A Randomized Comparison of Selective Broadband UVB and Narrowband UVB in the Treatment of Psoriasis [PDF]
Journal of Investigative Dermatology, 2007 UVB is widely used to treat psoriasis. Conventional broadband UVB lamps are less effective than narrowband UVB lamps, which have an emission peak at 311 nm. The long-term safety of narrowband UVB phototherapy is uncertain. "Selective" broadband UVB lamps, which have little emission

UVB: suscetibilidade no melanoma maligno UVB: susceptibility in malignant melanoma [PDF]
Anais Brasileiros de Dermatologia, 2010 FUNDAMENTOS: Está bem definido que a radiação ultravioleta provoca depleção imunológica na pele, permitindo o desenvolvimento de tumores cutâneos malignos. A maioria dos pacientes de cânceres da pele não melanomas são considerados UVB-suscetíveis. OBJETIVOS: Estudar a UVB-suscetibilidade nos pacientes com melanoma maligno e se este é um fator de risco ...

Characterisation of apoptotic responses in human keratinocytes expressnig alpha-6 integrin and CD44 [PDF]
, 2010 PhDa6 integrin has previously been proposed as a human keratinocyte stem cell markers. CD44-positive cells in epithelial tumours have been identified as potential cancer stem cells (CSCs) and display increased survival following chemotherapy ...

Protective effects of Centella asiatica leaf extract cream on IL-1a expression and sunburn cells in BALB/c mice induced by UVB [PDF]
Scripta MedicaBackground/Aim: UVB radiation can induce DNA damage in keratinocyte cells, leading to increased levels of reactive oxygen species (ROS) triggered by the release of proinflammatory cytokine IL-1a and apoptosis (sunburn) of keratinocyte cells.

Irradiance-dependent UVB Photocarcinogenesis [PDF]
Scientific Reports, 2016 AbstractUltraviolet B (UVB) radiation from the sun may lead to photocarcinogenesis of the skin. Sunscreens were used to protect the skin by reducing UVB irradiance, but sunscreen use did not reduce sunburn episodes. It was shown that UVB-induced erythema depends on surface exposure but not irradiance of UVB. We previously showed that irradiance plays a

Riboflavin in photodynamic inactivation of pathogens and photodynamic therapy [PDF]
Annals of Mechnikov's Institute, 2020 Riboflavin, besides its key role in providing cellular metabolism in humans and animals, is used as a compound of antimicrobial photodynamic therapy (aPDT) owing to its photosensitizing capability. PDT is a promising approach for the photoinactivation of

Jujube and green tea extracts protect human fibroblast cells against UVB-mediated photo damage and MMP-2 and MMP-9 production [PDF]
Avicenna Journal of Phytomedicine, 2020 Objective: Oxidative stress and ultraviolet B (UVB) irradiation are known as principal inducers of DNA damage and modulators of gene expression in aging process and skin photoaging, which are associated with upregulation of matrix metalloproteinases ...
