Also, Coumarins have high ability to control and treat cancer. Apoptosis is a planned cell death that plays an essential role in the development and homostasis of living creatures. Bax and Bcl2 genes are among key target genes of internal pathway; thus the present study aimed to determine the effect of L. reuteri and Coumarin on the expression of these two genes on AGS cell line. Materials and Methods: After cultivation of gastric cancer cells, Coumarin and L. reuteri were affected in these concentrations at different concentrations and the inhibitory effect on cell proliferation was evaluated using the MTT method. Afterwards, the RNA content of cells was extracted using an RNA extraction kit. Then the cDNA was synthesized for Bax and Bcl2 genes and finally Real time PCR was run. Results: The results of the MTT assay on gastric cancer cells showed the inhibitory effect of Coumarin and L. reuteri. Also, the results of Real Time PCR showed that the expression of Bax and Bcl2 expression in comparison with the control group was significantly increased. Conclusion: Considering the effects of Coumarin and L. reuteri on inhibiting proliferation of AGS cells and increasing the Bax and Bcl2 gene, it can be concluded that Coumarin and L. reuteri can induce apoptosis in cancerous cells by affecting the expression of genes involved in apoptosis.}, Keywords = {Stomach cancer, Lactobacillus reuteri, Coumarin}, volume = {24}, Number = {2}, pages = {122-132}, publisher = {Kashan University of Medical Sciences}, url = {http://feyz.kaums.ac.ir/article-1-3934-en.html}, eprint = {http://feyz.kaums.ac.ir/article-1-3934-en.pdf}, journal = {Feyz Medical Sciences Journal}, issn = {1029-7855}, eissn = {2008-9821}, year = {2020} } @article{ author = {Behjati-Moghaddam, Mahsa and Neamati, Ali and Yousefirad, Hadiseh}, title = {Evaluation of antioxidant, antibacterial and anticancer effects of the Zinc oxide nanoparticles biosynthesized by Amaranthus cruentus L.}, abstract ={Background: Nanoparticles are effective in treating the cancer disease due to their antioxidant, Antibacterial and the ability to produce toxicity in the cancer cells. This study aimed to evaluation of cytotoxic, antioxidant and antibacterial effects of zinc oxide nanoparticles synthesized by Amaranthus cruentus. Materials and Methods: This study was performed in vitro. The cytotoxic effects of biosynthesized ZnO nanoparticles were evaluated against the cancer cell line MDA-MB-231 and the normal cell line HUVEC by MTT assay. Also, antioxidant properties of these nanoparticles were evaluated by assays the DPPH and ABTS. Statistical analysis was performed by SPSS software and one way ANOVA. Antibacterial activity was also evaluated by the disc diffusion method on the gram-positive bacteria Staphylococcus aureus and gram-negative Pseudomonas aeruginosa. Results: The result of MTT assay showed that IC50 was about 32µg/ml in 48 hours after treatment of the breast cancer cells by nanoparticles while the viability of the normal cell line was 94% in the similar concentration of nanoparticles. The results of the antioxidant test showed that nanoparticles at a concentration of 1000µg/ml were able to inhibit 50% of ABTS free radicals, but they exhibited a slight potential for DPPH free radicals inhibition.

This study aimed to determine the effect of the continuous aerobic - versus high -intensity interval training on IRS1 gene expression and its correlation with insulin resistance index in liver tissue with type 2 diabetic rats. Materials and Methods: In an experimental study, 24 male Wistar rats aged 6-5 weeks weighed 160 to 180 g. The rats were randomly divided into three groups of 8 controls, aerobic continuity, and severe periodicity. Each group performed their protocol five days a week for eight weeks. 24 hours after the last training session, blood samples were collected directly from heart of rats. The liver tissue was immediately extracted. Pearson correlation, one-way ANOVA and Tukey post hoc test were used to analyze the data. Results: The results of this research showed that both trainings had a significant effect on the expression of IRS1 gene in the liver of type 2 diabetes mellitus than in the control group (P=0.011), but no difference was observed in the two training groups (P=0.874). There was a significant correlation between IRS1 gene expression and insulin resistance index in the liver of type 2 diabetic rats after a HIIT and continuous exercise (P=-0.634).

After diabetic induction with STZ and Nicotinamide, rats were randomly assigned to two groups, diabetic training (6 heads) and diabetic control (6 heads). The training group trained for 4 days a week in accordance with the training program for 4 weeks, while the control group did not have any training program. Also, the rats did not receive any insulin treatment during the study period. The protein content of the present study was measured by Western blotting. Data were analyzed by SPSS software version 19 and independent t-test. Results: Four weeks of HIIT training resulted in a significant decrease in FOXO3a (P=0.03) and Beclin-1 (P=0.0001) proteins content in the diabetic training group compared to the diabetic control group.

Therefore, the purpose of this study was to investigate the effect of 6 weeks of high intensity interval training (HIIT) with nano-curcumin supplementation on factors related to cardiovascular disease such as lipid profile and C-reactive protein (hs-CRP) in overweight girls. Materials and Methods: The research method was randomized-experimental with pre-post test design. 48 overweight student girls with mean age of 21.78±0.94 years and BMI equals 28.12±2.1kg/m2 were randomly divided into four groups: training (n=12), training-supplement (n=12), supplement (n=12) and control group (n=12). Supplement groups consumed a 80 mg nano-curcumin capsule daily. Training groups performed an exercise protocol of HIIT training with maximum heart rate for 6 weeks (three sessions per week). The control group did not have any regular exercise. Blood samples were obtained for measurement of lipid profile serum levels (Low Density Lipoprotein (LDL), Total Cholesterol (TC), Triglyceride (TG) and High-Density Lipoprotein (HDL)) and CRP before and after a 6-week period of exercise and supplementation. Data were analyzed by ANOVA and dependent t-test at P≤0.05. Results: In the supplement-training group, triglyceride (P=0.03) and CRP (P=0.03) significantly decreased, HDL (P=0.034) significantly increased and LDL and cholesterol did not show significant changes (P≥0.05). But there were no significant changes in lipid profile and CRP in the training and supplement groups (P≥0.05).
