Protonix Proton Pump Inhibitor

protonix proton pump inhibitor
    proton pump
  • An active transport mechanism in cell membranes that uses ATP to force hydrogen ions out of a cell, generating a membrane potential in the process.
  • protein in the membrane of the stomach that secretes hydrochloric acid.
  • A proton pump is an integral membrane protein that is capable of moving protons across the membrane of a cell, mitochondrion, or other subcellular compartment.
  • A thing that inhibits someone or something
  • A substance that slows down or prevents a particular chemical reaction or other process, or that reduces the activity of a particular reactant, catalyst, or enzyme
  • a substance that retards or stops an activity
  • (inhibitory) restrictive of action; "a repressive regime"; "an overly strict and inhibiting discipline"
  • A gene whose presence prevents the expression of some other gene at a different locus
  • (inhibit) suppress: to put down by force or authority; "suppress a nascent uprising"; "stamp down on littering"; "conquer one's desires"

Alexander Pines is the Glenn T. Seaborg Professor of Chemistry at the University of California, Berkeley, Senior Scientist in the Materials Sciences Division of the Lawrence Berkeley National Laboratory (LBNL), Faculty Affiliate at QB3-the California Institute of Quantitative Biomedical Research, and a Core Member of the UCB/UCSF Graduate Group in Bioengineering. Pines is a pioneer in the development and applications of nuclear magnetic resonance (NMR) spectroscopy. In his early work, he demonstrated time-reversal of dipole-dipole couplings in many-body spin systems, and introduced high sensitivity, high resolution NMR of dilute spins such as carbon-13 in solids (proton-enhanced nuclear induction spectroscopy), thereby helping to launch the era of modern solid-state NMR in chemistry. He also contributed to the areas of multiple-quantum spectroscopy, adiabatic sech/tanh inversion pulses, zero-field NMR, double rotation and dynamic-angle spinning, iterative maps for pulse sequences and quantum control, and the quantum geometric phase. His combination of optical pumping and cross-polarization made it possible to observe enhanced NMR of surfaces and the selective "lighting up" of solution NMR and magnetic resonance imaging (MRI) by means of laser-polarized xenon. credit: Lawrence Berkeley Nat'l Lab - Roy Kaltschmidt, photographer XBD200708-00367-03.TIF
SNS Mercury Target
SNS Mercury Target
Spallation Neutron Source, Oak Ridge National Laboratory. (This is a real backup target, not a model.) Fourteen tons of mercury are pumped continuously through an enclosed, piped system. Protons strike the target and the resulting neutrons are channeled into beamlines for researchers. Fast, high-energy neutrons are slowed by cooling—either with water or a liquid-hydrogen cold source, depending on energies desired—to make them more usable for experiments. Mercury was chosen for the target because it is not damaged by radiation, as are solids; it has a high atomic number, making it a source of numerous neutrons; and because it is liquid at room temperature, it is better able than a solid target to dissipate the large, rapid rise in temperature and withstand the shock effects arising from the rapid high-energy pulses.
