Nanoemulsion and emulsion vitamin D fortified edible film based on quince seed gum.

In this research, emulsions and nanoemulsions containing two concentrations of vitamin D were added to quince seed gum film and its properties were examined. Incorporation of emulsified oil droplets to the films structure was confirmed by FTIR. It was observed that presence of emulsion and nanoemulsion in the films, increased their thickness, opacity, and hydrophobicity and interaction of the gum chains with water molecules was decreased and so, water vapor permeability, water solubility, and moisture content decreased.

Anti-thyroid peroxidase antibody and vitiligo: a controlled study.

Background: Vitiligo is an acquired depigmenting disorder due to destruction of melanocytes. Although many theories have been suggested for its pathogenesis, the role of autoimmunity is the most popular one. The association of vitiligo with autoimmune thyroid diseases and the increased prevalence of autoantibodies including thyroid autoantibodies in vitiligo favor this role.
