Abstract
The objective of this study was to identify the relative contribution of tenderness factors for three beef muscles with similar tenderness ratings. Longissimus lumborum (LL), tensor fascia latae (TF) and gastrocnemius (GC) were collected from 10 USDA low Choice beef carcasses and assigned to a 5 or 21 days aging period (n = 60). Sarcomere length, troponin-T degradation, collagen content, mature collagen crosslink density, intramuscular lipid content and trained panel analysis were measured. Correlation and multivariate regression analysis indicated each muscle has a specific tenderness factor that contributed to the overall tenderness evaluated by trained panelists. The equations indicated LL tenderness was driven by lipid content (P < .05); TF tenderness was driven by collagen content (P < .05). GC tenderness was driven by proteolysis (P < .01), and only collagen content can be casually used as an overall tenderness predictor for all three cuts.

Abstract
OBJECTIVE: To quantify the relationship between strength and endurance of knee extensor and flexor and exercise capacity in patients with chronic obstructive pulmonary disease (COPD).METHODS: A total of 108 patients with stable COPD (age: 65 years, IQR25-75: 59-72) were enrolled in this cross-sectional study. Knee extensor and flexor function was evaluated using the isokinetic test, and the parameters attained were considered as independent variables. Exercise capacity was evaluated using 6-minute walking test (6MWT) and 30-second sit-to-stand test (30s SST), and the results were considered as dependent variables. The association between lower-limb muscle function and exercise capacity was assessed using multiple regression analysis.RESULTS: The patients mostly had moderate-to-severe airflow obstruction with a post-bronchodilator forced expiratory volume in 1 second (FEV1) of 57.87 ± 17.71% predicted. In multiple regression analysis, flexor total work (TW), extensor endurance ratio (ER), age and FEV1%pred were significantly associated with 6MWT (adjusted R² = 0.455, P < 0.001). Flexor TW and age were significantly associated with 30s SST (adjusted R² = 0.355, P < 0.001).CONCLUSION: Knee endurance has a significant relationship with exercise capacity, and knee flexor endurance seems to be an important factor contributing to exercise capacity in COPD patients.

Abstract
This study aimed to investigate the effect of resveratrol on methane production, rumen fermentation and microbial composition under high-concentrate (HC) and high-forage (HF) diets using the in vitro fermentation system. A total of 25 mg of resveratrol was supplemented into 300 mg of either HC or HF diet. Methane production, total volatile fatty acid (VFA) concentration, molar proportion of VFA, metabolites of resveratrol and prokaryotic community composition were measured after 12 and 24 h of in vitro fermentation. Resveratrol reduced methane production (ml per mg of dry matter degraded) by 41% and 60% under both HC and HF diets (P < 0.001), respectively, and this result could be associated with the lower abundance of Methanobrevibacter (P < 0.001) in response to resveratrol. The molar proportion of propionate was significantly higher in the resveratrol group only under the HC diet (P = 0.045). The relative abundance of 10 bacterial genera was affected by the three-way interaction of treatment, diet and time (P < 0.05). Resveratrol was partly converted to dihydroresveratrol after 24 h of fermentation, and its degradation could be associated with microbes belonging to the order Coriobacteriales. Our results suggest that multiple factors (e.g. diet and time) should be considered in animal experiments to test the effect of polyphenol or other plant extracts on rumen fermentation, methane emission and microbial composition.

Abstract
PURPOSE The supply of non-iodized salt and the water improvement project have been conducted to reduce the iodine concentration in drinking water in areas with elevated water iodine. We aimed to assess the impact of water iodine concentration (WIC) on the iodine intake of pregnant women in areas with restricted iodized salt supply, and determine the cutoff values of WIC in areas with non-iodized salt supply. METHODS Overall, 534 pregnant women who attended routine antenatal outpatient visits in Zibo Maternal and Child Health Hospital in Gaoqing County were recruited. The 24-h urine iodine excretion (UIE) in 534 samples and the iodine concentration in 534 drinking water samples were estimated. Urinary iodine excretion, daily iodine intake, and daily iodine intake from drinking water (WII) were calculated. The relationship between WIC and daily iodine take was analyzed. RESULTS The median WIC, spot urine iodine concentration (UIC), and 24-h UIE were 17 (6, 226) μg/L, 145 (88, 267) μg/L, and 190 (110, 390) μg/day, respectively. A significant positive correlation was found between WIC and UIE (R2 = 0.265, p < 0.001) and UIC (R2 = 0.261, p < 0.001). The contribution rate of WII to total iodine intake increased from 3.0% in the group with WIC of < 10 μg/L to 45.7% in the group with WIC of 50-99 μg/L. CONCLUSION The iodine content in drinking water is the major iodine source in pregnant women living in high-water iodine areas where iodized salt supply is restricted. The contribution rate of daily iodine intake from drinking water increases with the increase in water iodine concentration.

