DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.

Fractional Flow Reserve Relates Stronger to Coronary Plaque Burden Than Nonhyperemic Pressure Indexes

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background The relationship between fractional flow reserve (FFR), resting full‐cycle ratio (RFR), instantaneous wave‐free ratio (iFR), resting distal pressure/aortic pressure (Pd/Pa), and plaque burden as well as phenotype requires further elucidation ...

Long-term outcomes after resting full-cycle ratio and deferral of revascularization

Clinical Research in Cardiology
Abstract Background Non-hyperemic pressure ratios are recommended to assess intermediate coronary lesions. Evidence on outcomes after deferral of revascularization based on resting full-cycle ratio (RFR) remains limited. Objective

Nutrition Status May be Related to Discordance of the Resting Full‐Cycle Ratio and Fractional Flow Reserve

Catheterization and Cardiovascular Interventions
ABSTRACT Background Clinical guidelines recommend using both hyperemic (fractional flow reserve [FFR]) and non‐hyperemic (instantaneous wave‐free ratio or resting full‐cycle ratio [RFR]) methods to evaluate coronary artery stenoses in patients with coronary artery disease (CAD).

Haplodiploidy, sex-ratio adjustment, and eusociality. [PDF]

, 2013
Hamilton's "haplodiploidy hypothesis" holds that inflated sororal relatedness has promoted altruistic sib rearing in haplodiploids, potentially explaining their apparent predisposition to eusociality.

Chemical State Detection and Charge Transfer in Complex Oxide Heterostructures via In Situ Auger Electron Spectroscopy

Advanced Functional Materials, EarlyView.
In situ Auger Electron Spectroscopy resolves oxidation states with high fidelity during the pulsed laser deposition of multivalent perovskite manganate and vanadate heterostructures. The chemical‐state signature is carried by the valence‐electron population of the transition‐metal cation, read out through the relative intensities of Auger fine ...

Hemodynamic assessment of intracranial atherosclerotic stenosis: comparison between invasive non-hyperemic pressure ratio and angiography-derived quantitative flow ratio

Frontiers in Neurology
ObjectivesTo evaluate the diagnostic accuracy of the quantitative flow ratio (QFR) for hemodynamic exploration of intracranial atherosclerotic stenosis, using the invasive cerebrovascular pressure ratio (CVPR) and resting full-cycle ratio (RFR) as ...
