Abstract
Numerous biomimetic molecular catalysts inspired by methane monooxygenases (MMOs) that utilize iron or copper-oxo species as key intermediates have been developed. However, the catalytic methane oxidation activities of biomimetic molecule-based catalysts are still much lower than those of MMOs. Herein, we report that the close stacking of a μ-nitrido-bridged iron phthalocyanine dimer onto a graphite surface is effective in achieving high catalytic methane oxidation activity. The activity is almost 50 times higher than that of other potent molecule-based methane oxidation catalysts and comparable to those of certain MMOs, in an aqueous solution containing H2O2. It was demonstrated that the graphite-supported μ-nitrido-bridged iron phthalocyanine dimer oxidized methane, even at room temperature. Electrochemical investigation and density functional theory calculations suggested that the stacking of the catalyst onto graphite induced partial charge transfer from the reactive oxo species of the μ-nitrido-bridged iron phthalocyanine dimer and significantly lowered the singly occupied molecular orbital level, thereby facilitating electron transfer from methane to the catalyst in the proton-coupled electron-transfer process. The cofacially stacked structure is advantageous for stable adhesion of the catalyst molecule on the graphite surface in the oxidative reaction condition and for preventing decreases in the oxo-basicity and generation rate of the terminal iron-oxo species. We also demonstrated that the graphite-supported catalyst exhibited appreciably enhanced activity under photoirradiation owing to the photothermal effect.

Abstract
California poppy or golden poppy (Eschscholzia californica) is the iconic state flower of California, with native ranges from Northern California to Southwestern Mexico. It grows well as an ornamental plant in Mediterranean climates, but it might be invasive in many parts of the world. California poppy was also highly prized by Native Americans for its medicinal value, mainly due to its various specialized metabolites, especially benzylisoquinoline alkaloids (BIAs). As a member of the Ranunculales, the sister lineage of core eudicots it occupies an interesting phylogenetic position. California poppy has a short-lived life cycle but can be maintained as a perennial. It has a comparatively simple floral and vegetative morphology. Several genetic resources, including options for genetic manipulation and a draft genome sequence have been established already with many more to come. Efficient cell and tissue culture protocols are established to study secondary metabolite biosynthesis and its regulation. Here, we review the use of California poppy as a model organism for plant genetics, with particular emphasis on the evolution of development and BIA biosynthesis. In the future, California poppy may serve as a model organism to combine two formerly separated lines of research: the regulation of morphogenesis and the regulation of secondary metabolism. This can provide insights into how these two integral aspects of plant biology interact with each other.

Abstract
A 73-year-old man underwent drug eluting stent (DES) implantation in the left anterior descending artery (LAD) 11 years ago and in the right coronary artery (RCA) 8 years ago. He suffered from chest tightness and was diagnosed with severe aortic valve stenosis. Perioperative coronary angiography revealed no significant stenosis and thrombotic occlusion of the DES. Five days before operation, antiplatelet therapy was discontinued. Aortic valve replacement was performed uneventfully. But he developed chest pain and transient loss of consciousness, electrocardiographic changes were observed on the 8th postoperative day. Emergency coronary angiography revealed thrombotic occlusion of the drug eluting stent in the RCA, despite the postoperative oral adoministration of warfarin and aspirin. Percutaneous catheter intervention (PCI) restored the stent patency. Dual antiplatelet therapy (DAPT) was initiated immediately after the PCI, and anticoagulation therapy with warfarin was continued. Clinical symptons of stent thrombosis disappeared immediately after the PCI. He was discharged 7 days after the PCI.

Abstract
A C4h symmetrically substituted phthalocyanine, 1,8,15,22-tertrakis(2,4-dimethylpent-3-oxy)phthalocyanine (H2 TdMPPc), was used to synthesize Tb3+ -phthalocyanine double-decker complexes ([Tb(TdMPPc)2 ]s). Because H2 TdMPPc has C4h symmetry, S,S, R,R, and meso isomers of [Tb(TdMPPc)2 ] were obtained depending on the difference in the direction of the coordination plane of two C4h -type phthalocyanines with respect to a central Tb3+ ion. We investigated the physical properties of these [Tb(TdMPPc)2 ] isomers, including their single-ion magnetic properties, and found that the spin-reversal energy barrier (Ueff ) of the meso isomer was apparently higher than that of the enantiomers. Detailed crystal structural analyses indicated that the meso isomer has a more symmetrical structure than do the enantiomers, thereby suggesting that the higher Ueff of the meso isomer originated from the more highly symmetrical structure.

