What is an Experiment?01:12

What is an Experiment?

18.9K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

Preclinical Development: Overview

6.0K
Preclinical development consists of a series of tests that ensure the safety and efficacy of a new therapeutic compound before it is tested in humans. There are four main phases to this process. First, safety pharmacology tests are conducted to ensure the drug does not produce any acutely harmful effects. These tests examine parameters such as bronchoconstriction, cardiac dysrhythmias, blood pressure changes, and ataxia. Next, preliminary toxicological testing is performed to determine the...

Thomson's e/m Experiment

6.9K
In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...

Controls in Experiments

17.7K
When conducting an experiment, it is crucial to have control to reduce bias and accurately measure the dependent variables. It also marks the results more reliable. Controls are elements in an experiment that have the same characteristics as the treatment groups but are not affected by the independent variable. By sorting these data into control and experimental conditions, the relationship between the dependent and independent variables can be drawn. A randomized experiment always includes a...

Randomized Experiments01:13

Randomized Experiments

9.1K
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Crossover Experiments01:16

Crossover Experiments

4.6K
Crossover experiments, also called the repeated-measurements design, is a study design in which all experimental units are exposed to all treatments in different periods. Crossover experiments are generally used in psychology, the pharmaceutical industry, agriculture, and medicine.
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.

Area of Science:

  • Biomedical Engineering
  • Surgical Robotics
  • Microsurgery

Background:

  • Robotic assistance can improve precision and dexterity in microsurgery.
  • A dedicated microsurgical robotic system, MicroSure, was developed.
  • This study evaluated the feasibility of robot-assisted microsurgical anastomosis on silicone vessels.

Purpose of the Study:

  • To investigate the successful completion of microsurgical anastomosis using the MicroSure robotic system.
  • To compare the outcomes of robot-assisted microsurgery with conventional microsurgery.

Main Methods:

  • Three participants performed 10 anastomoses manually and 10 with robotic assistance.
  • Microsurgical skill quality was assessed by four blinded experts using a modified Structured Assessment of Microsurgical Skills.
  • Anastomosis time and adverse events were recorded.

Main Results:

  • Robot-assisted anastomosis time was longer (35.1 minutes) compared to conventional (12.5 minutes).
  • Overall microsurgical skill scores improved with both methods, but were lower with robotic assistance initially.
  • Robot-assisted procedures showed steeper learning curves for both time and skill domains.

Conclusions:

  • The MicroSure robotic system is feasible for anastomotic microsurgery on silicone vessels.
  • Robot-assisted surgery was initially slower and resulted in lower skill quality compared to conventional methods.
  • Steeper learning curves suggest potential for future improvement and clinical application of the robotic system.
