A method based on the application of ultra-performance liquid chromatography (UPLC) coupled to hybrid quadrupole-time-of-flight mass spectrometry (QqTOF-MS) with an electrospray (ESI) interface has been developed for the screening and confirmation of several anionic and non-ionic surfactants: linear alkylbenzenesulfonates (LAS), alkylsulfate (AS),(More)
BACKGROUND The natural tetrapeptide acetyl-Ser-Asp-Lys-Pro (AcSDKP), generated from thymosin beta4 following its cleavage by prolyl oligopeptidase (POP), is a physiological stimulator of angiogenesis. Because of the critical role of neovascularisation in tumor development, the expression of AcSDKP and the activity of POP were examined in different human(More)
Little is known about the glycosylation of the isotype switched B cell receptor (BCR) in multiple myeloma, and the way it might affect receptor function. In this work IgG BCRs isolated from the individual lysates of peripheral blood lymphocytes (PBL) of 32 patients with IgG multiple myeloma and healthy controls were investigated for the expression of sialic(More)
BACKGROUND Altered glycosylation of immunoglobulin G (IgG) has been found to affect certain immunological activities of IgG and to correlate with increased inflammation in various disease states. This work deals with the changes in distribution and galactosylation of IgG subclasses present in saliva and gingival crevicular fluid (GCF) of patients with(More)
INTRODUCTION Mesenchymal stem cells (MSCs) are a promising tool for regenerative medicine, but due to the heterogeneity of their populations, different sources and isolation techniques, the characteristics defining MSCs are inconsistent. OBJECTIVE The aim of this study was to compare the characteristics of MSCs derived from two different human tissues:(More)
The present study evaluated the role of interleukin (IL) 17 in multilineage commitment of C2C12 myoblastic cells and investigated associated signaling pathways. The results concerning the effects on cell function showed that IL-17 inhibits the migration of C2C12 cells, while not affecting their proliferation. The data regarding the influence on(More)
BACKGROUND/AIM Diabetic nephropathy (DN) as a major microvascular complication of diabetes mellitus (DM) include a progressive increase in urinary albumin excretion in association with an increase in blood pressure and to end stage renal failure. Hypertension connected with renin-angiotensin system (RAS) hyperactivity and corresponding genotypes,(More)
The mouse is a suitable experimental model to study the biology of mesenchymal stem cells (MSCs), as well as to be used in biocompatibility studies and tissue engineering models. However, the isolation and purification of murine MSCs is far more challenging than their counterparts from other species. In this study, we isolated, expanded and characterized(More)
The effects of monoclonal antibodies (mAbs) to cell-surface molecules, divalent cations, and various cell-signaling and metabolic inhibitors on the binding of thymocytes to rat thymic dendritic cells (TDC) were studied using a rosette assay. It was found that TDC/thymocyte adhesion was stronger and faster at 37 degrees C than at 4 degrees C. Flow cytometric(More)
INTRODUCTION Our study was aimed at determining whether the polymorphism of genes for different components of the renin-angiotensin-aldosterone system could influence the renal hemodynamic response to losartan treatment. MATERIAL AND METHOD The study included 35 patients with type I diabetes mellitus and persistent albuminuria, genotyped for the 1166 A/C(More)
