Abstract
Objective: To summarize the clinical outcome of abnormal prokaryotic embryos [0PN (non-pronuclear), 1PN (one-pronuclear)] transfer for reference in clinical work. Methods: To collect the clinical data of infertility patients who received in vitro fertilization/intracytoplasmic sperm microinjection-embryo transfer from January 1, 2013 to December 31, 2018 at the reproductive center of Beijing Chaoyang Hospital Affiliated to Capital Medical University, and to retrospectively analyze the pregnancy outcome of the cases of embryo transfer from 0PN and 1PN sources. Results: Forty-seven patients were transplanted non-2PN-derived embryos during 50 cycles. There were 18 cycles which only 0PN embryos were transplanted, and the clinical pregnancy rate was 50.0%. There were 17 cycles which only 1PN embryos were transplanted, and the clinical pregnancy rate was 29.4% (compared with 0PN, the difference was not statistically significant, P>0.05). No abnormalities were found in the delivered newborns. Conclusions: In the absence of 2PN-derived embryos, patients can be transplanted blastocysts from 0PN and 1PN sources. Acceptable clinical pregnancy outcomes can be achieved, and the clinical outcomes of 0PN may be better than 1PN.

Abstract
Despite being the fastest growing sector, the modern aquaculture industry faces serious challenges such as the lack of protein source in feed, the susceptibility to pathogens, and deterioration in quality during culture and storage. Bacterial biomass is considered as a proper protein source for feed, and the beneficial bacterial species protect aquatic animals from infection or reduce spoilage of products. In this review, we summarized the application of beneficial bacteria to aquatic products, focusing mainly on the nutritional, anti-pathogenic, anti-spoilage and immunoregulatory functions of these bacteria. We then discussed the relationship between beneficial bacteria, intestinal microbiota and host immunity, and the recent progress and drawbacks of the technology.

Abstract
The anisotropic extraction dependence of polarized light on propagation path in AlGaN-based deep-ultraviolet (DUV) light-emitting diodes (LEDs) is investigated by simulations and photoluminescence (PL) measurements. Theoretical calculations based on k⋅p approximation and Monte Carol ray tracing indicate that there are two kinds of polarized sources with different angular distributions in ~280 nm AlGaN-based LEDs, s-polarized (spherical-shaped) and p-polarized (dumbbell-shaped) sources, which have different extraction behaviors. It is found that the total light extraction intensities are improved with decreasing the propagation path, and the lateral surface extraction gradually becomes dominant. Moreover, the extraction intensity of s-polarized light improves more than that of p-polarized light when the propagation path decreases, leading to a greater polarization degree. Polarization-resolved PL measurements show that the polarization degree of extracted light from lateral facet of the AlGaN multiple quantum well sample can be enhanced from 1% to 17% as the average propagation path reduces by 0.6 mm, which is consistent with the simulation results of the anisotropic dependence of light extraction on propagation path. Our results are significant for understanding and modulating the anisotropic extraction behavior of polarized light to realize high efficiency AlGaN-based DUV LEDs.

Abstract
The number of H7N9 bird flu cases was high and the situation was grim in guizhou province in 2017. To understand the molecular characteristics of the hemagglutinin gene (HA) and the risk of human infection with avian influenza virus A(H7N9) in Guizhou Province, 2017. Homology, genetic evolution and pivotal sites related to receptor binding regions, pathogenicity and potential glycosylation of 14 avian influenza viruses A(H7N9) were analyzed by a series of bioinformation softwares. It was cleared that there was 95.9%-100% similarity among 14 strains in nucleotide of the HA gene, and there were 96.8%-97.8% and 96.8%-97.9% similarities with vaccine strains A/Shanghai/2/2013 and A/Anhui/1/2013 recommended by WHO, respectively. Phylogenetic analysis showed that 14 HA genes were directly evolved in the Yangtze River Delta evolution branch, but they could be derived from five diffenrent strains. Then 13 of 14 strains cleavage site sequences of HA protein revealed they were low pathogenic avian influenza viruses, while A/Guizhou-Weining/CSY01/2017 was high pathogenic avian influenza virus. Mutation G186V at the receptor binding sites in the HA was found in all 14 strains, and mutation Q226L in 13 strains besides A/Guizhou-Weining/CSY01/2017. All five potential glycosylation motifs in the HA were conservative.

