Cells re-energize to come back from the brink of death

... to supply the cell with energy, but also hold the keys to the cells’ life and death. The process by which the membranes develop holes—mitochondrial outer membrane permeability (MOMP)—is often the “point of no return” for self-destruction, said Douglas Green, Ph.D., chair of the St. Jude Immunology ...

Treating HIV in war zones -- Public health emergencies need rapid advice from WHO

...s. "Our experience has shown us that one of the keys to successful provision of ART in conflict settings is preparation for disruption," say the authors. Some of the crucial contingency measures include: Providing patients with extra emergency drug supplies that can be taken in case of program ...

Technique monitors thousands of molecules simultaneously

...k. The nature and shape of molecules that serve as keys tells about the binding requirements of the receptor. Traditionally, probing a receptor this way has been done by making a library of molecules, treating it with the receptor, washing away any excess receptor that has not found a key, and then treati...

Corals that can fight global warming may one day help fragile reefs

...to fight them. But these complications can also be keys to coral reef survival. "A first line of defense is provided by surface microorganisms ?[that] produce antibiotics that can help corals fight pathogenic bacteria," reported Harvell. However, not all corals are able to produce such defenses under ...

Researchers first to map gene that regulates adult stem cell growth

...ole, it is possible that it also could provide the keys to new therapies. Van Zant describes his discovery as an elation. He worked on the project for six years with Ying Liang, a former graduate student who is now a postdoctoral fellow at UK. Van Zant said this research and publication of the journal a...

A giant among minnows: Giant danio can keep growing

...sts hope they can more easily identify the genetic keys to the difference in growth potential between them. According to co-author Peggy R. Biga, “I don’t think there will be a major genomic difference between them. I believe it will be easy to define the difference.? The study “Zebrafish and giant dani...

Gene discovery may shed light on kidney disease

...agille syndrome. "Ligands and receptors are like keys and locks," said Dr. Spinner. "If either one is defective, it may interfere with normal growth and development." Dr. Spinner's team previously determined that 94 percent of patients diagnosed with Alagille syndrome had mutations in the JAG1 gene. I...

Just the expectation of a mirthful laughter experience boosts endorphins 27 percent, HGH 87 percent

...xperiment, and three times afterward. "One of the keys in this kind of experiment is to set the baseline and control environment carefully," Berk said. "In this case, the control group basically sits in a 'neutral' room waiting to have their blood drawn, and on the tables there is a wide variety of magaz...

Thin tough skin, slow-growing gills protect larval Antarctic fish

...mished skin and slow developing gills appear to be keys to survival for newly hatched Antarctic notothenioids, a group of fish whose adults thrive in icy waters because of antifreeze proteins (AFPs) in their blood. Such adaptations are important, researchers at the University of Illinois atUrbana-Champai...

Effective, safe anthrax vaccine can be grown in tobacco plants

...nd vegetables such as carrots and tomatoes are the keys to figuring out a way for people to take anthrax vaccines orally in capsules of dried plant cells that contain correct doses of the protective antigen. If that research is successful, the needs for requiring doctors to administer the shots and for s...

Researchers discover stem cell 'guide' that may be key for targeting neural stem cell treatments

...June 24 issue of the journal Science. "One of the keys to developing promising new therapies for debilitating neurodegenerative diseases lies in our understanding of how new neurons are created and integrated into mature brain tissue," Zhou said. "This protein is an attractive drug target for either boos...

Survey reveals women and doctors aren't talking about HPV
