The Moscow scientists have conducted clinical trials of a new method for treatment of deep burns of cornea. Their effort has been supported by the Russian Foundation for Basic Research.
Specialists of the Koltsov Institute of Developmental Biology, Russian Academy of Sciences, and the Gelmgolts Scientific Research Institute of Eye Diseases suggest that deep burns of cornea should be treated by transplanting artificial equivalent of stroma (the tissue directly underlying the cornea
Barely visible dust layer in the place of explosion would tell specialists where and when the explosive was produced. To this end, the dust should be preliminarily marked up in the way suggested by Russian researchers. The project was sponsored by the International Science and Technology Center.
When investigating the locus delicti after the explosion the experts face a significant problem. They can determine with high probability the kind and capacity of explosive device used
Doctor’s at Children’s Hospital of Pittsburgh are redefining early detection
Children’s Hospital of Pittsburgh Cardiologist Bradley B. Keller, MD, and his research team are discovering details in the lab that explain how the heart is formed in the embryo. This knowledge improves the chances of doctors identifying fetuses who can benefit from intervention to treat congenital defects.
Doctor’s in the Heart Center at Children’s are redefining wh
Besides adding flavor to food, onions also may be good for your bones. Researchers at the University of Bern in Switzerland have identified a compound in the popular vegetable that appears to decrease bone loss in laboratory studies using rat bone cells. Although further studies are needed, the current study suggests that eating onions might help prevent bone loss and osteoporosis, a disease which predominately affects older women. The disease results in an estimated $17 billion in medical costs
The number of days people stay home ill is influenced by neighborhood poverty and whether they receive subsidized health care, such as Medicaid, says a Purdue University urban sociologist.
“As state policy-makers decide whether to cut or invest in their state health insurance programs, such as Medicaid, they need to better understand factors, both systemic and individual, that influence whether and how people seek treatment for illnesses such as diabetes and high blood pres
A new brain imaging study of recently diagnosed schizophrenia patients has found, for the first time, that the loss of gray matter typically experienced by patients can be prevented by one of the new atypical antipsychotic drugs, olanzapine, but not by haloperidol, an older, conventional drug. The study, published in today’s Archives of General Psychiatry, also confirmed previous studies that show patients who experience less brain loss do better clinically.
“This is a really
Children on school buses collectively inhale as much or more exhaust emitted from those buses as does the rest of the city’s population, according to a new analysis by researchers at the University of California.
The results highlight the problem of “self-pollution,” or exhaust from the vehicle leaking into the cabin, particularly among older buses. This also is the first study to specifically look at how much exhaust is breathed in on school buses. “Although environmental regu
Harnessing the strength of a natural process that repairs damage to the human genome, a researcher from UT Southwestern Medical Center has helped establish a method of gene therapy that can accurately and permanently correct mutations in disease-causing genes. The findings are available online in Nature.
By artificially initiating a DNA repair process known as homologous recombination, Dr. Matthew Porteus of UT Southwestern, working with scientists from Richmond, Calif.-based
Scientists at New York University School of Medicine viewing the actual journey of immune cells in the liver have found that these cells travel in the liver’s blood vessels with surprising speed and agility.
It is the first time that the movement of live immune cells called natural killer T (NKT) cells has been seen in the liver, according to a study published in the April 5, 2005, issue of the Public Library of Science, an open-access, online journal.
NKT cells ar
Researchers have discovered that natural killer T (NKT) cells, the immune system’s sentinels, patrol the labyrinthine blood vessels of the liver for invaders or signs of tissue damage and demonstrate a dogged behavior not seen before in other T cells.
The new studies show that NKT cells crawl along vessel walls, even upstream against blood flow. They halt only when they receive a chemical signal to unleash an immune-system assault on marauding microbes, other invaders or dam
Today (April 4, 2005) at the 2005 Experimental Biology Conference, the Dairy Council of California sponsored a thought-provoking symposium titled “Individualized nutrition as a tool to prevent and treat chronic disease.” During the symposium attended by over 250 people, researchers, health professionals, nutritional scientists, and a panel of experts discussed how the progression from broad, population-based guidelines to more finely-tuned dietary recommendations and specific food choices will u
Researchers at the University of Iowa Roy J. and Lucille A. Carver College of Medicine have taken another step toward a potential treatment for Huntington’s disease (HD). Using an approach called RNA interference (RNAi), the scientists reduced levels of the disease-causing HD protein in mice and significantly improved the movement and neurological abnormalities normally associated with the disease.
HD is a devastating, inherited, neurodegenerative disease that is progressive
Researchers at the University of Illinois at Urbana-Champaign report dramatic evidence of the importance of visual cues in the control of food intake in the current issue of Obesity Research, a leading nutrition journal.
The researchers served a free soup lunch to 54 adults, half of whom ate from normal 18-ounce soup bowls, while the other half ate from identical bowls that, unbeknownst to the participants, were slowly refilled through tubing connected to out-of-sight soup cauldro
Learning disabilities such as dyslexia are believed to affect nearly one in 10 children. To better study them, a Northwestern University research team has developed a data-driven conceptual framework that links two well-established scientific concepts. In doing so, they also have developed a non-invasive diagnostic tool called BioMAP that can quickly identify children with learning disabilities.
Scientists have long recognized that children who can best process various aspects o
Scientists verify critical fabrication properties of gadolinium-nickel alloy
A new alloy developed and patented by researchers at Lehigh University, Sandia National Laboratory and Idaho National Laboratory could help the U.S. dispose more safely of 50,000 tons of spent nuclear energy fuel that are now stored at 125 sites in 39 states.
John DuPont, professor of materials science and engineering at Lehigh and principal investigator on the project, said that a nickel-based
Recognizing faces is effortless for most people, and it’s an ability that provides great evolutionary and social advantages. But this ability is impaired in people who have suffered brain damage or in those with a rare congenital condition, and research by Carnegie Mellon University psychologists reveals startling insights into how the brains of those individuals operate. Psychology Professor Marlene Behrmann and postdoctoral associate Galia Avidan have found that people with congenital pros
