Calcium influx rapidly establishes distinct spatial recruitments of Annexins to cell wounds
Authors: Nakamura Mitsutoshi , Parkhurst Susan M 
Published: June 2024

Abstract
To survive daily damage, the formation of actomyosin ring at the wound edge is required to rapidly close cell wounds. Calcium influx is one of the start signals for these cell wound repair events. Here, we find that the rapid recruitment of all 3 Drosophila calcium-responding and phospholipid-binding Annexin proteins (AnxB9, AnxB10, and AnxB11) to distinct regions around the wound is regulated by the quantity of calcium influx rather than their binding to specific phospholipids. The distinct recruitment patterns of these Annexins regulate the subsequent recruitment of RhoGEF2 and RhoGEF3 through actin stabilization to form a robust actomyosin ring. Surprisingly, while the wound does not close in the absence of calcium influx, we find that reduced calcium influx can still initiate repair processes, albeit leading to severe repair phenotypes. Thus, our results suggest that, in addition to initiating repair events, the quantity of calcium influx is important for precise Annexin spatiotemporal protein recruitment to cell wounds and efficient wound repair.

Abstract
Delirium, a syndrome characterized by an acute change in attention, awareness, and cognition, is commonly observed in older adults, although there are few quantitative monitoring methods in the clinical setting. We developed a bispectral electroencephalography (BSEEG) method capable of detecting delirium and can quantify the severity of delirium using a novel algorithm. Preclinical application of this novel BSEEG method can capture a delirium-like state in mice following lipopolysaccharide administration. However, its application to postoperative delirium (POD) has not yet been validated in animal experiments. This study aimed to create a POD model in mice with the BSEEG method by monitoring BSEEG scores following EEG head-mount implantation surgery and throughout the recovery. We compared the BSEEG scores of C57BL/6J young (2–3 months old) with aged (18–19 months old) male mice for quantitative evaluation of POD-like states. Postoperatively, both groups displayed increased BSEEG scores and a loss of regular diurnal changes in BSEEG scores. In young mice, BSEEG scores and regular diurnal changes recovered relatively quickly to baseline by postoperative day (PO-Day) 3. Conversely, aged mice exhibited prolonged increases in postoperative BSEEG scores and it reached steady states only after PO-Day 8. This study suggests that the BSEEG method can be utilized as a quantitative measure of POD and assess the effect of aging on recovery from POD in the preclinical model.

Abstract

Background
In recent years, the life expectancy of human immunodeficiency virus (HIV)-infected children has increased with the availability of highly active antiretroviral therapy (ART). Regardless of the clinical recommendations encouraging HIV status disclosure, the practice of caregiver disclosure is frequently challenging due to many constraints associated with caregivers and healthcare personnel. As studies suggest, disclosure of the HIV-positive status of children is low, particularly in sub-Saharan Africa, where the majority of infected children reside. Thus the primary objective of this study was to evaluate the prevalence of HIV-positive status disclosure to infected children and the pertinent factors associated with caregivers of these children. Moreover, unlike previous studies conducted in Ethiopia, this study included children residing in orphanages.

Methods
We assessed HIV-positive status disclosure and associated factors among infected children in Hawassa, southern Ethiopia, from 25 May to 20 July 2021. A facility-based cross-sectional study was conducted in six public health facilities that provide HIV treatment and care. Data were collected from 355 randomly selected caregivers using interviewer-administered questionnaires and record reviews. Binary and multiple logistic regression was used to explore the association between independent variables and the outcome. The adjusted odds ratio (aOR) with 95% confidence interval (CI) was computed to determine the strength of the association and a p-value &lt;0.05 was considered statistically significant.

Results
Of the 355 children, 132 (37.2%) were informed about their HIV-positive status. Being of young age (≤12 y) (aOR 0.52 [95% CI 0.28 to 0.98]), having caregivers who were not familiar with anyone who disclosed children's HIV status (aOR 0.28 [95% CI 0.16 to 0.49]), children with a family that had a primary education (aOR 0.46 [95% CI 0.23 to 0.89]) and being a child who has taken ART for &lt;5 y (aOR 0.47 [95% CI 0.28 to 0.80]) had a significant association with non-disclosure of HIV-positive status to infected children.

