چکیده
The aim of the study was to give an overview of the mechanism of inhibition of Na/K–ATPase and Mg–ATPase activity, the enzymes playing a key role in the active transport of monovalent cations (Na and K) across the cell membrane, induced by the ions of some transition (Cu, Zn, Fe, Co) and heavy (Hg i Cd) metals, ammonium decavanadate and noble metals complexes ([PtCl2DMSO2], [AuCl4], [PdCl4], [PdCl(dien)], [PdCl(Me4dien)]). The extensive kinetic analysis was done in order to determine kinetic parameters and the mode of interaction of Na/K–ATPase and Mg–ATPase and the investigated compounds. In addition, the ability of sulphur-donor ligands (L-cysteine and glutathione), as well as EDTA, to prevent metal ions and complexes induced inhibition of Na/K–ATPase activity and to recover enzymatic activity was investigated. Finally, development of highly sensitive and selective analytical tools on the basis of the immobilized enzyme is discussed in this paper.

Extended Time of Cold Ischemia and Its Influence on the Physiological Function of Human Adult Pancreatic Islets
In this study we compared the effects of duration of cold ischemia (longer and shorter ischemia) on the yield, viability and preservation of the physiological function and insulin secretion of adult human pancreatic islets in short-term (seven days) culture. Based on the tested parameters, we established that there are no major differences between these two test groups and that the storage and ...

Identification of Nonlinear Models with Feedforward Neural Network and Digital Recurrent Network
Nonlinear system identification via Feedforward Neural Networks (FNN) and Digital Recurrent Network (DRN) is studied in this paper. The standard backpropagation algorithm is used to train the FNN. A dynamic backpropagation algorithm is employed to adapt weights and biases of the DRN. The neural networks are trained using the identified error between the model’s output and plant’s output.
