Abstract
We report the observation of an intriguing behavior in the transport properties of nanodevices operating in a regime between the Fabry-Pérot and the Kondo limits. Using ultrahigh quality nanotube devices, we study how the conductance oscillates when sweeping the gate voltage. Surprisingly, we observe a fourfold enhancement of the oscillation period upon decreasing temperature, signaling a crossover from single-electron tunneling to Fabry-Pérot interference. These results suggest that the Fabry-Pérot interference occurs in a regime where electrons are correlated. The link between the measured correlated Fabry-Pérot oscillations and the SU(4) Kondo effect is discussed.

Abstract
Egg-type ducks and meat-type ducks are predominantly commercial or indigenous and have been subjected to artificial directional selection. These two duck types differ substantially in body shape, production performance and reproductivity. However, the genetic changes associated with phenotypic differences remain unclear. Here, we compared the two duck types at the genomic and transcriptomic levels. We identified a large number of SNPs and genes in genomic divergent regions in terms of FST and θπ values. The corresponding genes were mainly enriched in embryonic development function and metabolic pathway. RNA-seq analysis also revealed differential gene expression in the liver and gonads. The differentially expressed genes were functionally associated with signal transmission and substance metabolism respectively. Furthermore, we found that seven genes were related to differentiation between the two types by both g genome and transcriptome analysis and were plausible candidate genes. These genes were annotated to GO categories of cell development and disease immunity. These findings will enable a better understanding of the artificial selection history of meat and egg ducks and provide a valuable resource for future research on the breeding of these two lineages.

Abstract
Microbial diversity of pit mud (PM) plays a significant role in Baijiu's flavour. Here we explored the microbial community structures and aroma substances of Wenwang Winery with high-throughput sequencing coupling with headspace solid-phase microextraction-gas chromatography-mass spectrometry. We discovered that the odorant was mainly derived from 14 aroma compounds because of their OAVs ≥ 1 (OAV, the ratio of substance concentration to aroma threshold; s, on behalf of the plural), such as ethyl hexanoate (2438), ethyl octanoate (975), caproic acid (52) and etc. Moreover we also revealed that Lactobacillaceae (97·08%) was the mainly bacterial microbial community in 2-year-old PM, companied by the primarily fungi including Aspergillaceae (55·45%), Unclassified Ascomycota (11·13%) and Dipodascaceae (5·72%). Compared with the 2-year-old PM, bacterial floras in 20-year-old PM and 30-year-old PM were more abundant (i.e. Dysgonomonadaceae, Clostridium and Synerggstaceas), while no fungi were detected. Besides, the physicochemical analysis showed that the content of Lactobacillaceae was inversely associated with moisture, pH and ammonia nitrogen. By further Spearman's correlation coefficient analysis, we verified that the content of Lactobacillaceae was positively correlated with ethyl hexanoate, while negatively correlated with ethyl octanoate and caproic acid. Meanwhile, ethyl octanoate and caproic acid were positively correlated with most flora including Ruminococcaceae, Dysgonomonadaceae and Clostridiacea, which were related to physicochemical indexes. This work demonstrates promise for adjusting the physicochemical indexes of PM to affect the micro-organisms and aroma, which may provide a reference for the production of high-quality Baijiu.

Abstract
The purpose of this study was to identify risk factors for falls in postmenopausal women and provide evidence for the primary prevention of falls in postmenopausal women. The protocol for this meta-analysis is registered with PROSPERO (CRD42020170927). We searched PubMed, the Cochrane Library and EMBASE for observational studies on the risk factors for falls in postmenopausal women. Review Manager 5.3 was used to calculate the relative risk (RR) or weighted mean difference (WMD) of potential risk factors related to falls. STATA 14.0 was used for the quantitative evaluation of publication bias. Eleven studies with 42,429 patients from 7 countries were included. The main risk factors for falls in postmenopausal women were patient sociodemographic risk factors (age: WMD = 0.37, 95% CI 0.07 to 0.68; body weight: WMD = 0.88, 95% CI 0.56 to 1.12; BMI: WMD = 0.34, 95% CI 0.21 to 0.46; exercise: RR = 0.97, 95% CI 0.94 to 0.99; and FES-I: WMD = 6.60, 95% CI 0.72 to 12.47) and medical risk factors (dietary calcium intake: WMD = - 16.91, 95% CI - 25.80 to - 8.01; previous fracture history: RR = 1.21, 95% CI 1.13 to 1.29; previous falls: RR = 2.02, 95% CI 1.91 to 2.14; number of diseases, ˃ 2: RR = 1.17, 95% CI 1.11 to 1.23; and number of reported chronic health disorders: WMD = 0.30, 95% CI 0.10 to 0.49). Knowledge of the many risk factors associated with falls in postmenopausal women can aid in fall prevention. However, we cannot rule out some additional potential risk factors (age at the onset of menopause, years since last menstruation, hormone therapy and BMD) that need further clinical research.

