It has been known that severe stress lasting weeks or months can impair cell communication in the brain’s learning and memory region, but this study provides the first evidence that short-term stress has the same effect.
%26quot;Stress is a constant in our lives and cannot be avoided,%26quot; said Dr. Tallie Z. Baram, the Danette Shepard Chair [...]
Their research has also shown that this association was particularly strong in females compared to males. The group speculates that this may be a result of gender differences in the way the body handles and stores iron.
Though the results are based on a small number of samples, they give an indication that iron accumulation associated [...]
In surprising new research, published in the journal Neuron, Julie Kauer and her team show that activation of TPRV1 receptors can trigger long-term depression, a phenomenon that creates lasting changes in the connections between neurons. These changes in the brain %26ndash; and the related process of neural reorganization known as long-term potentiation %26ndash; are believed [...]
The research, which will be published in the March 13 issue of Science Express, now makes it possible not only to systematically improve upon the repellent properties of DEET but also to make it a safer chemical.
%26quot;For all these years, there were a lot of theories but no consensus on how DEET worked,%26quot; says [...]
The knowledge suggests new ways science may be able to turn off rogue macrophages that are the root cause of the many inflammatory diseases ranging from atherosclerosis to arthritis and that provide the mechanism for tissue and organ rejection after transplant.
There is also evidence that some types of cancer cells over-express the molecular protein that [...]
Michigan State University has developed a new technique to test the DNA of E. coli bacteria by examining very small genetic changes called single nucleotide polymorphisms or SNPs (pronounced snips). Using SNPs, scientists analyzed 96 markers, making genetic analysis of pathogenic bacteria possible at a rate never before accomplished.
%26quot;It used to take three months to [...]
The study, which appears in the March 15 issue of Clinical Infectious Disease, confirmed the suspected close link between the two most common diseases of young children, viral colds and ear infections. It also identified the viruses associated with higher rates of ear infections.
%26quot;Understanding how viruses and ear infections are linked will definitely help us [...]
No one knew what was wrong with her. At age 25 she seemed too young to be having a stroke.
As Jim Cody, 69, lay in his hospital bed recovering from knee replacement surgery, a tiny fat particle traveled to his brain. Soon he was unable to move or talk.
What Cody and Weiler didn’t know [...]
With deaths from falls increasing, the guidelines urge doctors to ask patients to ‘fess up.
Better would be to prevent even that first fall. Now scientists are testing simple wrist monitors that may one day be used to predict who is most likely to topple, by tracking how stable they are with each step on any [...]
He puts six pills in his mouth and, with a shaky hand, brings a glass of water to his lips. Six down and 19 to go.
Lammers takes 25 pills a day to control his worsening Parkinson’s disease. He has to use a partially filled glass of water, just like everything else he drinks, because his [...]
