Shear Bond Strength of Orthodontic Brackets Bonded with Thermo-Cured Glass-Based Materials-An In Vitro Study.

The results of orthodontic therapy largely depend, among other factors, on the preparation of the tooth enamel itself and the choice of material used to bond orthodontic brackets. The aim of this in vitro study was to determine the shear bond strength (SBS) and adhesive remnant index (ARI) score of thermo-cured glass-ionomers on different pretreated enamel, in comparison with the commonly used composite cement. Three commercially available nano-ionomer or highly viscous glass-ionomer cements (EQUIA Forte Fil, EQUIA Fil, Ketac Universal) and two types of compo-sites (Heliosit Orthodontic, ConTec Go!) were investigated in this study.

Effect of Granzyme K, FasL and Interferon-γ Expression in Placentas with Preeclampsia.

This study aimed to investigate the cytotoxic activity of decidual lymphocytes and the mRNA/protein expression of cytotoxic proteins in various cell types in the context of preeclampsia (PE) compared to those of healthy pregnancies. We analyzed fresh decidua basalis tissue and tissue embedded in paraffin (FFPE) from PE pregnancies (n = 15) and compared them with those of healthy pregnancies (n = 15) of the corresponding gestational age. Using double immunofluorescence staining, we observed differences in the intensity and distribution of staining for granzyme K (GZMK) and FasL in extravillous trophoblasts.

A relation of serum homocysteine, uric acid and C-reactive protein level in patients with acute myocardial infarction.

Aim To determine the relationship of homocysteine (HCY), uric acid (UA) and C-reactive protein (CRP) in serum of patients with acute myocardial infarction (AMI) prior to application of percutaneous coronary intervention (PCI) and their level of correlation in serum of patients with normal and elevated CRP (predictor of worse cardiovascular outcomes). Methods The study involved 85 patients with diagnosed AMI. Before the PCI, venous blood samples were taken into the vacuum test tubes.

Levels of Nitric Oxide Metabolites and Myeloperoxidase in Subjects with Type 2 Diabetes Mellitus on Metformin Therapy .

Introduction: Endothelial dysfunction is involved in the pathogenesis of insulin resistance, diabetes mellitus type 2, diabetic complications and preceded clinical manifestation of cardiovascular complications. Increased myeloperoxidase activity has been linked to a number of pathologies with compelling evidence in initiation and progression of inflammatory events. The aim of this study was to compare concentrations of metabolite nitric oxide and myeloperoxidase in the plasma of diabetes mellitus type 2 patients on metformin therapy, without clinical signs of cardiovascular disease and healthy subjects, as well as evaluation of concentrations of analytes in association with glycemic control.

Kappa Free Light Chains in Cerebrospinal Fluid of Patients with Identified Oligoclonal Immunoglobulin G.

Background: Production of kappa free light chains (KFLC) represents a part of humoral immune response, along with the synthesis of intrathecal immunoglobulins. Increased concentrations of immunoglobulin G light chains, kappa and lambda chains, were identified through research of numerous diseases of central nervous system. The qualitative method of isoelectric focusing (IEF) followed by immunofixation currently represents the accepted standard in identifying oligoclonal bands (OCB), but establishing a sensitive immunonephelometric method for quantification of kappa free light chains (KFLC) in cerebrospinal fluid (CSF) has paved a way for new diagnostic possibilities.
