Sympathetic neurons synthesize, transport, and release tissue-type plasminogen activators (t-PAs) and urinary-type plasminogen activators (u-PAs). We reported that t-PA enhances sympathetic neurotransmission and exacerbates reperfusion arrhythmias. We have now assessed the role of u-PA and plasminogen. Neurogenic contractile responses to electrical field stimulation (EFS) were determined in vas...

background: pectin is composed of complex polysaccharides that can inhibit cancer metastasis and proliferation with no evidence of toxicity. in the present study, the apoptotic and necrotic effects of pectic acid (pa) on the rat pituitary gh3/b6 tumor cells has been investigated. methods: gh3/b6 cells were cultured in the ham’s f12 medium enriched with 15% horse serum and 2.5% fetal bovine seru...

Plasminogen activator (PA) activity, in particular urokinase (u-PA), has been shown to be markedly increased in adenocarcinomas of the colon. Adenomatous polyps were found to be intermediate in their PA activity to normal mucosa and adenocarcinomas. In the present study we evaluated the PA profile in relation to malignancy parameters of the adenomas. Forty-eight adenomatous polyps, obtained by ...

objective: to evaluate the efficacy and safety of intravenous and catheter directed thrombolysis by recombinant tissue plasminogen activator (alteplase) in the patients with non-traumatic acute limb ischemia (ali). methods: this was a randomized clinical trial being performed between 2009 and 2011 in mashhad university of medical sciences. we included those patients who were<75 years, with symp...

Recombinant tissue plasminogen activator (rt-PA) is one of the most important thrombolytic agents for treating cardiovascular obstructions such as stroke. Glycoprotein rt-PA is a serine protease, consisting of 527 amino acids of which 35 are cysteine residues. A variety of recombinant protein expression systems have been developed for heterologous gene expression in prokaryotic and eukaryotic h...

The effect of Escherichia coli strains isolated from blood and cerebrospinal fluid of septic infants on plasminogen activation was studied. These strains typically carry a filamentous surface protein, S fimbria, that has formerly been shown to bind to endothelial cells and interact with plasminogen. The. bacteria effectively promoted plasminogen activation by tissue plasminogen activator (t-PA)...
