background : foreign body aspiration is a common medical emergency among children that can lead to lethal complications especially in neglected or misdiagnosed cases. case report: this article is a report of a 15-month-old child who aspirated food materials and after chocking crisis, she presented with unspecific respiratory symptoms and treated for respiratory tract infections. after five days...

background: nepeta dschuparensis bornm (np) is used as a medicinal herb in iran. in traditional medicine, this herb is extensively employed for curing ailments such as cardiovascular diseases. np has antioxidant and anti-inflammatory properties. this project examined the effects of the np extract on cyclooxygenase-2 (cox-2) and interleukin-1β (il-1β) protein levels and its efficacy in neuroprot...

objective: transplantation of mesenchymal stem cells (mscs) can promote functional recovery of the brain after hypoxic-ischemic brain damage (hibd). however, the mechanism regulating msc migration to a hypoxic-ischemic lesion is poorly understood. interaction between stromal cell-derived factor-1α (sdf-1α) and its cognate receptor cxc chemokine receptor 4 (cxcr4) is crucial for homing and migra...

background: brain hypoxia-ischemia is a human neonatal injury that is considered a candidate for stem cell therapy. methods: the possible therapeutic potential of human umbilical cord blood (hucb) stem cells was evaluated in 14-day-old rats subjected to the right common carotid occlusion, a model of neonatal brain hypoxia-ischemia. seven days after hypoxia-ischemia, rats received either saline ...

In this article, we are reporting a case of acute stroke that occurred in young patient with iron deficiency anaemia (IDA). There only few cases where the association between IDA and has been established. The possible mechanisms behind relation anaemic hypoxia-induced to brain, hypercoagulable state secondary thrombocytosis IDA. patient, all causes were ruled out except Iron which came be reaso...

Objective(s): Impairment of nerve cells of brain induced by hypoxia results in energy-deprivation and dysfunction, which accompanies with neurons apoptosis. Improving function of nerve cells is important for treating cerebral anoxia. This study aimed to investigate the role of Quercetin (Quer) in hypoxia-induced injury of pheochromocytoma (PC-12) cells. Materials and Methods: PC-12 cells were c...

Hypoxia-sensitive peripheral carotid chemoreceptors, which regulate sympathetic outflow from the brain stem, are promising antihypertensive treatment targets. However, central nervous pathways integrating human chemoreflexes poorly understood. We combined high-resolution functional magnetic resonance imaging with physiological profiling to elucidate hypothalamic and medullary responses acute hy...

Objective(s): The aim of this study is to explore the potential neuroprotective effects of Ginkgolide B (GB), a main terpene lactone and active component in Ginkgo biloba, in hypoxia-induced neuronal damage, and to further investigate its possible mechanisms.Materials and Methods: 54 Sprague-Dawley rats were randomly divided into three groups: the untreated control group (n=18); the hypoxia gro...
