Multifunctional and endogenous stimuli-responsive vinblastine sulfate/manganese dioxide nanodrugs for enhancing chemotherapeutic efficacy against hypoxic tumors.

Several solid tumors contain large hypoxic regions, diminishing drug responses and resulting in limited therapeutic outcomes. Vinblastine sulfate (VBL) targets the tubulin molecule, causing microtubule depolymerization and inducing mitotic arrest, leading to tumor regression. However, hypoxia causes microtubule depolymerization in tumor cells, reducing the number of intact microtubules for drug binding and diminishing the efficacy of microtubule-targeting agents like VBL.

Structural characterization and therapeutic potential of exopolysaccharide EPS-W-1 from Lactiplantibacillus plantarum strain ZL1 isolated from kimchi against DSS-induced colitis.

Ulcerative colitis (UC) is associated with intestinal barrier dysfunction, gut microbiome (GM) dysbiosis, inflammation, and immune dysregulation. Lactic acid bacteria-derived exopolysaccharides (LAB-EPS) have biotherapeutic potential to stimulate immune responses and influence the GM. Therefore, this work aimed to extract the bioactive EPS (EPS-W-1) from Lactiplantibacillus plantarum ZL1, isolated from Korean kimchi, and then characterize the chemical structure of EPS-W-1 using HPLC, GC-MS, and NMR.

Dynamic birefringence and chirality of magnetically controllable assemblies of anisotropic plasmonic nanoparticles in dispersion.

The ability to control the orientation and arrangement of plasmonic nanoparticles with shape anisotropy offers a promising route to achieving highly tunable optical properties. In this study, we introduce a synthetic approach for magnetically controllable plasmonic nanoparticles (MPs) consisting of an anisotropic gold core encapsulated by an iron oxide shell. The superparamagnetic property of the iron oxide shell enables rapid, reversible, and remotely controlled alignment of MPs, allowing for dynamic manipulation of their optical properties.

The Infratrochlear Nerve Block Reduces the Incidence of Postoperative Nausea Vomiting in Pediatric Patients Undergoing Strabismus Surgery-A Retrospective Study.

: Strabismus surgery in pediatric patients is associated with a high incidence of postoperative nausea and vomiting (PONV). Patients showing pain are more prone to develop PONV. As the infratrochlear nerve (ITN) block can ameliorate perioperative pain following strabismus surgery, we hypothesized that ITN block may influence PONV in pediatric patients undergoing strabismus surgery.

Metabolomics and network pharmacology approach to identify potential bioactive compounds from Trichoderma sp. against oral squamous cell carcinoma.

ANO1-downregulation induced by schisandrathera D: a novel therapeutic target for the treatment of prostate and oral cancers.

Anoctamin 1 (ANO1), a drug target for various cancers, including prostate and oral cancers, is an intracellular calcium-activated chloride ion channel that plays various physiopathological roles, especially in the induction of cancer growth and metastasis. In this study, we tested a novel compound isolated from , known as schisandrathera D, for its inhibitory effect on ANO1. Schisandrathera D dose-dependently suppressed the ANO1 activation-mediated decrease in fluorescence of yellow fluorescent protein; however, it did not affect the adenosine triphosphate-induced increase in the intracellular calcium concentration or forskolin-induced cystic fibrosis transmembrane conductance regulator activity.
