Published: July 2023

Context Free-roaming dogs are ubiquitous worldwide and pose a threat to wildlife. An understanding of the roaming behaviour of dogs is useful for developing effective management strategies. Aims We aimed to assess the activity ranges and patterns of free-roaming dogs in a rural Cambodian village. An adjacent wildlife sanctuary protects populations of threatened species that may be negatively impacted by dogs. Methods We used rudimentary hand-made GPS collars to track village dogs and quantify their movements. Activity ranges were calculated for male and female dogs, and the mean distances travelled at night and during the day were determined. Additionally, forays outside of the activity range were characterised. Key results We estimated a mean activity range of 178 ± 190 ha and found that dogs typically travelled longer distances at night. Females had significantly smaller activity ranges, as well as covering shorter distances per day. Foray behaviour was variable, with some dogs entering the wildlife sanctuary regularly and others not at all. Conclusions Free-roaming Cambodian dog activity overlapped with native mammals in the study site, posing a risk of predation, resource exclusion, harassment and competition of Cambodian species. Implications The data suggest that although dogs generally spend the majority of their time within the village, there is significant risk to wildlife. Actions are required to mitigate threats to native wildlife, in particular threatened species such as Eld’s Deer.

AbstractTo reduce the use of chemical fertilizers and maximize agricultural yields, the use of microalgae extracts as biostimulants has recently attracted significant attention due to their favourable impact on both plant growth and their ability to induce tolerance towards environmental stressors. Lettuce (Lactuca sativa) is one of the most important fresh vegetables that often requires applications of chemical fertilizers to increase quality and productivity. Accordingly, the purpose of this study was to analyse the transcriptome reprogramming of lettuce (L. sativa) seedlings in response to either Chlorella vulgaris or Scenedesmus quadricauda extracts by applying an RNAseq approach. Differential gene expression analysis revealed that the core gene set that responded to microalgal treatments in a species-independent manner includes 1330 clusters, 1184 of which were down-regulated and 146 up-regulated, clearly suggesting that the repression of gene expression is the main effect of algal treatments. The deregulation of 7197 transcripts in the C. vulgaris treated seedlings compared to control samples (LsCv vs. LsCK) and 7118 transcripts in the S. quadricauda treated seedlings compared to control samples (LsSq vs. LsCK) were counted. Although the number of deregulated genes turned out to be similar between the algal treatments, the level of deregulation was higher in LsCv versus LsCK than in LsSq versus LsCK. In addition, 2439 deregulated transcripts were observed in the C. vulgaris treated seedlings compared to S. quadricauda treated samples (LsCv vs. LsSq comparison) suggesting that a specific transcriptomic profile was induced by the single algal extracts. ‘Plant hormone signal transduction’ category includes a very elevated number of DEGs, many of them specifically indicating that C. vulgaris actives both genes involved in the auxin biosynthesis and transduction pathways, whereas S. quadricauda up-regulates genes implicated in the cytokinin biosynthesis pathway. Finally, algal treatments induced the deregulation of genes encoding small hormone-like molecules that are known to act alone or by interacting with major plant hormones. In conclusion, this study offers the groundwork to draw up a list of putative gene targets with the aim of lettuce genetic improvement that will allow a limited or even null use of synthetic fertilizers and pesticides in the management of this crop.

Abstract

Glucagon-like peptide 1 (GLP-1) agonists are a drug class used for the treatment of diabetes that have recently gained FDA approval for medical management of obesity. The off-label use of Ozempic (Novo Nordisk, Bagsværd, Denmark), the brand name of the GLP-1 agonist semaglutide, for cosmetic weight loss has been popularized by social media and celebrity influence. The aim of this study was to analyze with Google Trends (Alphabet Inc., Mountain View, CA) the recent search popularity of Ozempic and related GLP-1 agonists. The term “Ozempic” was analyzed with Google Trends. Search popularity was assessed in terms of relative search volume (RSV) over a 5-year period. Changes in RSV were further compared with other GLP-1 agonists, “Wegovy” (Novo NordisK) and “Mounjaro” (Eli Lilly and Company, Indianapolis, IN). Between March 2018 and February 2023, overall RSV in “Ozempic” grew exponentially in the United States. Simple linear regression analysis showed significantly increased RSV over time with an R2 of 0.915 and a regression coefficient of 0.957 (P &lt; .001). When comparing “Ozempic,” “Wegovy,” and “Mounjaro” since June 2021 (FDA approval of Wegovy), Ozempic remained at the greatest RSV. One-way analysis of variance found statistically significant differences between the 3 search terms at all time points between December 2021 and February 2023 (P &lt; .001). This study demonstrates a significant and growing public interest in Ozempic and related GLP-1 agonists. As the use of GLP-1 agonists for weight loss becomes more prevalent, plastic surgeons, particularly in the aesthetic setting, must be prepared for the downstream implications. Increased awareness, understanding, and further scientific studies led by plastic surgeons will help deliver the safest possible patient outcomes.

