Chronic intermittent hypoxia exposure induces memory impairment in growing rats.
The study was aimed to examine the effect of chronic intermittent hypoxia (CIH) on spatial memory of growing rats and to explore the possible underlying mechanisms. Sixty two rats were trained to perform the 8-arm radial maze task and were divided into four groups: 2-week-CIH (2IH) 2-week-control (2C) 4-week-CIH (4IH) and 4-week-control (4C). There were more reference memory errors, working mem...
متن کاملImpact of Magnesium Deficiency on Pancreatic β-Cell Function in Type 2 Diabetic Nigerians
Objective: Pancreatic b-cell dysfunction is described to be present at the diagnosis of type 2 diabetes mellitus (T2DM) and progressively deteriorated with disease duration. However, its progression is variable and potentially influenced by several factors. The Magnesium (Mg) deficiency mediates insulin resistance but reports regarding its role in pancreatic β-cell dysfunction are scarce and co...
متن کاملChronic intermittent hypoxia/reoxygenation facilitate amyloid-β generation in mice.
Previous studies have shown a high prevalence of obstructive sleep apnea (OSA) among patients with Alzheimer's disease (AD). However, it is poorly assessed whether chronic intermittent hypoxia (CIH), which is a characteristic of OSA, affects the pathophysiology of AD. We aimed to investigate the direct effect of intermittent hypoxia (IH) in pathophysiology of AD in vivo and in vitro. In vivo, 1...
متن کاملSympatho-adrenal activation by chronic intermittent hypoxia.
Recurrent apnea with chronic intermittent hypoxia (CIH) is a major clinical problem in adult humans and infants born preterm. Patients with recurrent apnea exhibit heightened sympathetic activity as well as elevated plasma catecholamine levels, and these phenotypes are effectively recapitulated in rodent models of CIH. This article summarizes findings from studies addressing sympathetic activat...
متن کاملProtocatechuic acid ameliorates neurocognitive functions impairment induced by chronic intermittent hypoxia
Chronic intermittent hypoxia (CIH) is a serious consequence of obstructive sleep apnoea (OSA) and has deleterious effects on central neurons and neurocognitive functions. This study examined if protocatechuic acid (PCA) could improve learning and memory functions of rats exposed to CIH conditions and explore potential mechanisms. Neurocognitive functions were evaluated in male SD rats by step-t...
