Background: Primary amoebic meningoencephalitis (PAM), caused by Naegleria fowleri, poses a significant challenge in humans owing to its high mortality rate, exceeding 97 %. Current therapeutics have been unable to deliver satisfactory treatment outcomes, due to suboptimal efficacy and toxicity, highlighting the critical need for efficacious drug development. In this study, we identified a natural compound, 3,5-Dihydroxy-8‑methoxy-1-O-β-d-glucopyranosyl xanthone (DX), which exhibited promising anti-N.

However, commutability assessment is not routinely performed. We assessed whether RMs prepared following CLSI C37-A guidelines could be used without assessing commutability by evaluating their commutability for four lipid measurements using the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) and CLSI EP14 protocols.

Whole-body kinematics of 20 male participants performing simulated crab sorting were collected and integrated into a human-BSE interaction simulation framework to predict muscle activity, spinal loads, and contact forces at the human-BSE interfaces. Increasing the BSE support level generally reduced trunk extensor muscle activity (up to 28.

Background: Fishing is a physically demanding occupation with a high risk of musculoskeletal disabilities (MSDs). Although previous studies have focused on ergonomic risk factors, little attention has been paid to sex differences in the prevalence of MSDs among fishers. This study aimed to assess whether female fishers experience a higher prevalence of MSDs than male fishers and to examine whether this difference persists after adjusting for socioeconomic and occupational factors.

This study aimed to evaluate the bioactivities of GSs cultivated using kelp fermentates (KF) as a nutrient solution under a smart-farming system. Ginsenoside-enriched extract (FGE), its water-soluble saponin fraction (WFGE), and 70% ethanol-soluble saponin fraction (EFGE) were analyzed for phytochemical contents and biological activities.

Substantial trunk flexion and associated low back loads during crab sorting tasks have been attributed to awkward sorting table heights. This study examined how varying table heights affect biomechanical loads on the low back and shoulders.

Lattice structures, composed of interconnected struts, offer an efficient way to reduce structural weight while maintaining structural integrity. Because of this potential, this work aims to investigate and develop an efficient variant form of a BCC (Body-Centered Cubic) lattice structure to enhance the structural robustness and energy absorption capability, based on the Maxwell stability criterion. And we specifically changed the bending-dominated to stretching-dominated behavior by adding auxiliary struts, according to the theory, and confirmed how this affects the compression behavior of the structure.

Parameter optimization to minimize the degradation of mechanical properties due to the expanded particle size distribution was conducted. Mechanical tests for specimens built using optimized parameters revealed minor reductions in strength: 3.

For the diagnosis of GHD and ISS, meticulous evaluations are required, including growth hormone provocation tests, which are invasive and burdensome for children. Additionally, sella magnetic resonance imaging (MRI) is necessary for assessing etiologies of GHD, which cannot evaluate hormonal secretion.

Consequently, fishermen must reach outside the vessel to grab the pots, posing increased risk of musculoskeletal and fall-related injuries. To investigate the effects of block design on these risks, 25 participants in a repeated-measures laboratory study handled a pot under two block conditions: away-from-table (conventional setting) and above-table (intervention).

Fasiglifam, a candidate targeting GPR40, showed efficacy in clinical trials for type 2 diabetes but exerted liver toxicity. This study investigated the drug-induced liver injury (DILI) risk of Xelaglifam, a new GPR40 agonist, based on the potential toxicity mechanism of Fasiglifam; transporter inhibition, mitochondrial dysfunction, reactive metabolite formation, and covalent binding to proteins. In the hepatobiliary transporter assay, Xelaglifam showed a broader safety margin (>10-fold) against bile acid transporters, suggesting its less likelihood to cause bile acids accumulation, unlike Fasiglifam (<10-fold safety margin).

We present a case of iatrogenic iliac vein rupture with venous thrombosis during total hip arthroplasty that was endovascularly treated with the insertion of covered and uncovered stents, aspiration, and balloon maceration of the thrombus. We describe in detail, with a schematic diagram, an endovascular treatment method that can be performed under local anesthesia alone and explain how to overcome the situation when the diameter of the covered stent is inadequate to cover the iliac vein.

In this report, we present a case of a radiotherapy-induced tracheoesophageal fistula treated with the fluoroscopy-guided insertion of a covered stent through the gastrostomy route using both the antegrade and retrograde approaches. The initial antegrade endoscopic and fluoroscopic stent insertion procedure failed due to severe esophageal stricture. Compared to the endoscopic approaches, fluoroscopy-guided radiologic procedures are generally less invasive and more successful because they allow for a better understanding of the anatomy outside the lumen during the procedure and enable the use of devices with smaller diameters.

However, the reliability of the feedback current value, core sensing data, is reduced when welding target workpieces have significant curvature or gaps between curved workpieces due to the control of short-circuit transition, leading to seam tracking failure and subsequent damage to the workpieces. To address these problems, this study proposes a new algorithm, MBSC (median-based spatial clustering), based on the DBSCAN (density-based spatial clustering of applications with noise) clustering algorithm.

The GSRs consist of a 12-transmembrane glucose recognition domain and a cytoplasmic C-terminal signaling tail. The GSR tails are dissimilar in length and sequence, but their distinct roles in glucose signal transduction are poorly understood.
