Induced-fit Model01:13

Induced-fit Model

89.7K
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...

Inclusive Fitness

Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these altruistic behaviors evolved because they increase the inclusive fitness of the animal providing help.

Goodness-of-Fit Test

9.3K
The goodness-of-fit test is a type of hypothesis test which determines whether the data "fits" a particular distribution. For example, one may suspect that some anonymous data may fit a binomial distribution. A chi-square test (meaning the distribution for the hypothesis test is chi-square) can be used to determine if there is a fit. The null and alternative hypotheses may be written in sentences or stated as equations or inequalities. The test statistic for a goodness-of-fit test is given as...

Hybridoma Technology01:31

Hybridoma Technology

17.8K
Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.

Expected Frequencies in Goodness-of-Fit Tests01:19

Expected Frequencies in Goodness-of-Fit Tests

8.7K
A goodness-of-fit test is conducted to determine whether the observed frequency values are statistically similar to the frequencies expected for the dataset. Suppose the expected frequencies for a dataset are equal such as when predicting the frequency of any number appearing when casting a die. In that case, the expected frequency is the ratio of the total number of observations (n)  to the number of categories (k).

Area of Science:

  • Ophthalmology
  • Biomedical Engineering
  • Materials Science

Background:

  • Rigid gas permeable contact lenses (RGPCL) are crucial for correcting high refractive errors, keratoconus, and post-corneal transplantation.
  • Fitting RGPCL for patients with irregular corneas is challenging, often requiring multiple attempts.
  • Repeated fittings increase patient discomfort and risks like corneal epithelial shedding or infection.

Purpose of the Study:

  • To develop and evaluate a novel method for simulating RGPCL fitting using 3D printing technology.
  • To improve the efficiency and safety of the RGPCL fitting process for patients with irregular corneas.

Main Methods:

  • A new simulation method for RGPCL fitting was developed, leveraging 3D printing technology.
  • Preliminary experimental validation was conducted to assess the method's efficacy.

Main Results:

  • The 3D printing simulation method effectively reduced the number of RGPCL lens try-ons required.
  • Patient satisfaction was increased with the new simulation approach.
  • The method demonstrated a decrease in the risk of corneal epithelial shedding and infection.

Conclusions:

  • 3D printing simulation offers a faster and safer alternative for RGPCL fitting, especially for complex corneal cases.
  • This innovative approach enhances patient comfort and reduces potential complications.
  • Further research can optimize this technology for broader clinical application in contact lens fitting.
