Ultrastructural Cytochemistry
Selective extraction of specific cell components by enzyme or acid hydrolysis is possible from ultrathin sections for electron microscopy and parallel 2 micro sections for light microscopy of tissues fixed in formalin and embedded in a water-soluble polyepoxide, product X133/2097. Normal rat tissues fixed 15 minutes in formalin at 3 degrees C are more rapidly digested by proteinases than those ...
متن کاملBiogenic amines in sea products
Sea food products are being processed through various techniques, i.e. chilling and freezing, heating, irradiating, and curing; regard to the condition of processing, formation of biogenic amines are probable, as raw materials are usually rich in respective precursors. Fermented fish products are among the most vulnerable items to this challenge, these products due to their nutritious value are...
متن کاملBiogenic Amines
Examples of G-protein-coupled receptors that can be biochemically detected in homoor heteromeric complexes are emerging at an accelerated rate. Biophysical approaches have confirmed the existence of several such complexes in living cells and there is strong evidence to support the idea that dimerization is important in different aspects of receptor biogenesis and function. While the existence o...
متن کاملREVIEW Biogenic Amines in Food
Recent trends in food security are promoting an increasing search for trace compounds that can affect human health. Biogenic amines, the so-called natural amines with physiological significance, belong to this group of substances. Their amounts are usually increased during controlled or spontaneous microbial fermentation of food or in the course of food spoilage. Several methods exist for isola...
متن کاملEditorial: Biogenic amines in foods
Biogenic amines (BA) are nitrogenous compounds of low molecular weight and are essential at low concentrations for natural metabolic and physiological functions in animals, plants, and microorganisms. Histamine, putrescine, cadaverine, tyramine, tryptamine, 2-phenylethylamine, spermine and spermidine are the most important BA in foods in which they are mainly produced by microbial decarboxylati...
