Abstract
Peripartal cows mobilize not only body fat but also body protein to satisfy their energy requirements. The objective of this study was to determine the effect of prepartum BCS on blood biomarkers related to energy and nitrogen metabolism, and mRNA and protein abundance associated with AA metabolism and insulin signaling in subcutaneous adipose tissue (SAT) in peripartal cows. Twenty-two multiparous Holstein cows were retrospectively classified into a high BCS (HBCS; n = 11, BCS ≥ 3.5) or normal BCS (NBCS; n = 11, BCS ≤ 3.17) group at d 28 before expected parturition. Cows were fed the same diet as a total mixed ration before parturition and were fed the same lactation diet postpartum. Blood samples collected at -10, 7, 15, and 30 d relative to parturition were used for analyses of biomarkers associated with energy and nitrogen metabolism. Biopsies of SAT harvested at -15, 7, and 30 d relative to parturition were used for mRNA (real time-PCR) and protein abundance (Western blotting) assays. Data were subjected to ANOVA using the MIXED procedure of SAS (v. 9.4; SAS Institute Inc., Cary, NC), with P ≤ 0.05 being the threshold for significance. Cows in HBCS had greater overall plasma nonesterified fatty acid concentrations, due to marked increases at 7 and 15 d postpartum. This response was similar (BCS × Day effect) to protein abundance of phosphorylated (p) protein kinase B (p-AKT), the insulin-induced glucose transporter (SLC2A4), and the sodium-coupled neutral AA transporter (SLC38A1). Abundance of these proteins was lower at -15 d compared with NBCS cows, and either increased (SLC2A4, SLC38A1) or did not change (p-AKT) at 7 d postpartum in HBCS. Unlike protein abundance, however, overall mRNA abundances of the high-affinity cationic (SLC7A1), proton-coupled (SLC36A1), and sodium-coupled amino acid transporters (SLC38A2) were greater in HBCS than NBCS cows, due to upregulation in the postpartum phase. Those responses were similar to protein abundance of p-mTOR, which increased (BCS × Day effect) at 7 d in HBCS compared with NBCS cows. mRNA abundance of argininosuccinate lyase (ASL) and arginase 1 (ARG1) also was greater overall in HBCS cows. Together, these responses suggested impaired insulin signaling, coupled with greater postpartum AA transport rate and urea cycle activity in SAT of HBCS cows. An in vitro study using adipocyte and macrophage cocultures stimulated with various concentrations of fatty acids could provide some insights into the role of immune cells in modulating adipose tissue immunometabolic status, including insulin resistance and AA metabolism.

Abstract
Objective: To analyze the clinical characteristics of the severe or critically ill patients with novel coronavirus pneumonia (COVID-19), and evaluate the impact of complicated myocardial injury on the prognosis of these patients. Methods: A retrospective study was conducted in 54 patients who admitted to Tongji hospital from February 3, 2020 to February 24, 2020 and met the criteria of severe or critical conditions of COVID-19. The clinical characteristics and hospital mortality rate were analyzed and compared between the patients with or without myocardial injury, which was defined with 3 times higher serum cardiac troponin value. Results: The age of the 54 patients was 68.0(59.8, 74.3) years. Among all the patients, 24 (44.4%) patients were complicated with hypertension, 13 (24.1%) with diabetes, 8 (14.8%) with coronary heart disease, and 3 (5.6%) with previous cerebral infarction. During hospitalization, 24 (44.4%) of the patients were complicated with myocardial injury and 26 (48.1%) patients died in hospital. In-hospital mortality was significantly higher in patients with myocardial injury than in patients without myocardial injury (14 (60.9%) vs. 8 (25.8%), P=0.013). Moreover, the levels of C-reactive protein (153.6 (80.3, 240.7) ng/L vs. 49.8 (15.9, 101.9) ng/L) and N-terminal pro-B-type natriuretic peptide (852.0 (400.0, 2 315.3) ng/L vs. 197.0 (115.3, 631.0) ng/L) were significantly higher than patients without myocardial injury (all P<0.01). Conclusions: Prevalence of myocardial injury is high among severe or critically ill COVID-19 patients. Severe or critically ill COVID-19 patients with myocardial injury face a significantly higher risk of in-hospital mortality. The study suggests that it is important to monitor and manage the myocardial injury during hospitalization for severe or critically ill COVID-19 patients.

