Abstract

Background: Diabetes mellitus remains one of the most dangerous illnesses worldwide. The PPAR-gamma protein plays a crucial role in lipid and carbohydrate metabolism, making it a key target for diabetes therapy. Research into plant-derived active compounds for diabetes treatment is increasingly important. Objective: This study aims to evaluate and analyze the interaction of ferulic acid, niazirin, and bakuchiol with the peroxisome proliferator-activated receptor gamma (PPAR-γ) protein using molecular docking. Methods: Molecular docking was employed to assess the interactions between ferulic acid, niazirin, bakuchiol, and the PPAR-γ protein (PDB ID: 2PRG). The analysis focused on binding free energy values, amino acid residue interactions, the number of hydrogen bonds, and bond distances, comparing these results to those of the native ligand and pioglitazone, a known anti-diabetic drug targeting PPAR-γ. Results: The binding free energies for the ferulic acid-PPAR-γ, bakuchiol-PPAR-γ, niazirin-PPAR-γ, native ligand-PPAR-γ, and pioglitazone-PPAR-γ complexes were -5.54 kcal/mol, -8.47 kcal/mol, -6.56 kcal/mol, -10.08 kcal/mol, and -9.94 kcal/mol, respectively. The amino acid residue similarity percentages with the native ligand were 18.18% for ferulic acid, 27.27% for bakuchiol, 18.18% for niazirin, and 81.82% for pioglitazone. The native ligand-2PRG and pioglitazone-2PRG complexes exhibited superior hydrogen bond numbers and shorter bond distances compared to the other compounds. Conclusion: Although bakuchiol showed the most promising interaction among the tested compounds, none surpassed the binding affinity and stability of the native ligand or pioglitazone. Further research is needed to optimize these compounds for potential anti-diabetic therapy.

Background: Hypercholesterolemia is a major risk factor for cardiovascular diseases, with elevated cholesterol levels prevalent in Indonesia. While pharmaceutical treatments are effective, they can be costly and cause side effects, prompting interest in natural remedies. Green tea, rich in bioactive compounds such as catechins, has shown potential in reducing cholesterol levels through its lipid-lowering and antioxidant properties. Objective: This study aimed to evaluate the effect of green tea consumption on total cholesterol levels in employees of the Social Service Office, East Nusa Tenggara Province, Indonesia. Method: An experimental study was conducted involving 38 participants aged 25–55 years, divided into a treatment group (n = 19) and a control group (n = 19). The treatment group consumed 240 ml of green tea twice daily for one week, while the control group received no intervention. Total cholesterol levels were measured using capillary blood and cholesterol test strips pre- and post-intervention. Data analysis was performed using the paired t-test. Results: The treatment group exhibited a significant reduction in total cholesterol levels (mean pre-treatment: 210.95 mg/dL; post-treatment: 188.26 mg/dL; p = 0.003). The control group showed no significant change (pre-treatment: 208.11 mg/dL; post-treatment: 214.37 mg/dL; p = 0.42). Conclusion: Green tea consumption for one week significantly reduced total cholesterol levels, demonstrating its potential as a natural remedy for managing hypercholesterolemia.

Background: Staphylococcus aureus can cause furuncles or boils, painful nodules on the skin. Conventional topical therapies often lead to side effects such as contact dermatitis and pruritus, compounded by the increasing problem of antibiotic resistance. Natural ingredients like celery (Apium graveolens L.) offer promising alternatives due to their antibacterial properties and gentler effects. Objective: This study aimed to formulate a celery extract gel with ideal physical characteristics and evaluate its antibacterial potency against Staphylococcus aureus. Methods: Celery extract gel was prepared using HPMC, celery extract, methylparaben, propylparaben, and propylene glycol. Formulations with various celery extract concentrations were tested alongside mupirocin ointment (positive control) and gel base (negative control) against Staphylococcus aureus using the well-diffusion method. The results were analyzed using the One-Way ANOVA statistical test. Results: Celery extract gel demonstrated strong antibacterial potency at 25% (F1), 50% (F2), and 75% (F3) concentrations and very strong potency at 100% (F4). The One-Way ANOVA analysis showed a significant difference in the mean inhibitory zone diameter between treatment groups (p < 0.05). Conclusion: Celery extract gel exhibits significant antibacterial activity against Staphylococcus aureus, suggesting its potential as a natural alternative for topical therapy in managing skin infections.

Abstract

Background: Ecoenzyme is an organic fermentation product derived from fruit peel waste, offering zero-waste system benefits along with antibacterial, insecticidal, and cleaning properties. Kintamani, a major producer of Siamese oranges (Citrus nobilis) in Bali, generates significant orange peel waste suitable for ecoenzyme production. However, the antioxidant potential of ecoenzymes remains poorly studied. Objective: This study aimed to evaluate the antioxidant activity of ecoenzymes produced from Kintamani Siamese orange peel waste, enhancing their beneficial value. Methods: This experimental study assessed and compared the antioxidant activity of ecoenzymes fermented for 10 days, 1 month, and 3 months. Antioxidant activity was measured using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, with results expressed as IC50 values. Results: Antioxidant activity, classified according to Blois criteria, showed the highest activity after three months of fermentation. The mean IC50 values were 53,612 ppm for 10-day fermentation; 18,753 ppm for 1-month fermentation; and 6,727 ppm for 3-month fermentation. Conclusion: Ecoenzymes derived from Kintamani Siamese orange peel waste exhibited very weak antioxidant activity across all fermentation durations. A 3-month fermentation period is recommended to achieve the highest antioxidant activity compared to shorter durations.

