Summary: Temperature is thought to be a key factor influencing global species richness patterns. We investigate the link between temperature and diversification in the butterfly family Pieridae by combining next generation DNA sequences and published molecular data with fine-grained distribution data. We sampled nearly 600 pierid butterfly species to infer the most comprehensive molecular phylogeny of the family and curated a distribution dataset of more than 800,000 occurrences. We found strong evidence that species in environments with more stable daily temperatures or cooler maximum temperatures in the warm seasons have higher speciation rates. Furthermore, speciation and extinction rates decreased in tandem with global temperatures through geological time, resulting in a constant net diversification.

Summary Recent availability of biodiversity data resources has enabled an unprecedented ability to estimate phylogenetically based biodiversity metrics over broad scales. Such approaches elucidate ecological and evolutionary processes yielding a biota and help guide conservation efforts. However, the choice of appropriate phylogenetic resources and underlying input data uncertainties may affect interpretation. Here, we address how differences among phylogenetic source trees and levels of phylogenetic uncertainty affect these metrics and test existing hypotheses regarding geographic biodiversity patterns across the diverse vascular plant flora of Florida, US. Ecological niche models for 1,490 Florida species were combined with a “purpose-built” phylogenetic tree (phylogram and chronogram), as well as with trees derived from community resources (Phylomatic and Open Tree of Life). There were only modest differences in phylodiversity metrics given the phylogenetic source tree and taking into account the level of phylogenetic uncertainty; we identify similar areas of conservation interest across Florida regardless of the method used., Graphical Abstract, Highlights • Phylodiversity patterns of Florida show peaks of diversity in Northern peninsular areas • Different input trees and uncertainty had modest or little influence on phylodiversity • Chronogram or phylogram had a significant effect on the interpretation of phylodiversity • We highlight areas of high phylodiversity and how these results affect conservation, Spatial Phylogenetics; Plant Biology; Biogeography

As technology has become more ubiquitous, it is increasingly used in health education and communication applications. In this chapter, we provide a review on the use of social agents, namely embodied conversational agents and robotic agents, for health education and health communication for aging-in-place. Health education and health communication are two emerging research applications for social agents, with potential to help older adults in managing their health by (1) disseminating health information, and (2) connecting older adults with informal and formal caregivers. There are a number of challenges that impede the adoption of social agents, specifically security, privacy, technology acceptance, and implementation in the home. While there are barriers, there are also many future opportunities to utilize social agents within this context. Potential future advances in connected health, comprehensive health decision making, and connected communities are discussed.

The results of a series of experiments using fast-waves in the ion cyclotron frequency (ICF) range are presented. A 20 kW and a 100 kW transmitter is used to study fast-wave excitation, propagation and coupling in the 15–30 MHz frequency range under steady-state and pulsed operating conditions. In addition, a broadband amplifier is used in the 30–50 MHz frequency range to study propagation at higher harmonics of the ion-cyclotron frequency. An all-metal, Faraday-shielded water-cooled, 120° poloidal angle, loop antenna is used to launch fast-waves at the midplane of an EBT cavity. The present antenna is designed to operate at power levels up to 20 kW for steady-state operation and 100 kW for pulsed operation. Wave propagation and coupling experiments have been completed at frequencies from 15 to 50 MHz for the following conditions: EBT-0 (B max ~ 5.8 kG, F ECH = 10.6 GH z ), EBT-I (B max ~ 10 kG, f ECH = 10.6 GHz and 18 GHz) and EBT-Scale (B max ~ 14.3 kG, f ECH = 28 GHz). These experiments have been conducted using majority species, H + , and minority species H + in a majority plasma and under various combinations of ion cyclotron heating (ICH) and electron cyclotron heating (ECH) power levels. In general, the ICH power was less than 20 kW steady-state and 100 kW pulsed while the ECH power levels were approximately 30 kW @ 10.6 GHz, 60 kW @ 18 GHz and 50 to 200 kW @ 28 GHz. Wave coupling measurements were performed using rf voltage and loop probes at the antenna feedthroughs and Faraday-shield midpoint by measuring relative changes between no-load (plasma off) and full-load (plasma on) conditions. Wave propagation studies were conducted using 10 small Faraday-shielded loop antennas in various EBT cavities so that the toroidal extent of the wave propagation and phase shift could be measured. Efficient coupling (25–85%) and wave propagation were observed at frequencies above the second harmonic of the ion cyclotron frequency for single species hydrogen and for multi-species (deuterium/hydrogen) plasmas.

