Ion exchange chromatography and mass spectrometric methods for analysis of cadmium-phytochelatin (II) complexes
(MDPI, 2013-03-28)In this study, in vitro formed Cd-phytochelatin (PC2) complexes were characterized using ion exchange chromatography (IEC) and matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry. The ... -
Effect of Magnetic Nanoparticles on Tobacco BY-2 Cell Suspension Culture
(MDPI, 2013-01-01)Nanomaterials are structures whose exceptionality is based on their large surface, which is closely connected with reactivity and modification possibilities. Due to these properties nanomaterials are used in textile industry ... -
Quantum Dots - Characterization, Preparation and Usage in Biological Systems
(MDPI, 2009-02-20)The use of fluorescent nanoparticles as probes for bioanalytical applications is a highly promising technique because fluorescence-based techniques are very sensitive. Quantum dots (QDs) seem to show the greatest promise ... -
Flow Injection Analysis Coupled with Carbon Electrodes as the Tool for Analysis of Naphthoquinones with Respect to Their Content and Functions in Biological Samples
(MDPI, 2006-10-01)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
(MDPI, 2007-07-20)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
(MDPI, 2009-03-15)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 ... -
Sarcosine as a potential prostate cancer biomarker – A review
(MDPI, 2013-07-04)Prostate cancer (CaP) is the most common type of tumour disease in men. Early diagnosis of cancer of the prostate is very important, because the sooner the cancer is detected, the better it is treated. According to that ... -
Serum metallothioneins in childhood tumours – A potential prognostic marker
(MDPI, 2013-06-06)Metallothioneins (MT) are low molecular weight, cysteine-rich proteins maintaining metal ions homeostasis. They play a role in carcinogenesis and may also cause chemoresistance. The aim of the study was to explore the ... -
Utilizing of square wave voltammetry to detect flavonoids in the presence of human urine
(MDPI, 2007-10-15)About biological affecting of flavonoids on animal organisms is known less, thus we selected flavonoids, flavanones and flavones, and their glycosides, which were examined as potential inducers of cytochrome(s) P450 when ... -
Shapes of Differential Pulse Voltammograms and Level of Metallothionein at Different Animal Species
(MDPI, 2007-10-19)Metallothioneins play a key role in maintaining homeostasis of essential metals and in protecting of cells against metal toxicity as well as oxidative damaging. Excepting humans, blood levels of metallothionein have not ... -
