Evidence from both human and animal studies implicates the serotonergic system in the development of attention-deficit hyperactivity disorder (ADHD) including positive association studies for several key serotonergic genes. The serotonin transporter (HTT) regulates the availability of serotonin by reuptake of the neurotransmitter from the synaptic cleft. Several studies have reported an association of this gene to ADHD, specifically the long variant of a common insertion/deletion polymorphism located in the promoter of this gene that results in increased transcription and higher HTT expression. An additional study found no evidence for an association with this polymorphism. Recently, an A/G single nucleotide polymorphism (SNP) was found within the promoter polymorphism with functional studies indicating that the long variant containing the G allele at this site behaves like the short variant. This previously unidentified functional change may have confounded earlier association studies. We investigated the relationship of several variants to ADHD: the promoter polymorphisms, SNP in the 3' untranslated region (3'UTR) with a reported association to ADHD and a rare, non-synonymous coding SNP. These polymorphisms were genotyped in 209 ADHD families identified through an affected proband. We did not find evidence for an association of these polymorphisms, or haplotypes of these polymorphisms, to ADHD in this sample.

Using the British Sikh community as its research context, this article explores the influence of the Bollywood film genre on what Vertovic refers to as the ''diasporic consciousness'' in relation to this community. Bollywood attempts to speak to the diaspora by conveying a new sense of ''Indian-ness,'' one that is less about citizenship and more about imagined identity and community. The authors investigate what they have termed the ''Indian imaginary'' and how the values embedded therein impact on the lives of young British Sikhs. The findings discuss three emergent core themes: (1) reaffirming pride in Indian heritage; (2) evoking romance and longing; and (3) reinforcing family values and a sense of kinship within the British Sikh diaspora. The overall contribution of the article is twofold. First, it illustrates how the globalization of Bollywood affects the Indian diaspora at a local level. Second, it shows how Bollywood provides an important space for negotiating and reconciling various tensions between family-based and more individualistic value systems. Ultimately, then, Bollywood offers young British Sikhs a particular, hybridized representation of courtship and marriage that is both romantic and familial, and that serves to reconcile Eastern and Western marital relationship ideals and oppositional cultural discourses.
