Cockpit automation has brought significant benefits in terms of mental workload and fatigue. However, the way primary flight instruments are monitored by pilots may be negatively affected by the high confidence in systems. We examined the effects of automation level on mental workload, manual flight performance and visual strategies.

Rab7A has a key role in regulating membrane trafficking at late endosomes. By interacting with several different effectors, this small GTPase controls late endosome mobility, orchestrates fusion events between late endosomes and lysosomes, and participates in the formation of and regulates the fusion between autophagosomes and lysosomes. Rab7A is also responsible for the spatiotemporal recruitment of retromer, which is required for the endosome-to-trans-Golgi network retrieval of cargo receptors such as sortilin (SORT1) and CI-MPR (also known as IGF2R).

Widespread pesticide use for decades has caused environmental damage, biodiversity loss, serious human and animal health problems, and resistance to insecticides. Innovative strategies are needed to reduce treatment doses in pest management and to overcome insecticide resistance. In the present study, combinations of indoxacarb, an oxadiazine insecticide, with sublethal concentrations of deltamethrin encapsulated in lipid nanocapsules, have been tested on the crop pest .

During embryogenesis, cells arrange into precise patterns that enable tissues and organs to develop specialized functions. Despite its critical importance, the molecular choreography behind these collective cellular behaviors remains elusive, posing a major challenge in developmental biology and limiting advances in regenerative medicine. By using the mouse hair follicle as a mini-organ system to study the formation of bud-like structures during embryonic development, our work uncovers a crucial role for the Rho GTPase regulator ARHGEF3 in hair follicle morphogenesis.

The Water Framework Directive (WFD) requires member states to routinely assess the river ecological status using community-based indices. However, there is still a lack of published WFD-compliant methods for the French West Indies, especially using diatom-based indices. Martinique and Guadeloupe exhibit diverse landscapes shaped by their complex geological history and tropical climatic conditions.

  • - Interventions for children's eco-anxiety emphasize promoting hope but often overlook the importance of allowing kids to express their feelings of despair about climate change.
  • - Children need a safe space to explore their emotions regarding the climate crisis, including feelings of fear and sadness.
  • - Adults play a crucial role by recognizing and openly discussing these emotions with children, helping them process their feelings more effectively.

  • The modified Mallampati classification is used to assess the risk of airway complications before surgery, but there may be inconsistencies in how it's evaluated, affecting its diagnostic accuracy.
  • In a study involving adult patients, researchers compared the traditional modified Mallampati score with a newer "best visible" score to predict difficult intubations, finding that the best visible score had lower sensitivity but higher specificity.
  • The results suggest that the best visible Mallampati score may misclassify many patients at risk for difficult intubation, highlighting the need for caution in using it as a predictor compared to the modified version.

Aim Of The Study: Emergency resuscitative thoracotomy (ERT) has been described as a potentially life-saving procedure for trauma patients who have been admitted in refractory shock or with recent loss of sign of life (SOL). This nationwide registry analysis aimed to describe the French practice of ERT.

Patients And Methods: From 2015 to 2021, all severe trauma patients who underwent ERT were extracted from the TraumaBase→ registry.

  • - During summer 2023, Europe saw a small uptick in mpox cases after a major outbreak in 2022, marked by peaks happening at different times in various countries!* - The demographic makeup of the new cases was similar to those from previous reports, maintaining the same trends.
  • - All collected case sequences from this recent resurgence belonged to clade IIb, highlighting the need for ongoing control efforts to eliminate mpox in the region.

  • Invasive meningococcal disease (IMD) is a serious illness caused by the bacterium Neisseria meningitidis, often leading to meningitis or septicemia.
  • There are six main serogroups (A, B, C, W, X, Y) responsible for the majority of cases, which can spread through respiratory droplets and secretions from infected individuals or carriers.
  • Vaccination is available to prevent IMD, and giving antibiotics to close contacts of infected people is vital to stop further infections.

Organic UV filters are emerging contaminants in personal care products such as sunscreens. The toxicity of numerous of these UV filter compounds has been demonstrated in several marine taxa. However, whilst the biological impact has already been largely demonstrated, the anthropogenic drivers leading to UV filter contamination still need to be identified.

The thermal Hall effect has emerged as a potential probe of exotic excitations in spin liquids. In the Kitaev magnet -RuCl, the thermal Hall conductivity has been attributed to Majorana fermions, chiral magnons, or phonons. Theoretically, the former two types of heat carriers can generate a "planar" , whereby the magnetic field is parallel to the heat current, but it is unknown whether phonons also could.

  • The study evaluated the management practices for stage III non-small-cell lung cancer (NSCLC) across 41 medical centers in France between 2020 and 2022, focusing on diagnostic and treatment methods.
  • Results indicated that standard imaging techniques were widely used, but invasive staging procedures were underperformed despite a high incidence of node involvement.
  • The findings showed that treatment generally adhered to clinical guidelines, though a notable gap in the frequency of invasive staging was identified.

Purpose: To improve the quality of care for patients with breast cancer, an analysis of the health-care pathway, considering feedback from both health-care practitioners (HCPs) and patients, is needed.

Methods: Between 2020 and 2022, we conducted a survey at French breast cancer centers and analyzed information from questionnaires completed by HCPs and patients. We collected information on center organization, diagnostic processes, treatment decisions and modalities, supportive care, patient advocacy groups, and work issues.

Cystic fibrosis (CF) is caused by mutations in the CF transmembrane conductance regulator (CFTR) protein. This epithelial anion channel regulates the active transport of chloride and bicarbonate ions across membranes. Mutations result in reduced surface expression of CFTR channels with impaired functionality.

Building expertise in climate and planetary health among healthcare professionals cannot come with greater urgency as the threats from climate change become increasingly apparent. Current and future healthcare professionals-particularly internists-will increasingly need to understand the interconnectedness of natural systems and human health to better serve their patients longitudinally. Despite this, few national medical societies and accreditation bodies espouse frameworks for climate change and planetary health-related education at the undergraduate (UME), graduate (GME), and continuing (CME) medical education level.

Marine heatwaves (MHW) threaten marine organisms and tend to increase in frequency and intensity. We exposed the blue mussel Mytilus edulis to a MHW lasting 23 days, including two 10-d periods of thermal intensity increase of +5 °C (20 °C-25 °C) interspersed by 1 day back to 20 °C, followed by a 4-d recovery period. We investigated behaviour responses of mussels and gene expression changes relative to the circadian rhythm (Per), oxidative stress (SOD), cellular apoptosis (CASP3), energy production (ATPs), and general stress response (hsp70).

The RAS-MAPK pathway regulates cell proliferation, differentiation and survival, and its dysregulation is associated with cancer development. The pathway minimally comprises the small GTPase RAS and the kinases RAF, MEK and ERK. Activation of RAF by RAS is notoriously intricate and remains only partially understood.
