INTRODUCTION The objective of this study was to evaluate a new method for superimposition of 3-dimensional (3D) models of growing subjects. METHODS Cone-beam computed tomography scans were taken before and after Class III malocclusion orthopedic treatment with miniplates. Three observers independently constructed 18 3D virtual surface models from cone-beam computed tomography scans of 3 patie...

Congenital dermoid fistulas of the anterior chest regions (CDFACRs) consist of a skin orifice at the anterior border of the sternocleidomastoid muscle with fistulas extending caudally in the subcutaneous tissue near the sternoclavicular joint. We report 2 pediatric CDFACR cases with pathognomonic sonography findings. By using sonography, we could diagnose the fistulas as CDFACRs by focusing on ...

In three eyes which underwent cataract extraction no evidence of senile pseudoexfoliation was found either before, or immediately after, surgery in spite of repeated biomicroscopical examination under full mydriasis. Years later pseudoexfoliative material was found on the anterior hyaloid and on the pupillary border. In another case, wherein the lens was traumatically dislocated and had lain in...

There are contradicting data and reports regarding the position of the mandibular lingula in relation to the mandibular foramen and the mylohyoid groove. The current observation attempts to describe the location of the lingula in relation to the mandibular foramen, and the location of the mylohyoid groove in relation to the lingula and mandibular foramen. Fifty adult black Tanzanian mandibles w...

Epithelial to mesenchymal transitions are prominent features of mammalian gastrulation and neural crest development, and are essential for the proper development of many organs and tissues. Moreover, most cancers derive from epithelial cells, and metastasis involves departure of these cells from their epithelium of origin and invasion of the surrounding tissue. It is known that epithelial to me...

Introduction Subacromial impingement syndrome (SIS) is a general term used to describe a variety of conditions that may act independently or in combination, and manifest as anterior or anterior-lateralsuperior shoulder pain. SIS occurs as a result of pathology of one or more of the structures located within the subacromial space. The pain is associated with a loss of shoulder function, especial...

OBJECTIVE Impaired systolic function in the normally perfused myocardium adjacent to an ischemic region - the functional border zone - is thought to result from mechanical interactions across the perfusion boundary. We investigated how segment orientation and vessel involved affect regional strains in the functional border zone and whether altered stresses associated with a step transition in c...

The marginal mandibular nerve was studied post mortem in 50 human subjects. The nerve was found to be presented by one branch (32%), two branches (40%) and three branches (28%). The relationship of the nerve to the lower border of the mandible was variable: it was either totally above the lower border of the mandible (28%), below the mandible (44%) or in 28% of cases lying above and below it. T...

BACKGROUND The objective of this study was to evaluate the topographic relationship between the morphology of the greater tubercle and the insertion of the tendon of the infraspinatus. MATERIALS AND METHODS First, we defined an impression of the greater tubercle, which has not been recognized in classic textbooks, as the "lateral impression" and then measured the dimensions of the "lateral im...

The effects of intracoronary verapamil and nitroglycerin on collateral blood flow were compared under conditions where coronary perfusion pressure was held constant with a servopump and the systemic effects of the drugs were minimal. Both drugs were infused into 12 anesthetized dogs after occlusion of the left anterior descending coronary artery (LAD) and regional myocardial blood flow (MBF) wa...
