INTRODUCTION Total dialysate calcium concentration has an important influence on calcium metabolism in bicarbonate high-flux dialysis. The aim of the study is to investigate the influence of different dialysate calcium concentrations on serum concentration of ionised calcium and on the balance of total dialysate calcium. MATERIALS AND METHODS A total of 20 stable aneuric patients on chronic b...

 Background: Hypocalcemia is a well-recognized complication after total thyroidectomy. Hypovitaminosis D may have additional effect in the development of hypocalcemia. This study aimed to determine the effect of total thyroidectomy on postoperative serum calcium in patients with and without hypovitaminosis D. Methods: This prospective study was performed on patients who underwent total...

Ketosis is an important metabolic disease of high milk-producing cows. There are significant changes in many metabolite and hormonal concentrations in metabolic diseases. This study was carried out to assess the concentrations calcium (Ca), selenium (Se), total antioxidant (TAOC), insulin, free triiodothyronine (fT3) and free thyroxine (fT4) in cows with subclinical and clinical ketosis. This s...

In this study, linear alkyl-benzene calcium sulfonate nanoparticles were made using linear alkylbenzene. Calcium sulfonate nanoparticles are widely used as an additive in a variety of engine oils and have cleansing, anti-wear and anti-oxidant properties and anti-corrosion properties. In this method, a sulfonation set up was constructed and sulfonation reaction was carried out both directly and ...
