Anthropogenic activities are increasingly threatening aquatic biodiversity, especially anadromous species. Monitoring and conservation measures are thus required to protect, maintain and restore imperilled populations. While many species can be surveyed using traditional capture and visual census techniques, species that use riverine habitats in a less conspicuous manner, such as sea lamprey Petromyzon marinus, can be more challenging to monitor.

Considering projected increases in high-magnitude rainfall events with climate change, major flooding events are expected to increase in many regions of the world. However, there is uncertainty about the effect of different flooding regimes and the importance of flood timing in structuring riverine habitats and their associated biotic communities.

Initiation of Clinical Trials in 1992 necessitated product manufacture under FDA Good Manufacturing Practice (GMP) requirements. To this end, all product components used were characterized to meet established requirements and processes and analytical methods were validated to confirm and document their utility and reproductibility. Manufacture of multiple 50+ liter lots of 10%g DCLHb under GMP requirements resulted in a pure and homogeneous product which reproducibly met a rigorous and complete set of product specifications.

Design: Ten patients who underwent coronary artery surgery were prospectively studied for the haematological effects of reinfusion of blood drained from the chest drain tubes after the operation by a Sorenson autologous transfusion system.
Setting: Surgery was performed at a private hospital and patient selection was made at the time of reinfusion.
