Abstract
A 37-year-old woman with a history of inflammatory bowel disease on mercaptopurine presented with a week of recurrent fever, headache, myalgias and mildly elevated serum transaminases and leucopenia. Her workup revealed primary cytomegalovirus (CMV) infection with atypical lymphocytosis, elevated viral load, positive IgM and negative IgG. Two weeks after her initial presentation, she developed odynophagia and diarrhoea prompting endoscopic evaluation with biopsies, which demonstrated CMV disease of the gastrointestinal tract. Her fever and systemic symptoms improved rapidly with initiation of intravenous ganciclovir. She was transitioned to and maintained on oral valganciclovir until two and half months after discharge when her symptoms and lab abnormalities had fully subsided.

Abstract
AIM To discuss the effects and mechanism of microRNA-34a in cell apoptosis induced by osteoarthritis. METHODS Collection of the normal and osteoarthritis synovial tissues and measurements of the miRNA-34a and TGIF2 gene expression. In the cell experiment, the cells were divided into Control, Blank and miRNA inhibitor group. The cell proliferation and apoptosis of the different groups were measured by MTT and flow cytometry and the TGIF2 protein expression in the different groups was evaluated by WB assay. The correlation between TGIF2 and miRNA-34a was analyzed by Double luciferase experiment. RESULTS Compared with normal synovial tissues, the miRNA-34a gene expression was significantly up-regulated and TGIF2 gene expression was significantly suppressed in osteoarthritis synovial tissues (p < 0.001, respectively). The cell proliferation was significantly depressed and the cell apoptosis rate was significantly increased in miRNA inhibitor group compared with the Control group (p < 0.001, respectively). Using the WB assay it was shown that the TGIF2 protein expression of miRNA inhibitor group was significantly suppressed compared with that of Control group (p < 0.01). By Double luciferase assay, TGIF2 gene was one target gene of miRNA-34a. CONCLUSION miRNA-34a could induce osteoarthritis synovial cell apoptosis via regulation of TGIF2 in vitro (Fig. 6, Ref. 29).

Abstract
Trogocytosis, intercellular cannibalism distinct from phagocytosis, occurs when cells rearrange during development. Here, Gong et al. reveal that trogocytosis induced by ephrins and Eph receptors involves phagocytic adaptor protein Gulp1, Rac-specific guanine nucleotide exchange factor Tiam2, and endocytic GTPase dynamin. These results suggest that ephrin/Eph-induced trogocytosis uses phagocytosis-like mechanisms. Trogocytosis, in which cells nibble away parts of neighboring cells, is an intercellular cannibalism process conserved from protozoa to mammals. Its underlying molecular mechanisms are not well understood and are likely distinct from phagocytosis, a process that clears entire cells. Bi-directional contact repulsion induced by Eph/ephrin signaling involves transfer of membrane patches and full-length Eph/ephrin protein complexes between opposing cells, resembling trogocytosis. Here, we show that the phagocytic adaptor protein Gulp1 regulates EphB/ephrinB trogocytosis to achieve efficient cell rearrangements of cultured cells and during embryonic development. Gulp1 mediates trogocytosis bi-directionally by dynamic engagement with EphB/ephrinB protein clusters in cooperation with the Rac-specific guanine nucleotide exchange factor Tiam2. Ultimately, Gulp1’s presence at the Eph/ephrin cluster is a prerequisite for recruiting the endocytic GTPase dynamin. These results suggest that EphB/ephrinB trogocytosis, unlike other trogocytosis events, uses a phagocytosis-like mechanism to achieve efficient membrane scission and engulfment.

