Analysis of the types of protein adducts formed by chemical carcinogens indicate that adducts may be categorized into various classes according to the nature of the carcinogen as well as the amino acid with which they react. Tryptophan(214) of serum albumin was previously shown to react specifically with N-sulfonyloxy-N-acetyl-4-aminobiphenyl. The same residue is now shown to also react with th...

In protein structure space, protein structures cluster into four elongated regions when mapped based solely on similarity among the 3D structures. These four regions correspond to the four major classes of present-day proteins defined by the contents of secondary structure types and their topological arrangement. Evolution of and restriction to these four classes suggest that, in most cases, th...

Several classes of protein may undergo non-enzymetic addition of glucose derived product. Hemoglobin was the first protein shown to be modified. Subsequent studies have demonstrated a similar effect of glucose on lens crystalline, collagen, erythrocyte membrane proteins, albumin and other serum proteins. Measurement of these non-enzymatic glycosylated serum proteins (GSP) showed that the l...

The purpose of this literature review was to identify and describe recent empirical studies of childbirth education outcomes and to identify areas for further study. The search produced 63 studies; only 12 met the inclusion criteria. The literature demonstrated inconclusive evidence regarding the effectiveness of childbirth education. None of the studies used a theoretical framework that propos...
