Metal-organic frameworks (MOFs) have been gaining significant attention due to their potential application in medicine. Here, we investigated the effect of zeolite imidazole framework-8 (ZIF-8) on neuro-behavioral parameters, histopathology, inflammation, and oxidative stress levels of rats' brain samples. Forty-eight male Wistar rats were injected by four injections of saline or ZIF-8 at different doses of 5, 10, or 20 mg/kg via the caudal vein.

Carbon quantum dots (CDs) are deemed particularly promising among various optical dyes, for enhancing polymeric networks with superior physical and chemical properties. This study presents the synthesis of CDs derived from Prunella vulgaris, a natural plant resource, through a single-step hydrothermal process, followed by their uniform integration into hydrogel matrices via an in situ free radical graft polymerization.

The predominant adverse health effects in care delivery result from hospital-acquired (nosocomial) infections, which impose a substantial financial burden on global healthcare systems. Integrating contact-killing antibacterial action, gas permeability, and antioxidant properties into textile coatings offers a transformative solution, significantly enhancing both medical and everyday protective applications. This study presents an innovative, pollution-free physical compounding method for creating a fluorescent biopolymer composite embedded with silicene-based heteroatom-doped carbon quantum dots for the production of functional textiles.

- - Cephalopods' unique abilities for visual communication and camouflage inspire the development of a new fluorescent biomaterial that can change colors when stretched or stimulated.
- - This innovative material is the first 3D-printed soft biomaterial made from carbon dots derived from chitosan and benzalkonium chloride, showcasing properties like high stretching ability, quick response to touch and pH changes, and resistance to UV light.
- - The research focuses on ensuring the hydrogel's durability through various stress tests and analyzes its performance using molecular dynamics modeling, aiming to address issues like short lifespan and complex manufacturing seen in existing soft materials.
Article Synopsis
- Polycystic ovary syndrome (PCOS) is a common hormonal disorder affecting women's reproductive health, characterized by various symptoms such as irregular or absent menstrual cycles, excess androgen levels, and ovarian dysfunction.
- The study involved 20 female Wistar rats divided into four groups, with one group receiving placenta-derived mesenchymal stem cells (PDMSCs) after inducing PCOS through a medication regimen; various health indicators were then assessed.
- Results showed that PDMSCs improved ovarian health by increasing healthy follicle counts, balancing hormone levels, reducing insulin resistance, and enhancing lipid profiles compared to the non-treated PCOS group.
