Abstract
Background: Maudsley and Family-Based Therapies (MFT/FBT) are the current treatment of choice for adolescent AN based on positive outcomes that include weight restoration in around two-thirds of adolescents. Nevertheless around a quarter drop-out from treatment, particularly in the earlier phases, and a notable proportion of treated adolescents are reported to experience ongoing psychological distress during and post-treatment. This study explores the under-researched experiences of these adolescents. Method: Fourteen participants from Australia, New Zealand and the United Kingdom were interviewed about their experiences of MFT/FBT. An inductive thematic analysis of interview transcript data generated key themes related to their experiences, identity negotiations and the discursive materials these used to construct these. Results: The participants identified working as a family unit as key to their recovery, highlighting the importance of family therapy interventions for adolescent AN. However, they perceived an almost exclusive focus on weight restoration in the first phase of MFT/FBT was associated with experiences that included a relative neglect of their psychological distress and a loss of voice. Key within these experiences were processes whereby the adolescent engaged in identity negotiation and (re)claiming of their voice and implicit in their family standing with them in the treatment was that their life was worth saving. What was noted as most helpful was when therapists advocated and took into consideration their unique needs and preferences and tailored treatment interventions to these. Conclusions: There is a need to develop and research treatments that address, from the outset of treatment, the adolescents’ psychological distress (including as experienced in the context of their weight restoration). This should be with priority accorded to the adolescent’s voice and identity negotiations, as they and their families take steps to address the physical crisis of AN and in doing so, support more holistic and durable recovery.

Abstract
The gut microbiome and its interactions with epithelial and immune cells have wide-ranging effects on many aspects of human health. Thus, in vitro models that enable highly controlled studies of these interactions are of value, yet critical parameters enabling long term homeostasis between bacteria and mammalian cultures have not been established. In this study, we developed a model incorporating epithelial and immune cells as well as different bacterial species (B. fragilis, E. coli, L. rhamnosus, or R. gnavus) over a 50 hour culture period. Interestingly, both obligate and facultative anaerobes grew to similar extents in aerobic culture environments in co-culture with epithelial and immune cells, potentially due to measured microaerobic oxygen levels near the epithelial apical surface. It was demonstrated that bacteria elicited reactive oxygen species (ROS) production, and that these species heavily contribute to observed epithelial barrier damage in these static cultures. Introduction of a ROS scavenger significantly mitigated ROS-mediated damage, improving cell monolayer integrity and reducing lipid peroxidation, although not to control (bacteria-free culture) levels. These results indicate that monitoring and mitigating ROS concentrations can enable longer term bacteria-intestinal epithelial cultures, but also highlight the significance of additional factors that impact homeostasis in mammalian cell-bacteria systems.

Abstract
BackgroundTo assess the morphological features of persistent truncus arteriosus (PTA) on low-dose dual-source computed tomography (DSCT) and compare its diagnostic value for associated cardiovascular anomalies with that of transthoracic echocardiography (TTE).Methods:Twenty-four PTA patients were enrolled in this retrospective study. The types of PTA, diameters of the truncus artery (TA), main pulmonary artery (MPA), right pulmonary artery (RPA), left pulmonary artery (LPA), and ventricular septal defect (VSD) on DSCT were recorded. Besides, all associated cardiovascular abnormalities were assessed. The diagnostic performance of DSCT and TTE for associated anomalies were compared. The effective doses of DSCT were calculated.Results:Four types were found: type A1(n=13/24, 54.17%), type A2(n=7/24, 29.16%), type A3（n=3/24, 12.50%）and type A4(n=1/24,4.17%). The mean diameter of VSD, TA, MPA, RPA, and LPA was 1.47±0.56cm, 3.92±1.56cm, 2.27±1.65cm, 1.48±0.74cm and 1.38±0.66cm, respectively. 78 associated cardiovascular anomalies were confirmed. The most common associated abnormalities were VSD (100%), right-sided aortic arch (33.33%) and aortopulmonary collateral vessels (29.17%). Although TTE was better at diagnosing intracardiac anomalies (accuracy:99.17% vs. 95%; sensitivity: 97.06% vs. 88.24%; specificity: 100% vs. 97.67%), DSCT had an advantage in diagnosing the associated cardiovascular abnormalities (accuracy: 98.61% vs. 96.07%; sensitivity: 94.87% vs. 82.05%; specificity: 99.44% vs. 99.15%). The estimated mean effective doses was 0.98±0.37mSv (＜1mSv). Conclusions:Low-dose DSCT could accurately confirm the morphological features of PTA. Compared to TTE, low-dose DSCT is a better diagnostic tool for associated cardiovascular abnormalities. Combining with TTE will be beneficial to provide more accurate information for clinical interventions.

