American Thoracic Society Journal news tips for April 2005 (first issue)

A study of 752 French patients found that shorter graft ischemic times were associated with improved long-term survival after single or double lung transplantation. The median ischemic time was 240 minutes, and a cutoff time of 330 minutes was identified as best discriminating between survivors and non-survivors.

Chemical compounds present in diet increase risk of colon cancer

Researchers found that certain dietary chemical compounds, such as PCBs, increase the risk of colon cancer by causing genetic alterations in genes like K-Ras and p53. The study suggests that diet plays a significant role in colorectal cancer development, with fat, red meat, and excessive calorie consumption being major risk factors.

How lupus T cells lose IL-2

Researchers found that sera from lupus patients contain antibodies that bind to T cells and suppress IL-2 production through CaMKIV. This deficiency in IL-2 contributes to the autoantibody production seen in lupus, highlighting a new understanding of how microenvironment influences defective T cell function.

Two-part blood pressure control suggests new approach to hypertension therapy

Research reveals kidneys and other systemic tissues have distinct roles in controlling blood pressure, challenging the dominant view that kidneys play a central role. The findings suggest that maximal efficacy of hypertension drugs requires complete blockade of receptors in both kidney and outside of kidney.
