INTRODUCTION: Reductions in the prevalence of hepatitis B virus (HBV) infection and carriage, decreases in liver cancer incidence, and changes in patterns of liver dysfunctions are described after hepatitis B vaccination. METHODS: We conducted a population-based seroprevalence study aimed at estimating the HBV prevalence and risk of infection in the rural area of Lábrea following nineteen years of HBV vaccination. RESULTS: Half of the subjects showed total anti-HBc of 52.1% (95% CI 49.6-54.7). The HBsAg prevalence was 6.2% (95% CI 5.1-7.6). Multivariate analysis showed an inverse association between HBV infection and vaccination (OR 0.62; 95% CI 0.44-0.87). HBsAg remained independently associated with past hepatitis (OR 2.44; 95% CI 1.52-3.89) and inversely to vaccination (OR 0.43; 95% CI 0.27-0.69). The prevalence of HBeAg among HBsAg-positive individuals was 20.4% (95% CI 12.8-30.1), with the positive subjects having a median age of 11 years (1-46) p=0.0003. CONCLUSIONS: We demonstrate that HBV infection is still an important public health issue and that HBV vaccination could have had better impact on HBV epidemiology. If we extrapolate these findings to other rural areas in the Brazilian Amazon, we can predict that the sources of chronic infected patients remain a challenge. Future studies are needed regarding clinical aspects, molecular epidemiology, surveillance of acute cases, and risk groups.

The identification of all human chromosome 21 (HC21) genes is a necessary step in understanding the molecular pathogenesis of trisomy 21 (Down syndrome). The first analysis of the sequence of 21q included 127 previously characterized genes and predicted an additional 98 novel anonymous genes. Recently we evaluated the quality of this annotation by characterizing a set of HC21 open reading frames (C21orfs) identified by mapping spliced expressed sequence tags (ESTs) and predicted genes (PREDs), identified only in silico. This study underscored the limitations of in silico-only gene prediction, as many PREDs were incorrectly predicted. To refine the HC21 annotation, we have developed a reliable algorithm to extract and stringently map sequences that contain bona fide 3' transcript ends to the genome. We then created a specific 21q graphical display allowing an integrated view of the data that incorporates new ESTs as well as features such as CpG islands, repeats, and gene predictions. Using these tools we identified 27 new putative genes. To validate these, we sequenced previously cloned cDNAs and carried out RT-PCR, 5'- and 3'-RACE procedures, and comparative mapping. These approaches substantiated 19 new transcripts, thus increasing the HC21 gene count by 9.5%. These transcripts were likely not previously identified because they are small and encode small proteins. We also identified four transcriptional units that are spliced but contain no obvious open reading frame. The HC21 data presented here further emphasize that current gene prediction algorithms miss a substantial number of transcripts that nevertheless can be identified using a combination of experimental approaches and multiple refined algorithms.

This book is the address delivered at Iowa City, Iowa, before the State Historical Society of Iowa on May 25, 1910 by Laenas Gifford Weld. His speech covers the history and the discovery of the territory of the Mississippi Valley and Iowa. He talks about early pioneers and explorers, the routes they took and how they navigated into this newly discovered territory.

Allylnitrile, cis-crotononitrile, and 3,3 -iminodipropionitrile are known to cause vestibular toxicity in rodents, and evidence is available indicating that cis-2-pentenenitrile shares this effect. We evaluated nineteen nitriles for vestibular toxicity in wild type (129S1) and CYP2E1-null mice, including all the above, several neurotoxic nitriles, and structurally similar nitriles. A new acute toxicity test protocol was developed to facilitate evaluation of the vestibular toxicity by a specific behavioral test battery at doses up to sub-lethal levels while using a limited number of animals. A mean number of 8.5±0.3 animals per nitrile, strain and sex was necessary to obtain evidence of vestibular toxicity and optionally an estimation of the lethal dose. For several but not all nitriles, lethal doses significantly increased in CYP2E1-null mice. The protocol revealed the vestibular toxicity of five nitriles, including previously identified ototoxic compounds and one nitrile (trans-crotononitrile) known to have a different profile of neurotoxic effects in the rat. In all five cases, both sexes were affected and no decrease in susceptibility was apparent in CYP2E1-null mice respect to 129S1 mice. Fourteen nitriles caused no vestibular toxicity, including six nitriles tested in CYP2E1-null mice at doses significantly larger than the maximal doses that can be tested in wild type animals. We conclude that only a subset of low molecular weight nitriles is toxic to the vestibular system, that species-dependent differences exist in this vestibular toxicity, and that CYP2E1-mediated metabolism is not involved in this effect of nitriles although it has a role in the acute lethality of some of these compounds

