Abstract
Background: G-protein subunit beta 1 like (GNB1L) can encode a G-protein beta-subunit-like polypeptide, the chicken GNB1L gene is up-regulated in the breast muscle of high-feed efficiency chickens, and its expression is 1.52-fold that of low-feed efficiency chickens. However, there are no reports describing the effects of GNB1L gene Indel on the chicken carcass and growth traits. Results: This study identified a 31-bp Indel in 5' UTR of the GNB1L gene and elucidated the effect of this gene mutation on the carcass and growth traits in chickens. The results showed that the 31-bp Indel was highly significant associations with body weight at 8 different stages, and also significantly correlated with daily gain of 0 to 4 weeks and 4 to 8 weeks. Similarly, the mutation was significantly associated with small intestine length, breast width, breast deep and breast muscle weight in carcass traits. Moreover, DD and ID are inferior genotypes for the growth and carcass traits of chickens. Conclusions: In a word, these results show that the 31-bp Indel of GNB1L gene is significantly affected chicken body weight and carcass traits, and can serve as a candidate molecular marker for chicken genetics and breeding programs.

Abstract
Background: This study aimed to investigate the therapeutic effect of umbilical cord mesenchymal stem cells (UCMSCs) on HBV-related liver failure and liver cirrhosis and to compare the different efficacies of UCMSCs after different treatment courses. Methods: This was an observational study that retrospectively considered a three-year period during which 513 patients who received stem cell infusion met the criteria of hepatic failure and liver cirrhosis were identified from databases of the Third Affiliated Hospital of Sun Yat-sen University. Eligible patients were categorized into the liver failure group and liver cirrhosis group. The two groups were divided into different subgroups according to the times of stem cell therapy. In the liver failure group, group A received more than 4 weeks and group B received less than 4 weeks. In the liver cirrhosis group, patients who received more than 4 weeks of stem cell therapy belonged to group C, and group D received less than 4 weeks. The patients were followed up for 24 weeks. The demographics, clinical characteristics, biochemical factors, and MELD scores were recorded and compared among different groups. Results: A total of 64 patients met the criteria of liver failure, and 59 patients met the criteria of liver cirrhosis. After UCMSC treatments, the levels of ALT, AST, and TBIL at all postbaseline time points were significantly lower than those at baseline in the liver failure group and liver cirrhosis group; the PTA and MELD scores only gradually improved in the liver failure group. Four weeks after UCMSC treatment, patients with prolonged treatment with UCMSCs had higher TBIL decline levels than patients who terminated treatment with UCMSCs. After more than 4 weeks of UCMSC treatment, there was no statistically significant difference in the levels of change for ALT, AST, TBIL, PTA value and the MELD score between patients with liver failure with prolonged treatment with UCMSCs and patients with liver cirrhosis with prolonged treatment with UCMSCs at all observation weeks. However, the median decline and cumulative decline in the TBIL level of patients with liver failure with a standard 4-week treatment course were higher than those of patients with liver cirrhosis with a standard 4-week treatment course. Conclusion: Peripheral infusion of UCMSCs showed good therapeutic effects for HBV-related liver failure and liver cirrhosis. Prolonging the treatment course can increase the curative effect of UCMSCs for end-stage liver disease, especially for patients with cirrhosis.

