Ferroelectric properties, narrow band gap and ultra-large reversible entropy change in a novel nonlinear ionic chromium(VI) compound.

A novel chromium(VI)-based compound, [(CHCH)N(CHCl)][CrOCl] (1), undergoes a high-temperature phase transition at around 340.9 K, accompanied by an ultra-large entropy change of 63.49 J mol K.

Efficacy and safety of Flos Abelmoschus manihot (Malvaceae) on type 2 diabetic nephropathy: A systematic review.

Objective: To evaluate the efficacy and safety of Flos Abelmoschus manihot (Malvaceae) on type 2 diabetic nephropathy (DN).

Methods: The Cochrane Library, PubMed/MEDLINE, Excerpta Medical Database, Chinese electronic literature databases, and the references of relevant articles were searched in March 2012 for randomized controlled trials (RCTs) that reported the effects of Flos A. manihot on type 2 DN patients with overt but subnephrotic-range proteinuria (500-3,500 mg/24 h).
