A nutritionist in Nigeria says that malnutrition and iron deficiency in schoolchildren could be reduced in her country by baking up snail pie. In a research paper to be published in the International Journal of Food Safety, Nutrition and Public Health, she explains snail is not only cheaper and more readily available than beef but contains more protein. http://www.physorg.com/news177850647.html Medicine & Health Thu, 19 Nov 2009 11:10:01 EST news177850647 (PhysOrg.com) -- On average, our cells encounter a very lethal form of DNA damage 10 times a day. Lucky for us, we have the capacity to repair each and every one of them. New research now reveals exactly how two well-known proteins are involved in the process, a finding that not only helps shed light on cancer but also on how our cells maintain the integrity of our genome. http://www.physorg.com/news177322691.html Medicine & Health Fri, 13 Nov 2009 08:50:02 EST news177322691 Offspring whose mothers had been supplemented with iron-folic acid during pregnancy had dramatically reduced mortality through age 7, according to researchers at the Johns Hopkins Bloomberg School of Public Health. Researchers found that other supplement combinations, including the multiple micronutrient supplement, did not confer the same benefit. Nearly 40 percent of pregnant women worldwide are estimated to be anemic. Although there is an international policy for antenatal iron-folic acid supplementation, coverage and use of this antenatal intervention is low in many developing countries. The results are featured in the September 24 issue of the American Journal of Epidemiology. http://www.physorg.com/news175948450.html Medicine & Health Wed, 28 Oct 2009 11:50:01 EST news175948450 (PhysOrg.com) -- Yale University researchers have discovered how a protein within most cell membranes helps maintain normal cell size, a breakthrough in basic biology that has implications for a variety of diseases such as sickle cell anemia and disorders of the nervous system. http://www.physorg.com/news168788102.html Biology Thu, 06 Aug 2009 14:36:25 EST news168788102 Anemia in very elderly people aged 85 and older appears to be associated with an increased risk of death, according to a new study in CMAJ (Canadian Medical Association Journal) http://www.cmaj.ca/press/cmaj090040.pdf. http://www.physorg.com/news167919875.html Medicine & Health Mon, 27 Jul 2009 13:25:03 EST news167919875 In a proof-of-concept study, Mayo Clinic investigators have demonstrated that induced pluripotent stem (iPS) cells can be used to treat heart disease. iPS cells are stem cells converted from adult cells. In this study, the researchers reprogrammed ordinary fibroblasts, cells that contribute to scars such as those resulting from a heart attack, converting them into stem cells that fix heart damage caused by infarction. The findings appear in the current online issue of the journal Circulation. http://www.physorg.com/news167326699.html Medicine & Health Mon, 20 Jul 2009 17:10:04 EST news167326699 May 28, 2009 - A new study appearing in Congestive Heart Failure has found that the presence of anemia in patients with chronic heart failure is associated with a significantly increased risk of death. The findings also show that anemia is associated with a poorer degree of left ventricular function and a lower left ventricular ejection fraction, an objective measure of cardiac function. http://www.physorg.com/news162740319.html Medicine & Health Thu, 28 May 2009 14:39:15 EST news162740319 Four risk factors that help predict how long men may survive with metastatic prostate cancer could help doctors choose more effective treatments, according to a study led by researchers in the Duke Comprehensive Cancer Center. http://www.physorg.com/news161546633.html Medicine & Health Thu, 14 May 2009 19:04:16 EST news161546633 (PhysOrg.com) -- Biologists have long wondered why the embryonic heart begins beating so early, before the tissues actually need to be infused with blood. Two groups of researchers from Children's Hospital Boston, Brigham and Women's Hospital, and the Harvard Stem Cell Institute (HSCI) -- presenting multiple lines of evidence from zebrafish, mice and mouse embryonic stem cells -- provide an intriguing answer: A beating heart and blood flow are necessary for development of the blood system, which relies on mechanical stresses to cue its formation. http://www.physorg.com/news161439308.html Medicine & Health Wed, 13 May 2009 13:15:45 EST news161439308 The latest electronic edition of the journal Nature Genetics reports the discovery of a new gene responsible for congenital sideroblastic anemia, a rare disease, mainly characterized by the presence of ringed sideroblasts in the patients' bone marrow. http://www.physorg.com/news161026863.html Medicine & Health Fri, 08 May 2009 18:41:27 EST news161026863 In a recent issue of The Journal of Chemical Physics, published by the American Institute of Physics (AIP), a group of researchers at the University of California, Berkeley and Los Alamos National Laboratory describe the first comprehensive, molecular-level numerical study of gene therapy. Their work should help scientists design new experimental gene therapies and possibly solve some of the problems associated with this promising technique. http://www.physorg.com/news160238845.html Physics Wed, 29 Apr 2009 15:47:50 EST news160238845 Karin Cohn carries a genetic defect that led a half-dozen members of her family to develop early breast or ovarian cancer.

The findings indicate that different levels of treatment may be warranted for different patients. http://www.physorg.com/news157826654.html Medicine & Health Wed, 01 Apr 2009 17:45:05 EST news157826654 University of Cincinnati (UC) researchers have identified the specific biological mechanisms believed to lead to a rare and incurable blood disease known as Diamond Blackfan anemia (DBA). Scientists say with further investigation, their discoveries could result in drastic changes to current thinking about treatment for this disease and may lead to promising new drug therapies. http://www.physorg.com/news156348451.html Biology Sun, 15 Mar 2009 15:08:14 EST news156348451 A genetic malfunction that causes DNA instability in people with the blood disorder Fanconi anemia may put them at high risk for squamous cell carcinomas linked to human papillomavirus (HPV), according to a study posted online ahead of print by Oncogene. http://www.physorg.com/news147529555.html Medicine & Health Wed, 03 Dec 2008 12:25:55 EST news147529555 University of Utah School of Medicine researchers have developed a new tool that facilitates diagnosis of anemia related to chronic illness, as well as diseases of iron overload.