Abstract
A growing number of evidences accumulated about critical metabolic role of cannabinoid type 1 receptor (CB1), carnitine palmitoyltransferase-1 (CPT1) and peroxisome proliferator-activated receptors (PPARs) in some peripheral tissues, including adipose tissue, liver, skeletal muscle and heart. To better understand the interactions of CB1, CPT1 and PPARs in these tissues, 30 diet-induced obese (DIO) C57BL/6J male mice were obtained, weight-matched and divided into two groups (15 in each group): (i) DIO/vehicle mice (D-Veh) and (ii) DIO/SR141716 mice (D-SR) treated with SR141716 (or rimonabant, a selective CB1 receptor blocker) administered orally (10 mg/kg daily). Another 15 mice fed standard diet (STD) formed the STD/vehicle group (S-Veh). At the end of 3-week treatment, mean body weight was 28.4 ± 0.5, 36.5 ± 0.8, and 30.3 ± 1.2 g for the S-Veh, D-Veh, and D-SR group, respectively (p < 0.05; D-Veh vs. D-SR). Liver weight in the D-SR group was also decreased significantly compared to the D-Veh group (p < 0.05). Serum levels of total cholesterol, high-density lipoprotein cholesterol, leptin and adiponectin in the D-SR group were ameliorated compared to the D-Veh group (p < 0.05). Both qRT-PCR and Western blot assay revealed that CB1 expression levels were efficiently blocked by SR141716 in subcutaneous adipose tissue (SAT), visceral adipose tissue (VAT), skeletal muscles and liver (D-SR vs. D-Veh; p < 0.05), whereas there was no significant difference between S-Veh and D-Veh mice (p > 0.05). Simultaneously with the reduction of CB1 expression in the D-SR group, the expression levels of CPT1A isoform (protein) in the liver and heart and CPT1B isoform (protein) in the SAT, VAT, liver and skeletal muscles were significantly increased (p < 0.05; D-SR vs. D-Veh). Interestingly, the CPT1A and CPT1B expression levels in heart were detected slightly. The expression levels of PPARα in the SAT, VAT, liver and skeletal muscles and PPARγ in the SAT and skeletal muscles in the D-SR group were significantly increased compared to the D-Veh mice (p < 0.05). However, the PPARβ expression level differed from that of PPARα and PPARγ. Taken together, these data indicate that the inhibition of CB1 could ameliorate lipid metabolism via the stimulation of the CPT1A and CPT1B expression in vivo. Simultaneously, the PPARα and PPARγ expression levels significantly differed compared to that of PPARβ in obesity and lipid metabolism-related disorders under blockade of CB1. Both the mechanism of the influence of CB1 inhibition on lipid metabolism in the examined tissues and the specific mechanism of PPARα, PPARγ and PPARβ involvement in lipid exchange under these conditions remain to be further elucidated.

Abstract
To investigate the expression of microRNA-34a (miR-34a) in patients with chronic lymphocytic leukemia (CLL) in Xinjiang Uygur and Han nationalities and its prognostic significance. Our data showed that miR-34a expression in Uygur and Han CLL patients was significantly higher than that in their respective healthy controls, while miR-34a levels were similar between Uygur and Han patients. By comparing with known prognostic factors, receiver operating characteristic (ROC) curves showed that miR-34a was a good predictive factor for the prognosis of CLL (demarcation value was 3.567 6). Survival analysis was further performed according to miR-34a expression level, that low expression of miR-34a translated into poor prognosis.

Abstract
AIMS To describe patterns of primary and diabetes care during transition age (17 to < 19 years) into early adulthood (age 19 to 26 years), and to evaluate the association of primary and diabetes care patterns during transition age with the risk of adverse events in early adulthood. METHODS We conducted a population-based cohort study of individuals in Ontario, Canada who were diagnosed with diabetes aged < 15 years and who turned 17 between November 2006 and March 2011, followed until March 2015 (n = 2525). Using linked administrative databases, we examined healthcare use during: 'pre-transition-age' (15 to < 17 years), 'transition-age' (17 to < 19 years), and 'early adulthood' (19 to 26 years). The main outcomes were time to death or ketoacidosis and rate of diabetes-related admissions. The main exposures were the gap in diabetes care and primary care visits during transition age. RESULTS There were < 6 deaths and 446 individuals (17.7%) had at least one admission for ketoacidosis during early adulthood. In all, 1188 individuals (47.0%) had a > 12-month gap in diabetes care and 241 (9.5%) had no primary care visits during transition age. A gap in diabetes care of > 12 months and no primary care visits during transition age were associated with an increased risk of ketoacidosis or death (adjusted hazard ratio 1.31, 95% CI 1.04-1.66 and adjusted hazard ratio 1.42, 95% CI 1.02-1.97, respectively). CONCLUSIONS In Ontario, Canada, where physician and hospital-based services are universally covered, a high proportion of young adults with diabetes have insufficient care during transition age and this is associated with a higher risk of important adverse outcomes in early adulthood. Ensuring primary care involvement during transition may be a strategy to reduce morbidity.

