Minimum Scaling Model and Exact Exponents for the Nambu-Goldstone Modes in the Vicsek Model.

We investigate the scaling behavior of Nambu-Goldstone modes in the ordered phase of the Vicsek model, introducing a phenomenological equation of motion incorporating a previously overlooked nonlinear term. This term arises from the interaction between velocity fields and density fluctuations, leading to new scaling behaviors. We derive exact scaling exponents in two dimensions, which reproduce the isotropic scaling behavior reported in a prior numerical simulation.

Characteristics of split-step skills of the world's top athletes in badminton.

Objective: The purpose of this study was to quantitatively measure the split-step skills of the world's top badminton players to clarify the characteristics underlying these skills when moving into the forehand position in the rear court.

Methods: We analyzed the four best ranking players (1st to 4th) in the men's singles competition at the World Badminton Federation (BWF) World Championships 2023, a world tournament whose match videos are available online. Analysis 1 was conducted to determine the location of the players' feet on the court when performing a split-step while moving to the forehand rear court, as well as the width of the stance and the reaction time from that stance to taking the first step.

Nicotine enhances the stemness and tumorigenicity in intestinal stem cells via Hippo-YAP/TAZ and Notch signal pathway.

Cigarette smoking is a well-known risk factor inducing the development and progression of various diseases. Nicotine (NIC) is the major constituent of cigarette smoke. However, knowledge of the mechanism underlying the NIC-regulated stem cell functions is limited.

Aging in a weighted ensemble of excitable and self-oscillatory neurons: The role of pairwise and higher-order interactions.

We investigate the aging transition in networks of excitable and self-oscillatory units as the fraction of inherently excitable units increases. Two network topologies are considered: a scale-free network with weighted pairwise interactions and a two-dimensional simplicial complex with weighted scale-free pairwise and triadic interactions. Without triadic interactions, the aging transition from collective oscillations to oscillation death (inhomogeneous stationary states) can occur either suddenly or through an intermediate state of partial oscillation.

Inactivation Effects of Hypochlorous Acid, Chlorine Dioxide, and Ozone on Airborne SARS-CoV-2 and Influenza A Virus.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and influenza A virus are primarily transmitted through droplets or aerosols from patients. The inactivation effects of existing virus control techniques may vary depending on the environmental factors. Therefore, it is important to establish a suitable evaluation system for assessing virus control techniques against airborne viruses for further real-world implementation.

Modulation of the peak velocities and gains of abduction and adduction saccades according to head position.

Purpose: To assess the effects of modifying head position and of static ocular counter-rolling (OCR) on abduction and adduction in saccadic eye movements using a head-mounted video-oculographic device.

Study Design: A clinical observational study.

Methods: The peak velocities and amplitude gains of visually guided 12° saccades were binocularly measured in 21 healthy volunteers with their heads in the upright vertical (0°) and horizontal (± 90°, bilateral side-lying) postures, and in 6 participants with their head positions bilaterally tilted by 30°.

ARID4B Promotes the Progression of Hepatocellular Carcinoma Through the PI3K/AKT Pathway.

Background: AT-rich interaction domain 4B (ARID4B) is a transcriptional activator that regulates the phosphatidylinositol 3-kinase (PI3K)/AKT pathway in prostate cancer. However, the role of ARID4B in hepatocellular carcinoma (HCC) has remained unclear.

Methods: This study included 162 patients who had undergone primary hepatic resection for HCC between 2008 and 2019.

Regulation of swelling behaviour while preserving bulk modulus in hydrogels surface grafting.

This study presents a novel approach to control "linked property changes" in hydrogels. Specifically, we controlled the swelling behaviour without altering the bulk elastic modulus by grafting polymers selectively into the surface region of the gels, while varying the graft amount.

Nanostructural Analysis of Age-Related Changes Affecting Human Dentin.

Human dentin performs its function throughout life, even though it is not remodeled like bone. Therefore, dentin must have extreme durability against daily repetitive loading. Elucidating its durability requires a comprehensive understanding of its shape, structure, and anisotropy at various levels of its structure.

Sex differences in immunotherapy outcomes and tumor-infiltrating immune cell profiles in patients with advanced renal cell carcinoma.

Sex differences in the outcomes of advanced renal cell carcinoma (RCC) treated with immune checkpoint inhibitors (ICIs) and the profiles of tumor-infiltrating immune cells (TIICs) remain unclear. We retrospectively evaluated data from 563 patients with RCC receiving systemic therapy, including first-line dual ICI combinations (i.e.

Comprehensive epidemiology of melanoma at all sites: insights from Japan's National Cancer Registry, 2016-2017.

