    Renal histopathology in fatal cases of diarrhoea-associated haemolytic uraemic syndrome (1997)

    Notes: Abstract.  Autopsy material was examined from British children dying early in the course of haemolytic uraemic syndrome (HUS). These presented after 1983, the period in which verocytotoxin-producing Escherichia coli (VTEC) infection was confirmed as the leading cause of diarrhoea-associated (D+HUS) in the United Kingdom. Of 18 cases referred for this study, 3 were found on review to have no history of a diarrhoeal prodrome (D-HUS). In the D+ patients, the median duration from onset of diarrhoea to death was 8 days (range 4–42 days). VTEC infection was confirmed in 6 cases. All had neutrophilia at presentation (median 21, range 15–49.8 × 109/l). The 15 cases had uniform pathological features, consisting of glomerular thromboses and congested rather than ischaemic glomeruli. Arteriolar thromboses were common at the hilum of glomeruli and were sometimes also seen proximally, including in interlobular arteries. There were cortical infarcts in 5 cases with extensive thrombosis. Cases were demonstrated to have significantly greater numbers of neutrophils expressed per 100 glomeruli than controls, when counted using immunohistological stains to neutrophil elastase and CD15. This study showed uniformity of the renal changes in D+ HUS and gave further evidence of the importance of neutrophils in the pathogenesis of the disease.

    Role of nitric oxide in a toxin-induced model of haemolytic uraemic syndrome (2000)
    Springer
    Pediatric nephrology 14 (2000), S. 1066-1070 
    Details
    ISSN: 1432-198X

    Notes: Abstract  The role of nitric oxide in the pathogenesis of glomerular thrombotic microangiopathy was explored using an established rat model in which ricin with or without lipopolysaccharide induced glomerular thrombosis. Ricin alone caused a small rise in the plasma concentration of nitric oxide (control 9.2±0.7 µM, ricin 23.3±6.3 µM at 7 h). This increase occurred after the development of glomerular thrombosis. Nitric oxide synthase (NOS) activity in the kidney showed no significant change from control values (control 5.66±2.7 pmol/min per ml homogenate, ricin 7.52±1.8 pmol/min per ml homogenate, total activity). When ricin and lipopolysaccharide were administered together, calcium-independent NOS activity increased whereas calcium-dependent activity decreased (1.22±2.6 pmol/min per ml homogenate). The increase in calcium-independent NOS activity correlated with a high plasma concentration of interleukin-1β in the ricin plus lipopolysaccharide group (4,036.83±1,001.5 pg/ml). These data indicate that thrombus formation in a rat model of haemolytic uraemic syndrome is independent of the effects of nitric oxide.

    On the construction and numerical solution of transmission-line and lumped network models of Maxwell's equations (1980)

    Notes: It is sometimes convenient to express a numerical algorithm in terms of a network model. The physical picture given can often help the engineer to visualize the properties of the method. In field problems, a lumped network model corresponds to a space discrete field while a transmission-line model corresponds to a field which is discrete in space and time. In this paper, the relationship is given between the lumped network models and transmission-line network models used in the steady-state solution of Maxwell's equations in two and three space dimensions. The use of dual networks is also discussed. An analysis is given for the velocity of waves travelling in any direction across the networks and this is used to compare the accuracy of the models. The use of diakoptics or substructures for the solution of large networks is outlined and this is illustrated by a compound two-dimensional example.

    Stable and time-dissipative finite element methods for the incompressible Navier-Stokes equations in advection dominated flows (1995)

    Notes: This paper examines a new Galerkin method with scaled bubble functions which replicates the exact artificial diffusion methods in the case of 1-D scalar advection-diffusion and that leads to non-oscillatory solutions as the streamline upwinding algorithms for 2-D scalar advection-diffusion and incompressible Navier-Stokes. This method retains the satisfaction of the Babuska-Brezzi condition and, thus, leads to optimal performance in the incompressible limit. This method, when, combined with the recently proposed linear unconditionally stable algorithms of Simo and Armero (1993), yields a method for solution of the incompressible Navier-Stokes equations ideal for either diffusive or advection-dominated flows. Examples from scalar advection-diffusion and the solution of the incompressible Navier-Stokes equations are presented.

    Modelling flow over a backward-facing step using the F.E.M. and the two-equation model of turbulence (1981)

    Notes: Flow over a downstream-facing step is predicted using the F.E.M. A two-equation model of turbulence is employed where the transport of turbulence kinetic energy and dissipation rate are depicted using transport-type equations, i.e. the two-equation model of turbulence. The results obtained are compared with other models and experimental results. Generally, the model was found to be under-predictive with regard to the reattachment length when previous empirical data was used in the transport equations.

    Notes: Heat transfer associated with forced convection between bundles of cylindrical fuel rods is analysed using the finite element method. A subchannel technique is employed and the numerical results are compared with previous experimental and numerical values. The solid and fluid zones are analysed, for temperature distribution, as a single domain.
