Published: December 2022

AbstractLoblolly pine (Pinus taeda L.) is the most widely planted forest tree species in the United States. Most of the seedlings used to establish these plantations come from seed collected in open-pollinated seed orchards, but an increasing number are coming from controlled crosses, about 15%–20% of the loblolly pine seedling crops in the last five years. To produce this seed, millions of pollination bags are installed each spring in orchards throughout the southeastern United States; over 2.6 million bags were installed in 2022. This study evaluated 13 pollination bag types available for use in the mass production of control-cross seed. Using cone analysis, significant differences were found among bag types for the proportion of ovules resulting in filled seed, empty seed, and first-year aborts. Due to differences in the efficacy of orchard management, study trees varied greatly in their proportion of ovules resulting in filled seed and first-year aborts. Under good orchard management, open-pollinated cones had 72% of their ovules as filled seed and 12% in first-year aborted ovules. The best pollination bag type had 62% of its ovules as filled seed with 22% in first-year aborted ovules. These differences are apparently due to the quality of pollen used in the controlled crosses.Study Implications: Compared with open-pollinated families, full-sibling crosses among elite parents of loblolly pine produce more market value to landowners due to greater productivity, increased disease resistance, and enhanced stem form. Specific crosses of loblolly pine have occupied about 15%–20% of the recent seedling market because the seed are costly and difficult to produce. This study tested pollination bag types to determine their effectiveness in producing control-cross seed. Some bag types were superior in increasing seed yield, but seed yields for open-pollinated cones tended to be higher, suggesting problems in the control-cross process. Cone analysis is a useful tool for seed orchard managers to diagnose problems in seed production. Understanding and correcting these problems will help managers increase their production of full-sibling seed and lead to the establishment of new plantations with increased forest productivity.
Mitotic progression and dual spindle formation caused by spindle association of de novo–formed microtubule-organizing centers in parthenogenetic embryos of Drosophila ananassae

Abstract
Facultative parthenogenesis occurs in many animal species that typically undergo sexual reproduction. In Drosophila, such development from unfertilized eggs involves diploidization after completion of meiosis, but the exact mechanism remains unclear. Here we used a laboratory stock of Drosophila ananassae that has been maintained parthenogenetically to cytologically examine the initial events of parthenogenesis. Specifically, we determined whether the requirements for centrosomes and diploidization that are essential for developmental success can be overcome. As a primal deviation from sexually reproducing (i.e. sexual) strains of the same species, free asters emerged from the de novo formation of centrosome-like structures in the cytosol of unfertilized eggs. Those microtubule-organizing centers had distinct roles in the earliest cycles of parthenogenetic embryos with respect to mitotic progression and arrangement of mitotic spindles. In the first cycle, an anastral bipolar spindle self-assembled around a haploid set of replicated chromosomes. Participation of at least one microtubule-organizing center in the spindle was necessary for mitotic progression into anaphase. In particular, the first mitosis involving a monastral bipolar spindle resulted in haploid daughter nuclei, one of which was associated with a microtubule-organizing center whereas the other was not. Remarkably, in the following cycle, biastral and anastral bipolar spindles formed that were frequently arranged in tandem by sharing an aster with bidirectional connections at their central poles. We propose that, for diploidization of haploid nuclei, unfertilized parthenogenetic embryos utilize dual spindles during the second mitosis, as occurs for the first mitosis in normal fertilized eggs.
Older Adults’ Experiences Living With and Having Spine Surgery for Degenerative Spine Disease
Authors: Strayer Andrea L , King Barbara J 
Published: December 2022

Abstract

Background and Objectives
Globally, older adults are undergoing spine surgery for degenerative spine disease at exponential rates. However, little is known about their experiences of living with and having surgery for this debilitating condition. This study investigated older adults’ understanding and experiences of living with and having surgery for degenerative spine disease.

Research Design and Methods
Qualitative methods, grounded theory, guided the study. Fourteen older adults (≥65 years) were recruited for in-depth interviews at 2 time-points: T1 during hospitalization and T2, 1–3-months postdischarge. A total of 28 interviews were conducted. Consistent with grounded theory, purposive, and theoretical sampling were used. Data analysis included open, axial, and selective coding.

Results
A conceptual model was developed illustrating the process older adults with degenerative spine disease experience, trying to get their life back. Three key categories were identified (1) Losing Me, (2) Fixing Me, and (3) Recovering Me. Losing Me was described as a prolonged process of losing functional independence and the ability to socialize. Fixing Me consisted of preparing for surgery and recovery. Recovering Me involved monitoring progression and reclaiming their personhood. Conditions, including setbacks and delays, slowed their trajectory. Throughout, participants continually adjusted expectations.

