Reliable crash analysis: Comparing biases and error rates of empirical Bayes before-after analyses to mixed-models.

Estimating reliable causal estimates of road safety interventions is challenging, with a number of these challenges addressable through analysis choices. At a minimum, developing reliable crash modification factors (CMFs) needs to address three critical confounding factors, i.e.

Prehatch Calls and Coordinated Birth in Turtles.

Hatching synchronisation is widespread in oviparous taxa. It has been demonstrated that many species use sounds to coordinate synchronous hatching, being widespread among archosaurs (birds and crocodilians). Recent studies have shown that some turtle species produce vocalisations from within the egg, but the role of this behaviour in synchronising hatch is untested.

Arbuscular mycorrhizal fungal interactions bridge the support of root-associated microbiota for slope multifunctionality in an erosion-prone ecosystem.

The role of diverse soil microbiota in restoring erosion-induced degraded lands is well recognized. Yet, the facilitative interactions among symbiotic arbuscular mycorrhizal (AM) fungi, rhizobia, and heterotrophic bacteria, which underpin multiple functions in eroded ecosystems, remain unclear. Here, we utilized quantitative microbiota profiling and ecological network analyses to explore the interplay between the diversity and biotic associations of root-associated microbiota and multifunctionality across an eroded slope of a plantation on the Loess Plateau.

The AUstralian multidomain Approach to Reduce dementia Risk by prOtecting brain health With lifestyle intervention study (AU-ARROW): A study protocol for a single-blind, multi-site, randomized controlled trial.

Introduction: The Finnish Geriatric Intervention Study (FINGER) led to the global dementia risk reduction initiative: World-Wide FINGERS (WW-FINGERS). As part of WW-FINGERS, the Australian AU-ARROW study mirrors aspects of FINGER, as well as US-POINTER.

Method: AU-ARROW is a randomized, single-blind, multisite, 2-year clinical trial ( = 600; aged 55-79).

Whole-mitogenome analysis unveils previously undescribed genetic diversity in cane toads across their invasion trajectory.

Invasive species offer insights into rapid adaptation to novel environments. The iconic cane toad () is an excellent model for studying rapid adaptation during invasion. Previous research using the mitochondrial NADH dehydrogenase 3 () gene in Hawai'ian and Australian invasive populations found a single haplotype, indicating an extreme genetic bottleneck following introduction.

Complete hydatidiform mole with concurrent fetus: Two cases of live, term birth coupled with spontaneous resolution of molar tissue.

Pregnancies with a complete hydatidiform mole and co-existing fetus (CMCF) are rare, but increasingly common due to the rising prevalence of assisted reproductive technology. They are frequently associated with adverse obstetric outcomes, providing women with the challenge of pregnancy termination or continuing the pregnancy at the risk of maternal-fetal morbidity and fetal mortality. This report demonstrates two cases of CMCF pregnancy with excellent maternal-fetal outcomes, including spontaneous resolution of the molar tissue antenatally.

Exome-based new allele-specific PCR markers and transferability for sodicity tolerance in bread wheat ( L.).

Targeted exome-based genotype by sequencing (t-GBS), a sequencing technology that tags SNPs and haplotypes in gene-rich regions was used in previous genome-wide association studies (GWAS) for sodicity tolerance in bread wheat. Thirty-nine novel SNPs including 18 haplotypes for yield and yield-components were identified. The present study aimed at developing SNP-derived markers by precisely locating new SNPs on ~180 bp allelic sequence of t-GBS, marker validation, and SNP functional characterization based on its exonic location.

Pruritus as an early sign of abnormal scarring in the re-epithelialising phase of Toxic Epidermal Necrolysis.

We present a 28-year-old remote-living male who presented to our dermatology clinic with increasing pruritus over his torso and limbs in the context of a recent admission for Toxic Epidermal Necrolysis (TEN) secondary to paliperidone depot. Our case demonstrates that pruritus in the re-epithelialising phase of TEN may be a sign of abnormal scarring. Early assessment and measurement for compression garments is recommended.

Humidity stress and its consequences for male pre- and post-copulatory fitness traits in an insect.

Global declines in insect abundance are of significant concern. While there is evidence that climate change is contributing to insect declines, we know little of the direct mechanisms responsible for these declines. Male fertility is compromised by increasing temperatures, and the thermal limit to fertility has been implicated as an important factor in the response of insects to climate change.

Curcumin: A dietary phytochemical for boosting exercise performance and recovery.

Curcumin, as the main natural compound in the turmeric plant (), is a yellowish polyphenol that has been used traditionally in Asian countries as a medicinal herb for various types of disease and pathological conditions caused by inflammation and oxidative stress. In the present review, we conducted a comprehensive literature search for evidence that shows the effect of curcumin on factors influencing exercise performance, including muscle damage, muscle soreness, inflammation, and oxidative stress. During exercise, reactive oxygen species and inflammation are increased.

