Abstract
The intensely studied white gene is widely used as a genetic marker in Drosophila melanogaster. Here, we cloned and characterized the white gene in an important pest of the fruit industry, Bactrocera dorsalis, to understand its functional role in pigmentation. We obtained BdWhite knockout strains, based on the wild-type strain, using the CRISPR/Cas9 genome editing system, and found that mutants lost pigmentation in the compound eye and their black head spots. We then examined differences in the expression levels of genes associated with melanin pigmentation between mutants and the wild-type strain using quantitative reverse transcription PCR. We found that transcription levels of the Bd-yellow1 were lower in the head of mutants than in the wild-type strain, and there were no significant differences in expression of the other six genes between mutants and the wild type. Since yellow is critical for melanin biosynthesis (Heinze et al., Scientific Reports. 2017;7:4582), the lower levels of expression of Bd-yellow1 in mutants led to reduced dark pigmentation in head spots. Our results provide the first evidence, to our knowledge, that white may play a functional role in cuticle pigmentation by affecting the expression of yellow.

Abstract
The first measurement of the ϒ(1S) elliptic flow coefficient (v_{2}) is performed at forward rapidity (2.5<y<4) in Pb-Pb collisions at sqrt[s_{NN}]=5.02 TeV with the ALICE detector at the LHC. The results are obtained with the scalar product method and are reported as a function of transverse momentum (p_{T}) up to 15 GeV/c in the 5%-60% centrality interval. The measured ϒ(1S)v_{2} is consistent with 0 and with the small positive values predicted by transport models within uncertainties. The v_{2} coefficient in 2<p_{T}<15 GeV/c is lower than that of inclusive J/ψ mesons in the same p_{T} interval by 2.6 standard deviations. These results, combined with earlier suppression measurements, are in agreement with a scenario in which the ϒ(1S) production in Pb-Pb collisions at LHC energies is dominated by dissociation limited to the early stage of the collision, whereas in the J/ψ case there is substantial experimental evidence of an additional regeneration component.

Abstract
Elastic electron-proton scattering (e-p) and the spectroscopy of hydrogen atoms are the two methods traditionally used to determine the proton charge radius, rp. In 2010, a new method using muonic hydrogen atoms1 found a substantial discrepancy compared with previous results2, which became known as the 'proton radius puzzle'. Despite experimental and theoretical efforts, the puzzle remains unresolved. In fact, there is a discrepancy between the two most recent spectroscopic measurements conducted on ordinary hydrogen3,4. Here we report on the proton charge radius experiment at Jefferson Laboratory (PRad), a high-precision e-p experiment that was established after the discrepancy was identified. We used a magnetic-spectrometer-free method along with a windowless hydrogen gas target, which overcame several limitations of previous e-p experiments and enabled measurements at very small forward-scattering angles. Our result, rp = 0.831 ± 0.007stat ± 0.012syst femtometres, is smaller than the most recent high-precision e-p measurement5 and 2.7 standard deviations smaller than the average of all e-p experimental results6. The smaller rp we have now measured supports the value found by two previous muonic hydrogen experiments1,7. In addition, our finding agrees with the revised value (announced in 2019) for the Rydberg constant8-one of the most accurately evaluated fundamental constants in physics.

Abstract
Chronic excess alcohol intake triggers the formation of enterogenic endotoxemia. TLR4 ligand localization activates nuclear transcription factor NF-κB by inducing the up-regulation of NLRP3 inflammasome and the biologically inactive IL-1β and IL-18 precursors to form initiation of pro-inflammatory signals. Under the influence of ethanol, the damaged hepatocyte release uric acid, and adenosine triphosphate and induces NLRP3 inflammasome assembly and functional activation in Kupffer cells to promote the release of inflammatory mediators, such as interleukin-1β and interleukin-18, that cascade mediates inflammation and drive alcoholic liver disease from steatosis to inflammation and fibrosis. The NLRP3 inflammasome acts as a ligand-sensing element and plays an important role in mediating the immune and inflammatory response in the course of alcoholic liver disease. Thus, exploring the activation mechanism of NLRP3 inflammasome and its pathogenic role may provide a new idea in the clinical treatment of alcoholic liver disease.

