Ecological network analysis: an application to the evaluation of effects of pesticide use in an agricultural environment.

Ecological network analysis is used to evaluate the impact of pesticide use on ecological systems in the context of agricultural farmland environments. The aim is to provide support for the design of effective and minimally damaging pest control strategies. The ecological network analysis can identify species that are important to the integrity of the ecological network.

Isoelectric focusing of the human IgG light chains: a classification of the fractions and their normal values.

The method of isoelectrofocusing was employed to obtain a reproducible pattern of human IgG light chain bands. The map of IF spectra, which contained 13 main fractions and some subfractions, was delineated. Isoelectric points of these fractions and their quantitative relations in 10 healthy individuals were determined.
