Abstract
Corneal diseases are prevalent eye conditions in China, and the lack of effective treatment in the short term can lead to blindness. However, delivering drugs to the cornea safely and effectively poses a significant challenge due to the presence of ocular barriers and clearance mechanisms. Conventional drug delivery methods exhibit low bioavailability, making it difficult to achieve therapeutic effects. Microneedles, with their ability to penetrate ocular surface barriers effectively, offer a low-invasive and highly promising drug delivery technology. This article introduces the main delivery barriers on the ocular surface, classifies microneedles, and highlights the latest developments in the treatment of corneal diseases. Finally, the potential challenges of applying microneedle delivery systems to the ocular surface are analyzed, aiming to provide insights for the clinical application of microneedles in corneal diseases.

Abstract
PURPOSE The Coexpression Extrapolation (COXEN) gene expression model with chemotherapy-specific scores [for methotrexate, vinblastine, adriamycin, cisplatin (ddMVAC) and gemcitabine/cisplatin (GC)] was developed to identify responders to neoadjuvant chemotherapy (NAC). We investigated RNA-based molecular subtypes as additional predictive biomarkers for NAC response, progression-free survival (PFS), and overall survival (OS) in patients treated in S1314. EXPERIMENTAL DESIGN A total of 237 patients were randomized between four cycles of ddMVAC (51%) and GC (49%). On the basis of Affymetrix transcriptomic data, we determined subtypes using three classifiers: TCGA (k = 5), Consensus (k = 6), and MD Anderson (MDA; k = 3) and assessed subtype association with path response to NAC and determined associations with COXEN. We also tested whether each classifier contributed additional predictive power when added to a model based on predefined stratification (strat) factors (PS 0 vs. 1; T2 vs. T3, T4a). RESULTS A total of 155 patients had gene expression results, received at least three of four cycles of NAC, and had pT-N response based on radical cystectomy. TCGA three-group classifier basal-squamous (BS)/neuronal, luminal (Lum), Lum infiltrated, and GC COXEN score yielded the largest AUCs for pT0 (0.59, P = 0.28; 0.60, P = 0.18, respectively). For downstaging ( CONCLUSIONS The Consensus classifier, based in part on the TCGA and MDA classifiers, modestly improved prediction for pathologic downstaging but subtypes were not associated with PFS or OS.

Abstract
PURPOSE/OBJECTIVE(S) Recent studies indicate that the novel lymphocyte-C-reactive protein ratio (LCR) is strongly associated with the survival of various tumors, but its prognostic value in nasopharyngeal carcinoma (NPC) is understudied. This study aimed to explore the relationship between the LCR and overall survival (OS) in NPC and to develop a predictive model. MATERIALS/METHODS A total of 841 NPC patients received concurrent chemoradiotherapy (CCRT) were retrospectively enrolled and randomly divided into training cohort (n = 589) and validation cohort (n = 252). Univariate and multivariate Cox analyses were performed to identify variables associated with OS and construct a predictive nomogram. The predictive accuracy of the nomogram was evaluated and independently validated. RESULTS The LCR score differentiated NPC patients into two groups with distinct prognoses (HR = 0.53; 95% CI: 0.32-0.89, P = 0.014). Multivariate analysis showed that age, T stage, N stage, EBV-DNA status, and LCR score were independently associated with OS and a predictive nomogram was developed. The nomogram had a good performance for the prediction of OS [C-index = 0.770 (95% CI: 0.675-0.864)] and outperformed the traditional staging system [C-index = 0.589 (95% CI: 0.385-0.792)]. The results were internally validated using an independent cohort. CONCLUSION The novel nutrition-inflammation marker of LCR could serve as a simplified, affordable, easy-to-obtain, non-invasive, and readily promotive prognostic marker for NPC patients received CCRT, and the LCR-based prognostic nomogram outperformed the conventional staging system in terms of predictive power.

