Autism, which is common in individuals with fragile X syndrome, is often difficult to diagnose. We compared the diagnostic classifications of two measures for autism diagnosis, the ADOS and the ADI-R, in addition to the DSM-IV-TR in 63 males with this syndrome. Overall, 30% of the subjects met criteria for autistic disorder and 30% met criteria…

Discovery of RNA-mediated interference (RNAi) is widely recognized as one of the most significant molecular biology breakthroughs in the past 10 years. There is a need for science educators to develop teaching tools and laboratory activities that demonstrate the power of this new technology and help students to better understand the RNAi process.…

Background: Little is known about behavioural flexibility in children and adults with Angelman syndrome and whether people with this syndrome have more or less problems in being behaviourally flexible as compared with other people. Method: Behavioural flexibility scores were assessed in 129 individuals with Angelman syndrome using 11 items from…

In order to study the broader phenotype of infantile autism (IA) we compared the rates and types of epilepsy and other neurological diseases in the parents of 111 consecutively admitted patients with IA with a matched control group of parents of 330 children from the general population. All participants were screened through the nationwide Danish…

As part of a longitudinal twin study of literacy and language, we conducted a behaviour-genetic analysis of orthographic learning, spelling and decoding in Grade 2 children (225 identical and 214 fraternal twin pairs) in the United States and Australia. Each variable showed significant genetic and unique environment influences. Multivariate…

To supplement the summer reading of National Science Teachers Association (NSTA) members, the NSTA Committee on Research in Science Education suggested a list of science education research articles that were published in the journals of NSTA's affiliates in 2012. These articles covered a variety of topics that include learning about…

The described interdisciplinary course helped a mixed population of in-service secondary English and biology teacher-participants increase their genetics content knowledge and awareness of Ethical, Legal, and Social Implications (ELSI) that arose from discoveries and practices associated with the Human Genome Project. This was accomplished by…

A considerable amount of research has examined factors associated with the etiology and maintenance of anxiety disorders in children. The familial nature of anxiety has been well-established, with genetic studies showing that approximately 30% of the variance is accounted for by genetic factors. Research into the family environment documents…

Background: Traumatic brain injury (TBI) in infancy is relatively common, and is likely to lead to poorer outcomes than injuries sustained later in childhood. While the headlines have been grabbed by infant TBI caused by abuse, often known as shaken baby syndrome, the evidence base for how to support children following TBI in infancy is thin.…

This case study describes an information literacy lab for an undergraduate biology course that leads students through a range of resources to discover aspects of genetic information. The lab provides over 560 students per semester with the opportunity for hands-on exploration of resources in steps that simulate the pathways of higher-level…

The association between educational attainment and self-assessed health is well established but the mechanisms that explain this association are not fully understood yet. It is likely that part of the association is spurious because (genetic and non-genetic) characteristics of a person's family of origin simultaneously affect one's educational…

The Tampa Bay Community Cancer Network (TBCCN) is one of 25 Community Network Programs funded by the National Cancer Institute's (NCI's) Center to Reduce Cancer Health Disparities with the objectives to create a collaborative infrastructure of academic and community based organizations and to develop effective and sustainable interventions to…

The nervous system contains some of the body's most metabolically demanding cells that are highly dependent on ATP produced via mitochondrial oxidative phosphorylation. Thus, the neurological system is consistently involved in patients with mitochondrial disease. Symptoms differ depending on the part of the nervous system affected. Although almost…

In addition to hypotonia and relative sarcopenia, patients with Prader-Willi syndrome (PWS) show reduced spontaneous physical activity and gait disorders. Scant evidence exists that daily muscle training increases their lean mass and physical activity levels. Whether adequate long-term physical training is feasible and effective in improving…

Objective: To explore pretreatment and short-term improvement variables as potential moderators and predictors of 12-month follow-up outcome of unsupported online computerized cognitive behavioral therapy (CCBT), usual care, and CCBT combined with usual care for depression. Method: Three hundred and three depressed patients were randomly allocated…
