Genome-Wide Comparative in silico Analysis of Calcium Transporters of Rice and Sorghum

The mechanism of calcium uptake, translocation and accumulation in Poaceae has not yet been fully understood. To address this issue, we conducted genome-wide comparative in silico analysis of the calcium (Ca~(2+)) transporter gene family of two crop species, rice and sorghum. Gene annotation, identification of upstream cis-acting elements, phylogenetic tree construction and syntenic mapping of the gene family were performed using several bioinformatics tools. A total of 31 Ca~(2+) transporters, distributed on 9 out of 12 chromosomes, were predicted from rice genome, while 28 Ca~(2+) transporters predicted from sorghum are distributed on all the chromosomes except chromosome 10 (Chr 10). Interestingly, most of the genes on Chr 1 and Chr 3 show an inverse syntenic relationship between rice and sorghum. Multiple sequence alignment and motif analysis of these transporter proteins revealed high conservation between the two species. Phylogenetic tree could very well identify the subclasses of channels, ATPases and exchangers among the gene family. The in silico cis-regulatory element analysis suggested diverse functions associated with light, stress and hormone responsiveness as well as endosperm- and meris-tem-specific gene expression. Further experiments are warranted to validate the in silico analysis of the predicted transporter gene family and elucidate the functions of Ca~(2+) transporters in various biological processes.
The Effect of Glycyl-Glutamine Dipeptide Concentration on Enzyme Activity, Cell Proliferation and Apoptosis of Jejunal Tissues from Weaned Piglets

An experiment was conducted in a singly factorial design to study the effect of glycyl-glutamine dipeptide on enzyme activity, cell proliferation and apoptosis of jejunal tissues from weaned piglets at different glycyl-glutamine concentration levels of 2, 4, 10, 20, and 30 mmol L~(-1), respectively. The glutaminase activity, diamine oxidase (DAO) activity, cell peoliferation, apoptosis, and perotein metabolism were measured by the tissue culture method in vitro using jejunal tissues. The immunohistochemical method was used to study the cell proliferation and apoptosis of jejunal tissues. The results showed that compared to the blank control, the percentage and MOD value of BrdU-positicve cells incubated with glycyl-glutamine dipeptide solution were significantly (P<0.05) increased. Accordingly, the percentage and MOD value of caspase-3-positive cells from tissue incubated with glycyl-glutamine dipeptide were notably lower (P<0.05) than that from the control treatment. The glycyl-glutamine dipeptide increased the glutaminase activity, DAO activity and protein content of jejunal tissues, as the dipeptide concentration was on the rise (P<0.05). These results indicated that glycyl-glutamine dipeptide affected the jejunum development and adaptation of weaned piglets, and the function might be fulfilled by enhancing the glutamine-related enzyme activity, thereby increasing the consumption of glutamine, and then improving the jejunal cell proliferation and suppressing cell apoptosis. The effects of glycyl-glutamine dipeptide relied in a dose-dependent manner, and the maximum effect was achieved at 20-30 mmol L~(-1) glycyl-glutamine dipeptide.
Relationship Among Yield Components and Selection Criteria for Yield Improvement in Early Rapeseed (Brassica napus L.)

The objective of this study was to determine the relationship between seed yield and other important agronomic traits of early-maturing rapeseed as a rotation crop in a double-cropping rice area using Pearson’s correlation coefficient as well as to estimate direct and indirect effects of specific yield component traits on seed yield via path analysis. Nineteen rapeseed genotypes were grown at ten environments in South China during 2008-2009 and 12 characters were evaluated. Analysis of variance showed that environment had a significant impact on all characters. For most characters the genotype by environment interaction was weak and not statistically significant. Simple correlation analysis indicated that the number of primary branches (PB), number of pods on the main raceme (PR), and number of seeds per pod made significant contributions to seed yield per plant (SYP), while 1 000-seed weight was negatively correlated with SYP (r=-0.485, P<0.05). Furthermore, number of pods per plant (PP), PB, and PR had the greatest direct effects on SYP. In addition, PP and PB were the best indicators to predict seed yield in stepwise regression analysis. Finally, yield component differences between early- and medium-maturity varieties were compared; this showed that to improve the seed yield of early varieties, more emphasis should be given to increase PP, PB, and PR, and reduce plant height and shortening of growth duration in breeding practice.
Analysis of Heavy Metal Sources for Vegetable Soils from Shandong Province, China

