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

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 ...

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

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 NH···O hydrogen bonding and weak intermolecular contacts.

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