To determine if an increase in the endogenous secretion of parathyroid hormone could decrease sodium reabsorption by the proximal tubule, the ionized calcium concentration of blood perfusing the parathyroid gland of eight unilaterally thyroid parathyroidectomized dogs (TPTX) was reduced by infusion of an isotonic sodium citrate plus sodium chloride solution into the blood supply of the parathyr...

Objective: To develop silver nanoparticles stabilized in the hydroalcoholic extract of Mentha Piperita L. for adjuvant treatment depression. Methodology: In synthesis a solution, 25 mL nitrate (1.0 mmol/L) and 75 sodium borohydride (2.0 were used. These two substances mixed at room temperature under magnetic stirring. Another solution used 100 until boiling was reached 5 citrate (1%) added The ...

abstract food preservatives are often added to food as preservation method. mostly one preservative alone cannot preserve a product effectively. so it is required to create a preservation system to overcome limitations derived from each preservative. using proper selection of different preservatives may lead to significant practical benefits. in this investigation, resistant strain of bacillus ...

Alginate hydrogel is a popular biologically inert material that is widely used in 3D bioprinting, especially in extrusion-based printing. However, the printed cells in this hydrogel could not degrade the surrounding alginate gel matrix, causing them to remain in a poorly proliferating and non-differentiating state. Here, we report a novel study of the 3D printing of human corneal epithelial cel...

PURPOSE To evaluate the influence of acute hypervolemia, achieved through the ingestion of a sodium citrate-rich beverage, on cardiovascular strain and thermoregulatory function, during moderate-intensity aerobic exercise in a warm environment. Sodium citrate's ability to increase buffering capacity was also assessed. METHODS Twelve endurance-trained athletes completed two blind randomized tr...

We evaluated the crystallization of calcium oxalate (CaOx) in undiluted urine, collected 3 hours after intake of a test meal by healthy males. In two experiments in vitro, either the total citrate concentration was increased (urine A) or the pH was elevated (urine B). In addition, in three clinical trials, the bioequivalence of orally taken potassium citrate (PC) and potassium-sodium citrate (P...
