Turkish Journal of Chemistry
A short and easy route is described for 6,8-disubstituted derivatives of quinoline and 1,2,3,4-tetrahydroquinoli- ne from 6,8-dibromoquinolines 2 and 7 by various substitution reactions. While copper-promoted substitution of 6,8-dibromide 2 produced monomethoxides 3 and 4, a prolonged reaction time mainly afforded dimethoxide 6 instead of 5, whose aromatization with DDQ and substitution reaction of dibromide 7 with NaOMe in the presence of CuI also gave rise to dimethoxide 6. Several 6,8-disubstituted quinolines were obtained by treatment of 6,8-dibromoquinoline (7) with n-BuLi followed by trapping with an electrophile [Si(Me)_3Cl, S_2(Me)_2, and DMF]. Furthermore, 7 was also converted to mono and dicyano …

Hybridisation Or Vocal Mimicry? A Case Of A Mixed Singing River Warbler Locustella Fluviatilis In Eastern Poland, Michal Polakowski, Monika Broniszewska, Lukasz Jankowiak, Tomasz Cofta
Hybridisation Or Vocal Mimicry? A Case Of A Mixed Singing River Warbler Locustella Fluviatilis In Eastern Poland, Michal Polakowski, Monika Broniszewska, Lukasz Jankowiak, Tomasz Cofta
Turkish Journal of Zoology
The unusual mixed song of a River Warbler (Locustella fluviatilis) was recorded in eastern Poland. The identified male used 2 types of songs recalling the River Warbler and the Grasshopper Warbler (Locustella naevia) alternately, which was confirmed by the interpretation of the sonograms. The most likely explanation of this unusual song is vocal mimicry, caused by the exposure of the recorded individual to the song of the Grasshopper Warbler in its acoustic environment at an early stage of its life.

Turkish Journal of Biology
A leucine-rich repeat-containing protein kinase (LRR-PK) gene has been identified in Corchorus capsularis. This gene, named CcLRR-RLK1, is 3032 bp long and encodes a protein composed of 958 amino acid residues. The deduced peptide contains 3 distinctive domains: a transmembrane domain, 5 leucine-rich repeat-containing motifs, and a serine/threonine protein kinase domain. Expression analysis indicated that the gene is reduced by several environmental stresses including high salt, fungus, and abscisic acid, suggesting its possible involvement in multiple stress response pathways.

Cytotoxic Activities Of Some Pseudomonas Aeruginosa Isolates: Possible Mechanisms And Approaches For Inhibition, Ghadir Saeed El-Housseiny, Mohammad Mabrouk Aboulwafa, Nadia Abdelhaleim Hassouna
Turkish Journal of Biology
The cytotoxicity of 6 highly cytotoxic Pseudomonas aeruginosa isolates was tested against Vero cells. Cytotoxicity was found to be cell-associated, high cytotoxicity was observed at a multiplicity of infection of 200:1, and this activity gradually decreased as the bacterial count decreased. This cytotoxicity caused rounding and detachment of the Vero monolayer as early as 1 h after infection. Moreover, viable metabolically active bacteria were necessary for Vero cell killing. These results imply that one or more of the type III secretion system effector proteins (ExoU, ExoS, ExoT, or ExoY) were responsible for the observed cytotoxic effects. This cytotoxicity was affected …
