1. Correspondencia: Carlos Madrid - Service Stomatologie; Médecine Dentaire; Policlinique Médicale Universitaire; Recibido Aceptado
Un varón de 53 años fue remitido con una historia clínica de neuropatía sensitiva periférica y de enfermedad de Raynaud, por sospechar un síndrome de Sjögren (SS). La biopsia de glán-dulas salivares labiales demostró las características clínicas ha-bituales de la sialoadenitis linfocítica crónica. Como las prue-bas, tanto clínicas como inmunológicas eran positivas, sospe-chamos una sialoadenitis linfocítica crónica simulando un sín-drome de Sjögren. El enzimoinmunoanálisis y el inmunoblot recombinante eran positivos para el virus de la hepatitis C (VHC). El ARN circulante del VHC fue detectado por PCR. Una biopsia hepática reveló una hepatitis crónica persistente. En una segunda biopsia de...

2. 3 Programa de Pós-Graduação em Geociências, Universidade Federal do Rio Grande do - A M. Fern; Farid Chemale; Maria Lídia M. V. Lelarge; João Luiz
Resumo – A margem passiva da costa da Namíbia registra uma longa história de atividade tectônica iniciada no Proterozóico. A colisão dos crátons do Congo e Rio de la Plata no Proterozóico Superior/Paleozóico Inferior gerou zonas de descontinuidade crustal no cinturão Kaoko que tornaram-se o local preferencial para as atividades tectônicas fanerozóicas. As reativações de estruturas pré-existentes em cinturões móveis estão intimamente relacionadas com a evolução das bacias de margem passiva adjacentes já que servem como corredores preferenciais para reativações e geração de falhas normais por abatimentos de blocos crustais. A Zona de Cisalhamento de Purros, de idade Pré-Cambriana, está...

3. 2001: Eastern North American transport climatology during high- and low-ozone days. Atmos - Bret A. Schichtel; Rudolf B. Husar
A synoptic scale transport climatology during days with high and low ozone concentrations was established for "ve summers from 1991 to 1995 over eastern North America. The airmass transport patterns were estimated from source impact regions derived from forward airmass histories. Daily maximum ozone concentrations were used to de"ne locally and regionally high- (90th percentile) and low- (10th percentile) ozone days. Examination of transport during locally high-ozone days revealed that there is poor transport in the central part of the domain, i.e. from Tennessee to northern Indiana, and in the South from Texas to South Carolina due to stagnating or...

5. IN THE NAVAJO NATION - Ethical Issues; Uranium Mining; D. Brugge; Bindu Panikkar; Doug Brugge
We explore the experience of Navajo communities living under the shadow of nuclear age fallout who were subjects of five decades of research. In this histori-cal analysis of public health (epidemiological) research conducted in the Navajo lands since the inception of uranium mining from the 1950s untill the end of the 20th century, we analyze the successes and failures in the research initiatives conducted on Navajo lands, the ethical breaches, and the harms and benefits that this research has brought about to the community. We discuss how scientific and moral uncertainty, lack of full stakeholder participation and community wide outreach...

6. Phonetics and Phonology then, and then, and now * - John J. Ohala
Phonetics attempts to describe and understand how speech is produced and perceived; phonology attempts to understand the patterning — in general, the behavior — of speech sounds in particular languages and in all languages. Is phonetics part of phonology? This straightforward question has received various answers at different points in the history of linguistics. In this paper I attempt to document that for the two centuries starting approximately with the eighteenth century, phonetics was well integrated into linguistics but that around the start of the 20th century phonetics and phonology were estranged, at least in some cases. During the second...

7. Peritraumatic ReactionsLawyer et l. Predictors of Peritraumatic Reactions and PTSD Following the September 11th Terrorist Attacks - Steven R. Lawyer; Heidi S. Resnick; Ro Galea; Jennifer Ahern; Dean G. Kilpatrick; David Vlahov
In this study the authors characterize peritraumatic reactions of residents of New York City during and immediately following the September 11th terrorist attacks, identify predictors of those reactions, and identify predictors of PTSD 4 months later. A cross–sectional sample of New York residents (n = 2,001) responded to questions about sociodemographics, historical factors, event–related exposure; acute cognitive, emotional, and physiological reactions to the September 11th ter-rorist attacks; and current (past month) PTSD symptoms. Factor analyses of peritraumatic reactions yielded three related, but distinct, peritraumatic response patterns—dissociation, emotional reactions, and panic/physiological arousal. Sev-eral demographic, historical, and exposure–related variables predicted one or...

8. Understanding Human DNA Sequence Variation at Pennsylvania State U niversity on M arch 1, 2014 http://jhered.oxfordjournals.org/ D ow nloaded from - K. K. Kidd; A. J. Pakstis; W. C. Speed; J. R. Kidd
Over the past century researchers have identified normal genetic variation and studied that variation in diverse human populations to determine the amounts and distributions of that variation. That information is being used to develop an understanding of the demographic histories of the different populations and the species as a whole, among other studies. With the advent of DNA-based markers in the last quarter century, these studies have accelerated. One of the challenges for the next century is to understand that variation. One component of that understanding will be population genetics. We present here examples of many of the ways these...

