Although there are numerous examples of animals having photoreceptors sensitive to UVA (315-400 nm) [1] and relying on UVA-based mate-choice cues [2-5], here we provide the first evidence of an animal using UVB (280-315 nm) for intraspecific communication. An earlier study showed that Phintella vittata, a jumping spider (Salticidae) from China, reflects UVB [6]. By performing six series of bina...

Sr5Nb4O15 – Nb2O5 nanocomposites were synthesized in 2 and 4 M KOH aqueous solutions, via a non-stoichiometric 1:2 Sr:Nb molar ratio hydrothermal method at 160°C for 48 h (S1 and S2, respectively). Sr(NO3)2 and Nb2O5 were used as raw materials. The synthesized nanomaterials were characterized by powder X-Ray diffraction (PXRD) technique. It was found that Sr5Nb4O15 has been crystallized in hexa...

We described herein a concise synthesis of 3',4'-diaminoflavone 10. This new, three-step synthetic approach is more efficient than the conventional seven-step synthetic method. The route is shortened significantly by introducing the amino moieties early and eliminating the need for nitro group reduction. The other two analogues, 5,7-dihydroxy-3',4'-diaminoflavone 11 and 5,7-dimethoxy-3',4'-diam...

For the embryos and tadpoles of amphibian species, exposure to ultraviolet-B radiation (UVBR) can be lethal, or cause a variety of sublethal effects. Low temperatures enhance the detrimental effects of UVBR and this is most likely because the enzyme-mediated processes involved in the repair of UVBR-induced damage function less effectively at low temperatures. Whether these repair processes are ...

We measured chlorophyll (chl) concentration and chl a/b ratio in Sphagnum balticum, S. jensenii, and S. lindbergii, sampled after 7 and 8 years of ultraviolet-B (UVB) and temperature manipulation in an open field experiment in Finnish Lapland (68°N). We used plastic filters with different transmittance of UVB radiation to manipulate the environmental conditions. The plants were exposed to (1) a...

Background: Narrow band Ultraviolet B (NBUVB) has been used successfully for the treatment of vitiligo. Recently, topical calcipotriol has also been used as immunotherapy or as a part of combination therapies. The aim of this study was to compare the clinical efficacy and safety of NBUVB and NBUVB plus topical calcipotriol in the treatment of generalized vitiligo. Methods: NBUVB phototherapy wa...

Background. Psoralen plus ultraviolet A (PUVA) is the preferred phototherapeutic modality for early-stage folliculotropic mycosis fungoides (FMF), and non-FMF refractory to narrow-band B (NBUVB). However, PUVA has a problematic safety profile. Literature on treatment with combination of UVA NBUVB MF sparse. Objective. To evaluate effectiveness combined MF, specifically FMF NBUVB-refractory non-...
