Evaluating Sperm Recovery Time and Efficacy of Monotherapy Combination Therapies in Men with Congenital Hypogonadotropic Hypogonadism: A Systematic Review and Meta-Analysis.

Purpose: There is a lack of pooled data exploring the time and rates for human chorionic gonadotropin (hCG) monotherapy combination therapies (hCG+human menopausal gonadotropin or recombinant human follicle-stimulating hormone) to restore spermatogenesis in azoospermic men with congenital hypogonadotropic hypogonadism (CHH). We aimed to investigate the time and rates to recover spermatogenesis among azoospermic CHH men receiving monotherapy combination therapy.

Materials And Methods: We conducted a systematic review and meta-analysis following the PRISMA guidelines.

Demographics and Career Trends of Urology Fellowship Directors in the United States.

Introduction: Fellowship directors (FDs) hold significant leadership roles within the academic urology community. We sought to characterize common trends in training and academic productivity among urology FDs. Moreover, we aimed to characterize gender differences across subspecialties to better inform gender-based inclusion efforts and contemporary leadership pathways.

Novel and Structurally Diversified Bacterial DNA Gyrase Inhibitors Discovered through a Fluorescence-Based High-Throughput Screening Assay.

Bacterial DNA gyrase, a type IIA DNA topoisomerase that plays an essential role in bacterial DNA replication and transcription, is a clinically validated target for discovering and developing new antibiotics. In this article, based on a supercoiling-dependent fluorescence quenching (SDFQ) method, we developed a high-throughput screening (HTS) assay to identify inhibitors targeting bacterial DNA gyrase and screened the National Institutes of Health's Molecular Libraries Small Molecule Repository library containing 370,620 compounds in which 2891 potential gyrase inhibitors have been identified. According to these screening results, we acquired 235 compounds to analyze their inhibition activities against bacterial DNA gyrase using gel- and SDFQ-based DNA gyrase inhibition assays and discovered 155 new bacterial DNA gyrase inhibitors with a wide structural diversity.