Abstract
Objective: Erosion healing in rheumatoid arthritis (RA) is difficult to demonstrate. This extension study aimed to determine whether 2 years of teriparatide (TPTD) produces erosion healing. Method: Subjects in a previous 12 month randomized controlled trial of TPTD in RA were invited to receive 12 additional months of open-label TPTD. Eleven of the 24 original subjects were enrolled in the extension study, six of whom received TPTD in the final 12 months only. Subjects receiving 24 months of TPTD were assessed for reduction in erosion volume from baseline using computed tomography. We also compared erosion volumes between 12 and 24 months of TPTD. Large erosions in subjects receiving TPTD for 24 months were examined for volume change. Results: In the six patients who received 24 months of TPTD, there was no significant change in erosion volume at the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints compared with baseline. The six subjects who received 24 months of TPTD had similar changes in erosion volume to the five who received 12 months of TPTD, in MCP (p = 0.17) and PIP (p = 0.63) joints. Assessment of large erosions in those receiving TPTD for 24 months showed no evidence of erosion healing. Conclusion: While this extension study was too small to be conclusive, we observed no evidence of reduction in erosion volume with the addition of TPTD for 24 months in subjects with RA in whom disease activity was controlled on a tumour necrosis factor inhibitor. This is consistent with our negative findings at 12 months.

Abstract
Ruminiclostridium papyrosolvens is a promising candidate for producing renewable green chemicals from cellulose due to its cellulolytic and ethanologenic capabilities. It is of significance to screen effective, and convenient-to-use inducible promoters that can be used for regulating the gene expression in R. papyrosolvens. We characterized two endogenous inducible promoters and investigated another two exogenous ones on the adaptability in R. papyrosolvens. Both of the endogenous xylan-inducible promoter Pxyl and exogenous lactose-inducible promoter Plac are found of high specificity and stringency. Pxyl has a short time to be induced while Plac has a low concentration of inducer. With these findings, a mazF-based counter selectable system has been constructed for promoting the efficiency of mutant screening via plasmid curing. The inducible gene expression systems provided novel tools for enhancing the capability of genetic manipulation in engineering R. papyrosolvens. SIGNIFICANCE AND IMPACT OF THE STUDY: Four inducible promoters from Clostridia were characterized in R. papyrosolvens. Xylan-inducible promoter Pxyl was found of a short time while lactose-inducible promoter Plac needs a low concentration of inducer to induce. Employing them, we successfully construct a mazF-based counter selectable system, which would be used to increase the mutant screening efficiency via induction of plasmid curing. The inducible gene expression systems provided novel tools for enhancing the capability of genetic manipulation in engineering R. papyrosolvens.

Abstract
OBJECTIVE To investigate the drug-resistant gene polymorphisms in Plasmodium falciparum imported from Equatorial Guinea to Shandong Province. METHODS From 2015 to 2016, blood samples were collected from imported P. falciparum malaria patients returning from Equatorial Guinea to Shandong Province, and genome DNA of the malaria parasite was extracted. The drug-resistant Pfcrt, Pfmdr1, Pfdhfr, Pfdhps, and K13 genes of P. falciparum were amplified using a PCR assay, followed by DNA sequencing, and the sequences were aligned. RESULTS The target fragments of all 5 drug-resistant genes of P. falciparum were successfully amplified and sequenced. There were 72.8%, 18.6%, and 8.6% of P. falciparum parasites carrying the wild-, mutant-, and mixed-type Pfcrt gene, respectively, and all mutant haplotypes were CVIET (the underline indicates the mutation site). There were 20.0%, 61.4% and 18.6% of P. falciparum parasites carrying the wild-, mutant-, and mixed-type Pfmdr1 gene, respectively, and the mutant haplotypes mainly included YF and NF (the underlines indicate the mutation sites). There were 1.4%, 98.6%, and 0 of P. falciparum parasites carrying the wild-, mutant-, and mixed-type Pfdhfr gene, respectively, and AIRNI was the predominant mutant haplotype (the underline indicates the mutation site). There were 1.4%, 94.3%, and 4.3% of P. falciparum parasites carrying the wild-, mutant-, and mixed-type Pfdhps gene, respectively, and SGKAA was the predominant mutant haplotype (the underline indicates the mutation site). The complete drug-resistant IRNGE genotype consisted of 8.6% of the Pfdhfr and Pfdhps genes, and the K13 gene A578S mutation occurred in 1.4% of the parasite samples. CONCLUSIONS There are mutations in the Pfcrt, Pfmdr1, Pfdhfr, Pfdhps, and K13 genes of P. falciparum imported from Equatorial Guinea to Shandong Province, with a low frequency in the Pfcrt gene mutation and a high frequency in the Pfmdr1, Pfdhfr, and Pfdhps gene mutations, and the K13 gene A578S mutation is detected in the parasite samples.

