Direct conversion of human endothelial cells to hepatic progenitor cells
Authors: Inada Hiroki , Udono Miyako , Suzuki Atsushi
Published: October 2020

This protocol describes direct lineage reprogramming of human endothelial cells isolated from the umbilical vein and peripheral blood into hepatic progenitor cells. These induced human hepatic progenitor cells (hiHepPCs) proliferate in long-term culture and give rise to hepatocytes and cholangiocytes as descendants. To induce hiHepPCs from endothelial cells, we first established an efficient culture condition, enabling hiHepPC generation and propagation in a monolayer culture. Then, we confirmed the ability of the hiHepPCs to differentiate into mature hepatocytes by formation of cell aggregates in each well of ultra-low attachment 96-well plates. Furthermore, upon culturing in Matrigel, the hiHepPCs differentiated into cholangiocytes and formed cystic epithelial spheroids, similar to human liver-derived cholangiocytes. Direct induction of the expandable and bipotential human hepatic progenitor cells provides a possibility for generating cells such as hepatocytes and cholangiocytes, which will be useful for developing therapeutic strategies for human liver diseases.

Published: October 2020

BACKGROUND: The molecular pathogenesis of endometrial cancer is not completely understood. CypB upregulated in many cancers, however, its role in endometrial carcinoma has not been studied. Here, we determine the effect of CypB on the growth of endometrial cancer. METHODS: In this study, we examined the expression of CypB in endometrial cancer tissues using immunohistochemistry. CypB silenced in HEC-1-B cell line by shRNA. CCK-8, colony formation assays, wound healing assays, and transwell analysis were performed to assess its effect on tumor cell proliferation and metastasis . Furthermore, microarray analysis was carried out to compare the global mRNA expression profile between the HEC-1-B and CypB-silenced HEC-1-B cells. Gene ontology and KEGG pathway enrichment analysis were performed to determine the potential function of differentially expressed genes related to CypB. RESULTS: We found that CypB was upregulated in endometrial cancer, inhibit CypB expression could significantly suppress cell proliferation, metastasis, and migration. We identified 1536 differentially expressed genes related to CypB (onefold change, p< 0.05), among which 652 genes were upregulated and 884 genes were downregulated. The genes with significant difference in top were mainly enriched in the cell cycle, glycosphingolipid biosynthesis, adherens junctions, and metabolism pathways. CONCLUSIONS: The results of our study suggest that CypB may serve as a novel regulator of endometrial cell proliferation and metastasis, thus representing a novel target for gene-targeted endometrial therapy.Trial registration: YLYLLS [2018] 008.

Background: At present, the role of protected areas has been expanded into climate change mitigation action, specifically on Reducing Emissions from Deforestation and Forest Degradation (REDD+). Reliable and practical method for measuring, reporting and verifying carbon stock is an essential component for REDD+. This study aims at recognizing the characteristic and estimating aboveground forest carbon stock in the tropical protected area using a combination of terrestrial forest inventory and spatial data. Results: In the study area of Bukit Tigapuluh National Park in Central Sumatra, 168 cluster plots totaling 33.6 hectares were taken proportionally based on the percentage of forest cover types (dryland primary natural forest/DPF and dryland secondary natural forest/DSF) using a traditional forest inventory method (more than 5 cm dbh) in combination with the application of information technology. Results showed that Bukit Tigapuluh National Park secured a significant aboveground forest carbon stock which has been estimated to be 269.2 + 22.2 tC/ha or 35,823,639 + 2,951,071 tC in total, being sequestered in approximately 133,051 hectares of tropical rain forest. This result was higher than other studies located in non-protected areas, but slightly lower than other studies within protected area.Conclusion: This finding supported the argument that protected areas possess higher figure of aboveground carbon stock compared to other forest management units. High amount of forest carbon biomass in the protected areas shall be very important assets for conducting the role of conservation for REDD+.

Published: October 2020

Background: A variety of DNA-based methods have been applied to identify genetic markers of attention deficit hyperactivity disorder (ADHD), but the connection to RNA-based gene expression has not been fully exploited. Methods: Using well defined cohorts of discordant, monozygotic twins from the Michigan State University Twin Registry, and case-controlled ADHD cases in adolescents, the present studies utilized advanced single molecule RNA sequencing to identify expressed changes in whole blood RNA in ADHD. Multiple analytical strategies were employed to narrow differentially expressed RNA targets to a small set of potential biomarkers of ADHD. Results: RNA markers common to both the discordant twin study and case-controlled subjects further narrowed the putative targets, some of which had been previously associated with ADHD at the DNA level. The potential role of several differentially expressed genes, including ABCB5, RGS2, GAK, GIT1 and 3 members of the galactose metabolism pathway (GALE, GALT, GALK1) are substantiated by prior associations to ADHD and by established mechanistic connections to molecular pathways relevant to ADHD and behavioral control.Conclusions: The convergence of DNA, RNA, and metabolic data suggests these may be promising targets for diagnostics and therapeutics in ADHD.

