Effect of cold atmospheric plasma on changing of biomolecular structures involved in apoptosis pathways of melanoma cancer.

BACKGROUND: Cold atmospheric plasma (CAP), is a technology based on non-thermal ionized gas that is used for cancer therapy in research. We evaluated the effect of CAP on malignant melanoma cancer cell line (B16) in comparison with normal cells (L929). METHODS: The effect of CAP on the cytotoxicity of B16 and L929 cell lines was assayed by the MTT method and inverted microscopy. The induction of apoptosis in cells was evaluated using a fluorescence microscope. FTIR monitored the CAP effect in biomacromolecules changes in these cell lines. QPCR assayed gene expression of BAX, BCL-2, and Caspase-3 (CASP-3). RESULTS: The results of the MTT test showed CAP has a cytotoxic effect on the B16 cancer cell line more than L929 normal cells (p < 0.0001). The results of invert and fluorescence microscopy showed CAP-induced apoptotic morphology on cancerous cells. FTIR spectroscopy indicated CAP changes biomacromolecules structure. Evaluation of gene expression showed CAP increased BAX and CASP-3 gene expression. Also, it decreased BCL-2 gene expression. CONCLUSIONS: Taken together, CAP may change biomacromolecule structures involved in apoptosis pathways, decrease proliferation and induce apoptosis in cancer cells.

Organochlorine knockdown-resistance (kdr) association in housefly (Musca domestica): A systematic review and meta-analysis.

Introduction: Although house flies (Musca domestica) do not directly cause disease in humans, they transmit pathogens to them, which provide the basis for many diseases. The main way to deal with this insect is to use insecticides. Due to the resistance from insecticides, the fight against house flies has been hampered. This study aimed to determine the prevalence of knockdown resistance against organochlorine insecticides in house flies worldwide. Methods: This study was conducted via a systematic review and meta-analysis to investigate the prevalence of knockdown resistance against organochlorine insecticides in house flies. Accordingly, by searching the databases of Web of Science, PubMed, Scopus, Proquest, Bioone, and Embase, all published articles were extracted, and reviewed until the end of May 2022. Statistical data analysis was performed using the random-effects model in the meta-analysis, meta-regression, and I2 index. Results: Nine studies entered the meta-analysis process. Based on this, the prevalence of knockdown resistance against organochlorine insecticide in house flies was estimated to be 49.1%. Meta-regression showed that the prevalence of knockdown resistance increased with increasing years of study but decreased with increasing sample size. Conclusion: According to the findings, about 50% of house flies have knockdown resistance against organochlorine insecticide. As a result, it is necessary to adopt effective and combined methods to combat this insect to control it and prevent the transmission of diseases caused by it.

Evaluation of resistance of human head lice to pyrethroid insecticides: A meta-analysis study.

Introduction: Pediculosis is one of the most common annoying infections caused by parasitic lice in humans. Pyrethroids are one of the main insecticides used to treat this infection. But recently, due to the Resistance of lice to this group of insecticides, its insecticidal effects have been affected. The present study was conducted through a meta-analysis to investigate the prevalence of pyrethroid resistance against these insecticides worldwide. Methods: This study was conducted as a meta-analysis of the prevalence of treatment resistance in human head lice against pyrethroid insecticides worldwide. Based on this, all articles published without a time limit until the end of June 2022 in PubMed/MEDLINE, Web of Science (ISI), Scopus, and Google Scholar databases were extracted and using random-effects meta-analysis model statistical methods in the meta-analysis, Cochrane, Index I2, and funnel plot were analyzed by STATA software. Results: Twenty studies were included in the meta-analysis process. According to this, the prevalence of pyrethroid resistance insecticides in human head lice was estimated at 59% (CI95%: 50%-68%). Among pyrethroid insecticides, the highest prevalence of pyrethroid resistance against permethrin insecticide was 65%. Regarding the prevalence of Resistance by year, the prevalence before 2004 was estimated at 33%, but after 2015, this rate reached 82%. Also, the majority of pyrethroid resistance was estimated at 68% using genetic diagnosis methods and 43% using clinical diagnosis methods. Conclusion: More than half of human head lice pyrethroid resistance insecticides. Based on this, it is recommended that before using this treatment method to treat human head lice Infestation, it should investigate the prevalence of pyrethroid resistance in that area, and if the majority of Resistance is high, alternative or combined treatment methods should be used.

