A análise por imagem das condições morfológicas do osso alveolar é essencial para o planejamento de tratamentos de diversas especialidades na odontologia. Porém, a maioria dos métodos de imagem utilizam radiação ionizante. Assim, a ressonância magnética (RM) ganha grande importância na pesqui...
OBJECTIVE: Hematopoietic stem-cell transplantation (HSCT) childhood survivors of hematologic malignancies are prone to develop late osteopenia and osteoporosis. The purpose of this retrospective study was to quantitatively and qualitatively assess bone mineral density (BMD) in HSCT childhood survivors an...
Cuscuta chinensis Lam. (Convolvulaceae) is an important herbal medicine widely used to improve sexual function, treat osteoporosis, and prevent aging, and has been reported to exhibit anti-osteoporotic effects in vitro. However, the activity of Cuscuta chinensis Lam. on glucocorticoid-induced osteoporosi...