Discussion and Implications
The conceptual model, based on real patient experiences, details how older adults living with and having surgery for degenerative spine disease engage in recovering who they were prior to the onset of symptoms. Our findings provide a framework for understanding a complex, protracted trajectory that involves transitions from health to illness working toward health again.

Abstract
The mechanisms involved in HIV-associated natural killer (NK) cell impairment are still incompletely understood. We observed HIV infection to be associated with increased plasma levels of IFABP, a marker for gut epithelial barrier dysfunction, and LBP, a marker for microbial translocation. Both IFABP and LBP plasma concentrations were inversely correlated with NK cell interferon-γ production, suggesting microbial translocation to modulate NK cell functions. Accordingly, we found lipopolysaccharide to have an indirect inhibitory effect on NK cells via triggering monocytes’ transforming growth factor-β production. Taken together, our data suggest increased microbial translocation to be involved in HIV-associated NK cell dysfunction.

Published: December 2022

Abstract

Background
Whether pediatric rotavirus infection is associated with extraintestinal complications remains unknown.

Methods
We conducted a case-control study to investigate the incidences and risks of rotavirus-associated extraintestinal complications in hospitalized newborns, infants, and children younger than 5 years.

Results
A total of 1325 young inpatients with rotavirus infection (754 male and 539 newborns) and 1840 controls without rotavirus infection (1035 male and 836 newborns) were included. The incidences of neurological disease were higher among rotavirus individuals compared with controls: newborns, 7.24% (39/539) versus 2.87% (24/836), P &lt; .001; infants and young children, 19.59% (154/786) versus 12.35% (124/1004), P &lt; .001. The associated odd ratios (ORs) for neurological disease frequency following rotavirus infection was 2.64 (95% confidence interval [CI], 1.57–4.44) for newborns and 1.73 (95% CI, 1.34–2.24) for infants and young children, which increased to 2.56 (95% CI, 1.57–4.18) in case-control (1:1) matching analysis and 1.85 (95% CI, 1.41–2.42) in confounder adjustment. Rotavirus infection was associated with other extraintestinal complications, depending on study population and disease severity. Outcome analysis revealed rotavirus infection and its consequences had a significant impact on hospitalization and discharge.

Conclusions
Rotavirus exposure was associated with a spectrum of extraintestinal complications, particularly neurological disease. Rotavirus infection and subsequent consequences resulted in poor clinical outcomes.
The Fraught Notion of a “Good Death” in Pediatrics
Authors: Moore Bryanna 
Published: December 2022

AbstractIn this article, I sort through some of the confusion surrounding what constitutes the controversial notion of a “good death” for children. I distinguish, first, between metaphysical and practical disagreements about the notion of a good death, and, second, between accounts of a good death that minimally and maximally promote the dying child’s interests. I propose a narrowed account of the dying child’s interests, because they differ from the interests of non-dying children. Importantly, this account illustrates how disagreements at the end of a child’s life are sometimes the result of a shift from a future to a present-oriented understanding of the child’s interests on the part of some stakeholders but not others, and sometimes the result of a values-based disagreement about how different interests should be weighted. This brings into sharper focus the questions of for whom, and in what way, a child’s death might be considered good.
Inguinal bladder hernia: differentials for a male groin mass

Published: December 2022

Abstract
Inguinal bladder hernia (IBH) is an uncommon occurrence in males with a groin mass. It may be present with lower urinary tract symptoms but is often asymptomatic, making it a diagnostic challenge. IBH is frequently an incidental finding during surgery, which increases the risk of iatrogenic injury of the bladder. This report examines the case of a 77-year-old male who experienced a painful, reducible right-sided groin mass with acute urinary retention. Investigations conducted through computed tomography exhibited a right indirect inguinal hernia containing omental fat and a portion of the urinary bladder. The patient underwent a right open herniorrhaphy with mesh repair. This report presents a systematic approach to differential diagnoses for a male groin mass and its relationship to IBH.
Locating the Backstage of Victorian Religion: Spaces of Irish Catholicism
Authors: Roddy Sarah 
Published: December 2022

Abstract
This introduction to the ‘Spaces of Irish Catholicism’ Roundtable argues that applying the concept of ‘space’ to nineteenth-century Irish Catholicism has the potential to offer significant new insights to our understandings of Irish Catholicism and the lives of ordinary Irish Catholics, but also to Victorian Studies and religious history more generally. In particular, it contends that the nature of Irish Catholicism in the later nineteenth century was such that examining its many different spaces offers a valuable means of enacting Peter Andersson’s plea to uncover the ‘backstage’ of the Victorian period. In describing the eight diverse papers that comprise the Roundtable, the introduction argues that a previously identified dichotomy between the ‘poetics of space’ and the ‘politics of space’ within the religious realm may need to be rethought.
A search for missing radio sources at z ≳ 4 using Lyman dropouts

