BACKGROUND Amino acids have been reported to act as modulators of various regulatory processes and to provide new therapeutic applications for either the prevention or treatment of metabolic disorders. The purpose of the present study is to investigate the effects of single oral dose administration

Previous studies have suggested that substance P (SP) plays a critical role in the development of brain oedema and functional deficits following traumatic brain injury and that SP receptor antagonism may improve outcome. No studies have described such a role in ischemic stroke. The present study

We have recently reported on the efficacy of an NK1 tachykinin receptor antagonist in improving outcome following stroke, including reduced blood-brain barrier (BBB) disruption, reduced cerebral edema and improved functional outcome. The clinically approved stroke treatment, tissue plasminogen

We aimed to determine the serum concentrations of altered compounds to understand the changes in metabolism and pathophysiology that occur prior to thrombotic stroke. In this prospective cohort study, high-resolution metabolomics (HRM) was employed to analyze serum samples obtained from patients at

I have discussed 10 "new" diseases. Some produce heart disease, some produce strokes, and some may produce both heart disease and stroke. It is of great interest to me that some of them are due not to nature's ravages but to the ingestion of agents such as toxic oil, L-tryptophan, ergot, adriamycin,

Matrix metalloproteinases (MMPs) have been implicated in the pathophysiology of ischemic stroke. In particular, the gelatinases MMP-2 and MMP-9 contribute to disruption of the blood-brain barrier and hemorrhagic transformation following ischemic injury. In addition to extracellular matrix

Neonatal swimming behavior was studied after a single subcutaneous injection of L-dopa methyl ester (50 mg/kg; 200 mg/kg) apomorphine (0.1 mg/kg; 1.0 mg/kg), DL-amphetamine (0.5 mg/kg; 10 mg/kg), haloperidol (0.5 mg/kg; 1.0 mg/kg), L-tryptophan (50 mg/kg; 100 mg/kg), methysergide (1.0 mg/kg; 5.0

Excitatory amino acid (EAA)-mediated synaptic transmission is the most prevalent excitatory system within the mammalian brain. Activation of EAA receptors has been postulated to contribute to neuronal cell death in stroke, epilepsy, hypoglycemia, and Huntington's disease. Kynurenic acid is an

BACKGROUND Raised intracranial pressure (ICP) following SAH predicts poor outcome and is due to hemorrhage volume and possibly, brain edema, hydrocephalus and increased volume of circulating intracranial blood. Interventions that reduce edema may therefore reduce ICP and improve outcome. The