Abstract
BACKGROUND The burden of influenza is mostly felt by employees and employers because of increased absenteeism rates, loss of productivity and associated direct costs. Even though interventions against influenza among working adults are effective, patronage and compliance to these measures especially vaccination are low compared to other risk groups. AIMS This study was aimed to assess evidence of economic evaluations of interventions against influenza virus infection among workers or in the workplace setting. METHODS The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) reporting guideline for systematic reviews was followed. Three databases, PubMed, Web of Science and EconLit, were searched using keywords to identify relevant articles from inception till 25 October 2020. Original peer-reviewed papers that conducted economic evaluations of influenza interventions using cost-benefit, cost-effectiveness or cost-utility analysis methods focused on working-age adults or work settings were eligible for inclusion. Two independent teams of co-authors extracted and synthesized data from identified studies. RESULTS Twenty-four articles were included: 21 were cost-benefit analyses and 3 examined cost-effectiveness analyses. Two papers also presented additional cost-utility analysis. Most of the studies were pharmaceutical interventions (n = 23) primarily focused on vaccination programs while one study was a non-pharmaceutical intervention examining the benefit of paid sick leave. All but two studies reported that interventions against influenza virus infection at the workplace were cost-saving and cost-effective regardless of the analytic approach. CONCLUSIONS Further cost-effectiveness research in non-pharmaceutical interventions against influenza in workplace settings is warranted. There is a need to develop standardized methods for reporting economic evaluation methods to ensure comparability and applicability of future research findings.

Abstract
Calf diarrhoea has been a major cause of economic losses in the global dairy industry. Many factors, including multiple pathogen infections, can directly or indirectly cause calf diarrhoea. This study compared the faecal virome between 15 healthy calves and 15 calves with diarrhoea. Significantly lower diversity of viruses was found in samples from animals with diarrhoea than those in the healthy ones, and this feature may also be related to the age of the calves. Viruses belonging to the families Astroviridae and Caliciviridae that may cause diarrhoea in dairy calves have been characterized, which revealed that reads of caliciviruses and astroviruses in diarrhoea calves were much higher than those in healthy calves. Five complete genomic sequences closely related to Smacoviridae have been identified, which may participate in the regulation of the gut virus community ecology of healthy hosts together with bacteriophages. This research provides a theoretical basis for further understanding of known or potential enteric pathogens related to calf diarrhoea.

Abstract
BACKGROUND There is no clinically applicable prognostic model designed for patients with de novo metastatic nasopharyngeal carcinoma (mNPC) treated with chemotherapy followed by locoregional radiotherapy (LRRT). We sought to develop a predictive tool of overall survival for individualized prediction and risk stratification in this heterogeneous patient population. PATIENTS AND METHODS A total of 244 eligible patients with de novo mNPC, who were treated with platinum-based first-line chemotherapy followed by LRRT, were included in this retrospective study. We divided patients into the training and validation sets based on the date of initial treatment, with 152 patients treated between 2008 and 2013 comprising the training set for model development and 92 patients treated at a later time (2014 to 2015) forming the validation set. We applied Cox proportional hazards model to examine factors associated with overall survival (OS). We developed and subsequently validated a prognostic model to predict OS. We assessed the performance of this prognostic model and stratified patients based on prognostic scores obtained from this proposed model. RESULTS The median OS of the entire cohort was 60.9 months. C-creative protein, number of metastatic sites, liver metastasis, post-treatment Epstein-Barr virus DNA, and response of metastasis were significantly associated with OS. A prognostic model for individual survival prediction was developed and graphically represented as a nomogram. The model showed favorable discrimination (C-index: 0.759), predictive accuracy [time dependent area under the curve (tAUC) at 5 years: 0.800], and calibration, and was further validated in an independent dataset. A risk stratification derived from the model can stratify these patients into three prognostic subgroups with significantly different survival. CONCLUSION We developed and validated a prognostic model that exhibited adequate performance in individualized prediction and risk stratification for patients with de novo mNPC treated with chemotherapy followed by LRRT.

Abstract
BACKGROUND Ticks are one of the most common external parasites in dogs, and are associated with the transmission of a number of major zoonoses, which result in serious harm to human health and even death. Also, the increasing number of pet dogs and pet owners in China has caused concern regarding human tick-borne illnesses. Accordingly, studies are needed to gain a complete understanding of the bacterial composition and diversity of the ticks that parasitize dogs. OBJECTIVES To date, there have been relatively few reports on the analysis of the bacterial community structure and diversity in ticks that parasitize dogs. The objective of this study was to investigate the microbial composition and diversity of parasitic ticks of dogs, and assessed the effect of tick sex and geographical region on the bacterial composition in two tick genera collected from dogs in China. METHODS A total of 178 whole ticks were subjected to a 16S ribosomal RNA (rRNA) next generation sequencing analysis. The Illumina MiSeq platform targeting the V3-V4 region of the 16S rRNA gene was used to characterize the bacterial communities of the collected ticks. Sequence analysis and taxonomic assignment were performed using QIIME 2 and the GreenGene database, respectively. After clustering the sequences into taxonomic units, the sequences were quality-filtered and rarefied. RESULTS After pooling 24 tick samples, we identified a total of 2,081 operational taxonomic units, which were assigned to 23 phyla and 328 genera, revealing a diverse bacterial community profile. The high, moderate and low prevalent taxa include 46, 101, and 182 genera, respectively. Among them, dominant taxa include environmental bacterial genera, such as Psychrobacter and Burkholderia. Additionally, some known tick-associated endosymbionts were also detected, including Coxiella, Rickettsia, and Ricketssiella. Also, the potentially pathogenic genera Staphylococcus and Pseudomonas were detected in the tick pools. Moreover, our preliminary study found that the differences in microbial communities are more dependent on the sampling location than tick sex in the tick specimens collected from dogs. CONCLUSIONS The findings of this study support the need for future research on the microbial population present in ticks collected from dogs in China.

