Discovery and Characterization of a Distinctive Theaflavin-3-Gallate Isomer from with Potent Anticancer Properties Against Human Colorectal Carcinoma Cells.

Theaflavins, as key bioactive compounds of black tea, are garnering increasing attention. However, research predominantly focuses on theaflavin monomers derived from the enzymatic oxidation of -type catechins. In this study, we identify a unique stereoisomer of theaflavin-3-gallate (TF-3-G), named isoneoTF-3-G, in black tea from (), which is rich in -catechins.

An updated systematic review and meta-analysis on the efficacy of supine versus prone position for pediatric PCNL.

Background: The incidence of pediatric kidney stones is increasing with recurrence rates ranging from 35 to 50%. Supine percutaneous nephrolithotomy (PCNL) presents a viable alternative to the conventional prone position, offering specific benefits but also posing certain risks.

Objective: To update a previously published systematic review and meta-analysis comparing the efficacy of PCNL in the supine versus prone positions in children.
