Single-incision robotic-assisted living donor nephrectomy: case report and description of surgical technique.

The introduction of laparoscopic surgery, and more recently of robotics, has increased the number of living donor kidney transplants. This approach has already improved living donor acceptance rates. Even newer developments in the field have now been introduced with the purpose of further reducing postoperative pain and length of hospital stay, while offering better cosmetic results.

Dilute ammonia pretreatment of sorghum and its effectiveness on enzyme hydrolysis and ethanol fermentation.

A new pretreatment technology using dilute ammonium hydroxide was evaluated for ethanol production on sorghum. Sorghum fibers, ammonia, and water at a ratio of 1:0.14:8 were heated to 160 degrees C and held for 1 h under 140-160 psi pressure.
