Mutations01:35

Mutations

46.7K
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...

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview01:02

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview

8.7K
Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material,  molecules absorb light depending on the energy required for...

UV–Vis Spectrometers01:14

UV–Vis Spectrometers

4.7K
The absorbance of UV and visible (UV–visible) radiations is measured using a UV–visible spectrophotometer. Deuterium lamps, which emit UV radiation, and tungsten lamps, which produce radiation in the visible region, are used as light sources in UV–visible spectrophotometers. A monochromator or prism is used for diffraction grating, i.e., to split the incoming radiation into different wavelengths. A system of slits is used to focus the desired wavelength on the sample cell.

Biological Effects of Radiation02:59

Biological Effects of Radiation

19.9K
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...

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:

  • Dermatology
  • Photomedicine
  • Radiation Biology

Background:

  • Ultraviolet radiation (UVR) is a recognized treatment for chronic skin conditions.
  • However, UVR exposure can damage DNA and cause side effects, including erythema and carcinogenesis.
  • Chronic conditions require repeated, high-dose UVR exposure, increasing risks.

Purpose of the Study:

  • To review the current state of UVR phototherapy.
  • To highlight the underdeveloped area of quantitative UVR dosimetry.
  • To emphasize the need for improved dosimetry to optimize treatment and minimize adverse effects.

Main Methods:

  • Review of existing literature on UVR phototherapy.
  • Overview of UVR production, biological effects, and illnesses treated.
  • Examination of cabin design, clinical implementation, and dose estimation techniques.
  • Analysis of current dose models for UVR phototherapy.

Main Results:

  • UVR phototherapy is effective but carries risks due to DNA damage and side effects.
  • Quantitative dosimetry for UVR phototherapy is underdeveloped.
  • Existing dose models are insufficient for accurate clinical dose estimation.

Conclusions:

  • Accurate computational dose estimation methods are needed for UVR phototherapy.
  • Improved dosimetry will enable clinicians to balance therapeutic effects with risks of overexposure.
  • Further research into UVR dosimetry is essential for safer and more effective phototherapy.
