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 ...
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 ...
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 ...
Effect of dietary vitamin E on the sperm quality of rainbow trout (Onchorynchus mykiss)
(Wiley, 2008)
Vitamin E is a fat-soluble vitamin that consists of a group of tocopherols and tocotrienols with a hydrophobic character. It has a major function in its action as a lipid antioxidant to protect the polyunsaturated membrane ...
Investigation of beaches suitable for nourishment in Rize Province, Turkey
(Middle East Technical University, 2009)
Black Sea Coast Motorway was recently built along the shore (about 600 km), and a number of beaches were destroyed. Now there are a couple of short beaches in Eastern Black Sea region. People need new beaches. On the other ...
Chronic subdural hygroma with thrombocythemia: First case report
(2009)
Subdural hygroma is a frequent delayed complication of head trauma. It is a rare form of bleeding. Most hygromas are clinically silent and a few cases have shown slow deterioration in the chronic stage. We report a case ...
Synthesis of 1,2,4-Triazole derivatives and determination of protonation constant
(2009)
A microwave irradiation method has been developed for the synhesis of some 1,2,4-triazole derivatives using environmentally benign solvent ethanol in open vessels. Twelve 1,2,4-triazole derivatives were synthesized in good ...
Class 1 and class 2 integrons and plasmid-mediated antibiotic resistance in coliforms isolated from ten rivers in northern Turkey
(2009)
We aimed to determine the molecular mechanisms of antibiotic resistance in coliforms isolated from ten rivers in northern region of Turkey. A total of 183 isolates were tested for antimicrobial susceptibility by disk ...
Determination of adsorptive properties of a Turkish Sepiolite for removal of Reactive Blue 15 anionic dye from aqueous solutions
(Elsevier, 2009)
Reactive Blue 15 (RB 15) adsorption on the Turkish Sepiolite was carried out by batch equilibrium technique. IR spectrum and surface area measurement of the composite of dye-sepiolite (Turkish) pointed out that dye species ...
Reversible immobilization of catalase by using a novel bentonite-cysteine (Bent-Cys) microcomposite affinity sorbents
(Elsevier, 2008)
This study focused on developing bentonite-cysteine (Bent-Cys) microcomposite affinity sorbents (38-105 ?m) for catalase adsorption from aqueous solutions. Pseudo-biospecific affinity ligand l-cysteine was covalently binded ...
