The ameliorative effect of selenium-loaded chitosan nanoparticles against silver nanoparticles-induced ovarian toxicity in female albino rats.
J Ovarian Res
January 2025
Department of Cytology and Histology, Faculty of Veterinary Medicine, Cairo University, Giza, Egypt.
Background: Recently, silver nanoparticles (Ag-NPs) were shown to provoke oxidative stress through the release of reactive oxygen species and consequently induce cell damage. Selenium-loaded chitosan nanoparticles (CS-SeNPs) have anti-inflammatory and antioxidant effects, indicating that they ameliorate Ag-NPs-induced ovarian toxicity.
Objective: This study aimed to assess how well CS-SeNPs counteract the damaging effects of Ag-NPs on the ovarian tissue of adult female albino rats.

The effect of chemically synthesized nanocomposites (NCs) of selenium (Se/AG NC), copper oxide (Cu/AG NC) and manganese hydroxide (Mn/AG NC), based on the natural polymer arabinogalactan (AG), on the processes of growth, development and colonization of potato plants in vitro was studied upon infection with the causative agent of potato blackleg-the Gram-negative bacterium -and the causative agent of ring rot-the Gram-positive bacterium (). It was shown that the infection of potatoes with reduced the root formation of plants and the concentration of pigments in leaf tissues. The treatment of plants with Cu/AG NC before infection with stimulated leaf formation and increased the concentration of pigments in them.

Universidad Autónoma de Nuevo León, Facultad de Salud Pública y Nutrición, Centro de Investigación en Nutrición y Salud Pública, Monterrey 64460, México.
Recent insights into the influence of nutrition on immune system components have driven the development of dietary strategies targeting the prevention and management of major metabolic-inflammatory diseases. This review summarizes the bidirectional relationship between nutrition and immunocompetence, beginning with an overview of immune system components and their functions. It examines the effects of nutritional status, dietary patterns, and food bioactives on systemic inflammation, immune cell populations, and lymphoid tissues, as well as their associations with infectious and chronic disease pathogenesis.

Pharmaceuticals (Basel)
November 2024
Department of Microbiology and Immunology, Faculty of Pharmacy, Tanta University, Tanta 31527, Egypt.
Background: The potent antioxidant lycopene has attracted a large amount of research attention given its potential health benefits. We aimed to assess the antimicrobial, anti-inflammatory, and antioxidant properties of lycopene (Lyc), selenium nanoparticles (Se-NPs), and lycopene selenium nanoparticles (Lyc-Se-NPs).
Methods: FTIR, polydispersity index, and zeta potential evaluations provided a complete characterization of the synthesized Lyc-Se-NPs.
Selenium Nanoparticles Suppressed Oxidative Stress and Promoted Tenocyte Marker Expression in Tendon-Derived Stem/Progenitor Cells.

Traumatic tendon injuries generate reactive oxygen species and inflammation, which may account for slow or poor healing outcomes. Selenium is an essential trace element presented in selenoproteins, many of which are strong antioxidant enzymes. Selenium nanoparticles (SeNPs) have been reported to promote tissue repair due to their anti-oxidative, anti-inflammatory, anti-apoptotic, and differentiation-modulating properties.
