Determination of Dissolved Oxygen in Photosynthetic Systems and Protective Strategies Against its Tls are ordinarily exposed only to ambient O. levels and often far below, the oxygenic photosynthetic cell produces its own oxygen from within. The O. concentrations to which photosynthetic organisms are exposed, are often above those in the ambient air. Moreover, the energy utilized by the photosynt

The Superoxide-Generating NADPH Oxidase of White Blood Cells,ygen to the tissues and carbon dioxide from the tissues to the lungs, are much the most abundant. The white blood cells (or leucocytes) make up about 0.1% of the cells of blood and are largely involved in the processes of identifying and killing infecting microorganisms (Table 1). As indicated in Ta

Role of Reactive Oxygen Species and Lipid Peroxidation in Chemically Induced Toxicity and Carcinogede (H.O.), hydroxyl radical (HO) and singlet oxygen (.O.) have been proposed as playing important roles in the toxicity of various chemical agents. Some examples are given in Table 1. Their role is, however, highly controversial and, dependent on your point of view, can be considered as being either

It is becoming apparent that most agents exhibit several parallel pathways or effects on sensitive cell targets which include nucleic acids, certain proteins and

Oxidative and Peroxidative Damage and its Role in the Aging Process,onmental challenges. This phenomenon can be associated with the accumulation of alterations in structure, composition and function of cells, tissues and organs of multicellular organisms. Aging organisms thus characteristically exhibit a time-associated increase in the propensity to die. Death ensue

There are many naturally-occurring photodynamic sensitizers that can cause harm to humans, mammals, or plants: for example, porphyrins from blood or chlorophyll, the plant toxin hypericin, the fungal pigment cercosporin, and several polyacetylene derivatives.
