Autor: Mohamed Hamed, Alaa G. M. Osman, Ahmed E. A. Badrey, Hamdy A. M. Soliman, Alaa El-Din H. Sayed
Publikováno v: Frontiers in Physiology, Vol 12 (2021)
This study aims to assess the impact of microplastics (MPs) on erythrocytes using eryptosis (apoptosis) and an erythron profile (poikilocytosis and nuclear abnormalities), considered to be novel biomarkers in Nile tilapia (Oreochromis niloticus). In

Ultrastructural studies of the morphological variations of the egg surface and envelopes of the African catfish Clarias gariepinus (Burchell, 1822) before and after fertilisation with a discussion of fertilisation mechanism
Autor: Imam A. A. Mekkawy, Alaa G. M. Osman
Publikováno v: Scientia Marina, Vol 70, Iss S2, Pp 23-40 (2006)
Much of the existing knowledge of the mechanisms involved in teleost fertilisation is based on a few small model species that have no commercial value. Research is therefore urgently required to address mechanisms involved in fertilisation in species

Antioxidants and molecular damage in Nile Tilapia (Oreochromis niloticus) after exposure to microplastics
Autor: Alaa El-Din H. Sayed, Mohamed Hamed, Alaa G. M. Osman, Hamdy A.M. Soliman
Publikováno v: Environmental Science and Pollution Research International
Recently, research on the biological effects of microplastics (MPs) has grown exponentially. However, effects of MPs on freshwater fishes and the mechanisms of the biological effects of MPs were limited. So, the purpose of the current study was to cl
