Oxidised guanidinohydantoin (Ghox) and spiroiminodihydantoin (Sp) are major products of iron- and copper-mediated 8-oxo-7,8-dihydroguanine and 8-oxo-7,8-dihydro-2-deoxyguanosine oxidation

Description :
8-Oxo-7,8-dihydroguanine (8-oxoGua), an important biomarker of DNA damage in oxidatively generated stress, is highly reactive towards further oxidation. Much work has been carried out to investigate the oxidation products of 8-oxoGua by one-electron oxidants, singlet oxygen, and
peroxynitrite. This ...

Agent-based modelling of viral infection.
Author(s) :
Perrin, Dimitri
Description :
The three phases of the macroscopic evolution of the HIV infection are well-known, but it is still difficult to understand how the cellular-level interactions come together to create this characteristic pattern and in particular why there are such differences in individual responses. An “agent-based...

Description :
We describe an experimental system designed for single-shot photoelectron spectroscopy on free atoms and molecules at the Free Electron Laser in Hamburg (FLASH at DESY). The combination of the extreme ultra-violet (EUV) Free Electron Laser and a temporally synchronized optical fs laser (Ti:Sapphire)...

Sulphur overlayers on the Au(110) surface: LEED and TPD study
Description :
The adsorption and desorption of sulphur on the clean reconstructed Au(1 1 0)–(1 × 2) surface has been studied by low energy electron diffraction, Auger electron spectroscopy and temperature programmed desorption. The results obtained show a complex behaviour of the S/Au(1 1 0) system during sulphur...

N-Ferrocenylmethyl-2-(3-methylstyryl)-N’-methylbenzimidazolium hexafluorophosphate
Description :
In the title compound, [Fe(C5H5)(C23H22N2)]PF6, the F atoms of the [PF6]- anion are disordered over four different orientations with equal occupancies. In the cation, the five-membered imidazolium ring forms dihedral angles of 71.48 (10) and 19.83 (10)° with the substituted C5H4 ring and the benzene...

A study of clinical strains of Pseudomonas Aeruginosa and the investigation of antibiotic resistance mechanisms in the multidrug resistant strain PA13
Author(s) :
Ferguson, Damien
Description :
Thirteen clinical strains of bacteria from two Irish hospitals were identified as Pseudomonas aeruginosa using classical methods, API 20NE and Biolog GN. Their identification was confirmed by 16S rRNA gene sequencing. The antibiotic resistance profiles of the isolates were determined against forty-o...

Description :
Understanding the nature of the instabilities of LBVs is important to understand the late evolutionary stages of very massive stars.
We investigate the long term, S Dor-type variability of the luminous blue variable
GR290 (Romano’s star) in M33, and its 2006 minimum phase.
New spectroscopic and phot...
