In this article we review the value and utility of the minipig as an animal model in regulatory toxicity testing. Our review is based on detailed consideration of the comparative biology of the minipig, and of the practical features of toxicity testing in the minipig. The minipig presents a favourable profile as a non-rodent toxicology model, in terms of(More)
Inhibitors of phosphodiesterase type 4 (PDE4) are currently exploited as potent drugs for pulmonary diseases. Some PDE4 inhibitors induce necrotizing panarteritis in the mesentery of rats, comparable to spontaneous polyarteritis nodosa in rats and vascular alterations that are induced by various vasoactive compounds, such as fenoldopam and inhibitors of(More)
The objective of the RETHINK project was to evaluate the potential impact of toxicity testing in the minipig as an alternative approach in regulatory toxicity testing that can contribute to the replacement, refinement and reduction of animal testing (3Rs). Expert study groups (Working Groups) were assembled to review five different areas relating to the use(More)
The objective of the RETHINK project was to evaluate the potential impact of toxicity testing in the minipig as an alternative approach in regulatory toxicity testing that can contribute to the replacement, refinement and reduction of animal testing (3Rs). Minipigs are strains of domestic pigs that are markedly smaller than farmyard varieties, and thus(More)
The aim of this study was to better characterize rabbit proximal kidney tubule cells cultured on collagen IV-coated porous inserts, as compared to the same cells seeded in standard plastic wells. Total protein contents in confluent monolayers on permeable membranes were about twofold higher than those measured in confluent cultures in plastic wells.(More)
In the ILSI Human Toxicity Program, human toxicity was identified with 94% in studies of 1 month or less duration. Safety pharmacology studies and 1 month toxicity studies are prerequisites of INDs. These studies contributed in 69% to the predictivity of human toxicity. Correlating data from pharmacology and toxicology data will therefore enhance the(More)
The properties of the LLC-RK1 cell line (derived from new-born rabbit kidney) commonly used as a model of proximal tubular cells are described. First, morphological, biochemical and functional approaches were used to study the expression of differentiated properties of the cell line. In a second part, the ability of this cell line to predict nephrotoxicity(More)
A 69-year-old male suffering from progressive dementia died 3 years after the beginning of his disease. The neuropathology of this case revealed the coexistence of senile changes, typical for Alzheimer's disease, and the characteristics of Parkinson's disease, namely, numerous senile plaques and neurofibrillary tangles in the cerebrum and neuronal loss with(More)
In this paper, changes in serum levels of the cardiac biomarkers troponin I and the heart-type fatty acid-binding protein (H-FABP) following administration of a long-acting beta(2)-sympathicomimeticum (long-acting beta-agonist, LABA) to dogs were measured. We measured troponin I in dogs in a 4-week repeated-dose study with inhalative administration of(More)
Fast 20 Jahre nach der ersten Anwendung autologer Knorpelzellen im Rahmen einer autologen Knorpelzelltransplantation (ACT) am Menschen hat sich diese Methode als hochwertiges und gut untersuchtes Verfahren zur Behandlung von Knorpelschäden am Kniegelenk etabliert. Mittlerweile liegen sowohl Langzeitergebnisse als auch prospektiv-randomisierte Studien (RCT)(More)
