O desenho da figura humana e o TAT em adolescentes grávidas: um estudo no hospital geral

The adolescent pregnancy is a public health problem and a challenge to Psychology, that could contribute proposing health prevention actions to this population. The present study intended to investigate the psychological functioning of 10 pregnant adolescents through analysis of Human Figure Drawing (HFD) and Thematic Apperception Test (TAT). It was observed a high level of anxiety experienced by the pregnant adolescents verified in tracing, in shading and in the poverty of details, that can lead to the development of problems related to pregnancy and the relationship between the family, the adolescent and the baby. As for the TAT, the stories, in general constructed by the teenagers, were poorly structured with reduced content and a magical happy ending. It was concluded that the HFD and the TAT are discriminating and adequate to evaluate these adolescents’ psychodynamics and allow to indicate supporting preventive actions in this area.

Grouping of countries according to indicators of standard of living

The position of 125 countries is studied on the basis of a collection of 26 basic, health, economic and educational indicators. Multivariate statistical methods were used, including Cluster Analysis, Principal Component Analysis and Multivariate Analysis of Variance. The most discriminating variables were life expectancy the child mortality rate, the mortality rate of children of less than five years of age, the birth and fertility rates and the high-school female matriculation rate. The first principal component was interpreted as a measure of the living standard which made it possible to place the countries in order. Five clusters of countries are suggested.

A label-free electrochemical affisensor for cancer marker detection: the case of HER2

In this paper, we report the development of a sensitive label-free impedimetric biosensor based on the use of affibody as bioreceptor and gold nanostructured screen-printed graphite as a sensor platform for the detection of human epidermal growth factor receptor 2 (HER2). The affisensor is realized by immobilizing a terminal cysteine-modified affibody on gold nanoparticles. The sensor was characterized by electrochemical techniques and scanning electron microscopy (SEM). Furthermore, surface plasmon resonance (SPR) technology was also applied to explore the potential of affibodies as small-molecule discriminating tools. Using optimized experimental conditions, a single-use affisensor showed a good analytical performance for HER2 detection from 0 to 40μg/L. The estimated limit of detection was 6.0μg/L. Finally, the realized affisensor was applied to human serum samples.
