Autor: J. M. Curtis, R. K. Boyd, P. G. Sim, S. M. Crain, J. Macdonald, D. Thomas, G. M. McCully, M. D. Leblanc

Publikováno v: Polycyclic Aromatic Compounds. 9:217-224

The Marine Analytical Chemistry Standards Program (MACSP) of the National Research Council of Canada produces certified reference materials for several analytes, including PAHs, in marine matrices. Four harbour sediment CRMs are available, HS-3,4,5,

Copper immobilized on silica has been investigated as an adsorbent for the fractionation of polycyclic aromatic compounds (PACs) into different compound classes. an open column chromatographic packing based on copper (II) bound to a silica substrate

Nerve growth factor rapidly prolongs the action potential of mature sensory ganglion neurons in culture, and this effect requires activation of Gs-coupled excitatory kappa-opioid receptors on these cells

Application of low concentrations (pM-nM) of NGF to mouse dorsal root ganglion (DRG)-spinal cord explants in long-term organotypic cultures rapidly prolongs the duration of the Ca(2+)-dependent component of the action potential (APD) in a major subse

After GM1 ganglioside treatment of sensory neurons naloxone paradoxically prolongs the action potential but still antagonizes opioid inhibition

Autor: S M, Crain, K F, Shen

Publikováno v: The Journal of pharmacology and experimental therapeutics. 260(1)

Low (nanomolar) concentrations of opioid agonists prolong the calcium-dependent component of the action potential duration (APD) of many dorsal root ganglion (DRG) neurons, whereas higher (micromolar) levels shorten the APD. Both effects are blocked

Dynorphin prolongs the action potential of mouse sensory ganglion neurons by decreasing a potassium conductance whereas another specific kappa opioid does so by increasing a calcium conductance

Autor: K F, Shen, S M, Crain

Publikováno v: Neuropharmacology. 29(4)

Previous studies have reported that large (microM) concentrations of kappa opioids, e.g. dynorphin and 3,4 dichloro-N-methyl-N-(2-[1-pyrrolidinyl]-cyclohexyl)benzene-acetamide (U-50,488H), shorten the duration of the calcium component of the action p
