In this paper ,the researchers point out that stomach hormone turns hungry people into junkies.When volunteers received a dose of a natural hunger-inducing hormone called ghrelin, their brains responded to pictures of food in the same way that addicted people's brains do to cigarettes or drugs, says Alain Dagher, a neurologist at McGill University in Montreal, Canada, who led the study.
And the study also tell us that hormone has its stimulant effects and Memory improvement,mood changes. 
Estrogen Pills Can Benefit Women with Metastatic Breast Cancer

Estrogen-receptor positive metastatic breast cancer often develops resistance to conventional therapies designed to severely lower a woman's estrogen level. A group of researchers headed by a breast cancer specialist at Washington University School of Medicine in St. Louis has found that in one-third of these cases, such tumors will respond, paradoxically, to therapy that raises a woman's estrogen level.

A team of scientists from the University of Cambridge and the University of Cukurova in Turkey have taken a major step to understanding how the brain controls the onset of puberty.
Exercise Suppresses Appetite by Affecting Appetite Hormones

A vigorous sixty-minute workout on a treadmill affects the release of two key appetite hormones, ghrelin and peptide YY, while ninety minutes of weight lifting affects the level of only ghrelin, according to a new study. Taken together, the research shows that aerobic exercise is better at suppressing appetite than non-aerobic exercise and provides a possible explanation for how that happens.
This line of research may eventually lead to more effective ways to use exercise to help control weight, according to the senior author, David J

When we are struggling to lose weight, it may seem like new fat keeps showing up again and again!
That impression is half-right. Contrary to the accepted wisdom that humans don't make new fat cells, although one's total number of fat cells may not drop below a certain level, that doesn't mean that we can't add more. Previous research has suggested that under situations where people are consuming a high number of calories, their fat cells may increase in both size and number.
Blocking brain enzyme helped mice stay slim

In this study, the researchers found that blocking a single brain enzyme helped short-circuit a key hunger signal in mice and made them eat less, lose weight and have better blood sugar control. While much more research lies ahead, they said the finding may lead to new treatments for obesity and diabetes in humans.
Non-peptide arginine-vasopressin antagonists: the vaptans
kavin submitted, created time 7 months 3 weeks (www.ncbi.nlm.nih.gov)
Arginine-vasopressin is a hormone that plays an important part in circulatory and water homoeostasis. These drugs are all effective in the treatment of euvolaemic and hypervolaemic hyponatraemia. Conivaptan is a V1a/V2 non-selective vasopressin-receptor antagonist that has been approved by the US Food and Drug Administration as an intravenous infusion for the inhospital treatment of euvolemic or hypervolemic hyponatremia.
GlaxoSmithKline's customized "red wine" drug potent in mice

LONDON (Reuters) - A drug in development that mimics a health-boosting compound found in red wine may be a powerful weapon in the fight against obesity and diabetes, researchers said on Tuesday.
A study of mice showed that the GlaxoSmithKline drug SRT1720 was about a thousand times more potent than resveratrol in activating an enzyme that helped the animals burn more energy and lower their insulin and glucose levels

Fresh evidence suggests that melatonin, a hormone that regulates the body's biological clock, is associated with type 2 diabetes.

Is there a link between sleep and type 2 diabetes? That's one implication of a new study, which has found that variants in a gene that helps regulate the body's daily rhythms increase the chance of developing the disease. The find, reported online yesterday in three papers in Nature Genetics, may suggest new ways to treat or prevent the ever more common disorder.
The body's internal clock--which controls the circadian rhythm--is kept accurate by a hormone called melatonin, whose levels fall during the day and rise at night
Amish provide clues to genetics of heart disease
piggy submitted, created time 3 weeks 6 days (sciencenow.sciencemag.org)
Downing eight-hundred-calorie milkshakes is a great way to make the fat levels in your blood skyrocket. But a small proportion of Amish in Lancaster County, Pennsylvania, are not so easily affected, researchers have found. These lucky few harbor a genetic mutation that keeps their levels of fat particles called triglycerides in check and possibly protects them from heart disease. Although their particular mutation doesn't show up very often in the general population, the gene itself could play an important role in heart disease
Control of blood vessels a possible weapon against obesity
piggy submitted, created time 21 hours 10 minutes (www.eurekalert.org)
Mice exposed to low temperatures develop more blood vessels in their adipose tissue and metabolize body fat more quickly, according to a new study from Karolinska Institutet. Scientists now hope to learn how to control blood vessel development in humans in order to combat obesity and diabetes.
The growth of fat cells and their metabolism depend on oxygen and blood-borne nutrients. A possible way to regulate the amount of body fat – in order, for instance, to combat obesity – can therefore be to affect the development of blood vessels in the adipose tissue
Mutations in the telomerase component NHP2 cause the premature aging syndrome dyskeratosis congenita
sea-maid submitted, created time 6 months 3 weeks (www.pnas.org)
Dyskeratosis congenita is a premature aging syndrome characterized by muco-cutaneous features and a range of other abnormalities, including early greying, dental loss, osteoporosis, and malignancy.
In this study, the author describe the analysis of two other proteins, NHP2 and GAR1, that together with dyskerin and NOP10 are key components of telomerase and small nucleolar ribonucleoprotein (snoRNP) complexes.
Gastric Bypass Surgery Less Helpful for Diabetics

A new study suggests that the common weight-loss surgery leads to less weight loss in patients with diabetes.
Food and Drug Administration does a double-take on bisphenol A
Darkfrog submitted, created time 2 weeks 17 hours (www.nytimes.com)
Back in August, the FDA declared that bisphenol A, a substance found in many different kinds of plastics (including baby bottles) was safe for use in products that touch human food and drink. However, this decision is now being reexamined. Bisphenol A can potentially mimic estrogen in the human body and it may be connected to heart and liver disease.
Even with the doubts over whether BPA is truly harmful, several manufacturers have begun to make and advertise baby bottles and other products as BPA-free.
