“Purpose Pseudomyogenic hemangioendothelioma is a soft tissue tumor found in young adults, predominantly males. The tumor has been reported in various locations in the body, including the head, neck, chest wall, abdominal wall, genital region, and extremities. Until now, there has been no indication of occurrence in the spine.
Methods A 25-year-old male Cilengitide purchase presented with spinal cord compression, due to an extradural tumor involving the third and fourth thoracic vertebrae with extension into the right pleural cavity.
Results
Histopathologic examination revealed a pseudomyogenic hemangioendothelioma, also described as epithelioid sarcoma-like hemangioendothelioma, orfibroma-like variant of epithelioid sarcoma.
Conclusion We describe the first occurrence of pseudomyogenic hemangioendothelioma in the thoracic spine. According to previous reports based on other locations, the tumor has an indolent buy Dibutyryl-cAMP clinical course with a small risk of metastasis, therefore complete macroscopic excision is the treatment of choice. Local recurrence may occur even with complete surgical resection, requiring close follow-up; adjuvant therapy is warranted.”
“Peculiarities of respiration of cells cultures producing biologically active compounds (isoprenoids and alkaloids) were
investigated in order to optimize productivity of culture growth and biosynthesis. It had been revealed that studied cells cultures of Dioscorea deltoidea Wall (producer of furistanol glycosides), Stephania glabra (Roxb.) Miers (producer of stepharin alkaloid) and Polyscias filicifolia Bailey (complex of biologically active agents) differ both in joint respiration activity and in ratio between cytochrome and cyanide-resistant respiration, while changes of rate of total oxygen consumption and activity of alternative oxidase during growth were found to be individual for every investigated
culture. Maximum rate of oxygen consumption for cells of D. deltoidea and S. glabra was marked in the period preceding active synthesis of secondary metabolites (lag phase for D. deltoidea and exponential phase for S. glabra). The revealed trends can be used for further monitoring and regulation Ruboxistaurin in vitro of growth and biosynthesis of secondary metabolites in producing cell cultures during deep cultivation.”
“Purpose In this article, we review the English literature of calcified pseudomeningoceles in the lumbar region.
Methods A systematic review using the Medline Database using the varied nomenclature for pseudomeningoceles, as well as reviewing the reference lists of relevant article found.
Results We discuss the different pathological theories on formation of a pseudomeningocele, the formation of a calcified wall and the optimal management for this entity. To date, 17 cases have been described, of which 13 are reviewed here. Calcification of pseudomeningocele is a rare entity and in the lumbar spine this occurs postsurgically.
