Tube feeding
Tube feeding A way to provide food through a tube placed in the nose, the stomach, or the small intestine. A tube in the nose is called a nasogastric or nasoenteral tube. A tube that goes through the skin into the stomach is called a gastrostomy or percutaneous endoscopic gastrostomy (PEG). A tube into the small intestine is called a jejunostomy or percutaneous endoscopic jejunostomy (PEJ) tube. Also called enteral nutrition.
RELATED TERMS--------------------------------------
Food
Any substance eaten to provide nutritional support for the body.
Stomach

Gastrostomy
An artificial opening from the stomach to a hole (stoma) in the abdomen where a feeding tube is inserted. See also enteral nutrition.
Percutaneous
Passing through the skin.
Enteral
Pertaining to the small intestine. As in enteral nutrition. Also called enteric.

Telomerase
An enzyme composed of a catalytic protein component and an RNA template and that synthesizes the telomeric DNA at the ends of chromosomes. When active, telomerase can continually add to the length of the telomeres on the ends of chromosomes within a cell, thus conferring on that cell the ability to continue dividing past its normal lifespan.
Telomeres
"Caps" (made of repeated DNA sequences) found at the ends of chromosomes that protect the ends of the chromosomes from degradation. The telomeres on a chromosome shorten with each round of cell replication. Telomere shortening has been suggested to be a "clock" that regulates how many times an individual cell can divide (that is, when the telomeres of the chromosomes in a cell shorten past a particular point, the cell can no longer divide).
Tissue culture
See culture.
Totipotent cells
Stem cells that have unlimited developmental capability. The totipotent cells of the very early embryo (an embryo prior to the blastocyst stage) have the capacity to differentiate into extraembryonic tissues, membranes, the embryo, and all postembryonic tissues and organs.
