Abstract

Abstract Background: Aloe Vera species have diverse immunomodulatory and antitumor activities. The present study was set out to define the immunomodulatory activity of Aloe Vera extract on tumor necrosis factor-alpha (TNF-α) and development of experimental autoimmune encephalomyelitis (EAE) as an animal model of multiple sclerosis (MS). Materials and Methods: In this experimental interventional study, EAE was induced by MOG35-55 peptide and complete Freund's adjuvant in C57BL/6 mice. Mice were placed in two therapeutic groups (n=8 per group) with the same age and weight. Therapy with Aloe Vera extract (120mg/kg/every day given oral) was started on day 5 before the immunization until 25 day after that. EAE control received phosphate buffer alone with same schedule. Signs of disease were recorded daily until the day 25 when mice were bled and sacrificed. Produced TNF-α by cultured spleen mononuclear cells was detected by ELISA. Results: The Aloe Vera treatment significantly reduced the clinical signs of EAE and delayed onset of disease. Mononuclear cells isolated from spleen of treated-mice with Aloe Vera showed a significant decrease in TNF-α in compared with control mice (p=0.012). Conclusion: Aloe Vera ameliorated the EAE and reduced TNF-α level in MS animal model.

Abstract

Background: The aim of this study was to determine the effect of preconception endurance exercise training with voluntary exercise activity during pregnancy in mother mice on lipid profile in adult offsprings.

Materials and Methods: Twenty four C57BL/6 female mice were randomly divided into four subgroups: trained in preconception period and exercised during pregnancy (TE)(20.3±1.02g); trained in preconception periods but unexercised during pregnancy (TC)(21.58±0.4g); untrained in preconception periods but exercised during pregnancy (CE)(21.02±0.23g); untrained and unexercised (CC)(19.23±0.45g). Trained mice were subjected to a protocol of moderate endurance exercise training over a period of 4 weeks for 5 days before pregnancy. The fasting blood samples were collected from adult mice(8 weeks old) and serum levels of glucose and lipid profile were measured. Data were analyzed using two way ANOVA and Tukey’s post hoc test.

Results: The Glucose test results in offspring showed that there was a significant interaction between group and sex and group main effect (p<0.001) Glucose levels of male offspring were significantly lower in TC and TE groups. Results on LDL also showed that the sex main effect was significant (p<0.001), and LDL levels of male born to TE and TC dams lower than in female offspring.

Conclusion: Improving the mother's physical fitness by providing regular endurance training in the preconception period and maintaining it by exercise activty throughout pregnancy may have potential for eliciting positive changes in lipid profile of offspring, specially males.

Abstract

Abstract

Background: Prevalence extension of antibiotic resistant bacteria has raised concerns about control of infections especially nosocomial infections. Many attempts have been done to replace antibiotics or limit their use. The use of antimicrobial agents produced by bacteria as antibiotic replacement has been promising in recent years. The goal of this study was to isolate Bacillus strains and evaluate their antimicrobial activity against some standard pathogens and clinical antibiotic resistant strains.

Materials and Methods: In the present study, Bacillus strains were isolated from various resources and identified by 16S rDNA PCR method. Then, the phylogenetic tree of the isolates was constructed and antimicrobial activity of the isolates was investigated against some standard pathogens and clinical antibiotic resistant strains using spotting and well diffusion methods.

Results: Eight Bacillus strains were isolated from 15 different samples. Based on the molecular identification, the isolates were identified as B.pumilus, B.coagulans, B.licheniformis, B.endophitycus and B.amiloliquefaciens. The results showed that isolates have antimicrobial activity against meticilin-resistant Staphylococcus aureus, vancomycin resistant enterococci, Klebsiella, Acinetobacter, Salmonella, Shigella, Listeria, Streptococcus and Escherichia coli.

Conclusion: In this study, isolated Bacillus strains produced antimicrobial agents against pathogens and antibiotic resistant strains and inhibited their growth.

  1. Abstract
  2. Background: Students face a lot of emotional problems and psychological stress that affect their individual and social adaptation as well as their quality of life. Therefore, examining treatment models for these problems is very important. One of these models, the Fractal Diagnostic Treatment Model, is based on emotional regulation skills for a wide range of emotional disorders that can be used properly. The purpose of this study was to investigate the effectiveness of integrated diagnostic therapy on individual and social adaptations and emotional adjustment.
  3. Materials and Methods: A total of 70 female students were selected and assigned into two diagnostic groups (35 patients) and control (35 people). The experimental group received 12 sessions of diagnostic diagnosis weekly. Data were gathered in this study by Social Compliance Scale and Graz's Regulatory Emotion Questionnaire. Data were analyzed using descriptive statistics and multivariate covariance analysis (MANCOVA).
  4. Results: The results showed that transdiagnostic treatment focused on the dimensions of emotional regulation, including: refusal of emotional responses (F = 120.69, p < 0.01), impulse control problems (F = 14.57, p < 0.01), lack of emotional awareness (F =104.82, p< 0.01), lack of emotional resolution (F=42.64, p< 0.01), participation problems (F = 41.00, p<0.01), and limitations in achieving emotional regulation (F = 85.33, p<0. 01) is effective. Also, the results showed that exacerbation-based fetal diagnostic therapy was effective on individual adaptations (F = 146.76, p < 0.01) and social (F = 85.02, p<0.01).
  5. Conclusion: Regarding the effect of Fract-Intervention therapy based on emotional adjustment on personal and social adaptation and student's emotional adjustment dimensions, these results are applicable to clinical practitioners, counselors and practitioners in academic counseling centers.

Abstract

Introduction: Dental unit water lines (DUWL) are a potential place for the accumulation of microorganisms and the formation of microbial biofilm, which exposes people to infection risk. This study aimed to investigation of the effectiveness of four commonly used substances and selection of most effective disinfectant in DUWLs disinfection.
Methods: This systematic review study was conducted based on PRISMA templates and the PubMed, Scopus and Web of Science databases with a specific search strategy were examined. In this systematic review study, the effectiveness of 4 disinfectants including: hydrogen peroxide, chlorhexidine, chlorine-dioxide, sodium hypochlorite on microbial biofilms in the DUWL was investigated. The study was conducted on July 10, 2021, and finally the data of all studies related to the subject of this systematic review were extracted. This study was approved by the Research Ethics Committee at Arak University of Medical Sciences (Code: IR.ARAKMU.REC.1399.347).
Results: All four disinfectants in sufficient concentration and time can be useful and effective. If the biofilm in DUWL is old and stabilized, it will affect the effectiveness of these materials and it will take longer to remove.
Conclusions: The use of materials in combination can cover all the microbial spectrum present in the biofilm of this area, and even fixed biofilms can be removed with extended and continuous use.