Abstract
Michel Boym was a 17th-century missionary who came to China from Poland. He was the first man who introduce Chinese herbal medicine to Europe by writing Flora Sinensis (Chinese Flora) and Medicamenta Simplicia quae Chinensibus ad usum medicum adhibentur. This article reveals that which Chinese herbal medicine books may have been consulted in the Medicamenta Simplicia quae Chinensibus ad usum medicum adhibentur by analyzing its content and comparing it with the Chinese herbal medicine books. We believed that in order to write this book, he consulted many Chinese books, collected a variety of herbal samples and consulted Chinese people who knew about herbals, and added his own understanding. As a western pharmacology book, his book structure, content and characteristics are the closest to Chinese herbal medicine books. And which Chinese books he has consulted, may include, but is not limited to BenCao GangMu(Compendium of Materia Medica)《》, Lei Gong Pao Zhi Yao Xing Jie 《》, Ben Cao Meng Quan《》 and Xin Kan Lei Gong Pao Zhi Bian Lan 《》.

Abstract
The shortage of deceased-donor organs is compounded by donation metrics that fail to account for the total pool of possible donors, leading to ambiguous donor statistics. We sought to assess potential metrics of organ procurement organizations (OPOs) utilizing data from the Nationwide Inpatient Sample (NIS) from 2009-2012 and State Inpatient Databases (SIDs) from 2008-2014. A possible donor was defined as a ventilated inpatient death ≤75 years of age, without multi-organ system failure, sepsis, or cancer, whose cause of death was consistent with organ donation. These estimates were compared to patient-level data from chart review from two large OPOs. Among 2,907,658 inpatient deaths from 2009-2012, 96,028 (3.3%) were a "possible deceased-organ donor." The two proposed metrics of OPO performance were: (1) donation percentage (percentage of possible deceased-donors who become actual donors; range: 20.0-57.0%); and (2) organs transplanted per possible donor (range: 0.52-1.74). These metrics allow for comparisons of OPO performance and geographic-level donation rates, and identify areas in greatest need of interventions to improve donation rates. We demonstrate that administrative data can be used to identify possible deceased donors in the US and could be a data source for CMS to implement new OPO performance metrics in a standardized fashion.

Abstract
Objective: To investigate the influence of high-fat diet (HFD) in paternal C57BL/6 mice on HFD-induced liver fat deposition in male offspring, as well as transgenerational inheritance caused by paternal HFD and related mechanisms. Methods: A total of 20 male C57BL/6 mice aged 3 weeks (F0) were randomly divided into normal control group (C, 10 mice) and HFD group (HF, 10 mice). After 12 weeks of HFD intervention, the male mice in the HFD group mated with female ones treated with normal diet and pups were obtained. Male pups (F1) were selected as study subjects. According to the intervention for F0 mice, male F1 mice were divided into control male offspring group (CM, 8 mice) and HFD male offspring group (HFM, 9 mice). All these mice were given normal diet after weaning until 4 weeks old, followed by HFD for 4 weeks. The body length and body weight were measured and recorded every week. Oil red O staining was used to observe fat deposition in the liver. Western blot and real-time PCR were used to measure the expression of related proteins and genes involved in the de novo synthesis and aerobic oxidation of fatty acid, mitochondriogenesis, and autophagy. Results: After 4 weeks of HFD intervention, the HFM group had a significantly higher body weight than the CM group (P < 0.05); the oil red O staining showed that compared with the CM group, the HFM had a significant increase in liver fat deposition and a significantly higher integral absorbance value in the oil red O staining-positive area (384 360±57 600 vs 236 754±12 607, P < 0.01). For related factors involved in the de novo synthesis of fatty acid in the liver, compared with the CM group, the HFM group had significant increases in the expression of sterol regulatory element-binding protein-1 and fatty acid synthase (P < 0.05); for related factors involved in the mitochondrial biosynthesis in the liver, the HFM group had significant reductions in the relative expression of peroxisome proliferator-activated receptor-γ coactivator-1α, nuclear respiratory factor 1, and mitochondrial transcription factor A compared with the CM group (P < 0.05). For autophagy-related factors in the liver in the F1 mice, compared with the CM group, the HFM group had a significant reduction in microtubule-associated protein I light chain 3 (LC3-II/I) (P < 0.05) and a significant increase in P62 (P < 0.05), suggesting a reduced autophagy function in the liver. Conclusion: HFD intervention for paternal C57BL/6 mice can increase HFD-induced liver fat deposition in male offspring, which may be related to the increased de novo synthesis of fatty acid and reduced mitochondriogenesis and autophagy function in the liver.

