Microwave-assisted preparation of azachalcones and their N-alkyl derivatives with antimicrobial activities
(Taylor & Francis Ltd, 2014)
Two new azachalcones were prepared by both Claisen-Schmidt condensation and a simple environmentally trendy microwave-assisted method. Ten new N-alkyl (C-6,C-8,C-10,C-12,C-14)-substituted azachalconium bromides (3a-e, 4a-e) ...
Variation in body size and age structure of stellagama stellio (L., 1758) (Reptilia: Agamidae) from Turkey
(Inst Zoology, Bas, 2014)
Age and body size of 81 Stellagama stellio (syn. Laudakia stellio) specimens from five regions of Turkey were studied using skeletochronology. Lines of arrested growth (LAGs) in phalanges were used to estimate the age. ...
Investigation of the internal bacterial flora of Eurygaster integriceps (Hemiptera: Scutelleridae) and pathogenicity of the flora members
(Springer, 2014)
Eurygaster integriceps (Hemiptera: Scutelleridae) is one of the most serious pest of wheat and other cereal crops throughout the Near and Middle East including Turkey. To contribute biological control of this pest, we ...
A skeletochronological study of the smooth newt Lissotriton vulgaris (Amphibia: Urodela) from an island and a mainland population in Turkey
(Taylor & Francis Ltd, 2014)
To understand the effects of island and mainland on life history traits (e. g. longevity, age at maturity, body size and body mass) of the smooth newt Lissotriton vulgaris (Linnaeus, 1758), we generated data on age and ...
Synthesis of some heterofunctionalized penicillanic acid derivatives and investigation of their biological activities
(Wiley-V C H Verlag Gmbh, 2014)
6-Substituted amino-penicillanic acid esters were synthesized starting with 6-apa. the compounds containing a 1,3-thiazole- or 1,3-thiazolidinone nucleus linked to the penicillanic acid skeleton via a hydrazino linkage ...
Age structure and body size in three populations of Darevskia rudis (BEDRIAGA, 1886) from different altitudes
(Osterreichische Gesellschaft Herpetologie E V, 2014)
Darevskia rudis (BEDRIAGA, 1886) occupies a wide range of altitudes in the Black Sea region of Turkey. A total of 62 individuals of this lizard from three populations/locations at different altitudes (Province of Artvin: ...
Preliminary data on the age structure of Asaccus barani (Baran's leaf-toed gecko) from southeastern Anatolia, Turkey
(2015)
In this study, the age structure of an Asaccus barani sample from Şanlıurfa (southeastern Anatolia, Turkey) was determined by skeletochronology for the first time. A total of 17 preserved adults (7♂♂, ...
Synthesis and antimicrobial properties of N-substituted derivatives of (E)-2 ',3 ''-thiazachalcones
(Walter de Gruyter Gmbh, 2015)
N-alkyl substituted 2',3 ''-thiazachalcones {3-[(1E)-3-(4-methylthiophene-2-yl)-3-oxoprop-1-en-1-yl]-1-alkyl (C-5-12,C-14) pyridinium bromides} were synthesized by a two-step reaction. the newly synthesized compounds were ...
Climatic preferences and distribution of 6 evolutionary lineages of Typhlops vermicularis Merrem, 1820 in Turkey using ecological niche modeling
(Tubitak Scientific & Technical Research Council Turkey, 2015)
According to evolutionary biologists, ecology is a very important factor in speciation. Ecology may be effective at driving adaptive divergence between lineages in different environments and climatic conditions. Because ...
Distribution of beta-lactamase genes among carbapenem-resistant klebsiella pneumoniae strains isolated from patients in Turkey
(Korean Soc Laboratory Medicine, 2015)
Background: the emergence of carbapenem-resistant Klebsiella pneumoniae poses a serious problem to antibiotic management. We investigated the beta-lactamases in a group of carbapenem-resistant K. pneumoniae clinical isolates ...
