Cell-in-cell phenomenon in urinary sediment: a case report

The internalization of apoptotic cells by non-phagocytic cells has been observed in different tissues and could be an important mechanism for the elimination of dying cells. Here, we describe a probable event of phagocytosis of apoptotic cells mediated by urothelial cells in urinary sediment. A 90-years-old male patient was admitted unconscious to the hospital, visible signs included: pale skin and dry mucous membranes, presumptively diagnosed as dehydration. Blood test revealed anaemia (haemoglobin 130 g/L) and hyperglycaemia (glucose 7.8 mmol/L), urinalysis showed a picture of urinary tract infection (leukocyturia and bacteriuria). The microscopic analysis of urinary sediment revealed the presence of urothelial cells and leukocytes internalized in urothelial cells. Anti-CD68 (membrane marker of macrophages) was tested by immunocytochemistry and a negative result was observed. Based on the findings phagocytosis of apoptotic cells mediated by urothelial cells was identified. This phenomenon can be observed in urinary sediment and should not be confused with a neoplastic process since it is a physiological event of cell elimination.     

Reading Comprehension and Predictability Effects on Sentence Processing: An Event‐Related Potential Study

Electrophysiology studies have identified two event‐related potentials that are modulated by predictive processes during language comprehension: the N400 and a frontal positivity. The N400 is smaller when words are presented within highly restrictive sentences, indicating reduced lexical retrieval costs. Violations of strong predictions generate larger frontal positivities, possibly reflecting inhibitory processes. More skilled comprehenders may exhibit enhanced predictive processing, but this possibility has seldom been investigated with event‐related potentials (ERPs). We analyzed the association between predictability ERP modulations and reading comprehension abilities. Twenty‐four undergraduate students were exposed to strongly and weakly constraining sentences, ending with an expected or unexpected final word. Their comprehension skills were assessed with a cloze task. Better comprehenders showed smaller N400s for expected words, and larger posterior positivities for unexpected endings, in strongly constraining contexts. These effects correlated with reading comprehension scores. The results suggest that better comprehenders take more advantage of predictions to reduce retrieval costs, and allocate more resources to postlexical integration processes.     

Legitimising inequality? The governance of ‘Others’ through participatory initiatives in schools

This article discusses how the call for families’ active participation in school can be understood as a form of regulatory act producing neoliberal subjectivities based on responsibility, entrepreneurship and rational calculation. The analysis draws on the results of two projects aiming to improve the relationship between families of Spanish Roma and immigrant background and the school. Results suggest that the idea of participation is presented as an element for the transformation of the schools. Nevertheless, the programmes are implemented without questioning the power structure present in school, and so put even more responsibility on the families, and make more visible their supposed deficits. Approaching participation as a key feature of neoliberal governmentality, our analysis highlights how these participatory initiatives foster a type of assimilationist diversity approach and legitimise the existing status quo in schools.     

我国国际职业足球运动员合同违约纠纷解决关涉的主要法律问题 ——以巴里奥斯案为例

近年来,国内频发的国际职业足球运动员合同违约纠纷已成为社会各界关注的热点问题。许多国内俱乐部在国际球员合同违约纠纷中败诉 或赔偿,巴里奥斯案是国内俱乐部第1次在国际球员合同违约纠纷中获胜并得到高额赔偿的案件。通过巴里奥斯案对国际球员合同违约纠纷所涉 及的争议管辖、法律适用、赔偿及裁决的执行等问题进行分析,国际足球职业球员合同违约纠纷受国际足联或国际体育仲裁院管辖;国际足联、国际 体育仲裁院的相关规则和判例都是处理此类纠纷的重要依据;国际足联、国际体育仲裁院对国际球员合同违约赔偿计算有明确的规定,也在判例中 形成了一定的计算原则,并阐述了赔偿金额计算的影响因素;职业足球已形成强大的行业体系,一般来说,国际足联、国际体育仲裁院决定都能得到 很好的执行。因此,国内的国际足球运动员合同违约纠纷一般向国际足联或国际体育仲裁院申诉,掌握和充分运用国际足联和国际体育仲裁院的 规则及判例是国内足球俱乐部解决国际球员合同违约纠纷的关键。赔偿的计算除了需要掌握相关规则及判例外,还要了解赔偿金额的影响因素, 对于国际足联、国际体育仲裁院的决定在国内的执行则无须疑虑。此外,遵守相关法律和规则,并及时有效地处理纠纷也是国内俱乐部在处理合同 违约争议中有效维护自身权益的重要方面。     

The internet as a celestial TiVo: What can we learn from cable television adoption?

It appears that the Internet is soon going to fulfill its potential to become a giant on-demand repository of television shows (and movies) available asynchronously, greatly increasing the variety of shows available at a moment in time. As companies such as Netflix and Hulu increase their activities in this sphere, there are many unanswered questions about the impacts of this transition. In this paper, we attempt to foretell the impact of Internet-induced increased variety on the amount of time individuals devote to viewing television. We use cable and satellite television’s impact on viewing as a proxy for the likely impact that future Internet transmission of programs will have. Using country-based panel data going back to the mid-1990s, we find that the increased variety brought about by cable and satellite has had virtually no impact on the amount of time devoted to television viewing. We discuss the import of this finding for Internet business models of television transmission.

Wisdom from Korean Reentry Counseling Professionals: A Phenomenological Study of the Reentry Process

The purpose of this phenomenological study was to explore the common experience of Korean counseling professionals who returned to South Korea after obtaining their doctoral degrees in the United States. Individual semi-structured interviews were conducted with ten Korean counseling professionals to understand their cross-cultural experience. The data were analyzed by phenomenological methods of inquiry. Seven themes emerged from the analyses: Reminiscence, Differences and Comparisons, Benefits, Challenges, Coping, Application and Modification, and Meaning. The findings suggested how the setting and context in which the reentry process occurred contributed to the participants’ experience as well as the essence of the reentry process. Implications of the results are discussed in the light of cross-cultural counseling and for future research and practice.