Results: Conditioning regimens consisted of total body irradiation/etoposide/cyclophosphamide (TBI/VP-16/CTX) and busulfan (Bu)/VP-16/CTX in HLH with anti-thymocyte globulin (ATG) 8 mg/kg.The stem cells were mobilized from donors' peripheral blood.Median time to white blood cell engraftment was 13 (9-27) days.Median time to platelet engraftment was 14 (10-28) days.Mixed chimerism after transplantation developed in 4 patients and no patient presented graft failure.Eight patients developed grade Ⅱ to Ⅲ acute graft-versus-host disease (GVHD), while as chronic GVHD occurred in 9 patients.Among 12 patients with EB virus(EBV) reactivation, 2 patients developed post-transplant lymphoproliferative disorder (PTLD), 7 were suspected as PTLD and 3 were considered as relapse of primary disease.With a median follow-up of 20 months (range: 0.5-108 months) after transplantation, the estimated 2-year overall survival (OS) rate was (60.0±11.0)% in all patients.During the follow-up, 12 patients survived, 8 died including 5 within 100 days after HSCT.Among 5 non-remission patients before HSCT, 4 patients died within 100 days after HCT. Conclusions: HID HSCT is an effective treatment for adult patients with HLH to achieve remission and long-term survival. High proportion of mixed chimerism has been seen at early stage after transplantation.EBV reactivation and early transplant-related mortality are common.

Abstract
Objective: To evaluate the efficacy and safety of maintenance therapy with reduced dose of rhTPO in the patients with primary immune thrombocytopenia (ITP) who attained stable platelet (PLT) counts after daily administration of rhTPO. Methods: Treatment was started with a daily administration of rhTPO (300 U/kg) for 2 consecutive weeks. Patients who attained stable PLT≥50×10(9)/L were enrolled to maintenance therapy starting with every other day administration of rhTPO, then adjusted dose interval to maintain platelet count (30-100) ×10(9)/L. Results: A total of 91 eligible patients were enrolled. Fourteen patients discontinued the study due to noncompliance (12/14) and investigator decision (2/14) . Among 77 patients who completed the study, 38 patients with the administration of rhTPO at every other day or less could maintain PLT≥30×10(9)/L for 12 weeks. The percentage of patients with a platelet response (PLT≥30×10(9)/L) at 4(th) week, 8(th) week and 12(th) week of maintain therapy was 92.6% (63/68) , 82.7% (43/52) and 85.0% (34/40) , respectively. Median platelet counts remained in the range of (70-124) ×10(9)/L. The overall incidence of rhTPO-related adverse events was 7.7%. All the adverse events were generally mild. Conclusion: Extending the dose interval of rhTPO is feasible to maintain stable platelet count in the patients with ITP, but the optimal dose interval is uncertain and might vary with individuals.

Abstract
Objective: To evaluate the value of dynamic contrast-enhanced MR (DCE-MRI) and diffusion weighted MR (DWI) in differential diagnosis of inflammatory pseudotumor and lymphoma in the lacrimal gland. Methods: In this retrospective study, a total of 24 cases of inflammatory pseudotumor and 22 cases of lymphoma in the lacrimal gland at Beijing Tongren Hospital confirmed by histological results were enrolled from January 2010 to January 2015.DCE-MRI and DWI were performed in these cases, and the type of time-signal intensity curve (time-intensity curve, TIC), the peak contrast index (CIpeak), maximum enhancement ratio (ERmax), washout ratio (WR) and ADC value were analyzed.Differences of these parameters between inflammatory pseudotumor and lymphoma in the lacrimal gland was evaluated by independent samples t test or Mann-Whitney U test.The receiver operating characteristic analysis was used to evaluate the utility of these parameters in discriminating the two diseases. Results: Type of TIC, CIpeak, WR, ERmax and ADC values were statistically different (all P<0.05) between the inflammatory pseudotumor and lymphoma in the lacrimal gland.ERmax, CIpeak and ADC values of inflammatory pseudotumor were greater than those of lymphoma, but the WR values of inflammatory pseudotumor was less than those of lymphoma.The area under the ROC of the CIpeak, WR, ERmax and ADC values was 0.68±0.08, 0.70±0.08, 0.70±0.08, 0.84±0.81 respectively.Using an ADC(b=0, 1000) value of 1.005×10(-3) mm(2)/s as the diagnostic threshold, the sensitivity, specificity and accuracy to differentiate benign lesions from malignant lesions were 84.2%, 65.0% and 75.0% respectively.The diagnostic ability of DWI combined with DCE-MRI was superior to that of DCE-MRI(P=0.000) or DWI alone(P=0.008) with overall sensitivity, specificity and accuracy of 86.3%, 87.5% and 86.9%. Conclusion: DCE-MRI and DWI may improve the diagnostic accuracy in differentiation of the inflammatory pseudotumors and lymphomas in the lacrimal gland, and play an important role in differentiation among them.

