Early diagnosis of invasive pulmonary aspergillosis (IPA) remains difficult due to the variable performance of the tests used. We compared the performance characteristics of Aspergillus lateral flow device (LFD) in bronchoalveolar lavage (BAL) vs. BAL-galactomannan (GM), for the diagnosis of IPA. 311 BAL specimens were prospectively collected from patients who underwent bronchoscopy from Januar...

Hastalar ve Yöntem:Bölümümüzün meme görüntüleme ünitesi arşivinden son 10 yılda ultrasonografi incelemesinde memesinde kompleks kist saptanan ve biyopsi yapılan 61 olgu değerlendirildi. Kalın duvarlı-kalın septalı kistler ve solid bileşen içeren kistler çalışmaya dahil edildi. Hem kistik, hem de solid odak içeren karma tip lezyonlar çalışma dışı tutuldu. Tüm lezyonların ultrasonografi ve varsa ...

this paper describes a methodology for the integration of well logs and a series of grid-based attributes extracted from interpreted seismic data for prediction of porosity distributions. the studied area is located in the southwest iran. before finding a relationship between the target logs and predicted logs from 3d seismic data, we have interpreted the 3d seismic data in the studied area. al...

this paper describes the application of approximate methods to invert airborne magnetic data as well as helicopter-borne frequency domain electromagnetic data in order to retrieve a joint model of magnetic susceptibility and electrical resistivity. the study area located in semnan province of iran consists of an arc-shaped porphyry andesite covered by sedimentary units which may have potential ...

Objective(s) The aim of this study was to evaluate the expressions of two angiogenic immune-markers (CD-31 and VEGF), and one proliferative immune-marker (Ki-67) in oral pyogenic granulomas (PG), hemangiomas (Hem) and inflammatory gingivitis (IG). Materials and Methods Sixty cases of PG, Hem and IG (twenty cases each) were examined. Immunohistochemical (IHC) staining was performed based on r...

The spectrum of vascular tumors ranges from hemangioma (HEM), to epithelioid hemangioendothelioma (EHE) and to angiosarcoma (AS). To the best of our knowledge, the usefulness of F-18 fluorodeoxyglucose positron emission tomography (FDG-PET) for vascular tumors has never been comprehensively studied. The present study investigated the usefulness of FDG-PET for pathologically diagnosed vascular t...

Shear-wave velocity ( ) is an important parameter used for site characterization in geotechnical engineering. However, dispersion curve inversion is challenging for most inversion methods due to its high non-linearity and mix-determined trait. In order to overcome these problems, in this study, a joint inversion strategy is proposed based on the particle swarm optimization (PSO) algorithm. The ...

Gereç ve yöntemler: Çalışmada 21 sol distal femur kırığı modeli kullanıldı. Kemikler 3 eşit gruba ayrıldı. Grup 1 örnekleri distal femur anatomik kilitli plak ile yandan tespit edildi. Grup 2 örnekleri distal femur retrograd İM çivi ile tespit edildi. Grup 3 örnekleri hem distal femur anatomik kilitli plak hem distal femur retrograd İM çivi ile tespit edildi. Mekanik testlerde aksiyel yüklenme ...
