Abstract
Backgrounds and Objectives: Afew large population-based studies have been conducted on the prevalence of oral mucosal lesions in relation to fertility status in the Iranian population. The aim of study was determine the prevalence of oral mucosal lesions in relation to fertility status in women participants of Shahedieh cohort study.
Materials and Methods: A descriptive cross-sectional study was conducted on 4935 women who participated in the Shahedieh cohort study. The age range of participants was 35-71 years with a mean age of 47.12 years. The prevalence of oral mucosal lesions considering fertility variables including pregnancy, number of pregnancy, oophorectomy, tubectomy, hysterectomy, infertility, menopause, normal menopause, and abortion, application of infertility and oral contraceptive drugs and hormone replacement therapy were recorded.
Results: The total prevalence of oral mucosal lesions in the studied women were 3.8%. The most commonly affected age group was 40-49 years, followed by 30-39, 50-59 and 60-71 years, respectively. Considering the fertility variables, only menopause (P=0.047) and normal menopause (P=0.024) significantly related to the prevalence of oral mucosal lesions.
Conclusions: The findings of the present study provide information on the prevalence of the oral mucosal lesions considering fertility status in a large population-based study in Iran. With due attention to the higher prevalence of oral mucosal lesions in menopause women, an improved comprehension of oral manifestations at menopause and preventive and treatment approaches during this period should be programmed with health care services to meet the needs of patients deservingly.

Abstract
Background and objectives: patients undergoing Chemotherapy are severely susceptible to infections due to a compromised immune system and also their oral cavity is a great place for microorganisms and fungi to grow. The aim of this study was to determine the distribution of different strains of Candida from oral lesions of these patients.
Methods and Materials: This descriptive study was performed on 128 patients undergoing chemotherapy in teaching hospitals of Yazd, which was three weeks pass receiving their first medicine. Oral samples were prepared from swabs and then cultured in Sabouraud dextrose agar culture media for evaluation of yeast growth, colonization, and identification of species. Samples were examined under the microscope and recorded. Finally, the data were analyzed by SPSS17 software, Chi-square, and Man-Whitney tests.
Results:128 patients participated in this study, which included 45 males (35.15%) and 83 females (64.85%) with an average age of 40.16 ± 19.95 years. 84 patients (62.65%) had candida in their oral cavity, of which 79 were candida albicans and 5 were Non-albicans Candida. No significant correlation was found between the type of candidates, type of cancer and the frequency of Candida albicans with the age and sex of the patients (P-value <0.05).
Conclusion: Based on the results of this study, the prevalence of Candida albicans in patients undergoing chemotherapy is higher than Non-albicans Candida. Patients with leukemia are more susceptible to Candida infections.

Abstract
Background and objectives: Most studies have identified interferon-gamma (IFN-γ) as a key role in the pathogenesis of oral lichen planus (OLP). Recent studies have also shown a link between IFN-γ (+874 A/T) gene polymorphism and OLP. The purpose of the present meta-analysis is to investigate the relationship between IFN-γ (+874 A/T) gene polymorphism and susceptibility to OLP.
Methods: A systematic search of resources to investigate the association between IFN-γ and OLP from Google scholar, PubMed, Embase, Cochrane, Scopus, Proquest, Ovid and Web of science (from 2000 to April 2019) completed. Two individuals independently assessed the quality of the articles. Endnote X5 resource management software was used to organize, study titles and abstracts as well as identify duplicates. A random effect model was also used to perform the meta-analysis.
Results: Four IFN-γ (+874 A/T) polymorphism studies with 297 patients in the case group and 621 healthy controls in the 4 different countries were included. After meta-analysis, a significant association was found between IFN-γ polymorphism (+874 A/T) and OLP. (T vs A: odds ratio (OR) = 1.62; 95% CI = 1.28-2.04; TT vs AA: OR = 2.67; 95% CI = 1.6- 4.45; AT vs AA: OR = 1.56; 95% CI = 1.6- 4.45; TT vs AT + AA: OR = 1.73; 95% CI = 1.13-2.64; AT + TT vs AA: OR = 1.75; 95% CI = 1.28-2.43)
Conclusion: Based on this meta-analysis, there was a positive relationship between IFN-γ (+874 A/T) gene polymorphism and the risk of OLP. The findings showed that increasing TT genotypes significantly increased susceptibility to OLP in comparison with other genotypes.

