Simultaneous Extraction and Depolymerization of Condensed Tannins from Chinese Bayberry Leaves for Improved Bioavailability and Antioxidant Activity.

J Agric Food Chem 2021 Sep 17. Epub 2021 Sep 17.

College of Biosystems Engineering and Food Science, Zhejiang Key Laboratory for Agro-Food Processing, Fuli Institute of Food Science, Zhejiang R & D Center for Food Technology and Equipment, Zhejiang University, Hangzhou 310058, PR China.

Biorefineries of polyphenols from plant leaves maximize their commercial value for developing biomedicines and nutrients. However, condensed tannins (CTs) constitute extensive polyphenols from plant leaves, which hinders the maximization due to extremely low bioavailability. Therefore, a simple, and sustainable one-step method was established to simultaneously extract polyphenols and depolymerize CTs with only endogenous flavan-3-ols from Chinese bayberry leaves via acid catalysis, which markedly improved the bioavailability of total polyphenols.

The injectable composite resin technique: biocopy of a natural tooth - advantages of digital planning.

Int J Esthet Dent 2021 Aug;16(3):280-299

The injectable composite resin technique is a minimally invasive and purely additive procedure that uses a transparent silicone index and flowable composite resin to translate the restorative plan from the wax-up to the final restoration. Its minimally invasive nature means that it can preserve tooth structure as it may not require hard tissue reduction. It is also an indirect/direct molding technique that allows the clinician to perform a direct restoration based on a proper analysis and planning. Read More
