Ocean acidification alters foraging behaviour in Dungeness crab through impairment of the olfactory pathway
Authors: Durant Andrea , Khodikian Elissa , Porteus Cosima S. 
Published: May 2023

AbstractCrustacean olfaction is fundamental to most aspects of living and communicating in aquatic environments and more broadly, for individual‐ and population‐level success. Accelerated ocean acidification from elevated CO2 threatens the ability of crabs to detect and respond to important olfactory‐related cues. Here, we demonstrate that the ecologically and economically important Dungeness crab (Metacarcinus magister) exhibits reduced olfactory‐related antennular flicking responses to a food cue when exposed to near‐future CO2 levels, adding to the growing body of evidence of impaired crab behaviour. Underlying this altered behaviour, we find that crabs have lower olfactory nerve sensitivities (twofold reduction in antennular nerve activity) in response to a food cue when exposed to elevated CO2. This suggests that near‐future CO2 levels will impact the threshold of detection of food by crabs. We also show that lower olfactory nerve sensitivity in elevated CO2 is accompanied by a decrease in the olfactory sensory neuron (OSN) expression of a principal chemosensory receptor protein, ionotropic receptor 25a (IR25a) which is fundamental for odorant coding and olfactory signalling cascades. The OSNs also exhibit morphological changes in the form of decreased surface areas of their somata. This study provides the first evidence of the effects of high CO2 levels at multiple levels of biological organization in marine crabs, linking physiological and cellular changes with whole animal behavioural responses.

AbstractAimCoastal fishes have a fundamental role in marine ecosystem functioning and contributions to people, but face increasing threats due to climate change, habitat degradation and overexploitation. The extent to which human pressures are impacting coastal fish biodiversity in comparison with geographic and environmental factors at large spatial scale is still under scrutiny. Here, we took advantage of environmental DNA (eDNA) metabarcoding to investigate the relationship between fish biodiversity, including taxonomic and genetic components, and environmental but also socio‐economic factors.LocationTropical, temperate and polar coastal areas.Time periodPresent day.Major taxa studiedMarine fishes.MethodsWe analysed fish eDNA in 263 stations (samples) in 68 sites distributed across polar, temperate and tropical regions. We modelled the effect of environmental, geographic and socio‐economic factors on α‐ and β‐diversity. We then computed the partial effect of each factor on several fish biodiversity components using taxonomic molecular units (MOTU) and genetic sequences. We also investigated the relationship between fish genetic α‐ and β‐diversity measured from our barcodes, and phylogenetic but also functional diversity.ResultsWe show that fish eDNA MOTU and sequence α‐ and β‐diversity have the strongest correlation with environmental factors on coastal ecosystems worldwide. However, our models also reveal a negative correlation between biodiversity and human dependence on marine ecosystems. In areas with high dependence, diversity of all fish, cryptobenthic fish and large fish MOTUs declined steeply. Finally, we show that a sequence diversity index, accounting for genetic distance between pairs of MOTUs, within and between communities, is a reliable proxy of phylogenetic and functional diversity.Main conclusionsTogether, our results demonstrate that short eDNA sequences can be used to assess climate and direct human impacts on marine biodiversity at large scale in the Anthropocene and can further be extended to investigate biodiversity in its phylogenetic and functional dimensions.
The role of efferocytosis‐fueled macrophage metabolism in the resolution of inflammation

Published: May 2023

SummaryThe phagocytosis of dying cells by macrophages, termed efferocytosis, is a tightly regulated process that involves the sensing, binding, engulfment, and digestion of apoptotic cells. Efferocytosis not only prevents tissue necrosis and inflammation caused by secondary necrosis of dying cells, but it also promotes pro‐resolving signaling in macrophages, which is essential for tissue resolution and repair following injury or inflammation. An important factor that contributes to this pro‐resolving reprogramming is the cargo that is released from apoptotic cells after their engulfment and phagolysosomal digestion by macrophages. The apoptotic cell cargo contains amino acids, nucleotides, fatty acids, and cholesterol that function as metabolites and signaling molecules to bring about this re‐programming. Here, we review efferocytosis‐induced changes in macrophage metabolism that mediate the pro‐resolving functions of macrophages. We also discuss various strategies, challenges, and future perspectives related to drugging efferocytosis‐fueled macrophage metabolism as strategy to dampen inflammation and promote resolution in chronic inflammatory diseases.
Article impact of the Financial Times 50 management journals
Authors: Johnson Scott G. , Hart Timothy A. , Fox Corey J. 
Published: May 2023

