The σNS protein of NDRV antagonizes TRIM59-mediated antiviral innate immune response of Cherry Valley duck.

In recent years, outbreak of the novel duck reovirus (NDRV) disease has occurred frequently in duck populations. Due to its rapid spreading, absence of effective control methods, and high treatment costs, the NDRV disease has caused huge losses to waterfowl breeding in China. As reported, four non-structural (NS) proteins are encoded by the NDRV genome, among which the σNS protein is an RNA-binding protein that can improve the stability of bound RNA by forming oligomers (Adams and Cory, 1998).

Safety, efficacy, and immunogenicity of a novel IgG degrading enzyme (KJ103): results from two randomised, blinded, phase 1 clinical trials.

The approved intravenous adeno-associated virus (AAV) therapies are limited by the widespread prevalence of pre-existing anti-AAV antibodies in the general population, which are known to restrict patients' ability to receive gene therapy and limit transfection efficacy in vivo. To address this challenge, we have developed a novel recombinant human immunoglobulin G degrading enzyme KJ103, characterized by low immunogenicity and clinical value for the elimination of anti-AAV antibodies in gene transfer. Herein, we conducted two randomized, blinded, placebo-controlled, single ascending dose Phase I studies in China and New Zealand, to evaluate the pharmacokinetics, pharmacodynamics, safety and immunogenicity of KJ103 in healthy volunteers.

Self-template manufacturing of on-skin electrodes with 3D multi-channel structure for standard 3-limb-lead ECG suit.

Wearable electrocardiogram (ECG) devices are the mainstream technology in the diagnosis of various cardiovascular diseases, in which soft, flexible, permeable electrodes are the key link in human-machine interface to capture bioelectrical signals. Herein, we propose a self-template strategy to fabricate silver-coated fiber/silicone (AgCF-S) electrodes. With a simple dissolving-curing-redissolving process, the polyvinyl acetate shell around the AgCF core is in-situ removed to form a three-dimensional (3D) multi-channel structure.

Biomimic Nanodrugs Overcome Tumor Immunosuppressive Microenvironment to Enhance Cuproptosis/Chemodynamic-Induced Cancer Immunotherapy.

Elesclomol (ES) as an efficient Cu ionophore can specifically transport Cu into mitochondria and disrupt intracellular Cu homeostasis. Extra intracellular Cu induces cuproptosis and chemodynamic therapy (CDT), which further cascades immunogenic cell death (ICD) and activates antitumor immune responses. However, the tumor immunosuppressive microenvironment (TIM) attenuates the efficiency of the immune response.

Eliminating the tigecycline resistance RND efflux pump gene cluster tmexCD-toprJ in bacteria using CRISPR/Cas9.

Objectives: Tigecycline, a last-resort antibiotic in the tetracycline class, has been effective in treating infections caused by multidrug-resistant bacteria. However, the emergence of the tigecycline resistance gene cluster tmexCD-toprJ, which encodes a resistance-nodulation-division efflux pump, has significantly limited its therapeutic effectiveness. This study aims to explore the potential of CRISPR/Cas9-based plasmids to target and cleave tmexCD-toprJ gene cluster from bacterial plasmids and chromosomal integrative conjugative elements (ICEs), respectively.

Cannabis use disorder increases risk of large-artery atherosclerotic stroke and migraine with aura through mendelian randomization study.

Observational studies have shown some association between cannabis use disorder (CUD) and neurological disorders, but their causal relationship is unclear. In this study, we tested the potential causal relationship between CUD and three common neurological disorders using two-sample Mendelian randomization (TSMR) and multivariate MR (MVMR) methods. Thirty-two genetic loci were extracted as exposure factors from the largest genome-wide association study (GWAS) summary statistics for CUD to date.

The Gly103Arg variant in hereditary transthyretin amyloidosis.

Background: Hereditary transthyretin amyloidosis (ATTRv) is an autosomal dominant inherited systematic disease primarily affecting the peripheral and autonomic nervous system, heart, eyes and kidney. Over 140 variants have been identified worldwide, with the Gly103Arg variant reported exclusively in China. This variant is characterized by early onset eye manifestations, making accurate and timely diagnosis difficult.

The function of OforOrco in the allogrooming behavior of Odontotermes formosanus (Shiraki) induced by Serratia marcescens Bizio (SM1).

Termites are consistently confronted with a complex microbial environment. In addition to the role of their innate immune system in resisting pathogen infection, social immune behavior also plays a significant role in helping termites withstand the stress caused by pathogenic microorganisms. The allogrooming behavior among different individuals is commonly observed in termites, and it plays a crucial role in the social immune interaction network.

Effect of microwave treatment and water-bath heating treatment on the performance of glutenin from Tiger nut seed meal: Insights into changes in structural characteristics, functional properties, and in vitro gastrointestinal digestibility.

In this study, the structural characteristics, functional properties, and in vitro gastrointestinal digestibility of glutenin from Tiger nut seed meal (TNSMG) treated by microwave (140-700 W, 20-60 s) and water-bath heating (40-100 °C, 10-30 min) were investigated. Analysis of the surface hydrophobicity, intrinsic fluorescence spectroscopy and Fourier transform infrared spectroscopy indicated that both microwave and water-bath heating treatments caused structure changes of TNSMG. The results showed an increase in the exposure of sulfhydryl groups and the content of β-sheet, coupled with a decrease in the content of α-helix and β-turn.

To explore the underlying mechanism of this system, the current study is the first to use network analysis showing the dimension-level correlation patterns of daily stressors, subjective well-being (SWB), psychological distress and PsyCap during the pandemic.

Method: We recruited 1556 participants in China and assessed daily stressors, SWB, psychological distress, and PsyCap through self-report questionnaires.

G-Protein Coupled Receptor 1 Is Involved in Tetrachlorobisphenol A-Induced Inflammatory Response in Jurkat Cells.

Estrogens can affect the immune inflammatory response through estrogen receptor alpha (ERα), but the specific role of estrogen member receptor G-protein coupled receptor 1 (GPER1) in this process remains unclear. In this study, we evaluated the effects of tetrachlorobisphenol A (TCBPA), which has estrogen activity, on immune inflammatory-related indicators of Jurkat cells, as well as investigated the role of GPER1 in these effects. The results showed that TCBPA at lower concentrations significantly promoted the viability of Jurkat cells, whereas higher concentrations decreased cell viability.

Autism spectrum disorder (ASD) is neurodevelopmental disorder with a high incidence rate, characterized by social deficits and repetitive behaviors. There is currently no effective management available to treat the core symptoms of ASD; however, oxidative stress has been implicated in its pathogenesis. Edaravone (EDA), a free-radical scavenger, is used to treat amyotrophic lateral sclerosis (ALS) and acute ischemic stroke (AIS).

Degradation of perineuronal nets in the medial prefrontal cortex promotes extinction and reduces reinstatement of methamphetamine-induced conditioned place preference in female mice.

The high rate of relapse to compulsive methamphetamine (MA)-taking and seeking behaviors after abstinence constitutes a major obstacle to the treatment of MA addiction. Perineuronal nets (PNNs), essential components of the extracellular matrix, play a critical role in synaptic function, learning, and memory. Abnormalities in PNNs have been closely linked to a series of neurological diseases, such as addiction.
