AbstractBackgroundVitiligo, an autoimmune skin disorder linked to hormonal and genetic factors, results in reduced pigmentation due to a gradual decline in melanocyte activity. This systematic review delves into the role of dietary intervention and nutrition in managing vitiligo.MethodsA comprehensive search on PubMed, Google Scholar, and European PMC identified 214 studies, with 14 meeting inclusion criteria post‐screening. The selected studies primarily explored the impact of dietary supplements on disease activity.ResultsHeavy metal exposure, specifically Cd, Pb, and Hg, indicated potential links to heightened reactive oxygen species and vitiligo development. Conflicting evidence emerged regarding the role of trace minerals (Zn and Cu), with some studies suggesting deficiencies and others proposing excesses in vitiligo patients. Vitamins with anti‐inflammatory properties like vitamin C, D, and B12, along with antioxidants, were investigated for their potential in repigmentation strategies. Additionally, polyunsaturated fatty acids (PUFAs), especially in varying types of fat consumption, were implicated. Emphasizing the need to reduce reliance on pharmacological and phototherapy interventions, the review uncovers novel roles for dietary supplements as adjuncts or flare reducers.ConclusionWhile dietary interventions cannot be thought of as a standalone therapy, they still make a case for being used as adjuncts. Large scale clinical trials are warranted to establish strong evidence and protocols, and might also help reduce the dependency on pharmacological methods, which come with their adverse effect profiles.
Daily general discrimination predicts changes in trait negative affectivity: A 30‐year cohort longitudinal study using a random‐intercept cross‐lagged panel model
Authors: Daurio Allison M. , Taylor Jeanette 
Published: March 2024

AbstractObjectiveIncreasing evidence indicates discrimination is an emerging risk factor for reducing psychological well‐being. Negative affectivity is a personality trait that has been associated with discrimination. Yet, few studies to date have examined the longitudinal relationship between discrimination and personality. The current study addresses this gap by examining how general discrimination and negative affectivity influence each other longitudinally.MethodThe Midlife in the United States (MIDUS) dataset was used for the current study. The MIDUS sample (N = 4244) was predominately white (90.7%), 52% female, and had an average age of 46 years old. Individuals completed follow‐up measures 10 and 20 years after baseline. Data were analyzed using a random‐intercept cross‐lagged panel model.ResultsIndividuals that scored higher on trait negative affectivity also tended to score higher on perceived daily discrimination. We found general perceived discrimination at age 55 unidirectionally predicted changes in negative affectivity around retirement age, but not from age 45 to 55. In contrast, negative affectivity did not significantly predict increases in perceived discrimination at any timepoint.ConclusionOur results indicate that perceived discrimination has pernicious impacts on well‐being up to a decade later and may do so by increasing an individual's tendency to experience negative emotions (i.e., negative affectivity).

AbstractIntroductionThe challenging work environments mental health nurses (MHNs) encounter can negatively impact their mental health, psychological well‐being and physical health. While these impacts have been investigated in quantitative research, little is known about work‐related stress from the perspective of MHNs.AimTo explore the stresses faced by nurses working in mental health settings and to gain an understanding of the underlying workplace context.MethodA descriptive qualitative study with data collected via semi‐structured individual telephone interviews conducted with n = 21 Western Australian MHNs. Data were analysed using reflexive thematic analysis.ResultsA total of 85 codes were generated that led to the identification of 13 subthemes and 4 main themes: (1) mental health nursing context, (2) work environment stressors, (3) factors that alleviate stress and (4) the impact of workplace stress.DiscussionMany of the stressors MHNs were exposed to are modifiable, such as understaffing and poor skill mix. Modifiable stressors increased risk for MHNs, impeded patient care and exacerbated inherent stressors such as patient acuity and complexity.Implications for PracticeThis study collected data that provide rich descriptions of the experiences of MHNs and identify modifiable work‐related stressors that could be alleviated through effective leadership and management.

