Application of NaOH treated Polyporus versicolor for removal of divalent ions of Group IIB elements from synthetic wastewater
(Elsevier Sci Ltd, 2002)
Three different forms of Polyporus versicolor, i.e. alkali-pretreated, heat-inactivated and active, were used for the removal of the divalent ions of Group JIB elements from aquatic systems. The biosorption of Zn(II), ...
Immunologic abnormalities and surgical experiences in recurrent facial nerve paralysis
(Lippincott Williams & Wilkins, 2002)
Objective: To document immunologic findings in patients with recurrent facial paralysis (RFP) and to compare the results of the surgery with the results of medical treatment. Study Design: Retrospective case review. Setting: ...
Procion Brown MX-5BR attached and Lewis metals ion-immobilized poly(hydroxyethyl methacrylate)/chitosan IPNs membranes: Their lysozyme adsorption equilibria and kinetics characterization
(Pergamon-Elsevier Science Ltd, 2002)
Interpenetration networks (IPNs) in membrane form were synthesized from 2-hydroxyethyl methacrylate (HEMA) and chitosan (pHEMA/chitosan) via UV-initiated photo-polymerization in the presence of an initiator alpha, ...
Membrane with incorporated hydrophobic ligand for hydrophobic interaction with proteins: application to lipase adsorption
(Wiley, 2002)
In this study, phenylalanine as a hydrophobic ligand was covalently attached on a comonomer, methacryloyl chloride. Then, poly(2-hydroxyethyl methacrylate-co-methacrylamido-phenylalanine), poly(HEMA/MAPA), membranes were ...
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 ...
