In-situ analysis of heterogeneous catalysts under reaction condition is indispensable to understand reaction mechanisms and nature of active sites. Ambient-pressure X-ray photoelectron spectroscopy (AP-XPS) is one of the powerful methods to investigate chemical states of catalysts and reaction intermediates adsorbed on the surface. In this review, reaction of carbon dioxide on Cu(997) and Zn-deposited Cu(997) surfaces are discussed as an example of surface chemistry of weakly adsorbed molecules, together with a brief overview of recent progress in AP-XPS methods.

Background We aimed to estimate the prevalence of depressive symptoms as well as suicide-related ideation among Japanese university students during the stay-home order necessitated by the coronavirus disease 2019 pandemic in Japan, and offer evidence in support of future intervention to depression and suicide prevention strategies among college and university students. Methods The data for this cross-sectional study were derived from the Student Mental Health Survey conducted from May 20 to June 16, 2020 at a national university in Akita prefecture. Among the 5111 students recruited, 2712 participated in this study (response rate, 53%; mean age ± standard deviation, 20.5 ±3.5 years; men, 53.8%). Depressive symptoms were identified by using the Patient Health Questionnaire-9 (PHQ-9). Results The prevalence of moderate depressive symptoms based on a PHQ-9 score ≥10 and suicide-related ideation based on question 9 of PHQ-9 ≥1, which encompasses thoughts of both suicide and self-harm, was 11.7% and 6.7%, respectively. Multivariable logistic regression analyses showed that risk factors for depression included being a woman, smoking, alcohol consumption, and social network communication using either video or voice. For suicide-related ideation, alcohol consumption was the only risk factor. Exercise and having someone to consult about worries were associated with decreased risk of both depressive symptoms and suicide-related ideation. Conclusions Negative lifestyles of smoking and drinking, and being a woman, may be important risk factors for depressive symptoms, whereas exercise and having someone to consult about worries may be protective factors.

Scurvy is a rare disease caused by a vitamin C deficiency. Vitamin C is a water-soluble vitamin found in vegetables and fruits, but it is lost after boiling. A 59-year-old man presented with gingival pain after having a tooth extracted five years previously. Following the procedure, his diet comprised boiled vegetables to prevent pain. He then experienced bilateral lower leg pain, and computed tomography revealed intramuscular bleeding. His serum vitamin C level was below the detectable limit. His symptoms immediately improved with vitamin C administration. This case emphasized that consuming only boiled vegetables can lead to the onset of scurvy.

業務トリップは、通勤トリップと異なり広い時間帯で発生することや、複数の目的地を持つトリップチェインを形成する傾向が強い等の特徴を持つ。本研究では、トリップチェイン前後の業務活動も含めたトリップチェイン全体の費用最小化行動を仮定した、業務トリイプの経路・出発時刻選択モデルを構築した。出発時刻選択については最適な出発時刻で総費用が極小値をとるとの条件を用い、連続時間軸上での時刻選択行動をモデル化した。路側配布によるアンケート調査で得られた実際のトリップチェインデータ、および時間帯別所要時間データに基づき未知パラメータを推定した。さらに、出発時刻や経路、立ち回り順序の変更や所要時間の変化に伴なう費用の変化を産出し、モデルの挙動を確認した。Unlike commute trips, business trips are generated throughout business hours, and several destinations tend to be visited in a trip chain. In this study, a route and departure time choice model for a business trip chain is developed based on the hypothesis that the trip chain is made so as to minimize the total cost, including costs associated with other business activities before and after the trip chain, as well as costs associated with travel time, toll fees, and the probability of being late. The empirical analysis is carried out using a data set obtained from a survey of business trip drivers. The properties of the estimated model are examined on a sample case

