Seeing behind the curtain: Reverse Mentoring within the Higher Education landscape

The following article presents the findings of a Reverse Mentoring evaluation project conducted at a modern university in northwest England, which has a high proportion of students from non-traditional educational backgrounds. Using a reverse mentoring framework, the traditional mentor–mentee relationship was flipped with students serving as senior partners and their tutors as junior partners. The purpose of this study was to investigate how staff–student relations could be strengthened by gaining a better understanding of one another’s perspectives. The concept of institutional habitus provided a theoretical framework within which to examine disparities in mentor–mentee cultural understanding. Using a mixed approach to data collection, composite narratives were constructed. They revealed subtle cultural mismatches between the positions of mentor and mentee. The study speculates that by gaining a better understanding and appreciation of students’ habitus, more inclusive teaching practises can be developed to ensure the inclusion of all students

Health literacy and the framing of health messages in the gay community

An aim of current UK health policy is to ‘fully engage’ not only sick but also well people in pursuit of health (Wanless 2004). In this policy discourse, it is assumed that ‘health literacy’ is one of the vehicles for achieving that full engagement: namely, individuals must understand the best information about how to pursue health, not only have access to it. The present project focuses on three related issues: (1) how health information is ‘framed’, and (2) how that information is understood, evaluated and acted on by those who receive it and (3) in light of the results, what dimensions ‘health literacy’ must have if changes in health-related behaviour are to ensue. Our focus is men’s health. It is widely recognised that men are less likely to engage with their own health than women with theirs. We choose gay men as a critical case. We single out varieties of gay men in Manchester and specifically the health issues they share with other men

Getting students out there; using community partnerships to engage students

Purpose The purpose of the paper is to discuss the “Q-Step in the Community” programme, part of the Q-Step Centre based in the Sociology Department at Manchester Metropolitan University, designed to help address the skills gap in quantitative methods (QM) that is evident across parts of the UK higher-education sector. “Q-Step in the Community” is a data-driven work-based learning programme that works in partnership with local organisations to provide placement opportunities for final year undergraduates and postgraduates. Students conduct a quantitative research project, which is typically identified by the placement provider. Design/methodology/approach The authors use quantitative and qualitative feedback from students and placement providers, along with our own reflections on the process to evaluate the placement programme. Data were collected through a focus group and email interviews with placement providers, along with a questionnaire, which was distributed to “Q-Step in the Community” alumni. Findings Data-driven work-based learning opportunities allow students to develop and demonstrate their quantitative skills and support networking opportunities whilst also developing valuable soft-skills experience of the workplace that develops their career-readiness. In addition, those opportunities provide valuable research for placement providers, which support their sustainability and enhance their service delivery. Research limitations/implications The research focusses solely on one programme at one university offering quantitative data driven work-based learning opportunities at undergraduate and post-graduate level. It is not possible to make valid comparisons between those who do a placement with those who do not. Originality/value Views of key stakeholders in the process have been sought for this research, which can be useful to consider for others considering developing similar programmes for their students

Is Precarious Employment Low Income Employment? The Changing Labour Market in Southern Ontario

This paper examines the association between income and precarious employment, how this association is changing and how it is shaped by gender and race. It explores how precarious employment has spread to even middle income occupations and what this implies for our understanding of contemporary labour markets and employment relationship norms. The findings indicate a need to refine our views of who is in precarious employment and a need to re-evaluate the nature of the Standard Employment Relationship, which we would argue is not only becoming less prevalent, but also transitioning into something that is less secure

Nrf2 is overexpressed in pancreatic cancer: implications for cell proliferation and therapy

