Bioengineering

Bioengineering can be defined as the alteration of the gene expression of any biological organism by molecular methodologies. Bioengineering in any metabolic pathway requires that all steps within the pathway be defined, the regulatory points identified, and the stability of the intermediates determined Scott et al., 2000 . Phytochemicals are often differentially expressed both spatially and temporally. For example, the concentration of alkamides differs among plant organs in Echinacea purpurea...

Clinical Studies

A highly publicized study examined the effect of cranberry juice cocktail on bac-teriuria and pyuria in 153 elderly women Avorn et al., 1994 . By the second month of the study, the placebo group had three times the number of bacteria-contaminated urine samples as the cranberry group. Although the differences varied with time, the differences between groups became smaller after 6 months. Some patients in each group 16, placebo 8, cranberry were treated with antibiotics for UTIs during the course...

Complexities In The Existing Literature

The data discussed in this chapter suggest that dietary intake of soy protein including the isoflavones, has health benefits in the primate brain that may protect against AD-relevant protein modifications involving the microtubule protein tau. Thus, these data suggest that incorporating soy containing isoflavones into human diets may be neuroprotective. Yet scientific data are never perfect, and in this relatively new area of research on the effects of soy in the nervous system, the data are...

Conclusion

HMPs can be powerful medications which may cause both benefit and harm. In order to embark on reliable risk-benefit analyses, we need to know more about their clinical efficacy and about their adverse effects. An evidence-based approach to medical herbalism seems to be the most rational way ahead. This notion is in agreement with the opinion of 88 to 90 of users of HMPs who state that research into the safety and efficacy determines their product choice Blumenthal, 2000 . Increased effect of...
