Molecular Evolution of Ultraviolet Visual Opsins and Spectral Tuning of Photoreceptors in Anemonefishes (Amphiprioninae)
Authors: Mitchell Laurie J , Cheney Karen L , Lührmann Martin , Marshall Justin , Michie Kyle , Cortesi Fabio 
Published: August 2021

Abstract
Many animals including birds, reptiles, insects, and teleost fishes can see ultraviolet (UV) light (shorter than 400 nm), which has functional importance for foraging and communication. For coral reef fishes, shallow reef environments transmit a broad spectrum of light, rich in UV, driving the evolution of diverse spectral sensitivities. However, the identities and sites of the specific visual genes that underly vision in reef fishes remain elusive and are useful in determining how evolution has tuned vision to suit life on the reef. We investigated the visual systems of 11 anemonefish (Amphiprioninae) species, specifically probing for the molecular pathways that facilitate UV-sensitivity. Searching the genomes of anemonefishes, we identified a total of eight functional opsin genes from all five vertebrate visual opsin subfamilies. We found rare instances of teleost UV-sensitive SWS1 opsin gene duplications that produced two functionally coding paralogs (SWS1α and SWS1β) and a pseudogene. We also found separate green sensitive RH2A opsin gene duplicates not yet reported in the family Pomacentridae. Transcriptome analysis revealed false clown anemonefish (Amphiprion ocellaris) expressed one rod opsin (RH1) and six cone opsins (SWS1β, SWS2B, RH2B, RH2A-1, RH2A-2, LWS) in the retina. Fluorescent in situ hybridization highlighted the (co-)expression of SWS1β with SWS2B in single cones, and either RH2B, RH2A, or RH2A together with LWS in different members of double cone photoreceptors (two single cones fused together). Our study provides the first in-depth characterization of visual opsin genes found in anemonefishes and provides a useful basis for the further study of UV-vision in reef fishes.

Summary
A recent article brought together the health benefits of unionization and working under collective agreements. It was noted how Canadian health promotion texts, reports and statements made no mention of unionization and working under collective agreements as promoting health. This was seen as a significant omission and reasons for this were considered. In this article this analysis is extended to consider how contributors to the flagship health promotion journal Health Promotion International (HPI) conceptualize unions, unionization and working under collective agreements as promoting health. Of 2443 articles published in HPI since its inception, 87 or 3.6% make mention of unions, unionization, collective agreements or collective bargaining, with most saying little about their promoting health. Instead, 20 make cursory references to unions or merely see them as providing support and engagement opportunities for individuals. Forty-five depict unions or union members as involved in a health promotion programme or activity carried out by the authors or by government agencies. Only 33 articles explicitly mention unions, unionization or collective agreements as potentially health promoting, representing 1.3% of total HPI content since 1986. We conclude that the health promoting possibilities of unionization and working under collective agreements is a neglected area amongst HPI contributors. Reasons for this are explored and an Organisation for Economic Cooperation and Development report on the importance of collective bargaining is drawn upon to identify areas for health promotion research and action.
Can International Investment Law Punish Investor’s Human Rights Violations? Copper Mesa, Contributory Fault and its Alternatives
Authors: Muchlinski Peter 
Published: August 2021

Abstract
Copper Mesa v Ecuador was the first award to assess the contribution of the investor’s human rights violations to the loss of their investment caused by the termination of its mining concession by the Respondent State. It found that the investor’s conduct acted as a contributory fault reducing the amount of compensation payable by the Respondent. It is argued that the contributory fault approach adopted in Copper Mesa is inappropriate for dealing with allegations of investor s human rights violations. By conflating causation, contributory fault and the unclean hands principle, the Tribunal effectively ignored the complex and unique questions of causation and responsibility involved in cases involving human rights violations by investors. The seriousness of proven investor human rights violations should render investor claims against resulting regulatory action inadmissible as a matter of international public policy. The note also addresses how investor conduct is treated in certain ‘new generation’ International Investment Agreement (IIA) provisions and concludes by considering how an IIA investor conduct clause should approach the human rights violations of investors.
Neuroethics and Animals: Report and Recommendations From the University of Pennsylvania Animal Research Neuroethics Workshop
Authors: Shriver Adam J , John Tyler M 
Published: August 2021

