Study on the mechanism of lactic acid bacteria and their fermentation broth in alleviating hyperuricemia based on metabolomics and gut microbiota.

Introduction: Hyperuricemia (HUA) is a metabolic disease caused by purine metabolism disorders in the body. Lactic acid bacteria (LAB) and their fermentation broth have the potential to alleviate hyperuricemia, but the potential mechanism of action is still unclear.

Methods: The LAB with high inhibitory activity against xanthine oxidase (XOD) were screened out.

Myeloid-Derived Suppressor Cells Induce Exhaustion-Like CD8 T Cells during JEV Infection.

Japanese encephalitis (JE), caused by Japanese encephalitis virus (JEV), is a mosquito-borne zoonotic disease and a leading cause of viral encephalitis worldwide. While JEV has the ability to traverse the blood-brain barrier (BBB), the precise mechanisms by which it inhibits the immune response prior to penetrating the BBB remain unclear, presenting obstacles in the development of efficacious therapeutic interventions. This study investigated the impact of JEV on CD8 T cell responses, with a particular focus on the dysfunction of CD8 T cells during JEV infection.

Expression, optimization and biological activity analysis of recombinant type III collagen in Komagataella phaffii.

Type III collagen, a fundamental constituent of the extracellular matrix (ECM), is extensively utilized across the biomedicine, tissue engineering, and cosmetic industries because of its exceptional biocompatibility and biodegradability. Despite its widespread application, traditional methods of collagen production are often hindered by the limit yield, potential immunogenicity, and batch-to-batch variability. In the present study, we describe a synthetic biological approach for expressing full-length recombinant type III collagen (RCIII) in the Komagataella phaffii system.

Bioinspired adaptive lipid-integrated bilayer coating for enhancing dynamic water retention in hydrogel-based flexible sensors.

While hydrogel-based flexible sensors find extensive applications in fields such as medicine and robotics, their performance can be hindered by the rapid evaporation of water, leading to diminished sensitivity and mechanical durability. Despite the exploration of some effective solutions, such as introducing organic solvents, electrolytes, and elastomer composites, these approaches still suffer from problems including diminished conductivity, interface misalignment, and insufficient protection under dynamic conditions. Inspired by cell membrane structures, we developed an adaptive lipid-integrated bilayer coating (ALIBC) to enhance water retention in hydrogel-based sensors.

Effect of co-fermentation of non-Saccharomyces yeasts with Saccharomyces cerevisiae on the quality and flavor of blueberry wine.

The pure fermentation with Saccharomyces cerevisiae leads to a limited type and content of volatile aroma compounds in blueberry wine. This study analyzed the effect of three non-Saccharomyces yeasts (Candida glabrata E4, Pichia anomala E1, and Wickerhamomyces anomalus E3) on the quality and flavor of blueberry wine by co-fermenting them with S. cerevisiae NCUF309.

Kirigami-Inspired Stretchable Piezoelectret Sensor for Analysis and Assessment of Parkinson's Tremor.

Human muscle activity contains rich information that can reflect human movement patterns and conditions of diseases or physical abnormalities. Flexible pressure sensors enable the assessment of muscle tremors in Parkinson's disease (PD) through Force Myography (FMG). Here, an easily fabricated, ultra-sensitive, and stretchable piezoelectret pressure sensor is presented.

Metabolic biomarkers of neonatal sepsis: identification using metabolomics combined with machine learning.

Background: Sepsis is a common disease associated with neonatal and infant mortality, and for diagnosis, blood culture is currently the gold standard method, but it has a low positivity rate and requires more than 2 days to develop. Meanwhile, unfortunately, the specific biomarkers for the early and timely diagnosis of sepsis in infants and for the determination of the severity of this disease are lacking in clinical practice.

Methods: Samples from 18 sepsis infants with comorbidities, 25 sepsis infants without comorbidities, and 25 infants with noninfectious diseases were evaluated using a serum metabolomics approach based on liquid chromatography‒mass spectrometry (LC‒MS) technology.

Common carp Peptidoglycan Gecognition Protein 2 (CcPGRP2) alleviates gut dysbiosis induced by Aeromonas hydrophila.

Objectives: Peptidoglycan recognition protein 2 (PGRP2) plays a role in regulating immune defense in fish. Our previous studies found that CcPGRP2 helped maintain the integrity of the intestinal mucosa of carp and could bind and agglutinate bacteria when infected with A. hydrophila.

Concurrent predictors of behavioral inflexibility in minimally verbal and verbal autistic children.

Behavioral inflexibility (BI) refers to the rigid and inflexible patterns of behaviors that are a core aspect of autism. Few studies have investigated BI in autism separately from other restricted and repetitive behaviors (RRBs). The present study used a relatively new measure, the behavioral inflexibility scale (BIS; Lecavalier, L.

