Acute impact of dietary pattern and walking on postprandial metabolism, attention, and mood in older adults with a cardiovascular disease risk phenotype
Diekmann, Christina (2020-01-27)Attenuating the postprandial stress response and its associated inflammatory and endothelial events through specific nutritional and lifestyle interventions seems to be a promising and important approach to decrease the ... -
Adiponectin in Cattle: Profiling of molecular weight patterns in different body fluids at different physiological states and assessment of adiponectin’s effects on lymphocytes
Heinz, Johanna Franziska Lisa (2014-07-07)Adiponectin (AdipoQ), one of the most abundant adipokines found in circulation exerts various meta-bolic functions, e.g. improving insulin sensitivity and ameliorating tissue inflammation. It is secreted in different ... -
Analyses of immune competence traits and their association with candidate genes in pigs
Phatsara, Chirawath (2007)The present study was carried out to investigate the immune competences of a backcross DUMI population. Complement activity via classical and alternative pathways were determined using haemolytic activity assay. Antibodies ... -
Ansätze zur Untersuchung der genetischen Ursachen für den Erbfehler Stülpzitze beim Schwein
Jonas, Elisabeth (2007)Der Gesäugekomplex ist bei Säugetieren für die Versorgung der Nachkommen mit Nährstoffen und für die Immunisierung über die Kolostralmilch von Bedeutung. Die ersten Anlagen der Zitzen sind in der fötalen Entwicklung früh ... -
Antichlamydiale Wirkung mehrfach ungesättigter Fettsäuren
Sauerwein, Helga; Jaudszus, Anke (2012)Ziel des vorliegenden Forschungsvorhabens war eine potentiell Chlamydien-infektionsmindernde Wirkung von mehrfach ungesättigten Fettsäuren an zwei humanen und einer bovinen Epithelzelllinie zu untersuchen. Die Zellkultur ... -
Blauzungenkrankheit bei Rind und Schaf: Art und Umfang der entstehenden Verluste in der Produktion anhand von Beispielbetrieben in Nordrhein-Westfalen sowie Monitoring der Impferfolge
Müller, Ute; Sauerwein, Helga (2010)Ziele des vorliegenden Forschungsvorhabens waren zum einen die Quantifizierung der Produktionseinbußen in Beispielbetrieben: eine Besamungsstation, vier Milchviehbetriebe und vier Schafbetriebe. Zum anderen erfolgte das ... -
Cellular energy supply and aging in dairy cows: Characterization of different physiological states and impact of diet-induced over-condition
Laubenthal, Lilian (2015-09-24)Lactation in dairy cows is accompanied by dramatic changes in energy balance and thus requires the continued adaption of the key organs, namely adipose tissue (AT), liver, and mammary gland to the varying conditions. The ... -
Challenges related to statistical methods and sensor systems for the daily prediction of health disorders in individual dairy cows
Post, Christian (2023-02-02)The use of digital support systems has become a standard in dairy farming, and significant effort has been made to detect individual animals that are in need for a treatment by using sensor data. However, developing systems ... -
Changes of inner teat morphology caused by the milking process and by incomplete milking during dry-off as assessed by innovative technologies
Martin, Lisett Marie (2020-03-03)In dairy farming, the timing of the lactation cycle and the way of milk removal differ considerably from the natural conditions. Ensuring good health and wellbeing of farm animals is of great interest from both an economic ... -
Characterization of adiponectin at different physiological states in cattle based on an in-house developed immunological assay for bovine adiponectin
Singh, Shiva Pratap (2014-02-07)Adipose tissue (AT), through secretion of adipokines, plays a central role in regulating metabolism. Adiponectin is one of the most abundant adipokines and is linked with several physiological mechanisms such as insulin ... -
Characterization of insulin sensitivity and inflammation related factors in dairy cows receiving conjugated linoleic acids (CLA) or a control fat supplement during lactation
Saremi, Behnam (2013-08-20)With the onset of lactation, dairy cows have to mobilize body reserves, mainly body fat, to cover the output of energy via milk. The homeorhetic metabolic adaptation to the needs of milk production is accomplished through ... -
Characterization of porcine milk exosomes from different stages of lactation
Furioso Ferreira, Rafaela (2023-05-11)Exosomes are membranous vesicles considered major players in cell-cell communication. Milk provides adequate nutrition, transfers immunity, and promotes neonate development, and milk exosomes are suggested to have a key ... -
Chlamydien-Infektionen bei Milchvieh: Untersuchung zur Verbreitung in Betrieben Nordrhein-Westfalens
Müller, Ute; Kemmerling, Kirsten; Sauerwein, Helga (2008)Chlamydieninfektionen werden für eine Reihe von Fruchtbarkeitsstörungen und Atemwegserkrankungen beim Rind in Verbindung gebracht. Die entsprechende Literatur basiert in erster Linie auf serologischen Untersuchungen und ... -
Chlamydieninfektionen bei Milchkühen in Nordrhein-Westfalen, Prävalenz, Risikofaktoren, Kennziffern und Vorhersagewahrscheinlichkeiten
