Incorporation of weak acids as pH modifiers enhances the release of weakly basic drugs in higher pH environments by reducing the microenvironmental pH (pHM).
PNT1A cells, also from normal prostate epithelia, occupy an intermediate position in that PCho and Cho are released in about equal proportions, whereas PKC activation stimulates Cho metabolite release more weakly than is detected with PNT2C2 cells.
From the experiments using the specific MAPKs inhibitors, we concluded that OSM-mediated IL-6 release is weakly dependent on the ERK1/2 or JNK signaling, but depended mostly on the p38 signaling pathway.
Similar findings were obtained from the salt dependences of the steady-state kinetic parameters, where the diffusion-controlled kcat/ Km showed a salt dependence similar to kon, while kcat (limited by product release) was weakly dependent on salt.
These findings may provide a new approach to the host-guest chemistry of cucurbit[n]urils for the development of a controlled release technology of weakly acidic agrochemicals to plant systems.
The release of IFNγ was weakly inhibited by 100 nM CGRP in lymphocytes from SNS-gp130−/− mice, but strongly enhanced by IL-6/sIL-6R, an effect, attenuated by CGRP (Fig. 8c).
The first, initiating at ∼200 °C in air and with apparent activation energy (Ea) of ∼111 kJ/mol, relates to the oxidation and release of interstitial and weakly-bonded carbon nitrogen molecules.
It predicts solvent release under compression for both weakly charged and neutral gels, being more pronounced for polyelectrolyte hydrogels.
She finally made it to NBC Nightly News over a month and a half after her RNC speech, weakly promising to release her medical records really, really soon.
The higher initial burst release is mainly attributed to weakly bound or adsorbed drug to the relatively larger surface of nanoparticles.
