Project Details:
A blood test provides information on the physiological or pathological status of an animal. In veterinary medicine, another focus is on monitoring the nutritional status of a patient. The patient's results, obtained through sampling and appropriate analysis procedures, are categorised with previously established RI of a healthy reference population. The laboratory results provide important information for the diagnosis and prognosis of a sick animal. In addition to correct analysis, the reliability of laboratory results requires quality-assured pre-analysis and appropriate and evidence-based RI. Even accurate measurement results can lead to incorrect diagnosis and therapy if the sample has been altered at the time of analysis to such an extent that it no longer corresponds to the basic population of the previously used reference population. Many factors influence the quality of samples in the pre-analytical phase and the basis for assessment in the post-analytical phase. The aim of this project is therefore, for the first time, to focus significantly more on pre-analytical factors in the production of RI. In order to avoid diagnostic errors, pre-analytical workflows should be standardised as far as possible. According to a thorough literature search, the RIs of the following parameters in particular differ significantly from each other and will therefore be reproduced in this paper using a reference population. In particular, this will be done with very clearly defined pre-analytical conditions. From clinical chemistry, aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transferase (GGT), glutamate dehydrogenase (GLDH), creatine kinase (CK), total protein (TTP), albumin, total bilirubin, urea, beta-hydroxybutyrate (ß-HBS), free fatty acids (FFA), cholesterol and various minerals are considered.
The aim is to further develop and establish recommendations that can be implemented in daily practice and laboratory work in veterinary medicine, are based on current and quality-assured RI for dairy cows from Germany and lead to meaningful laboratory results.

Project Details:
Sensor-based devices are increasingly used to objectify lameness and other gait abnormalities in horses. Recording the ground reaction forces of the hooves is the gold standard but measurements require well equipped facilities and significant effort. With the help of pressure boots, which can be easily attached to the horse's hooves, their pressure on the ground and position during locomotion can be determined. Data will be compared to established kinetic (pressure measuring plate) and kinematic methods (Equinosis Lameness LocatorTM).

The objective of this prospective randomised clinical trial is to evaluate the occurrence of post-operative ileus as well as the short- and long-term outcome with the use of two different suture patterns for jejunojejunal anastomosis. Furthermore, histomorphology and several markers for inflammation, cell death, the enteric nervous system and stem cells will be evaluated in intestinal samples taken from the resection margins. In cases necessitating anastomotic revision or euthanasia, this (immuno-)histological examination will also be performed on the anastomosis itself. Determining the expression and distribution of these markers will enable the characterisation of this tissue prior to and following anastomosis and possibly identify causes for post-operative ileus or anastomotic failure.

Project Details:
In order to be able to accompany the evaluation process of the spatial development plan (ROP) from the perspective of marine nature conservation, a nature conservation-based, ecosystem-based planning contribution is to be developed as part of the project, which can be integrated into the marine spatial development plan (MSP) update process in a targeted manner.
In order to enable a synthesis of the information relevant for the planning contribution, the current state of knowledge from completed and ongoing research projects will be researched. Together with additional sensitivity analyses, content for the integration of ecosystem-relevant aspects into the planning contribution will be developed. In addition, various scenarios for the expansion of offshore wind power will be developed and evaluated in order to establish the necessary conditions for an environmentally compatible expansion of renewable energies in the North and Baltic Seas. The project is thus intended to provide an overall spatial planning concept for marine protection that can be incorporated by the BfN into the process of evaluating and updating the MSP.
BioConsult GmbH & Co KG is carrying out the BfN research project as contractor.
The following work on marine mammals is being carried out as a contribution by the TiHo:
- Compilation and preparation of the available distribution data in the form of maps, diagrams and tables with textual explanations
- Identification and presentation of important habitats for indicator species (e.g. harbor porpoise, harbor seal, grey seal)
- Effects of three scenarios of OWP expansion

The aim of this study is the validation of the automated analysis of cell count in bovine synovia using the ADVIA 2120i. Corresponding reference ranges for clinically normal joint aspirates should be developed to differentiate these from pathological samples. In addition, further examinations such as the determination of protein content and a microbiological examination of the samples are carried to analyse whether particular parameters can provide information on clinical appearance, diagnostics or therapy. Both macroscopically abnormal and normal joint aspirates are used for examination.

The aim of this study is to analyse the effect of four distict cytokines, which are important in early bovine pregnancy, on the gene expression in cultured primary bovine hepatocytes. PCR is used to detect how the hepatocellular IGFBP-expression changes when the cells are stimulated with different cytokines in different concentrations. This demonstrates the connection between immunological and endocrine changes in early pregnant cows. We particularly focus on IFNτ, the embryonic pregnancy recognition signal of ruminants.
