In Vivo Imaging of Reactive Oxygen Species in a Murine Wound Model.

J Vis Exp 2018 Nov 17(141). Epub 2018 Nov 17.

Hansjörg Wyss Department of Plastic Surgery, New York University School of Medicine;

The generation of reactive oxygen species (ROS) is a hallmark of inflammatory processes, but in excess, oxidative stress is widely implicated in various pathologies such as cancer, atherosclerosis and diabetes. We have previously shown that dysfunction of the Nuclear factor (erythroid-derived 2)-like 2 (Nrf2)/ Kelch-like erythroid cell-derived protein 1 (Keap1) signaling pathway leads to extreme ROS imbalance during cutaneous wound healing in diabetes. Since ROS levels are an important indicator of progression of wound healing, specific and accurate quantification techniques are valuable. Read More

Augmented External Fixation of Ulnar Carpometacarpal Joint Fracture Dislocations.

Tech Hand Up Extrem Surg 2018 Nov 30. Epub 2018 Nov 30.

Cleveland Clinic.

Ulnar-sided carpometacarpal (CMC) joint fracture dislocations are relatively uncommon, frequently associated with fractures of the metacarpal base and/or hamate, and often sustained by young male individuals secondary to striking a hard object. The complexity of ulnar-sided CMC fracture dislocations necessitates careful restitution of anatomic alignment and joint congruency for mobility and stability. Miniaturization of the external fixation device has allowed application to the hand. Read More

Base-Free Iron Catalyzed Transfer Hydrogenation of Esters Using EtOH as Hydrogen Source.

Angew Chem Int Ed Engl 2018 Dec 2. Epub 2018 Dec 2.

Leibniz Institut fuer Katalyse e.V., Catalytic Conversion of Renewable Resources, Albert-Einstein-Strasse 29a, 18055, Rostock, GERMANY.

Herein, we report on the use of the iron pincer complex Iron-MACHO-BH, in the base-free transfer hydrogenation of esters with EtOH as a hydrogen source. More than 20 substrates including aromatic and aliphatic esters and lactones were reduced affording the desired primary alcohols and diols with moderate to excellent isolated yields. It is also possible to reduce polyesters to the diols with this method, enabling a novel way of plastic recycling. Read More
