A model of zinc dynamics evoked by intense stimulation at the cleft of hippocampal mossy fiber synapses.

Zinc is a transition metal that is particularly abundant in the mossy fibers of the hippocampal CA3 area. Despite the large number of studies about the zinc role in mossy fibers, the action of zinc in synaptic mechanisms is only partly known. The use of computational models can be a useful tool for this study.

A study of bio-hybrid silsesquioxane/yeast: Biosorption and neuronal toxicity of lead.

Lead is a heavy metal of high impact for the environment as well as for human health, being cause of several diseases. Considering the importance of obtaining an effective treatment for lead removal, a new hybrid material was developed for sorption of Pb from aqueous solution. The effect of pH, temperature, liquid/solid ratio (g/cm) and lead concentration on the sorption capacity of yeasts chemically modified with cubic silsesquioxane (YS) was analyzed.
