Abstract
OBJECTIVES Bipolar disorder is often misdiagnosed as major depressive disorder. Such misdiagnosis partly depends on the type of treatment setting. This study compared general hospital psychiatric units with psychiatric hospitals in China with respect to basic demographic and clinical characteristics of patients with unrecognised bipolar disorder who are treated for major depressive disorder. METHODS Patients treated for major depressive disorder were consecutively examined in 13 health centres (6 general hospital psychiatric units and 7 psychiatric hospitals) in China. Their socio-demographic and clinical features were recorded using a standardised protocol and data collection procedure. The DSM-IV diagnoses were established using the Mini-International Neuropsychiatric Interview. RESULTS Of the 1487 patients included in the study, 309 (20.8%) were diagnosed with bipolar disorder. There was no significant difference between general hospital psychiatric units and psychiatric hospitals in the ratio of all types of unrecognised bipolar disorders (χ2 = 0.008, degrees of freedom = 1, p = 0.9) and bipolar II disorders (χ2 = 3.1, degrees of freedom = 1, p = 0.08). The proportions of unrecognised bipolar I disorders (χ2 = 4.1, degrees of freedom = 1, p = 0.04) differed significantly between the 2 types of study site. Multivariate analyses showed that patients with bipolar I disorders with more seasonal depressive episodes were more likely to receive treatment in general hospital psychiatric units (odds ratio = 3.3, 95% confidence interval = 1.1-9.8). CONCLUSION Patients with bipolar I disorders receiving treatment in general hospital psychiatric units had different clinical characteristics compared to their counterparts treated in psychiatric hospitals in China.

Trehalose 6-phosphate phosphatase is required for development, virulence and mycotoxin biosynthesis apart from trehalose biosynthesis in Fusarium graminearum. Fungal Genet Biol 2013; 63:24-41.

Abstract
Trehalose 6-phosphate synthase (TPS1) and trehalose 6-phosphate phosphatase (TPS2) are required for trehalose biosynthesis in yeast and filamentous fungi, including Fusarium graminearum. Three null mutants Δtps1, Δtps2 and Δtps1-Δtps2, each carrying either a single deletion of TPS1 or TPS2 or a double deletion of TPS1-TPS2, were generated from a toxigenic F. graminearum strain and were not able to synthesize trehalose. In contrast to its reported function in yeasts and filamentous fungi, TPS1 appeared dispensable for development and virulence. However, deletion of TPS2 abolished sporulation and sexual reproduction; it also altered cell polarity and ultrastructure of the cell wall in association with reduced chitin biosynthesis. The cell polarity alteration was exhibited as reduced apical growth and increased lateral growth and branching with increased hyphal and cell wall widths. Moreover, the TPS2-deficient strain displayed abnormal septum development and nucleus distribution in its conidia and vegetative hyphae. The Δtps2 mutant also had 62% lower mycelial growth on potato dextrose agar and 99% lower virulence on wheat compared with the wild-type. The Δtps1, Δtps2 and Δtps1-Δtps2 mutants synthesized over 3.08-, 7.09- and 2.47-fold less mycotoxins, respectively, on rice culture compared with the wild-type. Comparative transcriptome analysis revealed that the Δtps1, Δtps2 and Δtps1-Δtps2 mutants had 486, 1885 and 146 genotype-specific genes, respectively, with significantly changed expression profiles compared with the wild-type. Further dissection of this pathway will provide new insights into regulation of fungal development, virulence and trichothecene biosynthesis.

Abstract
A sensitive and specific analytical method to detect ubiquitous aflatoxigenic Aspergillus pathogens is essential for monitoring and controlling aflatoxins. Four highly reactive chicken single-chain variable fragments (scFvs) against soluble cell wall proteins (SCWPs) from Aspergillus flavus were isolated by phage display. The scFv antibody AfSA4 displayed the highest activity toward both A. flavus and A. parasiticus and specifically recognized a surface target of their cell walls as revealed by immunofluorescence localization. Molecular modeling revealed a unique compact motif on the antibody surface mainly involving L-CDR2 and H-CDR3. As measured by surface plasmon resonance, AfSA4 fused to alkaline phosphatase had a higher binding capability and 6-fold higher affinity compared with AfSA4 alone. Immunoblot analyses showed that the fusion had good binding capacity to SCWP components from the two fungal species. Direct sandwich enzyme-linked immunosorbent assays with mouse antiaspergillus monoclonal antibody mAb2A8 generated in parallel as a capture antibody revealed that the detection limit of the two fungi was as low as 10(-3) μg/mL, 1000-fold more sensitive than that reported previously (1 μg/mL). The fusion protein was able to detect fungal concentrations below 1 μg/g of maize and peanut grains in both artificially and naturally contaminated samples, with at least 10-fold more sensitivity than that reported (10 μg/g) thus far. Thus, the fusion can be applied in rapid, simple, and specific diagnosis of Aspergillus contamination in field and stored food/feed commodities.

Abstract
The measurement of J/ψ azimuthal anisotropy is presented as a function of transverse momentum for different centralities in Au+Au collisions at sqrt[s(NN)]=200 GeV. The measured J/ψ elliptic flow is consistent with zero within errors for transverse momentum between 2 and 10 GeV/c. Our measurement suggests that J/ψ particles with relatively large transverse momenta are not dominantly produced by coalescence from thermalized charm quarks, when comparing to model calculations.

