Electrochemical DNA/screen-printed electrode biosensor (DNA/SPE biosensor) was tested for the detection of alterations in DNA formed as a consequence of the reaction between DNA and oxidative products of fatty acids. Interaction of DNA with a mixture of products generated during the oxidation of linoleic and oleic acids manifested DNA damage depending on a tested fatty acid and the presence of hydroperoxides and thiobarbituric acid reactive substances (TBARS) determined after the oxidation of fatty acids. A bigger extent of the DNA damage was registered in the case of the interaction with oxidized linoleic acid with the high content of TBARS. The results achieved suggest the possible application of DNA/SPE biosensor in the detection of an interaction between DNA and products of fatty acid oxidation.

The aim of this work is assessing diagnostic performance of lung tumour markers. Three clinical laboratory tests were used for indicating lung malignancy in order to verify or predict the patient’s diagnosis. The data set of 182 patients was examined and two main groups of the patient samples were created – 86 with diagnosed malignancy (confirmed by histology) and 96 with diagnosed benign tumours or tuberculosis. The following tumour markers were analyzed: carcinoembryonic antigen and cytokeratin 19 fragment, which were sampled in the pleural exudates, and the same tumour markers in serum. In addition, the patient’s age and the gender of the corresponding individual were used as further variables in the original data matrix. Three laboratory tests were used for indicating lung malignancy in order to verify or predict the patient’s diagnosis not only by using the results of the chosen individual laboratory test but also applying multivariate statistical approach, which jointly utilizes all performed tests in the form of their optimal linear combination.

In this article are reviewed the promising uses of phage display in the areas such as microbial pathogens detection of and vaccination. Phage display is a molecular technique by which foreign proteins are expressed at the surface of phage particles. Such phages thereby become vehicles for expression that not only carry within them the nucleotide sequence encoding expressed proteins, but have also the capability to replicate. Recent data acquired from genome sequencing and advances in phage biology research have aided the development of phage-derived bacterial detection and treatment strategies.

The aim of this work was to analyze the supply of vine by nutrients by determining the content of nitrogen, phosphorus, potassium, calcium and magnesium in the vineyard soil and the vine leaves. Its further goal was to discover mutual relationships among the content of determined nutrients, the vine crop, and the quality of the produced must. Must quality was here defined by the contents of sugar and acids. The final goal was to investigate the relations among the nutrients, vine crop and its quality and meteorological factors measured during the whole year cycle, and especially at the time of important vegetation changes. The necessary evaluations were performed using multidimensional data analysis.

Contamination of the aquatic environment by the heavy metals and radionuclides has become a serious concern in the world. In our study, gamma-spectrometry of freshwater plants Bacopa monnieri and Egeria densa growing in cultivation media spiked with 137CsCl and 60CoCl2 was used for quantitative determination of bioaccumulation kinetic and distribution Cs+ and Co2+ ions in plant tissues. We found, that bioaccumulation of Cs and Co by fully immersed B. monnieri in Hoagland media (HM) was dependent on ion concentration in medium. Approx. 5-times lower Cs uptake 2.9 nmol/g (d.w.) was obtained in plants cultivated in 20% HM than from deionized water. The maximal Co uptake was 4-times higher than cesium uptake at the same conditions. Both Cs and Co were localized mainly in roots. The highest immobilization from roots to shoots was found in the case of Co uptake from deionized water with concentration ratio [Co]leaves : [Co]stem : [Co]root = 1.00 : 5.33 : 56.8. Cesium uptake by submerged plant E. densa was also strongly dependent on nutrients concentration in medium. However, in the case of cobalt uptake this dependence was less pronounced. Nutrients concentration also had a significant influence on distribution of Cs between stems and leaves of E. densa. Cesium was localized in leaves, however with increasing of nutrients concentration in cultivation media Cs was localized for account of stem. On the other hand, cobalt was immobilized mainly in leaves in whole range of nutrients concentration. Obtained data can serve as a models for understanding of phytoaccumulation of radionuclides from open water ponds and water channels in the vicinity of nuclear power plants and monovalent and bivalent metals from industrial sources of contamination.

