A systematic review suggests extension and redefinition of a food-deception pollination syndrome involving anautogenous flies.

Background And Aims: The currently recognized diversity of pollination strategies requires pollination syndromes to be updated. Described a decade ago, kleptomyiophily is a deceptive pollination system in which plants exploit the nutrient-seeking behavior of females of kleptoparasitic flies (Chloropidae and Milichiidae) by olfactorily mimicking their insect host. Such a pollination system was already hypothesized for pollination by biting midges (Ceratopogonidae) but has never been formalized.

Modeling impairment of ionic regulation with extended Adaptive Exponential integrate-and-fire models.

To model the dynamics of neuron membrane excitability many models can be considered, from the most biophysically detailed to the highest level of phenomenological description. Recent works at the single neuron level have shown the importance of taking into account the evolution of slow variables such as ionic concentration. A reduction of such a model to models of the integrate-and-fire family is interesting to then go to large network models.

Assessing time series correlation significance: A parametric approach with application to physiological signals.

Correlation coefficients play a pivotal role in quantifying linear relationships between random variables. Yet, their application to time series data is very challenging due to temporal dependencies. This paper introduces a novel approach to estimate the statistical significance of correlation coefficients in time series data, addressing the limitations of traditional methods based on the concept of effective degrees of freedom (or effective sample size, ESS).

One Health Field Approach Applied to Leptospirosis: A Systematic Review and Meta-Analysis Across Humans, Animals and the Environment.

Background: Leptospirosis is a neglected zoonosis transmitted through urine of infected hosts or contaminated environments. The transmission of bacteria between humans, animals, and the environment underscores the necessity of a One Health approach.

Methods: We conducted a systematic review to identify significant findings and challenges in One Health research on leptospirosis, focusing on studies involving sampling in ≥2 of the 3 compartments: human, animal, and environment.

Association of poultry vaccination with interspecies transmission and molecular evolution of H5 subtype avian influenza virus.

The effectiveness of poultry vaccination in preventing the transmission of highly pathogenic avian influenza viruses (AIVs) has been debated, and its impact on wild birds remains uncertain. Here, we reconstruct the movements of H5 subtype AIV lineages among vaccinated poultry, unvaccinated poultry, and wild birds, worldwide, from 1996 to 2023. We find that there is a time lag in viral transmission among different host populations and that movements from wild birds to unvaccinated poultry were more frequent than those from wild birds to vaccinated poultry.

Translation of the downstream ORF from bicistronic mRNAs by human cells: Impact of codon usage and splicing in the upstream ORF.

Biochemistry textbooks describe eukaryotic mRNAs as monocistronic. However, increasing evidence reveals the widespread presence and translation of upstream open reading frames preceding the "main" ORF. DNA and RNA viruses infecting eukaryotes often produce polycistronic mRNAs and viruses have evolved multiple ways of manipulating the host's translation machinery.

Designing a multi-epitope vaccine candidate against human rhinovirus C utilizing immunoinformatics approach.

Human rhinovirus C (HRV-C) is a significant contributor to respiratory tract infections in children and is implicated in asthma exacerbations across all age groups. Despite its impact, there is currently no licensed vaccine available for HRV-C. Here, we present a novel approach to address this gap by employing immunoinformatics techniques for the design of a multi-epitope-based vaccine against HRV-C.

Temporal and regional X-linked gene reactivation in the mouse germline reveals site-specific retention of epigenetic silencing.

Random X-chromosome inactivation is a hallmark of female mammalian somatic cells. This epigenetic mechanism, mediated by the long noncoding RNA Xist, occurs in the early embryo and is stably maintained throughout life, although inactivation is lost during primordial germ cell (PGC) development. Using a combination of single-cell allele-specific RNA sequencing and low-input chromatin profiling on developing mouse PGCs, we provide a detailed map of X-linked gene reactivation.

Insights into Calcium Phosphate Formation Induced by the Dissolution of 45S5 Bioactive Glass.

Although models have been proposed to explain the mechanisms of bioglass (BG) dissolution and subsequent calcium phosphate (CaP) mineralization, open questions remain. The processes in which phase transition occurs in aqueous solutions and their dynamics remain underexplored partly because traditional instruments/techniques do not allow for direct observations at the adequate time and length scales at which such phase transformations occur. For instance, given the crucial role of the silica gel in CaP formation during BG dissolution, uncertainty exists about how such a silica gel forms on the BG surface.

Cathepsins: Novel opportunities for antibody therapeutics in cancer.

Cathepsins, the most abundant lysosomal proteases, have key functions in cell maintenance and homeostasis. They are overexpressed and hypersecreted in cancer and associated with poor prognosis. Secreted cathepsins display pro-tumour activities in the tumour microenvironment and thus represent interesting molecular targets in oncology.