Abstract
Research into the production of white sesame oil by aqueous extraction has been promoted because of concerns about the environment, health, and cost. The advanced aqueous method using a 1.95:10 liquid-to-raw material ratio, which was finally developed in this study, recovered 96.06% white sesame oil and produced de-oiled meal with high quality (3.98% residual oil content). The acid value and peroxide value of the oil produced were quite low at 0.19 mg KOH/kg and < 3.25 mmol/kg, respectively, which were better than the values required by the Chinese national standard for first class edible sesame oils and oils produced by hexane extraction. No wastewater was discharged during the extraction of white sesame oils by an aqueous salt solution. The protein rich de-oiled meal may be a good material for making protein isolate with high purity (e.g. > 90%). It can also be a nutritious ingredient or raw material for producing many food products.

Abstract
Three chops from 20 pork carcasses were aged for 1, 8, and 21 days. Electrospray ionization-tandem mass spectrometry was used to comprehensively analyze profiles of phospholipids from each sample (n = 60). Total phospholipid quantity decreased 4-folds (P < .01) from 1 to 21 days of aging in pork loins. Phosphatidylinositol (PI) and phosphatidylserine (PS) increased by 30% and 73%, respectively, from 1 to 21 days of aging in pork loins (P < .01). This increase was mainly due to relative percentage increase from PI 38:4 (18:0-20:4) and PS 36:2 (18:0-18:2; P < .01). The results also showed that the relative percentage of lysophosphatidylcholine increased by 35% after short term aging (8d), and phosphatidic acid increased by 10-folds after extended aging (21d; P < .01). These results documented that phospholipids undergo enzymatic hydrolysis during aging, but also indicated that lipid species containing 18:2 or 20:4 within PI and PS were slightly more resistant to enzymatic hydrolysis compared with the other phospholipids.

Abstract
A search for millicharged particles, a simple extension of the standard model, has been performed with the ArgoNeuT detector exposed to the Neutrinos at the Main Injector beam at Fermilab. The ArgoNeuT liquid argon time projection chamber detector enables a search for millicharged particles through the detection of visible electron recoils. We search for an event signature with two soft hits (MeV-scale energy depositions) aligned with the upstream target. For an exposure of the detector of 1.0×10^{20} protons on target, one candidate event has been observed, compatible with the expected background. This search is sensitive to millicharged particles with charges between 10^{-3}e and 10^{-1}e and with masses in the range from 0.1 to 3 GeV. This measurement provides leading constraints on millicharged particles in this large unexplored parameter space region.

Abstract
Based on column approximation (CA) assumption, many-beam Schaeublin-Stadelmann diffraction equations are employed for simulating the transmission electron microscopy (TEM) diffraction image contrast of dislocation loops within thin TEM foil of finite thickness, and two beam and many beam diffraction conditions are compared. Moreover, the effects of materials anisotropy and free surface relaxation induced elastic fields distortion of dislocation loops on the black-white image contrast are specially focused. It is found that anisotropy has a remarkable impact on the TEM image contrast of dislocation loop, and free surface relaxation induced image forces can change the black-white contrast features when dislocation loops are near TEM foil free surfaces. Thus, in order to make reliable judgment on the nature of defects, effects of free surface and anisotropy should be included when analysing irradiation induced dislocation loops and other type of defects in in-situ electron, proton, heavy-ion irradiation experiments under TEM environments.

