Photophysiology Current Topics In Photobiology And Photochemistry

Photophysiology: Current Topics in Photobiology and Photochemistry, Volume VIII is a collection of papers that discusses the photobiological phenomena of plants. This collection presents comparative studies on photosynthesis blending at the molecular, cellular, and plant levels. Some papers also analyze the photosynthesis in the green algae by using genetic methods, as well as the physical separation of photosynthetic system I from system II. One paper discusses the role of cation fluxes in chloroplast activity, including the measurement of ion fluxes in organelle suspensions. Another paper investigates the inter-relationships of photosynthesis and nitrogen fixation in a photosynthetic bacteria. One paper reviews the electrical activities of individual cells and describes the techniques of recording evoked potentials or the minute electrical signals produced from sensory stimuli that are recordable from electrodes attached on the human scalp. One paper considers the inhibitory effects of blue light and near-ultraviolet radiation on the growth and respiration of some organisms. Bio-chemists, photobiologists, photochemists, and researchers involved in plant biology and photophysiology will find this volume highly informative and challenging.

Photophysiology: Current Topics, Volume IV focuses on various topics in photophysiology, including photochemistry, pyridine nucleotide-linked systems, and bioluminescence. The selection first elaborates on photochemistry and vision, photoperiodism in insects, and response of human skin to ultraviolet light. Discussions focus on clinical photopathology, chronic effects of ultraviolet radiation on human skin, optics of the skin, spectral sensitivity, interaction of photoperiod with other environmental variables, effects of high-intensity radiation, human cone pigments, and effect of light. The text then ponders on cellular recovery from photochemical damage and a physical approach to bioluminescence. Concerns cover theoretical background for excited states, results and interpretation of mechanism, biological consequences of photochemical events, reconstruction of damaged DNA, and physiological and environmental effects on repair and recovery. The book takes a look at the enzymic aspects of bioluminescence, including pyridine nucleotide-linked systems, peroxidation systems, and simple enzyme-substrate systems. The selection is a dependable reference for researchers wanting to study photophysiology.
