高压氧对小鼠学习记忆及脑细胞形态结构的影响 总被引:2,自引:0,他引:2
实验用两种行为模型(旷场行为模型和Y-迷宫分辨学习模型)观察了幼龄小鼠在不同压力的高压氧处理后,对新异环境的探究行为和自发活动情况,以及学习记忆能力的变化;并用XY-生物医学电脑图像分析仪分析了与学习记忆相关的脑区(大脑皮层、海马)神经元密度,细胞核面积,胞核/胞浆比值的变化。结果表明:(1)与对照组相比,吸0.1MPa高压氧的幼鼠学习记忆能力明显提高,相关脑区的神经元密度、细胞核面积、胞核/浆比均显著增加。(2)吸0.25MPa高压氧的幼鼠学习记忆能力与对照组相比无明显变化,但其在新异环境中的自发行为明显减少。提示:慢性吸入0.1MPa高压氧有利于促进幼鼠脑的生长发育,增强脑功能活动。 相似文献

Due to the limited research demonstrating socially valid outcomes of function‐based treatments in ecologically relevant environments (Santiago, Hanley, Moore, & Jin, 2016), we replicated and extended the effects of the interview‐informed functional analysis and skill‐based treatment procedure described by Hanley, Jin, Vanselow, and Hanratty (2014) with two children diagnosed with autism in a home setting. The assessment and treatment was implemented by a home‐based service provider and treatment was extended to the participants’ parents. Following the interview‐informed functional analyses, we taught the participants functional communication responses and to engage in less‐preferred activities when functional communication outcomes were delayed. We observed large reductions in problem behavior following the introduction of the function‐based treatment. The effects extended to novel settings, stimuli, and caregivers and the results maintained at 6‐week follow‐ups. 相似文献

The bundling literature largely holds that a person's reaction to a given product bundle depends only on the characteristics of the products contained in the bundle. This paper, instead, proposes that people evaluate bundles in reference to other bundles that they have seen. Prior research indicates that people are sensitive to a bundle's “attribute inventory” or the aggregate level of comparable attributes possessed by its constituent products. We show that when people evaluate a bundle, they compare the attribute inventories that it offers to those offered by other bundles that they have seen. The resulting compositional comparisons can occur without changes to the products that comprise the target and contextual bundles, vary by attribute comparability and attentional focus, and coexist with (and at times reverse the effects of) well‐established product‐specific context effects, which are determined solely by the products and their attributes. 相似文献

This study tested the Selection Procedural Justice Scale (SPJS) in an educational setting. The sample consisted of 617 students. Four different confirmatory models were tested, followed by an IRT analysis to test the scale structure at the item level in the two different contexts (selection vs. academic exams). Results indicated that the 11‐factor structure is the best factorial solution, and SPJS items were found to be free of DIF. 相似文献

Elizabeth Grosz's interpretation of Darwinian evolutionary theory to ground a feminist ontology of biology has been particularly controversial. Most critics have understood Grosz as supporting her theory with empirical evidence, and they criticize her for being either inaccurate or uncritical of and overly dependent on science. I argue that Grosz reads Darwin as a philosopher in a Deleuzian and Irigarayan sense, and that Grosz's project is therefore better understood in terms of its ethical and political goals rather than in terms of empirical adequacy. Employing this evaluative framework leads to a novel route for critique of Grosz's ontology in terms of its reliance on the Darwinian distinction between organism and environment. I conclude that Grosz's work is valuable for the way it maintains ethical and political considerations in feminist ontological debates, and that introducing a more sensitive understanding of the organism–environment relation will lead us closer to a truly feminist ontology of biology. 相似文献

To differentiate romantic disillusionment from similar constructs of dissatisfaction and regret, functional Magnetic Resonance Imaging (fMRI) data obtained when romantically involved individuals (N = 39) were reminded of relationship events representing these emotions were analyzed. Whole‐brain activations suggested disillusionment‐linked processes not observed for dissatisfaction or regret. Compared to dissatisfying events, disillusioning ones showed greater activity in regions pertaining to evaluation, reflection, and reconciling conflicting information (e.g., anterior cingulate cortex). No regions showed significantly more activation for dissatisfying than disillusioning events. Compared to regret‐inducing events, disillusioning events showed greater activation in areas thought pertinent to detail processing and decision making (occipital fusiform and lingual gyrus). Regret‐inducing events activated regions suggesting the planning and thoughts of how one could have acted differently (e.g., prefrontal cortex). 相似文献

The coming together of parenting and routine posting on social networking sites has become a visible and recognisable theme, and the term “sharenting” has found a place in everyday talk to describe some forms of parental digital sharing practices. However, while social media has undoubtedly provided a space for parents to share experiences and receive support around parenting, sharenting remains a contestable issue. Thus, one reading of sharenting would be as a display of good parenting as mothers “show off” their children as a marker of success. However, the term also can be used pejoratively to describe parental oversharing of child‐focused images and content. In this paper, we explore the practice of sharenting in terms of pride, affect and the politics of digital mothering in a neoliberal context to conclude that sharenting can be best understood as a complex affective and intersectional accomplishment that produces motherhood and family as communicative activities within digital social practices. 相似文献

Women are an important part of the medical workforce, yet little is known about gender differences in psychological morbidity, burnout, job stress and job satisfaction among neurologists. This study assessed gender differences in a large national sample of Chinese neurologists. Multivariate analyses were performed to examine associations. A total of 5558 neurologists were included in the analysis. Compared with their male counterparts, female neurologists were generally younger; were less likely to be married or to have children; had higher levels of education; were in practice for a shorter period of time; were less likely to hold senior roles; and had lower incomes. Male and female neurologists worked similar hours and spent a similar number of nights on call. No gender differences were found in psychological morbidity, burnout, and high levels of job stress for female and male, respectively. Women had higher emotional exhaustion scores, while men were more likely to have low levels of job satisfaction. The multivariate analysis showed that factors independently associated with psychological morbidity, burnout, high levels of job stress and low levels of job satisfaction were generally similar for women and men. These findings increase our understanding of gender differences in psychological morbidity, burnout, job stress, and job satisfaction among neurologists. As more women join the medical profession, these differences may be useful in designing medical training and practice. 相似文献
