Abstract
Background and Aim The use of allograft alone or in combination with other bone materials has significantly improved bone-augmentation procedures. Therefore, this study aimed to evaluate the effect of topical gentamicin solution (80 mg) with allograft on guided bone regeneration in defects in rat skull.
Methods & Materials Twelve Wistar mice were randomly divided into two groups, with 6 in each group. Three defects were created in their skulls, one filled with demineralized freeze-dried bone (DFDBA) allograft alone, the other with allograft with gentamicin 80 mg solution, and the third defect were left empty as a control group. After 4 and 10 weeks, the mice were killed for histological specimens. Histological and histomorphometric evaluations were performed to qualitatively and quantitatively assess bone formation, a new bone type made, new bone vitality, inflammatory response, connective tissue type, and angiogenesis.
Ethical Considerations This study was approved by the ethics committee of Arak University of Medical Sciences (Code: IR.REC.ARAKMU.1397.30).
Results At the end of 4 and 10 weeks after surgery, the average percentage of ossification in the area of defects was higher in the group that received allografts with gentamicin, and during this period, a significant difference was seen between these groups and the control group.
Conclusion According to the present study, the use of gentamicin in combination with DFDBA has a significant effect on bone regeneration in defects in the rat skull.

Abstract
Background and Aim The high use of pesticides has increased the concern about its possible harm to individual and environment health. Chronic exposure to pesticides has serious effects on different body organs even before the onset of clinical symptoms. In this study, we aim to evaluate clinical and biochemical characteristics of male workers in a pesticide production factory in Guilan province, Iran.
Methods & Materials This cross-sectional study was conducted on 99 male workers exposed to pesticide and 107 people without exposure who were employed in a pesticide production factory in Guilan and selected using a convenience sampling method in 2020. Their demographical data as well as clinical characteristics such as respiratory symptoms (cough, shortness of breath, etc.), neurological symptoms (fatigue, tremors, cramps, muscle weakness, etc.), psychological symptoms (sleep disorders, anxiety, etc.) and skin symptoms (redness, itching, etc.) were collected from the occupational health records of the workers. Finally, the biochemical parameters were compared between the two groups. Statistical analysis was performed in SPSS software, version 16.
Ethical Considerations This study was approved by the Research Ethics committee of Guilan University of Medical Science, Rasht, Iran (Code: IR.GUMS.REC.1399.632). Informed consent was obtained from all participants in this study.
Results The frequency of symptoms such as headache, itchy skin, cough, and sleep disorders was higher in the exposed group (P<0.05). Based on the biochemical findings, blood urea level, creatinine level, alkaline phosphatase, and fasting blood sugar level were significantly higher in the exposed group (P<0.05). Thrombocytosis was observed in 9.09% of exposed workers, which was higher in those with more than 11 years of work experience.
Conclusion Chronic exposure to pesticide can cause thrombosis, changes in biochemical parameters, and clinical symptoms. It is recommended that biological monitoring should be conducted in exposed workers at a shorter interval.

