Analysis on the Growth Rhythm and Cold Tolerance of Five-Year Old Eucalyptus benthamii Plantation for Bioenergy  [PDF]
Aihua Yu, Tom Gallagher
Open Journal of Forestry (OJF) , 2015, DOI: 10.4236/ojf.2015.56052
Abstract: A research plot of Eucalyptus benthamii was planted to evaluate this species’ ability to supply the emerging bioenergy markets that are developing in the southern U.S. The plot was planted in two different densities to investigate the growth parameters and the cold tolerance. The stand was measured annually through five growing seasons. The results indicated that the growth difference among the young E. benthamii was noticeable. For example, the maximum and minimum value of five-year old trees at diameter breast height (DBH) was 27.9 centimeters and 1.27 centimeters; and the maximum and minimum value of tree height was 22.86 meters and 2.44 meters, respectively. The yearly change in DBH and height of E. benthamii had significant differences. The average annual survival rates of E. benthamii had differences under the two planting densities (1650 trees ha-1 and 1237 trees ha-1). The densities also had effects on the height and DBH growth of E. benthamii. The average DBH and height of 1650 trees ha-1 plantation were 11.18 centimeters and 15.03 meters, and the average DBH and height of 1237 trees ha-1 plantation were 13.46 centimeters and 16.28 meters. The volume per hectare of 1650 trees ha-1 and 1237 trees ha-1 plantation were 111.45 cubic meters and 101.15 cubic meters, respectively. Average diameter growth was almost 2.54 centimeters per year and average height growth was over 3 meters. E. benthamii plantations were considered tolerant to -7.4 degrees Celsius and a cold spell during early 2014 (-11.3 degrees Celsius for two consecutive nights) killed the plantation. The growth of E. benthamii also
Rho GTPases and Regulation of Cell Migration and Polarization in Human Corneal Epithelial Cells
Aihua Hou, Li Xian Toh, Kah Hui Gan, Khee Jin Ryan Lee, Edward Manser, Louis Tong
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0077107
Abstract: Purpose Epithelial cell migration is required for regeneration of tissues and can be defective in a number of ocular surface diseases. This study aimed to determine the expression pattern of Rho family small G-proteins in human corneal epithelial cells to test their requirement in directional cell migration. Methods Rho family small G-protein expression was assessed by reverse transcription-polymerase chain reaction. Dominant-inhibitory constructs encoding Rho proteins or Rho protein targeting small interfering RNA were transfected into human corneal epithelial large T antigen cells, and wound closure rate were evaluated by scratch wounding assay, and a complementary non-traumatic cell migration assay. Immunofluorescence staining was performed to study cell polarization and to assess Cdc42 downstream effector. Results Cdc42, Chp, Rac1, RhoA, TC10 and TCL were expressed in human corneal epithelial cells. Among them, Cdc42 and TCL were found to significantly affect cell migration in monolayer scratch assays. These results were confirmed through the use of validated siRNAs directed to Cdc42 and TCL. Scramble siRNA transfected cells had high percentage of polarized cells than Cdc42 or TCL siRNA transfected cells at the wound edge. We showed that the Cdc42-specific effector p21-activated kinase 4 localized predominantly to cell-cell junctions in cell monolayers, but failed to translocate to the leading edge in Cdc42 siRNA transfected cells after monolayer wounding. Conclusion Rho proteins expressed in cultured human corneal epithelial cells, and Cdc42, TCL facilitate two-dimensional cell migration in-vitro. Although silencing of Cdc42 and TCL did not noticeably affect the appearance of cell adhesions at the leading edge, the slower migration of these cells indicates both GTP-binding proteins play important roles in promoting cell movement of human corneal epithelial cells.
Evaluation of Global Differential Gene and Protein Expression in Primary Pterygium: S100A8 and S100A9 as Possible Drivers of a Signaling Network

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0097402
Abstract: Purpose Pterygium is a wing shaped fibrovascular growth on the ocular surface, characterized by fibrosis, angiogenesis, extracellular matrix remodeling, and inflammatory infiltrates. Epidemiologic studies have linked pterygium formation to various chronic inflammatory conditions, such as ultraviolet radiation, sawdust exposure, and dry eye disease. The purpose of this study is to identify proteins that are differentially expressed in primary pterygium by using a combination of gene microarray and proteomic platforms. Methods Paired pterygium and uninvolved conjunctiva tissues of four patients were evaluated for differences in global gene transcript levels using a genechip microarray. Proteins extracted from another four pairs of tissues were quantified by iTRAQ approach. Western blot and immunofluorescent staining on additional patients were used to validate dysregulated protein expression obtained from microarray and proteomics data. In addition, primary conjunctival fibroblasts were treated with recombinant S100A8, S100A9 or both. Transcript level changes of a panel of potential target genes were evaluated by real time-PCR. Results The following were up-regulated at both protein and transcript levels S100 A8 and A9, aldehyde dehydrogenase 3 family, member1 (ALDH3A1) and vimentin (VIM). Conversely, serpin peptidase inhibitor clade A member 1 (SERPINA1) and transferrin (TF) were down-regulated. Upon adding S100A8, S100A9 or both, the inflammatory chemokine CXCL1, matrix proteins vimentin, biglycan, and gelsolin, as well as annexin-A2, thymosin-β4, chymase (CMA1), member of Ras oncogene family RAB10 and SERPINA1 were found to be up-regulated. Conclusions We identified 3 up-regulated and 2 down-regulated proteins by using a stringent approach comparing microarray and proteomic data. On stimulating cells with S100A8/9, a repertoire of key genes found to be up-regulated in pterygium tissue, were induced in these cells. S100A8/9 may be an upstream trigger for inflammation and other disease pathways in pterygium.

