Brachytherapy, coronary artery (health) and biosphere (sh)


Brachytherapy, coronary artery (health)


Local radiation treatment within an artery to the heart. Coronary artery brachytherapy has been used to reduce the recurrence of blockage (obstruction) of a coronary artery after successful treatment of a blockage of a stent. A stent is a tubular structure that is implanted inside of a coronary artery to keep it open, thereby preventing a heart attack.





biosphere (sh)




Relatively thin life-supporting stratum of the earth's surface, extending from a few miles into the atmosphere to the deep-sea vents of the oceans.

The biosphere is a global ecosystem that can be broken down into Regional or local ecosystems, or biomes. Organisms in the biosphere are classified into trophic levels (see Food chain) and communities.
