Abstract Mesoporous silica nanoparticles (MSNs) can promote the solubility and absorption of pesticides by plants are widely used as a delivery system to improve efficacy pesticide applications. In this study, MSNs with 20 nm particle size were produced. Additionally, water-soluble chitosan (CS) derivative, here called N-(2-Hydroxyl) propyl-3- tri-methyl-ammonium CS chloride (HTCC) was produced...

The influx ofl-lysine into apical vesicles from the chicken jejunum occurs through two systems, one with low Michaelis constant ( K m) and features of system b0,+ and the other with relatively high K m forl-lysine and with properties of system y+. In the present study the effect of a lysine-enriched diet (Lys, containing 68 g l-lysine/kg dietary protein, control animals 48 g/kg) onl-lysine upta...
