OBJECTIVE Stroke-like episodes signal progression and significant disability in the mitochondrial encephalomyopathy lactic acidosis and stroke-like episodes syndrome. Arginine is widely used as a treatment for stroke-like episode, although there is little evidence for this intervention. We discuss

BACKGROUND Adenosine triphosphate-sensitive potassium (KATP) channels in brain are involved in neuroprotective mechanisms. Pharmacologic activation of these channels is seen as beneficial, but clinical exploitation by using classic K channel openers is hampered by their inability to cross the

CONCLUSIONS Glutamate serves multi-faceted (patho)physiological functions in the central nervous system as the most abundant excitatory neurotransmitter and under pathological conditions as a potent neurotoxin. Regarding the latter, elevated extracellular glutamate is known to play a central role in

OBJECTIVE Methamphetamine is a powerful addictive, which has been associated with ischemic stroke and brain hemorrhage in humans. Whether and how methamphetamine influences the expression of tight junctions and adenosine triphosphate-binding cassette transporters, which have previously been shown to

The central nervous system is especially vulnerable to hyperthermia-induced dysfunction, yet the mechanism for this susceptibility is poorly understood. High levels of adenosine triphosphate are necessary to maintain normal re-uptake of glutamate and aspartate, the major excitatory amino acids, by

To examine the cardiovascular response to prostaglandin E1 infusion, we observed hemodynamic changes including left ventricular diameter (an ultrasonic crystal pair) during PGE(1)-induced hypotension in anesthetized open-chest dogs. Left ventricular contractility was assessed primarily by measuring

In the present study, we used a comprehensive cellular toxicity (CeeTox) analysis panel to determine the toxicity profile for CNB-001 [4-((1E)-2-(5-(4-hydroxy-3-methoxystyryl-)-1-phenyl-1H-pyrazoyl-3-yl)vinyl)-2-methoxy-phenol)], which is a hybrid molecule created by combining cyclohexyl bisphenol

Current research suggests that ischemia induces a massive shift of calcium from the extracellular fluid to the intracellular space. This is associated with a precipitous decrease in the concentration of adenosine triphosphate, the energy source required to drive the ion pumps of the calcium channels

We used transmission electron microscopy to count the organelles (dense bodies, alpha granules, and mitochondria) contained within platelets from 11 acute ischemic stroke patients and 12 healthy controls. We randomly selected for evaluation 25 platelet profiles in ultrathin sections cut from three

The adenosine triphosphate-binding cassette efflux transporter ABCG2, which is located in the blood-brain barrier limits the entry of endogenous compounds and xenobiotics into the brain, and its expression and activity are regulated by estrogen. This study was aimed to define the role of ABCG2 in

We encountered a 10-year-old girl with fluctuating sensorineural hearing loss, episodic headache, and white matter stroke. Strenuous exercise, febrile illness, and general anesthesia all temporarily worsened hearing. Audiologic findings were asymmetric: left-sided retrocochlear dysfunction

Mucus propelling cilia are excitable by many stimulants, and have been shown to increase their beating frequency up to threefold, by physiological extracellular stimulants, such as adenosine-triphosphate, acetylcholine, and others. This is thought to represent the evolutionary adaptation of

This study tests the hypotheses that postischemic adenosine triphosphate levels are unreliable predictors of functional recovery, myocardial adenosine triphosphate concentration of less than 2 mumol/gm does not indicate irreversible damage, mitochondrial adenosine triphosphate generating capacity

OBJECTIVE Eicosapentaenoic acid (EPA) can ameliorate certain liver lesions involved in non-alcoholic steatohepatitis (NASH). A previous study has found that stroke-prone spontaneously hypertensive 5/Dmcr (SHRSP5/Dmcr) rats fed a high fat-cholesterol (HFC) diet developed fibrotic steatohepatitis with
