DSM-IV Combined Type ADHD Shows Familial Association With Sibling Trait Scores
2008
Contains fulltext : 69060.pdf (Publisher’s version ) (Closed access) Attention deficit hyperactivity disorder (ADHD) is a discrete clinical syndrome characterized by the triad of inattention, hyperactivity, and impulsivity in the context of marked impairments. Molecular genetic studies have been successful in identifying genetic variants associated with ADHD, particularly with DSM-IV inattentive and combined subtypes. Quantitative trait locus (QTL) approaches to linkage and association mapping have yet to be widely used in ADHD research, although twin studies investigating individual differences suggest that genetic liability for ADHD is continuously distributed throughout the population, u…
Decrease in Serum Vitamin D Level of Older Patients with Fatigue
2019
Fatigue is characterized by reduced energy level, decreased muscle strength, and a variable degree of cognitive impairment. Recent evidences seem to link vitamin D deficiency to fatigue. The aim of this study was to assess and compare vitamin D status in a cohort of older subjects with and without fatigue. We recruited a total of 480 subjects, 240 patients with fatigue and 240 controls without fatigue, from the Cannizzaro Hospital of Catania (Italy). Fatigue severity was measured by the fatigue severity scale, whereas mental and physical fatigue were measured through the Wessely and Powell fatigue scale, respectively. We also measured several blood parameters and 25-OH vitamin D. Subjects w…
The heritability of depressive symptoms: multiple informants and multiple measures
2002
Background: Earlier research suggests large rater differences in heritability estimates of children's depressive symptoms in the context of significant age and sex-limitation effects. Methods: With data from an ongoing, population-based twin-family study, we estimated genetic and environmental influences on children's depression with models allowing for sex-specific effects. Our assessments of twins included self-reports and ratings made by their classmate peers, their parents and their teachers, allowing estimates of genetic and environmental effects with data from different informants. Model-fitting used maximum likelihood estimation of log-transformed data from a sample of 1,366 11- and …
Long-term outcomes in men and women with ST-segment elevation myocardial infarction and incomplete reperfusion after a primary percutaneous coronary …
2019
Background The failure of reperfusion therapy in patients with ST-segment elevation myocardial infarction (STEMI) is more frequent than considered previously. Aim To evaluate sex-related differences in long-term outcomes in patients with STEMI and incomplete infarct-related artery reperfusion after a primary percutaneous coronary intervention. Patients and methods Of consecutive 42 752 patients with STEMI hospitalized between 2009 and 2011 in Poland, we analyzed a group of 766 (35%) women and 1453 (65%) men with less than thrombolysis in myocardial infarction (TIMI) flow grade 3 following a primary percutaneous coronary intervention. Results In the 2-year follow-up, the mortality rate among…
Development and Validation of the Questionnaire of Academic Stress in Secondary Education: Structure, Reliability and Nomological Validity
2018
This study presents the validation process of the Questionnaire on Academic Stress in Secondary Education (QASSE) designed to assess the wide variety of school sources and situations related to academic stress in adolescence, and their relationship with students&rsquo
Gender, self-confidence, sports, and preferences for competition
2016
In the last years, research in economics has shown a gender gap in the willingness to compete with women shying away from competition more than men do. This gender difference in preferences towards competition has been considered a critical factor in explaining the small percentage of women found in top-level positions in business, science, or politics. Therefore, in order to improve women job prospects, research and policy interventions try to offer incentives for women to increase competitive behavior. However, other recent studies specifically point at men¿s competitive behavior as the responsible for some of the financial markets malfunctions, suggesting that an influx of talented women…
Real Time Stereo Matching Using Two Step Zero-Mean SAD and Dynamic Programing
2018
Dense depth map extraction is a dynamic research field in a computer vision that tries to recover three-dimensional information from a stereo image pair. A large variety of algorithms has been developed. The local methods based on block matching that are prevalent due to the linear computational complexity and easy implementation. This local cost is used on global methods as graph cut and dynamic programming in order to reduce sensitivity to local to occlusion and uniform texture. This paper proposes a new method for matching images based on a two-stage of block matching as local cost function and dynamic programming as energy optimization approach. In our work introduce the two stage of th…
Brief maternal separation procedures occurring early in life affect learning and memory in adult Wistar rats: sex-related differences in cognitive be…
2015
Adverse life events during the neonatal period result in long-term effects on physiology and behavior. Early postnatal experiences, such as a modification of the mother–infant interaction, may influence the development of neural systems that underlie the expression of neuroendocrine and behavioural responses to environmental challenges. The present study was carried out to investigate the consequences of a brief, maternal separation on declarative and spatial memory, focusing on sex related alteration due to the discrete effects that hormones may play on the brain circuits. Our results indicate that a brief, daily maternal separation results in sexually-dimorphic cognitive alterations that …
Class-attendance and Online-tests Results: Reflections for Continuous Assessment
2020
Sometimes class-attendance is a component (or requirement) to benefit from the continuous assessment. The objective of this study is to evidence that some students seem to be getting unfairly penal...
An analysis of the different patterns of 1:1 interactions between educational professionals and their students with varying abilities in inclusive cl…
2012
The purpose of this study was to examine the different types and patterns of 1:1 interactions provided by general educators, special educators and paraprofessionals to children with mild disabilities (n = 13), severe disabilities (n = 13), and children without disabilities (n = 13) in inclusive classrooms. General educators, special educators, and paraprofessionals' 1:1 interactions with students in three comparison groups were recorded in 17 elementary and middle school classrooms using a partial interval observation system. We found significant differences with respect to interaction frequency and content. Teachers and paraprofessionals had consistently more 1:1 interactions with students…
