Article Synopsis
  • The study investigates how specific microRNAs (miRNAs) affect progesterone resistance in endometriosis patients.
  • It analyzed samples from 18 control, eutopic, and ectopic groups using next-generation sequencing and qRT-PCR to assess miRNA and receptor expressions.
  • Key findings showed that certain miRNAs were upregulated in ectopic tissue and that ERα and ERβ expression levels varied, suggesting that miRNAs may contribute to progesterone resistance and could serve as potential biomarkers or therapeutic targets in endometriosis.

Purpose: In preclinical models, glucocorticoid receptor (GR) signaling drives resistance to taxane chemotherapy in multiple solid tumors via upregulation of antiapoptotic pathways. ORIC-101 is a potent and selective GR antagonist that was investigated in combination with taxane chemotherapy as an anticancer regimen preclinically and in a phase 1 clinical trial.

Patients And Methods: The ability of ORIC-101 to reverse taxane resistance was assessed in cell lines and xenograft models, and a phase 1 study (NCT03928314) was conducted in patients with advanced solid tumors to determine the dose, safety, and antitumor activity of ORIC-101 with nab-paclitaxel.

Purpose: Healthcare workers (HCWs) wearing personal protective equipment (PPE) experience physiological strain that can impair motor and psychological functions, potentially affecting patient care. We assessed the effects of heat exposure on maximal strength and risk-taking behavior among PPE-wearing HCWs and the efficacy of ice slurry to alleviate adverse effects.

Methods: Seventeen HCWS completed two experimental trials in a crossover design, consuming 5 g·kg -1 of body mass of ambient drink (AMB) or ice slurry (ICE) before donning PPE and undergoing 2 h of simulated decontamination exercise (wet-bulb globe temperature (WBGT): 25.
