The neurovascular unit provides a dynamic interface between the circulation and central nervous system. Disruption of neurovascular integrity occurs in numerous brain pathologies including neurotrauma and ischaemic stroke. Tissue plasminogen activator is a serine protease that converts plasminogen to plasmin, a protease that dissolves blood clots. Besides its role in fibrinolysis, tissue plasmi...
Plasminogen activator activity was studied in bile and perfusate during extracorporeal pig liver perfusion. Plasminogen activator activity in bile was up to 58 times greater than in perfusate. A high level of plasminogen activator activity in bile was also found after the addition of urokinase to the perfusate. These results suggest that bile is the main route of active excretion of plasminogen...
Abstract Partly replacing Portland cement (PC) with lower carbon footprint cementitious materials such as ground granulated blast furnace slag (slag) is considered a practical method for reducing CO 2 emissions in the concrete industry. To mitigate slow reactivity of system and enhance early-age strength, addition chemical activator solution. However, effect on creep behaviour slag-blended conc...
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...
In this paper, we study a new physical mechanism to generate an activator field which signals the extreme margin of the contact area between an adherent cell and the substrate. This mechanism is based on the coupling between the adhesive bridges connecting the substrate to the cytoskeleton and a cytosolic activator. Once activated by adhesion on the adhesive bridges, this activator is free to d...
