タイトル: Predicting attitudes toward ambiguity using natural language processing on free descriptions for open-ended question measurements著者: Hitsuwari, Jimpei; Okano, Hirohito; Nomura, Michio抄録: Individual traits and reactions to ambiguity differ and are conceptualized in terms of an individual's attitudes toward ambiguity or ambiguity tolerance. The development of natural language processing technology has made it possible to measure mental states and reactions through open-ended questions, rather than predefined numerical rating scales, which have traditionally been the dominant method in psychological research. This study presented three ambiguity-related situations and responses collected online from 591 participants in an open-ended format. After the analysis with bidirectional encoder representations from transformers, correlations were calculated using scores from the numerical evaluation by conventional questionnaire, and a significant moderate positive correlatio ...

タイトル: Micro-patterned culture of iPSC-derived alveolar and airway cells distinguishes SARS-CoV-2 variants.著者: Masui, Atsushi; Hashimoto, Rina; Matsumura, Yasufumi; Yamamoto, Takuya; Nagao, Miki; Noda, Takeshi; Takayama, Kazuo; Gotoh, Shimpei抄録: The emergence of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) variants necessitated a rapid evaluation system for their pathogenesis. Lung epithelial cells are their entry points; however, in addition to their limited source, the culture of human alveolar epithelial cells is especially complicated. Induced pluripotent stem cells (iPSCs) are an alternative source of human primary stem cells. Here, we report a model for distinguishing SARS-CoV-2 variants at high resolution, using separately induced iPSC-derived alveolar and airway cells in micro-patterned culture plates. The position-specific signals induced the apical-out alveolar type 2 and multiciliated airway cells at the periphery and center of the colonies, re ...

タイトル: Adenosine triphosphate induces amorphous aggregation of amyloid β by increasing Aβ dynamics著者: Kuramochi, Masahiro; Nakamura, Momoka; Takahashi, Hiroto; Komoriya, Tomoe; Takita, Teisuke; Pham, Ngan Thi Kim; Yasukawa, Kiyoshi; Yoshimune, Kazuaki抄録: Amyloid β (Aβ) aggregates into two distinct fibril and amorphous forms in the brains of patients with Alzheimer’s disease. Adenosine triphosphate (ATP) is a biological hydrotrope that causes Aβ to form amorphous aggregates and inhibit fibril formation at physiological concentrations. Based on diffracted X-ray blinking (DXB) analysis, the dynamics of Aβ significantly increased immediately after ATP was added compared to those in the absence and presence of ADP and AMP, and the effect diminished after 30 min as the aggregates formed. In the presence of ATP, the β-sheet content of Aβ gradually increased from the beginning, and in the absence of ATP, the content increased rapidly after 180 min incubation, as reveal ...

タイトル: A comprehensive approach to characterize navigation instruments for magnetic guidance in biological systems著者: Blümler, Peter; Raudzus, Fabian; Schmid, Friederike抄録: Achieving non-invasive spatiotemporal control over cellular functions, tissue organization, and behavior is a desirable aim for advanced therapies. Magnetic fields, due to their negligible interaction with biological matter, are promising for in vitro and in vivo applications, even in deep tissues. Particularly, the remote manipulation of paramagnetic (including superparamagnetic and ferromagnetic, all with a positive magnetic susceptibility) entities through magnetic instruments has emerged as a promising approach across various biological contexts. However, variations in the properties and descriptions of these instruments have led to a lack of reproducibility and comparability among studies. This article addresses the need for standardizing the characterization of magnetic instruments, with a spec ...

タイトル: Microfluidic Device for Simple Diagnosis of Plant Growth Condition by Detecting miRNAs from Filtered Plant Extracts著者: Kawakatsu, Yaichi; Okada, Ryo; Hara, Mitsuo; Tsutsui, Hiroki; Yanagisawa, Naoki; Higashiyama, Tetsuya; Arima, Akihide; Baba, Yoshinobu; Kurotani, Ken-ichi; Notaguchi, Michitaka抄録: Plants are exposed to a variety of environmental stress, and starvation of inorganic phosphorus can be a major constraint in crop production. In plants, in response to phosphate deficiency in soil, miR399, a type of microRNA (miRNA), is up-regulated. By detecting miR399, the early diagnosis of phosphorus deficiency stress in plants can be accomplished. However, general miRNA detection methods require complicated experimental manipulations. Therefore, simple and rapid miRNA detection methods are required for early plant nutritional diagnosis. For the simple detection of miR399, microfluidic technology is suitable for point-of-care applications because of its ability to de ...

家庭寮新入寮生が4月2日（火）に入寮しました。 在寮生の先輩方は 入寮時間は始業式のため不在でしたが、在寮生が帰寮すると、早速同じフロアーの先輩が寮生活についていろいろと教えていました。 今年度は入寮日の4月2日より1号館の皆さんは自炊が始まりました。 入寮初日のメニューはカレーライスです。 家庭寮では、自炊初日は在寮生の先輩が、食材の配給方法、台所の使用方法等を教えながら、新入寮生のお部屋で一緒に夕食作りを行います。 写真は、1号館での自炊の様子です。 おいしいカレーが完成したようです。 2号館の皆さんは、食堂での夕食となります。 皆さん、黙食での夕食となりますが、おいしく夕食をいただいておりました。 夕食後は、新入寮生オリエンテーションを行い、寮生活についての説明を生活指 ...

タイトル: Seasonal diet partition among top predators of a small island, Iriomote Island in the Ryukyu Archipelago, Japan著者: Tobe, Alisa; Sato, Yukuto; Wachi, Nakatada; Nakanishi, Nozomi; Izawa, Masako抄録: Small islands tend to lack predators because species at higher trophic levels often cannot survive. However, two exceptional top predators—the Iriomote cat Prionailurus bengalensis iriomotensis, and the Crested Serpent Eagle Spilornis cheela perplexus—live on the small Iriomote Island in the Ryukyu Archipelago. To understand how these predators coexist with limited resources, we focused on their seasonal diets between which conflicts are considered to occur. To compare the diets, we used DNA metabarcoding analysis of faecal samples. In the summer, we identified 16 unique prey items from Iriomote cat faecal samples and 15 unique prey items from Crested Serpent Eagle faecal samples. In the winter, we identified 37 and 14, respectively. Using a non-metric multidimensional ...
