Abstract

Abstract: Noncommunicable diseases, such diabetes mellitus, atherosclerosis and cancer, caused by inter alia imbalance between free radicals and antioxidants within the body, known as oxidative stress. Antioxidants from outside the body are required as antioxidants within the body are not enough to ward off excessive free radicals. Amaranthus hybridus L. plant is quite popular among Indonesian people due to its fast harvest and advantages for health, including its natural antioxidants potency. This study aimed to determine the comparison of antioxidant activities among n-hexane, ethyl acetate, and aqueous extract of A. hybridus L. leaves. This was an experimental laboratory study. Amaranthus hybridus L. simplicia extracted with maceration in n-hexane, ethyl acetate and aquadest. Antioxidant activities of n-hexane, ethyl acetate, and aqueous extract of A. hybridus L. were examined with 2.2-diphenyl-1-picrylhydrazyl (DPPH) in 517 nm wavelength by using microplate reader. The results showed that the IC50 values of A. hybridus L. n-hexane, ethyl acetate, and aqueous extract respectively were 131.81 mg/mL, 103.53 mg/mL, and 79.61 mg/mL. In conclusion, there are differences in antioxidant activities between n-hexane, ethyl acetate, and aqueous extract of A. hybridus L. This occur due to differences in the polarity of each solvent.

Abstract

Water is crucial for human survival, serving both consumption needs and daily activities. However, water contamination often occurs when it is not managed and stored properly. Contaminated drinking water can pose health risks, causing various digestive diseases and even death, especially in children. Therefore, the management and storage of water require special attention. Indonesian communities, especially those in the RW 006, Tanjung Duren Selatan, are still limited in gathering clean water without proper water management for it to be made suitable for consumption. In response to this concern, a program was implemented to enhance awareness and empower the residents of RW 006, Tanjung Duren Selatan, focusing on improving environmental sanitation and the effective management of safe drinking water. The activities took place at the secretariat office of RW 006, Tanjung Duren Selatan, on Friday, November 10, 2023, from 08:30 to 10:15 AM. A total of 25 participants filled out attendance and completed pre-test questionnaires. Participants were then provided with education and training by the team on environmental sanitation, Community-Based Total Sanitation (STMB), proper management of household waste, and the handling of water intended for consumption. The post-test results showed an improvement in participants' knowledge and understanding regarding the enhancement of environmental sanitation and the management of water ready for consumption in households. It is hoped that participants will serve as links in communication and educators within the local community, ultimately contributing to improved sanitation and an enhanced quality of life.

Abstract

Bad breath, or commonly known as halitosis, is a health problem that is often overlooked. It can harm a person's daily life, including social isolation, anxiety, and discomfort. Halitosis can be divided into two types: genuine halitosis (related to oral issues) and delusional halitosis (related to false perceptions). Most cases of halitosis are caused by oral hygiene problems such as reduced saliva, dry mouth, gingivitis, periodontitis, and the use of dentures. Specific bacteria in the mouth can produce foul-smelling compounds known as volatile sulfur compounds (VSCs), such as methyl mercaptan and hydrogen sulfide. Additionally, halitosis can also result from systemic issues or bad habits. It is important to provide education to the community on how to address halitosis and maintain oral hygiene. Steps like regular tooth brushing, tongue cleaning, using dental floss, and avoiding strongly aromatic foods can help reduce the risk of halitosis. In the community of RT015/RW008, Kelurahan Jatipulo, West Jakarta, this education is particularly crucial because the level of knowledge about oral health is low. Through education and training, it is hoped that the community can recognize the causes of halitosis and address the issue before seeking medical help. This will improve the quality of life for the community, boost their self-confidence, and help prevent more serious oral health.

