A phylogenetic approach to delimitate species in a probabilistic way.

Different species concepts and their associated criteria have been used to delimit species boundaries, such as the absence of gene flow for the biological species concept and the presence of morphological distinction for the morphological species concept. The need for different delimitation criteria largely reflects the fact that species are generated under various speciation mechanisms. A key question is how to make species delimitation consistent in a species group, especially when we want to delimit the species boundaries over many newly discovered evolutionary lineages and add these new lineages into a comparative analysis.

The genus Nocardia as a source of new antimicrobials.

The genus Nocardia comprises over 130 species of soil-dwelling actinomycetes, many of which are opportunistic pathogens. Beyond their pathogenicity, Nocardia exhibits significant biosynthetic potential, producing an array of diverse antimicrobial secondary metabolites. This review highlights notable examples of these compounds and explores modern approaches to unlocking their untapped biosynthetic potential.

The endothelial surface layer-glycocalyx - Universal nano-infrastructure is fundamental to physiology, cell traffic and a complementary neural network.

The glycocalyx and its associated endothelial surface layer which lines all cell membranes and most tissues, dwarfs the phospholipid membrane of cells in extent. Its major components are sulphated polymers like heparan and chondroitin sulphates and hyaluronic acid. These form a fuzzy layer of unknown structure and function.

Objectives: Health and social service research impact analysis play a pivotal role in demonstrating research value. Impact analysis of programs, interventions, or policies in real-world settings is complex. There are many implementation evaluation theories, models, and frameworks (TMF) and researchers find choosing one challenging.

Revisiting the electrophysiological correlates of valence and expectancy in reward processing - A multi-lab replication.

Two event-related brain potential (ERP) components, the frontocentral feedback-related negativity (FRN) and the posterior P300, are key in feedback processing. The FRN typically exhibits greater amplitude in response to negative and unexpected outcomes, whereas the P300 is generally more pronounced for positive outcomes. In an influential ERP study, Hajcak et al.

Was extinction of New Zealand's avian megafauna an unavoidable consequence of human arrival?

Human overexploitation contributed strongly to the loss of hundreds of bird species across Oceania, including nine giant, flightless birds called moa. The inevitability of anthropogenic moa extinctions in New Zealand has been fiercely debated. However, we can now rigorously evaluate their extinction drivers using spatially explicit demographic models capturing species-specific interactions between moa, natural climates and landscapes, and human colonists.

Outcomes of surgically treated posterior pelvic fractures in an Australian population: A multicenter study.

Background: Unstable posterior pelvic-ring fractures are rare and difficult to manage. There are many injury patterns, they are associated with high morbidity and mortality, and optimal surgical management remains contentions. This study aims to compare outcomes and complications for different surgical management of these injuries.

"When People Reach Out that is When They're Desperate": Understanding Informal and Formal Help-Seeking Practices for Gambling among Aboriginal Peoples in the Northern Territory, Australia.

This study provides an in-depth qualitative exploration of Aboriginal peoples' experiences with seeking help for gambling-related issues in the Northern Territory (NT), Australia. Through semi-structured interviews with 29 participants, including regular and occasional gamblers as well as those affected by others' gambling, the research highlights key barriers to seeking formal help. These barriers included the normalisation of gambling within Aboriginal communities, denial of gambling problems, feelings of shame, privacy concerns, and a lack of trust in mainstream services.

Each hour injures, the last one kills.

The haemorrhage of psychiatrists from the NSW state-funded mental health system parallels losses throughout Australia, and internationally. The lack of workforce cripples the capacity to provide adequate care. There has been persistently neglectful under-resourcing of the care of people with severe mental illness.

Bio-derived flame retardants are gaining attention as environmentally friendly additives due to their low ecological impact and decreasing costs. These compounds can enhance char formation in polymeric materials by swelling upon heating, attributed to their functional groups.

Label-Free Surface-Enhanced Raman Scattering for Genomic DNA Cytosine Methylation Reading.

DNA methylation has been widely studied with the goal of correlating the genome profiles of various diseases with epigenetic mechanisms. Multiple approaches have been developed that employ extensive steps, such as bisulfite treatments, polymerase chain reactions (PCR), restriction digestion, sequencing, mass analysis, etc., to identify DNA methylation.

The Role of Polarizability in Isoelectronic Ions: The Case of Pseudohalides.

Specific ion effects are widespread and have been studied for over a century, yet they remain poorly understood. Terms like "kosmotropes" and "chaotropes" are convenient rules of thumb but the frequent reversal of the Hofmeister series implies their limitations. Polarizability is often used to classify ions, with kosmotropes considered low in polarizability and chaotropes high.

Deciphering the Complexities of Adult Human Steady State and Stress-Induced Hematopoiesis: Progress and Challenges.

