Valuation of angiogenesis in bovine xenografts implanted in intracorporal sites of rabbits as models of in-vivo bioreactors

The aim of this study was to evaluate neovascularization of bovine xenografts implanted in intracorporeal sites of rabbits (bioreactors). 30 rabbits were used, divided into 6 groups, according to the evaluation time (7, 15, 30, 45, and 60 days); each animal received xenogenic implants in 3 different intr...

Cambios Dimensionales en Técnicas de Preservación Alveolar Bartee y Bio-Col con Xenoinjerto Inteross®

La preservación de las dimensiones y contorno del reborde alveolar posterior a una extracción es de suma importancia para evitar problemas subsecuentes para la colocación de un implante dental. El objetivo de este estudio fue comparar los cambios dimensionales mediante el análisis en tomografía comp...

Expression of CD44 in previously grafted alveolar bone

J. oral res. (Impresa); 9 (6), 2020
Objetive: To determine the expressions of the bone surface marker CD44 in samples of alveolar bone previously regenerated with allograft, xenograft, and mixed, using the technique of guided bone regeneration. Material and Methods: This exploratory study was approved by the institutional research and ethi...

Establishment of a simple and efficient platform for car-t cell generation and expansion: from lentiviral production to in vivo studies

ABSTRACT Introduction: Adoptive transfer of T cells expressing a CD19-specific chimeric antigen receptor (CAR) has shown impressive response rates for the treatment of CD19 + B-cell malignancies in numerous clinical trials. The CAR molecule, which recognizes cell-surface tumor-associated antigen indepen...

Caprine demineralized bone matrix (DBMc) in the repair of non-critical bone defects in rabbit tibias. A new bone xenograft

Acta cir. bras; 35 (8), 2020
Abstract Purpose To evaluate the use of demineralized bone matrix of caprine origin in experimental bone defects of the tibia in New Zealand rabbits. Methods Fragments of the tibia diaphysis were collected aseptically from clinically healthy goats. The bones were sectioned into 1 cm fragments and sto...

Repair of critical size bone defects using synthetic or bovine hydroxyapatite with or without bone marrow mononuclear fraction: histomorphometric and immunohistochemical analysis

O presente trabalho teve como objetivo avaliar a regeneração óssea de defeitos ósseos críticos na calvária de ratos com a utilização de enxerto xenógeno Bio-Oss Small ( Bio-Oss® Geistlich Pharma AG, Wolhusen, Suíça) e hidroxiapatita sintética, (Alobone poros Osseocon Biomateriais Ltda., Rio ...

A study of the effects of imidacloprid under laboratory and field conditions on nymphs of Triatoma infestans (Hemiptera: Reduviidae)

Vet. parasitol; 280 (), 2020
The aim of this study was to determine imidacloprid’s lethal activity against fifth-instar nymphs of Triatoma infestans. In the first stage of this work, it was assayed the topical application of this insecticide on non-fed and repletion-fed nymphs. Results showed a DL50 three times greater in non-fed ...
