Duckworth and Seligman's seminal work found that self-discipline (self-control) was more salient for academic achievement than intelligence. Very little replication work exists, including in different cultures; the current study addressed these gaps. Data were collected from 6th and 7th grade cohorts of early adolescents (N = 589; age: Mean = 12.34 years, and SD = 0.89; 58% female) over two years. The study tested whether self-control was a stronger predictor than intelligence in explaining academic performance two years later as well as in explaining developmental changes over the course of two years. Path analyses provided evidence that both self-control and intelligence longitudinally predicted teacher-reported academic competence as well as school-reported grades; however, intelligence was a significantly stronger predictor than self-control. In addition, only intelligence predicted developmental changes in each measure of academic performance over time, self-control did not.

Biological experiments involving isolated organs and tissues demand precise temperature monitoring and regulation. An automatic temperature control system was proposed and optimised on real isolated swine hearts and the prototype is described in this work. The traditional Langendorff apparatus consists of a heart holder, a reservoir of perfusion solution flowing to aortic cannula and a heating bath allowing passive heat transfer to the reservoir of perfusion solution. The commercial infrared camera FLIR T62101 was added to this basic set-up and used for very precise monitoring of the temperature kinetic of the organ and connected with an electronic feedback loop, which allowed real-time and precise regulation of heat transfer from the heating bath to the perfusion solution and in turn indirectly to the heart tissue. This provides real time control and active regulation of the myocardial tissue temperature. The infrared camera was tested in several modes and several variants of detection were optimised for ideal measurement of the region of interest of the ex vivo organ. The kinetics of the temperature changes and temperature stability of the tissue were recorded and calibrated by external electronic thermometers (type Pt100, inserted in tissue). The time lapse from the hang-up of the hypo termed organ (30 °C) until optimal warming (37 °C) was less than eight minutes in the final instrument prototype. The final stability of the 37 °C tissue temperature was approved; the temperature fluctuation of left ventricle tissue was characterised as 36.8 ± 0.5 °C. This upgraded traditional instrument could be used in specific preclinical and clinical transplantation and analytical projects in future.

Background: The electronic Xray-Record is the Austrian contribution to the PALANTE project. The Austrian pilot aims to implement a new module into the hospital information system used within the KAGes which includes the summary of the dosage of X-ray examinations in a personal eXray-Record. The main goals are to support the personal health management of the patient and to increase the awareness of patients and physicians for X-ray exposure in healthcare. External access for health professionals and patients will be done via a web portal to provide a comprehensive representation of the X-ray exposure data. Additionally, transparency about radiation doses applied in the context of radiological examinations is provided. Objectives: This paper gives a brief description of the web access to radiology data. In particular, the paper outlines the online representation of exposure doses caused by radiology examinations and identifies the challenges. Methods: In the analysis, the national regulatory frameworks and standards were considered. Literature research and expert discussions were done to figure out the risks of the radiation exposure in the low-dose range. Results: Possibilities for data extraction and data representation were worked out. The architecture of the eXray-Record was designed with consideration of important standards. Conclusion: Access to personal health information empowers patients and increases the control over matters concerning their health. Shared decision making would become possible through intelligent use of the eXray-Record and a bi-directional patient-caregiver communication.

Cytomegalovirus (CMV) is the herpetic virus, which infects 45-100% people worldwide. Many reports suggest that CMV could impair cognitive functions of infected subjects. Here we searched for indices of effects of CMV on infected subjects' intelligence and knowledge. The Intelligence Structure Test I-S-T 2000 R was used to compare IQ of 148 CMV-infected and 135 CMV-free university students. Infected students expressed higher intelligence. Paradoxically, their IQ decreased with decreasing concentration of anti-CMV antibodies, which can be used, statistically, as a proxy of the time passed from the moment of infection in young subjects when the age of subjects is statistically controlled. The paradox of seemingly higher intelligence of CMV infected subjects could be explained by the presence of the subpopulation of about 5-10% CMV-positive individuals in the population of "CMV-negative students". These false negative subjects had probably not only the oldest infections and therefore the lowest concentration of anamnestic antibodies, but also the lowest intelligence among the infected students. Prevalence of CMV infection in all countries is very high, approaching sometimes 90%. Therefore, the total impact of CMV on human intelligence may be large.

