“Ignorance is not Innocence”: The Social Health Association of Indiana and Adolescent Sex Education, 1907-2007

“Ignorance is not innocence,” thundered John Hurty Secretary of the Indiana Board of Health in 1913 attempting to persuade his colleagues that only “sex knowledge” could prevent the problem of adolescent venereal disease. Throughout the twentieth century, Hurty and other Indiana reformers took the lead in national efforts to raise public awareness of the dangers of sexually transmitted diseases as part of larger debates on how to educate adolescents on the dangers of sexual activity prior to marriage This project, funded in part by the IUPUI Solution Center and Social Health Association of Indiana (SHA), seeks to use various public history methodologies to illustrate the important role Indiana played in the history of adolescent sexuality education. The history of the Social Health Association of Indiana (SHA) reflects changes not only in the sexuality education movement, but also in the broader context of adolescent sexuality, educational reform and public health movements. This project is an example of the IUPUI’s Public History Master’s program training that blends theory and hands-on experience specific to public history, often in partnership with community organizations. Today, the SHA continues their 100 year tradition of “foster successful lives by empowering youth to make responsible choices and adopt healthy behaviors.

Development and comparison of two multiresidue methods for the determination of 17 Aspergillus and Fusarium mycotoxins in cereals using HPLC-ESI-TQ-MS/MS

Cereals can be contaminated by several mycotoxins, whose co-presence may represent an undervalued risk for humans and animals. Maize and wheat are the most contaminated cereals and in temperate areas could be affected in field conditions by several Fusarium and Aspergillus infections. To date, only B-fumonisins (FBs), aflatoxins (AFs), zearalenone (ZEA), deoxynivalenol (DON) and T-2 and HT-2 toxins have been regulated in cereals in European Union. The other fungal metabolites, are commonly referred to as “emerging” and “masked” mycotoxins, and more information on their occurrence in combination with the regulated mycotoxins, are needed to design combined toxicological and exposure assessments.This research intends to develop and compare two multiresidue HPLC-ESI-TQ-MS/MS methods for the simultaneous determination of the main regulated, emerging and masked mycotoxins in maize and wheat, among which: FB1, FB2, DON, ZEA, AFB1, AFB2, AFG1, AFG2, moniliformin (MON), deoxynivalenol-3-glucoside (DON-3-G), 3-acetyldeoxynivalenol (3-ADON), 15-acetyldeoxynivalenol (15-ADON), nivalenol (NIV), enniatins A, A1, B, B1 (ENNA, ENNA1, ENNB, ENNB1). The extraction was performed for both methods using a mixture of CH3CN/H2O/CH3COOH (79/20/1, v/v/v), while the dilution/purification was carried out through two different procedures: (1) by the “dilute-and-shoot” technique diluting 1:2 the filtered extract with CH3CN/H2O/CH3COOH (20/79/1, v/v/v) to reduce the matrix effect; (2) using the Oasis® PRiME HLB clean-up columns. The analysis was carried out using CH3OH and H2O both acidified with 0.1% of CH3COOH as eluents. The injection volume was 20 μL and the flow rate 200 μL min-1. The analysis of two reference material (maize and wheat), was performed to evaluate the trueness and precision of the two methods by matrix-matched calibration curves. For all the regulated mycotoxins analyzed by both methods, the range of recovery percentage established by the Regulation (EC) No. 401/2006 was respected, except for ZEA by using the Oasis® PRiME HLB clean-up columns. Nevertheless, the results suggest that the Oasis® PRiME HLB clean-up columns, could be a valid alternative to the dilute-and-shoot method, although an additional cost for the clean-up has to be considered. In conclusion, both two analytical methods considerably reduce the analytical time and costs and therefore result to be promising and applicable for high-throughput routine multi-mycotoxins analysis by the use of a TQ
