Food odour perception and affective response in Virtual spacecraft and microgravity body posture (1-G) - Potential ground-based simulations.

This study investigates food odour perception and affective response within a virtually simulated spacecraft environment, with links to the volatile composition of odours. Healthy participants (n = 44) between the ages of 18-39 years rated the intensity of eight food odours in two simulated space environments for comparison, a 'microgravity' posture (MicroG Posture; physical) and Virtual Reality (VR; visual-spatial cues) simulation of a spacecraft. Results indicate that these methods yield different outcomes.

Gluteus Medius for Individuals with Chronic Ankle Instability: Assessing Muscle Activity.

Emerging evidence has suggested that gluteus medius (GM) muscle activity may be critical for functional performance in individuals with chronic ankle instability (CAI). This study aimed to systematically review the literature to determine whether there are differences in GM muscle activity between individuals with and without CAI. A comprehensive search in PubMed, Embase, Cochrane Library, Web of Science, EBSCO, and PEDro databases was undertaken from the year of inception to 10 June 2024.

The 1978 English boarding school influenza outbreak: where the classic SEIR model fails.

Previous work has failed to fit classic SEIR epidemic models satisfactorily to the prevalence data of the famous English boarding school 1978 influenza A/H1N1 outbreak during the children's pandemic. It is still an open question whether a biologically plausible model can fit the prevalence time series and the attack rate correctly. To construct the final model, we first used an intentionally very flexible and overfitted discrete-time epidemiologic model to learn the epidemiological features from the data.

Differences in landing biomechanics in the presence of delayed onset muscle soreness following or not active recovery.

Objective: Delayed onset muscle soreness (DOMS) can reduce joint range of motion and strength, cause edema, and increase joint stiffness. Here we set out to determine whether quadriceps DOMS followed by an active recovery low-intensity exercise alters jump landing biomechanics.

Methods: 3D landing kinematics, kinetics, and DOMS were evaluated in 26 healthy adults (15 women) performing drop and vertical jump landings before and after a squat protocol to induce quadriceps DOMS.

Neonatal overfeeding attenuates microgliosis and hippocampal damage in an infant rat model of pneumococcal meningitis.

Background: Pneumococcal meningitis (PM) triggers apoptotic neuronal and progenitor cell death in the hippocampal dentate gyrus (DG), resulting in subsequent cognitive impairment. Microglia play a crucial role in PM-induced hippocampal damage. While the lasting effects of neonatal nutrition on health are well documented, the influence of early-life overfeeding on the host response to neuroinfections remains uncertain.

Early-Life Respiratory Syncytial Virus (RSV) Infection Triggers Immunological Changes in Gut-Associated Lymphoid Tissues in a Sex-Dependent Manner in Adulthood.

Severe respiratory syncytial virus (RSV) infection during early life has been linked to gut dysbiosis, which correlates with increased disease severity and a higher risk of developing asthma later in life. However, the impact of such early-life RSV infections on intestinal immunity in adulthood remains unclear. Herein, we show that RSV infection in 3-week-old mice induced persistent differential natural killer (NK) and T cell profiles within the lungs and gastrointestinal (GI) lymphoid tissues (GALT) in adulthood.

Surface Optimization of Noble-Metal-Free Conductive [MnCoNi]O Nanosheets for Boosting Their Efficacy as Hybridization Matrices.

Conductive 2D nanosheets have evoked tremendous scientific efforts because of their high efficiency as hybridization matrices for improving diverse functionalities of nanostructured materials. To address the problems posed by previously reported conductive nanosheets like poorly-interacting graphene and cost-ineffective RuO nanosheets, economically feasible noble-metal-free conductive [MnCoNi]O oxide nanosheets are synthesized with outstanding interfacial interaction capability. The surface-optimized [MnCoNi]O nanosheets outperformed RuO/graphene nanosheets as hybridization matrices in exploring high-performance visible-light-active (λ >420 nm) photocatalysts.

Sustainable lithium extraction enabled by responsive metal-organic frameworks with ion-sieving adsorption effects.

Metal-organic frameworks (MOFs) are superior ion adsorbents for selectively capturing toxic ions from water. Nevertheless, they have rarely been reported to have lithium selectivity over divalent cations due to the well-known flexibility of MOF framework and the similar physiochemical properties of Li and Mg. Herein, we report an ion-sieving adsorption approach to design sunlight-regenerable lithium adsorbents by subnanoporous MOFs for efficient lithium extraction.

Nanohybrids of BCN-FeS for Sodium and Lithium Hybrid Ion Capacitors.

Hybrid ion capacitors (HIC) are receiving a lot of attention due to their potential to achieve high energy and power densities, but they remain insufficient. It is imperative to explore outstanding and environmentally benign electrode materials to achieve high-performing HIC systems. Here, a unique boron carbon nitride (BCN)-based HIC system that comprises a microporous BCN structure and FeS nanoparticle incorporated BCN nanosheets (BNF) as cathode and anode, respectively is reported.

The increased demand for cladding in high-rise buildings has prompted engineers to explore alternative products utilizing recycled materials. However, ensuring fire compliance in these alternative claddings, which are predominantly composed of low-volume polymer-based composites, poses a critical challenge. Traditional experimental methods for fire evaluation are costly, time consuming, and environmentally impactful.

Utilising the Nanozymatic Activity of Copper-Functionalised Mesoporous C N for Sensing Biomolecules.

Designing unique nanomaterials for the selective sensing of biomolecules is of significant interest in the field of nanobiotechnology.

Comparative Longitudinal Serological Study of Anti-SARS-CoV-2 Antibody Profiles in People with COVID-19.

Serological diagnostic assays are essential tools for determining an individual's protection against viruses like SARS-CoV-2, tracking the spread of the virus in the community, and evaluating population immunity. To assess the diversity and quality of the anti-SARS-CoV-2 antibody response, we have compared the antibody profiles of people with mild, moderate, and severe COVID-19 using a dot blot assay. The test targeted the four major structural proteins of SARS-CoV-2, namely the nucleocapsid (N), spike (S) protein domains S1 and S2, and receptor-binding domain (RBD).
