S-Nitrosylation of DRP1 does not affect enzymatic activity and is not specific to Alzheimer's disease.
Mitochondrial dysfunction and synaptic loss are among the earliest events linked to Alzheimer's disease (AD) and might play a causative role in disease onset and progression. The underlying… Expand

Analyses and localization of pectin-like carbohydrates in cell wall and mucilage of the green alga Netrium digitus
The unicellular, simply shaped desmid Netrium digitus inhabiting acid bog ponds grows in two phases. Prior to division, the cell elongates at its central zone, whereas in a second phase, polar tip… Expand