Abstract
Advancements in synthetic biology have facilitated the microbial production of valuable plant metabolites. However, constructing complete biosynthetic pathways within a single host organism remains challenging. To solve this problem, modular co-culture systems involving host organisms with partial pathways have been developed. We focused on Escherichia coli, a general host for metabolite production, and Pichia pastoris (Komagataella phaffii), a novel synthetic biology host due to its high expression of biosynthetic enzymes. Previously, we reported the co-culture of E. coli cells, which produce reticuline (an important intermediate for various alkaloids) from glycerol, with P. pastoris cells, which produce the valuable alkaloid stylopine from reticuline. However, Pichia cells inhibited E. coli growth and reticuline production. Therefore, we aimed to improve this co-culture system. We investigated the pre-culture time before co-culture to enhance E. coli growth and reticuline production. Additionally, we examined the optimal concentration of Pichia cells inoculated for co-culture and methanol addition during co-culture for the continuous expression of biosynthetic enzymes in Pichia cells. We successfully established an improved co-culture system that exhibited an 80-fold increase in productivity compared to previous methods. This enhanced system holds great potential for the rapid and large-scale production of various valuable plant metabolites.

Abstract
BACKGROUND In older people, frailty has been recognized as an important prognostic factor. However, only a few studies have focused on multidimensional frailty as a predictor of mortality and readmission among inpatients with pneumonia. OBJECTIVE The present study aimed to assess the association between preadmission frailty and clinical outcomes after the hospitalization of older patients with pneumonia. DESIGN Single-center, retrospective case-control study. SETTING Acute phase hospital at Kobe, Japan. PARTICIPANTS The present study included 654 consecutive older inpatients with pneumonia. MEASUREMENTS Frailty status before admission was assessed using total Kihon Checklist (KCL) score, which has been used as a self-administered questionnaire to assess comprehensive frailty, including physical, social, and cognitive status. The primary outcome was a composited 6-month mortality and readmission after discharge. RESULTS In total, 330 patients were analyzed (median age: 79 years, male: 70.4%, median total KCL score: 10 points), of which 68 were readmitted and 10 died within 6 months. After multivariate analysis, total KCL score was associated with a composited 6-month mortality and readmission (adjusted hazard ratio, 1.07; 95% confidence interval, 1.02-1.12; p = 0.006). The cutoff value for total KCL score determined by receiver operating characteristic curve analysis was 15 points (area under the curve = 0.610). The group with a total KCL score ≥ 15 points had significantly higher readmission or mortality rates than the groups with a total KCL score < 15 points (p < 0.001). CONCLUSIONS Preadmission frailty status in older patients with pneumonia was an independent risk factor for readmission and survival after hospitalization.

Abstract
OBJECTIVES Although better diet quality is inversely associated with mortality risk, the association between diet quality and mortality remains unclear in frail and non-frail older adults. Thus, we aimed to examine this association in older Japanese adults. DESIGN A prospective cohort study. SETTING AND PARTICIPANTS We used the data of 8,051 Japanese older adults aged ≥65 years in the Kyoto-Kameoka study. MESUREMENTS Dietary intake was estimated using a validated food frequency questionnaire. Diet quality was evaluated by calculating the adherence scores to the Japanese Food Guide Spinning Top (range, 0 [worst] to 80 [best]), which were stratified into quartiles. Frailty status was assessed using the validated self-administered Kihon Checklist (KCL) and the Fried phenotype (FP) model. Survival data were collected between February 15, 2012 and November 30, 2016. Statistical analysis was performed using the multivariate Cox proportional hazard analysis and the spline model. RESULTS During the median 4.75-year follow-up (36,552 person-years), we recorded 661 deaths. After adjusting for confounders, compared with the bottom adherence score quartile, the top quartile was associated with lower hazard ratio (HR) of mortality in frailty (HR, 0.73; 95% confidence interval [CI], 0.54-1.00) and non-frailty, as defined by the KCL (HR, 0.72; 95% CI, 0.52-1.01). In the spline model, regardless of frailty status defined by the KCL and FP model, adherence score showed a strongly dose-dependent inverse association with mortality up to approximately 55 points; however, no significant differences were observed thereafter. This association was similar to the results obtained in individuals with physical, cognitive, and depression as domains of KCL in the spline model. CONCLUSIONS Our findings demonstrate an L-shaped association between diet quality and mortality in both frail and non-frail individuals. This study may provide important knowledge for improving poor diet quality in older individuals with frailty or domains of frailty.

