The aims of this study were biosynthesis of silver nanoparticles using different tree gum extracts and evaluation of the toxicity of nanoparticles and their salts against two bacteria: Escherichia coli and Staphylococcus aureus.   Materials & Methods: In this study, silver nanoparticles (SNPs) synthesized from manna of Quercus, Cerasus avium, and Prunus armeniaca gum extracts were investigated for their antibacterial activity. Silver nanoparticles were prepared from the reduction of silver nitrate. Copper nanoparticles (CuNPs) were formed by reduction of CuCl2 with L-ascorbic acid. Prepared nanoparticles were characterized by ultraviolet-visible spectroscopy and TEM techniques. Antibacterial activities of the nanoparticles were tested against Staphylococcus aureus and Escherichia coli. Findings: In the present study, biosynthesis and characterization of SNPs using Cerasus avium and Prunus armeniaca gum extracts is reported for the first time. The spectrum of the reaction mixture showed a strong absorption peak at 420 nm. TEM image showed that Ag-NPs (SNPs) formed were well dispersed with a spherical structure and 10 to 30 nm particle size range. Bacteria (E. coli and S. aureus) showed clear hypersensitivity to silver and copper nanoparticles, and the effects of SNPs were more notable than those of CuNPs. Data analysis showed that CuCl2 and AgNO3 nanoparticles had a lower inhibitory effect.   Discussion & Conclusions: Our results showed these microorganisms had sensitivity against the tested nanoparticles; however, E. coli showed higher sensitivity than S. aureus to both nanoparticles.     Silver and copper nanoparticles Antibacterial activity Tree gum 2019 3 01 1 9 http://sjimu.medilam.ac.ir/article-1-4264-en.pdf 10.29252/sjimu.26.6.1

Some individual differences, such as sensitivity to noise, can reduce or increase the effect of noise on physiological parameters. The purpose of this study was to investigate the effect of individual sensitivity on physiological parameters in the presence of low-frequency noise.   Materials & Methods: This is an interventional study. 120 subjects were selected through targeted sampling (60 high sensitivity and 60 low sensitivity). By simulating the real environment of each person, they were exposed to 50, 60, and 70 dB of noise. Before and after exposure, the mean body temperature, skin temperature, heart rate, blood pressure, and oxygen content was measured and recorded. Data were analyzed using the SPSS20 software package, independent t-test, and paired T-test. Code of ethics: IR.umsha.REC.1395.457   Findings: The results showed that low-frequency noise negatively affects physiological parameters and increases physiological parameters by increasing the noise level from 50 to 70 dB (P<0.05). Investigating the combined effect of individual sensitivity to noise and gender showed that physiological parameters are more affected in women and people with high sensitivity (P<0.05).   Discussion & Conclusions: Considering that high blood pressure is closely related to cardiovascular disease, the use of people who are more tolerant to noise (low sensitivity) in areas where exposure to noise is higher than the safe limit can prevent cardiac complications.     Low-frequency noise (LFN) Individual sensitivity noise Physiological parameter 2019 3 01 10 22 http://sjimu.medilam.ac.ir/article-1-4526-en.pdf 10.29252/sjimu.26.6.10

Instructional strategies with an internal focus of attention have traditionally been utilized, but may not be optimal for the acquisition of the control of complex motor skills. Conversely, external-focus instructional strategies may enhance skill acquisition more efficiently and increase the transfer of improved motor skills to sports activities Objective: The purpose of the current study was investigation of the effect of feedback training utilizing external focus of attention on kinetic, kinematic, and functional factors of active subjects. Materials and Methods: Twenty-four males (aged 24.83±2.77 years, BMI 22.20±1.8 kg/m2, and weight 72.20±9.30 kg) were randomly assigned to feedback (n=12) and control (n=12) groups. The Feedback group completed training 3 times a week for 8 weeks; training lasted 45 min in each session. Peak knee flexion angle was measured using 3D motion analysis during landing, peak vertical and posterior ground reaction force was measured using force plate set, and functional movement was measured using triple hop test. For data analysis repeated measures analysis of variance, independent-sample, and paired t tests were used. Findings:  Results revealed that feedback training caused significantly increased peak knee flexion angle (p=0.001, pre=44.88±4.89, post=51.26±4.80, effect size=1.266), increased functional movement of subjects (p=0.006, pre=5.11±.51, post=5.21±.49, effect size=0.911), and decreased peek posterior ground reaction force (p=0.011, pre=-303±55.39, post=-271±45.83, effect size=0.877). There was no significant effect in peak vertical ground reaction force (p=0.134, pre=2076±426.79, post=1884±328.18, effect size=0.612 ). Conclusion: Given the reported significant effect of training on peak hip abduction moment and functional movement of participants, coaches and athletes recommended that to reduce the risk factors associated with anterior cruciate ligament injury and increase athletic functional performance, feedback training should be used during training sessions.

