Aesthetic eyelid reconstruction.

The eyelids are critical in the protection of the conjunctiva and sclera of the globe and, in turn, the preservation of vision. Aesthetically, the position and shape of the eyelids define a distinctive frame for the eyes, and disproportions in any given individual are immediately obvious. Reconstruction of the eyelids must address both functional and aesthetic requirements.

A pilot randomized control trial of scar repigmentation with UV light and dry tattooing.

Objective: This study assessed the utility of focused scar injury with an ink-free tattooing technique combined with UV light exposure for the treatment of hypopigmented cervicofacial scars.

Study Design: Pilot prospective, randomized, control trial.

Subjects: Individuals with long-standing hypopigmented cervicofacial scars.

(3Z,6Z,9Z, 12Z, 15Z)-Pentacosapentaene, a key pheromone component of the fir coneworm moth, Dioryctria abietivorella.

The sex pheromone of the fir coneworm moth consists of a blend of (3Z,6Z,9Z,12Z,15Z)-pentacosapentaene and (9Z, 11E)-tetradecadienyl acetate. Analogous blends of polyunsaturated, long-chain hydrocarbons with much shorter chain aldehydes or alcohols recently have been discovered in three other moth species in the superfamily Pyraloidea. These combinations of components from two distinct structural classes may represent an important and widespread new pheromone blend motif within the Lepidoptera.