Abstract
OBJECTIVE The AML1-ETO fusion protein (AE) resulting from the t(8;21) translocation is highly related to the pathogenesis and development of leukemia. microRNA-9 (miR-9) acts as a tumor suppressor gene in AE-positive acute myeloid leukemia (AML). Silent mating type information regulation 2 homolog-1 (SIRT1) is overexpressed in most cancer cells by increasing proliferation as a tumorigenic gene. The present study was performed to investigate the underlying interaction between miR-9 and SIRT1 in AE-positive AML. PATIENTS AND METHODS Expression of miR-9 and SIRT1 in AE-positive AML patients, healthy donors and AML cell lines were detected by qPCR. Relevance between miR-9 and SIRT1 was assessed by plasmid transfection, Western blot and correlation analysis. Luciferase assay was used to confirm the target gene of miR-9. Knockdown of SIRT1 in different cell lines was achieved by shRNA transfection and CCK-8 assay was used to investigate the effects on cell proliferation. RESULTS The miR-9 expression was lower in AE-positive cell lines compared to that in other AE-negative AML cell lines, while expression of SIRT1 was higher in AE-positive cell lines. Expression of miR-9 was also downregulated in adult primary t(8;21) AML patients compared to healthy donors. The over-expression of miR-9 decreased luciferase activity of wild-type SIRT1, which was recovered after transfection with mutant SIRT1. The miR-9 directly targets SIRT1 by binding to its 3'-untranslated region and reducing its protein levels. Importantly, miR-9 and SIRT1 mRNA levels were inversely correlated in AE-positive AML cell lines and t(8;21) AML primary leukemia cells. Knockdown of SIRT1 levels using shSIRT1 inhibited cell proliferation in AE-positive AML cell lines. CONCLUSIONS SIRT1 is the target gene of miR-9 and the signaling pathway connecting miR-9 and SIRT1 is a therapeutic target for t(8;21) AML.

Abstract
We discover a pair of spin-polarized surface bands on the (111) face of grey arsenic by using angle-resolved photoemission spectroscopy (ARPES). In the occupied side, the pair resembles typical nearly-free-electron Shockley states observed on noble-metal surfaces. However, pump-probe ARPES reveals that the spin-polarized pair traverses the bulk band gap and that the crossing of the pair at Γ[over ¯] is topologically unavoidable. First-principles calculations well reproduce the bands and their nontrivial topology; the calculations also support that the surface states are of Shockley type because they arise from a band inversion caused by crystal field. The results provide compelling evidence that topological Shockley states are realized on As(111).

Abstract
In this study, we retrieved a series of 59 dihydroalkylthio-benzyloxopyrimidine (S-DABO) derivatives, which is a class of highly potent HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs) reported from published articles, and analysed them with comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA). Statistically significant three-dimensional quantitative structure-activity relationship (3D-QSAR) models by CoMFA and CoMSIA were derived from a training set of 46 compounds on the basis of the rigid body alignment. Further, the predictive ability of the QSAR models was validated by a test set of 13 compounds. Based on the information derived from CoMFA and CoMSIA contour maps, we have identified some steric and electrostatic features for improving the activities of these inhibitors, and we validated the 3D-QSAR results by a molecular docking method. On the basis of the obtained results, we designed a new series of S-DABO derivatives with high activities. Therefore, this study could be utilized to design more potent S-DABO analogues as anti-HIV agents.

Abstract
It is still controversial whether maternal anti-HBV antibodies (anti-HBVs) affect the infants' immune response to hepatitis B virus (HBV) vaccination. This multicentre study aims to address this question. First, we determined whether the transplacental transfer of maternal anti-HBVs occurs by measuring the titres of 90 anti-HBVs-positive pregnant women and their newborns. The anti-HBVs-positive rates of newborns ranged from 89.7% to 100.0%, depending on the maternal anti-HBVs titres. Secondly, we investigated the effects of maternal anti-HBVs on the immune response of infants to HBV vaccination. A total of 1063 mother-and-infant pairs were enrolled and divided into three groups with maternal anti-HBVs titres of <10 IU/L (negative - 37.9%), 10-499 and ≥500 IU/L. The infants' anti-HBVs-positive rate and titres were negatively correlated with maternal anti-HBVs titres: the anti-HBVs-positive rate of infants were 88.9% (360/405), 84.5% (381/451) and 77.3% (160/207) in mothers with low, intermediate and high antibody titres, respectively, P<.0001. Median titres of anti-HBVs (IU/L) among infants were 169.1, 141.0 and 79.4, respectively, P=.020. One hundred and sixty-two infants were negative for anti-HBVs after the standard vaccination, and 120 of 131 of these infants (91.6%) reached anti-HBVs positivity after the first "booster" dose. The maternal anti-HBVs titres did not significantly affect infant response to this booster. In summary, transplacental transfer of anti-HBVs occurs and high titres of maternal anti-HBVs may suppress the immune response of infants to the standard HBV vaccination. The current schedule of the 0, 1 and 6 month may not be the optimal choice of infants with anti-HBVs-positive mothers.

