Inhibiting Notch signalling makes hormone-receptor positive cells dependent on estrogen

Within many hormone-receptor positive breast cancers lives a subpopulation of receptor-negative cells - knock down the hormone-receptor positive cells with anti-estrogen drugs and you may inadvertently promote tumor takeover by more dangerous, receptor-negative cells.

PSTC, FNIH Biomarkers Consortium launch clinical study to improve detection of kidney injury

The Foundation for the National Institutes of Health (FNIH) Biomarkers Consortium announced today the launch of a two-year clinical study aiming to advance the acceptance of new biomarkers designed to detect drug-induced kidney injury in clinical trials.

Study supports existence of metastable frequency-band-dependent scaffold of brain connectivity

Over the past two decades, the increased ability to analyze relationships among neural structures has provided novel insights into brain function. Most network approaches, how-ever, focus on static representations of the brain's physical or statistical connectivity.

Solid organ transplant may increase risk of cancer

Patients who have received a solid organ transplant, such as kidney, liver, heart or lung, have an overall cancer risk that is double that of the general population, with an increased risk for many different types of malignancies, according to a study in the November 2 issue of JAMA.

TERE1 gene mutation also contributes to invasive bladder cancer

Research conducted by Dr. Jayne S. Weiss, Professor and Chair of Ophthalmology at LSU Health Sciences Center New Orleans, and colleagues has found that a defect in a gene involved in a rare disease of the cornea also contributes to the progression of invasive bladder cancer.

NIH-funded project to discover biomarkers for type 2 diabetes

Arizona State University will lead a four-year, $5 million expanded initiative sponsored by the National Institutes of Health to discover proteins, or biomarkers, to help predict cardiovascular disease and to assess potential new treatments in people with type 2 diabetes.

Age is no longer a barrier to allogeneic stem cell transplantation

Age alone no longer should be considered a defining factor when determining whether an older patient with blood cancer is a candidate for stem cell transplantation. That's the conclusion of the first study summarizing long-term outcomes from a series of prospective clinical trials of patients age 60 and over who were treated with the mini-transplant, a "kinder, gentler" form of allogeneic (donor cell) stem cell transplantation developed at Fred Hutchinson Cancer Research Center.

Health risk associated with harmful substances in food may be underestimated

Mice are often used to test whether substances in food are harmful to humans. This requires that mice and humans metabolise substances in the same way. Humans have certain enzymes in more parts of the body than mice. The health risk associated with harmful substances in food may therefore be underestimated.

Researchers identify small-molecule drug candidates for many metabolic conditions

A new discovery by Californian scientists may lead to a pharmaceutical breakthrough for a wide range of illnesses that involve the hydration of cells that line the inner surfaces of our body's organs and tissues. In a new report appearing in the FASEB Journal, the researchers describe how they used high-throughput screening to identify small-molecule drug candidates which help cells bypass defective channels that normally move salt and water through cell membranes.

Obama takes action to address drug shortages

President Barack Obama issued an executive order Monday directing the Food and Drug Administration to, among other steps, speed up reviews of manufacturers' applications to begin or alter production of a drug in potentially short supply.

ADHD medications do not increase risk of heart attack in children, young adults

Attention Deficit Hyperactivity Disorder (ADHD) medications do not increase the risk for heart disease or heart attack in children and young adults, according to a Vanderbilt study of 1.2 million patients taking drugs including Ritalin, Adderall, Concerta and Strattera between 1998 and 2005.

No link between anti-clotting drugs and increased risk of bleeding in GI procedure

Patients with recent use of aspirin, nonsteroidal anti-inflammatory drugs (NSAIDS), or anti-clotting drugs such as clopidogreal (Plavix) do not appear to have an increased risk of bleeding during or after removal of precancerous lesions in the digestive tract, according to results of a Mayo Clinic study.

Targeted antibiotic safe and effective for irritable bowel syndrome

Among the most commonly used treatments for irritable bowel syndrome - which affects as many as 20 percent of the United States population - a targeted antibiotic was shown to be the safest in a new study by Cedars-Sinai researchers, based on an analysis of 26 large-scale clinical trials.

Nurse scientist recognized as AACN's 2012 Distinguished Research Lecturer

The American Association of Critical-Care Nurses (AACN) recently selected Martha A.Q. Curley, RN, PhD, FAAN, as its 2012 Distinguished Research Lecturer.

Protective response to starvation may promote heart failure

A protective response to starvation may promote heart failure, according to a study just published in Cell Metabolism. Two proteins that team up to conserve energy when food is scarce also limit energy production in the heart—a situation that can prove fatal when the heart is stressed and in need of an energy boost.

First study to show how H. pylori toxin can spur apoptosis

Researchers report they have figured out how the cancer-causing bacterium Helicobacter pylori attacks a cell's energy infrastructure, sparking a series of events in the cell that ultimately lead it to self-destruct.

First orthotics study to use multi-segment foot model

It's one of those mysteries that has baffled runners and running doctors for decades: Why do orthotics work? Orthotics are commonly prescribed for painful conditions like plantar fasciitis, and, anecdotally, people swear by them, however scientists aren't exactly sure how they work. A recent study by University of Calgary Faculty of Kinesiology researcher Reed Ferber, PhD, published in the Journal of Foot and Ankle Research, suggests that to this point, scientists have been measuring the wrong thing.

Active partnership between patient and healthcare professionals can reduce hospital stay

Healthcare that implements a person-centred approach not only make care more efficient, but also yields more satisfied patients. A study carried out at the Sahlgrenska Academy at the University of Gothenburg, Sweden, shows that if there is an active partnership between the patient and healthcare professionals, the patient's hospital stay can be reduced by one-third.

Scientists discover additional Alzheimer's proteins in the tangles

Scientists from the National Institutes of Health in the United States have made an important discovery that should forever change the scope and direction of Alzheimer's research. Specifically, they have discovered that the protein tangles which are a hallmark of the disease involve at least three different proteins rather than just one.

Ocrelizumab drug holds promise for multiple sclerosis

An experimental drug called Ocrelizumab has shown promise in a Phase 2 clinical trial involving 220 people with multiple sclerosis (MS), an often debilitating, chronic autoimmune disease that affects an increasing number of people in North America.
