Gender and geography: World views and practices

In introducing this theme issue on international directions in gender studies in geography, we take up three cross-cutting issues. First, we examine the importance of context in shaping where, why, how and by whom gender research is carried out, noting the importance of the representation of women in the profession, the place of geography within the social sciences, and the implications of political and economic contexts. Second, we review theoretical and methodological directions and empirical emphases. Third, we take up the politics of Anglo-American and English-language hegemonies in research publications, recognizing that hegemonies are internally as well as externally created. We suggest practices that could foster scholarship that is more inclusive intellectually and politically. We advocate theorizing that interrogates how “diversity” and “difference” are imagined; we argue for promoting both specialist research as well as the “mainstreaming” of gender perspectives; and we suggest ways of challenging the notion that English-language publications are synonymous with international prestige and value.En introduisant le thème des divergences internationales sur les études de genre en géographie, nous prenons en considération trois points qui se recoupent. Premièrement, nous examinons l’importance du contexte qui explique où, pourquoi, comment et par qui est effectuée la recherche sur les genres. Nous faisons particulièrement attention à l’importance de la représentation des femmes dans la profession, la place de la géographie dans les sciences sociales et les implications des contextes politiques et économiques. Deuxièmement, nous passons en revue les directions théoriques et méthodologiques ainsi que les principales études empiriques. Troisièmement, nous considérons les politiques des hégémonies anglo-américaines et anglophones dans les publications, tout en reconnaissant que ces hégémonies sont créées à la fois intérieurement et extérieurement. Nous proposons ensuite des pratiques qui soutiendraient une connaissance qui soit plus inclusive intellectuellement et politiquement. Nous préconisons une théorisation qui s’interroge sur la manière dont la “diversité” et la “différence” sont imaginées et nous encourageons autant la recherche spécialisée que les perspectives des “courants dominants” sur les études de genres. Enfin, nous soulignons plusieurs points qui défient l’idée que les publications dans des revues de langue anglaise sont synonymes de prestige international et de qualité

HIV-Related Sexual Risk among African American Men Preceding Incarceration: Associations with Support from Significant Others, Family, and Friends

We evaluated the association between social support received from significant others, family, and friends and HIV-related sexual risk behaviors among African American men involved in the criminal justice system. Project DISRUPT is a cohort study among African American men released from prison in North Carolina (N = 189). During the baseline (in-prison) survey, we assessed the amount of support men perceived they had received from significant others, family, and friends. We measured associations between low support from each source (<median value) and participants' sex risk in the 6 months before incarceration. Low levels of social support from significant others, family, or friends were associated with poverty and homelessness, mental disorders, and substance use. Adjusting for age, poverty, and other sources of support, perceiving low support from significant others was strongly associated with multiple partnerships (fully adjusted odds ratio (OR) 2.64, 95% confidence interval (CI) 1.29-5.42). Low significant other support also was strongly associated with sex trade involvement when adjusting for age and poverty status (adjusted OR 3.51, 95% CI 1.25-9.85) but further adjustment for low family and friend support weakened the association (fully adjusted OR 2.81, 95% CI 0.92-8.55). Significant other support was not associated with other sex risk outcomes including concurrent partnerships, anal sex, or sex with an STI/HIV-infected partner. Low family support was associated with multiple partnerships in analyses adjusting for age and poverty (adjusted OR 1.98, 95% CI 1.05-3.76) but the association weakened and was no longer significant after adjusting for other sources of support (fully adjusted OR 1.40, 95% CI 0.65-3.00); family support was not correlated with other risk behaviors. Friend support was not significantly associated with sex risk outcomes. Indicators of overall support from any source were not associated with sex risk outcomes. Helping inmates maintain ties may improve economic security and well-being during community re-entry, while supporting and strengthening relationships with a significant other in particular may help reduce sex risk. Studies should evaluate the protective effects of distinct support sources to avoid masking effects of support and to best understand the influence of social support on health

Complement peptide receptors in GtoPdb v.2023.1

Complement peptide receptors (nomenclature as agreed by the NC-IUPHAR subcommittee on Complement peptide receptors [113]) are activated by the endogenous ~75 amino-acid anaphylatoxin polypeptides C3a and C5a, generated upon stimulation of the complement cascade. C3a and C5a exert their functions through binding to their receptors (C3a receptor, C5a receptor 1 and C5a receptor 2), causing cell recruitment and triggering cellular degranulation that contributes to local inflammation

