Fibroblast growth factor (FGF) signaling begins with the formation of a ternary complex of FGF, FGF receptor (FGFR), and heparan sulfate (HS). Multiple models have been proposed for the ternary complex. However, major discrepancies exist among those models, and none of these models have evaluated the functional importance of the interacting regions on the HS chains. To resolve the discrepancies...

BACKGROUND Systemic low-grade inflammation (SLGI), as assessed by measurements of high-sensitivity C-reactive protein (hs-CRP), is a strong independent risk factor for cardiovascular diseases (CVD). Although individuals with hs-CRP ≤ 1 mg/L have been defined as being at low risk according to AHA/CDC guidelines, the value of very low hs-CRP levels (<0.5 mg/L) for public health practices is uncle...

AIMS This study investigated the possible association between hs-CRP as well as hs-CRP changes and rhythm outcome after AF catheter ablation. METHODS We studied 68 consecutive patients with AF undergoing catheter ablation. hs-CRP levels were measured using commercially available assays before and 6 months after catheter ablation. Serial 7-day Holter ECGs were used to detect AF recurrences. ...

INTRODUCTION Antibodies directed against neuronal surface antigens have recently been identified in patients with focal temporal lobe epilepsy (TLE) of unknown cause and mesial TLE with hippocampal sclerosis (MTLE-HS), thereby emphasizing the role of autoimmunity in TLE. Antibodies to contactin-associated protein-like 2 (CASPR2) are prevalent in MTLE-HS patients. We aimed to find out whether an...

Heparan sulfate (HS) is an important component of the extracellular matrix and cell surface, which plays a key role in cell-cell and cell-matrix interactions. Functional activity of HS directly depends on its structure, which determined by a complex system of HS biosynthetic enzymes. During malignant transformation, the system can undergo significant changes, but for glioma, HS biosynthesis has...

BACKGROUND While hypertension is negatively associated with coronary artery spasm (CAS), scarce data are available on diabetes mellitus in relation to CAS. In addition, outcome prediction in patients with CAS is challenging due to the lack of appropriate biomarkers. Therefore, we sought to identify the roles that gender, high-sensitivity C-reactive protein (hs-CRP), diabetes mellitus and hypert...

BACKGROUND The exacerbation of IgA nephropathy (IgAN) is related to respiratory tract infection with hemolytic streptococcus (HS), but the mechanism is unknown. In this study we investigated the role of chemokine ligand 20 (CCL20) in response to the effect of T helper 17 (Th17) cells in the pathogenesis of IgAN associated with HS. METHODS Thirty mice were randomly divided into five groups: co...

A body mass index (BMI)>or=25 kg/m2 increases the risk for long-term renal damage, possibly by renal hemodynamic factors. As epidemiological studies suggest interaction of BMI and sodium intake, we studied the combined effects of sodium intake and BMI on renal hemodynamics. Glomerular filtration rate (GFR) and effective renal plasma flow (ERPF) were measured in 95 healthy men (median age 23 yea...

INTRODUCTION Hemophagocytic syndrome (HS) occurs in autoimmune diseases and belongs to the hemophagocytic lymphohistiocytosis group of diseases. This paper describes the features of 2 patients with systemic lupus erythematosus (SLE) who presented HS as the initial clinical manifestation. CLINICAL OBSERVATIONS Both patients had prolonged fever not associated to an infectious process and did no...