Abstract
Background
Roots are critical for water and nutrient acquisition, environmental adaptation and yield formation.
Results
Here, 196 accessions from Yellow and Huai Winter Wheat Region (YHW) of China were collected for investigating the performance of six root traits under three cultivation patterns—Indoor Hydroponic Culture (IHC), Outdoor Hydroponic Culture (OHC) and Outdoor Pot Culture (OPC) at different growth stages—for three consecutive years. In the same growth period, OPC root traits always varied greatly, followed by OHC and IHC. The correlation coefficients between IHC and OPC at stooling stage (SS) were lower (0.016 ~ 0.278) than those between OHC and OPC (0.29 ~ 0.378). Root traits were negatively correlated grain yield (GY), the canonical correlation coefficient between root traits and yield was the highest (0.232) at SS. Genome-wide association study (GWAS) was furtherly conducted by a wheat 660K SNP array. It was revealed that 1105 SNP loci were significantly associated with root traits. A co-localized chromosomal segment regulating total root length (TRL) was detected on chromosome 4A, spanning from 737.85 to 742.00 Mb, under different cultivation patterns at stooling stage. Another co-localization region regulating total root area (TRA) was detected on chromosome 5A, an approximately 6.17 ~ 18.76 Mb region at SS, wintering stage (WT) and jointing stage (JS) under OPC. LD analysis and blast comparison revealed 27 and 31 genes related to root development were found from these two segments, respectively. Among them, TraesCS4A02G493900, TraesCS4A02G494200, TraesCS5A02G021700, TraesCS5A02G021800 and TraesCS5A02G011600 were predicted to be highly expressed in root.
Conclusion
This work could deepen our understanding of the molecular mechanisms of root development under different cultivation patterns in common wheat.
Transcriptome and metabolite profiling reveals the effects of Funneliformis mosseae on the roots of continuously cropped soybeans
Authors: Lu Cheng-Cheng , Guo Na , Yang Chao , Sun Hai-Bing , Cai Baiyan 
Published: June 2020

Abstract
Background
Arbuscular mycorrhizal fungi are the most widely distributed mycorrhizal fungi, which can form mycorrhizal symbionts with plant roots and enhance plant stress resistance by regulating host metabolic activities. In this paper, the RNA sequencing and ultra-performance liquid chromatography (UPLC) coupled with tandem mass spectrometry (MS/MS) technologies were used to study the transcriptome and metabolite profiles of the roots of continuously cropped soybeans that were infected with F. mosseae and F. oxysporum. The objective was to explore the effects of F. mosseae treatment on soybean root rot infected with F. oxysporum.
Results
According to the transcriptome profiles, 24285 differentially expressed genes (DEGs) were identified, and the expression of genes encoding phenylalanine ammonia lyase (PAL), trans-cinnamate monooxygenase (CYP73A), cinnamyl-CoA reductase (CCR), chalcone isomerase (CHI) and coffee-coenzyme o-methyltransferase were upregulated after being infected with F. oxysporum; these changes were key to the induction of the soybean’s defence response. The metabolite results showed that daidzein and 7,4-dihydroxy, 6-methoxy isoflavone (glycine), which are involved in the isoflavone metabolic pathway, were upregulated after the roots were inoculated with F. mosseae. In addition, a substantial alteration in the abundance of amino acids, phenolic and terpene metabolites all led to the synthesis of defence compounds. An integrated analysis of the metabolic and transcriptomic data revealed that substantial alterations in the abundance of most of the intermediate metabolites and enzymes changed substantially under pathogen infection. These changes included the isoflavonoid biosynthesis pathway, which suggests that isoflavonoid biosynthesis plays an important role in the soybean root response.
Conclusion
The results showed that F. mosseae could alleviate the root rot caused by continuous cropping. The increased activity of some disease-resistant genes and disease-resistant metabolites may partly account for the ability of the plants to resist diseases. This study provides new insights into the molecular mechanism by which AMF alleviates soybean root rot, which is important in agriculture.

Published: June 2020

Abstract
In the context of this research work, we study the so-called problem of full snapshot reconstruction in hybrid antenna array structures that are utilized in mmWave communication systems. It enables the recovery of the snapshots that would have been obtained if a conventional (non-hybrid) Uniform Linear Antenna (ULA) array was employed. The problem is considered at the receiver side where the hybrid architecture exploits in a novel way antenna elements of a uniform linear array. To this end, the recommended scheme is properly designed so as to be applicable to overlapping and non-overlapping architectures. Moreover, the full snapshot recoverability is addressed for two cases, namely, for time-varying and constant signal sources. Simulation results are also presented to illustrate the consistency between the theoretically predicted behaviors and the simulated results, and the performance of the proposed scheme in terms Angle-of-Arrival (AoA) estimation, when compared to the conventional MUSIC algorithm and a recently proposed hybrid version of MUSIC (H-MUSIC).

