Abstract
Wheat has a large and diverse repertoire of NLRs involved in disease resistance, with over 1500 NLRs detected in some studies. These NLR genes occur as singletons or clusters containing copies of NLRs from different phylogenetic clades. The number of NLRs and cluster size can differ drastically among ecotypes and cultivars. Primarily, duplication has led to the evolution and diversification of NLR genes. Among the various mechanisms, whole genome duplication (WGD) is the most intense and leading cause, contributing to the complex evolutionary history and abundant gene set of hexaploid wheat. Tandem duplication or recombination is another major mechanism of NLR gene expansion in wheat. The diversity and divergence of duplicate NLR genes are responsible for the broad-spectrum resistance of most plant species with limited R genes. Understanding the mechanisms underlying the rapid evolution and diversification of wheat NLR genes will help improve disease resistance in crops. The present review focuses on the diversity and divergence of duplicate NLR genes and their contribution to wheat disease resistance. Moreover, we provide an overview of disease resistance-associated gene duplication and the underlying strategies in wheat.

Abstract
Grain size is a key trait associated with bread wheat yield. It is also the most frequently selected trait during domestication. After the phenotypic characterization of 768 bread wheat accessions in three plots for at least two years, the present study shows that the improved variety showed significantly higher grain size but lower grain protein content than the landrace. Using 55K SNP assay genotyping and large-scale phenotyping population and GWAS data, we identified 5, 6, 6, and 6 QTLs associated with grain length, grain weight, grain area, and thousand grain weight, respectively. Seven of the 23 QTLs showed common association within different locations or years. Most significantly, the key locus associated with grain length, qGL-2D, showed the highest association after years of multi-plot testing. Haplotype and evolution analysis indicated that the superior allele of qGL-2D was mainly hidden in the improved variety rather than in landrace, which may contribute to the significant difference in grain length. A comprehensive analysis of transcriptome and homolog showed that TraesCS2D02G414800 could be the most likely candidate gene for qGL-2D. Overall, this study presents several reliable grain size QTLs and candidate gene for grain length associated with bread wheat yield.

Abstract
Even frequently used in wheat breeding, we still have an insufficient understanding of the biology of the products via distant hybridization. In this study, a transcriptomic analysis was performed for six Triticum aestivum-Thinopyrum elongatum substitution lines in comparison with the host plants. All the six disomic substitution lines showed much stronger "transcriptomic-shock" occurred on alien genomes with 57.43-69.22% genes changed expression level but less on the recipient genome (2.19-8.97%). Genome-wide suppression of alien genes along chromosomes was observed with a high proportion of downregulated genes (39.69-48.21%). Oppositely, the wheat recipient showed genome-wide compensation with more upregulated genes, occurring on all chromosomes but not limited to the homeologous groups. Moreover, strong co-upregulation of the orthologs between wheat and Thinopyrum sub-genomes was enriched in photosynthesis with predicted chloroplastic localization, which indicates that the compensation happened not only on wheat host genomes but also on alien genomes.

Abstract
OBJECTIVE To investigate whether MOTS-c can regulate the synthesis of type I collagen in osteoblasts by regulating TGF-β/SMAD pathway, thereby improving osteoporosis. MATERIALS AND METHODS Viability of hFOB1.19 cells treated with MOTS-c was detected by CCK-8 assay. The mRNA and protein levels of TGF-β, SMAD7, COL1A1 and COL1A2 in hFOB1.19 cells were detected by quantitative Real-time polymerase chain reaction (qRT-PCR) and Western blot, respectively. We then changed expressions of TGF-β and SMAD7 by plasmids transfection to detect levels of COL1A1 and COL1A2 in hFOB1.19 cells by qRT-PCR and Western blot, respectively. RESULTS Cell viability was significantly increased after treatment of 1.0 μM MOTS-c for 24 h or 0.5 μM MOTS-c for 48 h in a time-dependent manner. The mRNA and protein expressions of TGF-β, SMAD7, COL1A1 and COL1A2 in hFOB1.19 cells were dependent on the concentration of MOTS-c. In addition, MOTS-c increased the expressions of COL1A1 and COL1A2, which were partially reversed by knockdown of TGF-β or SMAD7. CONCLUSIONS MOTS-c could promote osteoblasts to synthesize type I collagen via TGF-β/SMAD pathway.

