Обобщены результаты исследований эффектов g-облучения (0,25-1,0 Гр; 100-350 мР/ч) на биоэлектрическую активность кардиомиоцитов, биомеханическую функцию миокарда, сократительные и дилататорные реакции аорты, механизмы нейрогормонального контроля сердца и сосудов. Выявленный неспецифический характер эффектов малых доз, приводящий к функциональным изменениям в сердце и сосудах, может быть основой для возникновения предпатологических и патологических состояний.
A multitude of physical and bio-chemical processes take place during autolysis, including ATP break-up (dephosphorylation) that leads to glycogen phosphorylation, intensive accumulation of myofibrillar proteins, concentration of lactic (and phosphorous) acids that affect the state of muscle proteins. This, in turn, affects the technological properties of meat. Histological examination of the longest back muscle of pigs showed a distinct cross-striation of muscle fibers. Histological examination of the longest back muscle of pigs showed a distinct cross-striation of muscle fibers. During autolysis, micro-cracks appeared with minor breaks in sarcolemma, and only some muscle fibers areas had contraction nodes. During autolysis, micro-cracks appeared with minor breaks in sarcolemma, and only some muscle fibers areas had contraction nodes. Raw meat, which was classified as DFD (dark, sticky) according to the quality criteria, had a different structure. Cross-section of its fibers were ro...
