Abstract
Background: Listeria monocytogenes is one of the deadliest foodborne pathogens, and the bacterium can tolerate severe environments through biofilm formation and antimicrobial resistance. The objective of this study was to investigate the antimicrobial susceptibility, resistance genes,virulence and molecular epidemiology about Listeria from meat processing environments. Methods: This study evaluated the antibiotic resistance and virulence of Listeria isolates from slaughtering and processing plants. All isolates were subjected to antimicrobial susceptibility testing by using a standard microbroth dilution method. The carrying of resistant genes were identified by Polymerase Chain Reaction (PCR). The multilocus sequence typing (MLST) was determined subtyping of the isolates and to characterize possible routes of contamination from meat processing environments. The virulence of different STs of L. monocytogenes isolates were evaluated by Caco-2 cells invasion assay. Results: A total of 59 Listeria isolates were identified from 320 samples, including 37 L. monocytogenes (62.71%). This study evaluated the virulence of L. monocytogenes and antibiotic resistance of Listeria isolates from slaughtering and processing plants. The susceptibility of these 59 isolates against eight antibiotics was analyzed, and the resistance levels to ceftazidime, ciprofloxacin, and lincomycin were as high as 98.31% (L. m 37; L. innocua 7; L. welshimeri 14), 96.61% (L. m 36; L. innocua 7; L. welshimeri 14), and 93.22% (L. m 35; L. innocua 7; L. welshimeri 13) respectively. Over 90% of the isolates were resistant to 3-6 antibiotics, indicating that Listeria isolated from meat processing environments has high antimicrobial resistance. Up to 60% of the isolates carried the tetracycline-resistance genes tetA and tetM. The frequencies of ermA, ermB, ermC, and aac(6’)-Ib were 16.95%, 13.56%, 15.25%, and 6.78%, respectively. Notably, the resistant phenotype and genotype did not match exactly, suggesting that the mechanisms of antibiotic resistance of these isolates were likely related to the processing environment. Multilocus sequence typing (MLST) revealed that 59 Listeria isolates were grouped into 10 sequence types (STs). The dominant L. monocytogenes STs were ST5, ST9, and ST121 in the slaughtering and processing plant of Jiangsu province. Moreover, ST5 subtypes exhibited high invasion in Caco-2 cells compared with ST9 and ST121. Conclusions: The results of this study predict a prevalence of Listeria contamination in the slaughtering and processing plant , and resistance of the ST5 subtypes isolates to the antimicrobials may cause potential public health risks.

Published: June 2021

Abstract
We analyzed published tumor transcriptome data in conjunction with linked survival data to identify genes linked with breast cancer survival outcomes (1, 2). When comparing tumor transcriptomes based on 24-month survival, we discovered that the zinc-finger protein X-linked ZFX (3, 4) was among the most differentially expressed genes in both original and metastatic tumor tissues. ZFX expression was considerably enhanced in metastatic tumors of patients who survived more than 24 months, indicating that enhanced ZFX expression offers a survival advantage for patients with stage IV metastatic breast cancer.

Published: June 2021

Abstract
Background: Peanut (Arachis hypogaea L.) is an important oil and economic crop. Calcium can regulate plant autoimmunity, respond to biotic and abiotic stresses, and improve plant resistance to pathogens. The enrichment of beneficial microorganisms in the rhizosphere is related to plant disease resistance and soil development. The purpose was to analyze the differences of peanut rhizosphere microbial community structure between calcium treatment and control during two growth stages, and the reason that calcium application could improve peanut’s resistance to soil-borne pathogens.. Results: The 16S amplicon sequencing of rhizosphere microbiome showed that calcium application significantly enriched Serratia marcescens and other three dominant strains at the seedling stage. At the pod filling stage, ten dominant stains such as Sphingomonas changbaiensis and Novosphingobium panipatense were enriched by calcium. Serratia marcescens aseptic fermentation filtrate was mixed with PDA medium and inoculated with soil-borne pathogens, which could inhibit the growth of Fusarium solani and Aspergillus flavus at the seedling stage. The fermentation filtrate of Novosphingobium panipatense was mixed with PDA medium and inoculated with main pathogens, which could inhibit the growth of Sclerotium rolfsii and Leptosphaerulina arachidicola.Conclusions: Calcium application enhanced the ability of peanuts to resist pathogens by enriching specific dominant bacteria.