Abstract
In the present study, a method for screening non-aflatoxigenic Aspergillus flavus in soil samples collected from major peanut-growing regions of China was developed. The single colonies were picked and cultured on Aspergillus flavus and parasiticus agar (AFPA). If the reverse side of the colony on AFPA was orange-coloured, it was considered A. flavus or Aspergillus parasiticus. After the genomic DNA of each strain was extracted, 28S rRNA and calmodulin were amplified and sequenced to determine the species. The key gene, aflR, was amplified and digested via polymerase chain reaction-restriction fragment length polymorphism. The aflatoxigenic A. flavus and the non-aflatoxigenic A. flavus and A. parasiticus were distinguished by enzyme digestion of aflR. 156 strains of A. flavus were screened, which consisted of 135 aflatoxigenic and 21 non-aflatoxigenic strains. The aflatoxin producing ability of each strain was confirmed using solid-state fermentation experiments. Using the method developed in the present study, we confirmed that the non-aflatoxigenic A. flavus strains isolated lost their capacity to produce aflatoxins. Considering there could be some alterations in other functional genes, some non-aflatoxigenic strains could be identified inaccurately as aflatoxigenic strains, although that did not occur in the present study. The growth of non-aflatoxigenic A. flavus was observed, and the most rapidly growing non-aflatoxigenic strain was selected for plate confrontation assays and toxic mixed culture experiments. The inhibition rate of non-aflatoxigenic A. flavus against aflatoxigenic A. flavus was 55.4 and 72.6% in potato dextrose agar (PDA) plate and natural soybean medium, respectively. The screened non-aflatoxigenic A. flavus strains provide a microbial resource for biological control of aflatoxin contamination.

Abstract
To investigate the early changes of peripheral blood leukocyte differential counts in patients with COVID-19. Ten patients with COVID-19 and 30 patients with other viral pneumonia (non-COVID-19) admitted to Shanghai Jiao Tong University Affiliated Sixth People's Hospital and Jinshan Branch Hospital from January 22 to February 17, 2020 were enrolled in this study. The differential counts of white blood cells were analyzed. Patients in COVID-19 group showed relatively lower absolute white blood cell (WBC) count 4.95(3.90,6.03)×10(9)/L, lymphocyte absolute count 1.20(0.98,1.50)×10(9)/L and eosinophil absolute count 0.01(0.01,0.01)×10(9)/L. Leukopenia developed in two patients(2/10), lymphocytopenia also in two patients(2/10). Seven over ten patients presented with eosinophil cytopenia. In non-COVID-19 group, absolute WBC count was 8.20 (6.78,9.03) ×10(9)/L (P<0.001), lymphocyte absolute count 1.75(1.20,2.53)×10(9)/L(P=0.036), eosinophil absolute count 0.02(0.01,0.03)×10(9)/L(P=0.05). Lymphocytopenia occurred in (16.7%) patients, eosinophil cytopenia in 16.7% patients too. In conclusion, leukopenia, lymphocytopenia and eosinophil cytopenia are more common in COVID-19 patients than those in non- COVID-19 patients.

Abstract
Immune checkpoint inhibition has revolutionized the treatment of several solid cancers, most notably melanoma and non-small-cell lung cancer (NSCLC). Drugs targeting cytotoxic T lymphocyte antigen (CTLA)-4 and programmed cell death 1 (PD-1) have made their way into routine clinical use; however, this has not been without difficulties. Stimulation of the immune system to target cancer has been found to result in a reduction of self-tolerance, leading to the development of adverse effects that resemble autoimmunity. These adverse effects are erratic in their onset and severity and can theoretically affect any organ type. Several mechanisms for immune-related toxicity have been investigated over recent years; however, no consensus on the cause or prediction of toxicity has been reached. This review seeks to examine reported evidence for possible mechanisms of toxicity, methods for prediction of those at risk and a discussion of future prospects within the field.

Abstract
Objective: To investigate chromosome abnormality rate and related factors of spontaneous abortion in early pregnancy. Methods: A total of 831 tissue samples of spontaneous abortion in early pregnancy were collected from June 2015 to August 2018 in the First Affiliated Hospital of Nanjing Medical University. Chromosomal copy number was analyzed by next generation sequencing (NGS). The relationships between chromosome abnormality and maternal age, in vitro fertilization-embryo transfer (IVF-ET) pregnancy, number of previous spontaneous abortions, history of live birth were analyzed by statistical methods. Results: Among 831 tissue samples of spontaneous abortion in early pregnancy, 461 (55.5%, 461/831) were found to have chromosome abnormalities. Maternal age (OR=1.107, 95%CI: 1.070- 1.145) and history of live birth (OR=1.909, 95%CI: 1.182-3.083) were the positive correlative factors of chromosome abnormality. Times of previous spontaneous abortion (OR=0.807, 95%CI: 0.702-0.928) and IVF-ET pregnancy (OR=0.554, 95%CI: 0.404-0.760) were the negative correlative factors of chromosome abnormality. Conclusions: Chromosome abnormality is an important cause of spontaneous abortion in early pregnancy. The rate of chromosome abnormality increases with the increase of maternal age and the history of live birth, and decreases with the increase of number of previous spontaneous abortion and IVF-ET pregnancy.

