Efeito do pré-tratamento do treinamento de força e raloxifeno na periestropausa sobre a cicatrização óssea

Há evidências de que o treinamento de força (TF) e raloxifeno (Ral) durante a periestropausa promove melhor qualidade óssea. No entanto, nos perguntamos se os benefícios esqueléticos do TF ou Ral realizados durante a periestropausa persistiriam após a fratura. Portanto, o presente estudo teve como...

Melatonin suppression increases the incidence and progression of chemically induced oral cancer in rats

Estudos sugerem que a supressão de melatonina e disfunção circadiana em trabalhadores noturnos podem estar relacionadas ao desenvolvimento e à progressão do câncer. Pesquisas têm mostrado também que a incidência tumoral pode ser aumentada pela pinealectomia. Entretanto, nenhum estudo avaliou a i...

Efeitos do queijo probiótico com adição de Lactobacillus casei-01 na periodontite experimental em ratos

Objetivo: Este estudo avaliou os efeitos da ingestão de alimento funcional, queijo Prato contendo Lactobacillus casei-01, no desenvolvimento da periodontite experimental (PE) em ratos. Materiais e Métodos: 44 ratos machos Wistar foram divididos em 4 grupos (n = 11): C (controle) - animais sem indução...

Local treatment with ascorbic acid accelerates recovery of post-sutured Achilles tendon in male Wistar rats

Braz. j. med. biol. res; 52 (9), 2019
Tendon rupture is a very frequent accident involving average people and high-performance athletes. Clinical studies describe tendon recovery as a painful and slow process involving different biochemical and histological events. Ascorbic acid (AA) is a potent antioxidant as well as an important cofactor f...

Effect of stem cells combined with a polymer/ceramic membrane on osteoporotic bone repair

Abstract Cell therapy associated with guided bone regeneration (GBR) can be used to treat bone defects under challenging conditions such as osteoporosis. This study aimed to evaluate the effect of mesenchymal stem cells (MSCs) in combination with a poly(vinylidene-trifluoroethylene)/barium titanate (PVDF...

Methods: The groups consisted of Group 1: Ringer Lactate (RL) group, Group 2: HTK group, Group 3: UW group, Group 4: AF group. The livers of ra...

Difference of brain-derived neurotrophic factor expression and pyramid cell count during mastication of food with varying hardness

J. appl. oral sci; 27 (), 2019
Abstract Previous studies suggested that mastication activity can affect learning and memory function. However, most were focused on mastication impaired models by providing long-term soft diet. The effects of chewing food with various hardness, especially during the growth period, remain unknown. Objec...

Losartan improves alveolar bone dynamics in normotensive rats but not in hypertensive rats

J. appl. oral sci; 27 (), 2019
Abstract Hypertension is one of the main causes of premature death in the world; also, it is associated with several bone alterations. Preclinical studies have demonstrated delayed alveolar bone healing in hypertensive rats. However, losartan has been favorable for consolidation of bone grafts and reduct...

Natural history of experimental arthritis induced by Paracoccidioides brasiliensis in wistar rats

Abstract INTRODUCTION: Paracoccidioidomycosis (PCM) is the most prevalent systemic mycosis in Latin America. This study aimed to evaluate the natural history of Paracoccidioides brasiliensis-induced experimental arthritis of the knee joints in Wistar rats. METHODS: Rats were randomly allocated to eith...