Many streptomycetes strains are hardly or not at all transformable via protoplasts, or there is a problem with the regeneration of protoplasts. We found that protoplasts are formed directly in cultivation media under submerged conditions in the presence of lytic enzyme. Actinophage μ1/6 endolysin and lysozyme were used in this study. Streptomyces strains were cultivated in several media with glycine and lytic enzyme for 24 and 48h. The highest amounts of protoplasts (about 3 x 107 cfu/ml of cultivation medium) together with the highest regeneration (95%) and transformation frequency (about 2 x 106 – 107 cfu/μg DNA) were obtained reproducibly in YEME medium with high sucrose content. S. aureofaciens B96, as hardly transformable strain because of difficulties with protoplast preparation and their further regeneration, was used in this study. The same procedure was applied to S. lividans 66 TK24 and S. coelicolor A3(2), streptomycetes model strains, to confirm the general use of this method. Moreover, such cultivation process was appropriate for additional quick isolation of either chromosomal as well as plasmid DNA that could be further used in recombinant DNA techniques.

In this study, sequences analysis of some Citrus species distributed in Turkey's Aegean region was based on the cpDNA psbA-trnH region. The sequences for psbA-trnH regions of the outgroups were retrieved from NCBI GenBank. Genomic DNA was isolated from healthy and green leaves. Total genomic DNA was extracted using GeneMark DNA isolation Plant Kit. The psbA-trnH region was amplified using primers psbA and trnH. DNA sequences were edited using the Sequencher 5.4.6. Sequencing data were analyzed using MEGA 6.0 software. Maximum likelihood (ML) tree was created to determine the relationships between Citrus taxa. cpDNA psbA-trnH sequences ranged between 426 and 470 nucleotides. Maximum likelihood phylogenetic tree is composed of two clades. The divergence values differed between 0.000 and 0.012. According to the results of the study, the separation of Citrus species in phylogenetic tree obtained with psbA-trnH sequence data was realized. However, it has been found that cpDNA psbA-trnH sequence populations of species belong together. In addition, the phylogenetic relationship between the sequence data of some species belonging to the Rutaceae family taken from NCBI and Citrus species was revealed.

Amylolytic enzymes represent a group of starch hydrolases and related enzymes that are active towards the α-glycosidic bonds in starch and related poly- and oligosaccharides. The three best known amylolytic enzymes are α-amylase, β-amylase and glucoamylase that, however, differ from each other by their amino acid sequences, three-dimensional structures, reaction mechanisms and catalytic machineries. In the sequence-based classification of all glycoside hydrolases (GHs) they have therefore been classified into the three independent families: GH13 (α-amylases), GH14 (β-amylases) and GH15 (glucoamylases). Some amylolytic enzymes have been placed to the families GH31 and GH57. The family GH13 together with the families GH70 and GH77 constitutes the clan GH-H, well-known as the α-amylase family. It contains more than 6,000 sequences and covers 30 various enzyme specificities sharing the conserved sequence regions, catalytic TIM-barrel fold, retaining reaction mechanism and catalytic triad. Among the GH13 α-amylases, those produced by plants and archaebacteria exhibit common sequence similarities that distinguish them from the α-amylases of the remaining taxonomic sources. Despite the close evolutionary relatedness between the plant and archaeal α-amylases, there are also specific differences that discriminate them from each other. These specific differences could be used in an effort to reveal the sequence-structural features responsible for the high thermostability of the α-amylases from Archaea.

Bread wheat (Triticum aestivum L.) plays a major role among the few crop species being extensively grown as staple food sources. As the human population grows, new methods and approaches must be found to attain wheat cultivars with improved characteristics. The challenge now is to produce higher-yielding varieties with good technological quality that are resistant or tolerant to a wide range of biotic and abiotic stresses. However, because of the critical nutritional status of human population, there is an urgent need for development of such wheat varieties that would be more nutritious (with improved protein, zinc, iron, etc. value), meeting our health demands. This article summarises present status in this field.
