conclusions the outcome of this study is that the oca has no toxic effect on h9c2 cells. results the results showed that the percentage of survived cells amount of extract dilution ratio (1:4; 1:2; 1) were 80.4%; 79.6%, 77.5% respectively. analysis of statistical test results does not show any significant differences between the optical density of the extract dilutions, and the control group in...

Obesity causes many problems such as cardiovascular and chronic kidney diseases. The aim of this study was to evaluate the efficacy of retinoic acid and atorvastatin co-administration in kidneys protection against high-fat diet induced damage. Twenty-five male Wistar rats (200.00 ± 20.00 g) were divided into five groups: 1) Control (standard diet), 2) High-fat diet (cholesterol 1.00%, 75 days),...

Background: The artificial neural networks (ANNs) are useful in solving nonlinear processes, without the need for mathematical models of the parameters. Since the relationship between the CT numbers and material compositions is not linear, ANN can be used for obtaining tissue density and composition.Objective: The aim of this study is to utilize ANN for determination of the composition and mass...

Introduction: High-energy beams of protons offer significant advantages for the treatment of deepseated local tumors. Their physical depth-dose distribution in tissue is characterized by a small entrance dose and a distinct maximum -Bragg peak- near the end of range with a sharp fall-off at the distal edge. Alongside its advantages there are some point that they need to meticul...

background: thermoluminescence dosimetry is one of the dosimetry procedures used widely as routine and personal dosimeters. in order to extend this kind of dosimeters, dental tissue has been examined and was found promising as a tld dosimeter. materials and methods : in this study, 70 health teeth were collected. the only criterion, which was considered for selection of the teeth, was the healt...

in order to find the susceptibility of the claisen rearrangement and next proton shift reaction of ally) aryl etherto the substiment effects in pan position, the kinetic and the:rmodynamie parameters are calculated at the33 ltp level using 6-3110. b asis set. the calculated activation energies for the rearrangements and protonshift reactions are around 3133 kcaumol and 52.16 kcal/mol, nap.. liv...

BACKGROUND We aimed to quantitatively assess the effect of baseline breast density on the incidence, stage, and mortality, and also the natural course of the disease, considering the sensitivity of mammography to clarify its causal or masking effect. METHODS In total, 15,658 women ages 45 to 59 years from the Kopparberg randomized controlled trial in Sweden were prospectively followed from 19...
