Abstract The aim of the research was to evaluate effect three types silver nanoparticles (AgNPs) with different physicochemical properties and ions delivered in form nitrate (AgNO 3 ) at concentration 50 mg L −1 on germination initial growth monocots (common wheat, sorghum) dicots (garden cress, white mustard). AgNPs were prepared using trisodium citrate (TCSB-AgNPs), tannic acid (TA-AgNPs), cy...

Heat-stable endopeptidases in raw milk, especially the alkaline metallopeptidase AprX secreted by Pseudomonas spp., are a well-known challenge for dairy industry. They can withstand UHT treatment and may cause quality defects over shelf life of milk products. Therefore, we established an indirect ELISA detection milk. We developed 2-step sample contaminated with to avoid interference proteins s...

BACKGROUND The incidence of acute kidney injury (AKI) is estimated at 10 to 20% in patients admitted to intensive care units (ICU) and often requires renal replacement therapy (RRT). ICU mortality in AKI patients can exceed 50%. Venous catheters are the preferred vascular access method for AKI patients requiring RRT, but carry a risk of catheter thrombosis or infection. Catheter lock solutions ...

BACKGROUND The standard method of assessment of platelet function is represented by light transmission aggregometry (LTA), performed in citrated platelet-rich plasma (PRP). With LTA, decrease and subsequent post-cardiopulmonary bypass (CPB) recovery of platelet function have been reported during cardiac surgery. Multiple electrode aggregometry (MEA) may be used as point-of-care method to monito...

objective(s): this paper describes coating of magnetite nanoparticles (mnps) with amorphous silica shells.   materials and methods: first, magnetite (fe3o4) nps were synthesized by co-precipitation method and then treated with stabilizer molecule of trisodium citrate to enhance their dispersibility. afterwards, coating with silica was carried out via a sol-gel approach in which the electrostati...

Single crystals of tris-odium scandium bis-(orthoborate), Na(3)Sc(BO(3))(2), have been obtained by spontaneous crystallization from an Na(2)O-Sc(2)O(3)-B(2)O(3) melt. The crystal structure features a three-dimensional framework composed of planar [BO(3)](3-) groups and distorted ScO(6) octa-hedra with Na atoms in the cavities. The Sc atom occupies a special position (Wyckoff position 2b, site s...

INTRODUCTION Neutrophil gelatinase-associated lipocalin (NGAL) is a biomarker of acute kidney injury (AKI), and levels reflect severity of disease in critically ill patients. However, continuous venovenous hemofiltration (CVVH) may affect plasma levels by clearance or release of NGAL by activated neutrophils in the filter, dependent on the anticoagulation regimen applied. We therefore studied h...

BACKGROUND Pharmacokinetic studies are vital in development and optimization of drugs. While blood samples can be collected either in EDTA, heparin or citrate containing tubes for the estimation of drug levels in plasma, EDTA tubes are more commonly used. The purpose of this study was to evaluate the effects of anticoagulants on bioanalysis of drugs. Six drugs used extensively in cancer therapy...
