    Notes: Abstract An all valence electron theory, based on SCF perturbation theory, for the excited state energies of crystals with energy bands of low to intermediate dispersion is presented. It is shown that molecular theory leads to results equivalent to those of the valence bond treatments of Davydov and Choi, Silbey, Jortner, and Rice. The advantages of the proposed MO approach are twofold. First, the explicit inclusion of all valence electrons permits an unambiguous calculation of any structural changes that may accompany electronic excitation. Second, and more important, it provides a convenient method for calculating the excited states of crystals composed of relatively strongly interacting molecules, such as those within lattices of hydrogen bonded or charge transfer crystals.

    Localization of tritiated prostaglandin E1 in rat adrenal cortices (1973)

    Notes: Summary To determine whether or not prostaglandins enter adrenocortical parenchymal cells,3H-PGE1 was injected intravenously into rats. In histological preparations, grains denoting activity were noted in intracellular lipid droplets and nuclei and in sinusoids. At the fine structural level, activity was observed in lipid droplets, mitochondria, the agranular endoplasmic reticulum, nuclei and the plasma membrane. Biochemical lipid analyses of the adrenals revealed activity in the cholesterol and cholesterol ester fractions. Large amounts of unaltered3H-PGE1 and its degradation products were also present. Compared to the liver, the adrenal was more effective in degrading prostaglandin, when expressed on a weight basis. The possible roles of the organelles in PGE1 degradation and in prostaglandin-related hormone synthesis are discussed.