Abstract
We investigate the impact of the photorefractive effect on lithium niobate integrated quantum photonic circuits dedicated to continuous variable on-chip experiments. The circuit main building blocks, i.e. cavities, directional couplers, and periodically poled nonlinear waveguides, are studied. This work demonstrates that photorefractivity, even when its effect is weaker than spatial mode hopping, might compromise the success of on-chip quantum photonics experiments. We describe in detail the characterization methods leading to the identification of this possible issue. We also study to which extent device heating represents a viable solution to counter this effect. We focus on photorefractive effect induced by light at 775 nm, in the context of the generation of non-classical light at 1550 nm telecom wavelength.

Abstract
AIMS To explore whether there is a different strength of association between self-rated health and all-cause mortality in people with type 2 diabetes across three country groupings: nine countries grouped together as 'established market economies'; Asia; and Eastern Europe. METHODS The ADVANCE trial and its post-trial follow-up were used in this study, which included 11 140 people with type 2 diabetes from 20 countries, with a median follow-up of 9.9 years. Self-rated health was reported on a 0-100 visual analogue scale. Cox proportional hazard models were fitted to estimate the relationship between the visual analogue scale score and all-cause mortality, controlling for a range of demographic and clinical risk factors. Interaction terms were used to assess whether the association between the visual analogue scale score and mortality varied across country groupings. RESULTS The visual analogue scale score had different strengths of association with mortality in the three country groupings. A 10-point increase in visual analogue scale score was associated with a 15% (95% CI 12-18) lower mortality hazard in the established market economies, a 25% (95% CI 21-28) lower hazard in Asia, and an 8% (95% CI 3-13) lower hazard in Eastern Europe. CONCLUSIONS Self-rated health appears to predict 10-year all-cause mortality for people with type 2 diabetes worldwide, but this relationship varies across groups of countries.

Abstract
OBJECTIVE Our study aimed to investigate the expression pattern, clinicopathological feature and prognostic role of miR-1181 in nasopharyngeal carcinoma (NPC), and to determine the functional effects and potential mechanism of miR-1181 in NPC. PATIENTS AND METHODS The expression levels of miR-1181 were determined in NPC tissues and cell lines by RT-PCR. The clinical data were interpreted by chi-square test, univariate analysis, and multivariate analysis. The effect of PVT1 on proliferation was evaluated by CCK-8 and colony formation assays, and migration and invasion ability were evaluated by transwell and wound-healing assays. The association between miR-1181 and Wnt/β-catenin pathway was analyzed by Western blot. RESULTS We found that miR-1181 expression was significantly down-regulated in both NPC tissues and cell lines. Low expression of miR-1181 was significantly associated with N stage (p=0.013), clinical stage (p=0.037) and grade (p=0.033). Clinical assays showed that patients with low miR-1181 expression had shorter overall survival time than those with high miR-1181 expression (p=0.0007). Multivariate analysis revealed that miR-1181 expression was independently associated with the overall survival. Functional investigations indicated that overexpression of miR-1181 suppressed NPC cells proliferation, migration and invasion. Mechanistically, forced miR-1181 expression suppressed the activity of Wnt/β-catenin pathway. CONCLUSIONS Our findings proved that miR-1181 may serve as a candidate prognostic biomarker and target for new therapies in NPC patients.

