Abstract

Osteoporosis increases fracture risk and reduces quality of life in menopausal women. Although physical activity, such as walking and bone joint exercise, is known to help maintain bone health, its effectiveness needs further examination. The aim of this study was to analyze the effects of physical activity, in particular walking and bone joint exercise, on enhancing bone remodeling in menopausal women. A randomized controlled trial was conducted among menopausal women and allocated into three groups: walking, bone joint exercise, and control groups. The intervention was provided for eight weeks, with the outcomes measured before and after the intervention. The study assessed five bone remodeling biomarkers: estrogen, parathyroid hormone (PTH), receptor activator of nuclear factor kappa-β ligand (RANKL), tumor necrosis factor-alpha (TNF-α), and bone mineral density (BMD). The paired sample student t-test and ANOVA were used to assess the effects of the interventions. The results indicated that, compared to pre-intervention, both walking and bone joint exercise significantly increased the estrogen (p=0.026 and p=0.023, respectively), decreased RANKL (p=0.019 and p=0.002, respectively), decreased PTH levels (p=0.022 and p=0.048, respectively) and increased the BMD scores (p=0.001 and p<0.001, respectively). In the control group, none of the remodeling biomarkers significantly changed except the mean level of TNF-α, which was increased significantly (p=0.001). This study highlights that structured exercise, such as walking and bone joint exercise, can significantly enhance bone remodeling markers in menopausal women. Therefore, implementing such physical activities into management may provide benefits to menopausal women.

Abstract

Sodium metabisulfite is widely used as a preservative in many food and beverage products, yet its potential effects on cognitive and motor functions at low concentrations remain poorly understood. Evaluating learning, short-term memory, and motor activity is essential, as these functions are critical indicators of neurological health and could be impacted by low-level exposure to sodium metabisulfite. The aim of this study was to investigate the effects of sublethal concentrations of sodium metabisulfite on cognitive and motor functions using Drosophila melanogaster (fruit flies) as the model organism. Different levels of sodium metabisulfite were administered to male and female fruit flies, and their learning and short-term memory were observed. Additionally, their climbing activity with and without stressors (heat shock, ultraviolet A exposure, or energy deprivation) was examined. Our findings indicated that sodium metabisulfite did not impair learning, short-term memory, or motor activity. Furthermore, sodium metabisulfite did not affect the motor activity of fruit flies under heat, ultraviolet A, and energy-deprived conditions. In conclusion, our results suggested that the sublethal concentration of sodium metabisulfite did not harm cognitive and motor functions and did not exacerbate the effects of environmental stressors.

Abstract

The coexistence of depression and type 2 diabetes mellitus (T2DM) can significantly worsen disease prognosis and lower quality of life. Emerging evidence suggests that vitamin D deficiency contributes to the progression of T2DM and is closely associated with the development of depression. The aim of this study was to investigate the effects of cholecalciferol on depression in patients with T2DM, exploring its mechanisms by analyzing its impact on C-peptide, serotonin, and neurotrophin-3 levels. A double-blind, randomized, placebo-controlled clinical trial was conducted at Cipto Mangunkusumo General Hospital, Jakarta, Indonesia, from April 2021 to September 2022. Patients with T2DM and depressive symptoms were randomly assigned to two groups: received 4000 IU of cholecalciferol daily and received a placebo for 12 weeks. Depression was assessed using the Beck Depression Inventory-II (BDI-II) before and 12 weeks after the intervention. The levels of C-peptide, serotonin, and neurotrophin-3 were measured at the end of the fourth week of intervention using the enzyme-linked immunosorbent assay (ELISA) method. Between-group comparisons were made using independent Student t-tests and Mann-Whitney U tests. Paired Student t-tests or Wilcoxon tests were applied for within-group comparisons between pre- and post-intervention. A total of 70 T2DM patients with depression were included in this study, comprising 38 patients in the cholecalciferol group and 32 in the placebo group. C-peptide levels increased significantly in the cholecalciferol group compared to the placebo group (p=0.006). No significant differences were observed in serotonin and NT-3 levels between the cholecalciferol group compared to the placebo group. The cholecalciferol group had a significantly greater reduction in BDI-II scores compared to the placebo group (p<0.001). This trial highlights that taking cholecalciferol might help ease mild to moderate depression symptoms in patients with T2DM by enhancing c-peptide levels, though its effects on serotonin and neurotrophin-3 are still unclear.

