A model of signal transduction from the perspective of informational thermodynamics has been reported in recent studies, and several important achievements have been obtained. The first achievement is that signal transduction can be modelled as a binary c... see more

The literary sources relating to the methods for obtaining polycyclic compounds with pyridopyrimidine and pteridine subunits have been systematized and analyzed. The synthetic potential of two main approaches to the processes of formation of these types o... see more

Aim. To develop the preparative methods for obtaining new series of biologically active substances by the three-component interaction between isatin, a-amino acids and N,N’-di(3-carboxypropenoyl)-1,2-ethylenediamine and determine the structure of the comp... see more

Entomopathogenic nematodes (EPN) are ubiquitous and generalized consumers of insects in soil food webs, occurring widely in natural and agricultural ecosystems on six continents. Augmentative releases of EPN have been used to enhance biological control of... see more

Biological control can be considered an intentional induction of a trophic cascade, whereby the addition of herbivores' natural enemies or other habitat manipulations effectively enhance natural enemy populations, lead to reduced herbivore populations or ... see more

During the last decade, the combination of different metal- and bio-catalyzed organic reactions in aqueous media has permitted the flourishing of a variety of one-pot asymmetric multi-catalytic reactions devoted to the construction of enantiopure and high... see more

The present article describes the synthesis of new 4,4-spiroalkenic 1,2-diarylpyrazolidine-3,5-diones by ring-closing metathesis reactions (RCM). They may be potential biological active compounds since a great quantity of 1,2-diazoles show a wide spectrum... see more

The use of entomopathogenic nematodes (EPN) for management of the root weevil, Diaprepes abbreviatus, in Florida citrus groves is considered a biological control success story and typically involves augmentation in which EPN are applied inundatively as bi... see more

Active forms of oxygen are formed in the course of the organism's vital activity in biochemical reactions. These forms, when the pro/antioxidant balance is disturbed, trigger a cascade of lipid peroxidation, which can be the cause of the development of va... see more