Abstract
Evidence indicates that microRNAs (miRNAs) play essential roles in early embryonic development. The miRNA-518 family is a special biomarker of the placenta, and miRNA-518b is abnormally expressed in placental tissue in preeclampsia. Early growth response protein 1 (EGR1), a zinc finger transcriptional factor, plays an essential role in regulating cell differentiation, angiogenesis, and migration. Moreover, earlier studies have shown that EGR1 protein plays a key role in implantation. However, little is known about the role of miR-518b and EGR1 on early embryonic arrest (EEA) in humans. In our study, increased miR-518b along with decreased EGR1 was found in human villus tissues with EEA. Furthermore, we demonstrated by luciferase assay that miR-518b is a direct regulator of EGR1. After comparing the effect of silencing EGR1, vascular endothelial growth factor (VEGF) individually, and EGR1/VEGF in combination, we found that EGR1 can inhibit migration and angiogenesis of HTR-8 SVneo cells by decreasing the VEGF expression. Hypoxia plays an initial role in early embryonic development, and we found that hypoxia reduces the expression of miR-518b and increases the expression of EGR1 and VEGF to facilitate migration and angiogenesis in a hypoxic model of HTR-8/SVneo cell line. Our findings provide new insights into the role of miR-518b in EEA and implicate the potential application of miR-518b in the diagnosis and development of intervention for EEA.

Abstract
Naringenin is a flavonoid compound with antioxidant effects. It is used to treat oxidative stress-related diseases, but its mechanism is unclear. In this experiment, we explored whether naringenin can increase the expression of superoxide dismutase 1(SOD1), reduce the oxidative stress of PC12 cells induced by homocysteine (Hcy), and decrease the apoptosis of PC12 cells induced by Hcy by inhibiting the expression of mir-224-3p. Different concentrations of Hcy (1, 3, 5, 8, and 10 mmol/L) was used to analyze effect of homocysteine on PC12 cells. A total of 5 mmol/L Hcy was used to induce the excitatory and neurotoxicity model of PC12 cells in vitro. The cells were divided into normal control, Hcy induction, Hcy + Naringenin (25 μM), Hcy + Naringenin (50 μM), Hcy + Naringenin (75 μM), Hcy + Naringenin (100 μM), and Hcy + Naringenin (150 μM) groups. The relative survival rate and activities of the PC12 cells were determined by the MTT method, and the apoptosis rate of the PC12 cells was determined by using flow cytometry. The Western blot method was used to determine the expressions of SOD1, Bax, Caspase-3, Caspase-8, and Bcl-2 in the PC12 cells induced by Hcy. The expressions of SOD1 mRNA and miR-224-3p in the Hcy-induced PC12 cells were determined by RT-PCR. Results found that Hcy increased the expression of miR-224-3p in a dose-dependent manner but decreased that of SOD1 mRNA and protein. Hcy also increased oxidative stress in the PC12 cells and the proapoptotic proteins Bax, Caspase-3, and Caspase-9. Furthermore, it decreased the expression of anti-apoptotic protein Bcl-2 and the activity and survival rate of the HT22 cells, but it increased the apoptosis of the PC12 cells. The treatment of Hcy-induced PC12 cells with different concentrations of naringenin for 24 h decreased the expression of miR-224-3p in a dose-dependent manner and increased the expressions of SOD1 mRNA and protein. The treatment also decreased the oxidative stress in the PC12 cells and the expressions of pro-apoptotic proteins Bax, Caspase-3, and Caspase-9; increased the expression of anti-apoptotic protein Bcl- 2; decreased the apoptosis of the PC12 cells; and increased the PC12 cells.The results suggest that Naringenin can decrease the apoptosis and oxidative stress of PC12 cells induced by Hcy and increase the activities and survival rates of PC12 cells. The mechanism may be related to naringenin decreasing the expression of miR-224-3p in PC12 cells induced by Hcy and increasing the expressions of SOD1 mRNA and protein.