Their diagnostic error is estimated. And an accurate relation between electron energy spectral indexδ and brightness temperature spectral indexβ is also given.
Micro-Holistic Body Model: Reconciliation of Traditional Chinese Medicine With Modern Biomedicine?
Aihua Xie
Iranian Journal of Medical Hypotheses & Ideas , 2011,
Abstract: Development of molecular biology reveals that multicellular organism could be considered as a cell community. By scrutinizing constitution and activities of a single cell under context of the whole community, I got a micro-holistic body model constituted of two aspects and seven compartments. The two inseparable aspects are the extracellular signalling molecules and the cells that communicate with each other using extracellular signalling molecules. The seven compartments include three universal sub-cellular compartments running within every cell in the body and four specific systems comprised of specific cell groups and molecules providing particular services needed generally by cells in the body. The constitution and internal relationship of the model match the fundamentals of traditional Chinese medicine (TCM) perfectly, thus can philosophically bridge the understanding between traditional Chinese medicine and western medicine, provide research hypotheses, and connect molecular level research with clinical diagnosis and treatment of complex diseases more directly, and may cause profound revolution in human healthcare technology.
An Eco-translatological Perspective to Translator: A Case Study of Xu Chi
Aihua Liu
Theory and Practice in Language Studies , 2011, DOI: 10.4304/tpls.1.1.87-90
Abstract: Xu Chi is a writer and translator. He is known as a poet, essayist and “Father of Reportage” in China. In over sixties years, Xu Chi created a large volume of poems, essays, reportages, etc. and translated many foreign literary works into Chinese. An eco-translatological perspective to literary translator criticism emphasizes translator’s subjectivity with “translator-centeredness”. Xu Chi adapts to the demands of Translational Eco-environment and make selective adaptations and adaptive selections in linguistic, cultural and communicative dimensions. He translates with the pursuit of “doing things with translations” and integrates creation, criticism and translation. A comparatively high degree of selections and adaptations makes his translations well accepted and help to achieve “survival of the fittest”.
Science and Religion from the Perspective of Post-Modernism --- Knowledge System and Religious System
Aihua Xie
Asian Social Science , 2009, DOI: 10.5539/ass.v5n4p10
Abstract: All knowledge belongs to narrative knowledge, and also local knowledge. Post-modernism can be defined as “elimination of grand narrative”, so in the world of post-modernism, validity of knowledge has become an issue. Local knowledge emphasizes that generation and justification of knowledge has its local features, so it has no way to surpass the dilemma of cultural relativism. Theoretically, in this article, the author believes that the standpoint of “moderate relativism” is advisable, which, not only sufficiently respects cultural diversification and particularity of each nation, but emphasizes possibility and necessity of culturally mutual communication of all nations, which attains mutual understanding and recognition during participation and share.
Almost everywhere convergence of ergodic series
Aihua Fan
Mathematics , 2014, DOI: 10.1017/etds.2015.58
Abstract: We consider ergodic series of the form $\sum_{n=0}^\infty a_n f(T^n x)$ where $f$ is an integrable function with zero mean value with respect to a $T$-invariant measure $\mu$. Under certain conditions on the dynamical system $T$, the invariant measure $\mu$ and the function $f$, we prove that the series converges $\mu$-almost everywhere if and only if $\sum_{n=0}^\infty |a_n|^2<\infty$, and that in this case the sum of the convergent series is exponentially integrable and satisfies a Khintchine type inequality. We also prove that the system $\{f\circ T^n\}$ is a Riesz system if and only if the spectral measure of $f$ is absolutely continuous with respect to the Lebesgue measure and the Radon-Nikodym derivative is bounded from above as well as from below by a constant. We check the conditions for Gibbs measures $\mu$ relative to hyperbolic dynamics $T$ and for H\"{o}lder functions $f$. An application is given to the study of differentiability of the Weierstrass type functions $\sum_{n=0}^\infty a_n f(3^n x)$.