Published: June 2020

Abstract
Background

The coronavirus disease 2019 (COVID-19) pneumonia, outbreak in Wuhan, China, has led to a global pandemic. The high mortality of COVID-19 patients makes it significant to evaluate possible disease progression. This study was designed to explore the prognostic value of Controlling Nutritional Status (CONUT) score in patients with COVID-19.
Methods

Patients diagnosed with COVID-19 of a single center in Wuhan, China from January 2020 to February 2020 were enrolled in this study. Logistic regression analysis was performed to find independent risk factor of mortality. Receiver operating characteristics (ROC) curve was drawn to evaluate the prognostic value of CONUT score.
Results

Among 442 included patients, there were 79 non-survivors with mortality of 17.9%. Compared with survivors, the median age (p < 0.001) and male ratio (p = 0.042) were higher in non-survivors. Non-survivors had higher incidence of comorbidities including hypertension (p < 0.001), chronic lung disease (p = 0.001) and cardiovascular disease (p = 0.005). Complications such as respiratory failure(p < 0.001), acute kidney injury (AKI) (p < 0.001) occurred more frequently in non-survivors. Multivariate logistic regression analysis showed that CONUT (p = 0.002), lactate dehydrogenase (LDH) (p < 0.001), C-reactive protein (CRP) (p = 0.020) were risk factor of mortality in COVID-19 patients. Area under the ROC curve (AUC) of CONUT and Nutrition risk screening 2002 (NRS2002) score were 0.813 and 0.795, respectively. Comprised of CONUT, LDH, CRP, the constructed prognostic model had higher AUC of 0.923 (Z = 3.5210, p < 0.001).
Conclusion

CONUT is an independent risk factor of mortality in COVID-19 patients. Evaluating CONUT is beneficial for clinicians to predict the progression of COVID-19 patients and strengthen monitoring and management to improve prognosis.

Published: June 2020

Abstract
Background:Actin is an essential cellular protein that assembles into microfilaments and regulates numerous processes such as cell migration, maintenance of cell shape, and material transport. In this study, we explored the effect of actin polymerization state on the osteogenic differentiation of human adipose-derived stem cells (hASCs). Methods:The hASCs were treated with different concentrations (0, 1, 5, 10, 20, and 50 nM)of jasplakinolide (JAS), a reagent that directly polymerizes F-actin.The effects ofthe actin polymerization state on cell proliferation, apoptosis, migration, and the maturity of focal adhesion-related proteins were assessed. In addition, western blotting and alizarin red staining assays were performed to assess osteogenic differentiation. Results: These results revealed that cell proliferation and migration in the JAS (0, 1, 5, 10, and 20 nM) groupswashigher than that inthe control group andthe JAS (50 nM) group.The protein expressionof focal adhesion kinase, vinculin, paxillin, and talinwere highest in the JAS (20 nM) group, whilezyxin expression was highestinthe JAS (50 nM) group.Western blottingshowed thatosteogenic differentiation in theJAS (0, 1, 5, 10, 20, and 50 nM) groupswas enhanced compared with that in thecontrol group, and was strongest inthe JAS (50 nM) group.Conclusions: Our data suggest thatthe actinpolymerization state may promote the osteogenic differentiation of hASCs by regulating the protein expression of focal adhesion-associated proteins in a concentration-dependent manner. Our findings provide valuable information for exploring the mechanism of osteogenic differentiationin hASCs.

