(19) Of eighteen such transductants sixteen failed to show phase variation, and on transduction back to Salmonella each structural gene for a phase-2 flagellin (or at least for its antigenically determinant part) now behaved as an allele of H1, presumably in consequence of incorporation in the hag region of the K12 recipient, in place of H1-i ah1.
(20) It was shown that at HAg greater than or equal to 25% the strains used for antigen and antibody generation were closely related and at HAg less than or equal to 6.25% belonged to different subtypes.
Mossy
Definition:

(superl.) Resembling moss; as, mossy green.
Example Sentences:

(2) The developmental pattern of hippocampal mossy fiber (dentate granule cell axon) innervation to the pyramidal cell layer was examined with anterograde transport methods.
(3) The decrease in cerebellar cGMP content elicited by haloperidol can be differentiated from that elicited by diazepam; perhaps haloperidol reduces the mossy fiber input to the cerebellum.
(4) The role of intracellular calcium in an APV-insensitive form of long-term potentiation (LTP) has been studied at the hippocampal mossy fiber synapse.
(5) A study of seizure activity and neuronal cell death produced by intracerebroventricular kainic acid had suggested that seizures conveyed by the hippocampal mossy fibers are more damaging to CA3 pyramidal cells than seizures conveyed by other pathways.
(6) These results demonstrate that serotonergic fiber input from DR can suppress the efficacy of mossy and climbing fiber synaptic action on PC, or decrease the responsiveness of PC itself to afferent synaptic action.
(7) In the rat, neonatal irradiation produces a destruction of dentate granule cells and prevents the development of the mossy fibre-CA3 pyramidal cell synapse.

(11) The quantitative and topographical differences in the origin of mossy fibers suggest that these lobules may subserve slightly different functions.
(12) A highly positive correlation was found, in both species, between the synaptic surface and the number of agranular vesicles per unit volume of mossy fiber endings, while no correlation was found between the synaptic surface and numerical densities of coated and dense core vesicles.
(13) The distribution of mossy fiber terminals originating from the lower thoracic-higher lumbar spinal cord was compared to the distribution of zebrin I bands.
(14) Taurine localization to cerebellar mossy fibers and to fibers in the molecular layer of the dentate gyrus may be more consistent with a proposed neuromodulator role of taurine.
