Solanum glaucophyllum (waxy nightshade) is one of the few plants that naturally produces 1,25-dihydroxycholecalciferol glycosides (1,25(OH)2D3-gly). In the literature it is mentioned that the glycosides are cleaved before absorption and thus only the aglycone is absorbed. However, no data are known so far that confirm this assumption analytically. In a multi-stage approach, this question is to be clarified in vitro. To do this, a number of preliminary tests must first be carried out, including one focusing on possible cell toxicity. Since the cell toxicity of 1,25(OH)2D3-gly can only be extrapolated from the data for synthetic 1,25(OH)2D3 to a limited extent, this experiment serves to determine the maximum possible dose.

The overall aim of the HELCOM BLUES project is to support regional capacity, coordination and cooperation with regards to developing effective measures to secure good status of the marine environment. This includes provisioning, and making available, necessary knowledge to advance the development and implementation of joint measures addressing common pressures, as well as to provide concrete support to the decision-making process within the Baltic Sea region.
The task carried out by TiHo focuses on highly mobile and under-reported groups (here: cetaceans), and considers several aspects identified in recent HELCOM review processes to be knowledge/assessment gaps and aspects of high regional priority. The harbour porpoise can be categorised as both a highly mobile and an under-reported species in the Baltic Sea region. At present, there are no functional regional HELCOM indicator(s) to assess status for abundance or distribution, which are two of the primary Marine Strategy Framework Directive criteria under MSFD D1. This clear gap was identified as a high priority for the HELCOM region. This task will provide support for the HELCOM indicator team and focus on improving methods and operational assessments of harbour porpoise abundance by HOLAS III, and on harmonising methods of assessment with other EU regions (i.e. OSPAR and HELCOM). The main aspects addressed by TiHo are:
1) Establishment of a harmonised approach to indicator development for harbour porpoises between HELCOM and OSPAR (of particular relevance to shared marine areas);
2) Assessing trend in abundance for assessment of the Belt Sea population;

Project Details:
Das MERS-CoV (Middle East Respiratory Syndrome Coronavirus) ist die Ursache einer schweren und oft auch tödlich verlaufenden Atemwegserkrankung beim Menschen. Da das Virus natürlicherweise im Dromedar zirkuliert, welches vor allem auf der Arabischen Halbinsel ein sehr bedeutsames Nutztier mit engen Kontakt zum Menschen ist, stellt das Virus eine große Herausforderung als zoonotisches Pathogen dar. Dromedare scheiden das Virus in großen Mengen mit Ex- und Sekreten aus, sodass eine Übertragung auf den Menschen sehr produktiv ist, wohingegen die Mensch-zu-Mensch-Übertragung weniger epidemiologisch bedeutsam ist.
Um die derartige Infektionskette zu unterbrechen und um den Menschen vor einer Infektion zu schützen, ist es demnach von Bedeutung, die Virusausscheidung des natürlichen Virusreservoirs und damit des Dromedars zu verhindern. Die hierbei vielversprechendste Methode scheint die wirksame Vakzinierung des Dromedars als natürlicher Viruswirt zu sein.
Bei dem zu untersuchenden Impfstoff handelt es sich um MVA-MERS-S. Hierbei wird das Gen des S Proteins von MERS-CoV in das Genom von MVA (Modifiziertes Vaccinia Virus Ankara) eingebaut, sodass dieses replikationsdefiziente und als sicher getestetes Vektorvirus das MERS CoV S Protein exprimiert und so voraussichtlich zu einer Immunität des Dromedars gegen MERS CoV führt.
Das Ziel des Projektes besteht darin, die Immunogenität und protektive Wirksamkeit des Impfstoffes im Dromedar zu überprüfen. Dabei wird die bestwirksamste Applikationsroute des Impfstoffes ermittelt, das Level und die Langlebigkeit der Immunantworten (inklusive T Zellen), welche aufgrund der Vakzinierung induziert werden, charakterisiert und letztlich die Fähigkeit des Impfstoffes eine Virusausscheidung zu verhindern, untersucht.

Project Details:
The reduction of the salt content is a regularly discussed topic in recent years, which should be considered by the food processing industry, for example through a reduction or the replacement of sodium chloride with other substances such as potassium or magnesium chloride. In addition to the sensory properties that are mainly perceived by consumers, however, technological and microbiological parameters are also important. The aim of this study is therefore to produce raw sausages and cooked cured meats both with reduced sodium chloride concentrations and with the addition of potassium and magnesium chloride and to analyse both the sensory and other parameters. The aim is to show which (minimum) concentrations of sodium chloride or salt substitutes can be used to produce products that are acceptable for consumers in terms of food quality and, in particular, safety.

Project Details:
CoVid-19 is characterized by infection of the airways by SARS-CoV-2. Apart from the respiratory tract, other organs are also involved, e.g. the intestinal tract. The importance of the intestinal infection is increasingly recognized. In a large proportion of pediatric patients, virus was detected in rectal swabs and virus shedding from the intestine was found even when oral swabs had become negative. Therefore, prolonged virus shedding and fecal-oral transmission have to be considered. This notion is supported by detection of the virus in wastewater.
The aim of this short project is to apply intestinal cell cultures to characterize the infection of differentiated intestinal epithelial cells by SARS-CoV-2 and thereafter intestinal orgranoids.
This in vitro infection approach will target the following aims:
1. Characterization of the replication efficiency of SARS-CoV-2 (virus yield, virus exit, virus entry, apical, basolateral).
2. Localization of the cellular receptor(s) in human intestinal Caco-2 cells
3. Investigation of the trafficking of the cellular receptor(s), determination and subsequent modulation of their mode of interaction with membrane microdomains (lipid rafts, LRs)
4. Effects of glycosylation modulators on the spike glycoprotein and its interaction with intestinal cells
5. Implication of virus infection on the trafficking and function of crucial enzymes of the intestinal physiology (APN, SI, LPH, DPP4).
This project will provide substantial information on the replication of SARS-CoV-2 in intestinal epithelial cells, evaluate its effects on the intestinal function and provide solid hypotheses on the molecular and biochemical basis for the symptoms elicited by SARS-CoV-2 infections. These hypotheses can be then examined at a later stage in intestinal organoids. Further, unravelling the biosynthetic pathway, glycosylation pattern and mode of interaction of the SARS-CoV-2 receptors and its modulation could constitute exquisite targets for potential therapy.

Ziel des Projektes ist das Vorkommen von Anti-Sperma-Antikörpern und Leukozyten im Samen einer Population von Warmblutzuchthengsten zu untersuchen. Weiterhin sollen die Auswirkungen von Anti-Sperma-Antikörpern und Leukozyten auf die Spermaqualität der betroffenen Hengste und die Entwicklung belegungsinduzierter Entzündungsreaktionen bei Stuten erforscht werden.
