The Di-π-methane Photorearrangement of 2,3-Disubstituted Benzobarrelenes and Benzonorbornadiene − Substituent Effects in Regioselectivity
(Wiley-V C H Verlag Gmbh, 2002)
2,3-Disubstituted benzobarrelene and benzonorbornadiene derivatives 16, 17, and 18, containing electron-withdrawing and electron-donating substituents, have been synthesized and subjected to triplet-sensitized photoisomerization. ...
Prognostic implications of microscopic proximal bronchial extension in non-small cell lung cancer
(Elsevier Science Inc, 2002)
Background. The loss of approximately one third of early stage lung cancer patients undergoing complete resection by the end of 5 years implies the existence of unknown or undetected factors at the time of operation. We ...
Neopterin levels in nonreplicative HBV carriers
(Elsevier Sci Ireland Ltd, 2002)
The aim of this study was to determine the existence of immune activation by measuring neopterin in HBV (Hepatitis B virus) carriers with viral load (HBV DNA) less than 5 pg/ml. Forty-three subjects and 56 healthy controls ...
The reliability of grading the fixation preference test for the assessment of interocular visual acuity differences in patients with strabismus
(Mosby-Elsevier, 2002)
Purpose: The purpose of this study is to test the reliability of the grading system of standard fixation preference testing compared with the logarithmic scale of the minimum angle of resolution (logMAR) interocular visual ...
Separation of human-immunoglobulin-G from human plasma with L-histidine immobilized pseudo-specific bioaffinity adsorbents
(Marcel Dekker Inc, 2002)
The pseudo-biospecific affinity ligand L-histidine immobilized poly(2-hydroxyethylmethacrylate) (PHEMA) in spherical form (100-150 mum in diameter) was used for the affinity chromatographic separation of human-immunoglobulin-G ...
The effect of electric and magnetic fields on the operation of a photovoltaic cell
(Elsevier Science Bv, 2002)
In this work, we have investigated the effects of electric and magnetic fields on the operation of a CdS/CuInSe2 photovoltaic cell. Various electric field intensities changing from 0 to 35000 V-dc/m, were applied to the ...
The prevalence, colonization sites and pathological effects of gastric helicobacters in dogs
(Scientific Technical Research Council Turkey, 2002)
The prevalence and colonization sites of Helicobacter slap. in the stomachs of dogs, and their association with gastric pathology were investigated. Scraping cytology, culture, urease test and histology were used to detect ...
Cadmium and mercury uptake by immobilized Pleurotus sapidus
(Scientific Technical Research Council Turkey, 2002)
Pleurotus sapidus basidiospores immobilized onto Ca-alginate beads were used for the removal of cadmium and mercury ions from aqueous solutions. The biosorption of Cd(II) and Hg(II) ions on the alginate beads and both ...
Intestinal ischemia-reperfusion and plasma enzyme levels
(Springer-Verlag, 2002)
Determination of blood levels of intracellular enzymes is an appropriate method to evaluate tissue an organ damage. To show systemic tissue damage resulting from intestinal ischemia-reperfusion, New Zealand rabbits underwent ...
