Colour terms in five linguistic images of the world: the semantic perspective

Social and cultural factors shape the linguistic perception of colour. At the same time, colour terms co-create the linguistic image of the world, which allows us to interpret reality and profile our statements and beliefs. This paper presents six basic colour terms: white, black, red, green, yellow, and blue (both as adjectives and as nouns) in the five different linguistic images of the world of the following languages: English, French, Italian, Polish, and Japanese. The methodological framework is based on cultural linguistics theory and the basis of semantics. The study explores denotative and connotative meanings of colour terms with their collocations. The data gathered from monolingual, bilingual, collocation, and phraseological dictionaries is analysed from the lexical-semantic point of view. The paper discusses semantic differences between contrasting cultures, especially in the blue-green and red lexis. Simultaneously, the findings point to transcultural and global aspects of colour meanings. Both the contexts of cultural diversity and of geographic location are emphasised in the colour semantics. Colours as linguistic signs can specify and categorise reality in terms of feelings, mental attitudes, or sensual reactions. The examined words also refer to location, nature, and the human body. The study shows that colour terms are multifunctional units in the linguistic image of the world, both in terms of the analysed languages separately and as an illustration of the cultural community of different ethnic languages

Immune responses and clinical outcomes after COVID-19 vaccination in patients with liver disease and liver transplant recipients

Background &amp; Aims: Comparative assessments of immunogenicity following different COVID-19 vaccines in patients with distinct liver diseases are lacking. SARS-CoV-2-specific T-cell and antibody responses were evaluated longitudinally after one to three vaccine doses, with long-term follow-up for COVID-19-related clinical outcomes. Methods: A total of 849 participants (355 with cirrhosis, 74 with autoimmune hepatitis [AIH], 36 with vascular liver disease [VLD], 257 liver transplant recipients [LTRs] and 127 healthy controls [HCs]) were recruited from four countries. Standardised immune assays were performed pre and post three vaccine doses (V1-3). Results: In the total cohort, there were incremental increases in antibody titres after each vaccine dose (p &lt;0.0001). Factors associated with reduced antibody responses were age and LT, whereas heterologous vaccination, prior COVID-19 and mRNA platforms were associated with greater responses. Although antibody titres decreased between post-V2 and pre-V3 (p = 0.012), patients with AIH, VLD, and cirrhosis had equivalent antibody responses to HCs post-V3. LTRs had lower and more heterogenous antibody titres than other groups, including post-V3 where 9% had no detectable antibodies; this was heavily influenced by intensity of immunosuppression. Vaccination increased T-cell IFNγ responses in all groups except LTRs. Patients with liver disease had lower functional antibody responses against nine Omicron subvariants and reduced T-cell responses to Omicron BA.1-specific peptides compared to wild-type. 122 cases of breakthrough COVID-19 were reported of which 5/122 (4%) were severe. Of the severe cases, 4/5 (80%) occurred in LTRs and 2/5 (40%) had no serological response post-V2. Conclusion: After three COVID-19 vaccines, patients with liver disease generally develop robust antibody and T-cell responses to vaccination and have mild COVID-19. However, LTRs have sustained no/low antibody titres and appear most vulnerable to severe disease. Impact and implications: Standardised assessments of the immune response to different COVID-19 vaccines in patients with liver disease are lacking. We performed antibody and T-cell assays at multiple timepoints following up to three vaccine doses in a large cohort of patients with a range of liver conditions. Overall, the three most widely available vaccine platforms were immunogenic and appeared to protect against severe breakthrough COVID-19. This will provide reassurance to patients with chronic liver disease who were deemed at high risk of severe COVID-19 during the pre-vaccination era, however, liver transplant recipients had the lowest antibody titres and remained vulnerable to severe breakthrough infection. We also characterise the immune response to multiple SARS-CoV-2 variants and describe the interaction between disease type, severity, and vaccine platform. These insights may prove useful in the event of future viral infections which also require rapid vaccine development and delivery to patients with liver disease.</p

A Potential New Pathway for Staphylococcus aureus Dissemination: The Silent Survival of S. aureus Phagocytosed by Human Monocyte-Derived Macrophages

Although considered to be an extracellular pathogen, Staphylococcus aureus is able to invade a variety of mammalian, non-professional phagocytes and can also survive engulfment by professional phagocytes such as neutrophils and monocytes. In both of these cell types S. aureus promptly escapes from the endosomes/phagosomes and proliferates within the cytoplasm, which quickly leads to host cell death. In this report we show that S. aureus interacted with human monocyte-derived macrophages in a very different way to those of other mammalian cells. Upon phagocytosis by macrophages, S. aureus persisted intracellularly in vacuoles for 3–4 days before escaping into the cytoplasm and causing host cell lysis. Until the point of host cell lysis the infected macrophages showed no signs of apoptosis or necrosis and were functional. They were able to eliminate intracellular staphylococci if prestimulated with interferon-γ at concentrations equivalent to human therapeutic doses. S. aureus survival was dependent on the alternative sigma factor B as well as the global regulator agr, but not SarA. Furthermore, isogenic mutants deficient in α-toxin, the metalloprotease aureolysin, protein A, and sortase A were efficiently killed by macrophages upon phagocytosis, although with different kinetics. In particular α-toxin was a key effector molecule that was essential for S. aureus intracellular survival in macrophages. Together, our data indicate that the ability of S. aureus to survive phagocytosis by macrophages is determined by multiple virulence factors in a way that differs considerably from its interactions with other cell types. S. aureus persists inside macrophages for several days without affecting the viability of these mobile cells which may serve as vehicles for the dissemination of infection

Feminism and art: unexpected encounters

Since the revolutions of the 1960s, feminism and art have created spaces for thinking and rethinking the links between gender and creativity. Art has been challenged both within and without the frame, as artists and feminists disrupt and complicate pre-established modes of production and representation

Abakans: Revolutionary Art for the Past, Present, and Future

Abakans emerged in the 1960s in the Eastern Bloc and made Magdalena Abakanowicz famous beyond the Iron Curtain. The purpose of this article is to present a contemporary art framework for reassessing and reviving the revolutionary capacities of Abakans. To do that, the article asks what makes Abakans revolutionary art? What makes them groundbreakers and what makes them path-makers? What blueprint have we (contemporary artists) inherited (knowingly or unknowingly) from Abakans for responding to the revolutionary new phase of the planet\u27s cycle, the Anthropocene? In response to these questions, the article is divided into three sections based on the past, present, and future through which the author\u27s personal reflections entwine with artistic, theoretical, cultural, economic, ecological, spiritual, and socio-political contexts. What arises is that Abakans are one of the most original radical bodies of work of the twentieth century that offer forward-looking strategies for recuperating the damaged planet
