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.

Background: Multiple sclerosis (MS) is a demyelination disorder of the central nervous system (CNS), which is believed to be associated with oxidative stress. Therefore, researchers try to find reliable biomarkers to monitor the disease and predict its prognosis. Cholesterol and lipids in the myelin sheath are vital for nerve cells. Serum low-density lipoprotein (LDL) is susceptible to lipid peroxidation induced by oxidative stress. This study aimed to evaluate oxidative stress markers in the serum of patients with relapsing-remitting MS (RRMS) and examine their correlation with lipid markers.
Methods: A total of 18 MS patients (14 women and 4 men) and 18 healthy subjects (matched by age and sex) were enrolled in this cross-sectional study. The serum samples were collected in both relapsing and remitting phases. The prooxidant-antioxidant balance (PAB), malondialdehyde (MDA), and oxidized LDL (oxLDL) were measured as markers of oxidative stress.
Results: The mean age of participants was 29.21 (22-42) years. In the comparison between the patient and control groups, the most differences were increased levels of PAB in the patient group (P < 0.05), no difference between relapsing and remitting phases (P = 0.995), increased MDA levels in the relapsing phase (P = 0.013)––but no change in the remitting phase (P = 0.068), no difference in LDL and oxLDL levels in the patient group (P > 0.05), and MDA, LDL, and oxLDL levels did not have any significant correlation with PAB (P > 0.05).
Conclusion: High levels of oxidative stress markers were present in both phases of the disease. Lipid peroxidation markers (such as MDA) increased in the acute phase, but oxLDL did not change. Also, there was no significant correlation between oxidative stress and cholesterol markers.

Abstract
Background: Medicinal plants have played crucial roles in the traditional health care system since the origin of mankind. Among them, cinnamon is used not only as a spice in food but also as a substance with many health-beneficial effects. The aim of the present study was to identify the antibacterial activity of cinnamon bark extract against bacterial isolates from patient pus samples that might help treat infections.
Methods: The antibacterial potential of cinnamon bark extract in both ethanol and methanol against 6 bacterial isolates obtained from pus samples received in the Microbiology Laboratory was identified by agar well diffusion, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) using standard techniques.
Results: By agar well diffusion, the highest inhibitory activity of ethanol and methanol extracts of cinnamon was shown by Staphylococcus aureus, followed by coagulase-negative Staphylococci. The lowest inhibitory effect was shown by Proteus mirabilis. The ethanol extract of cinnamon MIC and MBC ranged from 6.25 mg/mL to 12.5 mg/mL and 12.5 mg/mL to 50 mg/mL. The methanol extract of cinnamon MIC showed a value of 12.5 mg/mL, and the methanol extract of MBC ranged from 12.5 mg/mL to 50 mg/mL against all bacterial isolates of the present study.
Conclusion: Staphylococcus aureus is sensitive to the alcoholic extract of cinnamon bark, but its effect is less than that of the selected antibiotic.

Abstract
Background: Recently, a rare heterozygous DYRK1B mutation (R102C) has been shown to be completely associated with a familial form of metabolic syndrome. The present study was done to create the R102C mutation in the mouse DYRK1B gene, produce recombinant lentiviruses and infect target cells with these viruses as a strategy for long-term gene expression.
Materials & methods: The DYRK1B mutation (R102C) gene created by Overlap Extension-PCR (OE-PCR) was cloned into the LeGO-iG2 transfer vector containing the GFP marker. To produce recombinant lentiviruses, the transfer vector carrying DYRK1B R102C and psPAX2 (packaging vector), and pMD2 (envelope vector) were simultaneously transferred into HEK-293T cells.
Results: OE-PCR method and sequencing showed that carried out the intended mutation was correct. Also, to observe the DYRK1B expression, which shows gene transfer success, a fluorescence microscope was used to check the GFP marker. Flow cytometry technique was used to determine the lentiviral titer. The infection efficiency of HEK-293T cells with lentivirus was (108 TU/ml).
Conclusion: DYRK1B contributes to the development of metabolic syndrome, central obesity, early-onset coronary artery disease, hypertension, type 2 diabetes, and adipogenesis; thus, Therefore, curiosity about this gene can be effective in the development of therapeutic agents against these diseases. Lentiviruses containing DYRK1B R102C mutation have many benefits for in-vitro and in-vivo metabolic syndrome research. This study shows the successful use of recombinant lentiviral vectors for transferring genes into eukaryotic cells.
