Harnessing glycofluoroforms for impedimetric biosensing.

Glycans play a major role in biological cell-cell recognition and signal transduction but have found limited application in biosensors due to glycan/lectin promiscuity; multiple proteins are capable of binding to the same native glycan. Here, site-specific fluorination is used to introduce protein-glycan selectivity, and this is coupled with an electrochemical detection method to generate a novel biosensor platform. 3F-lacto--biose glycofluoroform is installed onto polymer tethers, which are subsequently immobilised onto gold screen printed electrodes, providing a non-fouling surface.

Using Purely Sinusoidal Voltammetry for Rapid Inference of Surface-Confined Electrochemical Reaction Parameters.

Alternating current (AC) voltammetric techniques are experimentally powerful as they enable Faradaic current to be isolated from non-Faradaic contributions. Finding the best global fit between experimental voltammetric data and simulations based on reaction models requires searching a substantial parameter space at high resolution. In this paper, we estimate parameters from purely sinusoidal voltammetry (PSV) experiments, investigating the redox reactions of a surface-confined ferrocene derivative.

Strength deficits in lower limb prosthesis users: A scoping review.

Background: Strength deficits may play a central role in the severity of balance, mobility, and endurance impairments in lower limb prosthesis users. A body of literature detailing the scope and specifics of muscle weakness in lower limb prosthesis users is emerging, but has yet to be summarized. A synopsis of strength deficits, and their impact on functional abilities in lower limb prosthesis users, may inform rehabilitation and research needs.

Autologous neurosensory retinal flap for closure of refractory macular hole in a patient with macular telangiectasia.

Purpose: This study explores autologous neurosensory autograph for a patient with a chronic full-thickness macular hole (FTMH) and idiopathic macular telangiectasia type 2 (IMT2).

Observations: The patient had a chronic 1355 μm FTMH and best corrected visual acuity (BCVA) of 2 logMAR units after two unsuccessful attempts to close the macular hole. Following a 25-gauge vitrectomy, a 2-disc diameter neurosensory autograft from the supertemporal retina was mobilized and secured with perfluoro-N-octane (PFO) tamponade.

Higher-Order Fermi-Liquid Corrections for an Anderson Impurity Away from Half Filling.

We study the higher-order Fermi-liquid relations of Kondo systems for arbitrary impurity-electron fillings, extending the many-body quantum theoretical approach of Yamada and Yosida. It includes, partly, a microscopic clarification of the related achievements based on Nozières' phenomenological description: Filippone, Moca, von Delft, and Mora [Phys. Rev.
