Background: The purpose of this study was to calculate and compare the specificity and sensitivity of impulse oscillometry (IOS) as a new technique in the detection of airways dysfunction by means of a simple pulmonary function test in chemical warfare injured cases suffering from respiratory diseases. Methods: The study was performed prospectively in 100 patients, who complained of dyspnea as ...

There has been recent interest in the application of machine learning techniques to neuroimaging-based diagnosis. These methods promise fully automated, standard PC-based clinical decisions, unbiased by variable radiological expertise. We recently used support vector machines (SVMs) to separate sporadic Alzheimer's disease from normal ageing and from fronto-temporal lobar degeneration (FTLD). I...

Despite progresses in the last decades in the comprehension of specificity, the core questions of how it is encoded in the grammar and how it determines the syntax/semantics interplay remain open. This paper describes a new perspective for tackling these questions based on a fine grained syntax/semantics for noun phrases. The proposed format should be able to account for the variety of specific...

Abstract Background The aim of this study was to evaluate sensitivity and specificity of mediastinal sonography, and compared with CT, in detection of anterior mediastinal neoplasms. Materials and Methods The sonography with convex probes (5.0 and 7.5 MHz) was done prospectively for 34 patients (from 2 to 25 years old) with mediastinal mass. The results were compared with the results of ...

Toxocaracati is one of the most important and widespread of the helminth zoonosis. In the present study, helminthosis due to Toxocaracati in 55 stray cats in Tehran was studied by necropsy. In addition, two different diagnostic methods, including serological and coprological tests, for infection with this parasite were compared. The dot-ELISA assay used Toxocaracati crude antigens to evaluate t...

The recent progress made in the development of electrochemical methods for microRNA (miRNA) detection is presented. This progress is conceived to be largely due to the invention of novel assay methodologies and the use of various bioreagents and nanostructures. These enable a rigorous control over the sensing interface, provide enormous signal amplifications and single-base mismatch specificity...

The introduction of biological control agents to new environments requires host specificity tests to estimate potential non-target impacts of a prospective agent. Currently, the approach is conservative, and is based on physiological host ranges determined under captive rearing conditions, without consideration for ecological factors that may influence realized host range. We use historical dat...

PURPOSE Intraoperative frozen section (FS) is an effective diagnostic test for periprosthetic joint infection (PJI). We evaluated the diagnostic characteristics of single- and multiplex-site intraoperative FS, and evaluated the results of single-site FS combined with those of C-reactive protein (CRP) level and erythrocyte sedimentation rate (ESR) for assessing PJI. METHODS We studied 156 pain...
