Agricultural antibiotic use contributes to 'super-bugs' in humans

...a high rate of antibiotic prescribing in hospitals contributes to the emergence of drug resistant bacteria. But for some antibiotics, an even more important factor contributing to such emergence, argues a team of researchers in the open access international medical journal PLoS Medicine, is the use of antibiotic...

New study finds how cells with damaged DNA alert the immune system

...have shown here, it is certainly plausible that it contributes to the expression of the NKG2D ligand," said Raulet. "It may also be that the Rae1 ligand helps trigger T cell responses that contribute to long term specific immunity. It's certainly an area of research that warrants more study." Other co-authors o...

What Makes The Brain Tick, Tick, Tick: Researchers Gaining New Insights Into Brain's Internal Clock

...el, explained Buhusi, "each structure in the brain contributes its own resonance, and all these oscillations are monitored and integrated by the basal ganglia or striatal circuits. It's like a conductor who listens to the orchestra, which is composed of individual musicians. Then, with the beat of his baton, the...

Complex gene interactions account for autism risk

...hanism that normally stops or slows nerve impulses contributes to the disease. The team's findings implicate the so-called GABA receptor genes, which are genes that code for key components of "off switches" in the brain's neurons. GABA, or gamma aminobutyric acid, is a neurotransmitter ?a chemical that one neur...

Study provides insight into cellular defenses against genetic mutation

...herapies that interfere with it in cases where NMD contributes to disease-causing protein shortages." Researchers may be able to convert mRNA quality control from NMD over to a more flexible system that "overlooks" flaws, and provides more templates for building functional proteins. Genetic Decision Maker ...

Sudden change in social status triggers genetic response in male fish, study finds

...d of cellular underpinnings." The study also contributes to a growing body of scientific evidence that fish are more than mindless creatures that instinctively swim about in search of food and mates. "Our study shows that the male cichlid is obviously interacting with the world around it," says Burmeister,...

Molecular cabal contributes to stroke damage

...covered how an insidious chain of molecular events contributes to its damage. In an article in the November 23, 2005, issue of Neuron, Jun Gao and colleagues say that their findings could contribute to the development of drugs to protect against the molecular "cabal" that produces such lethality. In their exper...

NJIT study shows nanoparticles could damage plant life

...rger is the surface area, which we suspect is what contributes to the growth-slowing interaction between the seeds and the nanoparticles. The small size of the nanoparticles may be changed by the nanoparticles aggregating or clumping together." But what is still not understood, said Watts, is the nature of the...

Fish evolve a longer lifespan by evolving a longer reproductive period, researchers find

... increasing only that segment of the lifespan that contributes to "fitness" ?the relative ability of an individual to contribute offspring to the next generation. Focusing on guppies, small fresh-water fish biologists have studied for long, the researchers found that guppies living in environments with a large ...

Russian 'surrogate' alcohols are a killer

Heavy alcohol consumption contributes to numerous problems in Russia, not the least of which is a very high death rate. In an ongoing study of 25- to 54-year-old Russian men living in an industrial city, researchers have discovered that a significant proportion consume "surrogate" alcoh...

New understanding of regeneration gained by Forsyth scientists

... directly linking neighboring cells) communication contributes to this signaling. This research, led by Dr. Michael Levin, underlies principles that can potentially offer insight into human regeneration. The restoration of body structures following injury requires both an initiation of growth and an imposition ...

Looking for the genes that affect a person's level of response to alcohol

...nced phenotype, or measurable characteristic, that contributes toward the development of alcoholism," said Marc A. Schuckit, director of the Alcohol Research Center, Veterans Affairs San Diego Healthcare System, professor of psychiatry at the University of California, San Diego, and first author of the study.

Feds give researchers ok for safety test of adult stem cells in patients with heart disease

...50,000 people are diagnosed for the first time. It contributes to or causes about 300,000 deaths each year. About 1 percent of the U.S. population over the age of 65 is diagnosed with congestive heart failure each year. Existing therapies include drugs, gene therapy, and vascular interventions for relief of art...

The reason why antiviral therapy can't annihilate HIV infection, and what to do about it

...ivation of latently infected, resting CD4+ T cells contributes to the persistence of HIV and initiation of new infection cycles, co-administration of an effective and safe reagent that is capable of dampening cellular activation could minimize the spread of virions to uninfected bystander cells. ...

Birth defects: 8 million annually worldwide

...reased efforts to reduce birth defects in children contributes to the health of the entire population. Their recommendations in this report are aimed both at addressing health disparities between richer and poorer nations and at reducing the toll of infant deaths, especially in low- and middle-income countries....

Bones from blood: Scientists aim to break new ground on fractures

...rnance. They will also investigate how the project contributes to the debate about the ethics of stem cell research. In particular, they will consider how potential benefits of these stem cell therapies can be weighed against ethical concerns." ...

New drug could reduce tissue damage after heart attack

"The largest population of the East Bornean orangutan subspecies existing on Earth occurs in the forests of the Sabah Foundation conces...

Flesh-eating bacteria escape body's safety net

... experiments explain how this DNA-degrading enzyme contributes to the severe infections produced by certain strains of Strep bacteria, while simultaneously confirming just how important neutrophil DNA nets are to our normal immune defense," said Buchanan. Recognizing the critical role played by the DNA-degradin...