Blood Biomarker Detection Using Integrated Microfluidics with Optical Label-Free Biosensor.

In this study, we developed an optofluidic chip consisting of a guided-mode resonance (GMR) sensor incorporated into a microfluidic chip to achieve simultaneous blood plasma separation and label-free albumin detection. A sedimentation chamber is integrated into the microfluidic chip to achieve plasma separation through differences in density. After a blood sample is loaded into the optofluidic chip in two stages with controlled flow rates, the blood cells are kept in the sedimentation chamber, enabling only the plasma to reach the GMR sensor for albumin detection.

siRNAs Targeting Non-Human Species-Specific lncRNAs Trigger Cell Death in Human Colorectal Cancer Cells.

Species-specific long non-coding RNAs (lncRNAs) possess numerous unknown functions. We have recently reported that short interfering RNAs (siRNAs) designed to target mouse-specific lncRNAs caused cell death exclusively in human cancer cells, sparing normal human cells and mouse cancer cells. However, it is uncertain whether other non-human species-specific lncRNAs could also be applied as sequential targets for designing anti-tumor therapeutic siRNAs.

-Dihydroxylation by Synthetic Iron(III)-Peroxo Intermediates and Rieske Dioxygenases: Experimental and Theoretical Approaches Reveal the Key O-O Bond Activation Step.

Dioxygen (O) activation by iron-containing enzymes and biomimetic compounds generates iron-oxygen intermediates, such as iron-superoxo, -peroxo, -hydroperoxo, and -oxo, that mediate oxidative reactions in biological and abiological systems. Among the iron-oxygen intermediates, iron(III)-peroxo species are less frequently implicated as active intermediates in oxidation reactions. In this study, we present the combined experimental and theoretical investigations on -dihydroxylation reactions mediated by synthetic mononuclear nonheme iron-peroxo intermediates, demonstrating the importance of supporting ligands and metal centers in activating the peroxo ligand toward the O-O bond homolysis for the -dihydroxylation reactions.

Sohlh2 Promotes the Progression of Hepatocellular Carcinoma via TGM2-Mediated Autophagy.

Liver cancer is the third leading cause of cancer-related deaths worldwide, with hepatocellular carcinoma (HCC) accounting for 85% of liver cancer-related deaths. Autophagy controls HCC cell growth, invasion, metastasis, drug resistance, and stemness. Spermatogenesis and oogenesis basic helix-loop-helix transcription factor 2 (Sohlh2) can bind to the E-boxes in the promoter regions of target genes, which are involved in multiple neoplasms.

Melatonin Regulates the Expression of VEGF and HOXA10 in Bovine Endometrial Epithelial Cells through the SIRT1/PI3K/AKT Pathway.

Melatonin plays a critical role in regulating embryo attachment in ruminants. While numerous studies have investigated its effects on early embryo development in vitro, the precise mechanisms by which melatonin influences the receptivity of endometrial epithelial cells in dairy cows remain unclear. The prerequisite for embryo implantation is the specific physiological condition of the endometrium that allows the embryo to implant, also known as endometrial receptivity.

Recombinant collagen for the repair of skin wounds and photo-aging damage.

The skin, being the body's primary defense mechanism, is susceptible to various injuries such as epidermal wounds, natural aging, and ultraviolet-induced damage. As a result, there is growing interest in researching skin repair methods. Traditional animal-derived collagen, widely available on the market, poses risks due to its immunogenicity and potential for viral contamination.

Malware Identification Method in Industrial Control Systems Based on Opcode2vec and CVAE-GAN.

Industrial Control Systems (ICSs) have faced a significant increase in malware threats since their integration with the Internet. However, existing machine learning-based malware identification methods are not specifically optimized for ICS environments, resulting in suboptimal identification performance. In this work, we propose an innovative method explicitly tailored for ICSs to enhance the performance of malware classifiers within these systems.

A brain-to-gut signal controls intestinal fat absorption.

Although fat is a crucial source of energy in diets, excessive intake leads to obesity. Fat absorption in the gut is prevailingly thought to occur organ-autonomously by diffusion. Whether the process is controlled by the brain-to-gut axis, however, remains largely unknown.

Two 2D spin-crossover coordination polymers constructed by [Pd(SCN)] building blocks.

Two new two-dimensional (2D) coordination polymers, [Fe(L){Pd(SCN)}] (L = 2-methoxypyrazine, 1; and L = ()-3-(phenyldiazenyl)pyridine, 2), were successfully constructed by using square-planar [Pd(SCN)] building blocks. Complex 1 exhibits complete and one-step spin-crossover (SCO) behavior, while 2 exhibits incomplete and two-step SCO behavior. Further structural insight into this synergy reveals that the flat/flexing [Fe{Pd(SCN)}] sheets in 1 and 2 are stabilized by interlayered/intralayered supramolecular interactions.
