Nearly half of all HIV-positive African adults who become infected with Salmonella die from what otherwise would be a seven-day bout of diarrhea. Now, scientists have discovered how salmonella becomes lethal for AIDS patients.

What many diabetic patients may not know is that the medications that help control healthy insulin levels may lead to unexpected events at the dentist's office. According to a new study, diabetic patients especially need to communicate special needs to their dentists. This is due to harmful interactions that could occur because of the materials and medications used at dental appointments.

Therapeutic cloning, also known as somatic-cell nuclear transfer, can be used to treat Parkinson's disease in mice. For the first time, researchers showed that therapeutic cloning or SCNT has been successfully used to treat disease in the same subjects from whom the initial cells were derived. While this current work is in animals, it could have future implications as this method may be an effective way to reduce transplant rejection and enhance recovery in other diseases and in other organ systems.

A study involving several Major League Baseball pitchers indicates that the height of the pitcher's mound can affect the athlete's throwing arm motion, which may lead to potential injuries because of stress on the shoulder and elbow.

Cigarette smokers who were treated for cerebral aneurysms with coil embolization (blocking of a blood vessel) are at greater risk of developing another aneurysm, say neurological surgeons.

A number of promising new drug targets for Huntington's disease, a neurodegenerative disease, have emerged. Scientists have identified a number of candidate drugs to investigate further which encourage cells to "eat" the malformed proteins that lead to the disease.

Researchers have identified a potential new neuronal tumor suppressor. Neural crest-derived tumors include neuroblastomas and medulloblastomas, which are the most common malignant pediatric solid tumors, as well as paragangliomas (relatively rare tumors of the sympathetic nervous system) and melanomas, the deadliest form of skin cancer.

A dental research team has discovered evidence that pregnant women with periodontal disease are more likely to develop gestational diabetes mellitus than pregnant women with healthy gums.

It has long been known that psoriasis, a chronic skin condition characterized by thick, red, scaly plaques that itch and bleed, can have a significant negative impact on a patient's overall quality of life. Now, dermatologists are finding that psoriasis, especially severe psoriasis, is linked with a number of serious medical conditions -- including cardiovascular disease, depression and cancer.

Mathematicians have developed powerful new tools for winnowing out the genes behind some of humanity's most intractable diseases. With one, they can cast back through generations to pinpoint the genes behind inherited illness. With another, they have isolated 11 variations within genes -- called single nucleotide polymorphisms, SNPs or "snips"--associated with type 2 diabetes.
