1. Lingual salivary gland hypertrophy and decreased acinar density in chagasic patients without megaesophagus
ABSTRACT Although the salivary glands present several functions, there are few studies evaluating these glands in Chagas disease (CD). This study aimed to compare the percentage of collagen, the presence of inflammation, the density of chimase and tryptase mast cells, the area and density of lingual salivary gland acini in autopsied individuals with and with

2. Explanation for the signs and symptoms of tooth eruption: mast cells
Resumo Para contribuir com a compreensão dos mecanismos relacionados à sintomatologia e aos sinais associados à erupção dentária, investigou-se a presença de mastócitos nos tecidos pericoronários na fase intraóssea (Grupo 1) e submucosa (Grupo 2), comparando-os entre si e com a mucosa bucal (Grupo 3). Em cada grupo, 14 espécimes foram analisados m

3. Vasoactive intestinal peptide degradation might influence Interleukin-17 expression in cardiac chagasic patients
ABSTRACT The vasoactive intestinal peptide (VIP) expression is lower in cardiac chagasic patients and is related to worse cardiac function. The reduction of VIP in patients with Chagas disease may be a result of its enhanced degradation. To test this hypothesis, the tryptase and chymase expression was evaluated. We also related VIP levels with interleukin-17

4. Histochemical and immunohistochemical differences between solitary oral fibroma and fibrous papule of the face
Abstract: Background: The morphological similarities between fibrous papules of the face and multiple sporadic oral fibromas were mentioned long ago and a relationship between them has been reported in the literature. Objective: The aim of this study was to evaluate the participation of mast cells, elastin and collagen in a series of oral fibromas and fibr

5. Inflammatory response of human dental pulp to at-home and in-office tooth bleaching
ABSTRACT Tooth bleaching is a technique of choice to obtain a harmonious smile, but bleaching agents may damage the dental pulp. Objective: This study evaluated the inflammatory responses of human dental pulp after the use of two bleaching techniques. Material and Methods: Pulp samples were collected from human third molars extracted for orthodontic reason

6. Adult mastocytosis: a review of the Santo António Hospital 's experience and an evaluation of World Health Organization criteria for the diagnosis of systemic disease
BACKGROUND: Mastocytosis is a clonal disorder characterized by the accumulation of abnormal mast cells in the skin and/or in extracutaneous organs. OBJECTIVES: To present all cases of mastocytosis seen in the Porto Hospital Center and evaluate the performance of World Health Organization diagnostic criteria for systemic disease. METHODS: The cases o

7. Stimulated mast cells promote maturation of myocardial microvascular endothelial cell neovessels by modulating the angiopoietin-Tie-2 signaling pathway
Angiopoietin (Ang)-1 and Ang-2 interact in angiogenesis to activate the Tie-2 receptor, which may be involved in new vessel maturation and regression. Mast cells (MCs) are also involved in formation of new blood vessels and angiogenesis. The present study was designed to test whether MCs can mediate angiogenesis in myocardial microvascular endothelial cells

8. ENVOLVIMENTO DE MASTÓCITOS EM UM MODELO DE DOR PÓS-OPERATÓRIA EM CAMUNDONGOS / INVOLVEMENT OF MAST CELLS IN A MODEL OF POSTOPERATIVE PAIN IN MICE
Estudos recentes indicam que praticamente a metade de todos os pacientes submetidos à procedimentos cirúrgicos apresentam um quadro de dor moderada à severa, o que torna importante entender os mecanismos envolvidos na dor pós-operatória para melhor tratá-la. Dados da literatura demonstram que incisões podem causar a degranulação de mastócitos. Assi

9. Renal macrophage infiltration is associated with a poor outcome in IgA nephropathy
OBJECTIVES: The objectives of our study were as follows: 1) to analyze the prognostic value of macrophage infiltration in primary IgA nephropathy (IgAN) and 2) to study the relationship between macrophages and other factors associated with the development of renal fibrosis, including mast cells, TGF-β1, α-SMA and NF-kB. METHODS: We analyzed 62 patients who

11. Inflammatory and Immunological Aspects of pulpitis Human Dental / Aspectos Inflamatórios e Imunológicos de Pulpites Dentárias Humanas
Immune and inflammatory cells may contribute to host defense and microenvironmental changes during the pathogenesis of dental pulpitis. This study evaluated the microscopic characteristics and densities (per mm2) of tryptase+ mast cells, CD4+ T helper lymphocytes, CD45RO+ memory T lymphocytes, foxp3+ T regulatory lymphocytes, CD20+ B lymphocytes, CD68+ macro

12. Expressão Imuno-histoquímica da triptase em mastócitos nos Fibromas de Células Gigantes e Hiperplasias Fibrosas de Mucosa Oral
The giant cell fibroma is a benign neoplasm characterized by the presence of mono, bi or multinucleate cells, which can have a connection to the presence of mast cells. This research aims to analyze, descriptively and comparatively, the immunohystochemistry expression of the tryptase in mast cells of the giant cell f ibroma, f ibrous hyperplasia and samples
