Nanohybrid Hydrogel with Dual Functions: Controlled Low-Temperature Photothermal Antibacterial Activity and Promoted Regeneration for Treating MRSA-Infected Bone Defects.

Methicillin-resistant Staphylococcus aureus (MRSA)-related bone defects pose significant clinical challenges due to treatment failures. Here, an injectable nanohybrid hydrogel (FND-ZHD) is developed that combines controlled low-temperature photothermal antibacterial therapy with enhanced bone regeneration. The hydrogel uses Pluronic F-127 as the matrix, incorporating polydopamine-coated nano-hydroxyapatite and zinc oxide nanoparticles encapsulated with polydopamine and hyaluronic acid, forming a sophisticated nanostructured composite.

Anti-Osteoporosis and Bone Protective Effects of Resveratrol in Rats With Chronic Kidney Disease-Induced Osteoporosis.

Chronic kidney disease (CKD)-induced osteoporosis is a new concept that implies CKD-related impaired bone quality. Resveratrol (RES) is a natural component, known for its anti-inflammatory and anti-osteoporotic effects. In the present study, we aimed to investigate the bone-protective and anti-osteoporotic effects of resveratrol in rats with chronic kidney disease-induced osteoporosis.

YBX1 Modulates Intimal Hyperplasia by Regulating Expression and Alternative Splicing of Cell Cycle Associated Genes in RASMCs.

IDO1 inhibition enhances CLDN18.2-CAR-T cell therapy in gastrointestinal cancers by overcoming kynurenine-mediated metabolic suppression in the tumor microenvironment.

Background: Chimeric antigen receptor (CAR)-T cell therapy has achieved remarkable success in hematologic malignancies but faces significant limitations in gastrointestinal tumors due to the immunosuppressive tumor microenvironment (TME). Indoleamine 2,3-dioxygenase 1 (IDO1), a key enzyme in the TME, suppresses T cell efficacy by catalyzing tryptophan degradation to kynurenine (Kyn), leading to T cell exhaustion and reduced cytotoxicity. This study investigates the role of IDO1 inhibition in overcoming metabolic suppression by kynurenine and enhancing Claudin18.

Motor developmental delay in preschoolers with autism spectrum disorders in China and its association with core symptoms and maternal risk factors: a multi-center survey.

Prefabricated building construction in materialization phase as catalysts for hotel low-carbon transitions via hybrid computational visualization algorithms.

This study examines the carbon emissions of star-rated hotels in Hangzhou, comparing the environmental impact of prefabricated construction (PC) and conventional construction (CC) methodologies. The research reveals that PC generally results in lower carbon emissions during the materialization phase, with notable variations across different hotel star levels and administrative regions. Higher-star hotels exhibit higher total emissions, primarily due to larger scale and reliance on conventional construction methods.

GGCT Inhibits Ferroptosis in PTC Cells by Upregulating p53 Through RPS15A.

γ-Glutamine cyclotransferase (GGCT) is an enzyme involved in the metabolic cycle of glutathione (GSH). Abnormal GSH metabolism is mostly related to ferroptosis. However, the mechanisms supporting aberrant GGCT expression in PTC remain to be investigated.

Neuraminidase and nitric oxide dual response via PSA-PLGA nanoparticles: A novel approach for controlling Glaesserella parasuis inflammation and infection.

The overexpression of virulence factors and the induced inflammatory cytokine storm, resulting in tissue damage, represent significant challenges in treating antibiotic-resistant bacterial infections with conventional antibiotics. Herein, we have developed a bifunctional nanoparticle loaded with antibiotics (PSA@PLGA-TD/SMT) designed for precise response to the virulence proteins of drug-resistant bacteria while protecting the host from excessive inflammatory damage. This is achieved by modifying polylactic-co-glycolic acid (PLGA) nanoparticles with polysialic acid (PSA).

Lactate dehydrogenase B deficiency-dependent hyperlactatemia coordinates with necroptosis to worsen septic liver and kidney injuries.

Hyperlactatemia is intimately correlated with severity and poor prognosis of patients with sepsis. However, little experimental evidence on this process is known. We report here that lactate dehydrogenase B (LDHB), the glycolytic enzyme that catalyzes conversion of lactate to pyruvate, is transcriptionally downregulated in blood samples of hyperlactatemic patients, while mice receiving lactate injection have reduced LDHB activity in liver and kidney.

Background: Aristolochic acids (AAs)-containing herbs have been used as medicinal remedies for thousands of years. However, exposure to AAI and AAII increases the risk of nephropathy and cancers. Our previous study identified AAIVa, an analogue without carcinogenicity or nephrotoxicity, exerted anti-inflammatory effects.

Emission and risk of atmospheric hexachlorobutadiene might be underestimated globally.

Ambiguous emission of new pollutants is a fundamental obstacle of risk prevention, such as hexachlorobutadiene (HCBD).

Considering treatment efficiency, emissions of 362 kinds of sources were measured.

Nintedanib abrogates patient vitreous-induced Akt activation and tube formation of human retinal microvascular endothelial cells.

Growth factors and cytokines in the vitreous are critical drivers of proliferative diabetic retinopathy (PDR), a condition in which many patients exhibit resistance to current therapies. PDR is characterized by the formation of fibrovascular membranes on the vitreous side of the retina, which, if untreated, can lead to retinal detachment. Nintedanib, a clinically approved drug for idiopathic pulmonary fibrosis, targets multiple tyrosine kinases, including vascular endothelial growth factor receptors (VEGFRs), platelet-derived growth factor receptors (PDGFRs), and fibroblast growth factor receptors (FGFRs).

An antidepressant mechanism underlying the allosteric inhibition of GluN2D-incorporated NMDA receptors at GABAergic interneurons.

-methyl-d-aspartate receptors (NMDARs), key excitatory ion channels, have gained attention as anti-depression targets. NMDARs consist of two GluN1 and two GluN2 subunits (2A-2D), which determine their pharmacological properties. Few compounds selectively targeting GluN2 subunits with antidepressant effects have been identified.

Through a straightforward one-step pyrolysis approach, the obtained catalyst integrated nitrogen functionalities and bimetallic active sites, enabling it to achieve an outstanding catalytic performance.

One-Month-Old Rabbits Exhibit a Longer Postoperative Remodeling in Extraocular Muscles Compared to 3-Month-Old Rabbits.

Purpose: To explore whether there is a difference in postoperative extraocular muscle (EOM) remodeling between 1-month-old and 3-month-old rabbits.

Methods: Recession (n = 16) and resection (n = 16) were performed on the right superior rectus (SR) muscles of 1-month-old and 3-month-old rabbits. SR tissues were harvested 1 and 4 weeks post-surgery (n = 4 for each group), and mid-belly sections were used to assess myosin heavy chain (MyHC) isoform expression (fast 2X, embryonic, and neonatal MyHCs), activated satellite cells (SCs), and centrally nucleated myofibers.
