Objective: The purpose of th.s.study was to determine whether genetic variability in oxidative stress- related enzymes contributes to individual preeclampsia susceptibility differences. study Design: Polymorph.s.s in the cytochrome P450 (CYP)1A1 (MspI), CYP1A1(Ile/Val), glutathione stransferase (GsT)M1, GsTT1, myeloperoxidase (MPO), and manganese superoxide dismutase (MnsOD) genes were evaluated by polymerase chain reaction (PCR) or PCR- restriction fragment length polymorph.s. (RFLP) in 214 healthy controls with an uncomplicated obstetric h.s.ory, and in 121 preeclampsia patients. χ 2 analyses were used to statistically evaluate differences. Results: No significant differences in the CYP1A1(MspI) or CYP1A1(Ile/Val) genotypes were observed between the healthy controls and the preeclampsia patients (χ 2 = 1.43, P = 0.49 versus χ 2 = 1.54, P = 0.46). The GsTM1 homozygous null type and GsTT1 homozygous null type were no differences in the patients and controls (χ 2 = 0.01, P = 0.92 versus χ 2 = 0.31, P = 0.57), and no significant differences in the polymorph.s.s of the MPO and MnsOD genotypes were found between the patients and controls (χ 2 = 2.00, P = 0.37 versus χ 2 = 0.07, P = 0.96). Conclusion: Polymorph.s.s in the oxidative stress- related genes (CYP1A1, GsTM1, GsTT1, MPO, MnsOD) do not seem to be risk factors for preeclampsia.

A simplified model was developed to describe the Curie temperature suppression of ferromagnetic nanoparticles. Based on a size and shape dependent model of coh.s.ve energy, the critical temperature variations of ferromagnetic nanoparticles were deduced. It is predicted that the Curie temperature of nanoparticles depends on both.s.ze and shape conditions, among which the temperature suppression is strongly influenced by the particle size and the shape effect is comparably minor. The calculation values for freestanding nanoparticles are in good agreement with other theoretical model and the experimental results. The model is also potential for predictions for the nanoparticles embedded in different substrates.

Laser ablation inductively coupled plasma mass spectrometry （LA-ICP-Ms） h.s.been widely adopted for the direct multi-elemental analysis with high.s.nsitivity. Especially analysis of fine ceramics by LA-ICP-Ms without time-consuming sample decomposition process h.s.been one of the most expecting application field. small additive elements in MgO powders were analyzed by LA-ICP-Ms. For precise and accurate analysis influence of carrier gas （Ar or he） was presented by the signal intensities of ICP-Ms, relative standard deviation of signal intensities and ablated particle size distribution. Ablated particles were collected and analyzed by scanning electron microscopy （sEM） to investigate the particle size distribution, and the ablated sample surface was examined by camscope. In he gas atmosphere, the signal was more stable than in Ar gas atmosphere. The signal intensity was higher in Ar than in he. Examination of ablated particles and sample surface reveals that more particles were generated in Ar atmosphere and the distribution of particle size was larger.

The hydration of quick lime and the sulfation of hydrated lime were carried out for verification of relationship between the reactivity of quick lime and the properties of hydrated lime as a sorbent. The effect of reactivity of quick lime was investigated with the change of calcination temperature and time. Results obtained showed that the temperature rise during the hydration of quick limes varied from 31 to 69℃ with the variation of calcination temperature and time. The specific surface area and the sulfation ability of hydrated lime prepared by hydration of quick lime showed a proportional relationship with the reactivity of quick lime. The hydrated lime which was prepared by hydration of quick lime calcined at 1100℃ had the high.s. reactivity and showed 41.53 m^2/g of the specific surface area, 0.16 cm^3/g of the pore volume and 87% of the removal efficiency for sO2 removal,
