Sudaki Yaşam Sürdürülebilir kalkınma için okyanusları, denizleri ve deniz kaynaklarını korumak ve sürdürülebilir kullanmak Sürdürülebilir Kalkınma Hedefleri, deniz ve kıyı eko-sistemlerini sürdürülebilir biçimde yönetmeyi, kirlenmeden korumayı ve ayrıca okyanus asitlenmesinin etkilerini ele almayı hedefliyor. Uluslararası hukuk vasıtasıyla korumanın ve okyanus temelli kaynakların sürdürülebilir kullanımının artırılması, okyanuslarımızın karşı karşıya olduğu sorunların bazılarının hafifletilmesine katkıda bulunacaktır.

    Studies on the Morphology, Anatomy and Ecology of Anacamptis pyramidalis (L.) L.C.M. Richard (Orchidaceae) in Turkey
    Morphological, anatomical and ecological characteristics of Anacamptis pyramidalis (L.) L. C. M. Richard in Turkey were investigated in this study. Plant materials of A. pyramidalis were provided from 21 native populations between 2007 and 2009 in Turkey, and their localities were recorded. A. pyramidalis samples were evaluated within 19 morphological, 20 anatomical, and 18 soil characters & habitat properties. The findings of this study are as follows: The plant length was minimum 248 mm and maximum 655 Iran, underground part length minimum 23 mm and maximum 140 mm, and number of leaves change between 2 and 14. The leaves were tetrastic, had no trichomes. In surface section of the leaves, the cuticle thickness (abaxial and adaxial), epidermis cell size (abaxial and adaxial) stomata dimensions and stomata index were measured. The epidermal cells- rows were parellel to the midrib. In cross sections of the leaves, upper epidermis was larger than lower epidermis. Vascular bundles were collateral and consist of xylem, phloem and sclerenchyma cells. Raphide bundles were observed in the mesophyll tissue and leaf midrib had lacunas. Chlorenchyma had scattered homogeneously. According to habitat definition of A. pyramidalis it grows from sea level to 1600 m whereas the most common habitat of A. pyramidalis are meadow, macchie and gaps in the forest lands. A. pyramidalis are grown in stony soils and also are rich in clay, and medium in organic carbon. pH of the soils differ from 6.77 to 7.54.

    A literature review of MTHFR (C677T and A1298C polymorphisms) and cancer risk
    (2013-01-01T00:00:00Z) Izmirli, Muzeyyen
    5,10-Methlenetetrahydrofolate reductase (MTHFR) is one of the most important enzymes for folate metabolism. This enzyme is mapped on chromosome 1, which is located at the end of the short arm (1p36.3). The C677T and A1298C are MTHFR polymorphisms that decrease in vitro MTHFR enzyme activity. Folate metabolism plays a key role in cell metabolism. These reactions are associated with purine-pyrimidine synthesis: DNA, RNA, and protein methylation. Polymorphism is also a factor in biodiversity, and be affected by ethnic heritage and geographic locale. In the case of unknown outcomes, not only should all geographical regions be investigated to ascertain biodiversity, but all populations as well to fully understand the variations in the effect. PUBMED was searched from January 2006 to December 2011 to develop an investigatory pursuit strategy. MTHFR, cancer, C677T, A1298C, and polymorphisms were key words used to focus the search. The literature review included all published relevant cancer types and MTHFR polymorphisms for that 5 years period. All selected polymorphisms data for cancer types was listed in tables for easy access and retrieval.

    Studies on the chorology, ecology, morphology and conservation strategies of Orchis anatolica Boiss (Orchidaceae)
    (2012-04-01) Altundag, Ernaz; Sevgi, ECE; Kara, Omer; Sevgi, Orhan; Tecimen, Huseyin Baris; Bolat, Ilyas; SEVGİ, ECE
    Orchis anatolica Boiss. is one of the Mediterranean species, which has wide distribution in Turkey. In this study, plant and soil samples of O. anatolica were taken from 26 natural populations in Turkey. There were one hundred ninety locality records in the Mediterranean region of Turkey, but we recorded two hundred sixteen localities thus adding twenty six new localities to the list. Twenty morphological parameters of O. anatolica were evaluated. The correlation coefficients between generative characters and vegetative characters were lower than the character groups of correlation coefficients between themselves. It is found from sea level upto 1700 m. Most common habitats of O. anatolica are macchie, forest lands and stony soils. The soils are loamy, clayey- loam and sandy-clayey- loam and rich in organic matter. The pH of the soils varies from 5.87 to 7.92. Although O. anatolica has wide distribution in Turkey, different types of land uses are posing a threat for it and restricting its distributional area. Lacking the legal regulations about conservation of the O. anatolica populations is one of the most striking requirement.
