in this study, a sensitive method of dispersive liquid phase microextraction based on ion-pair combined with the flame atomic absorption spectrometry was proposed for the determination of trace ni(ii) using aliquat 336-chloride as ion pair agent. several factors which have effect on the microextraction efficiency of ni(ii), such as ph, extraction and dispersive solvent type and their volume, c...
Objectives: The aim of this study was to determine common and specific factors of anxiety and depressive disorders based on the NEO personality dimensions. Method: Four hundred and thirteen students of Tabriz University (200 males, 213 females) selected by cluster sampling responded to the following questionnaires: NEO Five-Factor Inventory (NEO-FFI), Beck Depression Inventory-II (BDI-II), Anxi...

Background: Angiotensin converting enzyme (ACE) upregulation in stromal cells of joints affected by rheumatoid arthritis may lead to higher tissue angiotensin II that is a vasoconstrictor and mitogen factor. To date, the role of angiotensin II on regulating blood flow in inflamed joints has not been studied. Methods: Acute and chronic joint inflammation was induced in rabbits by intra-articular...
In this paper, the stress intensity factor (SIF) expression for defected butt welds containing undercut and inclined lack of penetration (LOP) subject to far-field tensile stress is derived. Some of the standards such as ISO 5817 and BS EN 25817 have specified allowable limits for the length of the undercut and LOP defects and for the height of the weld. In addition, EN 29692 standard has deter...
breast cancer is the most common cause of cancer-related death in female, after lung cancer. angiogenesis is essential for tumor growth and metastasis; therefore, antiangiogenesis strategies for treatment of cancer are currently an issue of interest. the role of vascular endothelial growth factor that assumed to be most potent angiogenesis factor is ambiguous in breast cancer. this study descri...
purpose: to compare orbscan ii and ultrasonic pachymetry for measurement of central corneal thick-ness (cct) in eyes scheduled for keratorefractive surgery. methods: cct was measured using orbscan ii and then by ultrasonic pachymetry in 100 eyes of 100 patients who were scheduled for excimer laser refractive surgery. paired t-test was used for comparing the results. results: using an acoustic f...