Abstract
Growing awareness of the ethical implications of neuroscience in the early years of the 21st century led to the emergence of the new academic field of “neuroethics,” which studies the ethical implications of developments in the neurosciences. However, despite the acceleration and evolution of neuroscience research on nonhuman animals, the unique ethical issues connected with neuroscience research involving nonhuman animals remain underdiscussed. This is a significant oversight given the central place of animal models in neuroscience. To respond to these concerns, the Center for Neuroscience and Society and the Center for the Interaction of Animals and Society at the University of Pennsylvania hosted a workshop on the “Neuroethics of Animal Research” in Philadelphia, Pennsylvania. At the workshop, expert speakers and attendees discussed ethical issues arising from neuroscience research involving nonhuman animals, including the use of animal models in the study of pain and psychiatric conditions, animal brain-machine interfaces, animal–animal chimeras, cerebral organoids, and the relevance of neuroscience to debates about personhood. This paper highlights important emerging ethical issues based on the discussions at the workshop. This paper includes recommendations for research in the United States from the authors based on the discussions at the workshop, loosely following the format of the 2 Gray Matters reports on neuroethics published by the Presidential Commission for the Study of Bioethical Issues.
Distinct Mitochondria-Mediated T-Cell Apoptosis Responses in Children and Adults With Coronavirus Disease 2019

Published: August 2021

Abstract

Background
Lymphopenia is a key feature for adult patients with coronavirus disease 2019 (COVID-19), although it is rarely observed in children. The underlying mechanism remains unclear.

Methods
Immunohistochemical and flow cytometric analyses were used to compare the apoptotic rate of T cells from COVID-19 adults and children and apoptotic responses of adult and child T cells to COVID-19 pooled plasma. Biological properties of caspases and reactive oxygen species were assessed in T cells treated by COVID-19 pooled plasma.

Results
Mitochondria apoptosis of peripheral T cells were identified in COVID-19 adult patient samples but not in the children. Furthermore, increased tumor necrosis factor-α and interleukin-6 in COVID-19 plasma induced mitochondria apoptosis and caused deoxyribonucleic acid damage by elevating reactive oxygen species levels of the adult T cells. However, the child T cells showed tolerance to mitochondrial apoptosis due to mitochondria autophagy. Activation of autophagy could decrease apoptotic sensitivity of the adult T cells to plasma from COVID-19 patients.

Conclusions
Our results indicated that the mitochondrial apoptosis pathway was activated in T cells of COVID-19 adult patients specifically, which may shed light on the pathophysiological difference between adults and children infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 ).
Antishear Therapy for Stevens–Johnson Syndrome and Toxic Epidermal Necrolysis: A Follow-up Study
Authors: Haravu Pranav N , Gottlieb Lawrence J , Vrouwe Sebastian Q 
Published: August 2021

Abstract
Stevens–Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) are life-threatening conditions best approached with multidisciplinary burn-equivalent care. There is a lack of consensus on wound management, in particular, whether to debride detached epidermis. Our center instituted “antishear” wound therapy 35 years ago, where detached skin is left in situ as a biologic dressing and a standardized protocol avoids shear forces to prevent further desquamation. Our center’s initial results showed outcomes comparable to SCORTEN predictions, but advancements in burn critical care necessitate a reevaluation of the antishear approach. A retrospective chart review was conducted for all patients admitted between June 2004 and May 2020 with a dermatologist-confirmed diagnosis of SJS/TEN (N = 51). All patients were treated with burn-equivalent critical care and antishear wound therapy. Standardized mortality ratios were calculated using the established SCORTEN, and newly developed ABCD-10, prediction models. Mean SCORTEN, ABCD-10, and %TBSA were 2.6, 2.0, and 28%. Overall mortality was 22%; SCORTEN score (P &lt; .001), ABCD-10 score (P &lt; .01), %TBSA involved (P = .02), and development of multisystem organ failure (P &lt; .001) correlated with increased mortality. Cohort-wide standardized mortality based on ABCD-10 was 1.18 (P = .79). Standardized mortality based on SCORTEN was 0.62 (P = .20) and 0.77 (P = .15) for patients with scores ≤3 and &gt;3; across the cohort it was 0.71 (P = .11), representing a 29% mortality reduction. Incorporating the antishear approach as part of burn-equivalent care for SJS/TENs led to outcomes comparable to those predicted for surgical debridement via SCORTEN. However, the antishear approach has the advantage of avoiding painful dressing changes, sedation, and general anesthesia required for surgical debridement.
Consumption Ideology
Authors: Schmitt Bernd , Brakus J Joško , Biraglia Alessandro 
Published: August 2021

