Abstract Introduction Postoperative dysphonia is mostly caused by vocal fold scarring, and careful management of vocal fold surgery has been reported to reduce the risk of scar formation. However, depending on the vocal fold injury, treatment of postoperative dysphonia can be challenging. Objective The...
ABSTRACT Purpose: To compare biological compatibility, hemostasis, and adhesion formation between oxidized regenerated cellulose and lyophilized hydrolyzed porcine collagen in liver trauma. Methods: Forty male Wistar rats constituted two groups: group A (oxidized cellulose) and group B (lyophilized hyd...
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...
Abstract Background and objectives Modern crystalloid and colloid solutions are balanced solutions which are increasingly used in perioperative period. However, studies investigating their negative effect on whole blood coagulation are missing, and vivid debate is going on about which solution has the m...

Trauma or disease inflicted by tissue injuries may cause tissue degeneration. The use of biomaterials for direct or indirect repair has emerged as a promising alternative, and has become an important research topic. The pequi fruit (Caryocar brasiliense Camb.) has shown antifungal, antibacterial, anti-in...
Abstract INTRODUCTION: Appropriate preservation of specimens is important for taxonomic identification. In sandfly research, various methods have been used for slide preparation; however, high cost, low commercial availability, and associated hazards make their use impossible in some studies. Therefore...
ABSTRACT Background Obtaining effective hemostasis either in the traumatic or surgical lesions of parenchymal viscera, especially the liver, has always been a challenge. Aim: Comparative study between the use of different hemostatic sponges in hepatic wound and their capacity of integration to cells i...
ABSTRACT This paper describes the preparation and characterization of alginate beads coated with gelatin and containing Lactobacillus rhamnosus. Capsules were obtained by extrusion method using CaCl2 as cross linker. An experimental design was performed using alginate and gelatin concentrations as the va...
ABSTRACT Enzymatically crossliked gelatin hydrogel was submitted to two different drying methods: air drying and freeze drying. The resulting polymeric tridimensional arrangement (compact or porous, respectively) led to different thermal and swelling properties. Significant differences (p < 0.05) on t...