<p>Abstract</p> <p>Background</p> <p>Nrf2 is a key transcriptional regulator of a battery of genes that facilitate phase II/III drug metabolism and defence against oxidative stress. Nrf2 is largely regulated by Keap1, which directs Nrf2 for proteasomal degradation. The Nrf2/Keap1 system is dysregulated in lung, head and neck, and breast cancers and this affects cellular proliferation and response to therapy. Here, we have investigated the integrity of the Nrf2/Keap1 system in pancreatic cancer.</p> <p>Results</p> <p>Keap1, Nrf2 and the Nrf2 target genes AKR1c1 and GCLC were detected in a panel of five pancreatic cancer cell lines. Mutation analysis of <it>NRF2 </it>exon 2 and <it>KEAP1 </it>exons 2-6 in these cell lines identified no mutations in <it>NRF2 </it>and only synonomous mutations in <it>KEAP1</it>. RNAi depletion of Nrf2 caused a decrease in the proliferation of Suit-2, MiaPaca-2 and FAMPAC cells and enhanced sensitivity to gemcitabine (Suit-2), 5-flurouracil (FAMPAC), cisplatin (Suit-2 and FAMPAC) and gamma radiation (Suit-2). The expression of Nrf2 and Keap1 was also analysed in pancreatic ductal adenocarcinomas (n = 66 and 57, respectively) and matching normal benign epithelium (n = 21 cases). Whilst no significant correlation was seen between the expression levels of Keap1 and Nrf2 in the tumors, interestingly, Nrf2 staining was significantly greater in the cytoplasm of tumors compared to benign ducts (P < 0.001).</p> <p>Conclusions</p> <p>Expression of Nrf2 is up-regulated in pancreatic cancer cell lines and ductal adenocarcinomas. This may reflect a greater intrinsic capacity of these cells to respond to stress signals and resist chemotherapeutic interventions. Nrf2 also appears to support proliferation in certain pancreatic adenocarinomas. Therefore, strategies to pharmacologically manipulate the levels and/or activity of Nrf2 may have the potential to reduce pancreatic tumor growth, and increase sensitivity to therapeutics.</p

Green tea polyphenol treatment is chondroprotective, anti-inflammatory and palliative in a mouse posttraumatic osteoarthritis model

Introduction Epigallocatechin 3-gallate (EGCG), a polyphenol present in green tea, was shown to exert chondroprotective effects in vitro. In this study, we used a posttraumatic osteoarthritis (OA) mouse model to test whether EGCG could slow the progression of OA and relieve OA-associated pain. Methods C57BL/6 mice were subjected to surgical destabilization of the medial meniscus (DMM) or sham surgery. EGCG (25 mg/kg) or vehicle control was administered daily for 4 or 8 weeks by intraperitoneal injection starting on the day of surgery. OA severity was evaluated using Safranin O staining and Osteoarthritis Research Society International (OARSI) scores, as well as by immunohistochemical analysis to detect cleaved aggrecan and type II collagen and expression of proteolytic enzymes matrix metalloproteinase 13 (MMP-13) and A disintegrin and metalloproteinase with thrombospondin motifs 5 (ADAMTS5). Real-time PCR was performed to characterize the expression of genes critical for articular cartilage homeostasis. During the course of the experiments, tactile sensitivity testing (von Frey test) and open-field assays were used to evaluate pain behaviors associated with OA, and expression of pain expression markers and inflammatory cytokines in the dorsal root ganglion (DRG) was determined by real-time PCR. Results Four and eight weeks after DMM surgery, the cartilage in EGCG-treated mice exhibited less Safranin O loss and cartilage erosion, as well as lower OARSI scores compared to vehicle-treated controls, which was associated with reduced staining for aggrecan and type II collagen cleavage epitopes, and reduced staining for MMP-13 and ADAMTS5 in the articular cartilage. Articular cartilage in the EGCG-treated mice also exhibited reduced levels of Mmp1, Mmp3, Mmp8, Mmp13,Adamts5, interleukin 1 beta (Il1b) and tumor necrosis factor alpha (Tnfa) mRNA and elevated gene expression of the MMP regulator Cbp/p300 interacting transactivator 2 (Cited2). Compared to vehicle controls, mice treated with EGCG exhibited reduced OA-associated pain, as indicated by higher locomotor behavior (that is, distance traveled). Moreover, expression of the chemokine receptor Ccr2 and proinflammatory cytokines Il1b and Tnfa in the DRG were significantly reduced to levels similar to those of sham-operated animals. Conclusions This study provides the first evidence in an OA animal model that EGCG significantly slows OA disease progression and exerts a palliative effect.

