myositis ossificans/hypoxia

Myositis ossificans developed in a 67-year-old man recovering from tetanus. This rare complication develops in the convalescent phase of tetanus through metaplastic changes in undifferentiated connective tissue cells in areas of myocellular injury. Anoxia, hematoma formation, and immobilization may

Segmental progeroid syndromes are commonly represented by genetic conditions which recapitulate aspects of physiological aging by similar, disparate, or unknown mechanisms. Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disease caused by mutations in the gene for ACVR1/ALK2 encoding

Heterotopic ossification (HO), the pathological extraskeletal formation of bone, can arise from blast injuries, severe burns, orthopedic procedures and gain-of-function mutations in a component of the bone morphogenetic protein (BMP) signaling pathway, the ACVR1/ALK2 receptor serine-threonine

Fibrodysplasia ossificans progressiva (FOP), is caused by mutations in the type I BMP receptor ACVR1 that lead to increased activation of the BMP-pSmad1/5/8 signaling pathway. Recent findings suggest that Activin A (Act A) promiscuously stimulates the bone morphogenetic protein (BMP) signaling

Hypoxia and inflammation are implicated in the episodic induction of heterotopic endochondral ossification (HEO); however, the molecular mechanisms are unknown. HIF-1α integrates the cellular response to both hypoxia and inflammation and is a prime candidate for regulating HEO. We investigated the

It was proven that compound C displays beneficial effects in models of inflammatory-induced anemia, ischemic stroke, and fibrodysplasia ossificans progressiva. Compound C influence on microglia, playing a major role in neuroinflammation, has not been evaluated yet. The aim of the present study was

Persistent vegetative state (PVS, apallic syndrome) has become a significant medical and social problem. The outcome of young people with PVS is a matter of great interest. Therefore, we analysed the outcome of 127 children and adolescents who were in PVS for at least 30 days following traumatic (n
