In cardiac muscle
, however, the increased cellular Ca concentration does not greatly exceed the on-off trigger level of 1 uM, and it always remains around this level despite the all-or-none nature of electrical signals given by pacemaker cells, although the reason behind this is unclear.
200-300 mg of leg muscle, breast muscle, cardiac muscle
, abdominal fat and liver were sampled and stored at -70[degrees]C for extraction of total RNA.
A group of Japanese scientists said Wednesday they have developed rat cardiac muscle
that automatically beats outside the body from heart muscle cells of newborn rats and improves the functions of a rat's heart when transplanted, the first such advances in the world.
1A), CK-MB in cardiac muscles
was detected in the patient sample, but its activity was substantially reduced.
Toshiki was diagnosed with dilated cardiomyopathy, a condition in which cardiac muscles
are weakened and cannot pump effectively, after he was hospitalized in August last year with breathing problems.
The machine is used to monitor heart patients, check-ing on valves, cardiac muscles
Their theory comes after revelations that the hard training to stay at the top of the game enlarges hearts and thickens cardiac muscles
More is known about skeletal and cardiac muscles
because patterns of striations, or alternating dark and light bands, on these muscle fibers have enabled scientists to study the movement and alignment of the protein strands, called myosin and actin, which do the work of contraction inside the cell.
The technique, developed by researchers from the University of Jaen (Spain), the University of Granada, the Hospital ClA-nico Universitario of Malaga and the University of Bath (United Kingdom), could be used in the future for regeneration of cardiac muscles
through the use of cells directly extracted from the patient.
Kiva Humphries, 16, picked up an infection last February which seriously damaged her cardiac muscles
Embryonic stem cells, believed to be capable of generating nerves, cardiac muscles
and liver tissue, are expected to play a crucial role in helping regenerate damaged organs and tissue but research on such cells could also pose some ethical concerns, should they involve, for instance, the destruction of embryos.
