Comparisons of tactical and technical performance factors between winners and non-winners in Para Taekwondo: A comprehensive analysis of the 2020 Tokyo Paralympic Games.

This study aims to analyse the differences in tactical and technical elements between winners and non-winners and identify key strategic and technical elements contributing to performance in Para Taekwondo. Notational analysis was used to achieve these objectives, and 78 Para Taekwondo matches (36 men's matches and 42 women's matches) from the 2020 Tokyo Paralympics were analysed. The recorded videos were analysed using Adobe Premiere Pro software (version 24.

Rhizobial oxidized 3-hydroxylbutanoyl glycan-based gelatin hydrogels with enhanced physiochemical properties for pH-responsive drug delivery.

Rhizobial exopolysaccharide (EPS) is an acidic polysaccharide involved in nitrogen fixation-related signal transduction in the rhizosphere, serving as a structural support for biofilms, and protecting against various external environmental stresses. Rhizobial EPS as a hydrogel biomaterial was used for a pH-responsive drug delivery system combing with gelatins. Pure gelatin (GA) hydrogels have limited practical applications due to their poor mechanical strength and poor thermal stability.

A pH-sensitive drug delivery using biodegradable succinoglycan/chitosan hydrogels with synergistic antibacterial activity.

Since succinoglycan (SG) produced by Sinorhizobium meliloti is an anionic polysaccharide having substituents such as succinate and pyruvate groups, a polyelectrolyte composite hydrogel can be made together with chitosan (CS), a cationic polysaccharide. We fabricated polyelectrolyte SG/CS hydrogels using the semi-dissolving acidified sol-gel transfer (SD-A-SGT) method. The hydrogel showed optimized mechanical strength and thermal stability at an SG:CS weight ratio of 3:1.

Comparison of the Clinical Effectiveness Between Infrared Thermography and Electrophysiology Tests in Spinal Intradural Extramedullary Schwannoma.

Objective: Subjective pain is experienced differently by each patient; therefore, modalities that can objectify subjective symptoms are useful. Electrophysiology tests and infrared (IR) thermography can present subjective symptoms in an objective manner. This study aimed to compare the effectiveness of electrophysiology tests and IR thermography in patients with intradural extramedullary (IDEM) schwannoma and statistically analyze the results to verify the positive relationship between the subjective neurologic symptoms and test results.

Enhancing mechanical properties of flash-spun filaments by pressure-induced phase separation control in supercritical high-density polyethylene solution.

Flash-spun nonwoven (FS-NW) is gaining attention in the PPE field due to its excellent barrier and mechanical properties resulting from its non-uniform diameter distribution and unique filament morphology. The unique network structure of flash-spun filaments (FSF) comprising the FS-NW can be controlled by phase separation behavior in the supercritical fluid (SCF) process. This study proposes a simple method to control the microstructure of FSFs by controlling the pressure-induced phase separation (PIPS) process in polymer/SCF solution.

The mitochondrial genome of Nagel (Coleoptera: Lucanidae), a carnivorous lucanid from South Korea.

The complete mitochondrial genome of carnivorous was analyzed prior to a study on evolution of carnivorous pathway within the family. This species' genome had a total length of 18,462 bp (GenBank accession number: OL597607), comprising 36 genes along with 13 protein-coding genes, 21 tRNA genes, two rRNA genes, and an A + T rich region. The nucleotide composition was 37.

pH-Responsive Succinoglycan-Carboxymethyl Cellulose Hydrogels with Highly Improved Mechanical Strength for Controlled Drug Delivery Systems.

Carboxymethyl cellulose (CMC)-based hydrogels are generally superabsorbent and biocompatible, but their low mechanical strength limits their application. To overcome these drawbacks, we used bacterial succinoglycan (SG), a biocompatible natural polysaccharide, as a double crosslinking strategy to produce novel interpenetrating polymer network (IPN) hydrogels in a non-bead form. These new SG/CMC-based IPN hydrogels significantly increased the mechanical strength while maintaining the characteristic superabsorbent property of CMC-based hydrogels.

Electrical percolation threshold of carbon black in a polymer matrix and its application to antistatic fibre.

In this study, using three types of resins (each with unique material properties) as a matrix, and carbon black (CB) as a conductive additive, conductive fibres were fabricated through a melt-spinning process. An examination of the electrical conductivity revealed that a CB/polyethylene terephthalate (PET) composite had a low percolation value of 0.58 wt%, and thus the highest conductivity of the three resin types.

Characteristic signatures of quantum criticality driven by geometrical frustration.

Geometrical frustration describes situations where interactions are incompatible with the lattice geometry and stabilizes exotic phases such as spin liquids. Whether geometrical frustration of magnetic interactions in metals can induce unconventional quantum critical points is an active area of research. We focus on the hexagonal heavy fermion metal CeRhSn, where the Kondo ions are located on distorted kagome planes stacked along the c axis.

The Effectiveness of Early Tracheostomy (within at least 10 Days) in Cervical Spinal Cord Injury Patients.

Objective: This study aimed to determine the optimal time for tracheostomy by evaluating the benefits and safety of early versus late tracheostomy in spinal cord injury (SCI) patients.

Methods: We retrospectively reviewed a total of 254 patients with spinal cord injury. Of them, we selected 21 spinal cord injury patients who required tracheostomy due to long-term mechanical ventilation and analyzed their medical records.

Proteomic analysis of Terminalia chebula extract-dependent changes in human lymphoblastic T cell protein expression.

Terminalia chebula is a native plant from southern Asia to southwestern China that is used in traditional medicine for the treatment of malignant tumors and diabetes. This plant also has antibacterial and immunomodulatory properties. The present study assessed T.

Terminalia chebula extract acts as a potential NF-κB inhibitor in human lymphoblastic T cells.

Terminalia chebula (TC) is native to southern Asia to southwestern China and is used in traditional medicine for the treatment of human ailments including malignant tumors and diabetes. This plant also has antibacterial and immunomodulatory properties. Nuclear factor kappa-light chain-enhancer of activated B cells (NF-κB) is responsible for the expression of numerous genes involved in cell survival, proliferation, angiogenesis, inflammation, invasion and metastasis, among other processes.

Dendritic cell activation by glucan isolated from umbilicaria esculenta.

Background: Lichen-derived glucans have been known to stimulate the functions of immune cells. However, immunostimulatory activity of glucan obtained from edible lichen, Umbilicaria esculenta, has not been reported. Thus we evaluated the phenotype and functional maturation of dendritic cells (DCs) following treatment of extracted glucan (PUE).

Potentiation of ceramide-induced apoptosis by p27kip1 overexpression.

The cyclin-dependent kinase inhibitor p27kip1 (p27) has been implicated in the regulation of cell cycle and apoptosis. Recently, we have demonstrated that ceramide induces apoptotic cell death associated with increase in the level of p27 in HL-60 cells. In the present study, we showed that overexpression of p27 increases ceramide-induced apoptotic cell death in HL-60 cells.
