Researchers call for national database of epidural complications
04-02-2007 · EurekAlert!Complications following epidural pain relief can cause neurological damage and paralysis if less untreated. A six-year study of 8,100 patients has led researchers to call for a national database to estimate the risk of complications and other risk factors such as MRSA.

- Smaller is stronger -- now scientists know why
01-02-2008 · EurekAlert!
As metal structures get smaller -- as their dimensions approach the micrometer scale or less -- they get stronger. Now scientists from Lawrence Berkeley National Laboratory, Hysitron Inc. and General Motors Research and Development Center, working at the National Center for Electron Microscopy, have learned how. The researchers observed that compressing nanoscale pillars of nickel drives out dislocations and can produce a perfect crystal -- a process the researchers call "mechanical annealing."

- A molecular map for aging in mice
11-28-2007 · EurekAlert!
Researchers at the National Institute of Aging and Stanford University have used gene arrays to identify genes whose activity changes with age in 16 different mouse tissues. The study, published Nov. 30 in PLoS Genetics, uses a newly available database called AGEMAP to document the process of aging in mice at the molecular level. The work describes how aging affects different tissues in mice, and ultimately could help explain why lifespan is limited to just two years in mice.

- Smithsonian researcher probes Hope Diamond's fiery red glow
01-08-2008 · EurekAlert!
A study released in the January 2008 edition of the journal Geology proves that a blue diamond's rare appeal goes far beyond its beauty. The study was conducted by Jeffrey Post, curator of the National Gem Collection and mineralogist, at the Smithsonian's National Museum of Natural History. Post and six other researchers probed the mysterious phosphorescence of the Hope Diamond and other natural blue diamonds and discovered a way to "fingerprint" individual blue diamonds.

- New details on how the immune system recognizes influenza
01-01-2007 · EurekAlert!
Drawing upon a massive database established with funds from the National Institute of Allergy and Infectious Diseases, one of the National Institutes of Health, scientists have completed the most comprehensive analysis to date of published influenza A virus epitopes -- the critical sites on the virus that are recognized by the immune system. The findings, reported by researchers at the La Jolla Institute for Allergy and Immunology, are being published online this week by the journal Proceedings of the National Academy of Sciences.

- Testing delays cause severe AIDS complications, Einstein researchers find
11-02-2007 · EurekAlert!
Despite the availability of life-saving antiretroviral treatment, people infected with HIV continue to die and suffer from complications of AIDS, mainly due to delayed diagnosis and initiation of treatment. A researcher at the Albert Einstein College of Medicine of Yeshiva University and colleagues at Yale University have shed light on why this problem persists. They report their findings in the November issue of the journal Medical Care.

- Genes may interact with obstetric complications to boost schizophrenia risk
01-14-2008 · EurekAlert!
Researchers have proposed that such birth traumas may interact with certain gene variants to increase risk for the illness. Now, a new study by researchers at the National Institute of Mental health has identified specific genes involved in such interactions. Obstetric complications appeared to increase the impact of versions of genes affected by loss of oxygen or blood supply to the brain, as often occurs in such birth traumas.

- White blood cell booster may help cancer patients avoid deadly complications
07-25-2007 · EurekAlert!
Cancer patients who receive a drug that stimulates the growth of infection-fighting white blood cells may be significantly less likely to die from a chemotherapy-related complication characterized by fever and low white blood cell levels, according to a multi-institutional study led by researchers from the University of Rochester School of Medicine and Dentistry and the Duke University Comprehensive Cancer Center.

- Lupus gene finding prompts call for more DNA samples
12-02-2007 · EurekAlert!
Wellcome Trust researchers have identified a key gene involved in the disease lupus, which affects around 50,000 people in the UK, mostly women. The lead researcher behind the study has called for more patients to volunteer DNA samples to enable them to further study the underlying causes of the disease.
