Improvement of endothelial function by Gunnera tinctoria extract with antioxidant properties

Biol. Res; 53 (), 2020
BACKGROUND: Gunnera tinctoria has been collected by Mapuche-Pewenche people for food and medicinal purposes. The high polyphenol content of methanolic extract from G. tinctoria leaves with chemical constituents such as ellagic acid and quercetin derivatives suggests its application to prevent endothelial...

Tauroursodeoxycholic acid attenuates neuronal apoptosis via the TGR5/ SIRT3 pathway after subarachnoid hemorrhage in rats

Biol. Res; 53 (), 2020
BACKGROUND: Neuronal apoptosis plays a critical event in the pathogenesis of early brain injury after subarachnoid hemorrhage (SAH). This study investigated the roles of Tauroursodeoxycholic acid (TUDCA) in attenuate neuronal apoptosis and underlying mechanisms after SAH. METHODS: Sprague-Dawley rats wer...

INTRODUCCIÓN: Las alteraciones reproductivas de causa masculina relacionadas con el estrés oxidativo son cada día más estudiadas y dan cuenta de causas de infertilidad diagnosticada como idiopáticas. El objetivo del presente trabajo fue evaluar el efecto del zumo de sandía sobre los parámetros sem...

Concentración de bupivacaína y preservación de fuerza de cuádriceps en bloqueo femoral para artroplastía total de rodilla

Rev. chil. anest; 49 (1), 2020
INTRODUCTION: The commonly used concentrations of local anesthetics (LA) for femoral nerve block (FNB) cause a significant decrease in the quadriceps strength (QS), limiting physiotherapy and determining a risk factor for patient’s falls. The use of more dilute solutions could determine the preservatio...

Efecto analgésico del bloqueo PENG (grupo de nervios pericapsulares) en pacientes con fractura de cadera

Rev. chil. anest; 49 (1), 2020
Ultrasound regional blockade emerged that blocks the branches of the femoral nerve, obturator and accessory obturator that innervate the anterior hip capsule, the PENG block (group of pericapsular nerves), which by its Recent description does not have enough evidence in medical practice. To verify the an...

Sensibilidad aumentada a lidocaína: estudio genético de un caso
Increased sensitivity to lidocaine: Genetic study of a case

Rev. chil. anest; 49 (1), 2020
Systemic toxicity by local anesthetics (LAs) is a severe and feared complication in anesthetic practice that generally results from the administration of an inappropriately high dose of LAs or an injection at an inappropriate place, either intravascular or a site with high absorption[1]. However, it is k...

In vitro Studies of Antitumor Activity of Vanadium Complexes with Orotic and Glutamic Acids