Designing novel peptides for detecting the Omicron variant, specifying SARS-CoV-2, and simultaneously screening coronavirus infections.

In this study in silico a candidate diagnostic peptide-based tool was designed in four stages including diagnosis of coronavirus diseases, simultaneously identifying of COVID-19 and SARS from other members of this family, specific identification of SARS-CoV2, and diagnosis of COVID-19 Omicron. Designed candidate peptides consist of four immunodominant peptides from the proteins of the SARS-CoV-2 spike (S) and membrane (M). The tertiary structure of each peptide was predicted. The stimulation ability of the humoral immunity for each peptide was evaluated. Finally, in silico cloning was performed to develop an expression strategy for each peptide. These four peptides have suitable immunogenicity, appropriate construct, and the ability to be expressed in E.coli. These results must be experimentally validated in vitro and in vivo to ensure the immunogenicity of the kit.Communicated by Ramaswamy H. Sarma.

The Effect of Interactive Virtual Psycho-Educational Interventions via Social Networks on Self-Efficacy and Anxiety Among Patients Infected with COVID-19 and Living in Home Quarantine: A Randomized Control Trial.

Background: Psycho-educational interventions might play a crucial role in the management of diseases. This study was conducted to determine the effect of psycho-educational interventions via social networks on self-efficacy and anxiety among Coronavirus Disease 2019 (COVID-19) patients in home quarantine. Materials and Methods: This randomized clinical trial was conducted on 72 COVID-19 patients, in Shiraz, Iran, in 2020. The patients were randomly assigned to an intervention and control group. Patients in the intervention group underwent psycho-educational interventions daily for 14 days. The data were collected using the Strategies Used by People to Promote Health (SUPPH) questionnaire and the State-Trait Anxiety Inventory (STAI) before and 2 weeks after the intervention. Results: After the intervention, the mean score of SUPPH was mean = 120.75 (16.56) and mean(SD) 111.27 (14.40) in the intervention and control groups, respectively. Moreover, after the intervention, the mean score of state and trait anxiety were 34.69 (10.75) and 38.31 (8.44) in the intervention group, and mean(SD) 45.75 (13.01) and 43.50 (8.44) in the control group, respectively. After the intervention, a difference was observed between the groups concerning the mean score of SUPPH (t70 = 2.58; p = 0.01), state anxiety (F1 = 16.52; p < 0.001), and trait anxiety (t70 = -2.49; p = 0.01). Conclusions: Considering the effectiveness of psycho-educational interventions in self-efficacy and anxiety, healthcare providers are recommended to use these interventions in COVID-19 patients.

AIM: To estimate the effect size of distance education on the readmission of patients with heart failure. DESIGN: This study was a systematic review and meta-analysis. METHOD: Both Persian and English interventional studies focused on investigating the effectiveness of any form of distance education interventions on the readmission of patients with heart failure were retrieved from the main databases: Embase, PubMed, Scopus, Web of Science, SID, and Google Scholar. Two independent teams screened the articles for eligibility. The Cochrane Risk of bias tool was implemented to evaluate the studies' quality. A random-effects model was applied to pool the effect sizes, I2 was calculated to examine heterogeneity, and Meta-regression was used to investigate the source of heterogeneity. The proposal was registered in the PROSPERO database (no. CRD42020187453). RESULTS: Articles 8836 were retrieved, and 11 articles were selected. Nine studies investigated the effect of distance education on readmission with <12-month follow-up (RR: 0.78 [95% CI 0.67-0.92]) and the I2 of 0.00%; and four studies examined the effect of distance intervention on readmission with 12-month or more follow-up (RR: 0.89 [95% CI 0.73-1.09]) and the I2 of 71.59%.

