Background: ABO-incompatible kidney transplantation (ABOi-KTx) represents a possible solution to address the shortage of kidney donors. However, these transplants present immunological challenges, particularly when isoagglutinin titers are elevated pretransplant.
Methods: Single-center retrospective study describing clinical and biological outcomes of 8 patients who underwent ABOi-KTx with initial isoagglutinin titers ≥ 1/512.

In this study, palladium nanoparticles (Pd NPs) were successfully synthesized and supported on a cost-effective, eco-friendly magnetic lignosulfonate matrix using Hibiscus Rosasinensis L. leaf extract as a natural reducing and stabilizing agent (Pd@Fe₃O₄-lignosulfonate). The magnetic lignosulfonate prevented the aggregation of Pd NPs, enhanced the active surface area, and improved the hydrophilicity of the modified carbon paste electrode (CPE), thus boosting hydrogen production efficiency.

Importance: Speech recognition outcomes with a cochlear implant (CI) are highly variable. One factor suggested to correlate with CI-aided speech recognition is frequency-to-place mismatch, or the discrepancy between the natural tonotopic organization of the cochlea and the electric frequency allocation of the CI electrodes within the patient's cochlea.
Objective: To evaluate the association between frequency-to-place mismatch and speech recognition outcomes in a large cohort of postlingually deafened adult CI users, while controlling for various clinical factors known to be associated with those outcomes.

Extraction of gold from secondary resources such as electronic waste (e-waste) has become crucial in recent times to compensate for the gradual scarcity of the noble metal in natural mines. However, designing and synthesizing a suitable material for highly efficient gold recovery is still a great challenge. Herein, we have strategically designed rapid fabrication of an ionic crystalline hybrid aerogel by covalent threading of an amino-functionalized metal-organic polyhedra with an imine-linked chemically stable covalent organic framework at ambient condition.
