Advances in organic UV filters for sunscreens over the past decade

Photochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Methods for substituting onsite ambient ultraviolet radiation measurements for personal exposure studies

Photochemistry and Photobiology, EarlyView.
Three methods for substituting on‐site ambient ultraviolet radiation measurements for personal exposure measurements were investigated. Assuming spatial persistency of measurements from high‐grade instruments delivers lowest uncertainties up to distances of 82 km.

Structure-activity relationships of flavonoids in the protection of UVB-induced damage

, 2011
碩士本論文利用斑馬魚進行活體毒性及抗氧化能力測試，作為篩選黃酮衍生物防護UVB能力的平台。首先，以100 mJ/cm2的UVB照射三天大的斑馬魚幼魚，每半小時照射一次共六次，發現最易觀察鰭傷害的變化是腹鰭。再加入一系列黃酮衍生物預防UVB所造成的傷害，以生物存活統計分析其毒性，並以抗氧化能力測試比較其防護UVB的能力，發現morin跟chrysin具有良好防護UVB的效果。進一步藉由理論與實驗結合的藥物開發方法—定量結構活性關係（Quantitative Structure-Activity ...

Cis‐urocanic acid formation following far‐UVC exposure and associated signaling responses in keratinocytes

Photochemistry and Photobiology, EarlyView.
Far‐UVC (200–235 nm) has emerged as a safe and effective indoor disinfection tool, but effects on skin immunomodulation remain unclear. This study demonstrates that 222 nm far‐UVC converts trans‐urocanic acid (UCA) to its biologically active cis isomer at levels comparable with solar radiation. In keratinocytes, far‐UVC alone caused modest increases in

Development of chalcones structure‐related to avobenzone: Photoprotection, photostability, and safety evaluation

Photochemistry and Photobiology, EarlyView.
Scaffold hopping strategy used to develop chalcones structure‐related to the avobenzone tautomer. Positive aspects of 2‐hydroxychalcones are highlighted. Abstract Chalcones are α,β‐unsaturated ketones with extended π‐conjugation, making them promising scaffolds for the development of organic UV filters.

Vitiligoda dar uvb, kalsipotriol-dar band uvb, betametazon-kalsipotriol-dar band uvb kombinasyon tedavilerinin etkinliğinin karşılaştırılması

, 2021
Background: Vitiligo is an idiopathic, acquired, well-demarcated disorder characterized by depigmented macules. There are clinical variants of localized, generalized, universal and mixed types. Photochemotherapy is the most commonly used treatment modality in generalized vitiligo.
