Abstract

The textile industry is a major contributor to global water pollution, releasing an estimated 280,000 tons of synthetic dyes annually into aquatic ecosystems. These dyes, particularly azo compounds, are often toxic, mutagenic, and resistant to conventional wastewater treatment methods. Microbial enzymatic degradation, especially by white-rot fungi, offers a promising eco-friendly alternative. This study aimed to optimize the production of ligninolytic enzymes—Laccase (Lac), manganese peroxidase (MnP), and lignin peroxidase (LiP)—from Coriolopsis caperata, and assess their efficiency in degrading two azo dyes: Reactive Red 21 (RR21) and Reactive Orange 107 (RO107). The fungus, isolated from the Peat Swamp Forest in Sebangau, Central Kalimantan, was cultured in a modified glucose-peptone medium enriched with veratryl alcohol. The optimization parameters included variations in time, dye concentration, and the addition of hydrogen peroxide (H₂O₂). Enzyme activity was quantified spectrophotometrically, and dye decolorization was assessed over time at different dye concentrations. Among the enzymes, Lac showed the highest activity (4938.05 U/L), followed by LiP (995.26 U/L) and MnP (246.47 U/L). These values notably exceed several previously reported benchmarks for fungal enzyme activity. RO107 demonstrated greater susceptibility to enzymatic degradation, with 83.71% decolorization achieved at 24 hours, while RR21 reached 65.71% at 48 hours. The addition of 1 mM H₂O₂ significantly enhanced decolorization, increasing RR21 and RO107 removal to 95.71% and 99.30%, respectively. These results underscore the oxidative synergy between H₂O₂ and ligninolytic enzymes, particularly LiP and MnP. Overall, the study demonstrates the potential scalability of C. caperata-based enzymatic treatment systems for textile effluent bioremediation, supporting compliance with environmental discharge regulations and contributing to sustainable wastewater management.

Abstract

Macrozoobenthos are effective bioindicators for assessing freshwater ecosystem health. This study examines the influence of physicochemical parameters and spatial-temporal variation on macrozoobenthic abundance in the Kungkilan River, South Sumatera. Sampling was conducted at upstream, midstream, and downstream sites. Generalized Linear Mixed Model (GLMM) analysis revealed that water depth and transparency had significant positive effects, while iron (Fe) in sediment had a negative effect. Random effects analysis showed that site-level variability (variance = 0.680) was far greater than temporal variability, indicating that spatial differences—especially in the midstream zone—were the dominant drivers of community structure. These findings highlight the importance of localized conservation efforts and reinforce the role of macrozoobenthos as reliable indicators of river health in tropical ecosystems.

Abstract

This study was conducted to analyze the effect of post-production storage time on antioxidant activity in soy milk. Antioxidants are compounds that can ward off free radicals, so it is important to know their stability over time. The storage time used in this study was 1, 4, 7, 10, and 13 hours post-production. Antioxidant activity testing was carried out using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. Qualitatively, the color change of the DPPH solution was observed from purple to light yellow, while quantitatively the absorbance value was measured using UV-Vis Spectrophotometry. The inhibition value and IC50 were calculated to determine the strength of antioxidant activity in soy milk. The results showed that soy milk with a storage time of 1 hour had the best antioxidant activity with an IC50 value of 28.19 μg/ml which was classified as very strong. At 4 hours of storage time, the IC50 value of 37.28 μg/ml is classified as moderate, while at 7 hours and 10 hours the IC50 values ​​were 146.95 μg/ml and 119.38 μg/ml, respectively, which are also classified as moderate. At 13 hours, the antioxidant activity decreased drastically with an IC50 value of 228.90 μg/ml, which is classified as very weak. The antioxidant activity of soy milk decreased with increasing storage time. Factors such as temperature, light, and components of soy milk contribute to the degradation of antioxidant activity. Therefore, consumption of soy milk should be done within a shorter time after production to obtain optimal antioxidant benefits.

Abstract

Zinc is a vital micronutrient involved in various reproductive processes in cattle. This review aims to evaluate the effects of zinc supplementation on cattle reproductive performance by analyzing research articles sourced from Scopus and PubMed databases. Findings indicate that zinc supplementation, provided in either organic or inorganic forms, positively influences reproductive parameters. In bulls, zinc enhances sperm motility, viability, and ejaculate volume. In female cattle, supplementation modulates endocrine hormone levels during both pre-calving and post-calving periods. Moreover, appropriate zinc dosages and supplementation durations contribute to improved reproductive efficiency in cows. These results support the conclusion that zinc supplementation is effective in enhancing reproductive performance in cattle.

Abstract

This study aimed to evaluate the effect of different vitamin C concentrations (0, 0.1, 0.2, and 0.3 g/100 mL) in egg yolk citrate extender and storage time (0, 24, 48, 72, and 96 hours) on the quality of Bangkok rooster semen stored at 5°C. Using a split-plot-in-time design with four replications, semen quality was assessed for motility, viability, abnormality, intact plasma membrane (IPM), and longevity. Results showed a significant interaction (P<0.01) between vitamin C concentration and storage time on motility, and significant effects (P<0.05) on viability, abnormality, and IPM. The 0.2 g vitamin C dose preserved >40% motility and >50% viability for 96 hours and extended sperm longevity up to 11.25±0.95 days. These findings suggest that 0.2 g/100 mL vitamin C is the optimal concentration for preserving rooster semen quality during short-term cold storage.