Repeated Measures of Modified Rankin Scale Scores to Assess Functional Recovery From Stroke: AFFINITY Study Findings.

Background Function after acute stroke using the modified Rankin Scale (mRS) is usually assessed at a point in time. The analytical implications of serial mRS measurements to evaluate functional recovery over time is not completely understood. We compare repeated-measures and single-measure analyses of the mRS from a randomized clinical trial.

Decadal abundance patterns in an isolated urban reptile assemblage: Monitoring under a changing climate.

Determine seasonal, annual, and decadal patterns of abundance in reptile species and assemblages occupying central Bold Park (~338 ha), an isolated urban bushland remnant in Perth, Southwestern Australia. Fenced pitfall trapping in four sampling sites, representing different habitats and fire history, over the primary reptile activity period for 35 consecutive years with over 17,000 individuals captured during 3300 days of sampling; the trapping regime was modified for the last 28 years. Sampling occurred in one of 35 global biodiversity hotspots that has a Mediterranean climate experiencing a 15% decline from the century average rainfall over the last 50 years.

COVID-19 test-kit trade and trade policy: Implications for developing countries.

At the centre of the multi-dimensional impact of the COVID-19 pandemic, the shortage of medical supplies in countries with weaker healthcare systems significantly reduced the effectiveness of national and international public health interventions. Using a database of test-kit trade flows and barriers, we estimate the price responsiveness of test-kit demand in a global sample of countries. These estimates allow us to investigate the degree to which import tariffs by leading producers could result in a disruption in global supply chains, price increases, and welfare loss.

Breeding custom-designed crops for improved drought adaptation.

The current pace of crop improvement is inadequate to feed the burgeoning human population by 2050. Higher, more stable, and sustainable crop production is required against a backdrop of drought stress, which causes significant losses in crop yields. Tailoring crops for drought adaptation may hold the key to address these challenges and provide resilient production systems for future harvests.

A benefit-cost analysis of different response scenarios to COVID-19: A case study.

Background: This paper compares the direct benefits to the State of Western Australia from employing a "suppression" policy response to the COVID-19 pandemic rather than a "herd immunity" approach.

Methods: An S-I-R (susceptible-infectious-resolved) model is used to estimate the likely benefits of a suppression COVID-19 response compared to a herd immunity alternative. Direct impacts of the virus are calculated on the basis of sick leave, hospitalizations, and fatalities, while indirect impacts related to response actions are excluded.

Hepascore predicts liver outcomes and all-cause mortality in long-term methotrexate users: A retrospective cohort study.

Background And Aim: Methotrexate (MTX) is routinely used for immunological disorders, and its long-term use is associated with hepatotoxicity. The aim of this study was to investigate whether a serum liver fibrosis test (Hepascore) predicted the risk of adverse liver-related outcomes and mortality.

Methods: A total of 92 patients in Western Australia who had a long-term MTX intake history,from 2004 to 2016, were recruited and followed up from the first Hepascore to death or end of the study.

Phenotypic plasticity of four Chenopodiaceae species with contrasting saline-sodic tolerance in response to increased salinity-sodicity.

It is unknown whether phenotypic plasticity in fitness-related traits is associated with salinity-sodicity tolerance. This study compared growth and allocation phenotypic plasticity in two species with low salinity-sodicity tolerance ( and ) and two species with high salinity-sodicity tolerance ( and ) in a pot experiment in the Songnen grassland, China. While the species with low tolerance had higher growth and allocation plasticity than the highly tolerant species, the highly tolerant species only adjusted their growth traits and maintained higher fitness (e.

overcomes natural immunity in repeated infections.

Repeated experimental reinfection of two subjects indicates that infection does not promote an immune response protective against future reinfection. Our results highlight the importance of preventing reinfection after eradication, through public health initiatives, and possibly treatment of family members. They indicate difficulties for vaccine development, especially therapeutic vaccines.

The umbilical vein in the human fetus has a non-linear growth pattern across gestation.

Introduction And Objectives: Estimation of the umbilical venous blood flow volume relies on the diameter of the vein, which has been reported to be reduced in severely growth restricted fetuses. However, there is only limited information on the growth pattern of this vessel in the normal human fetus. The aim of this study is to examine the growth pattern of the umbilical vein across gestation in low-risk human pregnancies.

Disentangling vegetation diversity from climate-energy and habitat heterogeneity for explaining animal geographic patterns.

Broad-scale animal diversity patterns have been traditionally explained by hypotheses focused on climate-energy and habitat heterogeneity, without considering the direct influence of vegetation structure and composition. However, integrating these factors when considering plant-animal correlates still poses a major challenge because plant communities are controlled by abiotic factors that may, at the same time, influence animal distributions. By testing whether the number and variation of plant community types in Europe explain country-level diversity in six animal groups, we propose a conceptual framework in which vegetation diversity represents a bridge between abiotic factors and animal diversity.
