Cytotoxin associated gene A-positive Helicobacter pylori strains in dyspeptic pregnant women
(Elsevier Sci Ireland Ltd, 2004)
Objective: The aim of the present study was to compare the Helicobacter pylori (HP) seropositivity and cytotoxin associated gene A (cagA) status in pregnant women with dyspeptic complaints and pregnant women with no ...
Evaluation of differences between observers and automatic-manual measurements in calculation of Doppler parameters
(Wiley, 2004)
Objective. We aimed to search for differences between observers and automatic and manual measurements in calculations of Doppler parameters. Methods. The middle cerebral artery (MCA), central retinal artery, ophthalmic ...
Performance comparison of CFCs with their substitutes using artificial neural network
(John Wiley & Sons Ltd, 2004)
In order to decrease global pollution due to chlorofluorocarbons (CFCs), the usage of HFC- and HC-based refrigerants and their mixtures are considered instead of CFCs (R12, R22, and R502). This was confirmed by an international ...
Affinity membrane chromatography: relationship of dye-ligand type to surface polarity and their effect on lysozyme separation and purification
(Elsevier, 2004)
Two different dye-ligands, i.e. Procion Brown MX-5BR (RB-10) and Procion Green H-4G (RG-5) were immobilised onto poly(2-hydroxyethylmethacrylate) (pHEMA) membranes. The polarities of the affinity membranes were determined ...
Effect of tamoxifen on serum IL-18, vascular endothelial growth factor and nitric oxide activities in breast carcinoma patients
(Wiley, 2004)
Vascular endothelial growth factor (VEGF) is a multi-functional cytokine that has been suggested to be a major angiogenic factor in breast cancer. Nitric oxide (NO) is a potent biological molecule that partipicates in the ...
A multiobject tracking framework for interactive multimedia applications
(Ieee-Inst Electrical Electronics Engineers Inc, 2004)
Automatic initialization and tracking of multiple people and their body parts is one of the first steps in designing interactive multimedia applications. The key problems in this context are robust detection and tracking ...
Structure of 2-{2-[3-methyl-3-(2,4,6-trimethylphenyl) cyclobutyl]-2-oxoethyl}isoindole-1,3-dione
(Springer/Plenum Publishers, 2004)
2-{2-[3-Methyl- 3-(2,4,6-trimethylphenyl) cyclobutyl]-2-oxoethyl} isoindole-1,3-dione (C-24 H25NO3) was synthesized, and its crystal structure was determined by X-ray crystallographic techniques. The compound crystallizes ...
Effect of bimatoprost on ocular circulation in patients with open-angle glaucoma or ocular hypertension
(Springer, 2004)
Purpose: To study the effect of bimatoprost 0.03% (Lumigan) on ocular hemodynamics in patients with open-angle glaucoma or ocular hypertension. Methods: One randomly selected eye of each of 26 patients with open-angle ...
New natural observer applied to speed-sensorless DC servo and induction motors
(Ieee-Inst Electrical Electronics Engineers Inc, 2004)
A simple observer design technique with parameter adaptation is proposed for bounded-input bounded-output nonlinear systems. In this technique, no feedback is used in the observer but parameter estimations are considered ...
The scanning electron and light microscopic structure of bovine tactile hair
(Blackwell Verlag Gmbh, 2004)
Bovine tactile hairs in skin samples from the lateral side of the upper lip were examined using scanning electron and light microscopy. The root of these hairs has a variable length and is surrounded by a large sinus located ...
