Changes described in the muscle cells are interpreted as being consistent with a high level of secretory activity in the early stages, but later they more resemble a degenerative change.doi:10.1038/icb.1962.40Kathryn N HamThe Australian journal of experimental biology and medical science...
What is the aortic semilunar? The aortic semilunar valve is a valve found in the human heart. It is defined as a crucial gate found in the heart found between the left ventricle chamber of the heart and the aorta. It makes blood flow in one direction from the left ventricle to the aort...
Our study thus provides new insights into the development and heterogeneity of the mammalian cardiac conduction system by revealing a new cardiomyocyte population with potential catecholaminergic endocrine function.Similar content being viewed by others The G4 resolvase Dhx36 modulates cardiomyocyte ...
Type II is only present at the embryonic stage. Biochemical studies on Type I collagen show that it possesses a higher level of glycosylation of the hydroxylysine residues than Type I in other tissues. It has been suggested that the extent of glycosylation may control the size of the fibres ...
The Structure and Function of the Heart, this section explains the structure and functions of the heart, for A-Level Biology Revision.
The heart was quickly excised preserving a part of aorta and placed into filtered (0.45 μm) aerated isolation medium (IM) of the following composition: 117 mM NaCl, 5.7 mM KCl, 4.4 mM NaHCO3, 1.5 mM KH2PO4, 1.7 mM MgCl2, 11.7 mM glucose, 11 mM Cr, 20 mM taurine, 10 mM ...
When blood exits the left ventricle, there are many branches that divide off from the aorta to supply blood throughout the body. Coronary arteries supply the outer muscle tissue of the heart with blood. As the aorta continues, the carotid arteries carry blood toward the brain and the abdominal...
Regulation of calcium channel activities are also provided by alternative splicing of the subunits. To elucidate the genomic organization of the VDCC 3 subunit gene, two genomic clones were isolated from human genomic liabrary using the whole rat cDNA for 3 subunit as a probe. The 3 subunit ...
LP offspring exhibited a 40% reduction in the amount of elastic fibers in the aorta wall compared with NP offspring (p <0.01), and the quantity of elastic fibers was not altered by rosiglitazone. The smooth muscle cells, elastic lamellae, cir- cumferential wall tension (CWT) and tensile ...