Heavy metal pollution in agricultural soils has serious negative influence on human health. Concentrations of Cd, Hg, As, Pb, Cr, Cu, Zn, and Ni in top soils (0-20 cm) of greenhouses and farmlands from four main vegetable production areas Shouguang, Laiyang, Jinxiang, and Zhangqiu in Shandong Province, one of the most rapidly developing regions in China, were measured in this study. Shouguang is mainly occupied by greenhouse vegetables and the other three areas are mainly open field culture. Total of 149 soil samples were collected. The average concentrations of the eight heavy metals of the tested 149 soil samples were all below the threshold values according to "Farmland environmental quality evaluation standards for edible agricultural products (HJ332-2006)"of China. However, most of the studied heavy metals were present at higher concentrations than those of the natural background levels in local agricultural soils. Among the total 149 soil samples, 22 samples were contaminated by Cd, Ni, Cu, or Hg. Comparisons showed that the main pollution element in greenhouse vegetable soils was Cd, while that of open field vegetable soils was Cu. The results of principal components analysis (PCA) suggested that concentrations of Cr, As, and Ni were mainly controlled by parent rocks; Hg and Pb were affected by anthropogenic activities such as vehicle and industrial fumes and waste water irrigation. Meanwhile, concentrations of Cd, Cu, and Zn were affected mainly by the use of agrochemicals. Most of the heavy metals were positively correlated with each other in concentration. Appropriate measures should be taken to effectively control heavy metal levels in vegetable soils and thus protect human health.
Rapid HPLC Method for Determination of 12 Isoflavone Components in Soybean Seeds

It is important to determine the isoflavone components by high-performance liquid chromatography (HPLC) for the molecular assistant selection of isoflavone in soybean. Based on the standard samples of 12 isoflavone components, the isoflavone components were analyzed using the determination of absorbance peaks method by HPLC. The results showed that there were different maximum ultraviolet (UV) absorbance for the aglycones of daidzein, glycitein, and genistein, which were at 250, 257, and 260 nm, respectively. A linear gradient elution of acetonitrile (13-30%) containing 0.1% acetic acid as a mobile phase was applied on a YMC-C18 column at 35℃. The 12 isoflavone components were determined using the UV detector by HPLC. We concluded that this is a rapid and precise method which adapted to determine the large numbers of samples with microanalysis.

The influence of pore structure on P-& S-wave velocities in complex carbonate reservoirs with secondary storage space

Secondary storage spaces with very complex geometries are well developed in Ordovician carbonate reservoirs in the Tarim Basin, which is taken as a study case in this paper.It is still not clear how the secondary storage space shape influences the P-& S-wave velocities (or elastic properties) in complex carbonate reservoirs.In this paper, three classical rock physics models (Wyllie timeaverage equation, Gassmann equation and the Kuster-Toks z model) are comparably analyzed for their construction principles and actual velocity prediction results, aiming at determining the most favourable rock physics model to consider the influence of secondary storage space shape.Then relationships between the P-& S-wave velocities in carbonate reservoirs and geometric shapes of secondary storage spaces are discussed from different aspects based on actual well data by employing the favourable rock physics model.To explain the influence of secondary storage space shape on V P-V S relationship, it is analyzed for the differences of S-wave velocities between derived from common empirical relationships (including Castagna’s mud rock line and Greenberg-Castagna V P-V S relationship) and predicted by the rock physics model.We advocate that V P-V S relationship for complex carbonate reservoirs should be built for different storage space types.For the carbonate reservoirs in the Tarim Basin, the V P-V S relationships for fractured, fractured-cavernous, and fractured-hole-vuggy reservoirs are respectively built on the basis of velocity prediction and secondary storage space type determination.Through the discussion above, it is expected that the velocity prediction and the V P-V S relationships for complex carbonate reservoirs should fully consider the influence of secondary storage space shape, thus providing more reasonable constraints for prestack inversion, further building a foundation for realizing carbonate reservoir prediction and fluid prediction.
Surfactant induced reservoir wettability alteration:Recent theoretical and experimental advances in enhanced oil recovery

Reservoir wettability plays an important role in various oil recovery processes.The origin and evolution of reservoir wettability were critically reviewed to better understand the complexity of wettability due to interactions in crude oil-brine-rock system, with introduction of different wetting states and their influence on fluid distribution in pore spaces.The effect of wettability on oil recovery of waterflooding was then summarized from past and recent research to emphasize the importance of wettability in oil displacement by brine.The mechanism of wettability alteration by different surfactants in both carbonate and sandstone reservoirs was analyzed, concerning their distinct surface chemistry, and different interaction patterns of surfactants with components on rock surface.Other concerns such as the combined effect of wettability alteration and interfacial tension (IFT) reduction on the imbibition process was also taken into account.Generally, surfactant induced wettability alteration for enhanced oil recovery is still in the stage of laboratory investigation.The successful application of this technique relies on a comprehensive survey of target reservoir conditions, and could be expected especially in low permeability fractured reservoirs and forced imbibition process.
Delta asymmetry:Concepts, characteristics, and depositional models

