Abstract

Free radicals can cause various diseases in the body if not treated immediately. Large levels of free radicals may trigger damage to normally functioning tissues, lipid layers, blood vessels, DNA synthesis disturbances, and even destruction of cells. The objective is to evaluate the antioxidants potential of dayak onion extract and fractions. FTIR spectrophotometers, gas chromatography-mass spectrometry (GC-MS) and an antioxidants multimode reader are some of the research methods. The outcomes of this research are identifying plants that showed the dayak onion extract of the species Eleutherine Americana Merr. It contains compounds such as flavonoids, alkaloids, tannins, and saponins. In addition, the components found in the extract, water fraction, ethyl acetate fraction, and n-hexane fraction are octadecanoic acid 298 m/z, 9-octadecanoic acid 282 m/z, undecanoic acid 214 m/z, hexadecanoic acid 368 m/z, and nonadecanoic acid 326 m/z. Therefore, the antioxidants test using the DPPH method showed that the best IC50 value is for ethyl acetate with IC50 20.56 ppm.

Abstract

Preventing the spread of nosocomial infection are generally carried out by disinfection process of the tools to be used with chemical disinfectant such as phenol, alcohol, chlorine, iodine or sublimate. Excessive use of chemicals can cause health problems. Guava leaves (Psidium guajava L.) have long been empirically used to treat diarrhea and acne. Scientific data shows that guava leaves have positive activity against several types of pathogenic bacteria due to its tannin content. Guava leaves have the potential to be developed as a disinfectant and antiseptic material. This study aims to determine the disinfection activity of guava leaves on surgical instruments using the total plate count method, skin irritation test using patch test method and quantify the tannin content in young and old guava leaves using spectrophotometry method. The results showed that the tannin content in old and young guava leaves was 68.73 ± 0.067 mg/g (6.873%) and young 61.87 ± 0.046 mg/g (6.187%). At concentrations of 10, 20, 30 and 40% guava leaf extract were able to reduce the total plate count in surgical instrument samples by 6.85; 37; 80.82; and 83.56%. The primary irritation index of 0.05 only occurs at a concentration of 40%, classified as non-irritant. It can be concluded that guava leaves have the potential to be further developed as a natural disinfectant or antiseptic.

Abstract

Increasing demand for Virgin Coconut Oil (VCO) presents a promising opportunity to improve the economy in Indonesia. Various methods for VCO production have been explored to optimize yield and ensure desirable organoleptic and physicochemical qualities. Modifying the oil extraction process often necessitates costly equipment. In this study, VCO was extracted by combining the chilling-thawing method with the addition of lactic acid bacteria (LAB) isolated from blondo. The process began with the isolation and characterization of LAB isolates, followed by the application of the chilling-thawing method and addition of 2% LAB starter, then assessed for their consumer preference through a questionnaire. This innovative process yielded VCO at a rate of 35.78-46.65% using three LAB isolates (BAL 1-3) from blondo samples, representing an improvement over previous studies employing similar methodologies. Moreover, hedonic evaluation revealed a higher consumer preference for LAB-treated VCO compared to the control, further highlighting the effectiveness of LAB treatment in combination with the chilling-thawing method.

Abstract

The Stachytarpheta jamaicensis (L) Vahl root contains bioactive compounds like saponins, alkaloids, flavonoids, tannins, phenols, and terpenoids, which have antibacterial and anti-inflammatory properties. This study investigates the wound healing effects of Stachytarpheta jamaicensis (L) Vahl root extract gel in oral mucosa. The experiment involved 28 male Wistar rats, divided into four groups: a positive control treated with povidone iodine 10%, a negative control treated with gel base, and two experimental groups treated with 6% and 10% S. jamaicensis root extract gels. The gel was applied twice daily, and wound healing was assessed by epithelial thickness, inflammation cell and hydroxyproline content. Both concentrations of S. jamaicensis root extract gel significantly enhanced wound healing, as shown by increased epithelial thickness, inflammation cell and hydroxyproline content levels compared to the negative control. These findings suggest that S. jamaicensis root extract gel effectively promotes wound healing in the excision wound model.

