Nicotine exposure during development leads to hearing problems
Scientists know that children of women who smoke during pregnancy can develop hearing-related cognitive deficits. For the first time, researchers believe they have evidence that not only implicates nicotine as the culprit, but also shows what the substance does to the brain to cause these deficits. view more (2006-07-19)
New wrinkle in Botox treatment could lead to lower doses, better safety
There may soon be a better way to fight unsightly wrinkles. Researchers have discovered a novel way to increase the potency of botulinum neurotoxin treatments - commonly known as Botox - that they say could one day allow patients to receive the injections less frequently while maintaining or even enhancing its cosmetic benefits. view more (2006-04-06)
Reduced insulin in the brain triggers Alzheimer's degeneration
By depleting insulin and its related proteins in the brain, researchers at Rhode Island Hospital and Brown Medical School have replicated the progression of Alzheimer's disease - including plaque deposits, neurofibrillary tangles, impaired cognitive functioning, cell loss and overall brain deterioration - in an experimental animal model. view more (2006-03-23)
Drug helps cognitive function in brain tumor patients after radiation
A drug that is marketed to treat Alzheimer's disease also improves cognitive function, mood and quality of life in brain tumor patients following radiation therapy. view more (2006-03-20)
Alcoholism, smoking and genetics among Plains American Indians
Alcoholism and smoking have a high rate of co-occurrence in the general population. Yet little is known about the co-morbidity of alcoholism and smoking among American Indians. view more (2006-02-23)
Researchers show how air pollution can cause heart disease
New York University School of Medicine researchers provide some of the most compelling evidence yet that long-term exposure to air pollution-even at levels within federal standards-causes heart disease. view more (2005-12-21)
Defects in crucial brain protein implicated in memory loss
The ability to recognize familiar objects and companions is lost when levels of a protein crucial for recycling a chemical messenger in the brain are reduced, mimicking some of the symptoms of Alzheimer's disease. view more (2006-09-07)
Sage improves memory, study shows
NEW research has proved that sage can improve memory, confirming centuries-old theories. view more (2003-08-27)
Researchers discover mechanism that determines when detailed memories are retained
The levels of a chemical released by the brain determine how detailed a memory will later be, according to researchers at UC Irvine. view more (2006-10-16)
New technique helps researchers determine amino-acid charge
Measurements of the ion-current through the open state of a membrane-protein's ion channel have allowed scientists at the University of Illinois at Urbana-Champaign to obtain a detailed picture of the effect of the protein microenvironment on the affinity of ionizable amino-acid residues for protons. view more (2005-12-15)
Newly discovered small molecules
According to the study, these activators bind to specific sites on the neurotoxin protein, increasing protease activity and enhancing the toxin's effect. view more (2006-03-15)
Increased sensitivity to nerve signals keeps diabetes at bay
Nerve signals relayed directly to the pancreas after eating a meal play a critical role in normal blood sugar control. view more (2006-06-07)
Single genetic defect produces specific cognitive deficit in mice
Researchers have found that, in mice, producing a single genetic defect in a molecule that "reloads" neurons to trigger one another using the neurotransmitter acetylcholine impairs the mice's ability to recognize objects or other mice. view more (2006-09-07)
SLU researchers show how to stop muscle weakness caused by myasthenia gravis
Severe muscle weakness caused by myasthenia gravis - a highly debilitating autoimmune disorder - can be prevented or reversed by blocking a key step in the immune response that brings on the disease, researchers at the Saint Louis University School of Medicine have found. view more (2007-12-21)
Dissecting the machinery of nicotine's reward
Understanding what makes people crave the high of nicotine is a key to developing treatment for this highly addictive drug. And that understanding involves tracing the neural machinery by which nicotine switches on the brain's reward machinery. view more (2006-06-15)
Researchers ID gene linked to lung cancer
Researchers at Johns Hopkins, as part of a large, multi-institutional study, have found one gene variant that is linked to an increased risk of lung cancer. The study will be published in the April 3 issue of Nature Genetics. view more (2008-04-03)
Mechanism of nicotine's learning effects explored
While nicotine is highly addictive, researchers have also shown the drug to enhance learning and memory—a property that has launched efforts to develop nicotine-like drugs to treat cognitive deficits in Alzheimer's and Parkinson's diseases, schizophrenia, and attention-deficit/hyperactivity disorder. view more (2007-04-05)
Synthetic Cannabinoid May Aid Fertility in Smokers
A reproductive medicine specialist at the University at Buffalo has shown that a new compound may improve the fertility of tobacco smokers who have low sperm count and low percentage sperm motility. view more (2006-12-04)
Scripps research scientists: Compounds show significant promise against potential bioweapon toxins
Because of the high cost and limited applicability of currently available treatments, the newly identified compounds have the potential to fill the existing therapy gap and to provide protection against a bioterrorism attack using the toxin. view more (2007-02-06)
Scientists discover a direct route from the brain to the immune system
It used to be dogma that the brain was shut away from the actions of the immune system, shielded from the outside forces of nature. But that's not how it is at all. In fact, thanks to the scientific detective work of Kevin Tracey, MD, it turns out that the brain talks directly to the immune system, sending commands that control the body's... view more...
