The investigation of surface tension is a very important task for gas hydrate studying. Surfactants can effectively reduce the surface tension, improve the gas storage capability of hydrate and increase the formation rate, shorten the induction time. The objective of this study were to obtain a better understanding of the role of surface tension on hydrate formation and build gas hydrate models involve surfactant. In this study it was highlighted that the surface tension of Intechem-01 + SDS composite surfactants in natural gas hydrate promotion system and the change rules at different temperatures, concentration and proportion. According to the results of experiment, the surface tension of composite surfactants decreased with the increase of Intechem-01. The best cooperating effect was observed in proportion (Intechem-01 content) of 0.6 - 0.7, where the surface tension was the lowest. In this proportion range, the composite surfactants showed the same effect to pure fluorine carbon surfactant. The study shown the surface tension of composite surfactants decreased with the rise of temperature, and they were in a linear relationship within a certain range. Surface tension of composite surfactants decreased with the increase of surfactant concentration, however, it was no longer decreased above critical micelle concentration (CMC). The fitting equation of surface tension with various factors has been obtained.

Natural gas hydrate has tremendous gas storage capacity; natural gas hydrate can be used to store and transport energy. The current problem faced is how to improve the hydrate formation rate and storage capacity, and form continuously. Compared to the pure water and SDBS solution, the ionic solution [HMIPS]OTs made by the team was the excellent additive and ensured the best reaction concentration range. Specific effects of different additives on hydrate formation were summarized; hydrate formation mechanism of additives was expounded. Considering the investment cost, operation cost, simple and stable operation of different surfactants, it is thought that the study of different additives mechanisms and developing the new efficient additive have the important value.

Chinese Journal of Lung Cancer , 2009,
Abstract: Background and objective To explore the correlation between p120-catenin (p120ctn) and small GTPases in human lung cancer, and their effect on the cell-cell adhesion, we examined the expression patterns of p120ctn and Rac1, which is the core member of small GTPases, and their correlation with clinicopathological factors. Methods S-P immunohistochemistry, Western Blot, and RT-PCR were used to detect the expression patterns of p120ctn and Rac1 in 138 patients with non-small cell lung cancer (NSCLC) and two kinds of homologous lung cancer cell lines. We also used an in vitro model to evaluate their expression, and to determine whether protein expression correlated with the invasive capacity of lung cancer cell lines. Results In lung cancer, the levels of protein and mRNA expression of p120ctn were significantly lower than normal lung tissue, and Rac1 was also found to be higher in tumor tissue than in normal lung tissue. A correlation between abnormal p120ctn and overexpression of Rac1 (Correlation coefficient=0.720, P <0.001)was also associated with malignancy of lung cancer, such as poor differentiation (P =0.022), high TNM stage (P =0.010), and lymph node metastasis (P =0.009) in NSCLC patients. Abnormal expression of p120ctn and overexpression of Rac1 was significantly associated with the high metastatic capacity of BE1 cells. Conclusion Abnormal p120ctn expression correlates with Rac1 overexpression, which contributes to the malignancy-related of NSCLC.

Chinese Science Bulletin , 2001, DOI: 10.1007/BF03187176
Abstract: A mRNA preferentially expressed in cotton fiber was cloned from fiber total RNA of normal upland cotton TM-1 (wild-type) by using RT-PCR and corresponding cDNA (signed asTM-E6) was sequenced.TM-E6 gene had no intron and contained an open reading frame of 771 bp long, and might encode a peptide of 246 amino acids. Other 4 genes,Fl-E6, Li-E6, N-E6 andBl-E6, which were homologous toTM-E6 gene, were also isolated from 4 fiber mutants of Fiberless Xu-zhou 142, Ligon lintless, Naked seed and Brown lint, respectively. Sequence analysis of each of these mutant genes revealed many variations in structure and nucleotide composition of gene when compared with the sequence ofTM-E6 gene. (i) There was a changeable repetitive segment in which GGCTCA (Gly-Ser) was repeated 3–5 times between the 82nd and the 93rd codons in different mutant genes. Since the change of Gly-Ser repetitive segment occurred not only in the mutants but also in the wild-type cotton, the repeat frequency might not be associated with the mutation of fiber characteristics, (ii) Among the 4 mutant genes, the percentage of changed codons was 7.05% inFl-E6, 4.98% inLi-E6, and 4.15% inN-E6 andBl-E6. It seems that the percentage of changed codons inE6 sequence was positively correlated to the degree of fiber morphological variation, (iii) E6 polypeptides of two long-fiberless mutants (Fiberless Xuzhou 142 and Ligon lintless) contained high similar (99.4%) variation in the region of 1–174 amino acids from N-terminus, and those of short-fiberless mutants (Fiberless Xuzhou and naked seed) revealed identical variation in the region of 116th–220th amino acids. It also seems that there was a parallel relation between E6 protein variation and fiber phenotype mutation, (iv)Li-E6 andBl-E6 genes also expressed at low level in seed coat besides at high level in fiber.

