A team led by researchers from Boston University and the National Institutes of Health has developed a new method for uncovering functional areas of the human genome by studying DNA's three-dimensional structure -- a topographical approach that extends the more familiar analysis of the sequence of the four-letter alphabet of the DNA bases. http://www.physorg.com/news156087889.html Biology Thu, 12 Mar 2009 14:46:20 EST news156087889 Men with higher vitamin C intake appear less likely to develop gout, a painful type of arthritis, according to a report in the March 9 issue of Archives of Internal Medicine. http://www.physorg.com/news155848861.html Medicine & Health Mon, 09 Mar 2009 20:21:42 EST news155848861 Despite India's economic and educational reform efforts in the last decade, the prevalence of child marriage remains high, fueling the risks of multiple unwanted pregnancies, pregnancy terminations and female sterilizations, according to a new study led by a Boston University School of Public Health (BUSPH) researcher. http://www.physorg.com/news155842614.html Medicine & Health Mon, 09 Mar 2009 18:37:20 EST news155842614 A new study provides insight into how a short burst in nitrite can exert lasting beneficial effects on the heart, protecting it from stress and assaults such as heart attacks. In this study, just published in Circulation Research, researchers at Boston University School of Medicine have demonstrated for the first time that short elevations in circulating levels of this simple anion are sufficient to have a lasting impact on the heart by modulating its oxidation status and its protein machinery. http://www.physorg.com/news155325871.html Medicine & Health Tue, 03 Mar 2009 18:05:06 EST news155325871 Researchers from Boston University found that multiple types of child maltreatment are robust risk factors for underage binge drinking based on a national multi-year study that explored the influence of social environment on the health of adolescents. http://www.physorg.com/news155314269.html Medicine & Health Tue, 03 Mar 2009 14:58:14 EST news155314269 Researchers from Boston University School of Medicine (BUSM) and Yale University School of Medicine and the University of Connecticut School of Medicine, have discovered that variants in the α-endomannosidase (MANEA) gene are associated with cocaine addiction and cocaine-induced paranoia in European American and African American populations. These findings appear in the March issue of the Archives of General Psychiatry. http://www.physorg.com/news155237270.html Medicine & Health Mon, 02 Mar 2009 17:28:34 EST news155237270 Geneticists from Boston University School of Medicine (BUSM) have reported the world's first series of cases of prenatal diagnosis for women at risk of having a child with tuberous sclerosis complex (TSC). Earlier, the Center for Human Genetics team published the first molecular prenatal diagnosis of TSC. The current study details the sequencing of the TSC genes (TSC1 and TSC2) analysed in 50 completed pregnancies. These findings appear in the March 2009 issue of the American Journal of Obstetrics and Gynecology. http://www.physorg.com/news155220572.html Medicine & Health Mon, 02 Mar 2009 12:49:58 EST news155220572 Researchers from Boston University School of Medicine (BUSM) are strongly encouraging prenatal vitamin manufacturers to use only potassium iodide and not other sources of iodine in their products. According to the researchers, potassium iodide is the best way to ensure that prenatal vitamins given to expectant mothers receive 150µg of supplemental daily iodine as recommended by the American Thyroid Association. The researchers' recommendation appears as a research letter in the February 26th issue of the New England Journal of Medicine. http://www.physorg.com/news154806918.html Medicine & Health Wed, 25 Feb 2009 17:55:45 EST news154806918 New research reveals a sophisticated brain mechanism that is critical for filtering out irrelevant signals during demanding cognitive tasks. The study, published by Cell Press in the February 26 issue of the journal Neuron, also provides some insight into how disruption of key inhibitory pathways may contribute to schizophrenia. http://www.physorg.com/news154787315.html Medicine & Health Wed, 25 Feb 2009 12:29:21 EST news154787315 People who have parents diagnosed with Alzheimer's disease or dementia perform less well on formal memory testing when compared to people of the same age whose parents never developed Alzheimer's disease or other dementia. This is true even in middle-aged persons who do not have a diagnosis of clinical stroke or dementia, according to a Boston University School of Medicine (BUSM) study. This study has been selected to be presented at a Plenary Session at the American Academy of Neurology's 61st Annual Meeting in Seattle, Wash from April 25 - May 2. http://www.physorg.com/news154264525.html Medicine & Health Thu, 19 Feb 2009 11:15:56 EST news154264525 Researchers at Boston University School of Medicine (BUSM) and Brandeis University have completed a qualitative study on the cultural environment in medical schools and how this may affect medical faculty vitality, professionalism and general productivity ultimately influencing the delivery of health care. This study appeared in the January issue of Academic Medicine. http://www.physorg.com/news152884158.html Medicine & Health Tue, 03 Feb 2009 11:50:02 EST news152884158 Researchers from Boston University School of Medicine (BUSM) and Boston Medical Center (BMC), in collaboration with other medical centers, have found that children born more than three months premature, are at three times the risk for screening positive on the modified checklist for autism in toddlers (M-CHAT). Children who screen positive on M-CHAT may be at greater risk for developing autism. These findings appear in the January issue of Journal of Pediatrics. http://www.physorg.com/news152430272.html Medicine & Health Thu, 29 Jan 2009 05:45:07 EST news152430272 (PhysOrg.com) -- In the past few decades, researchers have been investigating a variety of flying machines. Most studies have focused on improving the flying performance of standard flying mechanisms, rather than developing innovative flying mechanisms. http://www.physorg.com/news151855869.html Electronics Thu, 22 Jan 2009 14:12:11 EST news151855869 The work of Forsyth scientist Peter Jezewski, DDS, Ph.D., has revealed that duplication and diversification of protein regions ('modules') within ancient master control genes is key to the understanding of certain birth disorders. Tracing the history of these changes within the proteins coded by the Msx gene family over the past 600 million years has also provided additional evidence for the ancient origin of the human mouth. http://www.physorg.com/news151141584.html Biology Wed, 14 Jan 2009 07:46:24 EST news151141584 Researchers from Boston University School of Medicine (BUSM) have demonstrated that a recently discovered class of molecule called microRNA (miRNAs), regulate the gene expression changes in airway cells that occur with smoking and lung cancer. These findings, which appear in the on-line early edition of journal Proceedings of the National Academy of Sciences, may lead to a new, relatively non-invasive biomarker for smoking-related lung diseases. http://www.physorg.com/news151076573.html Biology Tue, 13 Jan 2009 13:42:53 EST news151076573 A Boston University School of Medicine-led research team has discovered a more efficient way to create induced Pluripotent Stem (iPS) cells, derived from mouse fibroblasts, by using a single virus vector instead of multiple viruses in the reprogramming process. The result is a powerful laboratory tool and a significant step toward the application of embryonic stem cell-like cells for clinical purposes such as the regeneration of organs damaged by inherited or degenerative diseases, including emphysema, diabetes, inflammatory bowel disease, and Alzheimer's Disease. http://www.physorg.com/news150558593.html Biology Wed, 07 Jan 2009 13:49:53 EST news150558593