Abstract
Objective: To explore the incidence and clinical characteristics of sarcopenia in hospitalized elderly patients with coronary heart disease and search for the related factors. Methods: This study was a single-center observational study. According to the inclusion criteria, elderly patients hospitalized with coronary heart disease from Peking Union Medical College Hospital between December 2017 and December 2018 were enrolled. The patients were divided into sarcopenic group and non-sarcopenic group according to the diagnostic criteria of the Asian Working Group for Sarcopenia. Activities of daily living of the patients were assessed (including ADL and IADL) . Comorbidity of the patients was evaluated by the Charlson comorbidity index (CCI). Long-term medication use of the patients was recorded to assesse whether there was polypharmacy. The nutritional status of the patients was examined by the mini nutritional assessment-short form (MNA-SF). The full tandem stance time of the patients was evaluated. The history of falls over the previous year, urinary incontinence, and living conditions of the patients were also recorded. Multivariate logistic regression was used to analyze the related factors for sarcopenia of elderly patients with coronary heart disease. Results: A total of 364 patients were enrolled in the study. The patients were aged 65-96 (74.6±6.5) years and there were 218 (59.9%) male patients. There were 264 cases of stable coronary heart disease and 100 cases of acute coronary syndrome. The median number of long-term used medication was 7. One hundred and fifty-two (41.8%) patients were complicated with type 2 diabetes, 38 (10.4%) patients were complicated with anxiety/depression, and 98 (26.9%) patients had the history of falls over the previous year. Eighty-two (22.5%) patients were complicated with urinary incontinence, 12 patients (3.3%) were complicated with malnutrition and 33 patients (9.2%) were living alone. There were 81 (22.3%) sarcopenic patients and 283 (77.7%) non-sarcopenic patients among all the hospitalized elderly patients with coronary heart disease. The sarcopenic patients were more older, with lower body mass index(BMI)(both P<0.001), higher CCI and more long-term used medication (both P<0.05), higher proportions of malnutrition, urinary incontinence, history of falls, and living alone (all P<0.05) compared to non-sarcopenic patients. ADL and IADL scores of sarcopenic patients were significantly lower than those of non-sarcopenic patients (both P<0.001). There was also a higher proportion of unable to accomplish full tandem stance among sarcopenic patients compared to non-sarcopenic patients (P<0.001). Moreover, higher hs-CRP level (P=0.047) , lower albumin level (P=0.004) and significantly lower prealbumin level (P<0.001) were observed in sarcopenic patients compared to non-sarcopenic patients. Stepwise multivariate binomial logistic regression analysis revealed that male (OR=5.036, 95%CI 1.782-14.230, P=0.002), low BMI (OR=0.883, 95%CI 0.796-0.980, P=0.019), as well as low prealbumin level (OR=0.990, 95%CI 0.980-1.000, P=0.045) were related factors for sarcopenia among elderly patients with coronary heart disease. Conclusions: Sarcopenia is a geriatric condition commonly seen in hospitalized elderly patients with coronary heart disease. Male, low BMI, and low prealbumin level were the factors related to sarcopenia for older adults with coronary heart disease.

Abstract
Objective: To understand the consistency of ALK Ventana-D5F3 immunohistochemistry (IHC) interpretation in Chinese lung adenocarcinoma among histopathologists from different hospitals, and to recommend solution for the problems found during the interpretation of ALK IHC in real world, with the aim of the precise selection of patients who can benefit from ALK targeted therapy. Methods: This was a multicenter and retrospective study. A total of 109 lung adenocarcinoma cases with ALK Ventana-D5F3 IHC staining were collected from 31 lung cancer centers in RATICAL research group from January to June in 2018. All cases were scanned into digital imaging with Ventana iSCANcoreo Digital Slide Scanning System and scored by 31 histopathologists from different centers according to ALK binary (positive or negative) interpretation based on its manufacturer's protocol. The cases with high inconsistency rate were further analyzed using FISH/RT-PCR/NGS. Results: There were 49 ALK positive cases and 60 ALK negative cases, confirmed by re-evaluation by the specialist panel. Two cases (No. 2302 and No.2701) scored as positive by local hospitals were rescored as negative, and were confirmed to be negative by RT-PCR/FISH/NGS. The false interpretation rate of these two cases was 58.1% (18/31) and 48.4% (15/31), respectively. Six out of 31 (19.4%) pathologists got 100% accuracy. The minimum consistency between every two pathologists was 75.8%.At least one pathologist gave negative judgement (false negative) or positive judgement (false positive) in the 49 positive or 60 negative cases, accounted for 26.5% (13/49), 41.7% (25/60), respectively, with at least one uncertainty interpretation accounted for 31.2% (34/109). Conclusion: There are certain heterogeneities and misclassifications in the real world interpretation of ALK-D5F3 IHC test, which need to be guided by the oncoming expert consensus based on the real world data.

