Immune responses to peanuts are key in a growing allergic phenomenon

A study published in JCI Journals identified unique immunological factors produced by immune cells of peanut-allergic children compared to non-allergic individuals and those who outgrown their allergies. These findings suggest the development of allergic reactions depends on host immune response rather than inherent allergenic properties.

Study shows that women have as great a risk of dying from heart disease as men

Researchers at Cedars-Sinai Medical Center found that adenosine stress scans can identify women and men at high risk of death from heart disease. Diabetic women have a higher risk of cardiac death than diabetic men or other patients without diabetes, highlighting the importance of identifying patients at risk through effective therapies.

Families with severe form of bipolar disorder help scientists narrow the search for disease genes

Researchers studied 65 families with bipolar disorder and found strong genetic 'linkage' to specific regions on chromosomes 13 and 22, suggesting common genes contributing to both bipolar disorder and schizophrenia.
