oryzae. In particular, MoCUE1 was important for ER stress response and localization and translocation of cytoplasmic effectors. Moreover, ubiquitination and SUMOylation levels were decreased and transcript levels of deSUMOylation-associated genes were increased in ΔMofbx15 and ΔMocue1. This study will provide not only comprehensive understanding of the role of ubiquitination but also new insights on crosstalk between ubiquitination and SUMOylation in rice blast fungus and other fungal pathogens.
There are two different approaches to involve participants in consecutive rounds of a Delphi survey (1) invitation to every round independent of response to the previous round ("all-rounds") and (2) invitation only when responded to the previous round ("respondents-only"). This study aimed to investigate the effect of invitation approach on the response rate and final outcome of a Delphi survey.

Both experts (N=188) and patients (N=188) took part in a Delphi survey to update the core outcome set (COS) for axial spondyloarthritis. A study with 11 allocation to two experimental groups (ie, "all-rounds" [N=187] and "respondents-only" [N=189]) was built-in.

The overall response rate was lower in the "respondents-only group" (46%) compared to the "all-rounds group" (61%). All domains that were selected for inclusion in the COS by the "respondents-only group" were also selected by the "all-rounds group." Additionally, the four most important domains were identical between groups after the final round, with only minor differences in the other domains.

Inviting panel members who missed a round to a subsequent round will lead to a better representation of opinions of the originally invited panel and reduces the chance of false consensus, while it does not influence the final outcome of the Delphi.

New diagnostic tests to identify a well-established disease state must undergo a series of scientific studies from test construction to finally demonstrating a societal impact. Traditionally, these studies are performed with substantial time gaps in between, resulting in a long time period from the initial idea to roll out in clinical practice including reimbursement. Seamless designs allowing us to combine a sequence of studies in one protocol may hence accelerate this process. Currently, a systematic investigation of the potential of seamless designs in diagnostic research is lacking.

We identify major study types in diagnostic research and their basic characteristics with respect to the application of seamless designs. This information is used to identify major hurdles and opportunities for seamless designs.

The following major study types were identified Variable construction studies, cut point finding studies, variable value studies, single-arm accuracy studies, comparative accuracy studies, changeconstruction to the comparison with the comparator can be combined in one protocol. This may include a switch from case-control to population-based recruitment as well as a switch from a single-arm study to a comparative accuracy study. In addition, change-in-management studies can be combined with an outcome study in discordant pairs.

There is a potential for seamless designs in diagnostic research. It is wise to have the whole sequence of necessary studies in mind and to plan a full programme than rather individual studies one by one.

International regulations require Investigator's Brochures (IBs) to compile all available evidence that inform the risk-benefit assessment for the newly planned clinical trial. This study examined the adherence of IBs to the basic principles of evidence synthesis when compiling prior clinical studies.

For 97 IBs for phase I/II trials reviewed at one German research ethics committee we assessed the reporting on search, appraisal, and synthesis procedures for prior clinical studies. For a random subsample of 30 IBs, we evaluated the quality of reporting of the compiled 247 prior clinical studies.

Only 2% of all 97 IBs reported a comprehensive search strategy, provided a critical appraisal of the compiled prior clinical studies or presented respective study results in a structured manner. For the 247 prior clinical studies compiled in 30 IBs, the information required to appraise their risk of bias (eg, sample size calculation or baseline characteristics) was rarely reported.

When compiling all available evidence supporting the rationale for the proposed clinical study IBs do not acknowledge the broadly established principles for reviewing and reporting evidence. This may impact negatively on the trustworthiness and efficiency of risk-benefit assessment.

