Typical Model Studies

494
Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.

Induced-fit Model

Most chemical reactions in cells require enzymes—biological catalysts that speed up the reaction without being consumed or permanently changed. They reduce the activation energy needed to convert the reactants into products. Enzymes are proteins, that usually work by binding to a substrate—a reactant molecule that they act upon.
Enzymes exhibit substrate specificity, meaning that they can only bind to certain substrates. This is mainly determined by the shape and chemical...

Three-Compartment Open Model

547
The three-compartment open model is a pharmacokinetic model used to describe the distribution and elimination of drugs following extravascular administration. It comprises a central compartment representing the plasma and two peripheral compartments. The highly perfused peripheral compartment represents organs and tissues with a rich blood supply, such as the liver, kidneys, and lungs. The scarcely perfused peripheral compartment represents tissues with lower blood supply, such as adipose...

Clearance Models: Physiological Models

152
Drug clearance is a critical pharmacokinetic process involving the irreversible removal of drugs from the body through various organs over a specified time period. Physiological models are indispensable in determining organ-specific clearance, defined by the proportion of the drug eliminated per unit of time from the organ's blood volume.
The organ's clearance rate depends on the blood flow to the organ and the extraction ratio (E). The extraction ratio describes the organ's...

Clearance Models: Compartment Models

158
Clearance measures drug elimination from the central compartment, including plasma and highly perfused organs like kidneys and liver. Its calculation varies depending on pharmacokinetic models and administration routes. The one-compartment model, for instance, portrays the pharmacokinetics of polar drugs such as aminoglycoside antibiotics administered intravenously and readily excreted in urine. In this case, clearance is influenced by the terminal rate constant (λz) and the total volume...

Positron Emission Tomography01:29

Positron Emission Tomography

6.3K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Area of Science:

  • Endourology
  • Surgical Simulation
  • Medical Education

Background:

  • Percutaneous renal access (PCA) is a complex endourological procedure with a steep learning curve.
  • Effective surgical simulators are crucial for improving trainee skills, reducing complications, and shortening the learning curve.
  • Existing simulators may lack accessibility, realism, or affordability.

Discussion:

  • The TOMATO model offers a low-cost, easily reproducible, and realistic simulation for fluoroscopy-guided PCA training.
  • Utilizing common household items, the model effectively mimics renal anatomy without the need for contrast agents.
  • Participant feedback highlights the model's high-fidelity anatomical reproduction and effectiveness in teaching puncturing techniques.

Key Insights:

  • The TOMATO model significantly reduced kidney access time (KAT) and radiation time (RT) in novice trainees.
  • Residents demonstrated marked improvement in KAT and RT after training with the simulator.
  • Both trainees and experts rated the model highly for its anatomical fidelity and training utility.

Outlook:

  • The TOMATO model presents a promising, cost-effective solution for endourology training programs worldwide.
  • Further research could explore incorporating more complex anatomical variations or haptic feedback.
  • Widespread adoption of this simulator could enhance surgical proficiency and patient safety in PCA procedures.
