nuchal translucency (nt) measurements in the first trimester screening between 11 and 14 weeks’ gestation are regarded as a clear marker for aneuploidies. the presence of a thickened nt, even if the karyotype is normal, can be associated with structural abnormalities. having an abnormal screening of nt, parents and physicians could face dilemma over abortion particularly in a case of ivf/icsi f...

background and aims: it is well known that dyslipidemia is related to cardiovascular disease, dietary aspect and obesity play an important role in cvd risk factor. in the present study, we investigated the relationship between calorie intake, anthropometrical parameters and serum lipids in apparently healthy women. methods: the subject were 90 healthy women aged between 20-55 who were taken par...

current guidelines suggest that the ppd mantoux tuberculin test should be read after 48 or 72 hours. we have compared the measurements at these time points. a 5-tuberculin unit (tu) ppd mantoux test was administered to 100 subjects (91% with bacillus calmette- guerin scars). induration was measured 48 and 72 hours following the injection. results the measurements made at 72nd hour were signific...

background diagnosis and accuracy in determining the exact location, extent and configuration of bony defects of the jaw are of utmost importance to determine prognosis, treatment planning and long-term preservation of teeth. if relatively accurate diagnosis can be established by radiography, proper treatment planning prior to treatment procedures will be possible. objectives the aim of the pre...

 The existence and non-existence of trend-resistant repeated measurement designs are investigated. Two families of efficient/optimal repeated measurement designs which are very popular among experimenters are shown to be trend-resistant or trend-resistant with respect to treatments.

Background and Objectives: Evaluating the performance of clinical units is critical for effective management of health settings. Certain assessment of clinical variables for performance analysis is not always possible, calling for use of uncertainty theory. This study aimed to develop and evaluate an integrated independent component analysis-fuzzy-data envelopment analysis approach to accurate ...

The use of different optical-fiber sensors for weighing measurements is Abstract described. By using three different mechanical stressing mechanisms, the operation of the fiber-to-fiber transducer systems are tested and the results are presented. Parameters such as sensitivity, hysteresis, resolution, and dynamic range are measured. A comparison of the results has shown that the sensor system m...

In this research, first of all, the existing problems in fragmentation measurement are reviewed for the sake of its fast and reliable evaluation. Then, the available methods used for evaluation of blast results are mentioned. The produced errors especially in recognizing the rock fragments in computer-aided methods, and also, the importance of determination of their sizes in the image analysis ...

background: pain, a common phenomenon in multiple sclerosis (ms) patients, is associated with many symptoms and problems.  to investigation severity and distribution of musculoskeletal pain in ms patients. methods: in this cross-sectional study, 115 members of the mazandaran ms association with confirmed ms were randomly selected to participate in the study. the patients were asked to fill out ...