Abstract
Objectives Since December 2019, the novel coronavirus disease 2019 (COVID-19) that emerged in Wuhan city has spread rapidly around the world. The risk for poor outcome dramatically increases once a patient progresses to the severe or critical stage. The present study aims to investigate the risk factors for disease progression in individuals with mild to moderate COVID-19. Methods We conducted a cohort study that included 1007 individuals with mild to moderate COVID-19 from three hospitals in Wuhan. Clinical characteristics and baseline laboratory findings were collected. Patients were followed up for 28 days for observation of disease progression. The end point was the progression to a more severe disease stage. Results During a follow up of 28 days, 720 patients (71.50%) had recovered or were symptomatically stable, 222 patients (22.05%) had progressed to severe disease, 22 patients (2.18%) had progressed to the critically ill stage and 43 patients (4.27%) had died. Multivariate Cox proportional hazards models identified that increased age (hazard ratio (HR) 2.56, 95% CI 1.97–3.33), male sex (HR 1.79, 95% CI 1.41–2.28), presence of hypertension (HR 1.44, 95% CI 1.11–1.88), diabetes (HR 1.82, 95% CI 1.35–2.44), chronic obstructive pulmonary disease (HR 2.01, 95% CI 1.38–2.93) and coronary artery disease (HR 1.83, 95% CI 1.26–2.66) were risk factors for disease progression. History of smoking was protective against disease progression (HR 0.56, 95% CI 0.34–0.91). Elevated procalcitonin (HR 1.72, 95% CI 1.02–2.90), urea nitrogen (HR 1.72, 95% CI 1.21–2.43), α-hydroxybutyrate dehydrogenase (HR 3.02, 95% CI 1.26–7.21) and D-dimer (HR 2.01, 95% CI 1.12–3.58) at baseline were also associated with risk for disease progression. Conclusions This study identified a panel of risk factors for disease progression in individuals with mild to moderate COVID-19.

Abstract
Objective To predict fetal growth restriction (FGR) by whole‐genome promoter profiling of maternal plasma. Design Nested case–control study. Setting Hospital‐based. Population or Sample 810 pregnancies: 162 FGR cases and 648 controls. Methods We identified gene promoters with a nucleosome footprint that differed between FGR cases and controls based on maternal plasma cell‐free DNA (cfDNA) nucleosome profiling. Optimal classifiers were developed using support vector machine (SVM) and logistic regression (LR) models. Main outcome measures Genes with differential coverages in promoter regions through the low‐coverage whole‐genome sequencing data analysis among FGR cases and controls. Receiver operating characteristic (ROC) analysis (area under the curve [AUC], accuracy, sensitivity and specificity) was used to evaluate the performance of classifiers. Results Through the low‐coverage whole‐genome sequencing data analysis of FGR cases and controls, genes with significantly differential DNA coverage at promoter regions (−1000 to +1000 bp of transcription start sites) were identified. The non‐invasive ‘FGR classifier 1’ (CFGR1) had the highest classification performance (AUC, 0.803; 95% CI 0.767–0.839; accuracy, 83.2%) was developed based on 14 genes with differential promoter coverage using a support vector machine. Conclusions A promising FGR prediction method was successfully developed for assessing the risk of FGR at an early gestational age based on maternal plasma cfDNA nucleosome profiling. Tweetable abstract A promising FGR prediction method was successfully developed, based on maternal plasma cfDNA nucleosome profiling. A promising FGR prediction method was successfully developed, based on maternal plasma cfDNA nucleosome profiling.