AbstractIdeology plays a central role in consumer decisions, actions, and practices. While there have been numerous studies of ideological formations in specific consumption contexts, an integrative theoretical framework on consumption ideology has been missing. The theoretical framework presented in this article integrates systemic, social group, and social reality perspectives from social theory with prior consumer research to conceptualize consumption ideology as ideas and ideals that are related to consumerism and manifested in consumer behavior. Consumption ideology originates from conflicts between consumer desires and the system of consumerism. It is reflected in consumers’ lived experiences and expressed in social representations and communicative actions related to status-based consumption, brand affinity and antipathy, performed practices, and political consumption. By adapting to the market, consumers confirm the system, but when they resist, they accelerate conflicts in consumer experiences unless resistance is ideologically co-opted by the market. Three illustrative cases—upcycling, Zoom backgrounds, and the commercialization of TikTok—exemplify how the framework may be used to analyze consumption ideology and generate new research questions. The article concludes with future research programs that move beyond micro-theorizations to illuminate the broader role of ideology in contemporary consumerist society.

Abstract
Adenocarcinoma in a Meckel’s diverticulum is rare and difficult to diagnose preoperatively. We report the first case of a metachronous Krukenberg tumor from adenocarcinoma in a Meckel’s diverticulum. A 45-year-old woman was admitted for recurrent abdominal pain. Computed tomography scan showed a lesion with contrast enhancement, and a Meckel’s diverticulum-associated tumor was suspected. Double-ballon enteroscopy revealed intestinal stenosis and biopsy showed adenocarcinoma. Operative findings showed a Meckel’s diverticulum with tumor. Histopathological evaluation revealed well-differentiated adenocarcinoma, interrupted by ectopic gastric mucosa, diagnosed as adenocarcinoma in a Meckel’s diverticulum. Two years postoperatively, a multi-cystic mass with contrast enhancement was observed in the pelvis on imaging evaluation and oophorectomy performed. Histological examination of the resected ovary showed proliferation of atypical glandular ducts, consistent with metastatic adenocarcinoma. This case demonstrates that adenocarcinoma in a Meckel’s diverticulum may result in distant metastases and requires appropriate follow-up.
Dynamic changes in cell wall composition of mature sunflower leaves under distinct water regimes affect photosynthesis

Published: August 2021

AbstractIn previous work, we identified that exposure to limited water availability induced changes in cell wall composition of mature Helianthus annuus L. leaves that affected mesophyll conductance to CO2 diffusion (gm). However, it is unclear on which timescale these changes in cell wall composition occurred. Here, we subjected H. annuus to control (i.e. water availability), different levels of short-term water deficit stress (ST), long-term water deficit stress (LT), and long-term water deficit stress followed by gradual recoveries addressed at different timescales (LT-Rec) to evaluate the dynamics of modifications in the main composition of cell wall (cellulose, hemicelluloses, pectins and lignins) affecting photosynthesis. During gradual ST treatments, pectins enhancement was associated with gm decline. However, during LT-Rec, pectins content decreased significantly after only 5 h, while hemicelluloses and lignins amounts changed after 24 h, all being uncoupled from gm. Surprisingly, lignins increased by around 200% compared with control and were related to stomatal conductance to gas diffusion (gs) during LT-Rec. Although we suspect that the accuracy of the protocols to determine cell wall composition should be re-evaluated, we demonstrate for the first time that a highly dynamic cell wall composition turnover differently affects photosynthesis in plants subjected to distinct water regimes.

