Oral Sex: Safety, Risks, Relationships, STD Transmission
WebMD discusses the health risks of oral sex, how to protect yourself, and more.
Study Findings Indicate A Key Step In The Generation Of White Matter And Understanding Developmental Disabilities
Through the identification of a gene's impact on a signaling pathway, scientists at Children's National Medical Center continue to make progress in understanding the mechanics of a key brain developmental process: growth and repair of white matter, known as myelination...
Study: MRSA Common Among Some Dental Students
Dental students in a Seattle study had very high rates of colonization with the MRSA, the drug-resistant strain of staph, raising new questions about the prevalence of the bacteria outside of hospitals in community health care settings.
The Hormonal Role In Glucose And Fat Metabolism Explained
Hormone researchers at the University of Houston (UH) have their sights set on providing long-term treatment options for diabetes, obesity and cardiovascular diseases by better understanding estradiol, the most potent naturally occurring estrogen. They now believe that this estrogen hormone is a prominent regulator of several body functions in both females and males. While estradiol is more commonly associated with processes and diseases specific to women, the team determined that the hormone actually functions as a unisex hormone with multiple actions...

A Shared Biological Basis For Diabetes And Cancer
Contrary to what you might think, cancer and diabetes appear to have some biology in common. According to a report in the Cell Press journal, Cell, a pathway that initially drew attention for its role in embryonic stem cells and cancer also influences the odds that mice develop or resist diabetes. Mice with high levels of the cancer-promoting proteins Lin28a or Lin28b become more sensitive to insulin and less prone to diabetes when on a high-fat diet, the new study shows. "This highlights the overlap in the biology of these disorders," said George Daley of Harvard Medical School...

Geneticists Develop Promising Mouse Model For Testing New Autism Therapies
UCLA scientists have created a mouse model for autism that opens a window into the biological mechanisms that underlie the disease and offers a promising way to test new treatment approaches. Published in the Sept. 30 edition of Cell, the research found that autistic mice display remarkably similar symptoms and behavior as children and adults on the autism spectrum. The animals also responded well to an FDA-approved drug prescribed to autism patients to treat repetitive behaviors often associated with the disease...
