OBJECTIVE Growth factors demonstrate mixed results improving wound healing. Amnion-derived multipotent cells release physiologic levels of growth factors and tissue inhibitors of metalloproteinases. This solution was tested in models of acute and chronic wound healing. METHODS Acute model: Sprague-Dawley rats underwent laparotomy incisions. The midline fascia was primed with phosphate-buffere...

Simple D-hexoses such as D-glucose, D-mannose, and D-galactose were found to form supramolecular complexes with folic acid (FA) in phosphate-buffered saline solution (PBS, pH 7.4) the gas phase. Pterin subunit of FA was be essential for molecular assembly hexoses, whereas PABA (p-amino benzoic acid) GLN (glutamic subunits have virtually no effect on formation. Experimental measurements along DF...

A linear increase in cell uptake of nitrogen mustard, methyl-bis(beta-chloroethyl)amine (HN2), between 1 and 5 min, was observed after in vitro incubation of Ehrlich ascites tumor cells at 37 degrees C in phosphate-buffered saline containing HN2 followed by washing in 0 degrees C phosphate-buffered saline. After a second incubation in 37 degrees C phosphate-buffered saline without HN2, the cell...

OBJECTIVE To evaluate the efficacy of subconjunctival nanoparticle carboplatin in the treatment of transgenic murine retinoblastoma. METHODS Dendrimeric nanoparticles loaded with carboplatin were prepared. Forty LHbeta-Tag mice were randomly assigned into 4 groups and treated at 10 weeks of age. Each mouse received a single subconjunctival injection in one eye, and the opposite eye was left u...

Antibody-functionalized magnetic nanoparticles dispersed in phosphate-buffered saline solution were used as reagents immunomagnetic reduction assays. Biomolecules are detected bioliquid samples when they associate with and reduce the AC susceptibility χ ac of reagent at a given frequency. In this study, chemical kinetics for real-time during association was investigated. The between biomolecule...

The present work reported the preparation of biocomposites based on poly(3-hydroxybutyrate) (PHB), plasticizer, and bacterial cellulose (BC) by melt processing their testing means thermal properties (DSC), water absorption, in vitro degradation. surface was analyzed via atomic force microscopy (AFM). In degradation evaluated weight loss (DSC) assessment after immersion specimens phosphate-buffe...

Abstract Plasma‐treated water solutions (PTWS) allow the delivery of reactive oxygen and nitrogen species (RONS) to cells tissues for different purposes. The mechanism RONS formation has been clearly modelled in simple liquids like water, by assuming a plasma‐driven process independent from liquid. PTWS biological experiments, however, are often produced complex composition, where is far being ...