AbstractQuestionsThe fluvial dynamics of meandering white‐water rivers of Amazonia drive vegetation primary succession. Directional successional processes have been recorded for the seasonal várzea forests that occupy well‐drained soils on levees and point bars across the spatial gradient of the flood‐plains. However, the types of forests occupying the swampy depressions interspersed between the point bars and their distribution along the flood‐plain's spatial gradient are poorly understood. Here, we aimed to unravel the spatial patterns of swamp forests along the sequence defined by an axis perpendicular to the river and the relationship with edaphic and spatial factors.LocationThe flood‐plains of the middle Caquetá River basin, Colombian Amazonia.MethodsForest types were identified by cluster analysis performed on 42 square plots (33 m × 33 m) set in poorly drained depressions of the flood‐plain. Floristic composition and vegetation structure as response data, and edaphic and spatial variables as predictors, were analyzed through partial redundancy analysis (pRDA). The effect of geographic position was included by using the first two axes of a principal coordinates of neighbor matrix analysis as conditional factors in the pRDA.ResultsThe three identified swamp forest types were not arranged along a directional spatial pattern. Permanent várzea forests, closest to the river, showed the greatest diversity and alluvial sediment input. Oxandrales, furthest from the river, dominated by Oxandra polyantha, showed the greatest tree density, basal area and soil sand content, and received additional flooding from black‐water streams. Cananguchales, dominated by Mauritia flexuosa, exhibited the highest dominance and soil organic matter layer thickness. Distribution of the permanent várzea and oxandrales was relatively constrained by the distance to the river, whereas that of the cananguchales was not.ConclusionsFlooding dynamics delay vegetation development of the swamp forests in permanent várzea and oxandrales. Cananguchales keep accumulating organic matter, becoming ombrotrophic peats after isolation from the river flooding influence. The swamp forests across these flood‐plains are far from being arranged along a linear sequence.
Wetting property of Fe‐S melt in solid core: Implication for the core crystallization process in planetesimals

Published: March 2024

AbstractIn differentiated planetesimals, the liquid core starts to crystallize during secular cooling, followed by the separation of liquid–solid phases in the core. The wetting property between liquid and solid iron alloys determines whether the core melts are trapped in the solid core or they can separate from the solid core during core crystallization. In this study, we performed high‐pressure experiments under the conditions of the interior of small bodies (0.5–3.0 GPa) to study the wetting property (dihedral angle) between solid Fe and liquid Fe‐S as a function of pressure and duration. The measured dihedral angles are approximately constant after 2 h and decrease with increasing pressure. The dihedral angles range from 30° to 48°, which are below the percolation threshold of 60° at 0.5–3.0 GPa. The oxygen content in the melt decreases with increasing pressure and there are strong positive correlations between the S + O or O content and the dihedral angle. Therefore, the change in the dihedral angle is likely controlled by the O content of the Fe‐S melt, and the dihedral angle tends to decrease with decreasing O content in the Fe‐S melt. Consequently, the Fe‐S melt can form interconnected networks in the solid core. In the obtained range of the dihedral angle, a certain amount of the Fe‐S melt can stably coexist with solid Fe, which would correspond to the “trapped melt” in iron meteorites. Excess amounts of the melt would migrate from the solid core over a long period of core crystallization in planetesimals.

AbstractPhosphatases are important regulators of protein phosphorylation and various cellular processes, and they serve as counterparts to kinases. In this study, our comprehensive analysis of oomycete complete proteomes unveiled the presence of approximately 3833 phosphatases, with most species estimated to have between 100 and 300 putative phosphatases. Further investigation of these phosphatases revealed a significant increase in protein serine/threonine phosphatases (PSP) within oomycetes. In particular, we extensively studied the metallo‐dependent protein phosphatase (PPM) within the PSP family in the model oomycete Phytophthora sojae. Our results showed notable differences in the expression patterns of PPMs throughout 10 life stages of P. sojae, indicating their vital roles in various stages of oomycete pathogens. Moreover, we identified 29 PPMs in P. sojae, and eight of them possessed accessory domains in addition to phosphate domains. We investigated the biological function of one PPM protein with an extra PH domain (PPM1); this protein exhibited high expression levels in both asexual developmental and infectious stages. Our analysis confirmed that PPM1 is indeed an active protein phosphatase, and its accessory domain does not affect its phosphatase activity. To delve further into its function, we generated knockout mutants of PPM1 and validated its essential roles in mycelial growth, sporangia and oospore production, as well as infectious stages. To the best of our knowledge, this study provides the first comprehensive inventory of phosphatases in oomycetes and identifies an important phosphatase within the expanded serine/threonine phosphatase group in oomycetes.