Viral and bacterial diseases seriously affect the artificial culture of S. chuatsi. As a carnivorous fish, artificial feed domestication is also an important means to improve the scale of S. chuatsi culture. Therefore, the study of immunology and digestive physiology is very important to the industrial development of S. chuatsi. In this work, we analyzed the expression and function of the S. chuatsi leukocyte cell-derived chemotaxin 2 (Sc-lect2) gene on a basis of next generation, single-molecule long-read sequencing. Sc-lect2 was mainly expressed in the liver but barely expressed in the gill, skin, muscle, kidney, head kidney, brain, stomach, and intestine. When the fish were infected with infectious spleen and kidney necrosis virus and challenged with lipopolysaccharide and polyinosinic-polycytidylic acid, Sc-lect2 expression significantly increased by about 40, 17, and 7-fold, respectively, compared with unstimulated samples. We also found that Sc-lect2 increases by approximately 8-fold after the fish are fed an artificial diet. These results show that mandarin fish liver can not only digest food but also express specific immune genes. Changes in the diet can cause the differential expression of Sc-lect2 genes. Four Sc-lect2 interaction genes were differentially expressed in the skin or blood. Interestingly, miR-145-3p could inhibit Sc-lect2 gene expression by targeting its coding sequence region. One CpG island in the promoter region showed a high level of methylation, suggesting that high methylation does not affect Sc-lect2 gene expression in the liver.This study was performed to determine effects of dietary isoleucine (Ile) on growth performance, and intestinal immunological and physical barrier function of hybrid catfish Pelteobagrus vachelli × Leiocassis longirostris. Six hundred and thirty fish (33.11 ± 0.09 g) were randomly divided into seven experimental groups with three replicates each, and respectively fed seven diets with 5.0, 7.5, 10.0, 12.5, 15.0, 17.5, and 20.0 g Ile kg-1 diets for 8 weeks. The results showed improvement of growth performance, feed intake, feed utilization, relative gut length (RGL), and intestinal fold height and width by dietary Ile (P less then 0.05). Meanwhile, dietary Ile (12.5 g kg-1 diet) improved the activities of lysozyme (LZM), acid phosphatase, alkaline phosphatase and the contents of complement 3 (C3), C4, and immunoglobulin M (IgM) (P less then 0.05). The c-type-lectin, c-LZM, g-LZM, and hepcidin mRNA expressions in the intestine were up-regulated in fish fed diets with 10.0-20.0 g Ile kg-1 diet (P less then ding to 32.05 g Ile kg-1 dietary protein. Collectively, dietary Ile improved growth performance and immunological and physical barrier function of intestine in hybrid catfish.
The prevalence of nonalcoholic fatty liver disease (NAFLD) is higher in women with polycystic ovarian syndrome (PCOS) than that in healthy women. This association can be explained in part by the resistance to insulin and the prevalence of obesity, which are fueled by high androgen levels. However, there is little evidence of the involvement of endogenous testosterone in hepatic steatosis in women with PCOS. Here, we treated Sprague Dawley rats with the aromatase inhibitor, letrozole, to increase the endogenous testosterone level and to decrease the estradiol levels. We also quantified the testosterone levels in human serum specimens and HepG2 cells to investigate the effects of androgens on hepatic steatosis and liver dysfunction.

Twenty-nine PCOS patients and twenty healthy women were enrolled. Alanine transaminase and aspartate transaminase (AST) levels were increased in women with PCOS, and a strong correlation between testosterone and AST levels was observed. After letrozole treatment for 90 days, rats were significantly more obese, with animals developing hepatic steatosis and moderate insulin resistance. Additional experiments revealed that excess androgen inhibited the AMP-activated protein kinase alpha pathway in letrozole-treated livers and dihydrotestosterone (DHT)-treated HepG2 cells, thereby causing steatosis.

Our results show that an elevated endogenous testosterone level can induce hepatic steatosis. Decreasing the endogenous testosterone level in hepatocytes may represent a new approach in the treatment of NAFLD in PCOS patients.

Similar effects for DZ and OX on the steroidogenesis were observed in the H295R experiment at therapeutically relevant concentrations. Progestagens and corticosteroids were increased up to 10 fold and androgens were decreased indicating CYP17A1 lyase inhibition. For DZ the inhibition on both the hydroxylase and lyase was confirmed by the recombinant CYP17A1 assay, whereas OX did not appear to directly affect the recombinant CYP17A1 enzyme. Androgens were decreased when exposing the H295R cells to AL, indicating a CYP17A1 lyase inhibition. However, this was not confirmed by the recombinant CYP17A1 assay but a down-regulation in gene expression was observed for StAR and CYP17A1. The present study showed that the three investigated benzodiazepines (BZDs) are rather potent endocrine disruptors in vitro, exerting endocrine effects close the therapeutic Cmax. Both direct and indirect effects on steroidogenesis were observed, but molecular modelling indicated no direct interactions between the heme group in the steroidogenic CYP enzymes and the unique diazepin structure. In contrast, physicochemical properties such as high log P, structure and molecular weight similar to that of steroids appeared to influence the endocrine disrupting abilities of the investigated pharmaceuticals in vitro. Docking of the three BZDs in CYP17A1 and CYP21A2 confirmed that shape complementarity and hydrophobic effects seem to determine the binding modes.
