“Catechol-O-methyltransferase (COMT) modulates dopamine in the prefrontal cortex (PFC) and influences PFC dopamine-dependent cognitive task performance. A human COMT polymorphism (Val(158)Met) alters enzyme activity and is associated with both the activation and functional connectivity of the PFC during task performance, particularly working memory. Here, we used functional magnetic resonance imaging and a data-driven,

GSK1838705A in vitro independent components analysis (ICA) approach to compare resting state functional connectivity within the executive control network (ECN) between young, male COMT Val(158) (n=27) and Met(158) (n=28) homozygotes. COMT genotype effects on grey matter were assessed using voxel-based morphometry. COMT genotype significantly modulated functional connectivity within the ECN, which included the head of the caudate, and anterior cingulate and frontal cortical regions. Val(158) homozygotes showed greater functional connectivity

between a cluster within the left ventrolateral PFC and the rest of the ECN (using a threshold of Z>2.3 and a family-wise error cluster significance level of p<0.05). This difference occurred in the absence of any alterations in grey matter. Our data show that COMT Val(158)Met affects the functional connectivity of the PFC at rest, complementing its prominent role in the activation and functional connectivity of this region during cognitive task performance. The results suggest that genotype-related differences in prefrontal GSK2245840 nmr dopaminergic tone result

in neuroadaptive changes in basal functional connectivity, potentially including subtle COMT genotype-dependent differences in the relative coupling of task-positive and task-negative regions, which could in turn contribute to its effects on brain activation, connectivity, and behaviour.

“The last decade has witnessed a revolution in small bowel (SB) endoscopy technologies. Endoscopists are no longer confined to the use of push enteroscopy or the significantly more invasive intraoperative enteroscopy: SB capsule endoscopy (SBCE) and device assisted enteroscopy (DAE) have rapidly enabled endoscopic visualisation of the entire SB without the need for surgery. DAE goes a step further by allowing tissue sampling and the application of endotherapy. These developments have also been parallelled by rapid advances in dedicated radiological SB imaging technologies.
