Abstract

Peripheral blood mononuclear cells are a potential source of cells to be induced into pluripotent stem cells because the collection procedure is easy, minimally invasive, and can be stored in a frozen form. Small molecule compound VC6TFZ consisting of valproic acid (VPA), CHIR990210 (CHIR), 616452, Tranylcypromine, Farsokline, 3-deazaneplanocin (DZnep) and TTNPB has been shown to induce pluripotency in mouse fibroblasts, but this has not been proven in peripheral blood cells. This chemical reprogramming strategy has the potential to be used in producing the desired functional cell types for clinical applications. This study aims to determine whether the small molecule compound VC6TFZ can induce pluripotency of peripheral blood mononuclear cells to become induced pluripotent stem cells. Mononuclear cells were isolated from peripheral venous blood by density gradient centrifugation method. The cells are grouped into 4 groups. Group 1 was the control group, which was not exposed to the small molecule. Groups 2-4 were experimental groups exposed to different doses of the small molecule VC6TFZ. Identification of induced pluripotent stem cells was carried out by identifying colony morphology and pluripotent gene expression of Octamer-binding transcription factor-4 (OCT4), Sex-determining region Y-box 2 (SOX2), and Nanog using Real-Time Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR). Colonies with a round shape, large, cobble stone like, and clear boundaries resembling pluripotent stem cell colonies appeared on the 9th day of the induction process. OCT4 and Nanog gene expression were significantly increased in the treatment group compared to the control.

Abstract

Energy drinks are popular among various groups of people, such as teenagers and working individuals. These beverages are consumed to provide additional energy and improve focus. This research investigates the relationship between energy drinks and blood pressure and heart rate in students of the Faculty of Medicine at Universitas Airlangga, Surabaya, Indonesia. The study used the open trial – randomized cross-over study method and collected primary data through experiments. The sample consisted of students from the Faculty of Medicine at Universitas Airlangga, aged 19 to 22 years, with a normal body mass index ranging from 18.5 to 24.9. The systolic, diastolic, and heart rate values were measured before and after consuming energy drinks. A total of 38 research samples were used, including 22 males (57.8%) and 16 females (42.1%). Energy drinks such as Kratingdaeng and Extra Joss showed a significant increase in blood pressure. However, no significant changes were observed in heart rate. The results of the Wilcoxon statistical test, comparing systolic and diastolic conditions before and after consuming Extra Joss, showed p<0.0001. A significance level of p<0.05 indicates a significant effect of energy drinks on the students. The Wilcoxon test for Kratingdaeng also yielded a p<0.0001. For the p-value through the Wilcoxon test on diastolic values before and after consuming Extra Joss and Kratingdaeng, the result was p<0.05. However, the Wilcoxon test for heart rate before and after consuming Kratingdaeng and Extra Joss had a at p<0.05. In the Mann-Whitney statistical test, a p<0.05 was found only in the post-systolic condition, while other conditions had at p≥0.05. In conclusion, energy drinks significantly affected blood pressure, but no significant changes were observed in heart rate.

Abstract

BACKGROUND: Quercetin has been shown to alleviate and prevent atherosclerosis. However, its role in stabilizing atherosclerotic plaques to prevent plaque rupture remains unclear. Therefore, this study was conducted to investigate the effects of quercetin on stabilizing atherosclerotic plaques.METHODS: Thirty-two Wistar rats were objected to a high-fat diet, along with an endothelial injury procedure conducted during the second week to create atherosclerotic plaque models. After six weeks, the subjects were randomly assigned to five groups consist of two control groups and three treatment groups treated with different quercetin dosages. Following the treatment, all subjects were euthanized to collect the left common carotid artery. The stability of the atherosclerotic plaques was evaluated by measuring the expression of matrix metalloproteinase-9 (MMP-9) using real-time polymerase chain reaction, assessing the activity of M1 and M2 macrophages along with the M1/M2 ratio using an enzyme-linked immunosorbent assay, and determining the maximum intima thickness through histopathological examination.RESULTS: Quercetin significantly reduced the expression of MMP-9, increased the activity of M2 macrophages, and lowered the M1/M2 ratio at doses of 10 and 50 mg/kg. However, there was no effect on M1 macrophage activity or maximum intima thickness. Path analysis indicated that quercetin primarily enhanced atherosclerotic plaque stability by reducing MMP-9 expression (p<0.001) and subsequently enhancing M2 macrophage activity (p=0.002).CONCLUSION: Quercetin administration significantly decreased the expression of MMP-9, enhanced the activity of M2 macrophages, and lowered the M1/M2 ratio at specific doses. These findings emphasize the significance of quercetin in stabilizing atherosclerotic plaques.KEYWORDS: atherosclerotic plaque, quercetin, stability, Wistar rats
