Academic stakeholders showed top interest in disorders of the metabolism, anti-infectives, and skeletal and dermatological diseases. Although medicinal preparation claims dominated our dataset, a third of patents claimed food preparations, while only 1% claimed application as a diagnostic. Finally, China is, by an inordinate margin, a market of particular interest for both domestic and foreign innovators, indicating that microbiome targeting intervention innovation for EU and US markets might be frustrated. This study is the first to empirically demonstrate that live biotherapeutic product innovation is decelerating and potentially frustrated, supporting the urgent need for improved regulatory standards. Our results indicate which disease areas deserve particular attention for research funding to facilitate proper regulatory appraisal in the near- to mid-term future.
The aim of this study is to examine the functional outcomes of ona-botulinum toxin A (BTX-A) injection into the external urethral sphincter (EUS) for female patients with nonneurogenic nonrelaxing sphincter as the underlying cause of voiding dysfunction (VD).
A retrospective analysis was performed for all the patients with the urodynamic findings of higher than expected maximum urethral closure pressure (MUCP) who received their first injection during the study period. All patients were evaluated with preoperative videourodynamic study and urethral pressure profilometry and received 100 U of EUS BTX-A. Patients aged less than 18 years and those with neurogenic bladder were excluded. All patients were followed up with the free flow, postvoid residuals (PVR), and patient global impression of improvement (PGI-I) scale at 6 weeks and then at 3 monthly intervals.
We identified 35 female patients with a mean age of 37.5 ± 15 years (range 18-72 years) with a mean follow-up of 20 months. More than 50% of patieninary incontinence (for<6 weeks) and there were no significant long-lasting adverse events.
EUS BTX-A is a valid treatment option for VD considering therapeutic options are limited. The patient must be made aware of the need for repeat treatments.

The removal of Pb(II) from aqueous environment is an extremely essential topic due to acquiring clean water resources and its significant impact on human health. Adsorption is an effective and the most widely used method for heavy metal removal from an aqueous medium. Nanofibers have potential advantages in the adsorption of heavy metal ions from wastewater. In this study, nanofibers based on polyvinyl alcohol (PVA) were fabricated for the removal of lead ions from aqueous samples. Nanofibers produced by electrospinning were characterized by scanning electron microscopy (SEM/EDX) and Fourier transform infrared (FT-IR) techniques. A batch system was used for the adsorption of Pb(II) ions onto cross-linked PVA (%10) and PVA (%10)MSs (%2) (Malva Sylestris L. seed biomaterial) nanofibers. The effectiveness of cross-linking was determined by the water absorbency test. The pH, adsorbent amount, adsorption kinetics, isotherms, and thermodynamic values were thoroughly investigated in the adsorption tests. Pb(II) adsorption on the polymer was confirmed by EDX analysis. The optimum values found were a pH of 6, an adsorbent dose of 5.0 mg, and a contact time of 120 min. selleck kinase inhibitor Lead ion concentrations were determined by flame atomic absorption spectrometry (FAAS). The Freundlich models could explain the results from the adsorption data. Similar results were obtained from adsorption isotherm models, and the results were found to support each other. The adsorption capacity for PVA (10%) and PVA (10%)MSs (2%) nanofibers were found to be 444.2 mg g-1 and 588.2 mg g-1, respectively. The adsorption capacity increases with the addition of MSs (2%) biomaterial. As a result, nanofibers can be used as effective adsorbents in the removal of Pb(II) ions. The developed methods are environmentally friendly and promising for the separation of toxic Pb(II) ions from aqueous systems, which is a major problem for environmental pollution.
The urinary bladder is a mechanosensitive organ that accumulates, stores, and expels considerable amounts of fluid. While the neuronal bladder control via the CNS is well defined, the data on the mechanisms of local mechanical sensitivity of the bladder wall are either insufficient or contradictory. Here we compared the mechanical properties of bladder wall of normal rats and rats with modeled type 2 diabetes (T2D).
T2D was modeled in 3-month-old Wistar male rats by combined administration of nicotinamide (230 mg/kg) and streptozotocin (65 mg/kg). Cystometry of isolated, denervated whole bladders and stress-strain tensiometry on detrusor smooth muscle (DSM) strips were used to assess the mechanical properties of bladder wall tissues from control and diabetic animals on 10th week after induction.
The pressure-volume cystometrograms of both control and T2D bladders featured a quasi plateau between ascending sections. T2D cystometrograms revealed markedly elevated intravesicular pressure (~100% at 1 ml) and a shortened plateau, consistent with decreased bladder wall elasticity and reduced structural bladder capacity versus control. Experiments on urothelium-intact and urothelium-devoid DSM strips have shown that the decrease of bladder walls elasticity in T2D can be explained by the switch of stretched urothelium from inducing DSM relaxation to inducing DSM contraction due to a change in the prevalent release of contractile versus relaxing urothelial factor(s).
The decreased elasticity of the bladder walls in T2D results from alterations in urothelium-dependent mechanosensory mechanisms. Elevated intravesical pressure in T2D may contribute to urge incontinence and/or symptoms of upper urinary tract damage.

