The discovery could provide new strategies for treating HIV by targeting the protein's action.
The Vegetarian Diet Pyramid offers a well-balanced ovo-lacto vegetarian diet plan emphasizing fruits, vegetables, whole grains, and legumes. The pyramid recommends daily exercise and water intake, while optional foods include eggs and sweets.
African climate has abruptly turned from wet to dry in short time spans, every 1,500 years, according to Columbia University paleoclimatologist Peter deMenocal. This cycle matches a pattern of abrupt changes in the North Atlantic region and points to a persistent, naturally occurring cycle of climate change.
Researchers found that fragments of chromosome 11 slow tumor growth in mice and cell cultures, suggesting a tumor suppressor gene may be present. The study provides new hope for treating lung cancer patients by identifying a potential target for therapy.
Researchers found that using rapid diagnostic methods for M. tuberculosis can decrease diagnosis time from 38.5 to 23 days, time to therapy from 6.6 to 2.0 days, and mortality by 22-33%. This also reduces healthcare costs per patient.
Researchers are developing genetically altered, edible plant products to create new vaccines for sexually transmitted diseases. Plant-based proteins could be incorporated into pills, providing a cost-effective solution for vaccinations like hepatitis B.
Researchers at the University of Pennsylvania Medical Center have devised a unique procedure to transform monocytes into battle-ready dendritic cells, boosting the immune system's cancer-fighting forces. The modified cells have shown ability to activate T cells within one week.

They found that estrogen may activate an enzyme to increase the expression of neurotransmitter genes, facilitating learning and memory.
Researchers have discovered compounds in the bark of the pawpaw tree that show preliminary success in fighting some drug-resistant cancers. The compounds, called Annonaceous acetogenins, preferentially kill multidrug-resistant cells by inhibiting ATP production, pulling the plug on their energy source.
Researchers found that people with porphyria, a group of disorders causing chemicals to accumulate in the body, have low vitamin C levels in their blood. Increasing dietary levels of vitamin C may help prevent porphyrin accumulation and skin damage.
