Scientists say DHA-rich fish oil enhances B cell activity

Fish oil rich in DHA and EPA is widely believed to help prevent disease by reducing inflammation, but until now, scientists were not entirely sure about its immune enhancing effects. A new report appearing in the April 2013 issue of the Journal of Leukocyte Biology, helps provide clarity on this by showing that DHA-rich fish oil enhances B cell activity, a white blood cell, challenging the notion that fish oil is only immunosuppressive.

Minocycline can help reduce hemorrhagic stroke damage

A new study will help determine if an antibiotic is a partial antidote for the poisonous effect blood has on the brain following a hemorrhagic stroke, researchers say.

Researchers identify link between immune response and blood clotting

Rice University researchers have found an unexpected link between a protein that triggers the formation of blood clots and other proteins that are essential for the body's immune system.

Living cells and cell fragments move in response to electric fields, scientists find

Like tiny crawling compass needles, whole living cells and cell fragments orient and move in response to electric fields - but in opposite directions, scientists at the University of California, Davis, have found. Their results, published April 8 in the journal Current Biology, could ultimately lead to new ways to heal wounds and deliver stem cell therapies.

Study: Hormone-therapy-related breast cancer cells can be attacked by cancer therapies

More than 100 women per day die from breast cancer in the United States. The odds of developing breast cancer increase for women taking hormone replacement therapy to avoid the effects of menopause.

Exosomes can transfer membrane proteins, study reveals

Important new research from UMass Medical School demonstrates how exosomes shuttle proteins from neurons to muscle cells where they take part in critical signaling mechanisms, an exciting discovery that means these tiny vehicles could one day be loaded with therapeutic agents, such as RNA interference, and directly target disease-carrying cells.

Study links genetic variation, wheezing illness to childhood asthma risk

About 90 percent of children with two copies of a common genetic variation and who wheezed when they caught a cold early in life went on to develop asthma by age 6, according to a study to be published March 28 by the New England Journal of Medicine.

Scientists discover new mechanism that regulates replication of insulin-producing beta cells in pancreas

Bringing scientists a step closer to new treatments for diabetes, researchers at the University of Pittsburgh School of Medicine and The Mount Sinai Medical Center have discovered a novel mechanism that regulates the replication of insulin-producing beta cells in the pancreas.

A new strategy to prevent herpes virus infections

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered a novel strategy for preventing infections due to the highly common herpes simplex viruses, the microbes responsible for causing genital herpes (herpes simplex virus 2) and cold sores (herpes simplex virus 1).

Study shows why certain drugs that interact with serotonin receptors have harmful effects

A team including scientists from The Scripps Research Institute (TSRI), the University of North Carolina at Chapel Hill and the Chinese Academy of Sciences has determined and analyzed the high-resolution atomic structures of two kinds of human serotonin receptor.

Researchers expand hematopoietic stem cells for bone marrow transplantation

More than 50,000 stem cell transplants are performed each year worldwide. A research team led by Weill Cornell Medical College investigators may have solved a major issue of expanding adult hematopoietic stem cells (HSCs) outside the human body for clinical use in bone marrow transplantation -- a critical step towards producing a large supply of blood stem cells needed to restore a healthy blood system.

MU researchers redefine key regulatory process in defective protein responsible for cystic fibrosis

A little more than a year after the FDA approved Kalydeco (Vx-770), the first drug of its kind to treat the underlying cause of cystic fibrosis, University of Missouri researchers believe they have found exactly how this drug works and how to improve its effectiveness in the future.

Blocked bile ducts can be effectively treated with metal stents

A multi-center analysis, led by Weill Cornell Medical College and published in the Journal of Clinical Gastroenterology, shows the use of temporary "fully covered self-expanding metal stents" (FCSEMS) can effectively fix a painful and potentially life-threatening benign biliary stricture -- a severely blocked or narrowed bile duct.

Novel modification of structural protein implicated

Studying a protein that gives structure to the nucleus of cells, Johns Hopkins researchers stumbled upon mutations associated with familial partial lipodystrophy, a rare disease that disrupts normal patterns of fat distribution throughout the body.

Eritoran drug does not reduce risk of death in patients with severe sepsis

Administration of the drug eritoran to patients with severe sepsis and septic shock failed to demonstrate a significant effect on reducing all-cause 28-day mortality or 1-year mortality, compared with placebo, according to a study in the March 20 issue of JAMA.

University of Pittsburgh researchers receive NIH grant to develop wearable artificial lung

Each year, nearly 350,000 Americans die of some form of lung disease, with another 150,000 patients needing short- and long-term care. Unfortunately, current breathing-support technologies are cumbersome, often requiring patients to be bedridden and sedated.