Published: October 2020

Background: To investigate the difference in retinal nerve fiber layer (RNFL) thickness, choroidal thickness (CT) and superficial retinal vessels between thyroid-associated ophthalmopathy (TAO) patients and healthy controls. To identify the potential influencing factors for these parameters and evaluate their diagnostic abilities in TAO.Methods: 20 active TAO patients, 33 inactive TAO patients and 29 healthy participants were enrolled. TAO patients were divided according to the clinical activity score (CAS). RNFL thickness and CT were measured by HD-OCT, while foveal avascular zone (FAZ), vascular density and perfusion density were measured by optical coherence tomography angiography (OCTA). SPSS software was used for statistical analysis.Results: Active TAO patients had thinner RNFL thickness than the other two groups (P<0.001, P<0.001). Both active and inactive TAO patients had significantly higher CT in the macular region (all P<0.05). The FAZ area in the active TAO group was significantly larger than the other two groups (P=0.045, P=0.001). The inactive TAO group had significantly higher vascular density than the other two groups (all P<0.05). With regard to the perfusion density, significant differences were observed in the temporal and inferior areas (P=0.045, P=0.001), as well as the average values (P=0.032). The FAZ area was positively correlated with intraocular pressure (r=0.274, P=0.013), while it was negatively correlated with axial length (r=-0.344, P=0.002). The vascular density and perfusion density were not significantly correlated with different clinical variables (all P>0.05). The AUC analysis indicated these parameters also exhibited a significant discriminatory power in TAO diagnosis.Conclusions: TAO patients had significant variations in RNFL thickness, choroidal thickness, FAZ area and superficial retinal vessels. These parameters appeared to be potential adjuncts in the evaluation of TAO patients.

Published: October 2020

Background: Globally, endometrial cancer is the fourth most common malignant tumor in women and the number of women being diagnosed is increasing. Tumor progression is strongly related to the cell survival-promoting functions of autophagy. We explored the relationship between endometrial cancer prognoses and the expression of autophagy genes using human autophagy databases.Methods: The Cancer Genome Atlas was used to identify autophagy related genes (ARGs) that were differentially expressed in endometrial cancer tissue compared to healthy endometrial tissue. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes were referenced to identify important biological functions and signaling pathways related to these differentially expressed ARGs. A prognostic model for endometrial cancer was constructed using univariate and multivariate Cox, and Least Absolute Shrinkage and Selection Operator regression analysis. Endometrial cancer patients were divided into high- and low-risk groups according to risk scores. Survival and receiver operating characteristic (ROC) curves were plotted for these patients to assess the accuracy of the prognostic model. Using immunohistochemistry the protein levels of the genes associated with risk were assessed.Results: We determined 37 ARGs were differentially expressed between endometrial cancer and healthy tissues. These genes were enriched in the biological processes and signaling pathways related to autophagy. Four ARGs (CDKN2A, PTK6, ERBB2 and BIRC5) were selected to establish a prognostic model of endometrial cancer. Kaplan–Meier survival analysis suggested that high-risk groups have significantly shorter survival times than low-risk groups. The area under the ROC curve indicated that the prognostic model for survival prediction was relatively accurate. Immunohistochemistry suggested that among the four ARGs the protein levels of CDKN2A, PTK6, ERBB2, and BIRC5 were higher in endometrial cancer than healthy endometrial tissue.Conclusions: Our prognostic model assessing four ARGs (CDKN2A, PTK6, ERBB2, and BIRC5) suggested their potential as independent predictive biomarkers and therapeutic targets for endometrial cancer.

