AIM To explore the relationship between different structures of tocopherol (Toc) and some phenol compounds and their anti-oxidative activities. METHODS Use the ab initio calculation of molecular mechanics and quantum chemistry. RESULTS The anti-oxidation of Toc was related to the ability to release active hydrogen, i.e., related to the O-H electron(More)
AIM To study the effect of catecholamic acid (CBMIDA) on detoxication of NiCl2. METHODS Mice and rats were injected s.c. or i.m. CBMIDA immediately after i.p. NiCl2. Each mouse was injected i.p. CBMIDA after i.v. 63NiCl2 185 kBq, and radioactivities of various tissues were measured with liquid scintillation counter at 24 h. The localization of 63Ni was(More)
Enterotoxigenic Escherichia coli (ETEC) is a type of pathogenic bacteria that cause diarrhea in piglets through colonizing pig small intestine epithelial cells by their surface fimbriae. Different fimbriae type of ETEC including F4, F18, K99 and F41 have been isolated from diarrheal pigs. In this study, we performed a genome-wide association study to map(More)
Sodium dimercaptosuccinate (Na-DMS) ip 1 g.kg-1, dimercaptosuccinic acid (DMSA) ig 1 g.kg-1, DMSA ig 1 g.kg-1 with NaHCO3 or Na-citrate ig 3 g.kg-1 was given to mice, separately. It enhanced the excretion of 210Pb in urine about 3.4, 3.8, 3.6, and 2.3 times vs control, respectively within 24 h. It enhanced the excretion of 203Hg in urine about 2.4, 2.3,(More)
Thorium(IV) biosorption is investigated by citric acid treated mangrove endophytic fungus Fussarium sp. #ZZF51 (CA-ZZF51) from South China Sea. The biosorption process was optimized at pH 4.5, equilibrium time 90 min, initial thorium(IV) concentration 50 mg L(-1) and adsorbent dose 0.6 g L(-1) with 90.87% of removal efficiency and 75.47 mg g(-1) of(More)
Prokaryotic expression technology was used to express maltose-binding protein binding myostatin (MSTN) propeptide fusion protein. Six disease-free Altay lambs were used in this study. The right leg gastrocnemii were injected with MSTN recombinant propeptide protein. The left leg gastrocnemii (the control group) were injected with the same dose of phosphate(More)
This paper reports the venom from Agkistrodon halys Pallas have inhibitory activity against fungi and E. coli by tested in a disc diffusion assay. An antibacterial component--LAO from the venom were purified to homogeneous. It had not only antibacterial effect, but L-amino acid oxidase activity. And its enzymatic specific activity was 808 U/mg. The venom(More)

By indirect immunofluorescence assay, the authors examined the lymphocyte subsets in peripheral blood of patients with HSK and normal individuals, using monoclonal antibodies. The relation between the alterations of T-lymphocyte subsets and the mechanism of HSK relapse was discussed. It is postulated that the alterations of T-lymphocyte subsets may help(More)
There is a dearth of data about the prevalence of hepatitis B virus (HBV) infection in Mengla, China; and no detailed analysis of the molecular evolution of genotype I in Asia. In this study, 909 serum samples from ethnic minority people in China were obtained. Serological assay and HBV S-gene amplification were carried out, and phylogenetic and(More)