Abstract
Background and Aim The efflux pump in Pseudomonas aeruginosa inhibits the effect of ciprofloxacin by releasing quinolones out of the cell. It is important to find compounds to inactivate or inhibit its activity to continue using the antibiotics. The present study was done to investigate using sertraline as an efflux pump inhibitor in P. aeruginosa to reduce antibiotic resistance.
Methods & Materials P. aeruginosa strains were isolated from clinical sources and identified by routine microbiological methods. Resistance of the isolates to ciprofloxacin was evaluated by Kirby–Bauer test. Resistance breakdown was investigated by adding sertraline to the Moller Hinton agar medium and determining the zone of inhibition of ciprofloxacin. Minimum inhibitory concentration (MIC) by microplate dilution method and Minimum bactericidal concentration (MBC) by culture and MTT method were done for the isolates and ATCC 27853. The presence of the efflux pump was evaluated by the phenotypic method using sertraline and serial dilution method of the liquid medium in a microplate, on ciprofloxacin-resistant strains. The presence of the producing gene of this pump was determined by the genotyping method in resistant strains by performing PCR. The standard PAO1 strain of P. aeruginosa was used as a positive control.
Ethical Considerations This study was approved by the Ethics Committee of the Faculty of Medical Sciences of Islamic Azad University, Brojerd Branch (Code: IR.IAU.B.REC.1401.011).
Results Based on Kirby–Bauer test results, three strains were considered resistant to ciprofloxacin. MIC of drug-resistant strains was between 32 and 64 mg/ml and MBC was between 16 and 32 mg/ml. By performing electrophoresis on the PCR products, it was determined that the tested strains contained the mexA gene encoding the efflux pump. In the agar medium without sertraline, the zone of inhibition around the ciprofloxacin disc was zero, but after adding sertraline, the diameter of the halo increased to 25 mm. The minimum inhibitory concentration of ciprofloxacin in the isolates before adding 25 µg of sertraline was 128 µg/ml and after adding sertraline, it was 4 µg/ml.
Conclusion It was concluded that sertraline inhibited the efficiency of the efflux pump in resistant P. aeruginosa isolates and reduced ciprofloxacin resistance.

Abstract
Introduction: Salmonella infection (salmonellosis) is a common bacterial disease that affects the intestinal tract. Several methods like Multiplex or real-time PCR, ELISA, and Agglutination are used to identify these bacteria. However, normally rapid, cost effective and easy diagnostic methods such as agglutination test is recommended. In Iran, positive control antiserums used in diagnostic kits work based on polyvalent agglutination and are against O and H antigens. The purpose of this research was to produce specific anti-sera against O and H antigens for using in agglutination and ELISA kits.
Methods: New Zealand white rabbits were immunized by intravenous injections of inactivated bacterial O and H antigens adjusted to a cell density equivalent to a turbidity of a McFarland number 3 standard. Serum collection was performed 7 days after the last injection. Collected Antisera were tested with positive human specimens as well as cross-reaction antibodies. Absorption method was used to obtain specific anti-sera against O and H antigens. Produced Anti-O and Anti-H antibodies were mixed with bacterial H and O antigens respectively and incubated for 1 hours in 37˚c. The Mixture was centrifuged and the supernatant was collected. Furthermore, in order to use these antisera in specific kits such as ELISA, Immunofluorescence etc., purification methods like Ammonium sulphate precipitation, tangential Flow Filtration and Chromatography were performed. This study was approved by the ethics committee of Pasteur Institute of Iran (Code: IR.PII.REC.1399.006).
Results: Results of agglutination test before and after adsorption showed cross-reaction before adsorption and no cross-reaction with H and O antigens with monospecific antisera against O and H after adsorption, respectively. Moreover, high quality and quantity of mono-specific antibody was obtained after purification.
Conclusions: Serum-based assays are recommended for the timely diagnosis of the disease since these assays are specific, sensitive, inexpensive, and rapid. Therefore, the produced antiserum in the present research can be used in primary screening of salmonella infections based on agglutination tests which are cost effective and simple. In addition, purified anti-sera can be used in the development of ELISA and Immunofluorescence assays.

