1. Platelet-rich plasma plus bioactive glass in the treatment of intra-bony defects: a study in dogs
OBJECTIVE: This study was designed to evaluate, histomorphometrically, the association of platelet-rich plasma (PRP) and bioactive glass (BG) in the treatment of periodontal intrabony defects. MATERIAL AND METHODS: Nine mongrel dogs were included in the study. Three-wall intrabony defects were surgically created at the mesial and distal aspect of first mandi

2. Alterações no periodonto de proteção e ligamento periodontal em molares de ratos ubmetidos ao etanol durante a lactação: estudo Histopatológico e Histométrico
O alcoolismo é um problema de saúde pública mundial, envolvendo milhares de homens e mulheres, trazendo conseqüências graves como doença em todos os órgãos do corpo do humano, em especial o estômago, o fígado, o coração e o cérebro. O consumo de bebidas alcoólicas por lactantes e lactentes vem despertando a atenção dos pesquisadores, nas últ

3. Interstitial and Langerhans' dendritic cells in chronic periodontitis and gingivitis
The aim of the present study was to compare quantitatively the distribution of dendritic cell subpopulations in chronic periodontitis and gingivitis. Fourteen biopsies from patients with chronic periodontitis and fifteen from patients with gingivitis were studied. An immunoperoxidase technique was used to quantify the number of Langerhans' cells (CD1a) and i

4. The evaluation of connective tissue and platelet-rich plasma (PRP) on the periodontal regenegaration in gingival recession : a histomorphometric study in dogs / Avaliação histometrica da associação do plasma rico em plaquetas com o enxerto de tecido conjuntivo subepitelial em retrações gengivais em cães
The aim of this study was to histometrically evaluate the healing process of gingival recessions treated by PRP in combination with subepithelial connective tissue graft (SCTG) and to compare it to that obtained with SCTG alone (Control). Six mongrel dogs were used in the experiment. Gingival recessions (5x7mm) were surgically created and exposed to plaque a

5. Study of heavy metals commonly used in oral rehabilitation: effects of cobalt over adamantine epithelium, junctional epithelium, inserd gum, and periodontal ligament / Estudo de metais pesados comumente utilizados na reabilitação oral: efeitos do cobalto no epitélio adamantino, epitélio juncional, gengiva inserida e ligamento periodontal
O cobalto é um dos principais componentes das ligas metálicas fundidas amplamente utilizadas na odontologia. Ele é considerado o constituinte de 45 a 70% de inúmeros trabalhos protéticos. Há evidência de elementos metálicos causarem toxicidade sistêmica e local. Este trabalho teve como objetivo, avaliar os efeitos do cobalto no epitélio juncional,

6. Regeneração tecidual guiada com membranas reabsorviveis em retrações gengivais : estudo histometrico em cães
The goal of this investigation was to evaluate histologically and histometrically the healing process of gingival recessions treated by guided tissue regeneration with polylactic acid membranes (GTR-group) and to compared it to that obtained with coronally positioned flaps (CPF-group). Five mongrel dogs were used in the experiment. Gingival recessions were s

7. Analise imunohistoquimica e ultraestrutural da gengiva da face distal do incisivo inferior de rato
The continuous growth of the rat incisor is associated with a constant reorganization of the junctional epithelium. The gengiva of the rat incisor presents the circundental papilla, corresponding to a projections of the sulcular epithelium in to the subjacent connective tissure. The internal surface os the circundental papilla contacts the cervical part of t

8. O desenvolvimento do processo inflamatorio no tecido gengival de rato
The dynamic and composition of the gingival fluid has been studied by various authors, but little is known about the vessels involved in its formation during the junctional epithelium organization. This study describes the gingival inflammatory process, especially the increased vascular permeability, during the development of the gingiva of rats. Rats, 19 to

9. Development of Junctions During Differentiation of Lens Fibers
Throughout the differentiation of eye lens epithelium into fibers, an extensive system of intercellular junctions develops. The junctional assembly is initially characterized by the accumulation of 9.0-nm intramembranous particles, forming linear rows in the matching plasma membranes of adjoining fibers. At the final stage of the fiber differentiation, the j

10. Lipopolysaccharide-Induced Epithelial Monoamine Oxidase Mediates Alveolar Bone Loss in a Rat Chronic Wound Model
Reactive oxygen species (ROS) production is an antimicrobial response to pathogenic challenge that may, in the case of persistent infection, have deleterious effects on the tissue of origin. A rat periodontal disease model was used to study ROS-induced chronic epithelial inflammation and bone loss. Lipopolysaccharide (LPS) was applied for 8 weeks into the gi

11. Diversity in T-cell receptor gamma gene usage in intestinal epithelium.
The intraepithelial cells of the murine small intestine include a significant number of CD3+ T cells that use T-cell receptor gamma genes rather than T-cell receptor beta genes. As with other sites of T-cell receptor gamma expression, combinatorial diversity is limited, but there is junctional diversity, and this, together with the specific variable region g

12. Expression of Podocalyxin Inhibits Cell–Cell Adhesion and Modifies Junctional Properties in Madin-Darby Canine Kidney Cells
Podocalyxin is a major membrane protein of the glomerular epithelium and is thought to be involved in maintenance of the architecture of the foot processes and filtration slits characteristic of this unique epithelium by virtue of its high negative charge. However, until now there has been no direct evidence for podocalyxin's function. Podocalyxin is a
