A few signaling pathways are driving the growth of hepatocellular carcinoma. Each of these pathways possesses negative regulators. These enzymes, which normally
Background Among the deaths due to trauma,about one half of the patients suffer from road traffic injury(RTI).Most of RTI patients complicate acute respiratory
The limited efficacy of cytotoxic therapy for advanced biliary tract and gallbladder cancers emphasizes the need for novel and more effective medical treatment
AIM:To study halothane hepatitis (HH) in Iran and its associated risk factors. METHODS: We retrospectively studied files of all cases diagnosed with HH referred
采用模拟废水研究了总氮负荷为9.33 kgTN/(m3.d)的条件下,改变进水pH值对厌氧氨氧化UASB反应器运行性能的影响。结果表明,进水pH值为7.00～7.20时处理效果最佳,对氨氮和亚硝态氮的平均去除率分别为97.4%、97.7%。进水pH值低于6.00或高于9.00时厌氧氨氧化反应完全停止,低pH值冲击可通过延长HRT的手段使反应器在20 d内恢复正常;高pH值冲击会对反应器造成不可逆抑
AIM:To assess whether in ulcerative colitis (UC) patients with ileo-rectal anastomosis (IRA),ileal lesions may develop in the neo-terminal-ileum and their possi
Background Human metapneumovirus (hMPV) has recently been recognized as a notable respiratory pathogen in children.However,no isolation processes and only a lim
利用不同廉价离子交换膜作为填料型微生物燃料电池(MFC)的分隔材料,考察其运行情况,表征其内阻、极化曲线、功率密度、膜面电阻以及对有机物和氧气的扩散系数。结果表明:相比以阳离子交换膜作为分隔材料的MFC(CMFC),以阴离子交换膜作为分隔材料的MFC(AMFC)内阻更低,功率密度更高,最大功率密度可达2.4 W/m2。在长期运行过程中AMFC的内阻及膜面电阻变化均较小。长期运行后,阳离子交换膜靠着
采用生物滤池处理高铁、高锰、高氨氮地下水时,存在启动时间长的问题,鉴于此,采用双层滤料、单层滤料回流、单层滤料不回流三种启动方式同时启动三根滤柱,考察双层滤料和回流对启动时间的影响。结果表明,采用双层滤料或回流均能有效缩短启动时间,三根滤柱出水中的总铁、锰、氨氮分别在第82、81、103天降到了0.3、0.05、0.2 mg/L以下。进一步的分析发现,铁主要在0～0.4 m滤层被去除,锰的去除最初
