hips, ribs, and wrists are common areas of
bone fractures from osteoporosis although
osteoporosis-related fractures can occur in almost any
skeletal bone.
Osteoporosis can be present without any
symptoms for decades because osteoporosis
doesn't cause symptoms until bone fractures.
29. Therefore, patients may not be aware of their
osteoporosis until they suffer a painful fracture.
The symptom associated with osteoporotic
fractures usually is pain; the location of the pain
depends on the location of the fracture.
Repeated spinal fractures can lead to chronic lower
back pain as well as loss of height and/or curving
of the spine due to collapse of the vertebrae.
30. Osteoporosis can be described as a lack of bone density or
poverty of bone tissue.
Many patients exhibit continuing bone resorption under
well-made dental prostheses.
These patients return with complaints of discomfort and
inability to tolerate their prostheses, showing rapid,
inexplicable bone loss.
Most of these patients are postmenopausal women.
31. There are many systemic factors which contribute to
alveolar bone loss and decreased ability to tolerate
dental prostheses.
Osteoporosis should always be considered as a
possibility.
The condition of osteoporosis results in bone loss in the
maxillae and mandible as well as in other bones of the
body.
32. Studies have shown that nutritional supplementation
can yield impressive results.
Albanese used a supplement of 750 mg of calcium per
day over a 3-year period and found that the
supplemented patients showed cessation of bone loss
or an increase of up to 12% in bone density when
compared to a test group showing continued bone
loss.
33. Jowsey suggests calcium supplementation of 1,000
mg/day.
Wical and Brussee treated patients with 750 mg of calcium
per day for 1 year.
When compared to a similar
nonsupplemented group, the reduction of bone loss was an
impressive 34% in the maxillae and 39% in the mandible.
In contrast, several studies reported no benefit to bone
density from daily calcium supplementation.
34. Calcium metabolism and
osteoporotic ridge resorption
R. P. Blank, H. A. Diehl, G. T. Ballard, and R. C. Melendez (JPD NOV 1987)
Osteoporosis may be defined simply as a condition of
insufficient bone.
This deficiency undermines skeletal strength, resulting in
fractures that occur with minimal stress in the spine, distal
radius and ulna, and in the femoral neck.
Of the 190,000 hip fractures occurring annually, 80% are in
postmenopausal women.
35. The relationship of osteoporosis to alveolar and
residual ridge resportion is of justifiable concern to the
dental profession.
Although generalized bone loss is characteristic of
osteoporosis, the first sign may be alveolar bone loss,
followed by loss in the vertebrae and long bones.
It may be difficult to treat edentulous patients who
manifest the excessive residual ridge resorption often
associated with osteoporosis.
36. By the time osteoporosis is generally diagnosed, 50%
to 75% of the original bone material has been lost from
the skeleton.
Increasing calcium intake by means of dairy foods and
supplementation is the method most practiced in the
prevention and treatment of osteoporosis to optimize
calcium balance.
37. Studies indicate protection against age-related bone
loss in the hand bones and residual ridge bone with
increased calcium intake.
In contrast, several studies reported no benefit to bone
density from daily calcium supplementation.
This variance in reported data helps to explain the
wide range in recommended dietary calcium intake
from various health organizations.
38. The current recommended dietary allowance (RDA) is
800 mg of calcium/day,
The most recent National Institutes of Health (NIH)
proposal calls for 1000 to 1500 mg of daily calcium.
The World Health Organization (WHO)
recommendation is only 400 to 500 mg of
calcium/day.
Calcium intake in most populations around the
world is 300 to 500 mg/day without any evidence
of osteoporosis.
39. Bone resorption of residual ridges is common. The rate
of resorption varies among different individuals and
within the same individual at different times.
Factors related to the rate of resorption are divided
into anatomic, metabolic, functional, and prosthetic
factors.
40. Anatomic factors include the size, shape, and density
of ridges, the thickness and character of the mucosa
covering, and the ridge relationships.
Metabolic factors include all of the multiple
nutritional, hormonal, and other metabolic factors
which influence the relative cellular activity of the
boneforming cells (osteoblasts) and the bone
resorbing cells (osteoclasts).
41. Functional factors include the frequency, intensity,
duration, and direction of forces applied to bone
which are translated into cellular activity, resulting in
either bone formation or bone resorption.
Prosthetic factors include the myriad of techniques,
materials, concepts, principles, and practices which
are incorporated into the prostheses.
Although the various factors can
be divided into these four groups for academic
purposes, they are all interrelated.
42.
43. The diets of subjects with minimal bone resorption
were compared with the diets of subjects with severe
alveolar destruction.
The results indicate a positive correlation among low
calcium intake, and severe ridge resorption.
44. Emphasis was placed on the importance of considering
dietary factors in the diagnosis and treatment of
prosthodontic problems which arise from the excessive
resorption of residual ridges.
It was concluded that systemic conditions are
important in the etiology of residual ridge resorption.
The resistance of bone to mechanical stresses depends
on its physiologic state.
45. Of the many systemic influences which affect the bone
responses of patients, dietary factors may be subject to
the dentist’s control just as are factors of denture
construction.
Nutritional deficiencies and imbalances, as well
as mechanical factors, should receive
consideration in diagnosis and treatment
planning for prosthodontic patients.
