An innovative cardiac scanner will dramatically improve the process of diagnosing heart conditions.
The portable magnetometer* is being developed at the University of Leeds, with funding from the Engineering and Physical Sciences Research Council (EPSRC) playing a key role.
A type of antibiotic that can cause hearing loss in people has been found to paradoxically protect the ears when given in extended low doses in very young mice.
The surprise finding came from researchers at Washington University School of Medicine in St. Louis who looked to see if loud noise and the antibiotic kanamycin together would produce a bigger hearing loss than either factor by itself. The results will appear in an upcoming issue of the Journal of the Association for Research in Otolaryngology and are now available online.
Using cells from mice, scientists from Iowa and Iran have discovered a new strategy for making embryonic stem cell transplants less likely to be rejected by a recipient's immune system. This strategy, described in a new research report appearing in the February 2010 print issue of The FASEB Journal (http://www.fasebj.org), involves fusing bone marrow cells to embryonic stem cells.
The research, led by Professor Panicos Demetriades of the University of Leicester, suggests that privatising government owned banks without having an effective system of regulation in place can result in a collapse of depositors' confidence in banking. This can not only undermine the ability of the banking system to finance economic growth but it can also trigger bank runs and financial instability.
Adults aged over 70 years who are classified as overweight are less likely to die over a ten year period than adults who are in the 'normal' weight range, according to a new study published today in the Journal of The American Geriatrics Society.
Geneva and Seattle—For the first time ever, studies in Mexico and Africa, published today in the New England Journal of Medicine, demonstrate a reduction in diarrheal disease deaths following rotavirus vaccine introduction in Mexico and vaccine efficacy among impoverished populations in Malawi and South Africa. Both studies underscore the importance of vaccination in achieving significant reduction of severe rotavirus infections among children in the developing world, where disease impact is greatest.
Rotavirus is the leading cause of severe, acute gastroenteritis among infants and young children throughout the world and is responsible for an estimated 527,000 deaths among children under five each year. More than 90% of childhood deaths attributed to rotavirus infection occur in developing countries. Symptoms include severe diarrhoea and vomiting, leading to loss of fluid and electrolytes which can result in dehydration, shock, and death.
Depression raises risks of advanced and severe complications from diabetes, according to a prospective study of Group Health primary-care patients in western Washington. These complications include kidney failure or blindness, the result of small vessel damage, as well as major vessel problems leading to heart attack or stroke.
Childhood cancer survivors who had brain or other central nervous system cancers, or leukemia, achieve lower-than-expected educational success compared with the general public, according to an article published online January 27 in the Journal of the National Cancer Institute.
This study was undertaken because previous studies on educational attainment among childhood cancer survivors were small, had contradictory findings, or were not population-based.
Eliminating cancer stem cells (CSCs) within a tumor could hold the key to successful treatments for ovarian cancer, which has been notoriously difficult to detect and treat, according to new findings published this week in the journal Oncogene by Yale School of Medicine researchers.
"We found that stopping the expression of two genes—Lin28 and Oct4—reduces ovarian cancer cell growth and survival," said Yingqun Huang, M.D., assistant professor in the Department of Obstetrics, Gynecology & Reproductive Sciences at Yale School of Medicine.
New research findings from a team at the Providence Heart + Lung Institute at St. Paul's Hospital and the University of British Columbia (UBC) may lead to new treatment options for abdominal aortic aneurysms (AAA) – a potentially fatal disease that currently has no pharmacological treatments.
The Centers for Disease Control and Prevention, the U.S. Food and Drug Administration and the U.S. Department of Agriculture's Food Safety and Inspection Service are investigating a multistate outbreak of Salmonella Montevideo.
Testing conducted by the Hygienic Laboratory at the University of Iowa confirmed on Monday, Jan. 25, that this strain of salmonella is linked to the outbreak that has sickened 187 people in 39 states (one case in Iowa) since July 1, 2009. No deaths have been reported. Thirty-five people have been hospitalized.
ITHACA, N.Y. – A deadly fish virus that was first discovered in the Northeast in 2005 has been found for the first time in fish from Lake Superior, report Cornell researchers. That means that the virus has now been documented in all of the Great Lakes.
The viral hemorrhagic septicemia virus (VHSV), which causes fatal anemia and hemorrhaging in many fish species, poses no threat to humans, said Paul Bowser, professor of aquatic animal medicine at Cornell's College of Veterinary Medicine.
HOUSTON - Leukemia cells, like most cancers, are addicted to glucose to generate their energy, but new research shows for the first time that these cells also rely on fatty acid metabolism to grow and to evade cell death.
Inhibiting fatty acid oxidation makes leukemia cells vulnerable to drugs that force them to commit suicide, scientists from The University of Texas M. D. Anderson Cancer Center and The University of Texas Medical School at Houston report in the January edition of the Journal of Clinical Investigation.
ITHACA, N.Y. – Figs and fig wasps have evolved to help each other out: Fig wasps lay their eggs inside the fruit where the wasp larvae can safely develop, and in return, the wasps pollinate the figs.
But what happens when a wasp lays its eggs but fails to pollinate the fig?
The trees get even by dropping those figs to the ground, killing the baby wasps inside, reports a Cornell University and Smithsonian Tropical Research Institute study published in the Proceedings of the Royal Society B (published online Jan. 13).
