Case Report: Ocular Manifestation of Mantle Cell Lymphoma.

Significance: Mantle cell lymphoma (MCL) is a rare lymphoma that can present even more rarely in the orbit. Diagnosis, differentiation, and systemic treatment with the help of an oncologist are necessary for improved prognosis. Eye care providers must be vigilant when addressing ocular findings to determine next steps.

Time-dependent mucoadhesion of conjugated bioadhesive polymers.

The time-dependent bioadhesive performance of various polymers was evaluated using a texture analyzer apparatus and freshly excised rat small intestinal tissue. A series of novel bioadhesive polymers were prepared by conjugating L-phenylalanine, L-tyrosine, and L-DOPA to either a low molecular weight poly (butadiene-maleic anhydride) or a high molecular weight poly (ethylene-maleic anhydride). Bioadhesive force was characterized as a function of time relative to polycarbophil, a slightly cross-linked poly (acrylic acid)-derivative, revealing different fracture strengths and tensile work for each of the six backbone-side chain conjugations that were studied.

Bioinspired bioadhesive polymers: dopa-modified poly(acrylic acid) derivatives.

The one-step synthesis and characterization of novel bioinspired bioadhesive polymers that contain Dopa, implicated in the extremely adhesive byssal fibers of certain gastropods, is reported. The novel polymers consist of combinations of either of two polyanhydride backbones and one of three amino acids, phenylalanine, tyrosine, or Dopa, grafted as side chains. Dopa-grafted hydrophobic backbone polymers exhibit as much as 2.
