Autophagy and endocytosis in the amnion.

To search for the origin of nutrition in the amnion, we focused attention on both endocytotic and autophagic pathways. Using ultrastructural and biochemical methods, we examined 20 human amnions at term gestation. The uptake of horseradish peroxidase (HRP) was used for the detection of endocytosis.

Landfill leachate treatment by a coagulation-photooxidation process.

This experimental study was conducted to investigate the effect of treatment of landfill leachate by a coagulation-photooxidation process. The effects of different dosages of coagulant and different pH values on the coagulation processes were compared. The effect of different concentrations of sodium oxalate (Na(2)C(2)O(4)) on the treatment process was also studied after the coagulation was performed using FeCl(3).
