(Elsevier Science Bv, 2003)
The effective removal of toxic heavy metals from environmental samples still remains a major topic of present research. Metal-chelating membranes are very promising materials as adsorbents when compared with conventional ...
Restoration of the eutrophic Lake Eymir, Turkey, by biomanipulation after a major external nutrient control I
(Springer, 2003)
Nutrient loading in lakes is recognized as a serious threat to water quality. Over 25 years of raw sewage effluent discharge shifted Lake Eymir from a state dominated by submerged plants to a turbid water state. Successful ...
Resistance index in fetal interlobar renal artery with renal pelvic dilatation up to 10 MM
(John Wiley & Sons Inc, 2003)
Purpose. The purpose of this study was to compare the resistance indices (RIs) in the fetal interlobar renal arteries (IRAs) of third-trimester fetuses with or without pelvicaliceal dilatation of up to 10 mm and to compare ...
Detection of telomerase activity in bronchial lavage as an adjunct to cytological diagnosis in lung cancer
(Elsevier Science Bv, 2003)
Objective: Definitive diagnosis of lung cancer with conventional methods may sometimes be difficult in clinical practice. Telomerase is a ribonucleoprotein DNA polymerase that maintains the telomeric region of chromosomes ...
Covalent immobilisation of invertase onto a reactive film composed of 2-hydroxyethyl methacrylate and glycidyl methacrylate: properties and application in a continuous flow system
(Elsevier Science Sa, 2003)
Invertase was covalently immobilised on the poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) (poly(HEMA-GMA)) film. The invertase immobilisation capacity of the films was increased as the GMA ratio increased in the ...

Muscle herniation can be defined as protrusion of a portion of muscle through an acquired or congenital defect of enclosing fascia. Although it is usually a cosmetic problem, it can lead to local pain and tenderness after ...
Effects of NaOCl on bond strengths of resin cements to root canal dentin
(Lippincott Williams & Wilkins, 2003)
Microleakage occurs due to the lack of sealing ability of root sealing materials or adhesive cements used to lute post-core materials. This may cause premature failure of endodontic treatment. The purpose of this study was ...
