Expressão de e-caderina e claudina-3 no epitélio cólico após terapia com infliximabe: modelo experimental de colite de exclusão

ABCD (São Paulo, Impr.); 34 (4), 2021
RESUMO - RACIONAL: A etiopatogenia da colite por desuso (DC) ainda não foi totalmente elucidada. As principais teorias consideram que a doença pode estar relacionada ao aumento de bactérias anaeróbias, falta de suprimento de ácidos graxos de cadeia curta (AGCC) e distúrbios imunológicos que se des...

Variante patogénica en el gen PCDH19 en una paciente con epilepsia y discapacidad cognitiva

Rev. chil. pediatr; 91 (5), 2020
INTRODUCCIÓN: La asociación de casos familiares de epilepsia y discapacidad intelectual (DI) en mujeres fue reportada en 1971. El año 2008, se identificó el rol de variantes patogénicas del gen PCDH19 en algunas familias. La enfermedad se presenta con crisis febriles en cluster, DI y rasgos autista...

Transcriptome profile of highly osteoblastic/cementoblastic periodontal ligament cell clones

J. appl. oral sci; 28 (), 2020
Abstract Heterogeneous cell populations of osteo/cementoblastic (O/C) or fibroblastic phenotypes constitute the periodontal dental ligament (PDL). A better understanding of these PDL cell subpopulations is essential to propose regenerative approaches based on a sound biological rationale. Objective Our...

Upregulation of intercellular adhesion molecule-1 and vascular cell adhesion molecule-1 in renal tissue in severe dengue in humans: Effects on endothelial activation/dysfunction

Abstract INTRODUCTION: Dengue is an important mosquito-borne disease in tropical and subtropical regions. Adhesion molecules have not been systematically characterized in the renal tissue of patients with severe dengue (SD). The objective of this study was to detect viral antigens in samples from patie...

Beneficial effects of Oltipraz, nuclear factor - erythroid - 2 - related factor 2 (Nrf2), on renal damage in unilateral ureteral obstruction rat model

Int. braz. j. urol; 44 (6), 2018
ABSTRACT Introduction: We investigated whether Oltipraz (OPZ) attenuated renal fibrosis in a unilateral ureteral obstruction (UUO) rat model. Materials and Methods: We randomly divided 32 rats into four groups, each consisting of eight animals as follows: Rats in group 1 underwent a sham operation and ...

Identification of a subtype of poorly differentiated invasive ductal carcinoma of the breast based on vimentin and e-cadherin expression

Abstract Objective The use of molecular markers can identify a subgroup of tumors with distinct recurrence patterns. The present study aimed to characterize the immunohistochemical expression of vimentin (VIM), of E-cadherin (CDH1), and of cytokeratin 5 (CK5) in patients with invasive ductal carcinomas...

Saquinavir plus methylprednisolone ameliorates experimental acute lung injury

Braz. j. med. biol. res; 51 (10), 2018
Glucocorticoid insensitivity is an important barrier to the treatment of several inflammatory diseases, including acute lung injury (ALI). Saquinavir (SQV) is an inhibitor of the human immunodeficiency virus protease, and the therapeutic effects of SQV in ALI accompanied with glucocorticoid insensitivity...

Expression of E-cadherin, Slug and NCAM and its relationship to tumor invasiveness in patients with acromegaly

Braz. j. med. biol. res; 51 (2), 2018
Pituitary adenomas account for 10-15% of primary intracranial tumors. Growth hormone (GH)-secreting adenomas account for 13% of all pituitary adenomas and cause acromegaly. These tumors can be aggressive, invade surrounding structures and are highly recurrent. The objective of this study was to evaluate ...

Imunomarcação da transição epitélio-mesenquima na neoplasia mamária primária de cadelas e sua metástase em linfonodo

Pesqui. vet. bras; 37 (12), 2017
Os carcinomas mamários em cães apresentam alta capacidade metastática o que confere menor sobrevida para os pacientes com este tipo de neoplasia. O fenótipo transição epitélio-mesênquima, caracterizado pela troca dos filamentos intermediários de citoqueratina por vimentina, além da perda da pro...

Hypotrichosis with juvenile macular dystrophy: a case report with molecular study

Arq. bras. oftalmol; 80 (1), 2017
ABSTRACT Hypotrichosis with juvenile macular dystrophy is a rare autosomal recessive disorder characterized by sparse scalp hair caused by hair follicle abnormalities as well as progressive retinal degeneration leading to blindness in the second or third decade of life. It is associated with mutations of...