Abstract
PURPOSE To investigate the prevalence of feeding difficulties in preschool children and explore the association between caregivers' anxiety and depression symptoms and preschool children's feeding difficulties. METHODS This cross-sectional study was conducted between June 2017 and January 2018 in rural areas of Anhui province, China. A total of 2231 preschool children and their caregivers were interviewed. Feeding difficulties of preschool children were reported by caregivers using the adapted Identification and Management of Feeding Difficulties (IMFeD) tool. Anxiety and depression symptoms of caregivers were evaluated via the Self-Rating Anxiety Scale (SAS) and the Self-Rating Depression Scale (SDS). RESULTS In total, 54.1% of preschool children were reported to have feeding difficulties by their caregivers. Among all children, when the caregivers had symptoms of anxiety or depression, the children had a higher risk of feeding difficulties. Specifically, for caregivers' anxiety symptoms, the odds ratios (ORs) of feeding difficulties in all children, left-behind children (LBC), and non-LBC were 1.91 (95% confidence interval [CI]: 1.42-2.57), 2.04 (95% CI: 1.34-3.09), and 1.86 (95% CI: 1.21-2.87), respectively; for caregivers' depression symptoms, the ORs of feeding difficulties in all children, LBC, and non-LBC were 1.86 (95% CI: 1.46-2.39), 1.76 (95% CI: 1.24-2.51), and 2.08 (95% CI: 1.45-2.97), respectively. In addition, when caregivers who were parents or grandparents had anxiety or depression symptoms, their children had a higher risk of feeding difficulties. Specifically, for parents and grandparents with anxiety symptoms, the ORs of feeding difficulties were 1.84 (95% CI: 1.14-2.98) and 2.17 (95% CI: 1.46-3.22), respectively; for parents and grandparents with depression symptoms, the ORs of feeding difficulties were 2.03 (95% CI: 1.40-2.95) and 1.93 (95% CI: 1.37-2.73), respectively. CONCLUSION Caregivers' anxiety or depression symptoms are positively associated with feeding difficulties in children.

Abstract
Hydrogen is considered as an ideal and sustainable energy carrier because of its high energy density and carbon-free combustion. Electrochemical water splitting is the only solution for uninterrupted, scalable, and sustainable production of hydrogen without carbon emission. However, a large-scale hydrogen production through electrochemical water splitting depends on the availability of earth-abundant electrocatalysts and a suitable electrolyte medium. In this article, we demonstrate that hydrogen evolution reaction (HER) performance of electrocatalytic materials can be controlled by their surface functionalization and selection of a suitable electrolyte solution. Here, we report syntheses of few-layered MoS2 nanosheets, NiO nanoparticles (NPs), and multiwalled carbon nanotubes (MWCNTs) using scalable production methods from earth-abundant materials. Magnetic measurements of as-produced electrocatalyst materials demonstrate that MoS2 nanoflakes are diamagnetic, whereas surface-functionalized MoS2 and its composite with carbon nanotubes have strong ferromagnetism. The HER performance of the few-layered pristine MoS2 nanoflakes, MoS2/NiO NPs, and MoS2/NiO NPs/MWCNT nanocomposite electrocatalysts are studied in acidic and alkaline media. For bare MoS2, the values of overpotential (η10) in alkaline and acidic media are 0.45 and 0.54 V, respectively. Similarly, the values of current density at 0.5 V overpotential are 27 and 6.2 mA/cm2 in alkaline and acidic media, respectively. The surface functionalization acts adversely in the both alkaline and acidic media. MoS2 nanosheets functionalized with NiO NPs also demonstrated excellent performance for oxygen evolution reaction with anodic current of ~60 mA/cm2 and Tafel slope of 78 mVdec-1 in alkaline medium.

