A time-to-onset analysis for family-based samples was performed on the genomewide association (GWAS) data for attention deficit hyperactivity disorder (ADHD) to determine if associations exist with...

Genome-wide association scan of attention deficit hyperactivity disorder (In special issue: Special Issue on the Genetics of ADHD Dedicated to the Memory of Richard Todd) (2008)

Neale, Benjamin M., Lasky-Su, Jessica, Anney, Richard, Franke, Barbara, Zhou, Kaixin, Maller, Julian B., ...

Results of behavioral genetic and molecular genetic studies have converged to suggest that genes substantially contribute to the development of attention deficit/hyperactivity disorder (ADHD), a...

Gene-social environment interplay in relation to attention deficit hyperactivity disorder (2008)

Daley, Dave, Sonuga-Barke, Edmund, Thompson, Margaret, Chen, Wai

Recent studies of gene–environment interplay in psychiatric disorders have highlighted the complex relationship between genetic and environmental influences. Most published studies on attention...

Genome-wide association scan of the time to onset of attention deficit hyperactivity disorder. (2008)

Lasky-Su, Jessica, Anney, Richard J.L., Neale, Benjamin M., Franke, Barbara, Zhou, Kaixin, Maller, Julian B., ...

Does parental expressed emotion moderate genetic effects in ADHD? An exploration using a genome wide association scan (2008)

Lasky-Su, Jessica, Neale, Benjamin M., Oades, Robert, Chen, Wai, Franke, Barbara, ...

Studies of gene × environment (G × E) interaction in ADHD have previously focused on known risk genes for ADHD and environmentally mediated biological risk. Here we use G × E analysis in the...

The dopamine receptor D4 7-repeat allele and prenatal smoking in ADHD-affected children and their unaffected siblings: no gene–environment interaction (2008)

Altink, Marieke E., Arias-Vásquez, Alejandro, Franke, Barbara, Buschgens, Cathelijne J.M., Rommelse, Nanda N.J., ...

Background: The dopamine receptor D4 (DRD4) 7-repeat allele and maternal smoking during pregnancy are both considered as risk factors in the aetiology of attention deficit hyperactivity disorder...

Association of ADHD with genetic variants in the 5'-region of the dopamine transporter gene: evidence for allelic heterogeneity (2008)

Brookes, K.J., Xu, X., Anney, R., Franke, B., Zhou, K., Chen, Wai, ...

Multiple studies have reported an association between attention deficit hyperactivity disorder (ADHD) and the 10-repeat allele of a variable number tandem repeat (VNTR) polymorphism in the...

Autism symptoms in attention-deficit/hyperactivity disorder: a familial trait which correlates with conduct, oppositional defiant, language and motor disorders (2008)

Mulligan, Aisling, Anney, Richard J.L., O'Regan, Myra, Chen, Wai, Butler, Louise, Fitzgerald, Michael, ...

It is hypothesised that autism symptoms are present in Attention-Deficit/Hyperactivity Disorder (ADHD), are familial and index subtypes of ADHD. Autism symptoms were compared in 821 ADHD probands,...

Brookes, Keeley-Joanne, Buitelaar, Jan, Anney, Richard, Bitsakou, Paraskevi, Baeyens, Dieter, ...

A major goal of genetic studies of attention deficit hyperactivity disorder (ADHD) is to identify individual characteristics that might help segregate the disorder's inherent heterogeneity. [Mill et...

Confirmation that a specific haplotype of the dopamine transporter gene is associated with combined-type ADHD (2007)

Asherson, Phillip, Brookes, Keeley, Franke, Barbara, Chen, Wai, Gill, Michael, Ebstein, Richard P., ...

Objective: The primary purpose of this study was to confirm the association of a specific haplotype of the dopamine transporter gene and attention deficit hyperactivity disorder (ADHD), which could...

The IMAGE project: methodological issues for the molecular genetic analysis of ADHD (2006)

Kuntsi, Jonna, Neale, Benjamin M, Chen, Wai, Faraone, Stephen V, Asherson, Philip

Abstract The genetic mechanisms involved in attention deficit hyperactivity disorder (ADHD) are being studied with considerable success by several centres worldwide. These studies confirm prior...

Mobility Approaches for All IP Wireless Networks (2001)

Onur Altintas, Ashutosh Dutta, Wai Chen, Henning Schulzrinne

Several protocols and mechanisms have been developed to support inter-domain mobility and intra-domain mobility for multimedia services in the Internet. However choosing the right kind of mobility...

Dynamic Resource Assignment Strategies for PCS Data Services (1999)

Jeu-yih Jeng, Yi-bing Lin, Wai Chen

For high speed mobile communication applications, the data rate can be increased by using multiple channels (or time slots) instead of single channel (or time slot). To reduce the high blocking rate...

Impact of Busy Lines and Mobility on Call Blocking in a PCS Network (1996)

Wai Chen, Yi-bing Lin

Several analytical models have been proposed to study the blocking probability for personal communication services networks or mobile phone networks. These models cannot accurately predict the...
