Left-sided displacement of the abomasum (LDA) is an economically important disease in Holstein dairy cattle populations all over the world. The bovine abomasum is the equivalent to the stomach in monogastric species and its pathologic displacement is usually preceded by bloating due to reduced gastrointestinal contractions.
Over the past 50 years, the incidence of LDA has considerably increased. Despite surgical veterinary treatments, LDA affected cows show a long convalescence.
Scientists of the Institute for Animal Breeding and Genetics at the University of Veterinary Medicine Hannover Foundation in cooperation with the clinic for cattle of Hannover and the Clinic for Ruminants and Swine, Faculty for Veterinary Medicine at the Justus-Liebig-University Giessen, sequenced the complete motilin gene in German Holstein cows.
They identified a single nucleotide polymorphism showing significant association with LDA and affecting a transcription factor binding site. An expression study gave evidence of a significantly decreased motilin expression in cows carrying the mutant allele. The study indicates motilin to be involved in the etiopathogenesis of LDA in German Holstein cattle.It provides a first step towards the understanding of the genetics of LDA and may be of use for investigating gastric motility disorders in other species.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
