Abstract Background Patients with rheumatoid arthritis (RA) have a higher cardiovascular risk (CVR) compared to the general population contributing decreased life expectancy. Systematic and periodic assessment of CVR is recommended in all patients RA. The newly developed PREVENTTM calculator was designed estimate absolute disease provides an atherosclerotic heart failure. Purpose This study aimed evaluate sensitivity specificity new algorithm identify CP RA without prior CVD compare these...
Abstract Background Liver tests are used to evaluate liver damage due medication and have gained attention for their potential role in assessing cardiovascular risk (CVR) patients with rheumatoid arthritis (RA) psoriatic (PsA). In the general population, studies suggest that serum gamma-glutamyl transpeptidase (GGT) levels correlate endothelial dysfunction left ventricular (LV) alterations, leading a higher of events. contrast, bilirubin (SB), byproduct heme metabolism known its antioxidant...
Abstract Background Rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and psoriatic (PsA) are heterogeneous autoimmune diseases with established cardiovascular involvement associated a higher risk of developing heart failure (HF). Studies have shown greater for HF in rheumatologic patients compared to the general population, however, calculated varies among studies. PREVENTTM is first calculator predict HF. Purpose To evaluate performance novel detect subclinical inflammatory...
Abstract Background Platelet/lymphocyte ratio (PLR) has recently been described as a predictor for adverse cardiovascular outcomes, such heart failure and coronary artery disease. In systemic lupus erythematosus (SLE), PLR studied marker of disease activity. not evaluated biomarker in SLE. Purpose To compare the prevalence echocardiographic abnormalities between normal high patients with Methods Cross-sectional, retrospective, descriptive study. Women older than 18 years who met ACR/EULAR...
In this paper we report on the influence of polysaccharides’ molecular structure antibacterial activity and cytotoxicity composites based silver nanoparticles (AgNPs) immobilized into carboxymethyl-cellulose (CMC). These were green synthesized from reduction ions aqueous solutions polysaccharide, using CMC with different degree substitution (DS) weight (Mw). The characterized by transmission electron microscopy (TEM), as well infrared (ATR-FTIR), ultraviolet (UV-Vis), Raman, X-ray...
In this contribution, a totally ecofriendly synthesis of silver nanoparticles from aqueous dissolution polysaccharides is reported. The was performed using dissolutions nitrate (AgNO 3 ) and carboxymethyl-cellulose (CMC) as both reducing stabilization agent different AgNO : CMC weight ratios. Resultant yellowish to reddish dispersions were characterized by means transmission electron microscopy their related techniques, such bright field Z-contrast imaging diffraction, well...
Abstract A magnetic hybrid material (MHM), consisting of iron‐oxide nanoparticles (˜4 nm) embedded in sodium carboxymethyl cellulose (Na‐CMC) matrix was synthesized. The MHM synthesis process performed two stages. First, a precursor (Fe(II)‐CMC) synthesized from aqueous solutions: Na‐CMC solution and FeCl 2 solution. In the second stage, treated with H O under alkaline conditions to obtain MHM. results obtained X‐ray diffraction show that crystalline structure iron oxide into corresponds...
In this work, the desorption of furfural, which is a competitive intermediate during production biofuel and valuable aromatic compounds, was studied using pure alumina, as well alumina impregnated with iron platinum oxides both individually in combination, thermogravimetric analysis (TGA). The bimetallic sample exhibited lowest percentage for furfural. High-resolution transmission electron microscopy (HRTEM) imaging revealed intimate connection between oxide species on support. mechanism...
(Cholesteryl)benzoateethynylene oligomers having 3, 5 and 7 repeat units the homologue polymer were synthesized by a divergence–convergence approach Sonogashira–Heck reaction. Their chemical structure was analyzed 1H, 13C NMR, UV-Vis, fluorescence spectroscopy circular dichroism. X-Ray diffraction patterns of all materials show only first order peak at 2.05° in 2θ, indicative lamellar within distance 4.3 nm. This is twice calculated molecule its more extended conformation, i.e. 2.15 nm,...
Abstract Sodium nanoclay was modified by plasma polymerization using ethylene gas. Due to the complexity of its lamellar morphology that prevents from entering into clay galleries, a new two‐step strategy employed. This method proved be effective in overcoming limited accessibility first exposing under pressure 0.14 MPa (1.4 kg · cm −2 ), followed while within galleries. Fourier transform infrared (FTIR)spectroscopy, dispersion tests water, Raman spectroscopy, X‐ray photoelectronic...
