Multi-trait Genome-Wide Analysis Identified 20 Novel Loci for Sarcopenia-Related Traits in UK Biobank.

This study aims to identify novel loci associated with sarcopenia-related traits in UK Biobank (UKB) through multi-trait genome-wide analysis. To identify novel loci associated with sarcopenia, we integrated the genome-wide association studies (GWAS) of usual walking pace (UWP) and hand grip strength (HGS) to conduct a joint association study known as multi-trait analysis of GWAS (MTAG). We performed a transcriptome-wide association study (TWAS) to analyze the results of MTAG in relation to mRNA expression data for genes identified in skeletal muscle.

Attenuating Atherosclerosis through Inhibition of the NF-B/NLRP3/IL-1 Pathway-Mediated Pyroptosis in Vascular Smooth Muscle Cells (VSMCs).

Objective: We investigated the effects of resveratrol (Res) and MCC950 on the pyroptosis of vascular smooth muscle cells (VSMCs) and the potential pathway.

Methods And Results: Compared with the control (Con) group, the atherosclerosis (AS) group showed calcified nodules, which suggested that the calcification medium induced the calcification of VSMCs. VSMCs showed proliferative activity and significantly attenuated calcification under treatment with 10 mol/L Res.

Research on correlation analysis and multivariate nonlinear regression modeling method for the tensile properties of mugwort petiole.

The defoliation quality of mugwort defoliation equipment is an important factor to measure the defoliation efficiency, and the tensile properties of mugwort petiole will have an impact on the defoliation quality, such as the crushing rate and the abscission rate. In order to reduce the crushing rate and improve the abscission rate during mechanical harvesting of mugwort leaves, the tensile properties of mugwort petiole need to be studied. The tensile properties of mugwort petiole are closely related to its macroscopic and microscopic physicochemical parameters.

Resolvin D1 combined with exercise rehabilitation alleviates neurological injury in mice with intracranial hemorrhage via the BDNF/TrkB/PI3K/AKT pathway.

Resolvin D1 (RvD1) is an endogenous anti-inflammatory mediator that modulates the inflammatory response and promotes inflammation resolution. RvD1 has demonstrated neuroprotective effects in various central nervous system contexts; however, its role in the pathophysiological processes of intracerebral hemorrhage (ICH) and the potential protective mechanisms when combined with exercise rehabilitation remain unclear. A mouse model of ICH was established using collagenase, and treatment with RvD1 combined with three weeks of exercise rehabilitation significantly improved neurological deficits, muscle strength, learning, and memory in ICH mice while reducing anxiety-like behavior.

Methods: Forty-five patients with MCI and 45 cognitively unimpaired controls (CUCs) were recruited.

Two Hundred Nanometer Thin Multifocal Graphene Oxide Metalens for Varying Magnification Broadband Imaging.

Conventional microscopes, which rely on multiple objective lenses for varying magnifications, are bulky, complex, and costly, making them difficult to integrate into compact devices. They require frequent manual adjustments, complicating the imaging process and increasing maintenance burdens. This paper explores the potential of single ultrathin graphene metalens to address this issue.

Fomesafen induced ecotoxicological responses, bioaccumulation, and implications for soil ecosystems remediation in three ecotypes earthworms.

Fomesafen (FSA) is a herbicide commonly used in soybean fields, but its long half-life in the soil can pose pollution risks to the soil ecosystem. Earthworms, which have an indicative function for soil health and play a vital role in maintaining soil ecological functions, have not been fully studied in terms of their susceptibility to FSA. This study examined the effects of different concentrations of FSA on three ecotypes of earthworms (Eisenia fetida (epigeic), Metaphire guillelmi (anecic), and Aporrectodea caliginosa (endogeic)) and found varying trade-off strategy of their growth and reproduction.

CMFNet: a cross-dimensional modal fusion network for accurate vessel segmentation based on OCTA data.

Optical coherence tomography angiography (OCTA) is a novel non-invasive retinal vessel imaging technique that can display high-resolution 3D vessel structures. The quantitative analysis of retinal vessel morphology plays an important role in the automatic screening and diagnosis of fundus diseases. The existing segmentation methods struggle to effectively use the 3D volume data and 2D projection maps of OCTA images simultaneously, which leads to problems such as discontinuous microvessel segmentation results and deviation of morphological estimation.

Locally manufactured malaria RDTs for Plasmodium vivax: A comparative study of kits approved by National Medical Products Administration in China.

In this study, we aimed to compare the performance of three different commercial malaria rapid diagnostic test (RDT) kits for screening P. vivax in China.

X-ray-induced acoustic computed tomography: 3D X-ray absorption imaging from a single view.

