Effect of Ampicillin, Streptomycin, Penicillin and Tetracycline on Metal Resistant and Non-Resistant Staphylococcus aureus
(MDPI AG, POSTFACH, 2014-03-19)
There is an arising and concerning issue in the field of bacterial resistance, which is confirmed by the number of deaths associated with drug-resistant bacterial infections. The aim of this study was to compare the effects ...
Multi-instrumental Analysis of Tissues of Sunflower Plants Treated with Silver(I) Ions - Plants as Bioindicators of Environmental Pollution
(MDPI, 2008-01-24)
The aim of this work is to investigate sunflower plants response on stress induced by silver(I) ions. The sunflower plants were exposed to silver(I) ions (0, 0.1, 0.5, and 1 mM) for 96 h. Primarily we aimed our attention ...
New Hydrodynamic Electrochemical Arrangement for Cadmium Ions Detection Using Thick-Film Chemical Sensor Electrodes
(MDPI, 2006-11-06)
Miniaturization and integration of chemical devices into modules that are dimensionally comparable with electronic chips (Lab on Chip) is nowadays developing worldwide. The aim of our work was to suggest and optimize the ...

(MDPI, 2015-05-31)
V této práci jsme se zaměřili na rozdíly mezi bakteriálních kultur E. coli, získaných ze stěrů infekčních ran pacientů ve srovnání s laboratorním E. coli. Navíc blokování proteinu odpovědné za syntézu glutathion ...
Modification of working electrode surface with carbon nanotubes as an electrochemical sensor for estimation of melting points of DNA
(Elsevier BV, 2009-09-06)
Screen-printed with three electrode system was used in this study. A working electrode has been printed from carbon nanotubes based paste on silver layer modified with nano-patterned structures for the first case. In the ...
Electrochemical Microsensors for the Detection of Cadmium(II) and Lead(II) Ions in Plants
(MDPI, 2010-06-01)
Routine determination of trace metals in complex media is still a difficult task for many analytical instruments. The aim of this work was to compare three electro-chemical instruments [a standard potentiostat (Autolab), ...
Staphylococcus aureus and MRSA Growth and Biofilm Formation after Treatment with Antibiotics and SeNPs
(MDPI, 2015-10-16)
Methicillin-resistant Staphylococcus aureus (MRSA) is a dangerous pathogen resistant to -lactam antibiotics. Due to its resistance, it is difficult to manage the infections caused by this strain. We examined this issue in ...
