Patients with spinal cord injury (SCI) usually develop lower urinary tract dysfunctions, including detrusor overactivity which is also known to be a risk factor for upper urinary tract dysfunction. Antimuscarinic agents, such as propiverine, have been used clinically for the treatment of detrusor overactivity. Also, propiverine has been known to possess antagonistic activity against L-type Ca(2+) channels and transient receptor potential vanilloid subtype 1 (TRPV1), in addition to activity against muscarinic receptors...

Phthalate esters (PEs) are easily metabolized and commonly excreted via urine within 24h, therefore their bioaccumulation potential is thought to be rather low. In the present study, we developed a sample preparation combined with a new microextraction method to measure seven PE metabolites in nails. The use of whole nails did not result in significantly different levels compared to powdered nails, which makes the method very fast and user friendly. The method was validated using whole nails showing good accuracy, satisfactory precision and low limits of quantification (2-14ng/g)...

The structure of triclinic disodium hafnium disilicate, Na2HfSi2O7, has been determined by laboratory powder X-ray diffraction and refined by the Rietveld refinement. The structure is a framework made of alternate layers of HfO6 octa-hedra and SiO4 tetra-hedra linked by common O atoms. Sodium atoms are located in the voids of the framework, aligned into tunnels along the [010] direction. Na2HfSi2O7 is isostructural with the parakeldyshite Na2ZrSi2O7 phase.

Ultrasound-guided intralesional injection of mesenchymal stem cells (MSCs) is held as the benchmark for cell delivery in tendonitis. The primary objective of this study was to investigate the immediate cell distribution following intralesional injection of MSCs. Unilateral superficial digital flexor tendon (SDFT) lesions were created in the forelimb of six horses and injected with 10 × 10(6) MSCs labeled with superparamagnetic iron oxide nanoparticles (SPIOs) under ultrasound guidance. Assays were performed to confirm that there were no significant changes in cell viability, proliferation, migration, or trilineage differentiation due to the presence of SPIOs...

PURPOSE: Only 3-28% of patients referred to the urology clinic for hematuria are diagnosed with bladder cancer (BC). Cystoscopies lead to high diagnostic costs and patient burden. Therefore, to improve selection of patients for cystoscopy, reduce costs and over-testing we aimed to validate a recently developed diagnostic urine assay MATERIALS AND METHODS: We included 200 patients from three European countries undergoing cystoscopy for hematuria (n=97 BC, n=103 non-malignant). Voided urine samples were collected prior to cystoscopy...

OBJECTIVE AND INTRODUCTION: Cowper's syringocele is a cystic dilation of the bulbourethral gland duct, initially defined by Maizels et al. in 1983. Although obstructive and non-obstructive types of this rare anomaly are described, clinical symptoms are highly unspecific. Therefore, we report 12 cases of children and young adults diagnosed with Cowper's syringocele to further clarify clinical course, comorbidity and treatment strategies. STUDY DESIGN: We retrospectively collected clinical data of 12 children and young adults from birth to 18...

Nocturnal enuresis (NE) is intermittent involuntary voiding during sleep in a child aged 5 years or more. The study was conducted to compare the effect of using laser acupuncture and medication for the treatment of children with nocturnal enuresis (NE) and evaluation of urodynamic parameter after treatment. A randomized study included 45 children ranged from 5 to 15 years presenting with NE. They were randomized into three equal groups-group A, managed with desmopressin acetate; group B, managed with laser acupuncture; and group C, managed with a combination of laser acupuncture and desmopressin-all groups received behavioral therapy...

Using molecular dynamics simulations, we have explored the effect of asymmetric lipids-specifically those that contain one polyunsaturated (PUFA) and one saturated fatty acid chain-on phase separation in heterogeneous membranes. These lipids are prevalent in neuronal membranes, particularly in synaptic membranes, where the Parkinson's Disease protein α-Synuclein (αS) is found. We have therefore explored the relationship between asymmetric, PUFA-containing lipids, and αS. The simulations show that asymmetric lipids partition to the liquid disordered (Ld) phase of canonical raft mixtures because of the highly disordered PUFA chain...

In highly anisotropic biological tissues such as muscle or tendons, calculating Young's modulus from the shear wave speed (csw) by using shear wave elastography (SWE) involves a complex transversally isotropic rheological model not yet used in common practice. To our knowledge, the effect of muscle anisotropy on csw of intra-muscular lesions has not yet been investigated. The objective of our study was to define the effect of an anisotropic medium on csw of intra-muscular gelatinous inclusions. We conducted a prospective monocentric, in vitro study in order to examine the quantitative and qualitative SWE behavior of a 9-mm gelatinous intra-muscular implant depending on the orientation of the probe relative to the muscle fibers...

BACKGROUND: Glycol ethers (GE) are widely used organic solvents. Despite the potential neurotoxicity of several families of organic solvents, little is known about the impact of GE on the neurodevelopment of infants and children. OBJECTIVES: We investigated the relation between urinary concentrations of GE metabolites in pregnant women and neurocognitive abilities in their 6-year-old children in the PELAGIE mother-child cohort. METHODS: Five GE metabolites were measured in first-void urine samples of 204 French pregnant women in early pregnancy (<19 weeks of gestation)...

We propose a method of determination of the dust particle spatial distribution in dust clouds that form in three-dimensional (3D) complex plasmas under microgravity conditions. The method utilizes the data obtained during the 3D scanning of a cloud, and it provides reasonably good accuracy. Based on this method, we investigate the particle density in a dust cloud realized in gas discharge plasma in the PK-3 Plus setup onboard the International Space Station. We find that the treated dust clouds are both anisotropic and inhomogeneous...

Urinary bladder function consists in the storage and controlled voiding of urine. Translational studies require animal models that match human characteristics, such as Octodon degus, a diurnal rodent. This study aims to characterize the contractility of the detrusor muscle and the morphology and code of the vesical plexus from O. degus. Body temperature was measured by an intra-abdominal sensor, the contractility of detrusor strips was evaluated by isometric tension recording, and the vesical plexus was studied by electrical field stimulation (EFS) and immunofluorescence...
