effects of temperature and percentage of organic modifier were studied on retention and selectivity in rp-hplc using solvation parameter model. the system constants were determined by multiple linear regression analysis from experimental values in the retention factor for a group of different solutes with known descriptors by computer using the program spss/pc. the experimental results showed t...

background: hemophilia b is a bleeding disorder with a recessive x-linked inheritance pattern, in which the infected individuals have low levels of factor ix in their plasma. affected individuals may have bleeding episodes after trauma or spontaneously considering the plasma level of factor ix. in order to prevent these episodes and to control bleeding, they should use coagulation factor concen...

The formation resistivity factor evaluation of brine-filled reservoir rock is an essential part of electrical resistivity log interpretation in petroleum exploration. Empirical relations such as Archie’s law are widely employed to model the relationship between the formation resistivity factor and porosity. Historically, the Archie cementation exponent has been obtained from experimental labora...

Arterial thrombosis and thrombus extension involve the overlapping systems of endothelial cell reactivity, platelet function, and coagulation. Thrombotic cerebrovascular occlusions arise secondary to thromboembolism from more proximal sites, e.g., the heart and proximal internal carotid artery, or from in situ thrombosis. Thrombus generation and extension involve thrombin-mediated fibrin format...

Recently, an alternative pathway for factor XI activation has been described in which factor XI is activated by thrombin. Patients with a factor XI deficiency bleed mostly from tissues with high local fibrinolytic activity. Therefore, the role of thrombin-mediated factor XI activation in both fibrin formation and fibrinolysis was studied in a plasma system. Clotting was induced by the addition ...

the main purpose of this research paper is to compare qiujiahe formation (є1q) and longmaxi formation (s1ln) in north sichuan basin where shale gas exploration has not been fully researched, and hence represents the possibility of shale gas concentration under the complex geological conditions. based on valid laboratorial analysis, there are optimistic prospects for є1q and s1ln of research are...

introduction: having a desirable image in a market can be considered as an asset for an organization. therefore, using proper approaches, managers of such organizations must monitor and manage the image of their organizations in order to achieve their organizational goals and their customer’s satisfaction. as an important sector of every society, managers of hospitals also must try their best t...

Background: Factor VIII administration to hemophilia A patients results in an immune response (inhibitor formation) which significantly complicates the therapy. The present study was performed to determine the prevalence of inhibitor development in hemophilia A patients receiving recombinant factor VIII therapy. Materials and Methods: This was an observational descriptive study. Clotting fac...
