Abstract The Mesoproterozoic MARA terrane of western South America is a composite igneous-metamorphic complex that important for Paleozoic paleogeographic reconstructions and the relative positions Laurentia Gondwana. magmatic detrital records are consistent with Laurentian origin; however, metamorphic deformation lack sufficient detail to constrain correlation units within timing mechanisms ac...

Şehir ve medeniyet kavramları arasında kop(arıl)maz bir bağ vardır. Geçmişten bugüne medeniyetler şehirleri kurar, şehirler medeniyetlerin sembolleri olur. Kadim şehirlerin oluşumu uzun süreç almıştır. Dünya üzerinde geniş coğrafyaya yayılan Türkler, tarihin farklı dönemlerinde inşa ettikleri şehirlere kendi mühürlerini vurmuşlardır. Öyle ki bu şehirlerden bazıları Türklerin hâkimiyetinden çıks...

The gastric hormone gastrin regulates the expression of a variety of genes involved in control of acid secretion and also in the growth and organization of the gastric mucosa. One putative target is plasminogen activator inhibitor-2 (PAI-2), which is a component of the urokinase activator system that acts extracellularly to inhibit urokinase plasminogen activator (uPA) and intracellularly to su...

The fibroblast growth factor receptor 2 (FGFR2) gene exons IIIb and IIIc are alternatively spliced in a mutually exclusive and cell type-specific manner. FGFR2 exon choice depends on both activation and silencing. Exon IIIb silencing requires cis-acting elements upstream and downstream of the exon. To examine the influence of transcription on exon IIIb silencing, the putative RNA polymerase II ...
