    Notes: The hepatic lobules of the family Suidae are unusually large, completely surrounded by fibrous tissue, and supplied by relatively large branches of the hepatic artery. The interlobular septa carry small branches of the artery, vein and bile ducts of the adjacent portal tracts and may be regarded as attenuated extensions of the portal tracts. The hepatic lobules of Tayassuidae and Hippopotamidae lack these distinctive features.

    Localization of muscle spindles in the human Extensor indicis muscle for biopsy purposes (1974)

    Notes: The number and spatial relations of muscle spindles in the extensor indicis have been determined. Approximately forty spindles lie adjacent to the motor end plate zone dispersed rather equally through this area of the muscle with a modest increase in density among the distally originating fibers. A study of the entire innervation pattern of this muscle has also been completed.These findings have greatly facilitated the isolation of spindles for electron microscopic study and attempts to perform in vivo recording from the sensory nerves of muscle spindles in this laboratory. It is now possible, with the aid of suitable magnification and stimulating and recording devices, to more rapidly find muscle spindles relative to the gross innervation and the easily located motor end plate zone.

    Structure and innervation of the ciliary processes of the albino rabbit eyeThis research was supported in part by United States Public Health Service Research grant AM 11407. (1970)

    Notes: Various physiological and anatomical studies have suggested that the ciliary epithelium may be under the influence of adrenergic nerve fibers. This study was undertaken in an attempt to characterize the innervation of the ciliary epithelium. Both light and electron microscopy revealed that the ciliary epithelium is only sparsely innervated. In addition, the ciliary epithelium overlies a highly vascular stroma, and the distance between the large vascular channels and the ciliary epithelium is small. These features of the stroma indicate it is structurally suited for a transport function, a fact which supports earlier reports that the elaborate membrane infoldings of the ciliary epithelium are indicative of a transport function. The discrepancy between previous descriptions of the innervation of the ciliary epithelium, demonstrating complex subepithelial plexuses of adrenergic nerve fibers, and the results of the present study may be due to the fact that the fluorescence technique used in previous studies could have labelled some other tissue component in addition to adrenergic nerve fibers. Results with orcein and aldehyde fuchsin stains indicate that the disposition of elastic fibers in the ciliary processes is similar to previous descriptions of adrenergic nerve fibers as determined by fluorescent techniques.

    Quantum theoretical calculations of van der Waals interactions between molecules. Anisotropic long range interactions (1977)

    Notes: Presenting a relatively simple ab initio method to calculate full van der Waals interaction potentials between molecules, we give rules for the optimization of basis functions which permit the reliable evaluation of second order long range interactions. Closed expressions for the long range interaction energy are derived in which the orientational dependence is simplified to the utmost. Calculations show that even for molecules which have no dipole moment, such as ethylene, the strongly anisotropic electrostatic interactions are of the same magnitude as the dispersion interactions, but also that the anisotropic (“cross”) terms in the dispersion energy are about equal in size to the corresponding “quadratic” terms. Even though these anisotropic forces cancel to a large extent in the cohesion energy of the ethylene crystal, they can have important effects on some of the other crystal properties.

    Matrix elements between spin-bonded functions in a hole-particle formalism (1985)

    Notes: Closed formulas are given for Hamiltonian matrix elements between spin-bonded functions in a holeparticle formalism. The derivation is based on Wick's theorem and the use of Jucys diagrams. The final formulas are only slightly more complicated than those for bonded functions in a particle formalism.

    Notes: This is the first of a series of papers on the ab initio calculation of the second, third, and fourth derivatives of the energy with respect to nuclear coordinates. The knowledge of these derivatives yields anharmonic spectroscopic constants. Here, we present efficient formulae for the analytic evaluation of these derivatives for closed-shell SCF wave functions. We discuss our implementation of the third derivative formula, in particular the integral and vectorization procedures. Applications are reported for H2S, CHOF, and HCCF.

    Notes: A general method for calculating pi charges based on the Hückel molecular orbital (HMO) approach is incorporated into an existing scheme for calculating partial atomic charges in saturated systems. The parametrization of the Hückel coulomb and resonance integrals is given based on (a) the CNDO pi densities and (b) the observed molecular dipole moments. The results for these two schemes are compared both with other theoretical methods and also with the observed dipole moments of a variety of conjugated and aromatic compounds. The dipole moment (DM) parametrization gives in general more consistent results and is to be preferred. The compounds studied include substituted olefins and aromatics (with substituents R, F, Cl, Br, I, OR), aldehydes, ketones, acids, esters, amides, and the heterocyclic ring systems of furan, pyrrole, pyridine, and indole.

    Notes: The distribution of total polyadenylated RNA and mRNAs from the β-actin, fibronectin, and cytokeratin Endo A genes was examined in preimplantation mouse embryos using in situ hybridization of riboprobes to RNA in sections of embryos. Polyadenylated RNA was found in the cytoplasm of all cells of blastocyst-stage embryos, whereas the specific mRNAs displayed three distinct patterns of expression: uniform throughout the embryo (β-actin), enriched in the inner cell mass (fibronectin), and enriched in the trophectoderm (Endo A). In eight-cell embryos, the polyadenylated RNA was more concentrated in nuclei than in the cytoplasm (as noted previously), although this was not the case in blastocysts, nor was it true for the specific mRNAs that were examined. These experiments demonstrate that there is localized gene expression in the early mouse embryo, which correlates with the formation of the trophectoderm and the inner cell mass.
