Considering connections between Hollywood and biodiversity conservation

This is the author accepted manuscript. The final version is available from the publisher via the DOI in this record.Cinema offers a substantial opportunity to share messages with a wide audience. Given its global range and potentially high impact, there is an urgent need for research that evaluates the effects of this form of visual media on conservation outcomes. Cinema can influence the awareness and behaviours of non-specialist audiences, and could therefore play an important positive and/or negative role in biodiversity conservation through behavioural change and social pressure on key stakeholders and policy makers. Limited awareness about the potential benefits and limitations of cinema for conservation, as well as a lack of evidence about impacts, currently hinder our ability to learn from previous and ongoing initiatives, and to engage productively with the movie industry. We discuss the key opportunities and risks that arise from cinematic representations of conservation issues and species of concern, making use of examples and case studies where they are available. We additionally provide a framework that enables conservationists to better understand and engage with the film industry, highlighting how this can facilitate engagement with the movie industry, harness its potential, and improve work to mitigate any negative consequences. A robust evidence base is key for evaluating and planning these engagements, and for informing related policy and management decisions. This article is protected by copyright.

This is the final version. Available on open access from Wiley via the DOI in this recordData availability statement: Raw data and R code can be accessed via Zenodo at the following URL: https://doi.org/10.5281/zenodo.4899586 (Crowley et al., 2021). Qualitative coding structure and details are available on request.Playing video games is often perceived as the antithesis of engaging with, and learning about, the natural world. Nevertheless, there is growing recognition that digital media is now a central part of many people's lives. This has led to increased efforts to harness the power and popularity of digital games for both ecological education and conservation advocacy. Games designed for educational purposes may be perceived as too niche, or have insufficient resources, to reach wider audiences. In contrast, big budget video games reach many millions of players, but are generally designed for entertainment rather than education. Red Dead Redemption 2 (RDR2), a Western-themed action-adventure game, is one such product. Nevertheless, due to its detailed, open-world simulation of late 19th century North American ecosystems, it provides opportunities for players to learn about real-world wildlife. We surveyed self-described gamers who both had, and had not, played RDR2. Participants undertook a wildlife identification quiz focusing on 15 species depicted in the game. We also asked participants about their self-reported learning and experiences of playing RDR2. We found that participants who had played RDR2 correctly identified more species in the quiz, with this improvement enhanced by having completed the game's main storyline, played more recently or played online in a ‘Naturalist’ role. The difference in performance was greatest for ungulate and fish species which have high in-game utility value. In addition to species identification, participants reported learning about animal behaviours and interspecies interactions. Their most memorable experiences were associated with RDR2's immersive environment and ability to provoke emotional responses. We conclude that big-budget video games can have educational as well as entertainment value and should be taken seriously by educators, ecologists and conservationists as a communicative force

What's in a Face? Mentalizing in Borderline Personality Disorder Based on Dynamically Changing Facial Expressions

The mentalization-based approach to borderline personality disorder (BPD) argues that impairments in mentalizing are a key feature of BPD. Most previous research in this area has concentrated on potential impairments in facial emotion recognition in BPD patients. However, these studies have yielded inconsistent results, which may be attributable to methodological differences. This study aimed to address several limitations of previous studies by investigating different parameters involved in emotion recognition in BPD patients using a novel, 2-step dynamically changing facial expression paradigm, taking into account the possible influence of mood, psychotropic medication, and trauma exposure. Twenty-two BPD patients and 22 matched normal controls completed this paradigm. Parameters assessed were accuracy of emotion recognition, reaction time (RT), and level of confidence, both for first and full response and for correct and incorrect responses. Results showed (a) that BPD patients were as accurate in their first, but less accurate in their full emotion recognition than normal controls, (b) a trend for BPD patients to respond more slowly than normal controls, and (c) no significant difference in overall level of confidence between BPD patients and normal controls. Mood and psychotropic medication did not influence these results. Exposure to trauma in BPD patients, however, was negatively related to accuracy at full expression. Although further research is needed, results suggest no general emotion-recognition deficit in BPD patients using a dynamic changing facial recognition paradigm, except for a subgroup of BPD patients with marked trauma who become less accurate when they have to rely more on controlled, reflective processes

Reward-Related Neural Activity and Adolescent Antisocial Behavior in a Community Sample

Behavioral research has found evidence supporting reward dominance in adolescence with externalizing disorders, but findings from neuroimaging studies have been largely heterogeneous. We examined the Feedback-Related Negativity (FRN) and P3b in relation to self-reported externalizing behavior among 78 adolescents (11-18 yrs) during a monetary gambling task with concurrent high-density electroencephalogram. As expected, the P3b and the FRN demonstrated greater evoked activity to reward and punishment, respectively. Further, high externalizing behavior was associated with greater P3b difference and reduced FRN difference in response to reward and punishment, suggesting that externalizing behaviors may be associated with both reward dominance and reduced feedback-monitoring

