The Alkaloid-Enriched Fraction of (Buxaceae) Shows Prominent Activity against .

In the course of our studies on antiprotozoal natural products and following our recent discovery that certain aminosteroids and aminocycloartanoid compounds from A. DC. (Apocynaceae) and L.

A sprayable luminescent pH sensor and its use for wound imaging in vivo.

Non-invasive luminescence imaging is of great interest for studying biological parameters in wound healing, tumors and other biomedical fields. Recently, we developed the first method for 2D luminescence imaging of pH in vivo on humans, and a novel method for one-stop-shop visualization of oxygen and pH using the RGB read-out of digital cameras. Both methods make use of semitransparent sensor foils.
