Research ArticleOpen accessIn the abstractPurification, Structural Characterization and Anti-Aging and Stress Activities of Cordyceps Mycelium Polysaccharides from Paecilomyces HepialiXiaokang Hu, Huixiu Ma, Guicai Chen et al.This study identified and characterized the bioactive polysaccharide components from Cordyceps mycelium powder (CMP) derived from Paecilomyces hepiali, evaluating their anti-aging and stress-protective activities. Initial screening using Drosophila melanogaster revealed that crude Cordyceps polysaccharides (CCP) exhibited comparable effects to CMP and Cordyceps aqueous extracts (CAE) on natural lifespan and UV stress resistance, suggesting CCP as the primary bioactive component. CCP … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 16 Feb 2026 · 1,702 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Analysis of Wavelet, Curvelet, and Contourlet Transforms for Denoising Liver CT ImagesMajzoob Kamalaldin Omer AbdalrahmanLiver cancer is one of the leading causes of mortality worldwide, and early detection using CT imaging plays a critical role in patient survival. However, the quality of CT scans is often degraded by noise, particularly in low-dose imaging intended to minimize radiation exposure. This study presents a comprehensive comparison of three multiresolution transform techniques, namely the wavelet, curvelet, and … …Journal of Computer Science, Vol. 22, Issue 1 · 4 Feb 2026 · 2,124 accessesView PDFCite

Research ArticleOpen accessIn the abstractEffect of Processing Methods on Nutrient Composition of Black Soldier Fly Larvae Reared on Slaughterhouse Waste and Rice BranNurul Isnaini, Faizal AndriBlack Soldier Fly (BSF) larvae have emerged as a sustainable and nutrient-dense resource for livestock feed, primarily due to their high protein and lipid contents. However, the nutritional composition of BSF larvae is substantially influenced by the processing methods. This study aimed to evaluate the effect of five processing methods (room dried, sun dried, oven dried, microwave dried, and roasted) … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 3 · 4 Dec 2025 · 3,075 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdding Duckweed (Lemna minor) to Local Duck Diet: Determined Based on the Performance and Heavy MetalConcentration in their MeatSyamsuhaidi, Dwi Kusuma Purnamasari, Ryan Aryadin Putra, Uhud AbdullahAn experiment was conducted to determine whether addingduckweed fertilized with bioslurry to the diet corresponds to duckperformance and heavy metal concentration in their meat. The study wasdesigned using a completely randomized design. The treatments weredifferent levels of adding duckweed as a diet component, as follows: Basalfeed (control, no duckweed, TC), basal feed +2.5% duckweed (TL1), basalfeed +5% duckweed (TL2), basal … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 1 · 13 May 2025 · 5,847 accessesView PDFCite