Authors: Zhuang Wenyuan , Liu Ning , Guo Hongqian , Gan Weidong , Zhang Chunni 
Published: June 2020

Abstract
Background
Xp11.2 translocation renal cell carcinoma (tRCC) is recently recognized. As Xp11.2 tRCC involved gene translocation and fusion in X chromosome and the number of X chromosomes in female is twice of male, we wondered whether the gender difference of attack rate is consistent with the proportion of the X chromosome.
Methods
In the present paper, meta-analysis was performed to find out the difference of morbidity between male and female.
Results
9 studies with 209 cases calculated. Odds ratios (ORs) and ORs with 95% confidence intervals (CIs) were calculated for attack rate of Xp11.2 RCC with different gender. The result showed that the attack rate of female was higher than that of male with pooled OR of 2.84 (95% CI = 1.48–5.45), while the rate rises even further in adult (OR = 3.37, 95% CI = 2.19–5.18). In other types of common kidney cancer, the OR value is less than 1, which means that the incidence of female is lower than that of male.
Conclusions
The result showed that the incidence rate of female patients is much higher than that of male patients with Xp11.2 tRCC, it was reasonable to indicate that this particular incidence rate is related to the X chromosome.

Published: June 2020

Abstract
Objective: The aim of this study was to analyze the use of modified, cast splint Herbst appliances for the treatment of skeletal class II and as an alternative to surgical bite correction over a period of five years.Materials and methods: The patient cases all originate from the patients of the Department of Orthodontics at the University Medical Center of the Johannes Gutenberg University Mainz, Germany and the orthodontic practice Dres. Zöller, Kaiserslautern, Germany. Inclusion criteria were orthodontic treatment with the Herbst appliance and its modifications. The type of modification, number and frequency of the different modifications were determined on the basis of patient files, X-ray documents, photos and models. Results: Of a total of 2881 new admissions over a period of five years, 1751 patients came from the Department of Orthodontics at the University Medical Center of the Johannes Gutenberg University Mainz and 1130 from the orthodontic practice in Kaiserslautern. A total of 336 patients were treated with a Herbst appliance during the period mentioned. 14 (13 %) of the cases from the Herbst patient collective of the University Medical Center and 45 (19 %) of the cases from the orthodontic practice were classified as modifications. The following modifications could be determined in descending order: University Medical Center Mainz: Herbst for anchoring during space closure (65 %) > distalization (14 %) ≥ Bar construction as a space maintainer (14 %) > Herbst applicance for anchoring for the adjustment of impacted teeth (7 %); orthodontic practice Kaiserslautern: Herbst appliance with quadhelix in the maxilla (42 %) > distalization (27 %) > space closure (15 %) > bar construction as a space maintainer (9 %) > adjustment of impacted teeth (7 %), multiple modifications occurred at 11 %. The combination of quadhelix and Herbst appliance as well as multiple modifications have not yet been used in the University Medical Center Mainz. As an alternative to dysgnathia surgery, 23 adult patients (> 18 years) from the University Medical Center and 22 from the orthodontic practice were treated with a Herbst appliance.Conclusion: Nearly 12 % of Herbst appliances are used in everyday orthodontic practice and almost 18 % of these are used with modification(s). The high anchoring quality and force-effect geometry of the Herbst appliance is suitable for combining and treating various other treatment tasks in addition to the classical treatment task of class II therapy.

Published: June 2020

Abstract
Neuropathic pain induced by a nerve injury could lead to chronic pain. Recent studies have reported hyperactive neural activities in the nociceptive-related area of the brain as a result of chronic pain. Although cerebral activities associated with hyperalgesia and allodynia in the chronic pain model were difficult to represent with functional imaging techniques, advances in manganese (Mn)-enhanced magnetic resonance imaging (MEMRI) could facilitate the visualization of the activation of pain-specific neural responses in the cerebral cortex. In order to investigate the alleviation of pain nociception by mammalian target of rapamycin (mTOR) modulation, we observed the cerebrocortical excitability changes and compared the regional Mn 2+ enhancement after mTOR inhibitions. At day 7 after nerve injury, drugs were applied into the intracortical area, and drug (Vehicle, Torin1 and XL388) effects were compared within groups using MEMRI. In the results, signal intensities of the insular cortex (IC), primary somatosensory cortex of the hind limb region (S1HL), motor cortex 1/2 (M1/2), and anterior cingulate cortex (ACC) regions were significantly reduced after application of mTOR inhibitors (Torin1 and XL388). Furthermore, the rostral-caudal analysis of the IC indicated that the rostral region of the IC was more associated with pain perception than caudal region. Our data suggest that MEMRI could present the pain-related signal changes in the brain, and mTOR inhibition is closely correlated with pain modulation in chronic pain rats.