Delta asymmetry forms in wave-influenced settings where there is strong net longshore drift.Asymmetric deltas typically have two sediment sources and are characterized by morphology and facies asymmetry between the downdrift and the updrift sides.The downdrift, sourced primarily by the feeding river, are commonly influenced by mixed river and wave processes.Deposits on this side are muddy and consist of barrier, bar, lagoon, bay-fill, and bayhead delta facies with variable bioturbation intensity.At or near the river mouth, heterolithic river-dominated successions are more typical.Deposits are overall unburrowed (BI 0-2), but with high burrowing spikes.Ichnogenera are characterized by horizontal, morphologically simple, and facies-crossing structures.The updrift, in contrast, is sourced by a second sediment source and typically consists of laterally continuous sandy beach and shoreface facies.Bioturbation is overall high (BI 3-6) and ichnogenera are healthy and robust, attributable to the Cruziana and Skolithos Ichnofacies.Depending on shoreline trajectory and depositional history, facies characteristics of asymmetric deltas preserved in the ancient record, however, can be different from those predicted by the models.Degree of asymmetry is indicated by the asymmetry index (A), defined as the ratio between the rate of longshore transport at the river mouth and river water discharge.The indexes in symmetric waveinfluenced deltas is less than 200, whereas those in asymmetric and deflected deltas are larger than 200.Overall the larger the index, the higher the degree of asymmetry.Delta asymmetry concepts and models challenge the traditional definition of deltas and the delta classification scheme.In a hydrocarbon exploration perspective, asymmetric deltas bear very different types of sands and, thus, reservoirs between the updrift and the downdrift.The updrift consists of wellsorted, mature, and laterally continuous homogeneous beach-shoreface reservoirs.The downdrift, in contrast, is muddier and consists of less continuous, less mature, heterolithic reservoirs.
Synthesis, characterization and catalytic properties of Y-β zeolite composites

Y-β zeolite composites were hydrothermally synthesized by using high silica Y zeolite as the precursor and characterized by XRD, N2 adsorption, SEM and IR spectra of pyridine.The result showed that the N2 adsorption-desorption isotherm of the zeolite composites had a distinct hysteresis loop, and the SEM result showed that the zeolite composites had a different morphology from Y, β and the corresponding physical zeolite mixture.The acid catalytic performance of the zeolite composite catalysts was investigated in the hydrocracking and hydroisomerization of n-octane, and the results showed that the composite materials exhibited an excellent hydrocracking activity and good hydroisomerization performance.The yield of i-C4 over the zeolite composite catalyst was 4.45% higher than that on the corresponding zeolite mixture in the n-octane hydrocracking process at 553 K.The isomerization ability of n-octane over the composite catalyst was 3.6 fold that of the corresponding mixture at 503 K.
The effective pressure law for permeability of clay-rich sandstones

To study the relative sensitivity of permeability to pore pressure P_p and confining pressure P_c for clay-rich rocks, permeability measurements were performed on samples of four clay-rich sandstones.A new method(hereafter denoted the "slide method") was developed and used for analyzing the permeability data obtained.The effective pressure coefficients for permeability n_k were calculated.The values of n_k were found to be greater than 1.0 and insensitive to changes in pressure.These results confirmed observations previously made on clay-rich rocks.Also, the coefficients n_k obtained had different characteristics for different samples because of differences in the types of clay they contained.The effective pressure law(σ_(eff)=P_c-n_kP_p) determined using the slide method gave better results about k(σ_(eff)) than classic Terzaghi’s law(σ_(eff)=P_c-P_p).
Experimental study of gas-water elongated bubble flow during production logging

In order to improve the interpretation of production log data on gas-water elongated bubble(EB) flow in horizontal wells, a multi-phase flow simulation device was set up to conduct a series of measurement experiments using air and tap water as test media, which were measured using a real production logging tool(PLT) string at different deviations and in different mixed flow state s.By understanding the characteristics and mechanisms of gas-water EB flow in transparent experimental boreholes during production logging, combined with an analysis of the production log response characteristics and experimental production logging flow pattern maps, a method for flow pattern identification relying on log responses and a drift-flux model wer e proposed for gas-water EB flow.This mo del, built upon experimental data of EB flow, reveals physical mechanisms of gas-water EB flow during measurement processing.Th e coefficients it contains are the specific values under experimental conditions and with the PLT string used in our experiments.These coefficients also reveal the interference with original downhole flow patterns by the PLT string.Due to the representativeness that our simulated flow experiments and PLT string possess, the model coefficients can be applied as e mpirical values of logging interpretation model parameters directly to real production logging data interpretation, when the measurement circumstances and PLT strings are similar.

乳腺鳞状细胞癌MRI诊断1例

乳腺的基本构成为乳腺小叶及导管，当其化生成其他类型的组织并发展成为癌时，即称为化生性乳腺癌或化生性癌~[1]。新版WH0乳腺肿瘤分类将乳腺化生性癌(metaplastic carclnoma，MC)分为2大类:纯上皮型和上皮／间叶混合型~[2]。鳞状细胞癌属于纯上皮型。由于有关报道较少，目前人们尚不完全认识或认识不足。
多发性骨骺软骨发育不全1例

多发性骨骺软骨发育不全为常染色体显性遗传的全身性对称性软骨发育障碍，是一种失比例、短肢型侏儒；属于常染色体显性遗传，然而80%～90%病例散发在正常家族中，为基因突变之故口~[1]，突变原因仍不清楚；典型临床表现身材矮小.[取自正文]
