Normobaric oxygen (NBO) and hyperbaric oxygen (HBO) are emerging as a possible co-treatment of acute ischemic stroke. Both have been shown to reduce infarct volume, to improve neurologic outcome, to promote endogenous tissue plasminogen activator-induced thrombolysis and cerebral blood flow, and to improve tissue oxygenation through oxygen diffusion in the ischemic areas, thereby questioning th...
objective: the discovery and development of natural products with potent antioxidant properties has been one of the most interesting and promising approaches in the search for treatment of cns injuries. the most significant consequence of the oxidative stress is thought to be the dna modifications, which can become permanent via the formation of mutations and other types of genomic instability ...
Therapeutic targeting of the tumor vasculature that destroys preexisting blood vessels of the tumor and antiangiogenesis therapy capitalize on the requirement of tumor cells on an intact vascular supply for oxygen and nutrients for growth, expansion and metastasis to the distal organs. Whereas these classes of agents show promise in delaying tumor progression, they also create glucose and oxyge...

BACKGROUND To explore the theoretical basis for protecting the brain from ischemic stroke with tetramethylpyrazine, we studied whether and how tetramethylpyrazine could protect neurons against the oxygen-glucose deprivation (OGD)-induced death and whether transient receptor potential cation channel, subfamily C, member 6 (TRPC6) was involved. MATERIAL AND METHODS Primary rat cortical neurons we...
BACKGROUND It has been demonstrated that cerebral ischemia induces astrocyte reactivity, and subsequent glial scar formation inhibits axonal regeneration during the recovery phase. Investigating the mechanism of glial scar formation will facilitate the development of strategies to improve axonal regeneration. However, an in vitro model of ischemia-induced glial scar has not yet been systematica...
BACKGROUND The present study aims to investigate the effect of noscapine (0.5-2.5 μM), an alkaloid from the opium poppy, on primary murine fetal cortical neurons exposed to oxygen-glucose deprivation (OGD), an in vitro model of ischemia. METHODS Cells were transferred to glucose-free DMEM and were exposed to hypoxia in a small anaerobic chamber. Cell viability and nitric oxide production were...
Due to poor tumour-associated vasculature, tumour cells are subjected to a fluctuating microenvironment with periods of limited oxygen and glucose availability. Adaptive mechanisms to adverse microenvironments are important for tumour cell survival. The cyclooxygenase (COX)-2/prostaglandin E(2) (PGE(2)) pathway has key roles in colorectal tumorigenesis. Although glucose is important as an energ...
Introduction: The Serum/Glucose deprivation -induced cell death in cultured PC12 cells represents a useful in vitro model for the study of brain ischemia and neurodegenerative disorders. Nigella sativa L. has been known as a source of antioxidants. To elucidate the neuroprotective actions of N. sativa extract in vitro, we studied the effect of N. sativa extract on cultured PC12 cells under s...
