Osteoarthritis (OA) is a condition with high prevalence worldwide. OA affects not only the articular cartilage, but the entire joint, including the subchondral bone, ligaments, capsule, synovial membrane and the periarticular muscles. Despite the fact that the risks associated with OA increase with age, it is not a part of the natural aging process. It typically involves the knee, hip, spine, hand and foot joints. Several factors play an important role in the pathogenesis of OA, including biomechanical factors, proinflammatory mediators and proteases. On the other hand, it was mostly the results of the studies conducted on the genetic, genomic and epigenetic aspects of OA, from among many of its underlying etiological factors, which shed light on the molecular processes involved in the etiopathogenesis of OA. As the mechanisms that cause joint tissue damage in OA come to light, the treatment of OA will go beyond just providing symptomatic relief. Consequentially, new treatments will emerge that will either slow or completely stop the progression of OA.

As more and more people face mobility constraints due to the natural aging process of the population, barrier-free planning becomes an important urban planning issue. It is elemental to know the place of spatial barriers associated with the negative emotion - the “stress” of probands. To achieve this, a method of psycho-physiological monitoring was developed, using a special technical device to measure autonomic bodily functions as indicators for emotions - a Smartband. This chapter presents the main characteristics and the outcomes of two projects that have applied the method, one in Germany and the other in Brazil. Future research directions are also discussed in this chapter. In summary, the next steps are to automate the interpretation of the collected data and to combine the existing methods with the development of a smartphone-based app to allow people to give some qualitative hints about urban parameters.

This article aims to clarify the question of speed and intensity in the thoughts of Simondon and Deleuze, in order to shed light on the recent debates regarding accelerationism and its politics. Instead of starting with speed, we propose to look into the notion of intensity and how it serves as a new ontological ground in Simondon's and Deleuze's philosophy and politics. Simondon mobilises the concept of intensity to criticise hylomorphism and substantialism; Deleuze, taking up Simondon's conceptual framework, repurposes it for his ontology of difference, elevating intensity to the rank of generic concept of being, thus bypassing notions of negativity and individuals as base, in favour of the productive and universal character of difference. In Deleuze, the correlation between intensity and speed is fraught with ambiguities, with each term threatening to subsume the other; this rampant tension becomes explicitly antagonistic when taken up by the diverse strands of contemporary accelerationism, resulting in two extreme cases in the posthuman discourse: either a pure becoming, achieved through destruction, or through abstraction that does away with intensity altogether; or an intensity without movement or speed, that remains a pure jouissance. Both cases appear to stumble over the problem of individuation, if not disindividuation. Hence, we wish to raise the following question: in what way can one think of an accelerationist politics with intensity, or an intensive politics without the fetishisation of speed? We consider this question central to the interrogation of the limits of acceleration and posthuman discourse, thus requiring a new philosophical thought on intensity and speed.

The treatment of ulcerative colitis (UC) has changed over the last decade. It is extremely important to optimize the therapies which are available nowadays and commonly used in daily clinical practice, as well as to stimulate the search for more powerful drugs for the induction and maintenance of sustained and durable remission, thus preventing further complications. Therefore, it is mandatory to identify the patients' prognostic variables associated with an aggressive clinical course and to test the most potent therapies accordingly.To date, the conventional therapeutic approach based on corticosteroids, salicylates (sulfasalazine, 5-aminosalicylic acid) or immunosuppressive agents is commonly used as a first step to induce and to maintain remission. However, in recent years, knowledge of new pathogenetic mechanisms of ulcerative colitis have allowed us to find new therapeutic targets leading to the development of new treatments that directly target proinflammatory mediators, such as TNF-alpha, cytokines, membrane migration agents, cellular therapies.The aim of this review is to provide the most significant data regarding the therapeutic role of drugs in UC and to give an overview of biological and experimental drugs that will become available in the near future. In particular, we will analyse the role of these drugs in the treatment of acute flare and maintenance of UC, as well as its importance in mucosal healing and in treating patients at a high risk of relapse.

The literature of the Italian Due- and Trecento frequently calls into play the figure of a woman reader. From Guittone d’Arezzo’s piercing critic, the ‘villainous woman’, to the mysterious Lady who bids Guido Cavalcanti to write his grand philosophical song, to Dante’s female co-editors in the Vita Nova and his great characters of female readers, such as Francesca and Beatrice in the Comedy, all the way to Boccaccio’s overtly female audience, this particular sort of interlocutor appears to be central to the construct of textuality and the construction of literary authority in these times. The aim of this book is to shed light on this figure by contextualizing her within the history of female literacy, the material culture of the book, and the ways in which writers and poets of earlier traditions (in particular Occitan and French) imagined her. Its argument is that these figures of women readers are not mere veneers between a male author and a ‘real’ male readership, but that, although fictional, they bring several advantages to their vernacular authors, such as orality, the mother tongue, the recollection of the delights of early education, literality, freedom in interpretation, absence of teleology, the beauties of ornamentation and amplification, a reduced preoccupation with the fixity of the text, the pleasure of making mistakes, dialogue with the other, the extension of desire, original simplicity, and new and more flexible forms of authority.

