BACKGROUND AND PURPOSE In ischemic stroke, the site of arterial obstruction has been shown to influence recanalization and clinical outcomes. However, this has not been studied in randomized controlled trials, nor has the impact of arterial obstruction site on reperfusion and infarct growth been assessed. We studied the influence of site and degree of arterial obstruction patients enrolled in t...

Seven patients were treated with recombinant human tissue plasminogen activator (tPA) for severe hepatic venocclusive disease (VOD) that developed after bone marrow transplantation for hematologic malignancy. Recombinant human tPA (10 mg/d x 2 days) and heparin (1,000 U bolus followed by continuous intravenous infusion of 150 U/kg/d x 10 days) were begun a median of 9 days (range, 4 to 18 days)...

BACKGROUND Thrombolytic therapy is the only approved treatment for acute cerebral ischemia. The hemorrhagictransformation is the greatest complication of this treatment, which may occur after recanalization of occludedartery. The aim of this study was to determine factors associated with clinical improvement and worseningin patients with acute ischemic stroke treated with intravenous thrombolys...

BACKGROUND AND PURPOSE Therapeutic effects of early insulin glycemic control for poststroke hyperglycemia in combination with tissue-type plasminogen activator (tPA) thrombolytic therapy have not yet been studied but are of great clinical interest. In this study, we tested the effects of insulin plus tPA combination in a model of focal embolic stroke in Type I diabetic rats. METHODS Streptozo...

Apo E, and its respective isoforms, have been linked to outcome and survival in cerebral vascular and cardiovascular diseases. The effectiveness of intravenous tPA in patients with acute ischemic stroke appears to be enhanced in patients who have an Apo E2 phenotype. The ability of Apo E isoproteins (endogenous Apo E isoproteins or exogenous Apo E isoproteins) to modulate tPA-induced clot lysis...

We present a new approach to investigate how the photodynamics of an octahedral ruthenium(II) complex activated through two-photon absorption (TPA) differ from the equivalent complex activated through one-photon absorption (OPA). We photoactivated a Ru(II) polypyridyl complex containing bioactive monodentate ligands in the photodynamic therapy window (620-1000 nm) by using TPA and used transien...

Tissue plasminogen activator (tPA) is the only approved thrombolytic therapy for acute ischemic stroke, yet many patients do not recanalize. Enhancing thrombolytic efficacy of tPA is a major focus of stroke research. Traditionally, a "rat dose" of 10 mg/kg has been used in rodent models. Recent studies suggested that the clinical "human" dose (0.9 mg/kg) may better mimic clinical recanalization...

Progression of human prostate cancer to a malignancy that is refractory to androgen-ablation therapy renders the disease resistant to available treatment options and accounts for the high prostate cancer mortality rate. Epidermal growth factor receptor (EGFR) expression in human prostate cancer specimens increases with disease progression to androgen-refractory prostate cancer, and experimental...

BACKGROUND AND PURPOSE Compare access and outcomes in a tertiary care community hospital (Saint Luke's Neuroscience Institute) and its stroke network to hospitals in 3 national databases. METHODS Retrospective analysis of ischemic stroke patients (2005, 2007, 2010) in Saint Luke's (n=1576), Get With The Guidelines-Stroke (n=423 809), Premier (n=91 598), and Merci Registry (n=966). Study measu...
