Network Architecture of Leaf Trait Correlations Has Shifted Following Crop Domestication.

Domestication of crops with the goal of improving yield has led to spectacular shifts in phenotypic traits and their correlation patterns. However, it is relatively unknown whether domestication has driven variation in the architecture of trait correlation networks to optimise carbon return on construction cost along the leaf economics spectrum (LES). Here, we compiled a data set of leaf functional, biochemical, and anatomical traits of 54 wild and cultivated crops.

Targeted oxygenation in the respiratory care of premature infants at delivery-effects on outcome: a randomised controlled trial (Torpido 3060) study protocol.

Introduction: The safest oxygen levels needed for preterm infant respiratory support at birth are uncertain. We aimed to compare the outcomes of infants up to 28 weeks gestation who had respiratory care initiated at birth with fractional inspired oxygen (FiO) 0.3 or 0.

Soil Nitrogen Supply Exerts Largest Influence on Leaf Nitrogen in Environments with the Greatest Leaf Nitrogen Demand.

Accurately representing the relationships between nitrogen supply and photosynthesis is crucial for reliably predicting carbon-nitrogen cycle coupling in Earth System Models (ESMs). Most ESMs assume positive correlations amongst soil nitrogen supply, leaf nitrogen content, and photosynthetic capacity. However, leaf photosynthetic nitrogen demand may influence the leaf nitrogen response to soil nitrogen supply; thus, responses to nitrogen supply are expected to be the largest in environments where demand is the greatest.

Relationship between wind speed and plant hydraulics at the global scale.

Wind is an important ecological factor for plants as it can increase evapotranspiration and cause dehydration. However, the impact of wind on plant hydraulics at a global scale remains unclear. Here we compiled plant key hydraulic traits, including water potential at 50% loss of hydraulic conductivity (P), xylem-specific hydraulic conductivity (K), leaf area to sapwood area ratio (A/A) and conduit diameter (D) with 2,786 species-at-site combinations across 1,922 woody species at 469 sites worldwide and analysed their correlations with wind speed.

The ratio of reactive oxygen and nitrogen species determines the type of cell death that bacteria undergo.

Reactive oxygen and nitrogen species (RONS) are emerging as a novel antibacterial strategy to combat the alarming increase in antimicrobial resistance (AMR). RONS can inhibit bacterial growth through reactions with cellular molecules, compromising vital biological functions and leading to cell death. While their mechanisms of action have been studied, many remain unclear, especially in biologically relevant environments.

Temperature and plant-available soil phosphorus drive intraspecific variation in plant economic traits of Schima superba across an elevation gradient.

Background And Aims: The whole-plant economics spectrum (PES) describes coordination between organ-level traits that together determine resource use strategies and is relevant for understanding plant responses to environmental change. Whereas coordination between organs has previously been explored across species, it remains unclear whether patterns observed across species hold within species. In addition, the key driving forces underlying this coordination warrant clarification.

A Pilot Randomized Control Trial of the Motivational Interviewing to Increase PrEP Uptake Intervention Among Black Women in the United States.

Despite the disproportional impact of HIV, Black individuals are benefiting the least from pre-exposure prophylaxis (PrEP). Motivational interviewing (MI) for PrEP uptake (MI-PrEP) is a two-session culturally tailored intervention incorporating MI strategies to improve PrEP motivation and uptake among cisgender Black women. A pilot randomized control trial was conducted in the Southeastern United States, and 41 women were randomized to MI-PrEP (session 1 with PrEP psychoeducation and MI and session 2 with MI and light case management) or enhanced treatment as usual (ETAU; two sessions of PrEP psychoeducation [videos explaining PrEP]).

First report of accumulation of perfluorooctane sulfonate (PFOS) in platypuses (Ornithorhynchus anatinus) in New South Wales, Australia.

The platypus (Ornithorhynchus anatinus) is a semi-aquatic monotreme that occupies a high trophic position in the freshwater ecosystems of eastern mainland Australia and Tasmania. Platypuses are continuously exposed to anthropogenic contaminants including perfluorooctane sulfonate (PFOS). This study examined PFOS concentrations in the livers of deceased platypuses (eight wild; one captive) that were opportunistically collected across NSW over a two- and a half-year period.

Cardiac implantable electronic devices in pregnancy: A position statement.

The aim of this document is to provide guidance for the management of women and birthing people with a permanent pacemaker (PPM) or implantable cardioverter defibrillator (ICD). Cardiac devices are becoming more common in obstetric practice and a reference document for contemporary evidence-based practice is required. Where evidence is limited, expert consensus has established recommendations.

Theory and tests for coordination among hydraulic and photosynthetic traits in co-occurring woody species.

