Plant K+ Transport: Not Just an Uphill Struggle
Most plant cells can accumulate K+ to concentrations much higher than those in the external medium. Recent studies are providing new insights into the relative roles of channels and transporters in K+ accumulation. These studies are also pointing to specific roles for K+ channels and transporters in polarized development.

متن کاملAn uphill struggle: effects of a point-of-choice stair climbing intervention in a non-English speaking population.
BACKGROUND Increases in lifestyle physical activity are a current public health target. Interventions that encourage pedestrians to choose the stairs rather than the escalator are uniformly successful in English speaking populations. Here we report the first test of a similar intervention in a non-English speaking sample, namely the Hong Kong Chinese. METHODS Travellers on the Mid-Levels esca...
متن کاملUphill/downhill nystagmus
Differential diagnosis between peripheral and central spontaneous nystagmus can be difficult to classify (as peripheral or central) even on the basis of criteria recommended in the recent literature. The aim of this paper is to use the combination of spontaneous nystagmus and ocular tilt reaction to determine the site of origin of the disease that causes nystagmus. We propose to classify the ny...
متن کاملMegafauna moves nutrients uphill
Large animals have a disproportionate capacity to transport nutrients along gradients and against water flow directions, making them more available to ecosystems and ultimately saving them from disappearing in sea floor sediments. Megafauna extinctions have reduced this capacity dramatically, while humans and their livestock aren’t stepping in to restore this important ecosystem service.
