Abstract

Kombucha is a fermented tea-based beverage containing various bioactive compounds such as polyphenols, flavonoids, organic acids (acetic, gluconic, and glucuronic acids), and probiotic microorganisms produced by the Symbiotic Culture of Bacteria and Yeast (SCOBY). These compounds exhibit antioxidant, anti-inflammatory, and immunomodulatory activities that may support immune function. This study aimed to analyze the pharmacological and pharmacoeconomic aspects of kombucha as a functional immunomodulatory food for elementary-level children with special needs through a systematic literature review approach. Data were collected from Scopus-indexed journals and other reputable scientific databases published between 2016 and 2025. The findings indicate that kombucha exerts pharmacological effects by modulating pro-inflammatory and anti-inflammatory cytokines, enhancing antioxidant activity, and improving gut microbiota balance, thereby contributing to immune homeostasis. From a pharmacoeconomic perspective, kombucha shows potential as a cost-effective preventive functional food intervention with relatively low production costs and potential long-term healthcare cost efficiency. However, direct clinical evidence in children with special needs remains limited, highlighting the need for further experimental and clinical studies to establish safety, efficacy, and comprehensive cost-benefit evaluation.

Abstract

Nasopharyngeal carcinoma is a malignancy of the nasopharyngeal epithelium that is often diagnosed at an advanced stage and is associated with impaired immune regulation in the tumor microenvironment. T-cell immunoglobulin and mucin domain-3 (TIM-3) is an immune checkpoint molecule that plays a role in suppressing the antitumor immune response. This study aims to analyze the relationship between TIM-3 immune response expression and the histopathological type of nasopharyngeal carcinoma. An analytical study with a cross-sectional design was conducted on 40 paraffin blocks of nasopharyngeal carcinoma patients at H. Adam Malik General Hospital, Medan, selected by consecutive sampling. TIM-3 expression was analyzed using real-time polymerase chain reaction (RT-PCR) with the calculation of ΔCT values against the control gene β-actin. Univariate analysis was used to describe the characteristics of the subjects, while bivariate analysis used the Kruskal–Wallis test to assess the relationship between TIM-3 expression and histopathological type. The majority of subjects were male (65%) with a mean age of 48.2 ± 11.1 years. The most common histopathological type was non-keratinizing squamous cell carcinoma (90%). The mean TIM-3 expression was 4.3 ± 1.6 with a median of 4.8 (−0.1–6.7), and 97.5% of samples showed increased expression. The Kruskal–Wallis test showed no significant correlation between TIM-3 expression and histopathological type (p = 0.452). It was concluded that TIM-3 expression is generally increased in nasopharyngeal carcinoma, but is not significantly associated with histopathological type. Further research is needed to evaluate the biological role and therapeutic potential of TIM-3 in this disease.

Abstract

This study aims to identify the species of the Zingiberaceae family found in the Durin Serugun Village Forest and determine their potential use by the local community, especially in the food and health sectors. The methods used were field exploration, interviews with the Karo people, phytochemical tests to detect secondary metabolites in Zingiberaceae rhizomes, and dendogram analysis to determine the phylogenetic relationships between species. The results showed that there are 13 Zingiberaceae species with morphological characteristics and secondary metabolite content such as alkaloids, saponins, tannins, and flavonoids. The community uses rhizomes for traditional medicine to treat various diseases and as a kitchen spice. Dendogram analysis divided the species into two main clusters that reflect morphological similarities and phylogenetic relationships. This study provides an overview of traditional uses as well as the conservation value of Zingiberaceae diversity in the area.

Abstract

Understanding the dynamic organization of organelles is fundamental to biology, yet traditional perspectives often overlook the complex inter-organellar communication that defines cellular physiology. This systematic review synthesizes thirty peer-reviewed articles (2015–2025) to bridge the knowledge gap between static organelle morphology and modern functional dynamics in plant and animal cells. By employing a systematic literature review (SLR) approach with thematic synthesis, this study identifies that while core organelles are conserved, specialized structures such as chloroplasts and large vacuoles in plants versus centrioles and lysosomes in animals exhibit distinct evolutionary adaptations in redox balance and quality control mechanisms. The analysis further reveals a universal reliance on inter-organellar contact sites and autophagy pathways, suggesting that cellular health is maintained through a highly integrated "organelle ecosystem" rather than isolated units. These findings offer critical insights for advancing cell biology education and provide a theoretical framework for future research in metabolic engineering and stress adaptation in tropical biological systems.

Abstract

Microplastics (<5mm) are currently one of the most concerning contaminants in aquatic environments, especially in coastal areas of Indonesia. This literature review aims to identify the types, sources, and abundance levels of microplastics, as well as their potential impacts on aquatic organisms and implications for human health. Microplastics were found at concentrations of approximately 38,000 particles per kilogram of sediment in Indonesian waters and more than 1,500 particles per individual in aquatic animals. Microplastic pollution has been shown to accumulate in the digestive systems of organisms and can translocate to tissues, which can then enter the human food chain. Health impacts that have been identified include the risk of chronic inflammation, digestive system disorders, liver damage, and an increased risk of cancer. Overall, this literature review shows that microplastic pollution in aquatic organisms in Indonesia is at a very worrying level and requires decisive action through reducing the use of plastic materials, improving waste processing, and continuous monitoring. These conditions can harm all aquatic organisms, leading to digestive disorders and even death.

