1Long-term survival of a patient after resection of a gastrointestinal stromal tumor arising from the pancreas显示文摘BACKGROUND:Gastrointestinal stromal tumors (GISTs) may arise in any part of the gastrointestinal tract;extragastrointestinal locations are extremely rare.Only a few cases of extragastrointestinal stromal tumor arising from the pancreas were reported.None of the reports described a long-term follow-up of the patients.METHOD:This report describes an interesting and unusual case of GIST arising from the pancreas.RESULTS:A 74-year-old female presented with a palpable abdominal mass.CT scan showed a large mass 11×8×4 cm originating from the tail of the pancreas.Percutaneous biopsy revealed a GIST predominantly with spindle cells,but some parts also contained epitheloid cells.The patient was treated by distal pancreatic resection with splenectomy.Immunohistochemistry of the tumor showed a staining pattern characteristic of GIST.The patient has achieved a long-term survival of five years and six months without any sign of recurrence of the disease.CONCLUSION:This is the first reported case of an extragastrointestinal stromal tumor arising from the pancreas treated surgically,with a long-term survival.Filip eka Bohumil Jon Alexander Ferko Zdeněk ubrt Dimitar H Nikolov Věra Tyová 2011Hepatobiliary & Pancreatic Diseases International2011,10,3:3
2MgO-based adsorbents for CO2 adsorption:Influence of structural and textural properties on the CO_2 adsorption performance显示文摘A series of MgO-based adsorbents were prepared through solution–combustion synthesis and ball-milling process.The prepared MgO-based powders were characterized using X-ray diffraction,scanning electron microscopy,N_2 physisorption measurements,and employed as potential adsorbents for CO_2 adsorption.The influence of structural and textural properties of these adsorbents over the CO_2 adsorption behaviour was also investigated.The results showed that MgO-based products prepared by solution–combustion and ball-milling processes,were highly porous,fluffy,nanocrystalline structures in nature,which are unique physico-chemical properties that significantly contribute to enhance their CO_2 adsorption.It was found that the MgO synthesized by solution combustion process,using a molar ratio of urea to magnesium nitrate(2:1),and treated by ball-milling during 2.5 hr(MgO-BM2.5h),exhibited the maximum CO_2 adsorption capacity of 1.611 mmol/g at 25℃ and 1 atm,mainly via chemisorption.The CO_2 adsorption behaviour on the MgO-based adsorbents was correlated to their improved specific surface area,total pore volume,pore size distribution and crystallinity.The reusability of synthesized MgO-BM2.5h was confirmed by five consecutive CO_2adsorption–desorption times,without any significant loss of performance,that supports the potential of MgO-based adsorbent.The results confirmed that the special features of MgO prepared by solution–combustion and treated by ball-milling during 2.5 hr are favorable to be used as effective MgO-based adsorbent in post-combustion CO_2 capture technologies.Gutiérrez-Bonilla Elvira Granados-Correa Francisco Sánchez-Mendieta Víctor Morales-Luckie Raúl Alberto 2017Journal of Environmental Sciences2017,29,7:3
