The primary endpoint was safety, including treatment-emergent adverse events (TEAEs); secondary endpoints included glycaemic control and body weight.

Superior immunogenicity of high-dose quadrivalent inactivated influenza vaccine versus Standard-Dose vaccine in Japanese Adults ≥ 60 years of age: Results from a phase III, randomized clinical trial.

Background: A high-dose, split-virion inactivated quadrivalent influenza vaccine (IIV4-HD; Sanofi) is being used for the prevention of influenza in multiple countries. This study examined the immunogenicity and safety of the IIV4-HD vaccine administered intramuscularly (IM) compared with a locally licensed standard-dose influenza vaccine (IIV4-SD) administered subcutaneously (SC) in Japan.

Methods: This was a phase III, randomized, modified double-blind, active-controlled, multi-center study in older adults ≥ 60 years of age conducted during the Northern Hemisphere (NH) influenza season of 2020-21 in Japan.

Immunogenicity and Safety of a Quadrivalent Meningococcal Tetanus Toxoid-Conjugate Vaccine (MenACYW-TT) in Meningococcal Vaccine-Naïve Participants across a Broad Age Range (2-55 Years) in Japan: a Phase III Randomized Study.

MenACYW-TT is a quadrivalent meningococcal tetanus toxoid-conjugate vaccine designed to prevent invasive meningococcal disease. The primary objective of this study was to demonstrate non-inferiority of the vaccine seroresponse to a single dose of MenACYW-TT compared with MCV4-DT, a licensed meningococcal quadrivalent diphtheria-conjugate vaccine. This Phase III double-blind, multicenter trial was conducted in meningococcal vaccine-naïve individuals aged 2-55 years in Japan (NCT04368429; jRCT2080225192).

SCO-267, a GPR40 Full Agonist, Stimulates Islet and Gut Hormone Secretion and Improves Glycemic Control in Humans.

SCO-267 is a full agonist of the free fatty acid receptor 1 (GPR40), which regulates the secretion of islet and gut hormones. In this phase 1 study, we aimed to evaluate the clinical profile of single and multiple once-daily oral administration of SCO-267 in healthy adults and patients with diabetes. Plasma SCO-267 concentration was seen to increase in a dose-dependent manner after administration, and its plasma exposure was maintained for 24 h.

Immunogenicity and Safety of a Two-Dose Series of a Meningococcal (Groups A, C, W, and Y) Polysaccharide Diphtheria Toxoid Conjugate Vaccine (Men-ACWY-D) in Healthy Japanese Adults.

The quadrivalent meningococcal polysaccharide diphtheria toxoid conjugate vaccine (Men-ACWY-D) has been licensed for use in Japan since 2014. An earlier registration study demonstrated the immunogenicity of a single dose in Japanese adults, wherein the immunogenicity against serogroup C was the lowest. The determination of the potential to increase the serogroup C response with a second dose was, therefore, of interest.

Immunogenicity and safety of high-dose quadrivalent influenza vaccine in Japanese adults ≥65 years of age: a randomized controlled clinical trial.

A trivalent high-dose inactivated influenza vaccine has been licensed in healthy adults ≥65 years of age and provides better protection against influenza infection and related complications than trivalent standard-dose vaccine. This phase I/II clinical trial (NCT03233217), conducted at two sites in Japan, examined the safety and immunogenicity of a quadrivalent formulation of the high-dose inactivated influenza vaccine (IIV4-HD). Healthy adults ≥65 years of age were randomized to receive IIV4-HD by intramuscular injection (n = 60), IIV4-HD by subcutaneous injection (n = 60), or a quadrivalent standard-dose inactivated influenza vaccine (IIV4-SD) by subcutaneous injection (n = 55).

Safety and immunogenicity of Clostridium difficile toxoid vaccine in Japanese adults.

This was a randomized, placebo-controlled, Phase I/II study conducted in a Japanese cohort to assess the safety and immunogenicity of Clostridium difficile vaccine (the same formulation as that used in the ongoing global Phase III study). Healthy Japanese adults aged 40-75 years were randomized to receive either C. difficile vaccine (N = 67) or placebo (N = 34) by intramuscular injection on Days 0, 7, and 30.

Background: A Phase 2, dose-ranging study of bococizumab, a monoclonal anti-proprotein convertase subtilisin/kexin type 9 antibody, was conducted in Japanese subjects to assess its efficacy, safety, and tolerability in this population.

Methods and results: Two different hypercholesterolemic study populations were enrolled concurrently: Japanese subjects with uncontrolled low-density lipoprotein cholesterol (LDL-C) despite atorvastatin treatment (LDL-C ≥100 mg/dL; n=121), and Japanese subjects naive to lipid-lowering agents and with LDL-C ≥130 mg/dL (n=97). Subjects within each study population were randomized to bococizumab 50, 100, or 150 mg, or placebo, q14D for 16 weeks; an open-label ezetimibe 10 mg daily arm was also included for the atorvastatin-treated population.