Published: October 2020

Background: The incidence of pertussis shows an increasing trend in recent years, but some clinicians often lack sufficient understanding of the clinical characteristics and risk factors for severe pertussis, and more effective measures should be taken to reduce the incidence and mortality of pertussis in young infants.Methods: A retrospective study was conducted, and 184 infants and children with pertussis who had been hospitalized in the Department of Pediatrics of Beijing Ditan Hospital affiliated with Capital Medical University from January 2016 to December 2017 were included. Clinical data of the patients were collected and the clinical characteristics were statistically analyzed.Results: Among the 184 patients, 41.85% were infants < 3 months of age, and 65.22% of the total patients were not vaccinated against pertussis. There were 22 critically ill children, among whom 4 died, and compared with mild cases, they had a higher proportion of children younger than 3 months of age and infants not vaccinated against pertussis (63.64% vs. 38.89% and 100% vs. 60.49%, respectively); a higher proportion of children with severe pneumonia (100% vs. 0%); higher leukocyte count(× 109/L , 35.80 ± 20.53 vs 19.41 ± 8.59); and a higher proportion of children with severe hyperleukocytosis (18.18% vs. 0%, respectively) (P<0.05).Conclusions: 1. Infants aged <3 months not vaccinated for pertussis appear more likely to become infected and have more severe disease. 2. Severe pneumonia and hyperleukocytosis are the main mechanisms underlying severe pertussis.

Published: October 2020

Background: Although medical intervention of periprosthetic bone loss in the immediate postoperative period was recommended, not all the patients experienced periprosthetic bone loss after total hip arthroplasty (THA). Prediction tools that enrolled all potential risk factors to calculate an individualized prediction of postoperative periprosthetic bone loss were strongly needed for clinical decision-making. Methods: Data of the patients underwent primary unilateral cementless THA between April 2015 and October 2017 in our center were retrospectively collected. Candidate variables included demographic data and bone mineral density (BMD) in spine, hip and periprosthetic regions that measured 1 week after THA. Outcomes of interest included the risk of postoperative periprosthetic bone loss in Gruen zone 1, 7 and total zones in the 1st postoperative year. Nomograms were presented based on multiple logistic regressions via R language. 1000 Bootstraps were used for internal validation. Results: 563 patients met the inclusion criteria were enrolled, and the final analysis was performed in 427 patients (195 male and 232 female) after the exclusion. The mean BMD of Gruen zone 1, 7, and total were decreased by 4.1%, 6.4%, and 1.7% at the 1st year after THA, respectively. 61.1% of the patients (261/427) experienced bone loss in Gruen zone 1 at the 1st postoperative year, while there were 58.1% (248/427) in Gruen zone 7 and 63.0% (269/427) in Gruen zone total. Bias-corrected c-index for risk of postoperative bone loss in Gruen zone 1, 7 and total zones in the 1st postoperative year were 0.700, 0.785, and 0.696, respectively. The most highly influential factors for the postoperative periprosthetic bone loss were primary diagnosis and BMD in the corresponding Gruen zones at the baseline. Conclusions: To the best of our knowledge, our study represented the first time to use the nomograms in estimating the risk of postoperative periprosthetic bone loss with adequate predictive discrimination and calibration. Those predictive models would help surgeons to identify high-risk patients who may benefit from anti-bone-resorptive treatment on the early postoperative period effectively. It is also beneficial for patients, as they can choose the treatment options based on a reasonable expectation following surgery.

Published: October 2020

Background: Since December 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged as a novel etiologic agent of viral pneumonia. We aimed to compare clinical features of 165 Italian patients with laboratory confirmed or unconfirmed 2019-nCoV pneumonia. Methods: On March 31 2020, hospitalized patients who presented with fever and/or respiratory symptoms, exposures, and presence of lung imaging features consistent with 2019-nCoV pneumonia, were included. Before admission to a hospital ward, patients underwent RT-PCR based SARS-CoV-2 RNA detection in their nasopharyngeal swab samples. Results: Of 165 patients studied, 119 had positive RT-PCR results and 46 were RT-PCR negative for two days or longer (i.e., when the last swab sample was obtained). The median age was 70 years (IQR, 58–78), and 123 (74.6%) of 165 patients had at least one comorbidity. The majority of patients (101/165, 61.2%) had a mild pneumonia, and the remaining patients (64/165, 38.8%) a severe/critical pneumonia. We did not find any substantial difference in symptoms, incubation periods, and radiographic/CT abnormalities as well as in many of the biological abnormalities recorded. However, at multivariable analysis, higher concentrations of hemoglobin (OR, 1.34; 95% CI, 1.11‒1.65; P = 0.003) and lower counts of leukocytes (OR, 0.81; 95% CI, 0.72‒0.90; P <0.001) were statistically associated with confirmed COVID-19 diagnosis. While mortality rates were similar, patients with confirmed diagnosis were more likely to receive antivirals (95% vs 19.6%, P <0.001) and to develop ARDS (63% vs 37%, P = 0.003) than those with unconfirmed COVID-19 diagnosis. Conclusions: Our findings suggest that unconfirmed 2019-nCoV pneumonia cases may be actually COVID-19 cases and that clinicians should be cautious when managing patients with presentations compatible with COVID-19.

