Intrapulmonary teratoma is reported in a 22-year-old male. A chest X-ray in a physical examination showed a round shadow in the left hilum of a 22-year-old man who, on admission, reported slight malaise and a decrease in body weight. Computed tomographic scan and magnetic resonance imaging of the chest showed a heterogeneously dense cystic lesion. The preoperative diagnosis was anterior mediast...

Many organizations provide information technology services, either to external or internal customers. They maintain software, operate information systems, manage and maintain workstations, networks or mainframes or provide contingency services. A widely used framework on IT service quality (at least in the Netherlands) is the Information Technology Infrastructure Library (ITIL), which seeks to ...

The purpose of this study was to evaluate the histologic response after replantation of mature, developed teeth without endodontic treatment in monkeys. To serve as experimental controls, the other replanted teeth received endodontic treatment. No significant differences were noted in the rate and quality of periodontal tissues healing between the endodonticall and the nonendodontically treafed...

Over the past 30 years, numerical methods and simulation tools for fluid dynamic problems have advanced as a new discipline, namely, computational fluid dynamics (CFD). Although a wide spectrum of flow regimes are encountered in many areas of science and engineering, simulation of compressible flow has been the major driver for developing computational algorithms and tools. This is probably due...

The death stops here lants rely on a sensitive process of programmed cell death to curtail pathogenic infection by selectively executing infected cells. To prevent the death response from spreading to noninfected areas, cells near and at the site of infection activate autophagy, say and colleagues. In virus-infected plants that are unable to turn on autophagy, cell death spreads from the site o...

Teratomas are rare germline tumors that originate from one or more embryonic germ cell layers. Teratoma of the kidney is extremely rare, and less than 30 cases of primary intrarenal teratomas have been published to date. We report the main radiologic features of an unusual case of mature cystic teratoma arising from the left kidney in a two-year-old boy. A left-sided abdominal mass was detected...

CONTEXT The mature athlete's shoulder remains a challenging clinical condition to manage. A normal natural history of the shoulder includes stiffness, rotator cuff tears, and osteoarthritis, all of which can become increasingly more symptomatic as an athlete ages. EVIDENCE ACQUISITION PubMed (1978-2013). STUDY DESIGN Clinical review. LEVEL OF EVIDENCE Level 3-4. RESULTS Rotator cuff pat...
