Beneficial effects of melatonin on reperfusion injury in rat sciatic nerve
(Blackwell Munksgaard, 2004)
Studies have shown that ischemia-reperfusion (I/R) produces free radicals leading to lipid peroxidation and to damage of the nervous tissue. Melatonin, a main secretory product of the pineal gland, has free radical scavenging ...
The association of bone mineral density with insulin resistance in patients with polycystic ovary syndrome
(Elsevier Science Bv, 2004)
Objective: The aim of the study was to compare the bone mineral density (BMD) measurements between the patients with polycystic ovary syndrome (PCOS) and age and the body mass index (BMI) matched healthy controls, and to ...
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 ...
Effects of moderate smoking on the central visual field
(Wiley, 2004)
Purpose: To investigate whether moderate cigarette smoking has any effects on the central visual field. Methods: This study included 30 healthy, moderate cigarette smokers (10-20 cigarettes per day for at least the past 5 ...
A research on the level of urine neopterin to see if it may provide a vital clue for a provisional diagnosis of breast cancer in menopausal women
(Elsevier Ireland Ltd, 2004)
Objectives: To search the relation between the level of neopterin in urine and breast cancer developed in menopause. Methods: In this study, urine samples were collected from randomly selected menopausal and post-menopausal ...
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 ...
