We investigated the effects of ethyl pyruvate (EP) on oxidative and endoplasmic reticulum (ER) stress due to experimental testicular ischemia-reperfusion (I-R). Eighteen rats were divided into a control group, torsion-detorsion (T-D) group an EP group. For pretreatment 50 mg/kg was given intraperitoneally (i.p.) 30 min before detorsion. Tissue 4-hydroxynonenal (4-HNE) 78-kDa glucose-regulated protein (GRP78) levels determined using enzyme-linked immunosorbent assay (ELISA) kits. total...

Introduction: Lymphoepithelioma-like carcinoma of the bladder (LELC-B) is a rare variant tumors and until today only 145 cases are reported in literature. It has worse prognosis survival rates comparison with papillary muscle invasive tumors. However, general treatment options including radical cystectomy, chemotherapy radiotherapy; discovery programmed death cell ligand-1 (PDL-1) expression for LELC-B recently, may lead novel immunohistochemical diagnostic method PDL-1 immunostaining...

Phylloidestumoren (PT) stellen eine seltene Erkrankungsgruppe der Mamma dar, mit einer Prävalenz von 0,5% aller Mammakarzinome. PT sind fibroepitheliale Tumoren epithelialen und mesothelialen Metaplasien. Das Malignitätspotenzial liegt bei 16% für Borderline 9% maligne PT. Aufgrund zungenförmigen Ausläufern ist nach operativer Therapie die Lokalrezidivrate 10 – 30% relativ hoch, das Risiko Fernmetastasierung < 10% eher gering.

Zielsetzung CX3CL1 ist ein multifunktionales Chemokin, das in einer Vielzahl von biologischen Prozessen beteiligt ist. Es spielt bei der Rekrutierung Immunzellen den Tumor eine Rolle, unterstützt aber auch die Tumorprogression. Daher war Ziel dieser Studie, Einfluss Überexpression beim HER2-positiven Mammakarzinom in-vitro und im Humanisierten Tumormaus Modell (HTM) zu untersuchen.
