To determine the efficacy of lycopene, which is considered an antioxidant agent, in decreasing the cochlear damage induced by cisplatin. Materials and methods: A total of 38 rats were randomized into 4 groups: control, cisplatin, cisplatin + lycopene, and lycopene-treated groups. In all groups, the distortion-product otoacoustic emission measurements were performed on days 0, 1, 2, and 5. Results: There were no significant differences between the control and lycopene groups at any frequencies. In the cisplatin group, the statistically significant differences were found in the measurements taken between day 0 and day 5 at all frequencies and between days 1 …

Sarcoidosis is a complex, multifactorial immune disorder with unknown etiology. A single nucleotide polymorphism ( G->A, rs2076530) in the butyrophilin-like 2 (BTNL2) gene results in a truncating protein formation. It has been previously reported that this variation may be a risk factor for sarcoidosis in certain ethnic groups. This study was conducted to determine whether there is any genetic predisposition for the BTNL2 rs2076530 polymorphism in the 329-bp region in Turkish patients with sarcoidosis. Materials and methods: DNA samples were obtained from volunteers including 53 Turkish patients with sarcoidosis and 52 healthy controls. Analysis of the 329-bp region was …

Prostate cancer is the most commonly diagnosed malignancy and the second most common cause of cancer deaths in the Western male population. Matrix metalloproteinases (MMPs) and tissue inhibitors of MMPs (TIMPs) modulate the remodeling of the extracellular matrix (ECM). The imbalance between MMPs and TIMPs may lead to an emergence of pathological processes such as cancer. In this study, the association between TIMP-2 (-418 G/C) and MMP-2 (-1306 C/T) polymorphisms and prostate cancer in the Turkish population was investigated. Materials and methods: Sixty-one prostate cancer patients and 46 healthy subjects were included in the study. DNA was isolated from 2 …

Impact Of Small-World Topology On The Performance Of A Feed-Forward Artificial Neural Network Based On 2 Different Real-Life Problems, Okan Erkaymaz, Mahmut Özer, Nejat Yumuşak
Turkish Journal of Electrical Engineering and Computer Sciences
Since feed-forward artificial neural networks (FFANNs) are the most widely used models to solve real-life problems, many studies have focused on improving their learning performances by changing the network architecture and learning algorithms. On the other hand, recently, small-world network topology has been shown to meet the characteristics of real-life problems. Therefore, in this study, instead of focusing on the performance of the conventional FFANNs, we investigated how real-life problems can be solved by a FFANN with small-world topology. Therefore, we considered 2 real-life problems: estimating the thermal performance of solar air collectors and predicting the modulus of rupture values …

A Microscopic Approach To The Pedogenic Formation Of Palygorskite Associated With Quaternary Calcretes Of The Adana Area, Southern Turkey, Meryem Yeşi̇lot Kaplan, Muhsi̇n Eren, Selahatti̇n Kadi̇r, Seli̇m Kapur, Jennifer Huggett
Turkish Journal of Earth Sciences
Quaternary calcretes in the Adana area (southern Turkey) are widespread and occur in a variety of forms such as nodular, columnar/tubular, fracture-infill, laminated hardpan, and conglomeratic crusts. Palygorskite associated with calcrete nodules, tubes, and fracture-infills in the columnar horizon and adjacent host-rock mudstones suggests a cogenetic formation. The Beta-fabric (biogenic) constituents and stable isotope values of calcretes support a pedogenic origin for calcretes and also palygorskite. Extensions of palygorskite fibre and fibre bundles from euhedral to subhedral calcite crystals in calcretes and from smectite flakes in adjacent host-rock mudstone suggest an authigenic origin related to calcretisation in which precipitation and …

Turkish Journal of Earth Sciences
This study applied coded spectral ratio imaging and a self-organizing map (SOM) neural network model for subpixel classification of Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data to map alteration minerals of the Masahim volcano, SE Iran. Spectra of samples were measured using a FieldSpec spectroradiometer, and were interpreted for finding key alteration minerals. Key minerals including sericite and kaolinite were selected. Thirty-six nonreciprocal spectral ratios of 9 ASTER reflective bands were created. Each spectral parameter (of 9 spectral bands and 36 spectral ratios) for the field and library mineral spectra was divided into deciles. Each decile of spectral …

Turkish Journal of Chemistry
The oxidation of the anticholinergic drug atropine sulfate monohydrate by hexacyanoferrate(III) in aqueous alkaline media was investigated spectrophotometrically by monitoring the decrease in absorbance of hexacyanoferrate(III) (HCF(III)). Oxidation products were identified. The oxidation mechanism was proposed from kinetic studies. The reaction constants involved in the different steps of the mechanism were calculated. The effects of added products, ionic strength, and dielectric constant of the reaction were investigated. The polymerization test revealed that oxidation occurred with intervention of free radicals. The activation parameters were evaluated.

Quantitative structure activity relationship analyses were used to identify the ideal physicochemical characteristics of potential chalcone derivatives as anti-Leishmania agents. The HyperChem program was used to build chalcone structures and to perform conformational analyses through the semiempirical method followed by the PM3 force field. Dragon calculated a large number of molecular descriptors. Multilinear regression was used for quantitative structure activity relationship modeling. Based on our computational studies, 4 descriptors, SEigv, RDF125v, RDF055u, and O-058, can affect the activity of chalcone derivatives.

The cagA and vacA profiles and their association with clinical findings show a distinct geographical distribution. In the present study, we aimed to determine the cagA status and vacA allelic subtypes in strains isolated from a university hospital in Ankara and to evaluate their associations with histopathological and endoscopic findings. Materials and methods: A total of 120 H. pylori strains from stock cultures positive for the ureA gene were randomly included in the present study. Of these strains, cagA and vacA allelic subtypes (s1a, s1b, s2, m1, m2) were examined by polymerase chain reaction. Results: Of the 120 strains, 64 …

Effect Of Gamma Ray Irradiation And Cryopreservation On Pollen Stainability, In Vitro Germination, And Fruit Set In Citrus, Manoj Kundu, Anil Dubey, Manish Srivastav, Surendra Malik, Bhupinder Singh
Turkish Journal of Biology
The present work analyzed the stainability and in vitro germinability of the gamma-ray-irradiated fresh and cryopreserved pollens of 3 Citrus species: C. limon, C. limetta, and C. sinensis. Fruit set after pollinating 75 flowers of C. grandis with irradiated and nonirradiated (control) fresh and cryopreserved pollen was also assessed. Results showed that in solid and liquid culture media the highest in vitro germination values were detected in fresh (61.45% and 62.53%, respectively) as well as cryopreserved (53.17% and 55.36%, respectively) C. sinensis nonirradiated pollens. However, at a higher irradiation dose of 500 Gy in both culture media, the minimum reduction …

Turkish Journal of Biology
An investigation was done to study the heterotic grouping and patterning in quality protein maize inbreds. Biochemical screening resulted in the choice of 3 inbreds each with high (UQPM 2, UQPM 4, and UQPM 21) and low (UQPM 18, UQPM 19, and UQPM 20) lysine and tryptophan contents respectively for genetic studies using diallel analysis. UQPM 20 × UQPM 18 was notable as it possessed high standard heterosis and specific combining (sca) effect for grain yield, protein, tryptophan, and lysine. Based on yield sca, the 6 parental inbreds were classified into 3 heterotic groups. Intergroup cross UQPM 20 × UQPM …