Abstract
Background: The filamentous fungus Trichoderma reesei is a widely used workhorse for cellulase production in industry due to its prominent secretion capacity of extracellular cellulolytic enzymes. However, some key components are not always sufficient in this cellulase cocktail, making the conversion of cellulose-based biomass costly on the industrial scale. Development of strong and efficient promoters would enable cellulase cocktail to be optimized for bioconversion of biomass.Results: In this study, a synthetic hybrid promoter was constructed and applied to optimize the cellulolytic system of T. reesei for efficient saccharification towards corncob residues. Firstly, a promoter library was established by sequence truncation based on the strong constitutive promoter Pcdna1. The strongest promoter amongst them was Pcdna1-3, exhibiting a 1.4-fold higher activity than that of the native cdna1 promoter. Meanwhile, the activation region (-821 to -622 bp upstream of the translation initiation codon ATG and devoid of the Cre1-binding sites) of the strong inducible promoter Pcbh1 was cloned and identified to be an amplifier in initiating gene expression. Finally, this activation region was fused to the strongest promoter Pcdna1-3, generating the novel synthetic hybrid promoter Pcc. This engineered promoter Pcc drove strong gene expression by displaying 1.6- and 1.8-fold stronger fluorescence intensity than Pcbh1 and Pcdna1 under the inducible condition using egfp as the reporter gene, respectively. Furthermore, Pcc was applied to overexpress the Aspergillus niger β-glucosidase BGLA coding gene bglA and the native endoglucanase EG2 coding gene eg2, achieving a 43.5-fold BGL activity and 1.2-fold EG activity increase, respectively. Ultimately, to overcome the defects of the native cellulase system in T. reesei, the bglA and eg2 were co-overexpressed under the control of Pcc promoter. The bglA-eg2 double expression strain QPEB70 exhibited a 178% increase in total cellulase activity, whose cellulase system displayed 2.3- and 2.4-fold higher saccharification efficiency towards acid-pretreated and delignified corncob residues than the parental strain, respectively.Conclusions: The synthetic hybrid promoter Pcc was generated and employed to improve the cellulase system of T. reesei by expressing specific components. Therefore, construction of synthetic hybrid promoters would allow particular cellulase genes to be expressed at desired levels, which is a viable strategy to optimize the cellulolytic enzyme system for efficient biomass bioconversion.

Abstract
BackgroundOxygen supplementation, although a cornerstone of emergency and cardiovascular medicine, often results in hyperoxia, a condition characterized by excessive tissue oxygen which results in adverse cardiac remodeling and subsequent injurious effects to physiological function. Cardiac remodeling is further influenced by various risk factors, including pre-existing conditions and sex. Thus, the purpose of this experiment was to investigate cardiac remodeling in Type I Diabetic (Akita) mice subjected to hyperoxic treatment. MethodsMale and female Akita and wild-type (WT) mice were divided into four groups based on gender and treatment, and were then subjected to either FiO2 > 90% (hyperoxia) for 72 h in an airtight chamber or normal air (normoxia). Physical, functional, and electrophysiological parameters were then evaluated. Finally, we employed correlational analysis and Multi-Way Analysis of Variance (ANOVA) which determined hyperoxia to have the greatest statistical influence on cardiac pathophysiology, followed by sex, and finally genotype.ResultsOverall, we demonstrated that Akita mice experience distinct challenges from wild type (WT) mice. Specifically, Akita males at both normoxia and hyperoxia showed significant decreases in body and heart weights, prolonged PR, QRS, and QTc intervals, and reduced %EF and %FS at normoxia compared to WT controls. Moreover, we found Akita males largely resemble female mice (both WT and Akita) with regards to the parameters studied. ConclusionsTaken together, our data suggest that Type I diabetic patients may have distinct cardiac pathophysiology under hyperoxia compared to uncomplicated patients, with males being at high risk. These findings can be used to enhance the provision of care in ICU patients with Type I diabetes as a comorbid condition.