In Silico Analysis of a Candidate Multi-epitope Peptide Vaccine Against Human Brucellosis.

Brucellosis is one of the neglected endemic zoonoses in the world. Vaccination appears to be a promising health strategy to prevent it. This study used advanced computational techniques to develop a potent multi-epitope vaccine for human brucellosis. Seven epitopes from four main brucella species that infect humans were selected. They had significant potential to induce cellular and humoral responses. They showed high antigenic ability without the allergenic characteristic. In order to improve its immunogenicity, suitable adjuvants were also added to the structure of the vaccine. The physicochemical and immunological properties of the vaccine were evaluated. Then its two and three-dimensional structure was predicted. The vaccine was docked with toll-like receptor4 to assess its ability to stimulate innate immune responses. For successful expression of the vaccine protein in Escherichia coli, in silico cloning, codon optimization, and mRNA stability were evaluated. The immune simulation was performed to reveal the immune response profile of the vaccine after injection. The designed vaccine showed the high ability to induce immune response, especially cellular responses to human brucellosis. It showed the appropriate physicochemical properties, a high-quality structure, and a high potential for expression in a prokaryotic system.

The association between vitamin C dietary intake and its serum levels with anthropometric indices: A systematic review and meta-analysis.

BACKGROUND: studies showed inflammatory background of overweight and obesity. Prevalence of weight disorders has dramatically increased over the past few decades. Vitamin C is an antioxidant and may be associated with weight disorders. This study aims to systematically review the relationship between dietary and serum vitamin C levels with anthropometric indices. METHODS: A systematic search was conducted in Medline database (PubMed), Scopus, Embase, Web of Science, Cochrane library and Google Scholar up to the end of August 2021. All observational studies that assessed the relationship between dietary or circulating vitamin C levels and body mass index (BMI) and waist circumference (WC) on adults were included. The quality of included studies was assessed using the National Institute of Health quality assessment tool. RESULTS: Among 11,689 studies, 47 and 37 articles were included in the systematic review and meta-analysis, respectively. There was an inverse significant correlation between WC and serum vitamin C levels (r = -0.28, 95% CI: -0.35,-0.21, I2 = 14.2%) and between BMI and serum vitamin C levels (r = -0.17, 95% CI: -0.25, -0.09, I2 = 72.8%). Higher vitamin C consumption was significantly associated with lower BMI. There were no significant differences in serum vitamin C levels between normal-weight and overweight subjects, but serum vitamin C levels were significantly higher in obese subjects in comparison with normal-weight subjects. CONCLUSION: Results showed that both dietary and serum vitamin C levels were inversely associated with BMI and WC. More well-designed clinical trials are needed to assess the effect of vitamin C supplementation in prevention and treatment of obesity.

Combination effect of cold atmospheric plasma with green synthesized zero-valent iron nanoparticles in the treatment of melanoma cancer model.

Green synthesized zero-valent iron nanoparticles (nZVI) have high potential in cancer therapy. Cold atmospheric plasma (CAP) is also an emerging biomedical technique that has great potential to cure cancer. Therefore, the combined effect of CAP and nZVI might be promising in treatment of cancer. In this study, we evaluated the combined effect of CAP and nZVI on the metabolic activity of the surviving cells and induction of apoptosis in malignant melanoma in comparison with normal cells. Therefore, the effect of various time exposure of CAP radiation, different doses of nZVI, and the combined effect of CAP and nZVI were evaluated on the viability of malignant melanoma cells (B16-F10) and normal fibroblast cells (L929) at 24 h after treatment using MTT assay. Then, the effect of appropriate doses of each treatment on apoptosis was evaluated by fluorescence microscopy and flow cytometry with Annexin/PI staining. In addition, the expression of BAX, BCL2 and Caspase 3 (CASP3) was also assayed. The results showed although the combined effect of CAP and nZVI significantly showed cytotoxic effects and apoptotic activity on cancer cells, this treatment had no more effective compared to CAP or nZVI alone. In addition, evaluation of gene expression showed that combination therapy didn't improve expression of apoptotic genes in comparison with CAP or nZVI. In conclusion, combined treatment of CAP and nZVI does not seem to be able to improve the effect of monotherapy of CAP or nZVI. It may be due to the resistance of cancer cells to high ROS uptake or the accumulation of saturated ROS in cells, which prevents the intensification of apoptosis.

