Aims: This study explores the total quantity of sulfur secondary metabolites in the plant organs of garlic and ramsons, the content of total phenol and their correlation to the antioxidant capacity (AOC). There are different reports about correlation of secondary

Contact lenses suffer from two limitations: low oxygen permeability and deposition of protein and lipids. In order to prevent bioadhesion, surface must be completely inert to all biological reactions. To achieve this, surface properties must be tailored. Also, to improve comfort, surface must be highly wettable and lubricous. In this paper the surface of silicone contact lenses was modified by plasma induced copolymerization of acrylic acid. A wettable surface was generated and in addition carboxyl groups that were created on the surface provided an ideal reactive platform for subsequent grafting of polyethylene glycol. Each surface modification step was analysed by XPS and contact angle measurements. Lysozyme adsorption on modified silicone contact lenses was analysed by surface-MALDI-ToF-MS and XPS. After incubation with lysozyme, surface-MALDI-TOF-MS and XPS analysis showed a reduction of adsorbed lysozyme on hydrogel modified contact lenses. Surface modification of silicone with PEG is a method for reduction of protein adsorption on contact lenses.

This paper analyzes how oral production is developed in an English textbook for the 6th grade approved by the “PNLD”, from the perspectives of genre (socio-discursive and sociorhetorical approaches) and new literacy studies, evaluating its adequacy for the efficient use of oral genres.