Abstract
The hickory genus (Carya) contains ca. 17 species distributed in subtropical and tropical regions of eastern Asia and subtropical to temperate regions of eastern North America. Previously, the phylogenetic relationships between eastern Asian and eastern North American species of Carya were not fully confirmed even with an extensive sampling, biogeographic and diversification patterns had thus never been investigated in a phylogenetic context. We sampled 17 species of Carya and 15 species representing all other genera of the Juglandaceae as outgroups, with eight nuclear and plastid loci to reconstruct the phylogeny of Carya. The phylogenetic positions of seven extinct genera of the Juglandaceae were inferred using morphological characters and the molecular phylogeny as a backbone constraint. Divergence times within Carya were estimated with relaxed Bayesian dating. Biogeographic analyses were performed in DIVA and LAGRANGE. Diversification rates were inferred by LASER and APE packages. Our results support two major clades within Carya, corresponding to the lineages of eastern Asia and eastern North America. The split between the two disjunct clades is estimated to be 21.58 (95% HPD 11.07-35.51) Ma. Genus-level DIVA and LAGRANGE analyses incorporating both extant and extinct genera of the Juglandaceae suggested that Carya originated in North America, and migrated to Eurasia during the early Tertiary via the North Atlantic land bridge. Fragmentation of the distribution caused by global cooling in the late Tertiary resulted in the current disjunction. The diversification rate of hickories in eastern North America appeared to be higher than that in eastern Asia, which is ascribed to greater ecological opportunities, key morphological innovations, and polyploidy.

Abstract
Elliptic flow (v(2)) values for identified particles at midrapidity in Au + Au collisions, measured by the STAR experiment in the beam energy scan at RHIC at sqrt[s(NN)] = 7.7-62.4 GeV, are presented. A beam-energy-dependent difference of the values of v(2) between particles and corresponding antiparticles was observed. The difference increases with decreasing beam energy and is larger for baryons compared to mesons. This implies that, at lower energies, particles and antiparticles are not consistent with the universal number-of-constituent-quark scaling of v(2) that was observed at sqrt[s(NN)] = 200 GeV.

Abstract
This paper demonstrates membrane poration of a single suspension cell due to a fast liquid microjet. The jet is formed during the collapse of a laser induced bubble created at a variable stand-off distance from the target cell. The cell is trapped by a converging structure within a microfluidic chip. The asymmetrical growth and collapse of the cavitation bubble next to the cell lead to the microjetting, which deforms and porates the cell membrane. In the experiments, the membrane porations of myeloma cells are probed with the uptake of trypan blue. Time-resolved studies of the diffusion of trypan blue show a marked dependency on the bubble dynamics, i.e. the stand-off distance. The penetration length of the dye increases with shorter distances. Numerical simulations of the diffusion process agree with larger pores formed on the cell membrane. This method allows for a fast, repeatable, and localized rupture of membranes of individual cells in suspension.

Abstract
Type II myosin is required for cytokinesis/septation in yeast and filamentous fungi, including Fusarium graminearum, a prevalent cause of Fusarium head blight in China. A type II myosin gene from the Chinese F. graminearum strain 5035, isolated from infected wheat spikes, was identified by screening a mutant library generated by restriction enzyme-mediated integration. Disruption of the Myo2 gene reduced mycelial growth by 50% and conidiation by 76-fold, and abolished sexual reproduction on wheat kernels. The Δmyo2 mutants also had a 97% decrease in their pathogenicity on wheat, and mycotoxin production fell to just 3.4% of the normal level. The distribution of nuclei and septa was abnormal in the mutants, and the septal ultrastructure appeared disorganized. Time-lapse imaging of septation provided direct evidence that Myo2 is required for septum initiation and formation, and revealed the dynamic behavior of GFP-tagged Myo2 during hyphal and macroconidia development, particularly in the delimiting septum of phialides and macroconidial spores. Microarray analysis identified many genes with altered expression profiles in the Δmyo2 mutant, indicating that Myo2 is required for several F. graminearum developmental processes and biological activities.

Abstract
Fusarium head blight (FHB) caused by Fusarium graminearum infection is a devastating disease of wheat, maize, and other cereals. A previously isolated chicken single-chain Fv antibody (scFv), CWP2, that conferred durable resistance in planta was subjected to directed evolution by error-prone PCR and DNA shuffling, generating a mutated library. Panning of the mutated library against cell wall-bound proteins (CWPs) from F. graminearum by phage display enriched phage clones that were used for a further round of DNA shuffling to construct a combinatorial library comprising 3 × 10(6) variants. Screening of this library by phage display for variants reactive against the CWPs led to the identification of a number of clones. Comparative enzyme-linked immunosorbent assay analyses revealed eight clones exhibiting a higher reactivity than the parent, CWP2, and containing four different single-chain antibody sequences. Surface plasmon resonance measurements confirmed that three mutated scFvs, CWPa, CWPb, and CWPd, displayed 15-fold, 11-fold, and 7-fold higher affinities, respectively, compared with CWP2. Three-dimension modeling of CWPa illustrates a conformational change bringing all six complementary domain regions on the antibody surface in one direction. These results provide promising unique resistance molecules for effective control of FHB and its associated mycotoxins in food/feed chains.

