The pre-operative radiologic investigations (MRI and CT scans) revealed in the nine patients (60%) the extent of the compression to one vertebral body (C4 one case, C5 four cases, C6 four cases), while in the six cases (40%) the compression regarded two vertebral body (C3 and C4 one case, C4 and C5 two cases, C5 and C6 three cases). During surgery, when the decompression was judged completely, a CT scan was performed: in 11 cases (73.3%) the decompression was considered adequate, while in four cases (26.7%) it was deemed insufficient and the
surgical strategy was changed in order to optimize the bone removal. In these cases an additional scan was taken to prove the efficacy of DAPT ic50 decompression, achieved in all patients.
Intra-operative CT scan performed during cervical corpectomy is a really useful tool in helping to ensure complete selleck chemical bone removal and the adequacy of surgery. The O-arm((TM)) Image system grants optimal image quality, allowing correctly assessing the rate of decompression and, in any case of doubt, allows an intra-operative
evaluation of the final correct positioning of the graft.”
“The review generalizes and systemizes published data on the synthesis and chemical transformations of 4-(2-R-aryl)-1,2,3-thia- and -selenadiazoles. Powerful synthetic potential of 4-(2-R-aryl)-1,2,3-chalcogenadiazoles ensures their use in the synthesis of various heterocyclic compounds, such as 1-benzofurans, indoles, 1-benzothiophenes, 1-benzoselenophenes, and their more complex derivatives.”
“Dyes released by the textile industries pose a threat to the environmental safety. Recently. dye decolourization through
biological means has gained momentum as these are cheap and can be applied to wide range of dyes. This review paper focuses on the decolourization of dye wastewaters through fungi via two processes (biosorption and bioaccumulation) and discusses the effect of various process parameters like pH, temperature, dye concentration Adriamycin research buy etc. on the dye removing efficiency of different fungi. Various enzymes involved in the degradation of the dyes and the metabolites thus formed have been compiled. Genetic manipulations of microorganisms for production of more efficient biological agents, various bioreactor configurations and the application of purified enzymes for decolourization, which constitute some of the recent advances in this field, have also been reviewed. The studies discussed in this paper indicate fungal decolourization has a great potential to be developed further as a decentralized wastewater treatment technology for small textile or dyeing units. However, further research work is required to study the toxicity of the metabolites of dye degradation and the possible fate of the utilized biomass in order to ensure the development of an eco-friendly technology.