Published: October 2020

[Background] AminoIndexTM Cancer Screening (AICS (lung)) was developed as a screening test for lung cancer using a multivariate analysis of plasma-free amino acid (PFAA) profiles. According to the developed index composed of PFAA, the probability of lung cancer was categorized into AICS (lung) ranks A, B, and C in order of increasing risk. The aim of the present study was to investigate the relationship between the preoperative AICS (lung) rank and surgical outcomes in patients who underwent curative resection for non-small cell lung cancer (NSCLC).[Methods] Preoperative blood samples were collected from 297 patients who underwent curative resection for NSCLC between 2006 and 2015. PFAA concentrations were measured. The relationship between the preoperative AICS (lung) rank and clinicopathological factors was examined. The effects of the preoperative AICS (lung) rank on postoperative outcomes were also analyzed.[Results] The AICS (lung) rank was A in 93 patients (31.3%), B in 82 (27.6%), and C in 122 (41.1%). The AICS (lung) rank did not correlate with any clinicopathological factors, except for age. Based on follow-up data (median follow-up period of 6 years), postoperative recurrence was observed in 22 rank A patients (23.7%), 15 rank B (18.3%) and 49 rank C (40.2%). In the univariate analysis, preoperative AICS (lung) rank C was a worse factor of recurrence-free survival (p=0.0002). The multivariate analysis identified preoperative AICS (lung) rank C (HR: 2.17, p=0.0005) as a significant predictor of postoperative recurrence, particularly in patients with early-stage disease or adenocarcinoma.[Conclusion] Preoperative AICS (lung) rank C is a high-risk predictor of postoperative recurrence in patients undergoing curative resection for NSCLC.

Published: October 2020

Background: Minimally invasive liver resections (MILRs) have been increasingly performed in recent years. However, the majority of MILRs are actually minor or limited resections of peripheral lesions. Due to the technical complexity major hepatectomies remain challenging for minimally invasive surgery. The aim of this study was to compare the short and long-term outcomes of patients undergoing minimally invasive right hepatectomies (MIRHs) with contemporary patients undergoing open right hepatectomies (ORHs). Methods: Consecutive patients submitted to anatomic right hepatectomies between January 2013 and December 2018 in two tertiary referral centers were studied. Study groups were compared on an intention-to-treat basis after propensity score matching (PSM). Overall survival (OS) analyses were performed for the entire cohort and specific etiologies subgroups. Results: During study period 178 right hepatectomies were performed. After matching, 37 patients were included in MIRH group and 60 in ORH group. The groups were homogenous for all baseline characteristics. MIRHs had significant lower blood loss (400 ml vs. 500 ml, P=0.01), lower rate of minor complications (13.5% vs. 35%, P=0.03) and larger resection margins (10 mm vs. 5 mm, P=0.03) when compared to ORHs. Additionally, a non-significant decrease in hospital stay (ORH 9 days vs. MIRH 7 days, P=0.09) was observed. No differences regarding the use of Pringle’s maneuver, operative time, overall morbidity or perioperative mortality were observed. OS was similar between the groups (P=0.13). Similarly, no difference in OS was found in subgroups of patients with primary liver tumors (P=0.09) and liver metastasis (P=0.80). Conclusions: MIRHs are feasible and safe in experienced hands. Minimally invasive approach was associated with less blood loss, a significant reduction in minor perioperative complications, and did not negatively affect long-term outcomes.

Published: October 2020

Background The study aimed to evaluate the outcomes following the implementation of enhanced recovery after surgery (ERAS) for patients undergoing lung cancer surgery.Method A retrospective cohort study involving 1,749 patients with lung cancer undergoing pulmonary resection was conducted. The patients were divided into two time period groups for analysis(routine pathway and ERAS pathway). Logistic regression analysis was performed to assess the risks of developing postoperative pulmonary complications.Results Among the 1,749 patients, 691 were stratified into the ERAS group, and 1,058 in to the routine group. The ERAS group presented with shorter postoperative in-hospital length of stay (LOS) (4.0 vs 6.0, P<0.001), total LOS (10.0 VS. 13.0 days, P<0.001), and lower total in-hospital costs (P<0.001), including material (P<0.001) and drug expenses (P<0.001). Furthermore, the ERAS group also presented with a lower occurrence of postoperative pulmonary complications (PPCs) than the routine group (15.2% vs. 19.5%, P=0.022). Likewise, a significantly lower occurrence of pneumonia (8.4% vs. 14.2%, P<0.001) and atelectasis (5.9% vs. 9.8%, P=0.004) was found in the ERAS group. Regarding the binary logistic regression, the ERAS intervention was the sole independent factor for the occurrence of PPCs (OR: 0.601, 95% CI: 0.434-0.824, P=0.002). In addition, age (OR: 1.032, 95% CI: 1.018-1.046), COPD (OR: 1.792, 95% CI: 1.196-2.686), and FEV1(OR: 0.205, 95% CI: 0.125-0.339) were also independent predictors of PPCs. Conclusion Implementation of an ERAS pathway shows improved postoperative outcomes, including shortened LOS, lower in-hospital costs, and reduced occurrence of PPCs, providing benefits to the postoperative recovery of patients with lung cancer undergoing surgical treatment.