Abstract
The mannan-binding lectin gene (MBL) participates as an opsonin in the innate immune system of mammals, and single nucleotide polymorphisms (SNPs) in MBL cause various immune dysfunctions. In this study, we detected SNPs in MBL2 at exon 1 using polymerase chain reaction single-strand conformation polymorphism analysis and DNA sequencing techniques in 825 Chinese Holstein cows. Four new SNPs with various allele frequencies were also found. The g.1164 G>A SNP was predicted to substitute arginine with glutamine at the N-terminus of the cysteine-rich domain. In the collagen-like domain, SNPs g.1197 C>A and g.1198 G>A changed proline to glutamine, whereas SNP g.1207 T>C was identified as a synonymous mutation. Correlation analysis showed that the g.1197 C>A marker was significantly correlated to somatic cell score (SCS), and the g.1164 G>A locus had significant effects on SCS, fat content, and protein content (P < 0.05), suggesting possible roles of these SNPs in the host response against mastitis. Nine haplotypes and nine haplotype pairs corresponding to the loci of the 4 novel SNPs were found in Chinese Holsteins. Haplotype pairs MM, MN, and BQ were correlated with the lowest SCS; MN with the highest protein yield; MM with the highest protein rate, and MN with the highest 305- day milk yield. Thus, MM, MN, and BQ are possible candidates for marker-assisted selection in dairy cattle breeding programs.

Abstract
This paper demonstrates the optical nonlinearity in opto-mechanical ring resonators that consist of a bus waveguide and two ring resonators, which is induced by the optical gradient force and characterized by the Kerr-like coefficient. Each ring resonator has a free-hanging arc that is perpendicularly deformable by an optical gradient force and subsequently this deformation changes the effective refractive index (ERI) of the ring resonator. The change of the ERI induces optical nonlinearity into the system, which is described by an equivalent Kerr coefficient (Kerr-like coefficient). Based on the experimental results, the Kerr-like coefficient of the ring resonator system falls in the range from 7.64 × 10(-12) to 2.01 × 10(-10) m(2)W(-1), which is at least 6-order higher than the silicon's Kerr coefficient. The dramatically improved optical nonlinearity in the opto-mechanical ring resonators promises potential applications in low power optical signal processing, modulation and bio-sensing.

Abstract
STAR's measurements of directed flow (v1) around midrapidity for π±, K±, KS0, p, and p[over ¯] in Au+Au collisions at √[sNN]=200 GeV are presented. A negative v1(y) slope is observed for most of produced particles (π±, K±, KS0, and p[over ¯]). In 5%-30% central collisions, a sizable difference is present between the v1(y) slope of protons and antiprotons, with the former being consistent with zero within errors. The v1 excitation function is presented. Comparisons to model calculations (RQMD, UrQMD, AMPT, QGSM with parton recombination, and a hydrodynamics model with a tilted source) are made. For those models which have calculations of v1 for both pions and protons, none of them can describe v1(y) for pions and protons simultaneously. The hydrodynamics model with a tilted source as currently implemented cannot explain the centrality dependence of the difference between the v1(y) slopes of protons and antiprotons.

Abstract
We report transverse momentum (p(T)≤15 GeV/c) spectra of π(±), K(±), p, p[over ¯], K(S)(0), and ρ(0) at midrapidity in p+p and Au+Au collisions at √S(NN)=200 GeV. Perturbative QCD calculations are consistent with π(±) spectra in p+p collisions but do not reproduce K and p(p[over ¯]) spectra. The observed decreasing antiparticle-to-particle ratios with increasing p(T) provide experimental evidence for varying quark and gluon jet contributions to high-p(T) hadron yields. The relative hadron abundances in Au+Au at p(T)≳8 GeV/c are measured to be similar to the p+p results, despite the expected Casimir effect for parton energy loss.

Abstract
We report new STAR measurements of midrapidity yields for the Λ, Λ[over ¯], K(S)(0), Ξ(-), Ξ[over ¯](+), Ω(-), Ω[over ¯](+) particles in Cu+Cu collisions at √S(NN)==200 GeV, and midrapidity yields for the Λ, Λ[over ¯], K(S)(0) particles in Au+Au at √S(NN)==200 GeV. We show that, at a given number of participating nucleons, the production of strange hadrons is higher in Cu+Cu collisions than in Au+Au collisions at the same center-of-mass energy. We find that aspects of the enhancement factors for all particles can be described by a parametrization based on the fraction of participants that undergo multiple collisions.

Abstract
The Fusarium graminearum species complex (Fg complex) consists of phylogenetically distinct species some of which cannot be discriminated based on their morphology. Their chemotypes and geographic distributions are dramatically different, and these highlight the challenges that Fusarium head blight (FHB) poses to plant disease specialists and plant breeders, thereby requiring that quarantine officials employ molecular diagnostic tools in their active surveillance programs. Molecular marker technologies play essential roles in species identification of the Fg complex, and they are being used widely to assess the genetic diversity of the clade. The utility, applicability and limitations of molecular methods for assessing the population structure and genetic diversity within the Fg complex are discussed with suitable examples. Knowledge gained from these studies will provide a baseline for monitoring changes in FHB pathogen diversity and mycotoxin potential over time, both of which are critical to the ultimate control and elimination of this economically devastating disease.

