The present study examined effect of 12 weeks of aerobic interval training on HDL-associated APOM levels.              Methods: Study population included 20 healthy men aged 20 to 24 years. The subjects were randomly and equally divided into a training group and a control group. Each training session included 10 minutes of warm-up, 35 minutes of aerobic training (5 combined cycles each including four minutes of running at intensity of 85-95% and an active resting period of treadmill running at 65-75% of maximum heart rate for 3 minutes) and 10 minutes of cool-down. Blood samples (10 mL) were taken every four weeks. Two-way ANOVA and Bonferroni's post hoc test were used to compare the groups. A P-value of less than 0.05 was considered statistically significant.              Results: At the end of the 12th week, HDL-associated APOM levels increased in the training group and decreased in the control group. However, these changes were not statistically significant (P>0.05).               Conclusion: This study demonstrated that the 12-week aerobic interval training does not significantly affect HDL-associated APOM levels. However, it is recommended to monitor subjects’ diet throughout the study period to reach a more comprehensive conclusion.               Keywords: Aerobic interval training, Apolipoprotein M, Young men.}, Keywords = {Aerobic interval training, Apolipoprotein M, Young men.}, volume = {13}, Number = {3}, pages = {1-5}, publisher = {school of paramedicine, golestan university of medical sciences}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, doi = {10.29252/mlj.13.3.1}, url = {http://mlj.goums.ac.ir/article-1-1195-en.html}, eprint = {http://mlj.goums.ac.ir/article-1-1195-en.pdf}, journal = {Medical Laboratory Journal}, issn = {}, eissn = {2538-4449}, year = {2019} } @article{ author = {Ebrahimi, Azizollah and Babaaie, Azimeh and Boniadian, Mojtaba and Lotfalian, Sharareh}, title = {Antibacterial and Ciprofloxacin-Potentiation Activities of Cinnamomum zeylanicum Extracts against Some Pathogenic Bacteria}, abstract ={ABSTRACT              Background and Objectives: Efflux-based systems may play a role in resistance to fluoroquinolones in Gram-negative pathogenic bacteria.

We also analyzed the extracts for presence of efflux pump inhibitors against the examined bacteria.              Methods:  Powdered dried leaves and branches of C. zeylanicum were extracted with ethanol (85%) and chloroform by the maceration method. Minimum inhibitory concentrations of the extracts alone or combined with ciprofloxacin and phenylalanine-arginine β-naphthylamide (an efflux pump inhibitor) were determined against Pseudomonas aeruginosa, Acinetobacter bummani, Escherichia coli and Salmonella enteritidis using the double serial microdilution method.              Results: The extracts of C. zeylanicum inhibited the growth of all studied bacteria. Synergistic effects were noted between the extracts and ciprofloxacin against all tested bacteria other than P. aeruginosa. Ciprofloxacin efflux pumps in E. coli, S. enteritiditis and A. baumannii were inhibited by the extracts of C. zeylanicum.              Conclusion: The extracts of C. zeylanicum could be used as ciprofloxacin-potentiating agents against some Gram-negative pathogens.              Keywords: Anti-bacterial agents, Cinnamomum zeylanicum, Bacterial pathogens, Efflux pumps.}, Keywords = {Anti-bacterial agents, Cinnamomum zeylanicum, Bacterial pathogens, Efflux pumps.}, volume = {13}, Number = {3}, pages = {6-10}, publisher = {school of paramedicine, golestan university of medical sciences}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, doi = {10.29252/mlj.13.3.6}, url = {http://mlj.goums.ac.ir/article-1-1198-en.html}, eprint = {http://mlj.goums.ac.ir/article-1-1198-en.pdf}, journal = {Medical Laboratory Journal}, issn = {}, eissn = {2538-4449}, year = {2019} } @article{ author = {Hoseinpoor, Hoorieh and Esmaeili, Davou}, title = {Evaluation of Antibacterial Effects of Polyurethane- Cinnamomum zeylanicum Nanofiber Scaffolds against Clinical Isolates of Staphylococcus aureus}, abstract ={ABSTRACT              Background and Objectives: In recent years, infections caused by antibiotic-resistant strains of Staphylococcus aureus have become a major health issue.

