涉企职务犯罪刑事合规在改革实践中因公权力机关之间程序衔接不畅而收效甚微。其中,职务犯罪刑事合规的开展以监察机关在调查终结后将案件移送至检察机关为前提,有限的合规考察期、职务犯罪监察措施的出罪化运用等阻碍着检察机关后续开展刑事合规的职能发挥。立足于法律监督理论和组织责任中的法益可修复性,涉企职务犯罪刑事合规监检衔接具有相应的法理支撑。在《第三方意见》肯定监察机关具有对涉嫌行贿的企业适用第三方评估机制的建议权基础上,可进一步延伸监察机关参与职务犯罪刑事合规的职权,并对检察机关的介入程序予以明确,以促进涉案企业建立合规第三方评估机制,从而实现对职务犯罪的有效治理。

传染性法氏囊病(infectious bursal disease,IBD)是由传染性法氏囊病毒(Infectious bursal bursal virus,IBDV)引起的一种高度传染性疾病,以雏鸡法氏囊萎缩、腿肌出血等为特征性病变,给世界家禽产业造成重大经济损失。目前,由新型变异株引起的IBD在我国呈现流行趋势。为建立基于IBDV VP2蛋白的免疫学诊断技术,本研究以新型变异毒株IBDV-LY21/2为模板,扩增其VP2基因,随后构建重组原核表达质粒pCold-Ⅰ-IBDV-VP2并转化BL21(DE3)大肠杆菌进行诱导表达,通过考马斯亮蓝染色和Western blot检测重组蛋白His-VP2的表达情况,并对其进行纯化和浓度测定。将His-VP2免疫BALB/c小鼠后,采用iELISA检测血清抗体效价,最后制备单克隆抗体并对其鉴定。结果显示,获得的重组蛋白His-VP2分子量约为50 kDa,浓度为8 mg/mL;通过两次亚克隆获得3株杂交瘤细胞株1G10F12、3E3E9、4D12G12,且重链均为IgG1型,轻链均为κ型;其中1G10F12、3E3E9可与重组蛋白Myc-VP2产生Western blot和IFA反应,而4D12G12只能与其产生IFA反应。本研究为IBD诊断方法的建立奠定了基础,同时为深入研究VP2蛋白的功能提供生物学工具。

Thallium has been used geochemical exploration of gold deposits. However, as an indicator element in searching for hydrothermal the T1 minerals and mineralization are rare in nature. Lorandite T1AsS2, a relatively uncommon mineral, has been dominantly discovered in some Carlin gold deposits, and minor Sb- Hg, U and Pb-Zn-Ag deposits.

面对全球气候变化,亟需将“双碳”目标纳入国土空间规划实践。目前,以碳增汇为导向,针对中国西部地区、特别是西北干旱区县域的生态修复研究较少。本研究以中国新疆维吾尔自治区温宿县为例,从碳吸收能力与碳储量两方面综合评估温宿县碳汇现状,并以此为基础识别温宿县碳汇空间格局,探索以碳增汇为导向的县域国土空间生态修复规划的途径。现状评估结果表明,温宿县的碳汇重要性在不同地理区域呈现出较大差异。在研究区域内识别出一处碳汇腹地、两处碳汇重要区,以及总面积达2259.81km^(2)的碳汇潜力带,进而结合土地利用现状提炼出8种土地利用典型空间模型,并拟定了相应的生态修复策略。研究有助于促进“双碳”目标在国土空间规划中的落实,对中国西北干旱区域碳汇管理实践具有积极意义,并可为地理条件相似的地区提供固碳增汇的经验。
