Two-drug combination may alleviate radiation sickness in people

A combination of two drugs may alleviate radiation sickness in people who have been exposed to high levels of radiation, even when the therapy is given a day after the exposure occurred, according to a study led by scientists from Dana-Farber Cancer Institute and Children's Hospital Boston.

Dendritic cells play a novel protective role in pancreas

NYU Langone Medical Center researchers have discovered the novel protective role dendritic cells play in the pancreas. The new study, published in the November issue of journal Gastroenterology, shows dendritic cells can safeguard the pancreas against acute pancreatitis, a sudden dangerous swelling and inflammation of the pancreas gland.

Arginine may reactivate T-cells in patients with glioblastoma

In many cases, tumors suppress a patient's immune system in a way that keeps the cancer safe from immune system attack. This is particularly true for patients with glioblastoma, a primary brain tumor that carries a prognosis of only 12-15 months survival after diagnosis.

Researchers discover molecular sensor that detects wound-induced hydrogen peroxide

Hydrogen peroxide isn't just that bottled colorless liquid in the back of the medicine cabinet that's used occasionally for cleaning scraped knees and cut fingers. It's also a natural chemical in the body that rallies at wound sites, jump-starting immune cells into a series of events. A burst of hydrogen peroxide causes neutrophils, the immune system's first responders, to rush to the wound to fight microorganisms, remove damaged tissue and then start the inflammation process.

EUSA Pharma receives FDA approval for Erwinaze to treat ALL

The U.S. Food and Drug Administration today approved Erwinaze to treat patients with acute lymphoblastic leukemia (ALL), who have developed an allergy (hypersensitivity) to E. coli derived asparaginase and pegaspargase chemotherapy drugs used to treat ALL.

Dendrimers can capture circulating tumor cells in blood by biomimicry

The removal of rare tumor cells circulating in the blood might be possible with the use of biomolecules bound to dendrimers, highly branched synthetic polymers, which could efficiently sift and capture the diseased cells, according to new research at the University of Illinois at Chicago.

Researchers identify hepcidin hormone as potential target for atherosclerosis

Researchers at Emory University School of Medicine have identified hepcidin, a hormone that regulates iron levels in the body, as a potential target for treating atherosclerosis.

CIHR honors University of Calgary scientist with prestigious award for medical research

University of Calgary researcher Paul Kubes, PhD, is the recipient of one of Canada's top awards for medical research. An internationally-recognized scientist specializing in visualizing the mammalian immune system, Kubes will accept the 2011 Canada's Health Researcher of the Year award from the Canadian Institutes of Health Research (CIHR) at a ceremony in Ottawa this evening.

New 2-DG-ABT combination cancer therapy triggers apoptosis

Researchers at the University of California, San Diego School of Medicine and Kyushu University Medical School say a novel combination of a specific sugar molecule with a pair of cell-killing drugs prompts a wide variety of cancer cell types to kill themselves, a process called apoptosis or programmed cell death.

Researchers identify potential marker for leukemic relapse

The development of simple tests to predict a leukemic relapse in young patients is a step closer thanks to researchers from the Sainte-Justine University Hospital Research Center and the University of Montreal. Approximately 20 percent of young leukemia patients who are treated with stem cells derived from umbilical cord blood will experience leukemic relapse.

Leading alcohol researchers to discuss latest genetic findings at Loyola meeting

Leading alcohol researchers from the United States and Canada will discuss their latest findings at an all-day meeting Nov. 18 at Loyola University Chicago Stritch School of Medicine.

Atherosclerotic plaques spread downstream in coronary arteries

In human coronary arteries, atherosclerotic plaques tend to spread downstream because of the changes in blood flow patterns the plaque causes, researchers have found.

New paper shows how platelets help promote cancer metastasis

About 90 percent of cancer deaths are caused by secondary tumors, known as metastases, which spread from the original tumor site. To become mobile and break free from the original tumor, cancer cells need help from other cells in their environment. Many cells have been implicated in this process, including immune system cells and cells that form connective tissue. Another collaborator in metastasis is platelets, the blood cells whose normal function is to promote blood clotting.

Classical DCs associated with protection against atherosclerosis

Atherosclerosis, commonly referred to as "hardening of the arteries," is a major risk factor for heart attack and stroke. The cause of atherosclerosis is not well understood but, for some time, chronic inflammatory immune responses have been implicated in driving disease pathology. Now, a new study, published online on November 10th by Cell Press from the journal Immunity, identifies a type of immune cell that is not associated with promoting disease, but with protection against atherosclerosis.

People with recurrent depression, chronic stress have shorter telomeres in WBCs

People with recurrent depressions or those exposed to chronic stress exhibits shorter telomeres in white blood cells. This is shown by a research team at Umeå University in a coming issue of Biological Psychiatry.

Study provides blueprint for design of new HIV drugs

Scientists have moved a step closer to understanding how one of our body's own proteins helps stop the human immunodeficiency virus (HIV-1) in its tracks.
