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 ...
A 3D Microfluidic Chip for Electrochemical Detection of Hydrolysed Nucleic Bases by a Modified Glassy Carbon Electrode
(MDPI AG, POSTFACH, CH-4005 BASEL, SWITZERLAND, 2015-02-01)
Modification of carbon materials, especially graphene-based materials, has wide applications in electrochemical detection such as electrochemical lab-on-chip devices. A glassy carbon electrode (GCE) modified with chemically ...
Study of Linkage between Glutathione Pathway and the Antibiotic Resistance of Escherichia coli from Patients’ Swabs
(MDPI, 2015-05-31)
In this work, we focused on the differences between bacterial cultures of E. coli obtained from swabs of infectious wounds of patients compared to laboratory E. coli. In addition, blocking of the protein responsible for ...
Exposure to 17 beta-Oestradiol Induces Oxidative Stress in the Non-Oestrogen Receptor Invertebrate Species Eisenia fetida
(PLOS, 2015-12-22)
Background
The environmental impacts of various substances on all levels of organisms are under investigation. Among these substances, endocrine-disrupting compounds (EDCs) present a threat, although the environmental ...
Effects of stratospheric conditions on viability, metabolism and proteome of prokaryotic cells
(MDPI, 2015-09-09)
The application of ultraviolet (UV) radiation to inhibit bacterial growth is based on the principle that the exposure of DNA to UV radiation results in the formation of cytotoxic lesions, leading to inactivation of ...
Papillomavirus infection of roe deer in the Czech Republic and fibropapilloma-associated levels of metallothionein, zinc, and oxidative stress
(University of Veterinary and Pharmaceutical Sciences, 2015-06-01)
The present study aimed at the aetiological diagnosis of skin tumours of roe deer (Capreolus capreolus) in the Czech Republic. A total of 33 roe deer specimens showing skin masses were sampled for histopathology, virus ...
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 ...
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 ...
Apoferritin as a ubiquitous nanocarrier with excellent shelf life
(Dove Medical Press, 2017-07-11)
Due to many adverse effects of conventional chemotherapy, novel methods of targeting drugs to cancer cells are being investigated. Nanosize carriers are a suitable platform for this specific delivery. Herein, we evaluated ...
The Application of Curve Fitting on the Voltammograms of Various Isoforms of Metallothioneins–Metal Complexes
(MDPI, 2017-03-01)
The translation of metallothioneins (MTs) is one of the defense strategies by which
organisms protect themselves from metal-induced toxicity. MTs belong to a family of proteins
comprising MT-1, MT-2, MT-3, and MT-4 classes, ...
