Hipertensión pulmonar: señalización mediada por canales de calcio, dianas farmacológicas presentes y futuras

Rev. méd. Chile; 151 (6), 2023
La hipertensión arterial pulmonar se caracteriza por una presión arterial pulmonar media y resistencia vascular pulmonar elevadas y remodelado patológico de las arterias pulmonares. La entrada de calcio desde el espacio extracelular al intracelular a través de canales dependientes e independientes de...

Avaliação farmacológica de novos derivados n-acilidrazônicos em modelo animal de hipertensão arterial sistêmica
Pharmacological evaluation of new n-acylhydrazonic derivatives in an animal model of systemic arterial hypertension

Introdução: A hipertensão arterial sistêmica é uma condição multifatorial e considerada fator de risco para disfunção cardíaca, encefálica, renal. A busca por novas estratégias de prevenção e tratamento de doenças cardiovasculares levou ao planejamento e síntese de novas N-acilidrazonas p...

Canales de calcio como blanco de interés farmacológico

NOVA publ. cient; 18 (34), 2020
Resumen Los canales de calcio son proteínas de membrana que constituyen la vía más importante para el ingreso del ion calcio (Ca2+) a la célula. Al abrirse, permiten el ingreso selectivo del ion, iniciando una variedad de procesos como contracción muscular, secreción endocrina y liberación de neur...

The mitochondrial calcium uniporter: a new therapeutic target for Parkinson's disease-related cardiac dysfunctions?

Clinics; 75 (), 2020

Cardioprotective effects of pharmacological blockade of the mitochondrial calcium uniporter on myocardial ischemia-reperfusion injury

Acta cir. bras; 35 (3), 2020
Abstract Purpose To evaluate whether the attenuation of mitochondrial Ca2+ overload produced by pharmacological blockade of mitochondrial Ca2+ uniporter (MCU) protects the myocardium against injuries caused by cardiac ischemia and reperfusion (CIR). Methods CIR was induced in adult male Wistar rats (...

Discovery of the ARP2 protein as a determining molecule in tumor cell death

Gac. méd. Méx; 155 (5), 2019
Cancer is a multifactorial disease that constitutes a serious public health problem worldwide. Prostate cancer advanced stages are associated with the development of androgen-independent tumors and an apoptosis-resistant phenotype that progresses to metastasis. By studying androgen-independent lymphoid n...

Resveratrol reduces store-operated Ca2+ entry and enhances the apoptosis of fibroblast-like synoviocytes in adjuvant arthritis rats model via targeting ORAI1-STIM1 complex

Biol. Res; 52 (), 2019
BACKGROUND: Resveratrol was reported to trigger the apoptosis of fibroblast-like synoviocytes In adjuvant arthritis rats but the subcellular mechanism remains unclear. Since ER stress, mitochondrial dysfunction and oxidative stress were involved in the effects of resveratrol with imbalance of calcium bio...

From echocardiographic evaluation to biomarkers measurement: the role of myocardial dysfuction in mortality associated with sepsis

Sepsis remains the leading cause of mortality and critical illness worldwide. Myocardial dysfunction is one of the most clinically relevant manifestations of sepsis and results from a complex interaction among genetic, molecular, metabolic, and structural changes. Despite the prominence given to the occu...

Subclinical intramammary infection does not affect bovine milk ethanol stability

The present study hypothesized that intramammary infection (IMI) might reduce milk ethanol stability (MES), mainly when IMI is caused by major pathogens. Thus, this study evaluated the effect of IMI on bovine MES using a natural exposure experimental design. Ninety-four lactating cows from five dairy her...
