Abstract

Oral health faces significant challenges due to increasing dental infections by pathogenic microbes such as Porphyromonas gingivalis, Streptococcus mutans, and Candida albicans. Topical antioxidants in toothpaste, gel, and mouthwash are often used to treat dental diseases. There is a growing interest in finding natural alternatives for oral hygiene without side effects compared to conventional toothpaste formulations. Nigella sativa (black cumin) has various pharmaceutical efficacy, making it a valuable plant-based source medicinal compound. This study evaluated black cumin ethanol extract's (BCSE) antimicrobial and antioxidant activities. Antibacterial effectiveness was evaluated through Minimum Inhibitory Concentration (MIC), Minimum Bactericidal Concentration (MBC), and disc diffusion assays against P. gingivalis, S. mutans, and C. albicans. Antioxidant activity was reported based on DPPH scavenging, ABTS reduction, H2O2 scavenging, and NO scavenging assays. Black cumin seed ethanolic extract (BCSE) showed antibacterial activity of 4.49 mm, 4.33 mm, and 7.12 mm for P. gingivalis, S. mutans, and C. albicans, respectively, with zones of inhibition increasing in a concentration-dependent manner (p<0.05). MIC and MBC evaluations also revealed that MIC for S. mutans was achieved at 12.5% BCSE concentration, while P. gingivalis and C. albicans required 25%, and MBC reached 100%. The IC50 for DPPH, ABTS, NO, and H2O2 were 25.41, 69.93, 87.18, and 95.16 μg/ml, respectively. The antioxidant activity increased in a concentration-dependent manner, especially at 100 µg/ml of BCSE. Based on these results, BCSE could be an optional ingredient in toothpaste.

Abstract

The significant impact of stunting in early childhood affects both physical growth and cognitive development. The prevalence of stunting in Jungkat Village highlights the importance of monitoring growth and development during mid-childhood (ages 6-12), as it is a critical period for cognitive, social, and physical development. The study aims to provide insights into the effectiveness of interventions in addressing stunting by describing the body size and nutritional status of children aged 6-12 in Jungkat Village. A cross-sectional method was employed in four primary schools in Jongkat District. Anthropometric measurements of body height and body weight were used to calculate nutritional status indices, including the body height-to-age index and body mass index. In Jungkat Village, children aged 6-12 show varied growth patterns, including high rates of stunting and obesity, with some stunted children maintaining normal BMI for age, indicating complex interactions between nutrition and growth. In addition, there is no significant sexual dimorphism in growth patterns at this age, but differences in weight are evident, with boys generally heavier after age 7. Environmental, socioeconomic, and behavioral factors may significantly influence these patterns, underscoring the need for integrated health and nutrition interventions that target maternal and early childhood support.

Abstract

Cardiovascular diseases, including coronary heart disease and heart attack symptoms, are the leading causes of death worldwide. High cholesterol levels and blood sugar levels contribute significantly to these diseases. Therefore, this study aimed to determine the effectiveness of combining capsules of earthworm (Lumbricus rubellus) and cinnamon (Cinnamomum burmannii) in lowering cholesterol and blood sugar levels. After conducting pre-clinical trials, clinical trials were further carried out in humans. Cholesterol and blood sugar levels were measured for 14 days in Phases 1 and 2. Statistical data analysis was conducted using the Shapiro-Wilk normality test, paired t-hypothesis test, Wilcoxon test, and frequency analysis. The results showed that in Phase 1, there were significant differences in volunteers' cholesterol and blood sugar levels with no clinical symptoms. The most significant decrease in cholesterol levels in female volunteers occurred at the age of 21-30 years, at 25.56%, while the most significant reduction in blood sugar levels occurred at 41-50 years, at 41.50%. On the other hand, the most significant decrease in cholesterol levels in male volunteers occurred at the age of 41-50 years at 33.08%, and the most significant reduction in blood sugar levels occurred at the age of >60 years at 38.87%. The most significant content in the combination capsule was fatty acids and cinnamaldehyde. In conclusion, consuming a combination of earthworm and cinnamon capsules for 14 days caused a reduction in cholesterol and blood sugar levels.

