Comparison of dietary oils with different polyunsaturated fatty acid n-3 and n-6 content in the rat model of cutaneous wound healing
(MDPI, 2020-10-24)Dietary supplementation with polyunsaturated fatty acids (PUFA) n-3 can affect cutaneous wound healing; however, recent findings demonstrate the variable extent of their influence on the quality of healing. Here, we compare ... -
The effect of synthesis procedure on hydrogen peroxidase-like catalytic activity of iron oxide magnetic particles
(MDPI, 2020-09-27)A comparative study was carried out using magnetic nanoparticles (MNPs) for the fabrication of non-enzymatic sensors for the continuous and rapid detection and monitoring of H2O2. Various MNPs, differing in terms of their ... -
Molecularly imprinted polymers coupled to mass spectrometric detection for metallothionein sensing
(Elsevier, 2019-06-01)We report a facile method for detection of metallothionein (MT), a promising clinically relevant biomarker, in spiked plasma samples. This method, for the first time, integrates molecularly imprinted polymers as ... -
Hydroxyproline assay by HPLC-FLD applied for wound healing determination in rat model
(Mendel University in Brno, 2019-12-31)In this work, we focused on four types of oils and their response on wound healing of the skin of rats after dietary exposure. A set of samples consisted of 48 adult male rats of Wistar albino, which were divided into four ... -
Love Wave Sensors with Silver Modified Polypyrrole Nanoparticles for VOCs Monitoring
(MDPI, 2020-03-06)Love wave sensors with silver-modified polypyrrole nanoparticles are developed in this work. These systems prove functional at room temperature with enhanced response, sensitivity and response time, as compared to other ... -
Metallothionein Isoforms as Double Agents - Their Roles in Carcinogenesis, Cancer Progression and Chemoresistance
(Elsevier, 2020-09-30)Metallothioneins (MTs) are small cysteine-rich intracellular proteins with four major isoforms identified in mammals, designated MT-1 through MT-4. The best known biological functions of MTs are their ability to bind and ... -
Mass Spectrometry-Based Structural Analysis of Cysteine-Rich Metal-Binding Sites in Proteins with MetaOdysseus R Software
Identification of metal-binding sites in proteins and understanding metalcoupled protein folding mechanisms are aspects of high importance for the structure-tofunction relationship. Mass spectrometry (MS) has brought a ... -
