Staphylococcus aureus hides out in cells

...otentially lethal for the epithelial cells becomes strictly controlled to limit cellular damage. Mechanisms that helped the bacteria to survive and/or multiply, including metabolic and energy production functions, then resumed. Although most of the bacteria had died by about four days as a result of antibioti...

Cracking open the black box of autoimmune disease

...s take a tremendous toll on human health, but on a strictly molecular level, autoimmunity is a black box," says Young. "When we discover the molecular mechanisms that drive these conditions, we can migrate from treating symptoms to developing treatments for the disease itself."...

Uncovering DNA's 'sweet' secret

...f homo-DNA requires that the pairing strands align strictly in an antiparallel fashion - unlike DNA which can adopt a parallel orientation. Finally,the irregular spaces between the "rungs" prevent homo-DNA from taking onthe uniform structure DNA uses to store genetic information. The findings suggest that f...

Ongoing collapse of coral reef shark populations

...reef shark abundance was only apparent on the most strictly enforced of the no-take zones, suggesting that even moderate levels of poaching can derail attempts to protect shark populations. These observations, coupled with population modeling showing ongoing, rapid declines in population size in fished areas,...

Viral marker of human migration suspect

Brighter future for giant panda?

...rnment including a network of natural reserves and strictly enforced bans on poaching and deforestation. However, given the variable accuracy of traditional ecological population recording methods, scientists from Cardiff's School of Biosciences working with a team in China used a novel approach to accurate...

Avian flu modeled on supercomputer, explores vaccine and isolation options for thwarting a pandemic

...rategies is more likely to be effective than a few strictly enforced ones," said Kadau, also of Los Alamos' Theoretical Division. The model of disease transmission involves probabilities that any two people in a community will meet on any given day in any one of a number of settings, such as home or workplac...

...egulate the manufacture and use of PCBs and DDT as strictly as the United States does now, and these compounds continue to be released into the marine environment. "The increases we saw compared with ten years ago probably reflect the ongoing use of these chemicals in countries that border the Pacific," Fin...

Albatross study shows regional differences in ocean contamination

A step forward in the fight against bacterial infections

...om our body. Of course, this chain of reactions is strictly controlled, because excessive inflammation can lead to lethal shock. Mice that are able to cope with acute inflammations Tina Mahieu and her colleagues from the research group led by Claude Libert are working with mice that are not susceptible t...

Possible brain hormone may unlock mystery of hibernation

...irst demonstrated that hibernation in chipmunks is strictly controlled by an individual's internal circannual rhythm even under conditions of constant cold. In 20 hibernators examined throughout their lives, concentrations of HPc in the blood started to decrease prior to hibernation and remained low throughou...

...(= promoter). Biological processes in our body are strictly regulated, primarily by closely controlling the amount of each protein that is produced. The promoter of a gene has the most important control function in this process. In younger Belgian and Dutch Alzheimer's patients (younger than 70), the resear...

High-tech tags on marine animals yield valuable data for biologists and oceanographers

...l to find food. They've always been described as a strictly coastal species, but they went as far out as 300 miles from the coast," he said. At the same time, Costa's group was also tracking the movements of elephant seals and albatrosses. These species, which typically forage across a broad area of the Nort...

Brain activity related to processing faces is similar in people with, without autism

...m approach facial stimuli without anxiety. This is strictly conjecture, but it is a tantalizing possibility," Dichter said. Imaging allows researchers to begin looking at underlying mechanisms in brain function, Belger said. "Still, we must be careful in our interpretation of the results. Our findings need ...

Cats' indifference towards sugar explained

"We took a behavioral question and answered it molecularly," says Joseph Brand, senior author of the study and Associate Director of the Monell Chemical Senses Center.

Bioinformatics reveals new gene regulation system

... of 63 bacteria species, looking for proteins that strictly followed the same present-or-absent pattern as the NrdR-box. Only one protein cluster matched the pattern, and it represented a family of proteins that shared traits of transcription factors. To strengthen the prediction that these proteins were the...

Hopkins AIDS experts issue warning about global efforts to provide drug therapies

Initially, however, who would most likely adhere to hemodialysis therapy was determined by using "social-worth" criteria that favored members of the middle class, from whose ranks came the ...
