Article Synopsis
- The red king crab and Japanese mitten crab are important for both their nutritional value and ecological research.
- A study focused on the changes in lipid profiles during the crabs' embryonic and larval stages, highlighting how triacylglycerols disappeared in early larvae but reappeared later with different compositions.
- The research revealed species-specific demands for polyunsaturated fatty acids, which could guide better diet selection in aquaculture practices.
Objective: The wide-ranging manipulations to the cardiovascular system that frequently occur during cardiac surgery can expose the brain to variations in its blood supply that could prove deleterious. As a first step to developing a resource suitable for monitoring such changes, we detected the hemodynamic events induced in the brain of a primate model, using high-density near-infrared spectroscopy combined with tomographic reconstruction methods and validated the findings using established radiologic and histologic techniques.
Methods: Continuous monitoring of the relative changes in the components of the cerebral hemoglobin signal was performed using high-density near-infrared spectroscopy (270 source-detector channel array) in anesthetized bonnet macaques with the brain exposed to induced ischemia and other acute events.
