Exploring bat-inspired cyclic tryptophan diketopiperazines as ABCB1 Inhibitors.

Chemotherapy-induced drug resistance remains a major cause of cancer recurrence and patient mortality. ATP binding cassette subfamily B member 1 (ABCB1) transporter overexpression in tumors contributes to resistance, yet current ABCB1 inhibitors have been unsuccessful in clinical trials. To address this challenge, we propose a new strategy using tryptophan as a lead molecule for developing ABCB1 inhibitors.

Health-related quality of life, psychological well-being, and sexual function in patients with benign prostatic hyperplasia after prostatic surgery.

Aims And Background: Patients with benign prostatic hyperplasia (BPH) may receive prostatic surgery due to severe lower urinary tract symptoms (LUTS). This study aimed to investigate the health-related quality of life (HRQoL), psychological well-being, and sexual function of patients with BPH after prostatic surgery and identify the predictors of HRQoL among this group of patients.

Methods: This was a cross-sectional, descriptive, correlational study.