BACKGROUND: Maternal diabetes adversely affects fetal cardiovascular system development. Previous studies have reported that the fetuses of mothers with diabetes exhibit both structural and functional changes; nevertheless, prior studies have not examined the association between glucose control and fetal cardiac morphology and performance. Thus, the objective was to determine the association between fetal cardiac morphology and function and maternal glucose control in type 1 diabetes and to compare the differences in measured cardiac parameters between the fetuses of mothers with diabetes and healthy controls. METHODS: In this prospective, longitudinal case-control study - including 62 pregnant women with type 1 diabetes mellitus and 30 healthy pregnant women - fetal cardiac assessment using B-mode, M-mode, and spectral pulsed-wave Doppler was performed in the second and third trimesters. In women with T1DM, glycated hemoglobin and data obtained from glucose sensors - including the percentage of time in, below, and above the range (TIR, TBR, and TAR, respectively), and coefficient of variation (CV) - were analyzed across three time periods: the last menstrual period to 13 (V1), 14-22 (V2), and 23-32 weeks (V3) of gestation. Fetal cardiac indices were compared between groups, and the correlation between glucose control and fetal cardiac indices was assessed. RESULTS: At 28-32 weeks, the fetuses of women with T1DM exhibited increased left ventricular end-diastolic length, relative interventricular septum thickness, right ventricular cardiac output, and pulmonary valve peak systolic velocity compared with healthy controls. At 18-22 weeks, pulmonary and aortic valve diameters, left and right ventricular stroke volumes, and left cardiac output inversely correlated with the CV and glycated hemoglobin levels at V1 and V2. Furthermore, at 28-32 weeks, pulmonary and aortic valve diameters, left ventricular stroke volume, cardiac output, and right/left atrioventricular valve ratio inversely correlated with the TBR at V1, V2, and V3. Moreover, diastolic functional parameters correlated with the TAR and glycated hemoglobin levels, particularly after the first trimester. CONCLUSION: In women with T1DM, maternal hyperglycemia during pregnancy correlates with fetal diastolic function, whereas glucose variability and hypoglycemia inversely correlate with fetal left ventricular systolic function in the second and third trimesters.

Background: In Greek scientific literature, no other studies using emotional intelligence as a personal trait were found. Objective: The aim of this study was to explore the validity and reliability of the Trait Emotional Intelligence Questionnaire - Short Form in a Greek educational context. The internal consistency as well as the levels of emotional intelligence, along with the gender as a factor that differentiates emotional intelligence have also been examined. Methods: The sample of the study consisted of 306 (for exploratory factor analysis) and 415 (for confirmatory factor analysis) students who attended the 7th, 8th, and 9th grades of high school. The selection of the sample was randomly performed. The scale consists of 30 questions and four factors. The statistical analysis of the data included descriptive statistics, exploratory and confirmatory factor analysis, reliability analysis using Cronbach's α and discriminant/convergent validity, and t-test for independent samples. Results: The results of the confirmatory factor analysis demonstrated that the hypothesized model produced a significant χ2 (1026.58), normed fit index (.96) and comparative fit index (.97). The root mean square error of approximation (.78) was also considered to assess the degree extent to which the model of fit of. Composite reliability (≥ .948) and average variance extracted (≥ .751) of all dimensions of the Trait Emotional Intelligence Questionnaire - Short Form demonstrated an acceptable reliability coefficient. Conclusions: From the analysis of the results, we came to the following conclusions. The Trait Emotional Intelligence Questionnaire - Short Form constitutes an instrument credible enough to measure the emotional intelligence of high school male and female students. Gender is a differentiation factor for Total emotional intelligence, Self-control, and Well-being factors.