Conclusions
The findings show that disclosure of HIV-positive status to infected children is low. This suggests the need to provide support and education to caregivers, facilitate experience-sharing sessions between caregivers who disclosed the HIV status to infected children and implement age-specific disclosure interventions for young children. In addition, it is important to provide support and counselling to the children when their HIV status is disclosed.
Genome-wide screen of genetic determinants that govern Escherichia coli growth and persistence in lake water

Published: June 2024

Abstract
Although enteric bacteria normally reside within the animal intestine, the ability to persist extraintestinally is an essential part of their overall lifestyle, and it might contribute to transmission between hosts. Despite this potential importance, few genetic determinants of extraintestinal growth and survival have been identified, even for the best-studied model, Escherichia coli. In this work, we thus used a genome-wide library of barcoded transposon insertions to systematically identify functional clusters of genes that are crucial for E. coli fitness in lake water. Our results revealed that inactivation of pathways involved in maintaining outer membrane integrity, nucleotide biosynthesis, and chemotaxis negatively affected E. coli growth or survival in this extraintestinal environment. In contrast, inactivation of another group of genes apparently benefited E. coli growth or persistence in filtered lake water, resulting in higher abundance of these mutants. This group included rpoS, which encodes the general stress response sigma factor, as well as genes encoding several other global transcriptional regulators and RNA chaperones, along with several poorly annotated genes. Based on this co-enrichment, we identified these gene products as novel positive regulators of RpoS activity. We further observed that, despite their enhanced growth, E. coli mutants with inactive RpoS had reduced viability in lake water, and they were not enriched in the presence of the autochthonous microbiota. This highlights the duality of the general stress response pathway for E. coli growth outside the host.

Abstract
Chronic hyperglycemia can result in damage to the hippocampus and dysfunction of the blood-brain barrier (BBB), potentially leading to neurological disorders. This study examined the histological structure of the hippocampus and the expression of critical genes associated with the BBB at 2 early stage time points in a streptozotocin-induced diabetes mellitus (DM) mouse model. Routine histology revealed vascular congestion and dilation of Virchow-Robin spaces in the hippocampal CA1 region of the DM group. Neuronal alterations included rounding and swelling and reduction in Nissl bodies and increased apoptosis. Compared to the control group, TJP1 mRNA expression in the DM group was significantly lower (P &lt; .05 or P &lt; .01), while mRNA levels of JAM3, TJP3, CLDN5, CLDN3, and OCLN initially increased and then decreased. At 7, 14, and 21 days, mRNA levels of the receptor for advanced glycation end products (AGER) were greater in the DM group than in the control group (P &lt; .05 or P &lt; .01). These findings indicate that early-stage diabetes may cause structural and functional impairments in hippocampal CA1 in mice. These abnormalities may parallel alterations in the expression of key BBB tight junction molecules and elevated AGER expression in early DM patients.
Doing legality as doing drag: the Yogyakarta Principles and the productive power of performing international law-making
Authors: Santos de Carvalho Juliana 
Published: June 2024

Abstract
Despite being elaborated by experts, the Yogyakarta Principles on sexual orientation and gender identity (YP) strongly resemble an international human rights treaty in their language and format. Building on drag performances, I argue that, instead of merely imitating law, the YP creatively disturb the borders of international law-making.
Gender, fertility, and employment among African women in Spain, 2000–2020
Authors: Gastón-Guiu Silvia , Bueno Xiana 
Published: June 2024

Abstract
The African population is among those with the largest migratory tradition in Spain. During the period of economic growth, migratory flows from Africa were mostly men and of an economic nature, while the majority of women embarked on their migratory projects for family reunification. However, the ensuing socioeconomic circumstances led to variations in these trends. The aim of this study is to explore how changes in the economic cycle during the last two decades have affected the reproductive behavior of African migrant women, with particular attention to their relationship with the Spanish labor market from a couple-level perspective. We analyze longitudinal data from the Spanish Labor Force Survey from 2000 to 2020. The results show how the Great Recession had the effect of lowering fertility throughout the sample. Notably, unlike other origins, for African-born women, the negative effect on fertility endures during the recovery period, even when controlling for other factors. Results also suggest that when African women transition from inactivity to unemployment, the probability of having a child is lower compared with the traditional gender-role model. However, the fertility of African couples with a favorable education and employment position for both partners is not significantly different from that of couples representing the traditional model. Our results might be pointing toward changes in gender roles among couples of African origin in Spain, at least in the domain of the labor market. Future research should explore whether these changes extend to the private sphere within families.
Application of the Modified Grunow-Finke Risk Assessment Tool to the Sverdlovsk Anthrax Outbreak of 1979
Authors: Zhang Pan , MacIntyre C. Raina , Chen Xin , Chughtai Abrar A 
Published: June 2024

ABSTRACT

Introduction
The modified Grunow-Finke tool (mGFT) is an improved scoring system for distinguishing unnatural outbreaks from natural ones. The 1979 Sverdlovsk anthrax outbreak was due to the inhalation of anthrax spores from a military laboratory, confirmed by Russian President Boris Yeltsin in 1992. At the time the Soviet Union insisted that the outbreak was caused by meat contaminated by diseased animals. At the time there was no available risk assessment tool capable of thoroughly examine the origin of the outbreak.

