Researchers have developed a computer program that represents a key step toward better understanding the connections between mutant genetic material and disease.
A new study shows that a kind of E. coli most associated with ‘travelers’ diarrhea’ and children in underdeveloped areas of the world causes more severe disease in people with blood type A. The bacteria release a protein that latches onto intestinal cells in people with blood type A, but not blood type O or B, according to a new study.
Increased rates of active travel (e.g., walking or cycling) to school in New Zealand children and youth were associated with shorter distances to school, and neighborhoods with more connected streets, less residential density, and lower socio-economic status, reveals a new systematic meta-analysis.
Scientists have made a significant discovery about how the vitamin content of some plants can be improved to make vegetarian and vegan diets more complete. Vitamin B12 (cobalamin) is an essential dietary component but vegetarians are more prone to B12 deficiency as plants neither make nor require this nutrient. But now a team, led by Professor Martin Warren, has proved that common garden cress can take up cobalamin.
Researchers have identified a subtype of the brain tumor medulloblastoma that is associated with improved survival of infants treated with less aggressive, risk-adapted therapy.
Prion diseases are slow degenerative brain diseases that occur in people and various other mammals. No vaccines or treatments are available, and these diseases are almost always fatal. Scientists have found little evidence of a protective immune response to prion infections. Further, microglia – brain cells usually involved in the first level of host defense against infections of the brain – have been thought to worsen these diseases by secreting toxic molecules that can damage nerve cells.
The US mental health system faces considerable challenges in delivering behavioral healthcare to populations in need.