Tutkielmani aiheena on dystooppisen kirjallisuuden tunnetuin teos, George Orwellin Nineteen Eighty-Four (1949), ja erityisesti sen tarkoitusperien vastaavuus nykymaailman kanssa. Avoimen poliittisen kirjailijan tavoite läpi uran oli mobilisoida kansalaisia haastamaan heitä hallitsevia voimia. Viimeisessä ja uransa huipentumaksi jääneessä romaanissaan Orwell maalaa lohduttoman ääriesimerkin lähitulevaisuuteen sijoitetusta totalitaristisesta maailmasta, jossa ihmisyydellä ei ole enää sijaa. Teoksesta on muodostunut käytetyin esimerkki puhuttaessa negatiivisista tulevaisuudenvisioista. Työni jakautuu kahteen päälukuun, joista ensimmäisessä tutkin romaanin käsitystä siitä, kuinka kieltä manipuloimalla (Newspeak) voidaan vaikuttaa myös ajatteluun (Doublethink), todellisuuden kokemiseen ja historian muistamiseen, sekä romaanista nykykieleen jääneitä sanoja ja termejä. Toisessa pääluvussa pohdin kirjailijan varsinaista kritiikin kohdetta totalitarismia, kuinka se on romaaniin rakennettu, millaista sen valta on, ja millaiset ihmiset siihen suostuvat. Lopuksi tarkastelen, kuinka romaani aikanaan otettiin vastaan ja miten sitä yhä (hyväksi)käytetään. Pääpainotus tutkielmassani on pääteemojen kytkeminen niiden konkreettisiin ja mentaalisiin vaikutuksiin reaalimaailmassa. Orwell oli huolissaan erityisesti poliittisen kielen turmelevasta vaikutuksesta, joten pohdin, mitä ovat nykyajan uuskieli ja kaksoisajattelu sekä millaisia seurauksia kielen manipuloinnilla on. Usein utopioita ja dystopioita arvostetaan virheellisesti niiden toteutuneiden yksityiskohtien kautta, ja siksi yritän selvittää, miltä osin ja millaisena dystopia ylipäänsä voi mielekkäästi toteutua. Missä suhteessa Orwell oli ”oikeassa” tai ”väärässä” laajassa, ei-triviaalissa mielessä? Mitä hänen teoksensa tarjoaa 2000-luvun lukijalle? Perusteesini on, että tavallisen varoitukseksi tai profetiaksi tulkitsemisen sijaan romaani on satiiri, jollaisena kirjailija itsekin sitä piti. Samalla todistan, että läpitunkeva valvontayhteiskunta, joka on samalla romaanin tunnetuin puoli ja jota termi orwellian nykyään kuvaa, on itse asiassa vain illuusio. Uutta näkökulmaa romaanin tulkintaperinteeseen tuon näyttämällä, kuinka ääripessimistisenä pidettyyn tekstiin on huolellisesti piilotettu toiveikkuutta, jolla kirjailija on halunnut herätellä kansalaisia, jotka ovat piittaamattomia tai tietämättömiä heidän elämäänsä kontrolloivista voimista. Yritän tutkielmassani osoittaa, kuinka vaikea on kuvitella sellaista yhteiskuntaa, jossa Nineteen Eighty-Four ei olisi jollain tavalla ajankohtainen.