Abstract
Introduction: Years after the first successful kidney transplant, there are still many questions about the best immunosuppression regimen for these patients. Various studies have shown that long-term use of calcineurin inhibitor drugs can be associated with chronic nephrotoxicity and lead to irreversible damage to the transplanted organ. Therefore, the goal is to use immunosuppressive drugs and reduce the dose of calcineurin inhibitors as much as possible without increasing the risk of transplant rejection. This study aims to compare renal function, the rate of viral infections, and the occurrence of rejection after kidney transplantation in patients on two different treatment regimens including everolimus plus a low dose of calcineurin inhibitor against the standard protocol of calcineurin inhibitor along with mycophenolic acid in 60 kidney transplanted patients.
Methods: This clinical trial was conducted at Labbafinejad Hospital in Tehran between 2018-2019 on 60 kidney transplant patients aged 18 to 65 years and for 12 months.
Results: In terms of kidney function status based on GFR, except for the first month (P=0.02), there was no significant difference between the two groups in any of the time periods (P>0.05). Also, there was no statistically significant difference between the two study groups in terms of hospitalization length after transplantation and re-hospitalization during the study (P>0.05).
Conclusions: The results of this study showed that the everolimus regimen and low dose of calcineurin inhibitor can be used de novo in transplant patients without increasing the risk of rejection in them and at the same time it may be able to reduce the incidence of viral infections after transplantation.

Abstract
Introduction: Coronaviruses are mainly the cause of respiratory disease in humans, and among the known species, the coronaviruses that cause SARS, MERS, and Covid 19 cause severe respiratory disease. So far, no specific treatment has been found for these diseases. Considering the beneficial effects of medicinal plants as antioxidant and anti-inflammatory compounds, the use of herbal compounds can be effective in mild infection of coronaviruses.
Methods: PubMed database was used to search for articles containing the terms coronavirus, SARS, MERS, as well as human and herbal medicine. The inclusion criteria were all full articles with the mentioned keywords and the exclusion criteria were summary articles and articles presented in conferences. A total of 36 articles on human coronaviruses were found. Most of the studies were about SARS (SARS-CoV) with 26 articles (72.22%). Two articles (5.55%) were found about Covid-19 (SARS-CoV-2) and only one article (2.77%) about MERS (MERS-CoV). It should be noted that one study included SARS-CoV and MERS-CoV and six studies (16.66%) also investigated SARS, MERS and Covid-19 at the same time. Ethical principles have been respected in writing the article, according to the instructions of the National Ethics Committee and COPE regulations.
Results: Some medicinal plants have been identified with effective antiviral activity against SARS, MERS, and Covid-19 coronaviruses, including green tea, cinnamon, licorice, cure, sage, chives, rhubarb, nettle, and blackberry. Considering that these medicinal plants have already been used with different therapeutic effects in the human medicinal pharmacopoeia, it is recommended to conduct clinical trials on humans in order to achieve an effective dose against common human coronaviruses.
Conclusions: Although some medicinal plants have been recommended for use in the treatment of coronavirus respiratory syndrome in humans, the effects of these plants on other biological factors have not been studied, until now. It is necessary to evaluate their side effects simoultaneous with clinical trials and confirming the effectiveness of these compounds.

Abstract
Background and Aim: Diabetes is a type of metabolic disease and one of the most common endocrine diseases. Oxidative stress and inflammation play an important role in the development and progression of diabetes. mTOR signaling pathway play an important role in glucose homeostasis and proliferation of pancreatic beta cells. In the present study, the therapeutic effects of p-cymene on oxidative stress markers and expression of the mTOR gene in diabetic male Wistar rats were investigated.
Materials and Methods: Diabetes was induced by injecting 55 mg/kg body weight of streptozotocin. Biochemical analyses of pancreatic tissue and real-time PCR were done to investigate the effects of metformin (55 mg/kg body weight) and p-cymene (25, 50, and 100 mg/kg body weight) on the activities of catalase and glutathione peroxidase enzymes and mTOR gene expression.
Findings: Streptozotocin decreased catalase and glutathione peroxidase enzymes and decreased the expression of the mTOR gene in pancreatic tissue. Treatment with metformin or p-cymene improved the activities of catalase and glutathione peroxidase enzymes and the expression of the mTOR gene in a dose-independent manner.
Conclusion: Results indicate that p-cymene has antioxidant properties and can regulate the mTOR signaling pathway. Therefore, p-cymene may be effective for the treatment of diabetes alone or in combination with metformin.

