The long non-coding RNA H19 induces hypoxia/reoxygenation injury by up-regulating autophagy in the hepatoma carcinoma cells

Biol. Res; 52 (), 2019
BACKGROUND: Long non-coding RNA H19 (H19) plays an important role by regulating protein expression in different tissues and organs of the body. However, whether H19 induces hypoxia/reoxygenation (h/R) injury via increase of autophagy in the hepatoma carcinoma cells is unknown. RESULTS: H19 was expressed ...

Oxidative stress assessment in intestine of newborn rats submitted to hypoxia and reoxygenation with tadalafil

Acta cir. bras; 34 (4), 2019
Abstract Purpose: To evaluate the functional and structural response of tadalafil effects in the intestinal mucosa, using an experimental model of hypoxia and reoxygenation injury in rats. Methods: The animals were divided into 4 groups: CTL, H/R, H/R+Td and M+Td. The newborn rats allocated in groups ...

Fístula arteriovenosa pós-cateterismo radial com repercussões cardiopulmonares

O presente artigo relata o caso de um paciente coronariopata de 86 anos submetido a cateterismo cardíaco via acesso radial à esquerda. Cerca de 16 meses após o procedimento, manifestou dispneia sem relação com esforço, associada a hipóxia noturna. Apresentava frêmito à palpação do punho esquer...

Structural, histochemical and photosynthetic profiles of galls induced by Eugeniamyia dispar (Diptera: Cecidomyiidae) on the leaves of Eugenia uniflora (Myrtaceae)

Rev. biol. trop; 66 (4), 2018
Abstract Gall-inducing insects manipulate the structural, histochemical and physiological profiles of host-plant tissues to develop galls. We evaluated galls induced by Eugeniamyia dispar on the leaves of Eugenia uniflora in an attempt to answer the following questions: (i) How does this gall-inducing in...

Relevancia de la detección de cardiopatías congénitas complejas mediante cribado con oximetría de pulso en recién nacidos aparentemente sanos en los establecimientos de salud

Arch. cardiol. Méx; 88 (4), 2018
Resumen Se trata de un estudio de revisión de datos publicados en literatura médica relacionada con el cribado usado para la detección temprana de cardiopatías congénitas complejas en recién nacidos aparentemente sanos en diversas ciudades del mundo, incluyendo los reportados en México, desde aque...

Intermittent hypoxia, brain glyoxalase-1 and glutathione reductase-1, and anxiety-like behavior in mice

Objective: Sleep apnea has been associated with anxiety, but the mechanisms of the sleep apnea-anxiety relationship are unresolved. Sleep apnea causes oxidative stress, which might enhance anxiety-like behavior in rodents. To clarify the apnea-anxiety connection, we tested the effect of intermittent hypo...

Maximum effort training performed in hypoxia alters the mood profile

Rev. bras. med. esporte; 24 (6), 2018
INTRODUCTION: Physical exercise at high altitude has become constant. However, the risks associated with this type of exercise represent a major concern, considering the influence of important stressors such as hypoxia and physical exercise on psychobiological and physiological responses. OBJECTIVE: Anal...

Impact of adherence to long-term oxygen therapy on patients with COPD and exertional hypoxemia followed for one year

J. bras. pneumol; 44 (5), 2018
ABSTRACT Objective: To determine the impact of adherence to long-term oxygen therapy (LTOT) on quality of life, dyspnea, and exercise capacity in patients with COPD and exertional hypoxemia followed for one year. Methods: Patients experiencing severe hypoxemia during a six-minute walk test (6MWT) perfo...

Relación entre la saturación central venosa de oxígeno >_ 70% y la mortalidad en el choque séptico

Estado nutricional, composición corporal e indicadores antropométricos de trabajadores mineros expuestos a hipoxia hipobárica crónica e intermitente a una altitud moderada (0-2500 msnm)

Rev. chil. nutr; 45 (3), 2018
RESUMEN Introducción En Chile, los trabajadores mineros están expuestos a condiciones laborales y ambientales particulares. Sin embargo, la normativa actual no considera estas condicionantes para evaluar el estado nutricional y riesgo cardiovascular de esta población. Objetivo Describir indicadores ...