Fibroblast growth factor-2 (FGF-2) regulates several vascular endothelial cell functions, including proliferation. It has been suggested that the regulation may be modulated by reactive sulfur species (RSS), which are hydrogen sulfide and biomolecules containing persulfide/polysulfide groups. Since RSS promote vascular endothelial cell proliferation, we hypothesized that FGF-2 regulates the levels of RSS-producing enzymes in the cells. Bovine aortic endothelial cells were cultured and treated with FGF-2, and intracellular RSS levels were determined. The expression of RSS-producing enzymes, cystathionine γ-lyase (CSE), cystathionine β-synthase, 3-mercaptopyruvate sulfurtransferase, and cysteinyl-tRNA synthetase 2, was evaluated, and the intracellular signaling pathway that mediates FGF-2 regulation of RSS accumulation was investigated. We revealed that FGF-2 upregulates the expression of RSS by selectively inducing CSE via the ERK1/2 signaling pathway in vascular endothelial cells. The effect of FGF-2 on the function of vascular endothelial cells may be modulated by intracellular RSS, especially higher-molecular-mass RSS such as protein persulfide, the levels of which are increased by the growth factor.

Enterohemorrhagic Escherichia coli are a dangerous bacterium known to be harmful to the human body, with some infections even resulting in death. Given this danger, food factories are required to perform a quick bacterial test to confirm the absence of this pathogen prior to shipping. We have developed a novel molecular imprinting polymer (MIP) particle that has encapsulated gold nanoparticles (AuNPs) and which can function as both a receptor and an optical signal transmitter in biological systems. This MIP particle is artificially synthesized and can be engineered to specifically recognize and capture antigens on the bacterial cell membrane. In addition, MIP particles containing AuNPs generate strong scattered light signals, and binding of the MIP particles improves the optical intensity of the target bacterial cells. This enables clear visualization under a dark-field microscope and quantification of the target bacteria using the scattering light intensity. Here we describe the successful quantification of Escherichia coli O157 cells in real meat samples using this technology in conjunction with a simple labelling step.

We describe a new psocid genus and species, Burmesopsocus lienhardi Yoshizawa, based on a fossil specimen embedded in mid-Cretaceous Burmese (Kachin) amber. Phylogenetic analysis based on the morphological data strongly suggest that the species is a member of the suborder Psocomorpha and may belong to the infraorder Homilopsocidea. However, its familial placement could not be determined. Therefore, this species is treated here as incertae sedis within Homilopsocidea without assigning it to any known family. This is the oldest fossil record of Psocomorpha and represents the first occurrence of the suborder from Kachin amber. The present discovery of a mid-Cretaceous homilopsocid species will contribute greatly to calibrating the time tree of Psocodea.

Background:The association between cytochrome P450 (CYP) 2C19 genotypes and adverse events in patients treated with clopidogrel or prasugrel after percutaneous coronary intervention (PCI) in the Japanese population is unclear.Methods and Results:This study consisted of 1,580 patients whoseCYP2C19genotypes were assessed at Shiga University of Medical Science Hospital, and 193 clopidogrel-treated and 217 prasugrel-treated patients who were followed more than 1 year after receiving PCI were analyzed. Among 1,580 patients, the prevalence of normal, intermediate, and poor metabolizers was 32%, 49%, and 17%, respectively. Overall incidence of the primary outcome, defined as a composite of cardiovascular death, myocardial infarction, definite stent thrombosis, ischemic stroke, or major bleeding was not significantly different between the clopidogrel and prasugrel groups (adjusted hazard ratio [HR] 1.98, 95% confidence interval [CI] 0.85–4.61, P=0.12). Among patients with theCYP2C19loss-of-function (LOF) allele, however, the incidence of the primary outcome was significantly higher in the clopidogrel group (adjusted HR 3.19, 95% CI 1.10–9.24, P=0.03), whereas no difference was observed among patients without theCYP2C19LOF allele (adjusted HR 0.67, 95% CI 0.14–3.26, P=0.62).Conclusions:Among patients with theCYP2C19LOF allele, the use of clopidogrel was significantly associated with increased adverse events. Thus, further investigation is needed to establish the practical use ofCYP2C19genotyping.