Published: June 2021

Abstract
Rapid molecular diagnosis using nucleic acid biomarkers is important for timely identification of acute pathogenic infections. We introduce an active kinetic approach called sensing single molecule under micromanipulation (SSM3) to quantify nucleic acids, which circumvents hydrodynamic limits of reaction rate, sensitivity and specificity. We demonstrate the 15-minute assay to detect synthetic miRNAs with subfemtomolar limit of detection and high-confidence discrimination of single-base-pair mismatch.

Published: June 2021

Abstract
Background: For countries that have only recently started COVID-19 vaccinations, there remains a key public health question of who should be prioritized for early vaccination. Most vaccine prioritization analyses have only considered variation in risk of infection and death by age. We provide a more granular analysis with stratification by demographics, risk factors, and location. Methods: We used a simulation model to compare the impact of different prioritization strategies on COVID-19 cases, deaths and disability-adjusted life years (DALYs) over the first 6 months of vaccine rollout. We calibrated the model to demographic and location data on 28,175 COVID-19 deaths in California up to December 30, 2020, and incorporated variation in risk by occupation and comorbidity status using published estimates. We estimated the proportion of clinical cases, deaths and DALYs averted relative to a scenario of no vaccination for strategies prioritizing vaccination by a single risk factor (special population status (e.g. incarcerated individual), age, essential worker status, comorbidity status) or multiple risk factors (e.g. age and location). Results: We found that age-based targeting averted the most deaths (65% for 5 million individuals vaccinated) and DALYs (40%) of strategies targeting by a single risk factor and targeting essential workers averted the least deaths (33%) and DALYs (25%) over the first 6 months of vaccine rollout. However, targeting by two or more risk factors simultaneously averted up to 40% more DALYs. Conclusions: Our findings highlight the potential value of multiple-risk-factor targeting of COVID-19 vaccination. Where vaccine supply is limited and logistical challenges in vaccine delivery persist, age-based targeting offers a means of ensuring that vaccines reach those most at risk of poor health outcomes. If operational challenges can be overcome, more granular vaccination strategies that overlap age with other risk factors can be adopted.

Abstract
BackgroundInsomnia is a common sleeping disorder which affects the quality of life which can bring harms to physical and mental health of human beings and even economic development. Traditional Chinese medicine (TCM) plays an outstanding role in treating chronic diseases and alleviating their symptoms. Therefore, the purpose of this study is to assess the treatment efficacy in patients with insomnia treated with abdomen-rubbing qigong exercise (ARQE). In addition, the brain function changes of patients will be explored by resting state functional magnetic resonance imaging(rs-fMRI).Method/designThis trial is a randomized, single-blind, controlled study planned to transpire between July 1, 2020, and July 31, 2021. A sample size of 114 participants (57 per group) with chronic insomnia will be randomly assigned to receive ARQE or CBTI for 8 weeks. The study duration will be 13 weeks, including a 1-week screening period, 8 weeks of intervention, and another 4 weeks of follow-up. The primary outcome is the Pittsburgh sleep quality index scores. Secondary outcomes include insomnia severity index, gastrointestinal symptom rating scale, the Hamilton depression scale, and rs-fMRI scan. The adverse events will be in control. DiscussionThe results of this study will help to clarify the efficacy of ARQE in the treatment of insomnia, and try to use rs-fMRI technology to explore the brain function changes of ARQE in improving sleep quality in patients with insomnia disorder. If the results are as expected, this study will provide high-quality evidence for the treatment of insomnia with ARQE.

Published: June 2021

Abstract
To elucidate the mechanism of myopia development in laser-treated retinopathy of prematurity (ROP) eyes, we investigated the effect of the number of laser shots applied on the myopic variables. A total of 33 eyes of 17 infants with laser-treated ROP were included. Cycloplegic retinoscopic refraction testing was carried out and the spherical equivalent (SE) was calculated. Relationships between SE and various variables (including the number of laser shots applied) were examined. In addition, an age- and axial length (AL)-matched control group without ROP was prepared to compare ocular structural parameters. Although there was no statistical difference in AL between two groups (p = 0.88), SE was significantly more myopic in the ROP group (p < 0.001). SE was associated with AL, corneal refraction (CR), and crystalline lens power (CLP) in the ROP group. Of these three factors (AL, CR, and CLP), only CLP was significantly correlated with the number of laser shots applied (p = 0.003); no correlations were observed between the number of laser shots and AL or CR (p = 0.15 and 0.10, respectively). Very similar tendency was observed in the analysis of the difference between right and left eyes in each child.

