the compounds a combined neuroprotective and neuritogenic activity in the nanomolar range. The potent antioxidant activity of these natural products seems to be involved in part of their mechanism of action. This study provides the first description of natural neurotrophin mimetics present in Annonaceae extracts, and led to the biological characterization of compounds, which present a potential interest
Provided is a polymer that is capable of affording a heat storage material superior in humidity permeability and shape retention after phase transition and that is superior in molding processability, namely, a polymer including constitutional units (A) derived from ethylene, constitutional units (B) represented by a specified formula, and optionally including constitutional units (C) represented by a specified formula, wherein where the total number of the units (A), the units (B), and the units (C) is 100%, the number of the units (A) accounts for 70% to 99%, the total number of the units (B) and the units (C) accounts for 1% by weight to 30% by weight, and where the total number of the units (B) and the units (C) is 100%, the number of the units (B) accounts for 1% to 100% and the number of the units (C) accounts for 0% to 99%.
