Link between insomnia and obesity

A possible link between lack of sleep (insomnia) and obesity has been traced to hypocretin/orexin cells in the hypothalamus region of the brain that are easily excited and sensitive to stress, Yale School of Medicine researchers report in the April issue of Cell Metabolism.

Unconventional wiring of the brain circuits that govern sleep and waking might explain the prevalence of insomnia

Unconventional wiring of the brain circuits that govern sleep and waking might explain the prevalence of insomnia and the condition's association with obesity, according to new work published in the April issue of Cell Metabolism. Characterized by a chronic inability to fall asleep or remain sleeping, insomnia is estimated to affect one in every eight Americans.

New findings about insulin-signaling in the liver could prove useful in understanding type 2 diabetes

A collaborative effort led by The Burnham Institute's Gen-Sheng Feng has created a mouse with improved glucose tolerance and insulin activity in the liver, and generated new findings about insulin-signaling in the liver that could prove useful in understanding the pathogenesis of type 2 diabetes.

Obesity linked to diabetes

A research team headed by Professor Helena Edlund at Umeå University has achieved a breakthrough in our understanding of how obesity causes increased levels of insulin, sugar, and blood fats leading to diseases like type-2 diabetes and liver degeneration. The findings also indicate a direct way to prevent these diseases.

Protein that regulates cholesterol levels may lead to new drug targets in the fight against obesity

A protein that regulates cholesterol levels in the body also is responsible for maintaining a healthy balance between fat storage and fat burning, according to a UT Southwestern Medical Center study that may lead to new drug targets in the fight against obesity.

Researcher grows new insulin-secreting beta cells from pancreatic tissue

JDRF-funded researchers in Canada and Massachusetts have stimulated the birth of new insulin-secreting beta cells by treating human islets with a mixture of two naturally occurring peptides: epidermal growth factor (EGF) and gastrin.

Contrary to old wives tales, alcohol, does not aid lactation

A new study has found, contrary to common wisdom, that alcohol does not appear to boost the mother's production of breastmilk, and actually has a counterproductive effect.

Novel human kidney protein called renalase that regulates both heart contraction and blood pressure

Researchers at Yale School of Medicine and the VA Connecticut Healthcare System in West Haven identified a novel human kidney protein called renalase that regulates both heart contraction and blood pressure; it is a strong candidate for easily administered treatment of advanced kidney and cardiovascular disease.

Polycystic ovary syndrome increases chance of developing cardiovascular disease

Women who suffer from polycystic ovary syndrome (PCOS), one of the most common causes of female infertility in the U.S., have an increased chance of developing cardiovascular disease, according to a new study published this month in The Journal of Clinical Endocrinology & Metabolism, published by The Endocrine Society.

Alcohol consumption by women who are breast feeding reduces their milk supply

Scientific researchers have turned folklore on its head by showing that alcohol consumption by women who are breast feeding reduces their milk supply, rather than boosting it.

Metabolic side effects of antipsychotics are known, but rarely monitored

Psychiatrists are doing a “modest” job of monitoring for weight gain, diabetes and other metabolic problems that may result from use of the newer antipsychotics for schizophrenia, researchers say.

Alteration of steroid receptor genes creates fat burning muscle

The Salk Institute scientist who earlier discovered that enhancing the function of a single protein produced a mouse with an innate resistance to weight gain and the ability to run a mile without stopping has found new evidence that this protein and a related protein play central roles in the body's complex journey to obesity and offer a new and specific metabolic approach to the treatment of obesity related disease such as Syndrome X (insulin resistance, hyperlipidemia and atherosclerosis).

Effect of individualized diets on chronic disease risk

Today at the 2005 Experimental Biology Conference, the Dairy Council of California sponsored a thought-provoking symposium titled "Individualized nutrition as a tool to prevent and treat chronic disease."

$Why do black South Africans have a low hip fracture rate despite low calcium intake?$

Why do black South Africans have a low hip fracture rate despite low calcium intake?

After Nelson Mandela was released from prison February 11, 1990, all children born in the great Johannesburg area were enrolled in a 20-year longitudinal study. Officially known as “Birth to Twenty,” the study and its 3,273 youth, are colloquially referred to as “Mandela’s Children.” It’s the largest and longest running study of child and adolescent health and development in Africa, and one of the few large-scale longitudinal studies in the world.

Alcoholism reduces male heart muscle’s ability to synthesize protein

The fact that men and women react differently to alcohol consumption and addiction, health and behavior risks, disease and death is well known and accepted. Women get drunker faster on less alcohol than men, but fewer women drink either occasionally or heavily, and men are more likely to become dependent on alcohol.

Pediatric burn victims’ recovery, diabetes aided by Fenofibrate

One of the immediate serious results of sudden extreme trauma or stress, including burns and even surgery, is insulin resistance, or diabetes. As a result, healing is delayed, especially in the case of severe burns, and since the body is unable to fully use blood sugar for energy, muscle tissue is broken down as the body scavenges for other possible energy sources.

Medication that both stimulates appetite and reduces metabolic rate

Scientists at Oregon Health & Science University, in collaboration with Neurocrine Biosciences Inc., have successfully tested a research medication that both stimulates appetite and reduces metabolic rate in preclinical trials.

Avoiding risks of skin cancer from ultraviolet radiation (UVR)

Cancer Research UK has launched the SunSmart Campaign for 2005 and NRPB strongly supports the health promotion messages in the campaign.

Body fat may promote inflammation

Why does extra fat around the waist increase the risk of heart disease? A new study by Wake Forest University Baptist Medical Center researchers and colleagues suggests that inflammation may be the key.

Vegetarians who don't cook their food have abnormally low bone mass

Vegetarians who don't cook their food have abnormally low bone mass, usually a sign of osteoporosis and increased fracture risk. But a research team at Washington University School of Medicine in St. Louis also found that raw food vegetarians have other biological markers indicating their bones, although light in weight, may be healthy.
