ANN ARBOR, Mich. — Scientists at the University of Michigan Heath System and their collaborators have found four new DNA "hotspots" that may one day help guide new treatments for psoriasis, one of the most common autoimmune diseases in the country.

WHAT:Scientists supported by the National Institutes of Health (NIH) have determined the complete genetic blueprints for 13 different strains of Borrelia burgdorferi, the bacteria that cause Lyme disease. The achievement should lead to a better understanding of how genetic variations among strains may result in different courses of illness in people with Lyme disease, the most common tickborne disease in North America. The wealth of new genetic data will also help scientists develop improved ways to diagnose, treat and prevent Lyme disease.
Analysis of H1N1 antibody levels (seroprotection rates) after 2009 suggest that a pandemic is unlikely in 2010, although adults over age 50, particularly those with chronic conditions, should be immunized for the fall flu season, states a research paper in CMAJ (Canadian Medical Association Journal).
ANN ARBOR, Mich. — Having an egg allergy is not a reason to avoid getting the 2010-2011 flu vaccination.
According to new recommendations by the American Academy of Allergy, Asthma & Immunology website, anyone with a history of suspected egg allergy should first be evaluated by an allergist or immunologist for appropriate testing and diagnosis but can probably receive the vaccination.
An enzyme that keeps intestinal bacteria out of the bloodstream may also play an important role in maintaining the normal microbial population of the gastrointestinal system. Since the loss of beneficial bacteria that usually results from antibiotic therapy can sometimes lead to serious health problems, a treatment that maintains microbial levels could have significant benefits.
Information on proteins is critical for understanding how cells function in health and disease. But while regular proteins are easy to extract and study, it is far more difficult to gather information about membrane proteins, which are responsible for exchanging elements essential to our health, like copper, between a cell and its surrounding tissues.
There is an association between type 2 diabetes mellitus and colorectal cancer (CRC) among men, but not women, according to a new study in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute.
Oxford, UK, 18 October 2010 – Elsevier announces the publication of the 2010 European Resuscitation Council (ERC) Guidelines in the journal Resuscitation. These guidelines are based on an extensive international review of all the science supporting cardiopulmonary resuscitation (CPR), the 2010 International Consensus on CPR Science, which is also published in the current issue of Resuscitation. This year is the 50th anniversary of CPR.
Our genetic material is often compared to a book. However, it is not so much like a novel to be read in one piece, but rather like a cookbook. The cell reads only those recipes which are to be cooked at the moment. The recipes are the genes; 'reading' in the book of the cell means creating RNA copies of individual genes, which will then be translated into proteins.
Genetic variants associated with increased susceptibility to psoriasis are reported in five papers published online this week in Nature Genetics. Psoriasis is a chronic and recurrent skin disease, and one of the most prevalent autoimmune diseases, with a global prevalence of 2-3%.
One of the studies was led by the National Institute for Health Research (NIHR) comprehensive Biomedical Research Centre (BRC) at Guy's and St Thomas' and King's College London and the Wellcome Trust Centre for Human Genetics at Oxford University, and involved multiple UK institutions.
WORCESTER, Mass. – Researchers at the University of Massachusetts Medical School have uncovered new evidence suggesting that the SOD1 gene, which is implicated in 20 percent of inherited cases of amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease), also plays a part in sporadic forms of the disease. Discovery of this common pathology is described in the October 17 online edition of Nature Neuroscience.
Removing an extra two millimetres around an area of invasive breast cancer is sufficient to minimise any residual disease in 98 per cent of patients, according to research published in the November issue of IJCP, the International Journal of Clinical Practice.
Surgeons from the Department of Breast Surgery at Good Hope Hospital, Sutton Coldfield, UK, studied 303 women who had undergone breast conserving surgery at the hospital between 2002 and 2008.
A team of scientists from Singapore led by the Genome Institute of Singapore (GIS) and the Institute of Molecular and Cell Biology (IMCB), two biomedical research institutes of Singapore's Agency of Science, Technology and Research (A*STAR), have discovered the most important genes in human embryonic stem cells (hESCs), a crucial breakthrough in discovering how human stem cells work.
PALO ALTO, CA – (OCTOBER 15, 2010) – Terminal metastatic cancer – the presently untreatable cause of the great majority of all cancer deaths – has now been effectively treated in three common fatal cancers in mice, according to announced Genomic Systems, citing research published online in the Proceedings of the National Academy of Sciences (PNAS).
Bethesda, Maryland (October 14, 2010) – Many of the world's preeminent gastroenterologists will gather for the American College of Gastroenterology's (ACG) 75th Annual Scientific Meeting at the Henry B. Gonzalez Convention Center in San Antonio, Texas starting Monday October 18, 2010, to review the latest scientific advances in gastrointestinal research, treatment of digestive diseases and clinical practice management.
