Example Sentences:

(13) The abnormalities were predominantly confined to the posterior pole and ranged from many small (100- to 200-microns) subretinal black ringlets to single large (2- to 3-disc diameter) geographic lesions.
(14) Brown bodies, formed by coelomocytes surrounding foreign material, accumulated in the posterior region of the animal around the cloacal suspensors; these eventually were eliminated through a ringlet of ducts connecting the coelomic cavity with the external environment.

Singlet
Definition:
(n.) An unlined or undyed waistcoat; a single garment; -- opposed to doublet.
Example Sentences:
(1) Quantitative singlet-singlet energy-transfer measurements were carried out to determine changes in the distance between the two Met-84 H4 sites within the same nucleosome following conformational transitions which we have reported earlier.
(2) In neutral or basic aqueous solution guanine, guanosine, deoxyguanosine, guanylic acid, deoxyguanylic acid, thymine, and uracil reacted with singlet oxygen.

(4) The ESR spectrum exhibited a singlet (g = 2.0021) with a 5.4-G peak-to-peak linewidth.
(5) While hydroxyl radicals produce DNA strand breaks and sites of base loss (AP sites) in high yield and react with all four bases of DNA, singlet oxygen generates predominantly modified guanine residues and few strand breaks and AP sites.
(6) These changes are detected by variations in the rate of decay of the excited singlet state of pyrene after pulsation with a 10-nsec ruby laser flash.
(7) This has been demonstrated using a separated-surface-sensitizer system for generating chemically pure singlet oxygen, eliminating most of the complications that arise with singlet oxygen generation by conventional photosensitization.
(8) Since all the sulfhydryl groups of beta-crystallin are known to be exposed on the surface of the protein (Andley et al, 1982, Biochemistry 21, 1853), these results suggest that the pronounced changes in conformation of beta-crystallin by singlet oxygen may be due to a rapid loss of the protein tertiary structure by oxidation of the sulfhydryl groups.
(9) The quantum yields for singlet oxygen formation via energy transfer from triplet alpha-terthienyl have been obtained from time-resolved measurements of its IR phosphorescence: these yields are in the 0.6-0.8 range in non-polar and polar (hydroxylic and non-hydroxylic) solvents.
(10) Attempts with various chemical sources of singlet oxygen to determine whether this species inactivates DNA did not give an unequivocal answer.

(12) This differs from results obtained with native enzyme, where pterin acts as a sensitizer via efficient singlet-singlet energy transfer to FADH2.
