Poe’s References to the Visual Arts
Authors: Golahny Amy 
Published: June 2021

Abstract
Poe’s references to the visual arts have long been noted, but rarely examined for personal and original content. Barbara Cantalupo’s recent monograph is an exception in this regard and proposes that Poe’s interest in the arts was deep and generally concerned beauty and aesthetic issues. Facile with aspects of antiquity, the Renaissance, and the Baroque, Poe had an enthusiasm for artists working in the United States that was more personal than his interest in those from the European past. He knew firsthand works by Joshua Shaw, Clark Mills, and Hiram Powers. Without traveling to continental Europe, Poe became familiar with Renaissance and Baroque art through his reading and by viewing works in New York and Philadelphia. He was sufficiently familiar with foremost artists and antiquities to make references that strengthened his characters and settings. In commenting on exhibits in New York, Poe revealed his opinions, both positive and negative. Conversant with the typical qualities of major categories of art, Poe did not stray from the generally received information about past art but evidently relied on his own observations for current art. Ultimately, Poe’s interest in the visual arts depended on how he could use painting and sculpture in his writings.
Thrilling Vagueness and Pure Abstractions
Authors: Zuber Devin Phillip 
Published: June 2021

Abstract
If we are to position Poe’s concept of “graphicality” as hovering at the juncture between the verbal and the visual—a gesture toward painting at the same time that it indicates a literary art of description, or ekphrasis—criticism has tended to overlook the centrality of Emanuel Swedenborg’s so-called “doctrine of correspondences” within American art discourses of the 1830s and ’40s. This essay explores the corresponding Swedenborgian valences behind Poe’s own graphicality, putting his work in context of three critical figures in Poe’s orbit who respectively mediated, to one degree or another, Swedenborgian theories: George Bush, the mesmerist and New York University professor of Hebrew and Oriental languages; Thomas Holley Chivers, the southern poet, and close friend of Poe’s; and finally, Christopher Pearse Cranch, the landscape painter. The essay concludes with a brief close reading of Poe’s iconic tale “The Fall of the House of Usher,” the only published work in Poe which explicitly mentions a book by Swedenborg (his “spiritualist” classic from 1758, Heaven and Hell).

Background:Hair greying is a hallmark of aging generally believed to be irreversible and linked to psychological stress.Methods:Here, we develop an approach to profile hair pigmentation patterns (HPPs) along individual human hair shafts, producing quantifiable physical timescales of rapid greying transitions.Results:Using this method, we show white/grey hairs that naturally regain pigmentation across sex, ethnicities, ages, and body regions, thereby quantitatively defining the reversibility of greying in humans. Molecularly, grey hairs upregulate proteins related to energy metabolism, mitochondria, and antioxidant defenses. Combining HPP profiling and proteomics on single hairs, we also report hair greying and reversal that can occur in parallel with psychological stressors. To generalize these observations, we develop a computational simulation, which suggests a threshold-based mechanism for the temporary reversibility of greying.Conclusions:Overall, this new method to quantitatively map recent life history in HPPs provides an opportunity to longitudinally examine the influence of recent life exposures on human biology.Funding:This work was supported by the Wharton Fund and NIH grants GM119793, MH119336, and AG066828 (MP).

Published: June 2021

Introduction: Medical students are future doctor candidates. They must learn about diseases, infectious and non-infectious, during their education period. What the students have to learn is being packaged in integrated blocks. Tutorial is one of the Problem Based Learning (PBL) methods in medical education whose activities are entirely learner-centered. It is a focus group discussion (FGD) based activity, consist of 7-8 students and supervised by one lecturer called tutor who will provide an assessment at the end of each session. The aim of this study is to characterize whether gender and place of residence affect the student’s tutorial score.
Methods: This retrospective cross sectional study conducted from April to May 2021 at the Faculty of Medicine, Universitas Kristen Indonesia, Jakarta-Indonesia. All data of active students gathered from education manager office. Simple descriptive statistic operation conducted whenever necessary. Data about place of residence obtained electronically using simple G-form survey.
Result and Discussion: Data comes from 607 active students were eligible for further analysis. Total mean of tutorial score based on their batch (2017, 2018, 2019, 2020): 15.53; 16.24; 15.82 and 15.06. The highest mean tutorial score is 16.34 in the group of female students who live in their own home from the class of 2018 and the lowest score is 14.74 in the group of male student who live in the boarding house from the class 2020.
Conclusion: Female students have a higher mean tutorial score compared to male students, and those who live at home with their parents also have a higher average score than those who live in a boarding house, by themselves. As our students become more senior, the better their tutorial scores.