Abstract

Recent advances in cancer treatment have focused on developing alternative therapies with reduced adverse effects. Chemoprevention using natural products derived from plants has gained significant attention. Apium graveolens has demonstrated anticancer properties against various cancer cell types, suggesting its potential efficacy against tongue cancer cells. The aim of this study was to evaluate the cytotoxic effects and mechanisms of action of Apium graveolens leaf ethanolic extract (AGLEE) on the HSC-3 tongue cancer cell line. The leaves were processed and extracted with 70% ethanol to obtain an ethanolic extract. HSC-3 cells were cultured, subjected to starvation, and pre-treated with or without Z-DEVD-FMK, a caspase-3 inhibitor. Subsequently, the cells were treated with or without doxorubicin or varying concentrations of AGLEE. To assess cell viability and apoptosis, MTT and sub-G1 assays were performed. Additionally, treated HSC-3 cells were collected, lysed, and analyzed for levels of cleaved-caspase-3 and cleaved-poly (ADP-ribose) polymerase (cleaved-PARP) using ELISA. The inhibitory concentration (IC50) value of AGLEE for reducing viable HSC-3 cells was determined to be 48.29 μg/mL. AGLEE significantly decreased HSC-3 cell viability and increased the percentage of apoptotic cells. It exhibited a concentration-dependent reduction in cell viability and an increase in apoptosis. Furthermore, the extract elevated the levels of cleaved-caspase-3 and cleaved-PARP in HSC-3 cells. Pre-treatment with Z-DEVD-FMK reduced the levels of cleaved-caspase-3 and cleaved-PARP induced by AGLEE. Taken together, AGLEE could be proposed as a potential natural therapeutic agent by inducing apoptosis through the caspase-3/PARP pathway in tongue cancer cells.

Abstract

Infections caused by pathogenic bacteria such as Pseudomonas aeruginosa present significant challenges in clinical practice, particularly due to rising resistance to conventional antibiotics. The development of environmentally friendly, nanotechnology-based antibacterial agents is considered a promising alternative. This study aimed to evaluate the antibacterial activity of a nanocomposite comprising silver nitrate (AgNO₃), Cymbopogon citratus leaf extract, and chitosan against P. aeruginosa. The nanocomposite was synthesized using a green synthesis method, with plant extract serving as a natural reducing agent and chitosan as a nanoparticle stabilizer. Antibacterial activity was assessed via disk diffusion against five concentrations (6.25, 12.5, 15, 25, and 50 mg/mL), and compared to positive (chlorhexidine) and negative (acetic acid) controls. The results showed that the 6.25 mg/mL concentration produced the largest inhibition zone (average 11 mm), although it did not surpass the effectiveness of chlorhexidine. The inhibition zones remained stable for up to 72 hours, indicating sustained antibacterial activity. A decline in efficacy at 50 mg/mL was observed, likely due to nanoparticle aggregation and biological saturation. These findings support the potential of AgNO₃–C. citratus–chitosan nanocomposite as a natural-based alternative antibacterial agent. Further studies are recommended to characterize its physicochemical properties, elucidate its mechanism of action, and evaluate its toxicity and applicability in pharmaceutical and biomedical contexts.

Abstract

BACKGROUND: Inositol hexakisphosphate (InsP₆) exhibits anticancer activity, especially by inducing intrinsic and extrinsic apoptotic pathways. However, there is still no molecular docking evidence that directly examines InsP₆ interactions with either upstream or downstream apoptotic regulators. Therefore, the current study was conducted to investigate the molecular docking of InsP₆ to caspases as upstream/downstream apoptotic regulators.METHODS: Ligands including InsP₆, InsP₅, InsP₄, histone deacetylase inhibitor, and caspase inhibitors were retrieved from PubChem, while target proteins (histone, caspase-8, caspase-2, and caspase-3) were obtained from the Protein Data Bank. Ligand toxicity was predicted using ProTox-3.0, and physicochemical properties were analyzed with SwissADME. Ligand structures were energy-minimized using PyRx with the Universal Force Field, while proteins were prepared by removing water molecules and non-essential heteroatoms in BIOVIA Discovery Studio. Molecular docking was conducted using CB-Dock 2.0, with binding poses selected based on the lowest Vina score, and ligand–protein interactions were visualized in Discovery Studio.RESULTS: Molecular docking results showed that InsP₆ bound strongly to histone, caspase-8, caspase-2, and caspase-3 with affinities comparable to reference inhibitors, forming multiple hydrogen bonds with key active-site residues. InsP₆, InsP₅, and InsP₄ exhibited several similar binding sites to caspase-3, with only minor differences in binding affinity.CONCLUSION: InsP₆ shows strong binding to histone, caspase-8, caspase-2, and caspase-3 based on in silico results, supporting its role in inducing both extrinsic and intrinsic apoptotic pathways. Taken together, InsP₆ could be a potential inducer of apoptosis in cancer cells.KEYWORDS: cancer, apoptosis, InsP₆, InsP₅, InsP₄, caspase, in silico, molecular docking

