Import of proteins into mitochondria.

Abstract: The biogenesis of mitochondria involves a close interaction between the nucleocytoplasmic and the mitochondrial genetic system. The majority of the mitochondrial proteins are synthesized on cytoplasmic ribosomes and transported into the organelle (1). The mechanism of this protein import has been under debate for many years (e.g., (2,3)). Recent experiments with yeast cells have shown that several cytoplasmic- ally made mitochondrial proteins are initially made as larger precursors, both in vitro as well as in pulse-labeled yeast spheroplasts (4,5). So far, larger precursors have been detected for the following cytoplasmically made mitochondrial proteins: the three largest subunits of the mitochondrial F1-ATPase (i.e., the α, β, and γ subunit, see (4)) and two subunits of the mitochondrial cytochrome bc1 complex (cytochrome c1 and subunit V; (5) and C. Cote, unpublished). Import of in vitro synthesized precursors into isolated mitochondria was demonstrated for the three largest F1-ATPase subunits; as an operational measure of import, we checked whether any of the polypeptides added to the mitochondria became resistant to externally added proteases (4).

2,2′:6′,2″-Terpyridines: From chemical obscurity to common supramolecular motifs

Abstract: This tutorial review describes the use of 2,2′:6′,2″-terpyridine (tpy) metal-binding domains in supramolecular chemistry. The origins of tpy chemistry are described and the reasons for its current importance in supramolecular chemistry are explained. Examples of tpy compounds in a wide variety of supramolecular chemistry are presented. The content will be of interest to organic, inorganic, supramolecular and nanoscale chemists.

ECCO Guidelines on Therapeutics in Crohn's Disease: Surgical Treatment

Abstract: This article is the second in a series of two publications relating to the European Crohn's and Colitis Organisation [ECCO] evidence-based consensus on the management of Crohn's disease. The first article covers medical management; the present article addresses surgical management, including preoperative aspects and drug management before surgery. It also provides technical advice for a variety of common clinical situations. Both articles together represent the evidence-based recommendations of the ECCO for Crohn's disease and an update of previous guidelines.
