History and development of radiation-protective agents

Abstract: Purpose: The search for ideal protective agents for use in a variety of radiation scenarios has continued for more than six decades. This review evaluates agents and procedures that have the potential to protect against acute and late effects of ionising radiation when administered either before or after radiation exposure.Conclusion: Over the years, extensive experimental studies of radiation-protective agents have enhanced our knowledge of radiation physics, chemistry, and biology. However, translation of agents from animal testing to use in various scenarios, such as prophylactic adjuncts in radiotherapy or post-exposure treatments for potential victims of radiation accidents/incidents, has been slow. Nevertheless, a number of compounds are now available for use in a variety of radiation situations. These include agents approved by the U.S. Food and Drug Administration for use in reducing exposure to internal radionuclides (Prussian blue, calcium diethylenetriamene pentaacetate (DTPA) and zinc DTPA, po...

Measurement of beauty production from dimuon events at HERA

Abstract: Beauty production in events containing two muons in the final state has been measured with the ZEUS detector at HERA using an integrated luminosity of 114 pb(-1). A low transverse-momentum threshold for muon identification, in combination with the large rapidity coverage of the ZEUS muon system, gives access to almost the full phase space for beauty production. The total cross section for beauty production in e p collisions at root s = 318 GeV has been measured to be sigma(tot)(ep -> b (b) over barX) = 13.9 +/- 1.5(stat.)(-4.3)(+4.0)(syst.) nb. Differential cross sections and a measurement of b (b) over bar correlations are also obtained, and compared to other beauty cross-section measurements, Monte Carlo models and next-to-leading-order QCD predictions.

FungalTraits: a user-friendly traits database of fungi and fungus-like stramenopiles

Abstract: The cryptic lifestyle of most fungi necessitates molecular identification of the guild in environmental studies. Over the past decades, rapid development and affordability of molecular tools have tremendously improved insights of the fungal diversity in all ecosystems and habitats. Yet, in spite of the progress of molecular methods, knowledge about functional properties of the fungal taxa is vague and interpretation of environmental studies in an ecologically meaningful manner remains challenging. In order to facilitate functional assignments and ecological interpretation of environmental studies we introduce a user friendly traits and character database FungalTraits operating at genus and species hypothesis levels. Combining the information from previous efforts such as FUNGuild and Fun(Fun) together with involvement of expert knowledge, we reannotated 10,210 and 151 fungal and Stramenopila genera, respectively. This resulted in a stand-alone spreadsheet dataset covering 17 lifestyle related traits of fungal and Stramenopila genera, designed for rapid functional assignments of environmental studies. In order to assign the trait states to fungal species hypotheses, the scientific community of experts manually categorised and assigned available trait information to 697,413 fungal ITS sequences. On the basis of those sequences we were able to summarise trait and host information into 92,623 fungal species hypotheses at 1% dissimilarity threshold.
