Identification of ultrastructural and functional damages in sperm from six-banded armadillos (Euphractus sexcinctus) due to cryopreservation
Pesqui. vet. bras; 36 (8), 2016
The aim of the study was to cryopreserve the semen of six-banded armadillos (Euphractus sexcinctus) in Tris-yolk and glycerol diluent, and to determine the damage caused by the freezing-thawing process, using fluorescent markers and ultrastructural analysis. Semen samples (n=11) collected from 4 adult si...
The advances and new technologies for the study of mitochondrial diseases
Einstein (Säo Paulo); 14 (2), 2016
ABSTRACT Genetic mitochondrial disorders are responsible for the most common inborn errors of metabolism, caused by mutations in either nuclear genes or in mitochondrial DNA. This article presents the prokaryotic origin of the organelle and the relation between nuclear and mitochondrial genomes, as well ...

Effect of hyperbaric oxygenation on mitochondrial function of neuronal cells in the cortex of neonatal rats after hypoxic-ischemic brain damage
Braz. j. med. biol. res; 49 (5), 2016
The timing and mechanisms of protection by hyperbaric oxygenation (HBO) in hypoxic-ischemic brain damage (HIBD) have only been partially elucidated. We monitored the effect of HBO on the mitochondrial function of neuronal cells in the cerebral cortex of neonatal rats after HIBD. Neonatal Sprague-Dawley r...

Fruits and barks extracts of Zanthozyllum heitzii a spice from Cameroon induce mitochondrial dependent apoptosis and Go/G1 phase arrest in human leukemia HL-60 cells
Biol. Res; 47 (), 2014
BACKGROUND: Zanthoxylum heitzii is a spice used to prepare several dishes and to treat tumors, syphilis, malaria, cardiac palpitations, urogenital infections in the west region of Cameroon, but the antitumor mechanisms and chemical composition are not yet investigated. This study was aimed to determine t...

Thyroid hormones, UCPs and termogenesis
Arq. bras. endocrinol. metab; 44 (4), 2000
Calor é um subproduto da transformação de energia, em suas diversas formas, durante a sÃntese e a utilização do ATP. Nos animais homeotérmicos, o calor derivado das funções biológicas - estando o organismo em repouso e à temperatura ambiente - é utilizado para manter o organismo próximo a 37...
