Filial cannibalism in teleost fish
Authors: MANICA ANDREA 
Published: July 2002

ABSTRACTThis review summarizes information on filial cannibalism (the act of eating one's own offspring) in teleost fish. Cannibalistic parents can either consume their whole brood (total filial cannibalism), or eat only some of the eggs in the nest (partial filial cannibalism). Offspring consumption has been argued to be adaptive under the assumption that offspring survival is traded against feeding, and that offspring can act as an alternative food source for the parents. The evidence supporting the basic predictions formulated under these assumptions is summarized for both total and partial filial cannibalism. These two forms of cannibalism differ significantly since the former represents an investment only in future reproductive success, whereas the latter can affect both present and future reproductive success. Despite a few inconsistencies in the data from laboratory and field studies, the energy‐based explanation appears valid for both forms of cannibalism. Alternative non‐energy‐based explanations are considered, but they are unable to account for the wide distribution of this behaviour in teleosts. The intersexual conflict arising from attempts of the non‐cannibal sex to minimize the cost of filial cannibalism is also discussed, together with the potential effect of this behaviour on the operational sex ratio at a population level.

Published: February 2025

Abstract

Objectives
This study explored bereaved relatives’ experiences of end-of-life care (EoL care) in the last 3 days in an acute private hospital in Australia.

Methods
An interpretative qualitative study was conducted. Semi-structured interviews with 8 bereaved relatives whose family member had died at an acute private hospital shared their experiences of the EoL care during the last 3 days of life. The transcribed interviews were analyzed using inductive thematic analysis.

Results
Bereaved family members had mixed experiences, and their primary concerns related to the need for improvements in support for the family; communication; and clinicians partnering with families. The need for family support encompassed care for the person dying and the bereaved relatives, before and during the last days of life, and after death. Bereaved relatives perceived that hospital based EoL care could be positive when the care was collaborative with health professionals, patients, and relatives and there was effective communication.

Significance of results
A patient- and family-centered approach to EoL care should be provided in hospitals, and it requires understanding of the needs of both patients and family members, including informational requirements, communication approaches, and care delivery. Health-care organizations have a responsibility to care for families and this must be considered as part of organizational readiness and ongoing assessment to determine if the standards for EoL care are met. The findings serve as a guide for evidence-informed practice and may contribute to the development of resources and guidelines for delivery of quality EoL care.
Exploring palliative and end-of-life care perspectives and lived experiences among generations of African migrants residing outside the continent: A scoping review

Published: February 2025

Abstract

Objectives
This review aimed to chart existing literature and identify gaps in the evidence base concerning palliative and end-of-life care perspectives and experiences among different generations of African migrants residing outside the continent.

Methods
This review adhered to a predefined protocol, utilizing the Arksey and O’Malley 5-stage framework, as refined by Danielle Levac and colleagues. A systematic search of 5 bibliographic databases (from inception to December 2022) yielded 79 published studies. After title, abstract, and full-text screening using Covidence®, 7 studies met the inclusion criteria. Data extraction was guided by a conceptual framework tailored to the research topic and questions, with results presented in the narrative form.

Results
Cultural and religious beliefs and practices significantly shaped African migrants’ perspectives on end-of-life care. A nuanced boundary between palliative and curative care emerged, with the former often stigmatized and stereotypically associated with death and dying. Common barriers to accessing end-of-life care included limited awareness, low literacy, and perceived inadequacy of culturally sensitive care, resulting in disparities in both access and outcomes. Additionally, reluctance to discuss death and dying, along with mistrust of Western healthcare systems, constituted significant obstacles. The studies underscored the necessity of enhancing provider–patient communication by engaging with migrants to raise awareness of services and fostering inclusive healthcare environments for improved care outcomes.

Significance of results
Existing research on racial and ethnic disparities underscores the unequal quality and outcomes of end-of-life care across various racial groups. However, there is still insufficient understanding of these diverse end-of-life care needs, particularly in host countries. Bridging this knowledge gap is crucial for reducing health disparities and enhancing the delivery of culturally sensitive care within Western healthcare systems.