AbstractNsp15 is a uridine specific endoribonuclease that coronaviruses employ to cleave viral RNA and evade host immune defense systems. Previous structures of Nsp15 from across Coronaviridae revealed that Nsp15 assembles into a homo-hexamer and has a conserved active site similar to RNase A. Beyond a preference for cleaving RNA 3′ of uridines, it is unknown if Nsp15 has any additional substrate preferences. Here, we used cryo-EM to capture structures of Nsp15 bound to RNA in pre- and post-cleavage states. The structures along with molecular dynamics and biochemical assays revealed critical residues involved in substrate specificity, nuclease activity, and oligomerization. Moreover, we determined how the sequence of the RNA substrate dictates cleavage and found that outside of polyU tracts, Nsp15 has a strong preference for purines 3′ of the cleaved uridine. This work advances our understanding of how Nsp15 recognizes and processes viral RNA, and will aid in the development of new anti-viral therapeutics.
BSCI-05. ABL2-HSF1-E2F signaling axis promotes lung adenocarcinoma brain metastasis
Authors: Pendergast Ann Marie , Hoj Jacob , Mayro Benjamin 
Published: August 2021

Abstract
Brain metastases are the most common intracranial tumors in adults and are associated with increased patient morbidity and mortality. Limited therapeutic options are currently available for the treatment of brain metastasis. We have identified an actionable signaling pathway utilized by metastatic tumor cells whereby the transcriptional regulator Heat Shock Factor 1 (HSF1) drives a transcriptional program, divergent from its canonical role as the master regulator of the heat shock response, leading to enhanced expression of a subset of E2F transcription factor family gene targets. We showed that HSF1 is required for survival and outgrowth by metastatic lung cancer cells in the brain parenchyma. Unexpectedly, we identified the ABL2 tyrosine kinase as an upstream regulator of HSF1 protein expression, and showed that the Src-homology 3 (SH3) domain of ABL2 directly interacts with HSF1 protein at a non-canonical, proline-independent SH3 interaction motif. Importantly, knockdown of ABL2 impairs expression of HSF1 protein and HSF1-E2F transcriptional gene targets. Notably, we found that pharmacologic inhibition of the ABL kinases using selective ABL allosteric inhibitors, but not ATP-competitive inhibitors, ablates the physical interaction between ABL2 and HSF1, leading to markedly decreased expression of HSF1, E2F1 and E2F8 proteins in brain-metastatic lung cancer cells, and depletion of HSF1-E2F transcriptional targets. These findings highlight potential differences affecting intra- and inter-molecular protein-protein interactions induced by allosteric versus ATP-competitive kinase inhibitors that have important therapeutic implications. Importantly, the targetable nature of the ABL2-HSF1-E2F signaling network identifies ABL allosteric inhibitors as a potentially effective therapy for the treatment of metastatic lung cancers characterized by high expression of HSF1.
BSCI-09. Multiomic single cell analysis reveals emerging principles of tumor immune microenvironment inherent to NSCLC brain metastases

