Sirt1 mediates improvement in cognitive defects induced by focal cerebral ischemia following hyperbaric oxygen preconditioning in rats.
Hyperbaric oxygen preconditioning (HBO-PC) has been proposed as a safe and practical approach for neuroprotection in ischemic stroke. However, it is not known whether HPO-PC can improve cognitive deficits induced by cerebral ischemia, and the mechanistic basis for any beneficial effects remains unclear. We addressed this in the present study using rats subjected to middle cerebral artery occlusion (MCAO) as an ischemic stroke model following HBO-PC. Cognitive function and expression of phosphorylated neurofilament heavy polypeptide (pNF-H) and doublecortin (DCX) in the hippocampus were evaluated 14 days after reperfusion
Venous air embolism: ultrasonographic diagnosis and treatment with hyperbaric oxygen therapy.
Abstract: A man with neuromuscular respiratory failure requiring intubation and ventilation suffered a venous air embolism during inadvertent administration of 5 ml of air. Ultrasound (US) imaging confirmed an air embolus in the left subclavian vein, which was only...
Reactive Oxygen Species and NOX Enzymes Are Emerging as Key Players in Cutaneous Wound Repair.
Abstract: Our understanding of the role of oxygen in cell physiology has evolved from its long-recognized importance as an essential factor in oxidative metabolism to its recognition as an important player in cell signaling. With regard to the latter, oxygen is needed...
