The Rising Tide Of Revisional Surgery: Tracking Changes In Index Cases Among Bariatric-Accredited Fellowships, Holger K Eltzschig Jan 2023

The Rising Tide Of Revisional Surgery: Tracking Changes In Index Cases Among Bariatric-Accredited Fellowships, Holger K Eltzschig

Faculty, Staff and Student Publications

Pancreatic ductal adenocarcinoma (PDAC) is characterized by a dense desmoplastic stroma that impedes drug delivery, reduces parenchymal blood flow, and suppresses the anti-tumor immune response. The extracellular matrix and abundance of stromal cells result in severe hypoxia within the tumor microenvironment (TME), and emerging publications evaluating PDAC tumorigenesis have shown the adenosine signaling pathway promotes an immunosuppressive TME and contributes to the overall low survival rate. Hypoxia increases many elements of the adenosine signaling pathway, resulting in higher adenosine levels in the TME, further contributing to immune suppression. Extracellular adenosine signals through 4 adenosine receptors (Adora1, Adora2a, Adora2b, Adora3). Of …

CVR is particularly prevalent in secondary progressive MS (SPMS) and can be quantified through validated composite CVR scores. The aim was to examine the cross‐sectional relationships between excess modifiable CVR, whole and regional brain atrophy on magnetic resonance imaging, and disability in patients with SPMS. Methods. Participants had SPMS, and data were collected at enrolment into the MS‐STAT2 trial. Composite CVR scores were calculated using the QRISK3 software. Prematurely achieved CVR due to modifiable risk factors was expressed as QRISK3 premature CVR, …


An Isotopic Analysis Of Carbon Dynamics In Sphagnum Peat, Jasper Michael Newman Jan 2023

An Isotopic Analysis Of Carbon Dynamics In Sphagnum Peat, Jasper Michael Newman

School of Geography, Earth and Environmental Sciences Theses

Methane and carbon dioxide produced in peatlands can be held temporarily in dissolved surface waters and accessible to aquatic plants. The primary peat building plant in northern peatlands, Sphagnum moss, grows in these dissolved carbon rich waters. Understanding Sphagnum carbon cycles is key for radiocarbon dating, peatland restoration, and modelling of methane release from warming peatlands globally. This combined surface and multi‐proxy palaeoenvironmental study challenges common assumptions about the dissolved gas cycling in this semi‐aquatic environment. The Sphagnum associated methanotrophic communities within the water filled hyaline cells have commonly been linked to unusual 13C‐depleted measurements of Sphagnum carbon isotope ratios. …

School of Engineering, Computing and Mathematics

Human behaviors and attitudes play a significant role in cybersecurity. However, studies to quantify the impact of such behaviors and attitudes are scarce, and they are not always considered when developing mitigation strategies. To compensate for this, we have looked into a large sample of employees with different levels of expertise and backgrounds across a variety of industrial sectors and organizations. We have found that age and job role constitute the main human factors associated with social media cybersecurity risks. We can confirm that the youngest employees are the most risk prone within an organization, and the employees working in …

Major planktonic lifeforms such as diatoms, dinoflagellates, meroplankton and holoplankton have recently shown significant and alarming changes in abundance - mainly downwards trends - around the northwest European shelf. This has major implications for food web connections and for ecosystem services including seafood provision and carbon storage. We have quantified these changes in abundance for 2006–2019/20 using a Plankton Index (PI) and show that the scale of spatial aggregation is critical to the ability of the PI to detect change, understand causal mechanisms, and provide advice to policymakers. We derived PI statistics in the Celtic and North Seas from data …

Investigating A Motivation Model For Gamified E-Learning: A Self-Determination Approach, A Sen, J Lean, J Kelland, J Moizer Jan 2023

Investigating A Motivation Model For Gamified E-Learning: A Self-Determination Approach, A Sen, J Lean, J Kelland, J Moizer

Plymouth Business School

There has been a recent increase in educational interest in gamification over the past 5 years [1, 2]. A central tenet of the increase in its popularity may stem from its motivational power in educational settings [3, 4]. However, prior research on gamification has not sufficiently investigated the mechanisms by which the phenomenon induces its motivational effects. A crucial question to consider is how the motivational theories that underpin gamification really work. Consequently, the current study looks at how game elements map into the notion of self-determination to explore the relationship between intrinsic motivation and gamification in the context of …


Paternal Supervisor Gatekeeping: How Supervising Fathers Hinder Other Fathers At Work In Their Uptake Of Flexible Work Arrangements, Sophie Hennekam, Jasmine Kelland, Jean Pierre Dumazert Jan 2023

Paternal Supervisor Gatekeeping: How Supervising Fathers Hinder Other Fathers At Work In Their Uptake Of Flexible Work Arrangements, Sophie Hennekam, Jasmine Kelland, Jean Pierre Dumazert

Plymouth Business School

This study explores the role that supervisors play in the low uptake of Flexible Work Arrangements (FWA) among fathers in France. We draw on 28 interviews with fathers who had requested access to FWA and reported on the reaction of their supervisors. These supervisors were all fathers themselves and had previously benefitted from such arrangements themselves, but did not grant such policies to other fathers. To understand these unexpected findings, we conducted an additional 16 interviews with supervising fathers in organizations who had previously enjoyed similar FWA. The findings show that supervising fathers can act as barriers to other fathers …

Spatial Robustness: Double-Design And The Democratization Of Space, An Exploration Of Designing For Multiple Uses, Michael Cassidy

