The use of osteosynthesis materials in orthopedics is fundamental in the surgical management of patients presenting with various pathologies of the locomotor system, in most cases trauma, but also malign and benign tumors. The risk that these materials could have in inducing malignant transformation of benign tumors or in the onset of primary malignant tumors, was rarely studied. On the one hand, primary malignant tumors of the locomotor system are much less frequent than other kind of neoplasms (for example Ewing sarcoma has an incidence of 1-3 cases / 1.000.000 people / year, ostosarcoma has an incidence of 2 cases / 1.000.000 people / year). On the other hand, usually there is a time window of several years, different from one case to another, from the moment of action of the etiopathogenic factor to the moment of revealing the presence of a neoplastic disease. Based on our clinical practice on a few clinical cases, we intend to study more thoroughly the etiology of primary bone malignant tumors in general and the role of the osteosynthesys materials in this matter especially.

The immunohistochemical expression of p63, ΔNp63, and p53 was studied in mixed tumors of canine mammary glands (13 benign mixed tumors and 19 carcinomas arising from benign mixed tumors) to determine the role of p63 and its isoform ΔNp63 in the development of mixed tumors, as well as to assess its relation with p53. P63 was expressed in myoepithelial cells of all benign mixed tumors and in 18 of 19 carcinomas in mixed tumors. The p63-negative carcinoma in mixed tumors was invasive, and a loss of p63 was detected in the other malignant tumors showing a discontinuous p63-stained myoepithelial layer. ΔNp63 was expressed in all benign mixed tumors but only in p63-positive carcinomas in mixed tumors. Despite its positive correlation with p63 expression in carcinomas in mixed tumors ( r = 0.8323, P < .00001), ΔNp63 expression showed a decrease in benign tumors. Positivity for p53 was detected in 2 of 13 and 1 of 19 benign mixed tumors and carcinomas in mixed tumors, respectively. There was no correlation between p63 or ΔNp63 and p53 expression. Our data support the notion that the decrease of p63 expression, in particular of its isoform ΔNp63, seems to be an important factor in the development of carcinomas in mixed tumors.

Colorectal cancer is one of the most commonly incriminated neoplastic pathologies and it has afairly high mortality rate. Although the therapeutic arsenal of rectal cancer has steadily improvedthrough the acquisition of biology, technology and pharmacology, the central role of surgicaltechnique is widely recognized in obtaining local control, on the one hand and a good quality of lifeof operated patient on the other hand. This article is a retrospective analysis of surgical proceduresfor rectal neoplasia conducted in order to determine to what extent technological development andcontinuous improvement of surgical techniques have influenced the evolution of patientmanagement with this pathology. This study was retrospective, observational, descriptive, single-center and it was held in the Department of General Surgery and Emergency III of the UniversityEmergency Hospital Bucharest during 1 January 2007 - March 31, 2016 and included a total of127 patients.

The author of the article analyses the problem of the female emancipation in the little-known feuilleton “Amazonia: A Very Inept Story” (1924) by Mykola Chirsky. The author determines the genre affiliation of the work and examines its compositional structure. Three parts are distinguished in the architectonics of associative feuilleton: associative conception; deployment of a “small” topic; conclusion. The author of the article clarifies the role of intertextual elements and the method of constantly switching the tone from serious to comic to reveal the thematic direction of the work. Mykola Chirsky’s interest in the problem of female emancipation is corresponded to the general mood of the era. The subject of ridicule in provocative feuilleton is the woman’s radical metamorphoses, since repulsive manifestations of emancipation becomes commonplace. At the same time, the writer shows respect for the woman, appreciates her femininity, internal and external beauty, personality. He associates the positive in women with the functions of a faithful wife, a caring mother, and a skilled housewife. In feuilleton, the writer does not bypass the problem of the modern man role in a family, but analyses the value and moral and ethical guidelines of his character. The husband’s bad habits receive a caricatured interpretation in the strange behaviour of relatives. On the one hand, the writer does not perceive the extremes brought by female emancipation, and on the other, he mercilessly criticises the male “virtues” of contemporaries far from the standard. The artistic heritage of Mykola Chirsky remains little studied. The urgent task of modern literary studies is the introduction of Mykola Chirsky’s unknown works into the scientific circulation and their thorough scientific understanding.

Статья посвящена рассмотрению проблем профилактики преступлений оперативными подразделениями исправительных учреждений (далее - ИУ). Автор, раскрывая роль оперативных отделов ИУ в общей профилактике правонарушений, указывает на ее двоякость, поскольку, с одной стороны, рассматриваемые подразделения обладают значительным преимуществом перед другими службами учреждения в выявлении негативных факторов (негласный метод получения оперативно значимой информации), с другой стороны - далеко не все условия, которые способствуют совершению преступлений в ИУ, можно устранить оперативным путем. Изучение специальной литературы позволило выявить в деятельности начальников ИУ определенные проблемы, связанные с оценкой состояния оперативной обстановки в ИУ, сложившейся ситуации; с отсутствием прогноза развития криминогенной ситуации в ИУ, а также с профессиональной некомпетентностью руководителей, неумением объективно оценивать результаты деятельности структурных подразделений. Автор особое внимание уделяет анализу статистических данных о совершенных и предотвращенных преступлениях лицами, находящимися в местах лишения свободы. The article is devoted to the consideration of problems of crime prevention by operational units of correctional institutions (hereinafter referred to as IA). The author, revealing the role of the operational departments of the IA in the general prevention of offences, points to its twofold. On the one hand, the units under consideration have significant advantages over other services of the institution in identifying negative factors (these are tacit methods of obtaining promptly meaningful information). On the other hand, not all conditions conducive to the commission of crimes in IA can be eliminated by operational means: For example, shortcomings in the activities of other departments and services (security department, duty shift, etc.). The study of special literature has made it possible to identify problems in the activities of heads of correctional institutions in the sphere of implementation of solutions in case of lack of objective and complete information on the state of the operational situation in IA, the current situation, the results of the activities of structural subdivisions; No forecast of the development of the crime situation in IE; Professional incompetence of managers, inability to objectively assess the results of activities of structural subdivisions. The author pays particular attention to the analysis of statistics on crimes committed and prevented by persons in detention.

