The two members of the Staufen family of RNA-binding proteins, Stau1 and Stau2, are present in distinct ribonucleoprotein complexes and associate with different mRNAs. Stau1 is required for protein synthesis-dependent long-term potentiation (L-LTP) in hippocampal pyramidal cells. However, the role of Stau2 in synaptic plasticity remains…

Delayed alternation and object alternation are classic spatial and non-spatial delayed response tasks. We tested 632 middle-aged male veteran twins on variants of these tasks in order to compare test difficulty, measure their inter-correlation, test order effects, and estimate heritabilities (proportion of observed variance due to genetic…

When it first emerged about 50 years ago, genetic counseling focused primarily on prenatal testing to detect genetic conditions. But counseling services have evolved to keep pace with a greater knowledge of genetics and wider application of genetic diagnostic testing. Today, there are several types of genetic counselors, and their expertise covers…

Williams syndrome (WS) is a neurodevelopmental disorder characterized by a distinctive behavioral and cognitive profile, including widespread problems with attention. However, the specific nature of their attentional difficulties, such as inappropriate attentional allocation and/or poor attentional disengagement abilities, has yet to be…

Background: Bioinformatics--the use of computers in biology--is of major and increasing importance to biological sciences and medicine. We conducted a preliminary investigation of the value of bringing practical, university-level bioinformatics education to the school level. We conducted voluntary activities for pupils at two schools in Scotland…

This paper reports on a mixed-model case study of designing and implementing a constructivist teaching intervention about reproduction and physical family resemblance for young children. The objective of the study was to explore whether the ways that preschoolers reason about the resemblance between offspring and parents can be improved with a…

This article argues that the Czech education system is structured to operate in an ethnically homogeneous society. Although the Czech Republic is becoming increasingly heterogeneous, teachers deploy discursive practices of "sameness despite difference" that obscure such growing diversity. This article is grounded in the historical…

Analyzing evolutionary relationships requires that students have a thorough understanding of evidence and of how scientists use evidence to develop these relationships. In this lesson sequence, students work in groups to process many different lines of evidence of evolutionary relationships between ungulates, then construct a scientific argument…

I describe and evaluate a fun and simple role-playing exercise that allows students to actively work through the process of translation. This exercise can easily be completed during a 50-minute class period, with time to review the steps and contemplate complications such as the effects of various types of mutations.

This study investigates the effect of a conceptual change approach over traditional instruction on students' understanding of DNA, gene and chromosome concepts. 52 10th grade students belonging two different classes participated the study. One of the classes was assigned randomly to the control group, and the other class was assigned randomly to…

The treatment and care of persons with a disability should and must be all encompassing. With the expansion of the knowledge that proper dieting can make a difference in the individual's development and quality of life, attention must be focused on using proper food intake to remediate the negative impact of a disability. Food is related to proper…

This exploratory longitudinal study examined behavioral outcomes and parenting stress among families with children adopted from foster care, taking into account environmental and biological risk factors. Child internalizing and externalizing problems and parenting stress were assessed in 82 adopted children and their families at 2 months…

The home literacy environment is a well-established predictor of children's language and literacy development. We investigated whether formal, informal, and indirect measures of the home literacy environment predict children's reading and language skills once maternal language abilities are taken into account. Data come from a longitudinal study…

This empirical study intends to present core results of the change in environmental literacy of German students by analysing PISA 2006 and 2015 data. The study is carried out within the scope of environmental literacy in science education. The data are based on findings of both PISA 2006 data (N= 4891) and PISA 2015 data (N= 6504) of German…

Background: Self-injurious and aggressive behaviours are reported as components of some behavioural phenotypes but there are few studies comparing across syndrome groups. In this study we examined the prevalence of these behaviours and the associated person characteristics in seven genetic syndromes. Methods: Questionnaire data on self-injury and…