Methods
This study aimed to retrospectively apply the mGFT to test its ability to correctly identify the origin of the Sverdlovsk anthrax outbreak of 1979 as unnatural, using data available up to 1992, before the disclosure of a laboratory leak. Data spanning from 1979 to 1992 were collected through literature reviews. Evidence related to each mGFT criterion was scored on a scale of 0 to 3 and independently reviewed by 3 assessors. These scores were then multiplied with a weighting factor and summed to obtain a maximum score. A final score exceeding 30 was indicative of an unnatural origin.

Results
The mGFT results assigned a total of 47 points to the Sverdlovsk anthrax outbreak, suggesting an unnatural origin with a 78% likelihood.

Conclusions
These findings align with the confirmed unnatural origin of the outbreak, highlighting the value of tools such as the mGFT in identifying unnatural outbreaks. Such tools integrate both intelligence evidence and biological evidence in the identification of unnatural outbreaks. The use of such tools for identifying unnatural outbreaks is limited. Outbreak investigation can be improved if risk assessment tools become integral to routine public health practice and outbreak investigations.
Factors That Influence Health Care–Seeking Behavior and Health Information Disclosure Among U.S. Air Force Pilots
Authors: Goodman Tanya M , Martinez Rachael N , Giarrusso Nicole L , Thompson Christopher , Hoffman William R 
Published: June 2024

ABSTRACT

Introduction
The reality of pilot health care avoidance behavior is often common knowledge to both pilots and aeromedical physicians, but the underlying factors leading to this behavior are less understood. In the current study, we conducted a qualitative assessment of a sample of U.S. Air Force (USAF) pilots to gather firsthand perceptions of the factors that encourage and discourage disclosure during aeromedical screening and use of mental and physical health care services, as well as recommendations to improve the USAF aeromedical health care system.

Materials and Methods
We conducted interviews with 21 USAF pilots on their perceptions of seeking medical care to identify factors that uniquely discourage or encourage disclosure and health care utilization to understand factors that aid the aeromedical provider/aviator relationship and to elicit interventions that could be prospectively researched. This work was reviewed by the Air Force Research Laboratory Institutional Review Board at Wright-Patterson Air Force Base and designated as exempt research, FWR20220103E.

Results
The most reported factors that discourage military pilot health care disclosure and health care utilization overall were medical revocation, stigma, and lack of trust in providers. Unit-embedded services, ease of access, and severity of condition were the most reported factors encouraging disclosure and utilization. Factor descriptions and exemplary quotes from pilots and pilot recommendations to encourage health care utilization and disclosure are provided.

Conclusions
Results from firsthand interviews with pilots provide valuable information for flight surgeons to focus on building trust with their pilots to reduce health care avoidance.
Biases in ARG-Based Inference of Historical Population Size in Populations Experiencing Selection
Authors: Marsh Jacob I , Johri Parul 
Published: June 2024

Abstract
Inferring the demographic history of populations provides fundamental insights into species dynamics and is essential for developing a null model to accurately study selective processes. However, background selection and selective sweeps can produce genomic signatures at linked sites that mimic or mask signals associated with historical population size change. While the theoretical biases introduced by the linked effects of selection have been well established, it is unclear whether ancestral recombination graph (ARG)-based approaches to demographic inference in typical empirical analyses are susceptible to misinference due to these effects. To address this, we developed highly realistic forward simulations of human and Drosophila melanogaster populations, including empirically estimated variability of gene density, mutation rates, recombination rates, purifying, and positive selection, across different historical demographic scenarios, to broadly assess the impact of selection on demographic inference using a genealogy-based approach. Our results indicate that the linked effects of selection minimally impact demographic inference for human populations, although it could cause misinference in populations with similar genome architecture and population parameters experiencing more frequent recurrent sweeps. We found that accurate demographic inference of D. melanogaster populations by ARG-based methods is compromised by the presence of pervasive background selection alone, leading to spurious inferences of recent population expansion, which may be further worsened by recurrent sweeps, depending on the proportion and strength of beneficial mutations. Caution and additional testing with species-specific simulations are needed when inferring population history with non-human populations using ARG-based approaches to avoid misinference due to the linked effects of selection.
Revision of the British Lower Jurassic Astartinae (Bivalvia)
Authors: Knight Robin I , Collins Katie S , Morris Noel J 
Published: June 2024

