Therapeutic Effectiveness of a Novel Cranial Remolding Helmet (baby band2) for Positional Plagiocephaly: A Multicenter Clinical Observational Study.

This multicenter study evaluated the efficacy and safety of a novel cranial remolding helmet (baby band2), which is completely custom-made based on the shape of an infant's cranium. The study included 224 full-term infants from moderate to very severe positional plagiocephaly in Japan. Cranial geometry was assessed before and after helmet therapy using a three-dimensional scanner, and changes in the cranial vault asymmetry index (CVAI) were analyzed.

Magicity versus Superfluidity around ^{28}O viewed from the Study of ^{30}F.

The neutron-rich unbound fluorine isotope ^{30}F_{21} has been observed for the first time by measuring its neutron decay at the SAMURAI spectrometer (RIBF, RIKEN) in the quasifree proton knockout reaction of ^{31}Ne nuclei at 235  MeV/nucleon. The mass and thus one-neutron-separation energy of ^{30}F has been determined to be S_{n}=-472±58(stat)±33(sys)  keV from the measurement of its invariant-mass spectrum. The absence of a sharp drop in S_{n}(^{30}F) shows that the "magic" N=20 shell gap is not restored close to ^{28}O, which is in agreement with our shell-model calculations that predict a near degeneracy between the neutron d and fp orbitals, with the 1p_{3/2} and 1p_{1/2} orbitals becoming more bound than the 0f_{7/2} one.

Precise Spectroscopy of the 3n and 3p Systems via the ^{3}H(t, ^{3}He)3n and ^{3}He(^{3}He, t)3p Reactions at Intermediate Energies.

To search for low-energy resonant structures in isospin T=3/2 three-body systems, we have performed the experiments ^{3}H(t,^{3}He)3n and ^{3}He(^{3}He,t)3p at intermediate energies. For the 3n experiment, we have newly developed a thick Ti-^{3}H target that has the largest tritium thickness among targets of this type ever made. The 3n experiment for the first time covered the momentum-transfer region as low as 15  MeV/c, which provides ideal conditions for producing fragile systems.

Mass, Spectroscopy, and Two-Neutron Decay of ^{16}Be.

The structure and decay of the most neutron-rich beryllium isotope, ^{16}Be, has been investigated following proton knockout from a high-energy ^{17}B beam. Two relatively narrow resonances were observed for the first time, with energies of 0.84(3) and 2.

Helical peptides with disordered regions for measles viruses provide new generalized insights into fusion inhibitors.

Despite effective vaccines, measles virus (MeV) outbreaks occur sporadically. Therefore, developing anti-MeV agents remains important for suppressing MeV infections. We previously designed peptide-based MeV fusion inhibitors, M1 and M2, that target MeV class I fusion protein (F protein).

Helix-based screening with structure prediction using artificial intelligence has potential for the rapid development of peptide inhibitors targeting class I viral fusion.

The rapid development of drugs against emerging and re-emerging viruses is required to prevent future pandemics. However, inhibitors usually take a long time to optimize. Here, to improve the optimization step, we used two heptad repeats (HR) in the spike protein (S protein) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as a model and established a screening system for peptide-based inhibitors containing an α-helix region (SPICA).

Validation of the ^{10}Be Ground-State Molecular Structure Using ^{10}Be(p,pα)^{6}He Triple Differential Reaction Cross-Section Measurements.

The cluster structure of the neutron-rich isotope ^{10}Be has been probed via the (p,pα) reaction at 150  MeV/nucleon in inverse kinematics and in quasifree conditions. The populated states of ^{6}He residues were investigated through missing mass spectroscopy. The triple differential cross section for the ground-state transition was extracted for quasifree angle pairs (θ_{p},θ_{α}) and compared to distorted-wave impulse approximation reaction calculations performed in a microscopic framework using successively the Tohsaki-Horiuchi-Schuck-Röpke product wave function and the wave function deduced from antisymmetrized molecular dynamics calculations.

First observation of O.

