[Conclusion] Depression, reduced pulmonary function, and reduced deglutition ability were independently related to low QOL. Assessment of these factors could be beneficial for maintaining the physical and mental components of QOL in community-dwelling frail older persons in long-term care.[Purpose] The purpose of this study was to determine whether unilateral dominance exists in toe grip strength in Kendo players using a toe grip dynamometer. [Participants and Methods] In total, 15 male college Kendo players, who had no disability or pain in their feet, were included in the study. The participants completed a questionnaire to determine which foot the participants used as their front and rear foot while standing in Kendo. We measured toe grip strength three times on each side. We then extracted the maximum value of toe grip strength from the three measurements on each side and calculated the ratio of toe grip strength to body weight (%). [Results] All players used their right foot as the front foot. We found that the front foot toe grip strength was significantly stronger than the rear foot toe grip strength. [Conclusion] Our results suggest laterality of toe grip strength and the front foot toe grip strength is stronger than the rear foot toe grip strength in Kendo players.[Purpose] The aim of this study was to determine if gait index predicts the efficacy of weight-support treadmill training (BWSTT) in hemiplegic stroke patients. [Participants and Methods] In total, 21 patients who had sustained a hemiplegic stroke, on an average 71 days prior, and could walk independently on level ground were included in the study. BWSTT was performed under 20% of bodyweight unloading at the maximum speed possible for each participant to a perceived level of fatigue of 15 on the 20-point Borg scale. The immediate effects of BWSTT were evaluated as the change in the following variables, calculated from 5 level ground gait cycles; walking speed and rate, root mean square, coefficient of variability, auto-correlation coefficient, and single leg stance time ratio. All indices were calculated from the triaxial accelerometer attached to the waist of the participant. Linear regression was used to identify predictive variables of BWSTT effectiveness. [Results] Only single leg stance time ratio on level ground was extracted as a predictor of BWSTT effectiveness. [Conclusion] Single leg stance time ratio was a predictive factor of improved gait symmetry after BWSTT and therefore, could be used as a factor to select patients who might benefit from BWSTT as a component of stroke rehabilitation.Vertically aligned nanocomposite (VAN) films, comprising nanopillars of one phase embedded in a matrix of another, have shown great promise for a range of applications due to their high interfacial areas oriented perpendicular to the substrate. In particular, oxide VANs show enhanced oxide-ion conductivity in directions that are orthogonal to those found in more conventional thin-film heterostructures; however, the structure of the interfaces and its influence on conductivity remain unclear. In this work, 17O NMR spectroscopy is used to study CeO2-SrTiO3 VAN thin films selective isotopic enrichment is combined with a lift-off technique to remove the substrate, facilitating detection of the 17O NMR signal from single atomic layer interfaces. By performing the isotopic enrichment at variable temperatures, the superior oxide-ion conductivity of the VAN films compared to the bulk materials is shown to arise from enhanced oxygen mobility at this interface; oxygen motion at the interface is further identified from 17O relaxometry experiments. The structure of this interface is solved by calculating the NMR parameters using density functional theory combined with random structure searching, allowing the chemistry underpinning the enhanced oxide-ion transport to be proposed. Finally, a comparison is made with 1% Gd-doped CeO2-SrTiO3 VAN films, for which greater NMR signal can be obtained due to paramagnetic relaxation enhancement, while the relative oxide-ion conductivities of the phases remain similar. These results highlight the information that can be obtained on interfacial structure and dynamics with solid-state NMR spectroscopy, in this and other nanostructured systems, our methodology being generally applicable to overcome sensitivity limitations in thin-film studies.Metal sulfide and metal oxide alloys of the form Mo1-x W x S2 and Mo1-x W x O3 (0 ≤ x ≤ 1) are synthesized with varying nominal stoichiometries (x = 0, 0.25, 0.50, 0.75, and 1.0) by thermolysis of the molecular precursors MoL4 and WS(S2)L2 (where L = S2CNEt2) in tandem and in various ratios. Either transition-metal dichalcogenides or transition-metal oxides can be produced from the same pair of precursors by the choice of reaction conditions; metal sulfide alloys of the form Mo1-x W x S2 are produced in an argon atmosphere, while the corresponding metal oxide alloys Mo1-x W x O3 are produced in air, both under atmospheric pressure at 450 °C and for only 1 h. Changes in Raman spectra and in powder X-ray diffraction patterns are observed across the series of alloys, which confirm that alloying is successful in the bulk materials. [https://www.selleckchem.com/products/ins018-055-ism001-055.html selleck chemical] For the oxide materials, we show that the relatively complicated diffraction patterns are a result of differences in the tilt angle of MO6 octahedra within three closely related unit cell types. Alloying of Mo and W in the products is characterized at the microscale and nanoscale by scanning electron microscopy-energy-dispersive X-ray spectroscopy (EDX) and scanning transmission electron microscopy-EDX spectroscopy, respectively.We combine spatially resolved scanning photoelectron spectroscopy with confocal Raman and optical microscopy to reveal how the oxidation of the buried graphene-Cu interface relates to the Cu crystallographic orientation. We analyze over 100 different graphene covered Cu (high and low index) orientations exposed to air for 2 years. Four general oxidation modes are observed that can be mapped as regions onto the polar plot of Cu surface orientations. These modes are (1) complete, (2) irregular, (3) inhibited, and (4) enhanced wrinkle interface oxidation. We present a comprehensive characterization of these modes, consider the underlying mechanisms, compare air and water mediated oxidation, and discuss this in the context of the diverse prior literature in this area. This understanding incorporates effects from across the wide parameter space of 2D material interface engineering, relevant to key challenges in their emerging applications, ranging from scalable transfer to electronic contacts, encapsulation, and corrosion protection.