Abstract

Indonesia has the largest mangrove area in the world with high biodiversity potential, including in Muara Kintap Village, Tanah Laut Regency. Mangroves function not only ecologically but also hold medical potential as raw materials for biopharmaceuticals due to their bioactive compound content. This research aims to identify and document mangrove species with potential as herbal medicine ingredients in the mangrove ecosystem of Muara Kintap Village. The study was conducted in September 2025 using purposive observation and the cruising method for primary data collection, supplemented by a systematic literature review for secondary data. The results identified five major species with medicinal potential: Avicennia marina, Sonneratia alba, Avicennia officinalis, Rhizophora apiculata, and Nypa fruticans. The leaves are the most dominant organ with pharmacological potential across all identified species. Secondary metabolite compounds found include flavonoids, tannins, saponins, steroids, and terpenoids, which function as antibacterial, antioxidant, anti-inflammatory, and anticancer agents. This documentation is expected to serve as a foundation for developing herbal-based health products while supporting mangrove conservation efforts in coastal areas.

Abstract

The Social Forestry Area of the Nagari Manganti Protected Forest exhibits high vegetation diversity and the information on vegetation structure in this area remains limited. This study aims to analyze vegetation composition and structure across different growth stages, namely trees, saplings, and understory vegetation, as a scientific basis for sustainable forest management and conservation strategies. The research applied a purposive sampling method, with sample plots systematically established along transect lines. Data for tree and sapling strata were collected using non-destructive sampling methods, while understory vegetation and litter were obtained through destructive sampling. The results indicate that in the tree stratum, Rubiaceae was the dominant family, accounting for 14% of the total composition, consisting of two genera, two species, and six individuals, with Neonauclea sp. exhibiting the highest Important Value Index (IVI) at 26.84%. In the sapling stratum, Rubiaceae, Lauraceae, and Euphorbiaceae functioned as co-dominant families, contributing 18%, 13%, and 10% of the composition, respectively, with Litsea sp. recording the highest IVI at 22%. In the understory stratum, Rubiaceae was the most dominant family (36%), followed by Sapotaceae (11%) and Myrtaceae (10%), while Saraca sp. showed the highest IVI at 40.7%. Therefore, efforts to protect large-diameter trees need to be prioritized  because they play an important role in carbon storage and ecosystem stability. They also maintain dominant species and are used in vegetation rehabilitation and enrichment activities, especially in landslide-prone areas and riverbanks.

Abstract

Chronic ultraviolet B (UVB) radiation induces progressive alterations in skin tissue that contribute to photoaging, while the involvement of Transforming growth factor-β (TGF-β) in this process remains unclear. This study aimed to analyze dermal TGF-β expression in the skin of BALB/c mice following chronic UVB irradiation. This true experimental study employed a post-test-only control group design, with 16 BALB/c mice divided into a normal control group (K1) and a UVB-exposed group (K2). Mice in group K2 were exposed to UVB at 1 minimal erythemal dose (MED; 240 mJ/cm²) six times per week for 27 days (24 exposures). Skin samples were collected immediately after the final exposure and analyzed using immunohistochemistry. Dermal TGF-β expression was significantly higher in the UVB-exposed group (17.70 ± 1.25) compared to the control group (11.08 ± 0.66) (p < 0.05). Chronic UVB exposure induces upregulation of dermal TGF-β expression, indicating altered regulation of this growth factor under prolonged inflammation. These findings provide preliminary evidence of altered TGF-β regulation under chronic UVB exposure and support further investigation into its role in photoaging.

Abstract

Escherichia coli is one of the gram-negative bacteria that produces the Extended Spectrum Beta-Lactamase (ESBL) enzyme and has a role in resistance to the beta-lactam group. The presence of E. coli bacteria that produce ESBL in food, especially in fish such as milkfish (Chanos chanos) poses a potential source of the spread of antimicrobial resistance (AMR) in humans. This study aims to determine the prevalence of ESBL-producing E. coli in the intestinal flora of milkfish sold in traditional markets in Surabaya City. This study used a descriptive observational method with a cross-sectional approach. There were 50 samples of milkfish intestines taken from several stalls in traditional markets randomly. Identification of E. coli bacteria by planting in MacConkey media with 4 µL/ml cefotaxime followed by the Double Disk Synergy Test (DDST). Of the 50 milkfish intestine samples used, 34 (68%) samples showed positive results for ESBL-producing E. coli. The high prevalence may indicate that the potential for the spread of antimicrobial resistance through the food chain, food hygiene management and controlling the use of antibiotics in fish farming need serious attention.
