Amaryllidaceae alkaloids exhibit a wide range of physiological effects, of which the acetylcholinesterase (AChE) inhibitory activity is the most relevant. However, scientific evidence related to their neuroprotective effectiveness against glutamate-induced toxicity has been lacking. Thus, the purpose of this study

We measured urinary phthalate metabolites, including di-n-butyl phthalate (DnBP), di-isobutyl phthalate, benzyl butyl phthalate (BBzP), and di(2-ethylhexyl) phthalate (DEHP), from 178 school-aged children and their 284 family members using gas chromatography-mass spectrometry, and we calculated daily phthalate intakes. The highest

During evolution, plants have acquired and/or lost diverse sugar residues as cell-wall constituents. Of particular interest are primordial cell-wall features that existed, and in some cases abruptly changed, during the momentous step whereby land-plants arose from charophytic algal ancestors.