Published: December 2022

ABSTRACT
Using the Lyman Dropout technique, we identify 148 candidate radio sources at z ≳ 4–7 from the 887.5 MHz Australian Square Kilometre Array Pathfinder (ASKAP) observations of the GAMA23 field. About 112 radio sources are currently known beyond redshift z ∼ 4. However, simulations predict that hundreds of thousands of radio sources exist in that redshift range, many of which are probably in existing radio catalogues, but do not have measured redshifts, either because their optical emission is too faint or because of the lack of techniques that can identify candidate high-redshift radio sources (HzRSs). Our study addresses these issues using the Lyman Dropout search technique. This newly built sample probes radio luminosities that are 1–2 orders of magnitude fainter than known radio-active galactic nuclei (AGN) at similar redshifts, thanks to ASKAP’s sensitivity. We investigate the physical origin of radio emission in our sample using a set of diagnostics: (i) radio luminosity at 1.4 GHz, (ii) 1.4 GHz to 3.4 μm flux density ratio, (iii) Far-IR detection, (iv) WISE colour, and (v) SED modelling. The radio/IR analysis has shown that the majority of radio emission in the faint and bright end of our sample’s 887.5 MHz flux density distribution originates from AGN activity. Furthermore, ∼10 per cent of our sample are found to have a 250 μm detection, suggesting a composite system. This suggests that some high-z radio-AGNs are hosted by SB galaxies in contrast to low-z radio-AGNs, which are usually hosted by quiescent elliptical galaxies.

ABSTRACT
Gaia EDR3 data were used to identify potential members in the outskirts of three ultra-faint dwarf (UFD) galaxies: Coma Berenices (&gt;2Rh), Ursa Major I (∼4Rh), and Boötes I (∼4Rh), as well as a new member in the central region of Ursa Major I. These targets were observed with the Gemini GRACES spectrograph, which was used to determine precision radial velocities and metallicities that confirm their associations with the UFD galaxies. The spectra were also used to measure absorption lines for 10 elements (Na, Mg, K, Ca, Sc, Ti, Cr, Fe, Ni, and Ba), which confirm that the chemical abundances of the outermost stars are in good agreement with stars in the central regions. The abundance ratios and chemical patterns of the stars in Coma Berenices are consistent with contributions from SN Ia, which is unusual for its star formation history and in conflict with previous suggestions that this system evolved chemically from a single core collapse supernova event. The chemistries for all three galaxies are consistent with the outermost stars forming in the central regions, then moving to their current locations through tidal stripping and/or supernova feedback. In Boötes I, however, the lower metallicity and lack of strong carbon enrichment of its outermost stars could also be evidence of a dwarf galaxy merger.
New radio-loud QSOs at the end of the Re-ionization epoch

Published: December 2022

ABSTRACT
We present the selection of high-redshift (z ≳ 5.7) radio-loud (RL) quasi-stellar object (QSO) candidates from the combination of the radio Rapid ASKAP Continuum Survey (RACS; at 888 MHz) and the optical/near-infrared Dark Energy Survey (DES). In particular, we selected six candidates brighter than $S_{\rm 888\, MHz}\gt 1$ mJy beam−1 and mag(zDES) &lt; 21.3 using the dropout technique (in the i-band). From this sample, we were able to confirm the high-z nature (z ∼ 6.1) of two sources, which are now among the highest redshift RL QSOs currently known. Based on our Gemini-South/GMOS observations, neither object shows a prominent Ly α emission line. This suggests that both sources are likely to be weak emission-line QSOs hosting radio jets and would therefore further strengthen the potential increase of the fraction of weak emission-line QSOs recently found in the literature. However, further multiwavelength observations are needed to constrain the properties of these QSOs and of their relativistic jets. From the discovery of these two sources, we estimated the space density of RL QSOs in the redshift range 5.9 &lt; z &lt; 6.4 to be 0.13$^{+0.18}_{-0.09}$ and found it to be consistent with the expectations based on our current knowledge of the blazar population up to z ∼ 5.
Kinematic lensing with the Roman Space Telescope