The effect of nitric oxide on the pressure of the acutely obstructed ureter

Acute ureteral obstruction leads to changes in pressure inside the ureter, interrupting ureter function. The aim of our study is to explore the relationship between nitric oxide (NO) concentration and pressure in the ureter and to observe the effects of nitric oxide on the revival of renal function. We created the animal models by embedding balloons in the lower ureters of anesthetized dogs and expanding them to simulate acute ureteral obstruction. First, the test animals were pre-treated intravenously with different doses of L-NAME (non-selective nitric oxide synthase inhibitor) to inhibit nitric oxide synthase (NOS), and 10 min later, each subject was administered an intravenous dose of isoproterenol (10 μg/kg). We measured ureter pressure (UP), total and peak concentrations of NO (using an NO monitor, model inNO-T) in ureteral urine, and the volume of the urine (UFV) leaking from the balloon edge. After a certain amount of time had elapsed, it became clear that the dose of L-NAME was inversely related to the total and peak concentrations of NO, the rate of change in UP, and the volume of urine produced. We conclude that L-NAME prevents the NOS from inhibiting the release of NO, then inhibits the effect of isoproterenol reducing the pressure of the acute obstructive ureter. Inversely, we think that NO can reduce the pressure of the acute obstructive ureter and make the obstructive ureter recanalization. And when more the concentration of nitric oxide, the more the pressure will be reduced, and more urine will be collected

Tissue-engineered tracheal replacement in a child: a 4-year follow-up study

In 2010, a tissue-engineered trachea was transplanted into a 10-year-old child using a decellularized deceased donor trachea repopulated with the recipient's respiratory epithelium and mesenchymal stromal cells. We report the child's clinical progress, tracheal epithelialization and costs over the 4 years. A chronology of events was derived from clinical notes and costs determined using reference costs per procedure. Serial tracheoscopy images, lung function tests and anti-HLA blood samples were compared. Epithelial morphology and T cell, Ki67 and cleaved caspase 3 activity were examined. Computational fluid dynamic simulations determined flow, velocity and airway pressure drops. After the first year following transplantation, the number of interventions fell and the child is currently clinically well and continues in education. Endoscopy demonstrated a complete mucosal lining at 15 months, despite retention of a stent. Histocytology indicates a differentiated respiratory layer and no abnormal immune activity. Computational fluid dynamic analysis demonstrated increased velocity and pressure drops around a distal tracheal narrowing. Cross-sectional area analysis showed restriction of growth within an area of in-stent stenosis. This report demonstrates the long-term viability of a decellularized tissue-engineered trachea within a child. Further research is needed to develop bioengineered pediatric tracheal replacements with lower morbidity, better biomechanics and lower costs

Tracheal Replacement Therapy with a Stem Cell-Seeded Graft: Lessons from Compassionate Use Application of a GMP-Compliant Tissue-Engineered Medicine

Tracheal replacement for the treatment of end-stage airway disease remains an elusive goal. The use of tissue-engineered tracheae in compassionate use cases suggests that such an approach is a viable option. Here, a stem cell-seeded, decellularized tissue-engineered tracheal graft was used on a compassionate basis for a girl with critical tracheal stenosis after conventional reconstructive techniques failed. The graft represents the first cell-seeded tracheal graft manufactured to full good manufacturing practice (GMP) standards. We report important preclinical and clinical data from the case, which ended in the death of the recipient. Early results were encouraging, but an acute event, hypothesized to be an intrathoracic bleed, caused sudden airway obstruction 3 weeks post-transplantation, resulting in her death. We detail the clinical events and identify areas of priority to improve future grafts. In particular, we advocate the use of stents during the first few months post-implantation. The negative outcome of this case highlights the inherent difficulties in clinical translation where preclinical in vivo models cannot replicate complex clinical scenarios that are encountered. The practical difficulties in delivering GMP grafts underscore the need to refine protocols for phase I clinical trials

Quail Genomics: a knowledgebase for Northern bobwhite

<p>Abstract</p> <p>Background</p> <p>The Quail Genomics knowledgebase (<url>http://www.quailgenomics.info</url>) has been initiated to share and develop functional genomic data for Northern bobwhite (<it>Colinus virginianus</it>). This web-based platform has been designed to allow researchers to perform analysis and curate genomic information for this non-model species that has little supporting information in GenBank.</p> <p>Description</p> <p>A multi-tissue, normalized cDNA library generated for Northern bobwhite was sequenced using 454 Life Sciences next generation sequencing. The Quail Genomics knowledgebase represents the 478,142 raw ESTs generated from the sequencing effort in addition to assembled nucleotide and protein sequences including 21,980 unigenes annotated with meta-data. A normalized MySQL relational database was established to provide comprehensive search parameters where meta-data can be retrieved using functional and structural information annotation such as gene name, pathways and protein domain. Additionally, blast hit cutoff levels and microarray expression data are available for batch searches. A Gene Ontology (GO) browser from Amigo is locally hosted providing 8,825 unigenes that are putative orthologs to chicken genes. In an effort to address over abundance of Northern bobwhite unigenes (71,384) caused by non-overlapping contigs and singletons, we have built a pipeline that generates scaffolds/supercontigs by aligning partial sequence fragments against the indexed protein database of chicken to build longer sequences that can be visualized in a web browser. </p> <p>Conclusion</p> <p>Our effort provides a central repository for storage and a platform for functional interrogation of the Northern bobwhite sequences providing comprehensive GO annotations, meta-data and a scaffold building pipeline. The Quail Genomics knowledgebase will be integrated with Japanese quail (<it>Coturnix coturnix</it>) data in future builds and incorporate a broader platform for these avian species. </p
