Multiple Sclerosis, Other Autoimmune Diseases May Be Controlled By Hunger-Spiking Neurons
Date: Mar-27-2013Neurons that control hunger in the central nervous system also regulate immune cell functions, implicating eating behavior as a defense against infections and autoimmune disease development, Yale School of Medicine researchers have found in a new study published in the Proceedings of the National Academy of Sciences (PNAS). Autoimmune diseases have been on a steady rise in the United States. These illnesses develop when the body's immune system turns on itself and begins attacking its own tissues...
Newly Designed Vaccine Blocks H5 Avian Influenza In Animal Models
Date: Mar-27-2013Until now most experimental vaccines against the highly lethal H5N1 avian influenza virus have lacked effectiveness. But a new vaccine has proven highly effective against the virus when tested in both mice and ferrets. It is also effective against the H9 subtype of avian influenza. The research is published online ahead of print in the Journal of Virology. The strength of the new vaccine is that it uses attenuated, rather than "killed" virus. (Killed viruses are broken apart with chemicals or heat, and they are used because they are safer than attenuated viruses...
Link Between Higher Soy Intake Prior To Lung Cancer Diagnosis And Longer Survival In Women
Date: Mar-27-2013New results from a large observational follow-up study conducted in Shanghai, China, indicate that women with lung cancer who consumed more soy food prior to their cancer diagnosis lived longer than those who consumed less soy. The study, published in the Journal of Clinical Oncology, provides the first scientific evidence that soy intake has a favorable effect on lung cancer survival...
Researchers Decode Biology Of Blood And Iron Disorders Mapping Out Novel Future Therapies
Date: Mar-27-2013Control of Blood and Iron Disorders Affecting Patients Worldwide Centers on Regulating Iron and Blood Cell Production Two studies led by investigators at Weill Cornell Medical College shed light on the molecular biology of three blood disorders, leading to novel strategies to treat these diseases. The two new studies -- one published online March 17 by Nature Medicine and the other March 25 in the online edition of the Journal of Clinical Investigation -- propose two new treatments for beta-thalassemia, a blood disorder which affects thousands of people globally every year...
Schools Deny Migraine Children Help, UK
Date: Mar-27-2013Lack of support hits education - charity Many of Britain's 800,000 schoolchildren who suffer from migraine are seeing their education damaged through poor support for their condition. Pupils are denied access to medication amid a migraine attack, lack help to catch up on missed work when unable to join lessons, and face unfair disciplinary measures. Sanctions include monitoring their absence and detention for the failure to meet homework deadlines, as well as exclusion from school trips and activities because of low attendance records...
Vegetation In Urban Areas Acts As Crime Deterrent
Date: Mar-27-2013Contrary to convention, vegetation, when well-maintained, can lower the rates of certain types of crime, such as aggravated assault, robbery and burglary, in cities, according to a Temple University study, "Does vegetation encourage or suppress urban crime? Evidence from Philadelphia, PA," published in the journal, Landscape and Urban Planning...
Adults In India Are Substantially More Likely To Abstain From Smoking At Home If They Are Prohibited From Smoking At Work
Date: Mar-27-2013According to data from the Global Adult Tobacco Survey India, 2009/2010, 64 per cent of adults who work in smokefree environments live in a smokefree home, compared with 42 per cent of those who work where smoking is permitted. The proportion of smokefree homes is higher in states with higher proportions of smokefree workplaces...
Normal Stomach Microbes May Contribute To Disease Caused By H. pylori-Driven Ulcers
Date: Mar-27-2013Mice with different naturally occurring stomach bacteria have distinct susceptibilities to disease caused by Helicobacter pylori, the well-known cause of ulcers in humans, according to a study published online ahead of print in the journal Infection and Immunity. This is the first study to document (in mice) that the presence of certain bacteria in the stomach microbiota can prevent pathology from H. pylori...
Neurobiologists Discover New Mechanism For Long-Term Memory Formation, Identify Possible Gene Target Linked To Cognitive Disabilities
Date: Mar-27-2013UC Irvine neurobiologists have found a novel molecular mechanism that helps trigger the formation of long-term memory. The researchers believe the discovery of this mechanism adds another piece to the puzzle in the ongoing effort to uncover the mysteries of memory and, potentially, certain intellectual disabilities. In a study led by Marcelo Wood of UC Irvine's Center for the Neurobiology of Learning & Memory, the team investigated the role of this mechanism - a gene designated Baf53b - in long-term memory formation...
Protective Properties Of Influenza Vaccines Revealed By Research
Date: Mar-27-2013Collaborating scientists from Nationwide Children's Hospital, Baylor Institute for Immunology Research, and Mount Sinai School of Medicine have identified an important mechanism for stimulating protective immune responses following seasonal influenza vaccinations. The study was published in Science Translational Medicine, a journal of the American Association for the Advancement of Science (AAAS). While seasonal influenza vaccines protect 60 to 90 percent of healthy adults from "the flu," the mechanisms providing that protection are still not well understood...
