What's the difference between thereby and whereupon?

Thereby


Definition:

  • (adv.) By that; by that means; in consequence of that.
  • (adv.) Annexed to that.
  • (adv.) Thereabout; -- said of place, number, etc.

Example Sentences:

  • (4) The following model is suggested: exogenous ATP interacts with a membrane receptor in the presence of Ca2+, a cascade of events occurs which mobilizes intracellular calcium, thereby increasing the cytosolic free Ca2+ concentration which consequently opens the calcium-activated K+ channels, which then leads to a change in membrane potential.

  • (10) In addition, the menisci increase the femorotibial contact area, thereby relieving some of the pressure.
  • (11) Because haptenated cells can induce immunity if injected subcutaneously or into cyclophosphamide-pretreated recipients (thereby avoiding the induction of suppressor cells), we suggest that the activation of contrasuppressor cells by antigen-antibody complexes overrides suppressive influences in the host, allowing immunity to become dominant.
  • (12) This was overcome by using a continuous subcutaneous infusion pump which also enabled the effective daily dosage to be reduced and thereby adverse reactions to be avoided.
  • (13) These results suggest that CPZ interacts with smg p21B, smg GDS, or both, and thereby inhibits the smg GDS action, and that CPZ also interacts with the acidic phospholipids and thereby counteracts their inhibitory effect on the smg GDS action.
  • (14) Use of sunglasses that block all ultraviolet radiation and severely attenuate high-energy visible radiation will slow the pace of ocular deterioration and delay the onset of age-related disease, thereby reducing its prevalence.
  • (15) In recent years, apart from these well known risks, the immuno-suppressive effect of blood transfusions has been observed and thereby the possible adverse influence on the prognosis in cases of malignant disease.
  • (16) From this information, it would appear that it is possible that the mechanism for the prolonged effect of acupuncture in treating chronic pain is that the repeated activation of the physiological systems by which acupuncture inhibits pain, by the repeated acupuncture treatments, trains the body to continue this activity and thereby maintains the pain relief for a period of time after the last treatment.
  • (17) Among these are DNA exo- and endonucleases and DNA glycosylases which remove oxidatively damaged portions of the DNA molecule, thereby initiating excision-repair.
  • (18) Taken together, these findings indicate that IGFs can stabilize neuronal calcium homeostasis and thereby protect against hypoglycemic damage.
  • (19) Drugs known to improve memory, including physostigmine, pramiracetam and the muscarinic agonists, oxotremorine and RS 86, selectively induced analgesia in rats subjected to test before the shock plus the shock, thereby supporting a hypothesis of avoidance learning.
  • (20) The increased volume of flowing blood and increased stroke volume in athletes probably allows for a reduction in flow velocity and thereby a reduction in kinetic energy.

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.

  • (12) Severe leucopenia was observed in 2 patients, whereupon therapy was definitely withdrawn.
  • (13) Whereupon Gove went back into his customary role of baiting Hunt for making up Labour's education policy on the hoof.
  • (14) We report a case of a 20-year-ol women whose pineal region tumour was irradiated, whereupon a unilateral low-frequency resting and intention tremor developed.
  • (15) In the disk, the region proximal to the RNA binding site is in a random coil until the RNA binds, whereupon the 24 residues involved build a well-defined structure, thereby encapsulating the RNA.
  • (16) The latter increased again rapidly to rates above normal until antigen expression reached normal level, whereupon the protein synthesis rate decreased to normal.
