Acalculia in aphasic patients should be better investigated in order to understand if it is a simple comorbid or if it is influenced by language disorders. This study aimed to compare the performance on EC301 battery calculation tasks between aphasic and normal subjects and sought to verify a possible association between number processing and calculation skills and linguistic changes in aphasic patients, in order to investigate if language disorders interfere with number processing and calculation. Analytical cross-sectional study with a control group, performed of the Department of Speech and Hearing Disorders of a public university, conducted in the city of São Paulo, Brazil. First, to analyze the specific difficulties encountered in numerical processing and calculation tasks among the aphasic group, aphasic and healthy adult’s performance in specific calculation tasks were compared. The calculation tasks, which had been badly performed by aphasic patients, were selected. Aphasic patients were also submitted to the language tasks from Montreal-Toulouse Protocol: oral and written comprehension, repetition, reading aloud, naming and dictation. We observed that aphasic individuals showed changes in numerical processing and calculation tasks that were not observed in the healthy population. The most important finding of this study was that aphasic individuals showed changes in numerical processing and calculation that were positively associated to their linguistic performance. The strong associations between battery EC301 and linguistic tasks suggest that language disorders interfere with number processing and calculation.

This study aims to fertilize research on parental mediation with the importance of parents＇ media attitudes in terms of parental third-person effects and its varieties. The explanatory power of these perceptions on behavioral consequences as types of parental mediation is analyzed with control for previously known factors. Data from a cross-sectional population survey in Sweden 2011 covered a representative sample of children, aged 2-17 years in total 1461. The results show that the parental second-person perceptions explain （i.e., general belief in media effects） more than parental third-person perceptions. Parental second-person perceptions together with the age of the child explain most of the restrictive mediation and the effects of parental second-person perceptions on restrictive mediation increase with the parents lesser control of the media type.

The authors describe the clinical presentation of a 59-year old woman in the emergency room, with agitation, confusion and hypothermia. She was previously diagnosed with hypothalamic-pituitary insufficiency with complete dysfunction of the pituitary gland, poikilothermia and central diabetes insipidus, treated with hormone supplements. In the emergency room, she showed a dysregulation in temperature, altered mental status and hyponatremia. The differential diagnosis was hypothermia based on infection with the history of poikilothermia, with dysregulation of her diabetes insipidus. Poikilothermia is an extremely rare condition in humans in which the body temperature variates with the surrounding temperature. Dysregulation may develop due to different causes.

频繁的海上溢油事故和工业含油污水的肆意排放严重破坏海洋生态平衡。因此,开发先进的除油材料迫在眉睫。石墨烯(G)及其衍生物氧化石墨烯(GO)因其具有高比表面积、低密度、高孔隙率、表面功能可调等优异的理化性质,在油水分离领域成为研究热点。为充分发挥其优势,近年来,将G或GO与聚合物复合制备成功能化G/聚合物或GO/聚合物纳米复合材料,因其具有良好的除油能力、优异的机械性能、价格低廉、形貌及表面化学组分可调等优势而越来越受到人们的青睐。目前已开发出气凝胶、泡沫、海绵、膜等具有三维结构的G/聚合物或GO/聚合物复合吸油剂和过滤膜。本文系统性地总结了从表面润湿理论到G/聚合物或GO/聚合物复合吸油材料和滤膜材料的最新研究进展。此外,重点归纳了近年来有关油品回收及吸油材料再生的方法策略。最后,提出该研究领域目前面临的挑战和未来研究方向,旨在为该领域的深入探索开辟新的视角。

Cervical cancer is the second most common type of cancer among women worldwide. In Sweden cervical cancer is the fifteenth most common cancer among women and accounts for 1.9 percent of all female cancers. The Swedish Pap smear screening program is enabling early detection of cell changes in order that treatment may be administered to prevent the development of cancerous cells. There are approximately four hundred and fifty cases of cervical cancer detected each year in Sweden and of these cases, approximately seventy five percent occur in women who do not participate in the screening and testing program. The purpose of this study was to illustrate and examine the reasons why women did not participate in the program even though they had received a notice that they had an appointment for a Pap smear test. In the study fourteen women from a district in the west of Sweden were interviewed. In order to analyse the interviews a qualitative content analysis according to Lundman and Graneheim was used. The analysis resulted in the development of three categories which were identified as communication, treatment and subterfuge (reasons or excuses for not participating). The theme of the study was the professional treatment of the women’s conditions. In the interviews the women emphasize the importance of professional treatment that is administered with respectful and sympathetic care throughout the whole healthcare system regardless of where and when the visit was conducted. Efficient organization and clear communication would minimize the inconvenience for the women during their visit.

We review the progress and future possibilities in the emerging area of molecular spintronics. We first provide an overview of the different transport regimes in which electronic nanodevices can operate, then briefly overview the important characteristics of molecular magnetic materials that can be useful for application in spintronics and we eventually present several schemes to include such systems into spintronic nanodevices. We hightlight the importance of a chemical approach to the area, and in the last section we showcase some approaches to the creation of hybrids made of carbon nanostructures and molecular magnets, which are gaining increasing attention.
