Abstract
Recently, murine kobuvirus (MuKV), a novel member of the family Picornaviridae, was identified in faecal samples of Rattus norvegicus in China. The limited information on the circulation of MuKV in other murine rodent species prompted us to investigate its prevalence and conduct a genetic characterization of MuKV in Rattus losea, Rattus tanezumi and Rattus norvegicus in China. Between 2015 and 2017, 243 faecal samples of these three murine rodent species from three regions in southern China were screened for the presence of MuKV. The overall prevalence was 23.0% (56/243). Three complete MuKV polyprotein sequences were acquired, and the genome organization was determined. Phylogenetic analyses suggested that our sequences were closely related to Chinese strains and belong to the species Aichivirus A in the genus Kobuvirus. Additional studies are required to understand the true prevalence of MuKV in murine rodent populations in China.

Abstract
Background The patterns of leukemia burden have dramatically changed in recent years. This study aimed to estimate the global trends of leukemia‐related death and disability‐adjusted life‐years (DALYs) from 1990 to 2017. Methods The data was acquired from the latest version of the Global Burden of Disease (GBD) study. Estimated annual percentage changes (EAPCs) were calculated to estimate the trend of age‐standardized rate (ASR) of death and DALYs due to leukemia and its main subtypes from 1990 to 2017. Results Globally, the numbers of death and DALYs due to leukemia were 347.58 × 103 (95% uncertainty interval [UI] = 317.26 × 103‐364.88 × 103) and 11975.35 × 103 (95% UI = 10749.15 × 103‐12793.58 × 103) in 2017, with a 31.22% and 0.03% increase in absolute numbers from 1990 to 2017, respectively. Both of their ASR showed decreasing trends from 1990 to 2017 with the EAPCs being −1.04 (95% confidence interval [CI] = (−1.10‐−0.99) and −1.52 (95% CI = −1.59‐−1.44), respectively. Globally, the most pronounced decreasing trend of death and DALYs occurred in chronic myeloid leukemia with EAPCs of −2.76 (95% CI = −2.88‐−2.64) and −2.84 (95% CI = −2.97‐−2.70), respectively, while the trend increased in acute myeloid leukemia. The death and DALYs of leukemia decreased in most areas and countries with high socio‐demographic index (SDI) including Bahrain, Finland, and Australia. Conclusions The disease burden of death and DALYs due to leukemia decreased globally, and for most regions and countries from 1990 to 2017. However, the leukemia burden is still a substantial challenge globally and required adequate and affordable medical resources to improve the survival and quality of life of leukemia patients.

Abstract
OBJECTIVES To assess the effects of electroacupuncture (EA) at the Zusanli (ST36), Guanyuan (CV4), Zhongwan (CV12), and Fenglong (ST40) acupoints on sirtuin 1 (SIRT1) and glucose transporter type 4 (GLUT4) expression in high-fat diet (HFD)-induced insulin-resistant (IR) rats. METHODS Wistar rats were divided into normal control (NC), HFD, and HFD+EA groups. NC rats were fed a standard chow diet and did not receive EA. After being fed an HFD for eight weeks, rats in the HFD+EA group received EA at 2 Hz five times a week for eight weeks. Rats in the HFD group did not receive EA. RESULTS In HFD-induced IR rats, EA inhibited body weight increase and water intake, which were observed in HFD rats. EA had no effect on fasting blood glucose and postprandial blood sugar levels. Intraperitoneal insulin tolerance testing revealed that EA enhanced insulin sensitivity in HFD-induced IR rats. Compared with NC rats, SIRT1 and GLUT4 were downregulated in the quadriceps femoris of HFD-fed rats but were increased after eight weeks of EA stimulation. CONCLUSIONS EA enhanced HFD-induced insulin resistance by activating SIRT1 and GLUT4 in the quadriceps femoris. These results provide powerful evidence supporting the beneficial effects of EA on HFD-induced insulin resistance.

Abstract
A new brain-cell line derived from Japanese flounder Paralichthys olivaceus (POBC) was established. POBC was subcultured for 67 passages over the course of 420 days. The cultured cells were primarily epithelioid-like. Chromosome analysis revealed the cell line to possess the normal P. olivaceus diploid karyotype of 2n = 48t (telocentric chromosomes). The cells exhibited the astrocyte marker glial fibrillary acidic protein by immunocytochemistry, and significant fluorescent signals were observed when the cells were transfected with green fluorescent protein reporter plasmid. The established POBC would be ideal material for the study of function of fish ependyma, the central neuroendocrine system and endocrine disruptors in the marine environment.

Abstract
To better understand the effects of DNA methylation on the expression patterns of dmrt1 (Doublesex and Mab-3-related transcription factor 1) and cyp19a (Cytochrome P450 19a) in the Japanese flounder Paralichthys olivaceus, quantitative expressions, cellular distributions and cytosine-p-guanine (CpG) methylation patterns of these two genes in the gonads were analysed. The results showed that P. olivaceus dmrt1 expression was 70 times higher in the testis than in the ovary (P < 0·05). Its mRNA was detected clearly in spermatocytes and Sertoli cells of the testis, but weakly in the ovary. Paralichthys olivaceus cyp19a expression was 40 times higher in the ovary than in the testis (P < 0·01). Its mRNA was detected clearly in follicular cells of the ovary, but weakly in spermatocytes of the testis. The dmrt1 promoter CpGs were not methylated in the testis, whereas 57·69% were methylated in the ovary. For the cyp19a promoter CpGs, 97·5% were methylated in the testis and 73·33% were methylated in the ovary. These findings demonstrate that P. olivaceus dmrt1 and cyp19a are sex-related genes with sexual dimorphic expression, CpG methylation levels of the two genes are consistent with their expression quantities, and this epigenetic modification can influence the differential expression of genes in the gonads of P. olivaceus.