Abstract
Porcine sapelovirus A (PSV) is a single stranded, positive-sense, non-enveloped RNA virus that causes enteritis, pneumonia, polioencephalomyelitis, and reproductive disorders in pigs. Research on PSV infection and interaction with host cells is unclear. In this study, we applied tandem mass tag proteomics analysis to investigate the differentially expressed proteins (DEPs) in PSV-infected pig kidney (PK)-15 cells and explored the interactions between PSV and host cells. Here we mapped 181 DEPs, including 59 up-regulated and 122 down-regulated DEPs. Among them, osteopontin (SPP1), induced protein with tetratricopeptide repeats 5 (IFIT5), ISG15 ubiquitin-like modifier (ISG15), vinculin (VCL), and syndecan-1 (SDC1) were verified significantly changed using RT-qPCR. Additionally, overexpression of SDC1 promoted PSV viral protein (VP)1 synthesis and virus titer, and silencing of SDC1 revealed the opposite results. Our findings show that SDC1 is a novel host protein and plays crucial roles in regulating PSV replication.

Abstract
BACKGROUND Porcine sapelovirus (PSV), a species of the genus Sapelovirus within the family Picornaviridae, are a significant cause of enteritis, pneumonia, polioencephalomyelitis and reproductive disorders in pigs. However, the life cycle of PSV on the molecular level is largely unknown. METHODS Here, we used chemical inhibitors, RNA interference, and overexpression of dominant negative (DN) mutant plasmids to verify the roles of distinct endocytic pathways involved in PSV entry into porcine small intestinal epithelial cell line (IPEC-J2). RESULTS Our experiments indicated that PSV infection was inhibited when cells were pre-treated with NH4Cl or chloroquine. Inhibitors nystatin, methyl-β-cyclodextrin, dynasore and wortmannin dramatically reduced PSV entry efficiency, whereas the inhibitors chlorpromazine and EIPA had no effect. Furthermore, overexpression caveolin DN mutant and siRNA against caveolin also decreased virus titers and VP1 protein synthesis, whereas overexpression EPS15 DN mutant and siRNA against EPS15 did not reduce virus infection. CONCLUSIONS Our findings suggest that PSV entry into IPEC-J2 cells depends on caveolae/lipid raft mediated-endocytosis, that is pH-dependent and requires dynamin and PI3K but is independent of clathrin and macropinocytosis.

Abstract
To comprehensively understand the endocytosis of Sapelovirus A (PSV) entry into PK-15 cells, we studied PSV infection in the context of cell perturbations through drug inhibition, siRNA silencing and overexpression of dominant negative (DN) mutants. We showed here that PSV infection of PK-15 cells was unaffected by pretreated with chlorpromazine, EIPA, knockdown of the clathrin heavy chain or overexpression of Eps15 DN mutant. Conversely, PSV infection was sensitive to NH4Cl, chloroquine, dynasore, nystatin, MβCD and wortmannin with reduced PSV VP1 expression levels and virus titer. Additionally, PSV invasion leaded to rapid actin rearrangement and disruption of the cellular actin network enhanced PSV infection. After internalization the virus was transported to late endosomes and/or cycling endosomes that requires the participation of Rab7 and Rab11. Our findings demonstrate that PSV uses caveolae-dependent endocytosis as the predominant entry portal into PK-15 cells which requires low pH, dynamin, Rab7 and Rab11.

Abstract
OBJECTIVES The mcr-1 gene is the first reported plasmid-mediated colistin resistance gene. It has caused worldwide concern about the colistin resistance in Gram-negative bacteria. The aim of this research was to study the impact of mcr-1 on the selection of high-level colistin resistance (HLCR) mutations in Escherichia coli and Klebsiella pneumoniae. METHODS We detected the HLCR mutation rates of Enterobacteriaceae strains (K. pneumoniae XH209, KP10, and E. coli Q3, ATCC 25922) and their transformants harbouring the mcr-1 gene. Further analysis of the HLCR mutants was conducted by sequencing, plasmid elimination experiment, and real-time quantitative PCR. RESULTS For XH209, mean mutation rate of XH209-pMCR was 1.7 (95% confidence interval (CI) 0.76-2.54) × 10-8, while XH209 and XH209-pCR2.1 showed mutation rates of 2.0 (95% CI, 1.32-2.67) × 10-8 and 2.3 (95% CI 1.47-3.13) × 10-8. For KP10 and its derived strains KP10-pCR2.1, KP10-pMCR, the mutation rates were 3.5 (95% CI 0.77-6.13) × 10-8, 4.8 (95% CI 0.69-8.94) × 10-8 and 4.2 (95% CI 0.95-7.54) × 10-8 respectively. The mutation rates of E. coli strains Q3-pMCR and ATCC25922-pMCR were 3.4 (95% CI 0.19-7.47) × 10-8 and 1.54 (95% CI 0.27-2.8) × 10-9, which were significantly higher than their corresponding non-mcr-1-carrying strains (p < 0.05). CONCLUSIONS Beside the knowledge that mcr-1 mediates low-level colistin resistance, this gene also facilitates selection of HLCR mutants in E. coli, but does not affect K. pneumoniae.

