Bilateral periorbital subcutaneous emphysema following Le Fort I osteotomy: a case report

Subcutaneous emphysema is a rare but recognised complication of orthognathic surgery. When it extends to the periorbital region after a Le Fort I osteotomy (LFI), the eyelid swelling can be alarming for the patient and may delay early functional recovery. Periorbital extension an...

Mitigating the impacts of oligotrophication and thermal stress on Pacific oyster Magallana gigas aquaculture through solar-powered artificial upwelling

Abstract Recent oligotrophication and rising water temperatures in the Seto Inland Sea of Japan have led to a decline in oyster production in Hiroshima Prefecture. This study developed and evaluated the “Seawater Pump-up Apparatus for Localized Oceanic Warming-mitigation” (SPALOW...

H‐Likelihood Approach on the Joint Frailty Model for Clustered Bivariate Survival Data

ABSTRACT Recently, clustered bivariate survival data have been extensively studied using different modeling approaches, such as frailty models and copula models. These data can take several forms, including bivariate censored data, semicompeting risks data, and competing risks da...

Prevalence of elevated blood pressure, elevated blood glucose, and cardiometabolic risk factors among rural adults in Chattogram Division, Bangladesh

Non-communicable diseases (NCDs), particularly hypertension and diabetes, represent a growing public health challenge in low- and middle-income countries (LMICs). Comprehensive community-based data on cardiometabolic risk factors among rural adults in Chattogram Division, Banglad...

Effect of Silica-Based Abrasive Ingredients on Fluoride Concentration in Toothpaste: An In Vitro and In Vivo Study

Background/Objectives: Toothpastes have recently been developed with purposes ranging from strengthening teeth and restoring periodontal tissue to removing stains and alleviating tooth sensitivity. Although the individual effects of each component are well understood, their inter...

The parent bodies of Ryugu and Ivuna formed before those of other carbonaceous chondrites

Most carbonaceous chondrite (CC) meteorites contain abundant chondrules, millimeter-scale spherical inclusions of previously molten material. Ivuna-type carbonaceous chondrites (CIs) do not contain chondrules, nor do samples of the carbonaceous asteroid Ryugu. CIs and Ryugu share...

Helical-to-Fan Transitions under Magnetic Fields in the Noncentrosymmetric Tetragonal Magnet EuRhGe 3

The magnetic structure of EuRhGe 3 , a noncentrosymmetric body-centered tetragonal magnet with the space group I4mm, has been investigated by resonant X-ray diffraction. Below T N = 12 K, EuRhGe 3 undergoes a helical magnetic ordering with an incommensurate propagation vector [Fo...

Recent advances in carbon capture and CO 2 valorization for deep decarbonization of the cement sector

Abstract Reducing emissions from the cement industry is essential to limiting global temperature rise below 1.5°C, as the sector accounts for approximately 7% of global CO 2 emissions. This paper reviews carbon capture and utilization as a promising decarbonization strategy for c...

Human-inherited RORγT deficiency encompasses genetic heterogeneity, T cell deficiency, and clinical homogeneity

Abstract We previously reported inherited RORγT deficiency in seven patients from three ancestries (Chilean, Palestinian, Saudi Arabian) with mycobacterial disease and chronic mucocutaneous candidiasis (CMC). We report here five additional patients from different ancestries (Afgh...

The illusion of devolution: Why Sri Lanka's 13th Amendment to the Constitution failed to foster reconciliation

The 13th Amendment to Sri Lanka's Constitution was introduced in 1987 through the Indo-Lanka Accord to resolve ethnic conflict by devolving powers to the Northern and Eastern provinces. However, it failed to deliver societal reconciliation to marginalised communities. This study...

An Improved Rat Model of Myocardial Infarction Without Invasive Intubation

Background/Aim: The standard surgical procedure for inducing myocardial infarction (MI) in rat models via left anterior descending (LAD) coronary artery ligation typically requires invasive endotracheal intubation. While recent techniques have avoided intubation, they necessitate...

Time to metastasis predicts prognosis and improves the Bellmunt score in metastatic urothelial carcinoma

Abstract Prognostic models for metastatic urothelial carcinoma (mUC) have limited accuracy and additional clinically meaningful factors are needed to improve risk stratification. Time to metastasis from initial diagnosis (TTM) is an established prognostic variable in other urolog...

Institutional enrollment volume and clinical outcomes after surgery or chemoradiotherapy for clinical stage I esophageal squamous cell carcinoma: a supplementary analysis of JCOG0502

Abstract Background Surgery and chemoradiotherapy (CRT) are standard options for clinical stage I esophageal squamous cell carcinoma (ESCC). JCOG0502, a multicenter, non-randomized, parallel-group comparison, demonstrated the non-inferiority of definitive CRT compared with surger...

Time-Temperature-Transformation Diagrams to Navigate the Nucleation and Quenchability of Metastable α-Li₃PS4

α-Li₃PS₄ is a promising solid-state electrolyte with the highest ionic conductivity among its polymorphs. However, its formation presents a thermodynamic paradox: the α-phase is the equilibrium phase at high temperature and transforms to the stable γ-Li3PS4 polymorph when cooled...

P1.095. International Collaborative Study on the Relationship Between ALDH2 Gene Polymorphism and Changes in Salivary Acetaldehyde Concentration by L8020 Lactobacillus

Abstract Topic Esophageal Cancer: Esophageal Carcinogenesis Background Seventy-five percent of the world's esophageal cancer cases occur in Asia. The primary cause is the presence of the flasher (ALDH2 non-inactivating type). The ALDH2 gene polymorphism (rs671 G>A) is believed to...

Analysis of molten particles from the Moto-Ujina Beach, Hiroshima

Abstract Color-sorted spherical molten particles extracted from Moto-Ujina Beach sand were analyzed by inductively coupled plasma–mass spectrometry, thermal ionization mass spectrometry, micro-PIXE analysis to obtain the elemental concentrations, 235 U/ 238 U isotope ratios, and...

Investigating the feasibility of X-ray incident angle determination using radiophotoluminescent glass dosimeter

Abstract Radiophotoluminescent (RPL) glass dosimeters are widely used for personal and environmental radiation monitoring purposes. However, their ability to determine irradiation geometries remains largely unexplored. In this study, we investigated the feasibility of determining...

Type-II Charge-Transfer Photogating in a DDCI-4/MoS2 Heterojunction Phototransistor

Abstract Molecular sensitization of two-dimensional semiconductors offers a route to enhanced photodetection, yet the interfacial charge-transfer mechanisms that govern gain in these hybrid devices are often inferred rather than directly established. Here, we report a multilayer...

A protocol for a prospective single-arm feasibility study of preoperative home-based hydrogen gas inhalation in liver surgery

Introduction: Hydrogen therapy has been reported to exert antioxidative and anti-inflammatory effects and has attracted increasing clinical interest across various medical fields. In cancer treatment, a waiting period often exists between the treatment decision and surgery; howev...

Visualizing diagnosis-associated AMPA receptor-related [11C]K-2 PET SUVR patterns across psychiatric disorders using weakly supervised UMAP

AMPA receptors (AMPARs) mediate fast excitatory neurotransmission and play a central role in synaptic function, with accumulating evidence in psychiatric disorders. Using [ 11 C]K-2 PET to assess AMPAR-related signals in vivo, we examined whether regional standardized uptake valu...
