Use of gamma-irradiation pretreatment for enhancement of anaerobic digestibility of sewage sludge

YUAN Shoujun, ZHENG Zheng, YU Xin, ZHAO Yongfu, MU Yanyan

Frontiers of Environmental Science & Engineering 2008, Volume 2, Issue 2,   Pages 247-250 doi: 10.1007/s11783-008-0041-9

Abstract: -irradiation pretreatment on anaerobic digestibility of sewage sludge was investigated in this paper.-irradiation pretreatment.-irradiation treatment. Besides, floc size distribution of sewage sludge shifted from 80–100 ?-irradiation treatment at the doses from 0 to 30 kGy, which indicated the disintegration of sewage sludge-irradiation treatment, which resulted in the release of cytoplasm and increase of soluble chemical oxygen

Frontiers of Medicine 2009, Volume 3, Issue 3,   Pages 330-335 doi: 10.1007/s11684-009-0051-4

Abstract: This study aimed to investigate the protective effect of nicotine on dopaminergic neurons and its mechanisms in mice with Parkinson disease (PD) induced by 1-methyl-4-phenyl-1,2,3, 6-tetrahydropyridine (MPTP). C57BL/6J mice were injected with MPTP for 8 days to establish a PD model. Nicotine was given for 10 days in the nicotine therapeutic group. Animals were examined behaviorally with the pole test and traction test. Tyrosine hydroxylase (TH) and γ-aminobutyric acid (GABA) were determined by using the immunocytochemistry (ICC) method. The ultrastructural changes of the caudate nucleus (CN) were observed under electron microscopy. The results showed that pretreatment with nicotine could improve the dyskinesia of PD mice markedly. Simultaneously, TH-positive ( < 0.01) neurons and GABA-positive ( < 0.05) neurons in the nicotine therapeutic group were significantly more than those in the model group. The ultrastructural injury of the nicotine therapeutic group was also ameliorated. Nicotine has protective effects on the γ-aminobutyric acid neurons and dopaminergic neurons in the MPTP-treated mice.
