Erweiterung der Peptidligation auf Saure pH‐Bereiche und Schnittstellen mit Glykosylierten und Phosphorylierten Aminosäuren

open access: yesAngewandte Chemie, EarlyView.
Ein pyridinhaltiges Ligationsauxiliar beseitigt einen wesentlichen Engpass der Peptidligationschemie. Der für die Ligation nutzbare pH‐Bereich von 2,0–7,5 hilft, Epimerisierung zu vermeiden. Die native chemische Ligation (NCL) verläuft an praktisch jeder Ligationsstelle, einschließlich Reaktionen an β‐verzweigten sowie O‑glykosylierten oder O ...

Mucin stimulates the growth of Legionella pneumophila

open access: yes
Previously, it was demonstrated that a chitinase (ChiA) secreted by the Legionella pneumophila type II secretion system (T2SS) degrades mucin, thereby facilitating bacterial movement through a mucin layer.

Extending Peptide Ligation to Acidic pH and Junctions Comprising Glycosylated and Phosphorylated Amino Acids

open access: yesAngewandte Chemie International Edition, EarlyView.
A pyridine‐containing ligation auxiliary eliminates a major bottleneck of peptide ligation chemistry. The extended range of applicable pH values (2.0–7.5) in the ligation reaction helps to avoid epimerization. Native chemical ligation (NCL) proceeds at virtually any junction, including reactions at β‐branched amino acids, as well as O‐glycosylated or O‐

A constituent of human small intestinal mucus that copurifies with mucin and can interfere with raising antibodies to the mucin

open access: yes, 1994
The accuracy of an immunoassay for mucin depends on the antibodies' specificity. During human small intestinal mucin purification on a CsCl gradient, a very antigenic non-mucin contaminant was found at 1.48 g.ml -1 density.

Innervation of the tubarial glands: A hypothesis‐driven anatomical review

open access: yesThe Anatomical Record, EarlyView.
Abstract The tubarial glands have been described as a macroscopic bilateral glandular complex in the posterolateral nasopharynx near the torus tubarius and the pharyngeal opening of the Eustachian tube. Since their recognition on prostate‐specific membrane antigen‐based imaging, their anatomical classification has remained debated, with converging ...

Comparative histological, histochemical, and histometric evaluation of the esophagus in two avian species with different feeding habits (Ciconia ciconia and Buteo buteo)

open access: yesThe Anatomical Record, EarlyView.
Histological structure of esophagus. Abstract The aim of this study was to conduct a comparative evaluation of the histological and histochemical organization of the esophagus in two avian species with different feeding ecologies. A total of 6 individuals were used for this purpose (3 storks, 3 common buzzards).

Morphological description of the oropharyngeal cavity of Kinosternon scorpioides scorpioides (Linnaeus, 1766), (Testudines: Kinosternidae)

open access: yesThe Anatomical Record, EarlyView.
Gross morphology, Light Microscopy and Scanning Electron Microscopy revealed the structural organization of the oropharyngeal cavity of Kinosternon scorpioides scorpioides, characterized by mucous epithelium, epithelial pores, and developed lingual papillae.