Abstract

Quinoa (Chenopodium quinoa) is an ancient grain renowned for its remarkable nutritional value and remarkable adaptability to diverse environmental conditions, making it a valuable crop for enhancing food security. Understanding the molecular mechanisms triggering its development and stress responses is crucial for crop improvement. This study conducted a comprehensive analysis of the CONSTANS-like (CqCOL) transcription factors in quinoa, which play a pivotal role in photoperiodic flowering regulation. We identified and characterized 20 CqCOL genes, analyzing their physicochemical properties, phylogenetic relationships, gene structures, and promoter regions. Our findings revealed significant diversity among the CqCOL proteins and suggested potential functional specialization within the family. Promoter analysis uncovered various stress-responsive and phytohormone-responsive cis-regulatory elements, revealing that CqCOL genes may be associated with stress adaptation and hormonal signaling pathways. Transcriptomic analyses under different conditions supported these insights, highlighting the importance of CqCOL genes in quinoa's developmental processes and stress responses. Specifically, most CqCOL genes exhibited stable expression under heat stress, except CqCOL02 and CqCOL12, which were induced in roots by 1.85- and 1.91-fold, respectively. Under normal conditions, CqCOL01, CqCOL11, and CqCOL18 showed organ-specific expression, particularly in flowers and leaves, with no expression detected in roots. This study enhances our understanding of the CqCOL transcription factor family. It provides a foundation for future functional studies and breeding strategies aimed at improving stress tolerance and optimizing flowering time in quinoa.

Abstract

Sentul chicken is a local Indonesian chicken primarily raised for meat production. One crucial factor affecting egg quality and embryo development is hen age. This study aims to examine the influence of hen age on the external and internal quality of Sentul chicken hatching eggs, as well as the early development of the embryo. Eggs from 41-week-old and 78-week-old hens were compared across exterior and interior quality, nutrient composition, and embryonic development. Data analysis was performed using a descriptive method for hatching egg quality and a t-test for embryonic development. Results revealed that eggs from older hens (78 weeks) were significantly (P<0.05) heavier, had a higher egg shape index, and exhibited higher albumen and yolk indices, as well as a higher Haugh unit (HU). Nutrient analysis showed an increase in protein and fat content in older hens’ eggs, alongside a reduction in water content. However, embryonic development assessed by primitive streak and somite formation showed no significant differences (P>0.05) between the age groups. These findings highlight the positive influence of hen age on egg quality and embryonic development, potentially enhancing hatchability and chick development. Further research is, however, needed to observe long-term effects of hen age on embryo development and post-hatch performance.

Abstract

Beauty and health are currently topics of the global trend. Secondary metabolites from natural sources have become increasingly important for their potential application in cosmetics. This study aims to investigate the potential of Acriopsis liliifolia roots (ALR) as a source of active cosmetic ingredients through secondary metabolite profiling, in silico, and in vitro analysis. A. liliifolia, a medicinally valuable orchid species, was selected due to its rich phytochemical content, which could offer beneficial properties for skin, such as skin-brightening effects. The roots of A. liliifolia were subjected to microchemical assay and metabolite profiling using Liquid Chromatography High-Resolution Mass Spectrometry (LC-HRMS) to determine the bioactive compounds. Additionally, the identified compounds were evaluated through molecular docking studies to assess their interactions with key skin-related enzymes, such as tyrosinase. In vitro studies were conducted to confirm the activity of secondary metabolites of A. liliifolia root on the inhibition of tyrosinase. Microchemical results showed that ALR is positive for phenolics and alkaloids. Metabolite profiling revealed the presence of 125 compounds, then 14 of the most potential compounds were selected. The docking studies exhibit that 1,3-dilinolenoylglycerol had the lowest S-score of -9.54 kJ/mol and lower than kojic acid, suggesting that 1,3-dilinolenoylglycerol has the potential to inhibit tyrosinase. The in vitro studies showed that A. liliifolia roots extract at 250 mg/ml can inhibit tyrosinase (150 U/ml) by 42.56%. However, further research is required to ascertain its potential effect and safety assessment of cosmetics.

Abstract

Fine roots (≤2 mm diameter) are a plant organ that plays a major role in nutrient and water acquisition from the soil and a parameter for understanding belowground changes. Fine root traits can determine the plant's strategies in maximizing resource acquisition for productivity with an acquisitive strategy or maximizing resource investment with a conservative strategy. In this study, enrichment planting was carried out in oil palm plantations through a combination of oil palm and tree crops. It is necessary to determine whether enrichment planting can impact the nutrient and water acquisition of oil palm fine roots. Therefore, this study aimed to determine the nutrient and water acquisition strategies of oil palm fine roots enriched with crop species by analyzing differences in morphological traits through fine root inventory. The enrichment planting treatments were R0 (plot of oil palm without enrichment crop), R1 (plot of oil palm with one crop), R2 (plot of oil palm with two crops), R3 (plot of oil palm with three crops), and R6 (plot of oil palm with six crops/multispecies). The results showed that enrichment planting in oil palm plantations can be practiced with two and three crop species, as in plots R2 and R3, which support a conservative strategy with high RTD (root tissue density) and low SRL (specific root length) and SRA (specific root area) in oil palm fine roots. In contrast, high species diversity in plot R6 triggered a shift to an acquisitive strategy with high SRL and SRA and low RTD.