Abstract
Elucidation of the pig microRNAome is essential for interpreting functional elements of the genome and understanding the genetic architecture of complex traits. Here, we extracted small RNAs from skeletal muscle and adipose tissue, and we compared their expression levels between one Western breed (Yorkshire) and seven indigenous Chinese breeds. We detected the expression of 172 known porcine microRNAs (miRNAs) and 181 novel miRNAs. Differential expression analysis found 92 and 12 differentially expressed miRNAs in adipose and muscle tissue respectively. We found that different Chinese breeds shared common directional miRNA expression changes compared to Yorkshire pigs. Some miRNAs differentially expressed across multiple Chinese breeds, including ssc-miR-129-5p, ssc-miR-30 and ssc-miR-150, are involved in adipose tissue function. Functional enrichment analysis revealed that the target genes of the differentially expressed miRNAs are associated mainly with signaling pathways rather than metabolic and biosynthetic processes. The miRNA-target gene and miRNA-phenotypic traits networks identified many hub miRNAs that regulate a large number of target genes or phenotypic traits. Specifically, we found that intramuscular fat content is regulated by the greatest number of miRNAs in muscle tissue. This study provides valuable new candidate miRNAs that will aid in the improvement of meat quality and production.

Abstract
PURPOSE Little is known about how a breast cancer diagnosis and treatment affects job-related outcomes in young women with breast cancer, who are an integral part of the workforce. We sought to describe employment trends among young breast cancer survivors. METHODS 911 women with non-metastatic breast cancer were surveyed about employment-related outcomes 1 year post-diagnosis. Participants were enrolled in the Young Women's Breast Cancer Study an ongoing, multi-center cohort of women diagnosed with breast cancer at age ≤ 40. RESULTS Among 911 women, median age at diagnosis was 36 years (range 17-40). Most women (80%, n = 729) were employed 1 year post-diagnosis. Among the 7% (n = 62) employed before diagnosis but who reported unemployment at 1 year, approximately half reported they were unemployed for health reasons. Among employed women, 7% said treatment affected their ability to perform their job. Women with stage-three disease (vs. stage 1 disease, odds ratio (OR): 3.73, 95% CI 1.39-9.97) and those who reported having money to pay bills after cutting back or difficulty paying bills at baseline (vs. having enough money for special things, OR 2.70, 95% CI 1.32-5.52) at baseline were more likely to have transitioned out of the workforce. CONCLUSIONS Our results suggest an impact of disease burden and socioeconomic status on employment in young breast cancer survivors. There is a need to ensure young survivors who leave the workforce following diagnosis are sufficiently supported given the potential adverse psychosocial and financial impacts of unemployment on survivors, their families, communities, and society.

Abstract
11576 Background: Androgen deprivation therapy (ADT) plays a pivotal role in management of prostate cancer (PC), with prolonged ADT favored over short-term use in the definitive treatment of high risk PC with radiation. Objectives: To compare cardiorespiratory fitness (CRF) and cardiovascular (CV) mortality among patients with PC with and without ADT exposure, and to explore how duration of ADT exposure influences CRF and CV mortality risk. Methods: This is a retrospective study of patients referred for exercise treadmill testing (ETT) after a diagnosis of PC. PC risk classification was based on Gleason score (GS) at diagnosis: high risk GS ≥ 8, intermediate risk GS= 7, and low risk GS ≤ 6. CRF was categorized according to metabolic equivalents (METs): METs ≥ 8 defined as good CRF and METs < 8 as reduced CRF. ADT exposure was grouped as short-term (≤ 6 months) versus prolonged (> 6 months). Results: 616 patients underwent an ETT a median of 4.8 years (interquartile range: 2.0-7.9) after diagnosis of PC. 150 patients (24.3%) received ADT prior to ETT; 51 with short-term versus 99 with prolonged exposure. 524 (85.1%) patients had ≥ 2 CV risk factors, and 28 CV deaths occurred over 4.2 (interquartile range: 2.3-7.1) years following the ETT. Reduced CRF was more frequent among ADT-exposed versus ADT-naive patients (48.7 versus 32.6%, p< 0.001). Prolonged ADT was associated with reduced CRF (odds ratio (OR): 2.71; 95% confidence interval (CI): 1.31-5.61; p=0.007) and increased CV mortality (hazard ratio (HR): 3.87; 95% CI: 1.16-12.96; p=0.03) in adjusted analyses. In contrast, short-term ADT exposure was not independently associated with either reduced CRF (OR 1.71; 95% CI: 1.00-2.94); p=0.05) or CV mortality (HR: 1.60; 95% CI: 0.51-5.01; p=0.42). Conclusions: Among patients with PC and high baseline CV risk, > 6 months ADT exposure but not less was associated with reduced CRF and increased CV mortality. Reduced CRF may in part mediate increased CV mortality risk. Exercise interventions concurrent with prolonged ADT warrants investigation to potentially offset risk.