Abstract
The effects of 1-methylcyclopropene (1-MCP) on the fruit quality and physiological disorders in Yali pear ( Pyrus bretschneideri Rehd.) after harvest were researched. The fruit was exposed to 0, 0.01, 0.1, 0.2 or 0.5 μL/L 1-MCP for 24h, or exposed to 0.2 μL/L 1-MCP for 0, 12, 24 or 48h. Thereafter, the fruit was stored at 20°C and 85–95% RH. Pears treated with 1-MCP maintained higher firmness and soluble solids content than those of the control fruit. The incidence and index of core browning (CB) in Yali pears was reduced by 91% and 97% by 1-MCP treatment 100 days after storage, respectively. The occurrence of black and withered stems in Yali pears was also reduced by 59% by 1-MCP 32 days after storage. The 1-MCP treatment had an inhibitory effect on ethylene production and respiration rate in the pears. The activities of antioxidant enzymes (catalase, superoxide dismutase and peroxidase) were all significantly higher in 1-MCP-treated pears than in the control fruit. The beneficial effect of 1-MCP on improving postharvest quality and reducing physiological disorders in Yali pears might be due to its ability to increase the antioxidant potential as well as to delay fruit ripening and senescence. The 1-MCP is recommended to control Yali pear disorders during storage.

Abstract
The complementary DNA (cDNA) of the giant panda (Ailuropoda melanoleuca) ferritin light polypeptide (FTL) gene was successfully cloned using reverse transcription-polymerase chain reaction technology. We constructed a recombinant expression vector containing FTL cDNA and overexpressed it in Escherichia coli using pET28a plasmids. The expressed protein was then purified by nickel chelate affinity chromatography. The cloned cDNA fragment was 580 bp long and contained an open reading frame of 525 bp. The deduced protein sequence was composed of 175 amino acids and had an estimated molecular weight of 19.90 kDa, with an isoelectric point of 5.53. Topology prediction revealed one N-glycosylation site, two casein kinase II phosphorylation sites, one N-myristoylation site, two protein kinase C phosphorylation sites, and one cell attachment sequence. Alignment indicated that the nucleotide and deduced amino acid sequences are highly conserved across several mammals, including Homo sapiens, Cavia porcellus, Equus caballus, and Felis catus, among others. The FTL gene was readily expressed in E. coli, which gave rise to the accumulation of a polypeptide of the expected size (25.50 kDa, including an N-terminal polyhistidine tag).

Abstract
Janus-activated kinase (JAKs)-signal transducer and activator of transcription 3 (STAT-3) signalling play critical roles in immunoregulation and immunopathology, which involve inflammatory responses and enteritis. JAK phosphorylates STAT-3 in response to stimulation by cytokines or growth factors, and then activates or represses the gene expression. STAT-3 is activated persistently in cancer cells and contributes to the malignant progression of various types of cancer and inflammation. To elucidate the different roles of JAKs in the activation of STAT-3, the lipopolysaccharide-induced primary intestinal epithelial cell (IEC) acute inflammatory model was established. Small interference RNAs (siRNAs) were then employed to attenuate the expression levels of JAKs. Real-time quantitative reverse transcription-polymerase chain reaction (PCR) (qRT-PCR) revealed that JAK mRNA levels were reduced efficiently by JAK-specific siRNAs. Under the IEC inflammatory model transfected with si-JAK, which equates to effective silencing, qRT-PCR and Western blot assays, suggested that knockdowns of JAK attenuated the JAK-induced down-regulation of STAT-3 at the mRNA or protein levels. In particular, JAK1 played a key role, which was consistent with the RNA-Seq results. Subsequently, the expression levels of proinflammatory cytokines interleukin (IL)-1β and tumour necrosis factor (TNF)-α were down-regulated in the IEC inflammatory model transfected with si-JAK1. JAK1 appears as a direct activator for STAT-3, whereas treatments targeting JAK1 repressed STAT-3 sufficiently pathways in the IEC inflammatory model. Therefore, the control of JAK1 using siRNAs has the potential to be an effective strategy against enteritis.

