Abstract
The vascular endothelium plays a pivotal role in regulating vascular homeostasis. Blood flow exerts several mechanical forces on the luminal surface of the Endothelial Cell (EC) including pressure, circumferential stretch, and shear stress. It is widely believed that shear stress plays a central role in regulating EC inflammatory responses and the pathogenesis of atherosclerosis. High shear stress can induce an antiinflammatory status in EC, which is partially mediated by the production of proteins and transcription factors able to suppress different proinflammatory signalling pathways. In this review, we summarise the available evidence regarding the effect of shear stress on vascular EC and smooth muscle cells, the regulation of MAPK and NF-κB including the production of different negative regulators of inflammation such as MKP-1 and NRF2, and the production of microRNAs. We also discuss the possible links between shear stress and the development of atherosclerosis.
Keywords: Shear stress, endothelium, vascular inflammation, atherosclerosis, macrophages, signalling pathway, microRNAs.

Ischemic Cardiovascular Diseases: Mechanisms, Diagnosis and Therapy
Ischemic cardiovascular disease includes myocardial infarction, coronary atherosclerotic heart disease, angina pectoris, etc., constitute the leading cause of patient mortality by preventing tissues from getting sufficient oxygen and nutrients. Ischemic heart disease, as a clinical condition, is characterized by myocardial ischemia, causing an imbalance between myocardial blood supply and demand, ...read more
TREATMENT OF CARDIOVASCULAR DISEASE IN CHRONIC AND END STAGE KIDNEY DISEASE
Cardiovascular disease still remains the leading cause of death in Chronic and End Stage Kidney Disease, accounting for more than half of all deaths in dialysis patients. During the past decade, research has been focused on novel therapeutic agents that might delay or even reverse cardiovascular disease and vascular calcification, ...read more
