Microbial-induced Synthesis of nano NiFe LDH for High-efficiency Oxygen Evolution.

NiFe layered double hydroxide (LDH) currently are the most efficient catalysts for the oxygen evolution reaction (OER) in alkaline environments. However, the development of high-performance low cost OER electrocatalysts using straightforward strategies remains a significant challenge. In this study, we describe an innovative microbial mineralization-based method for in situ-induced preparation of NiFe LDH nanosheets loaded on nickel foam and demonstrate that this material serves as an efficient oxygen evolution electrocatalyst.

Osteoprotegerin, interleukin and hepatocyte growth factor for prediction of diabetes and hypertension in the third trimester of pregnancy.

Background: Gestational diabetes mellitus (GDM) raises the risk of high blood pressure and may cause a series of life-threatening complications in pregnant women. Screening and management of GDM and gestational hypertension (GH) in pregnancy helps to control and reduce these risks and prevent adverse effects on mothers and their fetuses. Currently, the majority criteria used for screening of diabetes mellitus is oral glucose tolerance tests, and blood pressure test is usually used for the screening and diagnosis of hypertension.

Effect of head circumference in combination with facial profile line on ultrasonic diagnosis of microcephaly.

Recently, microcephaly has usually been misdiagnosed only by ultrasound measurement of head circumference (HC). Therefore, the aim of this study is to find another diagnostic index to supplement the original diagnostic method of microcephaly, to improve the detection rate of fetal microcephaly and to reduce the misdiagnosis rate. We retrospectively analyzed 123 pregnant women from February 2012 to January 2017 with fetal HC less than two standard deviations (SD).
