Angiogenesis is a complex process, which accomplished by reiteration of modules such as sprouting, elongation and bifurcation, that configures branching vascular networks. However, details the individual collective behaviors endothelial cells (ECs) during angiogenic morphogenesis remain largely unknown. Herein, we established time-lapse imaging computer-assisted analysis system quantitatively characterizes in sprouting angiogenesis. Surprisingly, ECs moved backwards forwards, overtaking each...
We performed scanning microbeam small-angle X-ray diffraction (micro-SAXD) experiments, differential calorimetry (DSC) analysis, and optical microscopic observation of palm mid fraction (PMF) crystals in oil-in-water emulsion droplets. The micro-SAXD experiment was by irradiating a synchrotron radiation having an area 5 x microm(2) onto different positions on 50 microm diameter droplet after the crystallization PMF chilling at degrees C. patterns were recorded with two-dimensional (2D)...
Background Exercise efficacy can be determined by muscle swelling confirmed through ultrasound, but this method has not been investigated for the intrinsic foot muscles (IFM). Objective To investigate changes over time in and navicular drop (ND) values after IFM exercises evaluated relationship between ND values. Methods In total, 40 feet (10 men; 10 women) were included. The height (NVH) sitting standing positions four cross-sectional areas (CSAs) measured. Measurements taken pre-exercise,...
Objectives To investigate the relationship between sleep quality and perimenstrual symptoms among Japanese female students. Design Observational, cross-sectional, online survey Setting We used an questionnaire to collate responses from students on symptoms. Participants A total of 298 aged 18–25 years in Japan were included this study. Primary secondary outcome measures The Menstrual Distress Questionnaire (MDQ) was assess severity for three periods—premenstrual, menstrual postmenstrual—and...
Objectives Japanese people are known to get the least amount of sleep in world, and particular, increase deprived young women is a serious problem. Sleep deprivation considered be associated with depression, but factors involved this problem unclear. This study aimed examine association between sociodemographic factors, lifestyle choices, sleep-related characteristics depressive symptoms women. Design Web-based cross-sectional study. Participants We distributed an online survey aiming...
The necessary and optimal physical activity for individuals with spinal cord injury remains unclear, the development of interventions adapted to needs is inadequate. To investigate implications health-related outcomes different levels on injuries. participants comprised 67 individuals, aged 18-65 years, injuries, who resided in Japan. Participants' demographic information was obtained, their activities daily living independence, level, mental health status, lifestyle, social capital were...
Background Recurrent lateral ankle sprains (LAS) with chronic instability (CAI) frequently results in damage to the anterior talofibular ligament (ATFL). Eversion muscle strength is crucial for prevention; however, its relationship ATFL length, an indicator of instability, remains unclear. Objective To investigate and compare length eversion between non-CAI CAI sides. Methods Twenty-five adults (50 feet; 12 males; 13 females) unilateral CAI, voluntarily participated. was measured using...
We report a facile method for the formation of charge-free reverse wormlike micelles in nonionic surfactant/oil system without addition water under ambient conditions. This route involves sucrose dioleate (SDO) to semidilute solutions trioleate (STO) hexadecane. A micelle was possible achieve only with ionic surfactants which and/or salts are fundamentally required induce micellar growth so far. In this contribution, we have shown that less lipophilic surfactant SDO promotes one-dimensional...
Crosstalk between microtubules and actin filaments is crucial for various cellular functions, including cell migration, spreading cytokinesis. The Rac1 GTPase plays a key role in such crosstalk at the leading edge of migrating cells order to promote lamellipodial formation. However, mechanism underlying link activation remains unclear. Here, we show that calpain-6 (CAPN6), non-proteolytic calpain with microtubule-binding -stabilizing activity, might participate this crosstalk. Small...
The concentrations of booster compounds were surveyed in the port Osaka, Japan. Sea-Nine 211, Diuron and Irgarol 1051 water samples from Osaka ranges <0·30–0·55 ng l −1 , 13–350 1·3–77 respectively. Pyrithiones not detected samples. levels high mooring area for small medium-hull vessels with poor flushing. Susceptibility bacterial populations estuarine to antifouling biocides was studied. Diuron, Copper pyrithione dissolved dimethyl sulfoxide (DMSO) added number colony forming units (CFU)...
Angiogenesis is a multicellular phenomenon driven by morphogenetic cell movements. We recently reported vascular endothelial (EC) behaviors to be dynamic and complex. However, the principal mechanisms orchestrating individual EC movements in angiogenic morphogenesis remain largely unknown. Here we present an experiment-driven mathematical model that enables us systematically dissect cellular branch elongation. found cell-autonomous coordinated actions governed these behaviors, process...
Vaccinations may be one of the solutions to end COVID-19 pandemic. One's psychological state strongly related one's willingness vaccinated. This study investigated relationship between Japanese university students and their A self-report questionnaire on COVID-19, its vaccines (vaccination status, perceived efficacy safety), (anxiety depressive mood) was administered online, 560 valid responses were obtained. The unvaccinated group reported significantly lower vaccine effectiveness...

Background: Foot malalignment can augment the risk of lower-extremity injuries and lead to musculoskeletal disorders. This study aimed clarify contribution rearfoot alignment plantar pressure distribution spatiotemporal parameters during gait in healthy adolescent athletes. Methods: retrospective included 39 athletes who were divided into eversion control groups according a leg heel angle 7°. A total 78 legs analyzed (45 33 [women, 53.3%] 48.5%], respectively). Gait was assessed using an...
The polarity of GaN films grown on nitrided (0001) sapphire substrates by low-pressure metalorganic vapor phase epitaxy was controlled trymethyl–aluminum (TMAl) preflow prior to the growth buffer layer. TMAl served as forming a few monolayers Al modify surface. effects epilayer polarities were investigated coaxial impact collision ion scattering spectroscopy. It shown that, increasing time, epilayers changed from N mixed polarity, and finally pure Ga when time over than 5 s. A schematic...
Objectives: To evaluate the 'One Stretch' exercise's effect on improvements in low back pain (LBP), psychological factors, and fear avoidance a large number of nurses. Methods: Between July 2015 June 2016, we performed prospective, randomized, parallel-group, multi-center study with central evaluations. Eligible patients were randomly assigned (1:1:1 ratio) to either control group (Group A) or an intervention B: 30-min seminar about exercise, Group C: B + physical approaches LBP treatment)....
Background and Objectives: The effectiveness of multiple ultrasound evaluations the peroneus muscles morphology, including muscle cross-sectional area (CSA) connective tissue, after lateral ankle sprain (LAS) is unknown.