Abstract
Objective: To investigate the correlation between gastric bubble size and laryngopharyngeal reflux pattern in patients with laryngopharyngeal reflux disease(LPRD). Methods: A total of 52 LPRD patients who underwent Dx-pH monitoring and anteroposterior chest radiography at the same time from February 2016 to November 2018 were retrospectively studied. Patients were devided into three position-related groups according to the Ryan score of upright and supine: isolated upright reflux(IUR), isolated supine reflux(ISR) and bipositional reflux(BR) groups. In addition, 13 healthy volunteers with negative pH monitoring were selected as the control group. Gastric bubble size and pH monitoring data among the four groups were compared. SPSS 24.0 was used for statistical analysis. Results: In all the 52 patients, 35 cases (67.3%) were classified as IUR, 9 cases (17.3%) as ISR, and 8 cases (15.4%) as BR. The height of gastric bubbles in the four groups were: IUR (26±14) mm, ISR (9±8) mm, BR (20±13) mm, control (17±15) mm, and statistical difference was found among the four groups(P=0.004). Post Hoc Multiple Comparisons found that IUR group had statistical difference between ISR group and control group (P=0.001, P=0.034 respectively). There was no statistical difference of gastric bubble width and area among the four groups(P=0.340, P=0.186 respectively). The ROC curve of the gastric bubble height with isolated upright and supine reflux patterns was obtained, and the optimal cutoff value of the gastric bubble height was 11 mm. Accordingly, we divided the patiens into two groups with high and low gastric bubble. LPRD reflux pattern distribution was significantly different between the two groups(P<0.001). The comparison of reflux parameters in pH monitoring also showed that the supine reflux parameters in the lower group were significantly higher than those in the higher group, and the upright reflux parameters in the higher group were significantly higher than those in the lower group(P<0.001). Conclusions: The height of gastric bubble is significantly correlated with the reflux patterns in LPRD patients. The gastric bubble of patients with IUR is significantly higher than that of patients with ISR. Taking 11 mm as the cutoff value, patients with higher gastric bubble are more prone to upright laryngopharyngeal reflux, while those with lower gastric bubble are more prone to supine laryngopharyngeal reflux.

Abstract
Transforming growth factor-beta (TGF-β) functions in fibrogenesis as a profibrotic mediator, regulating cell proliferation, migration, apoptosis and collagen production of fibroblasts. microRNA-155 (miR-155), the expression of which has been related to bleomycin-induced idiopathic pulmonary fibrosis, has been involved in TGF-β induced epithelial-mesenchymal transition. Here, we found that miR-155 expression was decreased in human pulmonary fibroblasts by TGF-β treatment. We overexpressed miR-155 in fibroblasts to investigate the functional impact of miR-155 on TGF-β-induced fibrotic phenotype of fibroblasts. It is suggested that miR-155 overexpression attenuated the stimulatory effect of TGF-β on fibroblast proliferation, migration and collagen synthesis, by evidence from assessment of cell cycle, viability, apoptosis, migration and collagen content. Furthermore, quantitative measurement showed that SMAD1 gene expression was decreased following miR-155 inhibition, thereby demonstrating an indirect miRNA-SMAD interaction that links miR-155 to TGF-β signaling. Our work helped uncover an miRNA-mediated mechanism of fibroblast response to TGF-β. Moreover, it will help to achieve a better understanding of the regulatory roles of miR-155 in fibrogenesis.

