ABSTRACT There is constant low level background radiation from the cosmos but in certain situation the body may be subjected to increased acute or chronic exposure from other sources. This occurs in situations such as radiation accidents, medical use and could possibly occur in military/terrorist incident. Dependent on the type, strength of the actual source, degree of exposure and type of radiation different strategies may be employed to reduce damage to the body tissues. A number of pharmacological agents such as peroxisome proliferator-activated receptor (PPAR) gamma agonists, diltiazem, amifos...

Solís-Arias Affiliation(s) Human Photosynthesis ® Study Center, Aguascalientes, México . ABSTRACT Mitochondrial disease has important implications for numerous functions that affect different cells lines and tissues. The mitochondrion is an organelle that draws much attention from researchers, but their study is hampered by changing in number, size, shape, and location among other things. To date, it is not understood if mitochondrial alterations could be considered to be downstream effects or are the root causes of diseases classified as neurodegenerative. It is an unresolved enigma if mitochondrion form, size, location, and number become crucial to the correct functioning of distinct cells lines and tissues, besides the role of reactive oxygen species (ROS)...
