Abstract
Background Thalassemia is one of the most common genetic diseases and a major health threat worldwide. Accurate, efficient and scalable genetic testing methodology is much needed for its molecular diagnosis and carrier screening.Results We developed NGS4THAL, a bioinformatics analysis pipeline analyzing next generation sequencing (NGS) data to detect pathogenic variants for thalassemia and other hemoglobinopathies. NGS4THAL recovers and realigns ambiguously mapped NGS reads derived from the homologous hemoglobin gene clusters to achieve accurate detection of point mutations and small insertion/deletions (InDels). And it uses several structural variant (SV) detection tools with complementary algorithms, and an inhouse database with control data on a number of known SVs to achieve accurate detection of hemoglobin SVs. Detected variants are matched with those in HbVar, allowing recognition of known pathogenic variants, including disease modifiers. Tested on simulation data, NGS4THAL achieved high sensitivity and specificity. For targeted NGS sequencing data from samples with laboratory-confirmed pathogenic hemoglobin variants, it achieved 100% detection accuracy. Application of NGS4THAL on whole genome sequencing data from unrelated studies detected thalassemia mutation carrier rates for Hong Kong Chinese and Northern Vietnamese that were consistent with those from epidemiological studies.Conclusions NGS4THAL is a highly accurate and efficient molecular diagnosis tool for thalassemia and other hemoglobinopathies based on tailored analysis of NGS data, and is potentially scalable for carrier screening purposes.

Abstract
Refractory diabetic wounds can cause persistent inflammation and delayed healing due to hypoxia. Currently, no optimal solution is available. Exosomes of adipose stem cells (ADSCs-exo) may promote skin wound healing, however, molecular mechanisms remains mysterious. We found significantly enhanced survival and proliferation of adipose stem cells after hypoxia induction compared to normoxia. Here, we aimed to investigate if hypoxic adipose stem cells exosomes (HypADSCs-exo) participate in hypoxia adaptability and accelerate diabetic wound healing. Based on high-throughput sequencing, 215 microRNAs (miRNAs) were upregulated and 369 miRNAs downregulated in HypADSCs-exo compared to ADSCs-exo. Up-regulated miR-21-3p, miR-126-5p, miR-31-5p whereas down-regulated gene miR-99b and miR-146-a correlated with wound healing. According to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG), these miRNAs might regulate cell metabolism, differentiation and Transforming growth factor-β (TGF-β) function. Consistently, HpyADSCs-exo could promote diabetic wounds healing and inhibit inflammation through PI3K/AKT signaling pathway. Collectively, HpyADSCs-exo may potentially be applied in clinical therapy as an alternative strategy to improve wound healing.

Abstract
Genotype dependency is the most important factor in wheat genetic transformation, which further limits wheat improvement by transgenic integration and genome editing approaches. The application of regeneration related genes during in vitro culture could potentially contribute to enhancement of plant transformation efficiency. In the present study, a wheat gene TaCB1 in the WUSCHEL family was identified to dramatically increase the transformation efficiencies of many wheat varieties without genotype dependency after its over-expression. The expression of TaCB1 in wheat calli did not prohibit shoot differentiation and root development. The application of TaCB1 can lighten the requirement to wheat immature embryo for plant regeneration. Transgenic wheat plants can be clearly recognized by the visible phenotype of wide flag leaves. The promise function of TaCB1 on improving transformation efficiency was also tested in T. monococcum, triticale, rye, barley, and maize.

Abstract
Recent evidence suggests that psychedelic drugs can exert beneficial effects on anxiety, depression, and ethanol and nicotine abuse in humans. However, their hallucinogenic side-effects often preclude their clinical use. Lysergic acid diethylamide (LSD) is a prototypical hallucinogen and its psychedelic actions are exerted through the 5-HT2A serotonin receptor (5-HT2AR). 5-HT2AR activation stimulates Gq- and β-arrestin- (βArr) mediated signaling. To separate these signaling modalities, we have used βArr1 and βArr2 mice. We find that LSD stimulates motor activities to similar extents in WT and βArr1-KO mice, with non-significant effects in βArr2-KOs. LSD robustly stimulates many surrogates of psychedelic drug actions including head twitches, grooming, retrograde walking, and nose-poking in WT and βArr1-KO animals. By contrast, LSD slightly stimulates head twitches in βArr2-KO mice, without effects on other surrogates. The 5-HT2AR antagonist MDL100907 (MDL) blocks these LSD effects. LSD also disrupts prepulse inhibition (PPI) in WT and βArr1-KOs; PPI is unaffected in βArr2-KOs. MDL restores PPI in WT mice, but this antagonist is without effect and haloperidol is required in βArr1-KOs. Collectively, these results reveal that LSD’s psychedelic drug-like actions appear to require βArr2.
Oral health-related quality of life among a group of patients with substance use disorders in rehabilitation treatment: a cross-sectional study
Authors: Amiri Saeed , Shekarchizadeh Hajar 
Published: May 2021