Abstract

Congenital heart disease (CHD) represents nearly one-third of congenital birth defects annually, with ventricular septal defect (VSD) being the most common type. The aim of this study was to explore the role of specific GATA binding protein 6 gene (GATA6) mutations as a potential etiological factor in the development of VSD through an in silico approach. Data were collected from the human gene databases: DisGeNET and GeneCards, with protein-protein interaction networks constructed via STRING and Cytoscape. Gene ontology and pathway enrichment analyses were conducted using DAVID, with data analysis in R with significance set at FDR p<0.05. Target single nucleotide polymorphisms (SNPs) of GATA6 were obtained from NCBI dbSNP, and non-synonymous single nucleotide polymorphism (nsSNP) effects were predicted using SIFT, PolyPhen-2, I-Mutant 2.0, Fathmm, MutPred 2.0, SNP&GO, and PON-P2. Conserved regions of GATA6 were analyzed using ConSurf, with functional classification, variant conservation, and stability changes evaluated in Google Colab. Multiple sequence alignment was performed using ClustalW. Mutation modeling and molecular dynamics analysis, using GROMACS, revealed that among 87 intersecting genes, 16 proteins were interconnected with GATA6, showing a centrality value of 0.4378. Gene ontology analysis highlighted atrioventricular canal development, protein-DNA complexes, and transcription factor regulation as key processes for cardiac development, especially in the ventricular septum. NsSNP and molecular dynamics analyses identified rs387906818 and rs387906820 as having the highest pathogenic potential for VSD due to amino acid structural changes.

Abstract

Chronic limb-threatening ischemia (CLTI) is the most severe manifestation of peripheral arterial disease (PAD) and imposes a significantly high burden due to its high risk of mortality and amputation. Revascularization is the first-line treatment for CLTI; however, the amputation rate remains high, and approximately one-third of patients are not eligible for this treatment. Therefore, there is an urgent need for more effective therapeutic strategies. The aim of this study was to investigate the effects and mechanisms of human umbilical vein endothelial cells (HUVECs)-derived exosomes on neovascularization and the degree of necrosis in a hindlimb ischemia model and to study the biological processes underlying their mechanisms. This is an in vivo experimental study with a post-test-only control group design. Forty BALB/c mice were randomized to receive injections of exosomes, conditioned media, and phosphate-buffered saline (PBS) one day after unilateral double ligation. A sham-operated group was also included as a control. Capillary density, arteriole lumen diameter, and histopathological necrosis were measured after seven days, while clinical necrosis was observed daily. MicroRNA profiling, in silico analysis, and transcriptomic analysis of vascular endothelial growth factor (VEGF) mRNA expression were performed to determine the possible biological processes. No amputation was found in the exosome group, as well as in the conditioned media and sham-operated groups, compared to three out of seven mice (43%) in the PBS group. The capillary density was higher in the exosome than in the PBS group (p=0.026). The arteriole lumen diameter in the exosome group was larger than in the PBS (p=0.033) and sham-operated (p=0.034) groups. The scores of clinical necrosis and histopathological necrosis in the exosome group were lower than the PBS group (p=0.005), while the histopathological necrosis scores were also lower but statistically insignificant. In silico analysis showed improvement in neovascularization and necrosis, possibly through energy regulation, PI3K/AKT and TGF-β activation, the ubiquitin-proteasome system, and tyrosine kinases receptors. HUVEC exosomes were associated with lower VEGF mRNA expression, which may indicate a more effective compensatory mechanism under ischemic conditions. The exosome group had the lowest VEGF mRNA expression compared to other groups, although the difference was not statistically significant. This study highlights that HUVECs-derived exosomes improve neovascularization and decrease necrosis in a hindlimb ischemia mice model, potentially by modulating several possible mechanisms.

