Liraglutide restores late cardioprotective effects of remote preconditioning in diabetic rats via activation of hydrogen sulfide and nuclear factor erythroid 2-related factor 2 signaling pathway

Acta cir. bras; 36 (2), 2021
ABSTRACT Purpose The present study explored the influence of liraglutide on remote preconditioning-mediated cardioprotection in diabetes mellitus along with the role of nuclear factor erythroid 2-related factor 2 (Nrf2), hypoxia inducible factor (HIF-1α) and hydrogen sulfide (H2S). Methods Strepto...

Octreotide-mediated neurofunctional recovery in rats following traumatic brain injury. Role of H2S, Nrf2 and TNF-α

Acta cir. bras; 36 (12), 2021
ABSTRACT Purpose: To explore the role and mechanisms of octreotide in neurofunctional recovery in the traumatic brain injury (TBI) model. Methods: Rats were subjected to midline incision followed by TBI in the prefrontal cortex region. After 72 hours, the behavioural and neurological deficits tests wer...

Hydrogen sulfide protects H9c2 cardiomyoblasts against H2O2-induced apoptosis

Braz. j. med. biol. res; 52 (4), 2019
Reactive oxygen species (ROS) are highly reactive chemical species that may cause irreversible tissue damage, and play a critical role in cardiovascular diseases. Hydrogen sulfide (H2S) is a gasotransmitter that acts as a ROS scavenger with cardio-protective effects. In this study, we investigated the cy...

Involvement of K+ATP and Ca2+ channels in hydrogen sulfide-suppressed ageing of porcine oocytes

Biol. Res; 51 (), 2018
BACKGROUND: Hydrogen sulfide has been shown to improve the quality of oocytes destined for in vitro fertilization. Although hydrogen sulfide is capable of modulating ion channel activity in somatic cells, the role of hydrogen sulfide in gametes and embryos remains unknown. Our observations confirmed the ...