Abstract

BACKGROUND: Oral squamous cell carcinoma (OSCC) of the tongue is an aggressive cancer with a poor prognosis due to its resistance to standard treatments. Stenochlaena palustris, a medicinal fern containing bioactive compounds, has shown potential anticancer properties. However, there is a lack of studies addressing the effects of S. palustris ethanol extract (SPEE) on tongue cancer. This study examined the effects of SPEE on the cell viability and cell cycle of human squamous cell carcinoma (HSC)-3 tongue cancer cells.METHODS: SPEE was prepared with the maceration method. HSC-3 cells were treated with SPEE at concentrations of 100, 500, and 1000 µg/mL for 24 and 48 hours. Cell viability was measured with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Cell cycle analysis was performed using flow cytometer. Immunoblotting was used to measure amount of cell cycle regulators, protein 21 (p21) and protein 27 (p27).RESULTS: SPEE treatment led to a significant decrease in HSC-3 viable cells in a concentration- and time-dependent manner, with the most pronounced effect at higher concentration and prolonged treatment time. There was a slightly increase in the percentage of cells in the Sub-G1 phase in SPEE-treated group, meanwhile there was a significant increase in the percentage of cells in the G1-phase. Increased amount of p21 and p27 were observed in SPEE-treated group.CONCLUSION: SPEE significantly inhibited HSC-3 cell proliferation in a concentration- and time-dependent manner, primarily by inducing G1-phase cell cycle arrest through the upregulation of p21 and p27. Taken together, SPEE could be a potential anti-cancer agent for tongue cancer cell. KEYWORDS: Stenochlaena palustris, tongue cancer, cytotoxic, cell cycle arrest, HSC-3 cells, p21, p27

Abstract

BACKGROUND: Curcuma xanthorrhiza rhizomes have been demonstrated to have anticancer properties toward various types of cancer cells. The effect of C. xanthorrhiza rhizome extract (CXRE) on nasopharyngeal cancer (NPC) cells, including HONE-1 cell line has not been elucidated yet. Therefore, the effect of CXRE on the apoptosis of HONE-1 cells and its possible underlying mechanism are necessary to be explored.METHODS: C. xanthorrhiza rhizomes were minced, dried, extracted with distilled ethanol, filtered, and evaporated to produce CXRE. HONE-1 cells were seeded, starved, and treated with dimethyl sulfoxide (DMSO), Doxorubicin, or various concentrations of CXRE. Treated HONE-1 cells were stained with 4',6'-diamidino-2-phenylindole (DAPI) and the number of viable cells was counted. HONE-1 cells were also collected, lysed, and further processed for immunoblotting analysis to measure Bid activity.RESULTS: The number of viable HONE-1 cells decreased in concentration- and time-dependent manner. The number of viable cells in 50 and 250 μg/mL CXRE-treated groups were significantly lower compared with that in the DMSO-treated group after 24 h. At 48 h incubation period, the number of viable cells in 10, 50 and 250 μg/mL CXRE-treated groups were significantly lower compared with that in the DMSO-treated group. The number of viable cells in 250 μg/mL CXRE-treatment group was not significantly different compared with that in the Doxorubicin-treated group after 48 h. Bid expression levels in CXRE-treated groups were lower compared with that in the DMSO-treated group.CONCLUSION: CXRE could induce apoptosis via Bid activation, hence reducing the viability of HONE-1 cells.KEYWORDS: Curcuma xanthorrhiza, nasopharyngeal cancer, HONE-1 cells, apoptosis, Bid

Abstract

Ameloblastoma, a tumor located in the jaw, grows slowly but locally invasive. Ameloblastoma expands in the jaw based on a mechanism resorbing the surrounding bone. To date, the bone resorption mechanisms of ameloblastoma are associated with the expression of receptor activator of nuclear factor (NF)-κB (RANK) ligand (RANKL), matrix metalloproteinases (MMPs), and tumor necrosis factor (TNF)-α. RANKL plays an important role in generating osteoclastogenesis. MMPs degrade the extracellular matrix. TNF-α can induce the formation of osteoclast and modulate the MMPs. In this review the bone resorption mechanism of ameloblastoma as well its signaling pathway will be disclosed.Keywords: Ameloblastoma, RANKL, MMPs, TNF-α.