Designing of an innovative conserved multiepitope subunit vaccine targeting SARS-CoV-2 glycoprotein and nucleoprotein through immunoinformatic.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has imposed substantial challenges on our society due to the COVID-19 pandemic. This virus relies heavily on its surface glycoprotein (S-glycoprotein) to facilitate attachment, fusion, and entry into host cells. While the nucleoprotein (N) in the ribonucleoprotein core binds to the viral RNA genome.

Is provisioning rate of parents and helpers influenced by the simulated presence of novel individuals?

Abstract: Cooperative behaviour is widespread in animals and is likely to be the result of multiple selective pressures. A contentious hypothesis is that helping enhances the probability of obtaining a sexual partner (i.e.

Potential antihyperlipidemic effects of myrcenol and curzerene in high-fat fed rats.

The study evaluated the anti-hyperlipidemic effects of myrcenol and curzerene on a high fat diet induced hyperlipidemia rat model. Thirty male albino rats were fed on a high-fat diet for four months. The HFD-induced hyperperlipidemia rats were treated with rosuvastatin (10 mg/kg), curzerene (130 mg/kg) and myrcenol (100 mg/kg) for four weeks.

Homologous In-Radiolabeled Platelet Survival and Sequestration Exploration for Refractory Immunologic Thrombocytopenic purpura in Children: A Strategy to Avoid Unnecessary Splenectomy.

Immunologic thrombocytopenic purpura (ITP) is a condition that affects four to 18 per 100 000 children every year. In most cases, spontaneous remission occurs, but splenectomy may be proposed. Exploring the site of platelet sequestration can help to better predict potential poor responders to splenectomy, but In-radiolabeled platelet scintigraphy (IPS) can be difficult to perform in children with very few platelets.

Left atrial reservoir strain as a predictor of cardiac dysfunction in a murine model of pressure overload.

Aim: Left atrial (LA) strain is emerging as a valuable metric for evaluating cardiac function, particularly under pathological conditions such as pressure overload. This preclinical study investigates the predictive utility of LA strain on cardiac function in a murine model subjected to pressure overload, mimicking pathologies such as hypertension and aortic stenosis.

Methods: High-resolution ultrasound was performed in a cohort of mice (n = 16) to evaluate left atrial and left ventricular function at baseline and 2 and 4 weeks after transverse aortic constriction (TAC).

Recommendations for mitochondria transfer and transplantation nomenclature and characterization.

Intercellular mitochondria transfer is an evolutionarily conserved process in which one cell delivers some of their mitochondria to another cell in the absence of cell division. This process has diverse functions depending on the cell types involved and physiological or disease context. Although mitochondria transfer was first shown to provide metabolic support to acceptor cells, recent studies have revealed diverse functions of mitochondria transfer, including, but not limited to, the maintenance of mitochondria quality of the donor cell and the regulation of tissue homeostasis and remodelling.

Spatio-temporal risk prediction of leptospirosis: A machine-learning-based approach.

Background: Leptospirosis is a neglected zoonotic disease prevalent worldwide, particularly in tropical regions experiencing frequent rainfall and severe cyclones, which are further aggravated by climate change. This bacterial zoonosis, caused by the Leptospira genus, can be transmitted through contaminated water and soil. The Pacific islands bear a high burden of leptospirosis, making it crucial to identify key factors influencing its distribution.

Loneliness and biomarkers of Alzheimer's disease, axonal damage, and astrogliosis: A coordinated analysis of two longitudinal cohorts.

Objectives: Loneliness is associated with an elevated risk of dementia. There is mixed evidence from imaging studies on whether loneliness is associated with neuropathology in dementia-free adults. This study tests whether loneliness is associated with plasma neurobiomarkers of amyloid (Aβ42/Aβ40), phosphorylated tau 181 (pTau181), neurofilament light chain (NfL), and glial fibrillary acidic protein (GFAP) and imaging measures of amyloid and tau.

Clustering and drivers of symptoms observed at week six after antidepressant treatment in depressed outpatients.

Background: Depressive symptoms remaining after antidepressant treatment increase the risk of relapse and recurrence. We aimed to analyze the distribution and main drivers of remaining symptoms in patients with a major depressive episode.

Methods: Two independent samples of 8,229 and 5,926 patients from two large naturalistic studies were retrospectively analyzed.

Epidemiology of Major Amputation Following Diabetic Foot Ulcer: Insights from Recent Nationwide Data in the French National Health Registry (SNDS).

Objective: The out-of-hospital care pathways of people with DFU have been little studied. We used the French National Health Data System (SNDS) to collect refund and care pathway data for all French residents. The aim of this study was to determine the incidence of major lower limb amputation (MA) and associated risk factors in a population with an incident DFU.