Abstract
Indirect immunofluorescence staining was used to detect cytological changes of isolated blastodisks during mitosis of flounder haploid eggs treated with hydrostatic pressure. Changes in microtubule structure and expected cleavage suppression were observed from blastodisk formation to the third cell cycle, with obvious differences between treated and control eggs. In most eggs, microtubules were disassembled and the nucleation capacity of the centrosome was temporarily inhibited after pressure treatment. Within 15-20 min after treatment, the nucleation capacity of the centrosome began to gradually recover, with slow regeneration of microtubules; approximately 25 min after treatment, the nucleation capacity of the centrosome recovered completely, regenerated distinct bipolar spindles, and the first mitosis ensued. During the second cell cycle, approximately 61% of the embryos were at the two-cell stage, with a monopolar spindle in each blastomere; that treatment was effective was based on second cleavage blockage. Approximately 15% of the eggs still remained at the one-cell stage and had a monopolar spindle (treatment was effective, according to the general model of first cleavage blockage). However, treatment was ineffective in approximately 15% of the embryos (bipolar spindle in each blastomeres) and in another 8% (bipolar spindle in one of the two blastomeres and a monopolar spindle in the other; both mechanisms operating in different parts of the embryo). This is the first report elucidating mitotic gynogenetic diploid induction by hydrostatic pressure in marine fishes and provides a cytological basis for developing an efficient method of inducing mitotic gynogenesis in olive flounder.

Abstract
The US Wheat Genome Project, funded by the National Science Foundation, developed the first large public Triticeae expressed sequence tag (EST) resource. Altogether, 116,272 ESTs were produced, comprising 100,674 5' ESTs and 15 598 3' ESTs. These ESTs were derived from 42 cDNA libraries, which were created from hexaploid bread wheat (Triticum aestivum L.) and its close relatives, including diploid wheat (T. monococcum L. and Aegilops speltoides L.), tetraploid wheat (T. turgidum L.), and rye (Secale cereale L.), using tissues collected from various stages of plant growth and development and under diverse regimes of abiotic and biotic stress treatments. ESTs were assembled into 18,876 contigs and 23,034 singletons, or 41,910 wheat unigenes. Over 90% of the contigs contained fewer than 10 EST members, implying that the ESTs represented a diverse selection of genes and that genes expressed at low and moderate to high levels were well sampled. Statistical methods were used to study the correlation of gene expression patterns, based on the ESTs clustered in the 1536 contigs that contained at least 10 5' EST members and thus representing the most abundant genes expressed in wheat. Analysis further identified genes in wheat that were significantly upregulated (p < 0.05) in tissues under various abiotic stresses when compared with control tissues. Though the function annotation cannot be assigned for many of these genes, it is likely that they play a role associated with the stress response. This study predicted the possible functionality for 4% of total wheat unigenes, which leaves the remaining 96% with their functional roles and expression patterns largely unknown. Nonetheless, the EST data generated in this project provide a diverse and rich source for gene discovery in wheat.

Abstract
544 Background: Trastuzumab (T) with chemotherapy has been shown to improve survival in breast cancer patients but de novo resistance is common. Identifying predictors of response to T in primary cancers may lead to an understanding of mechanisms of resistance. We investigated whether combined microarray datasets from patients with early breast cancer treated with preoperative T and chemotherapy could predict for response to therapy. Methods: Two cohorts of patients with HER2 3+/FISH+, stage II-III breast cancer were included in this analysis: trial 1- T and docetaxel (n=38), trial 2 -T and vinorelbine (n=48), both for 12 weeks. Frozen tissue core biopsies were available and successfully amplified in 41 patients (trial 1: 20, trial 2: 21 patients), with standard sample processing, RNA extraction, amplification and hybridization to Affymetrix U133 chips. Differential expression of genes and chromosomal regions, (defined as >10 genes in a given chromosomal cytoband), between patients with pathologic complete response (pCR) vs. those with residual invasive disease were examined. A measure of total functional aneuploidy (tFA) was calculated by summing net deviation in expression of all chromosomal regions and a gene expression signature of genomic instability (CIN) was derived by the identification of genes showing a high level of correlation with tFA . Results: By unsupervised hierarchical analysis, both datasets interdigitated suggesting no inherent bias. Gene expression patterns of individual genes showed weak associations with pCR. However, distinct statistically significant chromosomal regions, Chr2p23 Chr6q24 Chr7q33 Chr2p2 Chr12q21.31 Chr14q32.2 Chr1p34.2 Chr8q21.3, were associated with pCR to T therapy (p<0.005), and were confirmed in more than 50% samples by SNP analysis. In addition, resistant tumors showed higher levels of the CIN signature (p<0.005). Conclusions: We have shown that gene expression data can be merged and used for discovery predictive chromosomal regions associated T response. In addition, chromosomal instability was associated with T resistance. If validated, these distinct dysregulated chromosomal regions may serve as predictive markers of response to trastuzumab therapy. [Table: see text]

Abstract
OBJECTIVE To evaluate the microsatellite instability (MIN) in gastric cancers (GC). METHODS MIN was examined in 106 cases of GC, using the radioactive polymerase chain reaction-based method. RESULTS The frequency of MIN was significantly higher in expanding type of GC as compared with the infiltrative type (P < 0.005, chi 2 test). No significant association with histologic type, pTNM stage, age and sex was found (P > 0.05, chi 2 test). CONCLUSIONS These findings reveal that MIN might be an important contributor to the development and progress of a significant number of GC, especially the expanding type which, as acknowledged traditionally, has a favorable prognosis.