The purpose of this study was to investigate the effects of resistance training on GLUT4 gene expression and glycemic index in rats with type 2 diabetes. Materials & Methods: Twenty-seven Wistar rats were selected; the rats were fed a high-fat diet for 6 weeks and then randomly divided into three groups: diabetic with resistance training (n=10), diabetic control (n=10), and obesity control (n=7). Type 2 diabetes was induced by injection of a low dose of Streptozotocin (STZ) (30 mg/kg). The resistance training program was performed for 6 weeks, five days per week. The glucose concentration was measured by glucose oxidase enzyme technology, serum insulin by the ELISA method, and real-time PCR was used to test the GLUT4 gene expression. For data analysis, independent t-test and one-way analysis of variance were used (α=0/ 05). Findings: The results indicated that induction of diabetes reduced the GLUT4 gene expression in the gastrocnemius muscle tissue of diabetic rats (P=0.001). Also, GLUT4 gene expression increased in the diabetic training group compared with the diabetic control group (P=0.038). In addition, blood glucose and insulin resistance decreased significantly. The content of GLUT4 gene expression was increased in the training group compared with the diabetic control group (p=0.001). Discussion & Conclusions: Based on the findings of this study, it can be stated that the GLUT4 gene expression in rat gastrocnemius muscle tissue is reduced in diabetic rats. Also, resistance training could increase the GLUT4 gene expression and improve glucose transport and insulin resistance in type 2 diabetic rats. This could be due to improvement in the performance of glucose transporters by resistance training.

It is often diagnosed at advanced stages. One of the mechanisms of the immune system to fight lung cancer cells is autophagy. Autophagy is a conserved catabolic process in which proteins and organelles are deleted by lysosomes. microRNAs are small RNAs containing about 19–22 nucleotides that function as important regulatory elements in the cell and as oncogene or tumor suppressors in lung cancer. The role of miRNAs is important in lung cancer progression by regulating autophagy genes of several proteins. The aim of this study was to evaluate the expression of miR-204-5p and miR-20a expressions involved in the autophagy pathway in non-small cell lung cancer.   Materials & Methods: In this study, miR-204-5p and miR-20a expression levels were studied, using the quantitative Real-Time PCR technique, in 30 patients with non-small cell lung cancer. RNA was extracted from tumor and adjacent normal tissue of NSCLC patients. cDNA was synthesized using specific stem-loop for miR-20a, miR-204-5p, and RNU44 reference gene. Finally, the expression levels of miRNAs were assessed by Real-Time PCR and the data were analyzed using the 2-∆∆CT method. Code of ethics: sbmub.REC.1394.112   Findings: Based on the results of the qRT-PCR analysis it was revealed that miR-20a and miR-204 were upregulated and downregulated in tumor tissues, respectively.   Discussion & Conclusions: These changes in the expression level, suggest that miR-20a and miR-204-5p are oncogenes and tumor suppressors, respectively. So, measuring the expression level of miR-20a could be a biomarker for the diagnosis and progression of non-small cell lung cancer as well as a platform for the targeted treatment of cancer.     MicroRNA Autophagy Lung cancer Biomarker 2019 3 01 58 68 http://sjimu.medilam.ac.ir/article-1-4481-en.pdf 10.29252/sjimu.26.6.58