Abstract
Background
Little is known about the effect of illicit drugs on oral health-related quality of life. Our aim was to investigate oral health-related quality among patients with substance use disorder, and its association with dental caries experience and drug use profile.
Methods
Applying a stratified cluster random sampling method, we conducted a cross-sectional study on 267 in-treatment patients with substance use disorder in Isfahan, Iran in 2016. Self-administered questionnaires requested participants’ demographics and drug use profile. A trained dental student carried out personal interviews utilizing Oral Impact on Daily Performance (OIDP) instrument. Clinical examinations were conducted to record dental caries experience. T-test, ANOVA, pearson and spearman correlation coefficient, and linear regression model served for statistical analysis (p < 0.05).
Results
A great majority of the participants reported past use of opium (85%) followed by heroin (42.7%) and amphetamines (20.2%). The most common routes of drug administration were combined routes (44.6%) followed by smoking (36.7%). The mean score of OIDP was 22.4 ± 8.6. As high as 74.1% of the participants reported at least one OIDP impact. The most prevalent OIDP impact was “difficulty eating” (64.8%). The most prevalent cause of the impacts were “dental decay” and “tooth loss”. No significant association revealed between OIDP and patients’ demographics and drug use profile (p > 0.05). Participants with higher caries experience, reported greater OIDP (p < 0.05).
Conclusions
There is an oral impact on the daily performance of patients with substance use disorder. Patients with higher caries experience reported greater OIDP. Thus, in addition to normative assessment of oral health, clinicians should consider the patients' self-reported oral problems, and the social and mental aspects of oral conditions.

Published: May 2021

Abstract
Background: Obesity, metabolic disease and some psychiatric conditions are associated with changes to relative abundance of bacterial species and specific genes in the fecal microbiome. Little is known about the impact of pharmacologically induced weight loss on distinct gut microbiome species and their respective gene programs in obese individuals. Results: Using shotgun metagenomics, the composition of the microbiome was obtained for two cohorts of obese female Wistar rats (n=10-12, total of 82) maintained on a high fat diet before and after a 42-day treatment with a panel of four investigatory or approved anti-obesity drugs (tacrolimus/FK506, bupropion, naltrexone and sibutramine), alone or in combination. We found that sibutramine treatment induced consistent weight loss through reducing food intake. Weight loss in sibutramine-treated rats was associated with changes to the gut microbiome that included increased beta-diversity, increased Bacteroides/Firmicutes ratio and increased relative abundance of multiple Bacteroides species. In addition, the relative abundance of multiple genes was found to be differentially abundant, including significant reductions in components of flagellum and genes involved in flagellum assembly. Conclusions: This study provides a large resource comprising complete shotgun metagenomics datasets of the fecal microbiome coupled with weight change and food intake at day 3, day 15 and day 42 from 82 obese rats treated with a range of compounds used for weight loss, which are available to the community for detailed analysis. Furthermore, by conducting a detailed analysis of the microbiome associated with sibutramine-induced weight loss, we have identified multiple weight-loss associated microbial taxa and pathways. These include a reduction in components of flagellum and the flagellum assembly pathway that points to a potential role of sibutramine-induced weight-loss on regulating bacterially driven anti-inflammatory responses.

Published: May 2021

Abstract
Since China’s reform and opening up, foreign language teaching(hereafter: FLT) in China has achieved rapid development under the guidance of foreign language teaching theories at home and abroad. However, problems such as ‘time-consuming and inefficient foreign language learning’ and ‘dumb foreign languages’ in FLT in China have not been fundamentally solved. Based on Whitehead’s process philosophy, this research aims to put forward feasible solutions to the existing problems in FLT in China in order that the level of FLT in China can be promoted by discussing the purpose, contents, processes and stages of FLT, the relationship between teachers and students in FLT and FLT evaluation system.

Abstract
This paper explores the relationship among sperm DNA integrity, routine semen parameters and in vitro fertilization (IVF) clinical outcome. It applies sperm chromatin dispersion (SCD) test to conduct sperm DNA fragmentation index (DFI) towards the semen samples of 60 male patients who undergoing assisted reproduction techniques (ART) treatments including intrauterine insemination (IUI), in vitro fertilization (IVF), and intracytoplasmic sperm injection (ICSI) treatment in human assisted reproductive medical technology of our hospital. According to the test results, semen samples are divided into group A (DFI≤10%), group B (10%<DFI<30%) and group C (DFI≥30%) to compare semen routine main parameters in each group as well as fertility rate, cleavage rate and high-quality embryonic rate. There is a negative correlation among DFI and sperm activate rate, progressive motility(PR) rate as well as non-progressive motility(NP) rate. The difference of the sperm activate rate, progressive motility rate and non-progressive motility rate in three groups are statistically significant (P<0.05), and there is no statistically significant difference in sperm concentration (P>0.05). The fertility rate, cleavage rate and high-quality embryonic rate in each group have no statistical significance (P>0.05). Sperm DNA integrity have some connection with routine semen parameters, thus, it could play a guiding role for the analysis of semen routine diagnosis. DFI has little influence on the assisted reproductive technology IVF clinical outcome, which requires follow-up tracking clinical outcome and a large number of samples for validation.