Abstract
Introduction: Gestational diabetes is defined as hyperglycemia with onset or first diagnosis during pregnancy, with a lower frequency than general diabetes. Overweight and obesity, old age at the time of pregnancy, previous history of gestational diabetes, family history of type 2 diabetes, and race are risk factors for gestational diabetes. Recently, the relationship between two polymorphisms (rs9939609 and rs1421085) of Fat mass and obesity-associated (FTO) gene and the risk of gestational diabetes has been investigated in some studies with conflicting results. Therefore, our aim of the present study was to investigate the association study of rs1421085 and rs9939609 of the FTO gene on gestational diabetes.
Methods: In this case-control study, five cc of peripheral blood was collected from 100 cases with gestational diabetes and 116 control pregnant women from Taleghani Hospital in Arak, and then DNA was extracted. After designing the specific primers, the genotypes were determined by the Tetra ARMS-PCR method. Demographic information was compared with genotypes between the two groups were compared using SNPSTAT software.
Results: A significant correlation was observed between obesity, BMI before and during pregnancy, HbA1c, FBS, cholesterol, and triglyceride levels among mothers with gestational diabetes compared to healthy pregnant mothers P = 0.0001. According to data analysis, there was no significant association between rs1421085 and rs9939609 of the FTO gene with gestational diabetes.
Conclusions: Considering the conflicting results between the association of FTO gene polymorphisms with gestational diabetes, to better identify and understand the pathogenesis of the disease, more studies with a higher number of samples and more racial groups are needed. In the future, identifying the profile and locations of genetic susceptibility to gestational diabetes can be used in the patient's management.

Abstract
Introduction: The present study findings aimed to investigate the effect of exercises based on the American National Academy of Sports Medicine principles (NASM) on walking kinetics in piriformis syndrome in middle-aged men.
Methods: The current research was semi-experimental and laboratory-type. The statistical sample of the present study was 30 men with piriformis syndrome. Subjects were equally and randomly placed in two intervention and control groups. The intervention group performed NASM exercises for eight weeks. Before and after the exercises, the ground reaction force variables were measured using a Bartek force plate device with a sampling rate of 1000 Hz. Kinetic data were smoothed using a fourth-order Butterworth filter with a frequency cutoff of 20 Hz. For statistical analysis, analysis of variance and paired T-test were utilized at the significance level of P < 0.05.
Results: The findings of the present study showed that the effect of time on the FxHC and FyHC components at the peak of the forces and the FyHC component at the time of reaching the peak of the ground reaction force increased in the post-test compared to the pre-test. P > 0.025;
d = 0.64 - 0.96. The effect of the time factor in the FyPO component at the peak of the ground reaction force in the post-test was less than the pre-test (P < 0.025; d = 1.64-0.96). The interaction effect of the time × group in the FxPO component at the peak of the force and the FzHC component at the time of reaching the peak of the ground reaction force had a significant difference (P < 0.048; d = 0.87-0.83).
Conclusions: The NASM exercises used in this research can have a clinical and therapeutic effect that can reduce damage to the lower limbs and improve the quality of walking in people with piriformis syndrome.

