Analysis of the implementation value of abdominal B-ultrasound combined with cervical cerclage in the prevention and treatment of late recurrent spontaneous abortion.

Objective: To study the implementation value of abdominal B-ultrasound combined with cervical cerclage in the prevention and treatment of recurrent late abortion.

Methods: From October 2020 to December 2023, 196 pregnant patients who had a history of late abortions at our institution were chosen. They were divided into groups based on the treatments used.

Momordica Grosvenori Shell-Derived Porous Carbon Materials for High-Efficiency Symmetric Supercapacitors.

Porous carbon materials derived from waste biomass have received broad interest in supercapacitor research due to their high specific surface area, good electrical conductivity, and excellent electrochemical performance. In this work, Momordica grosvenori shell-derived porous carbons (MGCs) were synthesized by high-temperature carbonization and subsequent activation by potassium hydroxide (KOH). As a supercapacitor electrode, the optimized MGCs-2 sample exhibits superior electrochemical performance.
