Abstract

This work investigates the anticancer potential of silver nanoparticles (AgNPs) against T47D cells as well as the stability of AgNPs manufactured using extract from Acalypha indica L. used as a bioreductant. The plant extract was used to produce and stabilize AgNPs, and stability was tracked for 30 days using UV-Vis spectroscopy and Particle Size Analysis (PSA), which included evaluations of extended sun exposure. Transmission Electron Microscopy (TEM) was used to characterize the size and shape of the nanoparticles, and Fourier Transform-Infrared Spectroscopy (FT-IR) was used to determine which functional groups were responsible for stabilization. Despite a gradual size increase, the AgNPs remained stable throughout the study period. The MTT assay confirmed their potent cytotoxicity against T47D cells, underscoring the potential of Acalypha indica-derived AgNPs as stable and effective agents for cancer therapy, offering a promising alternative for novel anticancer treatments.

Abstract

Chronic kidney disease (CKD) is a global health challenge affecting over 800 million people worldwide. Early detection is crucial to prevent progression to end-stage renal disease (ESRD), where life-saving interventions like dialysis or transplantation are necessary. Among the markers for early kidney damage, the Albumin Creatinine Ratio (ACR) in urine is one of the most reliable. Conventional methods of ACR detection, such as LC/MS-MS and ELISA, are highly accurate but require expensive equipment and skilled personnel, limiting their accessibility, especially in resource-limited settings. To address this, we developed a 3D-connector microfluidic paperbased analytical device (3D-µPADs) enhanced with gold nanoparticles (AuNPs) for sensitive and low-cost ACR detection. The integration of AuNPs amplifies colorimetric signals, enhancing the visual distinction in albumin detection. Our 3D-µPADs werefabricated using chromatographic paper Whatman No. 1 with hydrophobic barriers created by solid wax printing, followed by reagent immobilization for albumin and creatinine detection. The colorimetric and distance responses, based on reactions with Bromocresol Green (BCG) and Chrome Azurol S-Palladium (CAS-Pd2+), were analyzed using ImageJ software to quantify albumin and creatinine levels. The 3D-µPADs exhibited optimal sensitivity and accuracy, with linear detection ranges for albumin and creatinine of 30–400 mg/g. Validation with human urine samples demonstrated an accuracy of 93.04%, suggesting that 3D-µPADs offer a promising alternative for early nephropathy detection. Our findings provide a cost-effective, accessible tool for CKD screening, potentially transforming diagnostics in low-resource environments.

Abstract

Inflammatory Bowel Disease (IBD) is a chronic gastrointestinal disorder driven by oxidative stress and immune dysregulation, often exacerbated by prolonged non-steroidal anti-inflammatory drug (NSAID) use. Conventional therapies provide symptomatic relief but are limited by severe adverse effects, necessitating safer alternatives. Channa striata (snakehead fish) is a rich source of albumin, essential amino acids, and bioactive compounds with potential immunomodulatory and anti-inflammatory effects. This study investigates the therapeutic efficacy of purified Channa striata albumin extract in an indomethacin-induced IBD rat model. Albumin was isolated via ammonium sulfate precipitation and characterized by SDS-PAGE, antioxidant activity (DPPH assay), and amino acid profiling. Rats were treated with Channa striata albumin (100-300 mg/kg BW) for 14 days post-indomethacin induction. Compared to controls and diclofenac-treated groups, the extract significantly reduced malondialdehyde (MDA) levels (up to 90.69%), improved jejunal histoarchitecture, and enhanced occludin expression. Immunohistochemistry showed a marked reduction in CD4+T cell infiltration, indicating immunomodulatory activity. These findings establish Channa striata albumin as a potent natural antioxidant and immunomodulator, offering a safer alternative to NSAIDs for IBD management.

Abstract

The development of intelligent packaging systems has become a promising approach to ensure food safety and quality by enabling real-time freshness monitoring. In this study, chitosan/polyvinyl alcohol (Cs/PVA)-based smart sensor films incorporated with roselle (Hibiscus sabdariffa L.) anthocyanins were fabricated and optimized for the visual detection of chicken and shrimp spoilage under variations storage. Anthocyanins were extracted from fresh roselle petals through different maceration periods (R1–R5) to investigate their influence on film properties. Physicochemical characterization revealed that extended maceration enhanced anthocyanin loading, leading to increased film thickness, higher color saturation, and improved optical responsiveness. FESEM micrographs demonstrated homogeneous polymer matrices at lower anthocyanin concentrations, while higher loadings induced micro-aggregates that enhanced volatile adsorption and sensing sensitivity. The fabricated films exhibited clear and progressive color transitions aligned with the spoilage process: red–purple at fresh conditions (pH 5–6), brown–green at intermediate spoilage (pH 7–9), and yellow–brown at advanced spoilage (pH ≥10), consistent with anthocyanin structural transformations. Storage trials with chicken and shrimp confirmed that the Cs/PVA–R5 film displayed the intense coloration and strong response to volatile amines such as ammonia, trimethylamine, and dimethylamine, enabling reliable freshness monitoring. Importantly, the films provided a visual indication when the pH exceeded the edibility threshold of 7.0–7.5, beyond which the samples were deemed unsuitable for consumption. Overall, this work demonstrates the potential of Cs/PVA–roselle anthocyanin films as eco-friendly, low-cost, and effective smart indicators for meat and seafood freshness, offering a practical platform for intelligent food packaging applications.
