Development of Analytical Methods01:21

Development of Analytical Methods

3.1K
An analytical methodology can be divided into four sequential steps: technique, method, procedure, and protocol. A technique is a scientific principle that rationalizes a specific phenomenon through chemical measurements. Adapting a technique for analyzing a sample of interest is termed a method. The procedure outlines the directions for performing the analysis via an analytical method. The protocol is the detailed guidelines on the procedure, which should be strictly followed to obtain the...

Qualitative Analysis

1.9K
Qualitative analysis is the process of identifying elements, ions, or compounds in an unknown sample. It is the first and most fundamental type of analysis based on the hierarchy of analytical goals. This hierarchy is significant as it provides a structured approach to scientific research, with qualitative analysis serving as the initial step, providing essential information before moving on to quantitative or other forms of analysis.
There are two main approaches to qualitative analysis:...

Mechanistic Models: Compartment Models in Algorithms for Numerical Problem Solving

397
Mechanistic models play a crucial role in algorithms for numerical problem-solving, particularly in nonlinear mixed effects modeling (NMEM). These models aim to minimize specific objective functions by evaluating various parameter estimates, leading to the development of systematic algorithms. In some cases, linearization techniques approximate the model using linear equations.
In individual population analyses, different algorithms are employed, such as Cauchy's method, which uses a...

The Scientific Method03:50

The Scientific Method

71.6K
Chemistry is an empirical science. Scientists often pose questions to understand the chemistry in everyday life and seek answers to these questions. To achieve this, scientists follow a definitive series of steps that together make up the Scientific Method. This approach involves making observations, asking questions, building a hypothesis, conducting experiments, analyzing results, and forming a conclusion.

Mechanistic Models: Compartment Models in Individual and Population Analysis

321
Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

One-Compartment Open Model: Wagner-Nelson and Loo Riegelman Method for ka Estimation

1.4K
This lesson introduces two critical methods in pharmacokinetics, the Wagner-Nelson and Loo-Riegelman methods, used for estimating the absorption rate constant (ka) for drugs administered via non-intravenous routes. The Wagner-Nelson method relates ka to the plasma concentration derived from the slope of a semilog percent unabsorbed time plot. However, it is limited to drugs with one-compartment kinetics and can be impacted by factors like gastrointestinal motility or enzymatic degradation.

Area of Science:

  • Medical Informatics
  • Ontology Engineering
  • Health Services Research

Background:

  • The Austrian Procedure Catalogue (APC) is a country-specific system for coding medical procedures.
  • Existing APC has limitations in usability, especially for research and e-health applications, due to a lack of formal definitions and poor classification.
  • There is a need for standardized, semantically enriched health intervention coding systems.

Purpose of the Study:

  • To develop an ontologized version of the Austrian Procedure Catalogue (APC) to improve its usability.
  • To present a novel four-step ontology engineering approach for formalizing health intervention coding systems.
  • To extract and define key concepts and relationships for medical ontologies from textual data.

Main Methods:

  • A four-step approach was employed: comparative pre-analysis, definition analysis, typological analysis, and ontology implementation.
  • Comparative pre-analysis involved evaluating the APC against other health intervention coding systems.
  • Definition and typological analyses, adapted from social sciences, were used to identify core characteristics of health interventions.

Main Results:

  • The APC's shortcomings, including implicit information and inadequate procedural type classification, were identified.
  • Eleven main characteristics of health interventions were defined: Procedural type, Anatomical site, Medical device, Pathology, Access, Body system, Population, Aim, Discipline, Technique, and Body Function.
  • Relevant classes and relationships for formalizing the APC were identified.

Conclusions:

  • The proposed four-step approach offers a robust framework for semantically enriching procedure classifications.
  • The methodology is adaptable and can be applied to other procedure catalogs, promoting universal alignment.
  • This work contributes to the development of more usable and interoperable health intervention coding systems.
