Calcific aortic stenosis (CAS) is the most common valvular disease in Western countries. Histological findings in patients with CAS extremely resemble those of atherosclerosis and include accumulation and modification of lipoproteins, inflammation, extracellular matrix remodeling, and calcification. Angiogenesis is another prominent feature of CAS; however,(More)
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) has long been considered a classical glycolytic enzyme involved exclusively in cytosolic energy production. Several recent studies, however, have demonstrated that GAPDH is a multifunctional protein whose presence and activity can be regulated by disease states and/or experimental manipulation. Expression(More)
The purpose of this study was to evaluate the ability of aqueous extract of Aloe barbadensis Miller (Aloe vera) on oxidative damage and Anion Exchanger 1 (AE1, also known as Band 3) expression in human erythrocytes exposed to the water soluble free radical initiator 2.2’-azobis-2-amidinopropano dihydrochloride (AAPH). In addition, total phenolic compounds(More)
BACKGROUND Over the last decades, the role of oxidative stress in atherosclerosis has become well established, and considerable effort has been made to understand the mechanism of action of free radicals within the cardiovascular system. Conversely, relatively little attention has been directed towards the characterization of the antioxidant status of the(More)
OBJECTIVE The efficacy of biological sulphurous Bioglee on psoriasis was investigated using an organic matrix derived from the metabolism of microflora growing in shallow hyper thermal waters possessing high sulphur concentrations and in thermal mud at Guardia Piemontese-Acquappesa (CS). Such a matrix forms part of the "Sulphuretum" ecological matrix which(More)
AIM The T-type calcium channel is expressed in vascular endothelial cells, but its role in endothelial cell function is yet to be elucidated. We analysed the endothelial functional role of T-type calcium channel-dependent calcium under angiotensin II (Ang II) stimulation. METHODS Human umbilical vein endothelial cells were co-incubated with hormone at(More)
The main aim of this study was the investigation of the rheological properties of Red Blood Cells (RBCs) obtained from subjects admitted to blood donors, associated with the lipid profile of High-Density Lipoprotein Cholesterol (HDL-C), Low-Density Lipoprotein Cholesterol (LDL-C), Triglyceride (TG) and Total Cholesterol (TOT-C). The deformability index of(More)
Bigels are biphasic systems produced with an organogel (or oleogel) and a hydrogel mixed together at high shear rates. These systems are promising for different uses, among them the formulation of new cosmetic matrices for cosmetic agents delivery is under investigation. In the present paper, a common cosmetic formulation for skin care was enriched with(More)
Atherosclerosis of the internal mammary artery (IMA) is generally regarded as a rare (but existent) pathological entity with only a few cases reported in the most recent literature. The only study which to our knowledge has investigated the ultrastructural features of IMA atherosclerosis, demonstrate the presence of endothelial cells loss, defects of(More)
OBJECTIVE Psoriasis is a chronic skin disease and one of its main causes could be the oxidative stress. The use of natural reductants, in the treatment of several diseases, is well known but the effects of such treatments on the chronic psoriasis are not clear. The aim of this study is to evaluate the efficacy of the treatment with organic matrix, deriving(More)
