Objective: Since the efficacy of mechanical thrombectomy (MT) for acute cerebral infarction due to large vessel occlusion has been proven, the time available for treatment has gradually increased. Currently, under certain conditions, treatment is indicated up to 24 h from onset. Based on neurological signs and imaging diagnosis, Stroke Treatment Guideline 2021 recommends initiation of MT within 6–24 h from onset. Herein, we retrospectively investigated the relationship between cerebral perfusion imaging evaluation and prognosis in patients with acute cerebral infarction due to large or median vessel occlusion.Methods: Fifty-one patients diagnosed with acute cerebral infarction due to large or median vessel occlusions in anterior circulation between November 2019 and December 2021 were divided into medical care and reconstructive therapy (including tissue plasminogen activator [t-PA] therapy and MT) groups. The primary outcome was changes in the National Institutes of Health Stroke Scale (NIHSS) at admission and 1 week after onset. Patients in the medical care group were divided into those whose NIHSS did not worsen and those whose NIHSS worsened. Those in the reconstructive therapy group were divided into those whose NIHSS improved and those whose NIHSS did not improve. We evaluated the relationship between improvement factors in acute neurological symptoms and penumbral and core volumes from computed tomography perfusion performed at admission.Results: Of 45 eligible patients, 10 received medical care without t-PA or MT and 35 underwent reconstructive therapy, including t-PA and MT. Among the 10 patients in the medical care group, 3 had worsening symptoms and 7 did not. The mean and median (interquartile range [IQR]) penumbra volumes were significantly higher in patients with worsening symptoms than in those without. The receiver operating characteristic (ROC) curve showed a threshold value of 28.6 mL with an area under the curve (AUC) of 0.952. Among the 35 patients in the reconstructive therapy group, symptoms improved for 29 but did not improve for 6. The mean and median (IQR) core volumes were significantly higher in patients whose symptoms did not improve than in those whose symptoms improved. The ROC curve showed a threshold value of 25 mL and an AUC of 0.632.Conclusion: Evaluation of penumbra volumes could detect cases with worsening symptoms in cases where medical care was performed, and evaluation of core volumes may detect cases with non-improved symptoms in cases that received reconstructive therapy.

This paper shows the development of the activities of the Tokyo General Construction Workers Union from 1947 to 1965 as a genealogy of the architectural movement in Japan after WWII. This union is an industrial labor union established by construction workers such as craftsmen in 1947. The postwar architectural movement was led by architects and focused exclusively on housing as a social issue. Therefore, we understood their activities concerning housing from the perspective of its relationship with architects and discussed its subsequent development.

We previously reported that black tea consumption for 12 wk reduced the risk of acute upper respiratory tract inflammation, and improved secretory capacity in individuals with low salivary SIgA levels (Tanaka Y et al. 2021. Jpn Pharmacol Ther 49: 273–288). These results suggested that habitual black tea consumption improves mucosal immunity. Therefore, in this study we evaluated the effect of black tea intake on gut microbiota, which is known to be involved in mucosal immunity, by analyzing the bacterial flora and the short-chain fatty acids (SCFAs) concentration of feces collected during the above clinical study. The clinical design was a randomized, single-blind, parallel-group, placebo-controlled study with 72 healthy Japanese adult males and females, who consumed three cups of black tea (Black Tea Polymerized Polyphenols 76.2 mg per day) or placebo per day for 12 wk. In all subjects intake of black tea significantly increased abundance of Prevotella and decreased fecal acetic acid concentration. Particularly in the subjects with low salivary SIgA levels, the change over time of total bacteria, Prevotella, and butyrate-producing bacteria, which are involved in normalizing immune function, were higher in the black tea group than in the placebo group. In subjects with low abundance of Flavonifractor plautii a butyrate-producing bacteria, black tea consumption significantly increased salivary SIgA concentration and the absolute number of Flavonifractor plautii. In conclusion, our results suggest that improvement of mucosal immunity via an increase in butyrate-producing bacteria in the gut may partly contribute to the suppressive effect of black tea consumption on acute upper respiratory tract inflammation observed in our previous report.