Abstract
A 78-years-old woman was referred to our institution for the treatment of right subclavian artery (SCA) aneurysm. She previously underwent total arch replacement via median sternotomy approach. Preoperative computed tomography revealed a 55 mm sized SCA aneurysm. Stent graft was inserted from brachiocephalic artery to right common carotid artery via the graft anastomosed. The orifice of the right SCA was covered with stent graft inserted into the right common carotid artery-brachiocephalic artery and the right SCA was occluded with coils distal to the aneurysm, carotid-SCA bypass was performed with 8 mm ePTFE graft. Postoperative examination confirmed complete exclusion of the aneurysm and patency of the bypass graft. We thought that hybrid treatment for this patient was a less invasive alternative to conventional surgical procedure.

Abstract
A 76-year-old man with thoracic aortic aneurysm was admitted to our hospital. Aortic arch replacement was performed uneventfully. He suffered from abdominal pain 17 days after the operation. Computed tomography (CT) scan revealed a strangulated bowel obstruction, and we performed emergent open abdominal surgery. During the operation, we found an adhesion between the greater omentum and the retroperitoneum. The small intestine was intussuscepted into this site, and strangulated with necrosis of a 35-cm length. We performed a partial resection of the small intestine. We encountered rare strangulated bowel obstruction after open heart surgery due to adhesion of the great omentum in a patient without a history of abdominal surgery.

Abstract
A 73-year-old woman suffered from premature ventricular contraction( PVC) which could not be controlled by medications. Holter 24-hour continuous recording electrocardiogram (Holter ECG) revealed 22,706 PVC beats/day. Upon further examination, she was found to have severe aortic stenosis and mild insufficiency. Preoperative electro-physiological study and standard 12-lead electrocardiogram revealed that the PVC originated from myocardium under the left coronary cusp. Aortic valve replacement and intraoperative cryoablation were performed. Her postoperative course was uneventful, Holter ECG revealed 638 PVC beats/day. Clinical symptons of PVC disappeared immediately after surgery. She was discharged 19 days after the operation.

Abstract
This study aimed to evaluate the association between locomotive syndrome (LS) and daily physical activity (PA) in community-dwelling older adults. This cross-sectional study included 80 healthy Japanese older adults (40 men and 40 women; age: 60-79 years). Habitual daily PA was evaluated using a triaxial wrist accelerometer. Participants were divided into two groups based on the results of the two-step test, stand-up test, and 25-question geriatric locomotive function scale. Binomial logistic regression analysis was conducted to examine the statistical relationships between daily PA and category of LS, adjusting for age from adjusted odds ratio (adjusted OR) with the 95 percent confidence intervals (95%CI) and bootstrap 95%CI. The mean step count and time spent on moderate to vigorous physical activity (MVPA) were significantly higher among non-LS participants than among LS participants in women, but not in men. Logistic regression analyses indicated that spending longer than 28 min/day on MVPA was significantly associated with a lower likelihood of LS relative to short time category under 28 min/day in women (adjusted OR = 0.12, 95%CI = 0.02-0.59, bootstrap 95%CI = 0.01-0.43), but not in men. This study suggests that in community-dwelling older women, those with higher MVPA had lower odds of LS, and daily MVPA was associated with LS, but not in men. Therefore, the associations between LS and daily physical activity were partly dependent on sex differences.