Abstract
Introduction: Non-alcoholic fatty liver disease (NAFLD) is the most common liver disorder in industrialized societies. As an appetite inhibitory and energy balance regulator, nesfatin-1 plays a substantial role in the pathogenesis of obesity-related abnormalities. This study was conducted to determine the effects of 12 weeks of combined training (resistance training and high-intensity interval training (HIIT)) on the serum levels of nesfatin-1 and some liver enzymes in men with NAFLD.
Methods: In this semi-experimental study, 20 middle-aged men with NAFLD were randomly divided into two exercise and control groups. The exercise program included 12 weeks of combined training, featuring two sessions per week of resistance training and one session of HIIT. Body weight, body mass index (BMI), nesfatin-1 peptide, liver enzymes (ALT, AST, and ALP), lipid profile, maximal oxygen consumption (VO2max), and body fat percentage at the beginning and after 12-weeks were evaluated. Independent and dependent t-tests were analyzed to assess intra-group and inter-group differences, and the significance level was
P < 0.05.
Results: 12 weeks of combined resistance training and HIIT increased nesfatin-1 and decreased liver enzymes ALT, AST, and ALP in the exercise group compared to the control group and the pre-training stage (P < 0.05). We also observed an increase in VO2 max and a decrease in body weight, BMI, body fat percentage, and LDL in the exercise group compared to before starting the training protocol (P < 0.05).
Conclusions: Based on the results of the present study, it can be concluded that performing combined exercise training for twelve weeks led to an increase in nesfatin-1 peptide levels and a decrease in liver enzymes. It was suggested that this could be a cost-effective therapeutic approach recommended for patients with NAFLD.

Abstract
Introduction: Harmine is an alkaloid from the carboline family, belonging to the harmal plant, which has extensive applications in traditional medicine, with numerous studies highlighting its anti-cancer effects. Since biological processes are influenced by electromagnetic fields, the current study examined the anti-cancer effects of harmine and low-frequency electromagnetic fields on the expression of COX2, VEGF, and MMP-2 genes in the A2780 cell line.
Methods: In this experimental-laboratory study, ovarian cancer cell lines were randomly divided into four groups: control, harmine at concentrations of 6, 12, 24, 48, 96, and 192 micromolar, low-frequency electromagnetic field with an intensity of 50 Gauss, and harmine at a concentration of 48 micromolar with a low-frequency electromagnetic field of 50 Gauss intensity. Their toxicity was assessed using the MTT assay, nuclear morphological changes by DAPI staining, apoptotic effects of these compounds by measuring nitric oxide (NO), and gene expression changes by Real-Time PCR. Quantitative data were analyzed the ANOVA statistical test at a P < 0.05 level.
Results: Quantitative data comparison of this research indicated that harmine and a low-frequency electromagnetic field with an intensity of 50 Gauss caused a concentration-dependent reduction in the viability of ovarian cancer cells. Additionally, in the nitric oxide test, a significant decrease was found in the control group compared to the groups treated with a concentration of 48 micromolar and synergized with a 50 Gauss electromagnetic field (p<0.05). The expression of the aforementioned genes in treated cells showed a significant decrease. Treating ovarian cancer cells with harmine and its combined application led to significant nuclear morphological changes, including chromatin condensation, formation of apoptotic bodies, and wrinkling of the cell membrane.
Conclusions: The combined application of harmine and a low-frequency electromagnetic field induced apoptosis in A2780 cancer cells and resulted in the downregulation of COX2, VEGF-A, and MMP-2 gene expression. Consequently, the combined use of harmine with a low-frequency electromagnetic field, due to its effective cytotoxicity in inhibiting proliferation and inducing apoptosis, could be a suitable candidate for clinical studies.

