Ru-Ph Nanozyme-Based Hydrogels for Tumor Chemodynamic Therapy by Enhancing Enzyme Catalytic Efficiency Through Multiple Pathways.

The discovery of nanozymes has opened new possibilities for tumor therapy. However, their reliance on the tumor microenvironment and limited catalytic efficiency hinder broader applications. In this study, ruthenium-phenanthroline nanoparticles (Ru-Phs) are synthesized by combining ruthenium with phenanthroline and subsequently coloaded with the proton pump inhibitor (PPI) pantoprazole into sodium alginate (ALG) to form a Ru-Phs-PPI-ALG hydrogel for in situ tumor therapy.

Hydrogen sulfide-mediated inhibition of ROCK exerts a vasoprotective effecton ischemic brain injury.

As a gas molecule, hydrogen sulfide (HS) exerts neuroprotective effects. Despite its recognized importance, there remains a need for a deeper understanding of HS's impact on vascular smooth muscle cells and its role in ischemic brain injury. This study employs encompassing cultured primary cerebral vascular smooth muscle cells, oxygen-glucose deprivation/reoxygenation model, in vitro vascular tone assessments, in vivo middle cerebral artery occlusion and reperfusion experimentation in male rats, and the utilization of ROCK knockout, to unravel the intricate relationship between H2S and cerebrovascular diastolic function.

CRISPR technology combined with isothermal amplification methods for the diagnosis of Candida albicans infection.

Since Candida albicans, a type of fungus, causes severe infections that pose a significant threat to human health, its rapid detection is critical in clinical antifungal therapy. Traditional fungal diagnostic approaches are largely based on the culture method. This method is time-consuming and laborious, taking about 48-72 h, and cannot identify emerging species, making it unsuitable for critically ill patients with bloodstream infections, sepsis, and so on.

NPC1 promotes the progression of hepatocellular carcinoma by mediating the accumulation of neutrophils into the tumor microenvironment.

Hepatocellular carcinoma remains a significant threat to human health. Recent studies have found that the intake of cellular cholesterol contributes to the development and progression of hepatocellular carcinoma, although the exact mechanisms remain unclear. Our analysis of transcriptomic and proteomic databases has identified increased mRNA and protein expression levels of NPC1, a cholesterol intracellular transporter protein, in hepatocellular carcinoma tissues.

Genetic susceptibility of diffuse large B-cell lymphoma: a meta genome-wide association study in Asian population.

Diffuse large B-cell lymphoma (DLBCL) is an aggressive malignancy and the most common form of non-Hodgkin lymphoma (NHL) that occurs worldwide. To discover risk factors and pathogenesis of DLBCL, we performed the largest GWAS of DLBCL to date in samples of East Asian ancestry, consisting of 2,888 patients with DLBCL and 12,458 controls. The meta-analysis identified three novel loci, rs2233434 on 6p21.

The relationships of metals exposure and disturbance of the vaginal microbiota with the risk of PROM: Results from a birth cohort study.

The vaginal microbiota is proposed to be associated with reproductive health. Exposure to metals during pregnancy is a risk factor for premature rupture of membranes (PROM). PROM can lead to serious maternal complications, thus, identifying the cause and therapeutic targets for it is crucial.

Exosomes of different cellular origins: prospects and challenges in the treatment of acute lung injury after burns.

Acute lung injury (ALI) is a critical clinical disease caused by direct factors (inhalation injury, gastroesophageal reflux, ) or indirect factors (including infection, sepsis, burn, shock, trauma, acute pancreatitis, fat embolism, drug overdose, ). ALI is characterized mainly by diffuse interstitial and alveolar edema caused by an uncontrolled inflammatory response and damage to the alveoli-capillary barrier and has very high morbidity and mortality rates. Currently, there is no effective treatment strategy other than mechanical ventilation, fluid management or other supportive treatments.
