The human breast is likely exposed to Al (aluminium) from many sources including diet and personal care products. Underarm applications of aluminium salt-based antiperspirant provide a possible long-term source of exposure, especially after underarm applications to shaved and abraded skin. Al research in breast fluids likely reflects the intraductal(More)
We evaluated the effects of the glycosaminoglycan sulodexide (SDX; antithrombotic/profibrinolytic drug) on the activity and release of matrix metalloproteinases (MMPs) in human blood. This was a prospective non-randomized study, analyzing by zymography and ELISA the in vitro effects of SDX on pro-enzyme, complexed, and active MMP forms in plasma and serum(More)
UNLABELLED Injection of the LP-BM5 murine leukemia virus into mice causes murine AIDS, a disease characterized by many dysfunctions of immunocompetent cells. To establish whether the disease is characterized by glutathione imbalance, reduced glutathione (GSH) and cysteine were quantified in different organs. A marked redox imbalance, consisting of GSH(More)
Breast cancer, a worldwide disease with increasing incidence, develops from ductal/lobular epithelium. Nipple aspirate fluid (NAF), secreted from the breast ducts and lobules, can be analyzed to assess metabolic activity in breast microenvironment. Premalignant and malignant cell alterations may produce biochemical signals that deliver inflammatory proteins(More)
Glycosaminoglycans (GAGs) from breast cyst fluid (BCF) of gross cysts, subdivided into apocrine and flattened, directly collected from 27 gross-cystic-breast-disease (GCBD)-affected women were analysed. Heparan sulfate, not further investigated, and chondroitin sulfate were identified. This last polysaccharide, in a content of 25-27 µg ml(-1) BCF and having(More)
One of the major goals in cancer research is to find and evaluate the early presence of biomarkers in human fluids and tissues. To resolve the complex cell heterogeneity of a tumor mass, it will be useful to characterize the intricate biomolecular composition of tumor microenvironment (the so called cancer secretome), validating secreted proteins as early(More)
Traditional technologies to investigate system biology are limited by the detection of parameters resulting from the averages of large populations of cells, missing cells produced in small numbers, and attempting to uniform the heterogeneity. The advent of proteomics and genomics at a single-cell level has set the basis for an outstanding improvement in(More)
Inflammation represents an important epiphenomenon in the etiopathogenesis of chronic venous disease, a worldwide debilitating condition affecting millions of subjects. The pathophysiology of chronic venous disease (CVD) is based on the hemodynamic abnormalities in conjunction to alterations in cellular and extracellular matrix biocompounds. The endothelial(More)
Chronic venous disease represents a healthcare problem due to high prevalence and recurrence rates. Studies on chronic venous ulcer wound fluid (CVUWF) have demonstrated increased inflammation and proteolysis which can cause tissue destruction and delayed healing. This review discusses: nearly all known metabolites discovered in the past 25 years in CVUWF(More)
Chronic venous disease (CVeD) is a debilitating condition that affects millions of individuals worldwide. The condition can result in varicose veins, or advance to severe skin changes and venous ulceration. The fundamental basis for CVeD is inflammation within the venous circulation and that it is subjected to increased hydrostatic pressure resulting in(More)
