Mast cell mediators in relation to dengue severity: A systematic review and meta-analysis.

Background: Degranulation of mast cells (MCs) releases several mediators such as vascular endothelial growth factor (VEGF), chymase, tryptase, histamine, and cytokines, which all have important roles in the severity of dengue infection. We aimed to investigate the role of MCs in severity of dengue.

Methods: We searched for relevant studies in 10 databases on 15 August 2016.

Does No-Touch Technique Better than Conventional or Intermediate Saphenous Vein Harvest Techniques for Coronary Artery Bypass Graft Surgery: a Systematic Review and Meta-analysis.

Saphenous vein (SV) is a common graft being used in coronary artery bypass grafting (CABG). Conventional (CON), intermediate (I), and no-touch (NT) are the most common harvesting techniques of SV for CABG. The aim of this study is to systematically review the NT versus CON and I techniques in harvesting SV for CABG.