The combined effect of fish oil containing Omega-3 fatty acids and Lactobacillus plantarum on colorectal cancer.

Colorectal cancer (CRC) is one of the deadliest malignancies. Recent attempts have indicated the role of diet in the etiology of CRC. Natural dietary compounds such as probiotics and Omega-3 fatty acids that act synergistically can be beneficial in finding a tremendous solution against CRC. To date, the combined effect of fish oil containing Omega-3 fatty acids (Omega-3) and Lactobacillus plantarum (L. plantarum) on CRC has been left behind. We here evaluated the effects of co-encapsulation of Omega-3 and probiotic bacteria on CRC cell lines compared to normal cells. Omega-3 and L. plantarum bacteria were co-encapsulated in three ways, including gelatin-gum Arabic, gelatin-chitosan, and chitosan-gum Arabic complex coacervate microcapsules. After treatment of cells (Normal [L929] and colorectal [C26]) by L. plantarum, Omega-3, and microcapsules, viability and growth capacity of cell lines were measured using the MTT (3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide) assay. Isolated total RNA was used to evaluate the expression profile of BCL2-associated X protein (BAX), B-cell lymphoma 2 (BCL-2), and Caspase-3 (CASP3) genes by real-time polymerase chain reaction (PCR). Statistical analysis was performed with SPSS 25 software. A value of p < .05 was considered statistically significant. The results indicated a significant reduction in cell viability of C26 in a concentration-dependent manner in the treated cells with all treatments, except gelatin-gum Arabic microcapsules. The messenger RNA (mRNA) expression level of the BAX and CASP3 genes in C26 cells being treated with all treatments significantly increased than in untreated cells, and the expression level of the anti-apoptotic factor of the BCL-2 gene decreased in C26 cells simultaneously (p < .05). Although, the combined effect of Omega-3 and L. plantarum and microcapsulated treatments had no more effect on viability and apoptosis gene expression of cancer cells compared to Omega-3 or L. plantarum. In conclusion, combination therapy with fish oil containing Omega-3 and L. plantarum does not improve the anticancer effect of each alone.

Comparing the effects of multimedia and face-to-face pain management education on pain intensity and pain catastrophizing among patients with chronic low back pain: A randomized clinical trial.

INTRODUCTION: Previous studies into Low Back Pain (LBP) assessed the effects of physical interventions or face-to-face (FTF) education mostly in western cultures. The present study aimed to compare the effects of multimedia and FTF pain management education (PME) on pain intensity and pain catastrophizing among participants with chronic LBP. METHODS: This double-blind randomized controlled clinical trial was conducted on ninety participants with chronic LBP randomly allocated to either multimedia, FTF, or control groups. Participants in the multimedia group received PME through watching seven educational CDs at home and their counterparts in the FTF group received the same educations in seven weekly FTF educational sessions. Pain intensity (using a numerical rating scale) and pain catastrophizing (using the Pain Catastrophizing Scale) were assessed before, immediately after, and one month after the study intervention. The effects of the interventions were assessed using the repeated-measures multivariate analysis of variance (MANOVA). Effect size and minimal detectable change (MDC) were reported for both variables. The regression model used in the present study was Generalized Estimating Equations (GEE). FINDINGS: The findings of MANOVA showed the significant effects of time on pain intensity and pain catastrophizing (P<0.001). The Tukey's test showed that before and immediately after the intervention, the mean scores of pain intensity and pain catastrophizing in the FTF and PME groups were significantly different from the control group (P<0.001 and P = 0.001, respectively). MDC did not show clinically significant changes in the mean score of pain intensity and GEE revealed significant difference among the groups. CONCLUSION: The findings suggested that multimedia PME is as effective as FTF education in reducing pain intensity and pain catastrophizing among participants with LBP. Future studies into the effects of education on LBP are recommended to consider longitudinal designs, a reliable cutoff score for pain catastrophizing, and participants' physical ability.

