This study investigated the effects of lubricin on the gliding of repaired flexor digitorum profundus (FDP) tendons in vitro. Canine FDP tendons were completely lacerated, repaired with a modified Pennington technique, and treated with one of the following solutions: saline, carbodiimide derivatized gelatin/hyaluronic acid (cd-HA-gelatin), carbodiimide derivatized gelatin to which lubricin was ...

A new method was developed for the detection of single-base mutations in DNA. The polymerase chain reaction was used to prepare DNA fragments of up to 1 kb. Fragments that differed by a single-base were combined, denatured and renatured to generate heteroduplexes. The heteroduplexes were reacted with a water-soluble carbodiimide under conditions in which the carbodiimide modified Gs and Ts that...

BACKGROUND: Magnetic nanoparticles have been significantly used for coupling with biomolecules, due to their unique properties. METHODS: Magnetic nanoparticles were synthesized by thermal co-precipitation of ferric and ferrous chloride using two different base solutions. Glucose oxidase was bound to the particles by direct attachment via carbodiimide activation or by thiophene acetylation of ma...

The effect of Helminthosporium maydis race T toxin on electron transport in susceptible cytoplasmic male-sterile Texas corn (Zea mays L.) mitochondria was investigated, using dichlorophenol indophenol and ferricyanide as electron acceptors. Succinate-dependent electron transport was stimulated by the toxin, consistent with the well described increase in membrane permeability induced by the toxi...

One of the promising research area, which today is particular importance in biomedicine, use enzyme surface modified honeycomb carbon supports for biocatalysis and haemosorption. Patients suffering from hyperuricemia, with elevated blood levels urates are prone to diseases such as gout, chronic kidney disease, nephrolithiasis and, finally, an acute renal failure. In this work, monoliths were pr...
