The Ability of Cyanobacterial Cells to Restore UV-B Radiation Induced Damage to Photosystem II is Influenced by Photolyase Dependent DNA Repair [PDF]

open access: yes, 2013
Damage of DNA and Photosystem-II are among the most significant effects of UV-B irradiation in photosynthetic organisms. Both damaged DNA and Photosystem-II can be repaired, which represent important defense mechanisms against detrimental UV-B effects ...

Sunscreens - Which and what for? [PDF]

open access: yes, 2005
It is well established that sun exposure is the main cause for the development of skin cancer. Chronic continuous UV radiation is believed to induce malignant melanoma, whereas intermittent high-dose UV exposure contributes to the occurrence of actinic ...

Intrinsic indicator of photodamage during label-free multiphoton microscopy of cells and tissues.

open access: yesPLoS ONE, 2014
Multiphoton imaging has evolved as an indispensable tool in cell biology and holds prospects for clinical applications. When addressing endogenous signals such as coherent anti-Stokes Raman scattering (CARS) or second harmonic generation, it requires ...

Characterization of patients with skin cancer and other affections caused by photodamage

open access: yesMedisan, 2022
Introduction: Photodamage is the aggression caused by solar radiation in the skin. In turn, the ultraviolet radiation is one of the first agents considered as cancer generators.

HSP27 Protects Skin From Ultraviolet B -Induced Photodamage by Regulating Autophagy and Reactive Oxygen Species Production

open access: yesFrontiers in Cell and Developmental Biology, 2022
Ultraviolet (UV) irradiation has been well documented to be linked with almost all skin problems we know, and both dermis and epidermis may be affected to varying degrees by UV irradiation. Every time when exposed to sunlight without protection, our skin

Photoprotection in ethnic skin

open access: yesDermatologica Sinica, 2014
Although cutaneous photodamage is partially mitigated by darker skin pigmentation, sun-induced aging, dyspigmentation, sunburns, and skin cancers are reported worldwide in all skin types and races.

Imiquimod Cream Improves Photodamaged Skin

open access: yesJournal of Dermatology and Dermatologic Surgery, 2022
Chronic exposure to ultraviolet light causes wrinkles and dyspigmentation. Imiquimod cream is an immune-modulator medication approved for the treatment of genital warts, actinic keratosis, and superficial basal cell carcinoma. Few scientific papers were published in the literature on the effect of imiquimod on photodamaged skin. We report four patients

Mechanism of Photodamage of the Oxygen Evolving Mn Cluster of Photosystem II by Excessive Light Energy

open access: yesScientific Reports, 2017
Photodamage to Photosystem II (PSII) has been attributed either to excessive excitation of photosynthetic pigments or by direct of light absorption by Mn4CaO5 cluster.
