background: colorectal cancer is the second cause of the cancer related mortalities in the world. screening can effectively reduce the mortality and morbidity rate of this cancer. sensitivity and specificity of screening methods play an important role in their efficacy. the aim of this study is to review sensitivity and specificity of selected colorectal cancer screening methods systematically....

BACKGROUND AND AIM: Various measurement devices are available for detection of halitosis. For epidemiologic studies, it is necessary to use a portable and small device. This study aimed to investigation of correlation between measuring the device (Etiquette checker) with Halimeter. METHODS: One hundred volunteers (students and patients) participated in this study. The amount of volatile sulfur ...

There  has  been  considerable  debate  over  what  the  sources  of  morphological  variation  in  second  language acquisition  are.  From  among  various  hypotheses  put  forth  on  the  topic,  the  feature  reassembly  hypothesis (Lardiere, 2005) assumes that it is the reconfiguration of features in the L2 which causes variation between the performance of natives and non-natives. Acknowle...

Cytarabine is the drug of choice for treatment of leukemia. However, many formulations have been prepared, due to certain limitations they could not prove to be effective ones, therefore magnetic microspheres are formulated as they minimize the Reticuloendothelial clearance and target site specificity can be increased. The current study aimed to utilize nanotechnology to develop magnetic micros...

Background: Different immunological methods are used for the serodiagnosis of Fasciola hepatica infections, however, they have limited specificity and/or sensitivity.Objective: To improve the specificity of ELISA using a partially modified method for preparation of excretory-secretory (ES) antigens.Methods: Studied groups were as follows: 75 patients with parasitological evidence of fascioliasi...

Scientimammography (SMM) is a new non-invasive method of imaging breast tumors which in various studies the overall sensitivity of 83%-95.8% and specificity of 52%-95% is reported. The purpose of our study was to evaluate the usefullness of 99mTc-MIBI SMM in our environment in detecting breast cancer and in reducing the rate of biopsy. 65 patients aged 23-70 years were included in this st...