Published: June 2021

Abstract

Objectives
Pilots with coronary artery disease (CAD) are at increased risk of myocardial infarction, stroke, and possibly death. Return to flying duties may be considered after a detailed risk assessment. The aim of this retrospective case series is to describe the return to flying duty process.

Methods
We conducted a retrospective case review of pilots diagnosed with CAD at the Institute of Aviation Medicine (IAM), Royal Malaysian Air Force (RMAF) in October 2020.

Results
Thirteen cases of CAD were included in the review. Ten pilots were diagnosed after developing acute coronary syndrome; the remaining three pilots were diagnosed during a routine medical examination via an exercise stress test. Twelve pilots required a revascularization procedure. A total of 11 pilots (84.6%) were recertified for flying duties, while another two were disqualified. The duration to recertification for these 11 pilots was between three months and one year.

Conclusions
The risk assessment was initiated with initial risk-stratification using population-appropriate risk calculator combined with the 4 × 4 aeromedical risk matrix. The reassessment of return to flying after coronary artery disease must be carried out no sooner than six months after the event. Pilots must be hemodynamically stable with no evidence of significant inducible ischemic left and a minimum 50% of ventricular ejection fraction (LVEF). A follow-up is recommended at the initial six months after recertification and then annually with a routine noninvasive cardiac assessment.

AbstractHerein, we demonstrate that organic, single‐electron oxidant in the presence of diarylprolinol silylether type catalyst serves as a tool for the transformation of electron‐rich enamines to iminium ions. These iminium ions take part in a subsequent Michael‐initiated ring‐closure (MIRC) reaction with in situ present nucleophile giving rise to overall cyclopropanation reaction of saturated aldehydes. Stereodefined cyclopropanes are obtained in high yields and selectivities. This one‐pot transformation represents the additional example of saturated aldehydes being used in the coupled one‐pot processes.magnified image
Sex‐linked gene expression and the emergence of hermaphrodites in Carica papaya
Authors: Chae Taylor , Harkess Alex , Moore Richard C. 
Published: June 2021

PremiseOne evolutionary path from hermaphroditism to dioecy is via a gynodioecious intermediate. The evolution of dioecy may also coincide with the formation of sex chromosomes that possess sex‐determining loci that are physically linked in a region of suppressed recombination. Dioecious papaya (Carica papaya) has an XY chromosome system, where the presence of a Y chromosome determines maleness. However, in cultivation, papaya is gynodioecious, due to the conversion of the male Y chromosome to a hermaphroditic Yh chromosome during its domestication.MethodsWe investigated gene expression linked to the X, Y, and Yh chromosomes at different floral developmental stages to identify differentially expressed genes that may be involved in the sexual transition of males to hermaphrodites.ResultsWe identified 309 sex‐biased genes found on the sex chromosomes, most of which are found in the pseudoautosomal regions. Female (XX) expression in the sex‐determining region was almost double that of X‐linked expression in males (XY) and hermaphrodites (XYh), which rules out dosage compensation for most sex‐linked genes; although, an analysis of hemizygous X‐linked loci found evidence of partial dosage compensation. Furthermore, we identified a candidate gene associated with sex determination and the transition to hermaphroditism, a homolog of the MADS‐box protein SHORT VEGETATIVE PHASE.ConclusionsWe identified a pattern of partial dosage compensation for hemizygous genes located in the papaya sex‐determining region. Furthermore, we propose that loss‐of‐expression of the Y‐linked SHORT VEGETATIVE PHASE homolog facilitated the transition from males to hermaphrodites in papaya.

