New strategies to reduce hospital-aquired infections

...ospitals throughout North America are increasingly turning their attention to water as a source of nosocomial (hospital-acquired) infection as a result of recognition of the prevalence and risks posed by waterborne pathogens. However, he noted, there is a great deal more to be done. He stated that the infec...

At the molecular level, the predator is the prey

...n predatory garter snakes and their newt quarry is turning out to be something of an illusion. At the molecular level, another battle rages. And in this second, miniature realm, it's the newt who's the aggressor. Biologists at Indiana University Bloomington, Utah State University and the University of Utah ...

While on trail of dioxin, scientists pinpoint cancer target of green tea

...on (AH) receptor, which frequently plays a role in turning on genes that are oftentimes harmful. Two years ago the team discovered that AH activity is inhibited by a chemical found in white and green teas, epigallocatechingallate or EGCG, a cousin of flavonoids found in broccoli, cabbage, grapes and red win...

Scientists identify genes responsible for 'black rot' disease in vegetables

...by spreading through the plants' vascular tissues, turning the veins in their leaves yellow and black, and causing V-shaped lesions along the margins of the leaves. All vegetables in the crucifer family, including broccoli, Brussels sprouts, cabbage, cauliflower, kale, mustard, radish, rutabaga, and turnip, ...

Some Brain Cells Change Channels

...t cells that die in Lou Gehrig's disease. Much as turning the television dial changes what comes into the living room, these brain cells are able to change what they allow in by swapping one kind of channel, or membrane opening, for another. Doing so lets the cells fine-tune their messages and adjust connec...

15 generations of untrained jocks, couch potatoes show big physiological adaptations

...gen delivery systems, the group of researchers are turning their attention to identify the various genes involved that provide the underlying signal for "why" some subjects become more athletic, while others are couch potatoes. This effort will include looking for genes and/or signaling mechanisms that prom...

Whole genome promoter mapping - Human Genome Project v2.0?

...diseases such as cancer. "Medicine is increasingly turning towards the idea of using genetic markers for diagnosis and prognosis, or determining personalized therapies, so-called pharmacogenetics, but we don't know how these genes are regulated or even related to each other. The identification of such a larg...

Gene silencing technique offers new strategy for treating, curing disease

...at directly controlling the expression of genes by turning them on or off at the DNA level could lead to drug...go on to create a protein. Current techniques for turning genes on or off focus on controlling the messenger RNA once it's already produced. But blocking all ...

Researchers make headway in mystery of migraines

...f this biochemical process, rather than completely turning it off," notes Dr. Blostein. This new understanding of how genetic mutations cause migraines takes us one step closer to the development of improved treatments, providing hope to millions of migraine sufferers. ...

Discovery of an American salamander where it shouldn't be: Korea

...ean upland as he would in his native Illinois - by turning over rocks. The plethodontids were probably overlooked, Wake said, because the newly discovered salamanders are fully terrestrial, whereas all other Asian salamanders breed in water. Korean biologists, though actively studying other salamanders and f...

Micro-molecule plays big role in birth defects

...vital role in healthy development by strategically turning off gene activity. By genetically modifying mice, scientists with the UF Genetics Institute were able to get the first-ever picture of how limbs would develop in a vertebrate without the help of microRNAs. When microRNAs were not available to turn o...

Lance Armstrong through a physiological lens: hard training boosts muscle power 8%

...period that started when Armstrong was 21 and just turning professional and ending at age 28 with his first TdF victory, also included his cancer diagnosis, surgery, chemotherapy and recovery. About eight months after chemotherapy ceased (August 1997), Armstrong was tested in Coyle's laboratory in the same m...

Several minute intermediate stage in virus-cell fusion discovered; opportunity for drug development

...he invading microbe's genetic material takes over, turning the 'host' cell into a factory to produce more copies of the virus, which then spill out to invade other cells in the body. Scientists had assumed that once a virus begins fusing with a cell's membrane, infection of the host cell was inevitable. Thu...

Researchers Create DNA-Based Sensors for Nano-Tongues and Nano-Noses

...d. "The nanotube will then pick up on that change, turning it into an electric signal that can then be reported." According to Johnson, an array of 100 sensors with different response characteristics and an appropriate pattern recognition program would be able to identify a weak known odor in the face of a ...