Abstract
Bartonella effector proteins (named Beps) are substrates of VirB type IV secretion system for translocation into host cells evolved in Bartonella spp. Among these, BepE has been shown to protect cells from fragmentation effects triggered by other Beps and to promote in vivo dissemination of bacteria from the dermal site of inoculation to the bloodstream. Bacterial pathogens secreted effectors to modulate the interplay with host autophagy, either to combat autophagy to escape its bactericidal effect or to exploit autophagy to benefit intracellular replication. Here, we reported a distinct phenotype that selective autophagy in host cells is activated as a countermeasure, to attack BepE via conjugation with K63 polyubiquitin chain on BepE. We found that ectopic expression of Bartonella quintana BepE specifically induced punctate structures that colocalised with an autophagy marker (LC3-II) in host cells, in addition to filopodia and membrane ruffle formation. Two tandemly arranged Bartonella Intracellular Delivery (BID) domains in the BepE C-terminus, where ubiquitination of sister pairs of lysine residues was confirmed, were essential to activate host cell autophagy. Multiple polyubiquitin chain linkages of K27, K29, K33, and K63 were found to be conjugated at sites of K222 and K365 on BepE, of which K63 polyubiquitination on BepE K365 determined the selective autophagy (p62/SQSTM1 positive autophagy) independent of the PI3K pathway. Colocalisation of BepE with LAMP1 confirmed the maturation of BepE-induced autophagosomes in which BepE were targeted for degradation. Moreover, host cells employed selective autophagy to counter-attack BepE to rescue cells from BepE-induced endocytosis deficiency.

Abstract
Pigs share many anatomical and physiological features with humans, offering a unique and viable model for biomedical research. Although porcine female germline stem cells (FGSCs) were identified in the juvenile ovary, no reports described the isolation and purification of FGSCs from the pig at sexual maturity. Here, we isolated, purified, and cultured FGSCs from porcine ovaries at sexual maturity. Furthermore, we established and characterized the porcine FGSC (pFGSC) lines. In addition, we found that pFGSC lines could differentiate into oocytes when injection into tissue grafts, including human ovarian tissues. The results show that FGSCs exist in ovaries of Banna mini-pigs at juvenile and sexually maturity. These findings have implications in animal biotechnology applications and regeneration medicine.

Abstract
To explore the diagnostic value of copeptin (CPP) in cardiorenal syndrome (CRS) in rats and the association between CPP and impairment of heart and kidney, 60 male SD rats were randomly divided into blank control group (CK group), kidney failure group (SNX group), heart failure group (MI group), and CRS group. Heart and kidney function and their histology changes in rats from each group were detected. The correlation between serum CPP and heart and kidney function indexes was performed with Pearson correlation analysis. The HE staining of heart and kidney showed that the tissue lesion was more severe in CRS group than in SNX group and MI group. There was a significant positive correlation between serum CPP and brain natriuretic peptide (BNP) (r=0.638, P<0.05). No correlation was observed between serum CPP and cardiac function index (left ventricular systolic pressure, left ventricular diastolic pressure, left ventricular end-diastolic pressure) or renal function index (serum creatinine, urine creatinine, blood urea nitrogen) (r=0.512, 0.189,-0.063, 0.207, 0.290, 0.595, respectively, all P>0.05). The CPP level is associated with the degree of heart and kidney damage in CRS rats.

Abstract
BACKGROUND Porcine teschoviruses (PTVs) are small non-enveloped viruses with single-stranded, positive sense genomic RNA, belonging to the family Picornaviridae. Natural infections of teschoviruses are limited to pigs. RESULTS In this study, a PTV HuN-1 was found that it could be proliferated in PK-15 cell, and it came from the pig fecal samples from Hunan province, in central China. The complete genome of the HuN-1 was amplified by RT-PCR and sequenced. The complete genome of HuN-1 isolate is 7098 nt, which shares the highest sequence identity (85.9%) with the PTV 8 strain of Jilin/2003/2 and Fuyu/2009/2. The HuN-1 isolate contains only one ORF (from 320 to 7039 nt) coding a 2240 amino acid polyprotein. Aligned sequences show that more mutations occurred in the structural region than in the nonstructural region. Phylogenetic analysis showed that HuN-1 isolate did not clustered with the hitherto reported strains, according to P1 sequences, forming a subgroup in the PTV cluster. CONCLUSION In this study, complete genome of PTV HuN-1 was cloned and sequenced. Detection and characterization of further PTV strains from different geographic areas are important to understand the worldwide distribution and heterogeneity (serotype) of PTVs and their association with symptomatic infections in pigs.

