Stroke-prone spontaneously hypertensive rats (SHRSP/Izm; SHRSP) develop severe hypertension and die of cerebral stroke. However, the genetic mechanisms underlying their stroke susceptibility have not been clarified yet. In this study, we used astrocytes from the newborn brain cortex of spontaneously
Hydrogen sulfide is believed to be a signalling molecule in the central nervous system. It is known to increase rapidly following an ischemic insult in experimental stroke. Is it protective or deleterious? This review surveys the relevant information available in the literature. It appears that
Stroke is a kind of acute cerebrovascular disease characterized by the focal lack of neurological function, including ischemic stroke and hemorrhagic stroke. As society ages rapidly, stroke has become the second leading cause of disability and death, and also become the main threat to human health
Cysteine is known to cause neuronal cell death and has been reported to be elevated in brain ischemia, but it has not been studied in clinical stroke. In this study, we correlated plasma levels of cyst(e)ine with long-term clinical outcome at 3 months in acute stroke. Patients were classified into 3
Hydrogen sulfide (H2S) has been identified as a vasodilatory, neuromodulatory, and anti-inflammatory gasotransmitter with antioxidant properties. Studies focused in cardiac tissue suggest H2S functions as a protective agent; however in the central nervous system (CNS) the
Hydrogen sulfide (H2S) is now known as an important neuromodulator in the central nervous system. The aim of the current study was to investigate whether exogenous H2S gas can attenuate brain edema induced by experimental stroke and to clarify the potential mechanisms. Rats underwent 2-h middle
Hydrogen sulfide is believed to be a signalling molecule in the central nervous system. It is known to increase rapidly following an ischemic insult in experimental stroke. Is it protective or deleterious? This review surveys the relevant information available in the literature. It appears that
Tissue plasminogen activator (tPA), the only approved drug for the treatment of ischemic stroke, increases the risk of cerebral hemorrhage. Here, we investigated whether the newly identified gaso-transmitter hydrogen sulfide (H2S), when used in combination with tPA, reduced the hemorrhagic
Nitric oxide (NO) and hydrogen sulfide (H2S) are the key gasotransmitters with an imperious role in the maintenance of cerebrovascular homeostasis. A decline in their levels contributes to endothelial dysfunction that portends ischemic stroke (IS) or cerebral ischemia/reperfusion (CI/R).
NOSH-NBP, a novel nitric oxide (NO) and hydrogen sulfide (H2S)-releasing hybrid, protects brain from ischemic stroke. This study mainly aimed to investigate the therapeutic effect of NOSH-NBP on ischemic stroke and the underlying mechanisms. In vivo, transient middle cerebral artery occlusion
In the present study, a series of hydrogen sulfide (H2S) releasing derivatives (8a–g and 9a–f) of 3-n-butylphthalide (NBP) were designed, synthesized and biologically evaluated. The most promising compound 8e significantly inhibited the adenosine diphosphate (ADP) and arachidonic acid (AA)-induced
OBJECTIVE
Hydrogen sulfide (H2S) plays multiple roles in the function of the central nervous system in physiological and pathological conditions, such as cerebral ischemia. Recent studies have reported controversial results about the role of H2S in cerebral ischemia. The aim of this study was to
3-Mercaptopyruvate sulfurtransferase (3MST) is an important enzyme for the synthesis of hydrogen sulfide (H2S) in the brain. We present here data that indicate an exclusively localization of 3MST in astrocytes. Regional distribution of 3MST activities is even and unremarkable. Following permanent
Stroke is a cerebrovascular disease displaying high mortality and morbidity. Despite extensive efforts, only very few therapies are available for stroke patients as yet. Hydrogen sulfide (H2S) is thought to be a signalling molecule that is endogenously produced and plays functional roles
In aged humans, stroke is a major cause of disability for which no neuroprotective measures are available. In animal studies of focal ischemia, short-term hypothermia often reduces infarct size. Nevertheless, efficient neuroprotection requires long-term, regulated lowering of whole body temperature.