Abstract: Background The methylotrophic yeast Pichia pastoris is widely used as a bioengineering platform for producing industrial and biopharmaceutical proteins, studying protein expression and secretion mechanisms, and analyzing metabolite synthesis and peroxisome biogenesis. With the development of DNA microarray and mRNA sequence technology, the P. pastoris transcriptome has become a research hotspot due to its powerful capability to identify the transcript structures and gain insights into the transcriptional regulation model of cells under protein production conditions. The study of the P. pastoris transcriptome helps to annotate the P. pastoris transcript structures and provide useful information for further improvement of the production of recombinant proteins. Results We used a massively parallel mRNA sequencing platform (RNA-Seq), based on next-generation sequencing technology, to map and quantify the dynamic transcriptome of P. pastoris at the genome scale under growth conditions with glycerol and methanol as substrates. The results describe the transcription landscape at the whole-genome level and provide annotated transcript structures, including untranslated regions (UTRs), alternative splicing (AS) events, novel transcripts, new exons, alternative upstream initiation codons (uATGs), and upstream open reading frames (uORFs). Internal ribosome entry sites (IRESes) were first identified within the UTRs of genes from P. pastoris, encoding kinases and the proteins involved in the control of growth. We also provide a transcriptional regulation model for P. pastoris grown on different carbon sources. Conclusions We suggest that the IRES-dependent translation initiation mechanism also exists in P. pastoris. Retained introns (RIs) are determined as the main AS event and are produced predominantly by an intron definition (ID) mechanism. Our results describe the metabolic characteristics of P. pastoris with heterologous protein production under methanol induction and provide rich information for further in-depth studies of P. pastoris protein expression and secretion mechanisms.

Modern Applied Science , 2010, DOI: 10.5539/mas.v4n6p60
Abstract: The article made an empirical econometric analysis on the fluctuation of China’s total Energy Consumption and then estimated GARCH model, TARCH model and EGARCH model by the way of maximum-likehood estimation. Empirical studies showed GARCH model made the best estimation in statistics and the fluctuation rate was altering. And the fluctuation’s impact on China’s energy consumption was very high. The TGARCH and EGARCH models also showed that it had asymmetrical relation with the fluctuation of China’s total energy consumption. The authors summarized the features of volatility from empirical results and put forward some suggestions for further development and improvement.

Abstract: N-doped Titanium dioxide (TiO2) nanotube arrays were formed by electrochemical anodization, and then impregnated in 1 mol/L ammonia for 24 h before annealed at 450℃ to synthesize N doped TiO2 arrays. The samples were characterized by scanning electron microscope (SEM), X-ray Diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) to analyse its surface morphology, crystal types and the doping behavior of nitrogen. The material was used as electrode for photoelectrocatalytic degradation of hexachlorobenzen (HCB) under irradiation of simulated sunlight. The results showed that the degradation effect reached the optimality whose rate was 95% when bias potential was 1V, the concentration of Na2SO4 was 0.2 mol/L, and pH was 5.0.
Age effect of deafening on stereotyped song maintenance in adult male bengalese finches Lonchura striata domestica

Current Zoology , 2009,
Abstract: Birdsong is a complex learned vocal behavior that relies on auditory experience for development. However, it appears that among different species of close-ended songbirds, there are some variations in the necessity of auditory feedback for maintaining stereotyped adult song. In zebra finches, the deterioration of adult songs following deafness depends on the birds’ age. It is unknown whether this age effect is a general rule in other avian species as well. Therefore, we chose Bengalese finches, whose songs show more complexity and have much heavier dependency on auditory feedback than that of zebra finches, to compare the degree of song degradation after hearing loss in old (over 18 months old) and young adult birds (5–6 months old). We found that both syllable sequence and syllable phonology were much less severely affected by deafening in old adults than that in young ones. Moreover, young adults almost lost their capability to sing trills over 6 months following deafening, while old birds continued to sing plenty of trills and trilled syllables after the same period of deafening. Our results suggest that age plays an important role in affecting the dependency of adult song maintenance on auditory feedback in Bengalese finches. Furthermore, the age dependency may be a general phenomenon in different species of close-ended songbirds [Current Zoology 55(3):212–218, 2009].
