Exposing S. pistillata to seawater with an elevated calcium concentration resulted in up - regulation of gene expression during the day relative to the night.

Not exact matches

When elevating calcium ion concentration directly at the presynaptic terminal with the use of caged calcium, cleavage of SNAP - 25 by botulinum toxin A (BoNT / A) produced a strong reduction in the calcium sensitivity for release, whereas cleavage of syntaxin using BoNT / C1 and synaptobrevin using tetanus toxin (TeNT) produced an all - or - nothing block without changing the kinetics of remaining vesicles.

Further experiments revealed that injured cells initiate a wave of elevated calcium ion concentration that travels through the brain, and that the microglia only begin migrating when the wave reaches them.

Tropical Porites corals adjust their internal pH in order to enable themselves to form calcium carbonate and grow under elevated carbon dioxide concentrations — even for a longer period of time.

Elevated atmospheric CO2 is associated with decreased plant nitrogen concentration, and therefore decreased protein, in many crops, such as barley, sorghum, and soy.210, 211,212,213 The nutrient content of crops is also projected to decline if soil nitrogen levels are suboptimal, with reduced levels of nutrients such as calcium, iron, zinc, vitamins, and sugars, although this effect is alleviated if sufficient nitrogen is supplied.214 Fourth, farmers are expected to need to use more herbicides and pesticides because of increased growth of pests215, 216,217,218 and weeds219, 220 as well as decreased effectiveness221 and duration222of some of these chemicals (Ch.