An analysis of fast wave propagation in a cylindrical magneto-plasma with periodic boundary conditions approximating those of the Elmo Bumpy Torus is presented. The analysis shows that for the m = −1 poloidal mode and for EBT-S parameters ( 4 × 10 12 cm -3 , B = 7-14 kG, and plasma radius 15 cm) alternating short and long wavelength modes occur as frequency is varied in the range 2 j < 8. This effect should have an important influence on wave coupling and absorption. Other results indicate good wave energy penetration for both EBT-S and EBT-P (Proof of Principle) conditions. Finally, a complete wave launching system for coupling ICRH power into EBT-S is described.

Science - Abstract
Summary: DNA double-strand break (DSB) repair is critical for cell survival and genome integrity. Upon recognition of DSBs, repair proteins are transiently upregulated to facilitate repair through homologous recombination (HR) or non-homologous end joining (NHEJ). We present evidence that PRMT5 cooperates with pICln to function as a master epigenetic activator of DNA damage response (DDR) genes involved in HR, NHEJ, and G2 arrest (including RAD51, BRCA1, and BRCA2) to upregulate gene expression upon DNA damage. Contrary to the predominant role of PRMT5 as an epigenetic repressor, our results demonstrate that PRMT5 and pICln can activate gene expression, potentially independent of PRMT5's obligate cofactor MEP50. Targeting PRMT5 or pICln hinders repair of DSBs in multiple cancer cell lines, and both PRMT5 and pICln expression positively correlates with DDR genes across 32 clinical cancer datasets. Thus, targeting PRMT5 or pICln may be explored in combination with radiation or chemotherapy for cancer treatment. : Molecular Genetics; Molecular Biology; Molecular Mechanism of Gene Regulation Subject Areas: Molecular Genetics, Molecular Biology, Molecular Mechanism of Gene Regulation

Medicine - Abstract
In 2009, the U.S. Food and Drug Administration banned the sale of flavored cigarettes (excluding menthol) in the U.S. However, the sale of flavored e-cigarettes (FE) and flavored hookah tobacco (FHT) is still legal. In this study (conducted in the US in the period from October 2018 to February 2019), we estimated the prevalence of use of FE and FHT across users' sociodemographic characteristics (e.g., age, sex, race/ethnicity) and identified the key characteristics of tobacco users associated with use of FE and FHT. We analyzed the 2014–2015 Tobacco Use Supplement to the Current Population Survey data for current e-cigarette (n = 3691) and hookah tobacco (n = 658) users. Among e-cigarette users, 65.5% used FE; and among hookah tobacco users, 87.3% used FHT. Among e-cigarette users, the prevalence of use of FE was significantly higher for 18–24 year-old than 45+ year-old adults; women than men; Southern than Northeastern residents; and never smokers of regular cigarettes than current smokers of regular cigarettes (all adjusted p's

The rate and pattern of glucose metabolism, basal lipolysis, and intracellular concentration of free fatty acids were determined in isolated epididymal fat cell preparations (mean volume 30-800 pl) from rats on the basis of fat cell number and in relation to the cell volume. The effects of increasing glucose concentrations in the medium and of insulin on the cellular metabolic activities were compared. Expanding fat cell volume correlated positively and significantly (P < 0.001) with the synthesis of glyceride glycerol from glucose (correlation coefficient, r = 0.919), with rates of basal lipolysis (r = 0.663), and with intracellular free fatty acid accumulation (r = 0.796); it correlated negatively and significantly with glucose conversion to glyceride fatty acids (r = -0.814, P < 0.01). The differences in patterns of glucose metabolism and basal lipolysis between small (400 pl) fat cells were not modified by insulin or by increments in glucose concentration. The results indicate that the reduced capacity of the large fat cells to respond to insulin cannot be attributed solely to a limited capacity of the cells to take up and metabolize increasing amounts of glucose. The acquired unresponsiveness of the large cells to insulin may result from an alteration in the mechanism of action of insulin and may be related to an intracellular metabolic derangement with increased basal lipolysis, free fatty acid accumulation, and accelerated glyceride synthesis resulting from the accumulation of triglyceride.