AbstractAn academic journal is produced by a voluntary organization of scholars who create bodies of common knowledge consisting of the journal's published articles, along with all the references that link to the sources of knowledge for those articles. Even journals in the same discipline develop distinct bodies of common knowledge. New articles simultaneously build on and contribute to this common knowledge and we argue that this interaction with a journal's common knowledge influences how an article will be cited in the future. We explore the ecosystem identified by the Financial Times 50 management journals, demonstrating the overlap and distinction in their common knowledge. We find that journals fundamentally differ in the body of knowledge that comprises them, the sources of knowledge that contribute to them, and the journals to which they make an impact. Our findings generate novel insights into how the references cited in an article affect future citations.

Published: May 2023

AbstractOxide glasses are dielectric materials with potential applications in high‐frequency communications; hence, their dielectric properties in the gigahertz to terahertz frequency range should be investigated. In this study, the dielectric properties of silica glass and five single alkali silicate glasses were measured at 0.5–10 THz using terahertz time‐domain spectroscopy and far‐infrared spectroscopic ellipsometry. At 0.5–10 THz, the silica glass exhibited low dielectric dispersion with a low dielectric constant and loss. By contrast, the alkali silicate glasses exhibited high dielectric dispersion, and the dielectric constant and loss were higher than those of the silica glass. The shape of the dielectric dispersion profile depended on the alkali‐metal ions; it was broader for lighter ions such as Li ions and sharper for heavier ions such as Cs ions. The peak dielectric loss shifted toward a lower frequency as the weight of the alkali‐metal ions in the alkali‐silicate glass increased. To understand the dielectric dispersion, the complex permittivity was calculated using molecular dynamics simulations. The theoretical results qualitatively agreed with the experimental data. Ion dynamics analysis revealed that alkali‐metal ions vibrate and migrate under an applied electric field, which affects the dielectric constant and loss of alkali‐silicate glasses at gigahertz to terahertz frequencies. To fabricate filter devices at low temperatures, alkali metals should be added to silicate glass; therefore, a minimum amount of light alkali metals should be used to minimize the dielectric loss of the glass materials while maintaining productivity.
Effects of Ca–Gd co‐substitution on the structural, magnetic, and dielectric properties of M‐type strontium hexaferrite

AbstractSr1−xCaxFe12−xGdxO19 (x = 0, 0.04, 0.08, 0.12, 0.16, 0.20) hexaferrites were characterized by several techniques, such as X‐ray diffraction, scanning electron microscopy (SEM), energy‐dispersive X‐ray spectroscopy, and vibrating sample magnetometer. Structural results indicate the formation of a pure‐phase Sr1−xCaxFe12−xGdxO19 hexaferrite with space group P63/mmc. SEM photography confirms that there are a smaller number of defects due to the reduced porosity and surface area (increased particle size). Magnetic investigations showed a rise of the coercive force from 5069.8 to 5757.4 Oe and saturation magnetization from 79.25 to 80.68 emu/g. The maximum values appear to be for sample x = 0.16, which may be useful in such as permanent magnets, and high‐density media for magnetic storage devices. Dielectric parameters, such as conductivity, the real part of permittivity, dielectric loss, dielectric tangent loss, and complex modulus, were studied. Impedance analysis shows that the conduction process is mainly governed by the long‐range movement of the charge carriers based on the Debye model for x = 0.12.

