A new DNA polymerase i from Geobacillus caldoxylosilyticus TK4: Cloning, characterization, and mutational analysis of two aromatic residues
(Springer, 2009)
DNA polymerase I gene was cloned and sequenced from the thermophilic bacterium Geobacillus caldoxylosilyticus TK4. The gene is 2,634 bp long and encodes a protein of 878 amino acids in length. The enzyme has a molecular ...
The effects of land-use changes on soil properties: The conversion of alder coppice to tea plantations in the Humid Northern Blacksea Region
(2009)
Over the last century, the conversion of natural ecosystems to agricultural production is one of the primary factors in environmental degradation. As in most parts of the world, forest soils in the northeast of Turkey are ...
Photochemistry of nitro-substituted (E)-2-azachalcones with theoretical calculations and biological activities
(Elsevier, 2009)
Four new stereoselective dimerization products (4a-c, 5) of m- and p-nitro-substituted (E)-2-azachalcones (2 and 3) were synthesized and tested for antimicrobial and antioxidant activities. Compounds 1-3 showed very good ...
Factors affecting quality of life in patients with coronary heart disease
(2009)
Amaç: Günümüzde tüm dünyada kardiyovasküler hastalıklar en sık ölüm nedenidir ve yaşam kalitesinde ciddi azalmaya yol açmaktadır. Bu çalışmada ülkemizde, koroner arter hastalarında yaşam kalitesi ve yaşam kalitesini etkileyen ...
Evaluation of cerebellar asymmetry in Alzheimer's disease: A stereological study
(Karger, 2009)
Objectives: Alzheimer's disease (AD) is the most common cause of dementia and, as previous studies have indicated, degenerative changes in the cerebellum occur in AD. It is well known that the cerebellum does not have a ...
Effects of organic and synthetic carotenoids on the sensory quality and chemical composition of rainbow trout (Oncorhynchus mykiss, W. 1792)
(2009)
The chemical qualities and sensory properties of rainbow trout given diets containing red pepper (Oleoresin paprika) extract, gammarus powder, commercial astaxanthin and canthaxanthin over a 2 month period were compared ...
The relationship between plasma homocysteine and early coronary collateral vessel development after acute myocardial infarction
(2009)
Amaç: Homosisteinin endotelyal hücre proliferasyonunu inhibe ettiği bilinmektedir. Koroner kollateral dolaşımın gelişimini etkileyen faktörler iyi bilinmemektedir. Bu çalışmada plazma homosistein düzeylerinin akut miyokard ...
Influence of annealing temperature on the microstructure and mechanical properties of MgB2
(Institute of Physics Publishing, 2009)
We have investigated the effect of annealing temperature on the microstructure, magnetic and mechanical properties of MgB2 superconducting samples employing X-ray diffraction (XRD), scanning electron microscopy (SEM), ac ...
Family of surface with a common null geodesic
(2009)
We analyzed the problem of finding a surfaces family through a null curve with Cartan frame. We constructed a differential equation system such that a given null curve is an isogeodesic curve on a surface. In addition, ...
Bathymetric distribution, seasonal growth and mortality of the deep-water rose shrimp parapenaeus longirostris (Decapoda: Penaeidae) in an unexploited stock in Saros Bay, Aegean Sea
(2009)
To describe the growth, mortality and distribution pattern of the deep-water rose shrimp, Parapenaeus longirostris in an unexploited resource, 301 trawl surveys were conducted between 20 and 465 m water depths from February ...