Abstract
Background and objectives: It has been reported that deep-fried oils (DFOs) used in the preparation of fast foods can affect the immune system. On the other hand, regular physical activity and proper nutrition, in addition to affecting physical function, have a tremendous impact on the immune system. The aim of the present study was to investigate the anti-inflammatory effects of aerobic training (T) and octopamine (O) consumption in the heart tissue of rats fed DFO.
Methods: In this experimental study, 25 male Wistar rats with mean age of 20 weeks old and weighing 300- 350 were purchased and divided into 5 groups of 5 rats, including: 1) control, 2) DFO, 3) DFO+T, 4) DFO+O and 5) DFO+T+O. During four weeks, groups 2- 5 received DFO by gavage; groups 3- 5 ran on treadmill (with speed of 50% Vo2max in the first week which reached 65% Vo2max in the last week) five sessions per week and 20 minutes per session and groups 4-5 received 81 μmol/kg octopamine supplement peritoneally for 5 days per week. Nuclear factor kappa B (NF-κB) and tumor necrosis factor-alpha (TNF-α) gene expression were measured in heart tissue.
Results: DFO significantly increased NF-κB (P=0.005) and TNF-α (P=0.001) gene expression levels; T significantly on decreased NF-κB (P=0.01) and TNF-α (P=0.007) gene expression levels; O consumption significantly decreased NF-κB (P=0.001) and TNF-α (P=0.001) gene expression levels; however, the interactive effects of T and O consumption on NF-κB (P=0.57) and TNF-α (P=0.20) gene expression levels was not significant.
Conclusion: It seems that T and O consumption alone have anti-inflammatory effects on the heart tissue of rats fed DFO, however T and O do not have anti-inflammatory interactive effects.

Abstract
Background and objectives: Controlling nutrition and exercise can be two important strategies in controlling tendon health. It has been reported that resistance training and palm pollen separately can improve Scleraxis (Scx) in tendon tissue; so present study aimed to investigate the interactive effects of resistance training with ethanolic extract of palm pollen on Scx protein and gene expression levels in the tendon tissue of male adult rats.
Methods: In this experimental study 30 male adult rats divided into 6 groups of 6 rats including: 1) sham, 2) training, 3) palm pollen, 4) testosterone, 5) training + palm pollen, and 6) training + testosterone. During 4 weeks, groups 2, 5, and 6 performed resistance trainings for five sessions per week; groups 3 and 5 received 100 mg/kg palm pollen for five days per week via gavage and groups 4 and 6 received 2 mg/kg testosterone propionate peritoneally. Scx protein and gene expression levels were measured in tendon tissue by Western blot and real-time PCR methods respectively. Shapiro- Wilk, one way ANOVA with Tukey’s post- hoc tests were used to analyze the findings (P≤0.05).
Results: Training significantly increased Scx protein levels (P=0.005); palm pollen significantly increased Scx gene expression levels (P=0.001); training + palm pollen significantly increased Scx protein and gene expression levels (P=0.001) also training + palm pollen had more favorable effect on increase of Scx protein and gene expression levels compared to training and palm pollen alone (P=0.001).
Conclusion: It seems that resistance training simultaneously with palm pollen administration can have a more favorable effect than each one alone on improving Scx protein and gene expression levels in tendon tissue of male adult rats.