Published: May 2023

AbstractInternal identity asymmetry is the uncomfortable experience of having one's identity mistaken—feeling being misidentified—by others at work. Through two longitudinal field studies of working individuals, we investigate the consequences of internal identity asymmetry on individuals' attitudes and work performance. Importantly, we incorporate the stress and coping literature to examine how the individual's cognitive appraisal of the asymmetry (of negative affect and coping resources), together moderate the experience. Furthermore, our results also show that appraisals of negative affect and coping resources moderate the relationship between internal identity asymmetry and performance, such that identity asymmetry may also motivate increased performance at work, depending on this appraisal. Our findings shed light on the importance of cognitive appraisal for identity incongruent experiences at work, and how they might be harnessed for positive outcomes depending on appraisal, which can be developed and strengthened over time.
Amelogenesis imperfecta: More than just an enamel problem
Authors: Morr Tal 
Published: May 2023

AbstractObjectivesThis article will provide an overview of the clinical presentation, treatment considerations, and sequencing of treatment for a patient with amelogenesis imperfecta (AI). The different types and subgroups of AI will be described, focusing on Type I hypoplastic form of the condition.OverviewPatients with AI all have abnormal enamel formation but some may also present with vertical dysgnathia, anterior open bite, and posterior crossbite. A case report demonstrates the sequencing and implementation of necessary orthodontic and prosthodontic treatments, beginning in the mixed dentition and ending with esthetic and functional permanent restorations in the permanent dentition.Clinical SignificanceAI is a disorder of tooth enamel formation but may also affect the face, jaw relationship, occlusion, compromised esthetics, and can potentially cause psychological damage due to the appearance of the teeth. Treatment of AI should be initiated at a young age.

Published: May 2023

AbstractBackgroundChildhood obesity rates have been rapidly increasing worldwide. Several actions to reduce this trend have addressed maternal feeding practices. However, research reports an unwillingness to taste healthful foods expressed by children and fathers, which represents a major obstacle to a healthy diet in the family household. The present study aims to propose and qualitatively evaluate an intervention to increase fathers' involvement with their families' healthy eating through exposure to new/disliked healthy foods.MethodsFifteen Danish families took part in a 4‐week online intervention involving picture book reading, a sensory experience session and the cooking of four recipes with four targeted vegetables (celeriac, Brussels sprouts, spinach and kale) and two spices (turmeric and ginger). Interviews were conducted with the families and the content was analysed through a blended or abductive approach.ResultsParticipating in the activities motivated children and fathers to try new vegetables and spices, and increased fathers' sense of self‐efficacy toward cooking, tasting new foods and healthy feeding. For the family, the intervention acted as a trigger to consume a higher variety of vegetables and spices and prompted feelings of “food joy”. The outcomes observed are of importance considering the relatively low cost and the remote approach of the intervention.ConclusionsThe results highlight the fact that fathers play an important role in the home food environment. We conclude that fathers should be included to a higher extent in food and nutrition strategies aimed at promoting healthy weight development in their children.

AbstractMyasthenia gravis (MG) is an antibody‐mediated autoimmune disorder characterized by fluctuation of fatigue and weakness of muscle. Due to the heterogeneity of the course of MG, available biomarkers for prognostic prediction are urgently needed. Ceramide (Cer) was reported to participate in immune regulation and many autoimmune diseases, but its effects on MG remain undefined. This study aimed to investigate the ceramides expression levels in MG patients and their potential as novel biomarkers of disease severity. Levels of plasma ceramides were determined by ultra performance liquid chromatography–tandem mass spectrometry (UPLC‐MS/MS). Severity of disease was assessed by quantitative MG scores (QMGs), MG‐specific activities of daily living scale (MG‐ADLs) and 15‐item MG quality of Life (MG‐QOL15). The concentrations of serum interleukin‐1β (IL‐1β), IL‐6, IL‐17A, and IL‐21 were determined by enzyme‐linked immunosorbent assay (ELISA), and the proportions of circulating memory B cells and plasmablasts were detected by flow‐cytometry assay. Four plasma ceramides levels we studied were detected higher in MG patients. And three of them (C16:0‐Cer, C18:0‐Cer, and C24:0‐Cer) were positively associated with QMGs. In addition, receiver operating characteristic (ROC) analysis suggested that plasma ceramides have a good ability of differentiating MG from HCs. Importantly, only C18:0‐Cer was shown to be positively associated with the concentration of serum IL and circulating memory B cells, and the decrease in plasma C18:0‐Cer paralleled the clinical improvement of patients with MG. All together, our data suggest that ceramides may play an important role in the immunopathological mechanism of MG, and C18:0‐Cer has the potential to be a novel biomarker for disease severity in MG.image