The aim was to examine associations of specific anxiety disorders, depressive symptoms, and incontinence in a representative, population-based sample of preschool children.
All preschool children of a defined geographical area examined before school-entry were included. Parents completed a questionnaire including the Preschool Feelings Checklist (PFC), eight questions referring to nocturnal enuresis (NE), daytime urinary incontinence (DUI), fecal incontinence (FI) and constipation, and 30 items regarding Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (DSM-5) diagnostic criteria of separation anxiety disorder (SAD), social phobia (SOC), specific phobia (PHOB), and generalized anxiety disorder (GAD). Data of 1206 children (mean age = 5.7 years; 53.5% boys) are presented.
34.6% of incontinent children had an anxiety disorder based on DSM-5 criteria and 13.3% had clinically relevant depressive symptoms (measured by the PFC). Rates of incontinence overall were 14.1% (11.9% NE, 3.1% DUI, rates of anxiety disorders, it is important to screen all children with incontinence, for example, with specific questionnaires.
In this study, the combination of external electrical stimulation (EES) with pelvic floor muscle training (PFMT) was assessed to determine if it yielded better results than PFMT or EES alone for treatment of stress urinary incontinence (SUI).
Fifty-one women with SUI were randomly allocated to EES + PFMT (n = 17), PFMT (n = 17), or EES groups (n = 17) for 8 weeks of treatment. Personal, demographic, and clinical characteristics of the patients were recorded. Outcome measures included self-reported improvement, severity of incontinence, symptom distress, quality of life (QOL), urinary incontinence episodes, pelvic floor muscle strength (PFMS) and endurance (PFME) and dysfunction. All evaluations were made pre- and posttreatment. Data were analyzed using the Chi-square, marginal homogeneity, Kruskal-Wallis, Wilcoxon signed-rank or paired t test and Dunn-Bonferroni post hoc tests.
In the 8th week, there were significant changes in self-reported improvement, severity of incontinence, symptom distress score, urinary incontinence episodes, PFMS, PFME, pelvic floor dysfunction and all areas of QoL in all groups (p < 0.05). Combined therapy was not superior to PFMT and EES for overall outcome measures, except for the incontinence impact subdomain of the QoL score (p < 0.05).
Our study supports the idea that PFMT should be preferred as the first line therapy for women with SUI. However, the acceptable EES method can be recommended in addition to PFMT to increase motivation and treatment compliance in patients with insufficient or inaccurate pelvic floor muscle contractions.

To establish age-related, normal limits of monocular and binocular spatial vision under photopic and mesopic conditions.
Photopic and mesopic visual acuity (VA) and contrast thresholds (CTs) were measured with both positive and negative contrast optotypes under binocular and monocular viewing conditions using the Acuity-Plus (AP) test. The experiments were carried out on participants (age range from 10 to 86 years), who met pre-established, normal sight criteria. Mean and ± 2.5σ limits were calculated within each 5-year subgroup. A biologically meaningful model was then fitted to predict mean values and upper and lower threshold limits for VA and CT as a function of age. The best-fit model parameters describe normal aging of spatial vision for each of the 16 experimental conditions investigated.
Out of the 382 participants recruited for this study, 285 participants passed the selection criteria for normal aging. Log transforms were applied to ensure approximate normal distributions. Outliers were also rision for monocular and binocular viewing under photopic and high mesopic lighting with both positive and negative contrast optotypes using a single test, which can be implemented either in the clinic or in an occupational setting.Directional droplet-sliding control without wetting the surface is immensely required in advanced surface engineering, including biological and chemical analyses or green technology. However, the development of robust and transparent thin sticker-type directional omniphobic films for portable usage in smart microfluidic platforms is rare. In this study, we report a novel perfluoropolyether (PFPE) directional omniphobic film (PDOF). The PDOF is a robust and transparent ultra-thin sticker-type film that can control the anisotropic sliding of various liquid droplets on the surface. The PFPE is a chemically stable and turgid material compared to polydimethylsiloxane (PDMS), which is often used to fabricate liquid-repellent thin films. A well-designed fabrication criterion through adhesion engineering in the soft-molding process was developed using the PFPE to obtain a PDOF with a thickness of 56 μm, with re-entrant micro-stripe structures on the surface. The fabricated PDOF showed intriguing liquid sliding properties based on the direction and spacing of the microstructures.
