Sattler, Barbara – Zero to Three, 2005
Each of the elements required to create a healthy baby--genetics, the anatomy of the male and female reproductive system, the processes by which eggs and sperm are produced, the processes by which the embryo is created and implanted, maternal health during pregnancy, and embryonic/fetal growth and development--is vulnerable to damage by…

Patton, Sharyle – Zero to Three, 2005
Biomonitoring is a public health tool that has been used by scientists and researchers for decades to test blood, bone, urine, hair, human milk, adipose tissue, and other body substances for the presence of toxic chemicals, in order to assess what is called the "chemical body burden." Biomonitoring helps to: (1) identify which chemicals…

Kuravsky, Lev S.; Malykh, Sergey B. – Australian Journal of Educational & Developmental Psychology, 2004
A technique to study combined influence of environmental and genetic factors on the base of changes in phenotype distributions is presented. Histograms are exploited as base analyzed characteristics. A continuous time, discrete state Markov process with piece-wise constant interstate transition rates is associated with evolution of each histogram.…

Muris, Peter – International Journal of Behavioral Development, 2006
Anxiety disorders are among the most prevalent psychiatric problems in children and adolescents. The present article summarizes the main evidence that has accumulated on the pathogenesis of childhood anxiety disorders during the past two decades. Various risk and vulnerability factors (e.g., genetics, behavioral inhibition, disgust sensitivity,…

Kuldell, Natalie – Journal of College Science Teaching, 2003
During three series of molecular genetics experiments, our students engage in ungraded discussions of research articles related to their experiments. The research articles are selected less for their relevance to students' laboratory experience than for their focus on experimental design and the clarity of data presentation. By discussing these…

Boyle, John A. – Biochemistry and Molecular Biology Education, 2002
The working drafts of the human genome, announced in February 2001, have clearly provided a breakthrough in biochemistry and molecular biology research. The scientific data also provide an opportunity to vary a typical approach to teaching. Advanced graduate students at our university can elect to take a course in molecular genetics. The human…

Stromswold, Karin – Cognition, 2006
Results of twin studies clearly demonstrate that genetic factors play an important role in the rate of language acquisition and linguistic proficiency attained by normal and impaired children and adults [see Stromswold, K. (2001). The heritability of language: A review and meta-analysis of twin, adoption and linkage studies. "Language," 77,…

McGough, James; McCracken, James; Swanson, James; Riddle, Mark; Kollins, Scott; Greenhill, Laurence; Abikoff, Howard; Davies, Mark; Chuang, Shirley; Wigal, Tim; Wigal, Sharon; Posner, Kelly; Skrobala, Anne; Kastelic, Elizabeth; Ghuman, Jaswinder; Cunningham, Charles; Shigawa, Sharon; Moyzis, Robert; Vitiello, Benedetto – Journal of the American Academy of Child and Adolescent Psychiatry, 2006
Objective: The authors explored genetic moderators of symptom reduction and side effects in methylphenidate-treated preschool-age children diagnosed with attention-deficit/hyperactivity disorder (ADHD). Method: DNA was isolated from 81 subjects in a double-blind, placebo-controlled, crossover methylphenidate titration. Parents and teachers…

Fearon, R. M. Pasco; Van IJzendoorn, Marinus H.; Fonagy, Peter; Bakermans-Kranenburg, Marian J.; Schuengel, Carlo; Bokhorst, Caroline L. – Developmental Psychology, 2006
The current article presents results from a twin study of genetic and environmental components of maternal sensitivity and infant attachment and their association. The sample consisted of 136 twin pairs from 2 sites: Leiden, the Netherlands, and London, UK. Maternal sensitivity was assessed in the home at 9-10 months, and infant attachment…

Bello, Julia; Butler, Charles; Radavich, Rosanne; York, Alan; Oseto, Christian; Orvis, Kathryn; Pittendrigh, Barry R. – Science Education Review, 2007
Although members of the general public have often heard of the terms "genetic engineering" and, more recently, genomics, they typically have little to no knowledge about these topics, and in some cases are confused about basic concepts in these areas. There is currently a need for teaching models to explain concepts behind genomics.…

Atkin, Keith; Lorch, Marjorie Perlman – Clinical Linguistics & Phonetics, 2007
Prader-Willi syndrome (PWS) is a genetic disorder which has widespread developmental consequences including motor, cognitive and language delay. Previous research on PWS children has focused primarily on phonological development and dysfluency. In the present study, the lexical development of a boy with PWS was investigated in a series of 18 play…

Forsman, Mats; Larsson, Henrik; Andershed, Henrik; Lichtenstein, Paul – British Journal of Developmental Psychology, 2007
This study tested if persistent externalizing behaviour and symptoms of Attention Deficit Hyperactivity Disorder (ADHD) in childhood are associated with personality and behavioural aspects of the psychopathic personality constellation in adolescence. The target sample consisted of all 1,480 twin pairs born in Sweden between 1985 and 1986.…

Kaffman, Arie; Meaney, Michael J. – Journal of Child Psychology and Psychiatry, 2007
Parental care plays an important role in the emotional and cognitive development of the offspring. Children who have been exposed to abuse or neglect are more likely to develop numerous psychopathologies, while good parent-infant bonding is associated with improved resiliency to stress. Similar observations have also been reported in non-human…

Rowe, Richard; Simonoff, Emily; Silberg, Judy L. – Journal of Child Psychology and Psychiatry, 2007
Background: Growing evidence indicates a link between unintentional injury and both disruptive and emotional psychopathology. We present further evidence of these associations and address the underlying mechanisms. We also examine the genetic contribution to unintentional injury. Methods: The Virginia Twin Study of Adolescent Behavioral…

Lopez-Perez, Ruben; Lopez-Morales, Patricia; Borges-Yanez, S. Aida; Maupome, Gerardo; Pares-Vidrio, Gustavo – Down Syndrome Research and Practice, 2007
This study sought to determine the prevalence of bruxism in a Mexican community of children with Down syndrome, and to evaluate bruxism's relationship with age, sex, intellectual disability level, and type of chromosomal abnormality of trisomy 21. Using a cross-sectional design, 57 boys and girls (3 to 14 years old) were examined. Three approaches…