Abstract
Background:Malondialdehyde (MDA) is a highly reactive compound produced by lipid-peroxidation in situations associated with oxidative stress. MDA can irreversibly modify proteins residues such as lysine, arginine and histidine. In addition, MDA adducts can further react with acetaldehyde to generate malondialdehyde-acetaldehyde (MAA) modifications. Such modifications can give rise to immunogenic neo-epitopes that are recognized by autoantibodies. In fact, anti-MDA/MAA IgG antibodies are significantly increased in the serum of patients with autoimmune diseases, such as rheumatoid arthritis (RA) (1) and systemic lupus erythematosus (2). Recently, we have shown that anti-MDA/MAA IgG antibodies are able to promote osteoclast (OC) differentiationin vitro(1).Objectives:To investigate the molecular mechanisms triggered by anti-MDA/MAA autoantibodies during osteoclastogenesis.Methods:OCs were generated from monocyte-derived macrophages in the presence of the cytokines RANK-L and M-CSF. The development of OCs was monitored by light microscopy following tartrate-resistant acid phosphatase (TRAP) staining and erosion area on synthetic calcium phosphate-coated plates. Three different recombinant human monoclonal anti-MDA/MAA antibodies, cloned from single synovial B cells of RA patients, control antibodies and Fab fragments of the antibodies were added to OC cultures. Glycolysis was inhibited by 2-deoxyglucose, and Fc-gamma receptor I or II by anti-CD64 or anti-CD16 neutralizing antibodies. IL-8 levels were measured by enzyme linked immunosorbent assay. Cellular metabolism was monitored using Seahorse XF Analyzer (extracellular acidification rate and oxygen consumption) and a colorimetric L-Lactate assay.Results:Lactic acid production correlated with the osteoclastogenetic effect of some but not all anti-MDA/MAA antibodies on OCs (R=0.4758, p=0.0252) suggesting an antibody-mediated regulation of glycolysis. Further, extracellular acidification (ECAR) and oxygen consumption (OCR) rate of the developing OCs were increased by the osteoclastogenic anti-MDA/MAA clones (maximum increase of 54% for the ECAR and 78% for the OCR by clone 146+:01G07, and maximum increase of 28% for the ECAR and 39% for the OCR by clone 1103:01H05), but not by the non-osteoclastogenetic anti-MDA/MAA clones or control antibodies. The glycolysis inhibitor 2-deoxyglucose completely abolished the osteoclastogenetic effect of the anti-MDA/MAA clones at drug concentrations that did not influenced baseline OC development. Fab2 fragments of the osteocalstogenetic anti-MDA/MAA clones had no effect on OC development and metabolism. In accordance with this, Fc-gamma receptor I neutralizing antibodies completely abolished the osteocalstogenetic effect of the anti-MDA/MAA clones. The osteoclastogenetic effect of the anti-MDA/MAA antibodies was independent of IL-8 production. In contrast to anti MDA/MAA antibodies, ACPA-mediated osteoclastogenesis was independent of glycolysis and Fc-gamma receptors but dependent on IL-8.Conclusion:Our results describe a novel glycolysis-dependent mechanism by which anti-MDA/MAA antibodies promote osteoclast development that is different from the one previously described for ACPA.References:[1] C.

Abstract
Background:Both diabetes mellitus (DM) and rheumatoid arthritis (RA) are prevalent diseases and represent the leading causes of disability and mortality worldwide. Systemic chronic inflammation is recognized as the underlying etiology of a variety of diseases, including DM and RA [1]. Additionally, cardiovascular and musculoskeletal complications from DM may influence the outcomes of RA patients.Objectives:To investigate the impact of DM on outcomes of RA patients.Methods:This is a cross-sectional study including 583 RA patients with 5 years’ history after diagnosis in Tan Tock Seng Hospital RA registry, Singapore from 2001 to 2013. Information related to demographics, serologies, clinical features, comorbidities, and outcomes was collected. Independent t-test or Mann-Whitney U test was used to compare continuous quantitative data, while Pearson Chi-square or Fisher Exact test for categorical data. With adjustment for age, gender, ethnicity, smoking and comorbidities, multivariate regressions were performed to analyze the impact of DM on outcomes of RA patients.Results:DM is more prevalent in Malay and Indian patients than Chinese patients with RA (26%, 24% and 11% respectively,p= 0.005). There is no difference of disease activity between DM and non DM patients. There is a tendency that non diabetic RA patients use more methotrexate (p= 0.052) and leflunomide (p= 0.058). Diabetic RA patients are in higher risk of poor American College of Rheumatology (ACR) functional status (p= 0.009), knee arthroplasty (p< 0.001) and admissions (p= 0.006). Adjusted for age, gender, ethnicity, smoking and comorbidities, multivariate regression analyses showed a trend of poor function status for diabetic RA patients, i.e. ACR functional status (adjusted odds ratio [aOR]: 1.802, 95% confidence interval [CI]: 0.968 – 3.353,p= 0.063) and median Health Assessment Questionnaire (HAQ) (β coefficient value: 0.129, 95% CI: -0.010 – 0.267,p= 0.068), and higher risk for knee arthroplasty for diabetic RA patients (aOR: 3.480, 95% CI: 1.016 – 11.920,p= 0.047).Conclusion:This is the first report on the impact of DM on RA outcomes in a long term follow-up RA registry in a multiethnic Asian society.References:[1]Furman, D., Campisi, J., Verdin, E.et al.Chronic inflammation in the etiology of disease across the life span.Nat Med25,1822–1832 (2019).Acknowledgments:TTSH Rheumatoid Arthritis Study GroupDisclosure of Interests:None declared

