Radiometric determination of rubisco activation state and quantity in leaves.

Rubisco is the key enzyme in photosynthesis, catalyzing fixation of carbon dioxide from the atmosphere into energy storage molecules. Several inefficiencies in Rubisco limit the rate of photosynthesis, and, therefore, the growth of the plant. Rubisco is sensitive to light, making deactivation of the enzyme upon sampling likely.

A multi-dimensional approach to the future of digital research infrastructure for systemic environmental science.

Digital research infrastructure (DRI) for environmental science requires significant transformation to support the changing nature of science and utilize digital innovations. Numerous challenges prevent this change yet simultaneously pose exciting principles to drive the future of DRI. This opinion piece details a multi-dimensional approach toward these futures for the environmental community.

Microbial and mineral interactions decouple litter quality from soil organic matter formation.

Current understanding of soil carbon dynamics suggests that plant litter quality and soil mineralogy control the formation of mineral-associated soil organic carbon (SOC). Due to more efficient microbial anabolism, high-quality litter may produce more microbial residues for stabilisation on mineral surfaces. To test these fundamental concepts, we manipulate soil mineralogy using pristine minerals, characterise microbial communities and use stable isotopes to measure decomposition of low- and high-quality litter and mineral stabilisation of litter-C.

Platinum Hour: Emergency Department Length of Stay and Trauma Patients' Outcomes.

Introduction: Trauma bay and emergency department (ED) length of stay (LOS) are important time measures in patient care. The data on this subject are inconclusive or specific to one condition. Our goal was to determine the relationship between ED LOS and outcomes or mortality of trauma patients.

Developmentally regulated generation of a systemic signal for long-lasting defence priming in tomato.

Tomato is a major global crop. However, its production is limited by Botrytis cinerea. Due to the toxicity of postharvest pesticide application, alternative control methods such as priming are being investigated.

The nature of label-induced categories: preverbal infants represent surface features and category symbols.

Humans categorize objects not only based on perceptual features (e.g. red, rounded), but also function (e.

A worldwide study of subcortical shape as a marker for clinical staging in Parkinson's disease.

Alterations in subcortical brain regions are linked to motor and non-motor symptoms in Parkinson's disease (PD). However, associations between clinical expression and regional morphological abnormalities of the basal ganglia, thalamus, amygdala and hippocampus are not well established. We analyzed 3D T1-weighted brain MRI and clinical data from 2525 individuals with PD and 1326 controls from 22 global sources in the ENIGMA-PD consortium.

Can the left hand benefit from being right? The influence of body side on perceived grasping ability.

Right-handed individuals (RHIs) demonstrate perceptual biases towards their right hand, estimating it to be larger and longer than their left. In addition, RHIs estimate that they can grasp larger objects with their right hand than their left. This study investigated whether visual information specifying handedness enhances biases in RHIs' perceptions of their action capabilities.

Between epistemic injustice and therapeutic jurisprudence: Coronial processes involving families of autistic people, people with learning disabilities and/or mental ill health.

Understanding how and why someone dies unexpectedly is key to bereaved family members. The coronial process in England investigates instances where the cause of death is unknown, violent or unnatural and/or occurred in state detention. Families are held to be at the centre of this process and the coroner's role has extended to concern about therapeutic jurisprudence, that is, how legal processes can minimise negative consequences for participants without jeopardising due process.

Syndemic geographic patterns of cancer risk in a health-deprived area of England.

Objectives: This study aims to analyse the geographical co-occurrence of cancers and their individual and shared risk factors in a highly deprived area of the North West of England to aid the identification of potential interventions.

Study Design: An ecological study design was employed and applied at postcode sector level in the Morecambe Bay region.

Methods: A novel spatial joint modelling framework designed to account for large frequencies of left-censored cancer data was employed.

Thinking politically about intersectoral action: Ideas, Interests and Institutions shaping political dimensions of governing during COVID-19.

Our paper examines the political considerations in the intersectoral action that was evident during the SAR-COV-2 virus (COVID-19) pandemic through case studies of political and institutional responses in 16 nations (Australia, Belgium, Brazil, Ethiopia, India, New Zealand, Nigeria, Peru, South Africa, South Korea, Spain, Taiwan, Thailand, Vietnam, UK, and USA). Our qualitative case study approach involved an iterative process of data gathering and interpretation through the three Is (institutions, ideas and interests) lens, which we used to shape our understanding of political and intersectoral factors affecting pandemic responses. The institutional factors examined were: national economic and political context; influence of the global economic order; structural inequities; and public health structures and legislation, including intersectoral action.

