OBJECTIVES To analyse circulating concentrations of advanced glycation end products (AGEs) in patients with severe congestive heart failure (CHF) and after heart transplantation; to identify the potential contribution of kidney function to plasma AGE concentrations; and to determine whether AGE concentrations and parameters of oxidative stress are(More)
Three synthetic inhibitors of proteases (tosyl lysine chloromethyl ketone, tosyl phenylalanine chloromethyl ketone, and tosyl arginine methyl ester) inhibit the tumorigenesis initiated in mouse skin by 7,12-dimethylbenz(a)anthracene and promoted by croton oil or its active principle, phorbol ester. These protease inhibitors, when applied directly to mouse(More)
The effect of experimentally induced acute renal failure (ARF) on neuronal cell activation was investigated by immunohistochemistry for Fos and Fra-2 in the rat brain. ARF in rats was induced by bilateral nephrectomy (BNX), bilateral ureter ligature (BUL) and uranyl acetate injection with proper controls (sham-operation or saline injections, respectively).(More)
High levels of various uremic toxins such as guanidino compounds and advanced glycation endproducts, as well as an excess of parathyroid hormones, are involved in the pathogenesis of acute uremic encephalopathy. Moreover, distant effects of the damaged kidney with enhanced production of inflammatory mediators are implicated. Data on the pump activity of an(More)
Application of electricity for pain treatment dates back to thousands of years BC. The Ancient Egyptians and later the Greeks and Romans recognized that electrical fishes are capable of generating electric shocks for relief of pain. In the 18th and 19th centuries these natural producers of electricity were replaced by man-made electrical devices. This(More)
BACKGROUND Patients with end-stage renal failure, whether on conservative or haemodialysis therapy, have a high incidence of DNA damage. It is not known if improved control of the uraemic state by daily haemodialysis (DHD) reduces DNA lesions. METHODS DNA damage in peripheral blood lymphocytes (PBLs) was evaluated in a cross-sectional study of 13 patients(More)
BACKGROUND AND OBJECTIVE In end-stage renal failure the incidence of cancer is increased. With regard to frequency and pattern of distribution of the tumors, there are substantial regional differences. Since this topic has to date received only minimal attention in Germany, we undertook a multi-centric analysis (8 dialysis centres) in North Bavaria in order(More)
At the beginning of the 19th century, medicine was based largely on speculative and philosophical concepts. The greatest merit of Rudolf Virchow was without doubt a way of thinking based on natural science. In place of the empirical chaos represented by the doctrines of humors and crasis, he created the new paradigm of cellular pathology. In the field of(More)
Excess body weight may be associated with various functional/structural lesions of the kidney. The spectrum ranges from glomerulomegaly with or without focal or segmental glomerulosclerosis, to diabetic nephropathy, to carcinoma of the kidney and nephrolithiasis. The first sign of renal injury is microalbuminuria or frank proteinuria, in particular in the(More)