Abstract
A method for on-demand droplet fusion in a microfluidic channel is presented using the flow created from a single explosively expanding cavitation bubble. We test the technique for water-in-oil droplets, which are produced using a T-junction design in a microfluidic chip. The cavitation bubble is created with a pulsed laser beam focused into one droplet. High-speed photography of the dynamics reveals that the droplet fusion can be induced within a few tens of microseconds and is caused by the rapid thinning of the continuous phase film separating the droplets. The cavitation bubble collapses and re-condenses into the droplet. Droplet fusion is demonstrated for static and moving droplets, and for droplets of equal and unequal sizes. Furthermore, we reveal the diffusion dominated mixing flow and the transport of a single encapsulated cell into a fused droplet. This laser-based droplet fusion technique may find applications in micro-droplet based chemical synthesis and bioassays.

Abstract
We report the first measurement of the parity-violating single-spin asymmetries for midrapidity decay positrons and electrons from W+ and W- boson production in longitudinally polarized proton-proton collisions at sqrt[s] = 500 GeV by the STAR experiment at RHIC. The measured asymmetries, A(L)(W+) = -0.27 ± 0.10(stat.) ± 0.02(syst.) ± 0.03(norm.) and A(L)(W-) = 0.14 ± 0.19(stat.) ± 0.02(syst.) ± 0.01(norm.), are consistent with theory predictions, which are large and of opposite sign. These predictions are based on polarized quark and antiquark distribution functions constrained by polarized deep-inelastic scattering measurements.

Abstract
This paper reports a tunable visual color filter based on a microfluidic transmission grating. The grating lines are formed by the microflows in an array of evenly spaced straight microchannels. In experimental study, the transmission of white light measures a shift of visual color from red to blue in the zeroth order diffraction in response to a change of the refractive index from 1.3290 to 1.3782 in the microflows. The merit of large tunability of transmission peak (Δλ=408 nm) makes this grating potential for various applications in biological and chemical measurements, such as space- and time-resolving micropattern spectrophotometers and separation of the fluorescence from the excitation.

Abstract
OBJECTIVE Intravenous administration of recombinant tissue plasminogen activator (rtPA) is known as the only approved treatment for acute ischemic stroke. However, it is still controversial whether acute ischemic stroke patients with atrial fibrillation should receive rtPA therapy. METHODS We studied 99 patients altogether who belonged to three different groups based on the patient characteristics: (1) atrial fibrillation rtPA-treated group consisting of 22 ischemic stroke patients with atrial fibrillation treated with rtPA within 4.5 hours after the onset of stroke; (2) atrial fibrillation non-rtPA-treated group consisting of 44 acute ischemic stroke patients with atrial fibrillation matching in age and baseline National Institutes of Health Stroke Scale (NIHSS); (3) the non-atrial fibrillation rtPA-treated group consisting of 33 patients without atrial fibrillation treated with rtPA. RESULTS The median time for the administration of rtPA was 199.6 +/- 50.0 minutes. More patients had favorable outcomes (90 day modified Rankin Scale 0-1) in the atrial fibrillation rtPA-treated group than the atrial fibrillation non-rtPA-treated group (36.4 versus 13.6%; odds ratio=2.667; 95% confidence interval: 1.056-6.735; p=0.033). The mortality at day 90 was lower in the rtPA-treated group than the non-rtPA-treated group (18.2 versus 20.5%; p=0.827), although the incidence of symptomatic intracranial hemorrhage was higher (18.2 versus 6.8%; p=0.184). Patients in the atrial fibrillation rtPA-treated group had fewer favorable outcomes than non-atrial fibrillation rtPA-treated group (36.4 versus 51.6%; p=0.076), but their baseline NIHSS was higher (12.0 +/- 7.1 versus 9.1 +/- 7.3; p=0.161). CONCLUSION As compared with non-rtPA-treated patients, rtPA treated within 4.5 hours after the onset of stroke significantly improved clinical outcomes in atrial fibrillation patients. Thrombolytic treatment increases intracranial hemorrhage rate but does not increase mortality.

Abstract
Prion protein (PRNP) gene has been located at position q17 of chromosome 13 in cattle. The polymorphisms of PRNP gene might be associated with BSE susceptibility. In the present work, we investigated the polymorphisms of PRNP gene, including SNP in exon 3, 23-bp indel in promoter region, 12-bp indel in intron 1 in 2 Chinese indigenous cattle breeds of northeast China. Eighty-six animals from Yanbian (34) and Chinese Red Steppes (52) were genotyped at PRNP locus by analyzing genomic DNA. A total of 4 single nucleotide polymorphism (SNP) sites were revealed in the PRNP gene exon 3 of the 2 cattle breeds investigated. Three of these SNPs were non-synonymous mutations that resulted in the amino acid exchanges (K119N, S154N, and M177V), and one is silent nucleotide substitutions (A234G). The two amino acid mutations of S154N and M177V were detected only in Yanbian with a very low frequency (0.0147), and they appears to be absent in Chinese Red Steppes. The average gene heterozygosity (He), effective allele numbers (Ne), Shannon's information index (I) and polymorphism information content (PIC) were 0.3088, 1.5013, 0.3814 and 0.2000 in Yanbian, respectively, being relatively higher than that of Chinese Red Steppes (0.2885, 1.4985, 0.3462 and 0.1873, respectively). In 23-bp indel and 12-bp indel loci, three different genotypes were identified in both Yanbian and Chinese Red Steppes breeds. Based 23- and 12-bp indels, four haplotypes was constructed in the 2 Chinese cattle breeds, of which the 23-bp (-)/12-bp (-) was main haplotypes accounting for more than 50% of the total in both Yanbian and Chinese Red Steppes breeds. These results might be useful in understanding the genetic characteristics of PRNP gene in Chinese indigenous cattle breeds.