Hypermethylation of the alternative AWT1 promoter in hematological malignancies is a highly specific marker for acute myeloid leukemias despite high expression levels

Background: Wilms tumor 1 (WT1) is over-expressed in numerous cancers with respect to normal cells, and has either a tumor suppressor or oncogenic role depending on cellular context. This gene is associated with numerous alternatively spliced transcripts, which initiate from two different unique first exons within the WT1 and the alternative (A) WT1 promoter intervals. Within the hematological system, WT1 expression is restricted to CD34+/ CD38- cells and is undetectable after differentiation. Detectable expression of this gene is an excellent marker for minimal residual disease in acute myeloid leukemia (AML), but the underlying epigenetic alterations are unknown. Methods: To determine the changes in the underlying epigenetic landscape responsible for this expression, we characterized expression, DNA methylation and histone modification profiles in 28 hematological cancer cell lines and confirmed the methylation signature in 356 cytogenetically well-characterized primary hematological malignancies. Results: Despite high expression of WT1 and AWT1 transcripts in AML-derived cell lines, we observe robust hypermethylation of the AWT1 promoter and an epigenetic switch from a permissive to repressive chromatin structure between normal cells and AML cell lines. Subsequent methylation analysis in our primary leukemia and lymphoma cohort revealed that the epigenetic signature identified in cell lines is specific to myeloid-lineage malignancies, irrespective of underlying mutational status or translocation. In addition to being a highly specific marker for AML diagnosis (positive predictive value 100%; sensitivity 86.1%; negative predictive value 89.4%), we show that AWT1 hypermethylation also discriminates patients that relapse from those achieving complete remission after hematopoietic stem cell transplantation, with similar efficiency to WT1 expression profiling. Conclusions: We describe a methylation signature of the AWT1 promoter CpG island that is a promising marker for classifying myeloid-derived leukemias. In addition AWT1 hypermethylation is ideally suited to monitor the recurrence of disease during remission in patients undergoing allogeneic stem cell transfer

'Stuff it': Respectability and the voice of resistance in letter to brezhnev

Exploring Letter to Brezhnev through concepts of respectability as feminine cultural capital this article suggests that the film’s affective impulse stems from its representation of a female, working class experience under Thatcherism. This experience is articulated through two structures of feeling derived from the intersecting conventions of social realism, and the consumerist and romantic tropes of the ‘woman’s film’. Through this intersection the daily abjection of women through degrading work or unemployment is traced, whilst being counterpointed to the escapist pleasures of a ‘night out’ constituted through the spatial and aesthetic shifts of the narrative, and the feminisation of the ‘jack the lad’ staple of British screen culture. In this way, Letter to Brezhnev exposes the centrality of respectability to women’s social mobility, or lack of it, thus offering a powerful critique of Thatcherite ideologies and women’s position as primary consumers within them. The article also offers a corrective to existing scholarship that has focussed on cinematic representations of a crisis of masculinity under Thatcherism to the neglect of its corrosive impact on feminine respectability

Human Oocyte-derived Methylation Differences Persist In The Placenta Revealing Widespread Transient Imprinting

Thousands of regions in gametes have opposing methylation profiles that are largely resolved during the post-fertilization epigenetic reprogramming. However some specific sequences associated with imprinted loci survive this demethylation process. Here we present the data describing the fate of germline-derived methylation in humans. With the exception of a few known paternally methylated germline differentially methylated regions (DMRs) associated with known imprinted domains, we demonstrate that sperm-derived methylation is reprogrammed by the blastocyst stage of development. In contrast a large number of oocyte-derived methylation differences survive to the blastocyst stage and uniquely persist as transiently methylated DMRs only in the placenta. Furthermore, we demonstrate that this phenomenon is exclusive to primates, since no placenta-specific maternal methylation was observed in mouse. Utilizing single cell RNA-seq datasets from human preimplantation embryos we show that following embryonic genome activation the maternally methylated transient DMRs can orchestrate imprinted expression. However despite showing widespread imprinted expression of genes in placenta, allele-specific transcriptional profiling revealed that not all placenta-specific DMRs coordinate imprinted expression and that this maternal methylation may be absent in a minority of samples, suggestive of polymorphic imprinted methylation