School of Art, Design and Architecture Theses

Spatial Robustness: Double-design And The Democratization Of Space, An Exploration Of Designing For Multiple Uses by Michael Warren Arkinstall Cassidy Differing attitudes to the expected life and value of architecture characterize the sustainability debate, yet space itself is rarely mentioned. The buildings for which architecture is responsible comprise both space and materials. While it is taken for granted that some existing buildings can be reused productively, this cultural phenomenon has not influenced the design of the new stock. While content to revere old buildings, the qualities that make them valued have not influenced design principles for new projects. Should new …


Shanshuihua: ‘Mountain-Water-Painting’ For An Ecological Age, Lei Liu Jan 2023

Shanshuihua: ‘Mountain-Water-Painting’ For An Ecological Age, Lei Liu

School of Art, Design and Architecture Theses

This practice-led research project appraises the tradition of shanshuihua, or ‘mountain-water painting’, within broader traditions of Chinese ink painting, or shuimohua, and, through links with ancient Chinese philosophies, considers its continuing relevance to contemporary painting, and modern ecological themes, both in China and beyond. The research initially assesses historical connections between ink painting and the fundamental philosophies of Chinese history and culture, namely Confucianism, Taoism and Buddhism, and maps certain connections to the development of shanshuihua. Through a series of interviews with contemporary Chinese artists, the project investigates whether the influence of these philosophic traditions have a continuing significance to …


Hippo Signaling: Advances In Potential Therapeutic Targets For Sinoatrial Node Disorders Jan 2023

Hippo Signaling: Advances In Potential Therapeutic Targets For Sinoatrial Node Disorders

Faculty, Staff and Student Publications

The cardiac conduction system (CCS) propagates electrical impulses, generates cardiac contractions, and ultimately ensures regular heartbeats. Disruptions within the CCS lead to cardiac arrhythmias, which are known to be the leading cause of cardiac-related mortalities in humans. The sinoatrial node (SAN) is a key component of the CCS and functions as the natural cardiac pacemaker to initiate normal cardiac impulse and conduction. The SAN is characterized by significant heterogeneity and contains various cell types, including pacemaker cells that spontaneously generate action potentials to maintain a constant beating rhythm. The fundamental Hippo signaling pathway plays a key role in heart development …


Exaptation And Evolutionary Adaptation In Nociceptor Mechanisms Driving Persistent Pain Jan 2023

Exaptation And Evolutionary Adaptation In Nociceptor Mechanisms Driving Persistent Pain

Faculty, Staff and Student Publications

Background: Several evolutionary explanations have been proposed for why chronic pain is a major clinical problem. One is that some mechanisms important for driving chronic pain, while maladaptive for modern humans, were adaptive because they enhanced survival. Evidence is reviewed for persistent nociceptor hyperactivity (PNH), known to promote chronic pain in rodents and humans, being an evolutionarily adaptive response to significant bodily injury, and primitive molecular mechanisms related to cellular injury and stress being exapted (co-opted or repurposed) to drive PNH and consequent pain.

Summary: PNH in a snail (Aplysia californica), squid (Doryteuthis pealeii), fruit fly (Drosophila melanogaster), mice, rats, …


Unveiling The Prognostic Implications Of Rplp1 Upregulation In Osteosarcoma, Ruiying Zhao Jan 2023

Unveiling The Prognostic Implications Of Rplp1 Upregulation In Osteosarcoma, Ruiying Zhao

Faculty, Staff and Student Publications

Osteosarcoma, a malignant bone tumor characterized by a high rate of metastasis and poor survival, presents a critical need for identifying novel biomarkers associated with metastasis. In this study, we conducted an extensive analysis utilizing transcriptional and clinical data sourced from databases such as GEO, TCGA, CCLE, R2, and Xena. And we discovered that Ribosomal protein LP1 (RPLP1) ranked among the top upregulated genes in relation to osteosarcoma metastasis. Notably, RPLP1 exhibited significant expression in both osteosarcoma cell lines and patient samples. Moreover, multiple osteosarcoma studies revealed a strong correlation between RPLP1 overexpression and worse metastasis-free survival as well as …


Frequentist Model Averaging For Analysis Of Dose-Response In Epidemiologic Studies With Complex Exposure Uncertainty Jan 2023

Frequentist Model Averaging For Analysis Of Dose-Response In Epidemiologic Studies With Complex Exposure Uncertainty

Faculty, Staff and Student Publications

In epidemiologic studies, association estimates of an exposure with disease outcomes are often biased when the uncertainties of exposure are ignored. Consequently, corresponding confidence intervals (CIs) will not have correct coverage. This issue is particularly problematic when exposures must be reconstructed from physical measurements, for example, for environmental or occupational radiation doses that were received by a study population for which radiation doses cannot be measured directly. To incorporate complex uncertainties in reconstructed exposures, the two-dimensional Monte Carlo (2DMC) dose estimation method has been proposed and used in various dose reconstruction efforts. The 2DMC method generates multiple exposure realizations from …

In this editorial we introduce a new non-profit open access journal, Imaging Neuroscience. In April 2023, editors of the journals NeuroImage and NeuroImage:Reports resigned, and a month later launched Imaging Neuroscience. NeuroImage had long been the leading journal in the field of neuroimaging. While the move to fully open access in 2020 represented a positive step toward modern academic practices, the publication fee was set to a level that the editors found unethical and unsustainable. The publisher of NeuroImage, Elsevier, was unwilling to reduce the fee after much discussion. This led us to launch Imaging Neuroscience with …
