In the wake of increasing population and rising average per caput consumption of food fi sh and a plateauing off of the traditional food fi sh supplies there is an urgent need to close the increasing gap between supply and demand. It is generally acknowledged that aquaculture would increasingly contribute to closing this gap. Aquaculture production is still and likely to continue to be dominate...

Tyrosine (TYR), an amino acid found in various foods, has been shown to increase dopamine (DA) levels in the brain. Recent studies have provided evidence that TYR supplementation can improve facets of cognitive control in situations with high cognitive demands. Here we investigated whether TYR promotes cognitive flexibility, a cognitive-control function that is assumed to be modulated by DA. We...

BACKGROUND AND OBJECTIVES Research suggests mindfulness-based treatments may enhance efficacy of CBT for Generalized Anxiety Disorder (GAD). One hypothesized mechanism of mindfulness is cognitive flexibility; however, research findings to date are mixed as to a) whether cognitive inflexibility represents a characteristic of GAD, and b) whether mindfulness impacts cognitive flexibility. It is pr...

Differentiation of T helper (Th) subset 2 effector lymphocytes is thought to foreclose on IFN-gamma gene expression. Using an IL-4 locus modified to detect transcriptional induction of this effector cytokine gene in developing Th2 cells, we show here that these cells contributed effectively to a long-term memory population. A memory CD4 subset formed efficiently from an activated population aft...

We prove that the action of the special automorphism group on affine cones over del Pezzo surfaces of degree 4 and 5 is infinitely transitive.

We thank Dr Paul D. Williams, Dr Mama A. Mamas, and Dr Douglas G. Fraser for their interest in our article. First, we investigated the stent fracture after Xience V (Abbott Vascular) and Promus (Boston Scientific). As they note, our results, therefore, do not apply to all everolimus-eluting stents. Second, they suggest that double stent strut layer shown in Figure 4 is the consequence of stent ...