Published: October 2020

Background: Sarcopenia is a syndrome characterized by progressive and systemic decreases in skeletal muscle mass and muscle strength. The influence or prognosis of various liver diseases in this condition have been widely investigated, but little is known about whether sarcopenia and/or muscle mass loss are related to minimal hepatic encephalopathy (MHE).Methods: To clarify the relationship between MHE and sarcopenia and/or muscle mass loss in patients with liver cirrhosis.Methods: Ninety-nine patients with liver cirrhosis were enrolled. MHE was diagnosed by a neuropsychiatric test. Skeletal mass index (SMI) and Psoas muscle index (PMI) were calculated by dividing skeletal muscle area and psoas muscle area at the third lumbar vertebra by the square of height in meters, respectively, to evaluate muscle volume.Results: This study enrolled 99 patients (61 males, 38 females). MHE was detected in 48 cases (48.5%) and sarcopenia in 6 cases (6.1%). Patients were divided into two groups, with or without MHE. Comparing groups, no significant differences were seen in serum ammonia concentration or rate of sarcopenia. SMI was smaller in patients with MHE (46.4 cm2/m2) than in those without (51.2 cm2/m2, P = 0.027). Similarly, PMI was smaller in patients with MHE (4.24 cm2/m2) than in those without (5.53 cm2/m2, P = 0.003). Skeletal muscle volume, which is represented by SMI or PMI was a predictive factor related to MHE (SMI ≥ 50 cm2/m2; odds ratio 0.300, P = 0.002, PMI ≥ 4.3 cm2/m2; odds ratio 0.192, P = 0.001).Conclusions: Muscle mass loss was related to minimal hepatic encephalopathy, although sarcopenia was not. Measurement of muscle mass loss might be useful to predict MHE.

Published: October 2020

BackgroundWith the mature application of laparoscopy in hepatobiliary surgery, laparoscopic treatment of hepatic cystic echinococcosis(CE) has made certain progress. But, due to the inherent limitations of laparoscopy and the growth characteristics of cystic echinococcosis, distinguishing the boundary between cystic lesion and normal hepatic parenchyma is pivotal importance for successful sugery. Indocyanine green(ICG) fluorescence imaging technology can view the boundary of lesion and normal tissue during the treatment of hepatic cystic echinococcosis. Applied laparoscopy combined with ICG fluorescence imaging technique for hepatic cystic echinococcosis may be an effective surgical strategy.MethodsThe clinical data contained nine patients with hepatic cystic echinococcosis who underwent laparoscopic surgery with indocyanine green fluorescence imaging technique in authors’ institution from December 2018 to December 2019 were retrospectively analyzed. Indocyanine green was administered intravenously three days prior to surgery. The fluorescence acquisition system for real-time imaging was used during the surgery and the patients were followed up after surgery.ResultsOf reported nine patients, six are male and the remaining three are female. The average age is (36.4 ± 7.6) years. For all subjects, surgical procedures were performed under laparoscopy with indocyanine green fluorescence system. This technique showed the clear boundary of the hepatic cyst with normal liver paranchyma. Total cystectomy in six patients, subtotal cystectomy in two patients and partial hepatectomy in one patient were performed repectively. The average operation time was 3.8 ± 0.9 hours, blood loss 206.0 ± 120.7 ml. Neither blood transfusion nor post-operative complication was experienced. The average abdominal drainage time was 3.4 ± 0.9 days with hospital stay 5.7 ± 2.1 days. During the 6-12 months follow-up period, neither recurrence nor intraperitoneal implantation was found.ConclusionsApplied laparoscopy combined with ICG fluorescence imaging technique for hepatic cystic echinococcosis is safe and feasible. Enhanced boundary image can assist surgeons to complete radical resection and reduce complications.
Inhibitory effects of Camellia japonica on cell inflammation and acute rat reflux esophagitis
Authors: Nam Hyeon Hwa , Nan Li , Choo Byung Kil
Published: October 2020

