Published: February 2022

AbstractThe western massasauga (Sistrurus tergeminus) is a small pit viper with an extensive geographic range, yet observations of this species are relatively rare. They persist in patchy and isolated populations, threatened by habitat destruction and fragmentation, mortality from vehicle collisions, and deliberate extermination. Changing climates may pose an additional stressor on the survival of isolated populations. Here, we evaluate historic, modern, and future geographic projections of suitable climate for S. tergeminus to outline shifts in their potential geographic distribution and inform current and future management. We used maximum entropy modeling to build multiple models of the potential geographic distribution of S. tergeminus. We evaluated the influence of five key decisions made during the modeling process on the resulting geographic projections of the potential distribution, allowing us to identify areas of model robustness and uncertainty. We evaluated models with the area under the receiver operating curve and true skill statistic. We retained 16 models to project both in the past and future multiple general circulation models. At the last glacial maximum, the potential geographic distribution associated with S. tergeminus occurrences had a stronghold in the southern part of its current range and extended further south into Mexico, but by the mid‐Holocene, its modeled potential distribution was similar to its present‐day potential distribution. Under future model projections, the potential distribution of S. tergeminus moves north, with the strongest northward trends predicted under a climate scenario increase of 8.5 W/m2. Some southern populations of S. tergeminus have likely already been extirpated and will continue to be threatened by shifting availability of suitable climate, as they are already under threat from desertification of grasslands. Land use and habitat loss at the northern edge of the species range are likely to make it challenging for this species to track suitable climates northward over time.

AbstractAimsHeart transplantation (HT) is an effective therapeutic option for end‐stage heart failure. Infection is a major cause of morbidity and mortality after HT. Sarcopenia, defined as the loss of muscle mass and strength, is a common comorbidity in HT candidates with end‐stage heart failure. However, the effects of sarcopenia on the occurrence of post‐HT infections are not well understood. Therefore, we explored the association between the skeletal muscle mass and post‐transplant infections in adult HT recipients.Methods and resultsWe retrospectively examined the records of 135 patients who underwent HT between August 2007 and November 2019 at our institution. Pre‐transplant computed tomography was used to calculate the skeletal muscle index (SMI) at the level of the third lumbar vertebra. Muscle wasting was defined as the SMI of the lowest sex‐based tertiles. The primary endpoint was infections within 6 months of HT. The study included 109 patients (80 men, mean age: 41.6 ± 12.0 years): 37 patients in the muscle wasting group and 72 patients in the non‐muscle wasting group. The mean SMI values in the muscle wasting and non‐muscle wasting groups were 29.9 ± 4.8 cm2/m2 and 40.7 ± 6.7 cm2/m2, respectively. Prior to HT, 108 (99.1%) patients were on left ventricular assist device support, and during that support, the rate of late right heart failure was significantly higher in the muscle wasting group than non‐muscle wasting group (P = 0.012). Sixteen infections occurred within 6 months of HT. The most common infection sites included the respiratory tract (n = 5) and the upper gastrointestinal tract (n = 5), followed by the urinary tract (n = 4). Overall, 10 patients experienced infections in the muscle wasting group (27.0%) and 6 in the non‐muscle wasting group (8.3%) (P = 0.009). Two patients in the muscle wasting group required intensive care unit admission, compared to none in the non‐muscle wasting group. Low skeletal muscle mass was associated with infections in the univariate and multivariate logistic regression models (hazard ratio: 3.68, 95% confidence interval: 1.19–11.3; P = 0.023). However, the duration of all‐cause mortality within 3 years did not differ between the groups (P = 0.56).ConclusionsLow skeletal muscle mass is a predictor of post‐HT infections within 6 months of HT.

AbstractWeakly magnetic hematite (α‐Fe2O3) nanoparticles were synthesized by heating an amorphous polymer supported iron(III) complex (Fe_POL) at 400 °C for 4 h in air. The growth of nanoparticles (NPs) was studied by PXRD, heating the polymer from 150 °C to 400 °C at 25 °C intervals, revealing that, at all temperatures, the only crystalline phase detected is hematite. Conversely, annealing of Fe_POL at 400 °C for 4 h under nitrogen, yielded a material containing wüstite (FeO) as the only crystalline phase, supported onto pyrolised acrylamidic polymer. The synthesized materials were characterized by TXRF, PXRD, SEM‐EDS, XPS, Raman and FTIR spectroscopy as well as by magnetic analysis. Differently from natural micrometric hematite, synthesised nano‐hematite turned out to be an efficient and recyclable catalyst for the hydrogenation of nitroarenes to the corresponding anilines.
Study of [2]‐ and [3]Rotaxanes Obtained by Post‐Synthetic Aminolysis of a Kinetically Stable Carbonate‐Containing Pseudorotaxane