Abstract

The genus Periophthalmus (Bloch and Schneider, 1801) comprises a diverse group of mudskippers within the family Oxudercidae and subfamily Oxudercinae. It includes 20 verified species globally, with 11 of these species originating from Indonesia. Among them, P. kalolo and P. argentilineatus are prevalent across seven major islands. However, P. novemradiatus is less documented, with limited distribution records. The morphological similarities among Periophthalmus spp. complicate recognition, often leading to misidentification. To address this challenge, this study investigated the phylogenetic relationships and genetic diversity among these three species, utilizing the 16S rRNA gene as a marker. PCR amplification of the DNA from samples collected from seven regions along Java's southern coast employed primers 16Sar and 16Sbr. Phylogenetic analysis revealed three monophyletic clades corresponding to each species, with genetic divergences ranging from 3.66 to 5.40%. P. argentilineatus displayed a relatively high intraspecific divergence of 0.21-2.26%, suggesting the potential identification of cryptic species within this lineage, even with a conserved gene like 16S rRNA. We identified 47 variable sites within the 552-bp 16S rRNA sequence, including four singleton sites and 43 parsimony-informative sites. We discovered a unique marker at position 172 that could serve as a genetic identifier for distinguishing these species. These findings suggest that the 16S rRNA gene has potential as an alternative marker for species identification while also revealing genetic diversity, thereby complementing or even serving as an alternative to the commonly used COI gene in Periophthalmus spp.

Abstract

This study evaluates the effect of lighting and cell inoculum in Spirulina platensis cultivation on its growth, pigment composition, and ability to capture CO2. Different light intensities (1,000, 3,000, and 5,000 lux), light quality (white, blue, and red), and cell inoculum which are shown as OD values (0.2, 0.3, and 0.5) were assessed. The highest growth rate was obtained from red light, followed by white and blue light. The maximum biomass concentration (0.0711 mg/ml) was obtained when red light was used under 5,000 lux light intensity. The highest carbon content (5.1274 mg/ml algae) was also obtained during red light cultivation under 5,000 lux light intensity. Meanwhile, the highest chlorophyll (1.4365 mg/mg algae) content was obtained at blue light cultivation under 5,000 lux intensity and OD 0.5 cell inoculum. The highest phycocyanin (0.0309 mg/mg algae) was obtained under red light with 3,000 lux light intensity and OD 0.5 cell inoculum. It was found that the cultivation conditions to achieve high biomass and high pigment concentration were different.

Abstract

The prevalence of antibiotic-resistant bacteria is increasing every year in Indonesia. This resistance occurs in several antimicrobial categories. A contributing factor to microbial resistance is the capacity of microbes to develop biofilms. Amo.128 is an actinomycete from the Laboratory Biotechnology, BRIN Serpong collection, which is expected to have both antimicrobial and antibiofilm activity. This study aimed to identify amo.128 macroscopically, microscopically, and molecularly; to determine the antibacterial and antibiofilm activity; to identify secondary metabolites; and to understand the mechanism of quorum sensing inhibition by in silico with proteins targeting SdiA and AgrA. Based on macroscopic and microscopic observations, the amo.128 isolate belongs to the genus Streptomyces. Phylogenetic analysis of the amo.128 isolate is 100% similar to Streptomyces parvus strain NBRC 14599. The amo.128 metabolite contains several compounds, including N-acetyltyramine, cyclophenylalanylprolyl/cFP, and the pyrrole-pyrazine group. The MIC/MBC/MIC50 value of the amo.128 metabolite against Staphylococcus aureus is 25/50/28.48 ppm, while for Escherichia coli it is 100/200/49.38 ppm. The amo.128 metabolite reduced biofilms formed by S. aureus and E. coli with BRC50 values of 62.07 ppm and 60.44 ppm, respectively. The amo.128 metabolite compound, cyclophenylalanylprolyl/cFP, has potential activity as a quorum-sensing inhibitor.
