The pheromone component, frontalin (1,5-dimethyl-6,8-dioxabicyclo[3.2.1]octane) is thought to be formed in Dendroctonus spp. bark beetles through the cyclization of oxygenated 6-methyl-6-hepten-2-one (6-MHO). Unlike many of the isoprenoid pheromone components of bark beetles, there is no obvious immediate host conifer precursor

Methyl 2-octynoate is a synthetic fragrance which was first described to have sensitizing properties in 1935. It is one of the 26 fragrances to be labelled on the ingredient list according to current European cosmetics regulation. To report the experience

Collectively, the data in both humans and murine models of human primary biliary cirrhosis (PBC) suggest that activated T cells, particularly CD8 T cells, play a critical role in biliary cell destruction. Under physiological conditions, T-cell activation involves two critical

Rats given 2-octynoic acid by intraperitoneal injection excrete elevated amounts of medium-chain dicarboxylic acids and other acidic metabolites usually associated with human medium-chain acyl-CoA dehydrogenase deficiency. Onset of this organic acid profile is immediate and lasts for approximately 24 h.

Our laboratory has hypothesized that xenobiotic modification of the native lipoyl moiety of the major mitochondrial autoantigen, the E2 subunit of the pyruvate dehydrogenase complex (PDC-E2), may lead to loss of self-tolerance in primary biliary cirrhosis (PBC). This thesis is