Abstract
Background Free-range cattle are common in the Northeast China area, which have close contact with farmers and may carry virus threatening to cattle and farmers. Methods Using viral metagenomics we analyzed the virome in plasma samples collected from 80 cattle from the forested region of Northeast China. Results The virome of cattle plasma is composed of the viruses belonging to the families including Parvoviridae, Papillomaviridae, Picobirnaviridae, and divergent viral genomes showing sequence similarity to circular Rep-encoding single stranded (CRESS) DNA viruses. Five such CRESS-DNA genomes were full characterized, with Rep sequences related to circovirus and gemycircularvirus. Three bovine parvoviruses belonging to two different genera were also characterized. Conclusion The virome in plasma samples of cattle from the forested region of Northeast China was revealed, which further characterized the diversity of viruses in cattle plasma.

Abstract
Pigs share many anatomical and physiological features with humans, offering a unique and viable model for biomedical research. Tandem mass tag method followed by mass spectrometry analysis was utilized to identify peptides (47,405), proteins (14,701), and protein groups (7634) in ovaries of 8- and 32-week-old postnatal Banna miniature pigs. After annotation and analysis by Kyoto Encyclopedia of Genes and Genomes pathway and Gene Ontology, the proteins were identified as being involved in hormone metabolic pathways and maintenance, proliferation, and regulation of stem cells. In addition, we found 638 differentially expressed proteins between ovaries of 8- and 32-week-old postnatal Banna miniature pigs. We used Interactive Pathway Explorer to produce an overview of pig ovarian proteomics. Compared with those of the 8-week-old group, the proteins enriched in metabolism of steroid hormones, metabolism of lipids, and energy metabolism pathway were upregulated in the 32-week-old group, indicating physiological characteristics of sexual maturity. These findings have implications in applications of biomedicine.

Abstract
In donor hearts from mini pigs, overtime cold preservation and ischemia-reperfusion injury cause poor graft quality and impaired heart function. Blockage of complement, apoptosis, and inflammation is considered a strategy for attenuating ischemia-reperfusion injury and protecting cardiac function. Minipig donor hearts were perfused and preserved in Celsior solution or transfection reagent containing Celsior solution with scramble siRNA or siRNAs targeting complement 3, caspase-8, caspase-3, and nuclear factor κB-p65 genes at 4°C and subsequently hemo-reperfused ex vivo (38°C) or transplanted into recipients. The protective effect of the siRNA solution was evaluated by measuring cell apoptosis, structural alteration, protein markers for tissue damage and oxidative stress, and cardiac function. We found a reduction in cell apoptosis, myocardial damage, and tissue inflammation by reduced biochemistry and markers and protein expression of proinflammatory cytokines and improvement in cardiac function, as shown by the improved hemodynamic indices in 12-hr-preserved siRNA-treated hearts of both ex vivo and orthotopic transplantation models. These findings demonstrate that blockade of inflammation and apoptosis pathways using siRNA can prolong cold preservation time and better protect donor heart function in cardiac transplantation of large animals, which may be beneficial for human heart preservation.

Abstract
Molecular phylogenies are increasingly being used to investigate the patterns and mechanisms of macroevolution. In particular, node heights in a phylogeny can be used to detect changes in rates of diversification over time. Such analyses rest on the assumption that node heights in a phylogeny represent the timing of diversification events, which in turn rests on the assumption that evolutionary time can be accurately predicted from DNA sequence divergence. But there are many influences on the rate of molecular evolution, which might also influence node heights in molecular phylogenies, and thus affect estimates of diversification rate. In particular, a growing number of studies have revealed an association between the net diversification rate estimated from phylogenies and the rate of molecular evolution. Such an association might, by influencing the relative position of node heights, systematically bias estimates of diversification time. We simulated the evolution of DNA sequences under several scenarios where rates of diversification and molecular evolution vary through time, including models where diversification and molecular evolutionary rates are linked. We show that commonly used methods, including metric-based, likelihood and Bayesian approaches, can have a low power to identify changes in diversification rate when molecular substitution rates vary. Furthermore, the association between the rates of speciation and molecular evolution rate can cause the signature of a slowdown or speedup in speciation rates to be lost or misidentified. These results suggest that the multiple sources of variation in molecular evolutionary rates need to be considered when inferring macroevolutionary processes from phylogenies.

