Letrozole + Transcutaneous Electrical Acupoint Stimulation Improves Ovulation-Induced Pregnancy Rate in Obese Women with Polycystic Ovary Syndrome: A Prospective Cohort Study.

Objective: This study investigated the effect of letrozole with/without meridian-infusion percutaneous electrical stimulation on the rates of ovulation-induced pregnancy in patients with obese polycystic ovary syndrome (obPCOS).

Materials And Methods: Patients with obPCOS, ages 20-40, each with a body mass index (BMI) ≥24 kg/m, and/or waist circumference ≥80 cm, and at least 1 side tubal patency were enrolled at the Guangdong Women and Children Hospital, Guangzhou, China. They were divided into 2 groups: ZLT [ + transcutaneous electrical acupoint stimulation] and control.

Highly Chemoselective Ni-Catalyzed Protecting-Group-Free 2,2'-Biphenol Synthesis and Mechanistic Insights.

The utilization of readily available starting materials to produce useful molecules is often challenged by selectivity issues. In this study, a Ni-catalyzed protecting-group-free C-C coupling protocol is described for the efficient synthesis of 2,2'-biphenol derivatives. Its remarkable chemoselectivity control ability, wide substrate scope, and excellent functional group tolerance highlight this newly developed strategy.