Abstract
Objective: To evaluate the efficacy and prognostic factors in core binding factor (CBF) acute myeloid leukemia (AML) under current therapy modalities, therefore optimizing the treatment strategies. Methods: Standard cytological and immune methods including next generation sequencing (NGS) were used for risk stratification. Complete remission (CR) rate, disease-free survival (DFS) and overall survival (OS) were assessed by multivariate Logistic and Cox regression models in a total of 206 adults (aged 16-65 years) with CBF-AML, including 152 AML patients with t(8;21) and 54 with inv(16). Results: The CR rate of inv(16) patients after first course was 54/54(100%), significantly higher than that of t(8;21) patients [127/147(86.4%), P=0.005]. The fusion transcript level and KIT mutation were independent factors related to CR rate in t(8;21) patients (P=0.044 and 0.027; respectively). DFS and OS in inv(16) patients tended to be more superior than that in t(8;21) patients (P=0.066 for DFS; P=0.306 for OS; respectively). Multivariate Cox identified negative expression of CD(19) and female gender the independent predictors of inferior DFS in t(8;21) patients (P=0.000 for CD(19); P=0.006 for sex; respectively). Analysis of combining CD(19) with gender indicated that females/CD(1)(9-)subpopulation had significantly poor DFS than did males/CD(19)(+) ones (Bonferroni-P<0.000 01). The number of mutations in each patient, FLT3-ITD and additional karyotype abnormalities did not affect CR rate and DFS (all P>0.05). Conclusions: Patients with inv(16) have better induction response than those with t(8;21). High level of fusion transcripts and positive KIT mutation are associated with low CR rate in t(8;21) patients. Negative CD(19) expression and female gender are independent predictors of inferior DFS in t(8;21) patients.

Abstract
Abstract
Background
Pulmonary hypertension (PH) patients have poor prognosis due to progressive right ventricular (RV) dysfunction. As a low-cost and non-invasive tool, echocardiography is by far the most widely used technique to investigate the RV structure and function in PH patients. Recent studies showed that RV longitudinal strain (RVLS) measured by two- or three-dimensional echocardiography (2DE, 3DE) was correlated with RV function parameters and have the potential to predict the prognosis of PH patients. However, few studies have compared the value of 2DE- and 3DE- RVLS to predict disease severity of pre-capillary PH patients. Therefore, our study aims to compare the capacity of RVLS assessed by 3DE and 2DE in predicting disease severity of pre-capillary PH patients.
Methods
We consecutively enrolled 57 patients (18 males and 39 females, 35±13 years) with pre-capillary PH diagnosed by right heart catheterization in our center. Standard transthoracic echocardiography was performed in all participants. 2DE- RVLS were obtained from speckle-tracking analyses using GE EchoPAC version 201; while 3DE- RVLS were analyzed by TomTec 4D RV-Function 2.0. On the basis of the risk assessment strategy of 2015 ESC Guidelines for the diagnosis and treatment of pulmonary hypertension, all the participants were classified into low risk or intermediate-high risk groups. Linear regression analyses were performed to evaluate the correlations between RVLS and peak oxygen consumption (PVO2). In addition, receive operating characteristic curves (ROC) were used to compare the predictive values of 2DE- and 3DE-RVLS and identify the optimal cut points for the detection of low risk based on the risk assessment strategy of 2015 ESC Guidelines.
Results
Linear regression analyses showed a significant correlation between PVO2 and 2DE- RVLS (r=−0.484, P<0.001), while a relatively weaker correlation was observed between PVO2 and 3DE- RVLS (r=−0.299, P=0.024). ROC curve showed 2DE-RVEF had a better capacity to classify pre-capillary PH patients into low or intermediate-high risk groups (2DE- vs 3DE-: AUC=0.78, P=0.003 vs AUC=0.69, P=0.044). Optimal cut-offs found 2DE-RVEF <−13.85% had a 73.3% sensibility and 75.0% specificity to predict low risk.
Conclusions
Both two- and three-dimensional echocardiography detected RVLS had the potential to evaluate disease severity of pre-capillary PH patients, but the former may have a better predictive capacity.

Abstract
We report the first measurement of the double-differential and total muon neutrino charged current inclusive cross sections on argon at a mean neutrino energy of 0.8 GeV. Data were collected using the MicroBooNE liquid argon time projection chamber located in the Fermilab Booster neutrino beam and correspond to 1.6×10^{20} protons on target of exposure. The measured differential cross sections are presented as a function of muon momentum, using multiple Coulomb scattering as a momentum measurement technique, and the muon angle with respect to the beam direction. We compare the measured cross sections to multiple neutrino event generators and find better agreement with those containing more complete treatment of quasielastic scattering processes at low Q^{2}. The total flux integrated cross section is measured to be 0.693±0.010(stat)±0.165(syst)×10^{-38} cm^{2}.

