    Notes: A pathogenic Pseudomonas syringae strain resistant to rifampicin and nalidixic acid was sprayed upon and colonized maple twigs and perennial ryegrass. The inoculated twigs were sampled at intervals of 2-3 weeks from July 1985 to September 1986, and epiphytic populations of the marked strain recovered during this time ranged from undetectable to 104 colony-forming units/g. The results showed that this strain of P. syringae could overwinter on maple twigs and potentially serve as a source of inoculum in the spring. Aerial dispersal was also investigated. The marked strain inoculated onto grass growing in pots was detected on medium in inverted petri plates, on maple leaves and with an Andersen sampler positioned from 12 to 100 cm above the grass. The number of detectable cells that dispersed vertically upwards was low even in the presence of wind, rain, or irrigation water. The marked strain inoculated onto maple branches was isolated from grasses under the inoculated trees, showing that P. syringae was dispersed downward. Lateral dispersal of the marked strain from inoculated to uninoculated trees was not detected. The identity of the antibiotic-resistant strain isolated from the trees and grasses was confirmed by DNA restriction-fragment profile analysis.

    Self-Assessment: A Personalized Approach to Nursing During Pregnancy (1986)
    Oxford, UK : Blackwell Publishing Ltd

    Topics: Medicine
    Notes: SUMMARYA Prenatal Self-Assessment questionnaire was developed to aid in personalizing nursing care in a large medical center prenatal clinic. The questionnaire complements the standard prenatal record, which is intended primarily to document medical findings and treatment. The tool was used with more than 100 mothers who were receptive to this approach. The women's responses to questions about their feelings and thoughts concerning their pregnancies facilitated identification of potential problems and provided a basis for individualized and comprehensive care.

    Interaction between a peat carrier and bacterial seed treatments evaluated for biological control of the take-all diseases of wheat (Triticum aestivum L.) (1989)

    Notes: Summary Field plots were established in Indiana, Oregon, and Montana to evaluate the potential for biological control of various strains of bacteria as seed treatments to reduce the severity of take-all root, crown, and foot rot of wheat. The bacteria were grown in liquid broth Cas-amino acid broth media, mixed with finely ground peat, and applied to seed with methyl cellulose as a glue just before planting in field soils conducive for severe take-all. Autoclave-sterilized peat (minus bacteria) seed treatments increased take-all, immobilized Mn, and reduced plant vigor and grain yields. These effects were intensified when the pH of the natural peat was adjusted from 5.2 to 7.0 with CaCO3. The ability of the bacterial strains to counteract this peat-induced predisposition to take-all varied, and was influenced by planting site, genetic tolerance of the cultivar, and N treatment. Although the strains differed in their ability to suppress the peat-induced take-all, none of the isolates fully nullified the deleterious effects of the peat carrier. It is clear from this study that the carrier used with potential biological-contol agents may have a greater influence on disease than the biological agent.

    Contact angle of E and borosilicate glasses in different atmospheres (1985)
    Springer
    Journal of materials science 20 (1985), S. 1748-1752

    Notes: Abstract The contact angle of E and borosilicate glasses in various atmospheres such as air, steam, glycols, etc, show that the ambient atmosphere significantly affects the wetting behaviour of these glasses with platinum 20% rhodium alloy. The change in the contact angle is attributed to the bond formation between the cations and anions in the substrate, glass and atmosphere. Steam and oxygen which increase the non-bridging oxygens in the glass as well as increase the negativity of the glass surface increase wetting. Glycols and glycerins reduce non-bridging oxygens and increase the surface positivity groups which reduce wetting. As the requirement of oxygen for complete oxidation of atmospheric combustibles increases, the wetting increases and consequently the contact angle decreases.

    Surface thermodynamic properties and chromatographic and salting-out behavior of IgA and other serum proteins (1985)

    Notes: Abstract By means of contact angle determinations with two liquids, on hydrated as well as on dried protein layers, the long-range and the short-range contributions to the protein surface tensions, and from these the protein (ΔG 131) and the protein-ligand (ΔG 132) free energies of interaction in aqueous media, were determined. For human serum albumin (HSA), human IgG, and human IgA, the differences between ΔG 131 HYDRATED and ΔG 131 DRY were connected with the behavior of these proteins in low concentrations of (NH4)2SO4 versus saturated (NH4)2SO4 solutions. By interpolation, intermediate points are found that correlate well with the known salting-out properties of these three proteins. On the basis of the data, it is predicted that the precipitation of IgG by 1/3 saturated (NH4)2SO4 is preventable, or reversible, by the admixture of 15% dimethylsulfoxide; both predictions are confirmed experimentally. From the ΔG 132 values found, it is shown that HSA and IgG should attach to phenyl ligands under physiological conditions, but that IgA is so hydrophilic that it only can adhere to phenyl ligands after partial dehydration brought about when admixed with 1 M (NH4)2SO4. Closer analysis of the values obtained for the long-range and short-range components of the surface tensions of HSA, IgG, and IgA allow deeper insight into their functional, chemical, and physicochemical properties.

    Comparison of steady-state electrophysiological properties of isolated cells from bullfrog atrium and sinus venous (1986)

    Notes: Summary Single electrode whole cell voltage-clamp experiments and frequency domain analyses have been used to study and compare the K+ currents in enzymatically dispersed single cells from the atrium and the sinus venosus (pacemaker region) of the bullfrog heart. Admittance measurements made near the ‘resting’ or zero-current potential yield data from which the equivalent circuit of each cell type may be obtained. Data from both atrial and pacemaker cells are well-fitted by a model consisting only of parallel resistance-capacitative elements, as predicted from their micro-anatomy. Neither of these amphibian cardiac cells contain a transverse tubule system (TT) and both have very little sarcoplasmic reticulum (SR). These results complement and extend two earlier investigations: (i) Moore, Schmid and Isenberg (J. Membrane Biol. 81:29–40, 1984) have reported that in guinea pig ventricle cells (whichdo contain an internal membrane system consisting of transverse tubules and a substantial SR) the SR may be electrically coupled to the sarcolemma; (ii) Shibata and Giles (Biophys. J. 45:136a, 1984) have shown that although bullfrog atrial cells have an inwardly rectifying back-ground K+ current, $$I_{K_1 } $$ , pacemaker cells from the immediately adjacent sinus venosus do not. Data from admittance measurements also provide evidence that a TTX-insensitive inward Ca2+ current is activated in the pacemaker range of potentials.

    Sequestration of cardenolides inOncopeltus fasciatus: Morphological and physiological adaptations (1986)

    Notes: Abstract The morphological and physiological adaptations associated with sequestration of cardenolides by the lygaeidOncopeltus fasciatus are summarized and discussed. Cardenolides are efficiently accumulated inO. fasciatus; however, the insect does not appear to suffer any physiological cost as a result of handling large amounts of these plant toxins. Morphological adaptations of the insect include a modified integument composed of a double layered epidermis with an inner layer (the dorsolateral space) specialized for cardenolide storage. Special weak areas of the cuticle are found on both the thorax and abdomen, which rupture when the insect is squeezed, resulting in the cardenolide-rich contents of the inner epidermal layer being released onto the body surface in the form of discrete spherical droplets. Physiological adaptations include selective sequestration of food plant cardenolides, concentration of cardenolides in the dorsolateral space, passive uptake of cardenolides at the gut and dorsolateral space requiring little energy output, reabsorption of secreted cardenolides by the Malpighian tubules, high in vivo tolerance to cardenolides, and the presence of cardenolide-resistant Na,K-ATPases.
