Two distinctive features stand out: The mode of CO2 concentration in diatoms is still largely unclear, as well as the post-translational regulation of photosynthetic products.
Toxicologists define "interaction" as departure from a model based on mode of action: concentration addition (CA; for similarly acting compounds) or independent action (IA; for compounds that act differently).
Consistent with a caspase-specific mode of action, concentrations of up to 94 μM failed to protect yeast against Bax-induced lethality.
The influence and interaction effects of the most important variables in the oxidative process (concentration and addition mode of hydrogen peroxide, concentration and type of catalyst, pH, reaction period and presence/absence of light) were investigated.
The outcome of CD40 ligation will depend on several factors including ligand concentration, mode of presentation, receptor density, and the activation of NFkB-dependent survival factors [23], [24].
Which finally bring us back to Constant Lambert: in situating his symphony in this mode of slow, reflective concentration, Vaughan Williams risked forfeiting this piece's "symphonic" credentials.
The factorial analysis showed that for the batch mode of operation, oil concentration, detention time, coagulant use, and water type had a significant effect on PHC removal.
Denaturing gradient gel electrophoresis (DGGE) analysis indicated that the structure of microbial community was influenced by the mode of operation, COD concentration and cell immobilization methods of the MFC.
It is clear that uncommitted, peripheral naïve CD4+ T lymphocytes can differentiate into Tregs based on mode of stimulation, antigen concentration and cytokine milieu [27].
Given default assumptions of common mode of action and concentration addition (Lambert and Lipscomb 2007), the relative potency of each insecticide could then be used to estimate the joint toxicity of chemicals in a mixture using a conventional toxic unit approach (Junghans et al. 2006).