Abstract
Introduction: Insulin resistance (IR) at the time of kidney transplant (KT) is the most significant risk factor for the development of post-transplant diabetes mellitus (PTDM) and is a strong predictor of cardiovascular morbidity and mortality in patients after KT. It is possible to improve long-term survival of grafts and patients by influencing just modifiable risk factors, including obesity and the associated IR. The aim of this work is to determine the effect of regular physical activity and lifestyle changes on IR and other risk factors for PTDM in patients after KT.Material and methods: The primary goal was to complete at least 150 minutes of moderate intensity physical exertion per week. Study group (n = 22) performed an aerobic or combined (aerobic + anaerobic) type of sports activity. Monitoring was provided by a sports tracker (Xiaomi Mi Band 4 compatible with Mi Fit mobile application). Control group was consisted of 22 stable patients after KT. Patients in both groups have the same immunosuppressive protocol. The duration of follow-up was 6 months.Results: There were significantly lower waist circumference (P = 0.0437, P = 0.0372), better graft function (P = 0.0036, P = 0.0137), lower value of fasting blood glucose (P = 0.0016, P = 0.0003), C-peptide (P = 0.0447, P = 0014) in the 3rd and 6th month of monitoring and lower low-density lipoprotein at 6 months (P = 0.0444) in the observed group compared to the control group. IR was statistically significantly lower at 6 months (P = 0.0202) and fasting blood glucose at 3 and 6 months (P = 0.0227) in the observed group. In the monitored group, the subgroup performing intensive training achieved a significant additional effect on the reduction of waist circumference (P = 0.0173). Conclusion: In our study, we confirmed a significant effect of regular physical activity in preventing the development of IR and impaired fasting glucose in patients after KT. It is necessary to perform at least 150 minutes of medium-intensity aerobic or combined sport effort per week to achieve this goal.

Abstract
Background: Biosurfactants, being environment friendly, highly biodegradable, less toxic and stable compounds have applications in several environmental and industrial sectors that includes cosmetics, biomedical, bioremediation, and agriculture. Growing concern about eco-friendly compounds leads to replacement of chemical surfactants with biological surfactants. However, use of biosurfactant limits due to high production cost. Surfactin, a class of lipopeptide, considered as powerful biosurfactants having wide applications in therapeutics and environmental field. This study aims to investigate production and characterization of surfactin by Bacillus subtilis SNW3 and evaluating their potential application in seed germination and plant growth. Results: In present study, Bacillus subtilis SNW3 was previously isolated from Chakwal Pakistan and used for biosurfactant production. Optimized media for biosurfactant production was at (6% w/v) white beans powder in combination with (1.5% w/v) waste frying oil and (0.1% w/v) urea that shows surface tension reduction (28.8 mN/m), oil displacement assay (4.9 cm) and emulsification index (69.8 %). Environmental growth parameters like temperature (30 °C), inoculum size (1%), pH (6) and agitation (150 rpm) exhibit important role towards enhanced biosurfactant yield. Furthermore, surfactin obtained was found to be most stable at (5-7) pH, (8%) NaCl and (100 °C) temperature. Biosurfactant obtained was of lipopeptide nature called surfactin characterized by thin-layer chromatography (TLC) and fourier-transform infrared spectroscopy (FTIR). The surfactin obtained, used in a concentration of (0.7 g/100 mL) helps in seed germination and significantly enhanced growth of Solanum lycopersicum (tomato), Pisum sativum (pea), Capsicum annuum (peppers) and Lactuca sativa (lettuce).Conclusions: Bacillus subtilis SNW3 produces surfactin with more stability, that makes it useful for processing of food and in agriculture. The use of white beans powder and waste frying oil as sole source of carbon and energy makes the biosurfactant production more profitable, and environment friendly procedure by utilizing food processing by-products and wastes as substrate. Results obtained provide understanding about surfactin use for seed development and plant growth.

