Natural biopolymers from plant sources contain many impurities (e.g., fat, protein, fiber, natural pigment and endogenous enzymes), therefore, an efficient purification process is recommended to minimize these impurities and consequently improve the functional properties of the biopolymer. The main objective of the present study was to investigate the effect of different purification techniques...

Biopolymer electrolyte based on carboxymethyl cellulose has been prepared by doping with different concentration of oleic acid via solution casting technique. Fourier Transform Infrared spectroscopy was used to study the complexation between the salt and polymer. New peak was observed at 1710, 2850, 2920 cm. X-ray diffraction study reveals the amorphous nature of the biopolymer electrolyte. Imp...

Degradable quantum channels are among the only channels whose quantum and private classical capacities are known. As such, determining the structure of these channels is a pressing open question in quantum information theory. We give a comprehensive review of what is currently known about the structure of degradable quantum channels, including a number of new results as well as alternate proofs...

We have developed synthetic hydrogel extracellular matrix (ECM) analogues that can be used to study mechanisms involved in cell migration, such as receptor-ligand interactions and proteolysis. The biomimetic hydrogels consist of bioinert polyethylene glycol diacrylate derivatives with proteolytically degradable peptide sequences included in the backbone of the polymer and adhesive peptide seque...

Fish scale biopolymer blended with nanocellulose crystals is used for production of microneedles applying mechanical press microfabrication and the effect of nanocellulose on microfabrication, water absorption, moisture stability and mechanical properties of the microneedles is reported. The results show that microneedles produced from the nanocellulose loaded fish scale biopolymer requires hig...

INTRODUCTION Alterations in the vocal folds that involve volume reduction and glottal closure failure result in exaggerated air escape during speech. For such situations, the use of implants or grafts of different materials has been proposed. OBJECTIVE To define the effect of sugarcane biopolymer gel when implanted in the vocal folds of rabbits. METHODS This was an experimental study. The v...

The aim of the research work was to isolate biopolymer and to evaluate its emulsifying ability by formulating o/w type of emulsion. The biopolymer was isolated from the fruit pulp of Prunus insititia by treating with water. The aqueous extract was treated with an optimized ratio of dimethyl ketone and kept in refrigeration for 6 hours. The biopolymer was collected by centrifugation, dried and s...

PURPOSE To evaluate the benefit of using carriers such as the biopolymer gel (hidrogel of polysaccharide of sugarcane molasses) associated with the bone morphogenetic proteins (BMP's) in the repair of critical bone defects in calvaria of Wistar rats. METHODS Forty-two rats were submitted to a surgical calvaria bone defects. These animals were divided into two experimental groups, positive con...

Ralstonia sp. strain MD27, a novel biopolymer-degrading betaproteobacterium, was isolated from compost samples. This organism has been shown to utilize the biopolymer poly(3-hydroxybutyrate) [P(3HB)] as a carbon source for growth. We report the draft genome sequence of MD27 with an estimated total sequence length of 5.9 Mb.
