background: toxoplasmosis is a zoonotic disease with widespread distribution throughout the world. it is caused by the pro­tozoan parasite toxoplasma gondii . as laboratory diagnosis of toxoplasmosis is not straightforward, this study was aimed to compare the sensitivity and specificity of conventional and unconventional methods of diagnosis based on the meas­urement of igm and igg for determin...

conclusions pivka-ii was as efficient as afp when used as a single marker for hcc screening and the combination of two biomarkers gave a better performance. results the sensitivity and specificity of pivka-ii were 74.6% and 67.8% at a cutoff of 40 mau/ml and 64.2% and 89.7% at a cutoff of 200 mau/ml. the sensitivity and specificity of afp were 76.7% and 65.0% at a cutoff of 20 ng/ml and 60.4% a...

seasonal variations of climatic parameters are significant in arid and semi-arid regions and sensitivity of each parameter may differ in different seasons. no work has been done in this regard in iran. therefore, in this study, sensitivity analysis of the asce-penman-monteith grass reference evapotranspiration (eto) equation was investigated on the basis of variation of mean air temperature (tm...

background enterococci are a natural part of the genito-intestinal and gastrointestinal normal flora in humans and are widely distributed in the environment and are one of the most important causes of nosocomial infections. conclusions in this study none of the isolates were resistant to vancomycin, while 20% of isolates with mic of 4 μg ml-1 had intermediate reaction to it. other demographic p...

Contrast sensitivity functions (CSFs) were measured in the foveal region while subjects simultaneously performed an instantaneous judgment task, which was designed to maintain their attended areas at a constant size. Spatial attention was sustained over areas that were either narrow (Narrow condition) or broad (Broad condition). We observed that the sensitivity at higher frequencies (over 3 cpd...

187 commercial checken flocks affected with respiratory diseases were examined for ornithobacterium rhinotracheale isolation. the bacterium was isolated from 105 (56.2%) poultry flocks. drug sensitivity test using standard disk diffusion technique was performed with 19 antibiotics. all the isolates were susceptible to tiamulin and most of them were susceptible to chloramphenicol and linco-spect...

statement of the problem nowadays in many of the dental radiography centers in iran, three types of intraoral films are being used. there is a controversy about the best film regarding to sensitivity properties. purpose in this study, we aimed to compare sensitivity characteristics and detail recording of intraoral films. material and methods in this experimental study, three types of intraoral...

introduction: fao aquacrop model (raes et al., 2009a; steduto et al., 2009) is a user-friendly and practitioner oriented type of model, because it maintains an optimal balance between accuracy, robustness, and simplicity; and it requires a relatively small number of model input parameters. the fao aquacrop model predicts crop productivity, water requirement, and water use efficiency under water...

in this study, a new sign for clinical diagnosis of acute appendicitis is introduced. the study was performed on a sample of 250 cases simply selected from the patients with acute appendicitis admitted to al-zahra hospital of isfahan. before operation, the patients were evaluated for this sign in order to assess its predictive value in diagnosis of acute appendicitis. following the intervention...

mpsiac is currently known as an appropriate method to measure sediment ofwatershed basins of the country while there has not been any sensitivity analysis so far forthis method. in this study, required data for mpsiac model were gathered from six basins;amame-kamarkhani, kand-golandok, tang kenesht (from two different references), nojian(from three different references), pegahe sorkh katvand (f...
