For each of these harmful organisms different absorption, distribution, metabolism and excretion routes have to be considered leading to quite different physicochemical properties of lead compounds.
In organisms the absorption, distribution, metabolism, excretion, and toxicity of CNTs depend on the inherent physical and chemical characteristics such as CNT functionalization, coating, length, and agglomeration state that are influenced by the external environmental conditions during CNT production, use, and disposal stages.
Although infections with Cryptosporidium parvum can be asymptomatic, even when it does not cause diarrhea, this organism affects absorption of nutrients and has a negative effect on weight gain of children (Checkley et al., 1997).
The main function of the transmembrane light-harvesting complexes in photosynthetic organisms is the absorption of a light quantum and its subsequent rapid transfer to a reaction center where a charge separation occurs.
The coordinated action of the product of these genes at organism level supports absorption, distribution, metabolism, and excretion of foreign compounds, thus controlling drug exposure.
Bioconcentration is the process by which a chemical is retained in an aquatic organism following its absorption through respiratory and dermal surfaces from the surrounding water (does not include dietary exposure).
Multinomial logistic regression will be used to explore the association between the three-level outcome variable (treatment failure, treatment success, re-infection) and risk factors such as the impact of organism load, azithromycin absorption and MIC.
Because homeostatic mechanisms regulate manganese concentration in the organism, notably low absorption levels and a high rate of presystemic elimination by the liver (Roth 2006), it is generally believed that the oral route poses no significant toxic risk (Boyes 2010).
Extinction events and selection pressures gave rise to many critical evolutionary steps on Earth: DNA absorption, eukaryotic organisms, multicellularity, and sexual reproduction, among others.
For the most part, the distribution and accumulation of surfactants in organisms depends on their absorption at biological interfaces and is affected by metabolism and excretion.