Published: June 2021

AbstractA series of Mn–Ce–Fe–Co–Ox/P84 (polyimide) catalytic filter materials by in situ method (ISM) were investigated for the low‐temperature catalytic activities for NO and elemental mercury Hg0in the simulated flue fixed‐bed system, especially under mixed atmosphere conditions with water and sulfur. The influence of Fe and Co doping ratio, Fe of loading sequence, and the types of precursors are systematically investigated under 8% H2O and 75 ppm SO2atmosphere. Results showed that the toxic effects of H2O and SO2on the catalytic filter materials were obvious. When using Mn–Ce–Fe–Co–Ox/P84 catalytic filter materials (Mn/Ce/Fe/Co = 4:5:0.5:0.5, in mol), the NO reduction and Hg0oxidation decreased from 95.0% to 40.0% and 55%, respectively. As the molar ratio of Fe/Co increased, the anti‐sulfur and water resistance activity of catalytic filter materials showed a trend of first increasing and then decreasing. Active components of Mn–Ce–Fe–Co–Ox/P84 (Mn/Ce/Fe/Co = 4:5:1.25:1 in mol) could achieve 81.0% of NO reduction and 79.2% Hg0oxidation simultaneously. As the molar ratio of Fe/Co increased, the NOxsynergistic Hg0conversion efficiency of the catalytic filter materials was first promoted and then suppressed. Comparing the order of Fe impregnation and the types of Fe precursors revealed that using Fe(NO3)3to generate Fe2O3was more active than directly using Fe2O3at 170°C to 260°C. Electron transfer between Mn, Ce and Fe increases the high ratio of Mn4+/(Mn4++Mn3+) and Ce3+/(Ce3++Ce4+) which may enhance the sulphur and water resistance of the catalytic filter materials.

AbstractNanostructures of the multimetallic catalysts offer great scope for fine tuning of heterogeneous catalysis, but clear understanding of the surface chemistry and structures is important to enhance their selectivity and efficiency. Focussing on a typical Pt−Pd−Ni trimetallic system, we comparatively examined the Ni/C, Pt/Ni/C, Pd/Ni/C and Pt−Pd/Ni/C catalysts synthesized by impregnation and galvanic replacement reaction. To clarify surface chemical/structural effect, the Pt−Pd/Ni/C catalyst was thermally treated at X=200, 400 or 600 °C in a H2reducing atmosphere, respectively termed as Pt−Pd/Ni/C−X. The as‐prepared catalysts were characterized complementarily by XRD, XPS, TEM, HRTEM, HS‐LEIS and STEM‐EDS elemental mapping and line‐scanning. All the catalysts were comparatively evaluated for benzaldehyde and styrene hydrogenation. It is shown that the “PtPd alloy nanoclusters on Ni nanoparticles” (PtPd/Ni) and the synergistic effect of the trimetallic Pt−Pd−Ni, lead to much improved catalytic performance, compared with the mono‐ or bi‐ metallic counterparts. However, with the increase of the treatment temperature of the Pt−Pd/Ni/C, the catalytic performance was gradually degraded, which was likely due to that the favourable nanostructure of fine “PtPd/Ni” was gradually transformed to relatively large “PtPdNi alloy on Ni” (PtPdNi/Ni) particles, thus decreasing the number of noble metal (Pt and Pd) active sites on the surface of the catalyst. The optimum trimetallic structure is thus the as synthesised Pt−Pd/Ni/C. This work provides a novel strategy for the design and development of highly efficient and low‐cost multimetallic catalysts, e. g. for hydrogenation reactions.

Published: June 2021

AbstractIn this contribution, we report on a class of emitters based on bridged oxo‐ and/or thioethers revealing striking photoluminescence properties in fluid solution and in the solid state. In total, nine compounds were investigated concerning their photophysical properties, which were interpreted by quantum chemical calculations. To our delight, we discovered compounds possessing nearly identical photoluminescence quantum yields (ΦF) in solution and in the solid state, which has been rarely reported so far. Besides these efforts, we shed light on the influence of polymorphism and solvent polarity on the emission properties. In addition, an in‐depth X‐ray diffractometric analysis was conducted to correlate molecular packing in the crystal with differences in the photophysical properties.

