Transcriptomic and Biochemical analysis of Procambarus clarkii upon exposure to Pesticides: Population-Specific responses as a sign of pollutant resistance?

The effects that anthropogenic stressors may have on modulating species' plasticity has been relatively unexplored; however, it represents a scientific frontier that may offer insights into their ability to colonize new habitats. To explore the advantage that inhabiting polluted environments may offer to invasive species, we selected the crayfish Procambarus clarkii, a species that can colonize and thrive in a wide range of aquatic environments, including heavily polluted ones. Here, we studied the molecular and physiological responses of crayfish when experimentally exposed to a pesticide mix of azoxystrobin and oxadiazon at sublethal concentrations.

PREDICTIVE MODELS OF CLINICAL OUTCOME OF ENDOVASCULAR TREATMENT FOR ANTERIOR CIRCULATION STROKE USING MACHINE LEARNING.

Background And Purpose: Mechanical Thrombectomy (MT) has recently become the standard of care for anterior circulation stroke with large vessel occlusion, but predictive factors of successful MT are still not clearly defined. To tailor treatment individually for each patient, the aim of this study was to evaluate the performances of Machine Learning to predict clinical outcome (mRS) at 3 months after MT.

Material And Methods: From the ETIS French prospective multicenter registry, data from patients who underwent MT for anterior circulation stroke with large vessel occlusion between January 2018 and December 2020 were extracted.

Our objective is to accurately assess the impact of regulation on the availability of cardiovascular MDs in healthcare facilities. High-risk cardiovascular MDs appear to be heavily impacted by the regulation, with reclassification leading to mandatory clinical investigations.

Sibling similarity in telomere length in Adélie penguin chicks.

Early life telomere length is thought to influence and predict an individual's fitness. It has been shown to vary significantly in early life compared to adulthood. Investigating the factors influencing telomere length in young individuals is therefore of particular interest, especially as the relative importance of heredity compared to post-natal conditions remains largely uncertain.

Cold and longevity: Can cold exposure counteract aging?

Aging is a multifaceted biological process characterized by a progressive decline in physiological functions and heightened vulnerability to diseases, shaped by genetic, environmental, and lifestyle factors. Among these, cold exposure has garnered interest for its potential anti-aging benefits. This review examines the impact of cold exposure on aging, focusing on key physiological processes such as inflammation, oxidative stress, metabolic regulation, and cardiovascular health.

Epidemiology and outcomes associated with MBL-producing Enterobacterales: A systematic literature review.

The increasing prevalence of infections due to metallo-β-lactamase (MBL)-producing Enterobacterales poses a serious concern given the limited treatment options available. This systematic literature review (SLR) describes the molecular epidemiology, geographical distribution, and clinical outcomes of such infections. Systematic searches of literature published between January 2013 and May 2023 were performed, and 39 studies with an MBL sample size of ≥25 isolates and ≥2 well-defined outcomes were eligible.

P2 purinergic receptors at the heart of pathological left ventricular remodeling following acute myocardial infarction.

Pathological left ventricular remodeling is a complex process following an acute myocardial infarction, leading to architectural disorganization of the cardiac tissue. This phenomenon is characterized by sterile inflammation and the exaggerated development of fibrotic tissue, which is non-contractile and poorly conductive, responsible for organ dysfunction and heart failure. At present, specific therapies are lacking for both prevention and treatment of this condition, and no biomarkers are currently validated to identify at-risk patients.

Dyadic adjustment of persons with albinism and their significant other: A Bayesian mediation model of the Actor-Partner Interdependence (APIMeM).

Background: Limited standardized empirical research exists in France on the psychosocial implications of albinism, prompting an investigation into how affected persons adapt to their disabilities. Recent advancements in health psychology have led researchers to adopt a systemic approach, considering disabilities and involving close relatives in the adaptation process. The aim of this study was to explore the mediating role of dyadic coping within family dyads, where one is a person with albinism (PWA) and the other is a close relative.

One-year data from the ongoing BeyoND study (NCT02726386) showed that the ND0612 regimen was safe and well tolerated and provided a sustained ≥2-h improvement in daily Good ON-time through 12 months of treatment.

Methods: We describe 3-year safety and efficacy outcomes for participants who completed 12 months of ND0612 treatment in the core study period and entered the extension phase.

To what extent does status epilepticus contribute to brain damage in the developmental and epileptic Encephalopathies.

This paper is based on a presentation made at the 9th London-Innsbruck Colloquium on Status Epilepticus and Acute Seizures in April 2024. Status Epilepticus (SE) is a neurological emergency involving prolonged seizures that disrupt brain function and may cause severe, long-term neurological damage. Developmental and Epileptic Encephalopathies (DEEs), a group of severe genetic disorders with early-onset epilepsy, often exhibit SE episodes that compound their inherent cognitive and developmental challenges.

