Evaluation of a chitosan-polyethylene glycol paste as a local antibiotic delivery device

作者： Luna Mingyi Zhang cheyenne Dahlmann The Center for Advanced Studies in Science Math and Technology of Joseph Wheeler High School 375 Holt Road MariettaGeorgia 30068USA

The Human-Inspired Algorithm（HIA） is a new algorithm that uses a given population（a group of candidate solutions） to improve the search for optimal solutions to continuous functions in different optimization applications such as non-linear *** imitates the intelligent search strategies of mountain climbers who use modern techniques（such as binoculars and cell phones） to effectively find the highest mountain in a given *** from Genetic Algorithms（GAs） and Bees Algorithms（BAs）,HIA divides a whole search space into multiple equal subspaces,evenly assigns the population in the subspaces,finds an elite subspace with the largest sum of function values,and uses more climbers（candidate solutions） to explore the elite subspace and fewer ones to explore the rest of the whole search *** use random search in local neighborhood search,whereas HIA uses GAs in local neighborhood search to obtain better *** locates a point with the largest function value among the elite sites and creates a hypercube with the point as its *** assigned climbers in the hypercube and the elite subspace continue to search for the optimal solution *** each loop,the hypercube and the elite subspace become smaller to have a larger chance to pinpoint the optimal *** results for three continuous functions with constraints and three continuous functions with box constraints can indicate that HIA is more efficient than GAs and ***,conclusions and future works are given.

AIM To investigate the efficacy of a chitosan/polyethylene glycol blended paste as a local antibiotic delivery device, particularly in musculoskeletal *** Acidic(A) chitosan sponges and neutralized(N) chitosan/polyethylene glycol(PEG) blended sponges were combined in ratios of 3A:2N, 1A:1N, and 2A:3N; then hydrated with phosphate buffered saline to form a chitosan/PEG paste(CPP). Both in vitro and in vivo studies were conducted to determine the potential CPP has as a local antibiotic delivery device. In vitro biocompatibility was assessed by the cytotoxic response of fibroblast cells exposed to the experimental groups. Degradation rate was measured as the change in dry mass due to lysozyme based degradation over a 10-d period. The antibiotic elution profiles and eluate activity of CPP were evaluated over a 72-h period. To assess the in vivo antimicrobial efficacy of the CPP, antibiotic-loaded paste samples were exposed to subcutaneously implanted murine catheters inoculated with Staphylococcus aureus. Material properties of the experimental paste groups were evaluated by testing the ejection force from a syringe, as well as the adhesion to representative musculoskeletal tissue *** The highly acidic CPP group, 3A:2N, displayed significantly lower cell viability than the control sponge group. The equally distributed group, 1A:1N, and the highly neutral group, 2A:3N, displayed similar cell viability to the control sponge group and are deemed biocompatible. The degradation studies revealed CPP is more readily degradable than the chitosan sponge control group. The antibiotic activity studies indicated the CPP groups released antibiotics at a constant rate and remained above the minimum inhibitory concentrations of the respective test bacteria for a longer time period than the control chitosan sponges, as well as displaying a minimized burst release. The in vivo functional model resulted in complete bacterial infection prevention in all catheters tr

Journal of Environmental Protection 2013年第11期4卷 1272-1279页

McLain Centro de Investigacion Cientifica de Yucatan Unidad de Ciencias del Agua Cancun Quintana Roo Mexico Northern Illinois University Department of Geology and Environmental Geosciences DeKalb USA University of Arizona Water Resources Re- search Center Tucson USA

The Yucatan Peninsula’s groundwater is experiencing increases in degradation due to swelling population and tourism;yet little is known about sources and transport of contaminants in drinking water supplies. The karst allows for rapid transport of microbial and chemical contaminants to the subsurface, resulting in significantly increased potential for pollution of groundwater. The objective of this research is to determine the occurrence, source, and extent of fecal contamination in the Tulum region of the Peninsula. A multi-analytical approach was undertaken in impacted and unimpacted groundwater locations;measurements included physicochemical parameters, total coliform and E. coli, Bacteroides (human vs total) and caffeine. The results indicate a variation in geochemistry from impacted to protected sites. The total coliform and E. coli show fecal contamination is wide spread. However, the presence of human Bacteriodes and caffeine in the water in the Tulum well field indicates that the recent human activities next to the well field are impacting the drinking water supply. This project is an assessment of the area’s current water quality conditions and the probable impact that the aforementioned growth would have on the area’s water supply. By applying multiple source parameter measurements, including molecular microbiology and chemical indicators it was confirmed the extent of fecal contamination of human origin covered the entire sampling region.