Testicular heat-stress even for a single short period can induce destruction in testicular tissue and spermatogenesis disturbances. This study was conducted to determine the protective effects of royal jelly (RJ) against testicular damage and spermatogenesis following heat-stress induction in male rats.   Materials & Methods: In this experimental study, 48 male rats were randomly divided into 8 groups (n=6( including: 1- Control, 2- RJ (100 mg/kg BW/day; PO), 3 , 4 and 5 heat-stressed  (43, 39, and 37 for 20 min per day, respectively) and 6, 7 and 8 heat-stressed along with RJ (43, 39, and 37 for 20 min per day, respectively plus RJ at a dose of 100 mg/kg BW/day; PO). Heat-stress was induced through immersion of experimental rat scrotums in a water bath. After 48 days, the animals were sacrificed and left testes were removed and fixed. Five-micrometer testicular tissue sections were prepared and studied using a light microscope.   Findings: The data revealed that diameter and germinal epithelium height of the seminiferous tubules, thickness of basement membrane, number of spermatogenic and Sertoli cells, and testicular weight decreased significantly (p<0.05) in heat-stress groups compared to control and RJ groups. Interestingly, RJ co-administration significantly (p<0.05) ameliorated above-noted parameters in all heat-stress-exposed animals except in 43  heat-stress + RJ group.   Discussion & Conclusions: RJ administration can protect testicular tissue changes and prevent reduction of spermatogenic cell counts in testicular heat stress conditions.   Heat Stress Royal Jelly Spermatogenesis Testis Rat 2019 3 01 69 78 http://sjimu.medilam.ac.ir/article-1-4554-en.pdf 10.29252/sjimu.26.6.69

Extraction method is effective on the percentage and type of chemical compounds present in the extract. The aim of this study was phytochemical surveying of turmeric soxhelt extract by using instrumental analysis and determination of flavonoids and flavenols contents in different extraction methods. Materials & Methods: Phytochemical tests were done on ethanolic soxhelt extract to determine secondary metabolites and different instrumental analysis methods in order to verify the existence of curcuminoids on it extract took place. The content of flavonoids and flavonol extracts were measured by different extraction methods (maceration, ultrasonic and soxhlet) using quercetin as a standard. Findings: The results of phytochemical studies have confirmed the presence of alkaloid, flavonoids and glycosides compounds and the absence of tannins and saponins in the ethanolic soxhelt extract. The results of IR, UV, GC and GC / Mass indicate the presence of curcuminoids in turmeric extract by soxhelt extraction. The results of statistical tests indicated that the highest content of flavonoids and flavenols belongs to the extraction with hexane and ethanol. Discussion & Conclusion: In soxhelt method despite requiring high temperature and using of hot solvent, the curcuminoids structure was retained and this extraction method may be a suitable method for curcumin extraction from turmeric plant. Also suitable method for extracting flavonoids and flavonoid compounds is extraction with two solvent “ethanol and hexane“.

Ergosterol is the main component of the fungal cell membrane. Inhibition of the 14α-demethylase enzyme will result in decreased ergosterol synthesis. Ergosterol plays a hormone-like role in fungal cells, which stimulates growth. The net effect of azoles is inhibition of fungal growth. In this research, a group of azole derivatives with CYP51 inhibitory activity was subjected to a docking study, followed by toxicity risk assessment.   Materials & Methods: This research is a descriptive-analytic study. In order to investigate the mode of the benzimidazole oxime ether derivatives coupling with the enzyme active site, at first, the chemical structures of all compounds were designed using the ChemBioDraw Ultra14.0 software. Then to maximize energy efficiency, they were exported into the HyperChem software package. Docking study was performed using the Auto Dock Vina program. Then the results were analyzed utilizing the Molegro Virtual Docking software. At the final stage, the toxicity risk assessment of compounds was performed using the OSIRIS program.   Findings: According to docking study results, the main bonds in drug-receptor interactions are azole-heme coordination, the hydrogen bond, and hydrophobic interactions. Among all studied compounds, the best docking results are related to combination No.1 (imidazole heterocycle-pathic compound). In fact, this compound had the most negative ΔGbind (-9.17 Kcal/mol), which indicated favorable interactions with the key amino acid residues at the active site of CYP51.   Discussion & conclusions: According to the results of docking studies and the evaluation of toxicity risk, it can be concluded that combination No. 1(imidazole heterocycle-pathic compound) in comparison with fluconazole reference compound might be considered a more effective inhibitor of the CYP51 enzyme.

