大動脈弁を模擬した逆止弁を有する拍動流型VADの開発に関する実験的研究

拍動流を生成する左心補助人工心臓(LVAD)の開発を目的として，振動型ポンプに着目した．ここで，従来のポンプは逆止弁にJellyfish弁を用いてきたが，血液が弁を通過する際の剪断によって溶血の危険性が示唆された．そこで本研究では，大動脈弁を模擬した構造の逆止弁を用いることを提案し，ポンプシステムの構築およびポンプ特性の計測を行った．これを用いて送液実験を行った結果，本弁はjellyfish弁より高いポンプ性能を示した．しかし，ポンプの加振周波数によってP ...

Recent advances in multifunctional soft robots: A materials–structures–systems co‐design perspective for synergistic integration

FlexMat, EarlyView.
Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...

Evaluation of a novel fetal echocardiography training programme in two tertiary care obstetric Centres

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objectives Improving and maintaining high detection rates for major congenital heart disease (CHD) is a priority for successful prenatal anatomy screening programmes. The primary objective of this study was to evaluate the utility of on‐site multidimensional targeted training in fetal cardiac screening. Methods A prospective study evaluating a

Microbiome‐mediated plant‐soil feedbacks as a tool for resilient agriculture

iMetaOmics, EarlyView.
Translating plant‐soil feedbacks (PSFs) into reliable agricultural management requires shifting from input‐dependent practices toward endogenous, process‐driven crop resilience. To bridge this gap, we propose a predictive framework centered on three strategic interventions: engineering the crop holobiont, diversifying the soil habitat, and deploying ...