Abstract
The contribution of B meson decays to nonphotonic electrons, which are mainly produced by the semileptonic decays of heavy-flavor mesons, in p + p collisions at √s=200 GeV has been measured using azimuthal correlations between nonphotonic electrons and hadrons. The extracted B decay contribution is approximately 50% at a transverse momentum of pT≥5 GeV/c. These measurements constrain the nuclear modification factor for electrons from B and D meson decays. The result indicates that B meson production in heavy ion collisions is also suppressed at high pT.

Abstract
We report the first measurements of the kurtosis (κ), skewness (S), and variance (σ2) of net-proton multiplicity (Np-Np) distributions at midrapidity for Au+Au collisions at square root of s(NN)=19.6, 62.4, and 200 GeV corresponding to baryon chemical potentials (μB) between 200 and 20 MeV. Our measurements of the products κσ2 and Sσ, which can be related to theoretical calculations sensitive to baryon number susceptibilities and long-range correlations, are constant as functions of collision centrality. We compare these products with results from lattice QCD and various models without a critical point and study the square root of s(NN) dependence of κσ2. From the measurements at the three beam energies, we find no evidence for a critical point in the QCD phase diagram for μB below 200 MeV.

Abstract
ABSTRACT One plant genotype displays a resistance phenotype at one development stage but a susceptible reaction to the same pathogen at another stage, which is referred to here as resistance inversion. In wheat, Fusarium head blight (FHB)-resistant cv. Sumai3 showed a Fusarium seedling blight (FSB)-susceptible reaction whereas FHB-susceptible cv. Annong8455 exhibited FSB resistance when challenged with a Fusarium asiaticum strain that produces deoxynivalenol (DON). The resistance to FHB and FSB in wheat was closely associated with expression of a plant cytochrome P450 gene in response to FHB pathogens and mycotoxins. Quantitative real-time polymerase chain reaction analyses showed that expression of nine defense-related genes in spikes and seedlings was induced by the fungal infection, in which a massive accumulation of a plant cytochrome P450 gene, CYP709C1, was clearly associated with the resistance reaction in both seedling and spike. The FHB-resistant Sumai3 accumulated 7-fold more P450 transcripts than did the FHB-susceptible Annong8455, while 84-fold more P450 transcripts were accumulated in the FSB-resistant Annong8455 than the FSB-susceptible Sumai3. A Fusarium strain with a disrupted Tri5 gene, which is not able to produce the first enzyme essential for trichothecene mycotoxin biosynthesis, also induced more P450 transcripts in FHB- and FSB-resistant cultivars. The fungal activation of the P450 gene was more profound in the FSB-resistant reaction than the FHB-resistant reaction relative to their susceptible counterparts. DON triggered a differential expression of the P450 gene with comparable patterns in spikes and seedlings in a resistance-dependent manner. These results may provide a basis for dissecting mechanisms underlying FHB and FSB resistance reactions in wheat and revealing functions of the cytochrome P450 in plant detoxification and defense.

Abstract
Rice paddy soils undergo several cycles of drying and wetting during a growing season. A laboratory study was conducted to determine the effect of soil moisture conditions on the distribution and kinetics of extractable and bound residues of 14C-metsulfuron-methyl in six Chinese paddy soils during 84 d of incubation at 15 degrees C with moisture contents varying from 20 to 50% of the field water-holding capacity. The amount of extractable residues consistently increased and bound residues decreased with increasing soil moisture content. At the end of the incubation experiments, extractable residues and bound residues accounted for 34.5 to 84.4% and 11.6 to 53.3% of applied radioactivity in soils, respectively. Soil pH and soil microbial biomass carbon were the most predominant factors affecting the formation and relative distribution of herbicide residues between extractable and bound residue forms. In high-pH soils, bound residues decreased and extractable residues increased, suggesting an increased leaching risk for metsulfuron-methyl in alkaline soils. High precipitation rates, along with the common practice of liming in southeastern China, may lead to enhanced herbicide leaching as well as phytotoxicity to rotation plants and should be considered in overall pest management practices.

Abstract
Fusarium graminearum clade pathogens cause Fusarium head blight (FHB) or scab of wheat and other small cereal grains, producing different kinds of trichothecene mycotoxins that are detrimental to human and domestic animals. Type B trichothecene mycotoxins such as deoxynivalenol, 3-acetyldeoxynivalenol (3-AcDON), 15-acetyldeoxynivalenol (15-AcDON) and nivalenol (NIV) are the principal Fusarium mycotoxins reported in China, as well as in other countries. A genomic polymerase chain reaction (PCR) to predict chemotypes was developed based on the structural gene sequences of Tri13 genes involved in trichothecene mycotoxin biosynthesis pathways. A single pair of primers derived from the Tri13 genes detected a 583 bp fragment from 15-AcDON-chemotypes, a 644 bp fragment from 3-AcDON-chemotypes and an 859 bp fragment from NIV-producing strains. Fusarium strains from China, Nepal, USA and Europe were identified by this method, revealing their mycotoxin chemotypes identical to that obtained by chemical analyses of HPLC or GC/MS and other PCR assays. The mycotoxin chemotype-specific fragments were amplified from a highly variable region located in Tri13 genes with three deletions for 15-AcDON-chemotypes, two deletions for 3-AcDON-chemotypes and no deletion for NIV-producers. This PCR assay generated a single amplicon and thus should be more reliable than other PCR-based assays that showed the absence or presence of a PCR fragment since these assays may generate false-negative results. The results with strains from several different countries as well as from different hosts further indicated that this method should be globally applicable. This is a rapid, reliable and cost-effective method for the identification of type B trichothecene mycotoxin chemotypes in Fusarium species and food safety controls.

