Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Drafting the calmodulation playbook: Emerging structural insights into transient receptor potential channel regulation by calmodulin

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Calmodulin (CaM) is a ubiquitous calcium (Ca2+) sensor that translates intracellular Ca2+ signals into modulation of hundreds of effector proteins including ion channels. CaM is increasingly recognized as a key regulator of the transient receptor potential (TRP) channel family, yet the underlying ‘calmodulation playbook’ is only ...

Glutathione‐Related Metabolite Levels and Enzyme Activities in Depression: A Systematic Review and Meta‐Analysis

open access: yesNeuropsychopharmacology Reports, Volume 46, Issue 2, June 2026.
We conducted a systematic review and meta‐analysis to compare the levels of glutathione‐related metabolites. Our meta‐analysis indicated significantly decreased activity of glutathione‐peroxidase in patients with depression compared with healthy controls, while the levels of glutathione and glutathione reductase were not significantly different between

Synthesis, X‐Ray Analysis, Anticancer Activity, Computational, and in Silico Studies of New Thiophene Pyrazole Conjugates

open access: yesChemistryOpen, Volume 15, Issue 6, June 2026.
Two new thiophene–pyrazole derivatives, 8a and 8b, were synthesized from thiophene 3 precursor and fully characterized. The structure of 8a was confirmed by single‐crystal X‐ray diffraction, which revealed a nonplanar conformation stabilized by NH···O hydrogen bonding and weak intermolecular contacts.

Deprotonative C(sp3)/C(sp2)–H (Multi)Silylation of (Hetero)Arenes Mediated by NaTMP

open access: yesAngewandte Chemie, Volume 138, Issue 21, 18 May 2026.
An operationally simple protocol using a strongly basic sodium amide in combination with sterically emcumbered silicon electrophiles enables the deprotonative C–H (multi)silylation of a myriad of (hetero)arenes. Mechanistic investigations highlight the pivotal role of steric and coordination effects in controlling the regioselectivity and efficiency of
