Helmut Tauchmann – 80 Jahre

Arno Kuhlig zum Gedenken
(2009)
Arno Kuhlig verstarb am 30.09.2008 im Alter von 78 Jahren in Bitterfeld. Die Nachricht von seinem Tod kam für uns alle überraschend. Arno Kuhlig wurde am 07.04.1930 in Bitterfeld geboren. Er besuchte bis 1944 die Volksschule, lernte danach Betriebsschlosser und Isolierklempner und war 25 Jahre bei einer Montagefirma tätig. Anschließend arbeitete er in seinem Beruf im damaligen Chemiekombinat Bitterfeld. Im April 1987 musste er plötzlich wegen einer schweren Krankheit aus dem Berufsleben ausscheiden. Arno Kuhlig gehörte 1949 mit zu den Gründern der heutigen „NABU Fachgruppe Ornithologie und Naturschutz Bitterfeld-Wolfen“ und war von 1979 bis 2005 ihr Vorsitzender.
Nachruf für Wolfram Weiner
(2013)
Am 24. September 2011 verstarb für uns alle unerwartet Wolfram Weiner im Alter von 69 Jahren in Wolfen. Geboren wurde er am 13.08.1942 in Brandis bei Leipzig. In den Jahren von 1963 bis 1991 war Wolfram eines der aktivsten Mitglieder in der Fachgruppe "Ornithologie und Naturschutz Bitterfeld" des Kulturbundes. Viele organisatorische und praktische Arbeiten liefen unter seiner Anleitung. Besonders intensiv beschäftigte er sich mit Greifvögeln und Eulen.
It is now accepted that heart failure (HF) is a complex multifunctional disease rather than simply a hemodynamic dysfunction. Despite its complexity, stressed cardiomyocytes often follow conserved patterns of structural remodelling in order to adapt, survive, and regenerate. When cardiac adaptations cannot cope with mechanical, ischemic, and metabolic loads efficiently or become chronically activated, as, for example, after infection, then the ongoing structural remodelling and dedifferentiation often lead to compromised pump function and patient death. It is, therefore, of major importance to understand key events in the progression from a compensatory left ventricular (LV) systolic dysfunction to a decompensatory LV systolic dysfunction and HF. To achieve this, various animal models in combination with an “omics” toolbox can be used. These approaches will ultimately lead to the identification of an arsenal of biomarkers and therapeutic targets which have the potential to shape the medicine of the future.
BACKGROUND: Polyclonal anti-thymocyte globulins (ATGs) are immunosuppressive drugs widely used in induction of immunosuppression and treatment of acute rejection after solid organ transplantation. We have previously demonstrated that ATGs bind to endothelial cells in vitro, and are able to modulate ECs. The aim of this study was to investigate the binding of ATGs to endothelial cells under in vivo conditions.
MATERIAL AND METHODS: Muscle biopsies from extremities of cynomolgus monkeys were obtained after ischemia/reperfusion at 4°C. ATGs (Thymoglobulin, Sanofi-Aventis, France; 1 mg/kg) were added to the blood 30 min prior to the reperfusion. Biopsies (n=10) of patients undergoing heart transplantation and preoperatively treated with ATGs (Thymoglobulin, Sanofi-Aventis, France; 1.5 mg/kg) as induction therapy were also analyzed 6 hours and 7 days after induction. Binding of ATGs to ECs was analyzed with an anti-rabbit IgG antibody by means of immunohistochemistry.
RESULTS: Binding of ATGs to endothelial cells could be demonstrated in vivo in our animal experiments 4 hours after reperfusion, as well as in the clinical biopsies 6 hours after induction of immunosuppression in heart transplant patients, showing a preferred localization in post-capillary veins. No expression of ATGs on the endothelial surface could be observed after 7 days, suggesting that ATGs may be washed out from the endothelial surface in a time-dependent manner.
CONCLUSIONS: Our results show that ATGs are able to bind to endothelial cells in an experimental model and in clinical practice, supporting preconditioning strategies with ATGs in solid organ transplantation.
