From Crop Residue to Corrugated Core Sandwich Panels as a Building Material.

This study explores the potential of using underutilized materials from agricultural and forestry systems, such as rice husk, wheat straw, and wood strands, in developing corrugated core sandwich panels as a structural building material. By leveraging the unique properties of these biobased materials within a corrugated geometry, the research presents a novel approach to enhancing the structural performance of such underutilized biobased materials. These biobased materials were used in different lengths to consider the manufacturing feasibility of corrugated panels and the effect of fiber length on their structural performance.

Older people's perspectives on frailty screening in primary care settings - a citizens' jury study.

Background: As the world's population ages, there is a growing concern with frailty, marked by reduced strength and greater vulnerability to stress. Overcoming obstacles like reluctance towards screening methods in this process is crucial for identifying and addressing frailty at an early stage. Understanding older people's perspectives can help adapt screening procedures in primary healthcare settings.

Accelerated phase-contrast magnetic resonance imaging with use of resolution enhancement generative adversarial neural network.

Background: Cardiovascular magnetic resonance (CMR) phase contrast is used to quantify blood flow. We sought to develop a complex-difference reconstruction for inline super-resolution of phase-contrast flow (CRISPFlow) to accelerate phase-contrast imaging.

Methods: CRISPFlow was built on the super-resolution generative adversarial network.

Late gadolinium enhancement cardiovascular magnetic resonance with generative artificial intelligence.

Background: Late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) imaging enables imaging of scar/fibrosis and is a cornerstone of most CMR imaging protocols. CMR imaging can benefit from image acceleration; however, image acceleration in LGE remains challenging due to its limited signal-to-noise ratio. In this study, we sought to evaluate a rapid two-dimensional (2D) LGE imaging protocol using a generative artificial intelligence (AI) algorithm with inline reconstruction.

Influence of incorporating beta-cyclodextrin/essential oil-based wood preservative on the bonding strength of wood composite products.

The introduction of additives during the production of wood composites may disrupt the development of bonding strength between wood and adhesive, potentially compromising the structural performance of wood composites. This study investigates the impact of incorporating a natural wood preservative into 3-ply southern yellow pine (SYP) plywood on its bonding strength. The formation of β-cyclodextrin and trans-cinnamaldehyde (βCD-tCN) inclusion complex as a natural wood preservative was confirmed by Fourier transform infrared and X-ray diffraction analyses, with an inclusion yield ranging 78 % to 120 %.

Organoids as a model of status epilepticus.

Status epilepticus (SE) is a neurological emergency that can be studied in animal models, particularly mice. However, these models are labour-intensive and require large numbers of animals, which raises ethical and logistical challenges. Additionally, rodent-based models could lack direct relevance to human physiology.

Accelerated cardiac cine with spatio-coil regularized deep learning reconstruction.

Purpose: To develop an iterative deep learning (DL) reconstruction with spatio-coil regularization and multichannel k-space data consistency for accelerated cine imaging.

Methods: This study proposes a Spatio-Coil Regularized DL (SCR-DL) approach for iterative deep learning reconstruction incorporating multicoil information in data consistency and regularizer. SCR-DL uses shift-invariant convolutional kernels to interpolate missing k-space lines and reconstruct individual coil images, followed by a regularizer that operates simultaneously across spatial and coil dimensions using learned image priors.

Quantification of blood and CSF volume to predict outcome after aneurysmal subarachnoid hemorrhage.

This study aimed to describe the relationship between blood and CSF volumes in different compartments on baseline CT after aSAH, assess if they independently predict long-term outcome, and explore their interaction with age. CT scans from patients participating in a prospective multicenter randomized controlled trial of patients with aSAH were segmented for blood and CSF volumes. The primary outcomes were the mRS, and the Subarachnoid Hemorrhage Outcome Tool (SAHOT) at day 28 and 180.

The Influence of Wait Time on Surgical Outcomes in Elective Lumbar Degenerative Spine Conditions: A Retrospective Multicentre Cohort Study.

Study Design: Retrospective cohort study.

Objectives: The impact of delayed access to operative treatment on patient reported outcomes (PROs) for lumbar degenerative conditions remains unclear. The goal of this study is to evaluate the association between wait times for elective lumbar spine surgery and post-operative PROs.

The dorsal thalamic lateral geniculate nucleus is required for visual control of head direction cell firing direction in rats.

Head direction (HD) neurons, signalling facing direction, generate a signal that is primarily anchored to the outside world by visual inputs. We investigated the route for visual landmark information into the HD system in rats. There are two candidates: an evolutionarily older, larger subcortical retino-tectal pathway and a more recently evolved, smaller cortical retino-geniculo-striate pathway.

Activity levels across the intensity spectrum in athletes: a systematic review protocol.

Physical activity (PA) promotes better cardiometabolic health, physical function, brain health and longevity. In contrast, prolonged sedentary behaviour (SB) is a risk factor for many chronic diseases and poor health. Limited research has evaluated or synthesised how competitive sports participation influences PA across the lifespan.

Wood dimensional stability enhancement by multivalent metal-cation-induced lignocellulosic microfibrils crosslinking.

Wood is a hygroscopic material that responds to the moisture changes of the surrounding environment through swelling and shrinkage, making it dimensionally unstable. Here, we introduce a facile metal-ion-modification (MIM) approach to enhance the dimensional stability of wood. The MIM process involved swelling the wood samples with aqueous metal ion solutions and drying.
