The Current Landscape of Prostitution and Sex Work in England and Wales

This paper presents a comprehensive typology of the sex industry based on primary data collected between 2018 and 2019 for a UK Home Office-funded study. Typologies of the contemporary sex industry in England and Wales have tended to be limited to particular sectors or have been developed from a specific disciplinary perspective or theme (e.g. sexual health programming, income). Situated in the context of international sex industry typologies, this paper seeks to address this gap. Data was derived from an online survey, questionnaires and consultations with stakeholders including individuals currently or formerly involved in selling sex, service providers/NGOs, police, local authority representatives and others. The data was supplemented with insights from a systematic literature search. This work aims to assist with programme and policy planning in the UK context. Our methods can assist in developing typologies in other contexts

‘On the outside I’m smiling but inside I’m crying’: communication successes and challenges for undergraduate academic writing

Student difficulties with the transition to writing in higher education are well documented whether from a ‘study skills’, an ‘academic socialisation’ or an ‘academic literacies’ perspective. In order to more closely examine the challenges faced by students from widening participation backgrounds and diverse routes into undergraduate study, this project focuses on first-year undergraduate experiences of developing academic literacies on an Education Studies programme at one university in England. It highlights the impact of different support and guidance within and beyond their degree programme where attempts to embed academic literacy development are part of subject modules. The paper reports the findings generated using a mixed methods interpretive approach. Questionnaires were collected at the beginning (n = 48) and end of the students’ first year (n = 44), and interviews and visual data collection methods (n =19) were used at the mid-point of the academic year. Key findings highlight students’ expectations of achievement on entry to university and the influence of the emotional journey of students as they begin to make progress as academic writers. Identifying, selecting and applying academic reading were an enduring concern whilst some students struggled with the digital literacy implicit in undergraduate work. Importantly, some strategies developed to support student transition to academic writing in higher education may have unintended consequences as they progress through the first year

Global analysis of protein-RNA interactions in SARS-CoV-2 infected cells reveals key regulators of infection

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes COVID-19. SARS-CoV-2 relies on cellular RNA-binding proteins (RBPs) to replicate and spread, although which RBPs control its life cycle remains largely unknown. Here, we employ a multi-omic approach to identify systematically and comprehensively the cellular and viral RBPs that are involved in SARS-CoV-2 infection. We reveal that SARS-CoV-2 infection profoundly remodels the cellular RNA-bound proteome, which includes wide-ranging effects on RNA metabolic pathways, non-canonical RBPs and antiviral factors. Moreover, we apply a new method to identify the proteins that directly interact with viral RNA, uncovering dozens of cellular RBPs and six viral proteins. Amongst them, several components of the tRNA ligase complex, which we show regulate SARS-CoV-2 infection. Furthermore, we discover that available drugs targeting host RBPs that interact with SARS-CoV-2 RNA inhibit infection. Collectively, our results uncover a new universe of host-virus interactions with potential for new antiviral therapies against COVID-19

Effect of collaborative care vs usual care on depressive symptoms among older adults with sub-threshold depression : the CASPER randomized clinical trial

In the CASPER randomized trial of 705 participants age 65 and older with sub-threshold depression, those randomized to a collaborative care intervention had lower depression scores, measured by the Patient Health 9-item questionnaire at 4 month follow-up, compared to usual care

Addressing Accuracy and Precision Issues in iTRAQ Quantitation*

iTRAQ (isobaric tags for relative or absolute quantitation) is a mass spectrometry technology that allows quantitative comparison of protein abundance by measuring peak intensities of reporter ions released from iTRAQ-tagged peptides by fragmentation during MS/MS. However, current data analysis techniques for iTRAQ struggle to report reliable relative protein abundance estimates and suffer with problems of precision and accuracy. The precision of the data is affected by variance heterogeneity: low signal data have higher relative variability; however, low abundance peptides dominate data sets. Accuracy is compromised as ratios are compressed toward 1, leading to underestimation of the ratio. This study investigated both issues and proposed a methodology that combines the peptide measurements to give a robust protein estimate even when the data for the protein are sparse or at low intensity. Our data indicated that ratio compression arises from contamination during precursor ion selection, which occurs at a consistent proportion within an experiment and thus results in a linear relationship between expected and observed ratios. We proposed that a correction factor can be calculated from spiked proteins at known ratios. Then we demonstrated that variance heterogeneity is present in iTRAQ data sets irrespective of the analytical packages, LC-MS/MS instrumentation, and iTRAQ labeling kit (4-plex or 8-plex) used. We proposed using an additive-multiplicative error model for peak intensities in MS/MS quantitation and demonstrated that a variance-stabilizing normalization is able to address the error structure and stabilize the variance across the entire intensity range. The resulting uniform variance structure simplifies the downstream analysis. Heterogeneity of variance consistent with an additive-multiplicative model has been reported in other MS-based quantitation including fields outside of proteomics; consequently the variance-stabilizing normalization methodology has the potential to increase the capabilities of MS in quantitation across diverse areas of biology and chemistry

Microduplication and Triplication of 22q11.2: A Highly Variable Syndrome

22q11.2 microduplications of a 3-Mb region surrounded by low-copy repeats should be, theoretically, as frequent as the deletions of this region; however, few microduplications have been reported. We show that the phenotype of these patients with microduplications is extremely diverse, ranging from normal to behavioral abnormalities to multiple defects, only some of which are reminiscent of the 22q11.2 deletion syndrome. This diversity will make ascertainment difficult and will necessitate a rapid-screening method. We demonstrate the utility of four different screening methods. Although all the screening techniques give unique information, the efficiency of real-time polymerase chain reaction allowed the discovery of two 22q11.2 microduplications in a series of 275 females who tested negative for fragile X syndrome, thus widening the phenotypic diversity. Ascertainment of the fragile X–negative cohort was twice that of the cohort screened for the 22q11.2 deletion. We also report the first patient with a 22q11.2 triplication and show that this patient's mother carries a 22q11.2 microduplication. We strongly recommend that other family members of patients with 22q11.2 microduplications also be tested, since we found several phenotypically normal parents who were carriers of the chromosomal abnormality

Circadian orchestration of the hepatic proteome

SummaryCircadian rhythms are essential to health. Their disruption is associated with metabolic diseases in experimental animals and man [1–3]. Local metabolic rhythms represent an output of tissue-based circadian clocks [4]. Attempts to define how local metabolism is temporally coordinated have focused on gene expression by defining extensive and divergent “circadian transcriptomes” involving 5%–10% of genes assayed [5–8]. These analyses are inevitably incomplete, not least because metabolic coordination depends ultimately upon temporal regulation of proteins [9, 10]. We therefore conducted a systematic analysis of a mammalian “circadian proteome.” Our analysis revealed that up to 20% of soluble proteins assayed in mouse liver are subject to circadian control. Many of these circadian proteins are novel and cluster into discrete phase groups so that the liver's enzymatic profile contrasts dramatically between day and night. Unexpectedly, almost half of the cycling proteins lack a corresponding cycling transcript, as determined by quantitative PCR, microarray, or both and revealing for the first time the extent of posttranscriptional mechanisms as circadian control points. The circadian proteome includes rate-limiting factors in vital pathways, including urea formation and sugar metabolism. These findings provide a new perspective on the extensive contribution of circadian programming to hepatic physiology
