Starch storage capacity of sapwood is related to dehydration avoidance during drought.

Premise: The xylem tissue of plants performs three principal functions: transport of water, support of the plant body, and nutrient storage. Tradeoffs may arise because different structural requirements are associated with different functions or because suites of traits are under selection that relate to resource acquisition, use, and turnover. The structural and functional basis of xylem storage is not well established.

Intraosseous infusions via the calcaneus.

Objectives: To demonstrate that intraosseous infusions via the calcaneus could deliver fluids to systemic veins and that intraosseous infusions do not require bones with medullary cavities. To demonstrate that intraosseous infusions could be successful in adults.

Design: Ten adult cadavers were injected with 16 gauge intraosseous needles and infused with 10 ml of methyl green dye at a concentration of 10 mg/ml.
