タイトル: Genome-wide study suggests inheritance of personality traits in Toy Poodles and Miniature Dachshunds著者: Zemmoto, Chika; Matsumoto, Yuki; Arahori, Minori; Inoue-Murayama, Miho抄録: Domestic dogs exhibit significant diversity in both morphology and personality. Recent studies focusing on large-breed dogs reported the contribution of genetic factors to personality. However, the genetic influence in small-breed dogs remains unexplored. In the present study, we investigated the personality of two small-breed dogs using a questionnaire and genome-wide single-nucleotide polymorphism data obtained from 301 Toy Poodles and 183 Miniature Dachshunds using the Illumina CanineHD 230K SNP BeadChip. The factor analysis conducted on a questionnaire consisting of 39 items identified seven factors. Among the seven personality factors, ‘activeness’ in Toy Poodles and ‘human-directed sociability’ in Miniature Dachshunds had an estimated heritability of 0.425 (SE = 0.311) an ...

タイトル: Highly Efficient and Precise Rare-Earth Elements Separation and Recycling Process in Molten Salt著者: Hua, Hang; Yasuda, Kouji; Norikawa, Yutaro; Nohira, Toshiyuki抄録: Owing to the worldwide trend towards carbon neutrality, the number of Dy-containing heat-resistant Nd magnets used for wind power generation and electric vehicles is expected to increase exponentially. However, rare earth (RE) elements (especially Dy) are unevenly distributed globally. Therefore, an environmental-friendly recycling method for RE elements with a highly precise separation of Dy and Nd from end-of-life magnets is required to realize a carbon-neutral society. As an alternative to traditional hydrometallurgical RE separation techniques with a high environmental load, we designed a novel, highly efficient, and precise process for the separation and recycling of RE elements from magnet scrap. As a result, over 90% of the RE elements were efficiently extracted from the magnets using MgCl₂ an ...

タイトル: Analyzing Japan's Public Pension Reform in an Overlapping Generations Economy with Heterogeneous Households著者: Chen, Mingyan抄録: Japan's aging population and shrinking workforce are straining the public pension system. This study extends a Bewley-type overlapping generations model with heterogeneous households, more precisely accounting for Japan's tax system and two-tier pension structure, to analyze the effects of Japan's public pension reform proposals on individual households, the aggregate economy, and social welfare. The model calibrated to the 2022 Japanese economy suggests that cutting pension benefits by 20%, raising the eligibility age by five years, and removing the pension adjustments and suspensions under the statutory system would all increase private wealth, thus capital stock, labor supply, and total output in the long run if the pension tax rate and the consumption tax rate were adjusted to balance the government budget. With regard to the welfare ...

タイトル: Effect of antidepressants and social defeat stress on the activity of dorsal raphe serotonin neurons in free-moving animals著者: Koda, Masashi; Kawai, Hiroyuki; Shirakawa, Hisashi; Kaneko, Shuji; Nagayasu, Kazuki抄録: Major depressive disorder (MDD) is among the most common mental disorders worldwide and is characterized by dysregulated reward processing associated with anhedonia. Selective serotonin reuptake inhibitors (SSRIs) are the first-line treatment for MDD; however, their onset of action is delayed. Recent reports have shown that serotonin neurons in the dorsal raphe nucleus (DRN) are activated by rewards and play a vital role in reward processing. However, whether antidepressant treatment affects the DRN serotonin neuronal response to rewards in awake animals remains unknown. In this study, we measured the activity of DRN serotonin neurons in awake mice and determined the effects of antidepressants and chronic stress on DRN serotonin neuronal activity. We fou ...
