background: more diagnostic techniques require a better understanding of the forces and stresses developed in the wall of the left ventricle. the aim of this study was to differentiate significant coronary artery disease (cad) patients using a non-invasive quantification of myocardial wall stress in the diastole phase. methods: sixty male subjects with sinus rhythm (30 patients with significant...

background hydatidosis is an infectious disease resulting from the development of the larval form of the parasite echinococcus granulosus in humans. the invasion of the chest wall by echinococcosis is rarely described. methods the current study reported all cases of chest wall hydatidosis treated in the department of cardiothoracic surgery from january 1990 to december 2011. results the mean ag...

dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. these walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. in this research intermediate dual system of steel moment frame was chosen with int...

This study evaluated the increase of the instrumented area and dentin thickness in the mesial and distal aspects of mesial canals of mandibular molars after the use of Gates Glidden (GG), LA Axxess (LA) and Orifice Shaper (OS) instruments. A total of 53 canals from 27 mandibular molars were embedded in resin and divided into 3 groups. The roots were sectioned 3 mm below the cementoenamel juncti...

bronchiolo-alveolar carcinoma with subcutaneous chest wall metastasis is a very rare presentation. a case of 36- year-old male with metastatic subcutaneous chest nodule of bronchiolo-alveolar carcinoma, diagnosed by fine needle aspiration cytology, is reported here. cutaneous metastases are of diagnostic importance because they may be the first manifestation of an undiscovered internal malignan...

introduction: based on the invasive studies it has been shown that factors such as age, the progress of eye disorders, lens fibers compression and the biochemical changes of ocular matrix alter the physical characteristics and elastic properties of eye. in this study, a noninvasive method of estimating human eye elasticityis proposed and its relation with age and gender is evaluated using ultra...

Members of the Eucyclops graeteri species complex are widely distributed in European groundwaters and share some morphocharacters such as: a long aesthetasc on ninth segment female antennula, short or very reduced spinule row ("serra") furcal rami, lateral hairiness 5th thoracic somite strongly reduced, few no hairs distal margin intercoxal sclerite 4th legs pair. All these characters subject t...
