Tac


Definition:

  • (12) The complete transcriptional unit, incorporating the tac promoter and rrnB transcription terminators flanking the Pf1 coat protein gene, was excised from the expression plasmid and cloned into the intergenic space of bacteriophage R252, an fd bacteriophage that carries an amber mutation in its own major coat protein gene.

  • (16) Unlike other reported cases of Thp-CLL, fresh leukemic cells from this patient were positive with the anti-Tac monoclonal antibody, which recognizes the receptor for interleukin-2 (IL-2).
  • (17) SF CD4+ cells from RA and non-RA arthritides expressed the Tac antigen much more frequently than corresponding CD8+ cells (54 and 58% versus 16 and 17%).
  • (18) A Tn5tac1 insertion just inside the 3' end of cysQ, with its isopropyl-beta-D-thiogalactopyranoside-inducible tac promoter pointed toward the cysQ promoter, resulted in auxotrophy only when isopropyl-beta-D-thiogalactopyranoside was present; this conditional phenotype was ascribed to collision between converging RNA polymerases or interaction between complementary antisense and cysQ mRNAs.
  • (19) In addition, a monoclonal antibody (moAb) against the IL2 receptor (IL2-R; anti-Tac) inhibited the spontaneous colony formation from T-CFC of both groups of patients.
  • (20) The artificial secretory molecule of the IL-2 receptor named "bottom-less" receptor was able to react with anti-Tac antibody and to bind IL-2.

Tau


Definition:

  • (n.) The common American toadfish; -- so called from a marking resembling the Greek letter tau (/).

Example Sentences:

  • (1) For each temporal position of the independent noise, discriminability was a function of the ratio of the duration of the independent noise (tau) to the total burst duration.
  • (2) The 'intermediate' (tau 1) and 'slow' (tau 2) components were seen by curve fitting M-current deactivation currents.
  • (3) Tau protein can be transformed into an Alzheimer-like state by phosphorylation with a kinase activity from brain [Biernat et al.
  • (4) A "peeling" technique was used to estimate the time constants (tau 0 and tau 1) and coefficients (a0 and a1) of the first two exponential terms of the series of exponential terms whose sum represented the slope of the voltage response.
  • (5) The antibody to tau-labeled microtubules from normal human brains assembled in vitro but identically treated Alzheimer brain preparations had to be dephosphorylated to be completely recognized by this antibody.
  • (6) However, prepubertal heifers exposed to long-day photoperiods had reduced (P less than .01) urinary N tau-methylhistidine excretion compared with heifers given short-day photoperiods.
  • (7) In this study we confirmed this finding in two cases of PSP by using Bodian silver staining and immunohistochemistry with antibody to human tau protein.
  • (8) These data suggest that the induction of tau and MAP1 in response to NGF promotes microtubule assembly and that these factors are therefore key regulators of neurite outgrowth.
  • (9) (4) R(XY)(t,tau) is a biased estimator of the shape of h(t), generally over-estimating both its time to peak and its rise time.
  • (10) The monoexponential pattern of restitution was seen with model-independent descriptors of relaxation as well as with tau.
  • (11) The R. temporaria embryos at stages from insemination to the 1st cleavage division were incubated for 1 tau 0 in different saline solutions.