Abstract
Malignant glioma is a fatal brain tumor whose pathological progression is closely associated with glycolytic reprogramming, leading to the high expression of monocarboxylate transporter 1 (MCT1) and its ancillary protein, cluster of differentiation 147 (CD147) for enhancing lactate efflux. In particular, malignant glioma cells (GMs) release tremendous number of exosomes, nanovesicles of 30 to 200 nm in size, promoting tumor progression by the transport of pro-oncogenic molecules to neighboring cells. In the present study, we found that hypoxia-induced malignant GMs strongly enhanced MCT1 and CD147 expression, playing a crucial role in promoting calcium-dependent exosome release. Furthermore, it was first identified that hypoxic GMs-derived exosomes contained significantly high levels of MCT1 and CD147, which could be quantitatively detected by noninvasive localized surface plasmon resonance and atomic force microscopy biosensors, demonstrating that they could be precise surrogate biomarkers for tracking parent GMs' metabolic reprogramming and malignant progression as liquid biopsies.

Abstract
Dairy cows with high body condition score (BCS) in late prepartum are more susceptible to oxidative stress (OS). Nuclear factor erythroid 2-like 2 (NFE2L2) is a major antioxidant transcription factor. We investigated the effect of precalving BCS on blood biomarkers associated with OS, inflammation, and liver function, along with mRNA and protein abundance of targets related to NFE2L2 and glutathione (GSH) metabolism in s.c. adipose tissue (SAT) of periparturient dairy cows. Twenty-two multiparous Holstein cows were retrospectively classified into a high BCS (HBCS; n = 11, BCS ≥3.5) or normal BCS (NBCS; n = 11, BCS ≤3.17) on d 28 before parturition. Cows were fed a corn silage- and wheat straw-based total mixed ration during late prepartum, and a corn silage- and alfalfa hay-based total mixed ration postpartum. Blood samples obtained at -10, 7, 15, and 30 d relative to parturition were used for analyses of biomarkers associated with inflammation, including albumin, ceruloplasmin, haptoglobin, and myeloperoxidase, as well as OS, including ferric reducing ability of plasma (FRAP), reactive oxygen species (ROS), and β-carotene. Adipose biopsies harvested at -15, 7, and 30 d relative to parturition were analyzed for mRNA (real-time quantitative PCR) and protein abundance (Western blotting) of targets associated with the antioxidant transcription regulator nuclear factor, NFE2L2, and GSH metabolism pathway. In addition, concentrations of GSH, ROS and malondialdehyde were measured. High BCS cows had lower prepartum dry matter intake expressed as a percentage of body weight along with greater BCS loss between -4 and 4 wk relative to parturition. Plasma concentrations of ROS and FRAP increased after parturition regardless of treatment. Compared with NBCS, HBCS cows had greater concentrations of FRAP at d 7 postpartum, which coincided with peak values in those cows. In addition, NBCS cows experienced a marked decrease in plasma ROS after d 7 postpartum, while HBCS cows maintained a constant concentration by d 30 postpartum. Overall, ROS concentrations in SAT were greater in HBCS cows. However, overall mRNA abundance of NFE2L2 was lower and cullin 3 (CUL3), a negative regulator of NFE2L2, was greater in HBCS cows. Although HBCS cows had greater overall total protein abundance of NFE2L2 in SAT, ratio of phosphorylated NFE2L2 to total NFE2L2 was lower, suggesting a decrease in the activity of this antioxidant system. Overall, mRNA abundance of the GSH metabolism-related genes glutathione reductase (GSR), glutathione peroxidase 1 (GPX1), and transaldolase 1 (TALDO1), along with protein abundance of glutathione S-transferase mu 1 (GSTM1), were greater in HBCS cows. Data suggest that HBCS cows might experience greater systemic OS after parturition, while increased abundance of mRNA and protein components of the GSH metabolism pathway in SAT might help alleviate tissue oxidant status. Data underscored the importance of antioxidant mechanisms at the tissue level. Thus, targeting these pathways in SAT during the periparturient period via nutrition might help control tissue remodeling while allowing optimal performance.

