Just like teenagers at a prom, proteins are tended by chaperones whose job it is to prevent unwanted interactions among immature clients. And at the molecular level, just as at the high school gym level, it's a job that usually requires a lot of energy. http://www.physorg.com/news181209738.html Biology Mon, 28 Dec 2009 15:00:08 EST news181209738 The premise that hunger makes food look more appealing is a widely held belief - just ask those who cruise grocery store aisles on an empty stomach, only to go home with a full basket and an empty wallet. http://www.physorg.com/news181194023.html Medicine & Health Mon, 28 Dec 2009 03:41:16 EST news181194023 A real possibility does exist for developing a new generation of foods that make people feel full by releasing anti-hunger aromas during chewing, scientists in the Netherlands are reporting after a review of research on that topic. Such foods would fight the global epidemic of obesity with aromas that quench hunger and prevent people from overeating. http://www.physorg.com/news180187582.html Chemistry Wed, 16 Dec 2009 12:20:04 EST news180187582 (PhysOrg.com) -- Bacteria use all sorts of cunning to trick hosts into doing their bidding. One con in their bag of tricks: the molecular mimic. In this ruse, bacteria or their agents look for all purposes like some native molecule in a cell, but then do not behave accordingly. Working with H. pylori, the bacterium responsible for gastric ulcers and cancer, researchers have revealed one way bacteria pull this off, deciphering the structure of a piece of CagA, a bacterial protein that impersonates a human protein in order to disable a key enzyme. http://www.physorg.com/news179759608.html Biology Fri, 11 Dec 2009 13:14:12 EST news179759608 A new study shows that muscle cells grown in the lab can restore an intestine's ability to squeeze shut properly. The work, performed in dogs and rats, might ultimately help treat patients with conditions such as gastric reflux and fecal incontinence. http://www.physorg.com/news179160426.html Medicine & Health Fri, 04 Dec 2009 14:47:57 EST news179160426 A drug used to treat colorectal cancer also can reverse a rare stomach disorder and should be considered first-line therapy for the disease, researchers at Vanderbilt University Medical Center report this week. http://www.physorg.com/news178382405.html Medicine & Health Wed, 25 Nov 2009 15:10:01 EST news178382405 For thousands of years it has been prescribed by traditional healers in Brazil to treat a range of ailments from headaches and stomach pain to fever and flu. http://www.physorg.com/news178315036.html Biology Tue, 24 Nov 2009 19:58:45 EST news178315036 (PhysOrg.com) -- Idaho National Laboratory biologist Frank Roberto squats on a bare, gravelly patch of ground in Yellowstone National Park's rolling backcountry.

They identified a group of substances that block a key chemical pathway that the bacteria need for survival. Their study, which could lead to new, more effective antibiotics to fight these hard-to-treat microbes, is scheduled for the October 16 issue of ACS Chemical Biology. http://www.physorg.com/news173529566.html Chemistry Wed, 30 Sep 2009 11:40:05 EST news173529566 A popular stomach-acid reducer used to prevent stress ulcers in critically ill patients needing breathing machine support increases the risk of those patients contracting pneumonia threefold, according to researchers at Wake Forest University School of Medicine. http://www.physorg.com/news172145946.html Medicine & Health Mon, 14 Sep 2009 11:30:01 EST news172145946 John Spivey has no scar -- not even a tiny one -- to show that he had recent surgery to treat chronic acid reflux. http://www.physorg.com/news171654546.html Medicine & Health Tue, 08 Sep 2009 19:00:01 EST news171654546 A 10-day-old baby born with a heart on the outside of his body is recovering in an Indian hospital after undergoing surgery to create space for the organ, reports said Friday. http://www.physorg.com/news171276336.html Medicine & Health Fri, 04 Sep 2009 10:00:02 EST news171276336 (PhysOrg.com) -- Researchers at Columbia and Rockefeller Universities have identified cells in the stomach that regulate the release of a hormone associated with appetite. The group is the first to show that these cells, which release a hormone called ghrelin, are controlled by a circadian clock that is set by mealtime patterns. The finding, published in Proceedings of the National Academy of Sciences, has implications for the treatment of obesity and is a landmark in the decades-long search for the timekeepers of hunger. http://www.physorg.com/news170688849.html Medicine & Health Fri, 28 Aug 2009 15:10:01 EST news170688849 Johns Hopkins scientists say they have figured out how bacteria that cause diarrhea may also be the culprit in some colon cancers. The investigators say that strains of the common Bacteroides fragilis (ETBF) dupe immune system cells into permitting runaway colon tissue inflammation, a precursor for malignant growth. http://www.physorg.com/news170254620.html Medicine & Health Sun, 23 Aug 2009 13:57:37 EST news170254620 (PhysOrg.com) -- New York collaborators at Columbia and Rockefeller Universities have identified cells in the stomach that time the release of a hormone that makes animals anticipate food and eat even when they are not hungry. The finding, which has implications for the treatment of obesity, marks a landmark in the decades-long search for the timekeepers of hunger. The work reveals what the stomach `tells` the brain. http://www.physorg.com/news169478118.html Medicine & Health Fri, 14 Aug 2009 14:16:11 EST news169478118 A team of researchers from Boston University, Harvard Medical School and Massachusetts Institute of Technology recently made a discovery that changes a long held paradigm about how bacteria move through soft gels. They showed that the bacterium that causes human stomach ulcers uses a clever biochemical strategy to alter the physical properties of its environment, allowing it to move and survive and further colonize its host. http://www.physorg.com/news169313255.html Chemistry Wed, 12 Aug 2009 17:00:05 EST news169313255 (PhysOrg.com) -- Eating a small lunch doesn`t necessarily mean you`ll be so hungry for dinner that you`ll eat more than usual, a new study suggests. http://www.physorg.com/news168102822.html Medicine & Health Wed, 29 Jul 2009 16:15:01 EST news168102822 Helicobacter pylori survives in the body by manipulating important immune system cells. This is shown in a thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden. The discovery may lead to new treatments against the common peptic ulcer bacterium. http://www.physorg.com/news165494291.html Medicine & Health Mon, 29 Jun 2009 11:38:39 EST news165494291 The stomach ulcer bacterium Helicobacter pylori is not transmitted through drinking water as previously thought, but rather through vomit and possibly faeces. This is shown in a thesis at the Sahlgrenska Academy, University of Gothenburg, Sweden. It is therefore possible to prevent the spread of the bacterium in developing countries through some fairly simple measures. http://www.physorg.com/news165066763.html Medicine & Health Wed, 24 Jun 2009 12:53:35 EST news165066763 Current research suggests that levels of gastrin play a key role in the development of Helicobacter-induced stomach cancer. The related report by Takaishi et al, "Gastrin is an essential cofactor for Helicobacter-associated gastric corpus carcinogenesis in C57BL/6 mice," appears in the July 2009 issue of The American Journal of Pathology. http://www.physorg.com/news165045931.html Medicine & Health Wed, 24 Jun 2009 07:05:58 EST news165045931
