List of MeSH codes (D23)

List of MeSH codes (D23) refers to a comprehensive categorization within the Medical Subject Headings (MeSH) system, specifically focusing on the D23 category. MeSH is a hierarchical vocabulary used for indexing, cataloging, and searching for biomedical and health-related information and documents. The D23 category encompasses a wide range of topics related to biological factors, biomedical and dental materials, chemical actions and uses, complex mixtures, hazardous or poisonous substances, and pharmaceutical preparations. This article provides an overview of the subcategories and specific codes within the D23 section of MeSH.

Biological Factors

Biological factors (MeSH code D23.050) include substances produced by living organisms that have effects on other organisms. These can range from hormones and enzymes to toxins and biomarkers. This category is crucial for understanding various physiological processes and disease mechanisms.

Biomedical and Dental Materials

The category for biomedical and dental materials (MeSH code D23.500) covers substances used in medical, dental, and surgical procedures. These materials include implants, prostheses, dental materials, and surgical equipment. Understanding the properties and applications of these materials is essential for clinical practice and biomedical engineering.

Chemical Actions and Uses

Chemical actions and uses (MeSH code D23.125) encompass the various effects and applications of chemicals in biological systems and medical treatments. This includes pharmacological actions, toxicological actions, and the use of chemicals in laboratory techniques and diagnostic procedures.

Complex Mixtures

Complex mixtures (MeSH code D23.250) refer to substances composed of many different components, such as biological products, fossil fuels, and waste products. The study of complex mixtures is important for environmental health, pharmacology, and toxicology.

Hazardous or Poisonous Substances

This category (MeSH code D23.946) includes substances that pose risks to health or the environment, such as toxins, poisons, carcinogens, and mutagens. Research and regulation of hazardous substances are critical for public health and safety.

Pharmaceutical Preparations

Pharmaceutical preparations (MeSH code D23.650) are substances formulated for medical treatment and prevention of diseases. This category covers a wide range of products, including drugs, vaccines, and nutritional supplements, and is central to pharmacology and therapeutics.

Conclusion

The List of MeSH codes (D23) provides a structured framework for organizing and accessing a vast array of information related to biological and chemical substances. By categorizing these substances based on their properties, uses, and effects, the MeSH system facilitates efficient retrieval of biomedical information, supporting research, clinical practice, and public health initiatives.
