As ischemic stroke is associated with an excessive release of glutamate into the neuronal extracellular space, a decrease in blood glutamate levels could provide a mechanism to remove it from the brain tissue, by increasing the brain-blood gradient. In this regard, the ability of glutamate oxaloacetate transaminase (GOT) to metabolize glutamate in blood(More)
Sevoflurane is an anesthetic agent which also participates in protective mechanisms in sepsis, likely due to anti-inflammatory properties. A key tissue in sepsis is the endothelium, which expresses TLR2 and TLR4 receptors, known regulators of inflammatory mechanisms and potential therapeutic targets for this pathology. In this context, we explored the(More)
OBJECTIVES The increase in circulating endothelial progenitor cells (EPCs) is associated with a better outcome in patients with acute ischemic stroke. CDP-choline (citicoline) increases brain plasticity after experimental stroke. Therefore, we study if citicoline treatment could increase the EPC concentration after ischemic stroke. METHODS Forty-eight(More)
OBJECTIVE An increase in the circulating concentration of endothelial progenitor cells (EPCs) is associated with a better outcome in patients with acute ischemic stroke. Likewise, EPCs are heterogeneous cells, with functional differences and different protein expressions. Our objective was to compare protein expressions of EPCs from ischemic stroke(More)
PURPOSE To identify proteins differentially expressed between the tear film of keratoconus (KC) patients and control subjects using two dimensional electrophoresis (2-DE) and mass spectrometry-based techniques. METHODS Twenty two patients (44 eyes) diagnosed with bilateral KC and 22 control subjects (44 eyes) were studied in a prospective case-control(More)
BACKGROUND Neuroserpin has shown neuroprotective effects in animal models of cerebral ischemia and has been associated with functional outcome after ischemic stroke. Our aim was to study whether neuroserpin serum levels could be associated to biomarkers of excitotoxicity, inflammation and blood brain barrier disruption. METHODS We prospectively included(More)
BACKGROUND Stroke subtype diagnosis leads to specific therapies to reduce recurrences. Because nearly one third of patients remain with unknown etiology after a complete screening workup, we aim to investigate whether molecular markers of myocardial damage were associated with cardioembolic stroke and if they were useful to reclassify strokes of(More)
Besides its role as a thrombolytic agent, tissue plasminogen activator (tPA) triggers harmful effects in the brain parenchyma after stroke, such as inflammation, excitotoxicity and basal lamina degradation. Neuroserpin, a natural inhibitor of tPA, has shown neuroprotective effects in animal models of brain infarct. However, the molecular mechanisms of(More)
Many patients that survive stroke have to face serious functional disabilities for the rest of their lives, which is a personal drama for themselves and their relatives, and an elevated charge for society. Thus, functional recovery after stroke must be a key aspect of the development of new therapeutic approaches. This is the second of a series of two works(More)
BACKGROUND Ventilatory strategy and specifically positive end-expiratory pressure (PEEP) can modulate the inflammatory response and pulmonary-to-systemic translocation of lipopolysaccharide (LPS). Both inflammation and ventilatory pattern may modify brain activation, possibly worsening the patient's outcome and resulting in cognitive sequelae. METHODS We(More)