Background: Lower systolic blood pressure (SBP) is known to be associated with poor prognosis in heart failure (HF). We evaluated the efficacy and safety of sacubitril/valsartan according to baseline SBP tertiles in Japanese patients from the PARALLEL-HF study.Methods and Results: In all, 223 patients were stratified into tertiles according to baseline SBP (≤114 mmHg: n=75; >114 and ≤130 mmHg: n=76; and >130 mmHg: n=72). Patients with lower SBP (≤114 mmHg) had the highest median N-terminal pro B-type natriuretic peptide (NT-proBNP) concentrations at baseline (P=0.0184). No significant difference was observed between sacubitril/valsartan and enalapril for the composite outcome of cardiovascular death and HF hospitalization across SBP tertiles (P-interaction=0.2682). Although the P-interaction value was not significant (0.2106), a greater reduction in NT-proBNP with sacubitril/valsartan compared with enalapril was observed in patients with SBP >130 mmHg (P=0.0076). The incidence of hypotension-related events and reduction or discontinuation of treatment due to hypotension-related events was higher in the lower SBP subgroup, and these events were more frequent in the sacubitril/valsartan than enalapril group.Conclusions: The efficacy of sacubitril/valsartan compared with enalapril was consistent across baseline SBP tertiles in Japanese patients from the PARALLEL-HF study. Hypotension-related events were more common in patients treated with sacubitril/valsartan with lower SBP.

エンタテインメント性の評価は難しく,評価基準や実験手法が模索されている.エンタテインメントの本質を「心の動き」とすると,評価には体験中のリアルタイムな感情を観測する必要がある.そこで本研究では,リアルタイムな思考を観測する思考発話法を応用した,「あ」だけ発声する「あアラウド法」を提案する.あアラウド法は,実験参加者がタスク中に「あ」の大きさやトーンを変化させて感情を表現し,実験者が実験参加者の感情の強弱や種類を観測する手法である.「あ」は日常的に感動詞として使われているため,自然に感情を表現するのに適していると考察する.実験では「あ」が表現する感情の分析と,他の発声方法との比較を行い,リアルタイムな感情の観測手法としての有用性を調査する.実験結果からエンタテインメント性の評価への利用可能性を示す.

Objective: Cerebral venous sinus thrombosis (CVST) is one of the rare and severe complications of coronavirus disease 2019 (COVID-19) vaccines. CVST has also been reported to develop into dural arteriovenous fistula; however, there were no reports of dural arteriovenous fistula associated with COVID-19 vaccine-induced cerebral venous sinus thrombosis. Here, we describe a rare case of a transverse–sigmoid sinus dural arteriovenous fistula followed by CVST due to COVID-19 vaccination.Case Presentation: A 70-year-old patient presented with headache five days after receiving a second dose of COVID-19 vaccine. MRI showed a CVST in the superior sagittal sinus, left transverse sinus, and left sigmoid sinus. His headache improved after the administration of anticoagulant therapy. Six months later, a similar headache recurred, and cerebral angiography demonstrated a dural arteriovenous fistula in the left transverse sigmoid sinus and convexity dural arteriovenous fistulas in the left parietal cortex. The patient was treated twice with two sessions of transarterial embolization, and the shunts were completely occluded. His symptoms improved, and he was discharged with a modified Rankin Scale score of 0.Conclusion: Dural arteriovenous fistula can develop after CVST in association with COVID-19 vaccination.