Computed tomography (CT) scanners are essential for modern imaging but require around 600 projections from various angles. We present x-ray-induced acoustic computed tomography (XACT), a method that uses radiation-induced acoustic waves for three-dimensional (3D) x-ray imaging. These spherical acoustic waves travel through tissue at 1.

Inflammatory and Nutritional Markers as Indicators for Diagnosing and Assessing Disease Activity in MS and NMOSD.

Background: Inflammation and nutritional markers have recently gained recognition for their roles in the fabrication of cognitive control centers demyelinating illnesses. Inflammatory indices such as the neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammatory index (SII), and systemic inflammatory response index (SIRI), along with nutritional markers like albumin (ALB), hemoglobin (HB), and body mass index (BMI), may predict disease occurrence. However, their potential in evaluating diseases such as multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) remains unexplored.

Enhanced sludge dewaterability and confined antibiotics degradation in biochar-mediated chemical conditioning through modulating Fe oxidative states distribution and reaction sites in multiphase.

For antibiotic-enriched waste activated sludge, classical iron-based chemical conditioning significantly enhanced sludge dewaterability. Nevertheless, the intricate constituents within sludge rapidly depleted reactive oxygen species (ROS), leading to challenges such as excessive production of iron sludge and inadequate elimination of antibiotics from sludge. Herein, we proposed an innovative strategy integrating biochar with Fe(II) for peroxymonosulfate (PMS) activation, aiming to enhance both sludge dewaterability and antibiotics elimination simultaneously.

PPARγ-dependent remodeling of translational machinery in adipose progenitors is impaired in obesity.

Adipose tissue regulates energy homeostasis and metabolic function, but its adaptability is impaired in obesity. In this study, we investigate the impact of acute PPARγ agonist treatment in obese mice and find significant transcriptional remodeling of cells in the stromal vascular fraction (SVF). Using single-cell RNA sequencing, we profile the SVF of inguinal and epididymal adipose tissue of obese mice following rosiglitazone treatment and find an induction of ribosomal factors in both progenitor and preadipocyte populations, while expression of ribosomal factors is reduced with obesity.

Methods: A total of 258 participants, including 68 patients with Alzheimer's disease (AD), 86 with subcortical ischemic vascular dementia (SIVD), 30 with frontotemporal lobar degeneration (FTLD), 22 with Lewy body dementia (LBD), and 52 cognitively unimpaired (CU) controls, were enrolled from a memory clinic.

Neddylation of protein, a new strategy of protein post-translational modification for targeted treatment of central nervous system diseases.

Neddylation, a type of protein post-translational modification that links the ubiquitin-like protein NEDD8 to substrate proteins, can be involved in various significant cellular processes and generate multiple biological effects. Currently, the best-characterized substrates of neddylation are the Cullin protein family, which is the core subunit of the Cullin-RING E3 ubiquitin ligase complex and controls many important biological processes by promoting ubiquitination and subsequent degradation of various key regulatory proteins. The normal or abnormal process of protein neddylation in the central nervous system can lead to a series of occurrences of normal functions and the development of diseases, providing an attractive, reasonable, and effective targeted therapeutic strategy.

The correlation between fluoride-induced bone damage and reduced DLAV formation in Zebrafish Larvae.

In this study, we aimed to investigate the mechanism by which fluoride exposure causes bone damage and the relationship with the loss of dorsal longitudinal anastomotic vessel (DLAV) formation in zebrafish larvae to further understanding of skeletal fluorosis. We assessed the development of chondrogenesis, osteogenesis, and DLAV angiogenesis, and reactive oxygen species (ROS) in zebrafish larvae subjected to blank control group (Con), low-fluoride group (LF), and high-fluoride group (HF). Abnormal development of the cartilage area, bone mineralization accompanied with abnormal mRNA expression of osteoblast-related OC, ALP, and Runx2b genes and osteoclast-related OPG and RANKL genes, and abnormal DLAV angiogenesis and ROS levels in zebrafish larvae were affected to varying degrees with the increase of fluoride exposure.

1-Deoxynojirimycin affects high glucose-induced pancreatic beta-cell dysfunction through regulating CEBPA expression and AMPK pathway.

This study aims to explore the role of 1-deoxynojirimycin (DNJ) in high glucose-induced β-cells and to further explore the molecular mechanism of DNJ effect on β-cells through network pharmacology. In the study, high glucose treatment of mouse INS-1 cells inhibited cell proliferation and insulin secretion, decreased the expression of Bcl-2 protein and Ins1 and Ins2 genes, promoted apoptosis, and increased cleaved caspase-3 and cleaved caspase-9 expression levels as well as intracellular reactive oxygen species production. DNJ treatment significantly restored the dysfunction of INS-1 cells induced by high glucose, and DNJ showed no toxicity to normal INS-1 cells.