Abstract
Thymosin beta 10 (Tβ10) is a member of the β-thymosin family. As an actin-binding peptide, thymosin β10 is involved in many important biological activities. Transcriptome sequencing results suggest that Tβ10 may play important roles in the growth of deer antler. In this study, Tβ10 cDNA was isolated from sika deer, and complete open reading frame consisting of 129 nucleotides was obtained by PCR amplification. The predicted peptide was 42 amino acids in length. The sdTβ10 cDNA was cloned and expressed in Escherichia coli resulting in a 6 kDa recombinant-His tagged protein. The recombinant, non-glycosylated peptide was overexpressed in a soluble form and purified by immobilized metal ion affinity chromatography. Functional studies revealed that recombinant Tβ10 stimulated osteoblasts proliferation. This study provides the first evidence that recombinant sika deer Tβ10 promotes proliferation in an osteoblasts cell model.

Abstract
OBJECTIVE To study fractional exhaled nitric oxide (FeNO) levels among pre-school children in day care centres (DCCs) in relation to indoor and outdoor air pollution in northern China. DESIGN This was a cross-sectional study among children aged 5 years from 34 classrooms at 10 randomly selected DCCs in Taiyuan, China. A total of 507 (99%) children participated. Air pollution and carbon dioxide (CO2) levels were measured in the classroom and outside the school. Linear mixed models were applied for statistical analysis. RESULTS The geometric mean FeNO was 9.1 ± 1.5 parts per billion; 11.6% of children had wheeze, 6.0% had dry cough, 26.4% rhinitis symptoms, 1.6% ever physician-diagnosed asthma and 29.2% ever physician-diagnosed pneumonia. FeNO levels were associated with current wheeze (P = 0.04) and ever physician-diagnosed pneumonia (P = 0.05). The mean indoor concentrations were particulate matter with a diameter of <2.5 μm (PM2.5) 268 μg/m3, sulfur dioxide (SO2) 40.5 μg/m3, nitrogen dioxide (NO2) 43.0 μg/m3 and CO2 827 parts per million. Outdoor concentrations were PM2.5 244 μg/m3, SO2 106.6 μg/m3 and NO2 40.9 μg/m3. PM2.5 levels inside (P = 0.002) and outside DCCs (P = 0.05) were associated with FeNO levels. CONCLUSION PM2.5 levels inside and outside DCCs in China can contribute to airway inflammation in pre-school children. Children with current wheeze and ever physician-diagnosed pneumonia may have higher FeNO levels.

Abstract
Objective: To analyze MRI findings of hypovascular clear cell renal cell carcinoma. Methods: The clinical data and MRI findings of patients with hypovascular clear cell RCC confirmed by pathology from February 2016 to March 2017 were retrospectively analyzed in General Hospital of Chinese People's Liberation Army. According to the diameter of the lesions, they were divided into two groups of diameter ≤4 cm and group of diameter > 4 cm. The data was analyzed by using χ(2) to compare clinical data and tumor imaging characteristics between the two groups. Results: Thirty-four patients had 34 hypovascular lesions.The solid part of the tumor showed a slightly hypo- and isointense in 31 lesions, and high signal in 3 lesions; T(1)WI showed slightly lower and equal signal in 29 lesions and high signal in 5 lesions; DWI showed equal low signal in 10 lesions, 24 tumors were mainly high signal; 33 lesions showed pseudo-capsule; tumor hemorrhage in 12 lesions, necrosis in 9 lesions and cystic change in 22 lesions, lipid component in 4 lesions. There were 19 lesions with diameter ≤ 4 cm and 15 lesions with diameter > 4 cm. The surgical methods and bleeding in the lesion were statistically different between the two groups (P<0.05). Conclusion: The MRI findings of hypovascular clear cell RCC are low signal on T(2)WI, high signal on DWI mainly, less lipid. Laparoscopic radical resection was more suitable for lesions with diameter >4 cm and these lesions were more likely to bleed within the tumor.