- Abstract
The COVID-19 pandemic has created a burden on healthcare systems and increased demand for mental healthcare at a time when in-person services are limited. Many programs offering dialectical behavior therapy (DBT) for complex clients have pivoted to telehealth in order to increase access to critical mental healthcare. There is, however, limited research on the provision of telehealth treatment for clients with complex psychopathology more broadly, or the telehealth implementation of DBT more specifically. The aim of this study was to examine the use of telehealth services and related clinician attitudes and experiences in the context of DBT. We examined the degree of telehealth platform adoption among DBT clinicians, as well as changes in stress and self-care strategies. A supplemental aim was to gather clinicians' recommendations for providing DBT via telehealth. Participants included N = 99 DBT practitioners (79.8% female; 20.2% male). Qualitative and quantitative methods were used for data analysis. Findings show that telehealth DBT has been widely adopted among DBT clinicians, and that clinicians' attitudes to telehealth DBT are cautiously optimistic. Participants described three main areas of stress associated with DBT via telehealth provision, as well as lost and novel self-care strategies., (Copyright © 2023 Association for Behavioral and Cognitive Therapies.

Objectives: We explored the potential impact of abortion bans in neighboring states on Michigan's abortion volume., Study Design: Using ArcGIS mapping software, we determined which counties in neighboring states had their closest out-of-state abortion clinic in Michigan. We estimated the change in abortions in Michigan occurring from neighboring states' residents, assuming complete bans in those states., Results: Complete bans in neighboring states could increase abortion volume in Michigan by approximately 5928 out-of-state patients annually (21% increase)., Conclusions: Complete bans in neighboring states may markedly increase abortions occurring in Michigan, which may strain Michigan facilities' capacity to provide abortion care., (Copyright © 2023 Elsevier Inc.

- Abstract
The COVID-19 pandemic has had a profound global impact, affecting people's physical and mental health, and their social and economic circumstances. Mitigation measures have disproportionately affected women. Studies have reported menstrual cycle and psychological disturbance associated with the pandemic. Pregnancy is a risk factor for severe COVID-19 disease. Reports have also demonstrated associations between COVID-19 infection, vaccination and Long COVID syndrome and reproductive health disturbance. However, studies are limited and there may be significant geographical variation. Also there is bias amongst published studies, and menstrual cycle data was not included in COVID-19 and vaccine trials. Longitudinal population based studies are required. In this review we discuss existing data, along with recommendations for further research required in this area. We also discuss a pragmatic approach to women presenting with reproductive health disturbance in the era of the pandemic, encompassing a multi-system assessment of psychological, reproductive health and lifestyle., Competing Interests: Conflict of interest statement The authors do not have any conflicts of interest to declare., (Copyright © 2023 Elsevier Ltd.

- Abstract
In the United States, about 1 in 5 women have experienced childhood sexual abuse, and a similar proportion experience rape as adults. Childhood sexual abuse and other forms of trauma have serious impacts on our patients' reproductive health. The American College of Obstetricians and Gynecologists recommends universal screening for a history of sexual abuse and universal application of a trauma-informed approach to care. Despite these recommendations, universal screening is far from universally practiced, and trauma-informed care, despite being the standard of care, is far from standard. Given the high prevalence of trauma in the United States, its impact on perinatal outcomes, the sensitive nature of reproductive healthcare, and the likelihood that many patients may not disclose their trauma history, we advocate for trauma-informed reproductive healthcare as the standard of care., (Copyright © 2021 Elsevier Inc.

