The National Library of Medicine (NLM), on the campus of the National Institutes of Health in Bethesda, Maryland, is the world's largest medical library. The Library collects materials and provides information and research services in all areas of biomedicine and health care.
A substance present in all living cells that provides energy for many metabolic processes and is involved in making RNA. ATP made in the laboratory is being studied in patients with advanced solid tumors to see if it can decrease weight loss and improve muscle strength.
Industry:Medical
A right-handed spiral conformation; the a-helix has a pitch of 5. 4 A and has 3. 6 amino acid residues per turn; every main chain C=O and N-H group is hydrogen-bonded to a peptide bond 4 residues away; the peptide planes are roughly parallel with the helix axis and the dipoles within the helix are aligned, i.e. all C=O groups point in the same direction and all N-H groups point the other way; side chains point outward from helix axis and are generally oriented towards its amino-terminal end.
Industry:Medical
1) The phase of cell nucleus division following metaphase, in which the chromatids separate and migrate to opposite poles of the spindle.
2) The third phase of mitosis, in which the chromatids separate and migrate to opposite poles of the spindle.

1) A normal series of events in a cell that leads to its death.
2) Programmed cell death, the body's normal method of disposing of damaged, unwanted, or unneeded cells.
3) Apoptosis is the process of programmed cell death. It is used during early development to eliminate unwanted cells; for example, those between the fingers of a developing hand. In adults, apoptosis is used to rid the body of cells that have been damaged beyond repair. Apoptosis also plays a role in preventing cancer. If apoptosis is for some reason prevented, it can lead to uncontrolled cell division and the subsequent development of a tumor.