Abstract
Objective: To observe preventive effect of intestinal stent against anastomotic leakage after rectal cancer operation. Methods: A retrospective cohort study was carried out. Clinical data of 107 patients with low rectal cancer undergoing laparoscopic radical resection from January 2015 to August 2019 were retrospectively analyzed. Intestinal stent was placed intraoperatively in 48 cases and was not placed in 59 cases. Postoperative Wexner score for anal function and incidence of anastomotic leakage were compared between patients with and without intstinal stent. Results: There was no significant differences in age, distance between tumor and the anal verge, operative time and postoperative Wexner score for anal function between the two groups (all P>0.05). After a month of follow-up, the incidence of anastomotic leakage was 16.9% (10/59) in the non-stent group, while no anastomotic leakage was found in the stent group (P=0.002). Conclusion: Placement of intestinal stent can effectively prevent anastomotic leakage after low rectal cancer surgery.

Abstract
Iron is one of the most studied chemical elements due to its sociotechnological and planetary importance; hence, understanding its structural transition dynamics is of vital interest. By combining a short pulse optical laser and an ultrashort free electron laser pulse, we have observed the subnanosecond structural dynamics of iron from high-quality x-ray diffraction data measured at 50-ps intervals up to 2500 ps. We unequivocally identify a three-wave structure during the initial compression and a two-wave structure during the decaying shock, involving all of the known structural types of iron (α-, γ-, and ε-phase). In the final stage, negative lattice pressures are generated by the propagation of rarefaction waves, leading to the formation of expanded phases and the recovery of γ-phase. Our observations demonstrate the unique capability of measuring the atomistic evolution during the entire lattice compression and release processes at unprecedented time and strain rate.

Abstract
Background:Osteoporosis and renal insufficiency are coexisting disease states in a substantial proportion of postmenopausal women. Since bisphosphonates are generally contraindicated in patients with estimated glomerular filtration rate (eGFR) <35 mL/min, it is important to evaluate other osteoporosis treatments in this setting.Objectives:To determine if baseline renal function affects the efficacy and safety of romosozumab.Methods:We performed post hoc analyses of two clinical trials of romosozumab in postmenopausal women with osteoporosis. In ARCH (NCT01631214), 4,093 patients were randomised 1:1 to romosozumab 210 mg monthly or alendronate 70 mg weekly for 12 months (mean age: 74.3 years; 96.1% with prevalent vertebral fractures [VFx]). In FRAME (NCT01575834), 7,180 patients were randomised 1:1 to romosozumab 210 mg or placebo monthly for 12 months (mean age: 70.9 years; 18.3% with prevalent VFx). For these analyses, patients were categorised by baseline eGFR (mL/min/1.73m2): normal renal function (eGFR ≥90), mild renal insufficiency (eGFR 60–89), or moderate renal insufficiency (eGFR 30–59). Least squares mean (LSM) percent change from baseline in bone mineral density (BMD) at the lumbar spine, total hip, and femoral neck; incidence of new VFx and adverse events (AEs); and changes in renal function were assessed for each eGFR category at Month 12 of the double-blind treatment period.Results:At baseline, most patients had mild/moderate renal insufficiency: 84% in ARCH, 88% in FRAME. In both studies, change from baseline in BMD was significantly higher in the romosozumab group across baseline eGFR categories (Figure). There was an interaction between BMD increase and renal function, and although BMD increase was not as large in women with impaired renal function, differences between romosozumab and control groups remained significant (Figure). In ARCH, among patients with eGFR ≥90, 60–89, and 30–59, the incidence of new VFx (romosozumab vs alendronate) at Month 12 was 3.3% vs 7.3%, 3.2% vs 3.9%, and 3.4% vs 6.2% in ARCH. In FRAME, the incidence of new VFx (romosozumab vs placebo) at Month 12 was 0.5% vs 3.0%, 0.4% vs 1.5%, and 0.6% vs 2.1%.In both studies, the incidences of AEs and serious AEs were similar in both treatment groups within and across eGFR categories. AEs of mild-to-moderate hypocalcaemia (investigator reported) occurred in two patients in ARCH (one romosozumab [eGFR 60–89] and one alendronate [eGFR ≥90]), and one patient in FRAME (romosozumab [eGFR 60–89]). Five patients in ARCH (all in the alendronate group) and 19 patients in FRAME (14 romosozumab, 5 placebo) had decreases in serum Ca levels (albumin adjusted); in the romosozumab group all were mild (<LLN–8.0 mg/dL) or moderate (<8.0–7.0 mg/dL). A similar percentage of patients in each group had changes in renal function over 12 months of treatment.Conclusion:The efficacy and safety of romosozumab vs alendronate or placebo was similar among postmenopausal women with osteoporosis and different levels of renal function.Acknowledgments:This study was funded by Amgen, Astellas and UCB Pharma.

