Wildland Firefighters Suffer Increasing Risk of Job-Related Death.

Wildland firefighting is a niche specialization in the fire service - inherently dangerous with unique risks. Over the past decade, fatalities amongst all firefighters have decreased; however, wildland firefighter fatalities have increased. This subject has only been described in the grey literature, and a paucity of medical literature exists.

Ultrafast Charge Carrier Dynamics in Vanadium Dioxide, VO: Nonequilibrium Contributions to the Photoinduced Phase Transitions.

Vanadium oxide (VO) is an exotic phase-change material with diverse applications ranging from thermochromic smart windows to thermal sensors, neuromorphic computing, and tunable metasurfaces. Nonetheless, the mechanism responsible for its metal-insulator phase transition remains a subject of vigorous debate. Here, we investigate the ultrafast dynamics of the photoinduced phase transition in VO under low perturbation conditions.

Ablation of LRP6 in alpha-smooth muscle actin-expressing cells abrogates lung inflammation and fibrosis upon bleomycin-induced lung injury.

Tissue fibrosis is a progressive pathological process with excessive deposition of extracellular matrix proteins (ECM). Myofibroblasts, identified by alpha-smooth muscle actin (αSMA) expression, play an important role in tissue fibrosis by producing ECM. Here, we found that the Wnt antagonist Dickkopf1 (DKK1) induced gene expressions associated with inflammation and fibrosis in lung fibroblasts.

Inhibition of HMGA2 binding to AT-rich DNA by its negatively charged C-terminus.

The mammalian high mobility group protein AT-hook 2 (HMGA2) is a small DNA-binding protein that specifically targets AT-rich DNA sequences. Structurally, HMGA2 is an intrinsically disordered protein (IDP), comprising three positively charged 'AT-hooks' and a negatively charged C-terminus. HMGA2 can form homodimers through electrostatic interactions between its 'AT-hooks' and C-terminus.

An Introduction to the Complete Blood Count for Clinical Chemists: White Blood Cells.

Background: The most frequently ordered laboratory test worldwide is the complete blood count (CBC). As clinical chemists are increasingly assigned to assist or direct laboratories outside of the traditional clinical chemistry sections, such as the automated hematology section, expertise must be established. This review article is a dedication to that ongoing effort.

Structural Changes in Atomically Precise Ag Nanoclusters upon Sequential Attachment and Detachment of Secondary Ligands.

Elucidating the structural dynamics of ligand-stabilized noble metal nanoclusters (NCs) is critical for understanding their properties and for developing applications. Ligand rearrangement at NC surfaces is an important contributor to structural change. In this study, we investigate the dynamic behavior of ligand-protected [Ag(L)] NC's (L = 1,3-benzenedithiol) interacting with secondary ligand 2,2'-[1,4-phenylenebis (methylidynenitrilo)] bis[benzenethiol] (referred to as ).

Women Ridesharing Drivers' Responses to Sexual Violence on the Job: The Role of Confrontation.

One critical area where sexual violence has been underexplored is in the ridesharing industry in the United States, where women drivers frequently must interact with unknown male passengers. Sexual violence against them is categorized as technology-facilitated gender-based violence in the online to offline world, where services such as transportation are ordered through an online app and result in a person-to-person interaction once the driver picks the passenger up. Since ridesharing drivers are mostly independent contractors, they do not have at their disposal traditional legal and strong organizational remedies to address sexual violence; moreover, like all victims of violence, these methods usually can only be accessed after the incident has taken place.

Is the Victimization-Perpetration Association for School Bullying a Cycle of Bias?

It is well known that some youth are both victims and perpetrators of bullying. However, it remains unclear whether the victim-perpetrator overlap contains specific characteristics, such as bias. Using data from the United States Health Behavior among School-aged Children survey from 2009 to 2010 ( = 8,739), this study investigated the victim-perpetrator overlap for school bullying, with emphasis on assessing whether the perpetrators of biased (i.

Nurse Perspectives on Labor Union Participation Prior to Implementation of a Collective Bargaining Agreement: A Qualitative Study.

Patient advocacy is a duty for professional nurses; however, not all nurses are empowered to advocate for meeting patients' needs. Participation in labor unions may serve as a venue for nurses with limited institutional decision-making authority to advocate for patient needs; however, unionization can be a time-intensive and fraught process. This study examined how nurses participating in a new union in an urban United States hospital described their reasons for participating in a labor union during collective bargaining.

Identification of a TNIK-CDK9 axis as a targetable strategy for platinum-resistant ovarian cancer.

Up to 90% of high-grade serous ovarian cancer (HGSC) patients will develop resistance to platinum-based chemotherapy, posing substantial therapeutic challenges due to a lack of universally druggable targets. Leveraging BenevolentAI's AI-driven approach to target discovery, we screened potential AI-predicted therapeutic targets mapped to unapproved tool compounds in patient-derived 3D models. This identified TNIK, which is modulated by NCB-0846, as a novel target for platinum-resistant HGSC.

