International environmental cooperation: a new eye on the greenhouse gas emissions' control

Cyclic Guanosine Monophosphate

Since we have previously shown a direct inhibitory effect of platelet-activating factor (PAF) on Cl reabsorption in the medullary thick ascending limb of Henle's loop (TAL), the aim of this study was to extend this effect to the whole TAL and to further investigate the signaling pathway involved. In microperfused cortical TALs, PAF significantly decreased Cl reabsorption by 50.3±6.5%. On the on...

Object-based attention: strategy versus automaticity.

This article begins with a description of space- and object-based guidance of attentional selection. It goes on to discuss the most influential, two-rectangle, paradigm for demonstrating the existence of space- and object-based attentional effects. The article then considers two different mechanisms, attentional spreading and attentional prioritization, that can potentially explain how object r...
