CONTEXT Aging changes the biology, healing capacity, and biomechanical function of tendons and ligaments and results in common clinical pathologies that present to orthopedic surgeons, primary care physicians, physical therapists, and athletic trainers. A better understanding of the age-related changes in these connective tissues will allow better patient care. EVIDENCE ACQUISITION The PubMed...

While there are many reasons to continue to smoke in spite of its consequences for health, the concern that many smoke because they misperceive the risks of smoking remains a focus of public discussion and motivates tobacco control policies and litigation. In this paper we investigate the relative accuracy of mature smokers' risk perceptions about future survival, and a range of morbidities and...

ABSTRACT The study of magnetism in stars close to the transition from fossil dynamo magnetic fields is important for understanding nature stellar and dynamics outer atmosphere. We present surface maps two that are located on opposite sides suspected zone: chemically peculiar late A-star β Coronae Borealis (A9SrEuCr) early F-star σ Bootis (F3V). large-scale field reconstructed at six epochs show...

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...