Published: August 2021

Abstract
Brain is one of the most common sites for distant metastasis of lung cancer. Treatment naïve lung cancer patients diagnosed with brain metastasis are left with very limited options. Checkpoint inhibition is a powerful immunotherapy strategy but delivers benefit only to a small population of patients. Here we harnessed the power and resolution of single cell RNA sequencing and single cell TCR/BCR sequencing to investigate the tumor immune microenvironment (TIME) of NSCLC brain metastases. We enrolled treatment naïve lung cancer patients with brain metastasis. The enrolled subjects covered different histology types and driver gene mutation status. We revealed the emerging principles of innate and adaptive immune components inherent to NSCLC brain metastases. We also uncovered several significant intercellular communication patterns that potentiates cancer cell seeding and fosters cancer cell proliferation. Those results served as a starting point to design optimal immunotherapy strategies for advanced lung cancer patients with limited options.
TRLS-02. Trial in Progress: A Multicenter Phase 3 Study to Establish the Diagnostic Performance of 18F-Fluciclovine PET in Detecting Recurrent Brain Metastases after Radiation Therapy (REVELATE)
Authors: Teoh Eugene , Chaglassian Alain , Tainer Nancy 
Published: August 2021

Abstract

Background
Brain metastases occur in up to 40% of patients with cancer and are associated with poor prognosis and considerable levels of recurrence. Consequently, close follow-up with serial brain MRI is performed post-treatment to monitor for recurrent disease. Although conventional MRI (CE-T1-weighted and FLAIR/T2-weighted) is the recommended follow-up modality, it has poor specificity with limited ability to differentiate between true disease recurrence and treatment-related changes such as radiation necrosis. Therefore, alternative imaging options are sought in order to help physicians confidently diagnose treatment-related changes and thus reliably stratify the risk of continuation of a therapeutic regimen, especially given the morbidity associated with current treatments. Amino acid PET imaging agent, 18F-fluciclovine, has increased uptake in brain tumors relative to normal tissue and may be useful for detecting recurrent brain metastases.

Methods
NCT04410133 is a prospective, open-label, single-arm, single-dose (185 MBq ±20%) study with a primary objective to confirm the diagnostic performance of 18F-fluciclovine PET (read with conventional MRI for anatomical reference) for detection of recurrent brain metastases where MRI is equivocal.
Approximately 150 subjects with solid tumor brain metastases who have undergone radiation therapy will be enrolled in this multicenter trial (~18 US sites) if they have a lesion considered equivocal on MRI that requires further confirmatory diagnostic procedures such as biopsy/neurosurgical intervention or clinical follow-up. Subjects will undergo 18F-fluciclovine PET &lt;28 days after the equivocal MRI and 2–21 days pre-biopsy/neurosurgical intervention. Clinical follow-up will occur for 6m post-18F-fluciclovine PET. Secondary objectives include evaluation of subject- and lesion-level 18F-fluciclovine negative and positive percent agreement (equivalent to specificity and sensitivity respectively) for recurrent brain metastases, inter-reader and intra-reader agreement, and safety evaluations. Enrolment began in October 2020 and the trial is open at the time of submission.

Published: August 2021

Abstract

Background
Brain metastases are the most common intracranial tumors in adults, with a very poor prognosis, and poses distinct clinical challenges. This study aimed to develop a more accurate prognostic nomogram for predicting overall survival (OS) of patients with Brain Metastases.

Methods
We conducted a retrospective analysis of 1062 patients with brain metastases at the Sun Yat-sen University Cancer Center (SYSUCC, Guangzhou, China) between January 2010 and January 2018, Among them, 331 patients underwent surgery to remove brain metastases. Kaplan–Meier analysis was performed to screen for potential clinical variables that could be used to establish the nomogram for predicting overall survival.

Results
We found that age,gender, whether to remove intracranial lesions, radiotherapy, ECOG were independent prognostic factors for predicting the overall survival with brain metastases,and surgical resection for brain metastatic lesions could significantly improve OS,but only in certain groups of patients with brain metastases can benefit from intracranial lesion resection, such as no extracranial metastasis. And patients with brain metastases whose primary tumor is lung adenocarcinoma or breast cancer are more likely to benefit from surgery in terms of overall survival time.A nomogram for predicting 1- and 2-year overall survival rates was constructed, which exhibited good accuracy in predicting overall survival.

Conclusion
Through statistical analysis, we have found the factors related to the surgical benefit of patients with brain metastases, and established a prognostic nonogram,This nomogram may be used to guide individual treatments and in selecting an appropriate patient population for clinical trials.