Subjecting a physical system to extreme conditions is one of the means often used to obtain a better understanding and deeper insight into its organization and structure. In the case of the atomic nucleus, one such approach is to investigate isotopes that have very different neutron-to-proton (N/Z) ratios than in stable nuclei. Light, neutron-rich isotopes exhibit the most asymmetric N/Z ratios and those lying beyond the limits of binding, which undergo spontaneous neutron emission and exist only as very short-lived resonances (about 10 s), provide the most stringent tests of modern nuclear-structure theories.

Alcoholic ketoacidosis evaluated with a point-of-care capillary beta-hydroxybutyrate measurement device.

Background: The diagnosis of alcoholic ketoacidosis (AKA) has traditionally been made based only on clinical history and the presence of severe metabolic acidosis with a high anion gap (AG); however, the concentration of beta-hydroxybutyrate (BOHB), a pivotal ketone body in AKA, is not evaluated in most cases. The aim of this study was to clarify the clinical spectrum of AKA in terms of the severity of ketoacidosis by using a point-of-care capillary BOHB measurement device.

Methods: This retrospective case series was conducted at a Japanese private teaching hospital.

Multiple Mechanisms in Proton-Induced Nucleon Removal at ∼100 MeV/Nucleon.

We report on the first proton-induced single proton- and neutron-removal reactions from the neutron-deficient ^{14}O nucleus with large Fermi-surface asymmetry S_{n}-S_{p}=18.6  MeV at ∼100  MeV/nucleon, a widely used energy regime for rare-isotope studies. The measured inclusive cross sections and parallel momentum distributions of the ^{13}N and ^{13}O residues are compared to the state-of-the-art reaction models, with nuclear structure inputs from many-body shell-model calculations.

Impact of nutritional guidance on various clinical parameters in patients with moderate obesity: A retrospective study.

Context: This study aims to investigate whether there is adequate provision of nutritional guidance through interventions by registered dietitians, especially for patients with moderate obesity. This is particularly important as such interventions may prove to be more effective for Japanese patients.

Methods: In Japan, since there is a system of nutritional guidance with a registered dietitian for patients with a BMI over 30 kg/m, we recruited 636 patients with obesity who had a BMI over 30 kg/m admitted to the Kawasaki Medical School General Medical Center between April 2018 and March 2020 through a review of their medical records.

Pneumococcal meningitis in a patient with severe COVID-19 on dexamethasone and tocilizumab: A case report.

Although various therapeutic agents have been tried for coronavirus disease-2019 (COVID-19) and evidence has accumulated, the risk of secondary infection is increased by underlying disease and immunosuppressive drugs. We report a case of pneumococcal meningitis in a patient with severe COVID-19 who was receiving dexamethasone and tocilizumab. The patient's symptoms improved with appropriate diagnosis and antimicrobial therapy, and she fortunately returned to society without any neurological sequelae of meningitis.

Establishing an accurate and sensitive in vitro drug screening system for human adenovirus infection with human corneal cells.

Epidemic keratoconjunctivitis (EKC) is a hazardous and highly contagious disease, with the potential to cause epidemic outbreaks in hospitals and other community settings. There are currently no approved drugs for human adenovirus (HAdV), the causative agent of EKC. To establish a novel drug screening system for ocular HAdV infections, we employed CRL11516, a non-cancerous but immortalized human corneal epithelial cell line.

Extended p_{3/2} Neutron Orbital and the N=32 Shell Closure in ^{52}Ca.

The one-neutron knockout from ^{52}Ca in inverse kinematics onto a proton target was performed at ∼230  MeV/nucleon combined with prompt γ spectroscopy. Exclusive quasifree scattering cross sections to bound states in ^{51}Ca and the momentum distributions corresponding to the removal of 1f_{7/2} and 2p_{3/2} neutrons were measured. The cross sections, interpreted within the distorted-wave impulse approximation reaction framework, are consistent with a shell closure at the neutron number N=32, found as strong as at N=28 and N=34 in Ca isotopes from the same observables.

Evaluating Cranial Growth in Japanese Infants Using a Three-dimensional Scanner: Relationship between Growth-related Parameters and Deformational Plagiocephaly.

In this study, we aimed to evaluate the longitudinal changes in the cranial shape of healthy Japanese infants using a three-dimensional scanner and construct a normal values database for the growth process. Preterm infants (gestational age < 37 weeks), infants with neonatal asphyxia (5-minute Apgar score of <7), and patients who started helmet therapy for deformational plagiocephaly were excluded from this study. The first scan was performed at approximately 1 month of age, followed by two scans conducted at 3 and 6 months of age.