Abstract
Ionic fluidic devices are gaining interest due to their role in enabling self-powered neuromorphic computing systems. In this study, we present an approach that integrates an iontronic fluidic memristive (IFM) device with low input impedance and a triboelectric nanogenerator (TENG) based on ferrofluid (FF), which has high input impedance. By incorporating contact separation electromagnetic (EMG) signals with low input impedance into our FF TENG device, we enhance the FF TENG’s performance by increasing energy harvesting, thereby enabling the autonomous powering of IFM devices for self-powered computing. Further, replicating neuronal activities using artificial iontronic fluidic systems is key to advancing neuromorphic computing. These fluidic devices, composed of soft-matter materials, dynamically adjust their conductance by altering the solution interface. We developed voltage-controlled memristor and memcapacitor memory in polydimethylsiloxane (PDMS) structures, utilising a fluidic interface of FF and polyacrylic acid partial sodium salt (PAA Na+). The confined ion interactions in this system induce hysteresis in ion transport across various frequencies, resulting in significant ion memory effects. Our IFM successfully replicates diverse electric pulse patterns, making it highly suitable for neuromorphic computing. Furthermore, our system demonstrates synapse-like learning functions, storing and retrieving short-term (STM) and long-term memory (LTM). The fluidic memristor exhibits dynamic synapse-like features, making it a promising candidate for the hardware implementation of neural networks. FF TENG/EMG device adaptability and seamless integration with biological systems enable the development of advanced neuromorphic devices using iontronic fluidic materials, further enhanced by intricate chemical designs for self-powered electronics.

Abstract
Excessive inflammation and cytokine release are hallmarks of severe COVID-19. Certain programmed cell death processes can drive inflammation, however, their role in the pathogenesis of severe COVID-19 is unclear. Pyroptosis is a pro-inflammatory form of regulated cell death initiated by inflammasomes and executed by the pore-forming protein gasdermin D (GSDMD). Using an established mouse adapted SARS-CoV-2 virus and a panel of gene-targeted mice we found that deletion of the inflammasome (NLRP1/3 and the adaptor ASC) and pore forming proteins involved in pyroptosis (GSDMA/C/D/E) only marginally reduced IL-1β levels and did not impact disease outcome or viral loads. Furthermore, we found that SARS-CoV-2 infection did not trigger GSDMD activation in mouse lungs. Finally, we did not observe any difference between WT animals and mice with compound deficiencies in the pro-inflammatory initiator caspases (C1/11/12

−/−
). This indicates that the classical canonical and non-canonical pro-inflammatory caspases known to process and activate pro-IL-1β, pro-IL-18 and GSDMD do not substantially contribute to SARS-CoV-2 pathogenesis. However, the loss of IL-1β, but not the absence of IL-18, ameliorated disease and enhanced survival in SARS-CoV-2 infected animals compared to wildtype mice. Collectively, these findings demonstrate that IL-1β is an important factor contributing to severe SARS-CoV-2 disease, but its release was largely independent of inflammasome and pyroptotic pathways.

Abstract
Vanadium-dependent haloperoxidases (VHPOs) are biotechnologically valuable and operationally versatile biocatalysts. VHPOs share remarkable active-site structural similarities yet display variable reactivity and selectivity. The factors dictating substrate specificity and, thus, a general understanding of VHPO reaction control still need to be discovered. This work’s strategic single-point mutation in the cyanobacterial bromoperoxidase AmVHPO facilitates a selectivity switch to allow aryl chlorination. This mutation induces loop formation that interacts with the neighboring protein monomer, creating a tunnel to the active sites. Structural analysis of the substrate-R425S-mutant complex reveals a substrate-binding site at the interface of two adjacent units. There, residues Glu139 and Phe401 interact with arenes, extending the substrate residence time close to the vanadate cofactor and stabilizing intermediates. Our findings validate the long-debated existence of direct substrate binding and provide a detailed VHPO mechanistic understanding. This work will pave the way for a broader application of VHPOs in diverse chemical processes.