Published: February 2022

AbstractHere is reported the synthesis and study of dibenzo‐24‐crown‐8 (DB24C8)‐based [2]‐ and [3]rotaxanes that contain an ammonium as the best molecular station and carbamate moieties as secondary molecular stations. The common post‐interlocking synthesis relies on the aminolysis of the N‐succinimidyl carbonate extremity of an activated though insulated pseudorotaxane. The N‐succinimidyl carbonate‐based thread's extremity proved to be small enough to allow the slow slippage of the DB24C8 around the thread and large enough to allow insulation of the kinetically stable pseudorotaxane. Due to its sensitivity towards amine compounds, the activated carbonate end of the encircled thread allowed post‐interlocking aminolysis‐based conversion into mechanically interlocked rotaxanes by providing the same way the carbamate secondary station for the DB24C8 in the thread backbone. Translation of the DB24C8 along the threaded axle between the two molecular stations was investigated.

AbstractBackgroundWe aimed to evaluate patients suitable for definitive radiation therapy (DRT) and liver local therapy (LLT) in addition to palliative chemotherapy (PCT) among those with de novo liver metastatic nasopharyngeal carcinoma (lmNPC).MethodsThe overall survival (OS) and progression‐free survival (PFS) rates were calculated and compared in 610 patients with lmNPC.ResultsBoth the PCT+DRT and PCT+DRT+LLT groups had better survival outcomes than the PCT group. Among patients with complete response/partial response (CR/PR) after PCT, no significant differences in survival rates were observed between those treated with PCT+DRT and PCT+DRT+LLT (2‐year PFS: 27.0% vs. 32.9%, p = 0.263). Among patients with progressive disease/stable disease (PD/SD) after PCT, significantly better survival rates were observed in patients treated with PCT+DRT+LLT.ConclusionsDRT might benefit patients with lmNPC regardless of the tumor response after PCT. For patients with CR/PR, LLT might not be needed. For patients with PD/SD, LLT might improve survival outcomes.

AbstractAs improving equity becomes prioritized in higher education, Offices of Institutional Research (OIRs) find themselves in a central position to identify and address educational inequities faced by racially minoritized students. However, their potential to serve as a catalyst for organizational change has yet to be fulfilled. In this study, we present a critical discourse analysis of mission statements to understand how these OIRs describe their function and purpose in the California Community Colleges system. Results are based on 108 reviewed statements. These results reveal a limited discourse around race and equity. None of the statements in our sample included the word race or any words stemming from it such as racism or racial disparity. The majority (86%) of statements omitted equity from their purpose, failing to describe how OIRs can serve to improve equitable outcomes in community college. Our work prompts the field to reimagine their role within the community college they serve by becoming race‐conscious and equity‐minded in the ways they articulate their role and function as major hubs of institutional data.

AbstractThis article describes how a large Institutional Research and Decision Support (IRDS) office engaged in efforts to promote culturally responsive and inclusive institutional research (IR) practices that take into account the increasingly diverse student, faculty, and staff populations we serve. We describe how we developed a diversity, equity and inclusion (D.E.I.) strategic plan that addressed the following: (a) ensuring our Mission Statement reflects our commitment to diversity; (b) applying an equity lens to our work; (c) supporting campus‐wide D.E.I. efforts while helping the campus live out a commitment to D.E.I.; (d) implementing internal office practices to support the recruitment and retention of a diverse team; and (e) ensuring IR professionals have access to and opportunities to learn about current trends in equity and inclusion. Our approach was guided by Kendi's conceptualization of antiracism, and we examine how we have opportunities to make antiracist decisions in various aspects of our work, including how we frame IR, analyze and label data, and interpret results given local contexts and structural inequities.
DRAINMOD simulation of drain spacing impact on canola yield in heavy clay soils in the Canadian prairies

Published: February 2022

AbstractExcess moisture within the root zone due to the shallow water table is a leading cause of crop loss in Manitoba. In this study, the ability of the DRAINMOD model to predict water table depth (WTD) in clayey soil was evaluated using measured field data from the 2019 and 2020 canola‐growing seasons in Arborg, Manitoba, Canada. Statistical analysis and graphical plots showed close agreement between the measured and simulated WTD with an overall coefficient of determination (R2), root mean square error (RMSE), mean average error (MAE) and mean bias error (MBE) of 0.93, 9.84 cm, 7.06 cm and −0.13 cm, respectively. Since the model simulation was deemed satisfactory, the model was run with 30‐year historical climate data to assess the impacts of different drain spacing on canola yield. Simulation results showed that the average surface runoff increased while average drainage and relative canola yield decreased as drain spacing increased. The simulation results suggest that long‐term average yield would be maximized by close drain spacing ≤ 15 m. Economic analysis showed that 10 m drain spacing would maximize the return on investment. The need for long‐term simulations to develop appropriate site‐specific water management strategies is demonstrated.