Abstract

Background: Hyperglycemia is characterized by elevated blood glucose levels caused by impaired insulin production or function, leading to oxidative stress. Probiotic-fermented milk containing Lactiplantibacillus pentosus strain HBUAS 53657 (PFM) has antioxidant and antimicrobial properties that may reduce oxidative stress. Objective: This study aimed to investigate the effects of PFM L. pentosus strain HBUAS 53657 on serum glutathione peroxidase (GPx) activity and pancreatic histopathology in hyperglycemic rats. Method: A post-test-only experimental design was conducted using 25 adult male Wistar rats divided into five groups (n = 5 per group): normal control, hyperglycemic control group, and hyperglycemic rats treated with PFM at doses of 1 × 10⁸ CFU/day (P1), 1 × 10⁹ CFU/day (P2), and 1 × 10¹⁰ CFU/day (P3) for 28 days. Serum GPx activity was assessed via spectrophotometry, Langerhans islet area was measured using ImageJ, and islet damage was evaluated using the Ningrum Score. Statistical analysis was performed using One-Way ANOVA and Kruskal-Wallis tests. Results: PFM administration at all doses significantly increased serum GPx activity (p = 0.002), with an optimal dose of 1 × 10⁹ CFU/day (P2). PFM also increased the Langerhans islet area (p = 0.001) and reduced islet damage scores (p < 0.001) in a dose-dependent manner. Conclusion: Probiotic-fermented milk containing Lactiplantibacillus pentosus strain HBUAS 53657 increases serum GPx activity, expands Langerhans islet area, and reduces islet damage in hyperglycemic rats.

Abstract

Background: Indonesia is experiencing a demographic shift, with the elderly population comprising 9.92% (26.82 million) of the total population, 8.21% of whom reside in Jakarta. Oxidative stress is a key contributor to the development of degenerative diseases associated with aging, while antioxidant defenses can mitigate its effects. Objective: This study aimed to assess oxidative stress levels, measured by malondialdehyde (MDA), and antioxidant status, including catalase, reduced glutathione (GSH), and vitamin C, in the elderly population of Jakarta. Methods: A cross-sectional study was conducted with 91 elderly participants from three sub-districts in Jakarta. Erythrocyte lysate samples were analyzed to measure MDA, catalase, and GSH levels, while plasma was used to measure vitamin C. All parameters were quantified using a spectrophotometer. MDA levels and antioxidant status were categorized based on age, blood pressure, and the number of chronic diseases, with statistical analysis performed using the Kruskal-Wallis test. Results: The median MDA level was 2.68 (1.61–5.64) nmol/mL, with the highest levels observed in participants aged 60–64 and those with three chronic diseases. The mean catalase level was 2.41 ± 0.39 U/mL, the median GSH level was 6.16 (2.02–128.07) µmol/mL, and the mean vitamin C level was 10.87 ± 4.9 µg/mL. No significant differences in antioxidant status were observed based on age, blood pressure, or the number of chronic diseases. Conclusion: Oxidative stress is prevalent in the elderly and is particularly influenced by the presence of multiple chronic diseases. However, antioxidant status does not significantly vary with age, blood pressure, or disease burden in this population.

Abstract

Background: Hypertensive disorders, particularly preeclampsia, are major contributors to maternal mortality and neonatal morbidity. Angiogenic imbalance plays a critical role in placental ischemia, a hallmark of preeclampsia. Purpose: This study aimed to investigate the roles of endoglin, soluble endoglin (sEndoglin), and matrix metalloproteinase-14 (MMP-14) in the angiogenic imbalance observed in preeclampsia placentas compared to normal-term placentas. Method: A cross-sectional study was conducted using 68 placental samples: 34 from normal-term pregnancies and 34 from preeclampsia cases. Concentrations of endoglin, sEndoglin, and MMP-14 were measured using the sandwich ELISA method, and protein levels were determined using the Christian Warburg method. Data were analyzed using SPSS version 20. Results: The concentration of endoglin in preeclampsia placentas was slightly higher (1.37 [0.2–2.2] ng/μg protein) compared to normal placentas (1.12 [0.6–14.1] ng/μg protein), although the difference was not statistically significant. In contrast, sEndoglin (0.05 [0.0–0.01] ng/μg protein vs. 0.02 [0.0–0.3] ng/μg protein) and MMP-14 (0.14 [0.1–0.6] ng/μg protein vs. 0.11 [0.1–1.3] ng/μg protein) concentrations were significantly higher in preeclampsia placentas compared to normal placentas. All parameters showed a gradual decrease with advancing gestational age. sEndoglin and MMP-14 demonstrated a strong positive correlation (r = 0.658, p < 0.001), while endoglin and MMP-14 exhibited a moderate positive correlation (r = 0.554, p < 0.001). Conclusion: Endoglin, sEndoglin, and MMP-14 were differentially expressed in preeclampsia placentas, with sEndoglin and MMP-14 significantly elevated. These findings highlight their potential role in angiogenic imbalance and may provide insight into the pathophysiology of preeclampsia.

Abstract

The development of immunological methods in the 1970s and 1980s led to the identification of thyroid peroxidase (TPO) and thyroid stimulating hormone receptor (TSHR) as key players in the onset of autoimmune thyroid diseases (AITD). TSHR is primarily associated with hyperthyroidism, while TPO is linked to hypothyroidism. Advances in understanding TPO and TSHR as biomarkers over recent decades have enhanced their clinical application. This review explores the molecular basis of TPO and TSHR as biomarkers, highlighting their importance in diagnosing AITD and their potential to guide effective therapeutic strategies. Additionally, it discusses the development of lateral flow assay (LFA) kits developed by the authors, which show promise as rapid and reliable diagnostic tools for AITD.
