Antioxidant Fucoidans Obtained from Tropical Seaweed Protect Pre-Osteoblastic Cells from Hydrogen Peroxide-Induced Damage

Autor: Gabriel Pereira Fidelis, Cynthia Haynara Ferreira Silva, Leonardo Thiago Duarte Barreto Nobre, Valquíria Pereira Medeiros, Hugo Alexandre Oliveira Rocha, Leandro Silva Costa

Publikováno v: Marine Drugs, Vol 17, Iss 9, p 506 (2019)

Some antioxidant compounds decrease the amount of intracellular reactive oxygen species (ROS) and consequently reduce the deleterious effects of ROS in osteoblasts. Thus, these compounds fight against osteoporosis. Brown seaweeds are a rich source of

Publikováno v: International Journal of Surgery. 24:120-123

Background Several cases of delayed bone consolidation have been treated with extracorporeal shock wave therapy (ESWT) to improve bone healing and a key role of the extracellular matrix glycosaminoglycans in osteogenesis has been suggested. Objective
