Prevention of neurotoxicity and cognitive impairment induced by zinc nanoparticles by oral administration of saffron extract
AbstractThe accumulation of relatively higher dose of zinc oxide nanoparticles in brain was reported to produce neurotoxicity. Indeed, nanoparticles have a high ability to penetrate biological membranes and be uptaken by cells, which may cause cell disorders and physiological dysfunctions. The aim of the current study was to evaluate, whether oral administration of saffron extract, in rats, can protect from neurotoxicity and behavioural disturbances induced by chronic administration of ZnO-NPs. Daily oral administration of ZnO-NPs was performed for 21 consecutive days to induce oxidative stress-like situation. Then after t...

Isospora bertoi n. sp. of the saffron finch, Sicalis flaveola (Aves: Passeriformes) from Brazil1
Braz J Biol. 2023 May 22;83:e270649. doi: 10.1590/1519-6984.270649. eCollection 2023.ABSTRACTA new species of coccidia (Protozoa: Apicomplexa: Eimeriidae) is described from the saffron finch, Sicalis flaveola, is reported from Brazil. Sporulated oocysts of Isospora bertoi n. sp. are spherical to subspherical; 23.6 (21.1-26.5) x 22.0 (19.4-24.6) µm; shape Index (L/W ratio) 1.1 (1.0-1.2) µm; with bilayer smooth walls, ~1.1 μm. Micropyle and oocyst residuum are absent, but polar granules are present. Sporocysts are elongated ellipsoidal, 16.2 (13.6-17.9) x 10.1 (8.9-12.4) µm. Stieda body is button-shaped and Sub-Stieda an...