Abstract

Multi-drug resistant tuberculosis (MDR-TB) is caused by Mycobacterium tuberculosis strains that resist at least two first-line anti-TB drugs. This disease presents a major global health challenge, particularly affecting middle to lower income countries where affordable and rapid diagnostic tools are urgently needed. To address this, researchers are exploring the combination of whole genome sequencing and machine learning for drug resistance predictions. Using Mycobacterium tuberculosis genomic data from databases, both Logistic Regression (LR) and Convolutional Neural Network (CNN) models were trained to predict drug resistance. Performance evaluation revealed that CNN slightly outperformed LR in accuracy and specificity for Rifampicin and Pyrazinamide predictions, while LR showed better results for Isoniazid and Ethambutol. In terms of sensitivity, LR demonstrated superior performance for most drugs, except Ethambutol where CNN excelled. Though computational complexity assessment was incomplete due to hardware limitations, both models showed distinct advantages in predicting first-line anti-TB drug resistance.

Abstract

One factor that affects frozen semen characteristics is bull age. Increasing age induces changes in sperm that reduce frozen semen quality. This study aimed to evaluate the frozen semen characteristics of Bali bulls aged 3, 8, and 13 years. Frozen semen was derived from fresh semen with sperm motility > 70%. The frozen semen characteristics tested included motility, viability, plasma membrane integrity, acrosome integrity, and sperm abnormalities. Sperm motility was analyzed by computer-assisted sperm analysis (CASA). Viability was assessed using eosin-nigrosin staining; plasma membrane integrity was assessed using the hypoosmotic swelling test (HOST); acrosome integrity was assessed using Giemsa staining; and sperm abnormalities were assessed using Williams staining. The plasma membrane integrity of the 13-year-old group was significantly lower (P < 0.05) than that of the younger age groups. However, there were no significant differences (P > 0.05) in the other parameters. We conclude that age affects the integrity of the sperm plasma membrane in frozen semen from Bali bulls.

Abstract

Efficient nitrogen use is crucial for maximizing oil palm yield while reducing environmental impact. Poor nitrogen utilization causes excessive growth and nutrient loss. This study uses bioinformatics to identify key genes linked to nitrogen use efficiency, providing insights for genetic improvement and sustainable cultivation.Protein-protein interaction (PPI) networks, functional enrichment, and structural modeling were employed to uncover candidate genes regulating nitrogen uptake and metabolism. Sixty-two nitrogen use efficiency associated genes from rice (Oryza sativa) were analyzed via BLASTp against the E. guineensis genome (NCBI), selecting those with >80% similarity. PPI networks were constructed using STRING-db and analyzed in Cytoscape v3.7.1. Functional enrichment (Gene Ontology) and structural analysis (AlphaFold, PyMol v2.5.4) were performed. Twelve nitrogen use efficiency related genes were identified, with CESA4, CESA7, and CESA9 emerging as key regulators based on high degree and betweenness values in PPI analysis. These genes are linked to plant cell wall biosynthesis. Structural analysis showed high similarity to rice homologs, with RMSD values of 0.338 Å (CESA4) and 0.396 Å (CESA9), indicating strong conservation area. Their structural relevance suggests they are promising targets for molecular breeding marker to enhance nitrogen utilization and sustainability in oil palm.

Abstract

Sepsis is an irregular body response to severe infection, triggering uncontrolled inflammation that can lead to extensive tissue damage. It can progress to septic shock with multiple organ failure, resulting in death if left untreated. Laboratory examinations, such as leukocyte differential count in hematology, help understand the distribution pattern of white blood cells associated with health conditions. Laboratory research was conducted on mice injected with E. coli ESBL or K. pneumoniae carbapenemase. After 24 hours, observations were made on apoptosis in the spleen and liver of mice. Mouse blood was processed to count white blood cell types with a differential count. The results were analyzed to compare the control group with the bacterial infection groups of E. coli ESBL and K. pneumoniae carbapenemase. The research results indicate that the neutrophil count in the E. coli ESBL group is still within the normal range and lower (44.5±1.915%) compared to the K. pneumoniae carbapenemase group (55.75±8.342%). Similarly, the lymphocyte count in the E. coli ESBL group is within the normal range and lower (77.5±3.109%) compared to the K. pneumoniae carbapenemase group (91.25±7.588%). This highlights the crucial role of neutrophils and lymphocytes in responding to severe bacterial infections such as K. pneumoniae carbapenemase. Previous studies indicate neutrophilia and lymphocytopenia as markers of severe bacterial infections. Neutrophils are the primary defense against bacterial infections and can be rapidly recruited to the infection site, while specific infections can trigger prolonged neutrophil recruitment from hematopoietic tissues.
