Growth of the body in early postnatal ontogenesis is associated with changes in the functioning of many systems, including the cardiovascular system. The circulatory system of newborns is characterized by numerous structural and functional features, which are manifested at the systemic level in significan...

Changes in cardiac and muscle activity during a fixed foreperiod in a simple reaction time taskThe present experiment was aimed at whether subjects, performing a forewarned simple reaction time (RT) task, do voluntarily tense agonist and antagonist muscles during the foreperiod; if so, would such...
For a muscle cell to contract, the sarcomere must shorten. ... When (a) a sarcomere (b) contracts, the Z lines movecloser together and the I bandgets smaller. The A band stays the same width and, at full contraction, the thin filaments overlap. What happens during muscle contraction?

摘要: Proliferation of cardiomyocytes and interstitial cells in the cardiac ventricle of the mouse during pre- and postnatal development was studied. Furthermore, the number of cardiomyocyte and interstitial cell nuclei per unit area was determined on histological sections....

Aging is a global challenge, marked in the lungs by function decline and structural disorders, which affects the health of the elderly population. To explore anti-aging strategies, we develop a dynamic atlas covering 45 cell types in human lungs, spannin
The cardiomyocyte-derived GFP+ EVs were also positive for intravesicular troponin I (cTnI) and muscle-associated glycogen phosphorylase (PYGM). This is the first direct demonstration that cardiomyocyte-derived EVs are present in the circulation and that the increased number of cardiac-derived EVs in ...