Abstract
Background and objective: Exercise and nutrition are two factors influencing the improvement of inflammatory markers in patients with colon cancer. Aim of present study was to investigate the effect of aerobic training (AT) with Purslane (Portulaca Oleracea) Seed (PS) on toll like receptor 2 (TLR-2) and TLR-4 in colon tumor tissue of rats with colon cancer.
Methods: In this experimental study 30 adults rats were divided into five groups of six rats including: 1) healthy control, 2) control, 3) training, 4) PS, and 5) training + PS. Colon cancer induced by intra-peritoneal injection of azoxymethane in groups 2- 5. During eight weeks, groups 3 and 5 performed AT for five sessions per week also groups 4 and 5 received 75 mg/kg PS intra-peritoneally. TLR2 and TLR4 protein levels were measured by ELISA method. For review the normal distribution and data Shapiro- wilk was used and for statistical analysis of data one way ANOVA with Tukey’s post- hoc tests were used (P≤0.05).
Results: Training had not significant effect on TLR-2 (P=0.91) and TLR-4 (P=0.95); PS and training + PS significantly decreased TLR-2 and TLR-4 (P=0.001) also training + PS had more favorable effect on decrease of TLR-2 compare to training and PS alone (P=0.001).
Conclusion: Although PS alone can improve TLR-2 and TLR-4 levels in colon tumor tissue of adult rats with colon cancer, nevertheless it appears that AT along with PS have more favorable effects on improvement of TLR-2 compare to training and PS alone.

Abstract
Background and objective: Prevalence and the spread of novel Coronavirus (2019-ncov) cause significant life and financial destruction worldwide and is the cause of severe respiratory infection in humans. The present study briefly reviews the latest information on how the virus is distributed around the world. The main question of the study are: 1- In which geographic regions of the world is the Coronavirus more concentrated? 2- Is the distribution of the Coronavirus geographically stable?
Material and Methods: To answer these questions, we first began collecting and studying the available scientific resources. The required data was obtained from a daily report of confirmed, recovered, and deaths by the Coronavirus separated by state which was collected from January 22, 2020 to Jun 19, 2020. Based on analyzing available patterns in spatial statistics tool in ArcGIS and geostatistical models, we examined how the Coronavirus was distributed around the world.
Results: The spread of the disease is increasing all over the world. Using the results of Map 1, it is seen that the spread of Corona virus has a trend and starts in China and then spreads to the Middle East, Europe and the United States in a linear manner. The results also show that the prevalence of mortality is higher than that of recovery. Central mean and median for all types (Confirmed, Recovered and death) are close to each other. Death mean and median was close to Western countries and Recovered mean and median was close to Eastern countries, while confirmed mean and median was located in the center.
Conclusion: Based on spatial statistics tool in ArcGIS and geostatistical models, we examined how the Coronavirus was distributed around the world. Our results showed that the spread of Corona virus had a trend and started in China and then spread to the Middle East, Europe and the United States in a likely linear manner.

Abstract
Background and objective: The effect of aerobic exercise (AE) on cardiovascular (CVD) related risk factors are still debatable. Therefore this randomized controlled clinical trial (RCT) was performed with unique and specific AE protocol to investigate the effect of eight-week AE only on female subjects with type 2 diabetes.
Material And Method: A controlled RCT was performed on 30 women with type 2 diabetes aged 30 - 50. They were randomly divided into two groups, intervention and control by block randomization method. The intervention group received an incremental AE for eight weeks, three sessions per week, max heart rate (55-75%) and rating of perceived exertion (RPE) 12-13 for 150 minutes per week. Blood samples were taken before and after each intervention for both groups to be evaluated for fasting blood sugar (FBS), hemoglobin A1c (HbA1c), lipid profile [triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C)].
Result: Eight-week AE intervention led to a significant decrease in HbA1c, FBS levels (p = 0.025, p=0.003) in experimental group compared to control however no significant differences was observed in terms of lipid profile (total cholesterol (TC), triglyceride (TG), LDL-C and HDL-C) between control and experimental group (p> 0.05). The results of paired t-test showed that FBS, TC and HbA1c levels were significantly reduced within experimental group after intervention compared to pre-test (p = 0.038, p = 0.05, p = 0.002, respectively). There was no significant difference between TG, LDL-C, and HDL-C levels within experimental group between pre and post-test (p>0.05).
Conclusion: It can be concluded that AE has been effectively reduce FBS, HbA1c and TC in women type 2 diabetes.

