Biological evaluation of a new highly sensitive and selective fluorescent probe for hypochlorous acid and its imaging application in cell and zebrafish.

Hypochlorous acid is one of the most widely distributed reactive oxygen species in vivo. It is usually used as a signal molecule to participate in various life activities such as immunity and metabolism, and plays a notable role in maintaining homeostasis. When hypochlorous acid level is abnormal in the body, it will lead to a variety of diseases, such as Parkinson's disease, Alzheimer's disease, atherosclerosis and cancer.

Orally Administered Functional Polyphenol-Nanozyme-Armored Probiotics for Enhanced Amelioration of Intestinal Inflammation and Microbiota Dysbiosis.

Maintaining microbiota balance and enhancing the antioxidant performance of nanozyme-based probiotic systems are crucial for effective inflammatory bowel disease (IBD) therapy. Despite significant advancements, developing a green and safe coating technology that functionalizes probiotics with nanozymes while preserving the activity of both components remains a challenge. To address this, chitosan-modified epigallocatechin gallate (EGCG-CS, EC)is synthesized, leveraging the intrinsic adhesive and coordination properties of polyphenols to capture gold nanozymes (AuNPs), forming ECA complexes that enhance nanozyme activity.

Gene Variants Predispose Individuals to Tetralogy of Fallot.

Unlabelled: Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart malformation. While a few susceptibility genes for TOF have been identified, research on the genetic basis of TOF is limited. The () gene encodes the macrophage-stimulating protein receptor with tyrosine phosphatase activity that is involved in immune defense.

Trichomonas vaginalis adhesion protein 33 (TvAP33) promotes HPV infection by upregulating the expression of HPV membrane receptor molecules.

An increasing number of studies have identified Trichomonas vaginalis (T. vaginalis) as a risk factor for human papillomavirus (HPV) infection, yet experimental data and the mechanisms involved are still lacking. Wild-type and T.

siRNA-AGO2 complex inhibits bacterial gene translation: A promising therapeutic strategy for superbug infection.

Silencing resistance genes of pathogenic bacteria by RNA interference (RNAi) is a potential strategy to fight antibiotic-resistant bacterial infections. Currently, RNAi cannot be achieved in bacteria due to the lack of RNA-induced silencing complex machinery and the difficulty of small interfering RNA (siRNA) delivery. Here, we show that exosomal siRNAs can be efficiently delivered into bacterial cells and can silence target genes primarily through translational repression without mRNA degradation.
