Present status of volatile ruthenium in analytical chemistry and health physics.
核分裂によって生じる放射性白金族元素の中で生成量の最も多いRuは多くの原子価をとり,化学的性質が複雑なばかりでなく,8価の酸化物まで作って揮発するため,関連する研究や産業上の難問になっていた。近年はRuの複雑な化学的性質を触媒等に利用しようとする基礎研究が盛んであるが,原子力分野でも燃料再処理のダウンストリームを中心に,この困難克服のための研究が活発に行われるようになっている。本稿では,放射性Ruの研究の展望と揮発性Ruの基本的性質を基礎にして,近年の分離分析への応用環境試料分析における揮散,生体での挙動と被曝線量評価の問題点について述べる。

Els Fonaments canviants de la química analítica [PDF]
The features of the physico-chemical background of analytical chemistry, as it was viewed during the first half of this century, is first described. The impact of the massive introduction of instrumentation and separation techniques is discussed, and the

Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Molecular bases of circadian magnesium rhythms across eukaryotes
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...
