Kellersmann, Julia (2004)O-glykosidisch gebundenes N-Acetylglucosamin (O-GlcNAc) an Serin- und Threoninresten von Proteinen ist eine posttranslationale Modifikation von cytosolischen Proteinen, Kernproteinen und cytoplasmatischen Domänen von ... -
Der Einfluss von Nonylphenolen auf die Entwicklung des Nervensystems und die synaptische Plastizität
Jockschat, Carina (2019-11-13)Bei Nonylphenolen handelt es sich um eine Gruppe chemischer Verbindungen mit aromatischem Ring, Hydroxylgruppe und einer Nonyl-Seitenkette, die entweder verzweigt oder linear vorliegen kann. Das technische Nonylphenol ... -
Endocrine activity of adipose tissues as influenced by energy intake in the periparturient cow
Weber, Martina (2016-02-09)With the onset of lactation, dairy cows have to mobilize body reserves, mainly in form of fat, to cover the energy output via milk. Homeorhetic adaptations, achieved via the orchestrated actions of hormones, are necessary ... -
Epigenetic and exosome-mediated cell-cell communication in follicular cells and preimplantation embryos
Zidane, Mohammed Saeed (2017-12-21)Follicular cells and preimplantation embryos communication with their in vivo or in vitro environments via mechanisms including cell adhesion and extracellular vesicles is crucially essential for normal oocyte and embryo ... -
Epigenetic regulation of CD14 in TRIF pathway in pulmonary alveolar macrophages of German Landrace pigs
Yang, Qin (2016-05-24)Diseases of the respiratory system are a main problem in pig production. Pulmonary alveolar macrophages (PAMs) are key players to defend these respiratory diseases like lung inflammation caused by bacterial infection. ... -
Establishment of an experimental model for dairy cows of divergent peripartal mobilization of body reserves: Profiling circulating steroid hormones and the mRNA abundance of steroid metabolizing enzymes in liver and in adipose tissue
Schuh, Katharina (2021-12-16)The lactation cycle of dairy cows is characterized by physiological, metabolic, and endocrine changes that also affect adipose tissue (AT) function and portion. These changes include lipogenesis during periods of nutrient ... -
Expression of genes related to energy balance in adipose tissue of dairy cattle: effects of SCFA on mRNA abundance as quantified by qPCR and relevance of appropriate selection of reference genes
Hosseini, Afshin (2010-11-05)The aim of this thesis was to study the effect of propionate (C3) and β-hydroxybutyrate (BHB) on the mRNA abundance of reference genes (RGs) and of the genes of interest (GOI) related to energy balance, by short term ... -
Factorial Approach to Determining Energy and Protein Requirements of Gilthead seabream (Sparus aurata) for Optimal Efficiency of Production
Lupatsch, Ingrid (2004)Requirements for dietary energy and protein in growing fish can be quantified using the factorial approach which assumes that the requirement is the sum of growth and maintenance. Thus dietary intake can be calculated using ... -
Function and regulation of AMP-activated protein kinase in in vitro development and lipid metabolism of preimplantation bovine embryos
Prastowo, Sigit (2015-07-14)One of the major problems associated with the in vitro production of bovine embryos is lipid accumulation due to the presence of serum in culture media. AMP-activated protein kinase (AMPK) is well documented as a master ... -
Futtermittelkundliche und ernährungsphysiologische Bewertung von Rapskuchen für Milchkühe
Koch, Christian (2011-08-02)In den letzten Jahren war ein ständig zunehmender Rapsanbau in der Bundesrepublik Deutschland zu verzeichnen. Gründe hierfür waren eine erhöhte Biodieselnachfrage sowie die Nutzung von Rapsöl in der Humanernährung. Als ... -
Genetic analysis and expression study of candidate genes affecting leg weakness-related traits in pigs
Laenoi, Watchara (2011-03-09)Leg weakness (LW) problems are a great concern in the pig industry especially with regard to animal welfare. The present study was carried out to identify chromosome regions and candidate genes affecting LW-related traits ... -
Glucocorticoid receptor-mediated responses to immune stress in pigs in the context of a natural gain-of-function substitution Ala610Val
Li, Zhiwei (2022-01-07)Despite the importance of glucocorticoids (GCs) and glucocorticoid receptor (GR) signaling, relevant knowledge in pigs is scant as compared to humans and model animals. This study aims to investigate the regulation, function, ... -
Glutamindipeptid in der Ernährungstherapie von chirurgischen Patienten: metabolische und klinische Effekte nach parenteraler bzw. enteraler Supplementation
Quade, Jörg (2006)<u>Einleitung</u>: Klinische Untersuchungen zeigen, dass durch die ernährungstherapeutische Intervention mit Glutamin oder glutaminhaltigen Dipeptiden bei Patienten mit chirurgischen Interventionen, schweren thermischen ... -
Helminth antigen-induced innate immune response in porcine peripheral blood mononuclear cells
Rony, Sharmin Aqter (2017-12-21)Helminths are among the gastrointestinal parasites that are responsible for substantial loss of productivity in swine and other livestock industry. Despite indoor intensive rearing with routine anthelmintics, helminth ... -
Histomorphological and immunohistochemical characterization of different fat depots of dairy cows during early lactation
Akter, Syeda Hasina (2011-11-23)Early lactation is attended by massive fat mobilization, decreased insulin sensitivity and immunosuppression. The aim of this dissertation was to study the effects of lactation and conjugated linoleic acid (CLA) on adipocyte ... -