Abstract
We present the results of x-ray scattering and muon-spin relaxation ([Formula: see text]SR) measurements on the iron-pnictide compound FeCrAs. Polarized non-resonant magnetic x-ray scattering results reveal the 120° periodicity expected from the suggested three-fold symmetric, non-collinear antiferromagnetic structure. [Formula: see text]SR measurements indicate a magnetically ordered phase throughout the bulk of the material below [Formula: see text] K. There are signs of fluctuating magnetism in a narrow range of temperatures above [Formula: see text] involving low-energy excitations, while at temperatures well below [Formula: see text] behaviour characteristic of freezing of dynamics is observed, likely reflecting the effect of disorder in our polycrystalline sample. Using density functional theory we propose a distinct muon stopping site in this compound and assess the degree of distortion induced by the implanted muon.

Abstract
目的 探讨淋巴细胞/单核细胞比值(LMR)及2个疗程后PET评价(PET-2)在成人霍奇金淋巴瘤(HL)中的预后价值。 方法 回顾性分析2007年1月至2016年3月南京医科大学第一附属医院133例初诊成人HL患者的临床资料。采用X-tile软件确定变量的最佳临界值,生存分析采用Kaplan-Meier法及Cox回归。 结果 133例HL患者中位年龄33(18~84)岁,男女比例1.9∶1。LMR最佳临界值为2.5,LMR<2.5组无进展生存(PFS)时间(P<0.001)和总生存(OS)时间(P<0.001)均较LMR ≥2.5组显著缩短。多因素生存分析显示LMR<2.5是HL患者PFS(HR=2.35,95%CI 1.36~4.07,P=0.002)和OS(HR=10.36,95%CI 2.35~45.66,P=0.002)的独立预后因素。56例患者的PET-2结果分析显示,PET-2阳性患者PFS明显差于PET-2阴性患者(P=0.022)。根据LMR和PET-2将患者分为PET-2阴性且LMR ≥2.5、PET-2阳性或LMR<2.5、PET-2阳性且LMR<2.5三组,三组间的PFS和OS差异均有统计学意义(P值分别为0.009和0.012)。 结论 LMR<2.5是成人HL患者的独立预后不良因素。PET-2与LMR结合的预后价值可能更好。

Abstract
This meta-analysis aimed to clarify the actual association between the phosphodiesterase type 5 inhibitors (PDE5-Is) use and the risk of melanoma in erectile dysfunction (ED) patients. A systematic literature search was conducted in online databases in October, 2016 to identify studies focusing on the association between PDE5-Is use and the risk of melanoma. Summarized multivariate adjusted risk ratios (RRs) and 95% confidence intervals (CIs) were calculated to assess the strength of associations. A total of six clinical trials containing more than one million participants were included. ED patients using PDE5-Is shared a significant high risk of melanoma (RR=1.12, 95% CI=1.03-1.21, p=0.006). Positive associations were observed in all kinds of prescriptions: single prescription (RR=1.20, 95% CI=1.06-1.35, p=0.003), medium number of prescription (RR=1.15, 95% CI=1.01-1.30, p=0.03), and high number of prescription (RR=1.18, 95% CI=1.05-1.34, P=0.006). Additionally, PDE5-Is were also found to be significantly associated with increased risk of basal cell carcinoma (RR=1.14, 95% CI=1.09-1.19, p<0.00001). Our study indicates that PDE5-Is use could significantly increase the risk of melanoma and basal cell carcinoma. However, the risk of melanoma did not rise significantly with the increased number of prescriptions. Consequently, owing to the lack of information about other potential synergistic factors, it is difficult for us to make a solid conclusion that application of PDE5-Is is the direct cause of increased risk of melanoma. Their relationship needs to be validated by further evidences.

Abstract
In the high luminosity Large Hadron Collider upgrade of the A Toroidal LHC ApparatuS (ATLAS) experiment in 2026, the new inner tracker detector will be installed. As a promising candidate for the outer layer of the inner tracker detector, the High Voltage CMOS (HV-CMOS) pixel sensors are being investigated by the ATLAS collaboration. A Front-End LInk eXchange (FELIX) based Data Acquisition (DAQ) system is developed for the R&D of the HV-CMOS sensors. A FELIX card with a Peripheral Component Interconnect express interface in the back-end is used to control, monitor, calibrate, and read out the front-end electronics. In the front-end, a Xilinx evaluation board ZC706 works as the interface between the back-end and the custom boards with HV-CMOS sensors and the readout Application-Specific Integrated Circuit. The DAQ system was successfully deployed for the testbeam experiment at CERN. The design of the DAQ system, the tuning of sensors, and the testbeam results will be described in details.
