The National Human Genome Research Institute (NHGRI), part of the National Institutes of Health (NIH), today awarded more than $20 million in grants to develop innovative sequencing technologies inexpensive and efficient enough to sequence a person's DNA as a routine part of biomedical research and health care.

The majority of deaths during the influenza pandemic of 1918-1919 were not caused by the influenza virus acting alone, report researchers from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. Instead, most victims succumbed to bacterial pneumonia following influenza virus infection. The pneumonia was caused when bacteria that normally inhabit the nose and throat invaded the lungs along a pathway created when the virus destroyed the cells that line the bronchial tubes and lungs.

The largest genetic analysis of its kind to date for bipolar disorder has implicated machinery involved in the balance of sodium and calcium in brain cells. Researchers supported in part by the National Institute of Mental Health, part of the National Institutes of Health, found an association between the disorder and variation in two genes that make components of channels that manage the flow of the elements into and out of cells, including neurons.

New research indicates that giving patients a continuous low dose of an immune system booster, a method known as metronomic dosing, as part of a therapeutic prostate cancer vaccine strategy is safe and produces similar immune responses and fewer side effects than the more common dosing method, which is not well tolerated by many patients. This study, led by researchers at that National Cancer Institute (NCI), part of the National Institutes of Health, was published in the Aug. 15, 2008, issue of "Clinical Cancer Research."

Cutaneous leishmaniasis, a disease characterized by painful skin ulcers, occurs when the parasite Leishmania major, or a related species, is transmitted to a mammalian host by the bite of an infected sand fly. In a new study from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, scientists have discovered L. major does its damage by not only evading but also by exploiting the body's wound-healing response to sand fly bites, as reported in the August 15 issue of "Science."

Scientists at the National Institutes of Health (NIH) have found a mechanism in the immune systems of mice that can lead to the development of autoimmune disease when turned off. The findings shed light on the processes that lead to the development of autoimmunity and could also have implications for the development of drugs to increase the immune response in diseases such as cancer and HIV. The study paper appears online today in the journal "Nature."

People with schizophrenia have an alteration in a pattern of brain electrical activity associated with learning and memory. Now, researchers from the National Institutes of Health and Sweden's Karolinska Institute have identified in mouse brain tissue a molecular switch that, when thrown, increases the strength of this electrical pattern. The researchers found that adding the brain chemical Neuregulin-1 to the brain tissue boosted the electrical signals that the tissue generated.

Despite considerable progress in research to understand the health effects of vitamin D, experts convened by the NIH to review the available data found major gaps in the evidence. The data are strongest in the area of bone health among elderly men and post-menopausal women, suggesting that increased vitamin D intake can improve bone health and prevent falls. For other age groups and health issues, though, it is too early to say conclusively whether more vitamin D might be beneficial.

Robert H. Carter, M.D., former director of the Division of Clinical Immunology and Rheumatology at the University of Alabama at Birmingham (UAB), has been selected as deputy director of the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), a part of the National Institutes of Health (NIH). Dr. Carter will be assuming his official responsibilities as of October 1, 2008.

Highly active antiretroviral therapy (HAART) has been extremely effective at slowing the progression of HIV infection to AIDS as well as extending the lives and improving the quality of life for those with HIV. However, some doctors have been reluctant to prescribe HAART to HIV-infected injection drug users because of concern that they may not fully benefit from the therapy. A new study by investigators funded by the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health, and led by the British Columbia Centre for Excellence in HIV/AIDS in Canada, suggests that this is not the case: in their large, community-based study of HIV-infected people, injection drug users and people who did not inject drugs had equivalent survival rates seven years after initiating HAART. These results will be published August 6 in the "Journal of the American Medical Association."

The NIDA NewsScan #54 examines the latest findings on drug abuse among youth as well as key issues including the relationship between marijuana and the perception of pain, the role emotions play in smoking, and innovative approaches to pain management through virtual reality. The National Institute on Drug Abuse (NIDA) is part of the National Institutes of Health (NIH).
