电针激活Nrf2/HO-1通路抗帕金森病模型小鼠氧化应激的机制研究

目的 观察电针“风府”“太冲”“足三里”穴对帕金森病(Parkinson’s disease, PD)模型小鼠大脑纹状体中酪氨酸羟化酶(tyrosine hydroxylase, TH)、核因子E2相关因子2(nuclear factor-erythroid 2-related factor 2,Nrf2)、血红素加氧酶-1(heme oxygenase-1,HO-1)水平的影响,探讨电针治疗PD的可能机制。方法 将30只小鼠按随机数字表法分为对照组、模型组和电针组,每组10只。模型组、电针组小鼠按照30 mg/kg腹腔注射1-甲基-4-苯基-1,2,3,6-四氢吡啶(1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine, MPTP)制备PD小鼠模型。电针组小鼠给予“风府”“太冲”“足三里”穴电针干预,每日1次,每次30 min,连续干预12 d。其余两组小鼠不予任何干预。采用爬杆实验和悬挂实验观察3组小鼠行为学改变,旷场实验观察小鼠自主运动总路程,免疫组织化学法检测小鼠大脑纹状体中TH表达水平,实时荧光定量PCR法检测小鼠大脑纹状体中Nrf2、超氧...

The Green New Deal Must Preserve the Existing Nuclear Fleet

Abstract

As the largest source of carbon-free energy in the United States, nuclear energy must play a vital role in reducing emissions. This article suggests the Green New Deal, an ambitious federal proposal to address climate change, should aim to preserve the existing nuclear fleet by authorizing states to establish zero emission credit (“ZEC”) programs. The ZEC programs will provide credits, in the form of revenue, for the carbon-free attribute of nuclear energy. This article posits the ZEC programs should be based on a model ZEC program developed by the Federal Energy Regulatory Commission and explicitly authorized by amendment of the Federal Power Act to avoid issues of preemption.     

美朝核风波的实质与六方会谈的出路

美朝核风波再起的实质是美国霸权与朝鲜生存权的又一次政治博弈,美朝核风波的实质看成是生存权与霸权的政治博弈。进而为此展开的六方会谈框架又成为一组多方政治博弈平台。在美朝核风波愈演愈烈、几近战争临界值之际,中国从维护地区安全出发,积极出面斡旋,经三方会谈而达成了六方会谈框架。六方会谈的达成意义重大,舒解了“战争临界”;彰显了“中国作用”;取得了可视化成果。不应否认,六方会谈框架存在某种不足,却仍是解决朝核问题的最现实、最可行的方式。     

道路通行条件优化制度的建立

交通安全管理部门为履行好法律所规定的义务,必须将义务融会在道路通行条件安全隐患信息反馈、非交通性活动交通安全影响评价、道路交通安全管理设施优化、道路通行信息透明化四个制度之中,通过良好的运转机制,让履行义务成为一种日常的工作行为和规范化的工作过程,进而才能从优化道路通行条件这一层面提升道路交通安全管理的质量。     

司法鉴定在道路交通安全法实施中的运用

Coal and nuclear technologies: creating a false dichotomy for American energy policy

The American electric utility industry is entering a moment of transition. Once viewed as a stable and secure consortium of publicly regulated monopolies that produce and distribute electricity, the industry has weathered market restructuring only to face the ever-present risk of natural disasters, price fluctuations, terrorist attacks, and blackouts. This paper uses five criteria—technical feasibility, cost, negative externalities, reliability, and security—to evaluate the broad portfolio of energy technologies available to American electricity policymakers. Upon close inspection, energy efficiency practices, renewable energy systems, and small-scale distributed generation technologies appear to offer many advantages over large and centralized nuclear and fossil fueled generators. Contrary to the mimetic commentary produced by the media, these three approaches would present policymakers a superior alternative for curbing electricity demand, minimizing the risk of fuel interruptions and shortages, helping improve the fragile transmission network, and reducing environmental harm