Abstract
AIM Sarcopenia is a robust prognostic indicator of outcomes after surgery for colorectal cancer (CRC). However, there are no serum markers routinely available for estimating skeletal muscle mass (SMM). The present study aimed to describe a new sarcopenia index (SI), serum creatinine (Scr) × cystatin C-based glomerular filtration rate, and investigate its association with short-term complications after curative resection of CRC. METHOD Consecutive patients who underwent curative resection of CRC from December 2011 to January 2017 were retrospectively identified. Skeletal muscle cross-sectional area was analysed on L3 computed tomographic images. Receiver operating characteristic curve analysis showed that the cutoff points of SI for sarcopenia were below 56.1 in men and below 43.7 in women. Patients were classified into low and high SI groups in accordance with these cutoff values. The association between SI and body composition and the impact of preoperative SI on postoperative outcomes were analysed. RESULTS Among 417 patients, SI showed a stronger correlation with skeletal muscle area (SMA) (r = 0.537, P < 0.001) than with the Scr/cystatin C ratio (r = 0.469, P < 0.001) and Scr (r = 0.447, P < 0.001). The low SI group had a lower SMA, lower preoperative haemoglobin, a higher prevalence of sarcopenia and experienced more postoperative complications compared with the high SI group (all P < 0.001). Multivariate logistic regression analysis showed that the independent risk factors for overall complications were low preoperative haemoglobin, low SI, sarcopenia and American Society of Anesthesiologists grade ≥ 3. CONCLUSION This new SI is a simple and useful surrogate marker for estimating SMM, and is associated with outcomes after CRC surgery.

Abstract
Objective: This study aimed to assess the prevalence and factors associated with pelvic organ prolapse (POP) in a representative sample of Chinese urban women. Methods: A total of 29613 Chinese urban women were recruited to this cross-sectional study between February 2014 and March 2016. The prevalence of POP, defined as any stage Ⅱ or higher POP resulting in symptoms, was assessed using questionnaires and physical examinations. Multivariable logistic regression was used to assess factors associated with POP. Results: 2 864 of 29 613 women (9.67%) had POP. The prevalence of POP increased with age ranging from 1.23% (82/6 646) of women aged between 20 and 29 years to 26.11% (727/2 784) for those aged 70 years or older (P<0.000 1). Overweight and obese women were more likely to have POP than normal weight women [AOR=1.56, 95%CI 1.42-1.72 vs AOR=1.74, 95%CI 1.48-2.03]. In the multivariate analysis, the independent risk factors were cough (AOR=1.70, 95%CI 1.44-2.02), constipation (AOR=2.05, 95%CI 1.82-2.32), physical disease (AOR=1.27, 95%CI 1.15-1.41), and gynecological diseases (AOR=2.08, 95%CI 1.89-2.29). Nulliparous (AOR=0.12, 95%CI 0.06-0.22) and caesarean section (CS) (AOR=0.55, 95%CI 0.47-0.64) were protective factors for POP. Conclusions: POP affects nearly 10% of women in Chinese urban region. The prevalence of POP increases significantly with age. The independent risk factors for POP are body mass index, cough, constipation, physical disease and gynecological diseases. Nulliparous and CS are protective factors for POP.

