       The photodegradation  and degradation of two azo group containing dyes namely; methyl orange (MO) as mono azo model and congo red (CR) as di azo model moieties, have been investigated, throughout this thesis, in aqueous medium. Three different nitrogen content (2.5%, 5% and 7%) laboratory synthesized doped anatase TiO₂ nano particles (N-TiO₂) have been employed as a photocatayst utilizing visible light illumination.   The N-TiO₂ photocatalysts have been characterized employing several spectroscopic and electronic tools encompassing.

Hypertension (HT) and cardiovascular diseases (CVD) share in that one of the main reasons for them is to increase the oxidative stress, which in turn increases the severity of the disease and exacerbation of symptoms. Reactive molecules produced from oxidative stress, in addition to causing tissue damage by oxidation of biomolecules like DNA, lipids, proteins and sugars; it is lead to the formation of mediators with potent inflammatory effect.
