Templates that induce alpha-helical, beta-sheet, and loop conformations
Article Abstract:
The nucleation and extension of a conformation from an arranged template region by a disordered alpha-amino acid-based region achieved by using templates, lead to alpha-helices and beta-sheet structures. The porphyrin, pyridine- and bipyridine-based templates cause alpha-helical folding. Small cyclic and acyclic templates are utilized for obtaining the folded state. Beta-turn mimics are responsible for the folding of the peptide fragments into beta-sheet structure. A beta-turn template substitutes the i+1 and i+2 residues of a beta-turn.

Extended stimulated parotid and submandibular secretion in a healthy young and old population
Article Abstract:
Morphological studies of unmedicated individuals indicate the retention of secretory capacity by parotid glands of persons of various ages even under conditions of intense stimulation. However, gustatory stimulus induces variations in fluid secretion by the submandibular gland, depending on the age of the individual. Younger individuals exhibit an increase in salivary flow rate with stimulation.

Lines in the dirt: pornography
Article Abstract:
Some US feminists, lead by Catherine MacKinnon, have proposed laws to redefine pornography as obscene if it depicts the subordination of women. Canada now accepts such a definition, but in the US the American Civil Liberties Union and others oppose it.
