    Notes: Summary Intracellular activities of sodium and calcium were determined in red cells of patients with obesity. Compared to normal people mean intracellular sodium and calcium were higher in obese patients. However, increased intracellular sodium and calcium could only be observed in those patients with obesity suffering from hypertension or showing a familial disposition to hypertension. In contrast there was no difference in intracellular sodium and calcium between obese normotensives lacking a familial disposition to hypertension and normal people. Thus, our results suggest, that the observed variations in intracellular sodium and calcium in obesity are due to an enhanced blood pressure or a familial disposition to hypertension and not specific for obesity.

    Notes: Multisite Ventricular Pacing in Heart Failure. Introduction: We studied the effects on cardiac function of pacing two right and two left ventricular sites in normal and failing hearts with a normal QRS duration. Methods and Results: Hemodynamic parameters were studied in isoflurane-anesthetized dogs with normal hearts and dogs with heart failure induced by rapid ventricular pacing. Unipolar intramyocardial electrodes were placed at the high right atrium and the apex (A) and base (B) of the left (L) and right (R) ventricles (V). Data were collected after pacing for 5 to 20 minutes. In normal dogs, without bundle branch block (BBB), pacing at either the apex or the base of the left ventricle increased cardiac output by approximately 10% compared with right ventricular apex (RVA) pacing with an AV delay of 10 msec. Positive dP/dt increased approximately 10% during four-site left and right ventricular apex and base (LRVAB) pacing compared with RVA pacing. In dogs with heart failure but without BBB, cardiac output increased by 8.5% (P 〈 0.01) during four-site ventricular pacing with AV delays of 0 and 60 msec compared with RVA pacing. Positive dp/dt increased by 23.5% (P 〈 0.001) with an AV delay of 0 msec and 9.6% (P 〈 0.001) with an AV delay of 60 msec during LRVAB pacing compared with RVA pacing. His-bundle pacing was associated with increased cardiac output compared with RVA pacing. Conclusions: We conclude that pacing simultaneously at two right and two left ventricular sites significantly improves cardiac function compared with single RVA pacing, with or without sequential AV synchrony, in dogs with rapid ventricular pacing-induced heart failure and no BBB.

    Notes: A set of powerful x-ray imaging techniques using white-beam synchrotron radiation have been developed and applied to clearly reveal and map micropipes in SiC crystals at a "magnified" level. The experimental results and the corresponding simulations demonstrate explicitly that the micropipes are pure superscrew dislocations (SSDs). Moreover, these techniques provide accurate descriptions of the detailed structure of the SSDs, including the spatial distribution of the strain fields, the magnitudes of the Burgers vectors, the dislocation senses, and the surface relaxation effects. © 1999 American Institute of Physics.

    Notes: A sub-Doppler experiment involving an effusive beam of lithium dimers and a continuous wave (cw) tunable dye laser is used to record the absorption spectrum of the B–X system. Predissociation due to tunneling through the potential barrier of the B state is studied in a small range of energy above the Li(2p)+Li(2s) dissociation limit by analyzing the shape of homogeneously broadened absorption lines and by measuring the fluorescence intensity of Li atoms. Experimental data are interpreted in the frame of a semiclassical dynamical model involving the shape of the potential barrier. Their accuracy should address an improvement of the potential shape through a full quantal dynamical model. © 1999 American Institute of Physics.

    Notes: The Cs(6D3/2)+H2→CsH [X 1Σ+(v″=0,1; J″)]+H photochemical reaction has been studied in a crossed-beam experiment with electronic excitation of Cs atoms and laser-induced fluorescence detection of CsH products. The reactive cross section is measured at a collision energy of 0.09 eV: σ(6D3/2)=0.04×10−16 cm2. The rotational distributions of CsH products measured on v″=0 for 0≤J″≤23 and on v″=1 for 0≤J″≤15 are close to statistical ones with 16% of products in v″=1. A quasi-classical 3D trajectory calculation of this reaction yields both rotational and vibrational distributions of CsH products and their angular scattering probability. The reactive cross section measured with Cs(6D3/2) excitation is an order of magnitude smaller than the cross section σ(7P1/2)=0.6×10−16 cm2, which is re-evaluated in this article. © 1999 American Institute of Physics.