- Abstract
Introduction: In adults with bronchiectasis, multicentre data advanced the field including disease characterisation and derivation of phenotypes such as 'frequent exacerbator (FE)' (≥3 exacerbations/year). However, paediatric cohorts are largely limited to single centres and no scientifically derived phenotypes of paediatric bronchiectasis yet exists. Using paediatric data from the Australian Bronchiectasis Registry (ABR), we aimed to: (a) describe the clinical characteristics and compare Indigenous with non-Indigenous children, and (b) determine if a FE phenotype can be identified and if so, its associated factors., Methods: We retrieved data of children (aged <18-years) with radiologically confirmed bronchiectasis, enrolled between March 2016-March 2020., Results: Across five sites, 540 children [288 Indigenous; median age = 8-years (IQR 6-11)] were included. Baseline characteristics revealed past infection/idiopathic was the commonest (70%) underlying aetiology, most had cylindrical bronchiectasis and normal spirometry. Indigenous children (vs. non-Indigenous) had significantly more environmental tobacco smoke exposure (84% vs 32%, p < 0.0001) and lower birth weight (2797 g vs 3260 g, p < 0.0001). FE phenotype present in 162 (30%) children, was associated with being younger (OR
adjusted = 0.85, 95%CI 0.81-0.90), more recent diagnosis of bronchiectasis (ORadjusted = 0.67; 95%CI 0.60-0.75), recent hospitalization (ORadj = 4.51; 95%CI 2.45-8.54) and Pseudomonas aeruginosa (PsA) infection (ORadjusted = 2.43; 95%CI 1.01-5.78). The FE phenotype were less likely to be Indigenous (ORadjusted = 0.14; 95%CI 0.03-0.65)., Conclusion: Even within a single country, the characteristics of children with bronchiectasis differ among cohorts. A paediatric FE phenotype exists and is characterised by being younger with a more recent diagnosis, PsA infection and previous hospitalization. Prospective data to consolidate our findings characterising childhood bronchiectasis phenotypes are required., (Copyright © 2021. Published by Elsevier Ltd.)- Published

- Abstract
The health implications of urban development, particularly in rapidly changing, low-income urban neighborhoods, are poorly understood. We describe the Healthy Neighborhoods Study (HNS), a Participatory Action Research study examining the relationship between neighborhood change and population health in nine Massachusetts neighborhoods. Baseline data from the HNS survey show that social factors, specifically income insecurity, food insecurity, social support, experiencing discrimination, expecting to move, connectedness to the neighborhood, and local housing construction that participants believed would improve their lives, identified by a network of 45 Resident Researchers exhibited robust associations with self-rated and mental health. Resident-derived insights into relationships between neighborhoods and health may provide a powerful mechanism for residents to drive change in their communities., (Copyright © 2018 The Authors.

- Abstract
Objectives: To compare antiretroviral adherence (measured as the proportion of days covered [PDC]) and change in viral load in insured, HIV-infected, adult outpatients enrolled and not enrolled in a medication synchronization program., Methods: This was a multicenter, retrospective, pilot cohort study. Fifty-eight insured, HIV-infected, outpatients at least 18 years of age receiving antiretroviral therapy (ART) for at least 3 months as of August 2015 were included. PDC, viral load, PDC dichotomized into adherent or nonadherent, and viral load dichotomized into detectable or undetectable were collected for each patient. Study data were compared in those with (enrolled) and without (not enrolled or control) medication synchronization. The study end points were analyzed between the 2 groups retrospectively after 3 months., Results: PDC in patients undergoing medication synchronization was significantly higher than in control patients: mean ± SD 96 ± 9% versus 71 ± 27%, respectively (P < 0.0001). The medication synchronization group was also more likely to be adherent to ART than the control group (odds ratio 10.67, 95% confidence interval 2.63-43.31). In the medication synchronization group, 75.9% of patients had an undetectable baseline viral load, and 83.3% had an undetectable viral load at study completion. In the control group, 62.1% and 64.7% had an undetectable viral load at baseline and completion, respectively. No statistically significant change in viral load was observed between groups (P = 0.34)., Conclusion: In insured, HIV-infected, adult outpatients, implementation of a medication synchronization program was associated with improved ART adherence. Future studies are needed to better assess the impact of medication synchronization on clinical outcomes., (Copyright © 2018 American Pharmacists Association®. All rights reserved.)