Abstract
Fusarium mycotoxins directly accumulated in grains during the infection of wheat and other cereal crops by Fusarium head blight (FHB) pathogens are detrimental to humans and domesticated animals. Prevention of the mycotoxins via the development of FHB-resistant varieties has been a challenge due to the scarcity of natural resistance against FHB pathogens. Various antibodies specific to Fusarium fungi and mycotoxins are widely used in immunoassays and antibody-mediated resistance in planta against Fusarium pathogens has been demonstrated. Antibodies fused to antifungal proteins have been shown to confer a very significantly enhanced Fusarium resistance in transgenic plants. Thus, antibody fusions hold great promise as an effective tool for the prevention of mycotoxin contaminations in cereal grains. This review highlights the utilization of protective antibodies derived from phage display to increase endogenous resistance of wheat to FHB pathogens and consequently to reduce mycotoxins in field. The role played by Fusarium-specific antibody in the resistance is also discussed.

Abstract
Fusarium head blight (FHB) or scab of wheat is a devastating disease in warm and humid regions at wheat-flowering periods worldwide. Natural resistance against FHB pathogens is inadequate and the development of FHB-resistant wheat cultivars has been a challenge. Expression of pathogen-specific antibodies in plants has been proposed as a strategy for crop protection. In this study, an antibody fusion protein comprising a Fusarium-specific recombinant antibody derived from chicken and an antifungal peptide from Aspergillus giganteus was expressed in wheat as a method for protecting plants against FHB pathogens. Plants expressing the antibody fusion displayed a very significantly enhanced resistance in T2 and T3 generations upon single-floret inoculation with the macroconidia of Fusarium asiaticum, the predominant species causing FHB in China, indicating a type II resistance. Spraying inoculation further revealed an enhanced type I resistance in the transgenic wheat plants. Remarkably, more grains were produced in the transgenic plants than the nontransgenic controls. Our results demonstrated that the antibody fusion protein may be used as an effective tool for the protection of crops against FHB pathogens.

Abstract
Ultrafast high-density photonic integrated circuit devices (PICDs) are not easily obtained using traditional index-guiding mechanisms. In this paper, photonic bandgap crystal resonator enhanced, laser-controlled modulations of optical interconnect PICDs were achieved in slab-type mix-guiding configuration - through developed CMOS-compatible processing technologies. The devices, with smallest critical dimensions of 90 nm have footprints of less than 5 x 5 microm(2). Quality-factors an order larger than previously realized was achieved. Through use of effective coupling structures; simultaneous alignment for probing and pumping laser beams, optical measurements of both instantaneous free carriers induced device modulations were obtained together with thermo-optical effects characterizations.

Abstract
OBJECTIVE To examine the association between pregnancy-induced hypertension (PIH) and small-for-gestational-age babies (SGA) in a Chinese population. METHODS Subjects were women who delivered a singleton baby (gestational weeks: equal to or greater than 28, and less than 42) in four cities or counties in Jiangsu and Zhejiang provinces, China, during the period of 1995 - 2000. A total number of 93 743 women were included. Incidence of SGA was calculated and compared between women with or without PIH and between groups with different severities of PIH. Multiple logistic regression was used to address the relationship between PIH and SGA while controlling for maternal age, occupation, education, parity, BMI, anemia, premature rupture of membranes and fetal sex. The association between PIH and SGA was also examined according to preterm or term delivery. RESULTS The incidence of SGA in women with PIH (6.0%) was higher than women without (4.5%), and the incidence increased with severities of PIH. The adjusted relative risk rates (95% CI) of SGA in women with mild,moderate and severe PIH were 1.17 (1.01-1.34), 1.69 (1.33-2.14), and 3.50 (2.57-4.77), respectively, when confounders were controlled for. The risk ratios of SGA in women with PIH among women who delivered a preterm baby were higher than those among women who delivered a term baby. CONCLUSION There seemed a statistical association between PIH and SGA and women with PIH having higher incidence of SGA than those without PIH.

Abstract
A large number of isolates from the Fusarium graminearum clade representing all regions in China with a known history of Fusarium head blight (FHB) epidemics in wheat were assayed using PCR to ascertain their trichothecene mycotoxin chemotypes and associated phylogenetic species and geographical distribution. Of the 299 isolates assayed, 231 are from F. asiaticum species lineage 6, which produce deoxynivalenol and 3-acetyldeoxynivalenol (3-AcDON); deoxynivalenol and 15-acetyldeoxynivalenol (15-AcDON); and nivalenol and 4-acetylnivalenol (NIV) mycotoxins, with 3-AcDON being the predominant chemotype. Ninety-five percent of this species originated from the warmer regions where the annual average temperatures were above 15 degrees C, based on the climate data of 30 y during 1970-1999. However, 68 isolates within F. graminearum species lineage 7 consisted only of 15-AcDON producers, 59% of which were from the cooler regions where the annual average temperatures were 15 degrees C or lower. Identification of a new subpopulation of 15-AcDON producers revealed a molecular distinction between F. graminearum and F. asiaticum that produce 15-AcDON. An 11-bp repeat is present in F. graminearum within their Tri7 gene sequences but is absent in F. asiaticum, which could be directly used for differentiating the two phylogenetic species of the F. graminearum clade.

