Objectives: We aimed to map the correlation between thermoluminescent dosimeters (TLDs) and Gafchromic film for measuring absorbed doses and to compare minimum, maximum, and mean absorbed doses over larger regions of interest and at various craniofacial organs and tissues during cone beam computed tomography (CBCT) exposure of the mandibular third molar region. Study Design: We positioned TLDs at
Objectives: To analyze the accumulated fees connected with root filling, permanent coronal restoration and follow-on treatment charged by Swedish dentists over a 10–11-year follow-up period. Furthermore, analyzing these fees with reference to the type of restoration, tooth group, and the root-filled teeth which survived compared to those requiring extraction. Material and Methods: In 2009, the dat
BACKGROUND: Postmastectomy radiotherapy was shown in previous meta-analyses to reduce the risks of both recurrence and breast cancer mortality in all women with node-positive disease considered together. However, the benefit in women with only one to three positive lymph nodes is uncertain. We aimed to assess the effect of radiotherapy in these women after mastectomy and axillary dissection.METHOD
Receptor tyrosine kinase KIT is frequently activated in acute myeloid leukemia (AML). While high PRL2 (PTP4A2) expression is correlated with activation of SCF/KIT signaling in AML, the underlying mechanisms are not fully understood. We discovered that inhibition of PRL2 significantly reduces the burden of oncogenic KIT-driven leukemia and extends leukemic mice survival. PRL2 enhances oncogenic KIT
Background: Factors that influence outcomes of interdisciplinary pain rehabilitation programs (IPRP) are poorly known. It is unclear how outcomes are influenced by pain intensity, psychological distress, and coping strategies. Aim: This clinical registry-based longitudinal cohort study has three aims: 1) to determine the relative importance of pain intensity, psychological distress, acceptance, an
A search for exotic decays of the Higgs boson H into new scalar or pseudoscalar particles that subsequently decay into b-quarks is presented. The search considers ZH production with several decay scenarios for the Higgs boson; first to a pair of identical scalars, H → 2a → 4b, second to a pair of scalars with different masses (ma1 < ma2), either directly, H → a1a2 → 4b, or via a longer decay chain
CVD (chemical vapor deposition) coated cutting tools typically exhibit thermal cracks caused by the mismatch in coefficients of thermal expansion (CTEs) between coating and cemented carbide. These cracks act as weak points during stainless steel machining, contributing to premature tool wear. As a strategy to suppress thermal cracks formation, we investigate replacing the conventional cemented car
Purpose: Radiotherapy (RT) for patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC) can be intensified by delivering 6 (6fx/w) instead of 5 (5fx/w) fractions per week. Randomized trials have demonstrated superiority for 6fx/w in patients treated without concurrent chemotherapy (CRT). This real-world analysis compares 6 vs 5 fx/w in LA-HNSCC all-comers, treated predominan
Hydroxyl radicals (HO•), produced through reactions between H2O2 and iron oxides, drive biogeochemical transformations, mediate organism toxicity, and facilitate advanced oxidation processes. The effectiveness of these processes depends on the spatial proximity between HO• generation and target substrates. Consequently, the oxidation mechanisms should be governed by interfacial interactions among
Background: The routine use of sedation and analgesia during post-cardiac arrest care and its association with clinical outcomes remain unclear. This study aimed to describe the use of sedatives and analgesics in post-cardiac arrest care, and evaluate associations with good functional outcome, survival, clinical seizures, and late awakening. Methods: This was a post hoc analysis of the TTM2-trial,
Hair analysis has been used in the past as a method to explore environmental exposure to chemicals, toxins or drug ingestion, with wide applications in forensic science, environmental studies, anthropology and medicine. Although not a conventional sample type, hair offers significant advantages over traditional biospecimens, such as blood or urine. These include its stability, non-invasive nature
FLT3 is a critical prognostic marker in acute myeloid leukemia (AML) due to its high frequency of mutation. Primary mutations in FLT3 include point mutations or deletions in the tyrosine kinase domain (TKD) and internal tandem duplications (ITD) in the juxtamembrane (JM) region. These mutations lead to ligand-independent activation, disrupting the JM region and kinase domain interaction, resulting
Large igneous provinces (LIPs) are excellent spatial and temporal geological recorders. However, our understanding of LIPs is hindered by a lack of preservation and alteration of many LIPs through deep time. Several LIPs have been emplaced in the Rhyacian. These LIPs demonstrate a connection across the Superior, Wyoming and North Atlantic cratons. In this study we use new U-Pb ID-TIMS baddeleyite
Viral hepatitis remains a global health concern, with growing recognition of the impact of hepatitis A virus (HAV), hepatitis E virus (HEV), and herpesvirus-associated hepatitis, particularly in vulnerable groups. This narrative review from the ESCMID Study Group for Viral Hepatitis (ESGVH) summarizes recent advances and expert perspectives. For HAV, insights into viral evolution, epidemiology, an
Hair can record chemical information reflecting our living conditions, and, therefore, strands of hair have become a potent analytical target within the biological and forensic sciences. While early efforts focused on analyzing complete hair strands in bulk, high spatial resolution mass spectrometry imaging (MSI) has recently come to the forefront of chemical hair-strand analysis. MSI techniques o
This paper presents a search for hypothetical massive, charged, long-lived particles with the ATLAS detector at the LHC using an integrated luminosity of 139 fb−1 of proton–proton collisions at s = 13 TeV. These particles are expected to move significantly slower than the speed of light and should be identifiable by their high transverse momenta and anomalously large specific ionisation losses, dE
Results of a search for new phenomena in events with large missing transverse momentum and a Higgs boson decaying to two photons are reported. Data from proton-proton collisions at a center-of-mass energy of 8 TeV and corresponding to an integrated luminosity of 20.3 fb(-1) have been collected with the ATLAS detector at the LHC. The observed data are well described by the expected standard model b