Morphological and anatomical evolution of species of Valeriana (Caprifoliaceae) during the uplift of the Andean range
Authors: Cruz Rafael , Klimeš Adam , Doležal Jiří , Sklenář Petr , Klimešová Jitka 
Published: July 2023

Abstract
Andean species of Valeriana are frequently pointed to as an example of island woodiness, i.e. plants with herbaceous ancestors that usually evolve woodier forms on islands. We investigated this phenomenon through morphoanatomical and phylogenetic analyses. Plants were collected in the Páramos of Ecuador and had their vegetative morphology described. Stems were sectioned for histological analyses. We mapped the morphoanatomical data plus the maximum reported size for these and other species of the genus, on phylogenetic trees reconstructed on the basis of previously published sequences. Bigger than their Holarctic counterparts, the ancestor of the South American Valeriana was likely to have had a maximum size of 132 cm, and then after evolved to bigger and smaller sizes in a pattern similar to Brownian motion, as supported by phylogenetic signal values. We classified the collected plants into six growth forms (rosette herbs, semirosette herbs, elevated rosettes, elevated semirosettes, shrubs, and lianas), that are not directly related to variable levels of woodiness, as pointed out by our histological analyses. However, the production of unlignified parenchyma in the wood is very frequent, except in older regions of shrubs. The ancestor of the South American Valeriana is also very likely to have unlignified parenchyma in its wood.

Published: July 2023

Abstract
Floral traits are used as signals to attract pollinators and play an important role in species identification and isolation. Nicotiana is a genus with a diverse range of flower morphologies, colours, and pollination systems related to a natural history of hybridization, a driver of speciation in this genus. Nicotiana alata and Nicotiana forgetiana are pollinated by hawkmoths and hummingbirds, respectively, and a putative hybrid population was recently found. This population presents flowers with intermediate phenotypes providing an opportunity to investigate the impact of hybridization on floral trait variation. Here we investigated the floral shape, floral pigments, and nectar traits in a putative hybrid population, hereafter termed atypical populations (AP) compared to phenotypes of allopatric populations of both species. We found a high variation in floral pigmentation in AP plants and observed phenotype segregation in some genotypes. Nicotiana forgetiana and AP plants showed the same flavanol peaks as Nicotiana alata, suggesting the same UV-absorbent phenotype attractive to hawkmoths. The geometric morphometric results showed that the intermediate-coloured flowers had similar floral shape and size to N. alata. Our results suggest that the putative hybrid population would be able to attract the same parental pollinator—hawkmoths and hummingbirds—making backcrossing events possible and attracting other pollinators, such as bees.
Heritability and preadult survivorship costs of ectoparasite resistance in the naturally occurring Drosophila–Gamasodes mite system

Published: July 2023

Abstract
Our understanding of the evolutionary significance of ectoparasites in natural communities is limited by a paucity of information concerning the mechanisms and heritability of resistance to this ubiquitous group of organisms. Here, we report the results of artificial selection for increasing ectoparasite resistance in replicate lines of Drosophila melanogaster derived from a field-fresh population. Resistance, as ability to avoid infestation by naturally co-occurring Gamasodes queenslandicus mites, increased significantly in response to selection and realized heritability (SE) was estimated to be 0.11 (0.0090). Deployment of energetically expensive bursts of flight from the substrate was a main mechanism of host resistance that responded to selection, aligning with previously documented metabolic costs of fly behavioral defenses. Host body size, which affects parasitism rate in some fly–mite systems, was not shifted by selection. In contrast, resistant lines expressed significant reductions in larva-to-adult survivorship with increasing toxic (ammonia) stress, identifying an environmentally modulated preadult cost of resistance. Flies selected for resistance to G. queenslandicus were also more resistant to a different mite, Macrocheles subbadius, suggesting that we documented genetic variation and a pleiotropic cost of broad-spectrum behavioral immunity against ectoparasites. The results demonstrate significant evolutionary potential of resistance to an ecologically important class of parasites.
When the neighborhood matters: contextual selection on seedling traits in native and non-native California grasses
Authors: Waterton Joseph , Mazer Susan J , Cleland Elsa E 
Published: July 2023