Cross-sectional study evaluating the impact of SARS-CoV-2 variants on Long COVID outcomes in UK hospital survivors

OBJECTIVES: COVID-19 studies report on hospital admission outcomes across SARS-CoV-2 waves of infection but knowledge of the impact of SARS-CoV-2 variants on the development of Long COVID in hospital survivors is limited. We sought to investigate Long COVID outcomes, aiming to compare outcomes in adult hospitalised survivors with known variants of concern during our first and second UK COVID-19 waves, prior to widespread vaccination. DESIGN: Prospective observational cross-sectional study. SETTING: Secondary care tertiary hospital in the UK. PARTICIPANTS: This study investigated Long COVID in 673 adults with laboratory-positive SARS-CoV-2 infection or clinically suspected COVID-19, 6 weeks after hospital discharge. We compared adults with wave 1 (wildtype variant, admitted from February to April 2020) and wave 2 patients (confirmed Alpha variant on viral sequencing (B.1.1.7), admitted from December 2020 to February 2021). OUTCOME MEASURES: Associations of Long COVID presence (one or more of 14 symptoms) and total number of Long COVID symptoms with SARS-CoV-2 variant were analysed using multiple logistic and Poisson regression, respectively. RESULTS: 322/400 (wave 1) and 248/273 (wave 2) patients completed follow-up. Predictors of increased total number of Long COVID symptoms included: pre-existing lung disease (adjusted count ratio (aCR)=1.26, 95% CI 1.07, 1.48) and more COVID-19 admission symptoms (aCR=1.07, 95% CI 1.02, 1.12). Weaker associations included increased length of inpatient stay (aCR=1.02, 95% CI 1.00, 1.03) and later review after discharge (aCR=1.00, 95% CI 1.00, 1.01). SARS-CoV-2 variant was not associated with Long COVID presence (OR=0.99, 95% CI 0.24, 4.20) or total number of symptoms (aCR=1.09, 95% CI 0.82, 1.44). CONCLUSIONS: Patients with chronic lung disease or greater COVID-19 admission symptoms have higher Long COVID risk. SARS-CoV-2 variant was not predictive of Long COVID though in wave 2 we identified fewer admission symptoms, improved clinical trajectory and outcomes. Addressing modifiable factors such as length of stay and timepoint of clinical review following discharge may enable clinicians to move from Long COVID risk stratification towards improving its outcome

Innovative organotypic in vitro models for safety assessment: aligning with regulatory requirements and understanding models of the heart, skin, and liver as paradigms

The development of improved, innovative models for the detection of toxicity of drugs, chemicals, or chemicals in cosmetics is crucial to efficiently bring new products safely to market in a cost-effective and timely manner. In addition, improvement in models to detect toxicity may reduce the incidence of unexpected post-marketing toxicity and reduce or eliminate the need for animal testing. The safety of novel products of the pharmaceutical, chemical, or cosmetics industry must be assured; therefore, toxicological properties need to be assessed. Accepted methods for gathering the information required by law for approval of substances are often animal methods. To reduce, refine, and replace animal testing, innovative organotypic in vitro models have emerged. Such models appear at different levels of complexity ranging from simpler, self-organized three-dimensional (3D) cell cultures up to more advanced scaffold-based co-cultures consisting of multiple cell types. This review provides an overview of recent developments in the field of toxicity testing with in vitro models for three major organ types: heart, skin, and liver. This review also examines regulatory aspects of such models in Europe and the UK, and summarizes best practices to facilitate the acceptance and appropriate use of advanced in vitro models
