Scientists take 'snapshots' of enzyme action

...bly develop corrective measures. One example is a condition called trimethylaminuria, also known as "fish odor syndrome," which results from defective FMOs. Affected individuals are unable to oxygenate trimethylamine, a byproduct of protein digestion released by bacteria living in the gut. People with the dis...

Researcher studies, treats military with 'silent disease'

...d liver disease, 15 to 20 percent had cirrhosis, a condition in which scar tissue replaces healthy tissue, blocking the flow of blood through the organ and preventing it from working as it should. Cirrhosis is the twelfth leading cause of death by disease, killing about 26,000 people each year, according to Th...

A single sugar found responsible for an antibody's ability to treat inflammation

... protective abilities. "This is a very interesting condition that's set up," Ravetch says. "IgG can shift from a state that is quite inflammatory to a state that is actively anti-inflammatory by just changing a sugar." This switch occurs during a normal immune response to a foreign substance, shifting the IgG...

New research: Soy germ isoflavones reduce bone loss

...he authors of the study, "Osteoporosis is a health condition experienced by about one in three postmenopausal women, with estrogen deficiency often acting as the major cause. Hormone replacement therapy has been the most effective treatment for maintaining bone density. This treatment often has adverse side ...

Record air pollution above the Arctic

... of the research base in 1989. A specific weather condition has caused the record high air pollution. Large amounts of aerosols from eastern Europe were driven into the arctic atmosphere. Increased aerosol concentrations had already been measured at springtime of recent years. However, this „Arctic Haze" has ...

Reversing 'hibernating' heart muscle focus of UB researchers

...e and sudden death. Hibernating myocardium is a condition in which myocytes (cells in the heart's muscular tissue) shut down, but remain viable in areas that receive reduced blood flow over an extended period of time due to narrowed arteries. This creates areas of the heart that contract poorly. The new...

Fertility hope as study shows eggs survive in older ovaries

... females can no longer reproduce ?resulting in the condition we know as menopause. Professor Findlay, Dr Kerr and their colleagues have found that the total number of eggs in young and normal healthy adult female mice do not decline over time and that overall egg number is maintained for longer than previousl...

Gene linked to rare disease activates fat breakdown

...metabolism and explain why people with the genetic condition known as Chanarin-Dorfman Syndrome (CDS), who carry a mutant version of the gene, suffer from the widespread buildup of fat in tissues throughout their bodies. The group found that the gene "CGI-58" is a strong activator of one of three lipid-degrad...

Patients to benefit from novel technology revolutionizing high-speed molecular imaging

...pe simultaneously means that more than one medical condition can be searched in one go--ultimately improving the diagnosis of cancer, heart and brain diseases," explained James A. Patton, professor of radiology and physics with the department of radiology and radiological sciences at Vanderbilt University Medi...

How the US drug safety system should be changed

...lowed by postmarketing studies required before the condition is removed." Secondly, Strom maintains that the FDA needs an increased ability to regulate drugs after marketing, so that it can require post-marketing studies and labeling changes as a rule, rather than those changes being subject to negotiation be...

New angiogenesis finding may help fight cancer growth

...ia." According to the Preeclampsia Foundation, the condition affects about 200,000 American women each year. Many angiogenesis inhibitors are under study at this point, but finding a regulatory molecule that affects four separate mechanisms "makes for an interesting package," Bresnick says. The Wisconsi...

Master planners in brain may coordinate other areas' roles in cognitive tasks

...ers' theories are reinforced by akinetic mutism, a condition that occurs in patients who suffer a lesion from stroke or surgery that includes the cingulate. To varying degrees, such patients are minimally active. "If you give them a cup of coffee, they'll drink it, but they'd never ask for a cup of coffee," P...

Embryo tests give parents the choice

... embryo may not be genetically identical, due to a condition called embryo mosaicism, making it possible that the cell taken for testing may not describe the whole embryo's genetic status. Exactly how many misdiagnoses have occurred is not known, but Baruch says the survey underscores the need for better data ...

New biologic treatment for tennis elbow may replace surgery for chronic sufferers

...tients had either sought other treatment for their condition or had left the study, limiting further analysis to the PRP-treated patients. At 6 months post-treatment, the PRP-treated patients' visual analog pain scores had improved 81 percent over their baseline scores. At a 2-year evaluation, 93 percent of...

Intrinsic eye protein halts angiogenesis

"The standard paradigm has been the cornea is avascular because it has lots of anti-angiogenic molecules and it do...

Researchers discover new gene responsible for brittle bone disease