Abstract

Velvet bean is a native Indonesian legume containing L-dopa, yet it remains underutilized. The aim of this study was to analyze the effects of different types of tempe (soybean, velvet bean, and their combination) on cognitive function, brain histology, dopamine levels, and serum β-amyloid in rats, as well as to identify the parameters most influencing cognitive function, including brain mass and volume, hippocampal neuron count, and dopamine and β-amyloid levels. An experimental study was conducted using a completely randomized design with one factor: the protein source of diet. Five rat groups were included based on protein sources: non-protein, casein control, soybean tempe flour, velvet bean tempe flour, and a combination of soybean and velvet bean tempe flour. This study examined cognitive performance by measuring maze completion time, while brain mass and volume, hippocampus histology for neuron cell counts in the dentate gyrus section, cornu ammonis 1 (CA1), and cornu ammonis 3 (CA3), brain dopamine and β-amyloid serum levels were measured after eight weeks of intervention. Our data indicated that rats deprived of protein had significantly slower maze completion times (p<0.001), underscoring the importance of protein in cognitive processes. Rats treated with non-protein rations had significantly lighter brain masses (p<0.001) than other treatments. Histological analysis of the hippocampus showed that the three types of tempe rations helped maintain the number and density of neuron cells in the dentate gyrus and CA3 of the hippocampus. Additionally, the protein in the ration could increase dopamine levels and suppress serum β-amyloid levels. There was a strong correlation between brain volume and neuron cell density in the dentate gyrus section of the hippocampus with cognitive function. These results highlight the promising role of combination tempe in increasing cognitive function, brain mass and volume, dopamine levels, and suppressing serum β-amyloid.

Abstract

Research related to the development of diagnostic biomarkers in lung adenocarcinoma in various countries is important. Research on microRNA as a biomarker in lung adenocarcinoma varies depending on the population, specimen, and technology used for profiling and validation. The aim of this study was to map and analyze bibliometric data of publications related to the topic of microRNA as a candidate biomarker in lung adenocarcinoma and to determine any potential research gaps. A total of 8,506 articles were collected from Crossref, Google Scholar, Semantic Scholar, PubMed, and Scopus databases using Harzing's Publish or Perish platform. A systematic search was conducted using four keywords: “profiling,” “validating,” “microRNA,” and “lung adenocarcinoma,” and synonyms of these keywords based on the MeSH on NCBI. The data extraction process followed the chart from PRISMA-P. The article’s elimination was conducted using Mendeley Desktop and then was analyzed based on the authors' keywords using VOSviewer and Biblioshiny. A bibliometric analysis of 692 relevant articles identified four primary research clusters: (1) microRNA (19 keywords), which highlights its potential as a biomarker for early detection and diagnosis; (2) lung adenocarcinoma (18 keywords), reflecting advancements in lung cancer research; (3) liquid biopsy (19 keywords), emphasizing the growing interest in non-invasive diagnostic methods; and (4) bioinformatics (nine keywords), underscoring the role of computational approaches in transcriptomic analysis. As a primary topic, microRNAs have become a focal point of research for diagnosing lung cancer across various stages and as biomarkers for cancer cell proliferation, invasion, migration, and metastasis. Numerous studies have demonstrated the successful application of microRNAs in lung cancer diagnosis in the last decade, although the reported types of microRNAs are inconsistent. Therefore, further research on this topic should be continuously conducted, particularly to validate the types of microRNAs and the types of environments that influence them.

Abstract

The incidence of psychosomatic disorders is increasing in Indonesia, and therefore screening instruments that are culturally appropriate for the Indonesian population are needed. The aim of this study was to assess the validity and reliability of the Shatri Sinulingga psychosomatic test (SSPT) questionnaire as a screening instrument for psychosomatic disorders in Indonesia. An analytic descriptive cross-sectional study divided into two stages (questionnaire formulation and distribution through the Psikosom.id application) was conducted in 2023. The validity test was carried out using the product moment technique, and Cronbach's alpha assessment was carried out to evaluate the reliability of the questionnaire. A total of 372 participants were included, with a mean age of 39.24 years old. The SSPT questionnaire scores had strong correlations with the scores of hospital anxiety and depression scale (HADS) (r=0.668; p<0.001) and the Symptom Checklist-90 (SCL-90) (r=0.674; p<0.001); and moderately correlated with the score of fatigue severity scale (FSS) (r=0.505; p<0.001) and Pittsburgh Sleep Quality Index (PSQI) (r=0.492; p<0.001). The correlation coefficient (r) value of each SSPT question ranged from 0.389–0.726, and all r higher than r table with an overall Cronbach’s alpha of 0.744. The SSPT questionnaire's strong predictive performance: had a sensitivity of 75.6% and specificity of 71.4% with an area under the curve (AUC) of 81% (95%CI: 76.6–85.4%; p<0.001) to HADS; sensitivity of 80% and specificity of 58.6% with an AUC of 75.1% (95%CI: 70–80.2%; p<0.001) to FSS; sensitivity of 64% and specificity of 67.5% with an AUC of 71.2% (95%CI:  65.4–77%; p<0.001) to PSQI; and had sensitivity of 78% and specificity of 67.4% with an AUC of 80.9% (95%CI:  76.6–85.3%; p<0.001) to SCL-90. The study highlights that the SSPT questionnaire is valid and reliable to be used as a screening instrument for psychosomatic disorders in Indonesia.

