A water soluble extract from Uncaria tomentosa (Cat's Claw) is a potent enhancer of DNA repair in primary organ cultures of human skin.

Cat's Claw (Uncaria tomentosa) water extracts, essentially free of oxindole alkaloids, have been shown to possess a broad spectrum of biological activity including DNA repair enhancement and antiinflammatory properties. These two biological mechanisms are key molecular targets to develop treatments that protect skin exposed to ultraviolet light from the sun. Because C-Med-100, a Cat's Claw water extract, is the only documented natural source of components that can up-regulate simultaneously both DNA repair and antiinflammation, its ability to modulate DNA repair in human skin organ cultures was undertaken.

Suture suspension platysmaplasty for neck rejuvenation revisited: technical fine points for improving outcomes.

Background: The suture suspension platysmaplasty technique for neck rejuvenation was introduced more than 13 years ago. Over the years and after a large number of procedures performed for all classes of neck deformities, a number of technical fine points evolved that resulted in even more aesthetically pleasing and predictable results. These technical fine points are presented in detail, and their direct anatomic effects are analyzed.

Long-term results of suture suspension platysmaplasty for neck rejuvenation: a 13-year follow-up evaluation.

Background: Neck rejuvenation has been one of the most important components in treatment for the aging face because the neck frequently is the first feature to show signs of aging. Several techniques have been described, but assessment of the long-term effects, although limited, has shown frequent recurrence of neck ptosis and the need for reoperation. The suture suspension technique was introduced 13 years ago.

Use of fibrin sealant in neck contouring.

Background: The "suture suspension" platysmaplasty technique has been shown to be an effective and reliable procedure over the last decade.

Objective: We investigated the effectiveness of fibrin sealant in reducing the recovery time after suture suspension platysmaplasty.

Methods: After contouring the neck with our standard suture sling, hemostasis was assured.
