Photobiology is the scientific study of the beneficial and harmful interactions of light in living organisms. The field includes the study of photophysics, photochemistry, photosynthesis, photomorphogenesis, visual processing, circadian rhythms, photomovement, bioluminescence, and ultraviolet radiation effects.
Blepharisma is a genus of unicellular ciliate protists found in fresh and salt water. The group includes about 40 accepted species, and many sub-varieties and strains. While species vary considerably in size and shape, most are easily identified by their red or pinkish color, which is caused by granules of the pigment blepharismin.
Avobenzone is an organic molecule and an oil-soluble ingredient used in sunscreen products to absorb the full spectrum of UVA rays.
Octyl methoxycinnamate or ethylhexyl methoxycinnamate (INCI) or octinoxate (USAN), trade names Eusolex 2292 and Uvinul MC80, is an organic compound that is an ingredient in some sunscreens and lip balms. It is an ester formed from methoxycinnamic acid and 2-ethylhexanol. It is a liquid that is insoluble in water.
Autofluorescence is the natural emission of light by biological structures such as mitochondria and lysosomes when they have absorbed light, and is used to distinguish the light originating from artificially added fluorescent markers (fluorophores).
Photoprotection is the biochemical process that helps organisms cope with molecular damage caused by sunlight. Plants and other oxygenic phototrophs have developed a suite of photoprotective mechanisms to prevent photoinhibition and oxidative stress caused by excess or fluctuating light conditions. Humans and other animals have also developed photoprotective mechanisms to avoid UV photodamage to the skin, prevent DNA damage, and minimize the downstream effects of oxidative stress.
Photochemical & Photobiological Sciences is a monthly peer-reviewed scientific journal covering all areas of photochemistry and photobiology. It was established in 2002 and is published by Springer Science+Business Media on behalf of the European Photochemistry Association and the European Society for Photobiology. The editors-in-chief are Dario Bassani and Rex Tyrrell.
Previtamin D3 is an intermediate in the production of cholecalciferol (vitamin D3).
Serine/threonine-protein phosphatase 5 is an enzyme that in humans is encoded by the PPP5C gene.
Minjoong Yoon is a South Korean chemist and professor.
Genes to Cells is a peer-reviewed scientific journal that publishes original research on the molecular mechanisms of biological events. The journal has been published since 1996 by Wiley-Blackwell on behalf of the Molecular Biology Society of Japan.
Hematoporphyrin is a porphyrin prepared from hemin. It is a derivative of protoporphyrin IX, where the two vinyl groups have been hydrated. It is a deeply colored solid that is usually encountered as a solution. Its chemical structure was determined in 1900.
The American Journal of Transplantation is a monthly peer-reviewed medical journal published by Elsevier on behalf of the American Society of Transplant Surgeons and the American Society of Transplantation. It covers research on all aspects of organ transplantation. Each issue offers continuing medical education in the form of its Images in Transplantation feature, a case-based approach.
The American Society for Photobiology (ASP) is a scientific society for the promotion of research in photobiology, integration of different photobiology disciplines, dissemination of photobiology knowledge, and provides information on photobiological aspects of national and international issues.
The Journal of Photochemistry and Photobiology is a series of peer-reviewed scientific journals covering the fields of photochemistry and photobiology, published by Elsevier. It was originally established in 1972, and split into Journal of Photochemistry and Photobiology A: Chemistry and Journal of Photochemistry and Photobiology B: Biology in 1987. A third title; Journal of Photochemistry and Photobiology C: Photochemistry Reviews, was established in 2000 and is the official journal of the Japanese Photochemistry Association.
Photodermatology, Photoimmunology and Photomedicine is a peer-reviewed scientific journal published bimonthly by Wiley-Blackwell which focusses, as its title implies, on photodermatology, photoimmunology and photomedicine. Warwick L. Morison is editor-in-chief. It is the official journal of the Photomedicine Society, the British Photodermatology Group, and the European Society for Photodermatology.
Angelicin is the parent compound in a family of naturally occurring organic compounds known as the angular furanocoumarins. Structurally, it can be considered as benzapyra-2-one fused with a furan moiety in the 7,8-position. Angelicin is commonly found in certain Apiaceae and Fabaceae plant species such as Bituminaria bituminosa. It has a skin permeability coefficient (LogKp) of -2.46. The maximum absorption is observed at 300 nm. The 1HNMR spectrum is available; the infrared and mass spectra of angelicin can be found in this database. The sublimation of angelicin occurs at 120 °C and the pressure of 0.13 Pa. Angelicin is a coumarin.
The Journal of Biological Rhythms is a bimonthly peer-reviewed scientific journal that covers chronobiology or any rhythms, especially biological rhythms with a special emphasis on seasonal and circadian rhythms. The journal publishes primary reports, reviews, commentaries, or letters. The Journal of Biological Rhythms has been in publication since 1986 and is currently published by SAGE Publications. The journal is the official publication of the Society for Research on Biological Rhythms. The editor-in-chief is William J. Schwartz.
The Journal of Antimicrobial Chemotherapy is a peer-reviewed medical journal which covers antimicrobial chemotherapy, including laboratory aspects and clinical use of antimicrobial agents. It is published by Oxford University Press on behalf of the British Society for Antimicrobial Chemotherapy and was established in 1975. In January 2015 J. Peter Donnelly became the eighth editor-in-chief replacing Alan P. Johnson. The journal has had two previous publishers. All content is available for free after 12 months while authors also have the option to have their articles published immediately as open access.
Howard Harold Seliger was a physicist, biochemist, and biology professor, known for his research on bioluminescence.
