3.1 Kinetic models and their dynamic behaviour in a nutshell Examples: Metabolic network; transport reactions; signaling system; gene expression Stoichiometric coefficients nir Stoichiometric coefficients denote the proportions, with which the molecules of substrates and products enter the biochemical reactions. One can summarise the stoichiometric coefficients in a matrix N. The rows refer to ...

We have performed a longitudinal study of the content of the putative neurotransmitter substances, enkephalin, dynorphin, and acetylcholine (ACh), in the cochlea of the Fischer 344 rat. It is the first study of transmitters in the rat cochlea over an extended time span. This study also provides biochemical verification of the presence of ACh in cochlear tissues. No change was seen in the cochle...

Humic substances are generally seen as important soil and natural water components. They are formed during humification of organic matter by soil microorganisms. Humic substances are a mixture of complex organic compounds that are usually separated into three fractions: humic acids, fulvic acids and humins. The properties of humate products on the market depend on the ratios between these fract...

Abstract The industrial metabolism has been conceived on the basis of analogies about set biochemical reactions (anabolism and catabolism) that occur in a living being their flows matter, energy substances natural ecosystems. This conception determines forms appropriation consumption substances, materials energy, from environment (natursphere) technical (technosphere) for transformation subsequ...

It was established that the water does not meet upper limit of 1st quality class according to DSTU 4808:2007 by all indicators except for chloride ions, SPAR and suspended substances. There is a decrease in level BSK5 at monitoring post lower part reservoir, which indicates entry substances into watercourse inhibit biochemical processes. also an increasing trend content sulfates, phosphates, ni...

The particular role of stress factors in pathology of bovine diseases has been observed. In many cases these factors have been estimated as main predisposing factors to infectious diseases [6]. Exposure to stress conditions (e.g. weaning, transport, remixing of animals, high temperature) has been associated with activation of the hypothalamic-pituitaryadrenal axis. The result of these processes...

Accepted for publication 30 March 1995 Introduction The age related amyloids have come of age. The increasing attention devoted to Alzheimer's disease in recent years has cast a spotlight on protein, the amyloid fibril protein associated with this disease. However, there is a multitude ofother age related amyloids which have been identified. In some instances, the fibril proteins have been iden...
