The Role and Mechanism of Hydrogen-Rich Water in the Response to Chilling Stress.

Cucumber is a warm climate vegetable that is sensitive to chilling reactions. Chilling can occur at any period of cucumber growth and development and seriously affects the yield and quality of cucumber. Hydrogen (H) is a type of antioxidant that plays a critical role in plant development and the response to stress.

Tunneled dialysis catheter exchange through fibrin sheath crevice vs in situ catheter exchange for the treatment of catheter dysfunction.

Our aim is to evaluate the safety and efficacy of tunneled dialysis catheter (TDC) exchange through fibrin sheath crevice vs in situ catheter exchange in hemodialysis patients with fibrin-sheath-related catheter dysfunction. Patients with fibrin-sheath-related catheter dysfunction who underwent TDC exchange in our center between 2012 January and 2017 December were retrospectively screened. The included patients were divided into the sheath-crevice group (catheter was exchanged through fibrin sheath crevice) and the in situ group (catheter was exchanged in situ).
