Turkish Journal of Chemistry
Marine compound dendrodoine was first obtained from tunicate species (Dendrodo grossularia). It has a five-membered ring, namely, it is a heterocycle thiadiazole, which is found rarely in natural sources. Following its biological activities, novel analogs have been investigated recently. Synthesis of the analogs for this study is realized with uncommon thiazole closure, including methylene-carbonyl condensation. Structures are elucidated by NMR (1H, 13C) and HRMS spectrums. As an alkaloid derivative, antioxidant properties were evaluated with DPPH and FRAP assays and antimicrobial effect with microdilution method. Among the series, 3bc-3cf showed higher antioxidant activity than those having 3 or 4-pyridyl substituents. There …

Turkish Journal of Chemistry
Choline derivatives were covalently immobilized on the surface of γ -aminated silica. The obtained immobilized choline derivative was then successfully used for a transesterification reaction to produce glycerophosphocholine (GPC). Fourier transform infrared analysis and thermogravimetric analysis/differential thermal gravimetry indicated that the surface of the γ -aminated silica was covered by choline derivatives and the highest immobilization amount reached 1.1 mmol/g under optimal conditions. More importantly, the highest yield of GPC reached 97.9% during transesterification. With regard to GPC in food or medicine for human use, the immobilization technology can avoid catalyst contamination of the product and increase the safety of …

Turkish Journal of Medical Sciences
Background/aim: Gastric cancer (GC) is one of the major causes of cancer mortality worldwide. As a novel type of endogenous noncoding RNAs, circular RNAs (circRNAs) are formed by a covalent link between 5' and 3' ends. They are very stable and abundant in eukaryotes. As there were no reported studies on the expression profiles of circular RNA ITCH (cir-ITCH) and circHIPK3 in GC, in the current study, we aimed to delineate the expression profiles and clinicopathological relevance of these two circRNAs in GC tissues compared to their paired adjacent noncancerous tissues.Materials and methods: Quantitative real-time polymerase chain reaction was performed …

Characterisation Of Chitin In The Cuticle Of A Velvet Worm (Onychophora), Hartmut Greven, Murat Kaya, İdri̇s Sargin, Talat Baran, Reinhardt Møbjerg Kristensen, Martin Vinther Sorensen
Turkish Journal of Zoology
We characterize the trunk cuticle of velvet worms of the Peripatoides novaezealandiae-group (Onychophora) using SEM, TEM, Fourier transform infrared spectroscopy (FT-IR), and thermogravimetric analysis (TGA). TEM and SEM revealed a relatively uniform organization of the delicate cuticle that is covered by numerous bristled and nonbristled papillae with ribbed scales arranged in transverse rows. The cuticle consists of a very thin multilayered epicuticle of varying appearance followed by the largely fibrous procuticle. The irregularly arranged nanofibres of isolated cuticular chitin seen by SEM are considered as bundles of chitin fibres. FT-IR and TGA showed that the chitin is of the α-type. …

Community Detection In Complex Networks Using A New Agglomerative Approach, Majid Arasteh, Somayeh Alizadeh
Turkish Journal of Electrical Engineering and Computer Sciences
Complex networks are used for the representation of complex systems such as social networks. Graph analysis comprises various tools such as community detection algorithms to uncover hidden data. Community detection aims to detect similar subgroups of networks that have tight interconnections with each other while, there is a sparse connection among different subgroups. In this paper, a greedy and agglomerative approach is proposed to detect communities. The proposed method is fast and often detects high-quality communities. The suggested method has several steps. In the first step, each node is assigned to a separated community. In the second step, a vertex …
Effect Of Some Immunomodulators And Zeatin On Susceptibility Of Wheat To Powdery Mildew, Alexander Babosha
Effect Of Some Immunomodulators And Zeatin On Susceptibility Of Wheat To Powdery Mildew, Alexander Babosha
Turkish Journal of Botany
The effects of zeatin, salicylic acid, and plant oligoadenylates on susceptibility of wheat seedlings to powdery mildew and the shape of dose-response curves for immunomodulation were studied. Salicylic acid and zeatin produced complex dose-responses with upregulation or downregulation of plant susceptibility. Under different experimental conditions, the dose-response curve for zeatin varied in shape from a curve with a maximum to a curve with a minimum of susceptibility to powdery mildew. More complicated curves with a resistance region framed with regions of increased susceptibility were also found. Plant oligoadenylates inhibited the development of powdery mildew at optimal concentrations. The increasing concentrations …

Turkish Journal of Veterinary & Animal Sciences
The correlations between selected egg, embryo development, and chick traits were analyzed in three lines of Japanese quail subjected to intrafamily selection for 28th day body weight (group S) and in three lines of random control birds (group K). The significant correlation coefficients between egg weight and most of the traits observed after the first two days of incubation as well as chick weight and shank length were estimated. Most of the correlations obtained were significant in both groups. No statistically significant differences between groups were confirmed, but there was a lines effect within the groups in most cases and …

Turkish Journal of Veterinary & Animal Sciences
The objective of this study was to investigate whether there is an association between ovarian stimulation and interrupted gamete interaction in the rat fallopian tube in vivo. We evaluated the protein expression of interleukin-1ß (IL-1ß) via immunohistochemistry and assessed the key histological features of the ovaries, fallopian tubes, and uteri of the rats following treatment with mild (15 IU) and high (30 IU) doses of gonadotropins compared to an unstimulated control group. The serum concentration of estradiol was also determined by immunoassay. The results revealed that high levels of circulating estrogen were associated with higher expression of the IL-1ß protein …

The aim of this study was to assess serum asymmetric dimethyl arginine (ADMA), cardiac troponin I (cTnI), thyroxine (T4), cholesterol and triglyceride (TG) levels in dogs with normal body condition and obese dogs. A total of 40 dogs (n = 40) were included in the study and dogs were divided into two groups; 20 dogs with normal body condition and 20 obese dogs. The dogs were grouped according to the five-point body-condition scoring (BCS) system. Serum ADMA, cTnI, T4, cholesterol, and TG levels were measured in addition to routine biochemical parameters. Serum ADMA, cTnI, TG, and cholesterol levels were statistically …

This study was designed to evaluate serum and electrocardiographic (ECG) changes in cattle with foot-and-mouth disease (FMD). Thirty-two cows with clinical signs of FMD and 13 healthy cows were randomly enrolled. After blood sampling, ECG was performed on 23 of the 32 ill cows. Serum circulatory troponin I (cTnI), CPK, LDH, and CK-MB activities were determined in the patient and control groups. Arrhythmias including ventricular tachycardia (VT), sinus tachycardia (ST), atrial fibrillation (AF), and premature ventricular complex (PVC) were seen in 4, 4, 2, and 1 of the patients, respectively. The patients had higher cTnI levels than the control group …

Specimens of Oreochromis niloticus (One control and 3 experimental groups) were fed diets mixed with different doses of mercury (control group = free of mercury; group 1 = 500 mg/kg; group 2 = 750 mg/kg, and group 3 = 1000 mg/kg) for 60 days in order to study its accumulation and histopathological alterations in the liver, gills, skeletal muscles, and skin. The results obtained revealed that mercury accumulation was significantly (P < 0.05) high in the liver and gills compared to the muscles and skin. The order of accumulation in these organs revealed to be liver > gills > muscles > skin. The fish fed various doses of mercury also showed histological alterations in these organs. Epithelial lifting and epithelial hypertrophy were seen in the gills of the …