The current study intends to contribute to a better understanding of the medical tourism experience. In particular, this study uses data from a survey-based study conducted on a sample of 1,209 medical tourists in Croatia. On the one hand, this study aims to explore and shed light on the decision-making process of medical tourists, and, on the other hand, to reveal which elements of both the medical institution and the destination where it is located, have largest potentials to drive medical tourist delight and/or frustration, in accordance with the three-factor theory of customer satisfaction.

Starting from previous studies in professional caregivers of people with dementia and other diseases in institutionalized centers of different regions, the aim of this study was to compare burnout levels that workers present depending on the center, to create a caregiver profile with high professional accomplishment and to describe the quality of life that residents perceive Murcia and Barcelona. The instruments used were the Maslach Burnout Inventory (MBI), the Professional Caregiver Survey developed ad hoc and the Brief Questionnaire of Quality of Life (CUBRECAVI in Spanish) on residents. The results show, on the one hand, that levels of professional accomplishment may be paradoxically higher in the case of catastrophe and, on the other hand, the 98.2% of users are satisfied with the residence in which is located and 81.8% with the manner in which occupy the time. The conclusions that are extrapolated from the study shed light on the current situation of workers and residents and the influence that an earthquake can have on them.

“Tell a man today to go and build a state,” Samuel Finer once stated, “and he will try to establish a definite and defensible boundary and compel those who live inside it to obey him.” While at best an oversimplification, Finer's insight illuminates an interesting aspect of state-society relations. Who is it that builds the state? How and where do they establish territorial boundaries, and how are those who live within that territory compelled to obey? Generally speaking, these are the questions that will be addressed here. Of more immediate concern is the fate of peoples located in regions where arbitrary land boundaries fall. Are they made loyal to the state through coercion or by their own compulsions? More importantly, how are their identities shaped by the efforts of the state to differentiate them from their compatriots on the other side of the borders? How is the shift from ethnic to national identities undertaken? A parallel elaboration of the national histories of the populations of Karelia and Moldova will shed light on these questions. The histories of each group are marked by a myriad of attempts to differentiate the identity of each ethnic community from their compatriots beyond the state's borders. The results of such overt, state-initiated efforts to differentiate borderland populations by encouraging a national identity at the expense of the ethnic, has ranged from the mundane to the tragic—from uneventful assimilation to persecution and even genocide. As an illustration of the range of possibilities and processes, I maintain that the tragedies of Karelia and Moldova are not exceptional, but rather are a consequence of their geographical straddling of arbitrary borders, and the need for the state to promote a distinctive national identity for these populations to differentiate them socially from their compatriots beyond the frontier.

There is a type of riddle that Bar-Hillel, Noah and Frederick (2018) call “stumpers”. A stumper is a riddle which is initially intractable because the mental model or representation of the situation described in the riddle does not contain the vital information which is required to solve it. The Cognitive Reflection Task (CRT; Frederick, 2005) on the other hand relies on seemingly completely different cognitive processes. However, exploratory work from Bar-Hillel et al. (2019) suggests that success on stumpers correlates with performance on the CRT. This finding may shed light on the cognitive processes underlying both the resolution of stumpers and the CRT. We replicated the work from Bar-Hillel et al. (2019) suggesting a relationship between performance on the CRT and performance on stumpers as well as extending this to show a relationship between performance on the CRT-v. This may point to the underexplored importance of suppression in solving stumpers and traditional riddles.

Summary The research answers a problem related to family relations in terms of resorting to customs in alimony, housing, clothing, and others...which results in disputes that may lead to some of them in the courts and may end in divorce. The aim of the research was to 1 - presenting a knowledge system related to the semantics of the good-natured in order to contribute to reshaping a mature mentality of the spouses that controls the relationship between them in the event of disagreement. 2 - and to shed light on the dimensions and limits of what is textually known and what is known by convention in the family. 3 - Emphasis on that good practice is mutual. Between both husband and wife, this assignment is not limited to one without the other. The inductive approach was adopted by collecting the relevant Qur’anic verses and mentioning the sayings of the commentators and jurists, the analytical approach in understanding the semantics of the words and the directives of the interpreters, and the deductive approach in order to reach comprehensive controls that serve the general objective of the research, and the research ended with a set of results and recommendations, including: Considering the custom that does not contradict A legal text is one of the considered rules in controlling relations between spouses. Provided that it falls under the husband’s ability and energy, and that it is something that has spread among people, and applies to the family like him. The Noble Qur’an - Ten Laws - Family Relationship - Rights between spouses - Custom and its effect between spouses.

This article first aims to demonstrate the different ways the work of the English neurologist John Hughlings Jackson influenced Freud. It argues that these can be summarized in six points. It is further argued that the framework proposed by Jackson continued to be pursued by twentieth-century neuroscientists such as Papez, MacLean and Panksepp in terms of tripartite hierarchical evolutionary models. Finally, the account presented here aims to shed light on the analogies encountered by psychodynamically oriented neuroscientists, between contemporary accounts of the anatomy and physiology of the nervous system on the one hand, and Freudian models of the mind on the other. These parallels, I will suggest, are not coincidental. They have a historical underpinning, as both accounts most likely originate from a common source: John Hughlings Jackson's tripartite evolutionary hierarchical view of the brain.