Published: March 2024

AbstractIn this study, we employed the evidential belief function model (EBF) to evaluate the potential for land subsidence in the primary aquifer of Bardaskan. Through field visits, we recorded GPS coordinates for 174 land subsidence points. Factors considered in assessing land subsidence potential included well density, groundwater extraction rate, geological characteristics, proximity to faults, vegetation cover, distance from the river, slope, and land use. To develop and validate the model, 70% of the recorded points were randomly selected for training and implementation, while the remaining 30% were reserved for model validation. The number and percentage of land subsidence points in the different classes of the corresponding layers were determined by integrating the training points with influential variables maps such as distance from the river, distance from the fault, land use, and extraction volume. The EBF model rate was calculated for different layer classes. For modeling, all rates of the EBF model in each cell were summated, and the ‎potential of land subsidence was calculated.‎ Finally, the map of land subsidence potential based on the EBF model was determined with GIS. The results showed that most of the subsidence points were located in alluvial sediment of the Holocene period, in areas with high groundwater harvesting, a distance of at least 3000 m from a river, a distance of at least 6000 m from a fault, low‐density rangelands, slopes of at least 0%–2%, and farmlands and gardens. A receiver operating characteristic curve analysis of the EBF model showed that it could accurately predict land subsidence in 87.5% of cases using 30% of the validation data. This suggests that the model can be used for practical applications.

Abstract
Ammonium nitrogen (NH4+‐N) is essential for fruit tree growth, but the impact of excess NH4+‐N from fertilizer on evergreen citrus trees is unclear.
In a climate chamber, 8‐month‐old citrus plants were exposed to five different hydroponic NH4+‐N concentrations (0, 5, 10, 15 and 20 mm) for 1 month to study effects of NH4+‐N on growth characteristics, N uptake, metabolism, antioxidant enzymes and osmotic regulatory substances.
Application of 10 mm NH4+‐N adversely affected root plasma membrane integrity, root physiological functions, and plant biomass. MDA, CAT, POD, APX and SOD content were significantly correlated with leaf N metabolic enzyme activity (GOGAT, GDH, GS and NR). GDH was the primary enzyme involved in NH4+‐N assimilation in leaves, while the primary pathway involved in roots was GS‐GOGAT.
Under comparatively high NH4+ addition, roots were the main organs involved in NH4+ utilization in citrus seedlings. Our results demonstrated that variations in NH4+ concentration and enzyme activity in various organs are associated with more effective N metabolism in roots than in leaves to prevent NH4+ toxicity in evergreen woody citrus plants. These results provide insight into the N forms used by citrus plants that are important for N fertilizer management.
A critical evaluation and research agenda for the study of psychological dispositions and political attitudes

Published: March 2024

AbstractPolitical psychologists often examine the influence of psychological dispositions on political attitudes. Central to this field is the ideological asymmetry hypothesis (IAH), which asserts significant psychological differences between conservatives and liberals. According to the IAH, conservatives tend to exhibit greater resistance to change, a stronger inclination to uphold existing social systems, and heightened sensitivity to threats and uncertainty compared with their liberal counterparts. Our review and reanalysis, however, question the empirical strength of the IAH. We expose major concerns regarding the construct validity of the psychological dispositions and political attitudes traditionally measured. Furthermore, our research reveals that the internal validity of these studies is often compromised by endogeneity and selection biases. External and statistical validity issues are also evident, with many findings relying on small effect sizes derived from nonrepresentative student populations. Collectively, these data offer scant support for the IAH, indicating that simply amassing similar data is unlikely to clarify the validity of the hypothesis. We suggest a more intricate causal model that addresses the intricate dynamics between psychological dispositions and political attitudes. This model considers the bidirectional nature of these relationships and the moderating roles of individual and situational variables. In conclusion, we call for developing more sophisticated theories and rigorous research methodologies to enhance our comprehension of the psychological underpinnings of political ideology.