Abstract
Background and Objective: Reports indicate that over 60% of people with diabetes die from cardiovascular diseases. The present study was conducted to investigate the interactive effects of resistance training and genistein consumption on the serum levels of vascular cell adhesion molecule 1 (VCAM-1), intercellular adhesion molecule 1 (ICAM-1) and C-Reactive Protein (CRP) in diabetic rats with streptozotocin.
Material And Methods: In this experimental study, 40 diabetic rats were selected and divided into 5 groups of 8 subjects, including: (1) control, (2) sham (dimethyl sulfoxide), (3) resistance training (4), genistein consumption, and (5) resistance training and genistein consumption. Rats in groups 3 and 5 received 8 weeks of resistance training, 3 sessions per week, with 30 to 100% body weight, and rats in groups 4 and 5 received 30 mg/kg of peritoneal genistein per day. Data were analyzed using independent sample t-test and two-way ANOVA in SPSS software (p≤0.05).
Results: Genistein consumption has a significant effect on reduced serum levels of VCAM and ICAM in diabetic rats (p≤0.05). Eight weeks of resistance training has a significant effect on reduced serum levels of ICAM and CRP in diabetic rats (p≤0.05). Resistance training and genistein consumption have interactive effects on reduced serum levels of VCAM and CRP in diabetic rats (p≤0.05).
Conclusion: Resistance training and genistein consumption simultaneously appear to reduce the risk of atherosclerosis in diabetic rats.

Abstract
Background and Objective: Effects of resistance training and herbal supplements on cardiac signaling pathways are sparsely reported in the literature. This study aimed to evaluate the CITED4 gene expression in the cardiac muscle of male rats as a result of resistance exercise and spirulina supplementation.
Material and Methods: Thirty-two rats (male - Sprague Dally) were grouped into 4 groups (1. resistance training: RE, 2. spirulina + resistance training: SP +RE, 3. spirulina platensis: SP, 4. control: Co, n = 8). The training program was performed for healthy training groups 5 sessions per week for 8 weeks. Supplementation included 200 mg/kg/ day of Spirulina for the supplement groups. Real-time PCR was used to measure gene expression. We used of Two-way ANOVA in SPSS (p<0.05).
Results: In comparison with the control group, we observed a significant increase in CITED4 gene expression in RE (P= 0.001) and RE+SP (P= 0.001) groups. Also, there was a significant difference in CEBP gene expression between CO with RE (P= 0.001), SP (P= 0.034), RE+SP (P= 0.001) groups.
Conclusion: Spirulina supplementation alone has no effect on the signaling pathway of cardiac hypertrophy. However, if used concomitantly with resistance training, it can affect the signal pathway of cardiac hypertrophy.

Abstract
BBackground and Objective: Pseudomonas aeruginosa is an important case of nosocomial infections and a major health problem. The increased emergence of resistance to antibiotics and disinfectants among these bacteria, necessitates the production of new antimicrobials with wider activity and low toxicity. This study was carried out to evaluate inhibitory effects of chlorhexidine gluconate and extract of Peganum harmala on multi-drug resistant (MDR) P. aeruginosa.
Material and Methods: 39 P. aeruginosa strains were isolated from 114 environmental samples. After identifying MDR strains, minimal inhibitory concentration (MIC) of chlorhexidine gluconate (20%) and P. harmala extract against the isolates was determined by broth microdilution method.
Results: Overall, 27 (69.2%) P. aeruginosa isolates resistant to quinolones, aminoglycoside, cephems and carbapenems were reported as MDR strains. The MIC of chlorhexidine gluconate was ≥ 1000μg/ml, which was 4-fold higher than the MIC of P. harmala extract (MIC=500μg/ml). MIC of chlorhexidine gluconate and P. harmala extract against P. aeruginosa isolates differed significantly (P=0.01).
Conclusion: Compared to chlorhexidine gluconate, P. harmala extract has a higher antibacterial effect on MDR P. aeruginosa isolates from environment. Further research is required to verify the efficacy of this plant extract for disinfection of equipment in clinics and local kitchens.

