results in patients with high breast densities, malignant cases (61.2%) were significantly more in comparison to patients with low breast densities (37.3%) (p= 0.007, or=2.66 95% ci=1.29-5.49). after adjusting for age, density was associated with malignancy in age groups <46 years (p=0.007), and 46-60 years (p=0.024) but not in age group >60yrs (p=0.559). adjusting for menopausal status, densit...

Background: &nbsp;In this study a series of basic dosimetric properties of a low-density (LD) gel dosimeter are investigated. The dose response is studied regarding to linearity, sensitivity, dose-rate and energy dependence as well as lung tissue equivalence. Materials and Methods: The LD gel was made by mixing the polymer gel with expanded polystyrene spheres. Energy dependence was studied...

Injuries in cervical spine X-ray images are often missed by emergency physicians. Many of these missing injuries cause further complications. Automated analysis of the images has the potential to reduce the chance of missing injuries. Towards this goal, this paper proposes an automatic localization of the spinal column in cervical spine X-ray images. The framework employs a random classificatio...

the affinity of low density lipoprotein(ldl) to its receptor is very important, because most of ldl-uptake pathway is done by the ldl receptor and the change in size of ldl particle and the modification in its components may affect the ldl affinity for its receptor. in this study, the effects of a powerful lipid-soluble antioxidant “ubiquinol-10” have been investigated on the affinity of ldl to...

Objective This study was carried out to analyze the effect of varying kilovoltage peak (kVp) on Hounsfield unit (HU) for various tissue substitutes in two different phantoms and their dosimetric impact dose calculation Monaco treatment planning system version 5.11.02. Methods HU density materials obtained from computed tomography images acquired at kVps (80, 100, 120). Two (CatPhan 503 CIRS 062...

normal 0 false false false en-us x-none ar-sa background: adipose tissue as an endocrine organ secretes adiponectin that is a cardiovascular atherosclerosis-modulating factor. however, some studies showed that adiponectin reduces obesity. in the present study, adiponectin association with body mass index (bmi), waist circumference (wc), visceral adipose tissue (vat) and subcutaneous visceral ti...

tissue engineering based on the adipose derived stem cells  promote a strong strategy to propagation of bone, cartilage and fat tissues in the three-dimensional scaffolds, fabricated by combining biological materials with suitable and appropriate growth factors.  in this study, a peo scaffold was used to show that mesenchymal stem cells can attach well; the aim of this study was the investigati...

This study investigates the phenotypic and genetic relationships among bone-density-related traits and those of adipose tissue and plasma lipids in mice with diet-induced atherosclerosis. Sixteen-month-old female F2 progeny of a C57BL/6J and DBA/2J intercross, which had received an atherogenic diet for 4 mo, were examined for multiple measures of femoral bone mass, density, and biomechanical pr...
