OBJECTIVE To analyse the evolution of the frequency of type 2 diabetes (T2D) and its relationship to eating patterns in Mexico from 1961 to 2013, and the Gini coefficient, Human Development Index (HDI) and Gross Domestic Product (GDP). Mexico ranked sixth in world prevalence of diabetes in 2015 with an estimated 11.4 million Mexicans affected. METHOD Using data from the Balance Sheets Food pu...

BACKGROUND The understanding of relative effects of genetics and environmental factors on mandible growth would increase effectiveness of orthodontic therapy and treatment planning. The purpose of this study was to clarify whether the skeletal morphology of mandible is phenotypically alike in two individuals in a pair of young adult monozygotic (MZ) twins. METHODS The 90 twin pairs were class...

PURPOSE To develop a questionnaire (in Spanish) to measure computer-related visual and ocular symptoms (CRVOS). METHODS A pilot questionnaire was created by consulting the literature, clinicians, and video display terminal (VDT) workers. The replies of 636 subjects completing the questionnaire were assessed using the Rasch model and conventional statistics to generate a new scale, designated ...

Most statistics students know that the sample correlation coefficient R is used to estimate the population correlation coefficient ρ. If the pair (X, Y) has a bivariate normal distribution, this would not cause any trouble. However, if the marginals are nonnormal, particularly if they have high skewness and kurtosis, the estimated value from a sample may be quite different from the population c...

introduction. one of the proplems that both medical students and educational programmers are involved in is the importance of basic science materials in comprehention of clinical subjects and student's performance after that. our goal is to measure the correlation coefficient between the cbse and cpse and the predictive validity of cbse for cpie. methods. analytic cross-sectional study was...

introduction: emotional intelligence is a key element that determines the achievement and efficiency of a person so that 80% of the achievement is dependent on it. the current research was carried out to determine the correlation between emotional intelligence and evaluation score of the faculty members of kermanshah university of medical sciences (kums) in 2014.   methods: in this analytical-d...

We introduce two new types of random field. The cross correlation field R(s, t) is the usual sample correlation coefficient for a set of pairs of Gaussian random fields, one sampled at point s ∈ <M , the other sampled at point t ∈ <N . The homologous correlation field is defined as R(t) = R(t, t), that is, the ‘diagonal’ of the cross correlation field restricted to the same location s = t. Alth...

In this study a sensitive, simple and accurate spectrophotometric method was suggested for determination of tamsulosin in bulk powder and pharmaceutical dosage form based on the formation of an ion-pair complex between the drug and bromocresol green in a buffer solution at pH 3.5. The formed yellow color complex was extracted with chloroform and measured at 415 nm. The optimum reaction conditio...

The Web has become the most major information source of our daily activities. In this project, we consider a special information need: finding the instance-attribute information from the Web, and particularly, we focus on the instance domain of person. Examples include the contact information (attribute) and research interests (attribute) of faculty or students (person). Most of such personal i...
