PURPOSE The purpose of this study was to examine whether or not vaginal elasticity or lack of lubrication is associated with deep or superficial dyspareunia. We investigated gynecological cancer survivors treated with radiation therapy. METHODS In a population-based study with 616 women answering a questionnaire (participation rate 78%) and who were treated with radiotherapy for gynecological...
The purpose of this paper is examines the domestic consumer behavior to income changes, floor coverings price (calculated income elasticity, price elasticity and cross-elasticity), handmade carpets and of carpet by machinery. The results of the models using OLS method in the 1984-2010 shows that Both handmade carpets and carpet by...
Introduction: Hospital is known as an important and the most costly performing unit of health care systems, therefore, economic analysis of this unit is very important Methods: This study designed to estimate hospital production function in Orumieh Medical Sciences University hospital's. for this study 16 hospitals were studied. We used panel data for estimation of mentioned function, data were...
In this study, through the elasticity approach, we tried to evaluate the effects of cash subsidy on poverty reduction. In this regard, after the theoretical arguments about the poverty elasticity to income, Gini Coefficient, and price using the data related to the expenses and incomes of the 14701 urban households from 1389 to 1390, the quantitative value of these elasticity was measured and fi...
BACKGROUND Restoration of carotid artery patency is one of the most frequently performed operations in vascular surgery. One of the most important problems that occur both short- and long-term after carotid endarterectomy is recurrent stenosis. Despite advances in imaging studies and better knowledge of the mechanisms of atherogenesis, the mechanism of restenosis remains unclear. Patients with ...
BACKGROUND Obstructive jaundice has been reported to influence liver elasticity, independent of liver fibrosis. The aim of our prospective study was to evaluate the changes in liver elasticity, before and after biliary drainage, in patients with obstructive jaundice, and to evaluate the correlation between elasticity measures and serum markers of liver fibrosis. METHODS This is a prospective ...
This paper addresses the influence of boundary conditions and small-scale effect on the free vibration of nano-plates using molecular dynamics (MD) and nonlocal elasticity theory. Based on the MD simulations, Large-scale Atomic/Molecular Massively Parallel Simulator (LAMMPS) is used to obtain fundamental frequencies of single layered graphene sheets (SLGSs) which modeled in this paper as the mo...
OBJECTIVE To define the modulus of elasticity for nasal septum, auricular, upper lateral, and lower lateral cartilages. METHODS Prospective enrollment of sequential patients undergoing septorhinoplasty. Test samples were obtained through routine surgical interventions using atraumatic harvesting techniques. The modulus of elasticity was determined using a customized biomechanical testing devi...
BACKGROUND Decreased elasticity of the aorta is associated with aging and several risk factors of atherosclerosis. The data regarding this phenomenon in patients with familial hypercholesterolemia are rather sparse. OBJECTIVES To evaluate non-invasively the elasticity of the proximal ascending aorta of 51 heterozygous FH patients compared to 42 normal age and gender-matched controls. METHOD...
INTRODUCTION The hysto-morfological composition of the ascending aorta wall gives to the vessel its characteristic elasticity/distensibility, which is deteriorated due to both physiological (age) and pathological events (hypertension, diabetes, dyslipidemia). This contributes to reduce the wall elasticity and to occurrence of cardiovascular events. MATERIALS AND METHODS Thirty young healthy s...
