Adenosine relaxes vagina smooth muscle through the cyclic guanosine monophosphate- and cyclic guanosine monophosphate-dependent pathways.

Background: In males, adenosine (ADO) is known to relax penile smooth muscles, although its role in the vagina is not yet fully elucidated.

Aim: This study investigated the effect of ADO on vagina smooth muscle activity, using a validated female Sprague-Dawley rat model.

Methods: Contractility studies, using noradrenaline-precontracted vaginal strips, tested the effects of ADORA1/3 antagonists and ADORA2A/2B antagonists and agonists.

The galectin-3 inhibitor selvigaltin reduces liver inflammation and fibrosis in a high fat diet rabbit model of metabolic-associated steatohepatitis.

Introduction: Galectin-3 is a pro-fibrotic β-galactoside binding lectin highly expressed in fibrotic liver and implicated in hepatic fibrosis. Selvigaltin (previously known as GB1211) is a novel orally active galectin-3 small molecule inhibitor that has high affinity for galectin-3 (human K = 25 nM; rabbit K = 12 nM) and high oral bioavailability in rabbits and man. In this study the efficacy of selvigaltin was investigated in a high fat diet (HFD) rabbit model of metabolic-associated steatohepatitis (MASH).

The regulatory effect of sex steroids on the RhoA/ROCK pathway in the rat distal vagina.

Background: Sex steroids have been demonstrated as important modulators of vaginal function. The RhoA/ROCK calcium-sensitizing pathway plays a role in genital smooth muscle contractile mechanism, but its regulation has never been elucidated.

Aim: This study investigated the sex steroid regulation of the vaginal smooth muscle RhoA/ROCK pathway using a validated animal model.

Testosterone does not affect lower urinary tract symptoms while improving markers of prostatitis in men with benign prostatic hyperplasia: a randomized clinical trial.

Purpose: Benign Prostatic Hyperplasia (BPH) is a result of prostate inflammation, frequently occurring in metabolic syndrome (MetS). Low testosterone is common in MetS. A randomized clinical trial was designed to evaluate if 24 weeks of testosterone therapy (TTh) in BPH men with MetS and low testosterone improve urinary symptoms and prostate inflammation.

Testosterone positively regulates vagina NO-induced relaxation: an experimental study in rats.

Purpose: Female sexual response involves a complex interplay between neurophysiological mechanisms and the nitric oxide (NO)-mediated relaxation of clitoris and vagina. The aim of this study was to evaluate sex steroids regulation of the relaxant pathway in vagina, using a validated animal model.

Methods: Subgroups of OVX Sprague-Dawley rats were treated with 17β-estradiol, testosterone, or testosterone and letrozole, and compared with a group of intact animals.
