WHO guidelines on waist circumference and physical activity and their joint association with cancer risk.

Objective: Low body fat and high physical activity levels are key lifestyle factors in cancer prevention, but the interplay of abdominal obesity and physical activity on cancer risk remains unknown. We explored individual and joint associations of waist circumference and physical activity with cancer risk.

Methods: Using UK Biobank data (n=315 457), we categorised individuals according to WHO guideline thresholds for waist circumference and self-reported physical activity levels.

Toll/interleukin-1 receptor-only genes contribute to immune responses in maize.

Proteins with Toll/interleukin-1 receptor (TIR) domains are widely distributed in both prokaryotes and eukaryotes, serving as essential components of immune signaling. Although monocots lack the major TIR-nucleotide-binding (NB)-leucine-rich repeat (LRR)-type (TNL) immune receptors, they possess a small number of TIR-only proteins, the function of which remains largely unknown. In the monocot maize (Zea mays), there are three conserved TIR-only genes in the reference genome, namely ZmTIR1 to ZmTIR3.

Airway clearance techniques for people with acute exacerbation of COPD: a scoping review.

Introduction: Acute exacerbations of COPD (AECOPD) often involve mucus hypersecretion. Thus, management of sputum retention is critical. However, the use of airway clearance techniques (ACTs) in people with AECOPD across different healthcare settings and factors influencing their selection remain unclear.

Lightweight 3D-printed chitosan/MXene aerogels for advanced electromagnetic shielding, energy harvesting, and thermal management.

This study focuses on the fabrication of 3D-printed chitosan/TiCT-MXene aerogels with varying MXene concentrations (1, 2, 5, and 10 wt%) using the direct ink writing (DIW) method. The inks were freeze-dried to form aerogels, and FTIR and XRD analyses confirmed interactions between chitosan and MXene molecules, leading to increased spacing between MXene nanosheets. Rheological testing showed improved shear-thinning behavior, enhancing printability.

Enhanced analysis of cellulose nanofibril film structure.

Structural analysis of cellulose nanofibril (CNF) films remains challenging due to the stochastic assembly of fibres and presence of nanopores. This limits our ability to link the film structures to their properties, restricting their commercial use. While X-ray micro-computed tomography (μCT) is a powerful technique to map the structure of traditional and commercial paper, there has been limited success in its application for CNF films due to the poor contrast between pores and material, making the reconstructed images difficult to segment and analyse.

Effect of crosslinker length in CNF foams for oil recovery and sustainable agriculture.

Chemically crosslinked foams possess good wet mechanical stability, and they are promising systems for applications in oil recovery, water treatment, energy storage, etc. However, reports on the effect of crosslinker length on the physical properties of the foam are scarce. Various cellulose nanofiber (CNF) foams (denoted as CPM) were prepared using different molecular weights dicarboxylated-PEG crosslinkers via the esterification reaction.

Bioinspired complex cellulose nanorod-architectures: A model for dual-responsive smart carriers.

The synergy between nanomaterials as solid supports and supramolecular concepts has resulted in nanomaterials with hierarchical structure and enhanced functionality. Herein, we developed and investigated innovative supramolecular functionalities arising from the synergy between organic moieties and the preexisting nanoscale soft material backbones. Based on these complex molecular nano-architectures, a new nanorod carbohydrate polymer carrier was designed with bifunctional hairy nanocellulose (BHNC) to reveal dual-responsive advanced drug delivery (ADD).

The inverse electron demand diels-alder (IEDDA): A facile bioorthogonal click reaction for development of injectable polysaccharide-based hydrogels for biomedical applications.

The inverse electron demand Diels-Alder (IEDDA) cycloaddition between tetrazines and strained dienophiles is recognized as a fast and specific reaction. The integrating tetrazines and strained dienophiles onto the backbone of polysaccharides yield appropriate water-soluble precursors for IEDDA cycloaddition. Due to the high specificity of the IEDDA reaction and its outstanding cytocompatibility, a range of cargos (live cells, peptides and pharmaceuticals) can be effectively encapsulated in polysaccharide solutions throughout the hydrogel formation.

Synthesis and characterization of photo-cross-linkable quince seed-based hydrogels for soft tissue engineering applications.

The convenience, versatility, and biocompatibility of photocrosslinkable hydrogel precursors make them promising candidates for developing tissue engineering scaffolds. However, the current library of photosensitive materials is limited. This study reports, for the first time, the modification of quince seed mucilage (QS) with glycidyl methacrylate (GM), resulting in the synthesis of methacrylated QS (QSGM).

Influence of sex on sympathetic vasomotor outflow responses to passive leg raising in young individuals.

The purpose of this study was to clarify sex differences in the inhibition of sympathetic vasomotor outflow which is caused by the loading of cardiopulmonary baroreceptors. Ten young males and ten age-matched females participated. The participants underwent a passive leg raising (PLR) test wherein they were positioned supine (baseline, 0º), and their lower limbs were lifted passively at 10º, 20º, 30º, and 40º.

Development and validation of machine-learning models for predicting the risk of hypertriglyceridemia in critically ill patients receiving propofol sedation using retrospective data: a protocol.

Introduction: Propofol is a widely used sedative-hypnotic agent for critically ill patients requiring invasive mechanical ventilation (IMV). Despite its clinical benefits, propofol is associated with increased risks of hypertriglyceridemia. Early identification of patients at risk for propofol-associated hypertriglyceridemia is crucial for optimising sedation strategies and preventing adverse outcomes.

What is the current state of precision rehabilitation? Protocol for a scoping study with a consultation phase.

Introduction: Precision health can be described as the right intervention, at the right time, for the right person, with a focus on monitoring and maintaining health in a longitudinal approach. Despite an increasing focus on precision approaches in medicine, their application in a rehabilitation context remains unexplored. As such, a greater understanding of the current state of the literature is required, in combination with clinician, researcher and healthcare manager perspectives regarding barriers and facilitators to the practical implementation of precision rehabilitation in clinical practice.

On the Role of Epigenetic Modifications of HPA Axis in Post Traumatic Stress Disorder (PTSD) and Resilience.

Stress is a fundamental adaptive response mediated by the amygdala and Hypothalamus-Pituitary-Adrenal (HPA) axis. Extreme or chronic stress, however, can result in a multitude of neuropsychiatric disorders, including anxiety, paranoia, bipolar disorder (BP), major depressive disorder (MDD), and Post-Traumatic Stress Disorder (PTSD). Despite widespread exposure to trauma (70.

Differences in Care and Outcomes in Cardiogenic Shock in Cardiac Intensive Care Units in the United States and Canada: CCCTN Registry Insights.

Background: Mortality in cardiogenic shock (CS) remains high. Significant inter-hospital heterogeneity in critical care therapies have been described, which reflects the lack of high-quality evidence to guide optimal treatment. We aimed to describe differences in practices and clinical outcomes among patients with CS in the United States (US) and Canada.

Comparative Analysis of Conversion and Crosslinking Degree in Bulk-Fill, Monochromatic, and ORMOCER composites.

Bulk-fill, monochromatic, and ORMOCER composites were introduced in restorative dentistry with the aim of reducing clinical time and/or alleviating contraction stresses at the interface between the tooth and restoration. While the conversion and immediate properties of these materials are comparable to conventional composites, studies evaluating their long-term properties and the structure of the polymer matrix are lacking. The objective of this study was to evaluate the degree of conversion and, indirectly, the crosslink density of conventional, bulk-fill, monochromatic, and ORMOCER resin composites.
