Understanding the dietary composition of the Siberian musk deer () is critical for informing conservation efforts, particularly given the species' vulnerable status in the Republic of Korea and its limited ecological data. Previous dietary studies have relied on conventional methods with limitations in taxonomic precision, hindering comprehensive insights into their feeding ecology. To address this gap, we used Next-Generation Sequencing to analyze 16 fecal samples collected in April from Gangwon Province, the habitat of .

Golgi abnormalities have been linked to aging and age-related diseases, yet the underlying causes and functional consequences remain poorly understood. This study identifies the interaction between age-associated zinc deficiency and Golgi stress as a critical factor in cellular aging. Senescent Golgi bodies from human fibroblasts show a fragmented Golgi structure, associated with a decreased interaction of the zinc-dependent Golgi-stacking protein complex Golgin45-GRASP55.

Novel silicone-modified biochar adsorbents (BPS-MBCs) were prepared by utilizing waste black peanut shell (BPS) as a raw biochar and gamma-amino-propyl triethoxysilane (silicone) as an inorganic modifier. The novelty of this work is that the incorporation of silicone into BPS can rise the specific surface area and porosity of BPS-MBCs and elevate their adsorptions for copper (II). Sorption kinetics data for copper (II) were molded using five kinetic equations [i.

Background: Handgrip strength (HGS) and psoas muscle index (PMI) are widely used protocols for screening or diagnosing sarcopenia by measuring muscle strength and mass. Epidural steroid injection (ESI) is a common intervention for the treatment of spinal pain; however, the influence of pre-procedural sarcopenic status on therapeutic effects after ESI has not been investigated.

Objectives: In the present study, whether pre-procedural HGS or PMI predicts analgesic efficacy of ESI in elderly patients with degenerative lumbar spinal disease was investigated.

The relationship between sarcopenia and pain remains unclear; thus, this study evaluated whether muscle strength is independently associated with neuropathic-like pain symptoms in patients with chronic musculoskeletal pain. A cut-off score of painDETECT ≥13 was used to indicate a possible neuropathic component. Handgrip strength was measured, and muscle mass was estimated.

A facile stamping method was developed to assemble ordered arrays of mesoporous WO micropillars with uniform sizes, shapes, and lengths on F-doped tin oxide glass. Using this method, a series of WO heterostructural bilayer photoanodes consisting of an array of -μm long ordered mesoporous WO micropillars at the top and the -μm thick mesoporous WO plain sheet layer at the bottom (denoted as ) were prepared. Among them 2.

Background: An assessment of paraspinal muscle degeneration based on magnetic resonance imaging has been used to investigate both sarcopenia and myosteatosis. The morphologic changes in cross-sectional area and fat infiltration of the paraspinal muscles can affect pain outcomes after epidural steroid injection.

Methods: Patients ≥65 years of age who underwent fluoroscopy-guided lumbar epidural steroid injections were enrolled.

Zeolites are 3D aluminosilicate materials having subnanometer pore channels. The Lewis basic pores have charge-balancing cations, easily tuned to metallic ions as more chemically active sites. Among the ion-exchanged zeolites, Cu ion-exchanged ZSM-5 (Cu-ZSM-5) is one of the most active zeolites with chemical interactions of Lewis basic compounds.

In this study, the performance evaluation was performed by adding a polymer aqueous (PA) solution as a new additive of the red clay binder for use in the rammed-earth construction method. The evaluation items were compressive strength, water erosion, shrinkage, crystal structure, and microstructure. As a result of the experiment, the binder was improved by efficiently bonding the silica particles by the polymerized polymer.

Zeolites are three-dimensional aluminosilicates having unique properties from the size and connectivity of their sub-nanometer pores, the Si/Al ratio of the anionic framework, and the charge-balancing cations. The inhomogeneous distribution of the cations affects their catalytic performances because it influences the intra-crystalline diffusion rates of the reactants and products. However, the structural deformation regarding inhomogeneous active regions during the catalysis is not yet observed by conventional analytical tools.

The datasets included sequences of a control region from bat mitogenomes. The control region (1706-2005 bp) of the mitogenomes was divided into three domains similar to that of other mammals, which included the common conserved blocks (ETAS domain, Central domain, and CSB domain). Several long tandem repeat sequences were present between the upstream of control regions and ETAS1.
