Opiates Better Than Sedatives For Treating Newborns In Withdrawal

...by use of morphine instead of phenobarbitone. This helps keep mothers and babies together, helps in educating the mothers in mothercraft skills and to recognize signs of infant withdrawal, and help...

Researchers discover new route to hemoglobin synthesis

Targeting a key enzyme with gene therapy reversed course of Alzheimer's disease in mouse models

...ference, they were able to turn down the gene that helps produce the characteristic amyloid plaques that are one of the hallmarks of Alzheimer's disease. "Within a month of treatment, mice that had already suffered memory deficits could learn and remember how to find their way through a water maze," says ...

Researchers find molecule that inhibits regrowth of spinal nerve cells

A molecule that helps the body's motor nerve cells grow along proper pat...t UT Southwestern have been studying how ephrin-B3 helps control how and where nerve fibers grow during early development. They previously showed that the mo...

From a Few Wild Ancestors, a Citrus Cornucopia

...ry for Citrus and Dates, in Riverside, California, helps look after the nation’s largest collection, or genebank, of citrus trees. The trees, as well as their seeds, budwood, and pollen, serve as valuable germplasm—plant tissue containing the essential genetic information needed to start new citrus plants....

Researchers discover how malaria parasite disperses from red blood cells

...f the cytoskeleton, the molecular scaffolding that helps the cell to maintain its rounded shape. In the next stage, called the "flower" stage, the red blood cell assumes a roughly spherical shape, covered with rounded structures that resemble the petals of a flower. Shortly thereafter, the blood cell's m...

Protein structure key for AIDS, cell function

...question for biologists." It turns out that CD38 helps produce at least two calcium messenger molecules, each of which then opens channels for the release of calcium from specific stores, or reservoirs, within cell organelles. High intensity X-rays made it possible to pass photons through a protein crys...

Methamphetamine Abuse, HIV Infection Cause Changes in Brain Structure

...n the volume of the brain’s parietal cortex (which helps people to understand and pay attention to what’s going on around them) and basal ganglia (linked to motor function and motivation). HIV infection is associated with prominent volume losses in the cerebral cortex (involved in higher thought, reasoning...

Genomics researchers discover protein deficit that causes drug toxicity

...pply to many instances in the field." The finding helps explain what goes wrong under certain genetic conditions -- and suggests mechanisms which might help predict which genetic changes could alter the effect of drugs. Prior efforts to explain the mystery of thiopurine metabolism had focused on biochemic...

NYU chemists use computer simulation to enhance understanding of DNA transcription

...NA in a chromosome, this computer simulation study helps to understand the mechanism of gene expression and silencing. ...

Scientists create digital bacteria to forge advances in biomedical research

... sensitivity of E. coli's chemotaxis system, which helps the bacteria find food. "When you changed the level of that protein, it would change the sensitivity of the cell," Emonet said. Subsequent laboratory experiments came out exactly the same way. Sometimes, though, conducting the actual experiment woul...

Computer modeling reveals hidden conversations within cells

...biochemists have developed a computer program that helps explain a long-standing mystery: how the same proteins can play different roles in a wide range of cellular processes, including those leading to immune responses and cancer. Prior to the UCSD team's findings, which are published in the September 1...

Scientists use gene transfer technology and common virus to block neuropathic pain in animals

...tantially greater for neuropathic pain, because it helps correct the reduction of GABA in the spinal cord. He also emphasizes the excellent safety record of the HSV vector, which has produced no side effects or complications in many animal studies. “I am a clinical neurologist and I see patients with neur...

Einstein researchers identify new way that bacteria develop resistance to antibiotics

...he drugs target an enzyme called DNA gyrase, which helps untwist bacterial DNA during replication. However, TB has been developing resistance to fluoroquinolones due to their increasing use in treating multi-drug-resistant TB infections. Until recently, this resistance was due entirely to mutations in DNA...

Breast tumors in mice eradicated using cancer vaccine

...as macrophages, dendritic cells, and T cells. This helps jump-start the immune response to break tolerance. But, why Listeria over other bacteria as a vehicle to deliver a tumor-associated antigen? Because of Listeria's unusual life style. Normally, when bacteria get taken up into an antigen-presenting c...

Genetic variation alters response to common anti-clotting drug

...ide reductase (VKORC1), which makes a protein that helps control clotting and is the key target of warfarin. The researchers analyzed the VKORC1 gene's DNA sequence in 186 patients on a stabilized dose of warfarin. They searched for common DNA variations responsible for changing the gene's activity and the...

Firefly protein lets researchers monitor molecule linked to cancer

...ystem to produce a full dose-response curve, which helps establish how to best use a drug," Piwnica-Worms says. "Establishing that normally takes 6 months and 300 mice. With our monitoring technique, Shimon did it in a 5-day period using 30 mice. That's going to lead to tremendous cost savings." Because t...

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

... 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 of the paper are Sandra Orsulic, assistant professor at the Massachusetts General Hospital Center...

Researcher at UGA College of Veterinary Medicine identifies new way of combating viral diseases

...his colleagues report that blocking a protein that helps transport viruses out of a cell keeps these four viruses from reproducing and infecting other cells. Most antiviral therapies target the virus itself, but viruses are quick to adapt to the body's attempts to disable them, Hodge explained. They can m...
