Oral lichen planus in a young patient: a case report with nine-year follow-up

ABCS health sci; 48 (), 2023
INTRODUCTION: Oral lichen planus is an inflammatory condition that affects the stratified squamous epithelium of the oral mucosa. It occurs more frequently in female patients and it is rarely observed in children, adolescents, or young adults. This study aims to report a case of oral lichen planus in a y...

Expression and distribution of kallikrein-related peptidases 5, 7, 8 and 10 in normal apocrine gland of canine skin

Int. j. morphol; 41 (1), 2023
SUMMARY: Apocrine glands are sweat glands that are located in the skin of the dog. Anal sac apocrine, circunanal apocrine, and mammary glands are considered modified apocrine structures, and there are about nine possible types of neoplasms and other tumors in the apocrine glands of the dog and cat, inclu...

Distribution of calcitonin gene-related peptide and vascular endothelial growth factor in the mouse lung at the embryonic and postnatal stages

Int. j. morphol; 41 (1), 2023
SUMMARY: Neuropeptide calcitonin gene-related peptide (CGRP) is a neurotransmitter related to vasculogenesis during organ development. The vascular endothelial growth factor A (VEGF-A) is also required for vascular patterning during lung morphogenesis. CGRP is primarily found in organs and initially appe...

Immunohistochemical evidence of melatonin protection on lung tissue during chemotherapy

Int. j. morphol; 41 (1), 2023
SUMMARY: The present study investigated the possible protective effects of melatonin on Bleomycin, Cisplatin and etoposide (BEP) chemotherapy regimens using immunohistochemistry. Forty male Wistar rats were divided into four groups of ten as; group 1 as untreated control; group 2 as BEP group which recei...

Structure and function adaption of lung in Phrynocephalus vlangalii by multiple mechanisms

Int. j. morphol; 41 (1), 2023
SUMMARY: Respiration and water-liquid transportation are controlled by many factors in the lung. The aim of this study was to explore the structure and proteins expression in lungs of Phrynocephalus vlangalii by means of gross anatomy, light microscope observation, scanning electron microscope and immuno...

Radicular cyst in primary dentition showing angiolymphoid hyperplasia with eosinophilia (ALHE)-like features: An immunohistochemical study

J. Oral Diagn; 8 (), 2023
The microscopical diagnosis of radicular cyst (RC) is straightforward; nonetheless, in some cases with unusual histopathological features, strict clinicopathological correlation is necessary to achieve the correct diagnosis. We report a case of a 5-year-old girl was referred presenting exten...

Gastroesophageal tube of the Iguana iguana (Iguanidae): histological description, histochemical and immunohistochemical analysis of 5-HT and SS cells

Braz. j. biol; 83 (), 2023
Abstract The work aims were to describe the histological and histochemical structure of the gastroesophageal tube of Iguana iguana and verify the occurrence and distribution of immunoreactive serotonin (5-HT) and somatostatin (SS) cells. Fragments of the gastrointestinal tract (GIT) of five iguanas were ...

Effect of Thymoquinone on skeletal muscle regeneration via assessment of Pax-7 and Myo-D expression in the DMBA-treated hamster pouch

Braz. dent. sci; 26 (2), 2023
Objective: Pax-7 and Myo-D regulate satellite cells’ activation and differentiation, thus muscle regeneration following damage. This research aimed to investigate the effect of Thymoquinone (TQ) on skeletal muscle regeneration following 7,12-dimethylbenz-(a)-anthracene (DMBA...

Biochemical and immunohistochemical examination of the effects of ephedrine in rat ovary tissue

Acta cir. bras; 38 (), 2023
Purpose: It was aimed to investigate the biochemical and immunohistochemical effects of ephedrine (EPH) in bilateral ovariectomized rats. Methods: Twenty-four Sprague Dawley female rats were divided into three groups: control group: The abdomen was opened and closed without any treatment; ischemia-reperf...

Histopathological, ultrastructural, and immunohistochemical examination of changes in the placenta as a result of severe preeclampsia

Acta cir. bras; 38 (), 2023
Purpose: To investigate the role of hypoxia-inducible transcription factor-1 alpha (HIF-1α) and angiogenetic factor endothelin-1 (ET-1) expression in regulating hypoxia and placental development by routine histopathological methods. Methods: Twenty preeclamptic and normal placentas were used. Placenta t...
