Treatment of HIV-1-infected individuals with a combination of anti-retroviral agents results in sustained suppression of HIV-1 replication, as evidenced by a reduction in plasma viral RNA to levels below the limit of detection of available assays. However, even in patients whose plasma viral RNA levels have been suppressed to below detectable levels for up to 30 months, replication-competent virus can routinely be recovered from patient peripheral blood mononuclear cells and from semen. A reservoir of latently infected cells established early in infection may be involved in the maintenance of viral persistence despite highly active anti-retroviral therapy. However, whether virus replication …

Artemisinin-based combination therapies (ACTs) may select for malaria parasites with decreased drug sensitivity. We studied the sensitivity of parasites from children enrolled in treatment and prevention trials in Tororo, Uganda from June, 2010 to February, 2012. When Plasmodium falciparum malaria was diagnosed, blood was obtained, parasites (286 isolates) were cultured with serial dilutions of chloroquine (CQ), monodesethylamodiaquine (AQ), quinine (QN), dihydroartemisinin (DHA), lumefantrine (LM), or piperaquine (PQ) for 72 h, and ex vivo sensitivities were assessed by HRP-2-based ELISA. Sensitivities (nM) to CQ (median IC50 486.2; IQR 206.5-748.8), AQ (83.3; 58.4-132.4), PQ (20.3; 7.6-47.5) and QN (126.4; 74.9-196.3) varied widely; …


Red Blood Cell Aggregation Parameters Measured By Capillary Tube Aggregometer Using Venous And Capillary Blood Samples, Michael Simmonds, R. Christy, Sonya Marshall-Gradisnik, Herbert Meiselman, Oguz Baskurt Oct 2012

Red Blood Cell Aggregation Parameters Measured By Capillary Tube Aggregometer Using Venous And Capillary Blood Samples, Michael Simmonds, R. Christy, Sonya Marshall-Gradisnik, Herbert Meiselman, Oguz Baskurt

The extent of red blood cell (RBC) aggregation has widely been accepted as a reliable indicator of inflammatory processes. The ability to measure RBC aggregation indexes in capillary blood samples may simplify the application of the test and may bring advantages in its clinical usage as well as application in field studies. This study compared RBC aggregation indexes measured in venous and capillary blood samples using a newly developed capillary tube aggregometer. Although strong correlations between agreegation indexes measured in capillary and venous samples were detected, the indexes measure in venous samples were higher compared to capillary samples, thus indicating …
