Cheek and Chin Implants to Enhance Facelift Results.

Facial Plast Surg 2017 Jun 1;33(3):279-284. Epub 2017 Jun 1.

Facial Plastic Surgery Associates, 6655 Travis Street, Suite 900, Houston, Texas.

The traditional rhytidectomy addresses facial and neck aging as it relates to soft tissue laxity. The modern volumetric facelift provides optimal results by addressing not only skin laxity but also the loss of volume secondary to tissue atrophy and bony resorption. While multiple techniques including fat grafting, dermal fillers, and tissue resuspension are used to correct the tissue loss, alloplastic midface augmentation remains the most permanent method.

Two-Armed Activation of Bone Mineral Deposition by the Flavones Baicalin and Baicalein, Encapsulated in Polyphosphate Microparticles.

Am J Chin Med 2017 2;45(3):533-555. Epub 2017 Apr 2.

* ERC Advanced Investigator Grant Research Group at the Institute for Physiological Chemistry, University Medical Center of the Johannes Gutenberg University, D-55128 Mainz, Germany.

In this study, we investigated the effect of the two flavonoids, baicalin (baicalein 7-O-[Formula: see text]- d-glucuronic acid) and its aglycone, baicalein (5,6,7-trihydroxyflavone), after encapsulation into amorphous calcium polyphosphate (Ca-polyP) microparticles on mineralization of primary human osteoblasts (phOSB). Both flavonoids, which come from root extracts of Scutellaria baicalensis Georgi, are used in Traditional Chinese Medicine, and are nontoxic in cells up to a concentration of 3[Formula: see text][Formula: see text]g/ml. The morphogenetically active, energy-rich Ca-polyP particles with a stoichiometric P:Ca ratio of 1:2 are degraded by cellular alkaline phosphatase (ALP) to ortho-phosphate used for bone hydroxyapatite formation.