Abstract
Apolipoprotein A-II (apoA-II), an apolipoprotein in serum high-density lipoprotein, is a precursor of mouse senile amyloid fibrils. The liver has been considered to be the primary site of synthesis. However, we performed nonradioactive in situ hybridization analysis in tissue sections from young and old amyloidogenic (R1.P1- Apoa2 c ) and amyloid-resistant (SAMR1) mice and revealed that other tissues in addition to the liver synthesize apoA-II. We found a strong hybridization signal in the basal cells of the squamous epithelium and the chief cells of the fundic gland in the stomach, the crypt cells and a small portion of the absorptive epithelial cells in the small intestine, the basal cells of the tongue mucosa, and the basal cells of the epidermis and hair follicles in the skin in both mouse strains. Expression of apoA-II mRNA in those tissues was also examined by RT-PCR analysis. Immunolocalization of apoA-II protein also indicated the cellular localization of apoA-II. ApoA-II transcription was not observed in the heart. Amyloid deposition was observed around the cells expressing apoA-II mRNA in the old R1.P1- Apoa2 c mice. These results demonstrate that the apoA-II mRNA is transcribed and translated in various extrahepatic tissues and suggest a possible contribution of apoA-II synthesized in these tissues to amyloid deposition.

Abstract
BACKGROUND Damage to melanocytes induced by oxidative stress plays an important role in the pathogenesis of vitiligo. A polyphenol found in green tea, (-)-epigallocatechin-3-gallate (EGCG), exhibits certain antioxidative effects in the treatment of various diseases. The major problem that limits the clinical application of this polyphenol is its low bioavailability and stability. Peracetylated EGCG (AcEGCG), a fully acetylated derivative of EGCG, is more stable and bioavailable than EGCG, but the effects of its action on human epidermal melanocytes have not been elucidated. AIM To compare the protective effects of AcEGCG and EGCG on hydrogen peroxide (H2 O2 )-induced damage to human melanocytes. METHODS Effects of AcEGCG and EGCG on human melanocytes were examined by measuring cell viability, levels of reactive oxygen species (ROS), the mitochondrial membrane potential (ΔΨm)and protein levels of caspase-9, caspase-3 and p38 mitogen-activated protein kinase. RESULTS Both AcEGCG and EGCG decreased ROS generation, restored lost mitochondrial membrane potential and reduced H2 O2 -induced apoptosis in melanocytes. All of these effects were more pronounced with AcEGCG than with EGCG. Furthermore, AcEGCG effectively suppressed H2 O2 -induced p38 mitogen-activated protein kinase phosphorylation, which has been suggested to contribute to melanocyte damage. CONCLUSIONS AcEGCG is a more potent agent than EGCG for protection of melanocytes from oxidative damage.

Abstract
Thyroid cancer (TC) is one of the most common endocrine malignancies, with a steadily increasing incidence and lethality over the last several decades. ERα is a nuclear hormone receptor that has a key role in different cellular process and participates in the development and progression of thyroid cancer. ERα is the predicted target gene of microRNA-1280 (miR-1280). The present study was designed to delineate the role and underlying mechanism of miR-1280 in regulating thyroid cancer through targeting ERα. In our study, we analyzed the expression level of miR-1280 in thyroid cancer and detected significantly lower miR-1280 levels in TC tissue and cell lines compared with adjacent normal tissue or healthy cell line. We then overexpressed miR-1280 by miRNA mimic transfection and inhibited miR-1280 by miRNA inhibitor transfection. The inhibition of miR-1280 significantly elevated proliferation and invasion ability, whereas overexpression of miR-1280 inhibited cell growth and invasion in TC cells. Additionally, the luciferase reporter assay confirmed a targeting reaction between miR-1280 and ERα. Furthermore, overexpression of miR-1280 inhibited ERα and ERK pathway expression in TC cells, indicating that miR-1280 acts as a tumor suppressor by inhibiting the expression of ERα. Taken together, we demonstrated that overexpressed miR-1280 levels in TC cells may promote cell proliferation and invasion by inhibiting ERα, which might provide a new therapeutic target for thyroid cancer.

Abstract
We have developed an original experimental setup, coupling tribology, and velocimetry experiments together with a direct visualization of the contact. The significant interest of the setup is to measure simultaneously the apparent friction coefficient and the velocity of confined layers down to molecular scale. The major challenge of this experimental coupling is to catch information on a nanometer-thick sheared zone confined between a rigid spherical indenter of millimetric radius sliding on a flat surface at constant speed. In order to demonstrate the accuracy of this setup to investigate nanometer-scale sliding layers, we studied a model lipid monolayer deposited on glass slides. It shows that our experimental setup will, therefore, help to highlight the hydrodynamic of such sheared confined layers in lubrication, biolubrication, or friction on solid polymer.

