Screening by coral green fluorescent protein (GFP)-like chromoproteins supports a role in photoprotection of zooxanthellae

, 2013
Green fluorescent protein (GFP)-like pigments are responsible for the vivid colouration of many reef-building corals and have been proposed to act as photoprotectants.

From fundamental science to product : a bottom-up approach to sunscreen development [PDF]

, 2018
Despite the pivotal role of ultraviolet (UV) radiation in sustaining life on Earth, overexposure to this type of radiation can have catastrophic effects, such as skin cancer. Sunscreens, the most common form of artificial protection against such harmful

Comparative Molecular Insights into Developmental and Behavioral Toxicity Induced by Octocrylene and Ethylhexyl Salicylate Exposure on Zebrafish

Integrative Zoology, EarlyView.
This study compared the ecological toxicity of organic ultraviolet filters, octocrylene (OC) and ethylhexyl salicylate (EHS), on zebrafish embryos and larvae. EHS exhibited higher acute toxicity, causing increased mortality, hypoactive behavior at 50 mg/L, and disruptions in lipid homeostasis, while OC primarily affected hypoxia response and ...

Improving photosynthesis and crop productivity by accelerating recovery from photoprotection [PDF]

, 2016
Crop leaves in full sunlight dissipate damaging excess absorbed light energy as heat. When sunlit leaves are shaded by clouds or other leaves, this protective dissipation continues for many minutes and reduces photosynthesis. Calculations have shown that

Low Sunscreen Awareness and Misconceptions in Skin of Colour With Acne‐Related Post‐Inflammatory Hyperpigmentation: A Cross‐Sectional Study Highlighting the Need for Targeted Education

Australasian Journal of Dermatology, EarlyView.
ABSTRACT Background/Objectives Post‐inflammatory hyperpigmentation (PIH) is a frequent sequela of acne in patients with skin of colour (SOC). While sunscreen is widely recommended for PIH prevention, little is known about real‐world sunscreen practices in this group. This study aimed to evaluate sunscreen use, barriers and factors influencing adherence

Origin and evolution of water oxidation before the last common ancestor of the Cyanobacteria [PDF]

, 2015
Photosystem II, the water oxidizing enzyme, altered the course of evolution by filling the atmosphere with oxygen. Here, we reconstruct the origin and evolution of water oxidation at an unprecedented level of detail by studying the phylogeny of all D1 ...

A Narrative Review of the Factors Impacting Solid Organ Transplant Recipient Participation in Skin Cancer Screening

Australasian Journal of Dermatology, EarlyView.
ABSTRACT Solid organ transplant recipients (SOTRs) are at a significantly elevated risk of cutaneous malignancy due to the requirement for lifelong immunosuppressive medications. Regular full skin examinations (FSEs) with a specialist clinician are recommended by most guidelines and are critical for early skin cancer detection.

Photoprotection in intact cells of photosynthetic bacteria: quenching of bacteriochlorophyll fluorescence by carotenoid triplets. [PDF]

, 2017
Upon high light excitation in photosynthetic bacteria, various triplet states of pigments can accumulate leading to harmful effects. Here, the generation and lifetime of flash-induced carotenoid triplets (3Car) have been studied by observation of the ...