Designing a novel multiepitope peptide vaccine against melanoma using immunoinformatics approach.

Malignant melanoma is the most aggressive and life-threaten skin cancer. Nowadays, the prevention and treatment of melanoma are challenging areas for researchers and physicians. Therefore, we implemented an in silico-based approach to design a multi-epitope peptide vaccine for melanoma. This approach consists of immunoinformatics, molecular docking, and dynamic stimulation assessments to identify potent targets. Three most immunogenic melanoma proteins; NEYSO-1, gp-100, and MART-1were considered to predict immunodominant B and T cell epitopes. The prioritized epitopes had significant potential to induce strong humoral and cellular immunity and INF-γ responses without the possibility of allergenicity. To enhance the immunogenic properties of the vaccine, we used adjuvants HBHA, the helper epitope of PADRE, and three segments of the helper epitope from TTFrC. To design the final vaccine construct, appropriate linkers are used to join immunogenicscreened-epitopes and also the adjuvants. The physicochemical and immunological properties of the vaccine were evaluated.The designed-vaccine construct was docked to TLR4 to visualize the complex affinity and then conformational dynamics simulation was used to analyze time-dependent interaction behavior. In silico cloning demonstrated that the vaccine can be efficiently expressed in E.coli. Therefore, the designed vaccine might have the ability to induce humoral and cellular immune responses against melanoma cancer antigens. This vaccine has a high-quality structure and suitable characteristics such as high stability, solubility, and a high potential for expression in a prokaryotic system. However, these results need the experimental study to ensure the immunogenicity and safety profile of the melanoma candidate vaccine construct.

Serum levels and genetic variation of IL-35 are associated with multiple sclerosis: a population-based case-control study.

This study aimed to investigate the association between serum levels and polymorphic variants of IL-35 with susceptibility, clinical features, and disease severity in multiple sclerosis (MS) patients.This case-control study recruited 186 MS patients and 195 sex- and age-matched healthy controls. Serum levels and polymorphic variants of IL-35 were determined by ELISA and restriction fragment length polymorphism (RFLP)-PCR or high resolution melting (HRM) analysis methods, respectively. In addition, by in silico analysis, we evaluated the location and function of the polymorphism.Serum levels of IL-35 were significantly lower in the patients than those of healthy controls (49.3 ± 3.7 vs. 69.5 ± 7.8, p = 0.009). EBI3 rs4740 polymorphism of IL-35 was associated with 2.2-fold increased risk of MS susceptibility (95% CI, 1.3-3.9, p = 0.005). However, there were no differences in the genotype distribution and allele frequencies of IL-35 rs568408 between the patients and controls (p > 0.05). In silico results showed that variation in IL-12A and EBI3 may affect on protein pathways of the cells and different components of the immune system such as NF-κB and INF-γ.The results show that IL-35 polymorphisms might be a genetic risk factor for the development of MS.

Combined Effect of Cold Atmospheric Plasma and Curcumin in Melanoma Cancer.

