Mutations01:35

Mutations

38.2K
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

2.8K
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

1.4K
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.

Pigmentation01:19

Pigmentation

2.5K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Area of Science:

  • Dermatology
  • Imaging Technology
  • Public Health

Background:

  • Ultraviolet (UV) photography utilizes UV-transmitting filters to visualize UV-blocking substances like sunscreens.
  • Assessing the adequate coverage of sun protection lotions is crucial for effective photoprotection.

Purpose of the Study:

  • To evaluate commercially available UV photography cameras as tools for visualizing sunscreen coverage.
  • To determine the efficacy of UV photography in assessing the application of various sun protection products.

Main Methods:

  • The study involved three phases: testing three UV cameras, assessing UV photography's utility with diverse sunscreens, and developing/field-testing a UV webcam.
  • Participants applied sun protection products (SPF 15-50+), and UV photographs were taken to evaluate coverage and retention over time.
  • A portable UV webcam was developed and deployed at a public beach for user interaction and feedback.

Main Results:

  • UV camera systems accurately identified the application of sunscreens (SPF 15-50+), with adequate sensitivity to detect coverage at different concentrations.
  • Participants reported high satisfaction with UV photography, with 83% expressing likelihood to use it in the future.
  • While effective for many products, UV photography had limitations in visualizing coverage for certain tinted sunscreens. The UV webcam was used 233 times during field testing.

Conclusions:

  • UV photography is a viable tool for identifying areas missed during sunscreen application, particularly for products with chemical filters.
  • The technology offers potential for personalized feedback, enhancing user engagement and promoting more effective sun protection practices.
