Remote ischemic conditioning enhances heart and brain antioxidant defense

Abstract Background Ischemia-reperfusion injury contributes to morbidity after revascularization procedures. Along with early reperfusion, tissue conditioning by alternating intervals of brief ischemia-reperfusion episodes is considered the best approach to limit tissue damage. Remote ischemic condition...

Medida computadorizada da evolução da área cicatricial tratada com ultrassom terapêutico e citrato de sildenafila

Objetivou-se comparar a evolução da cicatrização de feridas cirúrgicas com cinco protocolos de tratamento através de análise planimétrica. Grupos de 12 ratos Wistar, foram alocados em cinco estudos experimentais: A- controle negativo; B- ferida cirúrgica, tratada com ultrassom terapêutico (UST)...

Efecto de la n-acetilcisteina inhalada en el desarrollo de fibrosis pulmonar de ratas intoxicadas con paraquat
Effect of n-acetylcisteine inhaled in the development of pulmonary fibrosis of intoxicated rats with paraquat

Rev. Inst. Nac. Hig; 50 (1-2), 2019
El Paraquat (PQ) es un herbicida de contacto bipiridilico ampliamente utilizado en agricultura. La intoxicación en humanos por este agente ocasiona fibrosis pulmonar. Evaluamos los cambios histológicos pulmonares de ratas intoxicadas con PQ y tratadas con N-aceticisteina (NAC) administrada vía inhalat...

Effects of intra-dentate gyrus microinjection of myokine irisin on long-term potentiation in male rats

Arq. neuropsiquiatr; 77 (12), 2019
ABSTRACT Induction of long-term potentiation (LTP) increases the storage capacity of synapses in the hippocampal dentate gyrus (DG). Irisin is a myokine generated from FNDC5 (a gene precursor) during exercise. Although intra-cornu ammonis 1 administration of irisin fortifies LTP in mice with Alzheimer's ...

Evaluación de la Administración Infiltrativa de vitamina E y alendronato en la Reparación de Alvéolos Post Exodoncia de Ratas

RESUMEN: Los bisfosfonatos (BP) disminuyen la resorción ósea al frenar la actividad de los osteoclastos. La vitamina E es antioxidante y su efecto positivo en el hueso sería mediante la prevención del estrés oxidativo. Se estudió la administración infiltrativa de Alendronato y Vitamina E para dete...

Analysis of Estrogen Effects on Eruption of Rat Molars

ABSTRACT: Tooth eruption requires resorption of the alveolar bone interposed between the tooth germ and the oral mucosa (coronal bone). The cells responsible for bone resorption are the osteoclasts and their activity can be reduced or inactivated by estrogen hormone. We aimed to investigate the effects o...

Cafeteria diet in breastfeeding dams promotes anxiolytic effects, accumulation of adipose tissue, and impacts offspring development

Rev. chil. nutr; 46 (6), 2019
The aim of this study was to evaluate the nutritional and behavioral effects of a cafeteria diet in dams during the breastfeeding period and in their offspring from weaning until early adulthood (70 days old). Pregnant Wistar rats were fed a chow diet until delivery. Postnatally (D0), litters were culled...

Influence of green tea extract with different concentrations of epigallocatechin gallate on calvaria bone repair of ovariectomized rats

Int. j. morphol; 37 (4), 2019
Impairing osteoporosis progression is a challenge, and recently the role of antioxidants has been associated to bone metabolism. Green tea extract is rich in catechins, especially epigallocatechin gallate (EGCG), which may help control osteoporosis damage in bone tissue. This investigation evaluated the ...
