Plenty of power-shaped semiconductor nanomaterials have been used to photocatalytically degrade various pollutant wastewater in beakers, but they are difficult to be applied in the practical wastewater that is flowing in river or pipeline. Thus, the key to photocatalytically degrading the flowing wastewater is to develop flexible large-scale filter-membrane with high photocatalytic activity. To address the issue, with carbon fiber cloth (CFC) as the porous substrate and TiO2/Ag3PO4 as ultraviolet/visible (UV/Vis) responsed components, we reported the in-situ growth of TiO2/Ag3PO4 nanojunctions on CFC as filter-membrane-shaped photocatalyst. The resulting CFC/TiO2/Ag3PO4 is composed of CFC whose surface is decorated with TiO2 nanorods (length 1 ± 0.5 μm, diameter 150 ± 50 nm) and Ag3PO4 nanoparticles (diameter 20-100 nm). CFC/TiO2/Ag3PO4 displays a broad absorption region with two edges (~410 and ~510 nm), owing to the bandgaps of TiO2 and Ag3PO4. Under Vis or UV-Vis light illumination, CFC/TiO2/Ag3PO4 (4 × 4 cm2) can efficiently degrade more phenol (80.6%/89.4%), tetracycline (TC, 91.7%/94.2%), rhodamine B (RhB, 98.4%/99.5%) and acid orange 7 (AO7, 97.6%/98.3%) in the beaker than CFC/TiO2 or CFC/Ag3PO4. Especially, CFC/TiO2/Ag3PO4 (diameter ~10 cm) as the filter-membrane was used to construct multiple device for degrading the flowing RhB wastewater. The removal efficiency of RhB increases from 19.6% at the 1st pool to 96.8% at the 8th pool. Therefore, this study brings some insights for purifying organic pollutants in static or flowing wastewater by using filter-membrane-shaped photocatalysts. Modulating the size and dispersion of metal particles is highly desirable in nanocatalysis. Herein highly dispersed ruthenium clusters confined in nitrogen-doped carbon (RuNC) were synthesized by a one-pot pyrolysis of Ru(phen)3 organometallic compounds and glucose. The size of the Ru clusters was finely controlled at a cluster level (1.7 nm) to expose more catalytic active sites. The interaction between the Ru clusters and N species not only facilitated the uniform dispersion, but also prevented the aggregation of Ru clusters. This cluster-level RuNC manifested extraordinary catalytic performance towards the hydrogen evolution reaction (HER) and was comparable to or even better than a commercial Pt/C catalyst in basic and acidic media, respectively. Moreover, based on density functional theory (DFT) calculations, it was demonstrated that the N dopants in the carbon framework efficiently tailored the charge density distribution of the Ru centres and promoted the adsorption of H* on the catalyst, thus contributing to the high catalytic activity. BACKGROUND Problems with gait are common in people with multiple sclerosis (MS), but little is known about pelvis and trunk kinematics, especially in the frontal plane. RESEARCH QUESTION Are pelvis and trunk kinematics in people with MS related to muscle function, spatiotemporal parameters, and gait performance? METHODS In this cross-sectional study, 20 people with MS (Expanded Disability Status Scale 1.5-5.5) and 10 people with comparable age and sex (CTL) underwent threedimensional gait analysis, muscle function assessments (hip and trunk strength and endurance), and gait performance measures (Timed 25-Foot Walk - T25FW, 2-Minute Walk Test - 2MWT). Frontal and sagittal plane pelvis and trunk excursion during the stance period of walking were compared between groups; and in the MS group, associations were determined between kinematic variables, muscle function, spatiotemporal parameters, and gait performance. Epigenetic animal study RESULTS Compared to the CTL group, the MS group had significantly greater sagittal plane trunk and pelvis excursion for both the stronger (p = 0.031) and weaker (p = 0.042) sides; less frontal plane trunk and pelvis excursion for both the stronger (p = 0.008) and weaker (p = 0.024) sides; and more sagittal plane trunk excursion for the stronger side (p = 0.047) during stance phase. There were low-to-moderate correlations in the MS group for sagittal plane pelvis excursion with muscle function (p = 0.019 to 0.030), spatiotemporal parameters (p less then 0.001 to 0.005), and gait performance (p = less then 0.001 to 0.001). Using linear regression, frontal and sagittal plane pelvis excursion were significant predictors of both T25FW and 2MWT, explaining 34 % and 46 % of the variance of each gait performance measure, respectively. SIGNIFICANCE Rehabilitation interventions may consider addressing pelvis movement compensations in order to improve spatiotemporal parameters and gait performance in people with MS. BACKGROUND The purpose of this study was to investigate the normal development of postural control in children aged 2-18 years in Tehran, and to provide normative data of computerized dynamic posturography (CDP) device variables. METHODS The study population included 400 boys and 400 girls aged 2-18 years (eight age groups with 2-year interval) and 100 adults aged 22-25 years. In each age group, 100 people were selected based on the inclusion and exclusion criteria. To evaluate the postural control of the subjects, the sensory organization test (SOT) was performed by using a CDP. RESULTS The results of this study led to the determination and presentation of normative data for the development of postural control in boys, girls and children aged 2-18 years. The results related to the repeatability of data produced by the CDP, thereby showing that this system is highly reliable. The results of an independent t-test also showed that girls across all age groups performed better than boys (p ≤ 0.05). CONCLUSION The results of this study demonstrated a nonlinear trend of natural development of postural control. Overall, according to the results of the present study, it seems that like adults, 14-16 year-old teens are capable of processing, integrating and organizing sensory systems information for postural control. Senecavirus A (SVA), also known as Seneca Valley virus (SVV), is an emerging infectious pathogen which have been detected in swine herds from the Brazil, USA, Colombia, Thailand, Canada and some provinces in China, suggesting an increasing geographic distribution of this novel virus. Here, we isolated and characterized a SVV, designated SVA CH-GX-01-2018, thought to be responsible for typical vesicular lesions on the snouts and hooves of finishing pigs from a swine herds in Guangxi province, China, in August 2018. Phylogenetic analysis and sequence alignment indicated that this SVA CH-GX-01-2018 strain was closely related to the strains isolated in 2017 in Guangdong province, a neighboring province of Guangxi, South China, with 98.6% identity at the genome nucleotide level. Our findings characterized a novel SVV infection in pigs from South China and emphasize the importance of surveillance, reinforcing biosecurity measures and developing vaccines to prevent the spread of this viral pathogen.
