Experimenteller Nachweis der metallbezogenen Funktion eines Cyanobactins

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Patellamide (Cyanobactine) werden von einer cyanobakteriellen Spezies in grosser Menge hergestellt. Diese zyklischen Peptide wurden in der Vergangenheit fast ausschliesslich auf ihre cytotoxischen Eigenschaften untersucht. Wir diskutieren neue experimentelle Daten, die auf eine Metallionen‐abhängige biologische Funktion der Patellamide schliessen ...

Ribozyme für die RNA‐katalysierte Methylierung und Markierung von RNA

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.
Ribozyme sind vielseitige Werkzeuge für die präzise Modifikation von RNA. Das Reaktionsspektrum in‐vitro‐selektierter Ribozyme reicht vom Einbau funktioneller Gruppen und Fluorophoren bis zu natürlichen RNA‐Methylierungen. Dieser Übersichtsartikel präsentiert Cofaktor‐abhängige Ribozyme für die positionsgenaue Markierung und Modifikation von RNA ...

Tree‐ring structure determines the temporal coordination between xylem growth and the gain in hydraulic conductivity in the outermost ring

New Phytologist, Volume 250, Issue 6, Page 3732-3746, June 2026.
Summary The study of seasonal xylem hydraulics has predominantly focused on embolism‐induced losses, whereas growth‐driven increases in hydraulic capacity have received little attention. We assessed the intra‐annual dynamics of xylem formation and gain of conductivity in the current‐year ring of three species with contrasting tree‐ring structure ...

Spin Crossover around Room Temperature: Effects of Remote Ligand Symmetry Breaking within Jäger‐Type Iron(II) Complexes

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 8, 25 May 2026.
Remote symmetry breaking in Jäger‐type iron(II) complexes shifts stepwise spin crossover (SCO) profiles to continuous profiles with transition temperatures around room temperature. In a bottom‐up approach, we studied the feedback of slight molecular modifications on the spin crossover (SCO) properties of otherwise structurally conserved iron(II ...

Le caractère changeant de la race en contexte migratoire: « À Montréal je ne suis pas considérée comme une personne blanche. Au Brésil, oui. »

Canadian Review of Sociology/Revue canadienne de sociologie, Volume 63, Issue 2, May 2026.
ABSTRACT This article draws on the analysis of semi‐structured interviews to compare the immigration experiences of queer individuals from the Global North with those of their counterparts from the Global South. It examines the process of racialization experienced by some of these individuals upon arrival in Quebec/Canada, the transformation of this ...

Care Pathways and Determinants in Essure® Contraceptive Implant Use and Removal: A Qualitative Study

Health Expectations, Volume 29, Issue 2, April 2026.
ABSTRACT Background Introduced in 2002, the Essure® implant was promoted as a minimally invasive permanent contraceptive. After widespread use, increasing reports of adverse effects led to its global withdrawal in 2018. This study explores the experiences of women in France who chose Essure®, focusing on their motivations and the factors leading to its