Human hematopoietic stem cells (HSCs) have traditionally been viewed as self-renewing, multipotent cells with enormous potential in sustaining essential steady state blood and immune cell production throughout life. Indeed, around 86% (10-10) of new cells generated daily in a healthy young human adult are of hematopoietic origin. Therapeutically, human HSCs have contributed to over 1.

Jun, an Oncological Foe or Friend?

Jun/JUN is a basic leucine zipper (bZIP) protein and a prototypic member of the activator protein-1 (AP-1) family of transcription factors that can act as homo- or heterodimers, interact with DNA elements and co-factors, and regulate gene transcription. Jun is expressed by both immune and inflammatory cells. Jun is traditionally seen as an oncoprotein that regulates processes involved in transformation and oncogenesis in human tumours.

Exploring the Potential of Genome-Wide Hybridization Capture Enrichment for Forensic DNA Profiling of Degraded Bones.

Unlabelled: In many human rights and criminal contexts, skeletal remains are often the only available samples, and they present a significant challenge for forensic DNA profiling due to DNA degradation. Ancient DNA methods, particularly capture hybridization enrichment, have been proposed for dealing with severely degraded bones, given their capacity to yield results in ancient remains.

Background/objectives: This paper aims to test the efficacy of genome-wide capture enrichment on degraded forensic human remains compared to autosomal STRs analysis.

The Persistence of Antibiotic Resistance in Observational Studies: Is It Really Due to Differences in Sub-Populations Rather than Antibiotic Use?

: The carriage of resistant bacteria and prior antimicrobial treatment are related, but in an individual, this diminishes over time. To better manage antimicrobial resistance risks, it is crucial that we better untangle any lasting impact of antibiotic use compared to other factors. This understanding is essential for informing antimicrobial stewardship programs and to better manage other important factors that likely contribute to persistently higher rates of antimicrobial resistance in different populations.

Remediating Cambridge: Human and Horse Co-Relationality in a Culture of Mis-Re-Presentation.

This case study aims to problematise concepts of equine and human co-relational agency in the context of 'mis-re-presentations' in the Australian media of harms experienced by the Anglo Arab stallion, Cambridge, following his development of laminitis and his consequent confinement at a leading national Equestrian centre. Autoethnographic narrative is used to retrospectively and selectively narrate the evolving relationship between Cambridge and his owners, farrier, and treating veterinarians within the dominant housing and veterinary practices and welfare paradigms in equestrian culture of 1990's Australia. Structured author/owner autoethnographic vignettes are framed by newspaper and internet reportage to highlight a productive tension between the public mediation of the case, and what it means to be fully embodied in relationship with an equine companion agent within a particular, racialised, gendered, and biopoliticised location.

The safety and efficacy of cannabinoids for the treatment of mental health and substance use disorders: protocol for a systematic review and meta-analysis.

There has been a global increase in the use of cannabinoids as a treatment for mental health (MH) and substance use disorders (SUD). In 2016, an Australian government-funded review found that although medicinal cannabinoids accounted for a small reduction in MH symptoms, the results varied according to study design. There has since been a rise in randomised controlled trials (RCTs) aiming to examine the efficacy of cannabinoids for the treatment of MH and SUD.

Ten pressure points in primary care during COVID-19: findings from an international narrative review.

Background: Strong primary care (PC) services are the foundation of high-performing health care systems and can support effective responses to public health emergencies. Primary care practitioners (PCPs) and PC services played crucial roles in supporting global health system responses to the COVID-19 pandemic. However, these contributions have come at a cost, impacting on PC services and affecting patient care.

Oculomotor Function in Children and Adolescents with Autism, ADHD or Co-occurring Autism and ADHD.

Oculomotor characteristics, including accuracy, timing, and sensorimotor processing, are considered sensitive intermediate phenotypes for understanding the etiology of neurodevelopmental conditions, such as autism and ADHD. Oculomotor characteristics have predominantly been studied separately in autism and ADHD. Despite the high rates of co-occurrence between these conditions, only one study has investigated oculomotor processes among those with co-occurring autism + ADHD.

Antimicrobial Resistance in Curable Sexually Transmitted Infections.

Purpose Of Review: Antimicrobial resistance in sexually transmitted infections (STIs) has become an urgent global public health threat, raising the specter of untreatable infections. This review summarizes the determinants of resistance among the five most common curable STIs Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium, Treponema pallidum, and Trichomonas vaginalis, as well as strategies to mitigate the spread of resistance.

Recent Findings: Genetic mutations are key drivers of resistance for N.

Diagnostic yield of cystic fibrosis from a South Australian monocentric cohort: a retrospective study.

Objectives: To determine the diagnostic yield of cystic fibrosis (CF) using a two-tiered genetic testing approach. Although newborn screening includes CF, this typically only covers a selection of common genetic variants, and with over 2000 reported in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, we hypothesised that patients will be missed and present clinically later in life.

Design: A retrospective study over a 5-year period (January 2018-December 2022).
