Sperm enzyme is essential for male fertility, study shows

...r structures known as mitochondria were thought to provide a substantial portion of the ATP needed for sperm motility. In contrast, Dr. Deborah A. O'Brien, associate professor of cell and developmental biology at UNC's School of Medicine, and her colleagues found that sperm motility and ATP production depend...

UCSD discovery opens new avenues for design of anti-tumor medications

...as shown that tumors, which need a blood supply to provide oxygen and nutrients, release chemical signals that summon the blood vessels to grow toward them. However, these latest findings show that the blood vessels themselves are actively responding to oxygen levels, not just to the signals sent by the t...

Computer models to simulate hypothetical outbreak of avian flu

...Ph.D., NIGMS director. "This modeling project will provide a tool that policymakers, public health workers and researchers can use to test intervention strategies should such an outbreak emerge." The flu project is part of a national effort, called the Models of Infectious Disease Agent Study (MIDAS), to dev...

Community living causes bacteria to diversify

...otics. The new findings suggest biofilm growth may provide another key advantage. Using a laboratory model, the UI team found that when biofilm communities were established using a small number of identical bacteria, a remarkable degree of diversity rapidly developed in the population. "After only a few days...

Aging affects susceptibility to type 2 diabetes

... glucose metabolism is under genetic control could provide an explanation by which an environmental trigger like aging modifies genetic susceptibility to type 2 diabetes. In an accompanying commentary, Alan R. Shuldiner and John C. McLenithan from the University of Maryland School of Medicine discuss thes...

Rare immunodeficiency provides new insight into immune system function

... research studies investigating this rare disorder provide critical new information about the regulation of T helper cell cytokine secretion, a process that is absolutely critical for appropriate immune responses to infectious agents. The research is published in the November issue of Immunity. XLP is a rare...

Building a tree of life needs less 'wood'

...g related organisms on the same branch. Such trees provide an organizing framework for biology. They can be used for predicting the properties of poorly known species and are powerful tools for tasks such as drug discovery, said Michael Sanderson, professor of evolution and ecology at UC Davis and senior aut...

...systematic and controlled manner. In this paper we provide an explicit chaotic representation for the Cox--Ingersoll--Ross model, arguably the most well known model for positive interest rates. We do so by using techniques from infinite dimensional Gaussian integration inspired by quantum field theory. We th...

Study identifies molecular complex vital to creation of miRNAs

... neuronal development. Might miRNA activity, then, provide a new window on schizophrenia, at least in DiGeorge syndrome patients, but perhaps also more globally? "It would certainly be possible to look in schizophrenic populations for mutations in the DGCR8 gene," says Shiekhattar. "If those mutations were f...

A 'repulsive' protein guides blood vessel development

...ural development. The researchers said the studies provide more evidence that there is communication between developing nerves and blood vessels. Understanding how those networks communicate with each other could help researchers devise methods to prevent blood vessel growth in tumors selectively an approac...

Researchers discover defense mechanisms in some plants believed bred out by humans