Detection and correction of translational motion in SPECT with exponential data consistency conditions.

Rigid patient motion can cause artifacts in single photon emission computed tomography (SPECT) images, compromising the diagnosis and treatment planning. Exponential data consistency conditions (eDCCs) are mathematical equations describing the redundancy of exponential SPECT measurements. It has been recently shown that eDCCs can be used to detect patient motion in SPECT projections.

Increasing the resolution of malaria early warning systems for use by local health actors.

Background: The increasing availability of electronic health system data and remotely-sensed environmental variables has led to the emergence of statistical models capable of producing malaria forecasts. Many of these models have been operationalized into malaria early warning systems (MEWSs), which provide predictions of malaria dynamics several months in advance at national and regional levels. However, MEWSs rarely produce predictions at the village-level, the operational scale of community health systems and the first point of contact for the majority of rural populations in malaria-endemic countries.

Poor efficacy of the combination of clarithromycin, amikacin, and cefoxitin against Mycobacterium abscessus in the hollow fiber infection model.

Background: Mycobacterium abscessus (MABS) causes difficult-to-treat pulmonary and extra-pulmonary infections. A combination therapy comprising amikacin, cefoxitin, and a macrolide agent is recommended, but its antimicrobial activity and clinical efficacy is uncertain. Inducible resistance to macrolides (macrolides-iR) has been associated with poor clinical response in pulmonary infections, whilst for extra-pulmonary infections data are scarce.

Induction by caterpillars of stored and emitted volatiles in terpene chemotypes from populations of wild cotton (Gossypium hirsutum).

Background: Upland cotton (Gossypium hirsutum) plants constitutively store volatile terpenes in their leaves, which are steadily emitted at low levels. Herbivory leads to a greater release of these stored volatiles. Additionally, damaged plants increase the accumulation of volatile terpenes in their leaves and begin to synthesize and emit other terpenes and additional compounds.

How and why small volcanic ocean islands collapse and move vertically up and down.

Mass controls two major processes in volcanic islands: large-scale collapse and vertical movements. Therefore, large islands like Hawaii are gradually subsiding and have undergone massive landsliding. What if the mass is much smaller, and there is good evidence that the vertical movement is more complex than simple loading-related subsidence? Here, we show that small volcanic islands, seemingly stable because of the small mass, can undergo sector collapses that can affect the vertical movement of the island.

Modelling the seasonal dynamics of Aedes albopictus populations using a spatio-temporal stacked machine learning model.

Various modelling techniques are available to understand the temporal and spatial variations of the phenology of species. Scientists often rely on correlative models, which establish a statistical relationship between a response variable (such as species abundance or presence-absence) and a set of predominantly abiotic covariates. The choice of the modeling approach, i.

High-Yield Cellulose Nanocrystals from Bleached Eucalyptus Fibers via Maleic Acid Hydrothermal Treatment and High-Pressure Homogenization.

This study reports the preparation of cellulose nanocrystals (CNCs) from commercial bleached eucalyptus Kraft pulp (BEKP) using a hydrothermal treatment in the presence of maleic acid (MA), followed by high-pressure homogenization. Compared with conventional hydrolysis methods, this approach offers significant advantages, including lower acid concentration, higher yield, and milder processing conditions. CNCs were produced with a high yield (70-85 wt %) by high-pressure homogenization of hydrothermally treated BEKP fibers with 10-20 wt % maleic acid at 150 °C, giving rise to a stable translucent gel of CNCs with a rod-like morphology (200-400 nm length and 10-40 nm width).

Probing spin-electric transitions in a molecular exchange qubit.

Electric fields represent an ideal means for controlling spins at the nanoscale and, more specifically, for manipulating protected degrees of freedom in multispin systems. Here we perform low-temperature magnetic far-IR spectroscopy on a molecular spin triangle (Fe) and provide initial experimental evidence suggesting spin-electric transitions in polynuclear complexes. The co-presence of electric- and magnetic-dipole transitions, allows us to estimate the spin-electric coupling.

Cell adhesion and spreading on fluid membranes through microtubules-dependent mechanotransduction.

Integrin clusters facilitate mechanical force transmission (mechanotransduction) and regulate biochemical signaling during cell adhesion. However, most studies have focused on rigid substrates. On fluid substrates like supported lipid bilayers (SLBs), integrin ligands are mobile, and adhesive complexes are traditionally thought unable to anchor for cell spreading.
