Human tissues and cells from pre- and postnatal life were cultivated and studied for plasminogen activator activity. Cultures were obtained from kidney, renal blood vessels, ureter, bladder, lung, and heart. Local activator activity of cells was demonstrated by histochemical techniques. Activator released by cells into the supernatant culture media was assayed by fibrin plate techniques and was...

a new method was used to prepare abs/pa6 blends by in situ polymerization and compatibilization method. in this process, ε-caprolactam monomer was polymerized in presence of abs via activated anionic polymerization to produce pa6. the main ingredients of the reaction mixture included: monomer ()ε-caprolactam), catalyst na-caprolactamate), microactivator hdi)( and macro-activator sma)(. then, in...

BACKGROUND AND PURPOSE From small pilot studies, uncontrolled pretreatment systolic blood pressure >185 mm Hg and diastolic blood pressure >110 mm Hg in patients with acute ischemic stroke were introduced in the National Institute of Neurological Diseases and Stroke rtPA Stroke Study as a contraindication for thrombolysis. We sought to determine if pretreatment blood pressure protocol violation...

background sepsis is one of the most important causes of morbidity and mortality in the intensive care units (icus). it is difficult to accurately differentiate sepsis from similar diseases rapidly. therefore, it becomes critical to identify any biomarker with the ability of differentiation between sepsis and nonsepsis conditions. the urokinase plasminogen activator receptor has been implicated...

echis carinatus (saw-scale viper) is one of the most venomous snakes in asia and some parts of the africa with deadly hemotoxic venom. it has been reported that suramin, an antitrypansomiasis drug, can inhibits the toxic effects of some snake venoms. this study was conducted to evaluate the antagonistic effects of suramin against the venom of the iranian snake echis carinatus. adult albino mice...

Background : Triglyceride examination was carried out in three stages, namely pre-analytical, analytical, and post-analytical stages. The pre-analytical stage of specimen processing is one the factors that can affect triglyceride levels. However, field are often for test oftenis not accordance with applicable regulations. Method This research a pre-experimental design intact Group Comparison. s...

Urokinase type plasminogen activator (uPA) may influence brain pathophysiology after injury. We studied disruption of the blood-brain barrier (BBB) and changes in the vasculature after a brain stab wound in uPA-deficient, uPA receptor-deficient, and PA inhibitor-1 (PAI-1) deficient mice. The extravasation of immunoglobulin was greater in PAI-1 deficient mice; less pronounced in uPA-deficient mi...
