Harden, K. Paige; Mendle, Jane; Hill, Jennifer E.; Turkheimer, Eric; Emery, Robert E. – Journal of Youth and Adolescence, 2008
The relation between timing of first sex and later delinquency was examined using a genetically informed sample of 534 same-sex twin pairs from the National Longitudinal Study of Adolescent Health, who were assessed at three time points over a 7-year interval. Genetic and environmental differences between families were found to account for the…

Moss, Joanna F.; Oliver, Chris; Berg, Katy; Kaur, Gurmeash; Jephcott, Lesley; Cornish, Kim – American Journal on Mental Retardation, 2008
Autism spectrum disorder characteristics have not been evaluated in Cornelia de Lange and Cri du Chat syndromes using robust assessments. The Autism Diagnostic Observation Schedule and Social Communication Questionnaire were administered to 34 participants with Cornelia de Lange syndrome and a comparison group of 23 participants with Cri du Chat…

Merritt, Robert B.; Bierwert, Lou Ann; Slatko, Barton; Weiner, Michael P.; Ingram, Jessica; Sciarra, Kristianna; Weiner, Evan – American Biology Teacher, 2008
First reported in the early 1930s, variation in the ability to taste phenylthiocarbamide (PTC) has since become one of the most widely studied of all human genetic traits. Guo and Reed (2001) provide an excellent review of work on this polymorphism prior to the identification and sequencing of the PTC gene by Kim et al. (2003), and Wooding (2006)…

Patterson, David – Down Syndrome Research and Practice, 2008
Folate is an important vitamin that contributes to cell division and growth and is therefore of particular importance during infancy and pregnancy. Folate deficiency has been associated with slowed growth, anaemia, weight loss, digestive disorders and some behavioural issues. Adequate folate intake around the time of conception and early pregnancy…

Herrero, Salvador; Ivorra, Jose Luis; Garcia-Sogo, Magdalena; Martinez-Cortina, Carmen – Biochemistry and Molecular Biology Education, 2008
Using the traditional serological tests and the most novel techniques for DNA fingerprinting, forensic scientists scan different traits that vary from person to person and use the data to include or exclude suspects based on matching with the evidence obtained in a criminal case. Although the forensic application of these methods is well known,…

Asraoui, Jimmy F.; Sayar, Nancy P.; Knio, Khouzama M.; Smith, Colin A. – Biochemistry and Molecular Biology Education, 2008
In this article, we describe an inexpensive, two-session undergraduate laboratory activity that introduces important molecular biology methods in the context of biodiversity. In the first session, students bring tentatively identified flies (order Diptera, true flies) to the laboratory, extract DNA, and amplify a region of the mitochondrial gene…

Stansfield, William D. – American Biology Teacher, 2008
Gregor Mendel (1822-1884) is rightly credited as being the "father of modern genetics." He presented the results of his pea experiments at a meeting of his local natural history society in two lectures during 1865. His paper was published in the proceedings of the society the next year. From his breeding experiments with the edible pea, he…

Blazer, Dan G. – Gerontologist, 2008
Research has shown over the years that the self-perceptions of older adults about their health and well-being may be at least as important as objective data for predicting the course of their health over time. I review a series of studies that span 30 years in which I and my colleagues have asked older adults in the community about their…

Peekhaus, Wilhelm – Government Information Quarterly, 2008
This paper explores whether the Canadian legislative protections in place to safeguard medical privacy meet the expectations of Canadians. An overview of current governance systems designed to protect the privacy of personal health information at both the federal and provincial levels is first presented. This is followed by an empirical analysis…

Antion, Marcia D.; Merhav, Maayan; Hoeffer, Charles A.; Reis, Gerald; Kozma, Sara C.; Thomas, George; Schuman Erin M.; Rosenblum, Kobi; Klann, Eric – Learning & Memory, 2008
Protein synthesis is required for the expression of enduring memories and long-lasting synaptic plasticity. During cellular proliferation and growth, S6 kinases (S6Ks) are activated and coordinate the synthesis of de novo proteins. We hypothesized that protein synthesis mediated by S6Ks is critical for the manifestation of learning, memory, and…

Yoon, Susan – Journal of Research in Science Teaching, 2008
This study investigated seventh grade learners' decision making about genetic engineering concepts and applications. A social network analyses supported by technology tracked changes in student understanding with a focus on social and conceptual influences. Results indicated that several social and conceptual mechanisms potentially affected how…

Hwang, Gwo-Jen; Yin, Peng-Yeng; Hwang, Chi-Wei; Tsai, Chin-Chung – Educational Technology & Society, 2008
Cooperative learning is known to be an effective educational strategy in enhancing the learning performance of students. The goal of a cooperative learning group is to maximize all members' learning efficacy. This is accomplished via promoting each other's success, through assisting, sharing, mentoring, explaining, and encouragement. To achieve…

T. J. M.; Wokke, John H. J.; Nelis, Eva; De Jonghe, Peter; Timmerman, Vincent – Brain, 2008
Distal hereditary motor neuropathy (HMN) is a clinically and genetically heterogeneous group of disorders affecting spinal alpha-motor neurons. Since 2001, mutations in six different genes have been identified for autosomal dominant distal HMN; "glycyl-tRNA synthetase (GARS)," "dynactin 1 (DCTN1)," "small heat shock 27 kDa…

Ewers, Michael; Zhong, Zhenyu; Burger, Katharina; Wallin, Anders; Blennow, Kaj; Teipel, Stefan J.; Shen, Yong; Hampel, Harald – Brain, 2008
The Apolipoprotein (ApoE) [epsilon]4 allele is a major genetic risk factor of Alzheimer's disease, and may affect the production of amyloid beta (A[beta][subscript 1-42]). Recently, we have shown that [beta]-secretase (BACE 1) activity can be reliably detected within the brain and human CSF. Here, we have examined an association between the ApoE…

Kortsarts, Yana; Morris, Robert W.; Utell, Janine M. – Information Systems Education Journal, 2010
Bioinformatics is a relatively new interdisciplinary field that integrates computer science, mathematics, biology, and information technology to manage, analyze, and understand biological, biochemical and biophysical information. We present our experience in teaching an interdisciplinary course, Introduction to Bioinformatics, which was developed…
