Biosynthetic Incorporation of Non-native Aryl Acid Building Blocks into Peptide Products Using Engineered Adenylation Domains.

Nonribosomal peptides (NRPs), one of the most widespread secondary metabolites in nature, with therapeutically significant activities, are biosynthesized by modular nonribosomal peptide synthetases (NRPSs). Aryl acids contribute to the structural diversity of NRPs as well as nonproteinogenic amino acids and keto acids. We previously confirmed that a single Asn-to-Gly substitution in the 2,3-dihydroxybenzoic acid-activating adenylation (A) domain EntE involved in enterobactin biosynthesis accepts monosubstituted benzoic acid derivatives with nitro, cyano, bromo, and iodo functionalities at the 2 or 3 positions.

Clinical subtypes of schizophrenia based on the discrepancies between objective performance on social cognition tasks and subjective difficulties in social cognition.

Intervention for social cognition could be key to improving social functioning in patients with schizophrenia. A first step towards its clinical implementation involves interviewing patients about their subjective difficulties with social cognition as they experience them in the real world. The present study focused on the clinical subtypes classified by the discrepancies between the subjective difficulties in social cognition and actual cognitive impairment.

Vaccine Hesitancy and COVID-19 Risk Behaviors Associated with Social Media Use in Japan.

We examined the associations between the use of different types of media and COVID-19 vaccine hesitancy, as well as risk behaviors of COVID-19 infection, in Japan in late 2021. Cross-sectional surveys were conducted using rapid online surveys of residents in Iwate Prefecture from February 5 to 7, 2021, and from October 1 to 3, 2021. Each individual's risk of acquiring SARS-CoV-2 infection was calculated using a quantitative assessment tool (the microCOVID).

Two major bovine milk whey proteins induce distinct responses in IEC-6 intestinal cells.

α-Lactalbumin (α-LA) and β-lactoglobulin (β-LG) are major whey proteins in bovine milk. We studied the effects of these molecules on the intestinal cell response by comparing the native form with the denatured form containing oligomers obtained by treatment with 2,2,2-trifluoroethanol (TFE). We previously reported that proteins in native and TFE-treated forms exhibited cell growth stimulation and cytotoxicity, respectively, in undifferentiated rat crypt IEC-6 and human colon Caco-2 cells.

The evaluation study for social cognition measures in Japan: Psychometric properties, relationships with social function, and recommendations.

Aim: Patients with schizophrenia can have significant subjective difficulties in social cognition, but few undergo testing or treatment for social cognition. The Social Cognition Psychometric Evaluation (SCOPE) study recommends six social cognitive measures; however, the reliability and validity of these measures in different cultural and linguistic areas has not been adequately examined. We examined the psychometric properties of nine social cognitive measures and the relationship to social function, with the aim of determining the level of recommendation for social cognitive measures in clinical practice in Japan.

Varicella outbreak at nursery school under routine immunization in Japan in 2017 and 2018 and vaccine effectiveness.

Background: In Japan, routine administration to one-year-old children of two-dose immunization for varicella was introduced in October 2014. Object The object of this study was to report outbreaks of varicella under routine immunization at a nursery school and in its surrounding area using data of surrounding areas from the (Nursery) School Absenteeism Surveillance System. Then, we measured the effectiveness of routine two-dose immunization for varicella to onset.

Effectiveness of mHealth interventions to promote physical activity and reduce sedentary behaviours on work-related productivity and performance: a systematic review protocol.

Introduction: Technologies such as health and fitness applications (apps) and wearable activity trackers have recently gained popularity and may play a key role in promoting physical activity and reducing sedentary behaviours. Although several systematic reviews have investigated their efficacy in physical activity and sedentary behaviours, few studies have focused on their impact on work-related outcomes among workers. Here, to explore the effects of mHealth interventions designed to encourage physical activity and decrease sedentary behaviours on work-related outcomes, including absenteeism, presenteeism, productivity, work performance and workability among workers, we will conduct a systematic review based on recent articles and an extensive literature search.

Effect of 2% meloxicam injection in Holstein dairy cows on acute clinical mastitis without systemic symptoms.

This study aimed the efficacy of meloxicam (MX) in treating acute clinical mastitis (ACM) without systemic symptoms in Holstein cows by studying improvement in udder pain, changes in prostaglandin E(PGE) and bradykinin (BK) levels in the milk, and milk yield (MY) after healing. Forty-two cows with ACM were randomly assigned to the MX treatment group (T group; n=21) and the control group (C group; n=21). At onset of illness (day 0), the T group received a 0.

[A Case of Resection of T2N0 Colon Cancer with Synchronous Solitary Lung Metastasis].

A 73-year-old man was referred to our hospital for anemia. He underwent a colonoscopy; a 15-mm Ip polyp and a 30- mm type 1 lesion were found in the sigmoid colon. Pathological examination results indicated a well-differentiated adenocarcinoma.

Cardiovascular adverse reactions associated with escitalopram in patients with underlying cardiovascular diseases: a systematic review and meta-analysis.

Background: Despite the anticipated efficacy of escitalopram in treating depression and anxiety in individuals with preexisting cardiovascular conditions, persistent concerns regarding its adverse effects have emerged. In this systematic review, we aimed to evaluate the cardiovascular safety profile of escitalopram compared with that of placebo in patients with underlying cardiovascular disease.

Methods: We used a predefined search strategy in PubMed, Cochrane Central Register of Controlled Trials, Embase, International Clinical Trials Registry Platform, and ClinicalTrials.

Temperature dependent local inhomogeneity and magnetic moments of (LiFe)OHFeSe superconductors.

