Introduction Bioavailability and toxicity of selenium(Se) are strongly related to the chemical form(Hartikainen, 2005).Organic Se forms are less toxic,but are significantly important in functional foods,food and feed supplements because of their increased *** is applied for the industrial production of selenium-methionine from inorganic Se(Rayman,2004).Recent interest in the field of nanotechnology has stimulated research into the chemical synthesis of Se *** on the reduction of selenite to elemental Se by sulphate reducing,Se respiring bacteria was published for first time in the 1990s(Tomeiet al.,1995).

AIm:To assess the combined effect of disease phenotype, smoking and medical therapy [steroid, azathioprine(AZA), AZA/biological therapy] on the probability of disease behavior change in a Caucasian cohort of patients with Crohn's disease(CD).mETHODS:Three hundred and forty well-characterized, unrelated, consecutive CD patients were analyzed(m/F:155/185, duration:9.4 ± 7.5 years) with a complete clinical *** records including disease phenotype according to the montreal classification, extraintestinal manifestations, use of medications and surgical events were analyzed *** were interviewed on their smoking habits at the time of diagnosis and during the regular follow-up ***:A change in disease behavior was observed in 30.8% of patients with an initially non-stricturing, non-penetrating disease behavior after a mean diseaseduration of 9.0 ± 7.2 *** a logistic regression analysis corrected for disease duration, perianal disease, smoking, steroid use, early AZA or AZA/ biological therapy use were independent predictors of disease behavior *** a subsequent Kaplan-meier survival analysis and a proportional Cox regression analysis, disease location(P = 0.001), presence of perianal disease(P moking(P = 0.032) were independent predictors of disease behavior ***:Our data suggest that perianal disease, small bowel disease, smoking, prior steroid use, early AZA or AZA/biological therapy are all predictors of disease behavior change in CD patients.

There is evidence that a substantial part of genetic predisposition to prostate cancer (PCa) may be due to lower penetrance genes which are found by genome-wide association studies. We have recently conducted such a study and seven new regions of the genome linked to PCa risk have been identified. Three of these loci contain candidate susceptibility genes: mSmB, LmTK2 and KLK2/3. The mSmB and KLK2/3 genes may be useful for PCa screening, and the LmTK2 gene might provide a potential therapeutic target. Together with results from other groups, there are now 23 germline genetic variants which have been reported. These results have the potential to be developed into a genetic test. However, we consider that marketing of tests to the public is premature, as PCa risk can not be evaluated fully at this stage and the appropriate screening protocols need to be developed. Follow-up validation studies, as well as studies to explore the psychological implications of genetic profile testing, will be vital prior to roll out into healthcare.
