  Restoring masticatory functions,phonetics,deglutition and nasal regurgitation of oral intakes are challenging problems to overcome for hemimaxillectomy patients.A definitive solution for such surgery is the fabrication of prosthesis that improvises the impression procedures to accommodate the dimensional changes of the tissues and utilizes a two stage denture issuance technique.The 1st stage includes chair-side soft auto-polymerizing resin material over hollow bulb obturator denture issuance.Upon recall verifying the dimensional changes,2nd functional impression is recorded using the previously issued denture as a special tray.Permanent processed soft tissue conditioner is used as liner over the hollow-bulb obturator denture as final issued definitive and retentive prosthesis for 2nd stage denture issuance.Two stage denture issuance technique to fabricate a retentive,stable and functional prosthesis for hemimaxillectomy patients with soft tissue liner material minimize dimensional changes of the soft tissue.The defect sealing by the denture to the defect is improved and soft denture liner provides conditioning to the underlying tissues.

蛋白质的可逆磷酸化是生物信号级联传递的重要方式之一,是由蛋白激酶与蛋白磷酸酶共同参与完成的。蛋白质的磷酸化与去磷酸化反应对于信号的快速、精确传递起着无可替代的作用,是细胞内的重要调节机制,广泛参与植物的生长、发育、增殖、分化等生命活动。蛋白磷酸酶2C(PP2C)是一类丝氨酸/苏氨酸蛋白磷酸酶,植物PP2C广泛参与逆境信号传递过程,对环境胁迫如冷害、干旱、损伤等激活的信号通路发挥调节作用。本研究从小