We have combined the extended X-ray absorption fine structure (EXAFS) and X-ray emission spectroscopy (XES) to investigate the local structure and the local iron magnetic moments of (LiFe)OHFeSe (∼0.2) superconductors. The local structure, studied by Fe K-edge EXAFS measurements, is found to be inhomogeneous that is characterized by different Fe-Se bond lengths.

Determinants of Awareness of Clinical Practice Guidelines among Healthcare Users in Japan.

Clinical practice guidelines (CPGs) are used by both healthcare users and providers, so their recognition is important. The present study's purpose was to clarify the features of healthcare users who are aware of the CPGs. A cross-sectional survey was conducted targeting Internet survey panels ( = 6000).

Endoscopic submucosal dissection using an ultrathin endoscope for superficial pharyngeal cancer: a prospective feasibility study (with video).

Endoscopic submucosal dissection (ESD) of pharyngeal cancers with conventional endoscopes often is difficult, not only because of the narrow working space, but also because endoscope maneuverability in the pharynx is poor due to interference from the endotracheal tube and/or hyoid bone. However, we hypothesized that those problems could possibly be resolved by use of an ultrathin endoscope for ESD of superficial pharyngeal cancer. The aim of this prospective interventional study was to investigate the feasibility of ESD for superficial pharyngeal cancer using an ultrathin endoscope.

Comparison of Analytical Values after Changing to the International Standardized Method for Lactate Dehydrogenase and Alkaline Phosphatase Measurements in Mouse and Rat.

Since April 2020, the method for lactate dehydrogenase (LD) and alkaline phosphatase (ALP) activity measurements in Japan has been switched from the Japan Society of Clinical Chemistry (JSCC) reference method, which is only used in Japan, to the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) reference method. However, in some species, the relationship between the blood values of both enzymes measured by the two methods remains unclear. Hence, values measured by these two methods cannot be used interchangeably.

Effects of a Multimodal Approach Using Buprenorphine with/without Meloxicam on Food Intake, Body Weight, Nest Consolidating Behavior, Burrowing Behavior, and Gastrointestinal Tissues in Postoperative Male Mice.

Distress affects animal welfare and scientific data validity. There is a lack of reports on the effects of multimodal analgesic approaches in mice. In this study, under the hypothesis that a multimodal analgesic protocol using buprenorphine with meloxicam has analgesic effects, we evaluated the effects of a multimodal analgesic protocol using buprenorphine with meloxicam on the well-being of mice during analgesic administration by changing the dosage of meloxicam.

Occupational disparities in COVID-19 vaccine hesitancy in Japan.

Background: We examined occupational disparities in COVID-19 vaccine hesitancy in Japan.

Methods: Cross-sectional online surveys were conducted among of residents living in Iwate Prefecture from July 2 to 4 and from October 1 to 3 in 2021 (total n=17,914). Intention to get vaccinated for COVID-19 was assessed by self-report questions.

A high level of vaccine knowledge increases people's behavioral risks for contracting COVID-19 in Japan.

Background: There has been no study in which the association between levels of vaccine knowledge and preventive behaviors was examined during the COVID-19 pandemic. We examined the transition to risky (transmission) behavior according to level of vaccine knowledge over a seven-month period when vaccines became widely available in Japan.

Methods: A series of cross-sectional surveys were conducted using rapid online surveys of residents in Iwate Prefecture from December 4 to 7 in 2020 (the first survey) and from July 2 to 4 in 2021 (the fourth survey).

Mouse Model of Weak Depression Exhibiting Suppressed cAMP Signaling in the Amygdala, Lower Lipid Catabolism in Liver, and Correlated Gut Microbiota.

To establish a mouse model of weak depression, we raised 6-week-old C57BL/6N mice in single (SH) or group housing (GH) conditions for 2 weeks. The SH group showed less social interaction with stranger mice, learning disability in behavioral tests, and lower plasma corticosterone levels. The cecal microbiota of the SH group showed significant segregation from the GH group in the principal coordinate analysis (PCoA).

Histopathologic effect of in ovo exposure to methotrexate at early embryonic stage on optic tectum of Japanese quail ().

The optic tectum of Japanese quail embryos with in ovo exposure to methotrexate 100 ng/g egg on embryonic day 4 was examined from 3 to 24 hour after treatment. At 9 hour after methotrexate exposure, several apoptotic neuroepithelial cells appeared in the ventricular zone of the optic tectum; these increased in number and were diffusely distributed throughout all layers of the ventricular zone of the optic tectum at 12 hour. At 24 hour, neuroepithelial cells in the ventricular zone of the optic tectum were eliminated and showed sparse cell density.

The effects of compression load to the trunk on lipid metabolism in an inactive phase.

The effects of compression load to a specific body part, e.g. leg, arm, or trunk, evoke many functions and are applied in various fields including clinical medicine, sports, and general health care.

The relationships between environmental parameters in livestock pen and physiological parameters of Holstein dairy cows.

There has been an increase in temperature and the incidence of extreme weather events, such as heat wave, due to global warming, which has promoted the incidence of livestock diseases. Therefore, it is important to examine the effect of changes in environmental parameters on livestock performance. The aim of this study was to examine the relationship between ambient environmental conditions in livestock pen and the physiological parameters of Holstein dairy cows.

Successful esophageal endoscopic submucosal dissection with intraoperative release of stenosis due to previous endoscopic submucosal dissection scarring.

Endoscopic submucosal dissection (ESD) is the standard endoscopic treatment for early esophageal cancer. Esophageal stricture often occurs at the site of ESD for large lesions. When treating a metachronous lesion appearing at the severe stricture, it may be difficult to negotiate a conventional endoscope through the stricture.