- Abstract
The popularity of baclofen as an anti-craving agent in the treatment of alcohol use disorders (AUDs) has increased, especially in patients with established liver disease. However, evidence-based guidelines to inform practice are lacking. The aim of this systematic review is explore the prescribing practices of baclofen in AUD treatment. Electronic databases were searched for relevant articles from 2002. Assessment of eligibility criteria for inclusion was performed independently by two investigators. The main outcomes of interest were maximum dose, starting dose, titration regimen, effectiveness, and tolerability. Twenty-five studies reporting outcomes in 613 patients treated with baclofen for an AUD were identified. Starting doses ranged between 5 and 50mg/d. Titration was study-dependent, and doses were increased until either therapeutic target (abstinence or study-defined low risk drinking) was achieved or adverse events resulted in a dose reduction or discontinuation. The maximum dose for individual patients ranged between 20 and 630mg/d. Seven studies reported at least one patient using >300mg/d. In studies with 10 or more patients, we found a negative correlation between dose and proportion of patients achieving the therapeutic goal. However, this was skewed by one study. A range of serious adverse events were reported. Most were reported at doses over 100mg/d, but others presented at lower doses. Baclofen is a promising therapeutic in this area. Evidence is required, however, to support practitioners in prescribing doses that optimise outcomes and reduce adverse events., (Copyright © 2017 Elsevier B.V. and ECNP. All rights reserved.)

- Abstract
This study investigated Enterobacteriales and their antimicrobial resistance in green sea turtles captured adjacent to the central Great Barrier Reef (GBR) and proximate to urban development. Cloacal swabs were taken from 73 green turtles between 2015 and 2016. A total of 154 out of 341 Gram-negative bacterial isolates were identified as Enterobacteriales that represent 16 different species from 9 different genera. The dominant isolates were Citrobacter (30.52%), Edwardsiella (21.43%) and Escherichia (12.34%). The resistance against 12 antibiotics belonging to 6 different classes was determined. The isolates showed highest resistance to β-lactam antibiotics (78.57%) followed by quinolone (50%) and tetracycline classes (46.1%). Approximately one-third (37.7%) of the isolates identified exhibited multidrug-resistance. Isolates recovered from rehabilitated turtles were significantly multidrug resistant (p<0.009) compared to isolates from other study sites. These results provide baseline information on antimicrobial resistance while revealing gaps for further research to evaluate the level of pollution in the GBR., (Copyright © 2017 Elsevier Ltd.

- Abstract
In 1999, the causative agent of an epizootic in Cherax quadricarinatus was described, and given the provisional name Cherax quadricarinatus parvovirus-like. Sequencing of the 6334 nt genome identified three open-reading frames on the top strand coding NS3 (35.55 kDa), NS1 (67.36 kDa) and NS2 (35.18 kDa) and on the bottom strand a single open reading frame which most likely encodes 4 structural proteins. Motifs characteristic of the Densovirinae were found in the ORFs. Phylogenetic analysis of the amino acids in NS1 places the genome in the genus Ambidensovirus, most closely related to the marine sea star densovirus (75%, E=0.0) and distantly related to Acheta domestica densovirus (44.1%). The virus name is proposed as species Decapod ambidensovirus, variant Cherax quadricarinatus densovirus. This is the first Ambidensovirus to be found in decapod crustaceans and the first of the subfamily Densovirinae to be sequenced from a freshwater crayfish. Cherax quadricarinatus densovirus and sea star densovirus are the first highly related Densovirinae to infect phylogenetically disparate hosts and are thus far, unique among the Densovirinae., (Copyright © 2015 Elsevier B.V.

- Abstract
Nuclear location sequences (NLSs) link proteins to importation molecules for transportation into the nucleus. A bioinformatical search of the penaeid parvoviruses was undertaken to look for NLS. All three ORFs of Penaeus merguiensis densovirus (PmergDNV) have functional NLS whilst only the two non-structural proteins of Penaeus stylirostris densovirus (PstDNV) appear to. In PmergDNV, NS1 has a NLS similar to DNA helicase Q1, NS2 is similar to Dorsal and VP1 is similar to SV40 T-antigen signal. In PstDNV, NS2 has a NLS that is an unrecognised pattern unless it is a monopartite Chelsky signal whilst NS1 has both a Dorsal and minute virus of mouse signals. The capsid protein NLS of PstDNV is likely to be inefficient. Spawner isolated mortality virus has a NLS like DNA helicase Q1. These NLSs affect the nature of inclusion bodies seen with light microscopy, basophilic in PmergDNV; eosinophilic in PstDNV and the site of encapsidation, nuclear in PmergDNV; cytoplasmic in PstDNV as seen with TEM. Many possible NLSs in penaeid parvoviruses are homologues to those in eukaryotic organisms and need to be tested experimentally., (© 2013.)

