WebAlthough Vaccinium virgatum Aiton leaves and stems inhibit adult T-cell leukemia (ATL) cells, leaves and stems can differ between individual plants and by time and location. In this study, leaf and stem components were profiled in the same individual plant using direct-injection electron ionization-mass spectrometry (DI-EI-MS) metabolomics, with the aims … WebNew evidence is presented which shows that VHF radio echoes from auroral ionization are reflections from aspect-sensitive columns aligned with the earth's magnetic field. Previous experimental data, interpreted in terms of a distribution of ionization along a line of magnetic latitude, are shown to be consistent with this hypothesis.

"WebThe ionized form has low lipid solubility (but high water solubility—ie, hydrophilic) and high electrical resistance and thus cannot penetrate cell membranes easily. The proportion of the un-ionized form present (and thus the drug’s ability to cross a membrane) is determined by the environmental pH and the drug’s p K a (acid dissociation constant).