Abstract
Objective: To investigate the predictive value of multimode MRI features for nuclear grade of clear cell renal cell carcinoma (ccRCC). Methods: From January 2016 to October 2017, 381 patients (387 tumors) with ccRCC proven by pathology in Chinese PLA General Hospital First Medical Center were enrolled (male 293, female 88, age 24-87 years old). The clinical and imaging data of these patients were retrospectively analyzed, including clinical information (gender, age, BMI, smoke, hypertension) and preoperative renal MRI. Pre-and post-contrast MRI features were subjectively scored. The largest diameter of each lesion was measured. Two-sample t-test,Chi-squared test and binuary Logistic regression analysis were used to evaluate the predictive efficacy of clinical and MRI data. Results: According to WHO/ISUP nuclear grade system,all ccRCCs (n=387) were divided into low grade (n=322) and high grade group (n=65). Between two groups, there were significant differences in age and diameter((54±12) vs (59±10) years old, P=0.001; (4.1±2.2) vs (6.2±3.0) cm, P<0.01). In MRI scores,there were significant differences in scores of pseudocapsule, shape and margin,hemorrhage,enhancement degree,cystic-solid,intratumoral vessel,peritumoral vessel, renal sinus invasion, vein thrombosis, lymphadenopathy, necrosis, perinephric invasion and metastasis, DWI signal intensity between high grade group and low grade group (all P<0.01). Binuary Logistic regression analysis showed that shape and margin, enhancement degree and DWI signal intensity were independent predictors for high grade ccRCC (OR=0.181, 95%CI 0.049-0.666; OR=0.393, 95%CI 0.182-0.846; OR=0.336, 95%CI 0.155-0.728). A nomogram model for predicting the risk of high grade ccRCC was constructed. Conclusions: Multimode MRI features can differentiate low grade and high grade ccRCC. The nomogram developed in this study might aid urologist in the pre-operative prediction of nuclear grade of ccRCC,which might contribute to developing treatment strategy.

Abstract
Objective: To explore the patient and hospital related determinants of adherence to early antithrombotic therapy among patients with acute ischemic stroke (AIS). Methods: AIS patients aged 50 years old or above who were eligible for early antithrombotic therapy, were included from the China National Stroke Registry Ⅱ (CNSR Ⅱ) project. Characteristics related to patients and hospitals were collected. Univariate analysis method was conducted to explore the correlation between hospital or patient-related determinants and early antithrombotic therapy. A 2-level logistic regression model was set up to identify patient and hospital-related variables that were associated with the adherence to early antithrombotic therapy, with patient as level 1 and hospital as level 2. Results: A total of 16 910 patients were included in the study, with 14 332 (84.75%) of them having received early antithrombotic therapy. Results from the univariate analysis showed that the patient determinants to early antithrombotic therapy would include age, type of health insurance, average income and history of dyslipidemia. Hospital determinants would include factors as: level and region of the hospital, academic status, with/without stroke unit, quality control on single disease and the percentage of neurological beds in total beds (P<0.05). Data on multilevel model showed that the patient-related determinants on early antithrombotic therapy would include age, gender, average income, history of hypertension, National Institutes of Health Stroke Scale (NIHSS) score at admission while hospital related determinants would include percentage of neurological beds in total beds, and region of the hospital (P<0.05). Conclusions: The quality of a hospital was associated with the adherence to early antithrombotic therapy. AIS patients at advanced age or with high NIHSS score at admission should be paid more attention.

