A new bioflocculant was produced by culturing Rhodococcus erythropolis in a cheap medium. When culture pH was 7.0, inoculum size was 2 % (v/v), Na2HPO4 concentration was 0.5 g L−1, and the ratio of sludge/livestock wastewater was 7:1 (v/v), a maximum flocculating rate of 87.6 % could be achieved. Among 13 different kinds of pretreatments for sludge, the(More)
BACKGROUND Polysaccharides from various sources are being considered potential sources for the treatment of liver cancer. The aim of this study was to investigate the impact of polysaccharide isolated from Panax notoginseng (PPN) on the proliferation of H22 liver cancer cells and the survival of the tumor-bearing mice transplanted with H22 cells.

PURPOSE We assessed the relationship between axial length (AL) change and corneal refractive power change induced by orthokeratology (ortho-k) contact lens wear. METHODS A total of 88 myopic children aged 7 to 12 years were fitted with ortho-k lenses for overnight wear. Axial length was measured before enrollment and every 6 months after initiation of(More)