Real-world experience of paediatric acute promyelocytic leukaemia in the United Kingdom and Ireland.

Acute promyelocytic leukaemia (APL), defined by the t(15;17)(q24;q21) translocation, accounts for 5%-10% of paediatric acute myeloid leukaemia cases. All-trans retinoic acid (ATRA) and arsenic trioxide (ATO) are key treatments, though ATO access varies. We evaluated treatment, complications and survival in 50 UK paediatric APL patients diagnosed between 2014 and 2021.

Efficacy and Safety of Combination AKT and Androgen Receptor Signaling Inhibition in Metastatic Castration-Resistant Prostate Cancer: Systematic Review and Meta-Analysis.

Background: Metastatic castration-resistant prostate cancer (mCRPC) has a poor prognosis with current treatment options including chemotherapy and androgen receptor signaling inhibitor (ARSI) medications. Poly-ADP ribose polymerase (PARP) inhibitors alone and in combination with ARSI has recently been incorporated in management for mCRPC deficient in BRCA1/2 genes. However, downregulating androgen-receptor signaling using ARSIs can upregulate the PI3K/AKT/mTOR pathway, promoting tumor cell survival.

Why are organisational approvals needed for low-risk staff studies in the UK? Procedures, barriers, and burdens.

Background: Health care staff should be given the opportunity to participate in research, but recruiting clinicians via their employing organisation is not always straightforward or quick in the UK. Unlike many countries outside the UK, very low-risk survey, interview or focus group studies can be subject to some of the same governance approval procedures as interventional studies. An exemplar study carried out by the NIHR funded Palliative Care Research Partnership North West Coast is used to highlight the challenges still faced by researchers and health care organisations when setting up a low-risk staff study across multiple NHS and non-NHS sites.

Efficacy of attractive targeted sugar bait stations against malaria in Western Province Zambia: epidemiological findings from a two-arm cluster randomized phase III trial.

Background: Attractive targeted sugar bait (ATSB) stations containing bait (to attract) and ingestion toxicant (to kill) sugar-foraging mosquitoes are hypothesized to reduce malaria transmission by shortening the lifespan of Anopheles vectors.

Methods: A two-arm cluster-randomized controlled trial (cRCT) was conducted in Western Province Zambia. Seventy clusters of 250-350 households were assigned (1:1) by restricted randomization to an intervention arm (ATSB) or control arm (no ATSB) in the context of standard of care vector control (insecticide-treated nets and/or indoor residual spraying).

Economic assessment of animal disease burden in Senegalese small ruminants.

Small ruminant production in sub-Saharan Africa is limited by a range of constraints, including animal health issues. This study aimed at estimating the impact of these issues on the small ruminant production in Senegal in a holistic manner, using an approach developed by the Global Burden of Animal Diseases (GBADs) programme. The estimation focused on the mixed crop-livestock system, representing a large proportion (>60 %) of the small ruminant population in the country.

Structure confirmation, reactivity, bacterial mutagenicity and quantification of 2,2,4-tribromo-5-hydroxycyclopent-4-ene-1,3-dione in drinking water.

The presence of two new disinfectant by-product (DBP) groups in the UK was recently shown using non-target analysis, halogenated-hydroxycyclopentenediones and halogenated-methanesulfonic acids. In this work, we confirmed the structure of 2,2,4-tribromo-5-hydroxycyclopent-4-ene-1,3-dione (TBHCD), and quantified it together with dibromomethanesulfonic acid at 122 ± 34 and 326 ± 157 ng L on average in London's drinking water, respectively (n = 21). We found TBHCD to be photolabile and unstable in tap water and at alkaline pH.

Extreme electron-hole drag and negative mobility in the Dirac plasma of graphene.

Coulomb drag between adjacent electron and hole gases has attracted considerable attention, being studied in various two-dimensional systems, including semiconductor and graphene heterostructures. Here we report measurements of electron-hole drag in the Planckian plasma that develops in monolayer graphene in the vicinity of its Dirac point above liquid-nitrogen temperatures. The frequent electron-hole scattering forces minority carriers to move against the applied electric field due to the drag induced by majority carriers.