Abstract
HIV-1 latency is mainly characterized at transcriptional level, and little is known about post-transcriptional mechanisms and their contribution to reactivation. The viral protein Rev controls the nucleocytoplasmic export of unspliced and singly-spliced RNA that is central to proviral replication-competence and is therefore a prerequisite for efficient viral reactivation during the “shock-and-kill” cure therapy. Here we show that during infection and reactivation, unspliced HIV-1 RNA is a subject to complex and dynamic regulation by the Rev cofactor MATR3 and the MTR4 cofactor of the nuclear exosome. MATR3 and MTR4 coexist in the same ribonucleoprotein complex functioning to either maintain or degrade the RNA, respectively, with Rev orchestrating this regulatory switch. Moreover, we provide evidence of nuclear retention of unspliced HIV-1 RNA in ex vivo cultures from 22 ART-treated people with HIV, highlighting a reversible post-transcriptional block to viral RNA nucleocytoplasmic export that is relevant to the design of curative interventions.
Towards a World Wide Web powered by generative AI

Published: February 2025

Abstract
Generative Artificial Intelligence (AI) is a cutting-edge technology capable of producing text, images, and various media content leveraging generative models and user prompts. Between 2022 and 2023, generative AI surged in popularity with a plethora of applications spanning from AI-powered movies to chatbots. This paper investigates the potential of generative AI within the realm of the World Wide Web, specifically focusing on image generation. Web developers already harness generative AI to help craft text and images, while Web browsers might use it in the future to locally generate images for tasks such as repairing broken webpages, conserving bandwidth, and enhancing privacy. To explore this research area, this paper developed WebDiffusion, a tool that allows to simulate a Web powered by stable diffusion, a popular text-to-image model, from both a client and server perspective. Such a tool is the first of its kind, paving the way towards a futuristic world wide web where web images can be created using generative AI. WebDiffusion further supports crowdsourcing of user opinions, which is used to evaluate the quality and accuracy of 409 AI-generated images sourced from 60 webpages. Our findings suggest that generative AI is already capable of producing pertinent and high-quality Web images, even without requiring Web designers to manually input prompts, just by leveraging contextual information available within the webpages. However, direct in-browser image generation remains a challenge, as only highly powerful GPUs, such as the A40 and A100, can (partially) compete with classic image downloads. Nevertheless, this approach could be valuable for a subset of the images, for example, when fixing broken webpages or handling highly private content.

Abstract
Soft-shelled turtles, or Trionychia, are an enigmatic and fascinating group due to their specific morphological features and ecological adaptations. Based on mitochondrial DNA (mtDNA) and/or nuclear markers, previous studies showed the incongruent phylogenetic topologies within Trionychia (e.g., the Palea and its closely related species). In order to resolve the equivocal relationships and obtain some “genome-level” common evolutionary characters of soft-shelled turtles, in this study, we assembled and annotated the complete mitochondrial genomes of Palea steindachneri and Pelodiscus axenaria, both naturally distributed in Asia. The sizes of the two mitochondrial genomes were 16,811 bp and 17,143 bp, respectively. Typical vertebrate animal mtDNA features were observed, such as the usual gene components and arrangements (37 genes with a non-coding control region) and the A + T biased nucleotide compositions on the light strand (61.5% and 62.7%, respectively). All conserved blocks common to the vertebrates control region except for the extended terminal associated sequences (ETAS2) were found in the two soft-shelled turtles. The ω ratio averaged over all sites of each protein-coding gene (PCG) was below 1, which indicated purifying selection at the gene-wide level. However, a positive selection site at the 350-codon position in the cytb gene was detected, as estimated by Bayes empirical Bayes (BEB) analysis. Compared with the gene subsets, the mitogenomes provided the most robust phylogenetic resolution. The monophyly of the clades Amydona, Gigantaesuarochelys, and Apalonia was well supported. Topology discrepancies were observed among different datasets (e.g., the positions of Lissemys and Palea), reflecting the heterogeneous phylogenetic signals in the soft-shelled turtle mitogenomes. Precise date estimation based on Bayesian relaxed clock analyses indicated that the crown group age of extant Trionychia was approximately 115.84 Ma (95% HPD: 91.33–142.18 Ma). Paleoclimate changes, especially the Eocene − Oligocene transition, could be responsible for the speciation in these groups. Our results reiterated the necessity and effectiveness of incorporating entire mitochondrial genomes to delineate phylogenetic relationships in chelonian phylogeny studies.
Spatial distribution and functional integration of displaced retinal ganglion cells

