Synthesis of some new 1,3,4-thiadiazol-2-ylmethyl-1,2,4-triazole derivatives and investigation of their antimicrobial activities
(Elsevier, 2009)
4-Amino-2-[(5-arylamino-4,5-dihydro-1,3,4-thiadiazol-2-yl)methyl]-5-(4-methylphenyl)-2,4-dihydro-3H-1,2,4-triazol-3-ones (3a-c) were obtained in acidic media via the formation of 2-[(4-amino-3-aryl-5-oxo-4,5-dihydro-1H-1 ...
A new DNA polymerase i from Geobacillus caldoxylosilyticus TK4: Cloning, characterization, and mutational analysis of two aromatic residues
(Springer, 2009)
DNA polymerase I gene was cloned and sequenced from the thermophilic bacterium Geobacillus caldoxylosilyticus TK4. The gene is 2,634 bp long and encodes a protein of 878 amino acids in length. The enzyme has a molecular ...
Photochemistry of nitro-substituted (E)-2-azachalcones with theoretical calculations and biological activities
(Elsevier, 2009)
Four new stereoselective dimerization products (4a-c, 5) of m- and p-nitro-substituted (E)-2-azachalcones (2 and 3) were synthesized and tested for antimicrobial and antioxidant activities. Compounds 1-3 showed very good ...
Class 1 and class 2 integrons and plasmid-mediated antibiotic resistance in coliforms isolated from ten rivers in northern Turkey
(2009)
We aimed to determine the molecular mechanisms of antibiotic resistance in coliforms isolated from ten rivers in northern region of Turkey. A total of 183 isolates were tested for antimicrobial susceptibility by disk ...
Climatic envelopes of the genus Lacerta Linnaeus, 1758 in Türkiye: an application of ecological niche modeling
(Springer, 2023)
Six species belonging to the genus Lacerta live in Türkiye. In this study, both present and future potential distribution maps were created based on occurrence data and climatic variables for these six species. Two scenarios ...
Biomonitoring of trace elements with lichens in Samsun City, Turkey
(2010)
Lichens have been widely used in biomonitoring studies. In this study, Cd, Cu, Pb and Zn concentrations in some foliose and fruticose lichens which are found in Samsun were investigated and the differences among the species ...
Molecular characterization and virulence of beauveria spp. from the pine processionary moth, thaumetopoea pityocampa (Lepidoptera: Thaumetopoeidae)
(Springer Link, 2010)
The pine processionary moth Thaumetopoea pityocampa (Den. & Schiff.) is one of the most harmful pests to pine species in Mediterranean countries including Turkey. Caterpillars of T. pityocampa are not only significantly ...
Prevalence of integrons and a new dfrA17 variant in Gram-negative bacilli which cause community-acquired infections
(Wiley, 2010)
A hundred and eleven Gram-negative bacilli from community-acquired infections were characterized by antimicrobial susceptibility testing, screened for class 1 and 2 integrons, and statistically evaluated for the association ...
Isolation and virulence of entomopathogenic fungi against the great spruce bark beetle, Dendroctonus micans (Kugelann) (Coleoptera: Scolytidae)
(Taylor & Francis Online, 2010)
Twelve fungal strains including Lecanicillium muscarium (Petch.) Zare and Gams, Isaria farinosa (Holmsk.) Fr., Fusarium sp., Beauveria bassiana Sensu Lato and Beauveria sp. were isolated from larvae and adults of D. micans. ...
Characterization of tetracycline resistance genes in tetracycline-resistant Enterobacteriaceae obtained from a coliform collection
(Springer, 2010)
Tetracycline resistance has been used as the key determinant to monitor resistance genes in natural environments such as rivers, lakes or seawater. The aim of this study was evaluate the frequency of tetA, tetB, tetC, tetD ...
