Effects of silver nanoparticles-polysaccharide on bleomycin-induced pulmonary fibrosis in rats.

Objectives: The first goal of this study was to synthesize the silver nanoparticles Alcaligenes xylosoxidans exopolysaccharide (Ag-AXEPS). The second objective was to analyse the role of Ag-AXEPS nanoparticles (NPS) in treating bleomycin (BLM)-induced lung fibrosis.

Methods: Intratracheal bleomycin (2.

Influence of adding zeolite loaded with different charges to semen extender on sperm quality in rabbits after cryopreservation.

The aim of the present study was to investigate the effect of supplementing rabbit semen extender with zeolite loaded with different charges (Z or Z, Z) on sperm cryopreservation. Semen was collected from six healthy, fertile New Zealand rabbit bucks using an artificial vagina. The collected ejaculates were pooled and diluted with a tris-yolk fructose (TYF) extender supplemented with Z (+16, +12, +8, -16, -12, and -8) at a concentration of 1% for a final sperm concentration of 25 × 10 sperm cells/mL.

Effect of Tumor Suppressor MiR-34a Loaded on ZSM-5 Nanozeolite in Hepatocellular Carcinoma: In Vitro and In Vivo Approach.

Background: MicroRNA modulation therapy has shown great promise to treat hepatocellular carcinoma (HCC), however Efficient tissue-specific and safe delivery remains a major challenge.

Objective: We sought to develop an inorganic-organic hybrid vehicle for the systemic delivery of the tumor suppressor miR-34a, and to investigate the efficiency of the delivered miR-34a in the treatment of HCC in vitro and in vivo.

Methods: In the present study, pEGP-miR cloning and expression vector, expressing miR-34a, was electrostatically bound to polyethyleneimine (PEI), and then loaded onto ZSM-5 zeolite nanoparticles (ZNP).
