[New photo-induced effects of reactivation and protection of yeast cells under lethal UVB radiation]

Autor: G Ia, Fraĭkin, N S, Belenikina, E V, Piniaskina, A B, Rubin

Publikováno v: Izvestiia Akademii nauk. Seriia biologicheskaia. (6)

Brief exposure of yeasts to low-intensity monochromatic light (400-730 nm) has revealed the effects of photoreactivation and photoprotection of the cells inactivated by medium wave UVB radiation (290-320 nm). The red spectral region with a maximum at

[Photodynamic damage of yeast subcellular fraction induced by elevated levels of endogenous protoporphyrin IX]

Autor: A O, Shumarina, M G, Strakhovskaia, V B, Turovetskiĭ, G Ia, Fraĭkin

Publikováno v: Mikrobiologiia. 72(4)

The 2,2'-dipyridyl-induced accumulation of protoporphyrin IX in Saccharomyces cerevisiae cells was shown to be accompanied by the photoinhibition of cell respiration and the enhancement of the photoinduced permeability of plasma membranes to the fluo

[Fluorescent photobleaching of endogenous protoporphyrin IX in yeast cells]

Autor: M G, Strakhovskaia, A O, Shumarina, G Ia, Fraĭkin, A B, Rubin

Publikováno v: Biofizika. 47(5)

Yeast Saccharomyces cerevisiae accumulate in the presence of chelator 2,2'-dipyridyl, two fractions of photosensitizer protoporphyrin IX, which fluoresce with maxima at 625 and 635 nm. The two fractions were found to differ from each other in the dyn

[Study of fluorescence from isolated yeast plasma membranes in visible range of the spectrum]

Autor: M G, Strakhovskaia, E V, Vlasova, G Ia, Fraĭkin

Publikováno v: Biofizika. 43(3)

The fluorescence with maximum at 683 nm from isolated yeast plasma membranes has been detected. The fluorescence was due to a membrane-bound compound absorbing in the visible range of the spectrum. The fluorescence excitation spectrum of this compoun

[Protective and reactive effect of a cellular extract from propionic acid bacteria on Candida guilliermondii and Escherichia coli, inactivated by ultraviolet radiation]

Autor: G Ia, Fraĭkin, L I, Vorob'eva, E Iu, Khodzhaev, E V, Piniaskina, G M, Ponomareva

Publikováno v: Mikrobiologiia. 64(6)

Dialyzed soluble proteins of Propionibacterium freudenreichii subsp. shermanii cell extract (dialyzate) were found to exert a protective and reactivating effect on Candida guilliermondii and Escherichia coli cells inactivated by UV light of C and B r

[Mechanism of NADH-sensitized formation of DNA breaks during irradiation with near UV light]

Autor: T G, Burchuladze, G Ia, Fraĭkin

Publikováno v: Molekuliarnaia biologiia. 25(4)

NADH-photosensitized in vitro formation of single-stranded breaks in plasmid DNA pBR322 depends on both the concentration of the sensitizer and the influence of near-UV radiation (320-400 nm). Scavengers and inhibitors of different activated oxygen s

[Sensitized NADH formation of single-stranded breaks in plasmid DNA upon the action of near UV-radiation]

Autor: T G, Burchuladze, E G, Sideris, G Ia, Fraĭkin

Publikováno v: Biofizika. 35(5)

It has been shown that NADH photosensitize in vitro single-strand breaks formation in double-strand plasmid DNA pBR 322 upon near-UV (320-400 nm) irradiation. The number of single-strand breaks depends both on UV light dose and sensitizer concentrati