Background: Melanoma is a highly malignant cancer responsible for 55 000 deaths worldwide annually. Despite its severity, its epidemiology in Japan remains understudied owing to its rarity among Asians. This study aimed to determine the incidence of melanoma in Japan using data from the National Cancer Registry.

Helicobacter pylori-Related Chronic Gastritis as a Risk Factor for Lower Bone Mineral Density.

We evaluated the role of Helicobacter pylori (H. pylori)-related chronic gastritis in the development of osteoporosis in a population-based study. A total of 1690 subjects in the cohort of the Research on Osteoarthritis/ osteoporosis Against Disability (ROAD) were investigated, and the association between gastritis and osteoporosis was evaluated by the presence of serologically assessed H.

Basic Science and Pathogenesis.

Background: Recent single-cell omics analyses have revealed that microglia change into reactive microglia when Aβ accumulates in the brain and exhibit Aβ phagocytosis. However, reactive microglia are less likely to be induced in TREM2 mutation carriers. This microglia-centred pathological mechanism may be considered one of the pathologies of AD.

Basic Science and Pathogenesis.

Background: In aging societies, neurodegenerative diseases, such as Alzheimer's disease, are receiving attention. These diseases are primary targets for preemptive medicine, emphasizing the importance of early detection and preventive treatment before the onset of severe, treatment-resistant damages. However, there is a lack of comprehensive investigation of lesions and molecular targets in the entire organ, whereas spatial identification of early-stage lesions is potentially overlooked at the single-cell level.

MYO18B promotes lysosomal exocytosis by facilitating focal adhesion maturation.

Many cancer cells exhibit increased amounts of paucimannose glycans, which are truncated N-glycan structures rarely found in mammals. Paucimannosidic proteins are proposedly generated within lysosomes and exposed on the cell surface through a yet uncertain mechanism. In this study, we revealed that paucimannosidic proteins are produced by lysosomal glycosidases and secreted via lysosomal exocytosis.

Isolation of the feline herpesvirus-1 modified live vaccine strain F2 from one of four cats with dendritic ulcers.

Objectives: To investigate the pathogenicity of feline herpesvirus-1 (FHV-1) to the cornea, FHV-1 strains isolated from feline eyes with dendritic ulcers were subjected to genomic analysis to determine whether FHV-1 vaccine strains are involved in the formation of dendritic ulcers.

Methods: All open reading frame (ORF) sequences of the three F2 strains (Virbac, Intervet and Merial) and the FHV-1 clinical isolates from cats registered in GenBank were compared to detect nucleotide variants unique to the F2 strains, with those nucleotides then being used for simple genotyping of the F2 strains. In all isolates from feline eyes with dendritic ulcers, the regions including nucleotide variants of the F2 strain were amplified with PCR and sequenced.

Basic Science and Pathogenesis.

Background: Apolipoprotein E (APOE) ε4 is a significant genetic risk factor for late-onset Alzheimer's Disease and appears to be closely related with brain amyloidosis. Current identification methods for APOE ε4 carriers are mostly based on genotyping which cannot always predict the specific ApoE protein isoform. We present a case study of a sample with a discordant result for genotype compared to the protein isoform (proteotype) and we reflect on possible implications for future applications.

Basic Science and Pathogenesis.

Background: APOE is well recognized to be the most influential susceptibility gene for Alzheimer's disease (AD). For the wild-type allele, e3, it is known that the e4 allele is a risk for AD, while the e2 allele is protective. Recently, genetic analyses with Caucasians have reported the critical associations between APOE rare missense variants (RMVs) and AD, and their importance has been pointed out in terms of disease pathogenesis of AD.

Basic Science and Pathogenesis.

Background: Alzheimer's Disease (AD) manifests early in the olfactory system, yet its precise role in the pathophysiology of AD remains elusive. This study aims to elucidate the progression of olfactory dysfunction in AD by investigating the dysregulation of the adenosine 2A receptor (A2AR) and its potential involvement in the formation of abnormal plaques and tangles. A2AR plays a pivotal role in modulating synaptic transmission and neuroinflammation by regulating both neurons and glial cells.

Basic Science and Pathogenesis.

Background: Recent genome-wide association analysis has identified Bridging Integrator 1 (BIN1) as one of the genetic risk factors for late-onset AD. In AD patients, single nucleotide polymorphisms in BIN1 correlate well with tau pathology, suggesting the involvement of BIN1 in the formation and propagation of tau accumulation pathology, but the molecular mechanism and point of action remain unclear.

Method: To comprehensively clarify the effects of BIN1 on two pathological events, tau aggregation and propagation, we analyzed BIN1 knockout mice.