Abstract
Date Palm Pollen (DDP), which is found in the male date tree, actually fertilizes the female date tree, which is necessary for the growth of date fruit. It is consisting of sugarcane, protein, calcium, vitamins (B, C and E) and minerals. It has long been used in traditional medicine as a medicinal plant with fertility effects and increased libido. The information obtained from the studies shows that this pollen, due to its antioxidant and gonadotropin-stimulating compounds, can increase fertility and sexual potency in both women and men with two main mechanisms. The first mechanism is this effect on the stimulation of gonadotrophic hormones and the second is a reduction of oxidative stress in the testicular tissue and consequently a protective effect on the testicular tissue. Due to the presence of antioxidant compounds, the consumption of this pollen also applies its health-enhancing effects to other tissues such as the liver, intestines, and heart. As same as DDP, regular Physical Activity (PA) stimulates gonadotrophic hormones and also beneficially affects antioxidant status and redox balance. In recent years, researchers have paid attention to this pollen as an important factor to strengthen the health-enhancing effects of PA, and researchers have investigated the simultaneous effect of this pollen and PA. Despite the few studies done, it seems that this pollen can enhance the antioxidant and anti-inflammatory effects of regular PAs. Nevertheless, it seems necessary to further studies in this area.

Abstract
Background: Genetic polymorphisms are predictors of the immune response and susceptibility to certain infectious diseases, including pulmonary tuberculosis (TB). We evaluated the association of monocyte chemoattractant protein-1 (MCP1) (-2581 A/G) and interferon-gamma (IFNγ) (+874 T/A) polymorphisms with susceptibility to pulmonary TB in an Iranian population.
Methods: A total of 124 patients with pulmonary tuberculosis and 244 healthy subjects (121 related normal controls and 123 unrelated subjects) were included. The MCP1 polymorphic region (-2518 A/G) was genotyped by PCR-RFLP, while ARMS-PCR was used to amplify and detect IFNγ (+874 T/A). SNPStats and SPSS v. 20 were used for the statistical analysis of the data.
Results: The comparison of MCP1 (-2518 A/G) alleles and genotypes in TB patients and healthy subjects showed no significant association in all the constructed heredity models. No association was observed between TB patients and normal subjects in all the constructed inheritance models for IFNγ (+874 T/A) alleles and genotypes.
Conclusion: Due to the lack of association between MCP1 (-2518 A/G) and IFNγ (874 T/A) polymorphisms and susceptibility to PT in our study and the conflicting results of some previous studies, further clinical and molecular research is needed to clarify the role of the studied polymorphisms in the pathogenesis of tuberculosis.

Abstract
Background: In medical research and survival analysis, it is common for an individual or item's failure to be attributable to multiple causes, also known as competing risks. This article focuses on examining the competing risks model as the data increasingly becomes type II censored and randomly removed. The model assumes that the causes of failure are independent and that the lifetimes of individuals are described by the Cox model. At each failure time, the number of items or people removed follows a binomial distribution. The article derives estimators for the indefinite parameters in the model. The study presents a set of detailed data and includes a simulation study that also illustrates the results.
Methods: Different reasons, frequently known as competing risks, are frequently embroiled in an individual's or an item's failure in medical research survival analysis. The competing risks shown under sort II dynamic censoring with random removals are the subject of this research.
We get the maximum likelihood and inexact most extreme probability estimators of the obscure parameters. The asymptotic distribution of the maximum probability estimators is utilized to decide the CIs. Then, Monte Carlo simulations were applied to demonstrate the approach. The analyses were performed utilizing R 4.0.4 software.
Results: For stroke, systolic blood pressure (SBP) and hypertension status are the only significant variables. In contrast, gender, body mass index (BMI), smoking status, the logarithm of urinary albumin and creatinine ratio, and diabetes status are significant variables for coronary heart disease (CHD) and other cardiovascular diseases (CVDs). The results suggest that significant risk factors differ for different types of CVD events.
Conclusion: The outcomes of the simulation study indicate that progressively right-censored type II sampling designs outperformed the usual censored type II sampling designs. Therefore, the estimated parameters on the defined pattern setting are recommended. They can be used in many practical situations when competing risks occur, and progressive censoring could be considered.

