39 spatial arrangement of the animal male germ cell genome: II. 2d-3d Simulation and visualization of spatial configuration of major chromosome 2 in Drosophila sperm
(İstanbul Kültür Üniversitesi, 2007-09) Alexandrov, Igor D.; Stepanenko, Victor A.; Alexandrova, Margarita V.
Data on the non-random distribution of radiationinduced inversion breakpoints were used as genetic markers for 2D and 3D modeling of the largescale architecture of the chromosome 2 in Drosophila sperm genome at the time of irradiation. During modeling, Gmax program with application of splines, the additional objects and operations as well as the methods of visualization of macromolecular biostructures were employed. A specific megarosette-loop model of spatial arrangement of chromatin fiber in the haploid sperm nucleus can account well for the experimental data.

Aluminum toxicity and resistance in higher plants
(İstanbul Kültür Üniversitesi, 2007-03) Vardar, Filiz; Ünal, Meral
Aluminum (Al) is the major element in the soil and exists as a stable complex with oxygen and silicate. When the soil pH is below 5, Al is solubilized in the soil water and absorbed by plant roots. Absorbed Al inhibits root elongation severely within hours. Al toxicity is a very important limitation to worldwide crop production, because 50% of the world’s potentially arable lands are acidic. Thus, many research has been conducted to understand the mechanism of Al toxicity and resistance which is important for stable food production in future. Al resistance can be achieved by mechanisms that facilitate Al exclusion from the root apex and/or by mechanisms that confer the ability of plants to tolerate Al in the plant symplasm. However, despite intense research efforts, there are many aspects of Al toxicity and resistance remain unclear. In this review, Al toxicity and resistance mechanisms are described with the physiological and molecular basis.

Characteristics of Fabricated Soil for Landscape Rehabilitation: The Four Crop Test for Biological Activity
(İstanbul Kültür Üniversitesi, 2008) Kefeli, Valentine; Leininger, Christopher; Mastalski, Shari; Kimberly, Pincin
Fabricated soil (FS) is a mixture of substrates containing balanced amounts of carbon, nitrogen, phosphorus, potassium and mineral elements that support plant growth . In our experiments, we use FS for the rehabilitatio n of land f r om mining soil pollutants. Characteristics of fabricated soil were determined including measurements of N, P, K; other nutritive elements including Mg, Ca, S, and Fe; and micro-elements and toxic elements including Mn, Zn, A l , Ni, and Pb. Also , microbial activity of the soil was tested to determine fungal and bacterial presence. After investigating these soil characteristics, we used a four - crop test to investigate fabricated soils and related substrates for biological activity. Soil health includes a balance of mineral and organic elements and healthy microbial activity. These characteristics play the key role in the soil ' s ability to support the growth of higher plants which complete the regenerative process of soil cycling. Healthy soils provide materials for food, energy, and shelter. Healthy soils are crucial to all biological, geological, and water cycles.

Cytological evidences of the role of Meta-topolin and Benzyladenin in barley root tips
(İstanbul Kültür Üniversitesi, 2008) Huyluoğlu, Zekiye; Ünal, Meral; Palavan-Ünsal, Narçin
The responses of mitotic activity affecting root growth to benzyladenine (BA) and meta-topolin (mT) which is thought to be alternative of BA were studied with time and dose dependent experiments in Hordeum vulgare Tarm-92. The all concentrations of mT caused an induction on mitotic index. 10-5 mT was the most effective stimulator, increasing division frequency from 16 to 26 BA treatment exhibited variations; the low concentrations (10-5 M and 10-6 M) increased the mitotic index but the higher concentration (10-4 M) decreased. The values of mitotic index reflected to the elongation of roots, coordinately. BA and mT are both affected chromosomal behavior and caused abnormalities such as unoriented metaphase, chromosome bridges, 2 nucleate cells, micronuclei formation.

Determination of HER2/NEU gene amplification and protein overexpression ib bladder transitional cell carcinoma
(İstanbul Kültür Üniversitesi, 2007-09) Atış, Gökhan; Arısan, Serdar; Ayhan, Dalkılınç
HER2/neu 185 kDa is a transmembrane receptor tyrosine kinase being a part of epidermal growth factor receptor family. Especially overexpression was shown in breast cancer and treatment procedures targeting this protein are in clinical use. The aim of this study is to show the overexpression of HER2/neu in bladder TCC patients by using immunohistochemical methods. 46 TCC and 15 healthy bladder tissues as a control group were used in the study. Deparafinized tumor specimens were marked by using monoclonal antihuman HER2 protein antibody and the protein was shown by using peroxidase secondary antibody. Non-staining or membrane staining less than 10% were classified as 0, while membrane staining partly more than 10% were 1, poor complete membrane staining or moderate staining more than 10% were 2 and complete membrane strongly staining were classified as 3. Classification 2 and 3 were evaluated as over staining of HER2/neu. Overexpression of HER2/Neu protein were shown in 12/46 (24.5%) of TCC specimens. Overexpression of HER2/neu were detected in 2 (12.5%) of Grade 1, 1 (16.6%) of Grade 2 and 12 (50%) of Grade 3 patients. Overexpression of HER2/Neu protein were positive in 5 (17.8%) of 28 superficial (Ta-T1) tumor specimens and 7 (38.8%) of 18 invasive (T2-T3) tumor specimens. Overexpression of HER2/neu in Grade III tumors were statistically significant when compared with Grade I and Grade II (p=0.012). Overexpression of HER2/neu detected in bladder TCC will be used in clinical setting as a treatment option targeting this protein as in the breast cancer in the future.

Determination of IL-10 levels in chronic pelvic pain syndrome patients
(İstanbul Kültür Üniversitesi, 2008) Arısan, Serdar; Kiremit, Murat Can; Ergenekon, Erbil; Çaşkurlu, Turhan
Chronic pelvic pain syndrome (CPPS) is very common pathology that is characterized by pain in the perineum, pelvis, supra pubic area, or the external genitalia, with variable degrees of voiding or ejaculatory disturbance. The etiology of disorder is controversial with groups postulating infections, autoimmune, inflammatory and neuromascular mechanism. CPPS is the most commonurologic diagnosisin men younger than 50 years and the third most common urologic diagnosis in men older than 50 years after benign prostate hyperplasia and prostate cancer. Although high incidence rate, the etiology and pathophysiology of the disease are still poor.

Many digital games with different contents are played by children with special needs. The research was carried out with the parents of diagnosed children aged 6-13 years. The aim of the research is to determine the views of parents of children with special needs on digital games. The research was designed with phenomenology (phenomenology), one of the qualitative research methods, and the data were created and analyzed using content analysis. A semi-structured interview form and a questionnaire containing demographic information were used in the research. As a result of the data, codes were created and thanks to them, themes and sub-themes were reached. In the research, digital game theme and sub-themes were reached. In consequence of them, it was obtained that children with special needs mostly prefer war games, their purpose of playing games is entertainment, they mostly prefer mobile phones while playing games, and they play games for at least two hours a day. In addition to the findings that digital games contribute positively to the educational processes, skills and development of children with special needs, there were also findings that digital games have negative effects such as children not being able to spare time for their lessons and spending all their time in digital games.
