    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.

    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.

    Ras oncogenes polymorphism in Turkish thyroid cancer patients
    (İstanbul Kültür Üniversitesi, 2008) Öztürk, Fatma; Daloğlu, Cihan; Açık, Leyla; Kılıç, Mehmet; Koç, Mahmut
    Molecula r mutations to proto - oncogene sequences may be involved in the pathogenesis of human thyroid neoplasm. Problems on oncogenes and tumor supressor genes activation in cell circle could cause tumor. Many oncogenes and tumor suppressing genes exist in varying percentages in various types of thyroid cancers. Ras, Gsp, Ret or Trk oncogenes can be involve in thyroid tumors . Members of t h e Ras gene family (H-ras, K-ras, and N-ras) are signal transferring proteins. These genes codes for 21 kDa GTP binding proteins. We studied 24 thyroid cancer and 77 control for ras gene point mutations in two different codons (12 and 13) using a restriction fragment length polymorphism technique. According to enzyme digesting, no c-K-ras gene codon 12/13 and N-ras gene codon 12 point mutation were observed in any of the samples we studied .

    Wood-bark-cambium relations during willow cloning and the mechanism of rooting in Salix discolor
    (İstanbul Kültür Üniversitesi, 2008) Kefeli, Valentine; Leininger, Christopher; Mastalski, Shari; Rehn, Beth
    The process of pussy willow (Salix discolor) propagation, or cloning, is an important biological process , which allows the increase of the amount of plant lets with the properties of the mother plants. Pussy willow has very weak dormancy. Therefore, the process of rootin g of stem cuttings may proceed ten month s in a year except September and October. We investigated the localization of the rooting process on the stem, performing surgery in the form of girdling of bark and partial stripping of bark with cambium from the stem. The process of rootin g was investigated. We observed that roots are formed only on the bark with cambium. If we strip the bark, no roots on the wood were observed . Rooted cuttings were subjected to preparation and we observed that roots were formed only on the bark - cambium complex . During the preparation of the stem, we did not separate bark from cambium and investigated this complex together.
