The mechanisms by which different light spectra regulate plant shoot elongation vary, and phytohormones respond differently to such spectrum-associated regulatory effects. Light supplementation can effectively control seedling growth in Norway spruce. However, knowledge of the effective spectrum for promoting growth and phytohormone metabolism in this species is lacking. In this study, 3-year-o...

Blue cheeses are those whose matrix is veined with a blue, blue-grey, or blue-green colour due to the development of Penicillium roqueforti. There more than 45 varieties blue cheese produced worldwide, some distinct features, although manufacture process similar. In addition P. roqueforti, complex microbial populations interact and succeed throughout manufacturing ripening at cheese’s surface (...

A soluble viral antigen with possible diagnostic utility was obtained from blue-tongue virus-infected lamb kidney cells. It is a noninfectious proteinaceous substance without nucleic acid. The antigen is immunologically identical to one component of the viral particle, and in agar-gel diffusion tests it reacted with antiserum against several blue-tongue virus strains.

Electrostatic interactions between an ESIPT molecule 2-(5'-amino-2'-hydroxyphenyl)benzothiazole (AHBT) and a phenylborate derivative give blue-green emission in acetic acid solution, but interestingly, vigorous (or mechanical) shaking of the solution leads to the formation of organic AHBT nanoparticles, which results in fluorescence colour switching from blue-green to yellow-orange.

Irradiation of the gametophytes of Pteridium aquilinum with blue light led to a nearly 5-fold increase in the amino acid-incorporating activity of isolated chloroplasts. The blue light effect was not due to increased synthesis of ATP or other energy donors by the chloroplasts but was probably related to an increased production of chlorophyll and photosynthetic enzymes.

entire lesion was fixed in Bouin's fluid. The specimen was sectioned and stained with hematoxylin and eosin, Bodian's silver impregnation, phosphotungstic acid-hematoxylin, Masson's trichrome, PAS2 -Alcian blue, toluidine blue at pH 2 and pH 4, and Gomori's reticulum stain. This lesion is registered as Specimen RTLA 272 in the Registry of Tumors in Lower Animals, Museum of Natural History, Smit...
