概括
基于二氧化 (DHA) 的伪装对紫外线 (UV) 治疗结果具有临床上微不足道的影响. 大多数使用DHA伪装的白风患者不需要进行UV疗法剂量调整.
科学领域:
- 皮肤病学 皮肤病学
- 摄影生物学 摄影生物学
- 化品科学 化品科学
背景情况:
- Vitiligo 是一种常见的色素失调障碍,影响全球人口的0.5%-2%.
- 基于二亚 (DHA) 的伪装对紫外线 (UV) 治疗疗效的影响尚不清楚.
- 研究伪装效应对于优化白风治疗至关重要.
研究的目的:
- 为了评估3.6%的DHA伪装剂对紫外线引起的红血热的影响.
- 为了确定伪装是否需要调整紫外线治疗剂量.
- 为了评估伪装诱导的红血瘤变化的临床意义.
主要方法:
- 健康的志愿者 (皮肤类型III-IV) 接受了使用308nm紫外线灯的最低红斑剂量 (MED) 测试.
- 在皮肤上涂上3.6%的DHA伪装剂.
- 用视觉评估 (erMED) 和数字皮肤显微镜 (drMED) 来评估红斑,并测量红斑指数 (EI).
主要成果:
- 84.3%的受试者在伪装应用后没有改变MED.
- 在伪装和非伪装组之间观察到MED和EI的统计学上显著但临床上最小的差异.

Pigmentation
4.1K
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...

UV–Vis Spectroscopy of Conjugated Systems
8.2K
Organic compounds with conjugated double bonds show strong absorption features in the UV–visible region of the electromagnetic spectrum attributed to π → π* electronic excitations. Generally, a UV–vis absorption spectrum is recorded as a plot of absorbance vs wavelength. The wavelength of maximum absorbance, which manifests as a peak in the absorption spectrum, is denoted as λmax.
One of the factors influencing λmax is the extent of conjugation in...

UV–Vis Spectroscopy: Woodward–Fieser Rules
28.0K
UV–Visible absorption spectra of conjugated dienes arise from the lowest energy π → π* transitions. The light-absorbing part of the molecule is called the chromophore, and the substituents directly attached to the chromophore are called auxochromes. A strong correlation exists between the absorption maxima, λmax, and the structure of a conjugated π system. The Woodward–Fieser rules predict the value of λmax for a given structure by adding the...

Cycloaddition Reactions: MO Requirements for Photochemical Activation
2.6K
Some cycloaddition reactions are activated by heat, while others are initiated by light. For example, a [2 + 2] cycloaddition between two ethylene molecules occurs only in the presence of light. It is photochemically allowed but thermally forbidden.

UV–Vis Spectrum
1.9K
When light passes through a substance, a portion of the light is absorbed while the remaining light is reflected or transmitted. If the molecule absorbs light between the wavelengths of 180–400 nm range, the UV spectrum is obtained, and if it absorbs light in the 400–780 nm wavelength range, the visible spectrum is obtained.
The UV–Vis spectrum of a molecule is the plot of its absorbance versus wavelength. The plot is drawn by taking molar...
