REM disruption and REM vagal activity predict extinction recall in trauma-exposed individuals.

Background: Accumulating evidence suggests that rapid eye movement sleep (REM) supports the consolidation of extinction memory. REM is disrupted in posttraumatic stress disorder (PTSD), and REM abnormalities after traumatic events increase the risk of developing PTSD. Therefore, it was hypothesized that abnormal REM in trauma-exposed individuals may pave the way for PTSD by interfering with the processing of extinction memory.

Evaluation of stopping power ratio of artificial breast implants for carbon-ion radiotherapy.

The number of patients requiring breast reconstruction with artificial implants has been increasing, and so is the use of carbon-ion radiotherapy (CIRT). Consequently, a growing number of patients with artificial breast implants are expected to undergo CIRT. Because artificial breasts are composed of a silicone polymer gel with a silicon-oxygen backbone, which differs significantly from human tissues, the stopping power ratio for carbon beams cannot be accurately converted from CT values using standard CT-to-stopping power ratio tables (CT-SP tables).

Localization of silica nanoparticles to lysosome causes lysosomal dysfunction in JEG-3 cells.

Nanoparticles have useful functions due to the characteristics conferred on them by an increase in their specific surface area, and they have already been put into practical use in products in various industrial fields. Although exposure to nanoparticles in daily life is unavoidable for pregnant women, studies that evaluate the toxicity of nanoparticles in pregnant women are lacking. To redress this, we have focused on the placenta and have previously revealed that nanoparticles can show placental toxicity.

Association between Gray and White Matter Lesions and Its Involvement in Clinical Symptoms of Alzheimer's-Type Dementia.

Background: Not only gray matter lesions (GMLs) but also white matter lesions (WMLs) can play important roles in the pathology of Alzheimer's disease (AD). The progression of cognitive impairment (CI) and behavioral and psychological symptoms of dementia (BPSD) might be caused by a concerted effect of both GML and WML.

Objective: This study aimed to investigate the association between GML and WML and how they are involved in the symptoms of CI and BPSD in dementia patients by means of imaging technology.

Impact of hs-CRP concentration on brain structure alterations and cognitive trajectory in Alzheimer's disease.

Introduction: Present study was to investigate hs-CRP concentration, brain structural alterations, and cognitive function in the context of AD [Subjective cognitive decline (SCD), mild cognitive impairment (MCI), and AD].

Methods: We retrospectively included 313 patients (Mean age = 76.40 years, 59 SCD, 101 MCI, 153 AD) in a cross-sectional analysis and 91 patients (Mean age = 75.

Combination Therapy with Betamethasone and Josamycin Demonstrates Superior Therapeutic Efficacy in an NC/Nga Mouse Model of Atopic Dermatitis.

We have previously demonstrated the excellent bactericidal activity of josamycin against Staphylococcus aureus isolated from patients with atopic dermatitis (AD), with therapeutic efficacy equal to that of betamethasone. The present study was designed to evaluate the effectiveness of combination therapy with betamethasone and josamycin for AD. Betametasone (0.

Vesicular Integral-Membrane Protein 36 Is Involved in the Selective Secretion of Fucosylated Proteins into Bile Duct-like Structures in HepG2 Cells.

Fucosylated proteins are widely used as biomarkers of cancer and inflammation. Fucosylated alpha-fetoprotein (AFP-L3) is a specific biomarker for hepatocellular carcinoma. We previously showed that increases in serum AFP-L3 levels depend on increased expression of fucosylation-regulatory genes and abnormal transport of fucosylated proteins in cancer cells.

Efficacy of a mixture of Ginkgo biloba, sesame, and turmeric on cognitive function in healthy adults: Study protocol for a randomized, double-blind, placebo-controlled trial.

Background And Purpose: Ginkgo biloba extract (GBE) reportedly ameliorates cognitive function in patients with chronic cerebrovascular insufficiency. However, its efficacy in healthy adults is ambiguous. It was reported that concentrations of terpene lactones, active components of GBE that are present in very low concentrations in the brain, were significantly increased following administration of a mixture of GBE, sesame seed, and turmeric (GBE/MST) in mice.

Impact of atrial fibrillation on the cognitive decline in Alzheimer's disease.

Background: Atrial fibrillation (AF) is a strong risk factor for Alzheimer's disease (AD) independent of ischemic stroke. However, the clinicopathological impact of AF on the severity of AD has not been well elucidated. We aimed to investigate the clinical differences between dementia patients with AF and those without AF by means of imaging data.

Unique insertion/deletion polymorphisms within histidine-rich region of histidine-rich glycoprotein in Thoroughbred horses.

Histidine-rich glycoprotein (HRG) is abundant plasma protein with various effects on angiogenesis, coagulation, and immune responses. Previously, we identified the base and amino acid sequences of equine HRG (eHRG) and revealed that eHRG regulates neutrophil functions. In this study, we first conducted a large-scale gene analysis with DNA samples extracted from 1700 Thoroughbred horses and identified unique insertion/deletion polymorphisms in the histidine-rich region (HRR) of eHRG.

Oral Administration of Meloxicam and Flunixin Meglumine Have Similar Analgesic Effects After Lipopolysaccharide-Induced Inflammatory Response in Thoroughbred Horses.

Flunixin meglumine (FM), a nonselective cyclooxygenase (COX) inhibitor, is most frequently selected for the treatment of equine systemic inflammatory response syndrome (SIRS)/endotoxemia. However, FM has considerable adverse effects on gastrointestinal function. The aims of this study were to compare the effect of meloxicam (MX), a COX-2 selective inhibitor commonly used in equine clinical practice, with FM, and to investigate the potential for clinical application in horses with SIRS/endotoxemia.