Published: March 2024

AbstractCryopreservation is one of the reliable techniques for long‐term storage of sperm. The success of this technique depends on the choice of cryoprotectant; therefore, a plethora of literature has reported the effects of different cryoprotective agents so far. Kappa‐carrageenan (κ‐carrageenan) is a hydrocolloid polysaccharide extracted from red marine seaweed. Its unique property makes it a promising option as a non‐colligative cryoprotectant. The current study aims to evaluate the cryoprotective effect of k‐carrageenan along with glycerol on ram sperm quality both after equilibration and freezing. Nine Kajli rams were utilized in this experiment for semen collection through an artificial vagina maintained at 42°C. Qualified samples were diluted in tris egg yolk glycerol (TEYG) extender containing different concentrations of k‐carrageenan as 0 mg/mL (control), 0.2, 0.5, 0.8 and 1 mg/mL. Post‐thaw assessment was done at 37°C after 24 h of storage, which showed a significant improvement (p < .05) in sperm viability, motility, membrane and acrosome integrity in an extender containing k‐carrageenan at a concentration of 0.5 mg/mL compared to control. It is concluded from the current study that the combination of glycerol and 0.5 mg/mL concentration of k‐carrageenan improved the sperm post‐thaw quality.
Unofficial intermediation in the regulatory governance of hazardous chemicals
Authors: Hysing Erik , Du Rietz Dahlström Sabina 
Published: March 2024

AbstractRegulatory intermediaries—organizations that operate between regulators (public and private) and target groups—perform a range of important functions. While most previous research has focused on intermediaries that have been delegated official authority, in this paper we focus on unofficial and informal intermediary functions aiming to advance the governance of per‐ and polyfluoroalkyl substances (PFAS) chemicals. Chemical pollution is a growing environmental and health concern, leading to both public and private regulatory initiatives. By studying a particular segment—paperboard food packaging in Sweden—the study generates insights into critical functions performed by unofficial intermediaries (Svenskt Vatten and ChemSec) in this regulatory regime, which extend and expand regulatory reach in various ways. The study also shows the importance of different types of intermediaries that interact in dynamic ways, and the role of material artifacts in processes of intermediation. These unofficial functions are arguably important for the functioning of complex, hybrid forms of governance, but they also prompt critical questions about the effectiveness, legitimacy, and role of intermediaries in generating needed transformative change.

AbstractLegislative bodies generally keep records of their activities. While the digitization wave spurred the availability of archival documents, their processing remains a challenge. The Swiss parliamentary records are no exception.In this paper we present a supervised pipeline for extracting and structuring of content of archival records. Our pipeline consists of five steps, starting with an assessment of which elements need extraction and how they relate to each other. Step two involves general pre‐processing to prepare the PDF documents and is followed by an element classification step. Step four involves post‐processing and the final step is a validation of the extracted information. With our supervised approach, we are able to process over 200,000 pages of Swiss parliamentary records (spanning the years 1891–1995), a feat that would exceed the budget of most projects using manual curation. We discuss validation of individual steps and offer guidance to researchers engaged in similar data processing efforts.
An economy of immunity: The racial‐spatial lives of antibodies in the American blood plasma economy from 1960s prisons to COVID‐19
Authors: Johnson Kelsey 
Published: March 2024

AbstractIn 2020, a market in convalescent blood plasma developed as a potential treatment for COVID‐19. During this time, commercial plasma centres—which collect the blood plasma from paid donors for pharmaceutical production—paid recovered patients as much as US$100 for a donation of blood plasma containing COVID‐19 antibodies, from which they manufactured an experimental treatment. This paper uses the commercial collection of COVID‐19 antibodies found in plasma as an entry point into exploring how racially uneven exposures to disease may produce biovalue. The first section considers the spatial history of antibody‐derived plasma products, using historical research to examine how inmates at predominantly black plantation‐prisons in the US South were valued for antibody production in the 1960s. Against this historical relief, the second section examines the spatiality of antibodies in current practices of the plasma industry, as well as in the plasma industry's response to the COVID‐19 pandemic (even as those efforts eventually failed in clinical trials). If geographical literatures on environmental exposure, as well as on COVID‐19 transmission, discuss exposure as an outcome of racial capitalism, this paper emphasises the productive opportunities that capital can solicit from exposures, especially those that are useful to different forms of biomedicine. By critically scrutinising the practice of ‘sharing immunity’ and attending to its decidedly geographic constitution, we can see how what Ruth Wilson Gilmore calls the ‘death‐dealing logics’ of racial capitalism may also work through the seemingly affirmative practices and communal imaginaries behind the redistribution of antibodies as medicine.
