Maximum uptake of liposome-encapsulated fluorescein diacetate by Daucus carota protoplasts was observed when 6 x 10(6) protoplasts per milliliter were incubated with 2.4 x 10(7) liposomes per milliliter for 1 hour. In the case of Nicotiana glutinosa protoplasts, optimum ratio of protoplasts to liposomes was 1:10, where 2.3 x 10(5) protoplasts per milliliter were provided. Neutral and positive l...
The cellular and subcellular localization of endogenous nitric oxide (NO.) in leaves from young and senescent pea (Pisum sativum) plants was studied. Confocal laser scanning microscopy analysis of pea leaf sections with the fluorescent probe 4,5-diaminofluorescein diacetate revealed that endogenous NO. was mainly present in vascular tissues (xylem and phloem). Green fluorescence spots were also...
TNF promotes skeletal muscle weakness, in part, by depressing specific force of muscle fibers. This is a rapid, receptor-mediated response, in which TNF stimulates cellular oxidant production, causing myofilament dysfunction. The oxidants appear to include nitric oxide (NO); otherwise, the redox mechanisms that underlie this response remain undefined. The current study tested the hypotheses tha...
Regulations for ballast water treatment specify limits on the concentrations of living cells in discharge water. The vital stains fluorescein diacetate (FDA) and 5-chloromethylfluorescein diacetate (CMFDA) in combination have been recommended for use in verification of ballast water treatment technology. We tested the effectiveness of FDA and CMFDA, singly and in combination, in discriminating ...
Osteoporosis is a serious health problem characterized by decreased bone mineral density and deterioration of bone microarchitecture. Current antiosteoporotic agents exhibit a wide range of adverse effects; meanwhile, phytochemicals are effective and safer alternatives. In the current work, nine compounds belonging to hydroxyphenylalkane and diarylheptanoid groups were isolated from Aframomum m...
Structureactivity relationships of nine thiophenes, 2,2': 5',2″-terthiophene (1), 2-chloro-4-[5-(penta-1,3-diyn-1-yl)thiophen-2-yl]but-3-yn-1-yl acetate (2), 4-(2,2'-bithiophen-5-yl)but-3-yne-1,2-diyl diacetate (3), 4-[5-(penta-1,3-diyn-1-yl)thiophen-2-yl]but-3-yne-1,2-diyl diacetate (4), 4-(2,2'-bithiophen-5-yl)-2-hydroxybut-3-yn-1-yl acetate (5), 2-hydroxy-4-[5-(penta-1,3-diyn-1-yl)thiophen-...
