A 68-year-old woman exhibited an increasingly protruding mass on the left heart border on chest X-ray. Transthoracic echocardiography revealed an echo-free mass in the anterior pericardial space. Transesophageal echocardiography revealed blood flow from the proximal left anterior descending coronary into a large coronary artery aneurysm measuring 61 mm × 51 mm in diameter and a quadricuspid aor...

The aim of our study is to present a very rare accessory middle scalene muscle, leading to thoracic outlet syndrome. In particular, a muscular bundle was discovered on a male cadaver connecting the middle portion of the middle scalene muscle with the anterior scalene muscle insertion to Lisfranc's tubercle. This triangular accessory muscle and, especially, its sharp medial border compressed the...

During the development of multicellular organisms, various types of directed cell migration occur that contribute to the development of different tissues. These include the migration of neural crest cells, hematopoietic stem cells and germ cells. Gaining a better understanding of the mechanisms that govern normal cell motility and invasion is crucial for understanding development but may also c...

Introduction: The effect of education on esthetic perception is still unclear. This study aims to compare the perception of smile esthetics, under various conditions, among general and specialist dentists. Materials and Methods: A photograph of a woman’s smile was digitally altered using a software image editing program. Alterations were made tothe dental midline, anterior gingival displ...

Introduction The brachial plexus is a complex structure which is divided into roots, trunks, divisions and cords. The brachial plexus is formed by the union of ventral rami of C5, C6, C7, C8 and greater part of T1.These ventral rami are the roots of brachial plexus, almost equal in size but variable in their mode of junction. Ventral rami of C5 and C6 unite at the lateral border of the scalenus...

PURPOSE Many studies have been conducted to date regarding whether the right hepatic vein is the accurate border that divides the anterior and posterior section of the right liver. It has been reported that the Glisson pedicle of the right liver may be an anatomical variation that does not have a consistent morphology. We analyzed the relationship between the true borders of the anterior and po...

It was previously shown that a small lesion in the primary somatosensory cortex (S1) prevented both cortical plasticity and sensory learning in the adult mouse visual system: While 3-month-old control mice continued to show ocular dominance (OD) plasticity in their primary visual cortex (V1) after monocular deprivation (MD), age-matched mice with a small photothrombotically induced (PT) stroke ...

BACKGROUND Previous work has shown the importance of restoring the normal structure of the native meniscus with meniscal allograft transplantation. PURPOSE/HYPOTHESIS The purpose of this study was to compare the anatomic positions of the anterior horn and posterior horn between the preoperative medial meniscus and the postoperative meniscal allograft after medial meniscal allograft transplant...

The incisive papilla provides a reference point on the edentulous cast that may be helpful in determining the anteroposterior position of the artificial incisors. The results of the study suggest that the labial surface of the maxillary incisors should be 12 to 13 mm from the posterior border of the incisive papilla. This measurement was significantly smaller in the sample of dentures examined,...

Oileus gasparilomisp. n. is described from nine specimens from the mountains of Quiché in Guatemala, from cloud forest at 1795 m elevation. This represents the second species of the genus for Guatemala, differing from the closely related Mexican species Oileus rimator (Truqui) in having a straight anterior clypeal border, the postocular sulcus divided by a keel and the pronotum almost straight ...
