Effects of developmental arsenite exposure on hippocampal synapses in mouse offspring.

Arsenic exposure through drinking water can impair the learning and memory ability of children in China and other countries. Synaptic plasticity plays a key role in the process of learning and memory. Alterations in the expression of presynaptic and postsynaptic proteins can be used to evaluate synaptic plasticity, and further to evaluate impairment in learning and memory ability.

[Progress on classification and identification of Acanthamoeba].

As a pathogenic free-living amoeba, Acanthamoeba is easy to be recognized at the genus level, but difficult to identify at species level on the morphological basis. This review summarizes the methods for Acanthamoeba species classification and identification.
