The selection of suitable variables is the first and important issue for fish habitat requirements and stream/river management programs. Classification trees (CTs) were used to study habitat preferences of the roach (Rutilus rutilus) in the Flemish stream basins (Belgium). The presence/absence of the roach was modeled based on a set of physicochemical and(More)
The production and growth regulatory activity of transforming growth factor beta were studied in human thyroid tissue. As estimated by its mRNA expression in fresh tissue samples, transforming growth factor beta was produced in normal and in diseased thyroid glands. Transforming growth factor beta mRNA was mainly produced by thyroid follicular cells and in(More)
In this study we have compared the effects of granulocyte macrophage colony stimulating factor (GM-CSF) on purified normal blood monocytes, with two other haemopoietic growth factors, Interleukin (IL-) 3 and Macrophage (M-)CSF on HLA class I, class II and intercellular adhesion molecule 1 (ICAM-1) expression in the presence and absence of dexamethasone(More)
Peripheral blood monocytes from up to 13 normal donors were stimulated with the cytokines interferon gamma (IFN-gamma), interleukin 4 (IL-4) and granulocyte macrophage-colony stimulating factor (GM-CSF) in the presence or absence of dexamethasone (Dex), and the effects on HLA class II (HLA-DR, DP and DQ) expression studied. Dex markedly augmented HLA-DR, DP(More)
Predicting and modeling of habitat preferences of fish is a very important issue for aquatic management. Classification trees (CTs) were used to predict the habitat preferences of the Caspian kutum (Rutilus frisii kutum, hereafter kutum) in the southern Caspian Sea. The applied model was optimized with genetic algorithm (GA) and greedy stepwise (GS) to(More)
In the present study, the data-driven (classification trees and support vector machines) and multivariate techniques (principal component analysis and discriminant analysis) were applied to study the habitat preferences of an invasive aquatic fern (Azolla filiculoides) in the Selkeh Wildlife Refuge (a protected area in Anzali wetland, northern Iran). The(More)
