Amperometric Sensor for Detection of Chloride Ions
Chloride ion sensing is important in many fields such as clinical diagnosis, environmental monitoring and industrial applications. We have measured chloride ions at a carbon paste electrode (CPE) and at a CPE modified with ...
Flow Injection Analysis Coupled with Carbon Electrodes as the Tool for Analysis of Naphthoquinones with Respect to Their Content and Functions in Biological Samples
Naphthoquinones are one of the groups of secondary metabolites widespread in nature, where they mostly appear as chromatic pigments. They embody broad-range of biological actions from phytotoxic to fungicidal. An anticancer ...
An Investigation of Glutathione-Platinum(II) Interactions by Means of the Flow Injection Analysis Using Glassy Carbon Electrode
Glutathione was discovered by M. J. de Rey Pailhade at the end of the 19th century as the substance (hydrogénant le soufre), which was renamed by F.G. Hopkins in 1921. Hopkins first characterised the compound as a dipeptide ...
Study of Interactions between Metallothionein and Cisplatin by using Differential Pulse Voltammetry Brdicka's reaction and Quartz Crystal Microbalance
Treatment strategies for tumour diseases are progressively focusing on personalization of medicine. However, this focus requires methods revealing the early general biological mechanisms, including the formation anti-cancer ...
Úvaha o vzdělávání v oblasti ochrany obyvatelstva z pohledu nejen historického
(FTK UP, 2008-05-06)
Změny ve společnosti se po změně systému nevyhnuly ani skladbě předmětů na školách. Je známo, že čím je sofistikovanější společnost, tím je zranitelnější a náchylnější ke kolapsu. V příspěvku předkládáme několik poznatků ...
Stability of collagen scaffold implants for animals with iatrogenic articular cartilage defoects
(University of Veterinary and Pharmaceutical Sciences in Brno, 2009-12-15)
Synthesis and characterization of biodegradable hydrogels based on collagen modified by addition of synthetic biodegradable copolymer intended for preparation of porous scaffolds for mesenchymal stem cells used for possible ...
Fluoride Anion Binding by Natural Lignite (South Moravian Deposit of Vienna Basin)
Natural lignite from South Moravia was tested for the sorption of fluoride anion in concentration range from 0.05 to 0.8 mmol/l. The lignite removes majority of fluorides and only about 13% of sorption is reversible upon ...
Aggregation behavior of novel hyaluronan derivatives-a fluorescence probe study
Aggregation properties of hydrophobized hyaluronan (hHA) in different molecular weights and degree of substitution were studied by pyrene and perylene fluorescence method. The critical aggregation concentration (cac) was ...
Detailed balance in reaction kinetics - consequence of mass conservation?
Detailed balance condition for triangular isomerisation mechanism is derived from the more general permanence of atoms, consequently, it should be viewed as a special equilibrium result of mass conservation.
Current-Mode Circuits Based on SIMO OTA: Review and New Applications in Filters
The paper deals with design of low-order RC filters working in current mode (CM). As the basic building blocks, transconductors (OTA) with single input and multiple outputs are used. One-loop, two-loop and multi-loop ...
