Gut microbiota and immune profiling of microbiota-humanised versus wildtype mouse models of hepatointestinal schistosomiasis

Autor: K. A. Stark, G. Rinaldi, A. Costain, S. Clare, C. Tolley, A. Almeida, C. McCarthy, K. Harcourt, C. Brandt, T. D. Lawley, M. Berriman, A. S. MacDonald, J. E. Forde-Thomas, B. J. Hulme, K. F. Hoffmann, C. Cantacessi, A. Cortés

Publikováno v: Animal Microbiome, Vol 6, Iss 1, Pp 1-19 (2024)

Abstract Mounting evidence of the occurrence of direct and indirect interactions between the human blood fluke, Schistosoma mansoni, and the gut microbiota of rodent models raises questions on the potential role(s) of the latter in the pathophysiolog

Pulmonary inflammation promoted by type-2 dendritic cells is a feature of human and murine schistosomiasis

Autor: E. L. Houlder, A. H. Costain, I. Nambuya, S. L. Brown, J. P. R. Koopman, M. C. C. Langenberg, J. J. Janse, M. A. Hoogerwerf, A. J. L. Ridley, J. E. Forde-Thomas, S. A. P. Colombo, B. M. F. Winkel, A. A. Galdon, K. F. Hoffmann, P. C. Cook, M. Roestenberg, H. Mpairwe, A. S. MacDonald

Publikováno v: Nature Communications, Vol 14, Iss 1, Pp 1-12 (2023)

Schistosomiasis, a parasitic helminth infection, causes pulmonary symptoms during acute and chronic infection. Here, Houlder et al characterise the pulmonary immune response and demonstrate the role type 2 dendritic cells play in lung inflammation.

Influence of an Electrically Non-Conducting Heat Sink for Power Semiconductors on Radiated Interferences

Autor: S. Chromy, K. Rathjen, S. Fahlbusch, K. F. Hoffmann, S. Dickmann

Publikováno v: Advances in Radio Science, Vol 16, Pp 117-122 (2018)

Power semiconductors are used in a growing number of applications. Furthermore, faster switching transients and therefore higher switching frequencies can be realised. This leads to higher radiated interferences at higher frequencies. In power ele

Numerical modeling for heatsink emissions in power electronics

Autor: J. Kulanayagam, J. H. Hagmann, S. Schenke, K. F. Hoffmann, S. Dickmann

Publikováno v: Advances in Radio Science, Vol 10, Pp 239-243 (2012)

The parasitic coupling between power semiconductors and the heat sink is responsible for noise current in Switching Mode Power Supply (SMPS) systems. In this paper, the variations in the radiation characteristics of heatsinks are investigated with re

Reduction of heat sink common-mode currents in switching mode power supply circuits

Autor: J. Kulanayagam, J. H. Hagmann, K. F. Hoffmann, S. Dickmann

Publikováno v: Advances in Radio Science, Vol 9, Pp 317-321 (2011)

In this paper, a new filter design for a heat sink is presented. The parasitic couplings between electric power devices and the heat sink are responsible for common-mode currents. The main focus is on the reduction of these currents to reduce the hea
