OBJECTIVES To describe the clinical and neuroradiological features of basilar impression in patients with osteogenesis imperfecta type IV. METHODS Four patients with basilar impression were ascertained in a population study of osteogenesis imperfecta. All four had detailed clinical and neuroradiological examination with both CT and MRI of the craniocervical junction and posterior fossa struct...

Osteogenesis imperfecta is a rare connective tissue disorder characterized by bone fragility and low bone density. Most cases are caused by an autosomal dominant mutation in either COL1A1 or COL1A2 gene encoding type I collagen. However, autosomal recessive forms have been identified. We present a patient with severe respiratory distress due to osteogenesis imperfecta simulating type II, born t...

Objectives: Osteopenia is frequent in HIV-infected patients treated with antiretroviral therapy (ART) and has been linked to increased osteoclastogenesis. Little known about the effects of ART on osteogenesis. Design: We investigated effect human mesenchymal stem cells (hMSC) osteoblasts Darunavir Dolutegravir, most highly used as anchor drugs within a three-drug regimen, Atazanavir, which was ...

Activation of the canonical Wnt signaling pathway is an attractive anabolic therapeutic strategy for bone. Emerging data suggest that activation of the Wnt signaling pathway promotes bone mineral accrual in osteoporotic patients. The effect of Wnt stimulation in fracture healing is less clear as Wnt signaling has both stimulatory and inhibitory effects on osteogenesis. Here, we tested the hypot...

results treatments through mirnas can prove to be beneficial due to its small size, easy synthesis, targeted and quick delivery. conclusions further work is needed to be done to make mirna treatments available to large number of people suffering from various bone diseases. context mirnas can regulate the expression of genes by interfering in their mrnas, acting as key regulators of diverse cell...
