    Notes: Summary Amrinone has been shown to produce haemodynamic benefits in digitalis-treated patients. Since amrinone is a positive inotropic agent on isolated heart muscle, these benefits may mean that amrinone increases the maximal ouabain-induced increase in force of contraction, without causing toxicity. We have therefore measured, in cat right ventricular papillary muscles, the inotropic effects of ouabain, amrinone alone and amrinone with a maximally effective, non-toxic ouabain concentration (2×10−7 M). Ouabain is much more potent than amrinone (EC50-values: ouabain, 8×10−8 M, amrinone, 1–2.8×10−3 M). The highest amrinone concentration used (6×10−3 M) produced a significantly lower increase in force of contraction than ouabain (2×10−7 M) in the same muscles. After ouabain (2×10−7 M) produced a stable effect, no further increase in force of contraction was observed with any amrinone concentration. Sustained arrhythmias were observed in five of six muscles at 3×10−3 M amrinone with ouabain (2×10−7 M), but in only one of these muscles with amrinone 3×10−3 M alone. Since the positive inotropic effects of amrinone are not additive with those from a maximally effective ouabain concentration, the haemodynamic benefits seen in patients are probably due to non-cardiac effects of amrinone such as vasodilatation.

    The application of theoretical diffusion models in the presence of a catalytic reaction (1968)

    Notes: The fundamental problem in this work was to determine if methods of predicting mass transport rates in porous catalysts, developed from theory in the absence of chemical reaction, are valid in the presence of reaction. By using the ortho-para shift of hydrogen over a ferric oxide gel catalyst as the reacting system, the effective diffusivity within the catalyst was determined from kinetic data on five different particle sizes of the catalyst. This effective diffusivity was then compared with that predicted by three different procedures recently published. These procedures predicted diffusivities approximately 40% below the experimentally obtained diffusivity. Although the differences between the experimental and predicted effective diffusivities can be regarded as within the limitations of the accuracy of the predictions, the observed differences may also be caused by some form of surface transport.

    Notes: The Microstructural Physics group at the Cavendish Laboratory is actively involved in a considerable number of research projects which cover a broad range of materials science. In this paper, we describe briefly several such projects, with particular emphasis given to the application of parallel-detection electron energy loss spectroscopy (PEELS) on a scanning transmission electron microscope (STEM) to the analysis of materials such as stainless steels, catalysts, and high temperature superconductors. In addition, we describe a number of related projects that are currently being carried out in the group, particularly those which utilise and develop novel STEM imaging and analytical techniques. © 1993 Wiley-Liss, Inc.

    Notes: Embryonic development of in-vitro fertilized rabbit ova was assessed following in-vitro culture in four different serum supplemented media. A mixture of Basal Medium Eagle (BME) and Ham's F10 medium (1:1) provided better support for in-vitro development than Ham's F10, BME, or regular acidic saline (RAS). In-vitro embryonic development in the BME/Ham's F10 mixture was synchronous with in-vivo development through at least 55 hr of culture. After 54 hr of culture, embryos transferred to the oviduct of a synchronous pseudopregnant recipient were able to implant at the same rate as simultaneously transferred embryos grown in vivo. BME/Ham's F10 supplemented with 10% newborn calf serum was highly supportive of rabbit embryo development following in-vitro fertilization.

    Amorphisation of MgO single crystal specimens prepared by ion milling for transmission electron microscopy studies (1990)

    Notes: Single crystal MgO specimens having low load Vickers indentations were thinned in an ion milling machine employing a single ion gun, and their characteristics were investigated with optical microscopy and high voltage electron microscopy (HVEM). It was found that the state of cleanliness of the specimen chamber of the ion milling machine had a very marked influence on the quality of the thinned specimens. If the specimen chamber was not well cleaned before ion milling a fresh specimen, the latter tended to show amorphisation due to the deposition on the specimen of the debris left in the chamber from the previously ion-milled specimens. Such observations were made from MgO specimens ion milled in several different types of commercial ion milling machine employing a single gun. It is proposed that to obtain good-quality ion milled TEM specimens, it is important to clean the specimen chamber thoroughly prior to milling.
