Brain Responses Difference between Sexes for Strong Desire to Void: A Functional Magnetic Resonance Imaging Study in Adults Based on Graph Theory.

The alternations of brain responses to a strong desire to void were unclear, and the gender differences under the strong desire to void remain controversial. The present study aims to identify the functional brain network's topologic property changes evoked by a strong desire to void in healthy male and female adults with synchronous urodynamics using a graph theory analysis. The bladders of eleven healthy males and eleven females were filled via a catheter using a specific infusion and withdrawal pattern.

Subjects were assessed via bladder diaries, postvoid residual volumes (PRVs) and neurogenic bowel dysfunction (NBD) scores before and during the testing period.

Brain functional network alterations caused by a strong desire to void in healthy adults: a graph theory analysis study.

Purpose: This resting-state functional magnetic resonance imaging (fMRI) study determined the functional connectivity (FC) changes and topologic property alterations of the brain functional network provoked by a strong desire to void in healthy adults using a graph theory analysis (GTA).

Materials And Methods: Thirty-four healthy, right-handed subjects filled their bladders by drinking water. The subjects were scanned under an empty bladder and a strong desire to void states.

[Application and progress of neuromodulation in lower urinary tract dysfunction].

For those patients with refractory lower urinary tract dysfunction who are not well treated by traditional therapy such as behavior therapy and drug therapy, neuromodulation technologies have gradually become alternative treatments. Several neuromodulation technologies are also used in animal experimental and clinical scientific research by more and more scholars, in order to find more effective methods and mechanisms of treatment of lower urinary tract dysfunction. This article introduces the principle and advantages of common neuromodulation technologies, which focuses on the application in lower urinary tract dysfunction treatment, and analyzes the direction and the broad prospect of neuromodulation.

Urodynamic findings during the filling phase in neurogenic bladder patients with or without vesicoureteral reflux who have undergone sacral neuromodulation.

Aims: To assess the urodynamic findings during the filling phase in neurogenic bladder patients with or without vesicoureteral reflux (VUR) who underwent sacral neuromodulation (SNM).

Methods: We retrospectively reviewed the records of 19 patients with neurogenic lower urinary tract dysfunction (NLUTD) who underwent SNM at our center from July 2018 to July 2019. Clinical data and video-urodynamic parameters were collected.

Calycosin Influences the Metabolism of Five Probe Drugs in Rats.

Background: Calycosin (CAL), a type of O-methylated isoflavone extracted from the herb (AM), is a bioactive chemical with antioxidative, antiphlogistic and antineoplastic activities commonly used in traditional alternative Chinese medicine. AM has been shown to confer health benefits as an adjuvant in the treatment of a variety of diseases.

Aim: The main objective of this study was to determine whether CAL influences the cytochrome P450 (CYP450) system involved in drug metabolism.

Tetrandrine Ameliorates Airway Remodeling of Chronic Asthma by Interfering TGF-1/Nrf-2/HO-1 Signaling Pathway-Mediated Oxidative Stress.

Background: Imbalanced oxidative stress and antioxidant defense are involved in airway remodeling in asthma. It has been demonstrated that Tetrandrine has a potent role in antioxidant defense in rheumatoid arthritis and hypertension. However, the correlation between Tetrandrine and oxidative stress in asthma is utterly blurry.

Evaluation of lentinan effects on cytochrome P450 activity in rats by a cocktail method.

Objectives: In this study, a cocktail of probe drugs was used to assess whether lentinan could influence the activities of rat enzymes CYP3A4, CYP2D6, CYP1A2, CYP2C19, and CYP2C9 in vivo.

Materials And Methods: Fourteen days after intraperitoneal injection of lentinan, rats were given an oral dose of a cocktail solution containing phenacetin, tolbutamide, omeprazole, metoprolol, and midazolam. Then, we obtained blood in specific durations for the determination of plasma concentration of the probe drugs using UPLC-MS/MS.

Endoplasmic reticulum protein 29 (ERp29), a protein related to sperm maturation is involved in sperm-oocyte fusion in mouse.

Background: Sperm-oocyte fusion is a critical step in fertilization, which requires a series of proteins from both spermatozoa and oocyte to mediate membrane adhesion and subsequent fusion. A rat spermatozoa membrane protein is endoplasmic reticulum protein 29 (ERp29), which significantly increases on the sperm surface as well as in the cytoplasm of epididymal epithelia from caput to cauda as the sperm undergo epididymal maturation. Moreover, ERp29 facilitates viral infection via mediating membrane penetration.

The role of Zn-alpha2 glycoprotein in sperm motility is mediated by changes in cyclic AMP.

Sperm motility is essential for male reproduction or natural fertilization. The cyclic AMP (cAMP)/cAMP-dependent protein kinase A (PKA) signaling pathway is generally recognized as one of the significant signaling pathways in the regulation of mammalian spermatozoan motility. Since Zn-alpha2-glycoprotein (ZAG) activity in mammalian adipose tissue is mediated via the beta(3)-adrenoreceptor, with upregulation of the cAMP pathway, we hypothesize that ZAG may play the same role in sperm motility regulation, a new factor of regulation of sperm motility.

Identification of sperm forward motility-related proteins in human seminal plasma.

Seminal plasma, an amorphous material that exists in semen, contains proteins related to sperm forward motility. Employing affinity chromatography with ConA beads and protein ultrafiltration, we isolated and concentrated proteins from heated human seminal plasma. Results of computer-assisted semen analyses (CASA) demonstrated that the forward motility index of bovine spermatozoa from the epididymal caput, incubated with proteins and theophylline, was significantly different from that of spermatozoa incubated with theophylline alone (P < 0.

Identification and characterization of ERp29 in rat spermatozoa during epididymal transit.

The mammalian epididymis is able to create sequential changes in the composition of luminal fluid throughout its length, wherein spermatozoa undergo morphological, biochemical, and physiological modifications. Subsequently, spermatozoa acquire the ability for fertilization upon reaching the epididymal cauda. In this study, protein variations in Sprague-Dawley rat spermatozoa along the caput and caudal regions of epididymis were investigated by high-resolution two-dimensional gel electrophoresis (2DE) in combination with mass spectrometry.