Abstract
Objective: To explore the effect of phenolamine on the outcome and prognosis of patients with myocardial injury due to sepsis. Methods: From January 2015 to December 2017, 62 septic patients with myocardial injury were randomly divided into study group (n=32) and control group (n=30). Two groups were given conventional treatment, while the study group was treated with phentolamine. The NT-pro brain natriuretic pepitide (NT-proBNP), cardiac troponin I (cTnI), lactate dehydrogenase (LDH), creatine kinase isoenzymes (CK-MB) and tumor necrosis factor (TNF)-α, high-sensitivity C-reactive protein (hs-CRP), interleukin (IL)-1β, IL-6 were detected at 0,12, 24, 48, 72 h and 7 d after hospitalization. And left ventricular ejection fraction (LVEF), e', E and A in each time period were observed. The 28 d survival rate and length of ICU stay were observed in both groups. The data were compared with single sample t test between the two groups. Results: After 12, 24, 48, 72 h and 7 d, NT-proBNP, cTnI, LDH, CK-MB, TNF-α, hs-CRP, IL-1β, IL-6 in the study group were all significantly lower than those in the control group (all P<0.05). The cardiac function indexes of LVEF, E/A and E/e' in the study group were all significantly improved when compared with those in the control group (all P<0.05). The length of ICU stay and 28-day mortality in the study group were significantly lower than those in the control group ((9.8±3.6) d vs (13.0±4.1) d, t=3.152, P=0.004; 21.9% vs 36.7%, χ(2)=5.078, P=0.021). Conclusion: Combined application of phentolamine can significantly improve the outcome of sepsis patients with myocardial injury and improve the survival rate.

Abstract
PURPOSE Type 3 innate lymphocytes (ILC3s) are reported to be involved in lung cancer, possibly by producing interleukin-22 (IL-22). However, whether ILC3s and their secreted IL-22 molecules contribute to the pathogenesis of pancreatic cancer (PC) remains unclear. To this end, in this study, we investigated the effects and possible mechanisms of ILC3s on PC pathogenesis. METHOD The IL-22 and IL-2i2R levels and the ILC3s' frequency in cancer tissues from PC patients and in peripheral blood from PC patients and healthy controls were analyzed by flow cytometry, immunochemistry, or immunofluorescence. The effects of IL-22-induced AKT signaling on the proliferation, invasion, and migration of PC cells were examined by co-culturing PC cell lines with ILC3s isolated from PC tissues, with or without the addition of neutralizing IL-22 antibody, IL-22R antibody or AKT inhibitor. RESULTS Our results showed that IL-22 and ILC3s were significantly upregulated in the PBMCs and cancer tissues of PC patients, and the IL-22R level was increased in PC cells. The increased frequency of ILC3s was positively correlated with the clinical features of PC patients. Co-culture experiments indicated that ILC3s promoted the proliferation, invasion, and migration of PC cell lines by secreting IL-22 to activate AKT signaling because IL-22/IL-22R or AKT blockage markedly counteracted such effects on PC cells. CONCLUSION Our data demonstrated that ILC3s may promote PC pathogenesis through IL-22/IL-22R-AKT signaling, suggesting a potential intervention target for PC treatment in the future.

