To overcome this problem, it is necessary to utilize waste to create economically viable products, such as Pangasius fish byproduct oil. This study aimed to evaluate the quality of crude Pangasius oil extracted from fillet processing byproducts (belly and trimming) using dry and wet rendering techniques and to assess its business potential with a value-added approach using the Hayami method. The oil extraction methods used include dry and wet rendering. The study examined two main treatment categories: extraction method (A), which included dry rendering (A1) and wet rendering (A2), and the types of Pangasius fillet industry byproducts (B), which comprised trimming (B1) and belly (B2). The best oil, extracted from the belly via dry rendering, showed favorable physicochemical properties: free fatty acids (0.88%), peroxide value (5.85 mEq/100 g), iodine value (65.55 g I₂/100 g), and saponification value (211.84 mg KOH/g). The oil was found to have considerable quantities of vitamins A (161.65 IU/g), D (192.40 IU/g), and K (3.20 IU/g), along with elevated levels of palmitic (40.70%), oleic (21.20%), and linoleic acid (10.60%). An economic assessment indicated that 1 kg of byproducts could produce 0.25 L of crude oil, which has a value-added of U.S.$ 1.62/L.

Trin. ex Steud and <i>Lemna minor</i> L. are non-native aquatic weeds. They disturb the habitat dynamics by competing with native flora for water and nutrition, deplete oxygen in water bodies, destroy water quality, and create habitat for mosquitoes and other parasites. Valorization of this huge biomass into biochar is a sustainable approach to address both environmental and agricultural challenges. It not only mitigates the climate issues by proper management but also sequesters carbon and improves soil quality. The current study manifests the utility of <i>Phragmites australis</i> and <i>Lemna minor</i> biomass as a feedstock for pyrolysis, at 400°C, 500°C, and 600°C, to design <i>Lemna minor</i> biochar (LMBC400, LMBC500, and LMBC600) and <i>Phragmites australis biochar</i> (PABC400, PABC500, and PABC600). These biochars were added as a soil conditioner to estimate the productivity of test crops. The results demonstrate that ash content, pH, electrical conductivity (ECe), and fixed carbon are directly proportional to pyrolysis temperature, whereas oxygen, hydrogen, nitrogen, volatile contents, and bulk density (BD) are inversely proportional to pyrolysis temperature. Scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy analyses proved that high pyrolysis temperature increases the porosity and phenolic compounds in biochar, which improves the surface quality. The percentage of nutrients such as Mg, Fe, N, Ca, N, P, K, and Zn increases by elevating pyrolysis temperature due to unlocking and release under the influence of heat. Soil quality parameters (viz. pH, BD, ECe, water holding capacity [WHC], total dissolved solids [TDS], and soil organic matter [SOC]) improved in favor of plant growth conditions, so the yield of test crops increased. So, LMBC600 and PABC600 had great potential to improve soil and productivity. It is a promising approach to manage this colossal volume of <i>P. australis</i> and <i>L. minor</i> through green technology by recycling this biowaste into a worthy product biochar, which is an alternative to chemical fertilizer in agronomical practices, which leave eco-toxic footprints and play havoc to the environment.</p>","PeriodicalId":21726,"journal":{"name":"Scientifica","volume":"2025 ","pages":"9303188"},"PeriodicalIF":2.3,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12490927/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145233564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we aimed to examine whether low-dose APAP could mitigate oxidative stress and neuroinflammation in a D-galactose (D-gal)-induced aging model. In our study, fifty adult male ICR mice were divided into five groups (<i>n</i> = 10). Except for the normal control group, all mice received D-gal subcutaneous injections (200 mg/kg) and were fed vehicle, 15 or 50 mg/kg APAP, or 100 mg/kg vitamin E daily for six weeks. After treatment, liver function was assessed by serum liver enzyme analysis. The liver and brain pathologies were examined using hematoxylin and eosin staining. Brain oxidative stress was evaluated through malondialdehyde (MDA) measurement. Additionally, immunohistochemistry was used to determine levels of inflammatory cytokines (TNF-α, IL-1β, TGF-β, and IL-10) and the oxidative stress marker, NADPH Oxidase 4 (NOX4). The study found no significant changes in serum liver enzymes or liver morphology among the experimental groups. However, the D-gal group exhibited increased neuronal cell loss, along with elevated levels of MDA and NOX4 in the frontal cortex and hippocampus. Moreover, D-gal mice showed elevated levels of TNF-α, IL-1β, and TGF-β, accompanied by decreased IL-10 levels. Notably, treatment with low-dose APAP and vitamin E mitigated neuronal cell loss, decreased MDA levels, and attenuated NOX4 expression induced by D-gal injection. Furthermore, low-dose APAP, particularly at 50 mg/kg, and vitamin E reversed the alterations in TNF-α, IL-1β, and IL-10 induced by D-gal, while TGF-β was unaffected.
