conclusions the most effective enhancer for aha and ha were liquid paraffin and glycerol, respectively. the most effective surfactant for both aha and ha was tween 80. the effects of the enhancers were increased by prolonging the exposure time. results after 1.5 and 12 hours, the maximum permeated amount of aha were 89.8 and 342.5 mg, respectively, which related to the formulations with liquid ...
The acetohydroxamic acid (AHA), a potent inhibitor of urease, inhibits soybean urease competitively and reversibly. The I 50 and K i value for AHA were 900 M and 0.053 mM, respectively at pH 7.0, 37 °C. The variation in pH over the pH 6 9 affected K i and therefore binding of AHA in the active site. The affinity of AHA for the active site decreases with lowering of pH (below the pK a value of ...
Acquired haemophilia A (AHA) is caused by the development of factor (F)VIII autoantibodies, demonstrating type 1 or type 2 inhibitory behaviour, and results in more serious haemorrhagic symptoms than in congenital severe HA. The reason(s) for this remains unknown, however. The global coagulation assays, thrombin generation tests and clot waveform analysis, demonstrated that coagulation paramete...
The subjective Aha! experience that problem solvers often report when they find a solution has been taken as a marker for insight. If Aha! is closely linked to insightful solution processes, then theoretically, an Aha! should only be experienced when the correct solution is found. However, little work has explored whether the Aha! experience can also accompany incorrect solutions ("false insigh...
This study examined the transport behavior of Aldrich humic acid (AHA) in low natural organic carbon content sediment contaminated with tetrachloroethene (PCE), for comparison to a nonionic surfactant mixture previously examined in the same system. Tracking of individual molecular weight (MW) fractions of AHA was attempted by UV absorbance, followed by conversion to mass of carbon using specifi...
Autoimmune hemolytic anemia (AHA) is a common complication in chronic lymphocytic leukemia (CLL). The UK LRF CLL4 trial is the largest prospective trial in CLL to examine the prognostic impact of both a positive direct antiglobulin test (DAT) and AHA. Seven-hundred seventy-seven patients were randomized to receive chlorambucil or fludarabine, alone or with cyclophosphamide (FC). The incidence p...
