MANGANESE AND THE ROLE IT PLAYS IN THE HUMAN BODY Introduction Manganese is one of sixteen known minerals that are essential within the human diet (wardlaw). Minerals, such as manganese, are considered essential to the diet of humans if their absence results in physiological or structural abnormalities and their presence prevents disease/illness (wardlaw). The body utilizes manganese primarily in energy metabolism and within the antioxidant systems (wardlaw). Manganese is found primarily in parts

In the present study, the rat model of depression was induced by the daily i.p. injection of reserpine for 15 days. This was followed by monitoring the motor activity to check the development of the rat model of depression. Then the depressed rats were treated with cannabis extract to study its effect on this model. After 15 days of daily reserpine injection, a significant decrease in motor activity was recorded as assessed by the open field test (OFT). Together with the hunched back appearance

observed in the present study. This was evidenced by significant elevation in kidney MDA content. These results match the increase in lipid peroxidation post irradiation obtained by Srinivasan et al. (2007) and Pratheeshkumar and kuttan (2011). Free radicals generated by irradiation react with unsaturated lipids generating hydroperoxides, which in turn can induce changes in lipid bilayer thereby altering the membrane permeability and inducing lipid peroxidation (Suzuki et al. 1997). Also, significant

onset of tissue damage through diseases to finally apoptosis (Agrawal and Sharma 2010). Damage induced by oxidative stress occurs through the production of reactive oxygen species (ROS) which includes oxygen derived free radicals such as superoxide anion, hydroxyl radical and non radical derivatives as hydrogen peroxide (Tebourbi et al. 2011; Verma et al. 2007). ROS induces alterations and damage to macromolecules like lipids and proteins, most common phenomena being lipid peroxidation

Biochemistry of Free Radicals and Oxidative Stress The research was done by Sabry M. El-Bahr at the Department of Biochemistry, Faculty of Veterinary Medicine, P.O. Box 22758, Alexandria University, Egypt. The overall purpose of this experiment was to study the causes of oxidative stress that is caused by free radical. It is known that the free radicals and the Reactive Oxygen Species (ROS) are used interchangeably. ROS can damage DNA, biomembrane lipids, proteins and other macromolecules. The primary

Free radicals are groups of atoms, molecules, or ions that possess an unpaired/unshared valence electron in their electron orbitals. Due to this, many radicals are very reactive because they want to reach a stable state. They can be classified as oxidants or reductants depending on whether they accept electrons from other atoms or donate atoms. Free radicals can be produced by natural processes such as metabolism. They are also generated from foods that we eat, water, medication, etc. Free radicals

The applications of homogeneous photodegradation (single-phase system) to treat contaminated water, involves the use of an oxidant to generate radicals, which attack the organic pollutants to initiate oxidation. The major oxidants used are: •Hydrogen peroxide (UV /H2O2) •Ozone (UV /O3) •Hydrogen peroxide and Ozone (UV /O3/H2O2) •Photo-Fenton system (Fe+3 /H2O2) 1.2.1.4. Hydrogen peroxide The use of hydrogen peroxide as an oxidant brings a number of advantages in comparison to other methods of

mainly undergoes H-atom abstraction by free radicals (ȮH (42.7%), ĊH3 (22.8%), Ḣ (13%) and HȮ2 (4.4%)) to form methoxymethyl radical (CH3OĊH2). Subsequently, the methoxymethyl radicals (CH3OĊH2) readily dissociates

scientists are still learning about cancer and its effects, there is a lot of scientific evidence that points to free radicals as one of the

Cameron discounted social conditions such as poverty and unemployment as reasons for the 2011 riots, and focussed instead on criminality and morality ‘(Andrews, G. 2014). This essay will compare and contrast this conservative view of the riots with the radical view. A riot is an occasion involving violence directed at property, persons or authority. The current understanding of the term riot dates back to the fourteenth century, when it began to suggest violence and disorder among the population. By the