Abstract
Objectiveto investigate the expression of Wnt10b, Rankl, β-catenin and Runx2 mRNA in periodontal tissues during orthodontic tooth movement (OTM) in rats; Materials and methods36 healthy male SD rats were selected and divided into six groups randomly according to the time of the force applied (0 hour, 12 hours, 24 hours, 5 days, 7 days, 14 days), with 6 rats in each group. 0hour group served as the control group. Except for control group, an orthodontic force of 50g was applied to the upper-left first molar with a nickel-titanium tension spring. The expression of Wnt10b, Rankl, β-catenin and Runx2 during OTM were detected by Real-time PCR (RT-PCR). ResultsCompared with the control group, Wnt10b mRNA expression in the pressure side was inhibited at the initial stage, and then increased, reached peak at day 5. A strong expression of Rankl mRNA in the pressure side can be seen from 12 hours to 14 days. The expression level was consistently higher than control group, and it peaked at day 7. The initial expression of β-catenin and Runx2 mRNA in the periodontal tissues of the experimental groups were small in the tension side, but still higher than the control group. The expression increased gradually with the extension of time, and reached the peak at day 7 after force treatment. ConclusionWnt10b, β-catenin, Rankl and Runx2 are related to periodontal tissues remodeling during OTM in rats; Wnt10b/β-catenin signaling pathways participate in periodontal tissue remodeling during OTM.

Abstract
Rice is the staple food for half of the world’s population. Starch accounts for 80-90% of the total mass of rice seeds, and rice starch is low in resistant starch (RS) with a high glycemic index (GI). RS has gained important since it is beneficial in preventing various diseases. Starch branching enzyme IIb (SBEIIb) plays a key role in the amylopectin synthesis pathway in the endosperm of cereals. Down-regulation of SBEIIb in several important crops has led to high amylose, high RS and low GI starch. In this study, we mutated OsSBEIIb in the japonica rice cultivar TNG82 through CRISPR/Cas9 and investigated the molecular and physicochemical modifications in OsSBEIIb mutant lines, e.g., gene expression, enzyme activity, apparent amylose content (AAC), RS and GI. As expected, the levels of modification in these starch related traits in heterozygous mutant lines were about half as those of homozygous mutant lines. Gene expression and enzyme activity of OsSBEIIb were down-regulated significantly while AAC and RS contents increased progressively from 17.4% and 0.5% in WT, respectively, to as high as 25.0% and 7.5% in heterozygous mutant lines and 36.0% and 12.0% in homozygous mutant lines. Consequently, with increased RS and decreased rate of reducing sugar production, GI progressively decreased in heterozygous and homozygous mutant rice endosperms by 11% and 28%, respectively. Our results demonstrate that it has huge potential for precise and efficient generation of high RS and low GI rice through CRISPR/Cas9 to provide a more suitable source of starch for type II diabetes.

Abstract
Background: As an alpine plants，Rhododendron chrysanthum (R. chrysanthum) has evolved cold resistance mechanisms and become a valuable plant resource with the responsive mechanism of cold stress. Results: In my study, we adopt the phosphoproteomic and proteomic analysis combining with physiological measurement to illustrate the responsive mechanism of R. chrysanthum seedling under cold (4℃) stress. After chilling for 12 h, 350 significantly changed proteins and 274 significantly changed phosphoproteins were detected. COG analysis showed that significantly changed proteins and phosphoproteins were mainly involved in signal transduction and energy production and conversion under cold stress. The results indicated photosynthesis was inhibited under cold stress, but cold induced calcium-mediated signaling, reactive oxygen species (ROS) homeostasis and other transcription regulation factors could protect plants from destruction caused by cold stress. Conclusions: These data constitute a cold stress-responsive metabolic atlas in R. chrysanthum, which will springboard further investigations into the complex molecular mechanisms of plant cold adaptation.

