Scientists at the University of Bonn, Germany, have discovered a previously unknown fruit fly gene that controls the metabolism of fat. Larvae in which this gene is defective lose their entire fat reserves. Therefore the researchers called the gene 'schlank' (German for 'slim'). Mammals carry a group of genes that are structurally very similar to 'schlank'. They possibly take on a similar function in the energy metabolism. The scientists therefore have hopes in new medicines with which obesity could be fought. Their research bas been published in The EMBO Journal. http://www.physorg.com/news176376673.html Biology Mon, 02 Nov 2009 09:34:12 EST news176376673 A nutrition professor at the University of Rhode Island studying the effects of chewing sugar-free gum on weight management has found that it can help to reduce calorie intake and increase energy expenditure. http://www.physorg.com/news175871180.html Medicine & Health Tue, 27 Oct 2009 14:50:04 EST news175871180 According to new research from the Monell Center and the Mount Sinai School of Medicine, certain common herbicides and lipid-lowering fibrate drugs act in humans to block T1R3, a nutrient-sensing taste receptor also present in intestine and pancreas. http://www.physorg.com/news174309380.html Chemistry Fri, 09 Oct 2009 12:30:01 EST news174309380 Flies fed an "anti-Atkins" low protein diet live longer because their mitochondria function better. The research, done at the Buck Institute for Age Research, shows that the molecular mechanisms responsible for the lifespan extension in the flies have important implications for human aging and diseases such as obesity, diabetes and cancer. http://www.physorg.com/news173618983.html Biology Thu, 01 Oct 2009 12:50:06 EST news173618983 Best known as the oxygen-carrying component of hemoglobin, the protein that makes blood red, heme also plays a role in chemical detoxification and energy metabolism within the cell. Heme levels are tightly maintained, and with good reason: Too little heme prevents cell growth and division; excessive amounts of heme are toxic. http://www.physorg.com/news171885687.html Medicine & Health Fri, 11 Sep 2009 11:03:12 EST news171885687 Just one drink can quickly go to your head. Researchers in Heidelberg tested this well-known adage. Only six minutes after consuming an amount of alcohol equivalent to three glasses of beer or two glasses of wine, leading to a blood alcohol level of 0.05 to 0.06 percent, changes have already taken place in the brain cells, as the scientists in Heidelberg proved using magnetic resonance spectroscopy (MRS). Previously the only available data was from animal trials. The results of the study were published in the Journal of Cerebral Blood Flow and Metabolism. http://www.physorg.com/news164288991.html Medicine & Health Mon, 15 Jun 2009 13:20:01 EST news164288991 Scientists have uncovered an interesting connection between two important protein kinase signaling pathways that are associated with cancer. The research, published by Cell Press in the January 30th issue of the journal Molecular Cell, may direct new therapeutic strategies for multiple types of cancer. http://www.physorg.com/news152469880.html Medicine & Health Thu, 29 Jan 2009 16:45:08 EST news152469880 German scientist Otto H. Warburg's theory on the origin of cancer earned him the Nobel Prize in 1931, but the biochemical basis for his theory remained elusive. http://www.physorg.com/news150954448.html Medicine & Health Mon, 12 Jan 2009 03:47:28 EST news150954448 Scientists have identified an initiating molecular mechanism in sporadic Alzheimer's disease (AD). The study, published by Cell Press in the December 26th issue of the journal Neuron, provides new information about generation of damaging amyloid β (Aβ) plaques within the AD brain and underscores the importance of developing new preventative and disease-modifying therapies for AD, especially those aimed at interrupting pathological Aβ-production. http://www.physorg.com/news149344720.html Medicine & Health Wed, 24 Dec 2008 12:38:40 EST news149344720 The liver plays a pivotal role in fuel and energy metabolism. Many studies have shown that patients with liver cirrhosis have nutrient and energy metabolism imbalances, which lead to malnutrition and can seriously affect their prognosis. However, the characteristics of the fuel and energy metabolism in patients with chronic severe hepatitis are not clear. http://www.physorg.com/news141471591.html Medicine & Health Wed, 24 Sep 2008 10:39:51 EST news141471591 Scientists at the University of Sheffield have shown how bacteria could be used as a future fuel. The research, published in the journal Bioinformatics, could have significant implications for the environment and the way we produce sustainable fuels in the future. http://www.physorg.com/news137233795.html Biology Wed, 06 Aug 2008 09:29:55 EST news137233795