Published: February 2022

AbstractThe auxin‐mimicking herbicide quinclorac controls crabgrass (Digitaria spp.) after emergence in cool‐ and warm‐season turfgrass species. Quinclorac resistance has been confirmed in smooth [Digitaria ischaemum (Schreb.) Muhl.] and large crabgrass [Digitaria sanguinalis (L.) Scop.]. Two Mississippi smooth crabgrass populations have been confirmed as quinclorac‐resistant. Field experiments were conducted to evaluate programmatic approaches to control one of these populations. Treatments included the sequential application of pre‐emergence herbicides on 17 Feb. and 10 Apr. 2020, and 25 Feb. and 6 Apr. 2021, alone or with 0.84 kg quinclorac ha–1 applied postemergence on 10 April 2020 and 6 April 2021, then a second application of quinclorac alone on 18 June 2020 and 16 June 2021. Pre‐emergence treatments included 0.05 kg indaziflam ha–1, 0.84 kg prodiamine ha–1, 0.56 kg dithiopyr ha–1, and 0.47 kg prodiamine ha–1 + 0.21 kg imazaquin ha–1 + 0.73 kg simazine ha–1. Commercial standards applied on 10 Apr. and 18 June 2020, and 6 Apr. and 16 June 2021 included 0.16 kg pinoxaden ha–1 and 2.27 kg monosodium methanearsonate ha–1. Four weeks after the last application, all treatments except quinclorac (2020 and 2021), dithiopyr (2020), and pinoxaden (2020) controlled quinclorac‐resistant smooth crabgrass by >90%. Various standard pre‐emergence herbicides adequately controlled the resistant population. Quinclorac combined with pre‐emergence strategies provided greater control of smooth crabgrass than quinclorac alone. Ongoing research is investigating the mechanism of quinclorac resistance. Future research should screen a wider distribution of populations and investigate cross‐ and multiple resistance.
The Mineralization Regulator ANKH Mediates Cellular Efflux of ATP, Not Pyrophosphate

ABSTRACT
The plasma membrane protein ankylosis homologue (ANKH, mouse ortholog: Ank) prevents pathological mineralization of joints by controlling extracellular levels of the mineralization inhibitor pyrophosphate (PPi). It was long thought that ANKH acts by transporting PPi into the joints. We recently showed that when overproduced in HEK293 cells, ANKH mediates release of large amounts of nucleoside triphosphates (NTPs), predominantly ATP, into the culture medium. ATP is converted extracellularly into PPi and AMP by the ectoenzyme ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1). We could not rule out, however, that cells also release PPi directly via ANKH. We now addressed the question of whether PPi leaves cells via ANKH using HEK293 cells that completely lack ENPP1. Introduction of ANKH in these ENPP1-deficient HEK293 cells resulted in robust cellular ATP release without the concomitant increase in extracellular PPi found in ENPP1-proficient cells. Ank activity was previously shown to be responsible for about 75% of the PPi found in mouse bones. However, bones of Enpp1−/− mice contained &lt;2.5% of the PPi found in bones of wild-type mice, showing that Enpp1 activity is also a prerequisite for Ank-dependent PPi incorporation into the mineralized bone matrix in vivo. Hence, ATP release precedes ENPP1-mediated PPi formation. We find that ANKH also provides about 25% of plasma PPi, whereas we have previously shown that 60% to 70% of plasma PPi is derived from the NTPs extruded by the ABC transporter, ABCC6. Both transporters that keep plasma PPi at sufficient levels to prevent pathological calcification therefore do so by extruding NTPs rather than PPi itself. © 2022 American Society for Bone and Mineral Research (ASBMR).

AbstractExtant literature suggests that consumers derive more happiness from experiences (e.g., vacations) than from material possessions (e.g., furniture). However, this literature typically pits material against experiential consumption, treating them as a single bipolar construct of their relative dominance: more material or more experiential. This focus on relative dominance leaves unanswered questions regarding how different levels of material and experiential qualities each contribute to happiness. Four preregistered studies (N = 3,288), using hundreds of product categories, measured levels of material and experiential qualities using two unipolar items. These studies investigate recalled, evoked, and anticipated happiness. Results show a more nuanced view of the experiential advantage that is critical for future research and consumer theory: material and experiential qualities both have positive relationships with happiness. Further, there is no inherent trade‐off between experiential and material qualities: consumers can enjoy consumption that is high on both (e.g., swimming pools and home improvements).