Curcumin (CUR) has interesting properties to cure cancer. Cold atmospheric plasma (CAP) is also an emerging biomedical technique that has great potential for cancer treatment. Therefore, the combined effect of CAP and CUR on inducing cytotoxicity and apoptosis of melanoma cancer cells might be promising. Here, we investigated the combined effects of CAP and CUR on cytotoxicity and apoptosis in B16-F10 melanoma cancer cells compared to L929 normal cells using MTT method, acridine orange/ethidium bromide fluorescence microscopic assay, and Annexin V/PI flow cytometry. In addition, the activation of apoptosis pathways was evaluated using BCL2, BAX, and Caspase-3 (CASP3) gene expression and ratio of BAX to BCL2 (BAX/BCL2). Finally, in silico study was performed to suggest the molecular mechanism of this combination therapy on melanoma cancer. Results showed that although combination therapy with CUR and CAP has cytotoxic and apoptotic effects on cancer cells, it did not improve apoptosis rate in melanoma B16-F10 cancer cells compared to monotherapy with CAP or CUR. In addition, evaluation of gene expression in cancer cell line confirmed that CUR and CAP concomitant treatment did not enhance the expression of apoptotic genes. In silico analysis of docked model suggested that CUR blocks aquaporin- (AQP-) 1 channel and prevents penetration of CAP-induced ROS into the cells. In conclusion, combination therapy with CAP and CUR does not improve the anticancer effect of each alone.

The study of Iranian children and adolescents' physical activity: a systematic review and meta-analysis.

OBJECTIVES: This systematic and meta-analysis review was conducted to determine the status of Iranian children and adolescents' physical activity. CONTENT: All the related articles which were published in the major databases, including Pubmed, Scopus, Web of Science, Embase, Magiran, SID from the beginning of 2010 to the end of 2019, were reviewed by researchers. The Newcastle-Ottawa scale was also used to evaluate the quality of articles. Moreover, I 2 index and chi-square were used to assess the heterogeneity between the results. SUMMARY: 490 articles were found as a result of the search in the selected international and local databases, where finally, 10 articles were included into the meta-analysis after the elimination of the duplicated articles and applying inclusion and exclusion criteria. The results indicated that 29.5% of the girls were considered active according to WHO criteria (16.1-42.8: 95% CI) and also 20.5% of the boys (7.3-33.7: 95% CI). OUTLOOK: Overall, this study's findings showed that a large percentage of Iranian children and adolescents do not achieve the level of physical activity recommended by the World Health Organization. This can lead to undesirable consequences for this group of population that is considered as the human capital of any country; consequently, it seems necessary to take basic measures at the micro and macro levels in order to reduce such problems in the society.

The effect of online multimedia psychoeducational interventions on the resilience and perceived stress of hospitalized patients with COVID-19: a pilot cluster randomized parallel-controlled trial.

BACKGROUND: There is evidence suggesting that quarantine might have undesirable psychological impacts on the patients. Therefore, it is important to seek for ways to increase the resilience and alleviate the psychological pressure of the patients who are quarantined due to infection with COVID-19. The present study was conducted to assess an online multimedia psychoeducational intervention regarding the feasibility, adherence, patient satisfaction and effectiveness on resilience and perceived stress of patients hospitalized with confirmed COVID-19. METHOD: This was a pilot cluster randomized parallel-controlled trial with hospital wards as the units of randomization. Participants in this fully online trial were 50 consecutive patients who were hospitalized in 2 hospitals in Shiraz, after being diagnosed with COVID-19. Before the beginning of the intervention, four inpatient wards inside two of the hospitals were randomly assigned to either intervention or control conditions. All eligible participants in the wards allocated to the intervention condition received online multimedia psychoeducational interventions during the 2 weeks, whilst the patients in the wards allocated to the control condition were offered the opportunity to receive telephone-based psychological counseling if needed. Psychoeducational interventions mainly included cognitive-behavioural techniques, stress management techniques, mindfulness-based stress reduction and positive psychotherapy. The patients were assessed regarding resilience and perceived stress at baseline and after two weeks. RESULTS: Of 27 patients starting multimedia psychoeducational interventions, 26 (96.29%) completed post-assessments. A high level of adherence (80.76%) and satisfaction (Mean = 29.42; SD = 4.18) with the online multimedia psychoeducational interventions was found. Compared with the control group, the patients who used online multimedia psychoeducational interventions reported greater resilience (Meanintervention = 81.74; Meancontrol = 72.86; adjusted t (46) = 2.10; p = 0.04; CI: 0.39 to 17.38; dppc2 = 0.83) and fewer perceived stress (Meanintervention = 22.15; Meancontrol = 29.45; adjusted t (46) = 2.66; p = 0.01; CI: - 12.81 to - 1.78; dppc2 = - 0.77) after 2 weeks. DISCUSSION: The findings of the present study provided a successful first attempt at implementing feasible online multimedia psychoeducational interventions to promote resilience and mitigate stress among the patients who were hospitalized due to infection with COVID-19. The present results could help mental health professionals to determine which psychological techniques should be emphasized to promote patients' resilience in the context of COVID-19 disease.