Published: February 2025

Abstract
The retina contains distinct types of ganglion cells, which form mosaics with cells of each type at each position of the visual field. Displaced retinal ganglion cells (dRGCs) occur with cell bodies in the inner nuclear layer (INL), and regularly placed RGCs with cell bodies in the ganglion cell layer. An example of mammalian dRGCs are M1-type intrinsically photosensitive ganglion cells (ipRGCs). Little is known, however, about their relationship with regularly placed ipRGCs. We identified mouse ipRGC types M1, M2, and M4/sONɑ by immunohistochemistry and light microscopy. Reconstruction of immunolabeled mosaics from M1 and sONɑ RGCs indicated that dRGCs tiled the retina with their regular RGC partners. Multi-electrode array recordings revealed conventional receptive fields of displaced sONɑ RGCs which fit into the mosaic of their regular counterparts. An RGC distribution analysis showed type-specific dRGC patterns which followed neither the global density distribution of all RGCs nor the local densities of corresponding cell types. The displacement of RGC bodies into the INL occurs in a type-dependent manner, where dRGCs are positioned to form complete mosaics with their regular partners. Our data suggest that dRGCs and regular RGCs serve the same functional role within their corresponding population of RGCs.
Acute and chronic gene expression activation following medial forebrain bundle DBS and selective dopamine pathway stimulation

Published: February 2025

Abstract
Deep brain stimulation (DBS) of the medial forebrain bundle (mfb) demonstrated anti-depressant effects both clinically and experimentally. Modulation of mesocorticolimbic dopaminergic (DA) activity could contribute—in part—to the therapeutic effects. By comparing selective and pathway specific midbrain DA optogenetic stimulation with the global, non-pathway specific mfb-DBS, the study explored changes in gene-expression of key biomarkers associated with neurocircuitry of depression. Rats received either optogenetic DAergic or mfb-DBS, delivered as acute/single or chronic/repeated stimulation. Micro-dissected regions were prepared for in situ hybridization targeting biomarkers of GABAergic, glutamatergic, and dopaminergic systems. Mfb-DBS mediated DA independent pathway increased GABAergic biomarkers (GABAA, GAD1) in frontal and accumbal regions, not in midbrain. The combinations of low frequency/high pulse width and high frequency/low pulse width stimulation generally increased biomarker expression similarly, but chronic/repetitive stimulation had no accumulative effect. Interestingly, unilateral stimulation had bilateral effects, but stimulation modalities had little impact on DAT and Vglut2 expression. In conclusion, both low and high frequency, acute/single and chronic/repetitive mfb-DBS—but not selective optogenetic stimulation -activated gene expression of biomarkers associated with GABAergic transmission. The increased expression was transitory and less chronic than predicted. Importantly, the study provides evidence that the anti-depressant therapeutic effects of clinical medial forebrain bundle DBS occurs—in part—be via modulation of GABAergic signalling which in turn could regulate the release of dopamine in frontal and accumbal regions. In addition, clinical implication of the data is that unilateral stimulation had bilateral consequences on the gene expression, although the physiological and functional sequelae of this are yet unknown.
Feasibility and efficacy of the forced oscillation technique in patients with lysosomal storage diseases

Abstract
Lysosomal storage disorders (LSDs) are a diverse group of inborn errors of metabolism, which involves the storage of macromolecules within the lysosome due to the absence of or deficiency in lysosomal enzymes. In this condition, respiratory dysfunction is the common cause of morbidity and mortality. Thus, an objective measurement examination of pulmonary function, such as spirometry, is essential for the diagnosis and management of respiratory conditions. However, spirometry requires active patient involvement. Meanwhile, the forced oscillation technique (FOT) is performed during tidal breathing and is feasible in patients who cannot perform spirometry. Thus, the current study aimed to assess the feasibility and efficacy of FOT in assessing respiratory function among patients with LSD. This study was conducted at the outpatient department of Tawam Hospital, Al-Ain, the United Arab Emirates. Patients with confirmed LSD were included in the analysis. Information on respiratory history was obtained using a standardized respiratory questionnaire, and lung function was assessed using FOT. The main outcomes were respiratory resistance (Rrs5), reactance at 5 Hz (Xrs5), and area under the reactance curve (AX). In total, 35 patients with LSD were assessed. FOT was used to evaluate 16 (47%) patients. Of the patients who were successfully assessed using FOT, 10 presented with abnormal outcomes. Hence, there was an association between lung function assessed using FOT and spirometry results in these patients. FOT can help obtain lung function measurements in patients with LSD. In this study, the patients commonly presented with abnormal FOT outcomes.
