Published in the Oct. 3, 2008 issue of Cell, the findings--from a study in mice--point to a entirely new approach to treating and preventing obesity in humans. The discovery also offers hope for new ways to treat related disorders, such as type 2 diabetes and cardiovascular diseases--the most prevalent health problems in the United States and the rest of the developed world........ ]]> http://medicineworld.org/cancer/lead/10-2008/genes-influence-effectiveness-of-weight-loss-drug.html http://medicineworld.org/cancer/lead/10-2008/genes-influence-effectiveness-of-weight-loss-drug.html Fri, 03 Oct 2008 11:26:57 GMT Obese patients with a specific genetic make-up lose more weight when taking the weight loss drug sibutramine and undergoing behavioral treatment in comparison to those without this genetic make-up, reports a new study in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute........ ]]> http://medicineworld.org/cancer/lead/9-2008/anti-obesity-drugs-may-be-effective-against-flu.html http://medicineworld.org/cancer/lead/9-2008/anti-obesity-drugs-may-be-effective-against-flu.html Fri, 03 Oct 2008 11:26:57 GMT Viruses dramatically increase cellular metabolism, and existing anti-obesity drugs may represent a new way to block these metabolic changes and inhibit viral infection, as per a research studypublished recently in the journal Nature Biotechnology Metabolism refers to all the reactions by which living things break down nutrients to produce energy, along with those by which they rebuild broken-down nutrients into complex molecules (e.g. DNA). A significant example is the breakdown of blood sugar (e.g. glucose) and its conversation via chain reactions into adenosine triphosphate, the energy-storing currency of cellular life. As an important offshoot of that process, glucose can also be converted into fatty acids, the lipid building blocks of human hormones and cell membranes. A number of viruses, including influenza, HIV and hepatitis, use those same fatty acids to build instead their viral envelopes, outer coatings that help them penetrate human cells. Going into the study, little was known about the mechanisms through which viruses hijack metabolic building blocks from their cellular hosts, with older techniques providing a limited picture........ ]]> http://medicineworld.org/cancer/lead/9-2008/probiotic-intervention-and-lipid-profile-change.html http://medicineworld.org/cancer/lead/9-2008/probiotic-intervention-and-lipid-profile-change.html Fri, 03 Oct 2008 11:26:57 GMT The new global metabolic profiling techniques, like lipidomics as a branch of metabolomics, have made it possible to measure large numbers of different metabolites, and are currently being applied to increase our understanding of the health and disease continuum. A Finland research group investigated the effect of a three weeks intervention of a probiotic LGG intervention on serum global lipidomics profiles in healthy adults. This will be published on 28 May 2008, in the World Journal of Gastroenterology The result showed that there were decreases in the levels of lysophosphatidylcholines (LysoGPCho), sphingomyelins (SM) and several glycerophosphatidylcholines (GPCho), and increases in triacylglycerols (TAG) in the probiotic LGG group. These changes may contribute, for example, to the metabolic events behind the beneficial effects of LGG on gut barrier function seen in prior studies........ ]]> http://medicineworld.org/cancer/lead/9-2008/healthy-lifestyle-risk-of-premature-death.html http://medicineworld.org/cancer/lead/9-2008/healthy-lifestyle-risk-of-premature-death.html Fri, 03 Oct 2008 11:26:57 GMT Over half of deaths in women from chronic diseases such as cancer and heart disease could be avoided if they never smoke, keep their weight in check, take exercise and eat a healthy diet low in red meat and trans-fats, as per a research studypublished on bmj.com today. It is well known that diet, lack of physical activity, being overweight, alcohol consumption and smoking increase the risk of disease including cancer and diabetes, but little research has examined combinations of lifestyle factors in younger populations and women........ ]]> http://medicineworld.org/cancer/lead/9-2008/poor-weight-loss-after-gastric-bypass-surgery.html http://medicineworld.org/cancer/lead/9-2008/poor-weight-loss-after-gastric-bypass-surgery.html Fri, 03 Oct 2008 11:26:57 GMT Individuals with diabetes and those whose stomach pouches are larger appear less likely to successfully lose weight after gastric bypass surgery, as per a report in the recent issue of Archives of Surgery, one of the JAMA/Archives journals. Roux-en-Y gastric bypass surgery is the most common bariatric procedure in North America, as per background information in the article. During the procedure, surgeons create a smaller stomach pouch that restricts food intake and bypasses large sections of the digestive system. "When performed in high-volume centers and with a low rate of complications, gastric bypass provides sustained and meaningful weight loss, significant improvement in quality of life, improvement or resolution of obesity-associated comorbidities and extended life span," the authors write. "However, 5 percent to 15 percent of patients do not lose weight successfully, despite perceived precise surgical technique and regular follow-up"........ ]]> http://medicineworld.org/cancer/lead/9-2008/healthy-individuals-heart-disease.html http://medicineworld.org/cancer/lead/9-2008/healthy-individuals-heart-disease.html Fri, 03 Oct 2008 11:26:57 GMT In the face of a growing obesity epidemic in the United States, scientists at Wake Forest University Baptist Medical Center have new study results that indicate that how much fat a person has is not as important as where that fat is located when assessing risk for cardiovascular events and metabolic disease........ ]]> http://medicineworld.org/cancer/lead/9-2008/effect-of-obesity-related-gene.html http://medicineworld.org/cancer/lead/9-2008/effect-of-obesity-related-gene.html Fri, 03 Oct 2008 11:26:57 GMT High levels of physical activity can help to counteract a gene that normally causes people to gain weight, as per a new study by scientists at the University of Maryland School of Medicine. They analyzed gene variants and activity levels of the Old Order Amish in Lancaster County, Pa., and observed that the obesity-related FTO gene had no effect on individuals who were the most physically active........ ]]> http://medicineworld.org/cancer/lead/9-2008/higher-protein-breakfast-dieters-stay-on-track.html http://medicineworld.org/cancer/lead/9-2008/higher-protein-breakfast-dieters-stay-on-track.html Fri, 03 Oct 2008 11:26:57 GMT A new study published online today in the British Journal of Nutrition observed that timing of dietary protein intake affects feelings of fullness throughout the day.

Calcified plaque itself is not considered risky, but it is linked to the presence of less stable fatty deposits that can lead to heart attack and stroke........ ]]> http://medicineworld.org/cancer/lead/7-2008/why-eating-less-can-help-the-environment.html http://medicineworld.org/cancer/lead/7-2008/why-eating-less-can-help-the-environment.html Fri, 03 Oct 2008 11:26:57 GMT An estimated 19 percent of total energy used in the USA is taken up in the production and supply of food. Currently, this mostly comes from non-renewable energy sources which are in short supply. It is therefore of paramount importance that ways of reducing this significant fuel consumption in the US food system are found. In a paper (1) just reported in the Springer journal Human Ecology, David Pimentel and colleagues at Cornell University in New York set out many strategies which could potentially cut fossil energy fuel use in the food system by as much as 50 percent........ ]]> http://medicineworld.org/cancer/lead/7-2008/want-a-reason-to-love-your-lower-belly-fat.html http://medicineworld.org/cancer/lead/7-2008/want-a-reason-to-love-your-lower-belly-fat.html Fri, 03 Oct 2008 11:26:57 GMT Fat removed from the lower abdomen and inner thigh through liposuction was found to be an excellent source of stem cells, with higher stem cell concentrations than other areas of the body, reports a Brazilian-based study in August's Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons (ASPS). This is the first study of its kind to examine whether fat tissues from different areas of the body vary in stem cell concentration........ ]]>
