Shape and function of the heart improves with apnea treatment

Patients with obstructive sleep apnea have enlarged and thickened hearts that pump less effectively, but the heart abnormalities improve with use of a device that helps patients breathe better during sleep, according to a new study in the April 4, 2006, issue of the Journal of the American College of Cardiology.

Underutilization of partial nephrectomy for localized renal cell carcinoma in the U.S.

In the past, the gold standard for the treatment of localized renal tumors has been radical nephrectomy. Over time however, experience with nephron sparing surgery and, now, laparoscopic approaches have demonstrated oncologic equipoise and may provide for an improved quality of life for patients as compared to those undergoing radical nephrectomy for localized renal masses.

A map of recent positive selection in the human genome

By scanning the entire human genome in search of genetic variations that may signal recent evolution, University of Chicago researchers found more than 700 genetic variants that may be targets of recent natural positive selection during the past 10,000 years of human evolution.