AbstractBACKGROUNDPalladium particles with a size of 2 nm were obtained by laser electrodispersion (LED) and used to prepare the Pd‐ZnHZSM‐5(LED) catalyst (Pd = 0.0005 wt%). The deposition of the LED palladium particles on the surface of ZnHZSM‐5 provided a high dimethyl ether (DME) conversion into liquid hydrocarbons; the percentage of the unreacted intermediate (methanol) decreased by an order of magnitude and the selectivity for i‐alkanes increased (more than 80 wt%). The Pd‐ZnНZSM‐5(LED) catalyst showed higher activity and selectivity than the traditional Pd‐ZnНZSM‐5 catalyst (impregnation).RESULTSThe features of the catalytic action of Pd‐ZnHZSM‐5(LED) are associated with the high density of nanosized Pd0 and Pd2+ phases on the ZnHZSM‐5 surface. The LED particles are immersed in the surface of the zeolite to a maximum depth of 0.5 nm and do not penetrate deep into the pores of the zeolite. In Pd‐ZnНZSM‐5(LED), the zinc sites and palladium sites are separate. On Brønsted acid sites and zinc sites in the micropores of the zeolite occure target reactions. Part of arenes and unreacted alkenes exit the pores of zeolite are hydrogenated on the palladium. The product obtained on Pd‐ZnHZSM‐5(LED) is characterized by a high content of i‐alkanes (more than 80 wt%) and a low content of arenes (no more than 5 wt%).CONCLUSIONThe results demonstrate the high promise of the LED method for the preparation of high‐performance catalysts with ultra‐low content of noble metal for conversion of oxygenates to synthetic liquid hydrocarbons with a high yield of i‐alkanes and low yield of arenes. © 2022 Society of Chemical Industry (SCI).
State of the field: A comparative analysis of international development studies majors in Canada, the United Kingdom and United States
Authors: Cohen Elisheva , Macekura Stephen 
Published: February 2022

AbstractThrough a critical analysis of undergraduate Development Studies (DS) majors, this study examines the ways that DS departments construct the discipline and contribute to the production of knowledge in the field. By comparing curricular requirements of DS majors at 56 universities, this paper illuminates priorities of DS as identified through teaching. We find that most DS majors have an interdisciplinary focus, require courses in economics and research methods and offer experiential learning opportunities. Limited attention, however, is given to regional or thematic specialisations and second language learning pointing to further work needed towards decolonizing DS curricula.

BackgroundDual‐venc 4D flow MRI, recently introduced for the assessment of intracranial hemodynamics, may provide a promising complementary approach to well‐established tools such as transcranial Doppler ultrasound (TCD) and overcome some of their disadvantages. However, data comparing intracranial flow measures from dual‐venc 4D flow MRI and TCD are lacking.PurposeTo compare cerebral blood flow velocity measures derived from dual‐venc 4D flow MRI and TCD.Study TypeProspective cohort.SubjectsA total of 25 healthy participants (56 ± 4 years old, 44% female).Field Strength/SequenceA 3 T/dual‐venc 4D flow MRI using a time‐resolved three‐dimensional phase‐contrast sequence with three‐dimensional velocity encoding.AssessmentPeak velocity measurements in bilateral middle cerebral arteries (MCA) were quantified from dual‐venc 4D flow MRI and TCD. The MRI data were quantified by two independent observers (S.M and Y.M.) and TCD was performed by a trained technician (A.L.M.). We assessed the agreement between 4D flow MRI and TCD measures, and the interobserver agreement of 4D flow MRI measurements.Statistical TestsPeak velocity from MRI and TCD was compared using Bland–Altman analysis and coefficient of variance. Intraclass correlation coefficient (ICC) was used to assess MRI interobserver agreement. A P value < 0.05 was considered statistically significant.ResultsThere was excellent interobserver agreement in dual‐venc 4D flow MRI‐based measurements of peak velocity in bilateral MCA (ICC = 0.97 and 0.96 for the left and right MCA, respectively). Dual‐venc 4D flow MRI significantly underestimated peak velocity in the left and right MCA compared to TCD (bias = 0.13 [0.59, −0.33] m/sec and 0.15 [0.47, −0.17] m/sec, respectively). The coefficient of variance between dual‐venc 4D flow MRI and TCD measurements was 26% for the left MCA and 22% for the right MCA.Data ConclusionThere was excellent interobserver agreement for the assessment of MCA peak velocity using dual‐venc 4D flow MRI, and ≤20% under‐estimation compared with TCD.Evidence Level3Technical EfficacyStage 2
