Webb16 nov. 2004 · The data provide first proof of concept for upregulation of endogenous EPO and erythropoietic responses in humans by a specific HIF-PH inhibitor. High-altitude hypoxia stimulates erythropoiesis in anemic hemodialysis patients. Similarly, intermittent exposure to hypobaric hypoxia elevates EPO and stimulates erythropoiesis in normal … Webb21 jan. 2014 · The kinetics of urea hydrolysis catalyzed by urease, mainly in the absence of buffers by use of the self-buffer effect of the products, was investigated. The effect of pH, temperature, and concentration of enzyme, substrate, product, salt ions, and buffers on the kinetic behavior of urease was examined. A kinetic model of a modified Michaelis …

Webb28 apr. 2024 · However, while de-acidification of the lysosomal lumen occurs rapidly , only longer term treatment of human cells with CQ or BafA results in impairment of mTORC1 activity (Figure 1 and Supplementary Figure S2), suggesting such inhibition is a consequence of alkalinisation rather than altered pH being the proximal cause. Webb22 apr. 2006 · Inhibition was most prominent at pH 4.5, at which ∼30% of enzyme activity was lost in the presence of 10 mM SC, followed closely by that at pH 4.0 with a 26% reduction in PPO activity. The inhibition mode was determined using Dixon and Lineweaver−Burk plots, which established SC to be a mixed inhibitor of apple PPO for …