Abstract
BACKGROUND The giant panda (Ailuropoda melanoleuca) is a vulnerable mammal herbivore living wild in central China. Viral infections have become a potential threat to the health of these endangered animals, but limited information related to these infections is available. METHODS Using a viral metagenomic approach, we surveyed viruses in the feces, nasopharyngeal secretions, blood, and different tissues from a wild giant panda that died from an unknown disease, a healthy wild giant panda, and 46 healthy captive animals. RESULTS The previously uncharacterized complete or near complete genomes of four viruses from three genera in Papillomaviridae family, six viruses in a proposed new Picornaviridae genus (Aimelvirus), two unclassified viruses related to posaviruses in Picornavirales order, 19 anelloviruses in four different clades of Anelloviridae family, four putative circoviruses, and 15 viruses belonging to the recently described Genomoviridae family were sequenced. Reflecting the diet of giant pandas, numerous insect virus sequences related to the families Iflaviridae, Dicistroviridae, Iridoviridae, Baculoviridae, Polydnaviridae, and subfamily Densovirinae and plant viruses sequences related to the families Tombusviridae, Partitiviridae, Secoviridae, Geminiviridae, Luteoviridae, Virgaviridae, and Rhabdoviridae; genus Umbravirus, Alphaflexiviridae, and Phycodnaviridae were also detected in fecal samples. A small number of insect virus sequences were also detected in the nasopharyngeal secretions of healthy giant pandas and lung tissues from the dead wild giant panda. Although the viral families present in the sick giant panda were also detected in the healthy ones, a higher proportion of papillomaviruses, picornaviruses, and anelloviruses reads were detected in the diseased panda. CONCLUSION This viral survey increases our understanding of eukaryotic viruses in giant pandas and provides a baseline for comparison to viruses detected in future infectious disease outbreaks. The similar viral families detected in sick and healthy giant pandas indicate that these viruses result in commensal infections in most immuno-competent animals.

Abstract
The hallmark of Bartonella infection is long-lasting intraerythrocytic parasitism. However, the process of Bartonella bacteremia is still enigmatic. In the current study, we used Bartonella tribocorum to determine how Bartonella invasion into the bloodstream from dermal inoculation might occur. Bartonella was poorly phagocytized by peritoneal macrophages in vitro. Intracellular Bartonella survived and replicated in macrophages at an early stage of infection. Intracellular Bartonella inhibited spontaneous cell death of macrophages. They also inhibited Salmonella-induced pyroptosis and mildly reduced inflammasome activation through an unidentified mechanism. A rat model confirmed that Bartonella was also inadequately phagocytized in vivo, because numerous free-floating bacilli were observed in lymph collected from thoracic duct drainage as early as 2 hours after inoculation. Lymphatic fluid drainage in the bloodstream significantly reduced the bacterial load in the bloodstream. These findings illustrated a potential route by which Bartonella invade bloodstream from dermal inoculation before they are competent to infect erythrocytes.

Abstract
Background Sapovirus (SaV), a member of the family Caliciviridae, is an etiologic agent of gastroenteritis in humans and pigs. To date, both intra- and inter-genogroup recombinant strains have been reported in many countries except for China. Here, we report an intra-genogroup recombination of porcine SaV identified from a piglet with diarrhea of China. Methods A fecal sample from a 15-day-old piglet with diarrhea was collected from Shanghai, China. Common agents of gastroenteritis including porcine circovirus type 2, porcine rotavirus, porcine transmissible gastroenteritis virus, porcine SaV, porcine norovirus, and porcine epidemic diarrhea virus were detected by RT-PCR or PCR method. The complete genome of porcine SaV was then determined by RT-PCR method. Phylogenetic analyses based on the structural region and nonstructural (NS) region were carried out to group this SaV strain, and it was divided into different genotypes based on these two regions. Recombination analysis based on the genomic sequence was further performed to confirm this recombinant event and locate the breakpoint. Results All of the agents showed negative results except for SaV. Analysis of the complete genome sequence showed that this strain was 7387 nt long with two ORFs and belonged to SaV GIII. Phylogenetic analyses of the structural region (complete VP1 nucleotide sequences) grouped this strain into GIII-3, whereas of the nonstructural region (RdRp nucleotide sequences) grouped this strain into GIII-2. Recombination analysis based on the genomic sequence confirmed this recombinant event and identified two parental strains that were JJ259 (KT922089, GIII-2) and CH430 (KF204570, GIII-3). The breakpoint located at position 5139 nt of the genome (RdRp-capsid junction region). Etiologic analysis showed the fecal sample was negative with the common agents of gastroenteritis, except for porcine SaV, which suggested that this recombinant strain might lead to this piglet diarrhea. Conclusions P2 strain was an intra-genogroup recombinant porcine SaV. To the best of our knowledge, this study would be the first report that intra-genogroup recombination of porcine SaV infection was identified in pig herd in China.