AbstractViscosity plays a significant role in the utilization of bio‐oil as a liquid transportation fuel. This study investigated the influence of temperature on the viscosity of bio‐oils derived from white pine and from Norway spruce needles. The bio‐oils were produced by pyrolyzing the biomass samples in a fixed‐bed batch reactor at a temperature of 500 °C for 30 min. The viscosity of the bio‐oils was determined at a temperature range of 20–80 °C. The bio‐oil yield was estimated to be 36.32% and 28.84% for white pine and Norway spruce needles, respectively. The viscosity of bio‐oils derived from white pine and Norway spruce needles decreased from 177.67 to 54 cP and from 161.17 to 37.67 cP, respectively, as the temperature increased from 20 to 80 °C. Among the three models (Arrhenius, modified Williams–Landel–Ferry, and the power law) used to describe the temperature‐viscosity relationship of the bio‐oils, the Arrhenius model presented the best fit for the experimental data with activation energy of 16.80 and 20.79 kJ/mol–1 for bio‐oils derived from white pine and Norway spruce needles, respectively. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

AbstractAimRhoA/Rho kinase pathway is essential for regulating cytoskeletal structure. Although its effect on normal neurite outgrowth has been demonstrated, the role of this pathway in seizure‐induced neurite injury has not been revealed. The research examined the phosphorylation level of RhoA/Rho kinase signaling pathway and to clarify the effect of fasudil on RhoA/Rho kinase signaling pathway and neurite outgrowth in kainic acid (KA)‐treated Neuro‐2A cells and hippocampal neurons.MethodWestern blotting analysis was used to investigate the expression of key proteins of RhoA/Rho kinase signaling pathway and the depolymerization of actin. After incubated without serum to induce neurite outgrowth, Neuro‐2A cells were fixed, and immunofluorescent assay of rhodamine‐phalloidin was applied to detect the cellular morphology and neurite length. The influence of KA on neurons was detected in primary hippocampal neurons. Whole‐cell patch clamp was conducted in cultured neurons or hippocampal slices to record action potentials.ResultKA at the dose of 100–200 μmol/L induced the increase in phosphorylation of Rho‐associated coiled‐coil‐containing protein kinase and decrease in phosphorylation of Lin11, Isl‐1 and Mec‐3 kinase and cofilin. The effect of 200 μmol/L KA was peaked at 1–2 hours, and then gradually returned to baseline after 8 hours. Pretreatment with Rho kinase inhibitor fasudil reversed KA‐induced activation of RhoA/Rho kinase pathway and increase in phosphorylation of slingshot and 14‐3‐3, which consequently reduced the ratio of G/F‐actin. KA treatment induced inhibition of neurite outgrowth and decrease in spines both in Neuro‐2a cells and in cultured hippocampal neurons, and pretreatment with fasudil alleviated KA‐induced neurite outgrowth inhibition and spine loss.ConclusionThese data indicate that inhibiting RhoA/Rho kinase pathway might be a potential treatment for seizure‐induced injury.

AbstractObjectivesTo investigate the outcomes of deferred coronary revascularization in patients with non‐significant in‐stent restenosis (ISR) by physiological assessment.BackgroundThe pathophysiology and natural history of ISR is markedly different from de‐novo stenoses. There is a paucity of data on the safety of deferral of revascularization of ISR using physiological assessment.MethodsIn this single centre study, using a propensity‐score matched analysis, we compared the long‐term clinical outcomes of patients with ISR and de‐novo disease deferred based on intracoronary physiology. Matching was on a 1:2 basis of ISR to de‐novo stenosis. The primary end point was major adverse cardiovascular events (MACE) a composite of all‐cause mortality, target lesion revascularization or target vessel myocardial infarction at 36 months.ResultsMatched cohorts of 56 ISR and 112 de‐novo stenoses were analyzed. The median percentage stenosis was 50% in both groups (p = 0.403). Deferral was based on fractional flow reserve (FFR). The mean FFR was 0.86 across both groups (p = 0.942). At 36‐months, freedom from MACE was similar between groups; 86.2% versus 92.8% log rank p=0.180 for ISR and de‐novo lesions, respectively. Neither were there differences in the individual components of MACE.ConclusionsDeferral of coronary revascularization in patients with ISR based on its functional impact is associated to similar long‐term safety as in de‐novo coronary stenosis.