Ultramafic rocks, i.e., peridotites and pyroxenites, occur in a variety of tectonic settings on Earth. Ultramafic rocks can form as accumulation of mafic minerals from basaltic to komatiitic melts and be a major component of the Earth's mantle. The origin and history of ultramafic rocks are expected to provide information on the processes of partial melting and melt migration/extraction in the mantle and on the tectonic evolution of geologic units containing ultramafic rocks. I study ultramafic rocks in metamorphic belts, ocean floor, and mantle sections of ophiolites. My career began with a study of the Horoman Peridotite Complex in the Hidaka metamorphic belt in Japan. The ultramafic rocks and associated mafic rocks in the Horoman body record a very complex evolutionary history from the mantle conditions to crustal conditions. It is difficult to constrain the tectonic setting affecting events in the Horoman Peridotite Complex. On the other hand, ultramafic rocks in the mantle section of ophiolites and abyssal peridotites directly recovered from ocean floor to study melting processes and melt-rock interactions in the mantle can be used to constrain their tectonic setting, or at least as analogs to these tectonic settings. Studies on the Oman ophiolite by Japanese groups and literature studies of other ophiolites suggest that many ophiolites are later modified by subduction-related magmatism. Several ophiolites are being studied to elucidate the maturing process by subduction-related magmatism. Simple partial melting and melt extraction is expected in the adiabatically upwelling mantle beneath the mid-ocean ridge. In fact, abyssal peridotites directly recovered from mid-ocean ridges provided a unique opportunity to elucidate these processes. Comparison of abyssal peridotites recovered from the mid-ocean ridges and arc regions (fore arc and back arc) is key to understand the differences in magmatic processes in the two regions. Ocean science with research vessels has a well-defined working hypothesis that can only be addressed by direct sampling from the seafloor. To understand a crucial issue in Earth science as to why plate tectonics occurs on Earth, it is essential to elucidate the life of the oceanic lithosphere from its birth to its subduction into the mantle. Direct sampling of oceanic lithosphere by drilling is the key to solving this issue. I would like to emphasize that members of the Japan Association of Mineralogical science can play an essential role in leading analyses of rock samples directly recovered from seafloor. Rock samples recovered from seafloor by drilling and any methodology, as well as samples from anywhere on Earth, should be published in as papers, and these data would help integrate knowledge about the history of the Earth and planet and its future.

Eating breakfast is very important for the health and development of children. However, few studies have explored the correlates of children’s academic performance. Therefore, we aimed to investigate the associations of breakfast and scholastic performance.Six hundred fifty-five children, aged 8 to 12 years, were surveyed using original questionnaires. Breakfast skipping was defined as having missed any food between waking and the commencement of morning school classes at least 1 school day during the past week.Eight percent of participants reported skipping breakfast at least once time per week. Children who ate breakfast everyday scored higher on Japanese language test than children who did not eat breakfast (71.6±18.9 vs 65.9±18.0, p<0.05). Furthermore, students who did not had breakfast had higher negative emotion than those who always ate breakfast.Breakfast is not only promoted to improve health, but also to improve scholastic performance. We suggest further studies on the relationship between meal content, and scholastic performance.

To evaluate a validity of values for manganese (Mn) and molybdenum (Mo) contents of rice described in the Standard Tables of Food Composition in Japan 2010, 15 samples of Japanese brown rice, 53 samples of Japanese polished rice and 10 samples of Chinese polished rice were collected and their Mn and Mo contents were measured. Mean values of Mn in the Japanese brown rice and polished rice were 1.90 and 0.81 mg/100 g, respectively, which were close to values described in the Standard Tables. Mean value of Mn in the Chinese polished rice was 0.77 mg/100 g, which was also close to the values in the Standard Tables. Among the 53 samples of Japanese polished rice, 45 samples (84.9%) showed the Mn contents ranged from 0.6 to 1.0 mg/100 g. These results indicate that the Mn values of rice described in the Standard Tables are highly reliable. On the other hand, mean values of Mo in the Japanese brown rice and polished rice were 63 and 59 µg/100 g, respectively, which were also close to the Standard Tables. However, 42 samples (79.2%) of the Japanese polished rice showed the Mo content of less than 65 µg/ 100 g and a little sample showed more than 2 times of the values of the Standard Tables. Molybdenum contents in the Chinese rice showed higher values and variation than the Japanese rice. These results indicate that a large part of the Japanese rice showed a little lower Mo value than one described in the Standard Tables.
