    Notes: Abstract The character of the current controversy over geneticallymodified (GM) agriculture, typified by protesters' use of emotivesymbolism, has been largely inspired by the Green movement'snon-governmental organizations and political parties. This articleexplores the deeper philosophical and spiritual motivations of the Greenmovement, to inquire why it is implacably opposed to GM agriculture. TheGreen movement's anti-capitalism, exemplified by the hate-symbol statusof Monsanto as the company pioneering GM crops, is viewed within thewider context of alienation in the modern era. A complex of meanings isseen in Frankenstein as the focal symbol of GM protests, includingperceptions of risk, fears of the remixing of living identities seen ingenetic engineering, and resentment at the spiritual nihilism of thereduction of life to the digital code of DNA. By contrast, RobertGoodin's Green Theory of Value, which postulates the deep psychologicalimportance of nature in locating the self in a meaningful context largerthan ourselves, can explain the power of the Green symbol of thethreatened environment, Gaia. The advent of GM agriculture seems toimply that capitalism and technology can now enframe nature itself,leaving a world devoid of natural myth or meaning, with no escape fromthe alienation and nihilism of modernity. The central question posed forprotagonists of the GM debate is whether their agenda is based on thesepowerful but mythical conceptions of the environment, or whetherpreservation of the real environment is their primary ethic.

    Notes: Human neuroblastoma cells (clone SHSY-5Y) induced to differentiate by 12-O-tetradecanoylphorbol-13-acetate (TPA) are shown to possess properties characteristic of mature ganglion cells. Elevation of the external K+ concentration, exposure to Ca2+ ionophore A23187, and acetylcholine all stimulate the release of preloaded 3H-noradrenaline in the presence but not in the absence of added Ca2+. Acetylcholine causes a fall in the 86Rb+ or 14C-TPMP equilibrium potential across the plasma membrane and stimulates 86Rb+ efflux. These responses are prevented by atropine. Acetylcholine and muscarine but not nicotine stimulate an increase in 45Ca2+ influx, an effect blocked by atropine. None of these responses have been observed in nondifferentiating cells. Muscarinic receptors, however, as measured by the binding of tritiated quinuclidinyl benzilate (3H-QNB), were present to a similar extent in control and differentiated cells. Both cell types also exhibit an accelerated release of Ca2+ in response to acetylcholine, but the control cells were at least 1 order of magnitude more sensitive to the agonist.

    Notes: Muscarinic receptor-linked increases in intracellular free Ca2+ as measured with quin-2 and Ca2+ release from monolayers of cells have been measured in the human neuroblastoma cell line SH-SY5Y. Induction of differentiation with the phorbol ester 12-O-tetradecanoylphorbol-13-acetate (TPA) leads to a decrease in the sensitivity of the cells to low concentrations of agonists with respect to the induced increase in cytosolic free Ca2+ and stimulation of Ca2+ efflux. No decrease in agonist binding affinity was observed when the displacement of a labelled antagonist, 3H-NMS, by a non-labelled agonist was studied.
