Background/Objectives: Root canal instrumentation has a crucial role in the success of endodontic treatment. However, management of curved root canals remains a challenge. This study aimed to compare the performance of four rotatory file systems, ProTaper Next, TruNatomy, ProTaper Ultimate and Race Evo, in terms of wear, transportation and centering capacity, in curved root canals. Methods: A total of 150 human tooth roots were selected, divided based on the degree of curvature, and then...

Deep-seated partisan animosity and aversion present challenges across the global political landscape, yet little is known about how individuals perceive the climate of polarization in their societies or the broader societal conditions that shape these perceptions. Drawing on a dataset spanning 44 countries (N = 8917), we examined how macro-level indicators of dysfunction and disruption relate to the perceived climate of polarization - that is, the degree to which people believe major voter...

An estimated 50% to 75% of patients with mild traumatic brain injury (mTBI) report chronic pain. Symptomatology evolution, subtypes, and risk factors remain poorly understood. We evaluated patient-reported pain intensity and interference with daily function in a longitudinal U.S. mTBI cohort. The Transforming Research and Clinical Knowledge in Traumatic Brain Injury Study prospectively enrolled patients with TBI across 18 trauma centers who received head computed tomography (CT) within 24 hours...

Attention deficit hyperactivity disorder (ADHD) occurs in 9.8% of U.S. children and has a large hereditary component arising from multiple gene variants. One of these is Latrophiln-3 (LPHN-3). Using CRISPR/Cas9 we deleted exon 3 in Sprague Dawley rats to create a global Lphn3 knockout (gKO). The gKO rats are hyperactive, startle hyper-reactive, impulsive, and have impaired working, spatial, and egocentric learning and memory. Permethrin (PRM) is a widely used pyrethroid insecticide. Acute...

BACKGROUND: Hospitalizations for acute bacterial and fungal infections related to injection drug use are increasing in the background of the United States drug overdose crisis. These infections are a significant contributor to morbidity and mortality among people who inject drugs (PWID). Currently, limited comprehensive approaches to caring for PWID hospitalized with severe injection-related infections (SIRIs) exist. We developed a multidisciplinary model integrating infectious disease (ID),...

Compromised bone marrow niches following irradiation limit hematopoietic stem cell transplantation (HSCT) success by delaying immune reconstitution. Strategies to rebuild functional marrow environments are essential to support hematopoietic stem cell (HSC) maintenance. However, the fundamental relationship between bone formation and bone marrow niche development, and how these processes are modulated by key biological variables, remains poorly understood. Here, we present an alginate-gelatin...

CONCLUSION: MC remained the preferred modality for treating both unruptured and ruptured MCAb aneurysms, demonstrating superior immediate and final angiographic occlusion rates with minimal intraoperative and postoperative complications. SAC showed similar safety but was technically more challenging, FD had higher ischemic event rates, and SC had more delayed reruptures.

In contrast to living organisms, viruses were long thought to lack protein synthesis machinery and instead depend on host factors to translate viral transcripts. Here, we discover that giant DNA viruses encode a distinct and functional IF4F translation-initiation complex to drive protein synthesis, thereby blurring the line between cellular and acellular biology. During infection, eukaryotic IF4F on host ribosomes is replaced by an essential viral IF4F that regulates viral translation, virion...

CONCLUSION: Pipeline, SVB, and FRED Jr. FDs show similar safety and efficacy for unruptured DACA aneurysms. Complete occlusion is influenced by clinical and procedural factors, supporting individualized device selection.

Quantifying sleep quality in rodent models is critical for understanding its impact on neurological health and disease. Piezoelectric cage systems enable rapid, noninvasive measurement of multiple sleep metrics for large sample sizes of rodents. Although sleep duration is commonly reported, sleep fragmentation, which is a key feature of sleep architecture implicated in neurodegenerative disease, circadian rhythm disruption, and injury models, is not directly measured. We developed a standardized...

CONCLUSIONS: Living near a greater number of cannabis dispensaries within 1 mile of home appears to be associated with an increased risk of cannabis use. Web-scraped dispensary sources and United States government-maintained registry lists produce similar conclusions regarding the association of living near a greater number of dispensaries with young adult cannabis use.

INTRODUCTION: Although percutaneous kyphoplasty (PKP) is widely recognized as an effective treatment for osteoporotic vertebral compression fractures (VCFs), there is growing concern about the risk of subsequent VCF after the procedure. Prior studies suggest that the timing between primary VCF and PKP may affect future VCF, but there are limited data evaluating this timing, and no studies use data-driven methods to derive precise thresholds. Therefore, the aim of this study was to determine (1)...

CONCLUSIONS: Ceralasertib monotherapy demonstrated promising anti-tumor activity in ARID1A-deficient gynecologic malignancies. Tumor molecular and immune correlates may inform the further development of ATR inhibitors in this patient population.

CONCLUSIONS: Macroscopic measurements strongly predict histology in SKH1 photocarcinogenesis. Lesions ≥6.3 mm in diameter, ≥4.1 mm in height, or ≥ 46.8 mm³ in volume can be considered cancer with 100% PPV in this dataset. These thresholds provide practical, pathology-anchored endpoints for preclinical study design.

CONCLUSIONS: GA significantly improved successful revascularization rates in patients undergoing EVT. In RCTs that enrolled patients based on established EVT inclusion criteria, the rate of good functional outcome at 90 days was significantly higher in patients undergoing EVT with GA compared with non-GA.

Aggressive B-cell lymphomas, driven by MYC overexpression, exhibit rapid progression, resistance to therapies, and poor survival. While chimeric antigen receptor (CAR)-engineered T cells have demonstrated remarkable clinical efficacy in B-cell lymphomas, nearly half of patients who initially respond to CAR-T therapy eventually develop resistance and disease progression. In this study, we report the presence of residual drug-tolerant persister (DTP) and resistant lymphoma cells remaining within a...

Invasive intracranial pressure (ICP) monitoring is considered the gold standard for the management of patients with an acute brain injury and at risk of developing intracranial hypertension (IH). However, invasive devices (e.g., intraparenchymal probe or external ventricular drain) are expensive, not available worldwide, and might be associated with some risks. Recently, a consensus for the monitoring and management of traumatic brain injury (TBI) patients when invasive ICP is not available...

Death certificates record causes of death as reported by certifiers (Entity Axis) and as standardized by mortality coding rules (Record Axis). Conventional mortality statistics then reduce these to a single underlying cause, ignoring other contributing conditions; weighting schemes can instead distribute the mortality burden across all listed causes. We evaluated the impact of re-classification and weighting across all 56,986,831 US death certificates from 2003-2023, mapping ICD-10 codes to 14...

Programmable A-to-I RNA editing using endogenous ADAR enzymes is emerging as a therapeutic strategy, but editability remains difficult to predict because ADAR recognition depends on double-stranded RNA geometry and stability rather than sequence alone. We present A dar E dit , a structure-explicit graph-attention framework that represents each dsRNA substrate as a nucleotide graph with backbone and base-pair edges and augments this representation with typed interactions and a motif-sensitive...
