Resistance training with blood flow restriction and cognition in elderly women (project "forte-mente-ativa"): study protocol

Motriz (Online); 27 (), 2021
Abstract Aim: In the process of aging, there is a decrease on muscle strength and cognitive function. Resistance training combined with blood flow restriction (BFRRT) has been shown capable of maintaining or improve aspects of physical health. However, the effects of BFRRT the cognitive function of the ...

Remodelado cardíaco en el modelo preclínico de falla cardíaca isquémica experimental por dislipidemia en el ratón SR-B1 KO/ApoER6 1h/h

Rev. chil. cardiol; 39 (1), 2020
INTRODUCCIÓN: Los ratones SR-B1 KO/ApoER6 1h/h que son alimentados con una dieta rica en grasas saturadas, desarrollan enfermedad coronaria aterosclerótica severa, complicaciones isquémicas e insuficiencia cardíaca, con alta mortalidad. Los estudios con este modelo se han enfocado fundamentalmente e...

Cirugía de hombro en posición silla de playa: estrategias y recomendaciones para la prevención de complicaciones isquémicas

Rev. chil. anest; 49 (1), 2020
Beach chair position is require for Shoulder surgery frequently for proper resolution. The stroke associated with shoulder surgery is a rare complication and probably underreported. The objective of this article is to review the pathophysiology of the ischemic damage associated with beach chair position,...

TLR7 mediates increased vulnerability to ischemic acute kidney injury in diabetes

SUMMARY OBJECTIVE Diabetes is a risk factor for acute kidney injury (AKI). However, its mechanism of pathogenesis has not been elucidated. The aim of the study was to investigate the role of inflammation and the toll-like receptor 7 (TLR7) in ischemic AKI for diabetes. METHODS A high glucose hypoxia-...

Revisión Bibliográfica: Glicocálix Endotelial como Blanco de Agresión del Fenómeno Isquemia Reperfusión

El glicocálix endotelial es una estructura rica en glucosaminoglicanos, proteoglicanos y glucoproteínas que recubre el endotelio vascular; además de ser una estructura de protección, al estar en contacto directo con la sangre se convierte en el blanco de agresión de diversos mecanismos fisiopatológ...

Ischemic preconditioning delays the time of exhaustion in cycling performance during the early but not in the late phase

Motriz (Online); 25 (1), 2019
Aims: To investigate the early and late ischemic preconditioning (IPC) effect on the trained cyclists’ performance during incremental cycling test until exhaustion. Methods: Twenty-one male cyclists allocated to an IPC (2 x 5-min of blood flow occlusion at 50 mm Hg above systolic pressure followed +...

Liver ischemia and reperfusion injury. Pathophysiology and new horizons in preconditioning and therapy

Acta cir. bras; 33 (8), 2018
Abstract It is well known that during hepatic operative procedures, it is often critical that the irrigation is interrupted to avoid possible bleeding, blood transfusions, variable intensities, and their short and long-term consequences. It was believed in the past that the flow interruption should not e...

Repeatability of the "flash-replenishment" method in contrast-enhanced ultrasound for the quantitative assessment of hepatic microvascular perfusion

Braz. j. med. biol. res; 51 (4), 2018
This study aimed to evaluate the feasibility and repeatability of the flash-replenishment method in contrast-enhanced ultrasound (CEUS) perfusion imaging and assess quantitatively microvascular perfusion in the liver. Twenty healthy New Zealand rabbits were submitted to CEUS perfusion imaging with contin...

Nephrometry scores and perioperative outcomes following robotic partial nephrectomy

Int. braz. j. urol; 43 (6), 2017
ABSTRACT Objectives: Based on imaging features, nephrometry scoring systems have been conceived to create a standardized and reproducible way to characterize renal tumor anatomy. However, less is known about which of these individual measures are important with regard to clinically relevant perioperativ...

Mistura de Ácido Gálico e Ciclosporina e seus Efeitos sobre a Disfunção Cardíaca Induzida pela Isquemia / Reperfusão e Expressão de eNOS/iNOS

Fundamento: Embora muitas pesquisas tenham sido conduzidas com um determinado antioxidante ou mPTP individualmente, pouca atenção tem sido dada para os efeitos da co-administração de um antioxidante e um inibidor de mPTP sobre a disfunção cardíaca após a lesão de I/R. Objetivos: Este estudo obje...