Abstract
BACKGROUND Few studies have explored the risk factors of sarcopenia in certain cohorts. The objective of this study was to examine the incidence of sarcopenia and associated factors over a 1-year period in an elderly Chinese suburban population. METHODS This study was conducted on 356 Chinese suburb-dwelling participants aged ≥60 years, for whom detailed information regarding sociodemographics, behavioral characteristics, and medical conditions had been documented. Sarcopenia was defined according to the Asian Working Group for Sarcopenia (AWGS) criteria. Sarcopenia incidence was documented after one year of follow-up, and correlated with several possible factors. RESULTS At baseline, 64 (9.7%) of the initial 657 participants had sarcopenia. The prevalence of sarcopenia was 10.4% after one year. Between baseline and 1-year follow-up, 13 of the participants without sarcopenia at baseline had developed sarcopenia. After multivariate adjustments, it was found that the incidence of sarcopenia increased with age and high body mass index (BMI) is associated with less incidence of sarcopenia. Incidence was also higher among women. CONCLUSIONS We found sarcopenia incidence increased with age, and women were more likely to have sarcopenia. A higher BMI is also associated with a lower incidence of sarcopenia. Maintaining a healthy weight could be beneficial in the prevention of sarcopenia.

Abstract
To date, research on laccases has mostly been focused on plant and fungal laccases and their current use in biotechnological applications. In contrast, little is known about laccases from plant pathogens, although recent rapid progress in whole genome sequencing of an increasing number of organisms has facilitated their identification and ascertainment of their origins. In this study, a comparative analysis was performed to elucidate the distribution of laccases among bacteria, fungi, and oomycetes, and, through comparison of their amino acids, to determine the relationships between them. We retrieved the laccase genes for the 20 publicly available plant pathogen genomes. From these, 125 laccase genes were identified in total, including seven in bacterial genomes, 101 in fungal genomes, and 17 in oomycete genomes. Most of the predicted protein models of these genes shared typical fungal laccase characteristics, possessing four conserved domains with one cysteine and ten histidine residues at these domains. Phylogenetic analysis illustrated that laccases from bacteria and oomycetes were grouped into two distinct clades, whereas fungal laccases clustered in three main clades. These results provide the theoretical groundwork regarding the role of laccases in plant pathogens and might be used to guide future research into these enzymes.

Abstract
PURPOSE Trend-based analyses examining rates of visual field (VF) loss in glaucoma are useful for predicting risk of vision-related morbidity. Although patients with faster losses are likely to require treatment escalation, little is known about rates that might trigger a decision to intervene surgically. The aims of this study were to investigate prior rates of VF loss in patients attending for trabeculectomy and to estimate, in the absence of surgical intervention, lifetime risk of visual impairment, and blindness. PATIENTS AND METHODS A retrospective analysis of 117 eyes of 86 consecutive patients with glaucoma attending for trabeculectomy, including 53 patients referred from general ophthalmology clinics and 33 patients from specialist glaucoma clinics. Rates of change in standard automated perimetry mean deviation were examined using linear regression and random coefficient models. Risk of lifetime visual impairment and blindness was calculated using life expectancy data. RESULTS Mean age at surgery was 71.0±9.7 years. Patients were followed for 10.7±7.5 years prior to surgery with an average of seven useable fields per eye. On average patients referred from general clinics lost 1.04 dB/year compared with 0.77 dB/year in those referred from glaucoma clinics (P=0.070). Patients referred from general clinics had more medication changes prior to surgery (3.4 and 2.6 changes, respectively; P=0.004). Given Scottish life expectancy data, untreated, 61 eyes (52%) would have passed the threshold for visual impairment, whereas 40 (34%) would have passed the threshold demarcating blindness. CONCLUSION Patients attending for trabeculectomy had faster average rates of field loss prior to surgery than published values for the general glaucoma population with over one-third of eyes studied predicted to have become blind without intervention. Those managed by glaucoma specialists had fewer changes in medication and tended to slower rates of VF loss, although the latter did not reach statistical significance.

Abstract
Organophosphorus exposure affects different organs such as the lung, gastrointestinal tract, liver, and brain. The present experiment aimed to evaluate the effect of ginsenoside Rg3 on lung injury induced by acute omethoate poisoning. Rats were administered with omethoate subcutaneously at a single dose of 60 mg/kg, followed by ginsenoside Rg3 (5, 10, or 20 mg/kg) treatment. Histopathological examination of the lung was performed at 24 h after the omethoate exposure. The antioxidative parameters in the lung were also assayed. Moreover, the activities of acetylcholinesterase, myeloperoxidase, and the content of tumor necrosis factor α (TNF-α) in the lung were determined. The results showed that ginsenoside Rg3 attenuated omethoate-induced lung injury. Ginsenoside Rg3 increased the level of glutathione in the lung ( p < 0.05 or p < 0.01). The altered activities of superoxide dismutase and catalase in the lung were also ameliorated by ginsenoside Rg3 treatment ( p < 0.05 or p < 0.01). Ginsenoside Rg3 caused significant reductions in the contents of malondialdehyde, TNF-α, and the activity of myeloperoxidase ( p < 0.05 or p < 0.01). The present study demonstrated that ginsenoside Rg3 had a protective effect against omethoate-induced lung injury in rats, and the mechanisms were related to its antioxidant potential and anti-inflammatory effect.
