What's the difference between preferential and selective?

Preferential


Definition:

  • (a.) Giving, indicating, or having a preference or precedence; as, a preferential claim; preferential shares.

Example Sentences:

  • (18) Simultaneous metabolic studies of human normal fibrinogen and asialofibrinogen in rabbits revealed only a modest decrease in the half-life of the asialoprotein compared to the intact protein, with no preferential uptake of the asialo-derivative by the liver.
  • (19) When fermented in preferential media it produces geldanamycin, nigericin, nocardamine, and a libanamycin-like activity.
  • (20) Rule-abiding parents can get a monthly stipend, extra pension benefits when they are older, preferential hospital treatment, first choice for government jobs, extra land allowances and, in some case, free homes and a tonne of free water a month.

Selective


Definition:

  • (a.) Selecting; tending to select.

Example Sentences:

  • (1) This selective review emphasizes advances in neurochemistry which provide a context for current and future research on neurological and psychiatric disorders encountered in clinical practice.
  • (2) The ability of azelastine to influence antigen-induced contractile responses (Schultz-Dale phenomenon) in isolated tracheal segments of the guinea-pig was investigated and compared with selected antiallergic drugs and inhibitors of arachidonic acid metabolism.
  • (3) Together these results suggest that IVC may operate as a selective activator of calpain both in the cytosol and at the membrane level; in the latter case in synergism with the activation induced by association of the proteinase to the cell membrane.
  • (4) Recently, the validity of the American Thoracic Society (ATS) standards for selection of spirometric test results has been questioned based on the finding of inverse dependence of FEV1 on effort.
  • (5) This death is also dependent on the presence of chloride and is prevented with the non-selective EAA antagonist, kynurenic acid, but is not prevented by QA.
  • (6) Microionophoretically applied excitatory amino acids induced firing of extracellularly recorded single units in a tissue slice preparation of the mouse cochlear nucleus, and the similarly applied antagonist 2-amino-5-phosphonovalerate (2APV) was demonstrated to be a selective N-methyl-D-aspartate (NMDA) receptor antagonist.
  • (7) Immunocytochemistry was used to visualize cytoskeletal structures and to assay selective disruption of neurofilaments by acrylamide.
  • (8) On removal of selective pressure, the His+ phenotype was lost more readily than the Ura+ Trp+ markers, with a corresponding decrease in plasmid copy number.
  • (9) Thus, saponin and ammonium chloride can be used to isolate whole infected erythrocytes, depleted of hemoglobin, by selective disruption of uninfected cells.
  • (10) Rapid overgrowth of all cultures with the E. coli necessitated the use of selective media containing antimicrobial agents to which the E. coli was sensitive.
  • (11) These effects are similar to those reported for AVP and phorbol esters, activators of protein kinase C. Forskolin and isoproterenol, which induce cAMP accumulation, activated extractable topoisomerase II (maximum 5-15 min after treatment), but not topoisomerase I. Permeable cyclic nucleotide analogs dBcAMP and 8BrcGMP selectively activated extractable topoisomerase II and topoisomerase I activities, respectively.
  • (12) Breast reconstruction should not be limited to the requiring patients, but should represent, in selected cases with favourable prognosis, an integrative and complementary procedure of the treatment.