Abstract
Background MYC is a well-established cancer driver gene regulating the expression of numerous genes, indicating that polymorphisms in MYC response elements could affect tumorigenesis through altering MYC regulation. We performed integrative multistage study to evaluate the effects of variants in MYC response elements and colorectal cancer (CRC) risk. Patients and methods We systematically integrated ChIP-Seq, DNase-Seq and transcription factor motif data to screen variants with potential ability to affect the MYC binding affinity. Then, we conducted a two-stage case-control study, totally consisting of 4830 CRC cases and 4759 controls in Chinese population to identify risk polymorphisms and interactions. The effects of risk variants were confirmed by functional assays in CRC LoVo, SW480 and HCT15 cells. Results We identified a novel polymorphism rs11777210 in KBTBD11 significantly associated with CRC susceptibility (P = 2.43 × 10-12). Notably, we observed a significant interaction between rs11777210 and MYC nearby rs6983267 (P-multi = 0.003, P-add = 0.005), subjects carrying rs6983267 GG and rs11777210 CC genotypes showing higher susceptibility to CRC (2.83-fold) than those carrying rs6983267 TT and rs11777210 TT genotypes. We further demonstrated that rs6983267 T > G increased MYC expression, and MYC bound to and negatively regulated KBTBD11 expression when the rs11777210 C risk allele was present. KBTBD11 was downregulated in tumor tissues, and KBTBD11 knockdown promoted cell proliferation and inhibited cell apoptosis. Conclusion The rs11777210 is a potential predictive biomarker of CRC susceptibility, and KBTBD11 functions as a putative tumor suppressor in tumorigenesis. Our study highlighted the high CRC risk of people carrying rs6983267 G and rs11777210 C alleles, and provided possible biological mechanism of the interaction.

Abstract
Precision results on cosmic-ray electrons are presented in the energy range from 0.5 GeV to 1.4 TeV based on 28.1×10^{6} electrons collected by the Alpha Magnetic Spectrometer on the International Space Station. In the entire energy range the electron and positron spectra have distinctly different magnitudes and energy dependences. The electron flux exhibits a significant excess starting from 42.1_{-5.2}^{+5.4} GeV compared to the lower energy trends, but the nature of this excess is different from the positron flux excess above 25.2±1.8 GeV. Contrary to the positron flux, which has an exponential energy cutoff of 810_{-180}^{+310} GeV, at the 5σ level the electron flux does not have an energy cutoff below 1.9 TeV. In the entire energy range the electron flux is well described by the sum of two power law components. The different behavior of the cosmic-ray electrons and positrons measured by the Alpha Magnetic Spectrometer is clear evidence that most high energy electrons originate from different sources than high energy positrons.

Abstract
AIM To find potential predictors at unenhanced computed tomography (CT) to evaluate the stone clearance rate (SCR) of pancreatic duct stones (PDS) by extracorporeal shock wave lithotripsy (ESWL). MATERIALS AND METHODS A total of 106 consecutive patients with multiple stones of maximal transverse length (MTL) 0.3-3.6 cm in pancreatic head region were enrolled. Unenhanced CT was performed both before and after ESWL therapy. All patients underwent ESWL therapy using an electromagnetic lithotripter, and were divided into three groups with threshold values of >90%, 50-90% and <50% of SCR. Factors including sex, age, MTL, mean stone density (MSD), standard deviation of stone density (SDSD), variation coefficient of stone density (VCSD), attenuation density (AD), pancreatic duct diameter (PDD), skin-to-stone distance (SSD), and number of ESWL sessions were analysed, and their impact on SCR was evaluated by univariate and multivariate analyses. The diagnostic threshold of the independent predicting index was further calculated, and its relationship with SCR and ESWL was analysed by drawing a trend line. RESULTS The only significant predictor of SCR by ESWL was MSD (p<0.05). More courses of ESWL therapy are required in PDS patients with an MSD higher than the cut-off value of 375.4 HU (mean, 2.6 versus 1.8), but with a relatively lower SCR (mean, 43.96 versus 88.68%) . CONCLUSION MSD on pre-treatment unenhanced CT is an independent predictor for SCR of PDS patients treated with ESWL. Using a cut-off value of 375.4 HU, patients with low MSD are good candidates for ESWL therapy.

