    We report the synthesis of a Schiff base 1-(E)-[(6-methoxy-1,3-benzothiazol-2-yl)imino]methyl] naphthalen-2-ol from the reaction of 2-hydroxy-1-naphtaldehyde with 2-amino-6-methoxybenzothiazole. The molecular structure of the title compound was experimentally determined using X-ray single-crystal data and was compared to the structure predicted by theoretical calculations using density functional theory (DFT). In addition, nonlinear optical (NLO) effects of the title compound was predicted using DFT. The colorimetric response of the title compound in DMSO to the addition of equivalent amount of anions (F-, CN-, H2PO4-, OH-, Br-, I-, SCN-, ClO4-, HSO4- N-3(-) and AcO-) was investigated. In this regard, while the addition of F-, CN-, H2PO4-, OH-, and AcO- anions into the solution containing the title compound resulted in a significant color change, the addition of Br-, I-, SCN-, ClO4-, HSO4- and N-3(-) anions resulted in no color change. The most discernable color change in the title compound was caused by CN-, which demonstrated that the title compound can be used to selectively detect CN-. The order of anion-binding power of the title compound was determined to be OH- > CN- > F- similar to AcO- > H2PO4-. The interactions between the receptor and anions were investigated using H-1 NMR titration method. Theoretical and UV-VIS spectroscopy studies of the interactions between the title compound and calf thymus DNA (CT-DNA) showed that the title compound interacts with CT-DNA via intercalative binding.

    The macroanatomy of the brachial plexus and its nerves in the common buzzard (Buteo buteo)
    (UNIV ZAGREB VET FACULTY, 2017) Akbulut, Yalçın; İlgün, Ramazan; Yılmaz, Bestami; Aslan, Kadir; Uzlu, Erdo?an
    The purpose of this study was to elucidate the anatomical structure of the brachial plexus in the common buzzard (Buteo buteo). Five common buzzards (two females and three males) provided by the Wildlife Rescue and Rehabilitation Centre of Kafkas University were used. The nerves of the brachial plexus and the accessory brachial plexus were dissected and photographed. Two plexuses were found the brachial plexus and the accessory brachial plexus. It was also found that the v. jugularis, the a. carotis communis and the n. vagus were located medially of the brachial plexus, while the v. subclavia and the a. subclavia were located in the caudal part of the plexus. In addition, it was observed that the accessory brachial plexus was located in the cranial region, and that it originated from a merger of the ventral branches of cervical spinal nerve 10 and 11 (C10 and C11). The mean diameters of C10 and C11 were measured as 0.49 +/- 0.07 and 0.69 +/- 0.10 mm, respectively. It was found that the brachial plexus originated from a merger of the ventral branches of the last three cervical spinal nerves (C11, C12, and C13) with the ventral branches of the first two thoracic (T1 and T2) spinal nerves. There was no gender difference in terms of the formation of the brachial plexus and the accessory brachial plexus. The diameters of these branches, which joined at the point of origin of the brachial plexus, were measured as 0.69 +/- 0.10 (C11), 1.27 +/- 0.04 (C12), 2.13 +/- 0.11 (C13), 1.81 +/- 0.14 (T1) and 0.98 +/- 0.14 mm (T2). Thus, the formation of the brachial plexus in the common buzzard, the spinal nerves that formed the plexus, and the innervation areas of these nerves were observed and presented.