Abstract
Objective: To investigate the clinical and laboratory features of Phytosterolemia with hematological abnormalities. Methods: A retrospective study was performed on 20 patients with phytosterolemia admitted to the hematology department of the First Affiliated Hospital of Suzhou University during 2004-2017. History of patients was collected and the platelet counts, lipidomic analysis of plasma and osmotic fragility of erythrocytes were carried out. The erythrocyte and platelet morphology was examined by light microscope. Phytosterol levels in serum were measured by high performance liquid chromatography method. All of ABCG5/8 exons and intron-exon boundaries were amplified by PCR and directly sequenced to identify mutations. Results: All patients had been misdiagnosed as immune thrombocytopenia (ITP), or Evans syndrome with a mean delay of 21 years between symptom onset and accuracy diagnosis. The clinical manifestations of the patients were variable, but most of them presented with thrombocytopenia, anemia, splenomegaly from early ages, and xanthomas. Other major features were also observed, such as impaired liver functions (9 cases), premature atherosclerosis (5 cases) and/or arthritis (4 cases). Interestingly, all patients displayed an increased osmotic fragility of red cells and unique blood film features: large unequal platelets surrounded by a circle of vacuoles and various abnormal erythrocyte shapes, especially stomatocyte. Serum levels of the sitosterol and stigmasterol in the patients were remarkably elevated up to 331.05(276.00, 670.20)mg/L and 244.60(193.78,399.40)mg/L, about 10 and 24 times higher than those of normal subjects. There were 14 mutations in ABCG5/8 genes found in the patients. Among them, 2/3 of the mutations were in ABCG5 gene, including p.(E22X), p.(R446X),g.ISV7+3G>A, p.(R446X), p.(R419H), g.ISV7+3G>A, p.(G90E), p.(R389H) and g.7+2G>A), and 1/3 in ABCG8 gene involving p.(M614-K628del), p.(E25X), p.(L86P fs X185), p.(R263Q), p.(E500D fs X604) and p.(G674R) mutation. The ABCG5 p.(R446X) mutation was found in 3 separate families. Conclusions: The phenomena of thrombocytopenia/ stomatocyte/splenomegaly represents a special clinical manifestations of phytosterolemia, and distinct changes of blood cell morphology are the typical characters. Plasma plant sterols and ABCG5/ABCG8 genes should be analyzed when such hematologic abnormalities are unexplained.

Abstract
The first (v_{1}^{fluc}), second (v_{2}), and third (v_{3}) harmonic coefficients of the azimuthal particle distribution at midrapidity are extracted for charged hadrons and studied as a function of transverse momentum (p_{T}) and mean charged particle multiplicity density ⟨N_{ch}⟩ in U+U (sqrt[s_{NN}]=193 GeV), Au+Au, Cu+Au, Cu+Cu, d+Au, and p+Au collisions at sqrt[s_{NN}]=200 GeV with the STAR detector. For the same ⟨N_{ch}⟩, the v_{1}^{fluc} and v_{3} coefficients are observed to be independent of the collision system, while v_{2} exhibits such a scaling only when normalized by the initial-state eccentricity (ϵ_{2}). The data also show that ln(v_{2}/ϵ_{2}) scales linearly with ⟨N_{ch}⟩^{-1/3}. These measurements provide insight into initial-geometry fluctuations and the role of viscous hydrodynamic attenuation on v_{n} from small to large collision systems.

Abstract
BRAF inhibitors substantially have impressive clinical efficacy in cutaneous melanoma. However, their role in acral and mucosal melanoma remains unclear. Records were reviewed of patients with metastatic or unresectable BRAF-mutant acral and mucosal melanoma hospitalized and administrated BRAF inhibitors during January 2011 and March 2016. Clinical data were collected to determine PFS, ORR, DCR, OS, and safety. Among 28 acral and 12 mucosal melanoma patients treated with BRAF inhibitors, median PFS were 3.6 (95%CI 3.0-6.4) and 4.4 (95%CI 0.8-12.7) months, median OS were 6.2 (95%CI 6.1-12.1) and 8.2 (95%CI 6.6-19.9) months; ORRs were 38.1% and 20.0%, DCRs were 81.0% and 70.0% in acral and mucosal melanoma, respectively. BRAF inhibitors were well tolerated. The most common adverse effects (AEs) were cutaneous and hematological. Grade 3/4 AEs were relatively rare. In conclusion, BRAF inhibitors have acceptable efficacy and good tolerance in BRAF mutant acral and mucosal melanoma.