Abstract
By combining the constraints of charge symmetry with new chiral extrapolation techniques and recent low-mass quenched lattice QCD simulations of the individual quark contributions to the electric charge radii of the baryon octet, we obtain an accurate determination of the strange electric charge radius of the proton. While this analysis provides a value for G(E)(s)(Q(2) = 0.1 GeV(2)) in agreement with the best current data, the theoretical error is comparable with that expected from future HAPPEX results from JLab. Together with the earlier determination of G(M)(s), this result considerably constrains the role of hidden flavor in the structure of the nucleon.

Abstract
A 1320-bp cDNA containing the full coding region of the porcine succinate dehydrogenase complex, subunit D (SDHD) gene was obtained by random sequencing of clones from a Chinese Tongcheng pig 55-day fetal longissimus dorsi muscle cDNA library. Analysis of the SDHD gene across the INRA-University of Minnesota porcine radiation hybrid panel indicated close linkage with microsatellite marker SW2401, located on SSC9p21. The open reading frame of this cDNA covers 480 bp and encodes 159 amino acids. The deduced porcine amino acid sequence showed greater similarity with human and bovine protein sequences than with those from mouse and rat. The BLAST analysis of the porcine SDHD to NCBI identified Unigene Cluster Ssc.2586. Possible single nucleotide polymorphisms (SNP) were identified by alignment of expressed sequence tags in the cluster. The polymerase chain reaction (PCR) single strand conformation polymorphism, sequencing, and PCR restriction fragment length polymorphism were used to confirm and detect a synonymous polymorphic MboI site within the open-reading frame. Allele frequencies of this SNP were investigated in two commercial and five Chinese local pig breeds. These five Chinese breeds had very high frequencies for one allele, whereas frequencies of both alleles were intermediate in Large White and Duroc. An association analysis suggested that different SDHD genotypes have significant differences in loin-muscle area (P < 0.01).

Abstract
AIM: To reveal the liver regeneration (LR) and its control as well as the occurrence of liver disease and to study the gene expression profiles of 551 genes after partial hepatectomy (PH) in regenerating rat livers.
METHODS: Five hundred and fifty-one expressed sequence tags screened by suppression subtractive hybridization were made into an in-house cDNA microarray, and the expressive genes and their expressive profiles in regenerating rat livers were analyzed by microarray and bioinformatics.
RESULTS: Three hundred of the analyzed 551 genes were up- or downregulated more than twofolds at one or more time points during LR. Most of the genes were up- or downregulated 2-5 folds, but the highest reached 90 folds of the control. One hundred and thirty-nine of them showed upregulation, 135 displayed downregulation, and up or down expression of 26 genes revealed a dependence on regenerating livers. The genes expressed in 24-h regenerating livers were much more than those in the others. Cluster analysis and generalization analysis showed that there were at least six distinct temporal patterns of gene expression in the regenerating livers, that is, genes were expressed in the immediate early phase, early phase, intermediate phase, early-late phase, late phase, terminal phase.
CONCLUSION: In LR, the number of down-regulated genes was almost similar to that of the upregulated genes; the successively altered genes were more than the rapidly transient genes. The temporal patterns of gene expression were similar 2 and 4 h, 12 and 16 h, 48 and 96 h, 72 and 144 h after PH. Microarray combined with suppressive subtractive hybridization can effectively identify the genes related to LR.

Abstract
AIM: To identify the genes differentially expressed in the regenerating rat liver of 0-4-8-12 h short interval successive partial hepatectomy (SISPH) and to analyze their expression profiles.
METHODS: Five hundred and fifty-one elements screened from subtractive cDNA libraries were made into a cDNA microarray (cDNA chip). Extensive gene expression analysis following 0-4-8-12 h SISPH was conducted by microarray.
RESULTS: One hundred and eighty-three elements were selected, which were either up- or down-regulated more than 2-fold at one or more time points after SISPH. Cluster analysis and generalization analysis showed that there were five distinct temporal patterns of gene expression. Eighty-six genes were unreported, associated with liver regeneration (LR).
CONCLUSION: Microarray analysis shows that the down regulated genes are much more than the up-regulated ones in SISPH; the numbers of genes expressed consistently are fewer than that expressed immediately; the genes expressed in high abundance are much fewer than that increased 2-5-fold. The comparison of SISPH with partial hepatectomy (PH) shows that the expression trends of most genes in SISPH and in PH are similar, but the expression of 43 genes is specifically altered in SISPH.

Abstract
Vaccination with antigenic peptide-pulsed antigen-presenting cells (APC) represents an attractive approach for therapy for cancer and diseases caused by intracellular infections. It has been suggested that sufficient stable MHC/peptide complexes on the surface of APC might play an important role in the generation of antitumor and antiviral immunity in vivo. In this study, we observed that exogenous peptides that were artificially fused with an endoplasmic reticulum (ER) retrieval signal, a C-terminal Lys-Asp-Glu-Leu sequence, could be efficiently presented by intracellular MHC class I molecules in a TAP- and proteasome-independent, but brefeldin A-sensitive manner. The APC retained the capacity to display surface MHC/peptide complexes for a prolonged period. In addition, our results show that vaccination with DC bearing our fusion peptides induced greatly enhanced specific CTL response, and resulted in significant inhibition of tumor growth. Thus, the ER retrieval signal modification can be regarded as a novel method for targeting exogenous peptides into the intracellular MHC class I presentation pathway, and may improve the clinical utility of vaccines based on synthetic peptide pulsed DC.