Background: Oxidative stress and inflammation are the causes of many diseases. Reflux esophagitis (RE) is a common gastroesophageal reflux disease with a continuous upward trend in incidence worldwide. Camellia japonica (C. japonica) has long been used as a traditional herbal hemostatic medicine in China and Korea. The purpose of this study was to explore the anti-oxidant and anti-inflammatory activities of C. japonica and its protective effect against RE.Materials and methods: Buds from C. japonica plants were collected in a mountainous area of Jeju, South Korea. Dried C. japonica buds were extracted with 75% ethanol. DPPH and ABTS radical scavenging assays were performed. The ROS production and anti-inflammatory effects of C. japonica bud ethanol extract (CJE) on LPS-induced RAW264.7 cell inflammation were evaluated. The protective effects of CJE on RE were investigated in a RE rat model. Results: CJE eliminated over 50% of DPPH and ABTS radicals at concentrations of 100 and 200 μg/mL, respectively. CJE alleviated changes in cell morphology, reduced production of ROS, NO and IL-1β and down-regulated expression levels of iNOS, TNF-α, phosphorylated NF-κB, IκBα, and JNK/p38/MAPK. CJE reduced the esophageal tissue damage ratio (40.3%) and attenuation of histological changes. In addition, CJE down-regulated expression levels of TNF-α, IL-1β, and COX-2 and phosphorylation levels of NF-κB and IκBα in esophageal tissue. Conclusions: CJE possesses good anti-oxidation and anti-inflammatory activity, and can reduce RE damage in rats caused by gastric acid reflux. Therefore, CJE is a natural material that may be a candidate phytomedicine for the treatment of RE.

Background: Soil fungi play crucial roles in ecosystem functions. However, how snow cover change associated with winter warming affects soil fungal communities remains unclear in the Tibetan forest.Methods: We conducted a snow manipulation experiment to explore immediate and legacy effects of snow exclusion on soil fungal community diversity and composition in a spruce forest on the eastern Tibetan Plateau. SoilThe fungal communities were performed by the high throughput sequencing of gene-fragments amplified from forest soil DNA.Results: We found that the Ascomycota and Basidiomycota were the two dominant fungal phyla and Archaeorhizomyces, Aspergillus and Amanita were the three most common genera across seasons and snow manipulations. Snow exclusion did not affect the diversity and structure of soil fungal community in both snow-covered and snow-free seasons. However, the relative abundance of some fungal communities was different among seasons. Soil fungal groups were correlated with environmental factors (i.e., temperature and moisture) and soil biochemical variables (i.e., ammonium and enzyme).Conclusions: These results suggest that the season-driven variations had stronger impacts on soil fungal community than short-term snow cover change. Such findings may have important implications for soil microbial processes in Tibetan forests experiencing significant decreases in snowfall.

BackgroundHaemodialysis can negatively impact quality of life and mental health. Arts-based interventions used successfully in other settings to improve health and well-being, could help address the impact of haemodialysis. This study aimed to evaluate the feasibility and acceptability of conducting a randomised controlled trial (RCT) of an arts-based intervention for patients receiving haemodialysisMethodsA parallel convergent mixed-methods design was used, including a pilot cluster RCT and qualitative process evaluation. Phase 1 evaluated recruitment and retention rates through a pilot cluster RCT at a single haemodialysis unit in Northern Ireland. Participants included patients who received haemodialysis for ESKD, were over the age of 18 and had the capacity to consent. These participants were randomised to the intervention or control group according to their haemodialysis shift. The intervention involved six one-hour, one-to-one facilitated arts sessions during haemodialysis. Phase 2 explored intervention and trial acceptability through a qualitative process evaluation using semi-structured interviews based on the RE-AIM framework. Participants included 13 patients who participated in phase 1 of the study, including 9 participants from the experimental group and four participants from the control group, and nine healthcare professionals who were present on the unit during implementation. Results:Out of 122 outpatient haemodialysis patients, 94 were assessed as eligible for participation. Twenty-four participants were randomised, meaning 80% of the target sample size was recruited and the attrition rate at 3 months was 12.5% (n=3). Participants viewed the arts as more accessible and enjoyable than anticipated following implementation. All participants who started the intervention (n=11) completed the full six sessions. Qualitative benefits of the intervention suggest improvements in mental well-being. Patient choice and facilitation were important factors for successful implementation. Conclusion:An arts-based intervention for patients receiving haemodialysis is acceptable for both patients and healthcare professionals, and a definitive trial is feasible. The intervention may help improve mental-wellbeing in patients receiving haemodialysis, but this requires further investigation in a definitive trial.Trial registrationThe trial was prospectively registered on clinicaltrials.gov on 14/8/2018, registration number NCT03629496.

