The anti-malarial artesunate also exerts profound anti-cancer activity. The susceptibility of tumor cells to artesunate can be enhanced by ferrous iron. The transferrin receptor (TfR) is involved in iron uptake by internalization of transferrin and is over-expressed in rapidly growing tumors. The ATP-binding cassette (ABC) transporters ABCB6 and ABCB7 are… (More)
High-risk human papillomavirus (hrHPV)-DNA testing is frequently performed parallel to cytology for the detection of high-grade dysplasia and cervical cancer particularly in women above 30 years of age. Although highly sensitive, hrHPV testing cannot distinguish between HPV-positive women with or without clinically relevant lesions. However, in principle… (More)
Pituitary-adrenal activity has been found to be inhibited during early nocturnal sleep in humans. This inhibition was supposed to reflect a regulatory influence of hippocampal cells characterized by the expression of mineralocorticoid receptors (MR). Pituitary adrenal responsiveness to bolus injections of CRH (50 micrograms) was examined in each of nine… (More)
Upper tract urothelial carcinomas in the proximal ureter are an uncommon disease. We present a case in which it was firstly detected by fluorescence in situ hybridization and not by endoscopy and radiologic imaging. Consequently, a radical nephroureterectomy with excision of the bladder cuff was performed as the gold standard treatment.
