Lung cancer in women more frequently associated with EGFR mutation and ER expression

The incidence of lung cancer in women affects an estimated 516,000 women worldwide, of which 100,000 are in the United States and 70,000 in Europe. Until now, lung cancers occurring in women have been treated similarly to lung cancers in men. However, numerous studies have highlighted different characteristics of lung cancer in women.

Study shows absence of gene leads to early onset of more serious disease in MS animal model

Scientists led by a UCSF neurology researcher are reporting that they have identified the likely genetic mechanism that causes some patients with multiple sclerosis (MS) to quickly progress to a debilitating stage of the disease while other patients progress much more slowly.

Excessive intake of cola and honey can cause fainting and arrhythmia symptoms, shows study

Drinking excessive amounts of cola and eating honey made from the pollen of Rhododendrons can cause unusual syncope (fainting) and symptoms of arrhythmia, report two case studies presented as abstracts at the EHRA EUROPACE 2013 meeting, in Athens 23 to 26 June.

Researchers hope voice therapy in aging humans may help improve quality of life

A new study shows that the vocal training of older rats reduces some of the voice problems related to their aging, such as the loss of vocal intensity that accompanies changes in the muscles of the larynx. This is an animal model of a vocal pathology that many humans face as they age.

Scientist discovers key mutations that sparked hormonal revolution 500 million years ago

Evolution, it seems, sometimes jumps instead of crawls. A research team led by a University of Chicago scientist has discovered two key mutations that sparked a hormonal revolution 500 million years ago.

Study suggests new ways to maximize delivery of RNA strands

Nanoparticles that deliver short strands of RNA offer a way to treat cancer and other diseases by shutting off malfunctioning genes. Although this approach has shown some promise, scientists are still not sure exactly what happens to the nanoparticles once they get inside their target cells.

UCSF scientists explore how Dact1 mutations contribute to psychiatric disorders

Gene mutations that cause cell signaling networks to go awry during embryonic development and lead to major birth defects may also cause subtle disruptions in the brain that contribute to psychiatric disorders such as schizophrenia, autism, and bipolar disorder, according to new research by UC San Francisco scientists.

Researchers find RNA molecule that interferes with lipoprotein production, reduces hyperlipidemia

Hyperlipidemia, a condition with high levels of fats circulating in the bloodstream, is a known risk factor for various cardiovascular and metabolic disorders. While the Western diet often contributes to high levels of lipids such as cholesterol and triglycerides, over-production of the body's own lipoproteins can lead to hyperlipidemia, independent of food intake.

Study examines long-term effects on babies born to mothers with obstetric cholestasis

Babies born to mothers who suffer from a rare metabolic complication during pregnancy are programmed to be overweight, according to a study published today in the Journal of Clinical Investigation.

New study provides guidelines for stem cell transplantation in older MDS patients

A new study by an international team led by Dana-Farber Cancer Institute scientists provides the first statistically-based guidelines for determining whether a stem cell transplant is appropriate for older patients with myelodysplastic syndromes - the most common blood disorders in people over 60 years of age, and frequently a precursor for leukemia.

Research findings could lead to new potential treatment for multiple sclerosis

Myelin, the fatty coating that protects neurons in the brain and spinal cord, is destroyed in diseases such as multiple sclerosis. Researchers have been striving to determine whether oligodendrocytes, the cells that produce myelin, can be stimulated to make new myelin. Using live imaging in zebrafish to track oligodendrocytes in real time, researchers reporting in the June 24 issue of the Cell Press journal Developmental Cell discovered that individual oligodendrocytes coat neurons with myelin for only five hours after they are born. If the findings hold true in humans, they could lead to new treatment strategies for multiple sclerosis.

Researchers test modified dendritic cells in patients with melanoma

In this issue of the Journal of Clinical Investigation, researchers led by Scott Pruitt at Duke University and Merck Research Laboratories report on a human clinical trial in which modified dendritic cells, a component of the immune system, were tested in patients with melanoma.
