• Many plants combine sexual reproduction with vegetative propagation, but how trade-offs between these reproductive modes affect fitness is poorly understood. Although such trade-offs have been demonstrated at the level of individual shoots (ramets), there is little evidence that they scale up to affect genet fitness. For hermaphrodites, reproductive investment ...

The silver ion (Ag+) is well documented to be a potent inhibitor of sodium (Na+) transport in fish. However, it has not been determined whether silver nanoparticles (Ag NPs) elicit this same effect and if so, if the NP itself and/or the dissociation of ionic Ag+ causes this effect. Citrate-capped ...

Advanced glycation end products (AGEs) accumulate in aging and several pathologies such as Alzheimer disease and diabetes. These protein products are known to inhibit proteolytic pathways. Moreover, AGEs are known to be involved in the activation of immune responses. Here we demonstrate that AGEs induce the expression of immunoproteasomal subunits. ...