Abstract
Introduction: The thickness of the molecular and pyramidal layers in the hippocampus represents a pivotal aspect of Alzheimer's research. This study was conducted to investigate the effect of swimming endurance, resistance, and combined exercises on the molecular and pyramidal layers of the hippocampus tissue thickness of Alzheimer's rats.
Methods: In this experimental study, 40 large white Wistar laboratory rats (6 weeks old; Weight 180-200 g) were randomly and equally divided into five groups: healthy control, Alzheimer's control, endurance, resistance, and combined. Alzheimer's disease was induced by intraperitoneal injection of trimethyltin chloride (8 mg/kg). Two weeks after the injection and confirmation of Alzheimer's induction, the training protocols of endurance (5-sessions/week, the first to the fourth week incrementally from 5-15-min to 45-min of swimming, the fifth to the twelfth week 60-min of swimming), resistance (5-sessions/week, The first week of familiarization with the exercise, week 2; 30%, week3-5; 70-90%, week6-8; 100-110%, week9-10; 120-130%, and week11-12; 140-150% of body weight), combined (2 resistance sessions/week and three endurance sessions/week) was performed for 12 weeks. Forty-eight hours post-intervention, animals were dissected, and hippocampus tissue was harvested. Finally, the data were analyzed at the significance level of P < 0.05.
Results: The thickness of the molecular and pyramidal layers of the hippocampal tissue of Alzheimer's animals decreased compared to healthy animals, and all three endurance, resistance, and combined exercise protocols increased layers (P < 0.001). However, the increase in the molecular and pyramidal layers thickness of the hippocampal tissue of combined group rats compared to the endurance and resistance group had a greater increase (P < 0.01).
Conclusions: These findings highlight the changes in the thickness of the hippocampal tissue layers concerning Alzheimer's pathology and the effect of combined exercises on this parameter. While exercise may have positively affected hippocampal volume and synaptic plasticity, more research is needed to fully understand the impact of exercise on hippocampal layer thickness in Alzheimer's.

Introduction: Glyphosate is the most popular broad-spectrum herbicide globally due to the growing demand for glyphosate-resistant crops. Glyphosate exhibits harmful properties, including cytotoxicity, neurotoxicity, and reproductive toxicity. This study aimed to investigate the detrimental effects of glyphosate on ovarian histopathology in mice and the in vitro maturation (IVM) of oocytes following superovulation.
Methods: In this study, thirty-two female NMRI mice were randomly divided into the following groups: control, glyphosate, superovulation, and superovulation-glyphosate. Animals received glyphosate (0.5%) continuously through drinking water for three weeks. HMG and HCG were used to induce superovulation. Oocytes were collected from the ampulla, and the quantity and quality of oocytes were analyzed. Then, in vitro maturation (IVM) of oocytes was performed. At the end of the study, ovarian histopathology was analyzed.
Results: Compared to the control group, the glyphosate-treated group exhibited a significant decrease in secondary and Graafian follicles while demonstrating a concomitant increase in atretic follicles (P < 0.05). Additionally, the superovulation-glyphosate group showed fewer germinal vesicle breakdown (GVBD) and MII oocytes than the superovulation group. In the superovulation-glyphosate group, there was a notable reduction in GVBD and MII oocytes following in vitro maturation (IVM).
Conclusions: Glyphosate has the potential to damage ovarian tissue and adversely affect IVM and oogenesis.

Abstract
Introduction: Dermatoglyphic is a science that study the lines in the skin of the palms and fingertips properly. In some studies, the relationship between dermatoglyphic patterns with some diseases has been proven Arthritis Rheumatoid is a chronic inflammatory disease with autoimmune pathogenesis. The aim of this study was to investigate the qualitative and quantitative characteristics of dermatoglyphics in people with rheumatoid arthritis compared to the control group.
Methods: This case-control study was conducted on 50 patients with rheumatoid arthritis and 50 people in the control group living in Mashhad. The fingerprint was recorded by the scanner. The distribution of the frequency of fingerprint patterns, including Arch, Loop and Whorl, along with the counting of fingerprint lines in both groups was investigated. Finally, the obtained data were analyzed using ANOVA and X2 tests.
Results: According to the results, the maximum frequency of dermatoglyphic patterns in both hands was related to the ulnar loop type. After that, in the patient group, simple Whorl patterns and double Whorl patterns and in the healthy group, double Whorl patterns and simple Whorl patterns were the most frequent. Between the average finger ridge count in the right hand of healthy people with the right hand of patient’s people and the left hand of healthy people with the left hand of patient’s people showed a significant difference in the error level of 0.05.
Conclusions: It seems that this difference can be used as a biological diagnostic marker to screen people prone to rheumatoid arthritis. This information in prognosis of psychological, medical and therapeutic plans, issues related to anthropology and social sciences can also be useful.
