For Some Diabetics, Burden Of Care Rivals Complications Of Disease
Many patients with diabetes say that the inconvenience and discomfort of constant therapeutic vigilance, particularly multiple daily insulin injections, has as much impact on the quality of their lives as an intermediate complication. On average, patients considered the burden of comprehensive diabetes care comparable to that of angina, nerve or kidney damage. Blood Pressure Drug May Curb Brain Damage From Alzheimer's, Depression
A drug used to treat high blood pressure and enlargement of the prostate may protect the brain from damage caused by post-traumatic stress disorder, Alzheimer's disease, depression and schizophrenia. Prazosin, also prescribed as an antipsychotic medication, appears to block the increase of steroid hormones known as glucocorticoids, researchers have found. Elevated levels of glucocorticoids are associated with atrophy in nerve branches where impulses are transmitted, and even nerve cell death, in the hippocampus. Master Regulatory Gene Found That Guides Fate Of Blood-producing Stem
Researchers from the University of Pennsylvania School of Medicine found that a protein called NF-Ya activates several genes known to regulate the development of hematopoietic stem cells (HSC), or blood-producing stem cells, in bone marrow. Knowing the details of this pathway may one day lead to new treatments for such blood diseases as leukemia, as well as a better understanding of how HSCs work in the context of bone-marrow and peripheral-stem-cell transplantation. Education Linked To Risk Of Cancer Death
A new American Cancer Society study finds having at least some education beyond high school is strongly associated with a decreased risk of cancer death. For all cancer sites combined, death rates among white and black men with the lowest (0-8 years) level of education were about three times higher than those with the highest (17+ years) level of education. Brain Imaging Study May Hold Clues To Onset Of Schizophrenia In People
Images of brain activity may hold clues to the onset of schizophrenia in people at high risk for the disease, according to a study headed by psychiatry researchers at the University of North Carolina at Chapel Hill School of Medicine. Intergalactic 'Shot In The Dark'Shocks Astronomers
Astronomers have discovered a cosmic explosion that seems to have come from the middle of nowhere -- thousands of light-years from the nearest galaxy-sized collectionof stars, gas, and dust. This "shot in the dark"is surprising because the type of explosion, a long-duration gamma-ray burst, is thought to be powered by the death of a massive star. Vietnam Veterans Memorial Wall Page
Names on the wall can be searched by any two of name, home, military branch, age, service #, rank, birthdate, or casualty date; or by panel location. Information on each person can include age; rank; home state; marital status; race; religion; length of service; and the date, place, and cause of their death. Names can also be browsed alphabetically. There is a page of Vietnam maps and another of casualty statistical summaries. Comments and pictures can be added to a person's information record. There is a message center and a list for exchange of bracelet information. This site is maintained by a nonprofit veterans group. 'Plastic Oil' Could Improve Fuel Economy In Cars, Chemists Say
Recycled plastic bottles could one day be used to lubricate your car's engine, according to researchers at Chevron and the University of Kentucky, who in laboratory experiments converted waste plastic into lubricating oil. These polyethylene-derived oils, they say, could help improve fuel economy and reduce the frequency of oil changes. The pilot study appears in the July 20 issue of the American Chemical Society's peer-reviewed journal Energy &Fuels. 'Promiscuous' Area Of Brain Could Explain Role Of Antidepressants
A study at Baylor College of Medicine in Houston may lead to a better understanding of how antidepressants like Prozac work -- and how to make them more effective.According to results published in today's issue of the journal Neuron, a study in mice proposes that dopamine and serotonin neurotransmitter systems in the brain occasionally get their signals crossed, causing delays in stabilizing mood. Triage Study Challenges Notions Of Emergency Medical Response To Disas
In the face of terrorism and catastrophic natural disasters, modern regional trauma systems that improve survival for critically injured patients are more vital than ever. Scientists have now created a computer simulation model of trauma system response to mass casualty incidents involving dozens or hundreds of injured victims.
