Effective Inhibition of TNFalpha/mTOR Axis-Mediated Liver Inflammation and Fibrosis Induced by TAA Using a Combination of Metformin and Resveratrol in Association with the Inhibition of the Profibrotic Gene and Protein Expression

Int. j. morphol; 42 (2), 2024
SUMMARY: The response of the immune system to harmful stimuli leads to inflammation, and the adverse effects of the toxic hepatitis chemical, thioacetamide (TAA) on the human body are well documented. This article investigated the degree of protection provided by the combined pleotropic drug, metformin (...

Preclinical evaluation of the functionality of a polymer-coated sirolimuseluting stent in pigs

Acta cir. bras; 39 (), 2024
Purpose: To compare the endothelial coverage of different stents in porcine carotid arteries. Research problem: How effective are polyurethane stents (PU) and PU + rapamycin (PU + RAPA) compared to bare-metal stents on endothelial coverage by neointima in pigs after 28 days? Methods: The methodology had...

O efeito do tratamento com rapamicina em órgãos linfoides de camundongos propensos à senescência acelerada

Envelhecer compreende um fenômeno complexo, natural e irreversível, que submete o organismo a inúmeras alterações nos processos biológicos, fisiológicos, ambientais, psicológicos, comportamentais e sociais. Esse processo é caracterizado por um declínio gradual dos mecanismos homeostáticos do o...

Use of sirolimus and sclerotherapy for lymphatic malformations in a developing country: a case series

Las malformaciones linfáticas y su manejo no han sido bien descritas en República Dominicana. Es por ello, que el objetivo de este artículo es la presentación de tres casos, con diferentes patrones y necesidades de tratamiento, de modo que sirva como referencia para trabajadores de la salud en paíse...

Linfangiomatosis pulmonar difusa con compromiso pleural y pericárdico. Reporte de un caso pediátrico

Arch. argent. pediatr; 119 (3), 2021
La linfangiomatosis pulmonar difusa es una enfermedad rara caracterizada por una marcada proliferación y dilatación de los vasos linfáticos en los pulmones, la pleura y el mediastino. Se desconoce la prevalencia, y la etiología no se comprende completamente.Una niña de 22 meses ingres...

The effects of rapamycin and 3-methyladenine on nitric oxide synthase enzymes in cisplatin-induced neurotoxicity

Int. j. morphol; 39 (2), 2021
SUMMARY: The aim of this study was to determine the relationship of autophagy-enhancing rapamycin (RAPA) and autophagy- inhibitor 3-methyladenine (3-MA) with Nitric oxide synthases (NOS) in Cisplatin (CIS)-induced neurotoxicity in rats. Rats were divided into 4 groups (n=10): Control was applied saline, ...

Autophagy activation attenuates the neurotoxicity of local anesthetics by decreasing caspase-3 activity in rats

Rev. bras. anestesiol; 70 (6), 2020
Abstract Background and objectives The mechanisms by which local anesthetics cause neurotoxicity are very complicated. Apoptosis and autophagy are highly coordinated mechanisms that maintain cellular homeostasis against stress. Studies have shown that autophagy activation serves as a protective mechanis...

Design, manufacture and initial tests of a drug-eluting coronary stent

Gac. méd. Méx; 156 (4), 2020
Abstract Introduction: A drug-eluting coronary stent is being developed at the National Institute of Cardiology of Mexico for the treatment of ischemic heart disease. Objective: To establish the best animal model for the tests, to show the advances in the drug-eluting stent prototype, to assess two dru...

Effects of ICI 182, 780, an ERα and ERβ antagonist, and G-1, a GPER agonist, on autophagy in breast cancer cells

ABSTRACT Objective To investigate if ICI 182,780 (fulvestrant), a selective estrogen receptor alpha/beta (ERα/ERβ) antagonist, and G-1, a selective G-protein-coupled receptor (GPER) agonist, can potentially induce autophagy in breast cancer cell lines MCF-7 and SKBr3, and how G-1 affects cell ...
