High-concentration tramadol-induced vasodilation in rabbit aorta is mediated by both endothelium-dependent and -independent mechanisms
(SHANGHAI INST MATERIA MEDICA, 2003)
Aim: The mechanism of tramadol-induced vasodilation was investigated using isolated rabbit thoracic aortic rings. Methods: Aortic rings from 8 rabbits were placed in organ bath and precontracted with phenylephrine (10(-5) ...
Umbilical serum insulin-like growth factor 1 (IGF-1) in newborns: Effects of gestational age, postnatal age, and nutrition
(VERLAG HANS HUBER, 2003)
Aim: The aim of this study was to determine the relationship,between nutrition, gestational age, and birth weight, and serum insulin-like growth factor I (IGF-1) levels in newborns, Method: The first study group consisted ...
Paleontology and stratigraphy of upper cretaceous sediments in the Ilgaz region (Cankiri, Turkey)
(KING FAHD UNIV PETROLEUM MINERALS, 2003)
The Odemis Formation crops out around Odemis village to the northwest of the town of Ilgaz (Cankiri, Turkey). The Formation was deposited in neritic environments, and it consists of conglomerate, nodular limestone, sandstone, ...
A study on spherical oil agglomeration of barite suspensions
(ELSEVIER SCIENCE BV, 2003)
In this study, the recovery of barite particles was investigated by using oil agglomeration. For this purpose, effects of operating parameters were investigated and also, zeta potential measurements and Fourier Transform ...
Development of a regression model to forecast ozone concentration in Istanbul City, Turkey
(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2003)
In this study, an air quality model including pollutants (NOx, non methane hydrocyarbons (NMHC)) and meteorological parameters (wind speed, solar radiation, rain, relative humidity and temperature) has been developed for ...
Immobilization of catalase into chemically crosslinked chitosan beads
(ELSEVIER SCIENCE INC, 2003)
Bovine liver catalase was immobilized into chitosan beads prepared in crosslinking solution. Various characteristics of immobilized catalase such as the pH-activity curve, the temperature-activity curve, thermal stability, ...
Intersubband transitions for single, double and triple Si delta-doped GaAs layers
(IOP PUBLISHING LTD, 2003)
The intersubband transitions in single, double and triple Si delta-doped GaAs structures are theoretically studied for different applied electric fields. Electronic properties such as the confining potential, the subband ...
Electronic structure of two coupled Si delta-doped GaAs as dependent on the donor thickness
(SPRINGER-VERLAG, 2003)
For the uniform distribution we have theoretically investigated the influence of donor thickness on two coupled Si delta-doped GaAs structure, at T=0 K. Electronic structure have been calculated by solving the Schrodinger ...
Tilted magnetic field effect on the subbands of a GaAlAs diode with a GaAs quantum well
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2003)
We have calculated the subbands in the GaAs quantum well at the n-side of the junction in a Ga1-xAlxAs diode. We show that the density of carriers confined in the quantum well increases by the increasing magnetic field ...
Antioxidant and antimicrobial activity of the essential oil and methanol extracts of Achillea millefolium subsp millefolium Afan. (Asteraceae)
(ELSEVIER SCI IRELAND LTD, 2003)
The in vitro antimicrobial and antioxidant activities of the essential oil and methanol extracts of Achillea millefolium subsp. millefollium Afan. (Asteraceae) were investigated. GC-MS analysis of the essential oil resulted ...
