    ABSTRACT: "For export only" anti-inflammatory and lightening creams are medicinal products sold in African countries for their skin whitening action. In the last years, Rapid Alerts from European Medicinal Regulatory Agencies evidenced the presence of a large number of illegal and counterfeit anti-inflammatory products advertised for their whitening action on black skin in the European market. These drugs, containing glucocorticoids, are illegally sold in Europe in unauthorized ethno-cosmetics-shops and mainly bought by immigrants. This paper reports a new RP-LC method for the rapid simultaneous screening of six different active ingredients in anti-inflammatory and whitening products (creams, ointment and suspension): betamethasone dipropionate, dexamethasone, fluocinonide, fluocinolone acetonide, clobetasol propionate, methyl-prednisolone acetate. The method was developed and validated in view of its possible application in quality control laboratories, mainly those appointed to the control of illegal/counterfeit medicinal products. The associated measurement uncertainty was calculated from validation data. The method was then applied to the analysis of whitening products obtained from the Italian illegal market.

    ABSTRACT: People often search for information on influenza A(H1N1)v prevention on the web. The extent to which information found on the Internet is consistent with recommendations issued by the World Health Organization is unknown. We conducted a search for "swine flu" accessing 3 of the most popular search engines through different proxy servers located in 4 English-speaking countries (Australia, Canada, UK, USA). We explored each site resulting from the searches, up to 4 clicks starting from the search engine page, analyzing availability of World Health Organization recommendations for swine flu prevention. Information on hand cleaning was reported on 79% of the 147 websites analyzed; staying home when sick was reported on 77.5% of the websites; disposing tissues after sneezing on 75.5% of the websites. Availability of other recommendations was lower. The probability of finding preventative recommendations consistent with World Health Organization varied by country, type of website, and search engine. Despite media coverage on H1N1 influenza, relevant information for prevention is not easily found on the web. Strategies to improve information delivery to the general public through this channel should be improved.

    ABSTRACT: The genomic structure, transcription start site, polyadenylation signals, and promoter of the human Na+/ myo-inositol cotransporter (SLC5A3) gene have been elucidated through cloning, sequencing, mRNA analyses, and reporter gene assays. The gene consists of one promoter and two exons spanning approximately 26 kb. Exon 1 contains 175 bp of 5' untranslated sequence and is 15 kb upstream of exon 2. The 9.5-kb exon 2 contains the entire 2157-bp open reading frame and a large 3' untranslated sequence with seven putative polyadenylation signals. Multiple messages with different-sized 3' untranslated regions can be detected on Northern blots. Hypertonic stress caused mRNA levels, and primarily that of the full-length 9.5-kb transcript, to increase in cultured melanoma cells; ribonuclease protection analysis demonstrated that the transcription start site was the same in stressed as in control cells. The SLC5A3 gene functions in cellular osmoregulation and is expressed in many human tissues including the brain, kidney, and placenta. It is localized to chromosome 21q22.1. An overexpression of the SLC5A3 gene deserves consideration as a factor in the pathophysiology of Down syndrome.

    ABSTRACT: Exon amplification has been applied to a 2.5 Mb region of chromosome 21 that has been associated with some features of Down syndrome (DS). Identification of the majority of genes from this region will facilitate the correlation of the over-expression of particular genes with specific phenotypes of DS. Over 100 gene fragments have been isolated from this 2.5 Mb segment. The exons have been characterized by sequence analysis, comparison with public databases and expansion to cDNA clones. Localization of the exons to chromosome 21 has been determined by hybridization to genomic Southern blots and to YAC and cosmid clones representing the region. This has resulted in a higher resolution physical map with a marker approximately every 25 kb. This integrated physical and transcript map will be valuable for fine mapping of DNA from individuals with partial aneuploidy of chromosome 21 as well as for assessing and ultimately generating a complete gene map of this segment of the genome.