Co-occurring plants show wide variation in their hydraulic and photosynthetic traits. Here, we extended 'least-cost' optimality theory to derive predictions for how variation in key hydraulic traits potentially affects the cost of acquiring and using water in photosynthesis and how this, in turn, should drive variation in photosynthetic traits. We tested these ideas across 18 woody species at a temperate woodland in eastern Australia, focusing on hydraulic traits representing different aspects of plant water balance, that is storage (sapwood capacitance, C), demand vs supply (branch leaf : sapwood area ratio, A : A and leaf : sapwood mass ratio and M : M), access to soil water (proxied by predawn leaf water potential, Ψ) and physical strength (sapwood density, WD).

A Pilot Randomized Control Trial of the Striving Towards EmPowerment and Medication Adherence (STEP-AD) Intervention for Black Women Living with HIV.

Black women living with HIV (BWLWH) face adversities associated with lower HIV medication adherence, viral non-suppression, and mental health symptoms (e.g., post-traumatic stress disorder) such as trauma/violence, racism, HIV-related discrimination/stigma, and gender-related stressors.

Control of companion animal parasites and impact on One Health.

The last decades have witnessed an increase in the global population and movements of companion animals, contributing to changes in density and distribution of pet parasites. Control of companion animal parasites (CAPs) becomes increasingly relevant because of the intensifying human-animal bond. Parasites impact on the health of humans and their pets, but also of wildlife and the environment.

The AusTraits plant dictionary.

Traits with intuitive names, a clear scope and explicit description are essential for all trait databases. The lack of unified, comprehensive, and machine-readable plant trait definitions limits the utility of trait databases, including reanalysis of data from a single database, or analyses that integrate data across multiple databases. Both can only occur if researchers are confident the trait concepts are consistent within and across sources.

Blood volume reduction due to rapid plasma loss after birth in preterm piglets.

Background: Understanding changes in blood volume after preterm birth is critical to preventing cardiovascular deterioration in preterm infants. The aims were to determine if blood volume is higher in preterm than term piglets and if blood volume changes in the hours after birth.

Methods: Paired blood volume measurements were conducted in preterm piglets (98/115d gestation, ~28wk gestation infant) at 0.

Therapeutic potential of conduction system pacing as a method for improving cardiac output during ventricular tachycardia.

Background: Ventricular tachycardia (VT) reduces cardiac output through high heart rates, loss of atrioventricular synchrony, and loss of ventricular synchrony. We studied the contribution of each mechanism and explored the potential therapeutic utility of His bundle pacing to improve cardiac output during VT.

Methods: Study 1 aimed to improve the understanding of mechanisms of harm during VT (using pacing simulated VT).

Linking nematodes and ecosystem function: a trait-based framework.

Trait-based approaches are being increasingly adopted to understand species' ecological strategies and how organisms influence ecosystem function. Trait-based research on soil organisms, however, remains poorly developed compared with that for plants. The abundant and diverse soil nematodes are prime candidates to advance trait-based approaches belowground, but a unified trait framework to describe nematode ecological strategies and assess their linkages with ecosystem function is lacking.

Machine learning-derived cycle length variability metrics predict spontaneously terminating ventricular tachycardia in implantable cardioverter defibrillator recipients.

Aims: Implantable cardioverter defibrillator (ICD) therapies have been associated with increased mortality and should be minimized when safe to do so. We hypothesized that machine learning-derived ventricular tachycardia (VT) cycle length (CL) variability metrics could be used to discriminate between sustained and spontaneously terminating VT.

Methods And Results: In this single-centre retrospective study, we analysed data from 69 VT episodes stored on ICDs from 27 patients (36 spontaneously terminating VT, 33 sustained VT).

Fractures in Thoroughbred racing and the potential for pre-race identification of horses at risk.

Risk rates for and predisposing factors to fractures occurring in Thoroughbred racing that have been published in peer reviewed journals are documented. The potential for currently available techniques to identify horses at increased risk for fracture is discussed on the bases of principles, practicalities, advantages, disadvantages and current data. All are reviewed in light of justifiable decision making and importance of fractures to horseracing's social license.

Leaf phosphorus fractions vary with leaf economic traits among 35 Australian woody species.

Adaptations of plants to phosphorus (P) deficiency include reduced investment of leaf P in storage (orthophosphates in vacuoles), nucleic acids and membrane lipids. Yet, it is unclear how these adaptations are associated with plant ecological strategies. Five leaf P fractions (orthophosphate P, P ; metabolite P, P ; nucleic acid P, P ; lipid P, P ; and residual P, P ) were analysed alongside leaf economic traits among 35 Australian woody species from three habitats: one a high-P basalt-derived soil and two low-P sandstone-derived soils, one undisturbed and one disturbed by human activities with artificial P inputs.
