Thioxanthone: on the shape of the first absorption band
2010
The equilibrium ground state geometry of thioxanthone (TX) has been investigated and its effect on the vertical excitation energies and photophysical behaviour has been explained. In line with this purpose, the first absorption band of TX has been simulated and analysed in detail. The calculations show that TX is planar, C(2v) symmetric in its ground state. The energy of the low-lying excited states seems to be rather insensitive along the butterfly motion coordinate. The shoulder in the first absorption band (at around 3.43 eV) is shown to be caused by vibrational progression of various in-plane modes and does not justify the hypothesis that two photophysically distinct conformers of TX ex…
Interligand Electron Transfer Determines Triplet Excited State Electron Injection in RuN3−Sensitized TiO2 Films
2004
Electron injection from the transition metal complex Ru(dcbpy)(2)(NCS)(2) (dcbpy = 2,2'-bipyridine-4,4'-dicarboxylate) into a titanium dioxide nanoparticle film occurs along two pathways. The dominating part of the electron injection proceeds from the initially excited singlet state of the sensitizer into the conduction band of the semiconductor on the sub-hundred-femtosecond time scale. The slower part of the injection occurs from the thermalized triplet excited state on the picosecond time scale in a nonexponential fashion, as was shown in a previous study (Benko, G.; et al. J. Am. Chem. Soc. 2002, 124, 489). Here we show that the slower channel of injection is the result of the excited s…
The role of mycotoxins in neurodegenerative diseases: current state of the art and future perspectives of research
2021
Abstract Mycotoxins are fungal metabolites that can cause various diseases in humans and animals. The adverse health effects of mycotoxins such as liver failure, immune deficiency, and cancer are well-described. However, growing evidence suggests an additional link between these fungal metabolites and neurodegenerative diseases. Despite the wealth of these initial reports, reliable conclusions are still constrained by limited access to human patients and availability of suitable cell or animal model systems. This review summarizes knowledge on mycotoxins associated with neurodegenerative diseases and the assumed underlying pathophysiological mechanisms. The limitations of the common in vivo…
The Importance of Multilingual Information and Plain English in Response to the COVID-19 Pandemic
2021
Health is a common issue for all human beings. As a consequence, everyone in the world has in some way to cope with the language of medicine. This is true now more than ever due to the global health crisis caused by the current COVID-19 pandemic, which has introduced a great amount of terms, previously mostly used by epidemiologists and statisticians, but which now have entered the daily lexicon of many languages. As the medium of international scientific communication, English is the language of worldwide information about the pandemic, and the main source of terms and expressions for other languages. The impact of the COVID-19 pandemic on English lexicon has been so deep that the Oxford E…
The new world of human genetic technologies: The policy environment and impacts of genetic screening tests
1995
Today it is possible to screen for mutated DNA sequences which do not induce any diseases but predispose to develop diseases under certain environmental condition. These latter disorders are called “multifactorial” since they result from the interplay of genetic and environmental factors. Among multifactorial disorders there are job-related diseases whose genetic component can be identified by genetic screening tests. The use of these tests to predict occupational disorders, to cut down on them, and to save costs—in particular for absenteeism, health care, and lawsuits—is of interest to employers and insurers. As for employees, it could entail an extremely deep invasion of privacy, economic…
Safety Related Behaviors and Law Adherence of Shared E-Scooter Riders in Germany
2021
Shared e-scooters, whose supply and coverage keeps increasing in many cities around the globe, are rapidly changing mobility in urban road environments. As rising injury rates have been observed alongside this new form of mobility, researchers are investigating potential factors that relate to safe/unsafe e-scooter use. In Germany, e-scooter sharing platforms were only recently permitted in the middle of 2019, and their number has increased steadily since then. The aim of this study was to assess key factors that relate to their safe use, through a direct observation of e-scooters conducted at three observation sites around Berlin. Helmet use, dual use, type of infrastructure use, and trave…
Limited liability companies in Poland
2020
This study discusses the construction of a limited liability company (LLC) under Polish law. Due to the short length of the article and the large scale of the issue, this study is limited to the presentation of basic concepts. The construction of an LLC under Polish law is flexible and has been modernised, as a result of a number of amendments, including a fast registration path.
Wache Videolaryngoskopie
2016
Introduction Awake video laryngoscopy is a novel option in airway management that is drawing more and more attention as an alternative to awake endoscopic guided intubation.Main issues: Intubation under preserved spontaneous breathing is the safest method to secure the expected difficult airway. In direct comparisons to awake flexible endoscopic intubation, awake video laryngoscopy achieves satisfactory intubation times and a high acceptance of patients and anesthesiologists. Specific cases, in particular very limited mouth opening or sub-glottic masses, require awake flexible endoscopic intubation. Sufficient topical anesthesia and a sophisticated sedation protocol are prerequisites for su…
2-Aminopurine non-radiative decay and emission in aqueous solution: A theoretical study
2008
Abstract The minimum energy path along the lowest-lying ππ ∗ excited state of 2-aminopurine was calculated to elucidate the mechanisms of radiationless decay and emission in water. The sequential Monte Carlo quantum mechanics approach with a multiconfigurational and perturbative description of the wave function was employed to compute the minimum, transition state, and conical intersection. It was found that the barrier in the potential energy surface to access the conical intersection funnel increases in aqueous environment, making the system prone to enlarge the emission yield. These results rationalize the observed enhancement of emission in 2-aminopurine upon increasing of the solvent p…
