Multivalent RNA‐Cleaving Agents on a Cubic Octameric Silsesquioxane Core
RNA‐cleaving agents on a cubic octameric silsesquioxane core were synthesized and characterized. Several catalytic systems of these structures were screened using hexaribonucleotide models. The best systems were then further used to study their catalytic efficiency in cleaving a HER2 mRNA model sequence. The induced cleavage sites were also determined.

New Insights Into the Three‐Dimensional Mechanics of the Flagellar Beat Cycle
ABSTRACT Advances in imaging at the molecular scale have provided greater detail concerning the three‐dimensional structure of the ciliary/flagellar axoneme. Additionally, it has recently been confirmed that electrostatic forces regulate the dynein‐tubulin interaction at the microtubule binding domain (MTBD) of dynein, and at the junction of the nexin ...

From Nonfinancial Reporting to Management Control: A GRI‐Based Sustainability Balanced Scorecard
ABSTRACT The integration of sustainability into strategic management systems has shifted from a reporting‐oriented exercise to a challenge of implementation, control, and accountability. Although the SBSC is widely acknowledged as a suitable framework to embed environmental and social objectives into strategy execution, its practical application ...
