In vitro evaluation of the immunomodulatory and anticarcinogenic activity of the freshwater bryozoan hyalinella punctata methanolic extract
(Inst Materials Physics, 2012)
The immunomodulatory and anticarcinogenic activity of the freshwater bryozoan Hyalinella punctata methanolic extract (MEx) was evaluated in vitro on selected biosystems for the first time. Murine lymphocytes and macrophages ...
Antimicrobial activity of the freshwater bryozoan hyalinella punctata (Hancock, 1850)
(Inst Materials Physics, 2012)
The antimicrobial activity of the freshwater bryozoan Hyalinella punctata (Hancock, 1850) was tested by microdilution method against eight bacteria and eight fungi for the first time. All five crude extracts (hexane, ...
ZnO based transparent conductive oxide films with controlled type of conduction
(Elsevier Science Sa, Lausanne, 2014)
The transparent conductive oxide films with controlled type of conduction are of great importance and their preparation is intensively studied. In our work, the preparation of such films based on doped ZnO was realized in ...
Decomposition of Complex Fluorescence Spectra Containing Components with Close Emission Maxima Positions and Similar Quantum Yields. Application to Fluorescence Spectra of Proteins
(Springer/Plenum Publishers, New York, 2013)
Despite of widely application of multivariate analysis in chemometrics, problem of resolving closely positioned components in the fluorescence spectra remained unsolved, thus limiting the usage of fluorescence spectroscopy ...
Review of sterlet (Acipenser ruthenus L. 1758) (Actinopterygii: Acipenseridae) feeding habits in the River Danube, 1694-852 river km
(Taylor & Francis Ltd, Abingdon, 2015)
The aim of this work is to present the variation in the sterlet's (Acipenser ruthenus L. 1758) diet along the course of the River Danube, from 1694 to 852 river km. The diet of sterlet mostly comprised 12 bottom fauna taxa. ...
Evaluation of procedures for assessing anti- and pro-oxidants in plant samples
(Royal Soc Chemistry, Cambridge, 2016)
Plants as well as other aerobic organisms constantly produce reactive oxygen species (ROS). At regulated low concentrations ROS may serve as signal molecules, while in excessive amounts these may cause oxidative damage to ...
Common barbel (Barbus barbus) as a bioindicator of surface river sediment pollution with Cu and Zn in three rivers of the Danube River Basin in Serbia
(Springer Heidelberg, Heidelberg, 2016)
River sediments are a major source of metal contamination in aquatic food webs. Due to the ability of metals to move up the food chain, fishes, occupying higher trophic levels, are considered to be good environmental ...
Cell Death Parameters as Revealed by Whole-Cell Patch-Clamp and Interval Weighted Spectra Averaging: Changes in Membrane Properties and Current Frequency of Cultured Mouse Microglial Cells Induced by Glutaraldehyde
(Springer, New York, 2015)
The physiological and biochemical factors that lead to cell death have not been recognized completely. To our knowledge, there are no data on the bioelectric parameters that characterize early period of cell death, as well ...
Nonlinear properties of antimony-doped BaTiO3 ceramics
(Springer Heidelberg, Heidelberg, 2015)
Barium titanate nanopowders doped with various concentrations of antimony were synthesized by polymeric precursors method based on modified Pechini process. Obtained powders were pressed and sintered at 1,573 K for 8 h. ...
Characterisation of antioxidants in photosynthetic and non-photosynthetic leaf tissues of variegated Pelargonium zonale plants
(Wiley, Hoboken, 2016)
Hydrogen peroxide is an important signalling molecule, involved in regulation of numerous metabolic processes in plants. The most important sources of H2O2 in photosynthetically active cells are chloroplasts and peroxisomes. ...
