One hospice's project to honor and care for veterans.

This article explains Hospice of Dayton's program to care for veterans at end-of-life using 2 case studies as examples. Instructions, opportunities, and the unique challenges for support and care of this population at end-of-life are illustrated.

Self-aggregation of a polyalanine octamer promoted by its C-terminal tyrosine and probed by a strongly enhanced vibrational circular dichroism signal.

The eight-residue alanine oligopeptide Ac-A(4)KA(2)Y-NH(2) (AKY8) was found to form amyloid-like fibrils upon incubation at room temperature in acidified aqueous solution at peptide concentrations >10 mM. The fibril solution exhibits an enhanced vibrational circular dichroism (VCD) couplet in the amide I' band region that is nearly 2 orders of magnitude larger than typical polypeptide/protein signals in this region. The UV-CD spectrum of the fibril solution shows CD in the region associated with the tyrosine side chain absorption.
