Abstract A wealth of rapidly evolving reports suggests that olfaction and taste disturbances may be manifestations of the novel COVID-19 pandemic. While otolaryngological societies worldwide have started to consider chemosensory evaluation as a screening tool for COVID-19 infection, the true nature of the relationship between the changes in chemosensory ability and COVID-19 is unclear. Our goal with this review is to provide a brief overview of published and archived literature, as well as the anecdotal reports and social trends related to this topic up to April 29, 2020. We also aim to draw parallels between the clinical/chemosensory symptomology reported in association to past coronavirus pandemics (such as SARS and MERS) and the novel COVID-19. This review also highlights current evidence on persistent chemosensory disturbances after the infection has resolved. Overall, our analysis pinpoints the need for further studies: (1) to better quantify olfaction and taste disturbances associated with SARS-CoV-2 infection, compared to those of other viral and respiratory infections, (2) to understand the relation between smell, taste, and chemesthesis disturbances in COVID-19, and (3) to understand how persistent are these disturbances after the infection has resolved.

The emergence of pachychoroid disease is changing the concept of age-related macular degeneration (AMD). The concept of pachychoroid diseases was developed through clinical observation of multimodal images of eyes with AMD and central serous chorioretinopathy; however, recent genetic studies have provided a proof of concept for pachychoroid spectrum disease, which should be differentiated from drusen-driven AMD. The genetic confirmation of pachychoroid concept further provides novel viewpoints to decode previously reported findings, which facilitates an understanding of the true nature of pachychoroid diseases and AMD. The purpose of this review was to elucidate the relationship between pachychoroid diseases and AMD by interpreting previous findings on pachychoroid diseases and AMD from the novel viewpoints of genetic associations. We confirmed that previous genetic studies supported the concept of pachychoroid diseases. From a genetic viewpoint, the presence of thick choroid and the presence of choroidal vascular hyperpermeability were important characteristics of pachychoroid spectrum diseases. Previous studies have also suggested the classification of polypoidal choroidal vasculopathy (PCV) into two subtypes, pachychoroid neovasculopathy and drusen-driven PCV. Genetic viewpoints will be beneficial to rearrange subtypes of drusen-driven AMD and pachychoroid spectrum diseases. Further genetic studies are needed to investigate pachyvessels, pachydrusen and the significance of polypoidal lesions in pachychoroid neovasculopathy and drusen-driven AMD/PCV.

Background: Since its initial description in December 2019 in Wuhan, China, coronavirus disease 2019 (COVID-19) has rapidly progressed into a worldwide pandemic, which has affected millions of lives. Unlike the disease in adults, the vast majority of children with COVID-19 have mild symptoms and are largely spared from severe respiratory disease. However, thereare children who have significant respiratory disease, and some may develop a hyperinflammatory response similar to thatseen in adults with COVID-19 and in children with Kawasaki disease (KD), which has been termed multisystem inflammatory syndrome in children (MIS-C).Objective: The purpose of this report was to examine the current evidence that supports the etiopathogenesis of COVID-19 in children and the relationship of COVID-19 with KD and MIS-C as a basis for a better understanding of the clinical course, diagnosis, and management of these clinically perplexing conditions.Results: The pathogenesis of COVID-19 is carried out in two distinct but overlapping phases of COVID-19: the first triggered by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) itself and the second by the host immune response. Children with KD have fewer of the previously described COVID-19–associated KD features with less prominent acute respiratory distress syndrome and shock than children with MIS-C.Conclusion: COVID-19 in adults usually includes severe respiratory symptoms and pathology, with a high mortality. Ithas become apparent that children are infected as easily as adults but are more often asymptomatic and have milder diseasebecause of their immature immune systems. Although children are largely spared from severe respiratory disease, they canpresent with a SARS-CoV-2–associated MIS-C similar to KD.

This booklet is a collection of the position statements accepted for the HRI’20 conference workshop “Social Cognition for HRI: Exploring the relationship between mindreading and social attunement in human-robot interaction” (Wykowska, Perez-Osorio & Kopp, 2020). Unfortunately, due to the rapid unfolding of the novel coronavirus at the beginning of the present year, the conference and consequently our workshop, were canceled. On the light of these events, we decided to put together the positions statements accepted for the workshop. The contributions collected in these pages highlight the role of attribution of mental states to artificial agents in human-robot interaction, and precisely the quality and presence of social attunement mechanisms that are known to make human interaction smooth, efficient, and robust. These papers also accentuate the importance of the multidisciplinary approach to advance the understanding of the factors and the consequences of social interactions with artificial agents.

