(PhysOrg.com) -- A University of Colorado at Boulder team has developed the first atlas of bacterial diversity across the human body, charting wide variations in microbe populations that live in different regions of the human body and which aid us in physiological functions that contribute to our health. http://www.physorg.com/news176655930.html Chemistry Thu, 05 Nov 2009 16:10:01 EST news176655930 Melatonin, a natural hormone segregated by the own human body, is an excellent sleep regulator expected to replace somniferous, which are much more aggressive, to correct the sleep/wakefulness pace when human biological clock becomes altered. http://www.physorg.com/news176645582.html Medicine & Health Thu, 05 Nov 2009 12:18:56 EST news176645582 (PhysOrg.com) -- The mechanism used by 'Natural Killer' immune cells in the human body to distinguish between diseased cells, which they are meant to destroy, and normal cells, which they are meant to leave alone, is revealed in new detail in research published today in PLoS Biology. http://www.physorg.com/news167989314.html Medicine & Health Tue, 28 Jul 2009 09:30:01 EST news167989314 (PhysOrg.com) -- Researchers at North Carolina State University have found that intrauterine growth restriction (IUGR), which results in low birth weight and long-term deleterious health effects in cloned swine, is linked to a type of gene - known as an imprinted gene - found only in placental mammals. Imprinted genes play an important role in the normal fetal development of all mammals, and this study could have future implications for the study of IUGR in humans. http://www.physorg.com/news167320132.html Biology Mon, 20 Jul 2009 15:00:06 EST news167320132 A team of scientists from the University of Copenhagen and the Max Planck Institute in Germany, has identified no less than 3,600 molecular switches in the human body. These switches, which regulate protein functions, may prove to be a crucial factor in human aging and the onset and treatment of diseases such as cancer, Alzheimer's disease and Parkinson's disease. The results of the team's work have been published in the current edition of the journal Science. http://www.physorg.com/news167040884.html Medicine & Health Fri, 17 Jul 2009 09:15:53 EST news167040884 Everyone sweats to some degree during exercise or other exerting activities. But for some people, profuse sweating is a constant that can quickly impact quality-of-life, according to University of Cincinnati (UC) experts. http://www.physorg.com/news166981046.html Medicine & Health Thu, 16 Jul 2009 16:37:55 EST news166981046 Wake Forest University scientists have developed a new research tool in the pursuit of heart medications based on the compound nitroxyl by identifying unique chemical markers for its presence in biological systems. http://www.physorg.com/news166081501.html Chemistry Mon, 06 Jul 2009 07:20:01 EST news166081501 (PhysOrg.com) -- A signal molecule made by the human body that triggers the immune system into action may be important in rheumatoid arthritis, according to new research published today in Nature Medicine. The authors of the study, from Imperial College London, say that if scientists could block this signal, it may be possible to develop more effective arthritis treatments. http://www.physorg.com/news165418357.html Medicine & Health Sun, 28 Jun 2009 14:35:10 EST news165418357 New combinations of agents based on the oldest synthetic malaria drug, the methylene blue stain, can curb the spread of malaria parasites and make a significant contribution to the long-term eradication called for by the international "Roll Back Malaria Initiative." In a study on 160 children with malaria in Burkina Faso, specialists in tropical medicine from the Heidelberg University Hospital have shown that in combination with newer malaria drugs, methylene blue prevents the malaria pathogen in infected persons from being re-ingested by mosquitoes and then transmitted to others and is thus twice as effective as the standard therapy. The results of the study were published in May 2009 in the online journal PLoS One. http://www.physorg.com/news162034412.html Medicine & Health Wed, 20 May 2009 10:33:57 EST news162034412 (PhysOrg.com) -- Protein p53 protects the body against cancer and is knocked out in many cancer tumours. Researchers at Karolinska Institutet have identified two molecules that can restore p53's cancer-killing properties. New results are now presented on the two substances, one of which will undergo clinical tests later this year. http://www.physorg.com/news161360881.html Medicine & Health Tue, 12 May 2009 15:28:56 EST news161360881 Researchers at the Hebrew University of Jerusalem have discovered a method to potentially eliminate the tumor-risk factor in utilizing human embryonic stem cells. http://www.physorg.com/news160816468.html Medicine & Health Wed, 06 May 2009 08:17:09 EST news160816468 In the comics, the Phantom is a masked crimefighter who protected the innocent from pirates, hijackers and other evildoers. While not as dashing or exciting as its costumed namesake, this electromagnetic phantom -- a carbon and polymer mixture that simulates the human body -- is being readied by the National Institute of Standards and Technology for its upcoming role as a different kind of protector. The NIST phantom serves as a mannequin in a standardized performance test for walk-through metal detectors or WTMDs such as those used at airports. http://www.physorg.com/news149276153.html Physics Tue, 23 Dec 2008 17:35:53 EST news149276153 You really can learn a lot from a dummy. For decades, automakers have been crashing test dummies to gain insight to how various auto safety systems protect - or fail to protect - people during car accidents. But those dummies are made of plastic and steel, not tissue and bone. They can teach only so much. http://www.physorg.com/news148236960.html Technology Thu, 11 Dec 2008 16:56:00 EST news148236960 A Brazilian palm berry, popular health food though little research has been done on it, now may have its purported benefits better understood. In the first research involving people, the acai (ah-sigh-EE) berry has proven its ability to be absorbed in the human body when consumed both as juice and pulp. That finding, by a team of Texas AgriLife Research scientists, was published in a recent issue of the Journal of Agricultural and Food Chemistry. http://www.physorg.com/news142519153.html Medicine & Health Mon, 06 Oct 2008 13:39:13 EST news142519153
