Marine plastic pollution has emerged as one of the most pressing environmental challenges of our time. Although there has been a surge in global investment for implementing interventions to mitigate plastic pollution, there has been little attention given to the cost of these interventions. We developed a decision support framework to identify the economic, social, and ecological costs and benefits of plastic pollution interventions for different sectors and stakeholders.

Here, we use 60 million bird observations from eBird to estimate the sensitivity to human pressure of each bird species breeding in the Americas. Concerningly, we find that ecoregions hosting large proportions of high-sensitivity species, concentrated in tropical biomes, do not have more intact protected habitat.

The aim of this study was to determine body composition among patients with retroperitoneal and trunk sarcoma, and assess impact on operative and oncologic outcomes.
Methods: Consecutive patients undergoing treatment with curative intent from 2009 to 2019 were studied.
Evolution is a prominent component of biology education and remains controversial among college biology students in the United States who are mostly Christian, but science education researchers have not explored the attitudes of Muslim biology students in the United States. To explore perceptions of evolution among Muslim students in the United States, we surveyed 7,909 college students in 52 biology classes in 13 states about their acceptance of evolution, interest in evolution, and understanding of evolution. Muslim students in our sample, on average, did not agree with items that measured acceptance of macroevolution and human evolution.

Purpose: In the past 3 decades, synchrotron microbeam radiation therapy (S-MRT) has been shown to achieve both good tumor control and normal tissue sparing in a range of preclinical animal models. However, the use of S-MRT for the treatment of lung tumors has not yet been investigated. This study is the first to evaluate the therapeutic efficacy of S-MRT for the treatment of lung carcinoma, using a new syngeneic and orthotopic mouse model.

In the context of the Convention on Biological Diversity's negotiations on the post-2020 Global Biodiversity Framework, we find that targets for area-based interventions are framed overwhelmingly with measures that fail to inform decision-makers about impact and that risk diverting limited resources away from achieving it. We show that predicting impact in space and time is feasible and can provide the basis for global guidance for jurisdictions to develop targets for conservation impact and shift investment priorities to areas where impact can be most effectively achieved.
View Article and Find Full Text PDFA novel method of producing fluorine-18 for Positron emission tomography (PET) scan applications is evaluated theoretically. The method is based upon the He(d,p)He nuclear reaction from which the protons produced are used to produce fluorine-18 via the O(p,n)F reaction. The potential advantage of such a system over cyclotron-based production is of lower input beam energy, which may lower the cost of the system and potentially allow for onsite production.

However, quantitative research has not explored the unique impact of student perceived conflict between their religion and evolution as a major factor influencing evolution acceptance. We developed an instrument with validity evidence called "Perceived Conflict between Evolution and Religion" (PCoRE).

This study assessed whether extending the major rest break between shifts from 7-hours (Australian industry standard) to 11-hours, improved drivers' sleep, alertness and naturalistic driving performance.

Background/aims: Despite epistaxis being a common presentation to emergency departments there is a lack of guidelines, both nationally and internationally, for its management. The authors reviewed the current management of epistaxis and then introduced a new pathway for management to see if care could be improved. The aims were to evaluate the impact of the pathway on reduction of emergency department breaches, emergency ambulance transfers and hospital admissions.

UK-produced LICBT guided self-help (GSH) materials were originally used in the MindStep™ program. In 2017, Australian LICBT GSH materials were developed to better suit Australian users.

Mice were exposed to filtered air, heat-inactivated r (3 × 10 spores), or viable r (3 × 10 spores) via nose-only inhalation exposure 2 times per week for 1, 2, or 4 weeks. Analysis of cortex, midbrain, olfactory bulb, and cerebellum tissue from mice exposed to viable r spores for 1, 2, and 4 weeks revealed significantly elevated pro-inflammatory () and glial activity ( and ) gene expression in several brain regions when compared to filtered air control, with the most consistent and pronounced neuroimmune response 48H following the 4-week exposure in the midbrain and frontal lobe.

Clarifying the terminology and recommendations for its future use in biomonitoring," Pawlowski et al. argue that the term eDNA should be used to refer to the pool of DNA isolated from environmental samples, as opposed to only extra-organismal DNA from macro-organisms. We agree with this view.

This study summarises and critically evaluates the current evidence-based literature on body mass index (BMI) and body composition among patients with STS, with respect to clinical and pathologic characteristics, treatment-associated morbidity and oncologic outcome.
Methods: A systematic literature search of the PubMed, Embase and Cochrane databases was performed.
Pharmacological management of chronic neuropathic pain (CNP) still represents a major clinical challenge. Collective harnessing of both the scientific evidence base and clinical experience (of clinicians and patients) can play a key role in informing treatment pathways and contribute to the debate on specific treatments (e.g.

However, ligand RNA assays have not been adopted into routine practice due to issues with analytic precision and practicality. We investigated whether AREG/EREG IHC could predict benefit from the anti-EGFR agent panitumumab.