Abstract
Background: Type 2 diabetes is a metabolic disease associated with a partial or absolute deficiency of insulin, hyperlipidemia, and impaired metabolism of carbohydrates, fats, and proteins.
The present study aimed to compare the effects of different types of exercises on lipid profiles in menopausal women with type 2 diabetes.
Methods: Fifty-six sedentary obese menopausal women with type 2 diabetes were randomly divided into 4 groups: aerobic exercise, resistance exercise, combined exercise, and a control group. Each group, except the control group, participated in their respective exercises for 8 weeks. Blood samples were collected from the subjects before and 48 hours after the training period. Data were analyzed using the analysis of variance (ANOVA) and paired sample t tests, with a significance level set at P≤0.05. All calculations were performed using SPSS v. 20.
Results: Triglyceride levels significantly decreased in the aerobic exercise (P = 0.017) and combined exercise (P = 0.0001) groups. Low-density lipoprotein levels significantly decreased in aerobic exercise (P = 0.034), resistance exercise (P = 0.003), and combined exercise groups (P = 0.009). Cholesterol levels significantly decreased in the aerobic exercise (P = 0.0001), resistance exercise (P = 0.030), and combined exercise (P = 0.01) groups. Additionally, high-density lipoprotein levels significantly increased in the aerobic exercise (P = 0.041) and combined exercise (P = 0.002) groups.
Conclusion: It appears that combined exercises, rather than resistance or endurance exercises alone, are a more appropriate intervention for improving lipid profiles in menopausal women with type 2 diabetes.

Abstract
Background: Resistance training and protein supplementation are known to increase protein synthesis and hypertrophy, primarily through the activation of the mTORC1 signaling pathway. However, mTORC1 activation in the kidneys can potentially lead to kidney disease. This study investigates the effects of eight weeks of resistance training combined with Spirulina platensis supplementation on the RAGs/Rheb/mTOR/S6K pathway in male rat kidneys.
Methods: In this study, 32 male Sprague-Dawley rats were divided into four groups: control (Co; n = 8), Spirulina platensis (SP; n = 8), resistance training (RE; n = 8), and Spirulina platensis + resistance training (SP+RE; n = 8). The resistance training group engaged in five sessions per week over eight weeks. Spirulina was administered at a dosage of 200 mg/kg/day to the supplement and SP+RE groups. Gene expression was analyzed using real-time PCR following the last training session.
Results: The mTOR gene expression significantly increased in the SP group (p = 0.01), while no significant changes were observed in the RE and SP+RE groups. Rheb gene expression did not show significant changes across any groups. Significant changes were noted in the RAGs gene in the SP group (p = 0.001), RE group (p = 0.047), and SP+RE group (p = 0.025). The S6K gene showed significant changes in the SP group (p = 0.01) but not in the other groups.
Conclusion: Spirulina supplementation may activate the mTORC1 signaling pathway in the kidneys, potentially contributing to kidney disease progression. However, combined resistance training and Spirulina supplementation did not show changes in mTORC1 expression, suggesting that this combination might prevent further kidney tissue damage in athletes.

Abstract
Background: When metabolic demands increase due to an obesity-induced high-fat diet (HFD), mitochondrial function is impaired, production can increase, and oxidative stress occurs. This type of stress has been shown to play a key role in various pathological conditions such as heart disease, hypertension, diabetes, chronic kidney disease, and cancers. This study aims to evaluate the impact of HFD and resistance training (RT) on oxidative stress biomarkers and cardiac health in rats.
Methods: In this experimental study, 21 male Wistar rats (weighing 200-300 g) were randomly and equally assigned into the following groups: control (CTRL), HFD, and HFD+ RT. Animals in the HFD groups received a high-fat diet for 23 weeks. During the treatments, rats in the HFD+ RT group, besides receiving a high-fat diet, performed the progressive RT protocol three times per week with 30- 100% of their body mass in the last eight weeks. At the end of the treatments, superoxide dismutase (SOD), glutathione peroxidase (GPX), total antioxidant capacity (TAC), and malondialdehyde (MDA) levels in cardiac tissue were measured by colorimetric method. The data were analyzed by one-way analysis of variance (ANOVA) and Tukey’s post hoc test at a significant level of P<0.05.
Results: HFD did not alter levels of SOD, GPX, TAC, or MDA in cardiac tissue. Cardiac SOD (P=0.021), GPX (P=0.024), and TAC (P=0.041) levels in the HFD+ RT increased significantly compared to the HFD group, but there was no significant difference in cardiac MDA levels between the three groups (P=0.438).
Conclusion: RT seems to improve cardiac tissue oxidative stress adaptations in an animal model fed with an HFD.
