Immunochemical methods have been developed and placed on the market to analyze tetracycline residues (see Table 4). Thus, a qualitative EIA has been developed and used to analyze tetracyclines in honey samples with a detection level of 20 pg/kg-1 [96]. A microplate-based indirect ELISA has been developed to analyze tetracyclines using polyclonal antibodies. The assay could measure tetracycline in the range between 0.1 and 6 ng mL L Other tetracycline antibiotics such as chlortetracycline, rolitetracycline, or minocycline are also highly recognized in this assay [98]. Several immunoassay kits are commercially available for the analysis of tetracyclines although, to our knowledge, none of them... [Pg.213]

The permeability class boundary is based indirectly on the extent of absorption (fraction of dose absorbed, not systemic BA) of a drug substance in humans and directly on measurements of the rate of mass transfer across human intestinal membrane. Alternatively, nonhuman systems capable of predicting the extent of drug absorption in humans can be used (e.g., in vitro epithelial cell culture methods). In the absence of evidence suggesting instability in the gastrointestinal tract, a drug substance is considered to be highly permeable when the extent of absorption in humans is determined to be 90% or more of an administered dose based on a mass balance determination or in comparison to an intravenous reference dose. [Pg.553]

Power plants using fuel cells can now take the place of the present polluting coal or oil-based (indirect) electricity-producing plants. However, in a further development, it would be possible to extract COz from the atmosphere, and H2 from solar-driven electrolysis, to produce methanol with zero net injection of C02 into the atmosphere. These plants would at first ran on hydrogen from these fossil fuels, the attraction being the reduction of pollution and the increase in the conversion efficiency. To what extent the latter two commodities would be supplied from remote sites, or collected onsite at... [Pg.326]

Hospital databases may, however, be used for the establishment of reference values that are fuUy concordant with the IFCC recommendations." The requirement is that laboratory data be combined with information stored in clinical databases (i.e., to apply a direct sampling strategy instead of the distribution-based indirect method). Laboratory results are to be used as reference values only if stated clinical criteria are fulfilled. One may define criteria for selecting individuals who have a specified state of health or the disease for which reference data are necessary. Usually certain constraints are also imposed on the use of their laboratory results, such as allowing only one result of each analyte under study from each selected individual. Such reference values have one advantage over those based on direct sampling from other types of populations hospital-based reference values are ideal for the interpretation of results from hospitalized patients because they are produced under similar conditions. [Pg.428]

The electrostatic potential of pyridine outside the ring plane presents large negative regions with small minima (nearly equivalent) in correspondence with atoms C3-C5 and C4. It is not easy to find clear-cut examples of reactions involving the free base. Indirect evidence indicates that atoms C3-C5 are the most reactive. Nucleophilic substitution... [Pg.132]

The effect of most biotech drugs, however, is not mediated via a direct interaction between drug concentration and response systems, but frequently involves several transduction processes that include at their rate-limiting step the stimulation or inhibition of a physiologic process, for example, the synthesis or degradation of a molecular response mediator Kke a hormone or cytokine. In these cases, mechanism-based indirect response models should be... [Pg.163]

The concept of physiologically based indirect response models has been widely used in PK/PD modeling as far as the underlying physiological mechanism of drug action and observed effect are known. However, such an approach would definitely require more detailed information about the involved indirect response mechanism to provide valid, physiologically meaningful results when appUed to clinical data. [Pg.37]
