Emotion and the Advocacy Coalition Framework: An Affective Dynamics Perspective

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT Despite extensive evidence that emotion and cognition are deeply intertwined, the Advocacy Coalition Framework (ACF) lacks an analytically independent emotional mechanism in its causal architecture—an omission that may be particularly consequential in policy subsystems structured around morally charged, identity‐laden policy disputes.

烧伤创面内表皮生长因子、表皮生长因子受体、C-myc三种基因表达变化的临床观察

open access: yesZhongguo shiyan zhenduanxue, 2010
目的为探讨烧伤创面愈合机理,了解烧伤创面内表皮生长因子基因、表皮生长因子受体基因和C-myc基因的变化,为临床治疗提供依据。方法我们对25例病人烧伤创面的不同部位应用原位杂交方法,观察表皮生长因子基因、表皮生长因子受体基因和C-myc基因在烧伤创面肉芽中心部(肉芽中心部)、肉芽与愈合皮肤的交界部(创面交界部)、愈合皮肤部位(创面愈合部)和自身正常皮肤对照部位内表达强度和分布的特点。结果同一部位烧伤创面内,表皮生长因子基因和C-myc基因在交界部表达最强;烧伤创面中心部位表达次之,烧伤创面愈合部位表达较弱;

The Role of Messenger RNA Alternative Polyadenylation During Developmental Gene Expression Regulation and Adapdation of Rice [PDF]

open access: yes, 2016
水稻(Oryzasativa)不仅是世界上最重要的粮食作物之一,也是单子叶模式植物。水稻品种japonicaNipponbare和indica93-11为两个水稻亚种代表,广泛的种植于我国的南北区域,对环境与气候形成一定的适应性,在我国形成北粳南籼的生产格局。它们各自具有独自的生理特性和生长周期。转录组为特定生理条件下,细胞中全部转录产物的集合。通过对水稻发育过程转录组的研究,可以全面地了解基因表达调控在水稻发育过程中的调节作用以及对环境适应性。多聚腺苷化是基因在转录形成成熟的转录本之前的加工过程之一 ...

Partisanship, Deservingness, and the Attitudinal Policy Feedback Process for Social Policy

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT In an era of identity‐based partisan polarization, we examine whether social policies can still generate positive attitudinal feedback among beneficiaries. Drawing on nationally representative survey data, we demonstrate that partisanship conditions the policy feedback process through divergent perceptions of group deservingness.

Rfx2基因在小鼠睾丸中的表达研究

open access: yesZhongguo shiyan zhenduanxue, 2010
目的利用基因芯片筛选与精子发生相关的基因,并研究其表达特征。方法将4 d、9 d、18 d、35 d、54 d和6月龄小鼠睾丸组织cDNA与Affymetrix全基因组芯片进行杂交,筛选出差异表达的基因。通过RT-PCR分析差异表达基因在小鼠睾丸不同发育阶段中的表达。结果分析Affymetrix全基因组芯片杂交结果后,筛选得到1个差异表达杂交点,通过在NCBI网站与小鼠全基因组序列Blast分析可知该差异表达基因是Rfx2基因。该基因在4 d、9 d、18 d、35d、54 ...

Functional Study of Ecdysone Signaling Pathway Related Genes During Ovarian Maturation and Juvenile Development of The Mud Crab, Scylla paramamosain [PDF]

open access: yes, 2015
蜕皮激素在节肢动物蜕皮、附肢再生以及繁殖等生理过程起着重要作用。蜕皮激素受体(Ecdysonereceptor,EcR)在整个蜕皮激素信号通路中起重要作用。当蜕皮激素合成达到一定浓度以后,能够诱导EcR与维甲酸X受体(retinoidXreceptor,RXR)形成有功能的EcR/RXR异源二聚体,进而启动蜕皮激素信号通路产生级联反应,诱导E75、E74、BroadComplex(BR-C)等早期应答基因的转录。这些早期应答基因进一步调控下游一些蛋白酶和其它基因的陆续表达,产生次级应答 ...

Assessing D‐Squame as a Minimally Invasive Technique to Evaluate the Cutaneous Immune Response mRNA in a Dog Model of Canine Atopic Dermatitis

open access: yesVeterinary Dermatology, EarlyView.
ABSTRACT Background Canine atopic dermatitis (cAD) is a multifactorial, inherited skin disease, estimated to affect ≤ 15% of dogs. Studies of skin messenger mRNA in cAD currently use invasive methods, including blood sampling and biopsy collection, whilst advances in human atopic dermatitis study methodology have demonstrated reliable use of minimally ...

先天性脑积水小鼠大脑基因差异表达研究

open access: yesZhongguo shiyan zhenduanxue, 2008
目的系统探讨水通道AQP4敲除鼠先天性脑积水大脑基因表达差异。方法利用小鼠基因表达谱芯片对水通道AQP4敲除鼠先天性脑积水大脑基因表达水平进行检测分析。结果超过100个基因的表达水平发生显著改变,其中有超过63个基因表达明显上调,超过37个基因表达显著下降。结论这些基因表达水平的改变可能与先天性脑积水的形成密切相关,深入研究相关基因可能发现先天性脑积水形成的新机制。

Research of High-Dimensional Time-Varying Network Analysis Method [PDF]

open access: yes, 2016
网络分析尤其是相关网络分析方法一直以来应用于多领域的研究当中,在大数据浪潮不断革新数据分析方法的背景下,网络分析也面临着高维数据的处理问题。基于网络结构稀疏性的假定,许多相关研究提出关于高维网络数据的网络结构估计方法,这类方法主要对固定时期内的静态网络结构进行估计。然而,由于大量个体以及不确定影响因素的参与,网络个体间的关联结构也充斥着复杂性,结点间的关联结构也有可能随着时间的推移而发生动态的变化,仅凭借传统的静态网络分析并不能较好地刻画出网络结构的演化特征。 在本文的研究中,在详细论述相关网络理论 ...

h‐BN/HfO2 Interface‐Enabled Optoelectronic Doping for Low‐Voltage, Reconfigurable MoTe2 Nanoelectronics

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Engineering the semiconductor/dielectric interface is crucial for advancing two‐dimensional (2D) nanoelectronics, where device performance is predominantly governed by interfacial defects and dielectric coupling. Optoelectronic doping based on carrier trapping at the h‐BN/SiO2 interface has enabled non‐volatile and reversible carrier ...
