Macroscopic Convective Fluid Flows Arising From Binding of Ions and Small Molecules to Proteins

open access: yesSmall, EarlyView.
The interaction of ions or small molecules with proteins causes convective flows due to the displacement of water from the hydration shell. As shown, the replacement of the nickel ion removed from urease by EDTA pre‐treatment results in binding‐induced convective fluid flow.

Endocytosis‐independent cytosolic entry of messenger RNA via fluorous bilayer zippering attenuating Toll‐like receptor signaling and enables ischemic tissue salvage

open access: yesSmart Molecules, EarlyView.
The present study establishes a paradigm shift in synthetic mRNA delivery through the convergence of three orthogonal chemistries—perfluoro‐acylation, bio‐orthogonal click cross‐linking, and disulfide reduction—within a single, modular polymer architecture. Abstract A fundamental constraint of conventional messenger RNA (mRNA) delivery systems is their

Exploring the potential of Textile Reinforced Concrete for corrosion‐insensitive retaining walls

open access: yesStructural Concrete, EarlyView.
Abstract In a context where durability concerns, particularly the corrosion of steel reinforcement, remain a critical challenge for conventional reinforced concrete structures under severe exposure, Textile Reinforced Concrete (TRC) is emerging as a promising alternative.

Inter-Session Repeatability of a Smartphone-Based Markerless System to Measure Segment Length and Lower-Limb Kinematics in Patients With End-Stage Knee Osteoarthritis. [PDF]

open access: yesOrthop Surg
The root mean square deviation (RMSD) across all kinematic variables between the test and retest sessions for walking and sit‐to‐stand. The “Total” RMSD represents the intra‐subject average of the walking and sit‐to‐stand tasks. ABSTRACT Background While kinematic analysis is crucial to characterize multi‐planar functional deficits in end‐stage knee ...