Abstract

The coronavirus disease 2019 (COVID-19) pandemic has encouraged global vaccine research, yet vaccine effectiveness in the elderly remains a concern due to immunosenescence. The aim of this study was to compare the cytokine response elicited by an inactivated virus-based COVID-19 vaccine between elderly and young adults, focusing on key cytokines involved in cellular and humoral immunity: tumor necrosis factor-alpha (TNF-α), interleukin (IL)-2, IL-6, IL-10, and interferon-gamma (IFN-γ). A cross-sectional study was conducted in the Jakarta-Bogor region of Indonesia from January 2023 to December 2023. The study population was divided into two age cohorts: elderly (60−85 years) and younger adults (30−40 years). Blood samples were collected twice, after the first booster dose and four weeks after the second booster dose. Serum cytokine concentrations were measured using Luminex assays with microparticles conjugated to monoclonal antibodies against TNF-α, IL-2, IL-6, IL-10, and IFN-γ. Comparisons of the cytokine levels were conducted using Student’s t-tests or Mann-Whitney U tests as appropriate. A total of 74 individuals were included, with 37 each in the elderly and young adult groups. The results showed significant differences in cytokine responses between the two age groups. After the first booster, the levels of IL-6 and IFN-γ were significantly higher in young adults compared to the elderly. After the second booster, the levels of IL-6 were still significantly higher in the young adult group compared to the elderly group (p=0.001). Data indicated that after the second booster dose, the levels of TNF-α increased significantly in the young adult group only (p=0.004), while the levels of IL-2 (p=0.040) and IFN-γ (p=0.006) increased in the elderly group only compared to after the first dose. IL-10 levels increased in both groups (both had p=0.020). This study highlights that young adults had stronger pro-inflammatory responses, while the elderly relied more on IL-2 and IFN-γ for T-cell immunity, suggesting the need for vaccination strategies for the elderly to optimize immune responses.

Abstract

The current standard treatment for ovarian cancer is a combination of cytoreductive surgery and platinum-based chemotherapy; however, many patients develop resistance, leading to a high recurrence rate. The aim of this study was to analyze the expression of PD-L1, CTR-1, VEGF, and p53 in epithelial ovarian cancer (EOC) patients, comparing those sensitive and resistant to platinum-based chemotherapy. A cross-sectional study was conducted among EOC patients who underwent surgery and platinum-based chemotherapy between 2020 and 2023 at Dr. Soetomo General Academic Hospital, Surabaya, Indonesia, with evaluations performed six months post-chemotherapy. The expression of PD-L1, CTR-1, VEGF, and p53 were measured using immunohistochemistry (IHC) and compared between chemotherapy-sensitive and resistant patients. A total of 65 patients were included: 31 resistant and 34 sensitive cases. The results showed higher PD-L1 expression in the resistant group compared to the sensitive group (mean combined positive score (CPS) of 0.46±0.29 vs 0.17±0.09, p<0.001). The CTR-1 expression was lower in the resistant group (immunoreactive score 2.90±1.30) compared to the sensitive group (immunoreactive score 6.82±2.68) with p<0.001. VEGF and p53 expression were also higher in the resistant group (6.68±2.59 vs 2.76±1.10 and 64.68±13.54% vs 30.15±13.06%, respectively) compared to the sensitive group, with both having p<0.001. The study suggests that increased expression of PD-L1, VEGF, and p53 and decreased CTR-1 expression are associated with platinum-based chemotherapy resistance among EOC patients. Therefore, these biomarkers might have the potential for predicting treatment responses and understanding resistance mechanisms.