Economic impact associated with dronedarone use in patients with atrial fibrillation.

Objective/AimIn 2009, dronedarone was approved by the United States Food and Drug Administration based on results from the ATHENA trial (NCT00174785), which showed significant reduction of cardiovascular (CV) hospitalization and death in patients with atrial fibrillation (AF) randomized to dronedarone versus placebo. In 2020, a retrospective study by Goehring et al. showed CV hospitalizations and deaths were lower in clinical practice following initiation of dronedarone compared to other antiarrhythmic drugs (AADs) in patients with AF and atrial flutter.

Association of Hospital Consolidation with Cancer Outcomes.

Hospital mergers have increased significantly since 2010, driven by factors such as healthcare policy changes, reimbursement, economies of scale, and quality improvement goals. However, limited evidence exists about how these mergers affect the quality of care and cancer outcomes. We conducted a difference-in-differences analysis to assess the impact of hospital consolidation on cancer outcomes.

Review of Associations of Diabetes and Insulin Resistance With Brain Health in Three Harmonised Cohort Studies of Ageing and Dementia.

Diabetes increases the risk of dementia, and insulin resistance (IR) has emerged as a potential unifying feature. Here, we review published findings over the past 2 decades on the relation of diabetes and IR to brain health, including those related to cognition and neuropathology, in the Religious Orders Study, the Rush Memory and Aging Project, and the Minority Aging Research Study (ROS/MAP/MARS), three harmonised cohort studies of ageing and dementia at the Rush Alzheimer's Disease Center (RADC). A wide range of participant data, including information on medical conditions such as diabetes and neuropsychological tests, as well as other clinical and laboratory-based data collected annually.

Subventricular Accumulation of Cu in the Aging Mouse Brain Does Not Associate with Anticipated Increases in Markers of Oxidative Stress.

Natural aging is associated with mild memory loss and cognitive decline, and age is the greatest risk factor for neurodegenerative diseases, such as Alzheimer's disease. There is substantial evidence that oxidative stress is a major contributor to both natural aging and neurodegenerative disease, and coincidently, levels of redox active metals such as Fe and Cu are known to be elevated later in life. Recently, a pronounced age-related increase in Cu content has been reported to occur in mice and rats around a vital regulatory brain region, the subventricular zone of lateral ventricles.

Using Community Composition and Successional Theory to Guide Site-Specific Coral Reef Management.

High spatial or temporal variability in community composition makes it challenging for natural resource managers to predict ecosystem trajectories at scales relevant to management. This is commonly the case in nearshore marine environments, where the frequency and intensity of disturbance events vary at the sub-kilometer to meter scale, creating a patchwork of successional stages within a single ecosystem. The successional stage of a community impacts its stability, recovery potential, and trajectory over time in predictable ways.

Polarization-Independent High-Q Phase Gradient Metasurfaces.

Dielectric metasurfaces have emerged as an unprecedented platform for precise wavefront manipulation at subwavelength scales with nearly zero loss. When aiming at dynamic applications such as AR/VR and LiDAR, high-quality factor (high-Q) phase gradient metasurfaces have emerged as a way to boost weak light-material interactions in flat-optical components. However, resonant features are naturally tied to polarization, limiting devices to operating on a single polarization state, which reduces the efficiency and adaptability of wave-shaping.

Chemical Redox Agent-Driven Noncorrosive Formation of Nanoporous Mg Structures for Advanced Hydrogen Storage.

Light metal-based nanomaterials are widely used for energy storage due to their high energy density and surface-to-volume ratio. However, their high reactivity is paradoxically both the source of advantageous properties and a hurdle to the fabrication of stable nanostructures. Here, we demonstrate the formation of nanoporous Mg via chemical redox agent-driven dealloying, which ensures minimized surface passivation and results in fine nanostructures with <50 nm of interconnected metallic ligament despite the labile chemical properties of Mg.

Improving osteogenic properties of zirconia ceramic via glow discharge plasma-enhanced deposition of amine organic compound.

Background/purpose: Osseointegration potential is greatly depended on the interaction between bone cells and dental implant surface. Since zirconia ceramic has a bioinert surface, functionalization of the surface with an organic compound allylamine was conducted to overcome its drawback of minimal interaction with the surrounding bone.

Materials And Methods: The zirconia surface was initially treated with argon glow discharge plasma (GDP), then combined with amine plasma at three different conditions of 50-W, 75-W and 85-W, to prepare the final samples.

Comparative transcriptomic rhythms in the mouse and human prefrontal cortex.

Introduction: Alterations in multiple subregions of the human prefrontal cortex (PFC) have been heavily implicated in psychiatric diseases. Moreover, emerging evidence suggests that circadian rhythms in gene expression are present across the brain, including in the PFC, and that these rhythms are altered in disease. However, investigation into the potential circadian mechanisms underlying these diseases in animal models must contend with the fact that the human PFC is highly evolved and specialized relative to that of rodents.