Impact of constipation on progression of Alzheimer's disease: A retrospective study.

Background And Purpose: In terms of the gut-brain axis, constipation has been considered to be an important factor of neurodegenerative diseases, although the exact mechanism is still controversial. Herein, we aimed to investigate the contribution of constipation to the progression of dementia in a retrospective study.

Methods: Patients of Alzheimer's disease(AD) and amnestic mild cognitive impairment were consecutively screened between January 2015 and December 2020, and those of whom brain MRI and neuropsychological tests were performed twice were enrolled in this study.

Perceived social isolation is correlated with brain structure and cognitive trajectory in Alzheimer's disease.

Both objective and perceived social isolations were associated with future cognitive decline and increase risk of Alzheimer's disease (AD). However, the impacts of perceived social isolation depending on different clinical stages of AD have not been elucidated. The aim of this study was to investigate the influence of perceived social isolation or loneliness on brain structure and future cognitive trajectories in patients who are living with or are at risk for AD.

Change in short distance swimming performance following inspiratory muscle fatigue.

Background: Inspiratory muscle fatigue (IMF) may impair performance in a subsequent exercise. A few studies have reported that IMF decreased swimming performance in submaximal intensity or severe intensity domain. However, the impact of IMF on high-intensity short-duration swimming is not clear.

Mortality, clinical findings, predisposing factors and treatment of colitis in Japanese thoroughbred racehorses.

Background: Although -associated diseases (CDAD) is considered to be associated with colitis in horses, few studies have been performed with a focus on the characteristics of CDAD in thoroughbred racehorses.

Methods: Between 2010 and 2018, a test for was performed using faecal samples from 137 thoroughbred racehorses with colitis presenting with diarrhoea and fever. The mortality rate, clinical findings, predisposing factors and the selected treatments were investigated in a retrospective manner.

Prevalence of Smoking Among 4 Licensed Types of Nursing Personnel in Japan: An Epidemiological Study.

There is a high prevalence of smoking among nursing personnel, despite the fact that nursing is a health care profession. In Japan there are 4 types of licensed nursing professionals. However, the prevalence of smoking among different types of licensed personnel has not been clarified.

Perceptions of traditional and modern types of depression: A cross-cultural vignette survey comparing Japanese and American undergraduate students.

Aim: Depression is a heterogeneous disorder that has various subtypes. In Japan, however, a prevailing misunderstanding is that the term utsu-byo (clinical depression) indicates only the melancholic type. Consequently, a subtype called 'modern-type depression' (MTD), which has contrasting features to those of melancholic or traditional-type depression (TTD), is severely stigmatized in Japan these days.

Evaluating continuous blood coagulopathy in assessing the severity of acute colitis in Thoroughbred racehorses.

Although severe blood coagulopathy in horses with acute colitis causes multiple organ failure, which may be fatal, few studies have focused on the correlation between the fluctuations of coagulation parameters and severity of colitis. In this study, we evaluated the fluctuations of coagulation parameters in 14 Thoroughbred racehorses with acute colitis for 5 days from the day of hospitalization and compared them between 5 survivors and 9 non-survivors. Noteworthy features in the non-survivors were that antithrombin activity and fibrin degradation products continuously decreased and increased, respectively, for 4 days or more and that thrombin-antithrombin complexes increased in the last 2 days before death.

[Development of the Interpersonal Sensitivity/Privileged Self Scale: The measurement of a psychological characteristic related to “Modern-type Depression”].

We developed the Interpersonal Sensitivity/Privileged Self Scale (IPS) to measure personality traits related to “modern-type depression,” and assessed its validity and reliability through three surveys completed by 804 undergraduates. Factors for validity were examined by confirmatory factor analysis. As predicted, the scale comprised two superordinate factors: interpersonal sensitivity (IS) and privileged self (PS).

A comparison of perceptions of 'modern-type' and melancholic depression in Japan.

Background: In Japan, psychiatrists have noted two different types of depression, traditional/melancholic depression and 'modern-type' depression (MTD). Although both the modern and the traditional types of depression overlap in regard to symptoms, these are two distinct syndromes, which can lead to confusion for Japanese people.

Aims: This study aims to examine impressions of two types of depression using vignettes and clarify the differences in perceptions of the two types.

Aneurysm of the cranial mesenteric artery as a site of carriage of Salmonella enterica subsp. enterica serovar Abortusequi in the horse.

Salmonella enterica subsp. enterica serovar Abortusequi is a pathogen restricted to horses. Our investigation targeted 4 draft horses (9-10 months old) kept on a Japanese farm that had suffered an outbreak of S.

Identification of immunodiagnostic antigens for cerebrospinal filariasis in horses by western blot analysis.

In the present study, the serum and cerebrospinal fluid of horses diagnosed with Setaria digitata cerebrospinal filariasis were analyzed by western blot. The results revealed S. digitata protein bands measuring 65, 34, 22, and 18 kDa in molecular weight.

Ultrasound for differentiation between perforated and nonperforated appendicitis in pediatric patients.

Objective: Acute appendicitis is the most common condition requiring emergency surgery in children. Differentiation of perforated from nonperforated appendicitis is important because perforated appendicitis may initially be managed conservatively whereas nonperforated appendicitis requires immediate surgical intervention. CT has been proved effective in identifying appendiceal perforation.
