The aim of the study was to evaluate the prevalence of restrictive ventilatory defect and to determine the risk factors in subjects with spirometrically-defined restrictive ventilatory defect. We used the population-based, fourth-2, 3 (2008, 2009) and fifth (2010-2012) Korea National Health and Nutrition Examination Survey (KNHANES) to analyze 15,073 subjects, aged ≥40 yr who underwent spiromet...
UNLABELLED Information on the prognostic value of noninvasive stress imaging techniques in the elderly is relatively scarce. This study assessed the prognostic value of dobutamine stress (99m)Tc-tetrofosmin SPECT for the prediction of mortality and cardiac events in elderly patients. METHODS Clinical information and SPECT results were analyzed for 272 consecutive patients > or = 65 y old (mea...
BACKGROUND Left Bundle Branch Block (LBBB) is a known cause of false positive results in myocardial perfusion studies. We aimed at investigation of correlation between degree of severity of perfusion defect on cardiac Single Photon Emission Computed Tomography (SPECT) and presence of coronary artery disease on angiography in patients with LBBB. STUDY DESIGN This was an analytical study and wa...
a one-month-old male terrier dog was referred in shock status with a history of anorexia, tachypnea, abdominal distention and progressive weight loss. auscultation of right side of the lungs found enhanced respiratory noises. the thorough auscultation of the opposite side of the chest revealed the presence of typical intestinal sounds. cardiac auscultation revealed muffled heart sounds and a di...
چکیده : آرای صادره از دادگاه ها علاوه بر شیوه های عادی از طریق فوق العاده نیز قابل اعتراض و رسیدگی مجدد هستند. در مواقعی که رای دادگاه مخل به حقوق ثالث باشد وی می تواند به ان اعتراض کند. قلمرو شمول اعتراض ثالث به تصمیمات قضایی که از آن به رای تعبیر شده محدود می گردد. ولی در مورد قرارها که به اعدادی و نهایی تفکیک می شوند، چون هیچ رویه ثابت و مشخصی در این زمینه در دادگاهها وجود نداشته و همچنین ا...
Parotid Stafne bone defect is a very rare and infrequent variant, which is located on the buccal or lingual surface of the mandibular ascending ramus. In this paper, a case of parotid Stafne defect, which was incidentally discovered during dental radiographic examination, is reported. This bone defect was observed as a lucent oval-shaped defect on the lingual aspect of the right mandibu...
venturi flumes are measurement structures commonly used in water systems to measure the flow discharge. some of them are not well installed or present some geometrical defects. the objective of this study is to investigate the hydraulic influence of a number of typical wrong installations and geometrical defects of long-throated venturi flumes: significant positive or adverse slopes, humps and ...
graphene sheet including single vacancy, double vacancy and stone-wales with armchair and zigzag structure was simulated using molecular dynamics simulation. the effect of defects on shear’s modulus, shear strength and fracture strain was investigated. results showed that these shear properties reduce when the degrees of all kinds of defects increase. the dangling bond in sv and dv defected gr...
In this work, we resolved several seemingly conflicting experimental observations regarding temperature dependence of oxide breakdown in the context of change of voltage acceleration factors with reducing voltages. It is found that voltage acceleration factor is temperature dependent at a fixed voltage while voltage acceleration factors are temperature independent at a fixed TBD. We unequivocal...
The goal of all prosthetic treatment is to obtain a satisfying functional and esthetical oral status. In a fixed bridge, the pontic frequently give the impression that they rest on the top of the ridge rather than emerge from within the alveolar process & lack marginal gingiva & interdental papillae. Black triangles, which almost always interfere with dentofacial esthetics, are present in the e...
