How Pseudomonas conducts reductive dechlorination of 2,4,6-trichlorophenol: Insights into metabolic performance and organohalide respiration process.

Organohalide-respiring bacteria (OHRB) play a key role in facilitating the detoxification of halogenated organics, but their slow growth and harsh growth conditions often limit their application in field remediation. In this study, we investigated the metabolic performance and organohalide respiration process of a non-obligate OHRB, Pseudomonas sp. CP-1, demonstrating favorable anaerobic reductive dechlorination ability of 2,4,6-trichlorophenol to 4-chlorophenol with a removal rate constant (k) of 0.

Methods: We conducted a systematic literature search from January 1, 2000, to November 6, 2024, across databases like PubMed, MEDLINE and EMBASE, Web of Science, and Scopus, focusing on observational studies that quantitatively defined extreme temperatures and their impacts on COPD morbidity and mortality. Out of 3140 records, 25 studies met the inclusion criteria.

Exploring the development of pedagogical content knowledge (PCK) for health professions educators through faculty development.

Research on how pedagogical content knowledge (PCK)-informed faculty development initiatives can support PCK development among health professions educators is limited. Given the positive impact of PCK on enhancing professional knowledge for effective teaching, this study investigates the learning process of health professions educators in developing their PCK through a faculty development initiative, supported by the Content Representation (CoRe) tool. Using a qualitative approach, grounded in social constructionism, the study engaged eight educators from diverse health disciplines at an Australian university.

The Validation of the Sinclair Compassion Questionnaire (SCQ) and SCQ Short Form in an English-Speaking U.S. Population: A Patient-Reported Measure of Compassion in Healthcare.

Compassion is recognized as a key component of high-quality healthcare. The literature shows that compassion is essential to improving patient-reported outcomes and fostering health care professionals' (HCPs) response and resilience to burnout. However, compassion is inherently difficult to define, and a validated tool to reliably quantify and measure patients' experience of compassion in healthcare settings did not exist until recently.

Hydrodilatation: a comparison between diabetics and non-diabetics with adhesive capsulitis.

Purpose: The primary aim of this retrospective study is to compare the short and medium-term outcomes for shoulder hydrodilatation for treatment of shoulder AC between diabetic and non-diabetic patients, to evaluate if there were better outcomes amongst non-diabetic patients.

Methods: Patients with clinical or radiological diagnosis of AC and who underwent fluoroscopic guided shoulder hydrodilatation in our local institution from January 2021 to June 2022 were included in this study. Clinical outcomes were measured with visual analog scale (VAS) for pain and passive range of motion consisting of forward flexion (FF) and external rotation (ER) at pre-hydrodilatation, one month and six months post hydrodilatation.

Pre-operative imaging for inguinal hernia: routine or waste? A single institution perspective.

Introduction: Inguinal hernia is a very common surgical problem in Australia. This study aims to assess at a single institution the perioperative use of imaging for these patients, and the accuracy of that imaging.

Methods: Data were collected retrospectively for 215 adult patients who underwent inguinal hernia repair at a single public hospital.

Haematological setpoints are a stable and patient-specific deep phenotype.

The complete blood count (CBC) is an important screening tool for healthy adults and a common test at periodic exams. However, results are usually interpreted relative to one-size-fits-all reference intervals, undermining the precision medicine goal to tailor care for patients on the basis of their unique characteristics. Here we study thousands of diverse patients at an academic medical centre and show that routine CBC indices fluctuate around stable values or setpoints, and setpoints are patient-specific, with the typical healthy adult's nine CBC setpoints distinguishable as a group from those of 98% of other healthy adults, and setpoint differences persist for at least 20 years.

Explainable AI and trust: How news media shapes public support for AI-powered autonomous passenger drones.

This study delves into the intricate relationships between attention to AI in news media, perceived AI explainability, trust in AI, and public support for autonomous passenger drones. Using structural equation modelling ( = 1,002), we found significant associations between perceived AI explainability and all trust dimensions (i.e.

Unraveling chained optimization strategies for carbon emission control in WWTPs and effective water utilization within complicated water systems.

China faces severe water scarcity and significant greenhouse gas (GHG) emission pressures. As significant sources of GHG emission within urban system, wastewater treatment plants (WWTPs) exhibit a clear coupling relationship between wastewater treatment and urban water usage. However, the lack of trace of the water‑carbon nexus has created an obstacle to coordinating water utilization strategies and low-carbon wastewater treatment.

Nitrogen metabolic responses of non-rhizosphere and rhizosphere microbial communities in constructed wetlands under nanoplastics disturbance.

Constructed wetlands (CWs) serve as crucial sinks for nanoplastics, making them a significant research hotspot regarding the impacts of nanoplastics on the nitrogen metabolism within microbial communities. However, there has been a lack of comparative analysis between rhizosphere and non-rhizosphere microbial communities under nanoplastics disturbance. This study analyzes the nitrogen metabolic responses of these microbial communities in CWs following repeated nanoplastics disturbance.

Methods: Data were sourced from diverse population-wide datasets including government reports and public hospital records.

Genomics identifies koala populations at risk across eastern Australia.

Koalas are an iconic, endangered, Australian marsupial. Disease, habitat destruction, and catastrophic mega-fires have reduced koalas to remnant patches of their former range. With increased likelihood of extreme weather events and ongoing habitat clearing across Australia, koala populations are vulnerable to further declines and isolation.

Sulfur-species in Zinc-specific Condylar Zones of a Rat Temporomandibular Joint.

In this study, we performed synchrotron-based micro-X-ray fluorescence (μ-XRF) imaging of elements Zn and S, and X-ray absorption near edge spectroscopy (XANES) coupled with μ-XRF for identification of Zn and S species in the condylar zones of a rat temporomandibular joint (TMJ). Histologic localization of Zn and hypoxia-inducible factor-1α (HIF-1α) were mapped using an optical microscope. These data were visually correlated with μ-XRF and XANES data to provide insights into plausible biological S-species in Z-enriched condylar zones of a rat TMJ.
