Disordered Porphyrin Metabolism: A Potential Biological Marker for Autism Risk Assessment

A potential new biological marker of the biological age

between the nature of the brain damage in the aging process (in the case of dementia or even in outwardly healthy elderly people) and the brain damage caused by prion diseases of humans and animals (Sobel, 1970; Fraser and McBride, 1985; Masters et al., 1985; Gajdusek, 1988). In both cases, lesions are characterized by the two fundamental processes—the loss of neurons and an active proliferatio...

Porphyrin Metabolism

The suggestion of Duesberg (1) that prolonged ingestion of allylisopropylacetylcarbamide (Sedormid)’ may have induced acute porphyria in a human led later workers to produce this disorder in rabbits (2) and rats (3) by oral administration of the drug. Although this experimental procedure has facilitated the study of acute porphyria, the possibility remains that some of the porphyrin excreted in...

The potential usefulness of biological markers in risk assessment.

Substantial data have been generated during the last 5 years in experimental systems and human populations which shed light on the potential usefulness of biological markers in human cancer risk assessment. Following a brief review of overall progress to date in the biomonitoring of human populations, this paper turns to the growing body of data regarding carcinogen-DNA and protein adducts as i...

Lipoprotein(a): A Promising Marker for Residual Cardiovascular Risk Assessment

Atherosclerotic cardiovascular diseases (CVD) are still the leading cause of morbidity and mortality worldwide, although optimal medical therapy has been prescribed for primary and secondary preventions. Residual cardiovascular risk for some population groups is still considerably high although target low density lipoprotein-cholesterol (LDL-C) level has been achieved. During the past few decad...