    Low Temperature and Low Energy Radiofrequency Modification of Atrioventricular Nodal Slow Pathways in Pediatric Patients (1999)
    Oxford, UK : Blackwell Publishing Ltd
    Pacing and clinical electrophysiology 22 (1999), S. 0 
    Details
    ISSN: 1540-8159
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: Objectives: To report our experience using low temperature and energy in the modification of the slow pathway in pediatric patients with atrioventricular nodal reentrant tachycardia. Background: A concern in performing a slow pathway modification is the possible damage of the normal AV conduction system. Lesion size has been shown to have a linear relationship with temperature. Previous reports have used energy of 25–50 W that generate temperatures of 60C°–70°C for successful procedures. Methods: Report of results of attempted AV nodal slow pathway modification in 17 consecutive pediatric patients 〈 15 years of age at The Children's Hospital of Philadelphia from April 1995 to November 1997 using low temperature and energy. Results: There were 18 successful slow pathway modifications with 1 recurrence in 17 patients. The maximum energy used during successful lesions was 32.7 ± 13.8 W (range 15–50 W) with a mean energy of 26.4 ± 13.3 W (range 12–48 W). The peak temperature during these lesions was 55.1°C ± 4.1°C (range 48°C–64°C) with a mean temperature of 47.9°C ± 2.7°C (range 44°C–54°C). The mean number of radiofrequency lesions required for a successful modification was 5.8 ± 6.7 (median 4.0, range 1–26). Patients have been followed for 2.08 ± 0.79 years. Conclusions: Slow pathway modification can be performed successfully with a low incidence of recurrence in the pediatric patient using low energy and temperature. It is possible that this may lead to smaller lesions.

    Superscrew dislocation contrast on synchrotron white-beam topographs: an accurate description of the direct dislocation image (1999)

    Notes: A kinematic (geometrical) diffraction simulation model has been developed to provide understanding of direct dislocation images on synchrotron white-beam X-ray topographs, and has been successfully applied to illustrate the contrast formation mechanisms involved in images of micropipe-related superscrew dislocations in silicon carbide crystals. The coincidence of the simulations with the contrast features of the superscrew dislocation images, recorded using a series of synchrotron topography techniques, shows that this model is capable of revealing the detailed diffraction behavior of the highly distorted region around the dislocation core and determining the quantitative characteristics of the dislocations. The simulation technique is thus demonstrated to be a simple but efficient method for interpretation of synchrotron topographs, and may be applied to explain the topographic contrast characters of general crystal defects.

    Notes: RCC1, the regulator of chromosome condensation, is the guanine nucleotide-exchange factor (GEF) of the GTP-binding protein Ran. Its GEF activity on Ran makes it a key element in nucleo-cytoplasmic transport and cell-cycle regulation. Crystals of human RCC1 suitable for X-ray analysis have been obtained using the seeding technique in hanging drops with sodium citrate as a precipitant. The crystals diffract to 1.7 Å at 100 K and belong to the space group P1, with unit-cell parameters a = 49.5, b = 84.3, c = 84.9 Å, α = 113.0, β = 103.9,γ = 103.3°. The Matthews parameter (Vm) and the self-rotation function are consistent with three molecules in the unit cell, which is confirmed by the averaged single isomorphous replacement (SIR) electron-density map.

    Description / Table of Contents: Summary Hospital diet is an essential part of modern therapy in all medical departments. It comprises both the so-called normal diets which are prepared according to modern nutritional knowledge, dietetic foods and the various forms of artificial nutrition (nutrient-defined and chemically defined diets, parenteral and combined nutrition, i.e. enterai and parenteral nutrition). The integration of nutritional therapeutic problems into the treatment of patients requires optimal scientific and practical forms of organisation of nutrition in the clinic. For that purpose, cooperation of clinical, technical, economic and pedagogic divisions is of prime importance. The organisation of patient nutrition in the St. Georg District Hospital in Leipzig is described as a feasible model.
    Notes: Zusammenfassung Die Krankenernährung ist ein wesentlicher Bestandteil einer modernen Therapie aller medizinischen Fachbereiche. Sie umfaßt sowohl die sogenannten Normalkostformen, die nach modernen ernährungswissenschaftlichen Kenntnissen hergestellt werden, die Diätkost und die verschiedenen Formen der künstlichen Ernährung (nährstoffdefinierte — und chemisch definierte Diäten, parenterale und Kombinationsernährung, d. h. enterai und parenteral). Die Einbeziehung der ernährungstherapeutischen Prinzipien in den Behandlungsplan der Patienten erfordert wissenschaftlich und praktisch optimale Organitionsformen der Krankenernährung. Dafür ist die Zusammenarbeit klinischer, technisch-wirtschaftlicher und pädagogischer Disziplinen Voraussetzung. Als praktikables Modell wird die Organisation der Krankenernährung im Bezirkskrankenhaus St. Georg Leipzig beschrieben.
