Abstract

Excessive fat consumption, especially saturated and trans fatty acids, plays a significant role in metabolic disorders such as obesity, dyslipidemia, and cardiovascular disease through increased oxidative stress. Malondialdehyde (MDA), the end product of lipid peroxidation, serves as a biomarker of oxidative damage, whereas indirect bilirubin acts as an endogenous antioxidant. This study aimed to evaluate the effect of fragrant pandan leaves ethanol extract (FPLEE) in reducing MDA levels and modulating indirect bilirubin activity in rats fed a high-fat diet (HFD). The experimental method used 24 male Rattus norvegicus divided into six treatment groups: normal control (NC), positive control (C+), negative control (C-), and three FPLEE treatment groups with different doses (8, 16, and 32 mg/200 g BW/day). Administration was carried out for 14 days after 14 days of HFD induction. MDA levels were measured using the ELISA method, while total bilirubin and direct bilirubin were measured using spectrophotometry to determine indirect bilirubin levels. Statistical analysis was performed using one-way ANOVA and the post hoc Bonferroni test. The results showed that there were no significant differences in MDA levels between groups, although the C+ group fed a HFD showed a tendency toward increased MDA. Indirect bilirubin levels increased significantly in the low-dose FPLEE group (8 mg/200 g BW/day), indicating increased endogenous antioxidant activity, while higher doses did not. Thus, FPLEE has the potential to be an effective natural phytopharmaceutical agent in enhancing the body's antioxidant defence against oxidative stress caused by excessive fat consumption, especially at low doses.

Abstract

Stunting defined as impaired linear growth resulting in a child’s height falling below the age-appropriate standard, remains a pressing global health concern due to its long-term implications on development and increased risk of mortality. In Gorontalo Province, Indonesia, the prevalence of stunting exceeds the national target of 23.8%, with North Gorontalo Regency reporting the highest rate at 29.3%. This study aimed to examine the effect of toddler massage on weight gain among stunted children. A quasi-experimental design with a pretest-posttest control group approach was employed, involving 32 stunted toddlers selected through purposive sampling. Participants were equally allocated into an intervention group (n=16), which received toddler massage based on standard operating procedures, and a control group (n=16), which did not receive the intervention. Body weight was measured using digital scales. The results of the paired t-test revealed a statistically significant weight gain in the intervention group (p = 0.00), whereas no significant difference was observed in the control group (p = 0.164). The findings indicate that toddler massage may contribute to weight improvement in stunted children and could be considered a supportive non-pharmacological intervention in stunting management programs.

Abstract

Favipiravir is a type of RNA-dependent RNA polymerase (RdRp) inhibitor. Favipiravir is converted by host enzymes to T-705-ribofuranosyl 5-triphosphate and may act as a nucleotide analogue that selectively inhibits viral RNA-dependent RNA polymerase or causes lethal mutagenesis upon insertion into viral RNA without cytotoxicity in mammalian cells. Oseltamivir is part of the neuraminidase inhibitors (NAIs) group which has a mechanism of action by inhibiting viral neuraminidase. Most of the alternative therapies for Covid-19 require pharmacoeconomic studies, especially regarding cost-effectiveness analysis which is useful in balancing patient expenses by determining treatment alternatives that represent the best health outcomes at a more affordable cost. The aim of this study was to compare the cost effectiveness of the antiretrovirals Favipiravir and Oseltamivir. This research method used a descriptive analytic cross-sectional design and data collection was carried out retrospectively from the medical records of Covid-19 sufferers while detailed data on medical expenses were obtained from the finance department of inpatients at Cisarua Pulmonary Hospital, Bogor for the period September-October 2022. Sample of 80 patients consisted of 40 patients using Favipiravir and 40 patients using Oseltamivir. The parameters used in this research are direct medical costs (which include doctor visit costs, treatment room costs, laboratory costs and drug costs) while the effectiveness uses a negative RT PCR value. The results showed that in patients using Favipiravir with an average length of treatment 6.525 days, the total cost was Rp. 9,930,327/patient and Cost-Effectiveness Ratio (RP/day/patient) Rp. 1,521,899.195, whereas in patients using Oseltamivir with an average length of treatment 7.925 days, the total cost was IDR. 12,368,397/patient and Cost-Effectiveness Ratio (Rp/day/patient) IDR. 1,560,681,009. It can be concluded that Favipiravir is more cost effective than Oseltamivir.

Abstract

Soursop leaves (Annona muricata) are known as a plant that has the potential to treat breast cancer, which has a high mortality rate in women in Indonesia. The receptor that plays the most important role in breast cancer development is the Estrogen Receptor Alpha (ERa). This study aims to identify active compounds in soursop leaves that have the potential to inhibit breast cancer cell growth through in silico analysis using molecular docking of the ER? receptor using KNApSAck, PASS Online, PubChem, PDB ID, PyRx, and Discovery Studio software and Histochemical analysis was performed using fresh soursop leaves by making an incision on the lower part of the leaf and adding reagents AlCl, FeCl, Na2CO, CuSO4, glycerin, Wagner reagent, immersion oil, and ethanol, then observed microscopically. The in silico results showed the presence of specific compounds from soursop leaves and one reference compound (OHT600). Cis-Solamin had the highest binding affinity (-9.3 kcal/mol), better than the native ligand (-7.6 kcal/mol), and interacted with the amino acid Glutamine 532 (GLU532). Histochemical analysis showed the content of flavonoids, phenols, tannins, terpenoids, and alkaloids, accompanied by color changes in trichome and stomatal tissues. Based on the research data, it was concluded that soursop leaves can inhibit the growth of breast cancer cells through the content of secondary metabolites that actively inhibit Er? receptors.

