Enhancing oocyte competence in patients with polycystic ovarian syndrome: A microfluidic study on the effects of follicular fluid meiosis-activating sterol in in vitro oocyte maturation.

Objective: To evaluate the efficacy of a microfluidic culture system supplemented with follicular fluid meiosis-activating sterol (FF-MAS) on the maturation of immature oocytes in patients with polycystic ovarian syndrome (PCOS).

Methods: A total of 438 germinal vesicle oocytes from 163 PCOS patients were included. Oocytes were divided into five groups: (1) cultured in static drops without FF-MAS, (2) cultured in static drops with FF-MAS, (3) cultured in a microfluidic device without FF-MAS, (4) cultured in a microfluidic device with FF-MAS for the first 2 h, and (5) cultured in a microfluidic device with FF-MAS for 24 h.

Simulation and optimization of the impacts of metal-organic frameworks on the hydrogen adsorption using computational fluid dynamics and artificial neural networks.

One of the barriers to further commercialization of the proton exchange membrane fuel cell (PEMFC) is hydrogen storage. Conventional methods are based on pressurizing the hydrogen up to 700 bar. The focus of this study is to characterize the hydrogen storage capacity of hydrogen tanks filled with MOF-5 at low pressures.
