Low Levels of Brain Chemical May Lead to Obesity, NIH Study of Rare Disorder Shows
A brain chemical that plays a role in long term memory also appears to be involved in regulating how much people eat and their likelihood of becoming obese, according to a National Institutes of Health study of a rare genetic (...)

Common Treatment to Delay Labor Decreases Preterm Infants' Risk for Cerebral Palsy
Preterm infants born to mothers receiving intravenous magnesium sulfate -- a common treatment to delay labor -- are less likely to develop cerebral palsy than are preterm infants whose mothers do not receive it, report researchers in a large National Institutes of Health research (...)

NHGRI Seeks DNA Sequencing Technologies Fit for Routine Laboratory and Medical Use
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 (...)

Bacterial Pneumonia Caused Most Deaths in 1918 Influenza Pandemic
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 (...)

Largest Study of Its Kind Implicates Gene Abnormalities in Bipolar Disorder
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 (...)

Alternative Vaccine Strategy Shows Promise in Prostate Cancer Patients
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, (...)

Researchers Find Leishmaniasis Parasites Evade Death by Exploiting the Immune Response to Sand Fly Bites
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 (...)

NIH Scientists Find a Novel Mechanism that Controls the Development of Autoimmunity
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 (...)

Molecular Switch Boosts Brain Activity Associated with Schizophrenia
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, (...)

Key Gaps Remain in Understanding Health Effects of Vitamin D
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 (...)
