Although the first cases of classical swine fever were reported in 2018, no studies have explored this impact on wild boar populations in Japan. Comparing the relative abundance indices and age ratios in the wild boar population before and after the outbreak, we investigated the impact of classical swine fever virus on wild boar population dynamics in August 2017–December 2019. Relative abundance indices declined from 2017 to 2019 drastically, while there were no significant differences in age ratios throughout the study period. Consequently, wildlife managers should consider that wild boars continue to contract classical swine fever virus, and they should intensively implement countermeasures in agricultural lands and in pig farms, in addition to wild boar population management.

Objective Peripherally inserted central catheters (PICCs) are widely used in patients with hematologic malignancies. However, the risks of PICC-related complications during chemotherapy for acute myeloid leukemia (AML) are not fully understood. Methods We conducted a retrospective review of 128 adult patients with AML who received induction therapy by way of PICC insertion between 2012 and 2019. Results The median duration of PICC insertion was 30 days. The incidence rate of catheter-related bloodstream infection (CRBSI) was 2.4% at 30 days, and women were more likely to suffer from CRBSI than men. Local reactions at the insertion site were observed in 56 patients; however, these events did not predict CRBSI. The incidence rates of catheter-related thrombosis (CRT) were 1.6% at 30 days. Obesity put patients at an increased risk for CRT. Unexpected PICC removal occurred in 59 patients, and women were at a higher risk of catheter removal than men. Conclusion Low PICC-related complication rates, possibly associated with high rates of catheter removal, were observed during intensive chemotherapy for AML. Women and obese patients require careful monitoring of their PICC. Procedures to achieve appropriate PICC removal without increasing the complication rate need to be considered.

There is a possibility that classical swine fever virus outbreak has negative impacts on wild boar. To adequately manage native wild boar populations, wildlife managers need to gather the field data on wild boar and implement population management practices. We aimed to report the relative abundance index of wild boar before and after this outbreak. Our results showed that relative abundance index declined from 2017 (8.88 wild boars/100 trap days) to 2019 (2.03 wild boars/100 trap days), because of the negative impact of this virus and continuous culling programs. Although the eradication risk from the synergistic effect is low, wildlife managers need to consider the relationship between the trade-off between the risk of CSF and the conservation ecology risk of native species eradication.

視覚的に呈示された色情報の短期的保持が言語(言語的ワーキングメモリ)に依存するのか、あるいは視覚(視覚的ワーキングメモリ)に依存するのかは、当該色が色カテゴリーの境界をクロス(跨ぐ)するかしないかで異なるというモデルを提案した。機能的磁気共鳴脳画像法(fMRI)を用いて、代表的なワーキングメモリ課題であるNバック課題を導入してモデルを検証した。色の記憶における言語と視覚のワーキングメモリの寄与について検討した結果、基本色名で定義される色カテゴリーをクロスする条件では、左半球の下前頭回や下頭頂小葉が強く活動することがわかった。左の言語半球のこれらの領域の活性化は色の名前を音韻ループで保持する言語性ワーキングメモリが働いていることを示している。一方、同じ色カテゴリー内に留まる色差の小さい色の場合は、右半球の下前頭回が強く活動すること、つまり視覚的ワーキングメモリは視空間的スケッチパッドで保持されていることが示された。記憶すべき色刺激が左の音韻ループ(言語性ワーキングメモリ)で保持されるのか、右の視空間スケッチパッド(視覚性ワーキングメモリ)で保持されるのか、その認知負荷のバランスは色カテゴリーの境界を手がかりとした認知的方略によることが明らかになった。脳は色差に応じて色をことばであるいは知覚イメージで短期保持するのである。We proposed a model that colors could be memorized either in verbal or visual working memory depending on the color category borders. Using functional magnetic resonance imaging (fMRI), the model was tested by introducing a 2-back working memory task. We investigated the involvement of verbal and visual working memory in color memory. Colors between (cross) the categories defined by basic color names strongly activated the left inferior frontal gyms (IFG) and left inferior parietal lobule (IPL) corresponding to the phonological loop as verbal working memory, while colors within the category boarder strongly activated the right IFG corresponding to the visuospatial sketchpad as visual working memory. The choice of colors to memorize might modulated the cognitive load balance between the phonological loop and the visuospatial sketchpad.

We developed a new information management system, Protein Experimental Information Management System (PREIMS), which has the ontology-based functions for quality control, validation, scalability, and information sharing. Its contents are mainly experimental protocols for the analyses of protein structures and functions, and their results. They are stored separately in the PREIMS database (DB), as the ontology based protocol data and the result data. The synchrotron experimental information was stored as the latter result data in Extensible Markup Language (XML). Furthermore we converted those protocols in the format of Resource Description Framework (RDF) for integration with other biological information resources.

Objective: Postoperative complications and non-periprosthetic fractures (NPPFs), which was defined as a fracture existing non- periprosthetic implant, after total hip arthroplasty (THA) have a negative effect on the patients' ability to perform activities of daily living. Thus, investigating these incidences of patients after THA will be valuable as it lead to a more strategic physical therapy interventions and advanced research to prevent these problems. The purpose of this study was to investigate the incidence of postoperative complications related to implants and NPPFs in patients after THA, a more than 10-year follow-up. Methods: This is a retrospective cohort study. A total 892 patients with hip osteoarthritis who underwent primary THA were analyzed (age at surgery was 45-79 years; 805 women; the average follow-up period was 12.4-year). The postoperative complications related to implants and NPPFs were calculated using data from their medical records. Results: The postoperative complications occurred in 37 patients, and NPPFs occurred in 72 patients, who were significantly older, and hip and knee OA diagnosis, compared to patients without NPPFs ( p <.05). The most common cause of NPPFs was minor trauma. In patients aged ≥ 65 years, significantly more NPPFs occurred during the first year after surgery ( p <.05). Conclusion: More than 10-year after THA, the incidence of NPPFs was higher than that of postoperative complications related to implants. Older patients who had hip and knee OA were a significantly higher risk of developing NPPFs due to falls within the first year after surgery.