Abstract
Precision measurements of cosmic ray positrons are presented up to 1 TeV based on 1.9 million positrons collected by the Alpha Magnetic Spectrometer on the International Space Station. The positron flux exhibits complex energy dependence. Its distinctive properties are (a) a significant excess starting from 25.2±1.8 GeV compared to the lower-energy, power-law trend, (b) a sharp dropoff above 284_{-64}^{+91} GeV, (c) in the entire energy range the positron flux is well described by the sum of a term associated with the positrons produced in the collision of cosmic rays, which dominates at low energies, and a new source term of positrons, which dominates at high energies, and (d) a finite energy cutoff of the source term of E_{s}=810_{-180}^{+310} GeV is established with a significance of more than 4σ. These experimental data on cosmic ray positrons show that, at high energies, they predominantly originate either from dark matter annihilation or from other astrophysical sources.

Abstract
CD90 has been identified as a candidate marker of cancer stem cells (CSCs) for HCC, whereas it also has been considered as a marker for tumor-associated fibroblasts (CAFs). OCT4, as a key transcription factor required to maintain pluripotency of human embryonic stem cell and cancer cells, has been characterized to be involved in malignant transformation and tumorigenesis of various cancers. This study aimed to examine expression patterns of CD90 in HCC and investigate whether combination of both CD90 and OCT4 could provide a more powerful predictor for prognosis of HCC than either one alone.CD90 and OCT4 were examined by immunohistochemistry. The relationship between CD90/OCT4 expression and clinicopathologic characteristics was analyzed. The correlation between CD90/OCT4 expression and overall survival and disease-free survival was determined with Kaplan-Meier analysis.CD90 was found mainly expressed in tumor-associated CAFs and OCT4 was mainly expressed in tumor cells. The expression of CD90 and OCT4 in HCC was significantly higher than in adjacent non-tumor and normal liver tissues. CD90 expression was correlated with pathological grade, satellite lesion, PVTT and recurrence. OCT4 expression was correlated with pathological grade, tumor size and recurrence. Data demonstrated no correlation between CD90 and OCT4. High expression of CD90 or OCT4 predicts a poor prognosis. Furthermore, combination of both CD90 and OCT4 provides a more sensitive predictor for prognosis of HCC than either marker alone.CD90 and OCT4 are both independent and reliable biomarker for predicting prognosis of HCC patients after hepatic resection. Our results indicated the accuracy of prediction can be enhanced by their combination.

Immunization with subunits of a novel pilus produced by virulent Clostridium perfringens strains confers partial protection against necrotic enteritis in chickens. Vet Microbiol 2019; 230:7-13.

Abstract
Necrotic enteritis (NE) is an economically important disease of broiler chickens that is caused primarily by Clostridium perfringens strains that produce the NetB toxin. It is controlled in North America principally through the application of in-feed antimicrobials, but alternative control methods, such as vaccination, are urgently needed. We previously identified a cluster of C. perfringens genes prevalent in disease-causing strains, denominated VR-10B, that is predicted to encode a pilus. The current study evaluated the ability of three predicted pilin structural subunits (CnaA, FimA, FimB) to protect against NE in two immunization studies. In the first study, young broiler chickens were immunized twice intramuscularly (i.m.) with CnaA or FimA, which resulted in only a weak serum antibody response, and no reduction in the severity of intestinal lesions following experimental challenge with C. perfringens strain CP1. In the second study, chickens were injected subcutaneously (s.c.) with CnaA, FimB, or a combination of all three proteins, on days 7, 14 and 19, which resulted in a marked antibody response specific to each antigen. Chickens immunized with either CnaA or FimB had significantly reduced NE lesion severity, whereas immunization with all three proteins in combination did not provide protection. Western blot experiments using serum from immunized birds were also performed, providing the first experimental evidence to suggest that this locus may in fact encode a functional pilus structure.