Background: Cotton is more resistant to salt and drought stresses as compared to other field crops, which makes itself as a pioneer industrial crop in saline-alkali lands. However, abiotic stresses still negatively affect its growth and development significantly. It is therefore important to breed salt tolerance varieties which can help accelerate the improvement of cotton production. The development of molecular markers linked to causal genes has provided an effective and efficient approach for improving salt tolerance. Results: In this study, a genome-wide association study (GWAS) of salt tolerance related traits at seedling stage was performed based on two years of phenotype identification for 217 representative upland cotton cultivars by genotyping-by-sequencing (GBS) platform. A total of 51,060 single nucleotide polymorphisms (SNPs) unevenly distributed among 26 chromosomes were screened across the cotton cultivars, and 25 associations with 27 SNPs scattered over 12 chromosomes were detected significantly (-log 10 p >4) associated with three salt tolerance related traits in 2016 and 2017. Among these, the associations on chromosome A13 and D08 for relative plant height (RPH), A07 for relative shoot fresh matter weight (RSFW), A08 and A13 for relative shoot dry matter weight (RSDW) were expressed in both environments, indicating that they were likely to be stable quantitative trait loci (QTLs). A total of 12 salt-induced candidate genes were identified differentially expressed by the combination of GWAS and transcriptome analysis. Three promising genes were selected for preliminary function verification of salt tolerance. The increase of GH_A13G0171-silenced plants in salt related traits under salt stress indicated its negative function in regulating the salt stress response. Conclusions: These results provided important genetic variations and candidate genes for accelerating the improvement of salt tolerance in cotton.

Background/AimscircRNA plays a key regulatory role in various human tumors. This study was carried out to investigate the molecular mechanism of circBIRC6 in the regulation of choroidal melanoma cisplatin (DDP) resistance. MethodsThe expression of circBIRC6 in choroidal melanoma tissues and cells (MUM-2B, MUM-2B / DDP) was detected by RT-qPCR. The function of circBIRC6 in DDP resistance of choroidal melanoma was analyzed by functional loss and overexpression experiments. DDP inhibition rate was detected by MTT method. Western blot was used to analysis the protein levels of P-gp, MRP1 and ERK. The relationship between circBIRC6, miR-503-3p and ERK was analyzed by CircRIP and luciferase reporter vector assay.ResultcircBIRC6 was up-regulated in choroidal melanoma, and it was significantly raised in choroidal melanoma tissues and cells that are resistant to DDP. CircBIRC6 regulated DDP resistance of choroidal melanoma cells by binding to miR-503-3p. ERK was directly targeted by miR-503-3p, and ERK inhibited miR-503-3p-induced DDP resistance. Finally, the expression of circBIRC6 was positively correlated with ERK, and it was verified that circBIRC6 regulated ERK by targeting miR-503-3p.ConclusionCircBIRC6 regulated the expression of ERK choroidal melanoma cells and DDP resistance via miR-503-3p. These results suggested that the knockout of circBIRC6 may provide an effective treatment strategy for choroidal melanoma.

Published: October 2020

Background: Alcohol consumption is associated with haemostasis and so may influence cardiovascular conditions. It is unknown whether the association of alcohol with total and g’ fibrinogen concentrations, as well as clot structure, are modulated by fibrinogen and factor (F)XIII single nucleotide polymorphisms (SNPs).Methods: Total fibrinogen, g’ fibrinogen and clot properties of 2010 healthy Africans residing in South Africa were measured in relation to alcohol intake as well as its markers – gamma-glutamyltransferase (GGT), percentage carbohydrate deficient transferrin (%CDT), aspartate aminotransferase (AST), and alanine aminotransferase (ALT). Fourteen fibrinogen and two SNPs in the FXIII gene were genotyped to determine their influence.Results: Alcohol intake and its markers correlated negatively with fibrinogen and clot lysis time (CLT) as well as with most of the clot properties. Percentage g’ fibrinogen correlated positively with AST and negatively with alcohol intake. We then stratified for alcohol intake and found inverse associations between g’ fibrinogen and both %CDT and GGT–CDT in consumers, but the positive association with AST remained only in abstainers. Alcohol intake and its markers modulated the influence of fibrinogen SNPs on total fibrinogen concentrations and the fibrinogen SNPs as well as an FXIII SNP on clot density (all p <0.004).Conclusion/s: We show for the first time that some individuals harbour certain genotypes that, in combination with alcohol consumption, might predispose or protect them from haemostatic factors that might lead to the development of cardiovascular disease. Studies are needed to clarify the mechanisms related to the interplay between alcohol and gene variants observed here.