Abstract
Background: The outbreak of the Coronavirus Disease-2019 (COVID-19) has threatened the public health of the world, and may eventually lead to acute respiratory impoverishment syndrome (ARDS). ARDS is a clinical syndrome caused by intrapulmonary or extrapulmonary reasons, which has complex pathogenesis and high mortality rate, it’s also one of the important factors in death from the 2019 novel coronavirus (2019-nCoV) epidemic. It has been reported that traditional Chinese medicine (TCM) can exert a good effect in the process of treatment. The present study aimed to observe the protective effects of TCM formula Qingfei Paidu Decoction (QFPD) on ARDS rats and explore the pharmacodynamic mechanism of the compound. Methods: 24 male rats were randomly divided into 4 groups (n=6), blank control group, model group, QFPD group (18.6g·kg-1·d-1) and dexamethasone group (2mg·kg-1·d-1). Blank control group rats were given saline, whereas other groups were injected with oleic acid (OA) and lipopolysaccharide (LPS) successively to establish ARDS model, and observed the behavioral performance of rats after model building. The morphological changes of lung tissue under optical microscope were observed; rat lung index (LI) and lung permeability index (LPI) were measured; blood PH, partial arterial oxygen pressure (PaO2, mmHg), partial arterial carbon dioxide pressure (PaCO2, mmHg), arterial oxygen saturation (SaO2) were measured by blood gas analyzer; the levels of tumor necrosis factor-α (TNF-α), interleukin (IL-1β, IL-6, IL-8, IL-10), thromboxane B2 (TXB2), 6-keto-prostaglandin F1α (6-keto-PGF1α), kerbs von lungren 6 antigen (KL-6), C-reactive protein (CRP), and the expression of superoxide dismutase (SOD) were measured via test kit.Results: Compared with the model group, the two treatment groups could improve the respiratory and lung injury in rats, and could restore the expression levels of thromboxane, various cytokines and protein to varying degrees.Conclusions: QFPD and dexamethasone have protective effects on ARDS rats induced by jointly injecting OA and LPS, and QFPD has the better effect in between. These may be related to reducing the expression levels of IL-1β, IL-6, IL-8, TNF-α, CRP, TXB2, KL-6, and increasing the contents of IL-10, 6Keto-PGF1a and SOD vitality in the body.

Authors: N Geetha , K Mahesh 
Published: May 2021

Abstract
At present days, exponential growth in the transmission of multimedia data takes place due to a significant rise in network bandwidth and video image compression technologies. However, the transmission of videos over wireless channels often brings an unseen risk that sensitive video details might be corrupted and distributed in an illegal way. So, the security of video transmission has become a hot research topic. Several encryption models have been presented in the literature, yet, it is believed that the performance of encryption process can be further improved. In this perspective, an efficient novel video encryption technique is presented using an enhanced variant of Fully Homomorphic Encryption (FHE) model called as EFHE model. By the hybridization of Ducas and Micciancio (DM) with the FHE model presented by Gentry, Sahai, and Waters (GSW), matrix operations vector additions are properly employed in the proposed EFHE model. In addition, a new key generation scheme to increase the fastness of the encryption process. The EFHE model is designed and placed on a cloud environment which leads to reduced cloud user’s communication and computation complexity. It is ensured that the presented EFHE model is highly efficient and secure over the compared methods.

Abstract
Background: In recent years, qualitative and quantitative analysis of LncRNA has been reported as a potential method for early diagnosis of bladder cancer, but the results from each research are insufficient and not completely consistent. This meta-analysis aims to evaluate the diagnostic value of LncRNA for BC.Methods: We conducted a diagnostic meta-analysis and the diagnostic significance of LncRNA in blood, urine and tumor tissues was discussed. We searched the PUBMED, EMABASE, and Cochrane Library until June 2020. The current meta-analysis was performed using Review Manager 5.2, Stata 16.0 and Meta-Disc 1.4 software. Results: A total of 18 researches involving early and/or advanced bladder cancer were finally included. The overall diagnostic accuracy was measured as follows: pooled sensitivity and specificity were 0.72 (95%CI:0.70, 0.73) and 0.76 (95%CI: 0.75, 0.78). Pooled positive likelihood ratio and negative likelihood ratio were 3.09 (95%CI: 2.66, 3.58) and 0.37 (95%CI: 0.33, 0.42). Combined diagnostic odds ratio was 9.43 (95%CI: 7.30, 12.20). A high diagnostic accuracy was demonstrated by the summary receiver operating characteristic curve, with area under the curve of 0.82 (95%CI: 0.78, 0.85). UCA1 and H19 had the best diagnostic effect, their diagnostic sensitivity and specificity were 80%, 79% and 79%, 73% respectively, the combined diagnostic odds ratio was 16.85 and 12.67 respectively.Conclusions: This meta-analysis suggests that LncRNA have great potential in the diagnosis of bladder cancer, UCA1 and H19 had the best diagnostic effect. LncRNA panel is the future development direction in the diagnosis of bladder cancer. However, larger sample researches are needed to further confirm our conclusion.