Abstract

Stunting is a serious health problem among toddlers, characterized by delayed physical growth due to inadequate nutrition, a history of infectious diseases, low maternal education, and suboptimal parenting. In North Lombok Regency, the prevalence of stunting remained high at 19.3% in 2023. Efforts to address this issue have not only focused on nutritional interventions but also included complementary non-pharmacological therapies, such as melongas massage, which has been traditionally practiced using pucuk jarak and bedak langeh remedies. This study aimed to examine the effectiveness of these two remedies on the growth and development of stunted toddlers. A quasi-experimental nonequivalent control group design was applied, involving 72 stunted toddlers divided into three groups: pucuk jarak, bedak langeh, and control. The intervention was carried out for four weeks with melongas massage administered twice weekly. The measured parameters included body weight, height, appetite, sleep quality, and immune function. The results showed that the pucuk jarak group experienced more significant improvements across all parameters compared to the bedak langeh and control groups. Phytochemical tests supported these findings, showing total flavonoid levels of 53.32 mgQE/g in pucuk jarak compared to 3.58 mgQE/g in bedak langeh. The high flavonoid content is believed to play an important role in improving metabolism, appetite, growth, and immunity in toddlers. Thus, melongas massage using pucuk jarak has the potential to serve as a complementary strategy rooted in local wisdom for accelerating stunting reduction programs in North Lombok.

Abstract

SCOBY (Symbiotic Culture of Bacteria and Yeast) results from symbiosis between yeast and bacteria during fermentation. SCOBY kombucha gel combined with orange peel extract has antibacterial compounds that can inhibit the growth of S. aureus bacteria. The method in this study was to make variations in the concentration of SCOBY in the gel and inject S. aureus bacteria into the ears of mice. After 2x24 hours, the diameter of the inflammation caused was observed and SCOBY kombucha gel was applied (0%, 2%, 4%, 8%, 10%, and 12%), positive control (Mediclin 1%), and negative control (without gel application). The results showed that the higher the concentration of SCOBY, the faster the healing activity of the gel against S. aureus. SCOBY kombucha gel has the fastest healing activity in inhibiting acne pathogen S. aureus 12% SCOBY gel. Inflammation in the ears of mice treated with 12% SCOBY gel had healed by the 90th hour, while in other groups of mice it had only healed at the last observation hour, namely the 114th hour.

Abstract

Diabetes, a rapidly escalating global health challenge, is defined by chronic hyperglycemia resulting from impaired insulin secretion, impaired insulin action, or both. Current treatment options often fall short due to side effects and limited efficacy in addressing long-term complications, underscoring the urgent need for safer, more effective alternatives. This study delves into the potential of insulin-like compounds derived from bitter melon (Momordica charantia) to combat diabetes by targeting two pivotal proteins: glycogen synthase kinase-3 (GSK-3) and insulin receptors. These proteins are crucial for glucose regulation and insulin signaling, making them key targets for blood sugar control. Through computational molecular docking, we evaluated the binding affinities and inhibition potentials of key bitter melon compounds, including Charantin and Vicine. Molecular structures were sourced from the PubChem database and optimized using density functional theory (B3LYP functional, 6-311G++ (d, p) basis set) with Gaussian-09 software. Structural data for GSK-3 (PDB ID: 1Q5K) and insulin receptors (PDB ID: 1IR3) were retrieved from the Protein Data Bank, and docking studies were conducted using the Lamarckian genetic algorithm in AutoDock 4.2. Protein-ligand interactions, bond lengths, and amino acid residues in binding pockets were analyzed with Discovery Studio, while ADMET profiles and toxicity levels were predicted using pkCSM and ProTox-II.Charantin demonstrated the highest binding affinity and inhibition potential against both GSK-3 and insulin receptors. Toxicity analysis revealed that Charantin, classified under toxicity class 6, is safer than Vicine (class 4), with a higher LD50 value indicating lower toxicity. These findings position Charantin as a promising multi-target anti-diabetic agent with significant efficacy and minimal side effects. This research paves the way for developing novel, safer anti-diabetic medications derived from natural sources, offering a beacon of hope in the fight against diabetes.

Abstract

Biodegradable films made from natural materials such as cellulose and carrageenan are easily degradable but exhibit poor mechanical properties. Incorporating carbon nanodots (CDs) from cocoa husk waste has the potential to improve their mechanical properties. This study aimed to characterize CDs synthesized from cocoa husk waste and evaluate their mechanical properties of cellulose-carrageenan-based biodegradable films. The research stages include the isolation of cocoa husk cellulose, CDs synthesis, CDs characterization, biodegradable film preparation, and characterization of the mechanical properties of biodegradable films. The experimental design used was a Completely Randomized Design (CRD) with the treatment factor of CDs addition at six levels (0%, 1%, 3%, 5%, 7%, 9%) with three replicates. The results showed that the average size of cocoa husk CDs was 997 nm, and the absorbance peak was detected at 298 nm, validating that the CDs had been successfully synthesized with blue light emission. Incorporating CDs significantly affected the mechanical properties of the biodegradable film. Biodegradable cellulose-carrageenan-based films with the addition of CDs from cocoa husks had a thickness of 0.35–0.64 mm, tensile strength of 2.94–4.20 MPa, elongation of 36.51–63.28%, and elasticity of 6.00–9.45 MPa. The tensile strength and elongation values meet the JIS Z 1707 standard. Higher concentrations of CDs significantly improved tensile strength and elasticity, while reducing the thickness and elongation.
