The basic premise of the paper is that Western medicine's co-opting of specific technologies and materials from other (indigenous) medical traditions, stripped of the original theories underlying their use, has problematic consequences for the practitioners and patients of both source and recipient traditions. The paper begins by illustrating the historical continuity of this process by way of an example from India's colonial era.

Thiazolidine-4-carboxylic acid (TC) is a cyclic sulfur amino acid, a condensation product of cysteine and formaldehyde. The chemistry, biological effects and clinical use of TC are reviewed. Extensive animal experiments and studies on human subjects carried out in Europe indicate that a combination of TC and folic acid, 'Folcysteine', has revitalizing effects on age-related biochemical variables of blood and tissues. Further animal studies confirmed the anti-toxic effects of TC, particularly on the liver.

Approximately 40 micronutrients are required in the human diet. Deficiency of vitamins B12, folic acid, B6, niacin, C, or E, or iron, or zinc, appears to mimic radiation in damaging DNA by causing single- and double-strand breaks, oxidative lesions, or both. The percentage of the US population that has a low intake (< 50% of the RDA) for each of these eight micronutrients ranges from 2% to > or = 20%; half of the population may be deficient in at least one of these micronutrients.

BACKGROUND: A vegetarian diet is considered to promote health and longevity and reduce the risk of cardiovascular diseases and cancer. However, a vegetarian diet may be deficient in some nutrients. Exclusion of animal products in vegetarian diets may affect the status of certain B-vitamins, and further cause the rise of plasma homocysteine concentration. OBJECTIVE: The nutritional status of various B-vitamins (B(1), B(2), B(6), B(12), folic acid) and the concentration of homocysteine in blood plasma of omnivores (n = 40), vegetarians (n = 36) and vegans (n = 42) in Austria was evaluated.

Experimental studies demonstrated that maternal exposure to certain environmental and dietary factors during early embryonic development can influence the phenotype of offspring as well as the risk of disease development at the later life. DNA methylation, an epigenetic phenomenon, has been suggested as a mechanism by which maternal nutrients affect the phenotype of their offspring in both honeybee and agouti mouse models.

In a paper in BMC Biology Virk et al. show that Caenorhabditis elegans lifespan is extended in response to a diet of folate-deficient Escherichia coli. The deficiencies in folate biosynthesis were due to an aroD mutation, or treatment of E. coli with sulfa drugs, which are mimics of the folate precursor para-aminobenzoic acid. This study suggests that pharmacological manipulation of the gut microbiome folate status may be a viable approach to slow animal aging, and raises questions about folate supplementation.

The biguanide drug metformin is widely prescribed to treat type 2 diabetes and metabolic syndrome, but its mode of action remains uncertain. Metformin also increases lifespan in Caenorhabditis elegans cocultured with Escherichia coli. This bacterium exerts complex nutritional and pathogenic effects on its nematode predator/host that impact health and aging. We report that metformin increases lifespan by altering microbial folate and methionine metabolism.

Schizophrenia, autism and depression do not inherit by Mendel's law, and the search for a genetic basis seems unsuccessful. Schizophrenia and autism relate to low birth weight and pregnancy complications, which are associated with developmental adaptations by "programming". Epigenetics might constitute the basis of programming and depend on folate status and one-carbon metabolism in general.

Addiction research focusing on homocysteine metabolism and its association with aspects of alcohol dependence has revealed important findings. Recent literature on this topic has been taken into account for the review provided. Methylenetetrahydrofolate reductase (MTHFR) is a key enzyme in the homocysteine metabolism. Plasma homocysteine levels are influenced by the single-nucleotide polymorphism (SNP) MTHFR C677T. Besides genetic factors, environmental factors have an impact on homocysteine plasma levels too.

Preterm pregnancies account for approximately 10% of the total pregnancies and are associated with low birth weight (LBW) babies. Recent studies have shown that LBW babies are at an increased risk of developing brain disorders such as cognitive dysfunction and psychiatric disorders. Maternal nutrition, particularly, micronutrients involved in one-carbon metabolism (folic acid, vitamin B(12), and docosahexaenoic acid (DHA)) have a major role during pregnancy for developing fetus and are important determinants of epigenesis.
