New study may show how to forestall a fatal, virus-caused immune-system meltdown

...response, avoiding the contradictory results often produced by studies that focus on only a single biochemical pathway. To better understand their results, the investigators plugged their data into the Ingenuity Systems “pathways analysis?program, which draws on a large-scale computer database of biochemi...

Researchers create artificial enzyme that mimics the body's internal engine

...ed, and that partially reduced oxygen species were produced in large amounts," Collman said. This finding led the researchers to conclude that all three active sites are essential for the proper functioning of the enzyme. According to Devaraj, the new laboratory techniques developed in this experiment may ...

Prenatal cocaine's lasting cellular effects

...sure did not alter the total amount of D1 receptor produced in the brain. However, there was a dramatic alteration in the location of the protein within the cell. "It's not where it should be," he said. D1 receptors are normally found at the cell surface, but neurons from the cocaine-exposed animals showe...

Racing neurons control whether we stop or go

...heir work found that "go" and "stop" processes are produced through a complex network of interacting neurons. If so, then how could "go" and "stop?be acting independently as required by the race model? "The model proposes that there are two processes happening in our brain, one making us ‘go?and another ma...

Twin studies reveal genetic components leading to cardiac and kidney disease

... that regulates catecholamines, chemical compounds produced in the adrenal gland that are released in reaction to stress. The study measured the plasma concentration of ET-1 in about 300 twins. The results establish and verify a previously unsuspected link between catecholamines and the endothelial system, sh...

Global 'sunscreen' has likely thinned, report NASA scientists

Xylitol reduces risk of cavities

...n February 23. Xylitol is a sugar alcohol that is produced by reduction of the sugar xylose, or wood sugar. Xylitol occurs naturally in fruits and berries, such as pears and strawberries. It is used in sugarless sweets, above all in chewing gum and lozenges. The dissertation studies what effects the subst...

Cheaper, better disease treatments expected from faster approach to developing antibodies

...ou's E-clonal antibody method, an antibody that is produced by an E. coli bacterium becomes tethered to one of its inner surfaces, or membranes. Small "errors" in the genes that produce antibodies are introduced. These changes result in slightly altered antibodies that may attach more strongly to a disease pr...

Penn study on lung-infecting bacterial enzyme suggests new approach to cystic fibrosis treatment

... School of Medicine have discovered that an enzyme produced by lung-infecting bacteria further shuts down a protein that is defective in cystic fibrosis patients. The disruption to this protein that conveys ions from lung cells to airways causes thick mucus to buildup inside the lung. The finding suggests a n...