Serine hydroxymethyltransferase as a potential target of antibacterial agents acting synergistically with one-carbon metabolism-related inhibitors.

Serine hydroxymethyltransferase (SHMT) produces 5,10-methylenetetrahydrofolate (CH-THF) from tetrahydrofolate with serine to glycine conversion. SHMT is a potential drug target in parasites, viruses and cancer. (+)-SHIN-1 was developed as a human SHMT inhibitor for cancer therapy.

Observation of a correlated free four-neutron system.

A long-standing question in nuclear physics is whether chargeless nuclear systems can exist. To our knowledge, only neutron stars represent near-pure neutron systems, where neutrons are squeezed together by the gravitational force to very high densities. The experimental search for isolated multi-neutron systems has been an ongoing quest for several decades, with a particular focus on the four-neutron system called the tetraneutron, resulting in only a few indications of its existence so far, leaving the tetraneutron an elusive nuclear system for six decades.

A phytoplasma effector acts as a ubiquitin-like mediator between floral MADS-box proteins and proteasome shuttle proteins.

Plant pathogenic bacteria have developed effectors to manipulate host cell functions to facilitate infection. A certain number of effectors use the conserved ubiquitin-proteasome system in eukaryotic to proteolyze targets. The proteasome utilization mechanism is mainly mediated by ubiquitin interaction with target proteins destined for degradation.

Natural-Course Evaluation of Infants with Positional Severe Plagiocephaly Using a Three-Dimensional Scanner in Japan: Comparison with Those Who Received Cranial Helmet Therapy.

This study aimed to clarify the natural course of positional plagiocephaly using a three-dimensional (3D) scanner and investigate the effectiveness of cranial helmet therapy (CHT). One hundred infants with severe plagiocephaly who visited our institutions between April 2020 and March 2021 were included. Cranial shape was measured using an Artec Eva 3D scanner.

Pairing Forces Govern Population of Doubly Magic ^{54}Ca from Direct Reactions.

Direct proton-knockout reactions of ^{55}Sc at ∼220  MeV/nucleon were studied at the RIKEN Radioactive Isotope Beam Factory. Populated states of ^{54}Ca were investigated through γ-ray and invariant-mass spectroscopy. Level energies were calculated from the nuclear shell model employing a phenomenological internucleon interaction.

An improved primer design for the loop-mediated isothermal amplification (LAMP) method to detect oxacillinase (OXA)-48 β-lactamase genes in Gram-negative bacteria for clinical applications.

Introduction: Recently, increased frequencies of carbapenemase-producing Enterobacteriaceae have been reported worldwide. Among multiple genetic subtypes, oxacillinase (OXA)-48 β-lactamase-producing strains have been associated with inbound infection because they have been detected predominantly in patients who traveled outside of Japan. However, a recent case report of OXA-48 β-lactamase-producing Enterobacteriaceae suggested the latent spread of domestic infections.

The Epithelial-to-Mesenchymal Transition-Like Process Induced by TGF-β1 Enhances Rubella Virus Binding and Infection in A549 Cells via the Smad Pathway.

Virus-host cell interactions in rubella virus (RuV) are of great interest in current research in the field, as their mechanism is not yet well understood. By hypothesizing that the epithelial-to-mesenchymal transition (EMT) may play a role in RuV infection, this study aimed to investigate the influence of TGF-β1-induced EMT of human lung epithelial A549 cells on the infectivity of RuV. A549 cells were cultured and treated with TGF-β1 for 1 to 2 days prior to virus infection (with a clinical strain).

Plutonium dioxide particle imaging using a high-resolution alpha imager for radiation protection.

The internal exposure of workers who inhale plutonium dioxide particles in nuclear facilities is a crucial matter for human protection from radiation. To determine the activity median aerodynamic diameter values at the working sites of nuclear facilities in real time, we developed a high-resolution alpha imager using a ZnS(Ag) scintillator sheet, an optical microscope, and an electron-multiplying charge-coupled device camera. Then, we designed and applied a setup to measure a plutonium dioxide particle and identify the locations of the individual alpha particles in real time.