Abstract
BackgroundHeart failure (HF) has become a healthcare challenge worldwide. Recently, certain trials on sodium-glucose co-transporter-2 (SGLT2) inhibitor showed benefits for patients with HF. This study aimed to systematically review the literature and investigate the clinical efficacy of SGLT2 inhibitors in cardiovascular events among patients with and without HF. Methods We searched randomized controlled trials (RCTs) in PubMed, Cochrane databases, Embase, and ClinicalTrials.gov registry form inception to October 2020. Dichotomous variables were pooled using a random-effects model and presented with a risk ratio (RR) and 95% confidence interval (CI). Subgroup meta-analyses were carried out by high/low SGLT2/SGLT1 selectivity and individual SGLT2 inhibitor.ResultsA total of 10 RCTs comprised of 52,607 patients were eligible for the analyses. SGLT2 inhibitors reduced the risk of total cardiovascular death or hospitalization for HF (RR 0.79, [95% CI: 0.74 to 0.84]; p < 0.01, I2 = 31%). Apart from stroke, SGLT2 inhibitors contributed to a risk reduction in major adverse cardiovascular events (MACE, RR 0.93, [95% CI: 0.88 to 0.99]; p = 0.03, I2 = 0), all-cause mortality (RR 0.92, [95% CI: 0.85 to 0.99]; p = 0.03, I2 = 0), cardiovascular death (RR 0.91, [95% CI: 0.83 to 0.99]; p = 0.03, I2 = 0), hospitalization for HF (RR 0.72, [95% CI: 0.66 to 0.79]; p < 0.01, I2 = 0), and myocardial infarction (RR 0.89, [95% CI: 0.80 to 0.99]; p = 0.03, I2 = 0). For HF patients, SGLT2 inhibitors had more clinical benefits in terms of all-cause mortality and cardiovascular death, while advantages were observed in MACE and myocardial infarction for non-HF patients. Furthermore, SGLT2 inhibitors with low SGLT2/SGLT1 selectivity have better efficacy for hospitalization of HF, compared with high-selectivity inhibitors (RR 0.51 [95% CI: 0.35-0.75] versus 0.73 [95% CI: 0.66-0.81] for HF patients). ConclusionsSGLT2 inhibitors significantly mitigate hospitalization for HF. Between HF and non-HF populations, this regimen reduce mortality for HF patients and improve MACE and myocardial infarction for non-HF patients. The SGLT2 inhibitor, mixed with the effect of SGLT1 inhibitors, may lead to a lower risk of hospitalization for HF.

Abstract
Background: The aim of this study was to investigate the co-operative role of CXCR4/ CXCL12 axis and IL-1Ra in metastatic processes mechanism by interactions between colorectal cancer cells and stromal cells in their microenvironment. Methods: Expression of IL-1a, CXCL12 and CXCR4 mRNA and proteins were determined by RT-PCR and Western blot. The effect of secreted level of CXCL12 by IL-1Ra on fibroblasts was measured by ELISA. CXCL12 regulate metastatic potential of colorectal cancer was evaluated by proliferation, invasion and angiogenesis assays, respectively, in which invasion and angiogenesis assays used an in vitro system consisting of co-cultured colorectal cells and stromal cells. Results: IL-1a was expressed in high liver metastatic colorectal cancer cell lines (HT-29 and WiDr). The colorectal cancer cell-derived IL-1a and rIL-1a significantly promoted CXCL12 expression by fibroblasts, and this enhancing effect can be significantly inhibited by IL-1Ra (P<0.01). CXCL12 not only enhanced the migration and proliferation of human umbilical vein endothelial cells (HUVECs), but also significantly enhanced angiogenesis (P<0.01). Furthermore, the high liver-metastatic colorectal cancer cell line (HT-29), which secretes IL-1a, significantly enhanced angiogenesis compared to the low liver-metastatic cell line (CaCo-2), which does not produce IL-1a (P<0.01). On the contrary, IL-1Ra can significantly inhibit migration, proliferation and angiogenesis (P<0.01). Conclusion: Autocrine IL-1a and paracrine CXCL12 co-enhances the metastatic potential of colorectal cancer cells; IL-1Ra can inhibit the metastatic potential of colorectal cancer cells via decrease IL-1a/CXCR4/CXCL12 signaling pathways.

Abstract
Background: Evidence of the efficacy and safety of semaglutide among patients with type 2 diabetes who were initiated on or were switched to semaglutide from other GLP-1 RAs remains limited. The objective of this study was to investigate the short-term effects of switching to semaglutide from other GLP-1 RAs.Methods: This retrospective cohort study evaluated patients with type 2 diabetes who were initiated on or were switched to semaglutide due to poor diabetes control with other GLP-1 RAs or other medications, or obesity. HbA1c, body weight, serum creatinine, serum uric acid, parameters of lipid metabolism, and parameters of liver function were measured before and 6 months after administration of semaglutide.Results: A total of 50 patients were registered: 21 men and 29 women, aged 51.3 years. Mean body mass index was 32.2 kg/m2, and serum C-peptide was 2.7mg/mL. After switching to semaglutide (n=43), HbA1c and body weight significantly decreased from 6.72 % to 6.22 % and from 86.5 kg to 82.7 kg, respectively. The same findings were observed in semaglutide-naïve patients (n=7). Serum uric acid, total cholesterol, triglycerides, and urinary albumin-creatinine ratio decreased significantly as well, whereas serum creatinine did not change significantly. Conclusion: Semaglutide showed excellent efficacy, even in patients switched from other GLP-1 RAs. Semaglutide appears to be a promising agent for blood glucose and body weight control in obese type 2 diabetes mellitus patients and could be more potent in treating type 2 diabetes than existing GLP-1 RAs.
