What's the difference between annulet and bandlet?
Annulet
Definition:
(n.) A little ring.
(n.) A small, flat fillet, encircling a column, etc., used by itself, or with other moldings. It is used, several times repeated, under the Doric capital.
(n.) A little circle borne as a charge.
(n.) A narrow circle of some distinct color on a surface or round an organ.
Example Sentences:
(1) Binding of the ATP analog is shown to convert the enzyme to a circular clamp with an annulet, through which only a linear DNA can pass; subsequent circularization of the bound linear DNA forms a salt-stable catenane between the protein circular clamp and the DNA ring.
(2) Desmin immunoreactivity was noted also at the Z-bands of striated annulets, within areas of disordered myofibrils, such as sarcoplasmic masses, and in atrophic muscle fibers.
(3) Periarteriolar [H+] and [K+] were also measured because most large arterioles are in close proximity to venules such that the biochemical status of the periarteriolar tissue could be influenced by a large decrease in O2 availability in the annulet of tissue surrounding the venules.
Bandlet
Definition:
(n.) A small band or fillet; any little band or flat molding, compassing a column, like a ring.
(n.) Same as Bandelet.
Example Sentences:
(1) The n-bandlets straddle the midline glia and are known to produce most of the central neuroblasts.
(2) Cleavage geometry depends upon the presence or absence of the adjoining p bandlet, and if that bandlet is ablated, the pattern of o blast cell cleavages will undergo an abrupt transition several hours later.
(3) Ablations of ectodermal cell lines other than the n bandlets (o and p, or q) allowed the formation of normal distributions of neurons descended from the n bandlets.
(4) In each n and q bandlet, two blast cells are needed to generate one set of hemisegmental progeny, and two alternating classes of blast cells (nf and ns, qf and qs) can be distinguished after their first divisions.
(5) The results suggest that neither the commitment of q-bandlet cells to migrate nor the general lateral-to-medial direction of their migration depend on interactions with any other cell line.
(6) In each bandlet, older blast cells lie ahead of those born later.
(7) Neurons produced by cells that crossed the midline occupied the normal positions of their absent homologs, as demonstrated by morphometric analysis of normal and n-bandlet-deprived ganglia.
(8) The bandlets lie at the surface of the embryo beneath the squamous epithelium of a transient embryonic covering called the provisional integument.
(9) Segmental tissues of glossiphoniid leeches arise from rostrocaudally arrayed columns (bandlets) of segmental founder cells (primary m, n, o, p, and q blast cells) which undergo stereotyped sublineages to generate identifiable subsets of definitive progeny.
(10) Loss of the p bandlet is not, however, a sufficient condition for transfating of the o bandlet.
(11) This paper reports analyses of the differentiation and distribution of identified peripheral neurons and central 5-HT-containing neurons in embryos of the glossiphoniid leech Theromyzon rude that have been deprived of one of the bilaterally paired major ectodermal cell lines called the n bandlets.
(12) Seven patients aged 8 to 62 years with massive mitral regurgitation due to anterior leaflet prolapse related to rupture or elongation of the chordae tendinae underwent reconstructive mitral valvuloplasty between June 1984 and September 1985, consisting in transposition of a bandlet of the posterior leaflet and its chordae to the free edge of the anterior leaflet.
(13) Rather, loss of the p bandlet allows the o bandlet to shift into ectopic positions, and it is the ultimate position of the o bandlet that mandates which fate--O or P--the blast cells will take on.
(14) Primary n and q blast cells are about the same size and are produced at the same rate as blast cells for the o and p bandlets, but the longitudinal extent of their clones is roughly half that of the o and p blast cells' clones.
(15) This paper reports analyses of the effects of eliminating mesoderm from one or both sides of embryos of the glossiphoniid leech Theromyzon rude on the differentiation and distribution of ectodermal cells, especially identified peripheral neurons and central 5-hydroxytryptamine (5-HT)-containing neurons arising from the bilateral pair of cell lines called the n bandlets (n-kinship cells).
(16) Cells descended from a lone surviving n bandlet were abnormally distributed across both sides of the ventral midline.
(17) A midline glial fascicle resides at the primary axis of embryonic symmetry, alongside which teloblasts move as they generate their bandlets of stem cells.
(18) The o and p blast cell bandlets of the leech Theromyzon rude, which normally produce two different sets of identifiable cells designated the "O" and "P" fates, respectively, form an equivalence group: in embryos experimentally deprived of their p bandlet, the blast cells of the adjacent o bandlet may "transfate" and take on the P fate.
(19) To examine the dependence of long-distance cell migrations on positional cues provided by other tissues, embryos of Theromyzon rude were examined for the effects of selective ablation of various embryonic cell lines on the migration and final distribution of neural and glial precursor cells descended from the bilaterally paired ectodermal cell lines designated q bandlets.
