Coevolution of RtcB and Archease created a multiple-turnover RNA ligase.

RtcB is a noncanonical RNA ligase that joins either 2',3'-cyclic phosphate or 3'-phosphate termini to 5'-hydroxyl termini. The genes encoding RtcB and Archease constitute a tRNA splicing operon in many organisms. Archease is a cofactor of RtcB that accelerates RNA ligation and alters the NTP specificity of the ligase from Pyrococcus horikoshii.

Arthroscopic treatment of meniscal tears: with all-inside suture technique: 1 years follow up results.

Background: In the last years meniscal repair surgeries have evolved to less invasive all-arthroscopic technique.

Purpose: To determine the short-term success rate and reoperation rate of all-inside meniscal sutures with a concomitant anterior cruciate ligament reconstruction.

Methods: Eighteen meniscal repairs were performed using an all inside suture technique.

The effects of bromocriptine on VEGF, kidney function and ovarian hyperstimulation syndrome in in vitro fertilization patients: a pilot study.

The aim of this study was to evaluate the effects of bromocriptine on vascular endothelial growth factor (VEGF) levels in serum, kidney function and ovarian hyperstimulation syndrome in women undergoing in vitro fertilization. Twenty-eight women were randomly divided into two groups and were administered daily oral capsules for 14 days, starting on the day of human chorionic gonadotropin (hCG) administration. Group A received 2.