Comparison of the Effectiveness of Combined Diode Laser and GLUMA Bonding Therapy With Combined Diode Laser and 5% Sodium Fluoride Varnish in Patients With Dentin Hypersensitivity.

Introduction: Dentin hypersensitivity (DH) is one of the most common complaints of patients referred to a dental office, so this study aimed to compare the effectiveness of combined diode laser and GLUMA bonding therapy with combined diode laser and 5% sodium fluoride varnish in patients with DH. Methods: Sixty patients were divided into three groups (bonding, laser-bonding, laser-varnish), and before the intervention, the amount of DH was measured with the visual analogue scale (VAS) scale. In the bonding group, GLUMA Desensitizer solution was applied and then air-dried. In the bonding-laser group, first bonding was used, and then the affected tooth was irradiated with a diode laser. In the varnish-laser group, 5% sodium fluoride varnish was coated and then the laser was irradiated with the said method. DH was measured immediately after the treatment and then 2, 7 and 30 days after the treatment. Results: Laser-varnish treatment was not different from laser-bonding treatment at all measurement times (P=1). Laser-varnish and bonding treatment were not significantly different up to one week after the intervention, but on the 30th day after the intervention, the difference in pain was significant (P=0.01). There was no significant difference in laser-bonding treatment up to one week after the intervention, but on the 30th day after the intervention, the difference in pain was significant (P=0.003). Conclusion: The combined treatment with GLUMA bonding and the 660 nm diode laser is effective in reducing DH and this is more effective than GLUMA bonding alone in the long term. However, it does not have a significant advantage over the combined varnish-laser method, but it seems that due to its ease of use, it can be a suitable alternative to the varnish-laser method.

Design an Efficient Multi-Epitope Peptide Vaccine Candidate Against SARS-CoV-2: An in silico Analysis.

BACKGROUND: To date, no specific vaccine or drug has been proven to be effective against SARS-CoV-2 infection. Therefore, we implemented an immunoinformatic approach to design an efficient multi-epitopes vaccine against SARS-CoV-2. RESULTS: The designed-vaccine construct consists of several immunodominant epitopes from structural proteins of spike, nucleocapsid, membrane, and envelope. These peptides promote cellular and humoral immunity and interferon-gamma responses. Also, these epitopes have a high antigenic capacity and are not likely to cause allergies. To enhance the vaccine immunogenicity, we used three potent adjuvants: Flagellin of Salmonella enterica subsp. enterica serovar Dublin, a driven peptide from high mobility group box 1 as HP-91, and human beta-defensin 3 protein. The physicochemical and immunological properties of the vaccine structure were evaluated. The tertiary structure of the vaccine protein was predicted and refined by Phyre2 and Galaxi refine and validated using RAMPAGE and ERRAT. Results of ElliPro showed 246 sresidues from vaccine might be conformational B-cell epitopes. Docking of the vaccine with toll-like receptors (TLR) 3, 5, 8, and angiotensin-converting enzyme 2 approved an appropriate interaction between the vaccine and receptors. Prediction of mRNA secondary structure and in silico cloning demonstrated that the vaccine can be efficiently expressed in Escherichia coli. CONCLUSION: Our results demonstrated that the multi-epitope vaccine might be potentially antigenic and induce humoral and cellular immune responses against SARS-CoV-2. This vaccine can interact appropriately with the TLR3, 5, and 8. Also, it has a high-quality structure and suitable characteristics such as high stability and potential for expression in Escherichia coli .