Published: December 2022

ABSTRACT
Kinematic lensing (KL) is a new cosmological measurement technique that combines traditional weak lensing (WL) shape measurements of disc galaxies with their kinematic information. Using the Tully–Fisher relation, KL breaks the degeneracy between intrinsic and observed ellipticity and significantly reduces the impact of multiple systematics that are present in traditional WL. We explore the performance of KL given the instrument capabilities of the Roman Space Telescope, assuming overlap of the High Latitude Imaging Survey (HLIS) and the High Latitude Spectroscopy Survey (HLSS) over 2000 deg2. Our KL suitable galaxy sample has a number density of ngal = 4 arcmin−1 with an estimated shape noise level of σϵ = 0.035. We quantify the cosmological constraining power on Ωm–S8 and wp–wa by running simulated likelihood analyses that account for redshift and shear calibration uncertainties, intrinsic alignment, and baryonic feedback. Compared to a traditional WL survey, we find that KL significantly improves the constraining power on Ωm–S8 (FoMKL = 1.70FoMWL) and wp–wa (FoMKL = 3.65FoMWL). We also explore a ‘narrow tomography KL survey’ using 30 instead of the default 10 tomographic bins; however, we find no meaningful enhancement to the figure of merit even when assuming a significant time dependence in our fiducial dark energy input scenarios.

Abstract
Diiron vinyliminium complexes constitute a large family of organometallics displaying a promising anticancer potential. The complexes [Fe2Cp2(CO)(μ-CO){μ-η1:η3-C(R3)C(R4)CN(R1)(R2)}]CF3SO3 (2a-c, 4a-d) were synthesized, assessed for their behavior in aqueous solutions (D2O solubility, Log Pow, stability in D2O/Me2SO-d6 mixture at 37°C over 48 h) and investigated for their antiproliferative activity against A2780 and A2780cisR ovarian cancer cell lines and the nontumoral one Balb/3T3 clone A31. Cytotoxicity data collected for 50 vinyliminium complexes were correlated with the structural properties (i.e. the different R1–R4 substituents) using the partial least squares methodology. A clear positive correlation emerged between the octanol–water partition coefficient and the relative antiproliferative activity on ovarian cancer cell lines, both of which appear as uncorrelated to the cancer cell selectivity. However, the different effects played by the R1–R4 substituents allow tracing guidelines for the development of novel, more effective compounds. Based on these results, three additional complexes (4p-r) were designed, synthesized and biologically investigated, revealing their ability to hamper thioredoxin reductase enzyme and to induce cancer cell production of reactive oxygen species.

AbstractBackgroundLow back pain (LBP) and poor subjective sleep quality (SSQ) are major risk factors for presenteeism. However, no studies have investigated whether combined LBP and poor SSQ are associated with presenteeism.AimsWe aimed to examine whether a combination of LBP and poor SSQ is associated with presenteeism.MethodsThis cross-sectional study included 936 workers (median age, 38 years; men, 89%), with evaluated presenteeism using the work limitations questionnaire. We divided them into ‘no presenteeism’ and ‘presenteeism’ categories. The presence of LBP was defined as a numerical rating scale (NRS) score of ≥1 in current pain intensity. SSQ was assessed using a single question regarding whether the participants typically got enough sleep. We categorized the participants into four groups: (i) LBP + poor SSQ, (ii) non-LBP + poor SSQ, (iii) LBP + good SSQ and (iv) non-LBP + good SSQ. Logistic regression analysis was used to investigate the association between presenteeism and the presence of LBP and poor SSQ, adjusting for age, sex, work type, education, marital status, smoking status, body mass index and weekly working hours.ResultsThe data from 533 participants were used for analysis (median age, 38 years; men, 90%, response rate, 66%). Combined LBP and poor SSQ were significantly associated with presenteeism (non-LBP + poor SSQ: adjusted odds ratio = 0.56, 95% CI 0.32–0.96; LBP + good SSQ: 0.33, 0.20–0.56; non-LBP + good SSQ: 0.29, 0.18–0.48).ConclusionsEvaluating both LBP and SSQ may be beneficial in considering presenteeism.
Introduction
Authors: Frost-Arnold Karen 
Published: December 2022

Abstract
The introductory chapter details the epistemological frameworks to be used throughout the applied chapters of the book. These frameworks include feminist accounts of objectivity, veritistic systems-oriented social epistemology, epistemologies of ignorance, virtue epistemology, and epistemic injustice studies. The introduction explains the core concepts and commitments of each approach. Additionally, some of these theories might seem to be strange bedfellows to some epistemologists, so the author shows how they are compatible and provide a mutually supporting set of evaluative frameworks. This chapter argues for a social epistemology that values truth and objectivity, while recognizing that inequalities shape our collective ability to attain these goals.
