Molecular basis of antibiotic sensing by the TetR family regulator CecR – a structural perspective

The FEBS Journal, EarlyView.
Escherichia coli CecR, a member of the TetR family regulators, senses selected antibiotics and activates the expression of a putative drug efflux pump. Although present in many pathogenic Enterobacteriales strains, CecR remains poorly characterized. We present the first CecR crystal structure, which reveals a unique tunnel‐like ligand‐binding cavity ...

The Effect of Graphene on the Fatigue Response and Failure Mechanism of Composite Materials: A Review

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT This review investigates the influence of graphene on the fatigue performance of polymer‐based composites, focusing on both unreinforced matrices and fiber‐reinforced composite laminates. Graphene materials, including nanoplatelets, graphene oxide, and hybrid nanostructures, offer exceptional mechanical, electrical, and barrier properties that

Development and validation of a novel approach for quantifying dimensions of the lateral ligaments in human ankle dissections

Journal of Anatomy, EarlyView.
Traditional measurement techniques in cadaveric dissection fail to account for the changes in soft tissue length during joint movement. We have developed a new, simple method to obtain more accurate measurements of ligament length and validated using the lateral ankle ligaments group.
