Mutations

32.0K
Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.
Chromosomal Alterations Are Large-Scale Mutations
While point mutations are changes in a single nucleotide in...

Biological Effects of Radiation

15.0K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Area of Science:

  • Oncology
  • Gastroenterology
  • Radiation Medicine

Background:

  • Radiation therapy for abdominal and pelvic cancers can cause significant intestinal injuries.
  • These injuries complicate treatment and impact patient quality of life.
  • Current understanding of clinical aspects is limited.

Purpose of the Study:

  • To address the theoretical and clinical aspects of radiation-induced intestinal injuries.
  • To highlight the need for increased awareness among healthcare professionals and patients.
  • To emphasize the importance of developing personalized prevention and treatment strategies.

Main Methods:

  • Review of theoretical knowledge on radiation-induced intestinal injuries.
  • Analysis of clinical manifestations and complications.
  • Discussion of current gaps in understanding and management.

Main Results:

  • Radiation-induced intestinal injuries are a common yet often underestimated complication.
  • Lack of awareness contributes to diagnostic and therapeutic challenges.
  • Existing approaches to prevention and treatment require further refinement.

Conclusions:

  • Radiation-induced intestinal injuries necessitate greater clinical attention.
  • Personalized medicine approaches are essential for effective management.
  • Further research is vital to improve patient care in internal medicine.