AbstractPlants interact extensively with their neighbors, but the evolutionary consequences of variation in neighbor identity are not well understood. Seedling traits are likely to experience selection that depends on the identity of neighbors because they influence competitive outcomes. To explore this, we evaluated selection on seed mass and emergence time in two California grasses, the native perennial Stipa pulchra, and the non-native annual Bromus diandrus, in the field with six other native and non-native neighbor grasses in single- and mixed-species treatments. We also quantified characteristics of each neighbor treatment to further investigate factors influencing their effects on fitness and phenotypic selection. Selection favored larger seeds in both focal species and this was largely independent of neighbor identity. Selection generally favored earlier emergence in both focal species, but neighbor identity influenced the strength and direction of selection on emergence time in S. pulchra, but not B. diandrus. Greater light interception, higher soil moisture, and greater productivity of neighbors were associated with more intense selection for earlier emergence and larger seeds. Our findings suggest that changes in plant community composition can alter patterns of selection in seedling traits, and that these effects can be associated with measurable characteristics of the community.

Abstract

Background
Frailty is increasingly recognized as a useful measure of vulnerability in older adults. Multiple claims-based frailty indices (CFIs) can readily identify individuals with frailty, but whether 1 CFI improves prediction over another is unknown. We sought to assess the ability of 5 distinct CFIs to predict long-term institutionalization (LTI) and mortality in older Veterans.

Methods
Retrospective study conducted in U.S. Veterans ≥65 years without prior LTI or hospice use in 2014. Five CFIs were compared: Kim, Orkaby (Veteran Affairs Frailty Index [VAFI]), Segal, Figueroa, and the JEN-FI, grounded in different theories of frailty: Rockwood cumulative deficit (Kim and VAFI), Fried physical phenotype (Segal), or expert opinion (Figueroa and JFI). The prevalence of frailty according to each CFI was compared. CFI performance for the coprimary outcomes of any LTI or mortality from 2015 to 2017 was examined. Because Segal and Kim include age, sex, or prior utilization, these variables were added to regression models to compare all 5 CFIs. Logistic regression was used to calculate model discrimination and calibration for both outcomes.

Results
A total of 3 million Veterans were included (mean age 75, 98% male participants, 80% White, and 9% Black). Frailty was identified for between 6.8% and 25.7% of the cohort with 2.6% identified as frail by all 5 CFIs. There was no meaningful difference between CFIs in the area under the receiver operating characteristic curve for LTI (0.78–0.80) or mortality (0.77–0.79).

Conclusions
Based on different frailty constructs, and identifying different subsets of the population, all 5 CFIs similarly predicted LTI or death, suggesting each could be used for prediction or analytics.

Abstract
Type B lactic acidosis is a rare complication of gastric adenocarcinoma and is associated with poor prognosis. Very few cases have been reported in the literature. A 48-year-old female presented with recurrent episodes of vomiting, loss of appetite and loss of weight for 1 month duration. Endoscopy and subsequent biopsy revealed poorly differentiated adenocarcinoma at the pyloric antrum causing gastric outflow obstruction. Contrast enhanced computed tomography scan of the chest, abdomen and pelvis revealed a malignant neoplasm of the pylorus with no distant metastasis. She developed refractory lactic acidosis not responding to medical treatment. Distal gastrectomy with limited lymph node clearance was done and lactic acidosis improved. Pathophysiology of type B lactic acidosis in solid organ malignancies can be due to the rapid turnover of cells inducing anaerobic glycolysis, thiamine deficiency and extensive hepatic metastasis. This patient did not have hepatic metastasis. This is a successful, surgically managed case of type B lactic acidosis in a patient with gastric adenocarcinoma so far reported in the region. Type B lactic acidosis is very rare in gastric cancer. Patients with refractory lactic acidosis should bring about high suspicion of solid organ malignancies and good clinical outcomes can be obtained by the reduction of tumour burden.
BRUTUS-LIKE (BTSL) E3 ligase-mediated fine-tuning of Fe regulation negatively affects Zn tolerance of Arabidopsis
Authors: Stanton Camilla , Rodríguez-Celma Jorge , Krämer Ute , Sanders Dale , Balk Janneke 
Published: July 2023

