In den Akten des Ministeriums für Staatssicherheit der DDR MfS finden sich unzählige Fotodokumente über gescheiterte Fluchtversuche an der Berliner Mauer. Arwed Messmer (* 1964) trug für seine Bildcol­lage Fotos und fotografierte Asservate aus der Stasi­unterlagenbehörde BStU zusammen. Es entstand eine eindrucksvolle, komplexe Collage aus gefunde­nen, bearbeiteten oder neu kontextualisierten Bild­dokumenten und eigenen Fotografien. Eine Arbeits­methode, die der Fotokritiker Gerry Badger »eine künstlerische Neubewertung von Geschichte« nann­te. 25 Jahre nach dem Fall der Mauer thematisiert Reenactment MfS einen wichtigen Aspekt der jünge­ren deutschen Geschichte neu, in alternativer Positi­on zur zeithistorischen Betrachtung und Verwen­dung von Fotografie. Mit »dokumentarischer Empa­thie«, wie Florian Ebner formulierte, stellt Messmer die Frage nach der Authentizität des dokumentari­schen Bildes, das nie ganz frei von Inszenierung sein kann. Siegertitel Silber beim Deutschen Fotobuchpreis 2016

Ochratoxin A (OTA), a nephrotoxic compound produced by certain Aspergillus and Penicillium species, is one of the most abundant mycotoxins in food commodities. Aspergillus carbonarius is the main source of OTA in wine, grape juice and dried vine fruits. Although many studies have focused on OTA production by A. carbonarius, little is known about the genes related to OTA production and transport. We have found a transporter that belongs to the major facilitator superfamily (MfsA) which is highly expressed with a 102-fold induction in an ochratoxigenic A. carbonarius strain compared to a low OTA producer strain. The encoding mfsA gene shows similarity to the multidrug efflux transporter flu1 from Candida albicans. A high number of putative transcription factor binding sites involved in the response to stress were identified within the promoter of mfsA. Phenotypical analysis of δ. mfsA deletion mutants revealed that the loss of mfsA leads to a slight growth reduction and increased OTA production. We therefore hypothesize that MfsA could be a stress response transporter whose disruption could cause an increase in oxidative stress together with a stimulation of mycotoxin production. •A. carbonarius mfsA expression is induced over 100 fold in an OTA producing strain.•mfsA gene has been cloned and sequenced.•An A. carbonarius δmfsA null mutant has been obtained by ATMT.•The δmfsA null mutants produce more OTA than the parental strain.•The expression of mfsA is up regulated by hydrogen peroxide. ; A.

The Prestige oil spill crisis (2002–2003), one of the worst oil spills that affected the Atlantic Spanish coastal line, pointed out that some management tools are needed in the form of laws, regulations and technical procedures. In particular, the issues are contingency planning and prevention against marine pollution and prediction for a proper response. In that background, the Catalan local government approved the CAMCAT (2004), a Regional contingency plan against marine pollution, to be framed within the (Spanish) National Contingency Plan. The CAMCAT contemplated the implementation of a Regional Forecasting System for the North-Western Mediterranean area, intended to help Catalan Authorities during any pollution emergency. The Laboratory of Maritime Engineering (LIM/UPC) has been responsible for the implementation of this Regional CAMCAT Forecasting System that is based (nested) on existing larger Forecasting Systems/Products, and it integrates several coastal observational data. The present paper is aiming to make an overview of the several scientific and technical activities related to the implementation and validation of the CAMCAT System.