- Abstract
The implantation of medical devices often triggers several immune responses, one kind of which is categorized as foreign body reactions. It is well established that macrophages and many other cells participate in the complex processes of foreign body reactions, and cause severe inflammations and fibrotic capsule formation in surrounding tissues. However, the detailed mechanisms of macrophage responses, recruitment and activation, in foreign body reactions are not totally understood. In the meantime, mathematical models have been proposed to systematically decipher the behavior of this complex system of multiple cells, proteins and biochemical processes in wound healing responses. Based on these early works, this study introduces a mathematical model in two spatial dimensions to investigate the transient behavior of macrophages, fibroblasts and their interactions during the formation of fibrotic tissue. We find that the simulation results are consistent with the experimental observations. These findings support that the model can reveal quantitative insights for studying foreign body reaction processes., (© 2013. Published by Elsevier B.V. All rights reserved.)

- Abstract
Gestational diabetes mellitus (GDM) is defined as any degree of glucose intolerance with onset or first recognition during pregnancy and is associated with a range of maternal and neonatal complications and conditions. Given increasing levels of prevalence worldwide, there are growing calls for the implementation of screening practices to identify and treat positive GDM cases. This paper uses a unique dataset to investigate the role of healthcare centre accessibility on the decision to attend for screening, employing geographic information systems, econometric and simulation techniques. We focus on the extent to which 'travel distance to screening hospital site' impacts upon the individual's screen uptake decision, whether significant geographic inequalities exist in relation to accessibility to screening, and the likely impact on uptake rates of providing screening services at a local level via primary care. Our findings have important implications for the provision of GDM screening services., (Copyright © 2011 Elsevier Ltd. All rights reserved.)

- Abstract
Providing small enteral feedings for parenterally fed preterm infants during the first few weeks of life improves feeding tolerance. However, it is not known whether these feedings achieve this result via stimulation of gut growth and/or maturation of function. The minimal level needed to attain these responses is also critical to identify, because neonatologists often limit feeding volumes to minimize the risk of necrotizing enterocolitis. Thus, we determined the dose-response relationships between enteral feeding volume and gastrointestinal growth and small intestine motor function. Newborn canine pups (n = 51) received 0, 2.5, 5.0, 7.5, 10, 30 or 100% of their daily fluid intake enterally with the remainder given parenterally for 4-5 d. Motor activity was recorded, blood drawn for determination of gastrin and motilin, and intestinal tissue harvested for determination of DNA and protein content and morphology. Feeding volumes that provided 30% or more of daily fluid intake significantly increased small intestinal mucosal growth above that of unfed pups, but feeding volumes that provided as little as 10% of daily fluid intake significantly induced maturation of motor patterns beyond that of unfed pups. Plasma concentrations of gastrin and motilin did not differ among groups. We conclude that small enteral feedings typically used for minimal enteral feeding strategies improve feeding tolerance by triggering maturation of motor function but not gut growth in neonatal dogs. Small feeding volumes trigger this maturation as well as large volumes.

- Abstract
Prevention of myocardial acidosis during global ischemia in operative cardiopreservation was explored in two series of dogs where acid-base control was the only variable. A specifically designed aminosulfonic acid buffer composition, 3:1 molar equivalents NaMOPS to HEPES, 0.2 mol/L, was compared with NaHCO3 (pH 8). Dissolved in standard cardioplegic solution it was given every 30 minutes by coronary infusion at 20 degrees C during 3 hours of global ischemia. Glass electrode intramyocardial pH, adenosine triphosphate (ATP) level, left ventricular contractility (Dp/Dt) and compliance (-Dp/Dt), and other cardiovascular parameters were measured frequently throughout ischemia and for 75 minutes thereafter. In the buffer group (n = 6) myocardial pH remained above entry levels throughout the study period, adenosine triphosphate level remained normal during ischemia, and Dp/Dt and -Dp/Dt at 75 minutes of reperfusion were above entry levels. In the NaHCO3 group (n = 6) pH declined and remained depressed throughout ischemia, adenosine triphosphate level fell steadily and significantly throughout the experiment, and Dp/Dt and -Dp/Dt never regained entry levels. The difference in each parameter between the two groups was statistically significant (p < 0.05). We conclude that control of myocardial acid-base equilibrium alone during global ischemia will preserve myocardial function and minimize reperfusion injury.
