Management of low-grade gliomas (LGG) is based on clinical and radiologic features, including the Pignatti prognostic scoring system, which classifies patients as low- or high-risk. To determine whether molecular data can offer advantages over these features, we have examined the prognostic impact of several molecular alterations in LGG. In a cohort of 58 patients with LGG, we have retrospectively...
Abstract We present a case of congenital epulis, diagnosed prenatally with US. Congenital epulis is a benign gingival tumour whose differential diagnosis includes other oral-facial masses such as haemangioma, granular cell myoblastoma and cystic hygroma. This tumour can cause obstruction of the airway or feeding problems in the newborn child. Surgical excision is the treatment of choice.
From experimental results obtained in a wide range of operating conditions (temperature and contact time) in an isothermal fixed bed integral reactor, the validity both of the kinetic models proposed in the literature as well as their modifications, for the methanol-to-gasoline (MTG) process at zero time on-stream, has been studied. The kinetic parameters for the various models have been calculated...
