Injury to the tunica media initiates atherogenesis in the presence of hyperlipidemia. [PDF]
Background and aimsFatty streaks initiating the formation of atheromatous plaque appear in the tunica intima. The tunica media is not known to be a nidus for lipid accumulation initiating atherogenesis. We assessed changes to the tunica media in response to a micro-injury produced in the pig aorta.

Tunica intima compensation for reduced stiffness of the tunica media in aging renal arteries as measured with scanning acoustic microscopy. [PDF]
AbstractObjectivesAging causes stiffness and decreased function of the renal artery (RA). Histological study with light microscopy can reveal microscopic structural remodeling but no functional changes. The present study aimed to clarify the association between structural and functional aging of the RA through the use of scanning acoustic microscopy ...

A cell-based mechanical model of coronary artery tunica media. [PDF]
A three-dimensional cell-based mechanical model of coronary artery tunica media is proposed. The model is composed of spherical cells forming a hexagonal close-packed lattice. Tissue anisotropy is taken into account by varying interaction forces with the direction of intercellular connection.

Structural Features in Tunica Media of the Aorta in Lamb
In blood vessels situated just after the heart, an irregular blood flow occurs due to some specific structural elements of the tunica media. The current paper describes the histological aspects of some post-cardiac arterial sections in lamb. The tissue samples were collected from five 30 days old male lambs (Țurcană breed).

Immune cells and vasa vasorum in the tunica media of atherosclerotic coronary arteries. [PDF]
In coronary artery disease (CAD), the disruption of the tunica media immune privilege manifests as increased leukocyte infiltration and the formation of vasa vasorum. We aimed to characterize the immune privilege status of the tunica media in human coronary arteries (CAs) with atherosclerotic plaques, by comparing the abundance and composition of ...

Decreased collagen VI in the tunica media of pulmonary vessels during exposure to hypoxia: a novel step in pulmonary arterial remodeling. [PDF]
The development of hypoxic pulmonary hypertension is characterized by the structural remodeling of pulmonary arteries. However, the relationship between changes of arterial cells and the extracellular matrix remains unclear.

Tunica media remodeling in mesenteric arteries of hypertensive rats [PDF]
The tunica media of the vascular wall is a composite material comprised of smooth muscle cells and fibrous and nonfibrous matrix proteins.Using morphometric techniques, this study quantifies the cell and matrix composition of normotensive (Wistar-Kyoto) and spontaneously hypertensive rat mesenteric arteries.The data show that the superior mesenteric ...

Vasa Vasora in the Tunica Media of Goat Aorta [PDF]
El objetivo de este estudio fue describir la distribucion de vasa vasora en la tunica media de diversas partes de la aorta de cabra, ya que esto influye en las propiedades fisicas y la aparicion de enfermedades. Las muestras se obtuvieron de 16 cabras machos adultos sanos (Capra hircus) desde la porcion ascendente del arco aortico, segmentos toracicos ...

Cellular Heterogeneity of the Vascular Tunica Media [PDF]
Following arterial injury in adult humans and other mammals, there occurs a thickening of the intimal layer of the vessel wall due to migration of cells from the tunica media and proliferation of these migrated cells, along with any resident intimal cells.
