This book reflects on 'the political' in queer theory and politics by revisiting two of its key categories: hegemony and heteronormativity. It explores the specific insights offered by these ...categories and the ways in which they augment the analysis of power and domination from a queer perspective, whilst also examining the possibilities for political analysis and strategy-building provided by theories of hegemony and heteronormativity. Moreover, in addressing these issues the book strives to rethink the understanding of the term &dquotequeer&dquote, so as to avoid narrowing queer politics to a critique of normative heterosexuality and the rigid gender binary. By looking at the interplay between hegemony and heteronormativity, this ground-breaking volume presents new possibilities of reconceptualizing 'the political' from a queer perspective. Investigating the effects of queer politics not only on subjectivities and intimate personal relations, but also on institutions, socio-cultural processes and global politics, this book will be of interest to those working in the fields of critical theory, gender and sexuality, queer theory, postcolonial studies, and feminist political theory.
How is tolerance reflected in urban space? Which urban actors are involved in the practices and narratives of tolerance? What are the limits of tolerance? The edited volume answers these questions by ...considering different forms of urban in/exclusion and participatory citizenship. By drawing together disparate yet critical writings, Doing Tolerance examines the production of space, urban struggles and tactics of power from an interdisciplinary perspective. Illustrating the paradoxes within diverse interactions, the authors focus on the conflict between heterogeneous groups of the governed, on the one hand, and the governing in urban spaces, on the other. Above all, the volume explores the divergences and convergences of participatory citizenship, as they are revealed in urban space through political, socio-economic and cultural conditions and the entanglements of social mobilities.
The discovery of two-dimensional electron gases (2DEGs) at oxide interfaces-involving electrons in narrow d-bands-has broken new ground, enabling the access to correlated states that are unreachable ...in conventional semiconductors based on s- and p- electrons. There is a growing consensus that emerging properties at these novel quantum wells-such as 2D superconductivity and magnetism-are intimately connected to specific orbital symmetries in the 2DEG sub-band structure. Here we show that crystal orientation allows selective orbital occupancy, disclosing unprecedented ways to tailor the 2DEG properties. By carrying out electrostatic gating experiments in LaAlO3/SrTiO3 wells of different crystal orientations, we show that the spatial extension and anisotropy of the 2D superconductivity and the Rashba spin-orbit field can be largely modulated by controlling the 2DEG sub-band filling. Such an orientational tuning expands the possibilities for electronic engineering of 2DEGs at LaAlO3/SrTiO3 interfaces.
Zika virus (ZIKV) is a flavivirus linked to multiple birth defects including microcephaly, known as congenital ZIKV syndrome. The identification of host factors involved in ZIKV replication may guide ...efficacious therapeutic interventions. In genome-wide transcriptional studies, we found that ZIKV infection triggers aryl hydrocarbon receptor (AHR) activation. Specifically, ZIKV infection induces kynurenine (Kyn) production, which activates AHR, limiting the production of type I interferons (IFN-I) involved in antiviral immunity. Moreover, ZIKV-triggered AHR activation suppresses intrinsic immunity driven by the promyelocytic leukemia (PML) protein, which limits ZIKV replication. AHR inhibition suppressed the replication of multiple ZIKV strains in vitro and also suppressed replication of the related flavivirus dengue. Finally, AHR inhibition with a nanoparticle-delivered AHR antagonist or an inhibitor developed for human use limited ZIKV replication and ameliorated newborn microcephaly in a murine model. In summary, we identified AHR as a host factor for ZIKV replication and PML protein as a driver of anti-ZIKV intrinsic immunity.
Around the world trans and gender diverse people are marginalized and discriminated against in medical, psychological, and nursing care. This anthology is the first to address the current situation ...of this population in various global healthcare settings. The perspectives from 11 different countries give insight into the difficult experiences of the trans and gender diverse community when seeking healthcare, and how self-organized community structures can help to overcome barriers to often inaccessible public healthcare systems. The majority of contributions are written from a lived trans and gender diverse perspective.
Summary
Our aim was to summarize, through a systematic review, the current evidence from dietary intervention and observational studies on the impact of adherence to the Mediterranean diet on ...adiposity markers and obesity in children and adolescents. We searched Medline up to June 1, 2021 for the identification of intervention and observational studies meeting the inclusion criteria, following the PRISMA statement. We included 55 articles: 8 intervention studies and 47 observational studies. Three trials report a beneficial effect of the dietary intervention, whereas two did not, and three did not compare with a control. All observational studies were cross‐sectional, and only five studies also included a longitudinal analysis. More than half of the cross‐sectional studies found no significant association between adherence to Mediterranean diet and adiposity. Three out of the five longitudinal studies found a negative association. The majority of both observational and intervention studies was of low quality. Despite a large number of published studies, overall, there is only limited evidence of a beneficial effect of following a traditional Mediterranean diet to maintain a healthy body weight in childhood. More high‐quality intervention and longitudinal data are needed to form the base of large‐scale health programs to prevent childhood obesity.
