Specificity of synergistic coronary flow enhancement by adenosine and pulsatile perfusion in the dog
Amid an increasing number of reports in the literature concerning epithelial barrier enhancement by various nutrient compounds, there has never been a study performing side-by-side comparisons of these agents in a single epithelial model. We compare five nutrient compounds (previously reported in various epithelial models to enhance barrier function) regarding their ability to increase transepi...
The blast progenitors in acute myelogenous leukemia grow in response to hematopoietic growth factors (HGFs), and their sensitivity to antileukemic drugs is influenced by HGFs. We report the effects of stem cell factor (SCF) on the growth and sensitivity to 1-beta-D-arabinofuranosylcytosine (Ara-C) of blast progenitors in acute myelogenous leukemia. SCF stimulated both colony formation and self-...
The concept of plant defense using toxic mineral elements originated as an explanation for extremely elevated concentrations of some elements (termed hyperaccumulation) in some plant tissues. The Defensive Enhancement Hypothesis suggests that hyperaccumulation evolved because, after an initial defensive benefit accrued from a relatively low initial concentration, increased concentration of an e...
