Specific IgE to proteins from Tribolium confusum (TC), a flour beetle, was detected in 9/125 sera of subjects exposed to rye and wheat flour. TC RAST was not inhibited by Dermatophagoides pteronyssinus, rye or wheat flour. Immunoblot experiments showed specific binding to three proteins from adult TC or pupae, not present in rye or wheat flour. These findings suggest that TC might act as an occ...

On October 19, 1901, Dr R.C. Harris, a St Louis physician, attended to a young girl named Bessie Baker who was suffering from advanced diphtheria. As was his routine, he injected diphtheria antitoxin into the child and, as a preventive, her 2 younger siblings and concluded that “she would soon be entirely well.” But 4 days later he was called back to the Bakers’ home to a terrifying discovery:

Dihydrouridine residues in bakers’ yeast transfer RNA were reductively cleaved with sodium borohydride. The amino acid acceptor activity of three species of transfer RNA and the ribosoma binding of one species of transfer RNA were determined for these modified transfer RNAs. The data indicate that the reductive cleavage of the dihydrouridine residues in these transfer RNAs has no effect upon th...

ATP is the universal energy substance of all living cells. F1F0-ATP synthase, a multisubunit enzyme found in bacteria, chloroplasts and mitochondria, is responsible for the synthesis of ATP and thus provides energy to almost all living cells. Our research is focused on the mitochondrial complex (mtATPase) of bakers’ yeast Saccharomyces cerevisiae (Fig. 1). Yeast provides a powerful system in wh...
