Cellular and Genetic Bases of Cold Nociception and Nociceptive Sensitization In Drosophila Larvae
… suffering from tissue damage (from wound or sunburn), or injury to the peripheral nerves, as in patients with diabetes or undergoing chemotherapy. Our goal is to determine the genetic basis for noxious cold perception and injury-induced nociceptive sensitization using the genetically …

Attitudes and Behaviors of Adolescents toward Sunbathing and Sunscreen Use.
… use sunscreen yet to report higher incidence of sunburns. Those with a healthy lifestyle attitude are as likely to engage in intentional tanning, although they are more likely to wear sunscreen. Self-report of tanning behavior was positively correlated to parent's observation of adolescent's …

Damage-Induced Inflammation and Nociceptive Hypersensitivity In Drosophila Larvae
… pain hypersensitivity, we developed a “sunburn assay” and found that larvae have a lowered pain threshold (allodynia) and an exaggerated response to noxious stimuli (hyperalgesia) following UV damage. We screened for genes required for hypersensitivity in pain receptors (nociceptors), …

Comparison of quality of life and health behaviors between melanoma survivors and controls
… controls, a significant subgroup experienced sunburn in the past year, putting them at elevated risk for future melanomas. The data presented in this dissertation suggest that long-term melanoma survivors reported similar quality of life as controls, though opportunities exist to improve their …

“An American Sun Shines Brighter”: Art, Science, and the American Reinvention of Photography
… present, I offer a coda examining Chris McCaw’s Sunburn series, which I suggest illustrates how the medium’s chemical and artisanal past has come to serve a renewed aesthetics of fine art photography in the twenty-first century.</p>

Refining Fruit-Zone Leaf Removal for Red-Fruited Bordeaux Grape Varieties Grown in a Humid Environment
… after fruit set to limit fungal disease and sunburn incidence, and prevent extreme heating of grapes. The goal of this work was to assess if fruit-zone leaf removal to an uncommonly greater extent, and/or at an earlier phenological stage, would favorably alter yield components or fruit …

Anti-aging potential of some freshwater microalgae extracts
… vessels, epidermal hyper proliferation, and sunburn. Existing skincare products for anti-aging are known to include hazardous substances associated with an elevated skin cancer risk. As a result, there is a need to look for natural alternative cosmetic items. Thus, this study aimed to assess …

The role of eicosanoids in the human skin's response to ultraviolet radiation.
… in SPT-4 skin may aid resolution of the sunburn response, which in part may be mediated by CD3+ lymphocytes and a class-switch in eicosanoid production from COX to LOX products. Melanocyte primary cultures surprisingly showed that SPT was not correlated with melanin content or melanogenic …

Ultrastructural characterization of ultraviolet induced corneal disease : an animal model
… radiation in the solar spectrum which cause sunburn. We now recognize that the small portion of ultraviolet radiation which reaches the earth's surface is not necessarily therapeutic, but in fact could be harmful to humans. There are numerous accounts of the harmful effects of UV radiation to …

Targeting mutant p53 in cSCCs
… prevent cSCC development and induce tanning and sunburn responses in skin cells. However, TP53 mutations are found in over half of all human cancers and cSCC is no exception as TP53 mutational frequency in cSCCs is around 64-87.5% (Durinck et al, 2011; South et al, 2014). The majority of TP53 …

The Effects of Perspiration Application, Weathering Exposures, Washing Action of Automatic Home Clothes Washers, and Repeated Laundering on the Ultraviolet Protection of a Naturally Colored Lightweight Cotton Fabric
… in harmful effects on human skin, including sunburn, premature skin ageing, and in the worst case, skin cancer (Eckhardt and Rohwer, 2000; Sengupta and Blain, 2001). The diminishing stratospheric ozone layer, due to environmental degradation in the past few decades, combined with the modern …
