objective: endothelium is a selective and permeable membrane for transferring nutrients and vital components to arterial wall. endothelial damage might lead to altered biological function of endothelium and clinical consequences such as atherosclerosis. blood pressure pulse always exerts circumferential tension to the arterial wall. hence, such tension together with other loads, play important ...

Patients with antiphospholipid antibodies (APLAs) are at increased risk for arterial and venous thrombosis. Many APLAs associated with these events react with 2 glycoprotein I ( 2GPI), and endothelial cell reactive antibodies that activate endothelial cells in a 2GPI-dependent manner occur commonly in these patients. We previously reported that 2GPI binds with high affinity to annexin A2 on the...

The binding of heparin or heparan sulphate to a variety of cell types results in specific changes in cell function. Endothelial cells treated with heparin alter their synthesis of heparan sulphate proteoglycans and extracellular matrix proteins. In order to identify a putative endothelial cell heparin receptor that could be involved in heparin signalling, anti-(endothelial cell) monoclonal anti...

BACKGROUND It has previously been shown that IgG antibodies from patients with limited cutaneous systemic sclerosis (SSc) bind to specific microvascular endothelial cell antigens. Since patients with limited cutaneous SSc are prone to develop pulmonary arterial hypertension (PAH), and since endothelial cell activation is involved in the pathogenesis of idiopathic PAH (IPAH), a study was underta...

background: alzheimer’s disease (ad) is a progressive neurodegenerative disease and nowadays the role of endothelial cell (ec) injury has been proposed in pathological process in ad. peroxisome proliferator‑activated receptor‑γ (ppar‑γ) agonist has anti‑inflammatory properties through activation in glial cells and improves vascular function and prevent atherosclerotic disease progression. the a...

purpose: to compare corneal endothelial cell features after cataract surgery performed using fixed torsional or conventional (pulse) ultrasound mode. methods: in this randomized comparative study, 60 eyes were randomly and equally divided into two groups of torsional or longitudinal mode phacoemulsification. all surgeries were performed by an experienced surgeon, and the outcomes were evaluated...

to evaluate corneal endothelial cell changes after intravitreal and subconjunctival injection of avastin (bevacizumab) based on specular microscopic findings.  this prospective interventional study was performed on 82 eyes of 82 patients. forty-two cases with ptrygia received a subconjunctival injection of bevacizumab (2.5mg/0.2ml) and 40 diabetic subjects with retinal neovascularization or mac...

background: angiogenesis, the formation of new blood vessels from preexisting ones, is one of the most important physiological and pathological processes occur in the body. in the pathological conditions such as tumor growth, psoriasis, corneal neovascularization and rheumatoid arthritis, angiogenesis is crucially required for the devolopment of the disease. zataria multiflora as a member of la...
