Histomorphological, Histochemical and Ultrastructural Studies on the Healthy Liver of Yemen Veiled Chameleon (Chamaeleo calyptratus) in Southern Saudi Arabia

Int. j. morphol; 41 (5), 2023
SUMMARY: The livers of reptiles are being studied as a model for the link between the environment and hepatic tissue. There have been few investigations on the histology of reptile livers, and very few or no studies have examined the histology of liver of veiled chameleon (Chamaeleo calyptratus). This pa...

Avaliação do comportamento das fibras colágenas periodontais durante a progressão da periodontite experimental em ratos

Introdução: A periodontite é uma doença infecto-inflamatória, resultante da disbiose microbiana e da resposta do hospedeiro, que leva à destruição dos tecidos de suporte dentário, inclusive das fibras colágenas periodontais, podendo culminar na perda do elemento dental. Objetivo: Avaliar o com...

Hybrid Verrucous Carcinoma: a Wolf in Sheep's Clothing Case Report and Integrative Review of 280 Cases

ABSTRACT: Hybrid verrucous carcinoma (HVC) is defined as a rare neoplasm in which there is histopathological evidence of verrucous carcinoma and microscopic foci of squamous cell carcinoma, synchronously in the same site, affecting behavior and prognosis. This study aimed to present a new case of HVC in ...

Effect of Titanium Hardness on the Integrity and Stress Concentration of External Hexagon Dental Implants

The aim of this study was to evaluate the influence of overtorque on integrity, strength and stress on external hexagonal implants (EH), with two different grades (N=10): conventional (C), grade 4; and modified (M), grade 4 with thermal treatment. The dimensions of EH were 3.75 x 13 mm; the specimens wer...

¿Los Quistes Periradiculares Dependen de la Infección Endodóntica?

Los quistes periradiculares, tanto los de bolsillo como los verdaderos, son de origen inflamatorio; sin embargo, en la literatura ha existido una gran controversia asociada, en primer lugar, a la dependencia de la infección contenida dentro del sistema de conductos radiculares y, en segundo lugar, al ti...

Liver structural injury in leptin-deficient (ob/ob) mice: lipogenesis, fibrogenesis, inflammation, and apoptosis

Int. j. morphol; 39 (3), 2021
SUMMARY: Nonalcoholic fatty liver disease (NAFLD) might progress the steatosis to nonalcoholic steatohepatitis (NASH), reaching a cirrhosis state and possibly hepatocellular carcinoma. The liver of three-month-old C57BL/6J mice (wild-type, WT group, n=10) and leptin- deficient obese mice (ob/ob group, n=...

Evaluation of tensile strength after insertions andremovals of abutments on frictional Morse taper implants

This study aimed to evaluate possible changes in final retention after nine sequences of insertion and removal (SIR) of a frictional Morse taper implant/abutment system, evaluating the force required for dissociating this set between sequences, and verifying possible deformations in the implant heads. Te...

Detección y cuantificación de células plasmáticas (plasmocitos) en granulomas periapicales inducidos experimentalmente en ratas
Detection and quantification of plasma cells in experimentally induced rat periapical granulomas

Objetivo: En los granulomas periapicales, los plasmocitos (PL) participan activamente mediante la liberación de inmunoglobulinas. El propósito de este ensayo fue identificar y contar el número de PL en diferentes períodos de tiempo en lesiones periapicales experimentales en ratas. Materiales y métod...
