Injury to the tunica media initiates atherogenesis in the presence of hyperlipidemia [PDF]
Frontiers in Cardiovascular Medicine, 2023 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

Decreased collagen VI in the tunica media of pulmonary vessels during exposure to hypoxia: a novel step in pulmonary arterial remodeling [PDF]
Pulmonary Circulation, 2019 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.

A cell-based mechanical model of coronary artery tunica media. [PDF]
J R Soc Interface, 2017 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.

Protective Role of Hesperidin Against Deltamethrin-Induced Cardiovascular Structural Damage: Involvement of Caspase-3-Driven Apoptosis and Fibrosis Suppression in Rats [PDF]
Journal of Cardiovascular Development and DiseaseBackground and Objectives: Deltamethrin (DLM), a widely used pyrethroid insecticide, has been linked to cardiotoxic effects in non-target organisms. Hesperidin (HSP), a dietary bioflavonoid with antioxidant and cardioprotective properties, may counteract
