Patient preparation for FDG PET studies is perhaps more critical and more complex than for any other commonly performed imaging procedure. We report a patient with normal blood glucose level prior to the execution of a PET study in which FDG uptake was virtually zero in internal organs and was very extense in large muscle groups. The patient recognizes ingestion several minutes before the test....

The aim of the present study was to establish the normal range for the radiographic distance between the cemento-enamel junction (CEJ) and the marginal bone level (MBL) in the primary dentition, and to relate this distance to various physiological and pathological factors. 128 children at the ages 7, 8 and 9 years took part in the study. Clinical and radiographic examinations of the mesial and ...

In this paper, we address the problem of producing visible spectrum facial images as we normally see by using thermal infrared images. We apply Canonical Correlation Analysis (CCA) to extract the features, converting a many-to-many mapping between infrared and visible images into a one-to-one mapping approximately. Then we learn the relationship between two feature spaces in which the visible f...

let x1;x2;...;xn have a jointly multivariate exchangeable normal distribution. in this work we investigate another proof of the independence of x and s2 using order statistics. we also assume that (xi ; yi); i =1; 2;...; n; jointly distributed in bivariate normal and establish the independence of the mean and the variance of concomitants of order statistics.

background: leptin is a protein product of obesity gene and is synthesized mainly by adipose tissue. objective: the aim of this study was to determine maternal and neonatal serum leptin levels in term preeclamptic and normal pregnancies. materials and methods: this cross sectional study was performed on 37 preeclamptic and 40 normotensive term pregnant women without other disease. serum level o...
