Curcumin decreases astrocytic reaction after gliotoxic injury in the rat brainstem

Arq. neuropsiquiatr; 75 (8), 2017
ABSTRACT Recent studies have demonstrated that curcumin (Cur) has antioxidant, anti-inflammatory and anti-fibrotic effects. Ethidium bromide (EB) injections into the central nervous system (CNS) are known to induce local oligodendroglial and astrocytic loss, resulting in primary demyelination and neuroin...

Preliminary study on the biocompatibility and osteoconductive properties of a new bovine bone graft

Actual. osteol; 13 (2), 2017
To prevent post-extraction resorption and preserve the integrity of the alveolar ridges, the placement of bone grafts at the time of extraction is recommended. Bovine bone grafts are biocompatibile and osteoconductive, allowing new bone apposition by osteoprogenitor cells. Although there are trademarks r...
