Gentamicin Release Study in Uniaxial and Coaxial Polyhydroxybutyrate-Polyethylene Glycol-Gentamicin Microfibers Treated with Atmospheric Plasma.

The skin is the largest organ and one of the most important in the human body, and is constantly exposed to pathogenic microorganisms that cause infections; then, pharmacological administration is required. One of the basic medical methods for treating chronic wounds is to use topical dressings with characteristics that promote wound healing. Fiber-based dressings mimic the local dermal extracellular matrix (ECM), maintaining an ideal wound-healing climate.

Degradation of Acid Red 1 Catalyzed by Peroxidase Activity of Iron Oxide Nanoparticles and Detected by SERS.

Magnetic iron oxide nanoparticles (MIONPs) were synthesized using tannic acid and characterized by Raman, FTIR, UV, and DRX spectroscopy. In a heterogeneous Fenton-like reaction, the catalytic peroxidase-like activity of MIONPs in the degradation of Acid Red 1 (AR 1) dye was investigated. TEM/STEM was used to determine the quasi-spherical morphology and particle size (3.

Regulation of antibiotic sales in Mexico: an analysis of printed media coverage and stakeholder participation.

Background: Restricting antibiotics sales to those with medical prescriptions only is a central strategy for promoting appropriate use and containing antibiotic resistance; however, many low and middle income countries have not enforced policies that prevent widespread self-medication with antibiotics. In 2010, the Mexican government announced the enforcement of antibiotic sales regulations, a policy that gained media prominence. This study analyzes media coverage of issues, stakeholder representation, and positions taken during policy agenda setting, drafting, and implementation to shed light on policy making to promote appropriate antibiotic utilization.