Abstract
UNLABELLED Romosozumab, a sclerostin antibody, exerts dual effect to increase bone formation and decrease bone resorption. Among high-risk postmenopausal East Asian women, romosozumab followed by alendronate was associated with lower incidences of fractures vs alendronate alone. Romosozumab demonstrates potential to address an unmet need in osteoporosis management in Asia. INTRODUCTION Romosozumab, a sclerostin antibody, exerts dual effect to increase bone formation and decrease bone resorption. The global ARCH study demonstrated superiority of romosozumab followed by alendronate in reducing fracture risk in high-risk postmenopausal osteoporotic women vs alendronate alone. We report outcomes among ARCH East Asian patients. METHODS In ARCH, 4093 postmenopausal osteoporotic women with fragility fracture were randomized 1:1 to monthly romosozumab 210 mg or weekly alendronate 70 mg for 12 months, both followed by open-label alendronate. Primary endpoints were incidence of new vertebral fracture (VF) at 24 months and clinical fracture at primary analysis (confirmed fractures in ≥ 330 patients and all patients had opportunity to attend month 24 visit). This post hoc analysis was not powered to detect fracture-rate differences. RESULTS This analysis included 275 patients from Hong Kong, Korea, and Taiwan. Romosozumab followed by alendronate reduced risk of new VFs at 24 months by 60% (P = 0.11) and clinical fractures at primary analysis by 44% (P = 0.15) vs alendronate alone. Romosozumab followed by alendronate significantly increased mean bone mineral density at 24 months from baseline by a further 9.0%, 3.3%, and 3.0% at the lumbar spine, total hip, and femoral neck vs alendronate alone. Adverse event (AE) rates, including positively adjudicated serious cardiovascular AEs (1.6% vs 1.4% at 12 months for romosozumab vs alendronate), were similar across treatment groups. CONCLUSIONS Consistent with the global analysis, romosozumab followed by alendronate was associated with lower incidences of new vertebral, clinical, non-vertebral, and hip fractures vs alendronate alone among East Asian patients.

Abstract
Case history: A 2-year-old Rottweiler dog from Perth (WA, Australia) was referred for assessment of a chronic productive cough and weight loss.Clinical findings: Severely enlarged bilateral superficial cervical lymph nodes and severely enlarged abdominal organs were present. The body condition score was poor and there was moderate muscle wasting. Thoracic and abdominal computed tomography images revealed severe diffuse enlargement of thoracic and abdominal lymph nodes, hepatomegaly and diffuse splenomegaly. A diffuse bronchial pattern with severe multifocal saccular bronchiectasis was identified in the lungs.Diagnostic findings: Fungal organisms were seen within macrophages on cytological preparations and on histopathological sections of biopsies of the superficial cervical lymph node. Macrophages contained intracytoplasmic, non-filamentous round-to-ovoid organisms, which varied in size from 5-30 µm in diameter with variable morphology. Budding was not observed, and no hyphae were present. Fungal culture of lymph node tissue resulted in growth of Aspergillus (Phialosimplex) caninus which was confirmed by amplification and sequencing of a segment of the 16S-23S rRNA internal transcribed spacer. Concurrent bacterial bronchitis was diagnosed on culture of broncho-alveolar fluid.Diagnosis: Disseminated aspergillosis caused by Aspergillus caninus.Clinical relevance: This is believed to be the first report of infection caused by A. caninus in a dog in Australasia. The dog was treated with itraconazole for 7 months and was still alive 7 months after the start of treatment.

Abstract
A Third Party Copy (TPC) mechanism has existed in the pure XRootD storage environment for many years. However, using the XRootD TPC in the WLCG environment presents additional challenges due to the diversity of the storage systems involved such as EOS, dCache, DPM and ECHO, requiring that we carefully navigate the unique constraints imposed by these storage systems and their site-specific environments through customized configuration and software development. To support multitenant setups seen at many WLCG sites, X509 based authentication and authorization in XRootD was significantly improved to meet both security and functionality requirements. This paper presents architecture of the pull based TPC with optional X509 credential delegation, and how it is implemented in native XRootD and dCache. The paper discusses technical requirements, challenges, design choices and implementation details in the WLCG storage systems, as well as in FTS/gfal2. It also outlines XRootD’s plan to support newer TPC and security models such as token based authorization.
