  • (5) The possibility that mammalian DNA topoisomerase II is an intracellular target which mediates drug-induced DNA breaks is supported by the following studies using 4'-(9-acridinylamino)methane-sulfon-m-anisidide (m-AMSA): (a) a single m-AMSA-dependent DNA cleavage activity copurified with calf thymus DNA topoisomerase II activity at all chromatographic steps of the enzyme purification; (b) m-AMSA-induced DNA cleavage by this purified activity resulted in the covalent attachment of protein to the 5'-ends of the DNA via a tyrosyl phosphate bond.
  • (6) The calf pain prodrome of "tennis leg" requires rest and then a stretching program.
  • (7) A radioactive, photoactive Vinca alkaloid, N-(p-azido-[3,5-3H]-benzoyl)-N'-beta-aminoethylvindesine [( 3H]NABV) with pharmacological and biological activities similar to vinblastine was synthesized and used to identify specific Vinca alkaloid macromolecular interactions in calf brain homogenate by photoaffinity labeling.
  • (8) All four requirements were experimentally verified in calf trachea.
  • (9) A systematic structural comparison of several carp gamma-crystallins with high methionine contents was made by the secondary-structure prediction together with computer model-building based on the established X-ray structure of calf gamma-II crystallin.
  • (10) Native calf and rabbit erythrocytes bound the lectin, but human and rat erythrocytes required neuraminidase and trypsin treatment, respectively, for lectin binding to occur.

  • (12) Each calf was given a score based on macroscopic and microscopic lesions.
  • (13) Calf birth weight and gestational length decreased (P less than .01) as the number of calves born increased from one to two to three.
  • (14) Variability of basal blood flow in terms of standard deviations and in terms of coefficients of variation computed from duplicate determinations were significantly higher than for the other parameters and significantly more elevated in the forearm than in the calf.
  • (15) Each group of cattle consisted of six permanent members, two members fistulated at the oesophagus and one worm-free tracer calf.
  • (16) 2, and the calf serum were 34 and 73, and 480 mug per mouse respectively.

  • (18) Human liver slices were exposed to increasing concentrations of 1,2-propanediol up to a final concentration of 4.76 M in fetal calf serum.
  • (19) Pure cultures of oligodendrocytes or type 2-astrocytes can be generated in substantial amounts from CG-4 cells and maintained for several weeks in medium containing 5% fetal calf serum.
  • (20) Recent STM studies of calf thymus DNA and poly(rA).poly(rU) have shown that the helical pitch and periodic alternation of major and minor grooves can be visualized and reliably measured.

Calk


Definition:

  • (v. t.) To drive tarred oakum into the seams between the planks of (a ship, boat, etc.), to prevent leaking. The calking is completed by smearing the seams with melted pitch.
  • (v. t.) To make an indentation in the edge of a metal plate, as along a seam in a steam boiler or an iron ship, to force the edge of the upper plate hard against the lower and so fill the crevice.
  • (v. t.) To copy, as a drawing, by rubbing the back of it with red or black chalk, and then passing a blunt style or needle over the lines, so as to leave a tracing on the paper or other thing against which it is laid or held.
