1. 3Hand 35S-labelled heparan sulphate was isolated from monolayers of human lung fibroblasts and subjected to degradations by (a) deaminative cleavage and (b) periodate oxidation/alkaline elimination. Fragments were resolved by geland ion-exchangechromatography. 2. Deaminative cleavage of the radioactive glycan afforded mainly disaccharides with a low content of ester-sulphate and free sulphat...

Infection with the helminth parasite Schistosoma mansoni induces a pronounced Th2-type response that is associated with significant IgE production. To better understand how the parasite drives these responses, we investigated the relative roles of proteins and carbohydrates in driving Th2-type and/or IgE responses using a murine model of intranasal sensitization with soluble egg Ags (SEA) of Sc...

Sustainable Chemistry The cover image for article number 2100391 by Siegfried R. Waldvogel and co-workers represents a method to obtain selectively 5-iodovanillin, as an advanced building block, from side-stream lignins degradation using electrochemically generated periodate. In times of climate changes the utilization lignin renewable feedstock fine chemicals is considered, would rival petrole...

The complement system is important for host resistance to hematogenously disseminated candidiasis. However, modulation of complement activation by cell wall components of Candida albicans has not been characterized. Although intact yeast display mannan on the surface, glucan, typically located in the interior, becomes exposed during C. albicans infection. We show here the distinct effects of ma...

We have determined the effect of various endocytic ligands on the secretion of ApoE by macrophages. ApoE was a major secreted protein of resident macrophages, but BCG-activated macrophages secreted little ApoE and periodate-elicited macrophages secreted intermediate amounts of ApoE. Resident, periodate-elicited, and BCG-activated mouse peritoneal macrophages were incubated with AcLDL, EIgG, EIg...

MicroRNAs (miRNAs) ubiquitously exist in microorganisms, plants, and animals, and appear to modulate a wide range of critical biological processes. However, no definitive conclusion has been reached regarding the uptake of exogenous dietary small RNAs into mammalian circulation and organs and cross-kingdom regulation. One of the critical issues is our ability to assess and distinguish the origi...

Ferroelectric thin-films are highly desirable for their applications on energy conversion, data storage and so on. Molecular ferroelectrics had been expected to be a better candidate compared to conventional ferroelectric ceramics, due to its simple and low-cost film-processability. However, most molecular ferroelectrics are mono-polar-axial, and the polar axes of the entire thin-film must be w...
