Self-control is defined as individuals' capacity to alter, modify, change, or override impulses, desires, and habitual responses (Baumeister, 2002; Muraven et al., 2005). Capacity for self-control is important and adaptive. Without it, we would be " slaves " to habits and impulses and unable to engage in sustained, goal-directed behavior. Loss of self-control has been shown to be related to num...

Habitat can influence disease directly, through effects on hosts and parasites, or indirectly, through effects on ecological drivers of disease. We illustrated direct and indirect connections between habitat and outbreaks using a case study in the plankton. We sampled yeast epidemics in 18 populations of the lake zooplankter Daphnia dentifera. Lake size drove variation in two types of habitat s...

Snail1 and Zeb1 are E-cadherin-transcriptional repressors induced during epithelialmesenchymal-transition (EMT). In this article we have analyzed the factors controlling Zeb1 expression during EMT. In NMuMG cells treated with TGF-β, Snail1 RNA and protein are induced one hour after addition of the cytokine preceeding Zeb1 up-regulation that requires six to eight hours. Zeb1 gene expression is c...

We investigated the renal response to direct renal nerve stimulation, 2 weeks following reversal of 24-hr unilateral (left) ureteric obstruction. Renal nerve stimulation caused a 13-15% fall in renal blood flow, in 4 groups of anaesthetised rats following ureteric obstruction (n=9) or a sham operation (n=7) both with (n=9) and without (n=7) treatment with the mixed ETA/B receptor antagonist, bo...

We thank Schimek for his thoughtful letter. We agree that the American Association of State Highway and Transportation Officials (AASHTO) encourages bike paths; however, AASHTO’s definition of a bike path is a shared use path for pedestrians, skaters, wheelchair users, joggers, and other nonmotorized users. AASHTO discourages bicycle-only cycle tracks because, as noted by Schimek, AASHTO discou...

This research compares the role of initial individual characteristics to that of patterns of resolution in which successive dominance relationships are established during the formation of triads in the domestic hen. Combining weight, prior victory or defeat in the site of encounter, and comb size, we created three levels of asymmetries on characteristics for triads of hens. The effects of these...