The BLF1 protein of Burkholderia pseudomallei bacteria plays an important role in pathogenesis and infection. Shigella dysentery STxB is one of the most important factors in pathogenesis and also has an adjuvant role. Binding the BLF1 protein with STxB can be a good candidate vaccine. In this study, the antibody titers of BLF1-STxB and BLF1 proteins produced in rats were compared.    Materials & Methods: In this experimental study, pET28a (+) - blf1-stxB and pET28a (+) - blf1 vectors were transformed into E. coli BL21 (DE3) and confirmed by PCR. The expression of blf1-stxB and blf1 genes was induced by IPTG and the proteins were injected into rats four times after purification of the protein by using an affinity chromatography column. Polyclonal antibodies produced in the serum of rats were measured.   The produced recombinant proteins were approved by SDS-PAGE and Western blotting. ELISA results showed that antibody was produced against the BLF1 antigen and the antibody titer level increased by STxB binding to BLF1, compared with the antibody titer against the BLF1 antigen.   Discussion & Conclusions: The BLF1-STxB protein had higher antibody titer than BLF1. Due to the structural similarity of STxB subunit with its counterpart in E. coli, it can be a vaccine candidate against Burkholderia pseudomallei, Shigella dysenteriae, enterohemorrhagic E. coli, and enterotoxigenic E. coli.   Burkholderia pseudomallei Shigella dysenteriae Melioidosis BLF1 STxB 2019 3 01 111 121 http://sjimu.medilam.ac.ir/article-1-4462-en.pdf 10.29252/sjimu.26.6.111

Studies have shown that silver nanoparticles have cytotoxic effects on the growth of cancerous cells. On the other hand, the antioxidant properties of this nanoparticle have been proven in many studies. Therefore, in this investigation, antioxidant capacity and cytotoxicity effects of silver nanoparticles synthesized from Root of Persicaria bistorta L (Bi/Ag-NPs) on liver cancer cells (HepG2) compared with normal skin cells (HDF) were studied. In addition, ABTS and DPPH free radical scavenging capacity of Bi/Ag-NPs was evaluated using colorimetric tests.   Materials & Methods: In order to evaluate the cytotoxicity effects, first the cancerous and normal cells were cultured and treated with various concentrations of Bi/Ag-NPs and finally, the cell survival rate was estimated using the MTT assay. The antioxidant activity of Bi/Ag-NPs was evaluated according to the amount of ABTS and DPPH free radicals inhibition.   Findings:  The results showed that Bi/Ag-NPs inhibited cancer cells with an IC50 value of about 3 μg/ml, while at this concentration they were ineffective on normal cells (IC50: 50 μg/ml). The scavenging of ABTS (IC50: 15 μg / ml) and DPPH (IC50: 20 μg/ml) free radicals confirmed the antioxidant properties of Bi/Ag-NPs.   Discussion & Conclusions: The cytotoxic and antioxidant results show that Bi/Ag-NPs can be used as auxiliary agents for treating many diseases that are caused by oxidative stress and other biomedical applications.     Antioxidant Silver nanoparticles Persicaria bistorta Cancer 2019 3 01 133 142 http://sjimu.medilam.ac.ir/article-1-4671-en.pdf 10.29252/sjimu.26.6.133

Due to the significant role of enhanced oxidative stress in the development of ovarian damage in diabetics, this study was conducted to evaluate the effect of chronic administration of zinc sulfate on oxidative stress markers in ovarian tissue of diabetic rats.   Materials & Methods: This experimental study was performed on 24 female Wistar rats weighing 120 -150 gr. The rats were divided into four groups: normal control (NC), diabetic control (DC), and two diabetic groups treated with zinc sulfate (15 and 30 mg/kg). Zinc sulfate was administered one week after streptozotocin injection for 28 days (via gavage daily). At the end of the experiment, the body weight and blood sugar of the animals were measured and compared with the weight and blood glucose measured in the week before the study. Also malondialdehyde levels (MDA), catalase activity (CAT), and total antioxidant capacity (TAC) as oxidative stress indices in ovarian tissue were measured. In the end, the data were analyzed statistically using the SPSS software, and ANOVA and Tukey’s tests were analyzed.   Findings: Chronic uncontrolled Hyperglycemia (blood glucose greater than 300 mg/dl) significantly increased the levels of MDA in diabetic animals compared to normal animals (p<0.05). Also, hyperglycemia caused a decrease in the activity of the catalase enzyme and the levels of total antioxidant capacity (TAC) in diabetic animals (p<0/05). and Hyperglycemia reduced the activity of the catalase enzyme and ultimately the capacity The total antioxidant of the total antioxidant (TAC) of diabetic animals (p<0/05). Administration of zinc sulfate by increasing the activity of the catalase enzyme reduced the levels of MDA in diabetic animal ovary tissue in comparison with the diabetic control group, but could not significantly affect TAC.   Discussion & Conclusions: Administration of zinc sulfate for four weeks in a dose-dependent manner reduces oxidative stress indexes in ovarian tissue of diabetic rats.     Zinc sulfate Diabetes mellitus Oxidative stress Ovary Rat 2019 3 01 164 175 http://sjimu.medilam.ac.ir/article-1-4613-en.pdf 10.29252/sjimu.26.6.164

