Improving Translational Accuracy

14.9K
Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Uncertainty in Measurement: Accuracy and Precision

100.9K
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.

Standard Electrode Potentials

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...

Accuracy, limits, and approximation

1.3K
Accuracy, limits, and approximations are common in many fields, especially in engineering calculations. These concepts are imperative for ensuring that a given value is as close as possible to its true value.
Accuracy is defined as the closeness of the measured value to the true or actual value. In engineering mechanics, repeated measurements are taken during theoretical or experimental analyses to ensure that the result is precise and accurate.
The accuracy of any solution is based on the...

Area of Science:

  • Neurosurgery
  • Medical Robotics
  • Neurological Disorders

Background:

  • Deep brain stimulation (DBS) is a key treatment for Parkinson's disease.
  • Traditional awake DBS with microelectrode recording is time-consuming.
  • Asleep DBS utilizes imaging for electrode placement verification.

Purpose of the Study:

  • To demonstrate the validity of an asleep, robot-assisted DBS procedure.
  • To confirm precise electrode placement using intraoperative imaging.
  • To evaluate this technique in a large, inclusive patient cohort.

Main Methods:

  • Preoperative MRI for surgical planning in 128 patients.
  • Robot-assisted electrode implantation during surgery.
  • Intraoperative CT scans fused with preoperative MRIs for verification.

Main Results:

  • Mean radial error of electrode placement: 0.85 ± 0.38 mm.
  • MRI-CT fusion error: 0.64 ± 0.40 mm.
  • Average operating room times: 139.3 ± 34.7 min (bilateral), 115.4 ± 42.1 min (unilateral).

Conclusions:

  • The asleep robot-assisted DBS procedure is valid for accurate electrode placement.
  • Intraoperative CT verification ensures precision in asleep DBS.
  • This method offers shorter operating room times compared to traditional DBS.
