The goal of this research is to develop innovative damage-responsive bacterial-based self-healing fibers (hereafter called BioFiber) that can be incorporated into concrete enable two functionalities simultaneously: (1) crack bridging functionality control growth and (2) healing when a occurs. BioFiber comprised load-bearing core fiber, sheath bacteria-laden hydrogel, an outer impermeable strain...

Considered one of the most important enzymes for the biotechnology industries, lipase is a very versatile biocatalyst been target of several researches and review papers and used in many different industrial applications, such as household detergent additive, chemicals and pharmaceutical compounds synthesis, biodiesel production and others. Lipase produced by Burkholderia cepacia was entrapped ...

OBJECTIVE Frusemide loaded calcium alginate micropellets, an oral microparticulate delivery system, was statistically optimized exhibiting prolonged therapeutic action minimizing its adverse effects. METHODS Ionotropic Gelation technique was adopted employing 3(2) Factorial designs and keeping the entire process free from organic solvents. Physicochemical and the release characteristics of th...

Delivery systems based on filled hydrogel particles (microgels) can be fabricated from natural food-grade lipids and biopolymers. The potential for controlling release characteristics by modulating the electrostatic interactions between emulsifier-coated lipid droplets and the biopolymer matrix within hydrogel particles was investigated. A multistage procedure was used to fabricate calcium algi...

An attempt was made to prepare FITC-labeled-lactoferrin (LF-FTC)-loaded microparticles, durable under gastrointestinal conditions, first by the combination of alginate/calcium complexation and emulsification-evaporation and next by treatment with chitosan solution. The obtained microparticles were examined for particle characteristics, in vitro release profiles and physical stability in solutio...

PURPOSE To examine the CT and MR appearances of four packing materials commonly used in otolaryngologic surgery. METHODS The CT and MR appearances of bismuth and iodoform paraffin paste, aqueous betadine gauze, calcium sodium alginate, and triadocortyl cream were examined. CT attenuation values were measured using phantoms containing packing materials. MR characteristics were examined by pack...

Introduction Single-walled carbon nanotubes (SWCNTs) are well known for their excellent mechanical and conductivity properties. These properties make SWCNTs ideal candidates as reinforcement elements in polymer composites [1]. In composite manufacturing, the main problem is the SWCNTs agglomeration in polymer matrix. This phenomenon limits the SWCNTs loading in composite fibers to 2-5 wt % of S...

BACKGROUND We evaluated the effect of calcium alginate as a hemostatic agent in a splenic injury model. METHODS Experimental rats (Wistar albino) were divided into four groups. Group I: Laparotomy was not performed. Group II: After laparotomy, the abdomen was closed without any splenic injury. Group III: After laparotomy, splenic injury about 0.5 cm in depth and 0.3 cm in length was created b...

Extracellular laccase was produced by Trametes versicolor IBL-04 using corn cobs as a substrate under pre-optimized culture conditions. A 64kDa laccase enzyme was purified and immobilized on calcium alginate beads using glutaraldehyde as a cross-linking reagent. Maximum enzyme immobilization efficiency (89%) was observed with 2-mm calcium-alginate beads that were developed using 4% (w/v) sodium...
