The aim of our experiment Phage and Uracil Response was to extend the use of bacteriophage T7 and uracil biological dosimeters for measuring the biologically effective ultraviolet (UV) dose in the harsh extraterrestrial radiation conditions. The biol

We studied the complexation of meso-tetrakis(4-N-methylpyridyl)porphyrin (TMPyP) with HeLa nucleosomes and compared it to our earlier results on T7 phage nucleoprotein complex (NP) and isolated DNA. To identify binding modes and relative concentratio

In this work we wanted to verify that photoactivation of DNA-non-binding porphyrin derivative hematoporphyrin IX (Hp) is able to induce damages in DNAs of various accessibilities such as B-conformation and superhelical isolated DNA, nucleoprotein com

We studied the complex formation of tetrakis(4-N-methylpyridyl)porphyrin (TMPyP) with double stranded DNAs and T7 phage nucleoprotein complex. We analyzed the effect of base pair composition of DNA, the presence of capsid protein, and the composition

The biological dosimetry of the solar UV radiation functioned correctly on the Earth’s surface. The aim of the present studies was to extend the dosimetry to the extraterrestrial solar radiation in LEO. Similar to the Earth’s surface bacteriophag

The risk of transmitting infections by blood transfusion has been substantially reduced. However, alternative methods for inactivation of pathogens in blood and its components are needed. Application of photoactivated cationic porphyrins can offer an

We investigated the efficiency and the mechanism of action of two glycoconjugated tetraphenyl porphyrins in their photoreaction with T7 bacteriophage. Both types of porphyrins sensitized the photoinactivation of T7, but the slopes of inactivation kin

We investigated the efficiency and the mechanism of action of a tetraphenyl porphyrin derivative in its photoreaction with T7 phage as surrogate of non-enveloped DNA viruses. TPFP was able to sensitize the photoinactivation of T7 phage in spite of th
