Classification and prognostic evaluation of ameloblastoma using multiplanar CT imaging: a retrospective analysis.

Background: Ameloblastoma is the most prevalent odontogenic tumor of the jaw, with a significant recurrence rate. It was conventionally classified radiographically as unilocular or multilocular. As 3D images become more common, there is a need to reassess this classification.

Multimodal treatments and the risk of breast cancer-related lymphedema: insights from a nationally representative cohort in South Korea.

Background: As the roles of chemotherapy (Chemo) and radiation therapy (Radio) in the definitive treatment of breast cancer have expanded, a broader understanding of the factors associated with breast cancer-related lymphedema (BCRL) has become increasingly essential. Therefore, we investigated the association between multimodality treatment and the risk of BCRL.

Methods: In this retrospective study conducted using National Health Insurance data and the Korea National Cancer Incidence Database (2006-2017), 114,638 participants who underwent Surgery (Surg) or Chemo within 6 months after breast cancer diagnosis were enrolled, and the effect of multimodality treatment on the risk of BCRL was analyzed using the Cox proportional-hazards model.

Tousled-like kinase loss confers PARP inhibitor resistance in BRCA1-mutated cancers by impeding non-homologous end joining repair.

Background: Double-strand breaks (DSBs) are primarily repaired through non-homologous end joining (NHEJ) and homologous recombination (HR). Given that DSBs are highly cytotoxic, PARP inhibitors (PARPi), a prominent class of anticancer drugs, are designed to target tumors with HR deficiency (HRD), such as those harboring BRCA mutations. However, many tumor cells acquire resistance to PARPi, often by restoring HR in HRD cells through the inactivation of NHEJ.

Ultrasound evaluation of clinical mimics of deep vein thrombosis: essential insights for radiologists in interpretation.

Ultrasonography (US) is a sensitive and radiation-free technique for diagnosing deep vein thrombosis (DVT). Therefore, when DVT is clinically suspected but not detected on US, radiologists should consider a range of alternative differential diagnoses. This review article presents the imaging findings of clinical conditions that mimic DVT, which can be distinguished using a multimodal radiologic approach.

Shoulder Aesthetics: A Novel Synergy of Hyaluronic Acid Fillers and Neuromodulators.

The pursuit of aesthetically pleasing shoulder contours, particularly those characterised by a sharp, angular definition, has gained significant traction in Southeast Asia. Traditionally, neuromodulators have been used to achieve these results by inducing muscle atrophy, particularly in the trapezius muscles. However, this approach can carry potential risks, such as compromised muscle function and spinal instability.

Genomics yields biological and phenotypic insights into bipolar disorder.

Bipolar disorder is a leading contributor to the global burden of disease. Despite high heritability (60-80%), the majority of the underlying genetic determinants remain unknown. We analysed data from participants of European, East Asian, African American and Latino ancestries (n = 158,036 cases with bipolar disorder, 2.

Depressive intensity, duration, and their associations with cognitive decline: a population-based study in Korea.

Existing epidemiological studies have ignored the effect of depressive duration on cognitive decline despite the presence of biological cues and understudied the depression-cognition association in Asian countries in the context of increasing cognitive burden worldwide. We aimed to comprehensively characterize the effects of depressive duration and intensity on cognitive decline at the population level. A total of 6406 individuals from the Korean Longitudinal Study of Aging (KLoSA) from 2010 to 2018 were included to generate four datasets with durations of 2, 4, 6, and 8 years.

Double-sided van der Waals epitaxy of topological insulators across an atomically thin membrane.

Atomically thin van der Waals (vdW) films provide a material platform for the epitaxial growth of quantum heterostructures. However, unlike the remote epitaxial growth of three-dimensional bulk crystals, the growth of two-dimensional material heterostructures across atomic layers has been limited due to the weak vdW interaction. Here we report the double-sided epitaxy of vdW layered materials through atomic membranes.

Blue photoluminescence from active carboxyl adatoms on nanoporous anodic alumina films.

Nanoporous anodic alumina (nPAA) films formed on aluminum in lower aliphatic carboxylic acids exhibit blue self-coloring and characteristic properties such as photoluminescence (PL), electroluminescence, and electron spin resonance. The blue colors are seemingly originated from the adsorbed radicals incorporating into the oxide during the aluminum anodization. However, there is lack of reports revealing the detailed activation mechanism of the adatoms in the complexes.

Observation of magnetic skyrmion lattice in CrMnGe by small-angle neutron scattering.

Incommensurate magnetic phases in chiral cubic crystals are an established source of topological spin textures such as skyrmion and hedgehog lattices, with potential applications in spintronics and information storage. We report a comprehensive small-angle neutron scattering (SANS) study on the B20-type chiral magnet Cr[Formula: see text]Mn[Formula: see text]Ge, exploring its magnetic phase diagram and confirming the stabilization of a skyrmion lattice under low magnetic fields. Our results reveal a helical ground state with a decreasing pitch from 40 to 35 nm upon cooling, and a skyrmion phase stable in applied magnetic fields of 10-30 mT, and over an unusually wide temperature range for chiral magnets of 6 K ([Formula: see text], [Formula: see text] K).

A systematic review of emergency room laparotomy in patients with severe abdominal trauma.

Traumatic intra-abdominal hemorrhage contributes to mortality in patients with trauma.

A total of 18,994 patients referred to a single reference laboratory for ES between 2020 and 2022 were studied for the diagnostic rate and factors influencing the diagnostic rate. The overall diagnostic rate was 31.

Chemical tools to define and manipulate interferon-inducible Ubl protease USP18.

Ubiquitin-specific protease 18 (USP18) is a multifunctional cysteine protease primarily responsible for deconjugating the interferon-inducible ubiquitin-like modifier ISG15 from protein substrates. Here, we report the design and synthesis of activity-based probes (ABPs) that incorporate unnatural amino acids into the C-terminal tail of ISG15, enabling the selective detection of USP18 activity over other ISG15 cross-reactive deubiquitinases (DUBs) such as USP5 and USP14. Combined with a ubiquitin-based DUB ABP, the USP18 ABP is employed in a chemoproteomics screening platform to identify and assess inhibitors of DUBs including USP18.