AbstractThis study was carried out to evaluate the effects of supplementation with different levels of copper (Cu) and zinc (Zn), using two mineral sources (sulphate and hydroxy forms), on the bone characteristics, skin strength/elasticity, and haematological parameters of broilers. A total of 1792 1‐day‐old male Cobb‐500 broiler chickens were randomly distributed among eight dietary treatments, using Cu sulphate (CSM) or hydroxychloride (CHC), and Zn sulphate (ZSM) or hydroxychloride (ZHC). The dietary treatments were as follows: (1) low‐CSM/high‐ZSM, (2) high‐CSM/high‐ZSM, (3) low‐CHC/low‐ZHC, (4) low‐CHC/medium‐ZHC, (5) low‐CHC/high‐ZHC, (6) high‐CHC/low‐ZHC, (7) high‐CHC/medium‐ZHC, and (8) high‐CHC/high‐ZHC. On Day 42, blood samples were collected from one bird/pen to analyze the haematological parameters. Finally, two birds/pen were slaughtered, and the tibia and femur were collected to analyze the quality of bone and skin. The means were subjected to ANOVA and, when significant, compared by Tukey's test (p < 0.05) or Dunnett's (p < 0.05) test. The haematological parameters were not influenced by mineral supplementation. However, the inclusion of low ZHC enhanced the skin strength compared to high ZHC (p = 0.046). Furthermore, the bone mineral density of the tibia proximal epiphysis, tibia ash and tibia mineral content were positively improved with supplementation of low‐CHC/medium‐ZHC compared to high‐CHC/medium‐ZHC. This study demonstrated that hydroxy compounds are potential alternatives for replacing sulphate supplements in broiler diets. Moreover, among the Cu and Zn levels, the low CHC (15 mg/kg) and medium ZHC (100 mg/kg) improved bone development and skin integrity, suggesting that the combination of Cu and Zn can be a nutritional strategy to prevent the incidence of leg disorders in broilers.

AbstractBackgroundBrucellosis in dogs caused by Brucella suis is an emerging zoonotic disease.ObjectivesTo document clinical characteristics, serology, microbiology, and clinical response to treatment in B. suis‐seropositive dogs.AnimalsLongitudinal study of 27 privately‐owned dogs. Dogs that tested positive by serology, culture, or real‐time polymerase chain reaction (qPCR) were included in the study.MethodsClinical (physical examination and imaging) and laboratory (serology, hematology, serum biochemistry, and qPCR or culture) assessments were made at baseline and after approximately 3, 6, 12, and 18 months.ResultsDogs were followed for 10 895 dog days, with 17/27 dogs completing the 18‐month follow‐up. Ten dogs had signs consistent with brucellosis before enrollment (n = 4), at baseline (n = 2) or during follow‐up (n = 6), with 2 dogs experiencing relapse of historical signs. Antibody titers persisted for the duration of follow‐up in 15/17 dogs (88%). Radiographic (n = 5) and ultrasound (n = 11) findings, of variable clinical relevance, were observed. Brucella DNA and organisms were detected in 3 dogs, all of which had clinical signs, including in the milk of a bitch around the time of whelping. Brucella DNA was not detected in blood (n = 92 samples), urine (n = 80), saliva (n = 95) or preputial swabs (n = 78) at any time during follow‐up. Six dogs underwent treatment, all of which achieved clinical remission although remission was not reflected by decreasing antibody titers.Conclusions and Clinical ImportanceMost dogs with B. suis infections have subclinical infections. Serology is poorly associated with clinical disease. Excretion of organisms appears rare except in whelping bitches. Clinical management using antibiotics with or without surgery is recommended.
