What is an Experiment?

19.2K
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...

Thomson's e/m Experiment

7.0K
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

18.5K
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 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 Experiments

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.

    Summary

    Laparoscopic cervical cerclage before pregnancy is a safe procedure with no reported complications in 7 women. This method offers a viable option for cervical support during pregnancy.

    Area of Science:

    • Reproductive Medicine
    • Minimally Invasive Surgery

    Background:

    • Cervical insufficiency is a condition that can lead to premature birth.
    • Cervical cerclage is a surgical procedure to prevent premature birth by reinforcing the cervix.
    • Various methods exist, including vaginal, abdominal, and laparoscopic approaches.

    Purpose of the Study:

    • To evaluate the safety and efficacy of pre-pregnancy laparoscopic cervical cerclage.
    • To discuss the indications and techniques for different types of cervical cerclage.

    Main Methods:

    • Retrospective review of 7 women who underwent pre-pregnancy laparoscopic cervical cerclage.
    • Analysis of intraoperative and postoperative outcomes.
    • Comparison of laparoscopic cerclage with vaginal and abdominal cerclage techniques.

    Main Results:

    • No intraoperative or postoperative complications were observed in the 7 women.
    • Laparoscopic cervical cerclage was successfully performed before pregnancy.
    • The study discusses the advantages and disadvantages of each cerclage method.

    Conclusions:

    • Pre-pregnancy laparoscopic cervical cerclage appears to be a safe and effective procedure.
    • Laparoscopic cervical cerclage offers a minimally invasive option for cervical support.
    • Further research is warranted to compare outcomes with other cerclage methods.