Abstract
In the twenty years since the Cultural Revolution, China has maintained fast real growth. This occurred despite China having similar problems to other transitional economies, e.g. loss-making State Owned Enterprises (SOEs), eroding fiscal revenues and inflation, (Section 3).Although China initially adopted the Soviet central planning model, after the 1950s break Chinese planning changed towards a regionally-based system with local planning (Section 2). In contrast to the centrally-based, functionally-specialised (U-form or unitary structure) Soviet model, the Chinese economy is organised on a multi-layer-multi-regional (M-form) basis. This encour aged development of small size township and village enterprises (TVEs), the main engine of Chinese growth.Power and control remained with the Party and the State, but was diffused much more widely, regionally and locally. This allowed initiatives at lower (political) levels to establish institutions, both in agriculture (the ‘household responsibility system’) and industry (TVEs), without state protection. Even among regionally controlled SOEs, ‘tournament rivalry’ between regions, etc., and between SOEs and TVEs provided competition.

Abstract
Objective: To investigate the histopathologic, immunohistochemical, molecular genetic characteristics of dedifferentiated liposarcomas with meningothelial-like whorls(DDLMW). Methods: Six cases of DDLMW diagnosed at Jiangsu Province Hospital(the First Affiliated Hospital of Nanjing Medical University) from March 2012 to August 2018 were enrolled. The cases were analyzed by routine HE staining, immunohistochemistry(MDM2, CDK4 and p16) and fluorescent in-situ hybridization(FISH) on MDM2 gene. Related literatures were also reviewed. Results: Three of the 6 patients were male.The patient ages ranged from 40 to 77 years (mean, 58 years). Four tumors occurred in the retroperitoneum and two in the mediastinum. Histologically, the tumors showed, in addition to foci of well-differentied liposarcoma, characteristic, scattered meningothelial-like concentrical whorls. The whorls were composed of tightly, concentrically arranged, spindle to ovoid cells with mild to mederate cytological atypia. Metaplastic bone was present within or in their immediate vicinity in four case. The tumors cell also showed strong and diffuse immunoreactivity to MDM2, CDK4 and p16, but no immunoreactivity to S-100 protein, SMA, SOX10, EMA, CD21, CD23 or CD35. The Ki-67 labeling indexes were low, while FISH showed high levels of MDM2 amplification in all cases. Conclusions: DDLMW is a rare morphologic variant of dedifferentiated liposarcoma. The whorls in DDLMW do not represent perineurial or follicular dendritic differentiation. Recognition and familiarity with its existence, as well as combined application of immunohistochemical staining and MDM FISH, are important to avoid confusion with other lesions.

Abstract
In this work, poly(vinylpyrrolidone)-stabilized 3-5 nm Rh@Co core-shell nanoparticles were synthesized by a sequential reduction method, which was further in situ transformed into Rh-Co2O3 heteroaggregate nanostructures on alumina supports. The studies of XRD, HAADF-STEM images with phase mappings, XPS, TPR, and DRIFT-IR with CO probes confirm that the as-synthesized Rh@Co nanoparticles were core-shell-like structures with Rh cores and Co-rich shells, and Rh-Co2O3 heteroaggregate nanostructures are obtained by calcination of Rh@Co nanoparticles and subsequent selective H2 reduction. The Rh-Co2O3/Al2O3 nanostructures demonstrated enhanced catalytic performance for hydrogenations of various substituted nitroaromatics relative to individual Rh/Al2O3 and illustrated a high catalytic stability during recycling experiments for o-nitrophenol hydrogenation reactions. The catalytic performance enhancement of Rh-Co2O3/Al2O3 nanocatalysts is ascribed to the Rh-Co2O3 interfaces where the Rh-Co2O3 interaction not only prevents the active Rh particles from agglomeration but also promotes the catalytic hydrogenation performance.