Efficacy and Safety of Alirocumab in Japanese Subjects (Phase 1 and 2 Studies).

We assessed the safety and tolerability of ascending single doses of alirocumab in healthy Japanese subjects and evaluated the effect of alirocumab at 3 doses (50, 75, 150 mg) on low-density lipoprotein cholesterol (LDL-C) reduction in patients with primary hypercholesterolemia on atorvastatin. A randomized, single ascending-dose study of alirocumab (100, 150, 250, or 300 mg) or placebo (3:1 ratio), administered subcutaneously, was conducted in 32 healthy Japanese men. The phase 2, randomized, double-blind, placebo-controlled, parallel-group study was performed in patients with primary hypercholesterolemia (defined as calculated LDL-C ≥100 mg/dl [2.

Nonorthogonal molecular orbital method: single-determinant theory.

Using the variational principle, we have derived a variant of the Adams-Gilbert equation for nonorthogonal orbitals of a single-determinant wave function, which we name the modified Adams-Gilbert equation. If we divide the molecular system into several subsystems, such as bonds, lone pairs, and residues, we can solve the equations for the subsystems one by one. Thus, this procedure has linear scaling.

A histone H1 variant is required for erythrocyte maturation in medaka.

Three histone H1 variants were identified in medaka fish and their sequence characteristics were analyzed. This paper reports one of these variants, termed H1-2, because of its possible implication in erythrocyte maturation. The amino acid sequence of H1-2 was phylogenetically similar to that of other replication-dependent histones.

Expression of estrogen receptor alpha and beta in reactive astrocytes at the male rat hippocampus after status epilepticus.

Estrogen is neuroprotective against status epilepticus (SE)-induced hippocampal damage in female animals. In male animals, estrogen is converted from testosterone via aromatization the activity of which is upregulated by brain damage. However, it is controversial whether estrogen is neuroprotective or neuroinvasive against male hippocampal damage after SE.

[A child with non-herpetic acute limbic encephalitis affecting the claustrum and hippocampus].

We experienced an 8-year-old-boy with non-herpetic acute limbic encephalitis (NHALE), who developed headache, convulsion, consciousness disturbance, and ataxia following cold like symptoms. Disturbance of short term memory and a change of character were recognized. Myoclonic seizures and generalized tonic clonic convulsions developed, that responded to antiepileptic agents.

Kainic acid dose affects delayed cell death mechanism after status epilepticus.

Kainic acid (KA)-induced status epilepticus (SE) produces hippocampal neuronal death, which varies from necrosis to apoptosis or programmed cell death (PCD). We examined whether the type of neuronal death was dependent on KA dose. Adult rats were induced SE by intraperitoneal injection of KA at 9 mg/kg (K9) or 12 mg/kg (K12).

NC-AFM observation of atomic scale structure of rutile-type TiO2(110) surface prepared by wet chemical process.

We succeeded in observing the atomic scale structure of a rutile-type TiO2(110) single-crystal surface prepared by the wet chemical method of chemical etching in an acid solution and surface annealing in air. Ultrahigh vacuum noncontact atomic force microscopy (UHV-NC-AFM) was used for observing the atomic scale structures of the surface. The UHV-NC-AFM measurements at 450 K, which is above a desorption temperature of molecularly adsorbed water on the TiO2(110) surface, enabled us to observe the atomic scale structure of the TiO2(110) surface prepared by the wet chemical method.

Chain structures of surface hydroxyl groups formed via line oxygen vacancies on TiO2(110) surfaces studied using noncontact atomic force microscopy.

Structures of surface hydroxyl groups arranged on a reduced TiO2(110) surface that had line oxygen vacancies were studied using noncontact atomic force microscopy (NC-AFM). NC-AFM results revealed that by increasing the density of oxygen vacancies on the TiO2(110) surface, line oxygen vacancies were formed by removal of oxygen atoms in a bridge oxygen row on the TiO2(110) surface. After the TiO2(110) surface with the line oxygen vacancies was exposed to water, the surface showed hydroxyl chain structures that were composed of hydroxyl groups linearly arranged in a form of two rows on the line oxygen vacancies and on a neighboring bridge oxygen row.

Common carotid intima-media thickness is predictive of all-cause and cardiovascular mortality in elderly community-dwelling people: Longitudinal Investigation for the Longevity and Aging in Hokkaido County (LILAC) study.

Several cohort studies have examined the association of carotid intima-media thickness (IMT) with the risk of stroke or myocardial infarction in apparently healthy persons. We investigated the predictive value of IMT of cardiovascular mortality in elderly community-dwelling people, beyond the prediction provided by age and MMSE, assessed by means of a multivariate Cox model. Carotid IMT and plaque were evaluated bilaterally with ultrasonography in 298 people older than 75 years (120 men and 178 women, average age: 79.
