(2010-09-16)`Congenital Disorders of Glycosylation` (CDG) are a rapidly expanding group of so far 23 autosomal recessive multisystemic disorders associated with deficiencies in the biosynthesis of ... -
Metagenomanalysen von zwei Habitaten mit (hemi-)cellulolytischen mikrobiellen Gemeinschaften
(2010-06-04)The analysis of metagenomes not only can give an insight into the microbial diversity of a habitat, it can also reveal new biocatalysts by screening of metagenomic DNA-libraries. In the ... -
Auswirkungen der Deletion membranständiger Dehydrogenasen auf Gluconobacter oxydans DSM 7145
(2009-11-06)Gluconobacter oxydans is one of the most important organisms in industrial biotechnology because of its ability to incompletely oxidize various sugars, sugar alcohols and sugar acids. The ... -
Aktivität endogener Retroviren in Tumorgeweben von Primaten
(2009-09-14)The human endogenous retroviruses of the family K (HERV-K) is an evolutionary young group of retroviral sequences. In comparison with other endogenous retroviruses, some HERV-K proviruses ... -
Regulation of nitrogen fixation in <i>Klebsiella pneumoniae</i>: Nitrogen and oxygen signal perception by the negative regulator NifL
(2008-08-08)In the diazotroph Klebsiella pneumoniae, the nif specific transcriptional activator NifA is inhibited by the flavoprotein NifL in response to molecular oxygen and ammonium. We demonstrated ... -
Untersuchung der Stressantwort von <i>Picrophilus torridus</i> mittels 2D-Gelelektrophorese und Charakterisierung ausgewählter Dehydrogenase
(2008-07-09)The thermoacidophilic archaeon Picrophilus torridus belongs to the Thermoplasmatales and is the most acidophilic microbe yet known. Optimal living conditions are at 60°C and pH 0.7. Some ... -
Untersuchung zur wechselseitigen Beeinflussung von Chemotaxinen und Dendritischen Zellen
(2008-04-01)Prostaglandin (PG) E2 and IL-4 have been implicated in maturation of DC and in the modulation of DC migration. In the present study, IL-4 as well as IL-13 were found to impair migration of murine DC and macrophages in ... -
Herstellung und Charakterisierung monoklonaler Antikörper gegen die Anaphylatoxin-Rezeptoren
(2008-01-29)Anaphylatoxins are potent pro-inflammatory mediators that induce their biological effects through high affinity binding to specific cellular receptors. Due to controversial evidence in the ... -
Blue light-dependent development of the filamentous fungus Aspergillus nidulans
(2007-11-22)Numerous studies have revealed that fungal development and the production of secondary metabolites are linked although the molecular mechanisms are yet unknown. Light seems to be one of the ... -
Identification and characterization of Campylobacter jejuni factors relevant for the infection process
(2007-10-09)Campylobacter jejuni is the most frequent bacterial cause of foodborne-illness in the developed world including Germany, where the reported number is 60,000 cases in a year. Despite the ... -
Metagenombasierte Isolierung und biochemische Charakterisierung neuartiger stereospezifischer Lipasen für biokatalytische Anwendungen
(2007-08-31)The technique of cloning DNA from a certain habitate, the so called metagenome contributed in the last years successfully to the accession of the genetic potential of all present ... -
Übertragung von BSE auf nicht humane Primaten als Modell für die variante Creutzfeldt-Jakob Erkrankung (vCJD) im Menschen
(2007-06-05)The EU-study QLK1-CT-2002-01096 was designed to assess the risk of vCJD (variant Creutzfeldt-Jakob disease) infection in humans via BSE-contaminated food in an animal model. Groups of six ... -