Aims: Royal jelly, a creamy substance secreted by honeybees, has been reported to have beneficial effects against dyslipidemia and metabolic syndrome. However, the effects of royal jelly on atherogenesis remain unknown. Hence, we prospectively evaluated whether royal jelly augments vascular endothelial function, which can reflect early atherogenesis, in healthy volunteers. Methods: This was a single-center, double-blind, 1:1 randomized placebo-controlled study conducted from October 2018 to December 2019. A total of 100 healthy volunteers were randomly assigned to receive either royal jelly 690 mg or placebo daily for 4 weeks. The primary endpoint was augmentation in vascular endothelial function as assessed using the change in the reactive hyperemia peripheral arterial tonometry index (RH-PAT) index, and the secondary endpoints were the changes in liver function and lipid profiles between baseline and 4 weeks after enrollment. Results: The mean age of the participants was 35.0±9.3 years in the placebo group and 36.1±9.1 years in the royal jelly groups; 45% and 50% of the placebo and the royal jelly groups, respectively, were male. The percentage relative change in the RH-PAT index was significantly higher in the royal jelly group than in the placebo group (21.4%±53.1% vs. 0.05%±40.9%, P=0.037). The percentage relative changes in alanine aminotransferase and γ-glutamyl transpeptidase were significantly lower in the royal jelly group than in the placebo group (alanine aminotransferase: −6.06%±22.2% vs. 11.6%±46.5%, P=0.02; γ-glutamyl transpeptidase: −3.45%±17.8% vs. 4.62%±19.4%, P=0.045). Lipid profiles were not significantly different between the two groups. Conclusions: Royal jelly might have antiatherogenic property by improving vascular endothelial function. It also augmented liver functions in healthy volunteers.

This paper discusses the usage and meaning of the present progressive futurate from the perspective of English grammar teaching and proposes an alternative method of teaching this grammatical concept, which involves the use of films. This paper first analyzes the data and observations presented in related previous studies and verifies the validity of the following three specific constraints on the usage of the present progressive futurate that they proposed: the constraint on action, constraint on verb types, and proximity of time reference. The analyses of each constraint with data-in the form of dialogues-from English films highlight the grammatical features and meaning of the present progressive futurate. Real-life problems that are associated with English grammar teaching and are caused by these constraints are discussed. Subsequently, this paper proposes a method for teaching this futurate. This method involves comparing the usage of two of the more familiar English future expressions-will + infinitive and be going to-in the dialogues of the films such as Ocean's Twelve (2004) and Catch Me If You Can (2002). This comparison enables EFL learners to grasp the pragmatic differences among future expressions and better understand the meaning of the present progressive futurate.

Background:Optimal intensity is unclear for P2Y12receptor blocker therapy after percutaneous coronary intervention (PCI) in real-world clinical practice.Methods and Results:From the CREDO-Kyoto Registry, the current study population consisted of 25,419 patients (Cohort-2: n=12,161 and Cohort-3: n=13,258) who underwent their first PCI. P2Y12receptor blocker therapies were reduced dose of ticlopidine (200 mg/day), and global dose of clopidogrel (75 mg/day) in 87.7% and 94.8% of patients in Cohort-2 and Cohort-3, respectively. Cumulative 3-year incidence of GUSTO moderate/severe bleeding was significantly higher in Cohort-3 than in Cohort-2 (12.1% and 9.0%, P<0.0001). After adjusting 17 demographic factors and 9 management factors potentially related to the bleeding events other than the type of P2Y12receptor blocker, the higher bleeding risk in Cohort-3 relative to Cohort-2 remained significant (hazard ratio (HR): 1.52 95% confidence interval (CI) 1.37–1.68, P<0.0001). Cohort-3 compared with Cohort-2 was not associated with lower adjusted risk for myocardial infarction/ischemic stroke (HR: 0.96, 95% CI: 0.87–1.06, P=0.44).Conclusions:In this historical comparative study, Cohort-3 compared with Cohort-2 was associated with excess bleeding risk, which might be at least partly explained by the difference in P2Y12receptor blockers.