Abstract
AIM: To identify the genes expressed differentially in the regenerating rat liver in a short interval successive partial hepatectomy (SISPH), and to analyze their expression profiles.
METHODS: Five hundred and fifty-one elements selected from subtractive cDNA libraries were conformed to a cDNA microarray (cDNA chip). An extensive gene expression analysis following 0-36-72-96-144 h SISPH was performed by microarray.
RESULTS: Two hundred and sixteen elements were identified either up- or down-regulated more than 2-fold at one or more time points of SISPH. By cluster analysis and generalization analysis, 8 kinds of ramose gene expression clusters were generated in the SISPH. Of the 216 elements, 111 were up-regulated and 105 down-regulated. Except 99 unreported genes, 117 reported genes were categorized into 22 groups based on their biological functions. Comparison of the gene expression in SISPH with that after partial hepatectomy (PH) disclosed that 56 genes were specially altered in SISPH, and 160 genes were simultaneously up-regulated or down-regulated in SISPH and after PH, but in various amount and at different time points.
CONCLUSION: Genes expressed consistently are far less than that intermittently; the genes strikingly increased are much less than that increased only 2-5 fold; the expression trends of most genes in SISPH and in PH are similar, but the expression of 56 genes is specifically altered in SISPH. Microarray combined with suppressive subtractive hybridization can in a large scale effectively identify the genes related to liver regeneration.

AIM: To investigate the function state of epitope-specific cytotoxic T lymphocytes (CTLs) in chronic hepatitis B infection
METHODS: The study was performed to quantify the HBV specific CTL directly in vitro by HLA-A2 tetrameric complexes for core 18-27 (Tc 18-27), envelope 183-191 (Te 183-191), envelope 335-343 (Te 335-343), and polymerase 575-583 (Tp 575-583) in active chronic hepatitis patients, and then the correlation of HBV epitope-specific CTL between serum HBV DNA loads or alanine aminotransmerase (ALT) levels were analyzed by multiple regression analysis.
RESULTS: It was found that there were multiple CTLs responses in active chronic hepatitis patients. The frequency of Tc18-27 response was higher than the other three epitope-specific CTLs. No significant correlation was found either between the frequency of HBV specific CD8+ T cells and the viral load, or the frequency of HBV specific CD8+ T cells and the levels of alanine transaminase.
CONCLUSION: The frequencies of HBV-specific T cells are not determinant of immune-mediated protection in HBV infection and the existence of epitope-specific HBV CTLs is not directly correlated to hepatocytic injury.

Abstract
AIM: To identify genes related to rat liver regeneration (LR) after 0-36-40-44h short interval successive partial hepatectomy (SISPH) and to analyze their action and expression profile in LR.
METHODS: A cDNA microarray containing 551 elements (liver chip) was made to analyze extensively expression changes of them in 0-36-40-44h SISPH, which were selected from subtractive cDNA libraries of the LR. Cluster analysis of these gene expression profile was performed by Genemath.
RESULTS: Among the selected 551 cDNA, 157 were up- ordown-regulated more than twofold at one or more time points. Of the 157 elements, 86 were up-regulated and 71 down-regulated, and 70 were not reported and 87 were reported, which had not been previously reported to be involved in LR. By cluster analysis and generalization analysis, 6 distinct temporal induction or suppression patterns showed that immediate induction, intermediate induction, late induction, immediate suppression, intermediate suppression, and late suppression. Comparison of the gene expression in SISPH with after PH found that 38 genes were specially altered in SISPH, and the expression trends for other 119 genes were similar between SISPH and PH, except of the various abundance at the different time points.
CONCLUSION: In 0-36-40-44h SISPH, the numbers of the up-regulated and down-regulated genes show no apparent difference. The genes expressed lately are more than that immediately, and much more than that intermediately. The genes expressed abundantly are much less than that increased 2-5 folds.

Abstract
OBJECTIVE To investigate the natural and socio-economical environment in the areas where Anopheles anthropophagus distributed in Hubei Province. METHODS 5% of the villages in distribution area of An. anthropophagus were randomly selected for the investigation which included vegetation, soil, water, temperature, farming, resting places of the mosquito. RESULTS The vegetation of An. anthropophagus area consisted of forest, bush, sod and crops. The area was densely covered with river, ditches and ponds, the water pH being 6.1-7.7. The soil texture was either yellow, yellow brown, grey or black, contained 2.72% organic material. There were one or two seasons of rice plantation in the area and the amount of insecticide used was 0.828 kg/mu in the rice field. The annual average temperature was 16.9 degrees C and the humidity was 76.9%. The breed period of An. anthropophagus was from June to September. There are two peaks of mosquito population in area with two seasons of rice plantation, and one peak in one rice season. The composition of An. anthropophagus resting in households, cowsheds and pigpens was 80.9%, 12.2% and 6.0%, respectively. CONCLUSION The distribution of An. anthropophagus was in point, flaky or belt form in low hill, hillock, shallow hilly plain. These areas were full of vegetation and source of water, the principal crop was single cropping of rice, and soil texture is yellow or yellow brown. The major resting place of the mosquito was human dwellings.
