Synthesis and pharmacological activities of some new 2-[1-Heptyl-3-(4-methoxybenzyl)-5-oxo-1,5-dihydro-4H-1,2,4-triazol-4-yl] acetohydrazide derivatives
(Walter de Gruyter Gmbh, 2014)
In the present investigation, the key intermediate acetohydrazide derivative 5 was synthesized starting from 3-(4-methoxybenzyl)-4-amino-4,5-dihydro-1,2,4-triazol-5-one (1) by a four-step reaction. Thiosemicarbazides 6a-f ...
Pollen morphology and anatomical features of Lilium (Liliaceae) taxa from Turkey
(Springer, 2014)
In this study, pollen grains and anatomical features of Turkish lilies were investigated under the electron (SEM) and light (LM) microscope. LM and SEM observations showed that the pollen grains are monosulcate, heteropolar, ...
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 ...
Carriage of class 1 and 2 integrons in acinetobacter baumannii and pseudomonas aeruginosa isolated from clinical specimens and a novel gene cassette array: bla(OXA-11)-cmlA7
(Ankara Microbiology Soc, 2014)
The dissemination of antibiotic resistance genes between bacteria leads to serious problems in the treatment of infectious diseases. It has been shown that resistance genes can also be carried by the integrons. There are ...
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♂♂, ...