Published: October 2020

Recently, unmanned aerial vehicle (UAV) acts as the aerial mobile edge computing (MEC) node to help the battery-limited Internet of Things (IoT) devices relieve burdens from computation and data collection, and prolong the lifetime of operating. However, IoT devices can ONLY ask UAV for either computing or caching help, and collaborative offloading services of UAV is rarely mentioned in the literature. Moreover, IoT device has multiple mutually independent tasks, which make collaborative offloading policy design even more challenging. Therefore, we investigate a UAV-enabled MEC networks with the consideration of multiple tasks either for computing or caching. Taking the quality of experience (QoE) requirement of time-sensitive tasks into consideration, we aim to minimize the total energy consumption of IoT devices by jointly optimizing trajectory, communication and computing resource allocation at UAV, and task offloading decision at IoT devices. Since this problem has highly non-convex objective function and constraints, we first decompose the original problem into three subproblems named as trajectory optimization ($\mathbf{P_T}$), resource allocation at UAV ($\mathbf{P_R}$) and offloading decisions at IoT devices ($\mathbf{P_O}$), then propose an iterative algorithm based on block coordinate descent method to cope with them in a sequence. Numerical results demonstrate that collaborative offloading can effectively reduce IoT devices’ energy consumption while meeting different kinds of offloading services, and satisfy the QoE requirement of time-sensitive tasks at IoT devices.

Published: October 2020

Background: Protein-energy wasting (PEW) is prevalent among hemodialysis (HD) patients and is associated with poor outcomes. There are various methods for evaluating nutritional status in HD patients that each has its own advantages and disadvantages. We aimed at comparing the methods of normalized protein catabolic ratio (nPCR) and malnutrition universal screening tool (MUST) with subjective global assessment (SGA) in HD patients. Method: We examined 88 HD patients using SGA and MUST questionnaires, and also nPCR were calculated using predialysis and post-dialysis BUN, and Kt/v. Also, patients were assessed for PEW based on the Criteria of the International Society of Renal Nutrition and Metabolism. Methods’ specificity, sensitivity, and precision rates were assessed. Correlations between methods were analyzed using Pearson-correlation. Results: Based on the SGA, MUST, and nPCR methods, almost 41, 30, and 60 percent of patients had malnutrition, respectively. According to the criteria by International Society of Renal Nutrition and Metabolism, more than 90 percent of patients had PEW. SGA was positively and significantly associated with MUST (P≤0.001). Sensitivity for SGA, MUST, and nPCR methods were 100,100, 1.8 %, and their specificity were 98, 98, and 4 %, respectively and their precision rates were 99.7, 98.7, and 3%, respectively. Conclusion: From various methods of nutritional assessment (SGA, MUST, and nPCR), compared to SGA as the common method of nutrition assessment in hemodialysis patients, MUST had the nearest specificity, sensitivity, and precision rate compared to SGA and nPCR method had the lowest ones. nPCR seems to be a flawed marker of malnutrition and it should be more investigated whether MUST can be used instead of SGA or not.

Ciliogenesis proteins orchestrate vesicular trafficking pathways that regulate immune synapse (IS) assembly in the non-ciliated T cells. We hypothesized that ciliogenesis-related genes might be disease candidates for common variable immunodeficiency with impaired T-cell function (T-CVID). We identified a heterozygous, predicted pathogenic variant in the ciliogenesis protein CCDC28B present with increased frequency in a large CVID cohort. We show that CCDC28B participates in IS assembly by regulating polarized T-cell antigen receptor (TCR) recycling. This involves the CCDC28B-dependent, FAM21-mediated recruitment of the actin regulator WASH to retromer at early endosomes to promote actin polymerization. The CVID-associated CCDC28BR25W variant failed to interact with FAM21, leading to impaired synaptic TCR recycling. CVID T cells carrying the ccdc28b C211T allele displayed IS defects mapping to this pathway that were corrected by overexpression of the wild-type allele. These results identify a new disease gene in T-CVID and pinpoint CCDC28B as a new player in IS assembly.
