Towards messages that matter: Understanding and addressing HIV and SRH risks among married young people in India

Although there is increasing interest in young people\u27s sexual and reproductive health (SRH) situations and needs in India, married young people have received little attention as a vulnerable group with distinct needs because marriage is assumed to be safe and because married youth are assumed to face none of the stigma that their unmarried counterparts experience in accessing SRH services. However, emerging evidence shows that within this subpopulation, married young women and men constitute groups with distinct risks of HIV and other poor SRH outcomes. There remains a need to better understand their unique vulnerabilities and to design programs that take into account their special circumstances. The Population Council and the Family Planning Association of India undertook a research project intended to better understand the situation and vulnerabilities faced by married young women and men, and to develop communication materials for married young women and men and training materials for providers to address HIV and other SRH risks experienced by these subpopulations. The study was conducted in rural settings in Guntur district of Andhra Pradesh, and in Dhar and Guna districts of Madhya Pradesh

Esterases as Genetic Markers in Finger Millet

Different varieties of finger millet (Eleusine coracana Gaertn.) were screened for esterase activity colorimetrically and electrophoretically using 1-naphthyl acetate and acetylthiocholine chloride as substrates. The Indian brown seed coat variety (Purna), the Indian white seed coat variety (Hamsa), hybrids of these designated as HPB (brown) and HPW (white), African varieties (brown) and Indian-African hybrid varieties (brown) all exhibited 1-naphthyl acetate hydrolysing activity and showed 6,5,6,5,8 and 8 esterolytic bands respectively on gel electrophoresis. The white seed coat varieties, both parental (Hamsa) and hybrid (HPW), did not possess any acetylthiocholine chloride hydrolysing activity while all the brown seed coat varieties did, the African varieties having greater activities than Indian brown seed coat varieties. Thus, the demonstrable variation in esterase isozymic pattern and cholinester hydrolysing activity with the varieties tested provides a useful genetic marker for identifying different varieties of finger millet

Good optical transparency is not an essential requirement for effective solar water disinfection (SODIS) containers

The efficacy of 10 L polypropylene (PP) transparent jerry cans (TJCs) to inactivate E. coli, MS2-phage and Cryptosporidium parvum via solar water disinfection (SODIS) was tested in well water or general test water under natural sunlight. Food-safe PP was used to manufacture the TJCs and a clarifying agent was added to improve optical transparency in the UV–visible range. 10 L PP TJCs and 2 L polyethylene terephthalate (PET) bottles were filled with well water, spiked separately with (~106 CFU/mL of E. coli, ~106 PFU/mL of MS2 phage and 5 ×105C. parvum oocysts per litre) and exposed to natural sunlight for 6 h. While the 10 L PP TJC prototype had poorer transparency (UV-B 0.001%, UV-A 4.29%, and visible 92% for TJCs without clarifier and UV-B 1.36%,UV-A 8.01%, and visible 90.01% for TJCs with clarifier) than standard 2 L PET (UV-B 0.72%, UV-A 10–85%, and visible 80–90%); log reduction values (LRVs) > 5, 2 and 0.8 for E. coli, MS2-phage, and C. parvum, respectively, were observed for the TJCs within six hours respectively, which is a minimum standard for drinking water established by the World Health Organisation (WHO). We observed similar inactivation kinetics for all three organisms in PP TJCs and PET bottles despite the poorer optical transparency properties of the SODIS jerry cans. Therefore, for effective SODIS, container optical transparency is not as important as previously believed. We conclude that good visible transparency is not a necessary requirement for containers intended for SODIS use
