    Notes: Summary The effect of nisoldipine on renal function after 6 weeks treatment was investigated in hypertensive patients with and without renal impairment. Nisoldipine was well tolerated and an effective antihypertensive agent when administered over a period of 6 weeks. There were no significant changes in glomerular filtration, cardiac output, plasma renin activity or serum biochemistry during nisoldipine administration. Effective renal plasma flow was unaffected by treatment in the patients with normal renal function, but in the patients with renal insufficiency, the value decreased by a mean of 12%. Nisoldipine had no major untoward effects on renal function after 6 weeks administration, but minor changes in renal haemodynamics in the patients with renal insufficiency would suggest that careful monitoring of renal function is indicated in such patients.

    Marker and radioactive silicon tracer studies of PtSi formation (1992)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 72 (1992), S. 2232-2241

    Notes: Marker and radioactive 31Si experiments have been performed to investigate atomic diffusion during PtSi formation. The marker work used a thin metallic layer (Ti, Co, Ni) as a marker. Analysis of the marker displacement indicated growth dominated by silicon diffusion (∼90%). The interpretation of data from the radioactive tracer experiments is less clear cut. However, when examined in conjunction with the marker results, it would appear that either PtSi growth took place by silicon substitutional diffusion or by a mixed interstitial mechanism (i.e., a mixture of interstitial and interstitialcy diffusion). Arguments are presented to suggest that silicon vacancy diffusion during silicide growth is the most likely mechanism. This interpretation is found to be generally consistent with other recently published work on PtSi formation.

    Pt2Si formation: Diffusion marker and radioactive silicon tracer studies (1990)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 67 (1990), S. 230-236

    ISSN: 1089-7550

    Topics: Physics
    Notes: The moving species during the formation of first-phase platinum silicide, Pt2Si, by thermal annealing is identified with inert markers (Ti, Co, Ge, As) and radioactive 31Si as a tracer. Rutherford backscattering spectrometry is utilized to monitor the flow of atoms past the marker during the silicide forming reaction, while the position of the tracer after the reaction is determined by using sputter depth profiling and radioactivity measurements. Experiments with thin-film structures employing a reference marker at the substrate silicon/amorphous silicon interface and a mobile marker near the amorphous silicon/platinum interface clearly show a shift of the latter marker towards the surface of the sample. The radioactive tracer, initially embedded in nonradioactive silicon and metal, is moved from this position and concentrates at the sample surface. The outcome of both marker and tracer studies is consistent with a picture in which platinum diffuses during the formation of Pt2Si.

    Radioactive metal tracer investigation of Pd2Si formation (1990)
    Woodbury, NY : American Institute of Physics (AIP)

    Notes: A radioactive metal tracer technique has been developed with a view to identify the dominant diffusing species and the diffusion mechanism during silicide growth.The position of a thin band of radioactive metal, originally at the silicon/metal interface, is determined after silicide formation by alternate use of Rutherford backscattering spectrometry, γ spectrometry, and Ar ion sputter etching. Application of this procedure to the formation of Pd2Si yields a 109Pd activity profile, the position and shape of which indicates that mainly silicon moves during this reaction, while the observed spreading of the profile points to some palladium vacancy diffusion. The data obtained with this approach demonstrate that the technique is well suited for the determination of the predominantly diffusing species, and confirm results of other inert marker and 31Si tracer diffusion experiments.

    Notes: The cell water balance of maize (Zea mays L., cv LG 11) andpearl millet (Pennisetum americanum L., cv MH 179) duringosmotic stress was studied non-invasively using 1H nuclearmagnetic resonance (NMR) microscopy. Single NMR parameter imagesof (i) the water content (ii) the transverse relaxation time (T2)and (iii) the apparent diffusion coefficient (Dapp)were used to follow the water status of the stem apical region duringosmotic stress. During stress there are hardly any changes in watercontent or T2 of the stem region of maize. Incontrast, the apical tissue of pearl millet showed a ∼ 30% decreaseof T2 within 48 h of stress, whereasthe water content and Dapp did not change. Thesechanges can be explained by an increase of the membrane permeabilityfor water. This conclusion is supported by results from scanningelectron microscopy, relaxation measurements of sugar solutionsand numerical simulations of the relaxation and (apparent) diffusionbehaviour of water in a plant cell.

    Notes: Abstract. Both the development and the maintenance of neurons require a great deal of active cytoplasmic transport. Much of this transport is driven by microtubule motor proteins. Membranous organelles and other macromolecular assemblies bind motor proteins that then use cycles of adenosine 5′-triphosphate hydrolysis to move these ‘cargoes’ along microtubules. Different sets of cargoes are transported to distinct locations in the cell. The resulting differential distribution of materials almost certainly plays an important part in generating polarized neuronal morphologies and in maintaining their vectorial signalling activities. A number of different microtubule motor proteins function in neurons; presumably they are specialized for accomplishing different transport tasks. Questions about specific motor functions and the functional relationships between different motors present a great challenge. The answers will provide a much deeper understanding of fundamental transport mechanisms, as well as how these mechanisms are used to generate and sustain cellular asymmetries.
