Study shows benefit of double mastectomy in women with BRCA-related breast cancer

Women with BRCA-related breast cancer who have a double mastectomy are nearly 50 per cent less likely to die of breast cancer within 20 years of diagnosis compared to women who have a single mastectomy, according to a new study led by Women's College Hospital's Kelly Metcalfe.

Novel compound appears to protect mice against movement problems associated with PD

Scientists report that they have developed a novel compound that appears to protect mice against developing movement problems associated with Parkinson's disease (PD). The research, which could one day in the future translate into a therapy that could halt the progression of PD and thereby prevent the symptoms of the disease, appears in ACS' Journal of Medicinal Chemistry.

Far-reaching neurons connect amygdala with fear response center to control behavior

Fear is primal. In the wild, it serves as a protective mechanism, allowing animals to avoid predators or other perceived threats. For humans, fear is much more complex. A normal amount keeps us safe from danger. But in extreme cases, like post-traumatic stress disorder (PTSD), too much fear can prevent people from living healthy, productive lives.

Scientists explain why women with dense breast tissue at greater risk of developing breast cancer

Scientists from The University of Manchester working with IBM Research have identified a key biological mechanism that for the first time explains why women with dense breast tissue are at greater risk of developing breast cancer.

Chronic stress generates long-term changes in brain that lead to mental problems

University of California, Berkeley, researchers have shown that chronic stress generates long-term changes in the brain that may explain why people suffering chronic stress are prone to mental problems such as anxiety and mood disorders later in life.

Researchers discover highly accurate, noninvasive test to identify benign pancreatic cysts

Researchers at the Indiana University School of Medicine have discovered a highly accurate, noninvasive test to identify benign pancreatic cysts, which could spare patients years of nerve-racking trips to the doctor or potentially dangerous surgery.

Researchers examine how evolution relates to health

February 12 marks the birth of the 19th century naturalist Charles Darwin, who launched the scientific study of evolution. While Darwin's theory laid the groundwork, ongoing studies have deepened our understanding of evolution, including how it relates to health. Research funded by the National Institutes of Health has helped answer many questions about evolution, health and medicine. Here's a sampling.

Researchers investigate sex differences in brain structure

Reviewing over 20 years of neuroscience research into sex differences in brain structure, a Cambridge University team has conducted the first meta-analysis of the evidence, published this week in the prestigious journal Neuroscience and Biobehavioral Reviews.

New video tracking system could help select most viable sperm

To improve their chances of success, in vitro fertilization (IVF) clinics need to assess the viability of the sperm they use. Now doctors may soon have a new technique to help them sort the good sperm cells from the less viable ones: a tracking system, developed by a team of researchers from four European institutions, that takes 3-D movies of living sperm.

Biologists demonstrate highly effective method for delivering HIV-fighting antibodies

In 2011, biologists at the California Institute of Technology (Caltech) demonstrated a highly effective method for delivering HIV-fighting antibodies to mice-a treatment that protected the mice from infection by a laboratory strain of HIV delivered intravenously.

Protein plays previously unknown role in acute myeloid leukemia development

There are potentially effective treatments for acute myeloid leukemia (AML), but they only work in 20 to 40 percent of cases. In a paper published today in Leukemia, a Nature journal, a UT Health Science Center researcher has pinpointed a protein that could play a key, previously unknown role in the development of pediatric AML - promising new information in the quest to treat and cure childhood leukemias.

Researchers demonstrate new approach to treating muscular dystrophy

Researchers at Washington University School of Medicine in St. Louis have demonstrated a new approach to treating muscular dystrophy. Mice with a form of this muscle-weakening disease showed improved strength and heart function when treated with nanoparticles loaded with rapamycin, an immunosuppressive drug recently found to improve recycling of cellular waste.

Red wine and dark chocolate taste great and have heart-healthy components

Forget the oysters and the champagne this Valentine's Day. If you want to keep your true love's heart beating strong, the real foods of love are dark chocolate and red wine, said Loyola University Health System preventive heart specialist Sara Sirna, MD.

New approach for reducing levels of toxic protein fragments associated with Huntington's disease

An innovative therapeutic strategy for reducing the levels of toxic protein fragments associated with Huntington's disease uses a new approach called exon skipping to remove the disease-causing component of the essential protein, huntingtin.

Combination of SYK and FLT3 enzymes promotes progression of acute myelogenous leukemia

Reinforcing the need to look beyond genomic alterations to understand the complexity of cancer, researchers from Dana-Farber/Boston Children's Cancer and Blood Disorders Center report that a normal enzyme called SYK pairs with FLT3, the most commonly mutated enzyme found in acute myelogenous leukemia (AML), to promote progression of the disease.

Study findings suggest potential targets for treating HCV

The hepatitis C virus (HCV) has a previously unrecognized tactic to outwit antiviral responses and sustain a long-term infection. It also turns out that some people are genetically equipped with a strong countermeasure to the virus' attempt to weaken the attack on it.
