Alteration of MRP2 expression and the graft outcome after liver transplantation.

Purpose: Multidrug resistance-associated protein (MRP) 2 is a glutathione conjugate in the canalicular membrane of hepatocytes. Early graft damage after liver transplantation (LT) can result in alteration of MRP2 expression. The purpose of this study was to evaluate the relationship between the pattern of MRP2 alteration and graft outcome.

Early angiographic embolization is more effective than delayed angiographic embolization in patients with duodenal ulcer bleeding.

Background And Aim: Though angiographic embolization (AE) is a type of effective treatment modality for duodenal ulcer bleeding, the optimum time at which to perform the procedure, early or delayed, is unknown. The authors compared the prognosis of early AE (EAE) and delayed AE (DAE) in patients with duodenal ulcer bleeding.

Methods: A total of 54 patients with duodenal ulcer bleeding were evaluated with first-look endoscopy followed by AE.

Methodology matters: IVF versus ICSI and embryonic gene expression.

The use of assisted reproduction treatment, especially intracytoplasmic sperm injection (ICSI), is now linked to a range of adverse consequences, the aetiology of which remains largely undefined. Our objective of this study was to determine differences in gene expression of blastocysts generated by ICSI as well as ICSI with artificial oocyte activation (ICSI-A) versus the less manipulative IVF, providing fundamental genetic information that can be used to aid in the diagnosis or treatment of those adversely affected by assisted reproduction treatment, as well as stimulate research to further refine these techniques. Murine blastocysts were generated by ICSI, ICSI-A and IVF, and processed for a microarray-based analysis of gene expression.
