Abstract

Mesenchymal stem cells (MSCs) have gained significant interest for their potential application in repairing damaged tissues through immunomodulatory functions. Vitamin D has been shown to regulate both the innate and adaptive immune systems. Active forms of Vitamin D, such as 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) are known to influence the action of mesenchymal stem cells (MSCs) in several mechanisms, such as stimulating their proliferation and osteogenic differentiation, as well as tissue regeneration. This study aimed to investigate the effects of vitamin D supplementation on the biological properties and expression of cytokines and growth factor genes in MSCs isolated from the human umbilical cord (UC). MSCs were isolated from Wharton’s jelly (WJ-MSC) of UC, cultured, and supplemented with various concentrations of vitamin D3. The Cell Counting Kit-8 (CCK-8) assay was used to measure cell viability, and a scratch wound healing assay was conducted to evaluate the migration capacity of MSCs. The mRNA expression levels of vascular endothelial growth factor (VEGF), tumor necrosis factor (TNF)-α, and interleukin (IL)-6 were quantified using reverse transcription-polymerase chain reaction (RT-PCR). This study showed that supplementation with 50 nM of vitamin D3 for 48 h significantly increased the viability and migratory capacity of MSCs. Furthermore, vitamin D supplementation significantly decreased the mRNA levels of TNF-α and VEGF but did not affect IL-6 gene expression compared to the control group. These findings suggest that vitamin D supplementation can enhance the biological characteristics and modulate the expression of key immunomodulatory factors in MSCs, potentially improving the effectiveness of MSC-based therapies.

Abstract

Malnutrition, especially among children under five, remains a significant public health concern in Indonesia, including Riau Province. One potential effort to address this issue is the utilization of traditional fermented foods from Kuantan Singingi Regency, such as pekasam, sarobuong, puduong, and cangkuok semaung. These foods are rich in nutrients, including protein, carbohydrates, amino acids, minerals, and probiotics beneficial to health; however, they are on the verge of extinction.This community service program aimed to revitalize traditional Kuansing fermented foods through a science and technology-based training approach. The program implementation involved video demonstrations of traditional food preparation, distribution of pocket books, and interactive discussions with health cadres, as well as pregnant and breastfeeding mothers, and mothers with toddlers.The results showed high enthusiasm among participants, demonstrated by their active involvement in discussions and question-and-answer sessions. The training not only improved participants’ knowledge but also fostered awareness and a sense of ownership of local food, while simultaneously opening opportunities for small-scale household businesses.

Abstract. Saryono, Ismawati, Pratiwi NW, Devi S, Sipayung MY, Suraya N. 2023. Isolation and identification of lactic acid bacteria from traditional food sarobuong of Kuantan Singingi District, Riau, Indonesia. Biodiversitas 24: 2201-2206. Lactic acid bacteria (LAB) are commonly used as probiotic agents in fermented processed foods like sarobuong. Sarobuong is a traditional food from Kuantan Singingi District made by fermenting bamboo shoots. In this study, the isolation and purification of LAB from sarobuang were done using MRS agar media with the streak quadrant method: macroscopic and microscopic observations and biochemical and physiological tests to identify isolates. The antibacterial ability of LAB isolates was used against pathogenic bacteria Escherichia coli and Staphylococcus aureus. The results showed that 21 isolates were gram-positive bacteria in the form of bacilli and coccus, while carbohydrate degradation was homofermentative. The results of the antibacterial test of 21 isolates indicated by LAB against E. coli and S. aureus bacteria showed a clear zone ranging from 0.1 to 0.6. The highest antibacterial activity against pathogenic bacteria E. coli was observed in isolate RB1, while for pathogenic bacteria S. aureus, it was in isolate R15. The results obtained from several isolates that have been tested showed that LAB isolated from sarobuong had relatively higher activity than the control and was identified as Lactobacillus and Streptococcus.

Abstract

Diabetes mellitus is a major global health problem. Lipotoxicity is a key cause of insulin resistance that ultimately leads to pancreatic damage in type 2 diabetes mellitus. One plant with potential to prevent pancreatic damage is the Seri plant (Muntingia calabura). This study aimed to analyze the effect of ethanolic extract of Muntingia calabura leaves on pancreatic damage in rats induced by a high-fat diet (HFD). This was an experimental study with a post-test-only design. A total of 28 male Wistar rats weighing 120–200 grams were divided into four groups: K1 received standard feed (20 g/rat/day) and water ad libitum; K2 received a 50% high-fat diet (20 g/rat/day); K3 received the same HFD plus Muntingia calabura leaf extract (100 mg/kg/day); and K4 received HFD plus pioglitazone (6 mg/kg/day). Treatments were administered for 8 weeks, followed by termination for pancreatic histological examination. The variables studied were supplementation of Muntingia calabura ethanolic extract and the degree of pancreatic insulitis. Histological preparations were stained with hematoxylin-eosin, and insulitis was scored. Data were analyzed using IBM SPSS with Kruskal–Wallis and Mann-witney tests. Results showed no insulitis in K1, while mild insulitis was observed in K2, K3, and K4. A significant difference in histological scores was found between K1 and K2 (p = 0.03), whereas no significant differences were observed among other groups. In conclusion, 8 weeks of HFD induced mild insulitis in rats, while Muntingia calabura leaf extract and pioglitazone did not demonstrate protective effects against insulitis.

Abstract

Atherosclerosis in diabetes mellitus (DM) patients is prevented by using inulin to increase glucose metabolism and reduce cholesterol synthesis. Therefore, this research aimed to analyze dahlia tuber inulin extract to determine the effect on coronary artery histopathology in type 2 DM rats. A total of 20 male Wistar rats were divided into five groups, namely negative control without treatment, DM, DM + 0.5 mg/gBW/day inulin extract, DM + 1 mg/gBW/day inulin extract, and DM + 1.5 mg/gBW/day inulin extract. Furthermore, DM induction was carried out by administering 60 mg/kgBB streptozotocin and 120 mg/kgBB nicotinamide. The results of coronary artery histopathology readings showed that the highest and lowest scores of atherosclerosis were in Groups II (0,91±0,17) and V (0,08±0,1), respectively. Data analysis using Kruskal Wallis test reported significant results (p<0.05), while Mann-Whitney test showed differences between control and DM, DM, and inulin groups (III, IV, V). In this context, the administration of dahlia tuber inulin extract to rats induced by Type 2 DM prevented atherosclerosis in histopathological image of coronary artery.

Abstract

Inulin is a natural polysaccharide that improves glucose metabolism and reduces cholesterol levels through the formation of short-chain fatty acids, which may contribute to preventing atherosclerosis in type 2 diabetes mellitus (T2DM). Therefore, this study aimed to evaluate the effect of dahlia tuber inulin extract on the thickness of the thoracic aortic tunica intima-media (TIM) in T2DM-induced rats. A total of 20 male Wistar rats were divided into five groups: control, T2DM, T2DM + 0.5 mg/gBW/day inulin extract, T2DM + 1.0 mg/gBW/day inulin extract, and T2DM + 1.5 mg/gBW/day inulin extract. T2DM induction was performed using 60 mg/kgBW streptozotocin and 120 mg/kgBW nicotinamide. Measurement of TIM thickness was conducted using a Leica light microscope with hematoxylin-eosin staining. The results showed no statistically significant differences among the groups (p = 0.051), although a decreasing trend in TIM thickness was observed at the 1.5 mg/gBW/day dose. In this context, dahlia tuber inulin extract demonstrated a tendency to reduce TIM thickness in T2DM-induced rats.
