Team identifies successful combination drug therapies for melanoma mutations
Team identifies successful combination drug therapies for melanoma mutations
Yale Cancer Center researchers have identified several effective combinations of therapies that inhibit melanomas driven by two of the most formidable cancer genes. Some combinations include cholesterol-lowering statin drugs. The study appears in the journal Cancer Discovery. The Yale scientists were seeking to overcome the problems of resistance and partial response to single-drug cancer therapy in patients with melanoma.

Stanford experiment finds ulcer bug's weak point
Stanford experiment finds ulcer bug’s weak point
Stanford Report, December 12, 2012 SLAC's high-power X-rays have revealed a potential drug target in H. pylori , the ulcer-causing bacteria that infect half the world's population. In 1982, Australian scientists extracted bacteria from a person's stomach, grew them in a petri dish and identified them as the cause of ulcers and gastritis.

The slower you grow, the longer you live: growth rate influences lifespan
New research from the University of Glasgow suggests that lifespan is affected by the rate at which bodies grow early in life. A paper published today in the journal Proceedings of the Royal Society B outlines how manipulating growth rates in stickleback fish can extend their lifespan by nearly a third or reduce it by 15 percent.

Capturing circulating cancer cells could provide insights into how disease spreads
Capturing circulating cancer cells could provide insights into how disease spreads
ANN ARBOR-A glass plate with a nanoscale roughness could be a simple way for scientists to capture and study the circulating tumor cells that carry cancer around the body through the bloodstream. Engineering and medical researchers at the University of Michigan have devised such a set-up, which they say takes advantage of cancer cells' stronger drive to settle and bind compared with normal blood cells.

Diabetes drug may work against Alzheimer's
Diabetes drug may work against Alzheimer’s
Medical researchers at the University of Alberta have discovered that a drug intended for diabetes appears to restore memory in brain cells affected by Alzheimer's disease. Jack Jhamandas , a researcher with the Faculty of Medicine & Dentistry at the U of A, is the principal investigator with the team whose research results were recently published in the peer-reviewed publication The Journal of Neuroscience .

Mexican American toddlers lag in preliteracy skills, but not in their social skills, new study shows By Kathleen Maclay , Media Relations Mexican American preschoolers fall behind their white counterparts in terms of early language and preliteracy skills, but the social competencies between the two groups are indistinguishable, according to new research from the University of California, Berkeley, and UCLA.

Faulty gene linked to condition in infants
Researchers at King's College London have for the first time identified a defective gene at the root of Vici syndrome, a rare inherited disorder which affects infants from birth, leading to impaired development of the brain, eyes and skin, and progressive failure of the heart, skeletal muscles and the immune system.

How our nerves regulate insulin secretion
How our nerves regulate insulin secretion
The autonomic nervous system, which is the part of the nervous system beyond conscious control, plays an important role in the release of insulin from beta cells in the endocrine part of the pancreas. The process by which this occurs has been a mystery, since it is difficult to give detailed study to such an inaccessible organ.

Prostate cancer now detectable using imaging-guided biopsy, UCLA study demonstrates
Groundbreaking research by a team of UCLA physicians and engineers shows that prostate cancer — long identifiable only through painful, hit-or-miss biopsies — can be diagnosed far more easily and accurately using a new image-guided, targeted biopsy procedure. Traditionally, prostate tumors have been found through so-called blind biopsies, in which tissue samples are taken systematically from the entire prostate in the hopes of locating a piece of tumor — a technique that dates back to the 1980s.

Teen dating violence linked to long-term harmful effects
Teen dating violence linked to long-term harmful effects
Teenagers in physically or psychologically aggressive dating relationships are more than twice as likely to repeat such damaging relationships as adults and report increased substance use and suicidal feelings years later, compared with teens with healthy dating experiences, reports a new Cornell study.

Inspiration from a porcupine’s quills
Understanding the mechanisms behind quill penetration and extraction could help engineers design better medical devices. Anyone unfortunate enough to encounter a porcupine's quills knows that once they go in, they are extremely difficult to remove. Researchers at MIT and Brigham and Women's Hospital now hope to exploit the porcupine quill's unique properties to develop new types of adhesives, needles and other medical devices.

UCLA cancer scientists identify liposarcoma tumors that respond to chemotherapy
Liposarcoma, the most common type of sarcoma, is an often lethal form of cancer that develops in fat cells. It is particularly deadly, in part, because the tumors are not consistently visible with positron emission tomography (PET) scans that use a common probe called FDG and because they frequently do not respond to chemotherapy.

Research proves low fat diet is key to a slimmer figure
Cutting down on fat, without dieting, will result in a slimmer figure - according to new research co-authored by Durham University Findings published today in the British Medical Journal show that exchanging fatty foods for lower fat alternatives will help people shift around three-and-a-half pounds - without dieting.

New study sheds light on how Salmonella spreads in the body
This research provides critical insight which will hopefully lead to new medical interventions for this disease." —Dr Andrew Grant Findings of Cambridge scientists, published today in the journal PLoS Pathogens , show a new mechanism used by bacteria to spread in the body with the potential to identify targets to prevent the dissemination of the infection process.

New Strategy to Prevent or Halt Periodontal Disease
Periodontitis, a form of chronic gum disease that affects nearly half of the U.S. adult population, results when the bacterial community in the mouth becomes unbalanced, leading to inflammation and eventually bone loss. In its most severe form, which affects 8.5 percent of U.S. adults, periodontitis can impact systemic health.

Cognitive behavioural therapy can reduce depression and improve quality of life
Cognitive behavioural therapy (CBT) provided alongside drug treatment can help reduce the symptoms of depression and improve patients' quality of life, according to new research. Depression is a very common illness which has a major impact on a patient's life. In the UK between five and ten per cent of the population has the illness at any one time.

Novel protein makes muscles bigger and stronger
Novel protein makes muscles bigger and stronger
In a study in mice, Swedish and American scientists have identified a previously unknown protein that spurs muscle growth and increased power following resistance exercise - such as bodybuilding or weightlifting. The findings are presented in the journal Cell, and the scientists speculate that artificially raising the novel protein's levels might someday help prevent muscle mass loss caused by, for example, cancer, prolonged inactivity in hospital patients, and aging.

Babies get a better chance to escape a dangerous health cycle
A promising step forward in stopping an intergenerational cycle of birth complications, diabetes and obesity associated with gestational diabetes has been made by researchers at the University of Sydney. "To our knowledge, this is the first study to show that mums with carefully controlled gestational diabetes mellitus (GDM) can give birth to babies with normal levels of body fat," said Cheryl Au, who recently completed her Bachelor of Medicine/Surgery at Sydney Medical School and is lead author of the study published in Diabetes Care today.