Abstract
OBJECTIVES Tuberculous pleurisy (TP) diagnosis remains difficult, with the sensitivity of Xpert MTB/RIF (Xpert) and mycobacterial culture (culture) only about 30-50%. We aimed to assess the diagnostic performance of a cell-free Mycobacterium tuberculosis DNA test (cf-TB) in pleural effusion for TP. METHODS Adults (≥18 years) with suspected TP presenting with pleural effusion were consecutively recruited, and pleural effusion specimens were prospectively collected in Beijing Chest Hospital, Beijing, China. After centrifuging pleural effusion, sediments were used for culture, Xpert and T-SPOT.TB assay, whereas supernatants were used for cf-TB and adenosine deaminase assay. The diagnostic performance was assessed against a composite reference standard. RESULTS From June 2015 to December 2018, we prospectively evaluated 286 adults with suspected TP. One hundred twenty-two participants were classified as definite TP based on the prespecified composite reference standard. The cf-TB produced a sensitivity of 79.5% (97/122, 95% confidence interval (CI) 72.4- 86.7) for definite TP, which was superior to Xpert (38.5% (29.9-47.2); 47/122; p < 0.001) and culture (27.1% (19.2-34.9); 33/122; p < 0.001). With pleural effusion Xpert and/or culture as the reference standard, cf-TB showed 96.6% (57/59, 95% CI 92.0-100.0) sensitivity, which was also significantly higher than Xpert (79.7%, 95% CI 69.4-89.9; 47/59; p 0.004) and culture (55.9%, 95% CI: 43.3-68.6; 33/59; p < 0.001). CONCLUSIONS The cf-TB clearly showed improved sensitivity compared with Xpert and culture. We recommend cf-TB as the first-line test for TP diagnosis.

Abstract
Microbiome modulators such as probiotics are known to modulate oral diseases. Very few probiotics are commercially available for use in the oral cavity. In this context, we selected human-origin Lactobacillus salivarius AR809 as a promising oropharyngeal probiotic and characterized its functional and immunomodulatory properties. Results demonstrated that AR809 could efficiently adhere to pharyngeal epithelial FaDu cells, antagonize Staphylococcus aureus, adapt to the oral environment, and modulate host innate immunity by inducing potentially protective effects. Particularly, AR809 diminished proinflammatory activity by enhancing the production of IL10 and inhibiting the expression of tumor necrosis factor-α, IL1B, inducible nitric oxide synthase, and RELA. Finally, we observed that AR809 grew efficiently when cultured in milk, suggesting that the preparation of a fermented milk product containing AR809 could be a practical way to administer this probiotic to humans. In conclusion, AR809 has high potential to adhere to the pharyngeal mucosa and could be applied in novel milk-based probiotic fermented food products.

Abstract
Human oral microbiota is the ecological community of commensal, symbiotic, and pathogenic microorganisms found in the oral cavity. Oral microbiota generally exists in the form of a biofilm and plays a crucial role in maintaining oral homeostasis, protecting the oral cavity and preventing disease development. Human oral microbiota has recently become a new focus research for promoting the progress of disease diagnosis, assisting disease treatment, and developing personalised medicines. In this review, the scientific evidence supporting the association that endogenous and exogenous factors (diet, smoking, drinking, socioeconomic status, antibiotics use and pregnancy) modulate oral microbiota. It provides insights into the mechanistic role in which oral microbiota may influence systemic diseases, and summarises the challenges of clinical diagnosis and treatment based on the microbial community information. It provides information for noninvasive diagnosis and helps develop a new paradigm of personalised medicine. All these benefit human health in the post-metagenomics era.

Abstract
Objective: To explore the therapeutic effects of dendritic cells (DC) modified by the dust-mite-allergen(Der p1) gene on mouse model of allergic rhinitis (AR). Methods: DC modified by the Der p1 gene (Der p1-DC) were prepared.Using random number table, 24 Balb\c mice were divided into four groups: immature DC (imDC)/AR group, dexamethasone/AR group, Der p1-DC/AR group and control group, with 6 mice in each group.AR mouse model was built with Der p1 and the mouse model of AR was established.The AR mice were respectively given by abdominal injection of Der p1-DC, imDC and dexamethasone.Normal control mice were treated with physiologic saline.ELISA method was used for determining the content of IgE, IgG1and histamine in blood.The relative expression of mRNA of IL-4 and IL-13 on nasal mucosa with protein was analyzed by RT-PCR and Westen blot methods.All the data were statistically analyzed by SPSS 19.0 statistical software, and the variance analysis was used in multiple groups of average samples. Results: The contents of IgE, IgG1 and histamine in the mice of Der p1-DC/AR group were lower than those in imDC/AR group ((0.560±0.110) OD 450 nm vs (1.150±0.280) OD 450 nm, (0.690±0.054) OD 450 nm vs (0.920±0.125) OD 450 nm, (4 145±670) pg/ml vs (7 685±669) pg/ml, t value was 4.80, 4.14, 9.16, respectively, all P<0.05), and the expression of IL-4 and IL-13 on nasal mucosa in Der p1-DC/AR group was remarkedly lower than those in imDC/AR group (0.41±0.25 vs 1.59±1.02, 0.26±0.01 vs 1.10±0.09, t value was 2.75, 22.72, respectively, all P<0.05). There was no statistically significant difference between the mice treated with Der p1-DC and dexamethasone group. Conclusions: The results showed that Der p1-DC could reduce inflammation in AR mice and decrease the expression of IL-4 and IL-13. It suggested that Der p1-DC can be used in the immunotherapy of AR mouse.

