During the past ten years, coupled quantum wells have emerged as a promising system for experiments on Bose condensation of excitons, with numerous theoretical and experimental studies aimed at the demonstration of this effect. One of the issues driving these studies is the possibility of long-range coherent transport of excitons. Excitons in quantum wells(More)
The objective of this study was to assess cytotoxic effects of ochratoxin A (OTA), penicillic acid (PA), citrinin (CIT), fumonisin B1 (FB1) and their combinations (as naturally occur in real practice) on human peripheral blood mononuclear cells (PBM) using a simple and cheap " in vitro " cytotoxicity test as MTT assay. A stronger suppression on metabolic(More)
A survey was made of the literature concerning the occurrence and incidence of mycotoxic nephropathy in pigs and chicks in different countries. Various etiological factors contributing to the development of the disease were considered. The main nephrotoxic fungi as well as the specific conditions for their growth and toxins production were briefly(More)
