Immunobiological properties of selected natural and chemically modified phenylpropanoids

Immunobiological properties of selected natural and chemically modified phenylpropanoids

Effects of natural and structurally transformed lignans compared with stilbenes or stilbenoids on production of nitric oxide (NO) triggered by lipopolysaccharide (LPS) and interferon-γ (IFN-γ), tested under in vitro conditions using murine resident peritoneal macrophages, are reviewed. Relation between the molecular structure and immunobiological activity was investigated, and implication of su...

Properties of Chemically Modified Gelatin Films

Edible and/or biodegradable films usually have limited water vapor barriers, making it difficult to use them. Thus, the objective of this work was to evaluate the effect of a chemical reticulation treatment with formaldehyde and glyoxal on the mechanical properties, water vapor permeability, solubility and color parameters of gelatin-based films. Formaldehyde and glyoxal were added to the filmo...

Friction properties of chemically modified starch

Starches of varying chemical structures were esterifi ed with anhydrides, formulated into dry fi lm lubricants with the addition of canola oil, and its friction properties investigated. In the absence of canola, chemically modifi ed starch displayed a very high coeffi cient of friction (COF). Addition of canola resulted in a sharp decrease in COF, which decreased with increasing [canola] until ...