Abstract
Osteocalcin is a major non-collagenous component of the bone extracellular matrix and is considered to be an indicative factor of osteoblast differentiation. In the present study, we detected osteocalcin expression in different antler areas and growth phases by immunohisto- chemistry. Osteocalcin was highly expressed in all areas during the mineralization period and in mesenchymal cell and chondrocyte areas during the rapid growth period. The nucleotide sequence of the osteocalcin gene in sika deer antler was determined. The open reading frame was 303 bp encoding a protein of 100 amino acids. The estimated molecular mass of osteocalcin was 10.38 kDa and the theoretical isoelectric point was 5.37. The osteocalcin gene with a 6× His-tag at the C-terminus was cloned into the pGEX-4T1 vector and expressed in Escherichia coli under optimal conditions. The recombinant soluble protein fused with GST was purified with Ni-NTA resin. The purified osteocalcin protein exhibited a significant increase in HA adhesion and promoted antler chondrocyte proliferation. Osteocalcin is an important factor in regulating the rapid growth and differentiation of deer antlers.

Abstract
The scattering of dark matter (DM) particles with sub-GeV masses off nuclei is difficult to detect using liquid xenon-based DM search instruments because the energy transfer during nuclear recoils is smaller than the typical detector threshold. However, the tree-level DM-nucleus scattering diagram can be accompanied by simultaneous emission of a bremsstrahlung photon or a so-called "Migdal" electron. These provide an electron recoil component to the experimental signature at higher energies than the corresponding nuclear recoil. The presence of this signature allows liquid xenon detectors to use both the scintillation and the ionization signals in the analysis where the nuclear recoil signal would not be otherwise visible. We report constraints on spin-independent DM-nucleon scattering for DM particles with masses of 0.4-5 GeV/c^{2} using 1.4×10^{4} kg day of search exposure from the 2013 data from the Large Underground Xenon (LUX) experiment for four different classes of mediators. This analysis extends the reach of liquid xenon-based DM search instruments to lower DM masses than has been achieved previously.

Abstract
We report a comprehensive inelastic neutron-scattering study of the frustrated pyrochlore antiferromagnet MgCr_{2}O_{4} in its cooperative paramagnetic regime. Theoretical modeling yields a microscopic Heisenberg model with exchange interactions up to third-nearest neighbors, which quantitatively explains all of the details of the dynamic magnetic response. Our work demonstrates that the magnetic excitations in paramagnetic MgCr_{2}O_{4} are faithfully represented in the entire Brillouin zone by a theory of magnons propagating in a highly correlated paramagnetic background. Our results also suggest that MgCr_{2}O_{4} is proximate to a spiral spin-liquid phase distinct from the Coulomb phase, which has implications for the magnetostructural phase transition in MgCr_{2}O_{4}.

Development of a multiplex PCR assay based on the pilA gene sequences to detect different types of Acidovorax citrulli. J Microbiol Methods 2019; 158:93-98.

Abstract
Bacterial fruit blotch (BFB) of cucurbits, caused by Acidovorax citrulli, is a major threat to commercial watermelon and melon production worldwide. At present, there are at least two genetically distinct sub-populations (group I and II) of A. citrulli that differ in host preference among cucurbit species and copper sensitivity. In this study, we analyzed the pilA gene sequences of 103 A. citrulli strains from China and other countries. Based on these data, we classified all tested A. citrulli strains into three types. The pilA-based type 1 strains in this study coincided with the previously established group I strains; while the type 2 strains coincided with group II strains. Ten strains that did not cluster with group I or II strains were classified into a new type, designated type 3. Based on differences in pilA sequences, we designed a multiplex PCR assay to distinguish the three A. citrulli pilus types. This multiplex PCR assay has proven to be viable for strain typing of 139 A. citrulli strains and for the detection of this pathogen in artificially inoculated seeds and leaves and naturally infected leaves and fruits. This assay proved to be rapid, accurate, reliable and applicable for early distinction of A. citrulli types associated with BFB epidemics. It may also inform the judicious and environmentally sound use of bactericides, especially copper-based compounds.
