  • (16) The infectious agent, S. typhi-murium, was isolated not only from several inmates but also from sick cows of the farm belonging to the home, in animal feed, from employees of the local butcher's shop, and finally in sludge from the local sewage plant.

  • (19) These elements originated from the wastewater sludge.
  • (20) Although ultrasound is effective in demonstrating the anatomical features of prolonged gallbladder stasis including sludge, stones, and thickened gallbladder wall, it cannot detect cystic duct patency.

Slug


Definition:

  • (n.) A drone; a slow, lazy fellow; a sluggard.
  • (n.) A hindrance; an obstruction.
  • (n.) Any one of numerous species of terrestrial pulmonate mollusks belonging to Limax and several related genera, in which the shell is either small and concealed in the mantle, or altogether wanting. They are closely allied to the land snails.

  • (n.) A ship that sails slowly.
  • (n.) An irregularly shaped piece of metal, used as a missile for a gun.
  • (n.) A thick strip of metal less than type high, and as long as the width of a column or a page, -- used in spacing out pages and to separate display lines, etc.
  • (v. i.) To move slowly; to lie idle.
  • (v. t.) To make sluggish.
  • (v. t.) To load with a slug or slugs; as, to slug a gun.
  • (v. t.) To strike heavily.
  • (v. i.) To become reduced in diameter, or changed in shape, by passing from a larger to a smaller part of the bore of the barrel; -- said of a bullet when fired from a gun, pistol, or other firearm.

  • (2) It was found that: the two cell types have the same basal adenylate cyclase activity; prespore cells and prestalk cells are able to relay the extracellular cAMP signal equally well; intact prestalk cells show a threefold higher cAMP phosphodiesterase activity on the cell surface than prespore cells, whereas their cytosolic activity is the same; intact prestalk cells bind three to four times more cAMP than prespore cells; no large differences in cAMP metabolism and detection were observed between cells derived from migrating slugs and culminating aggregates.
  • (3) We propose a model whereby a protein repressor, under the control of PKA, inhibits precocious induction of stalk cell differentiation by DIF and so regulates the choice between slug migration and culmination.