Background: Oleanolic Acid (OA) is a ubiquitous product of triterpenoid compounds. Due to its inexpensive availability, unique bioactivities, pharmacological effects and non-toxic properties, OA has attracted tremendous interest in the field of drug design and synthesis. Furthermore, many OA derivatives have been developed for ameliorating the poor water solubility and bioavailability. Objective: Over the past few decades, various modifications of the OA framework structure have led to the observation of enhancement in bioactivity. Herein, we focused on the synthesis and medicinal performance of OA derivatives modified on A-ring. Moreover, we clarified the relationship between structures and activities of OA derivatives with different functional groups in A-ring. The future application of OA in the field of drug design and development also was discussed and inferred. Conclusion: This review concluded the novel achievements that could add paramount information to the further study of OA-based drugs.

: Cryptogenic stroke and its relation to the Patent Foramen Ovale (PFO) is a long-debated topic. Recent clinical trials have unequivocally established the relationship between cryptogenic strokes and paradoxical embolism across the PFO. This slit-like communication exists in everyone before birth, but most often closes shortly after birth. PFO may persist as a narrow channel of communication between the right and left atria in approximately 25-27% of adults. : In this review, we examine the clinical relevance of the PFO with analysis of the latest trials evaluating catheter-based closure of PFO’s for cryptogenic stroke. We also review the current evidence examining the use of antiplatelet medications versus anticoagulants for stroke prevention in those patients with PFO who do not qualify for closure per current guidelines.

This chapter studies the novels of sensibility in the 1780s. The philosophy of John Locke, Anthony Ashley Cooper, third Earl of Shaftesbury, Adam Smith, and Francis Hutcheson had influenced the first wave of epistolary novels of sensibility beginning in the 1740s. These explored the interaction between emotion and reason in producing moral actions. Response to stimuli was minutely examined, especially the relationship between the psychological and physiological manifestations of feelings. Later in the century, and, in particular during the late 1780s when the novel enjoyed a surge in popularity, the capacity for fine feeling became increasingly valued for its own sake rather than moralized. Ultimately, sensibility should be seen as a long-lasting literary movement rather than an ephemeral fashion. It put paternal authority and conventional modes of masculinity under question.

‘It's the masters as has wrought this woe; it's the masters as should pay for it.’ Set in Manchester in the 1840s - a period of industrial unrest and extreme deprivation - Mary Barton depicts the effects of economic and physical hardship upon the city's working-class community. Paralleling the novel's treatment of the relationship between masters and men, the suffering of the poor, and the workmen's angry response, is the story of Mary herself: a factory-worker's daughter who attracts the attentions of the mill-owner's son, she becomes caught up in the violence of class conflict when a brutal murder forces her to confront her true feelings and allegiances. Mary Barton was praised by contemporary critics for its vivid realism, its convincing characters and its deep sympathy with the poor, and it still has the power to engage and move readers today. This edition reproduces the last edition of the novel supervised by Elizabeth Gaskell and includes her husband's two lectures on the Lancashire dialect.

This chapter examines the relationship between entrepreneurs and the communities in which they are embedded. It argues that the actions of entrepreneurs and their firms are contextually situated in specific geographies that make their actions endogenous in the development of place and define a place-specific institutional logic. This argument is at odds with the view that industry clustering is due to the role of incumbent firms. This chapter reconciles these views by adopting a temporal view, allowing both incumbents and geography to co-occur and influence clustering. It then considers the current evidence of entrepreneurs’ effects on regional resources and capacity, and concludes with suggestions for future research.

This chapter approaches police records as a genre that gains from being considered in its relationships with other genres of writing. In particular, we will follow its long-standing relationship to detective fiction, the novel, and biography. Going further, the chapter emphasizes the intermedia character of police records not just in our time but also throughout their existence, indeed from their very origins. This approach opens to a more inclusive media history of police files. We will start with an analysis of the seminal late nineteenth-century French manuals prescribing the writing of a police file, the famous Bertillon-method manuals. We will then track their influence following their adoption nationally and internationally, with particular attention to the politics of their adoption in the colonies. We will also touch briefly on the relationship of early policing to other disciplines, such as anthropology and statistics, before moving to a closer look at its intersections with photography and literature.
