No doubt, the immune system provides very much for the organism survival. It was shown that the immune response of the young partners that dropped during parabiosis with the old ones did not recover during 7 months of the following independent life (Butenko, 1986). 

However, even after all traces of Berzelius s ideas on vitalism had been disproved by experiment, his associated term organic survived.- After Wohler had shown thathumans as well as organisms could make organic chemicals, the term organic chemistryhecame the chemical study of any carbon-based compounds, and that usage remains. 

Perform resistance testing on all Gram-positive spore formers. Submit any organism surviving the resistance test for D-value determination. 5. Summarize stopper and vial data separately. 

Spore bioburden data are collected to screen for heat-resistant organisms. Organisms surviving heat-resistance testing are to be submitted to the terminal sterilization laboratory for D-value analysis. D-values are then compared to established models for the component sterilization process.

Laboratory test organisms should be representative of the four groups microorganisms, plants, invertebrates, and fish. The results are often reported as a lethal dose or concentration (LD or LC) with LCS0 the concentration where 50 % of the test organisms survived. The effective dose or concentration (ED or EC) is defined analogously where EC50 is used... 

Validation of a sterilization process differs from validation of a nonaseptic process in several significant ways. A sterilization process is a treatment process from which the probability of any micro-organism survival is less that 10 6, or one in a million. Sterility means the absence of all life. Aseptic means the absence of pathogenic organisms. The difference between nonaseptic and aseptic process validation is that the aseptic process includes at least one measure that is intended to remove pathogens.

The advent of cyclosporine revolutionized organ transplantation by prolonging organ survival. 

The behavior of some reproducing system will change in the very moment when a former resource turns into a sink for the same - essential or non-essential - element, e.g. by biogeochemical changes in the area. In either case further existence or at least the ability of the species/population to keep on reproducing are jeopardized. Effects in population structure can be anticipated even if aU the individual organisms survive at first. 

From the preceding discussions, it is evident that only a small proportion of the silica originally fixed by marine organisms survives dissolution to be incorporated into the geologic record. Recent estimates of the fraction ultimately preserved in marine sediments range from 2 to 0.05% (Hurd, 1973 Heath, 1974, Wollast, 1974) and Heath (1974) considers that 85 to...
