Lehnen, Louisa Nitsch, Sven Poli, Christian Riedel, Steffen Tiedt, Sarah Zweynert, Gabor C. Petzold, Franziska Dorn, Felix J. Bode, on behalf of the GSR-ET investigators

Publikováno v: Neurological Research and Practice, Vol 6, Iss 1, Pp 1-7 (2024)

Abstract Background Endovascular treatment (ET) options for acute stroke due to distal middle cerebral artery occlusions are rapidly evolving, but data on outcome and safety are sparse. We therefore performed an analysis of patients undergoing ET for

Journal of Stroke and Cerebrovascular Diseases

Objectives Vaccine-induced thrombotic thrombocytopenia (VITT) is a rare complication after adenoviral vector vaccination against COVID-19 reported up to 24 days after ChAdOx1 nCOV-19 (AZD1222) vaccination. This report describes a case with a signific

Fibroblast growth factor receptor 1 gene amplification in gastric adenocarcinoma

Autor: Nils C. Lehnen, Sven Perner, Glen Kristiansen, Manuel H. Schäfer, Tobias Höller, Philipp Lingohr, Anke Sträßer, Ines Gütgemann, Jörg C. Kalff, Martin Braun

Publikováno v: Human Pathology. 46:1488-1495

Gastric adenocarcinomas are associated with a poor prognosis due to the fact that the tumor has often metastasized by the time of diagnosis. Thus, identification of novel therapeutic targets is highly desirable. Here, we examined gene copy number of

Publikováno v: Histopathology. 63(2)

Aims Pancreatic ductal adenocarcinomas (PDACs) are chemoresistant, resulting in extremely poor survival of patients; therefore, novel molecular targets, even in small subsets of genetically characterized tumours, are urgently needed. Tyrosine kinase