Abstract
In the present work, a remediation bioprocess based on the use of a native isolate of Chlorella vulgaris immobilized in an alginate matrix inside a polylactic acid (PLA) device is proposed. This microalga immobilized in alginate beads was previously shown to be useful for the reduction of several chemical and microbial contaminants present in the highly polluted water from the Matanza-Riachuelo watershed. However, these beads had a relatively short shelf life in the natural environment. To overcome this limitation, a 3D-printed PLA device was designed and tested. PLA is a biocompatible and biodegradable material suitable for biotechnological applications. We used Erlenmeyers and stirred-tank bioreactors fed with Murashige Skoog (MS) culture medium or water from the Cildáñez stream (one of the water bodies of the aforementioned watershed) to estimate the growth kinetics parameters and the bioremediation capacity of immobilized-microalgal cells as an unconfined system (UcS) or a confined system (CfS) inside PLA devices. Although alga’s growth parameters were maximum in the UcS fed with MS medium as substrate, successful bioremediation of the target water was possible using the CfS: all inorganic nitrogen forms and total phosphorus were reduced at least by 90% after 5 days of bioprocess in an agitated bioreactor, whereas aerobic mesophilic bacteria decreased by about 85%. The number of coliforms also decreased. Standardized cytotoxicity tests using Allium cepa seeds confirmed the high degree of decontamination achieved by the use of immobilized microalga confined in a 3D-printable PLA-device.

Abstract
Background:Triggering receptor expressed on myeloid cells 2 (TREM2) is expressed in the brain exclusively on microglia and genetic variants are linked to neurodegenerative diseases including Alzheimer’s disease (AD), frontotemporal dementia (FTD) and NasuHakola Disease (NHD). The Trem2 variantR47H, confers substantially elevated risk of developing late onset Alzheimer’s disease, while NHD-linkedTrem2 variants like Y38Care associated with development of early onset dementia with white matter pathology. However, it is not known how these Trem2species predispose individuals to presenile dementia.Methods:To investigate if Trem2 Y38C or loss of Trem2 alters neuronal function, we generated a novel mouse model to introduce the NHD Trem2 Y38C variant in murine Trem2 using CRISPR/Cas9 technology. Trem2Y38/Y38C and Trem2-/-mice were assessed for Trem2 expression, differentially expressed genes, synaptic protein levels and synaptic plasticity using biochemical, electrophysiological and transcriptomic approaches.Results:While mice harboring Trem2 Y38C exhibited normal expression levels of Trem2, the pathological outcomes phenocopied Trem2-/- miceat 6 months. Transcriptomic analysis revealed altered expression of neuronal and oligodendrocytes/myelin genes. We observed regional decreases in synaptic protein levels, with the most affected synapses in the hippocampus. These alterations were associated with reduced synaptic plasticity. Conclusion:Our findings provide in vivo evidence that Trem2 Y38C disrupts normal TREM2 functions. Trem2Y38C/Y38Cand Trem2-/- mice demonstrated altered gene expression, changes in microglia morphology, loss of synaptic proteins and reduced hippocampal synaptic plasticity at 6 months in absence of any pathological triggers like tau or amyloid. This suggests TREM2 impacts neuronal functions and providesmolecular insights on the predisposition of individuals with TREM2 variants resulting in presenile dementia.