Published: June 2021

Abstract
Background: Hepatocellular carcinoma (HCC) is globally recognized as one of the most frequently occurring primary malignant liver tumor, making the identification of HCC biomarkers critically important. Methods: The gene expression and clinicopathology analysis, GO enrichment analysis (GSEA) and immune infiltration analysis are based on data obtained from The Cancer Genome Atlas (TCGA), with additional bioinformatics analyses performed. The statistical analysis was conducted in R. The protein-protein interaction (PPI) networks was constructed and the module analysis was performed using STRING and Cytoscape. Construction and evaluation of prognostic model based on PDRG1 and tumor status used nomogram and calibration.Results: The expression of PDRG1 was significantly higher in HCC tumor tissues. High expression of PDRG1 in HCC patients was significantly correlated with poor Overall Survival and adverse clinicopathological features including advanced T stage, residual tumor, histologic grade, vascular invasion, TP53 status and AFP level. GO, GSEA revealed that PDRG1 was closely correlated with DNA repair, DNA replication and cell cycle. Spearman correlation showed high expression of PDRG1 was significantly correlated with Th2 cells level in HCC patients. Nomograms based on PDRG1 and tumor stage had good predictive performance on overall survival rates of HCC patients.Conclusions: Our study demonstrated the potential significance of PDRG1 expression in the diagnosis and prognosis of HCC and further explored the function in HCC. Further study is still needed to confirm these results. The underlying mechanism revealed by these results provides a basis for PDRG1 as a new molecular target for the prevention and treatment of HCC.

Abstract
Introduction: Encapsulated papillary carcinoma (EPC）of the breast is a rare type of breast cancer with excellent prognosis. It is usually considered a variant of ductal carcinoma in situ (DCIS). However, no consensus on EPC treatment and management has been achieved. We provide some data from our clinical centers to help better manage this disease.Methods: We performed a retrospective analysis of patients diagnosed with EPC from March 2015 to December 2019 at The First Affiliated Hospital of Anhui Medical University. Demographic information, tumor details, immunohistochemical markers, clinical data, stage of the disease, treatment modalities, and oncological outcomes were collected.Results: Eleven cases were included in this retrospective study: three cases had pure EPC, six cases had EPC associated with DCIS, and two cases had EPC associated with invasive cancer. Among the patients, two had lymph node metastases. The mean age of female patients at diagnosis was 53.6 years. The one male patient was 48 years old. The mean tumor size was 2.4 cm. Myoepithelial cell layers were completely absent in all cases. Ten patients were estrogen receptor and progesterone receptor positive and human epidermal growth factor receptor-2 negative. Nine patients underwent mastectomy, and two underwent breast-conserving surgery.Conclusion: Adequate local therapy results in excellent prognosis. Radiation therapy should be offered to patients with EPC who undergo breast-conserving surgery. Immunohistochemistry is necessary in diagnosing EPC and excluding other papillary lesions. Excisional biopsy should be performed to achieve comprehensive diagnosis. Sentinel lymph node biopsy is recommended for patients with EPC.

Abstract
Background Medication overuse headache (MOH) is a growing problem worldwide and is defined as daily or near-daily headache in patients with a primary headache disorder who overuse acute medications. There is debate about whether there are differences in the clinical features and risks of MOH induced by different drugs. Here we investigated the clinical characteristics of patients with MOH following overuse of different acute headache drugs such as triptans and other medications.Methods A multicenter cross-sectional observation study, REgistry for Load and Management of MEdicAtion OveruSE Headache (RELEASE), prospectively collected demographic and clinical data from 114 consecutive patients with MOH according to the International Headache Society criteria between May 2020 and January 2021. We calculated the mean duration until onset of MOH from chronic daily headache (MDMOH), mean monthly frequency of severe headache (MMFSH), mean monthly frequency of seeking medical services (MMFMedS), and mean monthly intake frequency (MMIF) as well as headache impact and neuropsychological tests in patients with MOH after overuse of acute headache drugs.Results A total of 105 eligible MOH patients was included in this study. The patients showed overuse of triptans (31/105, 29.5%), ergotamines (8/105, 7.6%), simple or combination analgesics (37/105, 35.2%), opioids (1/105, 0.9%), and combination of two of more drugs (28/105, 26.7%). The MDMOH was significantly longer for the analgesics group (10.6 years) than the ergotamines (4.1 years), triptans (4.3 years), or multiple drugs group (4.8 years) (p = 0.011, Kruskal–Wallis test). The MMFMedS was lower for the analgesics group (0.37 days per month) than the multiple drugs (0.85 days) or triptans (0.58 days) group (p = 0.008, Kruskal–Wallis test). The MMFSH was significantly lower in the triptans group (7.4 days per month) than in the analgesics (14.4 days) or multiple drugs group (13.7 days) (p = 0.005, Kruskal–Wallis test). The MMIF was higher in the multiple drugs group (25 days per month) than the triptans (18.1 days) or analgesics (19.5 days) group (p = 0.007, Kruskal–Wallis test).Conclusion Data from this prospective multicenter study suggest that the clinical characteristics of MOH depend on the type of overused symptomatic headache medications.

