Abstract

AbstractReduction of styrene compounds was achieved by the simple method of adding more than 2.5 equivalents of an aqueous HI solution in chlorobenzene under refluxing conditions for 8 h to give the product in medium to excellent yields. There was no need to add further additional reagent and catalyst. HI was a specific reagent for this reduction reaction. Increment of the amount of HI was efficient to increase the yield rather than to elongate the reaction time. This reaction could be applied to compounds bearing halogen and sulfur atoms, which would act as reductive site and poisoning of the transition-metal catalyst, respectively. The yield was decreased in the case of the compounds bearing small substituent such as propyl and butyl groups on olefin. This reaction proceeded via the iodinated intermediate followed by the reduction of C-I bond. The reduction mechanism would contain the radical cleavage of the C-I bond. [ABSTRACT FROM AUTHOR]

Abstract

Background and ObjectivesDeclines in stroke admission, IV thrombolysis (IVT), and mechanical thrombectomy volumes were reported during the first wave of the COVID-19 pandemic. There is a paucity of data on the longer-term effect of the pandemic on stroke volumes over the course of a year and through the second wave of the pandemic. We sought to measure the effect of the COVID-19 pandemic on the volumes of stroke admissions, intracranial hemorrhage (ICH), IVT, and mechanical thrombectomy over a 1-year period at the onset of the pandemic (March 1, 2020, to February 28, 2021) compared with the immediately preceding year (March 1, 2019, to February 29, 2020).MethodsWe conducted a longitudinal retrospective study across 6 continents, 56 countries, and 275 stroke centers. We collected volume data for COVID-19 admissions and 4 stroke metrics: ischemic stroke admissions, ICH admissions, IVT treatments, and mechanical thrombectomy procedures. Diagnoses were identified by theirICD-10codes or classifications in stroke databases.ResultsThere were 148,895 stroke admissions in the 1 year immediately before compared with 138,453 admissions during the 1-year pandemic, representing a 7% decline (95% CI [95% CI 7.1–6.9];p< 0.0001). ICH volumes declined from 29,585 to 28,156 (4.8% [5.1–4.6];p< 0.0001) and IVT volume from 24,584 to 23,077 (6.1% [6.4–5.8];p< 0.0001). Larger declines were observed at high-volume compared with low-volume centers (allp< 0.0001). There was no significant change in mechanical thrombectomy volumes (0.7% [0.6–0.9];p= 0.49). Stroke was diagnosed in 1.3% [1.31–1.38] of 406,792 COVID-19 hospitalizations. SARS-CoV-2 infection was present in 2.9% ([2.82–2.97], 5,656/195,539) of all stroke hospitalizations.DiscussionThere was a global decline and shift to lower-volume centers of stroke admission volumes, ICH volumes, and IVT volumes during the 1st year of the COVID-19 pandemic compared with the prior year. Mechanical thrombectomy volumes were preserved. These results suggest preservation in the stroke care of higher severity of disease through the first pandemic year.Trial Registration InformationThis study is registered underNCT04934020.

Abstract

東京都は2019年6月に北硫黄島において総合的な自然環境調査を行った。本調査は、北硫黄島の自然環境の解明のみならず、2017年に調査が為された同じ火山列島に位置する南硫黄島の自然環境を再評価する上でも重要である。北硫黄島は周囲の有人島から遠く離れた無人島であること、湾が無いため泳いで上陸する必要があること、急峻な地形のため島上部の調査を行うには山岳技術を要することから、難易度の極めて高い調査フィールドといえる。したがって、遠征調査を行うには念入りな計画準備が必要となる。本稿では今後の北硫黄島および他の離島調査を計画する際に資するよう、今回の遠征調査の準備、訓練、ルート工作、安全管理等について記録した。, In June 2019 the Tokyo Metropolitan Government conducted an extensive natural environment expedition on Kita-iwoto Island in the Japanese archipelago. This expedition was important not only for determining the environmental state of Kita-iwoto, but also for re-evaluating the findings of a similar survey conducted on Minami-iwoto Island in 2017. Both surveys are vital to conservation efforts in the archipelago. Kita-iwoto is an isolated, uninhabited island that is exceptionally difficult to access; the lack of a bay necessitates swimming to shore, while the steep topography in the more elevated areas of the island requires the use of mountaineering techniques to complete surveys. Therefore, careful planning and preparation were required for the expedition. Here, we detail the preparation, training, route selection, and safety management measures undertaken to complete the expedition, to serve as a record for future research activity planning on Kita-iwoto and other remote islands.

Abstract

Development of organic fluorophore is an important theme. Especially, the fluorophores with longer fluorescence peaks are useful to biological probes. One of the methods to change the fluorescence peak is the introduction of substituents. However, opposing characteristics of the substituents lead to different changes in the fluorescence peaks. Furthermore, the introduction of the substituent also affects their electric properties. Thus, if the materials were developed with the substituent effect on the optical and electric properties separately, it will be useful to design the functional materials related to both optical and electric properties. Herein, we investigated the substituent effect of dipyrrolo[1,2-a:2′,1′-c]quinoxalines on fluorescence properties. We synthesized the compounds bearing electron-donating or electron-withdrawing substituents at the benzene ring on dipyrrolo[1,2-a:2′,1′-c]quinoxaline, which would have more direct influence on the optical properties. By introducing each substituent at the 6 position of dipyrrolo[1,2-a:2′,1′-c]quinoxaline, the bathochromic shift was observed in the fluorescence spectra. In the case of fluorine substituent, the change of the fluorescence peak reached was about 19 nm. Using a TDDFT calculation, we explained the reason for such a substituent effect that large on the increment of LUMO energy or decrement of HOMO energy occurred by introducing electron-withdrawing or electron-donating substituents at the 6 position, respectively. The substituent effect on the change of orbital energies is typical although the different characteristics of substituents resulted in the similar tendency about the change of fluorescence peak. Furthermore, with the introduction of phenyl substituents at the 3 and 10 positions, we achieved 40–50 nm longer fluorescence peaks compared with that of the original dipyrrolo[1,2-a:2′,1′-c]quinoxaline.
