Biogenic Synthesis of Silver Nanoparticles with High Antimicrobial and Catalytic Activities using Sheng Di Huang (Rehmannia glutinosa).

Silver nanoparticles (AgNPs) are widely sought after for a variety of biomedical and environmental applications due to their antimicrobial and catalytic properties. We present here a green and simple synthesis of AgNPs utilizing traditional Chinese medicinal herbs. The screening of 20 aqueous herb extracts shows that Sheng Di Huang (Rehmannia glutinosa) had the most promising potential in producing AgNPs of 30±6 nm, with narrow size distribution and high crystallinity.

Modulation of thyroid hormone-dependent gene expression in Xenopus laevis by INhibitor of Growth (ING) proteins.

Background: INhibitor of Growth (ING) proteins belong to a large family of plant homeodomain finger-containing proteins important in epigenetic regulation and carcinogenesis. We have previously shown that ING1 and ING2 expression is regulated by thyroid hormone (TH) during metamorphosis of the Xenopus laevis tadpole. The present study investigates the possibility that ING proteins modulate TH action.

Modified Hanley procedure for management of complex horseshoe fistulae.

Purpose: Horseshoe fistulae are challenging due to configuration and sphincter involvement. In view of the new treatment options for fistulae (e.g.

Evaluation of artificial dermis neovascularization in an avascular wound.

Soft tissue coverage for avascular wounds is necessary in reconstructive surgery. Several authors have demonstrated successful treatment of problem wounds using artificial dermis. This study evaluates in an animal model the potential for neovascularization of artificial dermis in devascularized and avascular wound beds.
