Damped response theory is applied to the calculation of two-photon absorption (TPA) spectra, which are determined directly, at each frequency, from a modified damped cubic response function. The TPA spectrum may therefore be evaluated for selected frequency ranges, making the damped TPA approach attractive for calculations on large molecules with a high density of states, where the calculation ...

This document describes the test estimate preparation technique known as test point analysis (TPA). TPA can be used to objectively prepare an estimate for a system test or acceptance test. TPA covers only so-called black-box testing; an estimate for the test activities, which precede black-box testing (i.e. white-box testing), will already have been included in the estimate produced by function...

The aim of the study is to assess the diagnostic accuracy of some fibrinolytic parameters in the differential diagnosis between patients with unstable angina (UA) and musculoskeletal disorders (MSD). Methods. This cross-sectional study included 119 patients with chest pain (CP) and provisional diagnosis “UA”. After a full set of diagnostic procedures, authors formed 4 groups: patients with isc...

Tetraprenylacetone (TPA: teprenon, geranylgeranylacetone) is a novel anti-ulcer agent developed in Japan. The aim of this study was to test whether TPA has the ability to promote the healing process of rat gastric mucosal injury induced by absolute ethanol (ET). Fasted rats received orally 5 ml/kg of absolute ET. Sixty minutes later, TPA (200 mg/kg) or saline (control) was administered intragas...

Tissue Plasminogen Activator And Plasminogen Activator Inhibitor-1 Gene Expression in Muscle After Maximal Acute Aerobic Exercise. JEPonline 2010;13(6):35-44. Animal studies suggest plasminogen activation in skeletal muscle is necessary for muscle repair. However, plasminogen activators have been studied little in humans. T...

BACKGROUND AND PURPOSE Hemorrhagic conversion after tissue plasminogen activator (tPA) stroke therapy has been linked with elevations in matrix metalloproteinase-9 (MMP-9) at the neurovascular interface. Here, we test the idea that statins may directly ameliorate tPA-induced MMP-9 dysregulation. METHODS Recombinant human tPA (5 microg/mL) was added to primary rat cortical astrocytes. Zymograp...

BACKGROUND AND PURPOSE Tissue plasminogen activator (tPA) is an effective treatment for stroke, but its utility is limited by fear of cerebral hemorrhage. Tenecteplase (TNK), a genetically modified form of wild-type tPA, exhibits a longer biological half-life and greater fibrin specificity, features that could lead to fewer cerebral hemorrhages than wild-type tPA in stroke patients. METHODS W...
