Molds and mycotoxins in indoor environments--a survey in water-damaged buildings.

30 Oct 2009 Mycotoxins are toxic, secondary metabolites frequently produced by molds in water-damaged indoor environments. We studied the prevalence of selected, potent mycotoxins and levels of fungal biomass in samples collected from water-damaged indoor ... Read more...

Branch-specific sialylation of IgG-Fc glycans by ST6Gal-I.

18 Oct 2009 Sialylated forms of the Fc fragment of immunoglobulin G, produced by the human alpha2-6 sialyltransferase ST6Gal-I, were identified as potent anti-inflammatory mediators in a mouse model of rheumatoid arthritis and are potentially the active ... Read more...

The cis-(5R,6S)-thymine glycol lesion occupies the wobble position when mismatched with deoxyguanosine in DNA.

18 Oct 2009 Oxidative damage to 5-methylcytosine in DNA, followed by deamination, yields thymine glycol (Tg), 5,6-dihydroxy-5,6-dihydrothymine, mispaired with deoxyguanosine. The structure of the 5R Tg.G mismatch pair has been refined using a combination of ... Read more...
