Given the size of the patient, having a sheath that is > 6 F in the brachial artery would pose significant risk. Also, due to the absence of a nub, other larger CTO devices would be difficult to use due to a lack of pushability by the supporting catheter or device.
Bee pollen is the pollen ball that has been packed by worker honeybees into pellets. Bee bread is the bee pollen with added honey and bee secretions and stored in brood cells, chambers of wood and mud created by female ground-nesting bees.
Bees collect plant pollen from many sources. To retrieve pollen to make honey and other materials in the hive, bees penetrate the outer shells of pollen with enzymes that remove rich nutrients. The outer shell of the pollen is included in its collection process.
