We have shown that the capacity for local release of tissue-type plasminogen activator (tPA) from the vascular endothelium is impaired in patients with primary hypertension. Because this response is an important protective mechanism against intravascular clotting, we investigated whether this system is also defective in patients with advanced chronic kidney disease and hypertension. Nine nondia...

BACKGROUND AND PURPOSE An ability to predict early reperfusion with IV tPA in patients with acute ischemic stroke and intracranial clots can help clinicians decide if additional intra-arterial therapy is needed or not. We explored the association between novel clot characteristics on baseline CTA and early reperfusion with IV tPA in patients with acute ischemic stroke by using classification an...

The induction of epidermal ornithine decarboxylase (EC 4.1.1.17) (ODC) following topical application of the tumorpromoting agent 12-O-tetradecanoylphorbol-13-acetate (TPA) to mice can be inhibited by topical application of putrescine, the product of the enzyme. The degree of inhibition depended on both the dose and the time of putrescine application; appli cation of 20 jumol of putrescine 2 hr ...

Hyperglycemia and dyslipidemia are two biochemical markers of diabetes mellitus. Increased incidence of cardiovascular disease and impaired fibrinolytic activity have been found in diabetic subjects. Previous studies have demonstrated that low density lipoproteins (LDLs) stimulate the production of plasminogen activator inhibitor-1 (PAI-1) and reduce the generation of tissue plasminogen activat...

Colorectal carcinoma is a leading cause of human mortality due to its high metastatic ability. Because the activation of matrix metalloproteinases (MMP) is a key factor in the metastatic process, agents with the ability to inhibit MMP activity have potential in the treatment of colorectal carcinoma. In the present study, among 36 flavonoids examined, myricetin was found to be the most potent in...

introduction: at present, most recombinant proteins are produced in prokaryotes especially e coli. yeasts and cho also are used as eukaryotic hosts. leishmania tarentolae, a parasite of lizards, a member of trypanosomatidae family is one of the new systems for expression of heterologous proteins. in this system, some of the parasitic protozoa features are used in expression of mammalian protein...

conclusions due to considerable inter- and intra- heterogeneity among studies performed by other centers such as differences in study project, background, and population features, determining a pharmacotherapy model based on safe implementation of treatments in stroke or sits seem advantageous. results age, time of onset, systolic blood pressure, diabetes, stroke severity, co-morbidities and pr...