Inhibitory activity of the venom against the bacteria was determined by MTT assay and determining minimum inhibitory concentration (MIC).             Results: Results of the MTT assay showed that the crude venom significantly inhibited the growth of E. coli (31.25 and 62.5 ng/mL), S. aureus (at 250 ng/mL) and B. subtilis (at 125 and 250 ng/mL). In the MIC experiment, the crude venom significantly inhibited the growth of E. coli (at concentrations of 31.25 and 62.5ng/mL), S. aureus (at concentrations of 31.25-250 ng/mL) and B. subtilis (at concentrations of 31.25-250ng/mL).             Conclusion: The crude venom of L. dahli and its components showed relatively strong antibacterial effects.             Keywords: Spider venoms, Black Widow Spider, Antibacterial agent, Drug-resistance.}, Keywords = {Spider venoms, Black Widow Spider, Antibacterial agent, Drug-resistance. }, volume = {13}, Number = {3}, pages = {14-19}, publisher = {school of paramedicine, golestan university of medical sciences}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, doi = {10.29252/mlj.13.3.14}, url = {http://mlj.goums.ac.ir/article-1-1201-en.html}, eprint = {http://mlj.goums.ac.ir/article-1-1201-en.pdf}, journal = {Medical Laboratory Journal}, issn = {}, eissn = {2538-4449}, year = {2019} } @article{ author = {Fazel, Farida and Naghibzadeh, Artmis and MohammadRamezanpour, Reza and Bagheri, Reza and Hamidi, Azar and Rashidlamir, Amir}, title = {Effect of Aerobic Exercise with and without Green Coffee Supplementation on Serum Apolipoprotein B and Atherogenic Indices of Overweight Men}, abstract ={  ABSTRACT               Background and Objectives: Coronary heart disease has a direct correlation with plasma levels of Apolipoprotein B (ApoB) and low-density lipoprotein (LDL) and an inverse relationship with high-density lipoprotein (HDL) level. This study aimed at comparing effect of eight weeks of aerobic training with and without green coffee supplementation on serum ApoB level and atherogenic indices of overweight men.               Methods: Thirty overweight men were randomly divided into two groups: training + green coffee supplementation (T+G; n=15) and training + placebo (T+P; n=15). Participants in both groups performed aerobic training, three sessions per week for eight weeks. Initial exercise intensity was set at 50% of maximum heart rate but gradually increased to 75% of maximum heart rate in the last two weeks. In a single-blind design, the subjects in the T+G group received a 400 mg capsule of green coffee bean extract one hour before each exercise session. The T+P group received placebo at the same time. Paired sample t-test and independent t-test were used to compare intra-group and inter-group variations, respectively. All statistical analyses were performed using SPSS (version 22) at significance level of 0.05.               Results: ApoB, LDL/HDL and total cholesterol/HDL decreased significantly in both groups. However, the changes were more notable in the T+G group compared to the T+P group.               Conclusion: The eight-week training program along with green coffee supplementation has positive effects on serum ApoB and atherogenic indices of overweight, inactive men. Therefore, it can be suggested as a non-pharmacological method of preventing cardiovascular disease.               Keywords: Aerobic exercise, green coffee, Overweight, Apolipoprotein b.}, Keywords = {Aerobic exercise, green coffee, Overweight, Apolipoprotein b.}, volume = {13}, Number = {3}, pages = {20-24}, publisher = {school of paramedicine, golestan university of medical sciences}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, doi = {10.29252/mlj.13.3.20}, url = {http://mlj.goums.ac.ir/article-1-1202-en.html}, eprint = {http://mlj.goums.ac.ir/article-1-1202-en.pdf}, journal = {Medical Laboratory Journal}, issn = {}, eissn = {2538-4449}, year = {2019} } @article{ author = {Musavi, Hadis and Fattah, Abolfazl and Abbasi, Mojtab}, title = {Differential Expression of the KLK2 and KLK3 Genes in Peripheral Blood and Tissues Samples of Iranian Patients with Prostate Cancer}, abstract ={ABSTRACT               Background and Objectives: Prostate cancer is a highly prevalent malignancy with a high mortality rate in men. Many studies have investigated the diagnostic value of various genes involved in prostate cancer, but there is no data for Kallikrein 2 (KLK2) and Kallikrein 3 (KLK3) expression patterns among Iranian patients. Therefore, we aimed to evaluate the expression of these two genes in Iranian patients with prostate cancer.               Methods: In this case-control study, three groups consisting of healthy individuals, patients with benign prostatic hyperplasia (BPH) and patients with prostate cancer were studied. Peripheral blood samples were collected from all subjects, mRNA was extracted after cell lysis, and cDNA was synthesized. Real-time PCR was performed to assess gene expression levels relative to a reference gene (18s rRNA gene).               Results: The KLK2 gene was overexpressed in patients with prostate cancer. KLK2 expression differed significantly between the cancer patients and controls. Relative expression of the KLK3 gene in the BPH group was higher than that in the control and cancer groups. However, we observed no significant difference in the expression of KLK3 between the control and cancer subjects.               Conclusion: We demonstrate that analysis of KLK2 expression is a favorable method of diagnosing prostate cancer and discriminating normal individuals from those with BPH or prostate cancer. We also found that the KLK3 gene is highly overexpressed in individuals with BPH, which might indicate that this gene is not cancer-specific.               Keywords: Prostatic Neoplasm, Prostatic Hyperplasia, Kallikreins, Gene Expression.}, Keywords = {Prostatic Neoplasm, Prostatic Hyperplasia, Kallikreins, Gene Expression.}, volume = {13}, Number = {3}, pages = {25-30}, publisher = {school of paramedicine, golestan university of medical sciences}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, doi = {10.29252/mlj.13.3.25}, url = {http://mlj.goums.ac.ir/article-1-1207-en.html}, eprint = {http://mlj.goums.ac.ir/article-1-1207-en.pdf}, journal = {Medical Laboratory Journal}, issn = {}, eissn = {2538-4449}, year = {2019} } @article{ author = {Jomehpour, Najmeh and Ghazvini, Kiarash and Jomehpour, Mahshi}, title = {Antibacterial Activity of Aqueous and Methanolic Extracts of Crocus sativus Stigma and Cinnamomum cassia against Clinical Isolates of some Gram-Positive and Gram-Negative Pathogenic Bacteria}, abstract ={ABSTRACT             Background and Objectives: Medicinal and aromatic plants are sources of natural antimicrobial compounds that could be useful replacements for antibiotics.

Minimal inhibitory concentration (MIC) and minimum bactericidal concentration of each extract against the mentioned bacteria were also determined.             Results: The MIC of the methanolic extract of C. cassia was 80 µg/ml against Enterococcus, K. pneumonia and E. coli. The MIC of the methanolic extract of C. sativus was 160 µg/ml against Enterococcus and S. aureus. The minimum bactericidal concentration of the methanolic extracts of C. sativus and C. cassia was 320 µg/ml against K. pneumonia and 160 µg/ml against Enterococcus.             Conclusion: The extracts of C. sativus and C. cassia exhibit promising antibacterial activities against clinical isolates of the tested bacteria.
