To what extent does hyaluronic acid affect healing of xenografts? A histomorphometric study in a rabbit model

J. appl. oral sci; 26 (), 2018
ABSTRACT Among the many graft materials that have been used for the treatment of bone defects in oral and maxillofacial regions is xenograft. To improve osteoconductive effects of xenografts, they have been combined with various biocompatible materials, such as hyaluronic acid and bone morphogenetic prot...

Physicochemical comparison of commercial VS. extracted β-glucans and structural characterization after enzymatic purification

Vitae (Medellín); 25 (1), 2018
Background: β-glucans (1-3: 1-4) are soluble fibers applied to foods due to their technological properties (water binding capacity, viscosity, emulsification and stabilization) and their beneficial effects on health. The functional properties of β-glucans can be lost during the extraction and purificat...

Quality of bevacizumab (Avastin®) repacked in single-use glass vials for intravitreal administration

Arq. bras. oftalmol; 80 (2), 2017
ABSTRACT Purpose: Avastin® (bevacizumab) is an anti-vascular endothelial growth factor (VEGF) monoclonal antibody given as an off-label drug by intravitreal administration for treatment of ocular diseases. The drug's clinical application and its cost-benefit profile has generated demand for its divisio...

Characterization and bioactivities of a novel polysaccharide obtained from Gracilariopsis lemaneiformis

An. acad. bras. ciênc; 89 (1), 2017
ABSTRACT Gracilariopsis lemaneiformis is a type of red alga that contains seaweed polysaccharide agar. In this study, a novel non-agar seaweed polysaccharide fraction named GCP (short of crude polysaccharide obtained from Gracilariopsis lemaneiformis) was isolated from Gracilariopsis lemaneiformis. Struc...

Total protein composition of young and adult Biomphalaria alexandrina snails with different compatibilities to Schistosoma mansoni infection

Rev. biol. trop; 64 (4), 2016
Abstract:Schistosomiasis remains a disease of major global public health concern since it is a chronic and debilitating illness. The widely distributed Schistosoma mansoni that causes intestinal schistosomiasis represents a great threat. Its world-wide distribution is permitted by the broad geographic ra...

Therapeutic effect of low molecular weight chitosan containing sepia ink on ethanol-induced gastric ulcer in rats

Acta cir. bras; 31 (12), 2016
ABSTRACT PURPOSE: To evaluate the role of low molecular chitosan containing sepia ink (LMCS) in ethanol-induced (5 ml/kg) gastric ulcer in rats. METHODS: Animals were divided into four groups (n = 12): normal group (Normal), negative control group (Con), experiment group (LMCS) and positive control Om...

Process optimization for production and purification of a thermostable, organic solvent tolerant lipase from Acinetobacter sp. AU07

Braz. j. microbiol; 47 (3), 2016
ABSTRACT The purpose of this study was to isolate, purify and optimize the production conditions of an organic solvent tolerant and thermostable lipase from Acinetobacter sp. AU07 isolated from distillery waste. The lipase production was optimized by response surface methodology, and a maximum production...

Xylanase and beta-xylosidase from Penicillium janczewskii: Purification, characterization and hydrolysis of substrates

Electron. j. biotechnol; 19 (5), 2016
Background: Xylanases and β-D-xylosidases are the most important enzymes responsible for the degradation of xylan, the second main constituent of plant cell walls. Results: In this study, the main extracellular xylanase (XYL I) and p-xylosidase (BXYL I) from the fungus Penicillium janczewskii were p...

Purification and characterization of an aspartic protease from the Rhizopus oryzae protease extract, Peptidase R

Electron. j. biotechnol; 17 (2), 2014
Background Aspartic proteases are a subfamily of endopeptidases that are useful in a variety of applications, especially in the food processing industry. Here we describe a novel aspartic protease that was purified from Peptidase R, a commercial protease preparation derived from Rhizopus oryzae. Results ...

A new low molecular mass alkaline cyclodextrin glucanotransferase from Amphibacillus sp. NRC-WN isolated from an Egyptian soda lake

Electron. j. biotechnol; 16 (6), 2013
Background: Cyclodextrin glucanotransferase (CGTase) is one of the most industrially important enzymes used in the commercial production of cyclodextrins (CDs). Alkaliphilic bacteria have attracted much interest in the last few decades because of their ability to produce extracellular enzymes that are ac...