ABSTRACT
The Astartidae (Bivalvia) are a common benthic fossil in the British Lower Jurassic and as such it is important to understand their taxonomy so as to use them as a study system with which to consider environmental change through, and extinction events in, this epoch. The majority of the species of the Astartidae from the British Lower Jurassic are taxa within the subfamily Astartinae, encompassing the genera Neocrassina, Coelastarte and Oxyeurax. There has been some question as to whether those shells attributed to Neocrassina could be further split, with two species assigned to this genus having some characters that are atypical. We prefer to retain the atypical species within ?Neocrassina, the genus with which they have the greatest affinity, rather than erect another genus. This study assigns the suite of British Lower Jurassic fossil bivalves attributed to Nicaniella to Oxyeurax, based on the presence of a poorly defined 3a tooth and form of commarginal ridge ornament. Differentiation at the species level in Astartinae is complicated; the subfamily exhibits generally low disparity compared with other bivalves, compounded by ecomorphological effects and, in some cases, sexual dimorphism. We show that the Neocrassina lineage exhibits gradual changes in shape, as well as hinge plate development and complexity, through the Lower Jurassic, and identify potential sexual dimorphism in species of Oxyeurax. The temporally overlapping species of Oxyeurax display varying degrees of ornamental development which may well be environmentally controlled and are used in this study to define distinct new species. This study recognizes 12 distinct species of Astartinae from the British Lower Jurassic. Nine are established taxa (Neocrassina elegans, N. expansa, N. gueuxii, N. lurida, N. phaedra, ?N. camertonensis, ?N. dentilabrum, Oxyeurax duplicata, O. striatosulcata), whilstthree are new species (Coelastarte wardenensis, O. mickletonensis and Oxyeurax thompsoni). Only two of the British Lower Jurassic Astartinae species appear to have survived the global Early Toarcian extinction event as represented in British successions; one Neocrassina and one Oxyeurax. However, the lack of fossiliferous, high energy near shore environments in the early Toarcian may bias this observation, especially for Oxyeurax.

Abstract
Mass spectrometry is a powerful and widely used tool for generating proteomics, lipidomics and metabolomics profiles, which is pivotal for elucidating biological processes and identifying biomarkers. However, missing values in mass spectrometry-based omics data may pose a critical challenge for the comprehensive identification of biomarkers and elucidation of the biological processes underlying human complex disorders. To alleviate this issue, various imputation methods for mass spectrometry-based omics data have been developed. However, a comprehensive comparison of these imputation methods is still lacking, and researchers are frequently confronted with a multitude of options without a clear rationale for method selection. To address this pressing need, we developed omicsMIC (mass spectrometry-based omics with Missing values Imputation methods Comparison platform), an interactive platform that provides researchers with a versatile framework to evaluate the performance of 28 diverse imputation methods. omicsMIC offers a nuanced perspective, acknowledging the inherent heterogeneity in biological data and the unique attributes of each dataset. Our platform empowers researchers to make data-driven decisions in imputation method selection based on real-time visualizations of the outcomes associated with different imputation strategies. The comprehensive benchmarking and versatility of omicsMIC make it a valuable tool for the scientific community engaged in mass spectrometry-based omics research. omicsMIC is freely available at https://github.com/WQLin8/omicsMIC.

Published: June 2024

Abstract

Background
In 2017, a mumps outbreak occurred in a US military barracks. Serum collected at service entry was used to compare pre-exposure with presumptive vaccine-induced antibody levels from persons who developed mumps (cases) and potentially exposed persons who did not develop mumps (non-cases). Sufficient information to determine levels of exposure during the outbreak was not available.

Methods
Pre-outbreak serum samples from the Department of Defense Serum Repository were available from 254 potentially exposed service members. Twelve developed clinical symptoms and had post-outbreak serum collected. All sera were tested with a mumps-specific enzyme immunoassay for immunoglobulin M, immunoglobulin G (IgG), and IgG avidity. The neutralizing antibodies to vaccine strain (Jeryl Lynn [JL], genotype A) and wildtype virus (genotype G) was assessed by a plaque reduction neutralization test. A Fisher exact test and receiver operator characteristic curve were used to analyze the antibody response for non-cases and mumps cases.

Results
Eight mumps cases were laboratory confirmed. Pre-outbreak neutralizing antibody titers to JL and genotype G mumps virus and pre-outbreak IgG index values were proportionately lower for most cases as compared with exposed non-cases. When compared with potentially exposed non-cases, cases with clinical symptoms had greater odds of having a pre-outbreak JL titer &lt;41 and a genotype G titer &lt;16.

Conclusions
We identified potential correlates of protection for mumps neutralizing antibody titers against JL and genotype G mumps viruses.
