Fluorescence signaling molecularly imprinted polymers for antibiotics prepared via site-directed post-imprinting introduction of plural fluorescent reporters within the recognition cavity.

An antibiotic-imprinted cavity with two different fluorescent dyes was prepared by molecular imprinting and subsequent post-imprinting modifications (PIMs), for the readout of a specific binding event as a fluorescence signal. The fluorescent dyes were site-specifically introduced into the cavity using an orthogonal reversible bonding reaction, Schiff base formation, and a disulfide exchange reaction. The template molecule, comprising cephalexin connected to a Schiff base monomer and a disulfide monomer, was copolymerized with a crosslinker.

Conjugated-protein mimics with molecularly imprinted reconstructible and transformable regions that are assembled using space-filling prosthetic groups.

Conjugated-protein mimics were obtained using a new molecular imprinting strategy combined with post-imprinting modifications. An antibiotic was employed as a model template molecule, and a polymerizable template molecule was designed, which was composed of the antibiotic and two different prosthetic groups attached through a disulfide bond and Schiff base formation. After co-polymerization with a cross-linker, the template molecule was removed together with the prosthetic groups, yielding the apo-type scaffold.

Traumatic optic neuropathy caused by blunt injury to the inferior orbital rim.

A 48-year-old woman was struck on the right inferior orbital rim by a gardening device and immediately developed complete visual loss in the right eye. Clinical and imaging evaluations failed to disclose any damage to the globe or optic nerve or to their nearby soft tissues and bones. Within months, ipsilateral optic disc pallor, a nerve fiber bundle visual field defect, and a persistently subnormal visual acuity developed.