This article examines the role that correspondence played in the accounting systems of Tudor merchants. Merchants relied heavily on letters as a means of controlling their businesses at a distance by making agents accountable. Written accountability, as well as information for business decisions, was encouraged by agency relationships in mercantile enterprises. The system could be undermined by the breakdown of communication through the negligence of a factor or the lack of involvement by the principal. The time delays between the sending and the receipt of letters, on the one hand, and the procurement and conveyance of goods, on the other, were additional problems.

Metaphor And Metonymy

The chapter reports on work concerned with the issue of how conceptual metaphor theory (CMT) functions as a link between culture and cognition. Three large areas are investigated to this effect. First, work on the interaction between conceptual metaphors, on the one hand, and folk and expert theories of emotion, on the other, is surveyed. Second, the issue of metaphorical universality and variation is addressed, together with that of the function of embodiment in metaphor. Third, a contextualist view of conceptual metaphors is proposed. The discussion of these issues leads to a new and integrated understanding of the role of metaphor and metonymy in creating cultural reality and that of metaphorical variation across and within cultures, as well as individuals.

Realism Debate

What is a scientific theory? Is it a set of propositions? Or a family of models? Or is it some kind of abstract artefact? These options are examined in the context of a comparison between theories and artworks. On the one hand, theories are said to be like certain kinds of paintings, in that they play a representational role; on the other, they are compared to musical works, insofar as they can be multiply presented. I shall argue that such comparisons should be treated with care and that all of the above options face problems. Instead, I suggest, we should adopt a form of eliminativism towards theories, in the sense that a theory should not be regarded as any thing. Nevertheless, we can still talk about them and attribute certain qualities to them, where that talk is understood to be made true by certain practices. This shift to practices as truth-makers for theory talk then has certain implications for how we regard theories in the realism debate and in the context of the nature and role of representation in science.

Abstract Liver cell hydration (cell volume) is dynamic and can change within minutes under the influence of hormones, nutrients, and oxidative stress. Such volume changes were identified as a novel and important modulator of cell function. It provides an early example for the interaction between a physical parameter (cell volume) on the one hand and metabolism, transport, and gene expression on the other. Such events involve mechanotransduction (osmosensing) which triggers signaling cascades towards liver function (osmosignaling). This article reviews our own work on this topic with emphasis on the role of β1 integrins as (osmo-)mechanosensors in the liver, but also on their role in bile acid signaling.

Background: Cancer antigen 19-9 (CA 19-9) is a tumor-associated mucin glycoprotein antigen that may be elevated in healthy individuals as well as in patients with benign and malignant tumors. It is useful in the management of pancreatic and other gastrointestinal tumors. CA 19-9 is also elevated in benign and malignant ovarian tumors. Aim: To study the pattern of serum CA19-9 in complex ovarian tumors. Methods: The study design was descriptive, based on data collected from medical records. Patients with a complex ovarian mass, who were investigated with CA 19-9 and had undergone surgery, wereincluded in the study. The study duration was 2 years from January 2014 to December 2015. A total of 273 patients (119 - benign and 154 malignant) with complex ovarian mass and elevated CA 19-9 underwent surgery during the study period. Results: CA 19-9 was elevated in 55 patients (20%). Of these, 23 patients had benign tumors while 32 had malignant tumors.Among patients with benign tumors, 21 had dermoid, 23 had mucinous tumors and 75 had other types of tumors. CA 19-9 was elevated in 10 (47.6%) of the dermoids, 7 (30.4%) of the mucinous tumors and 6 (8%) of the other benign tumors. Among patients with malignant tumors, 138 were epithelial and 16 were non epithelial tumors. Of the epithelial tumors, 31 were mucinous and 107 were non mucinous types. Overall, 29 (21%) had elevated CA 19-9. Of the epithelial tumors, 22.6% of the mucinous type and 20.6% of the non mucinous type had elevated CA 19-9. Among the non-epithelial tumors, 3 (18.8%) had elevated CA19-9. Conclusion: CA 19-9 is elevated in several conditions but most likely to be raised in dermoid cysts and mucinous tumours. CA19-9 levels need to be interpreted along with clinical and radiological findings.

Death is one of the most difficult topics a person can talk about. The human being is busy with how to continue his life and improve its conditions. This study aims is to explore the writing of Facebook pages of the dead. The research used the qualitative approach through a content analysis, where (50) publications were found on fifteen pages of a dead person with an intentional sample, and the results of the research showed that writing people in the pages of the dead included two directions, the first direction is a desire to immortalize the dead and a kind of preserving their roots Alive. As for the other direction, it was weeping over their ruins and showing the end of a person's death and his end life. Sometimes in the same post include both directions together, meaning "the use of the deceased’s account by his family by changing the profile picture of the dead, and at the same time inviting the deceased’s friends through his page to the memorial event. People write on the pages of the dead in order to weep over their ruins on the one hand, and to immortalize their memories on the other side. Facebook as a social platform and the interaction of people with the pages of the dead shows the great social interaction that takes place in this space, and research in this field is not consistent with one and only claim, as some posts are either temporary or permanent; Therefore, I have used screen capture technology to collect and retain information. The pages of the dead included referring to them, writing memorials and longing, etc. Facebook has become a social platform that allows those who lose a dear person to share their grief through it, and enables them to deal with death and relieve their pain
