Two cis-acting sequences, recognized by two erythroid-specific trans-acting factors, are involved in the regulation of the erythroid promoter of the human gene coding for porphobilinogen deaminase (PBGD). The first region, located at -70, binds the erythroid factor NF-E1, and point mutations within this region abolish the induction of transcription of this promoter during murine erythroleukemia (MEL) cell differentiation. The second region, located at -160, binds the erythroid-specific factor NF-E2 and the ubiquitous factor AP1. Using...

The MSE approach provides a simulation-based framework within which harvest strategies, stock assessment methods, performance indicators and research programmes can be compared. This approach has been used in the Australian South East Fishery (SEF) to assess harvest strategies for the over-exploited eastern gemfish resource and to compare different levels of discard monitoring for blue grenadier. The main challenges to use of the MSE approach in the SEF are poorly specified management objectives and the lack...

Altered expression of mitochondrial electron transport proteins has been shown in early preconditioned myocardial tissue. We wished to determine whether these alterations persist in the Second Window of Protection (SWOP) and if so, whether a favorable energetic state is facilitated during subsequent ischemia. Fourteen pigs underwent a SWOP protocol with ten 2-minute balloon inflations in the LAD artery, each separated by 2 minutes reperfusion. Twenty-four hours later, mitochondria were isolated from SWOP and SHAM pig...
