Heavy metal accumulation in some natural and exotic plants in Samsun city
(Cevkor Vakfi, 2011)
The aim of this study was to estimate the level of some trace metal accumulation (Pb, Cd, Zn and Cu) in the leaves, needles, and twigs of some natural and exotic tree and shrub species which were selected and tested as a ...
Reduction in membrane phosphatidylglycerol content leads to daptomycin resistance in Bacillus subtilis
(2011)
Daptomycin (DAP) is a cyclic lipopeptide that disrupts the functional integrity of the cell membranes of Gram-positive bacteria in a Ca 2+-dependent manner. Here we present genetic, genomic, and phenotypic analyses of an ...
Molecular identification and distribution of Anopheles maculipennis complex in the Mediterranean region of Turkey
(Elsevier, 2011)
The present study was set to identify the members of An. maculipennis complex, which includes effective malaria vectors, throughout the Mediterranean region of Turkey using the second internal transcribed spacer of ribosomal ...
Chemical composition and antimicrobial activity of the essential oils from evernia prunastri (L.) ach. and evernia divaricata (L.) ach.
(Chemical Publishing Co., 2011)
In present studies, the chemical composition and antimicrobial activity of the essential oil of Evernia prunastri (L.) Ach. and Evernia divaricata (L.) Ach have been analyzed. The essential oils obtained by hydrodistillation ...
Body size and age structure of Pelophylax ridibundus populations from two different altitudes in Turkey
(Brill, 2011)
We estimated differences in body size and age structure of two populations of Pelophylax ridibundus living at different altitudes in Turkey, one from Dörtyol (6 m a.s.l.) and the other from Karagöl (1480 m a.s.l.). Their ...
Effects of selected groundwater chemical traits on a salt marsh community
(2011)
Electrical conductivity, exchangeable sodium ratio and water depth have negative impacts, whereas soil organic matter concentration has a positive impact on Black Sea salt marsh vegetation. The most saline soils were ...
Synthesis and antimicrobial activity of methoxy azachalcones and N-Alkyl substituted methoxy azachalconium bromides
(TÜBİTAK, 2011)
In this study, 18 new N-octyl, N-decyl, and N-dodecyl substituted o-, m-, and p-methoxy (E)-3-and 4-azachalcones, {4-or 3-[(1E)-3-(4-, 3-, or 2-methoxyphenyl)-3-oxoprop-1-en-1-yl]-1-alkyl (C8,10,12) pyridinium bromides} ...
Phenylenediamine, salicylic acid, stoichiometry, formation constant, speplot, metal complexes
(2011)
The present work describes the chemical composition and antimicrobial activity of the essential oil of Campanula olympica Boiss. which was isolated from the all parts of the plant by hydrodistillation and analyzed by GC-FID ...
Chemical composition and antimicrobial activity of the essential oils from the flower, leaf, and stem of Senecio pandurifolius
(2011)
The essential oils from the fresh flower, leaf, and stem of Senecio pandurifolius (Asteraceae) were isolated by hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS. A total of forty-five, ...
The relations between antioxidant enzymes and chlorophyll fluorescence parameters in common bean cultivars differing in sensitivity to drought stress
(Springer, 2011)
Effects of the antioxidant system and chlorophyll fluorescence on drought tolerance of four common bean (Phaseolus vulgaris L.) cultivars were studied. The cultivars were positioned in the order of a decrease in their ...
