    Fine structure of the nasal barbel of the channel catfish, Ictalurus punctatus (1978)

    Notes: Ultrathin sections of the nasal barbel of the channel catfish, Ictalurus punctatus, were studied in the electron microscope and the fine structure was compared to that of barbels of other teleosts and to the mandibular (dentary) barbels of I. punctatus. While the overall histology of the nasal barbel is similar to that of barbels described previously, this study revealed far greater cellular complexity and variability than was previously reported. A layer of stratified epidermal cells rests upon a connective tissue dermis containing a cartilage rod, a large number of nerve fibers and numerous blood vessels, fibroblasts and pigment cells. Taste buds are present in the epidermal layer. This layer was found to contain probably 16 kinds of cell types, several of which may represent transitional stages, in addition to taste bud cells. Observations were made pertaining to innervation and cell types in the taste buds. A new terminology for designating the barbels of I. punctatus is suggested.

    Ultrastructure of the posterior half of the intestine of the channel catfish, Ictalurus punctatus (1975)
    New York, NY : Wiley-Blackwell

    Notes: The posterior half of the channel catfish intestine has a similar histological organization to that of other teleost fishes. This region is organized into a muscosa, a submucosa, a double layered muscularis and a serosa. A “stratum compactum” of dense connective tissue was confirmed for the submucosa. In its histology and cytology, the midgut resembles the hindgut, except that in the hindgut the muscularis is thicker, the microvilli are shorter, there are fewer absorptive inclusions in the columnar cells and there are more goblet cells. With the exception of the serosa, the tissue layers of the intestine of the 6 cm juvenile catfish are fully developed. The most notable difference between the intestines of the juvenile and adult catfish occurs in the columnar epithelial cells. The mucosal cells of the juvenile catfish contain an abundance of large clear vacuoles while the mucosal cells of the mature catfish contain smaller dense granules. With few exceptions, the ultrastructural details of the cells in the catfish intestine are identical to those of the same cell types of the mammalian intestine.

    Some properties of a protease (subtilisin BPN′) immobilized to porous glass (1975)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 17 (1975), S. 1783-1795

    Notes: Subtilisin BPN′ was immobilized to porous glass via isothiocyanate coupling. The pH optimum of the enzyme was shifted to the alkaline side on binding. This effect was more pronounced with ethyl lactate than with N-tosyl arginine methyl ester (TAME). Presumably, the shift is a reflection of the negative charge on the surface of the glass. The Michaelis constant and Vmax of soluble subtilisin BPN′ with TAME were two and one orders of magnitude, respectively, lower than with ethyl lactate. Vmax, calculated per g of active enzyme, with TAME as the substrate was not affected by immobilization, while Vmax with ethyl lactate decreased greater than tenfold. The apparent KM decreased on immobilization with ethyl lactate as substrate and increased with TAME. Results are explained in terms of diffusional resistance and a possible attraction of ethyl lactate to the glass surface. Active site titration indicated that about 25%, of the immobilized enzyme was active.

    Notes: The bacterial degradation of catechol, 3-methylcatechol, 2,3-dihydroxy-β-phenylpropionic acid, and protocatechuic acid has been studied in detail. From the results obtained a general sequence has been proposed for the microbial oxidation of dihydroxy aromatic compounds.

    The viscosity of liquid metals (1966)
    Hoboken, NJ : Wiley-Blackwell

    Notes: In order to make the kinetic theory of liquid viscosity tractable, an approximate from is suggested for the perturbation of the radial distribution function of a monatomic liquid by a nonuniform flow field. Substitution of this form into the microscopic expression for the pressure tensor yields an equation for liquid viscosity in terms of the equilibrium distribution function and the interatomic potential energy function. This equation establishes the basis for a corresponding states correlation of the viscosity of liquid metals based on atomic parameters.The viscosity data for twenty-one molten metals are made to fall on a single curve by the adjustment of one microscopic parameter. It is found that this empirically determined parameter has the proper fundamental significance. Therefore it is possible to estimate it independently and to use the general correlation for estimating the viscosity of a metal for which data are not available. Also it is suggested that the atomic parameters determined from viscosity data in this way might be used to correlate other properties of the liquid metals.

    Volume changes accompanying the thermal denaturation of deoxyribonucleic acid. I. Denaturation at neutral pH (1969)
    New York : Wiley-Blackwell

    Notes: Dilatometric measurements were made to determine the change in apparent specific volume ϕ of DNA resulting from thermal denaturation in neutral solution, ϕ increased continuously with temperature in the range 10-85°C. No deviations from a monotonically rising curve were observed in the ϕ versus temperature profile in the region of the melting temperature. The results are interpreted in terms of a partial loss of the preferentially bound DNA hydration shell. The nature of the well known buoyant density difference between native and denatured DNA was investigated by evaluating the densities in a series of cesium salt gradients at constant temperature. Extrapolation of the results to zero water activity indicates that the partial specific volumes of anhydrous native and denatured DNA are equal. The density difference at nonzero water activities is attributed to decreased hydration in the denatured state. The absence of a related change in ϕ accompanying the denaturation in the dilatometric experiments suggests that the probable volume change associated with loss of bound water during denaturation is accompanied by other compensatory volume effects. The possible nature of these volume effects is discussed.

    A study of the growth of normal and iodinated collagen fibrils in vitro using electron microscope autoradiography (1977)
    New York : Wiley-Blackwell

    Notes: Electron microscopic autoradiographic observations on collagen fibrils grown in vitro allow growth rates in the N- and C-terminal directions to be measured on individual fibrils. Such observations, made on normal and iodinated collagen, show that normal fibrils grow at both ends (although rather more rapidly at the N-terminal end), whereas fully-iodinated collagen fibrils grow only at the N-terminal end.Measurements of growth rates at different temperatures provide estimates of the activation enthalpy (ΔH≠) and entropy (ΔS≠) of precipitation for the two types of collagen. Solubility measurements have also yielded values for the thermodynamic enthalpy (ΔH) and entropy (ΔS) of precipitation. Results show that the activated (rate-limiting) state is characterized by a large positive ΔH≠ and ΔS≠ similar in magnitude to the ΔH and ΔS of transition from solution to fibril. It is also concluded that the different rates of precipitation of normal and iodinated collagen cannot be explained in terms of fibril formation requiring ionization of the tyrosine residues.
