Functional analysis of microRNA-130b in bovine oocyte maturation and preimplantation embryo development
(2011-08-09)
MicroRNAs (miRNAs) are well known to regulate the proteins involved in various biological processes including development. The expression pattern of miRNAs is believed to vary between immature and in vitro matured bovine ...
Nitrogen management in irrigated cotton-based systems under conservation agriculture on salt-affected lands of Uzbekistan
(2011-11-23)
Intensive soil tillage and mismanagement of irrigation water and fertilizers reduce soil organic matter and increase secondary soil salinization. These processes are increasing production costs, reducing soil fertility and ...
Pesticide Use and Management in the Mekong Delta and their Residues in Surface and Drinking Water
(2011-11-29)
Pesticides are essential inputs in agricultural production to control target pests and thus to improve crop yields. Appropriate use and management of these chemicals and reduction of its negative influences on human health ...
Impacts of European biofuel policies on global biofuel and agricultural markets
(2011-10-13)
The strong increase of global biofuel markets within the last years has led to a continuous increase of biofuel feedstock demand. Due to the current state of biofuel production technologies primarily traditional agricultural ...
Ruminal degradation of ochratoxin A – in vitro investigations at varying rations and rumen microbial populations
(2011-11-15)
The primary objective of the present study was to evaluate the relative contribution of different rumen microbial populations (MP) and the effect of ration on degradation of ochratoxin A (OTA), gas, short chain fatty acids ......

Effect of maternal dietary supplementation of one-carbon-cycle substrates and co-factors during gestation on hepatic gene expression in pigs at different developmental stages
(2011-10-19)
German Landrace (DL) and Pietrain (PI) sows were fed either a gestation diet supplemented with substractes and co-factors of the one-carbon-cycle ('MET') or a control ('CON') gestation diet. Fetal liver tissue of day 35, ...
Monitoring of Endocrine Disruptors in Surface Waters of the Mekong Delta in Vietnam
(2011-12-01)
This study monitors estrogenic-Endocrine Disruptors (e-EDs) in surface waters in the Mekong Delta in Vietnam, one of the most populated agricultural areas in the world. e-ED is a subclass of Endocrine Disruptors (EDs), ...
Determination of Sub-daily Earth Rotation Parameters from VLBI Observations
(2011-11-16)
The work presented deals with the determination of sub-daily Earth Rotation Parameters (ERPs) from Very Long Baseline Interferometry (VLBI) observations. Monitoring and interpreting the Earth's rotation variations in general ...
Histomorphological and immunohistochemical characterization of different fat depots of dairy cows during early lactation
(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 ...
Investigation on host-parasite interaction between the stem nematode Ditylenchus dipsaci and sugar beet Beta vulgaris and their importance for development of alternative integrated management strategies
(2011-11-16)
The re-occurrence and rapid spread of D. dipaci in German sugar beet production areas enhanced the necessity for a holistic management strategy of this pathogen to secure sustainable sugar production.