This study aimed to evaluate the quality and kinematics of spermatozoa in fresh and frozen semen of coastal cattle. Semen of coastal cattle was collected using an artificial vagina from 2 males, fresh semen was tested and frozen using tris egg yolk diluent. Fresh and frozen semen of coastal cattle were evaluated using a Computer Assisted Sperm Analyzer (CASA). This study used a t-test analysis by comparing the quality and kinematics of spermatozoa of fresh semen and frozen semen of coastal cattle. The parameters observed were macroscopic, microscopic and CASA quality observations. The results showed the kinematics of fresh and frozen semen motility (83.83%; 71.68%) and the kinematics of progressive motility of fresh and frozen semen (80.81%; 59.56%). Based on the results of the t-test analysis, it was found that t count > t table, the kinematics of fresh semen spermatozoa had a significant effect on the frozen semen of Pesisir cattle on the motility of fresh semen and frozen semen, on the progressive motility of fresh semen and frozen semen. The characteristic values ​​of kinematics in fresh semen and frozen semen of Pesisir cattle were respectively velocity curvilinear (VCL) 178.94 μm/s and 108.52 μm/s; velocity straight line (VSL) 96.61 μm/s and 49.34 μm/s; velocity average path (VAP) 114.99 μm/s and 64.04 μm/s; linearity (LIN) 0.53% and 0.44%; straightness (STR) 0.83% and 0.75%; wobble (WOB) 0.64% and 0.58%; lateral head displacement (ALH) amplitude 5.83 μm and 5.15 μm; beat cross frequency (BCF) 35.28 Hz and 24.65 Hz. The kinematics of fresh and frozen semen spermatozoa significantly affect the value of motility characteristics. The conclusion of the results of this study is that there is a decrease in the quality of fresh semen kinematics and frozen semen kinematics spermatozoa on the value of motility characteristics, namely on the speed of spermatozoa at the velocity curvilinear (VCL), velocity straight line (VSL), and velocity average path (VAP), linearity (LIN), straightness (STR), and wobble (WOB) and on the distance value of spermatozoa amplitude lateral head displacement (ALH) and beat cross frequency (BCF).

Abstract

The salivary glands of mosquito vector diseases contain various biological components which facilitate blood-feeding into the host's body. These components are mostly protein molecules. Numerous protein molecules in the salivary glands have gained substantial research emphasis to determine their role and function, including those in the salivary glands of Ae. albopictus. D7 protein is the main component in Aedes salivary glands, which aids in inhibiting platelet aggregation by binding to the Thromboxane A2 (TxA2) during the blood-feeding. TxA2 is a eicosanoid molecule that stimulates platelet aggregation. The protein's ability to bind TxA2 shows that this protein has potential as a new antiplatelet agent. The examination of the D7 protein in binding TxA2 was performed through an in-silico approach using the molecular docking method. This research included selecting the 3D model of the D7 protein and the TxA2 ligand, preparing the 3D model of the D7 protein, native ligands, and test ligands, targeted molecular docking method, validating the molecular docking, analysis and visualization of the docking results. The molecular docking validation shows an RMSD value of 1.657 Å. The results of molecular docking show an ΔG value of -5.60 kcal/mol, meaning that the D7 protein can bind to the TxA2 ligand stably and spontaneously. The active site of the D7 protein in binding the TxA2 ligand consists of several amino acid residues, namely THR 190, GLU 268, TYR 178, PHE 154, ILE 175, ARG176, VAL 293, TYR 248, and TYR 178. The ability of D7 protein to bind TxA2 as an inducer of platelet aggregation has demonstrated its potential as a novel antiplatelet agent. These results can pave further development of drug discovery in the medical and pharmaceutical fields.

Abstract

Colorectal cancer (CRC) remains a leading cause of cancer-related deaths worldwide, with limited effective therapies due to drug resistance and adverse effects. Zerumbone, a sesquiterpene isolated from Zingiber zerumbet Smith, has emerged as a promising natural anticancer agent. This review examines zerumbone's anti-colorectal cancer properties, including induction of apoptosis and cell cycle arrest, inhibition of invasion and metastasis, anti-angiogenic activity, and anti-inflammatory effects. Additionally, zerumbone demonstrates antioxidant properties, modulates gut microbiota composition, and targets multiple signaling pathways involved in CRC pathogenesis. Structure-activity relationship studies reveal the critical role of the α,β-unsaturated carbonyl group in its bioactivity. Despite promising preclinical evidence, clinical validation remains necessary to establish zerumbone's therapeutic potential for colorectal cancer management.

Abstract

Operational implementation, such as laboratory staff and equipment, differ for each frozen semen producer, resulting in variability in the quality assessment of the frozen semen produced. Conventional assessments subject to subjectivity, human error, and high variability. Computer-assisted semen analysis (CASA) is considered more objective. This study aimed was to conduct a comparative analysis of motility and concentration assessment of frozen semen sperm using conventional and the portable CASA AndroScope. Twenty-one laboratory assistants from 21 national and regional frozen semen producers participated in this study. Sperm motility and concentration were assessed conventionally (using a Neubauer chamber) and AndroScope was used with five replicates. The results of the comparison of sperm motility scores revealed significant differences (p<0.05) between conventional examination and using AndroScope. The results of the comparison of the sperm concentration calculations revealed no significant difference (p>0.05) between the calculations performed using the Neubauer chamber and AndroScope. Assessment with the AndroScope is considered reliable and can replace conventional assessment in assessing motility and sperm concentration, thereby improving and standardizing the assessment performed by frozen semen producers.
