Gut microbiota regulate insomnia-like behaviors via gut-brain metabolic axis.

Sleep interacts reciprocally with the gut microbiota. However, mechanisms of the gut microbe-brain metabolic axis that are responsible for sleep behavior have remained largely unknown. Here, we showed that the absence of the gut microbiota can alter sleep behavior.

CD36-mediated podocyte lipotoxicity promotes foot process effacement.

Background: Lipid metabolism disorders lead to lipotoxicity. The hyperlipidemia-induced early stage of renal injury mainly manifests as podocyte damage. CD36 mediates fatty acid uptake and the subsequent accumulation of toxic lipid metabolites, resulting in podocyte lipotoxicity.

Nicotinamide mononucleotide alleviates endotoxin-induced acute lung injury by modulating macrophage polarization via the SIRT1/NF-κB pathway.

Context: Sepsis-induced acute lung injury (ALI) is a severe condition with limited effective therapeutics; nicotinamide mononucleotide (NMN) has been reported to exert anti-inflammatory activities.

Objective: This study explores the potential mechanisms by which NMN ameliorates sepsis-induced ALI and .

Materials And Methods: Cultured MH-S cells and a murine model were used to evaluate the effect of NMN on sepsis-induced ALI.

Enteric fungi protect against intestinal ischemia-reperfusion injury via inhibiting the SAA1-GSDMD pathway.

Introduction: Prophylactic antifungal therapy has been widely used for critical patients, but it has failed to improve patient prognosis and has become a hot topic. This may be related to disruption of fungal homeostasis, but the mechanism of fungi action is not clear. As a common pathway in critical patients, intestinal ischemia-reperfusion (IIR) injury is fatal and regulated by gut microbiota.

Efficient and simultaneous removal of aflatoxin B, B, G, G, and zearalenone from vegetable oil by use of a metal-organic framework absorbent.

Vegetable oils are usually cocontaminated with different mycotoxins, including aflatoxins and zearalenone, which cause significant food safety issues. Establishment of multitarget, high-efficiency, and low-cost adsorption methods are considered to be ideal solutions for mycotoxin removal in vegetable oils. In this study, we used metal-organic frameworks (MOFs) were used for the simultaneous removal of aflatoxins and zearalenone from vegetable oils.

Tannins amount determines whether tannase-containing bacteria are probiotic or pathogenic in IBD.

The role of dietary tannin in inflammatory bowel disease (IBD) is still not clear. Therefore, we aim to study the effect of TA in the progression of IBD. Dextran sulphate sodium (DSS)-induced model was used to mimic IBD.

Protective Effect of Electroacupuncture on the Barrier Function of Intestinal Injury in Endotoxemia through HO-1/PINK1 Pathway-Mediated Mitochondrial Dynamics Regulation.

Background And Aims: Endotoxemia (ET) is a common critical illness in patients receiving intensive care and is associated with high mortality and prolonged hospital stay. The intestinal epithelial cell dysfunction is regarded as the "engine" of deteriorated ET. Although electroacupuncture (EA) can mitigate endotoxin-induced intestinal epithelial cell dysfunction in ET, the mechanism through which EA improves endotoxin-induced intestinal injury for preventing ET deterioration needs further investigation.

Capsaicin regulates dyslipidemia by altering the composition of bile acids in germ-free mice.

The improvement of lipid metabolism by capsaicin (CAP) has been extensively studied, mostly with respect to the vanilloid type 1 (TRPV1) ion channel and intestinal flora. In this study, a model was established in germ-free mice by using resiniferatoxin (RTX) to ablate TRPV1 ion channels. Bile acid composition, blood parameters, and colonic transcriptome analyses revealed that CAP could improve dyslipidemia caused by high-fat diet even in the absence of TRPV1 ion channels and intestinal flora.

[Metal-organic framework UiO-67-based enrichment and purification of progesterone residues in milk].

Progesterone functions as an endocrine-disrupting compound. Imitating endogenous hormones disrupt the animals' hormone levels. The potential hazard of progesterone in milk cannot be neglected.

Knockdown of miR-92a suppresses the stemness of colorectal cancer cells via mediating SOCS3.

Antifungal Treatment Aggravates Sepsis through the Elimination of Intestinal Fungi.

Prophylactic antifungal therapy is widely adopted clinically for critical patients and effective in reducing the morbidity of invasive fungal infection and improves outcomes of those diagnosed patients; however, it is not associated with higher overall survival. As intestinal commensal fungi play a fundamental role in the host immune response in health and disease, we propose that antifungal therapy may eliminate intestinal fungi and aggravate another critical syndrome, sepsis. Here, with murine sepsis model, we found that antifungal therapy with fluconazole dismissed intestinal fungal burden and aggravated endotoxin-induced but no gram-positive bacteria-induced sepsis.

[Increased expression of LC3 in peripheral blood mononuclear cells is related to disease status in patients with rheumatoid arthritis].

Objective To detect the mRNA and protein expression of microtubule-associated protein 1 light chain 3 (LC3) in peripheral blood mononuclear cells (PBMCs) of patients with rheumatoid arthritis (RA), and to investigate its relationship with RA. Methods Twenty-two patients with RA and 16 healthy subjects with matching gender and age as controls were included in the study. PBMCs were isolated by density gradient centrifugation.

Therapeutic effect of polysaccharide of large yellow croaker swim bladder on lupus nephritis of mice.

The therapeutic effect of polysaccharide of large yellow croaker swim bladder (PLYCSB) on lupus nephritis has been studied in vivo. A high concentration (50 mg/kg dose) of PLYCSB reduced the levels of serum inflammatory cytokine levels of IL-6, IL-12, TNF-α and IFN-γ compared to a low concentration (25 mg/kg dose) and control mice. SCr, BUN, TC and TG serum levels of PLYCSB treated mice were lower than those of control mice, and TP and ALB serum levels were higher than control mice.