Abstract
Objective: To explore the effect of hydrogen-rich saline on the CD4(+) CD25(+) Foxp3(+) Treg cells in a guinea pig model of allergic rhinitis (AR) and investigate the underling anti-inflammatory mechanism. Methods: Using random number table, eighteen guinea pigs were divided into three groups (control group/AR group/HRS group, n=6 of each group). AR guinea pig model was built with ovalbumin and aluminum. The guinea pigs were injected with hydrogen-rich saline (HRS group) for ten days after sensitation. And control group was injected with equal normal saline at the same time. Number of sneezes, degree of runny nose and nasal rubbing movements were scored. Peripheral blood eosinophil count was recorded. The content of interleukin 10(IL-10) and transforming growth factor β (TGF-β) in the serum were detected by enzyme-linked immunosorbent assay (ELISA). Immunohistochemical method was taken to detect IL-10 and TGF-β in nasal mucosa. The proportion of CD4(+) CD25(+) Foxp3(+) T cells in the CD4(+) T cells of spleen and peripheral blood were determined with flow cytometry. SPSS 17.0 software was used to analyze the data. Results: There was significant difference in symptom scores among them. The scores of AR group preceded control group, and HRS could decrease the scores of AR ((6.29±1.79) vs (1.01±0.71), (4.50±0.84) vs (6.29±1.79), F=24.725, all P<0.05). The highest number of eosinophils in the peripheral blood belonged to control group, and the number of eosinophils were dramatically reduced after HRS administration ((0.41±0.05)×10(9)/L vs (0.25±0.03 )×10(9)/L, (0.32±0.03)×10(9)/L vs (0.41±0.05)×10(9)/L, F=70.05, all P<0.05). The content of IL-10 and TGF-β in control group is peak ((86.88±17.17) pg/ml, (598.28±72.70) pg/ml, respectively), and compared with AR group, HRS also increased the expression of IL-10 and TGF-β of peripheral blood ((72.54±11.75) pg/ml vs (53.49±10.07) pg/ml, (530.23±57.15) pg/ml vs (482.69±65.96) pg/ml, F value was 28.357, 14.128, respectively, all P<0.05). The proportion of CD4(+) CD25(+) Foxp3(+) Treg cells in controls exceeded HRS group and AR group (1.81%±0.10%, 1.29%±0.74%, respectively), and HRS treatment increased the ratio of CD4(+) CD25(+) Foxp3(+) Treg cells than AR group of peripheral blood ((1.50%±0.11%) vs (1.15%±0.11%), F=168.96, P<0.05). But there was no significant diferences in splene tissue ((1.01%±0.08%) vs (0.98%±0.09%), F=97.381, P>0.05). Conclusion: Both the number and the cytokine secretion of CD4(+) CD25(+) Foxp3(+) Treg cells are decreased in AR group, HRS may inhibit inflammatory response and ameliorate AR via improving the number and the cytokine secretion.

Abstract
Autologous hematopoietic stem cell (HSC) and mesenchymal stem cell (MSC) transplantation is currently being evaluated as a novel treatment for autoimmune diseases, such as systemic lupus erythematosus (SLE). Here we report a case of autologous HSC transplantation combined with MSCs in a 25-year-old severe SLE patient with multiple life-threatening complications and refractory to conventional cyclophosphamide (CYC) therapy. After being pretreated with CYC, fludarabine and antithymocyte globulin, the patient was transplanted with autologous CD34+HSCs and MSCs by intravenous infusion. Hematopoietic regeneration was observed on day 12 thereafter. After HSC and MSC transplantation, the patient's clinical symptoms caused by SLE were remitted, and the SLEDAI score decreased. Moreover, CD4+CD25+FoxP3+Treg cells increased in peripheral blood mononuclear cells (PBMCs) after transplantation. This result suggests that the combined transplantation of HSCs and MSCs may reset the adaptive immune system to re-establish self-tolerance in SLE. A 36-month follow-up showed that the clinical symptoms remained in remission. Although a longer follow-up is required for assessing the long-term efficacy, our present results suggest that the combined transplantation of HSCs and MSCs may be a novel and effective therapy for refractory SLE.

Abstract
Two procedures are used to establish calibration of the visible and near-infrared channels of the National Oceanic and Atmospheric Administration-11 (NOAA-II) Advanced Very High Resolution Radiometer (AVHRR). The first procedure for visible spectra, uses satellite data, ground measurements of atmospheric conditions during satellite overpass, and historical surface reflectance values at White Sands Missile Range (WSMR) in New Mexico. The second procedure, for the near-infrared, uses knowledge of the reflective properties at the WSMR and of a low-reflectance area, as determined from the first method, that yields satellite-gain values without a requirement for ground measurements of atmospheric conditions. The accuracy of gain values is estimated at ±7% for the two methods. The WSMR combines accessibility, a wide range of surface reflectances, and generally good observing conditions, making it a desirable location for satellite calibration.
