The data monitoring committee of the AVERROES study, seeing overwhelming evidence of the success of apixaban in the prevention of stroke in patients with atrial fibrillation who are unsuitable for the conventional treatment of warfarin, has recommended early termination of this study. The decision came after repeated review and careful consideration of all efficacy and safety data.

(Philadelphia)—August 31 -- The incidence of acute myocardial infarction in Italy sharply increased, particularly among young women, between the years 2001 and 2005, according to a comprehensive study funded by the Human Health Foundation (HHF), a nonprofit Italian charity for biomedical research and health education in Spoleto, Italy. The results were published in Aging Clinical Experimental Research.
A tiny marine filter-feeder, that anchors itself to the sea bed, offers new clues to scientists studying the stability of the West Antarctic Ice Sheet – a region that is thought to be vulnerable to collapse(1).
Sangart, Inc., today announced positive results from its Phase IIa proof-of-concept study of MP4OX (oxygenated pegylated hemoglobin) in severely injured trauma patients with hemorrhagic shock causing lactic acidosis. The study demonstrated that MP4OX, when given in addition to standard of care, was effective at decreasing lactate levels in treated patients. During hemorrhagic shock, inadequate perfusion of critical organs can lead to insufficient oxygenation of tissues, which can be detected by an increase in lactate levels.
Here's good news for anyone trying to lose weight or has osteoporosis: Scientists from Maine are on the trail of a weight loss drug that may revolutionize how we treat these two conditions. In a new research report published in the September 2010 print issue of The FASEB Journal, the researchers describe a newly discovered protein, called "Sprouty," responsible for regulating body fat and bone mass. Then they manipulated how much of this protein was expressed in different groups of mice specially bred to have some human genes.
For the nearly 2 million U.S. workers exposed to silica dust each year, a new discovery may help prevent or treat the development of chronic lung diseases related to this exposure. In the September 2010 issue of the Journal of Leukocyte Biology (http://www.jleukbio.org) scientists from Montana and Texas use mice to show for the first time that the part of our immune system responsible for keeping airways clean and free of contaminants (innate immunity) can cause inflammation and symptoms of disease.
In a counter-intuitive finding, new research from North Carolina State University shows that a species of shellfish widely consumed in the Pacific over the past 3,000 years has actually increased in size, despite – and possibly because of – increased human activity in the area.
LEETOWN, W. Va. — A distinct decline in horseshoe crab numbers has occurred that parallels climate change associated with the end of the last Ice Age, according to a study that used genomics to assess historical trends in population sizes.
The new research also indicates that horseshoe crabs numbers may continue to decline in the future because of predicted climate change, said Tim King, a scientist with the U.S. Geological Survey and a lead author on the new study published in Molecular Ecology.
A team led by Massachusetts General Hospital (MGH) scientists has developed a new microfluidic tool for quickly and accurately isolating neutrophils – the most abundant type of white blood cell – from small blood samples, an accomplishment that could provide information essential to better understanding the immune system's response to traumatic injury. The system, described in a Nature Medicine paper that received advance online release, also can be adapted to isolate almost any type of cell.
BUSPH study observes link between decongestant use in pregnant women and lower risk of preterm birth
A new study led by Boston University School of Public Health (BUSPH) epidemiologists has found that women who took over-the-counter decongestants during their pregnancies are less likely to give birth prematurely.
Despite medical research that indicates Vancouver's supervised injection facility, Insite, reduces needle-sharing and overdose deaths, the facility's fate is uncertain, states an analysis article in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj100032.pdf.
Canada should follow the lead of Quebec, Australia and the United Kingdom by publicly funding smoking cessation pharmacotherapies, states an editorial in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj101140.pdf.
Ames - An Iowa State University team of researchers has developed a type of hybrid proteins that can make double-strand DNA breaks at specific sites in living cells, possibly leading to better gene replacement and gene editing therapies.
The intestines have to work properly if we are to benefit from the food we eat. Digestive juices must be secreted, the food broken down into smaller components and then transported through the gut wall and onwards to muscles and organs. The lining of the gut is coated in epithelial cells, a specialised layer that produces mucous and hormones while keeping dangerous bacteria and toxins at bay. Close contact with pathogenic microbes and toxins means that the epithelial cells may mutate to form cancer.
The disruption of a structural component in heart muscle cells, which is associated with heart failure, appears to occur even before heart function starts to decline, according to a new study by researchers at the University of Iowa Roy J. and Lucille A. Carver College of Medicine.
