Article Title: Ultraviolet Fluorescence Photography—Choosing the Correct Filters for Imaging
Article Snippet: The Zeiss T* UV had slightly lower fluorescence than the Schott KV-418, possessed good UV blocking, had a similar cutoff wavelength but reached 50% maximum transmission at a slightly shorter wavelength, had greater maximum transmission, is available in different sizes, and most importantly, is currently commercially available.

Article Title: Ultraviolet Fluorescence Photography—Choosing the Correct Filters for Imaging
Article Snippet: Some filters, such as the Schott GG400 and GG420; the Quaser 415 nm, 476 nm and 510 nm; the Heliopan Yellow 5; and Hoya Yellow Y(K2), exhibited extremely strong fluorescence under UV light, while others, such as Schott KV-418, Baader UV/IR cut, Tiffen Yellow 12, the RG series IR filters, Firecrest UV400 and Zeiss T* UV, showed very little if any visible fluorescence.

Article Title: Ultraviolet Fluorescence Photography—Choosing the Correct Filters for Imaging
Article Snippet: Of the commercially available camera filters that were tested here, the Zeiss T* UV filter was the closest to the Schott KV-418, as it started to transmit at a similar wavelength (at around 405 nm), although its transmission did rise faster than the Schott KV-418, reaching 50% at around 411 nm vs. 418 nm for the Schott KV-418.

Article Title: Ultraviolet Fluorescence Photography—Choosing the Correct Filters for Imaging
Article Snippet: In the Schott KV-418, this central layer is pale yellow.

Article Title: Ultraviolet Fluorescence Photography—Choosing the Correct Filters for Imaging
Article Snippet: Tiffen Yellow 8 had greater fluorescence than Schott KV-418 and also had a leak in the UV part of transmission spectra and would therefore not be recommended.

Article Title: Ultraviolet Fluorescence Photography—Choosing the Correct Filters for Imaging
Article Snippet: Both versions showed lower fluorescence than the Schott KV-418 filter; however, one version of it had twice the level of fluorescence of the other version, highlighting the need for the researcher to be able to determine how their own filters behave when designing an imaging system.

Article Title: Ultraviolet Fluorescence Photography—Choosing the Correct Filters for Imaging
Article Snippet: The Baader UV/IR had a very similar wavelength for 50% transmission to the Schott KV-418 and GG420 and, like the Zeiss T* UV filter, also exhibited very low fluorescence under UV light.

Article Title: Membrane lipid organization and nicotinic acetylcholine receptor function: A two-way physiological relationship.
Article Snippet: Nicotinic acetylcholine receptors (nAChRs) are involved in a great range of physiological and pathological conditions.. Since they are transmembrane proteins, they interact strongly with the lipids surrounding them.. Thus, the plasma membrane composition and heterogeneity play an essential role for the correct nAChR function, on the one hand, and the nAChR influences its immediate lipid environment, on the other hand.