Previous studies addressed different types of drugs, such as anti-seizure drugs and anti-psychotics. This study aimed to investigate the effects of ketorolac on tolerance and dependence to the analgesic properties of the chronic use of morphine in male mice.   Materials & Methods: In this study, adult male albino mice were divided into 9 groups. In order to investigate the analgesic tolerance, mice received morphine plus ketorolac either on 5 consecutive days or a single dose in the fifth day. The hot plate test was performed and latency times were recorded. For the evaluation of chemical pain, formalin subplantar injection was administered and the pain marks were recorded. Finally, dependence assessment was performed using naloxone hydrochloride injection on the fifth day, and the withdrawal symptoms were recorded.   Findings: There was a significant difference (P<0.05) among the single dose of morphine, normal saline (as the negative control group), and chronic morphine administration; with no significant difference between taking a single dose of morphine or ketorolac in the addicted mice. Regarding the dependence, there was a significant difference (P<0.05) between the chronic use of morphine and chronic morphine plus ketorolac administration were reported.   Discussion & Conclusions: It can be concluded that ketorolac have an anti-analgesic effect on chemical pain. It reduces tolerance to morphine anti-analgesic effect and it is capable of reducing the withdrawal syndrome symptoms induced by naloxone.   Morphine Ketorolac Tolerance Dependence 2019 3 01 183 193 http://sjimu.medilam.ac.ir/article-1-5112-en.pdf 10.29252/sjimu.26.6.183

Meanwhile, one of the concepts that attracted the attention of organizational experts is workplace incivility. The purpose of this study was to determine the effect of workplace incivility on the unproductive behaviors of hospital staff. Accordingly, the present study sought to reduce the scientific gap between the processes of workplace incivility behavior and to help managers avoid such behaviors, thereby enhancing citizenship behaviors, improving the efficiency and effectiveness of the organization and avoid the direct and indirect devastating effects of this phenomenon on the organization.   Materials & Methods: This descriptive-correlational study was conducted on 344 employees of hospitals in Khorramabad, Lorestan, Iran, in 2017.  The participants were selected from the study population of 3224 employees using simple random sampling technique. The study instruments were workplace Incivility Behavior, Self-monitoring, Locus of Control, Compulsory Citizenship Behavior, Anti-Citizenship Behavior, and Counterproductive workplace behavior scales whose validity and validity was confirmed by Cronbach's alpha and content validity. The data were analyzed using PLS software and tested by structural equation method (SEM) in terms of confirmatory factor analysis and hypothesis testing parts.   Findings: The results of the research show that workplace incivility behaviors affect the non-productive behaviors of the staff positively and significantly (t>1.96). In this regard, the variables of Compulsory Citizenship Behavior and anti-citizen behavior play a mediating role (t>1.96). Moreover, the moderating role of locus of control and self-monitoring was negatively significant (t>1.96; β<0).   Discussion & Conclusions: Considering the destructive effects of incivility on the organization, it is necessary to consider transparent and precise management measures, improvement of the working environment, and the necessary training regarding hospital staff behavior.

Oxidative stress and subsequent apoptosis are recognized as factors involved in the pathogenesis of MS.  On the other hand, 17-β-estradiol is well known  for its anti-oxidant properties. Therefore, this study aimed to investigate the effect of 17-beta-estradiol on oxidative stress parameters in the experimental model of MS.   Materials & Methods: This study was conducted on 49 Wistar male rats cannulating into the CA1 area of hippocampus. The rats were randomly divided into following groups (n=7): control group, sham group, MS group, estradiol groups, MS+estradiol groups. MS model was induced by intrahippocampal injection of ethidium bromide and estradiol was injected as a pretreatment for 5 days. At the end of experiments, the levels of oxidative stress parameters, such as MDA, Glutathione, and antioxidant enzymes (Glutathione peroxidase, Superoxide dismutase and Catalase)were measured in this study.   Findings: The microinjection of ethidium bromide increased the oxidative capacity and reduced the antioxidant enzyme (SOD GPx and CAT) activity (P<0.05). The pre-treatment of 17-beta-estradiol prevented an increase in oxidative capacity and decreased the activity of antioxidant enzymes in the experimental groups (P<0.05).   Discussion & Conclu sions: The 17-beta-estradiol, as a potent antioxidant, is likely to prevent the increase of oxidative stress indices in the experimental model of MS by removing reactive oxygen species and clearing the tissues from free radicals.
