The adsorption kinetics of methylene blue (MB) on the hazelnut shell with respect to the initial dye concentration, pH, ionic strength, particle size and temperature were investigated. The rate and the transport/kinetic processes of MB adsorption were described by applying the first-order Lagergren, the pseudo-second-order, mass transfer coefficient and the(More)
BACKGROUND AND AIM OF THE STUDY Atrial fibrillation (AF) is the most common arrhythmia in patients with rheumatic mitral stenosis (MS), with an increased risk of mortality and morbidity. Although recent data have suggested that the inflammatory process is associated with non-valvular AF, the relationship between inflammation and AF occurrence in MS patients(More)
Arsenic (As) is generally found as As(III) and As(V) in environmental samples. Toxicity of As(III) is higher than As(V). This paper presents the characteristics of As(III) biosorption from aqueous solution using the green algae (Ulothrix cylindricum) biomass as a function of pH, biomass dosage, contact time, and temperature. Langmuir, Freundlich and(More)
A simple and sensitive method for the speciation, separation and preconcentration of Cr(VI) and Cr(III) in natural water, soil and sediment samples was developed. Cr(VI) has been separated from Cr(III) and preconcentrated as Cr(III)-diphenylcarbazone complex by using Ambersorb 563 resin and determined by spectrophotometric method at 540 nm. Effect of(More)
Immunosuppressive and anti-inflammatory agents have recently become increasingly popular in the treatment of encapsulating peritoneal sclerosis (EPS). The aim of our study was to investigate the effects of sirolimus on EPS in a rat model. We separated 32 non-uremic rats into four groups: 1 control group, 2 ml isotonic saline injected IP daily for 3 weeks; 2(More)
OBJECTIVES We evaluated the relationship between neutrophil to lymphocyte ratio (NLR) and slow coronary flow (SCF). METHODS A total of 180 participants were recruited to the present study. Of all the participants, 82 patients were with SCF and 98 participants were with normal coronary arteries. Basal characteristics were recorded. Coronary flow was(More)
Brugada syndrome is an inherited disease that has an autosomal dominant pattern of transmission, with varying pervasiveness, which develops in anatomically normal hearts and is characterized by STsegment elevation on the right precordial leads (V1–V3), a right bundle branch block morphology, and increased incidence of fatal ventricular tachyarrhythmias [1].(More)
BACKGROUND Psoriasis vulgaris is a chronic inflammatory disease involving 1-3% of the human population worldwide. Many systemic diseases including cardiovascular disturbances have been described in psoriatic patients. The effect of psoriasis on aortic elasticity parameters has not been well-defined previously. The aim of this study was to determine whether(More)
