Lewis Symbols and the Octet Rule02:36

Lewis Symbols and the Octet Rule

80.4K
Chemical bonds are complex interactions between two or more atoms or ions, which reduce the potential energy of the molecule. Gilbert N. Lewis developed a model called the Lewis model that simplified the depiction of chemical bond formation and provided straightforward explanations for the chemical bonds seen in most common compounds.

The Aufbau Principle and Hund's Rule

72.4K
To determine the electron configuration for any particular atom, we can build the structures in the order of atomic numbers. Beginning with hydrogen, and continuing across the periods of the periodic table, we add one proton at a time to the nucleus and one electron to the proper subshell until we have described the electron configurations of all the elements. This procedure is called the aufbau principle, from the German word aufbau (“to build up”). Each added electron occupies the...

Fundamental Mathematical Principles in Pharmacokinetics: Mathematical Expressions and Units

1.5K
Mathematical principles play a crucial role in pharmacokinetics, providing a framework for understanding and quantifying drug distribution and elimination dynamics in the body. By utilizing mathematical expressions and units, pharmacologists can accurately characterize the behavior of drugs, optimize dosing regimens, and predict therapeutic outcomes.
One significant application of mathematics in pharmacokinetics is the characterization of drug distribution through the volume of distribution...

Histone Modification02:32

Histone Modification

16.0K
The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.
Acetylation
The enzyme histone acetyltransferase adds acetyl group to the histones. Another enzyme, histone...

The Quotient Rule01:30

The Quotient Rule

49
The quotient rule is a fundamental differentiation technique in calculus used to differentiate functions expressed as a ratio of two differentiable functions. Given a function of the form:Where g(x) and h(x) are both differentiable and h(x) ≠ 0, the derivative of f(x) is given by:Example:The quotient rule is beneficial when differentiating rational functions, trigonometric ratios, and exponential functions. For example, given:applying the quotient rule,This rule is essential in solving...

Area of Science:

  • Pharmacology
  • Medical Informatics
  • Computational Biology

Background:

  • Pediatric medication dosing is complex and prone to errors, potentially harming patients.
  • Current computer-assisted dosing systems can generate excessive, non-actionable alerts (alert fatigue).
  • Optimizing clinical decision support (CDS) dosing rules is crucial for patient safety.

Purpose of the Study:

  • To evaluate the feasibility of a novel mathematical model and algorithm for adjusting electronic medication dosing rules.
  • To improve computer-assisted dosing by reducing spurious alerts and optimizing dosing parameters.
  • To enhance the accuracy and efficiency of pediatric medication dosing.

Main Methods:

  • Developed a mathematical model and algorithm using historical ordering data to automatically determine optimal dosing rule parameters.
  • Optimized dosing rules by balancing alert generation with minimal dose intervals.
  • Tested the algorithm on 5 candidate medications and compared alert rates with existing rules.

Main Results:

  • The algorithm generated clinically relevant dosing rule possibilities for tested medications.
  • The new rules performed comparably to or better than current rules in reducing the overall alert burden.
  • The algorithm's output matched historical prescriber behavior, indicating clinical appropriateness.

Conclusions:

  • The mathematical model and algorithm offer an accurate, scalable solution for adjusting medication dosing rules.
  • This automated approach can expedite the correction of suboptimal dosing rules compared to manual methods.
  • The system can help identify and rectify poor-quality dosing rules, reducing alert fatigue and medication errors.