Abstract
The tailorable structure and electronic structure of metal-organic frameworks (MOFs) greatly facilitate their modulated light harvesting, redox power, and consequently photocatalysis. Herein, a representative MOF, UiO-66, was furnished by installing Fe3+ onto the Zr-oxo clusters, to give Fe-UiO-66, which features extended visible light harvesting, based on metal-to-cluster charge transfer (MCCT). The Fe-UiO-66 with unique electronic structure and strong oxidizing power exhibits visible light-driven water oxidation, which is impossible for pristine UiO-66. More strikingly, under visible irradiation, the generated holes over Fe-UiO-66 are able to exclusively convert H2O to hydroxide radicals, initiating and driving the activation of stubborn C-H bond, such as toluene oxidation. The electrons reduce O2 to O2•- radicals that further promote the oxidation reaction. The related catalytic mechanism and the structure-activity relationship have been investigated in detail. As far as we know, this is not only an unprecedented report on activating "inert" MOFs for photocatalytic C-H activation but also the first work on extended light harvesting and enhanced photocatalysis for MOFs by introducing an MCCT process.

Abstract
Backward-angle meson electroproduction above the resonance region, which was previously ignored, is anticipated to offer unique access to the three quark plus sea component of the nucleon wave function. In this Letter, we present the first complete separation of the four electromagnetic structure functions above the resonance region in exclusive ω electroproduction off the proton, ep→e^{'}pω, at central Q^{2} values of 1.60, 2.45 GeV^{2}, at W=2.21 GeV. The results of our pioneering -u≈-u_{min} study demonstrate the existence of a unanticipated backward-angle cross section peak and the feasibility of full L/T/LT/TT separations in this never explored kinematic territory. At Q^{2}=2.45 GeV^{2}, the observed dominance of σ_{T} over σ_{L}, is qualitatively consistent with the collinear QCD description in the near-backward regime, in which the scattering amplitude factorizes into a hard subprocess amplitude and baryon to meson transition distribution amplitudes: universal nonperturbative objects only accessible through backward-angle kinematics.

Abstract
OBJECTIVE To elucidate the function of miRNA-337 in the pathogenesis of diabetic nephropathy (DN) and its underlying mechanism. MATERIALS AND METHODS Type 2 diabetes db/db mice were assigned into db/db group, vehicle group, and si-miR group, and age-matched db/m mice were in the db/m group. Differences in mouse serum glucose, body weight, serum creatinine, and albumin/creatinine ratio (ACR) among the four groups were compared at 6 weeks, 10 weeks, 14 weeks, 18 weeks, and 22 weeks of age. The expression level of miRNA-337 in mouse kidney tissues was determined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Correlation between miRNA-337 expression with ACR was analyzed. Through Western blot analysis, protein levels of interleukin 6 (IL-6), IL-18, podocin, nephrin, and desmin in mouse kidney tissues were detected. RESULTS With the increasing age, serum glucose, body weight, serum creatinine, and ACR in db/db mice gradually increased, which were remarkably higher than age-matched db/m mice. After treatment with miRNA-337 inhibitor in db/db mice, no remarkable changes in serum glucose and body weight were found, while serum creatinine and ACR decreased. Compared with db/m mice, miRNA-337 expression in kidney tissues of db/db mice upregulated, which was positively correlated with ACR. Expression levels of IL-6 and IL-18 in kidney tissues of db/db mice increased relative to db/m mice, but they were downregulated by miRNA-337 inhibitor treatment. Moreover, podocin and nephrin downregulated, while desmin upregulated in kidney tissues of db/db mice than db/m mice. By miRNA-337 inhibitor treatment in db/db mice, levels of podocin and nephrin increased, whereas desmin level decreased. We obtained similar results at their cellular level. CONCLUSIONS We showed that miRNA-337 expression increases in db/db mice with diabetic nephropathy, which leads to podocyte injury by upregulating levels of IL-6 and IL-18.
