Verbascum tuna-ekimii (Scrophulariaceae), a new species from Turkey
(Finnish Zoological Botanical Publishing Board, 2004)
Verbascum tuna-ekimii Karaveliogullari, Duran & Hamzaoglu sp. nova (sect. Bothrosperma) is described from E Anatolia in Turkey. It is related to and compared with V. laetum, from which it mainly differs in its leaves, ...
A new species of Scorzonera (Asteraceae) from South Anatolia, Turkey
(Versita, 2004)
Scorzoncra yildirimlii A. DURAN et HAMZAOGLU sp. nov. from southwestern Turkey is described and illustrated. It is related to S. pygmaea SIBTH. & SM. and S. rigida AUCHER, from which it mainly differs in its habitus, leaves, ...
New syntaxa from the west part of Central Anatolia
(Pakistan Botanical Soc, 2004)
Three plant communities in Central Anatolia are named, classified and briefly described. All the associations in the study area were attached to a new suballiance: Ebeno hirsutae-Thymenion leucostomi in the alliance ...
Covalent immobilization of invertase on microporous pHEMA-GMA membrane
(Elsevier Sci Ltd, 2004)
Poly (2-hydroxyethyl methacrylate-glycidyl methacrylate) (pHEMA-GMA) membrane was prepared by UV-initiated photopolymerization. Invertase was immobilized by the condensation reaction of the epoxy groups of glycidyl ...
Poly(styrene-hydroxyethyl methacrylate) monodisperse microspheres as specific sorbent in dye affinity adsorption of albumin
(Taylor & Francis Inc, 2004)
In this study, human serum albumin (HSA) adsorption properties of reactive green HE-4BD-attached monodisperse poly(styrene-2-hydroxyethyl methacrylate) [poly(St-HEMA)] microspheres were investigated. Poly(St-HEMA) microspheres ...
Polyethyleneimine-grafted poly (hydroxyethyl methacrylate-co-glycidyl methacrylate) membranes for reversible glucose oxidase immobilization
(Elsevier Science Sa, 2004)
Glucose oxidase (GOD) was immobilized onto polyethyleneimide (PEI) grafted poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) (poly(HEMA-co-GMA)) membranes. The maximum GOD immobilization capacities of the ...
The chordae tendineae of the heart in chicken
(Blackwell Verlag Gmbh, 2004)
In this study, the chordae tendineae of 10 adult chickens have been investigated by means of scanning electron microscopy (SEM). It has been observed that the diameter of the collagen fibrils on the left side of the heart ...
Surface properties of Reactive Yellow 2 immobilised pHEMA and HEMA/chitosan membranes: characterisation of their selectivity to different proteins
(Elsevier, 2004)
Poly(hydroxyethyl methacrylate), pHEMA, and a composite pHEMA/chitosan networks were synthesized in the membrane form via UV initiated photo-polymerisation in the presence of an initiator alpha,alpha'-azoisobutyronitrile. ...
Evaluation of lysozyme adsorptive behaviour of pHEMA-based affinity membranes related to the surface energy and its components to be used in chromatographic fields
(Elsevier, 2004)
We have studied the influence of the surface energy and its components of two different dye-ligand immobilised poly(hydroxyethylmethacrylate) (pHEMA) membranes to the adsorption of a protein "lysozyme" from aqueous solutions. ...
Preparation and characterisation of surfaces properties of poly(hydroxyethylmethacrylate-co-methacrylolyamido-histidine) membranes: application for purification of human immunoglobulin G
(Elsevier, 2004)
In this study, an affinity membrane containing L-histidine as an amino acid ligand was used in separation and purification of human immunoglobulin G (HIgG) from solution and human serum. The polarities and the surface free ...