Abstract
Abstract
Multivitamin use has been related to a modest reduced risk of colorectal cancer (CRC), but evidence on its use after diagnosis in relation to survival has been limited. Incident, invasive CRC cases were identified through cancer registries from 1997–2008 and enrolled in four population-based sites of the Colon Cancer Family Registry (Fred Hutchinson Cancer Research Center, Cancer Care Ontario, Mayo Clinic, and the Universities of Queensland and Melbourne). At enrollment, a standardized interview ascertained multivitamin use in the year prior to diagnosis. A follow-up questionnaire was administered approximately 5 years after baseline, with 2,586 participants providing information on their multivitamin use at both time points. Survival outcomes were identified through linkage to national death registries. Delayed-entry Cox regression was used to estimate the association between patterns of multivitamin use and overall or CRC-specific survival (Hazard Ratio (HR) and 95% Confidence Interval (CI)), with survival time beginning at the 5-year follow-up survey. Models were adjusted for age at diagnosis, sex, body mass index, smoking history, stage, study center, and number of days from diagnosis to baseline survey. Over a median 4.8 years after the follow-up survey, 397 participants died (103 from CRC). Multivitamin use was common: at the 5-year follow-up, 37% reported continued use since before diagnosis, 12% had initiated use, 17% had discontinued use, and only 34% participants reported never using multivitamins. Compared to never use of multivitamins, continued use was significantly associated with increased subsequent overall survival (HR = 0.71, 95% CI: 0.55–0.91). However, this association did not reach statistical significance for CRC-specific survival (HR = 0.76, 95% CI: 0.47–1.24). No significant association was observed for discontinuing (HR = 0.92, 95% CI: 0.68–1.25) or initiating (HR = 0.80, 95% CI: 0.55–1.13) multivitamin use from baseline to follow-up, compared to never users, though initiating use trended towards increased survival. These findings suggest that continuing multivitamin use after a CRC diagnosis may increase survival; replication and details on the specific micronutrients included are needed.

Abstract
Zfp462 is a newly identified vertebrate-specific zinc finger protein that contains nearly 2500 amino acids and 23 putative C2H2-type zinc finger domains. So far, the functions of Zfp462 remain unclear. In our study, we showed that Zfp462 is expressed predominantly in the developing brain, especially in the cerebral cortex and hippocampus regions from embryonic day 7.5 to early postnatal stage. By using a piggyBac transposon-generated Zfp462 knockout (KO) mouse model, we found that Zfp462 KO mice exhibited prenatal lethality with normal neural tube patterning, whereas heterozygous (Het) Zfp462 KO (Zfp462+/- ) mice showed developmental delay with low body weight and brain weight. Behavioral studies showed that Zfp462+/- mice presented anxiety-like behaviors with excessive self-grooming and hair loss, which were similar to the pathological grooming behaviors in Hoxb8 KO mice. Further analysis of grooming microstructure showed the impairment of grooming patterning in Zfp462+/- mice. In addition, the mRNA levels of Pbx1 (pre-B-cell leukemia homeobox 1, an interacting protein of Zfp462) and Hoxb8 decreased in the brains of Zfp462+/- mice, which may be the cause of anxiety-like behaviors. Finally, imipramine, a widely used and effective anti-anxiety medicine, rescued anxiety-like behaviors and excessive self-grooming in Zfp462+/- mice. In conclusion, Zfp462 deficiency causes anxiety-like behaviors with excessive self-grooming in mice. This provides a novel genetic mouse model for anxiety disorders and a useful tool to determine potential therapeutic targets for anxiety disorders and screen anti-anxiety drugs.
