Peen


Definition:

Seen


Definition:

  • (p. p.) of See
  • () p. p. of See.
  • (a.) Versed; skilled; accomplished.

Example Sentences:

  • (1) At the early phase of the sensitization a T-cell response was seen in vitro, characterized by an increased spleen but no peripheral blood lymphocyte reactivity to T-cell mitogens at the same time as increased reactivity to the sensitizing antigen was detected.
  • (2) We determined whether serological investigations can assist to distinguish between chronic idiopathic autoimmune thrombocytopenia (cAITP) and immune-mediated thrombocytopenia in patients at risk to develop systemic lupus erythematosus (SLE); 82 patients were seen in this institution for the evaluation of immune thrombocytopenia.
  • (3) From these data it is possible to predict theoretically the apparent temperature difference as seen by an infrared scanner or radiometer with a detector of which the spectral detectivity, D (lambda), is known.

  • (5) The results of the evaluation confirm that most problems seen by first level medical personnel in developing countries are simple, repetitive, and treatable at home or by a paramedical worker with a few safe, essential drugs, thus avoiding unnecessary visits to a doctor.
  • (6) Augmentation of transformation response was generally not seen at 40 degrees C; incubation at that temperature was associated with decreased cellular viability.
  • (7) A marked overlap of input from the two eyes is an unusual feature for a diprotodont marsupial and has previously been seen only in the feathertail glider.