The analysis of perfluoroalkyl substances (PFASs) and organophosphate flame retardants (PFRs) in the different environmental compartments of a characteristic coastal wetland, the Albufera Natural ...Park (Valencia, Spain), is required for understanding the transport, accumulation and fate of these pollutants in an area under high anthropogenic pressure. Samples included 13 wastewater treatment plant influents, 13 effluents, 12 surface water, 19 sediment samples and 10 fish individuals from the Albufera Natural Park and the surrounding area. Tris(2-chloroisopropyl) phosphate (TCIPP) and perfluorooctane sulfonate (PFOS) were at the highest concentrations in water, 330.2 ng L−1 and 47.8 ng L−1, respectively. In fish and sediment PFOS was also the most detected while perfluorooctanoic acid (PFOA) was in all types of water. Higher levels of target compounds (mainly PFASs) in wastewater effluents compared to influent suggested both, formation from precursors during treatment and poor removal efficiency. Mean levels of PFOS in water and fish were higher than the environmental quality standards (EQS) established by the European Union Directive 2013/39/EU. The influence of the metropolitan area of Valencia and its surrounding industrial belt could explain the significantly higher levels reported in the northern part (influenced by the Turia River).

•21 PFASs and 9 PFRs were quantified in sediment, water and fish from a wetland area.•TCIPP and PFOS were the predominant compounds detected in all the samples.•Mean levels of PFOS in water and fish were higher than the annual average EQS.•High levels of PFASs from different sources were observed in wastewater effluents.
Objective
The prevalence of depressive symptoms immediately after the diagnosis of colorectal cancer (CRC) is high and has important implications both psychologically and on the course of the ...disease. The aim of this study is to analyse the association between depressive symptoms and CRC survival at 5 years after diagnosis.
Methods
This multicentre, prospective, observational cohort study was conducted on a sample of 2602 patients with CRC who completed the Hospital Anxiety and Depression Scale (HADS‐D) at 5 years of follow‐up. Survival was analysed using the Kaplan–Meier method and Cox regression models.
Results
According to our analysis, the prevalence of depressive symptoms after a CRC diagnosis was 23.8%. The Cox regression analysis identified depression as an independent risk factor for survival (HR = 1.47; 95% CI: 1.21–1.8), a finding which persisted after adjusting for sex (female: HR = 0.63; 95% CI: 0.51–0.76), age (>70 years: HR = 3.78; 95% CI: 1.94–7.36), need for help (yes: HR = 1.43; 95% CI: 1.17–1.74), provision of social assistance (yes: HR = 1.46; 95% CI: 1.16–1.82), tumour size (T3–T4: HR = 1.56; 95% CI: 1.22–1.99), nodule staging (N1–N2: HR = 2.46; 95% CI: 2.04–2.96), and diagnosis during a screening test (yes: HR = 0.71; 95% CI: 0.55–0.91).
Conclusions
There is a high prevalence of depressive symptoms in patients diagnosed with CRC. These symptoms were negatively associated with the survival rate independently of other clinical variables. Therefore, patients diagnosed with CRC should be screened for depressive symptoms to ensure appropriate treatment can be provided.
In the pursuit of controlling the heat exposure mediated by magnetic nanoparticles, we provide new guidelines for tailoring magnetic relaxation processes via dipolar interactions. For this purpose, ...highly crystalline and monodisperse magnetic iron oxide nanocrystals whose sizes range from 7 to 22 nm were synthesized by thermal decomposition of iron organic precursors in 1-octadecene. The as-synthesized nanoparticles are soft nanomagnets, showing superparamagnetic-like behavior and SAR values which progressively increase with particle size, field frequency, and amplitude up to 3.6 kW/gFe. Our data show the influence of media viscosity, particle size, and concentration on dipolar interactions and consequently on the magnetic relaxation processes related to the heat release. Understanding the role of dipolar interactions is of great importance toward the use of iron oxide nanoparticles as efficient hyperthermia mediators.
•Physicochemical and sensory parameters of honeys were studied.•Differences were found in colour, conductivity and sucrose among different regions.•The cluster analysis showed a grouping pattern in ...relation to the geographic region.•The honeys analysed comply with national and international regulations.
The physicochemical parameters (moisture, hydroxymethyl furfural, colour, electrical conductivity, free acidity, glucose, fructose and sucrose) and the sensory properties(aroma, taste, appeareance, texture) were determined in honeys from apiaries of the agricultural, hills and meadow zones of the south east region of Buenos Aires province (Argentina). The analysis of variance showed significant differences among zones in the mean value of hydroximethyl furfural, colour, electrical conductivity and sucrose content. The principal component analysis explained the 70% of the variance among samples with the first two principal components in both cases. The cluster analysis and linear discriminant analysis showed that samples were grouped in relation to the sampling region coinciding with the results of the principal component analysis. Results suggest that could be possible to classify honeys according to the geographic origin based on the physicochemical parameters; however, the sensory properties were not good predictors.
