MicroRNAs in the bovine ovary and placentas derived from in vivo, in vitro and nuclear transfer pregnancies
(2010-12-15)
MicroRNAs are the major class of gene regulating molecules playing pivotal roles at post-transcriptional level. Identification and expression profiling are the initial steps to understand their regulation of biological ...
The oscillatory mechanisms of working memory maintenance
(2016-06-14)
Working memory (WM) is a cognitive process which allows for maintenance of information that is no longer perceived. Although theoretical models have recognized that working memory involves interactions across cell assemblies ...
Oxytocin – the prosocial molecule?: Intranasal oxytocin effects on social approach behavior, social cognition, volitional and emotional ambivalence in healthy human beings
(2015-10-30)
Oxytocin (OXT) is a highly conserved neuropeptide, regarding both its chemical structure and its functionality. It has been traced back at least 700 million years. OXT’s fundamental role lies in reproduction and parenting ...
Epigenetic regulation of CD14 in TRIF pathway in pulmonary alveolar macrophages of German Landrace pigs
(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. ...
Ultrastructure, Formation and Evolution of Chaetae in Annelids
(2016-02-02)
Annelid systematics has been quite unstable over the past century. Especially, with the introduction of molecular techniques to unravel phylogenetic relationships, previously established morphology-based phylogenetic trees ...
Wahrnehmung von Wirbelstraßen bei Fischen der Familien Cyprinidae und Salmonidae
(2013-01-10)
In der vorliegenden Arbeit wurden erstmals Fische aus unterschiedlichen Lebensräumen auf komplexe hydrodynamische Reize im Fließwasser konditioniert. Hierzu wurden Kármánsche Wirbelstraßen verschiedener Wirbelablösefrequenzen ...

Complement-mediated neuronal loss by sialic acid glycocalyx alterations
(2018-04-23)
Every neuronal cell is covered with a dense structure of glycoconjugates, the glycocalyx. Sialic acids form the terminal ends of the glycocalyx and thus, are more accessible for the cellular environment. Microglia, the ...
