Restorative Effects of Short-Chain Fatty Acids on Corneal Homeostasis Disrupted by Antibiotic-Induced Gut Dysbiosis.

The gut microbiota plays a crucial regulatory role in various physiological processes, yet its impact on corneal homeostasis remains insufficiently understood. Here, we investigate the effects of antibiotic-induced gut dysbiosis (AIGD) and germ-free (GF) conditions on circadian gene expression, barrier integrity, nerve density, and immune cell activity in the corneas of mice. Through RNA sequencing, we found that both AIGD and GF conditions significantly disrupted the overall transcriptomic profile and circadian transcriptomic oscillations in the cornea.

Hotspots of nitrogen losses from anthropogenic sources in the Huang-Huai-Hai Basin, China.

Poor management of nitrogen (N) can lead to serious environmental problems, such as air and water pollution. The accurate identification of priority control areas and emission sources is critical for making effective decisions regarding sustainable N management. This study aimed to identify hotspots for N losses and quantitatively analyze the relative contributions of different emission sources in the Huang-Huai-Hai Basin at the county scale.

LncRNA TMC3-AS1 silence alleviates lipopolysaccharide-induced acute kidney injury by suppressing Wnt5a-mediated autophagy and pyroptosis pathway.

Long non-coding RNA TMC3-AS1 is identified to be upregulated by lipopolysaccharide (LPS) in inflammatory disease, but its role in acute kidney injury (AKI) is almost unknown. The study investigated the involvement of TMC3-AS1 in LPS-induced AKI and its downstream molecular regulatory mechanism. Our data suggested that knocking down TMC3-AS1 significantly reduced renal dysfunction, tissue inflammation and tissue damage in LPS-induced mice, and promoted cell viability, inhibited inflammation, apoptosis and necrosis in LPS-stimulated human renal tubular epithelial cells HK2.

Direct engulfment of synapses by overactivated microglia due to cadmium exposure and the protective role of Nrf2.

Cadmium (Cd), a notorious environmental pollutant, has been linked to neurological disorders, but the underlying mechanism remains elusive. We aimed to explore the role of microglia in Cd-induced synaptic damages at environmentally relevant doses and whether microglia directly engulf synaptic structures. Nrf2 is deeply implicated in the status of microglial activation; therefore, we also investigated whether it is involved in the above process.

Synergistic effects of PS-NPs and Cd on ovarian toxicity in adolescent rats: Ferroptosis by induction of mitochondrial redox imbalance via the SIRT3-SOD2/Gpx4 pathway.

Nanoplastics (NPs) are an emerging class of pollutants. They can act as a"Trojan horse" to change the bioavailability and toxicity of heavy metals in the environment. However, research on the combined toxicity of heavy metals and NPs is scarce, especially during the critical developmental period of adolescence.

Gastrodin: Modulating the xCT/GPX4 and ACSL4/LPCAT3 pathways to inhibit ferroptosis after ischemic stroke.

Unlabelled: Ischemic stroke ranks as the second leading cause of global mortality and disability. Although reperfusion is crucial for salvaging brain tissue, it carries the risk of secondary injuries, such as ferroptosis. Gastrodin, a neuroprotective compound found in Chinese herbal medicine, may regulate this process.

Rapid evaluation of hepatocellular carcinoma by detecting plasma exosomes with time-resolved fluorescence immunochromatographic test strips.

Time-resolved fluorescence immunochromatographic test strips (TRFIS) was developed for the rapid detection of hepatocellular carcinoma (HCC)-specific plasma exosomes (hExos) by targeting the hExo-surface membrane protein glypican-3 (GPC3). The GPC3-TRFIS could directly detect plasma exosomes without the isolation and purification process, and the whole immunoassay could be completed within 15 min. The visual detection limit of GPC3-TRFIS was 3.

Dietary and lifestyle oxidative balance score was negatively associated with the risk of diabetic kidney disease: NHANES 2005-2020.

Aims: There is a potential association between oxidative stress and the development of diabetic kidney disease (DKD). The Oxidative Balance Score (OBS), derived from dietary and lifestyle factors, acts as a comprehensive marker of oxidative stress. Research examining the relationship between OBS and DKD is scarce.

A patent review of xanthine oxidase inhibitors (2021-present).

Introduction: Xanthine oxidase (XO) catalyzes the oxidation of both hypoxanthine and xanthine in the last two steps of the purine metabolic pathway, serving as a rate-limiting enzyme for uric acid production as well as a key target for the treatment of gout and other hyperuricemia-related conditions.

Areas Covered: This paper reviews XO inhibitors in patents from 2021 to the present. We summarize in detail the structural classes and characteristics, in vitro and in vivo biological results, and structure‒activity relationships of synthetic inhibitors, as well as the sources, specific structures, research methods, and biological activities of XO inhibitors from natural products.

SAM-dPCR: Accurate and Generalist Nuclei Acid Quantification Leveraging the Zero-Shot Segment Anything Model.

Digital PCR (dPCR) has transformed nucleic acid diagnostics by enabling the absolute quantification of rare mutations and target sequences. However, traditional dPCR detection methods, such as those involving flow cytometry and fluorescence imaging, may face challenges due to high costs, complexity, limited accuracy, and slow processing speeds. In this study, SAM-dPCR is introduced, a training-free open-source bioanalysis paradigm that offers swift and precise absolute quantification of biological samples.

The current imbalance in the allocation of dental human resources has created a significant disparity between the demand for and supply of dental auxiliaries.

Association between the triglyceride to high-density lipoprotein cholesterol ratio and type 2 diabetes mellitus in non-alcoholic fatty liver disease.

This study evaluated the ability of the triglyceride (TG) to high-density lipoprotein cholesterol (TG/HDL-C) ratio to identify individuals at risk of type 2 diabetes mellitus (T2DM) in the non-alcoholic fatty liver disease (NAFLD) population. We retrospectively studied 4,769 patients with NAFLD from the Affiliated Hospital of Hangzhou Normal University (2020-2023).
