Assessment of biocompatibility for citric acid crosslinked starch elastomeric films in cell culture applications.

This study investigates the synthesis of potato starch elastomers reinforced with silicon dioxide (SiO) and citric acid as a crosslinking agent to enhance their mechanical and barrier properties. Surface morphology analysis using optical microscopy revealed that pure potato starch films had uneven surfaces. However, higher SiO concentrations increased roughness, while citric acid crosslinked films displayed smoother surfaces overall.

Characteristics of microbial drug resistance and its correlates in chronic diabetic foot ulcer infections.

While virulence factors and the biofilm-forming capabilities of microbes are the key regulators of the wound healing process, the host immune response may also contribute in the events following wound closure or exacerbation of non-closure. We examined samples from diabetic and non-diabetic foot ulcers/wounds for microbial association and tested the microbes for their antibiotic susceptibility and ability to produce biofilms. A total of 1074 bacterial strains were obtained with staphylococci, Pseudomonas, Citrobacter and enterococci as major colonizers in diabetic samples.