Abstract
The mineral micronutrients zinc (Zn) and iron (Fe) are essential for plant growth and human nutrition, but interactions between the homeostatic networks of these two elements are not fully understood. Here we show that loss of function of BTSL1 and BTSL2, which encode partially redundant E3 ubiquitin ligases that negatively regulate Fe uptake, confers tolerance to Zn excess in Arabidopsis thaliana. Double btsl1 btsl2 mutant seedlings grown on high Zn medium accumulated similar amounts of Zn in roots and shoots to the wild type, but suppressed the accumulation of excess Fe in roots. RNA-sequencing analysis showed that roots of mutant seedlings had relatively higher expression of genes involved in Fe uptake (IRT1, FRO2, and NAS) and in Zn storage (MTP3 and ZIF1). Surprisingly, mutant shoots did not show the transcriptional Fe deficiency response which is normally induced by Zn excess. Split-root experiments suggested that within roots the BTSL proteins act locally and downstream of systemic Fe deficiency signals. Together, our data show that constitutive low-level induction of the Fe deficiency response protects btsl1 btsl2 mutants from Zn toxicity. We propose that BTSL protein function is disadvantageous in situations of external Zn and Fe imbalances, and formulate a general model for Zn–Fe interactions in plants.
Determinants and changes in adherence to the World Cancer Research Fund/American Institute for Cancer Research cancer-prevention recommendations over the past 25 years in Switzerland
Authors: Suter Flurina , Karavasiloglou Nena , Hämmig Oliver , Rohrmann Sabine , Pestoni Giulia 
Published: July 2023

Objectives
The World Cancer Research Fund (WCRF) and the American Institute for Cancer Research (AICR) established 10 lifestyle recommendations for cancer prevention. The current study examines the proportion and changes over 25 years of adherence to these recommendations and their determinants in Switzerland.

Methods
On the basis of six Swiss Health Surveys (1992–2017, N = 110 478), an index reflecting adherence to the 2018 WCRF/AICR cancer-prevention recommendations was created. Multinomial logistic regression models were fitted to investigate changes over time and determinants of a cancer-protective lifestyle.

Results
Adherence to cancer-prevention recommendations was moderate and higher in the years 1997–2017 compared to 1992. Higher adherence was observed among women (odds ratio [OR]high vs. low adherence ranging from 3.31 to 3.74) and participants with a tertiary education level (ORhigh vs. low adherence ranging from 1.71 to 2.18), and lower adherence among participants of the oldest age group (ORhigh vs. low adherence ranging from 0.28 to 0.44) and participants of the Switzerland (lat.: Confoederatio helvetica)-French language regions (ORhigh vs. low adherence ranging from 0.53 to 0.73).

Conclusion
Our results showed that cancer-prevention recommendations are not well followed by the general Swiss population, as the adherence to a cancer-protective lifestyle was generally moderate; however, adherence to cancer-prevention recommendations improved over the past 25 years. Sex, age group, education level, and language regions were significant determinants of adherence to a cancer-protective lifestyle. Further actions at the governmental and individual levels promoting the adoption of a cancer-protective lifestyle are needed.
Self-consistent and detailed opacities from a non-equilibrium average-atom model
Authors: Hansen S. B. 
Published: July 2023

Modern density functional theory (DFT) is a powerful tool for accurately predicting self-consistent material properties such as equations of state, transport coefficients and opacities in high energy density plasmas, but it is generally restricted to conditions of local thermodynamic equilibrium (LTE) and produces only averaged electronic states instead of detailed configurations. We propose a simple modification to the bound-state occupation factor of a DFT-based average-atom model that captures essential non-LTE effects in plasmas—including autoionization and dielectronic recombination—thus extending DFT-based models to new regimes. We then expand the self-consistent electronic orbitals of the non-LTE DFT-AA model to generate multi-configuration electronic structure and detailed opacity spectra.

Published: July 2023

In this review, we describe the application of Boltzmann kinetic equations for modelling warm dense matter and plasma formed after irradiation of solid materials with intense femtosecond X-ray pulses. Classical Boltzmann kinetic equations are derived from the reduced N-particle Liouville equations. They include only single-particle densities of ions and free electrons present in the sample. The first version of the Boltzmann kinetic equation solver was completed in 2006. It could model non-equilibrium evolution of X-ray-irradiated finite-size atomic systems. In 2016, the code was adapted to study plasma created from X-ray-irradiated materials. Additional extension of the code was then also performed, enabling simulations in the hard X-ray irradiation regime. In order to avoid treatment of a very high number of active atomic configurations involved in the excitation and relaxation of X-ray-irradiated materials, an approach called ‘predominant excitation and relaxation path’ (PERP) was introduced. It limited the number of active atomic configurations by following the sample evolution only along most PERPs. The performance of the Boltzmann code is illustrated in the examples of X-ray-heated solid carbon and gold. Actual model limitations and further model developments are discussed.
