The t-PA/PAI-1 complex is a good indicator of the release of fibrinolysis activators and inhibitors from the vascular wall, but its clinical significance in chronic ischemic heart disease is unclear. The plasma levels of tissue-type plasminogen activator (t-PA), plasminogen activator inhibitor-1 (PAI-1), and the t-PA/PAI-1 complex (including various coagulation factors) were assayed in 72 patie...

To delineate interactions of infused tissue-type plasminogen activator (t-PA) with inhibitors in plasma and their impact on fibrinolytic activity, serial plasma samples from patients with acute myocardial infarction and from normal rabbits given infusions of t-PA were assayed for t-PA antigen, activity of "fast acting" plasminogen activator inhibitor (PAI-1), and the presence and nature of t-PA...

pinch analysis (pa) is used as a powerful tool for targeting and synthesis of heat and mass exchange networks. pa for solving includes extended and complex operation although having a simple concept. according to this matter, need for creating a pa software is clear hence famous an american and european cooperation introduce extensive and powerful software by applying advanced programming langu...

Background & Aims: Age-related macular degeneration (ARMD) is one of the common retina disorders that can lead to loss of vision by increase in age. In this study, the efficacy of a non-invasive ultrasound technique for the evaluation of alastic properties of eye in the diagnosis of ARMD has been evaluated. Methods: For estimation of the elastic modulus of eye, spatial loading system designed a...

Heparin stimulates the activity of tissue plasminogen activator (t-PA) and binds to t-PA. To study this interaction, a complex between t-PA and N-acetylated heparin was formed and then linked to Sepharose. This procedure selectively links the t-PA to the column because the acetylated heparin has no free amino groups. The procedure also protects the heparin-binding site(s) on the enzyme during c...

The efficacy of recombinant vampire bat salivary plasminogen activator (bat-PA) as a thrombolytic agent was compared with that of human tissue-type plasminogen activator (t-PA) in a canine model of arterial thrombosis. An occlusive thrombus was formed in the femoral artery by insertion of a thrombogenic copper coil; femoral arterial blood flow was monitored with a Doppler flow meter. Bat-PA and...

In this investigation, rheological properties of three different polymer-modified bitumen compounds containing recycled polyethylene terephthalate (R-PET), crumb rubber (CR) and poly (styrene-butadiene-styrene) (SBS) are evaluated and compared. The modified samples were tested by a dynamic shear rheometer (DSR) where complex modulus (G*), phase angle (δ) and rutting resistance (G*/Sinδ) of spec...
