  • (19) Juan Salgado, community leader creating a model for workforce development and training among immigrant communities through a holistic approach that addresses language skills, education and other barriers to entering the workforce Beth Stevens, neuroscientist revealing the heretofore unknown role of microglial cells in neuron communication and prompting a fundamental shift in thinking about brain development in both healthy and unhealthy states.
  • (20) Multiple pyogenic granuloma-like lesions occurring at punch graft sites are an unusual complication of hair transplantation heretofore unreported.

Whereupon


Definition:

  • (adv.) Upon which; in consequence of which; after which.

Example Sentences:

  • (1) The animals were killed after an abstinence of 4 weeks, whereupon the concentrations of noradrenaline (NA), dopamine (DA), serotonin (5-HT) and 5-hydroxyindole acetic acid (5-HIAA) were determined in the frontal cortex.
  • (2) Whereupon Madonna's PR guy Trevor Neilson (who doesn't seem to be too great at his job judging by the way in which a routine baby-hugging photo-op has descended into a hilarious international shitshow) hit back, giving quotes to The Globe and Mail reporter Geoffrey York.
  • (3) The hormone-receptor complexes are then translocated to the nucleus, in an "activated" form, whereupon they are bound to the target cell genome.
  • (4) Thresholds for the response are near 0.05 mA and the stimulus intensity curve is linear to 0.4 mA whereupon the pressure rise and tachycardia begin to approach a plateau value.
  • (5) In three patients, carbamazepine was withdrawn, whereupon the deposits disappeared in two and decreased in the third, who changed to another drug.
  • (6) The first of them came after 90 seconds, when, taking a free kick from the edge of the penalty box, his feint drew Johnston aside in the wall, whereupon Hidegkuti shot through the gap, to beat Gil Merrick, an erratic keeper that day.
  • (7) After observing a couple of weeks of bickering over who would get what time, we threatened to remove them again, whereupon the boys negotiated with each other and came up with an equitable time-sharing agreement.
  • (8) The scheme is as follows; phosphatidylcholine associated with high density lipoproteins exchanges with the erythrocyte membrane phospholipids, the neutral phospholipids undergo two dimensional translational and rotational motion and also flip between each layer of the bilayer thus becoming exposed to an intracellularly-located phospholipase-D, whereupon the choline is hydrolysed and released into the intracellular milieu.
  • (9) Nitrogen balances were not significantly different unless analysis of covariance was used to adjust for the nitrogen intakes, whereupon all treatment groups showed improved balance, especially the animals treated with the low IGF-I dose and des(1-3)IGF-I (both P less than 0.01).
  • (10) The ether phospholipid platelet-activating factor (PAF) has been generally assumed to be released into the extracellular environment by the cells of origin, whereupon it effects its well-known mediator functions.