Abstract
Background: The aim of the current study is to investigate the effect of macrophages polarization on the expression of oxytocin (OT) and oxytocin receptor (OTR) in enteric neurons. Methods: In this study, we used a classic colitis model to observe the correlation between macrophages polarization and OT signaling system. In order to further demonstrate the effect of macrophages, we examined the expression of OT signaling system after depletion of macrophages. Results: The data showed that, in vitro, flowing macrophages polarization to M1 type by LPS, the macrophages supernatant inhibited the expression of OT and OTR in cultured enteric neurons through releasing pro-inflammatory cytokines (IL-1β, IL-6 and TNF-α); flowing macrophages polarization to M2 type by IL4, the macrophages supernatant promoted the expression of OT and OTR in cultured enteric neurons through releasing anti-inflammatory cytokine (TGF-β). Furthermore, M1 macrophages decreased the expression of OT signaling system mainly through STAT3/NF-κB pathways in cultured enteric neurons; M2 macrophages increased expression of OT signaling system mainly through activation of Smad2/3 and inhibiting the expression of Peg3 in cultured enteric neurons. In DSS model, we demonstrated that macrophages were polarized to M1 type during the inflammatory phases, the expression of OT and OTR decreased significantly; and macrophages were polarized to M2 type during the recovery phases, the expression of OT and OTR increased significantly. At the same time, we also found that D-mannose increased the expression of OT and OTR through polarization of macrophages to M2 type. Conclusions: This is the first time to prove that the polarization of macrophages differentially regulates the expression of OT and OTR in enteric neurons.

Abstract
Background

The long noncoding RNA gastric cancer associated transcript 3 (GACAT3) has been demonstrated to be implicated in the carcinogenesis and progression of many malignancies. However, GACAT3’s levels and role in esophageal squamous cell carcinoma (ESCC) has not been elucidated.
Methods

GACAT3 amounts were investigated in ESCC tissues and cell lines by qPCR. Its biological functions were examined by CCK-8 assay, colony formation assay, flow cytometry, wound healing assay, transwell assay, and xenograft model establishment. The relationship between GACAT3 and miR-149 was assessed by dual-luciferase reporter assay.
Results

GACAT3 amounts were elevated in ESCC tissue and cell specimens. Functional studies showed that GACAT3 silencing reduced the proliferation, migration and invasion of cultured ESCC cells, and decreased tumor growth in mice. Furthermore, GACAT could directly interact with miR-149. In addition, colony formation and invasion assays verified that GACAT3 promotes ESCC tumor progression through miR-149. Moreover, GACAT3 acted as a competing endogenous RNA (ceRNA) to modulate FOXM1 expression.
Conclusions

These findings indicate that GACAT3 functions as an oncogene by acting as a ceRNA for miR-149 to modulate FOXM1 expression in ESCC, suggesting that GACAT3 might constitute a therapeutic target in ESCC.
Metal speciation and pollution assessment across a small-scale mining creek system tributary
Authors: Austria Elmer S , Fuentes Ericho Jeanne M. , Lamorena-Lim Rheo Baguio 
Published: June 2021

Abstract
Sediment and water samples along Acupan creek were examined to assess the degree of toxic metal pollution due to anthropogenic wastes from small-scale gold mining activity in the area. Samples were collected from five different locations representing the upstream, midstream and downstream areas of the creek. The total concentration of As, Cd, Cu and Pb in the sediment and aqueous matrix were determined. Chemical speciation of the target metals in the creek system was performed using geochemical software PHREEQC. The metal concentrations in the sediments of midstream and downstream were higher compared to the average shale value (ASV) and toxicological reference values (TRV). Similarly, the total metal concentrations of As and Cu in creek water exceeded the local guidelines set for effluent waters. Speciation results identified HAsO42−, Cd2+, CuOH+ and PbOH+ as the major species of the target metals. Metal supersaturation in sediment and low solubility in the aqueous matrix point out to re-suspension and transport of metals as colloidal suspensions. The enrichment factor and geo-accumulation index values indicate significant levels of enrichment and pollution in the midstream and downstream area. The pollution load index confirmed the progressive deterioration of the sediment quality along the creek. Speciation and environmental index results confirmed that anthropogenic sources in the midstream were transported to the downstream catchment.
