“…The histological changes in the cardiac tissues of the ASP-treated rats indicated myocardial injury, as demonstrated by the deformation of the nuclei of the cardiomyocytes and the disarray or disorder of the cardiac myofibrils. These alternations are consistent with previous studies [ 46 ; 13 ].…”

Aspartame (ASP) has been used as an alternative to sucrose for diabetics and obese people worldwide. Co-administration of L-carnitine (LC) with ASP has a protective effect against the liver and kidney toxicity induced of ASP. The goal of the investigation was to assess the enhancement of LC effect on the cardiac toxicity caused of ASP. The rats were divided into 6 groups: control with saline, LC (10 mg/kg), ASP (75 mg/kg), ASP (150 mg/kg), LC with 75 mg/kg of ASP, and LC with 150 mg/kg ASP. The antioxidants were determined by measuring the activities of myeloperoxidase, xanthine oxidase, superoxide dismutase, catalase, and glutathione peroxidase, and by assessing the levels of lipid peroxidation, total thiols, and glutathione. There was a significant elevation in LPO, in conjunction with a significant decline in the enzymatic antioxidants superoxide dismutase, catalase, and glutathione peroxidase and the non-enzymatic antioxidants glutathione and thiols. The cardiac myofibrils were found in a disarrayed pattern in ASP treated-animals as compared to the control rats. The animals treated with ASP-HD showed more than one apoptotic cell with a large tail and a small head, and the relaxed loops of the damaged DNA were extended to form a comet-shaped structure. These effects may be due to the excessive generation of reactive oxygen species by ASP, which reduces cardiac function. Co-administration of LC with ASP improved all of the above-mentioned parameters that were disrupted of ASP alone. This study evidences a sufficient originality in showing how LC plays a positive role against cardiac toxicity of ASP.

“…The cassava peel mediated synthesized AgNPs showed an absorption peak at 434.4 nm in the UV–Vis spectra (Figure 1), which is characteristic for AgNPs. The findings obtained agree with the previous studies published (Balashanmugam, & Kalaichelvan, 2015; Gudadhe et al, 2014; Kowsalya et al, 2019; Ramachandraiah et al, 2017).…”

Biodegradable nanocomposite films have been developed by incorporating silver nanoparticles (AgNPs) into the gelatin biopolymer matrix for food packaging applications. AgNPs were biologically synthesized using industrial food waste, namely, cassava tuber peels. The cassava peels mediated synthesized AgNPs exhibited a maximum absorbance peak at 434.4 nm in the UV–Vis spectrum. High‐resolution transmission electron microscopy results revealed spherical shaped particles with a size range of 10–45 nm. The presence of elemental silver and crystalline nature of AgNPs was confirmed by Energy‐dispersive X‐ray spectroscopy and X‐ray diffraction analyzes. AgNPs showed significant antimicrobial activity against foodborne pathogens. Field emission scanning electron microscopy images of the films showed the successful incorporation of AgNPs into the gelatin matrix. AgNPs integration has demonstrated improvement in the mechanical and barrier properties of nanocomposite films. The gelatin–AgNPs nanocomposite films have resulted in an excellent notable increase in the shelf life of sapodilla fruits. This confirms that the gelatin–AgNPs nanocomposite films are ideal for the food packaging industry to extend the shelf life of packaged food. Practical applications The use of silver nanoparticles as an antimicrobial in the field of food technology has been of great interest in recent years. The present study highlights the importance of the use of industrial food waste for the synthesis of silver nanoparticles and its incorporation into the gelatin matrix for the preparation of thin nanocomposite film. Gelatin–AgNPs nanocomposite film showed enhanced UV‐shielding and antimicrobial properties, which increased the shelf life of sapodilla fruits. AgNPs incorporated gelatin nanocomposite film could prove to be an effective antimicrobial food packaging material and an efficient way to extend the post‐harvest life of food.

Recycling wastes and providing their use in useful fields attract attention every day. In our study, with the extract prepared from the parts of the Cynara scolymus L. (artichoke) plant that is not suitable for human consumption, silver nanoparticles were easily synthesized in an ec-friendly, energy-free way. Characterization of the obtained nanoparticles was done with a UV-visible spectrophotometer (UV-Vis.), fourier transform infrared spectroscopy (FTIR), X-ray diffraction diffractometer (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), and zeta potential analysis data. In these data, it was determined that AgNPs have a maximum absorbance at 458.8 nm wavelength, a crystal nanosize of 28.78 nm, and a spherical appearance. The zeta potential of (-) 16.9 mV indicates that silver nanoparticles exhibit a stable structure. Particles show antimicrobial effects on pathogenic species at concentrations of 0.03-0.25 μg/ml, and it was determined by using the minimum inhibition concentration (MIC) microdilution method. By examining their cytotoxic effects on U118, CaCo-2, and Skov-3 cancer cell lines and healthy HDF cell lines by the MTT method, concentrations of inhibitive effects on survival were determined.
