Eight things you need to know about ovarian cancer

Ovarian cancer doesn't get the kind of attention breast cancer gets. It's not as common, and because survival rates are poor, it does not produce an army of survivors to raise awareness.

Mechanism identified that plays a critical role in multiple myeloma cell cycle and survival

Researchers at Emory University's Winship Cancer Institute are the first to discover a mechanism that plays a critical role in the multiple myeloma cell cycle and survival.

Women more at risk from sleep deprivation than men

New research led by researchers at Warwick Medical School at the University of Warwick reveals that women's health is much more at risk from sleep deprivation than men's.

Researchers make new discovery on pigment melanin and skin - hair color

The pigment melanin, which is responsible for skin and hair color in mammals, is produced in specialized cells called melanocytes and then distributed to other cells. But not every cell in the complex layers of skin becomes pigmented.

Some with breast cancer stop taking aromatase inhibitors because of joint and muscle pain

More than 10 percent of women with breast cancer stopped taking a commonly prescribed drug because of joint and muscle pain, according to a new study from researchers at the University of Michigan Comprehensive Cancer Center.

Racial disparities in prostate cancer, why?

African-American men face a higher risk of developing prostate cancer in their lifetime, but researchers do not fully understand why.

New method to create natural drug products

Until now, only the intricate machinery inside cells could take a mix of enzyme ingredients, blend them together and deliver a natural product with an elaborate chemical structure such as penicillin.

Immunosuppressive drugs are a double-edged sword to type 1 diabetics

Type 1 diabetes is caused when immune cells attack and destroy the insulin producing beta-cells of the pancreas.

Should doctors participate in capital punishment?

Should doctors be involved in the state-ordered administration of capital punishment?

Better communication makes for less complaints among doctors

Physicians who score poorly on patient-physician communication skills exams are far more likely to generate patient complaints to regulatory authorities, says a new study led by McGill University's Robyn Tamblyn and published in the September 5 issue of JAMA.

Young persons who view more smoking in movies are at increased risk for initiating cigarette smoking

Exposure to smoking in movies appears to be associated with adolescents' risk of becoming established smokers who have used at least 100 cigarettes in their lifetimes, according to a report in the September issue of Archives of Pediatrics & Adolescent Medicine.

Study identifies osteopontin as a key player in the body's immune response to chronic stress

Osteopontin (OPN), a protein molecule involved in many different cellular processes, plays a significant role in immune deficiency and organ atrophy following chronic physiological stress, resulting in increased susceptibility to illness.

Mice stressed in simulated weightlessness show organ atrophy

A ground-based, experimental model used to simulate astronaut weightlessness in space has provided Rutgers scientists an opportunity to study the effects of stress on immune organs.

Drug eluting stents should be used with caution in acute myocardial infarction

Drug-eluting stents are extremely effective devices to prevent restenosis following angioplasty. Yet, since last year, there is some debate and persistent uncertainty regarding the long term safety of these devices. Specifically, there is concern that some of these stents may occlude abruptly more than 1 year after placement, due to "late stent thrombosis".

First common height gene identified by researchers behind 'obesity gene' finding

Whilst we all know that tall parents are more likely to have tall children, scientists have been unable to identify any common genes that make people taller than others. Now, however, scientists have identified the first gene, known as HMGA2, a common variant of which directly influences height.

Diets double the odds a teenage girl will begin smoking

Starting to diet seems to double the odds a teenage girl will begin smoking, a University of Florida study has found. UF researchers, who analyzed the dieting and smoking practices of 8,000 adolescents, did not find the same link in boys, who were also less likely than girls to diet, according to findings released Friday in the American Journal of Health Promotion.

Genetic variant linked to human height discovered

It became clear nearly a century ago that many genes likely influence how tall a person grows, though little progress, if any, has followed in defining the myriad genes. Now an international research team brings light to this age-old question by pinpointing a genetic variant associated with human height - the first consistent genetic link to be reported.

Brain's impaired ability to sense glucose might play role in type 2 diabetes

New findings from studies in mice suggest that defects in the brain's ability to respond to glucose play a role in the development of non-insulin dependent (type 2) diabetes, and that a high-fat diet may contribute to impairing brain cells' ability to regulate glucose throughout the body.
