Abstract The present study evaluated the odontogenic potential of human dental pulp cells (HDPCs) exposed to chitosan scaffolds containing calcium aluminate (CHAlCa) associated or not with low doses of simvastatin (SV). Chitosan scaffolds received a suspension of calcium aluminate (AlCa) and were then im...

The use of specially designed wound dressings could be an important alternative to facilitate the healing process of wounds in the hyperglycemic state. Biocompatible dressings combining chitosan and alginate can speed up wound healing by modulating the inflammatory phase, stimulating fibroblast prolifera...

The aim of this study was to develop a chitosan biofilm against Salmonella enteritidis, for the conservation of fertile and table eggs. Two experiments were performed. Experiment 1: 400 specific pathogen-free table eggs were divided in a completely randomized design into four treatments, five replicates ...
This study aimed to evaluate the effects of increasing levels of chitosan (CHI) on sugarcane fermentation profile and losses, chemical composition, and in situ degradation. Treatments were: 0, 1, 2, 4, and 8 g of CHI/kg of dry matter (DM). Twenty experimental silos (PVC tubing with diameter 28 cm and hei...
A composição e arquitetura das matrizes desempenham um papel importante na regeneração tecidual, e a interação entre seus componentes pode influenciar no desenvolvimento celular. Assim, o objetivo do presente estudo foi desenvolver e analisar as características morfológicas, físico-químicas, bi...
O objetivo neste estudo foi produzir hidrogel de quitosana (CH) com PCL e
fitoterápicos para uso preventivo de úlcera de pressão. Os hidrogéis de CH foram
produzidos com glicerofosfato (GP) e com xantana (X), associados ao PCL e foram
caracterizados por estereomicroscopio, intumescimento, molhabilida...
Os cimentos dentários e ortopédicos são utilizados amplamente em diversas
aplicações clínicas. Novos cimentos vêm sendo propostos visando à preservação ou
regeneração tecidual. Contudo, pouco se conhece sobre o papel desses
biomateriais na regeneração nervosa. As células mais comumente env...
Abstract Purpose To evaluate different concentrations of ciprofloxacin to prevent infection after open fracture contaminated with S. aureus in rats using absorbable local delivery system. Methods Fifty-two Wistar rats were assigned to six groups. After 4 weeks, all animals underwent 99mTc-ceftizoxima...

Abstract This research aims to determine the efficiency of chitosan and xanthan gum films in conservation of croaker fillets kept in refrigeration for 9 days. Proximal composition, loss of mass, color, pH, TVB-N (Total Volatile Bases) and microbiological profile were assessed. The films were prepared wit...