9. ACCOUNTING HISTORY RESEARCH: TRADITIONAL AND NEW ACCOUNTING HISTORY PERSPECTIVES * - Salvador Carmona; Mahmoud Ezzamel; Fernando Gutiérrez
Existe un debate en historia de la contabilidad acerca de las distintas formas cómo los materiales históricos deben ser recopilados, interpretados, analizados y, finalmente, sobre la forma cómo los mismos deben ser redactados. En cierta manera, el centro de este debate descansa en torno a la eternal polémica acerca de la “objetividad/subjetividad ” de la investigación histórica. Así, mientras que la corriente más ortodoxa sostiene la idea de una interpretación objetiva de la historia, el enfoque alternativo defiende una interpretación de carácter crítico. En este artículo, nosotros pretendemos hacer una valoración del debate entre los enfoques tradicional y de nueva...

In Review TRENDS in Ecology and Evolution Vol.22 No.7differing effects on the end of the growing season [10,11]. Global change experiments have also documented the influence of increasing temperature, shifting precipitation and other aspects of global change, such as rising CO2 concentrations on the timing of species and ecosystem-level phenology [12–15]. Finally, recent advances in species-specific phenological models now enable research-ers to scale from local to regional shifts in phenology [16], as well as to predict...

11. 182Original Article Pseudomonas aeruginosa Corneal Ulcer Related to Overnight Orthokeratology - Yeong-fong Chen Md Ken-kuo Lin
Background: Overnight orthokeratology was thought to be a safe and non-invasive alterna-tive for low-grade myopia and astigmatism correction. We assessed histories, clinical courses, and visual outcomes of the patients with pseudomonal ker-atitis related to overnight orthokeratology. Methods: The records of six patients with pseudomonal keratitis related to overnight orthokeratology were reviewed from January 2001 through December 2002. Results: The average age of the patients was 13 years. The average period between the time that the patient started the overnight orthokeratology program and the onset of infectious keratitis was 17 months. All patients presented with painful red eyes.

12. INFLATION COSTS, UNCERTAINTY COSTS AND EMERGING MARKETS - William Miles; Samuel Schreyer
Given the costs to real output that inflation uncertainty has been shown to impose, two recent papers have investigated the interaction of inflation and uncertainty for a group of emerging market nations. Both papers find that an increase in inflation almost invariably increases uncertainty in developing countries. This finding accords with the Friedman hypothesis, and with most results for industrialized countries. However, there is both theory and some tentative empirical evidence suggesting that, when inflation is high, and thus costly, an increase in inflation can spur greater investment in predicting the path of prices, and actually reduce, rather than increase...

Thermochronology relies on thermally-activated diffu-multi-domain, diffusion-profile, or track-length data are In many cases, however, obtaining a sufficiently nificantly increases the range of potential model thermal histories. Multi-domain diffusion (MDD) modeling ap-proaches have been developed that provide useful con-straints on potential nonmonotonic cooling paths such as maximum bounds on peak temperatures associated with

14. AMERICAN BEHAVIORAL SCIENTISTHirsch / EN EL NORTE L MUJ R MANDA En el Norte la Mujer Manda Gender, Generation, and Geography in a Mexican Transnational Community - Jennifer S. Hirsch
This study explores generational and migration-related changes in gender and marriage in two locations of a transnational community of Mexicans: the sending community in western Mexico and the receiving community in Atlanta. The principal method was life histories, focusing on 13 women in Atlanta and their sisters or sisters-in-law in Mexico; life history informants’mothers and husbands were also interviewed. A generational paradigm shift in marital ideals has occurred, from an ideal of respeto (respect) to one of confianza (trust), characterized by cooperative decision making, heterosociality, a less gendered division of labor in social reproduction, and a new role for marital...

15. Testicular sperm extraction in cancerous testicle in patients with azoospermia: A Case Report - Luca Carmignani; Franco Gadda; Giacomo Gazzano; Guido Ragni; Alessio Paffoni; Francesco Rocco; Giovanni Maria Colpi
The aim of this study is to evaluate the feasibility of testicular sperm extraction (TESE) in a cancerous testicle during orchiectomy for testicular neoplasm. This is a retrospective study and includes case histories of four azoospermic patients with incidental testicular cancer. None of the patients had fathered children prior to surgery and all patients were strongly motivated by the desire to have offspring. Patients underwent surgical exploration via inguinotomy and spermatic cord clamping. After nodule excision, micro-TESE was performed from the same albugineal incision, under microscopic guidance. Frozen section examination was not performed in the case of large nodules (>3...

19. ¿Cómo selecciona el profesorado recursos digitales para enseñar el Historia? - Flores H., Hazel C.; Rivero Gracia, María Pilar
The concept of historical time is complex but is fundamental to understanding History. This is recognized by all teachers participating in this research. Similarly, the use of digital resources is considered highly positive for the teaching of history. However this research shows that selecting digital resources by teachers is not done according to objective indicators of teaching quality of material to facilitate understanding of historical time, but that teachers lack analytical instruments to guide them in their resource selection and so they invest much time searching and selecting materials and, often, they decide going to known websites or blogs.

20. Tradutor e intérprete de língua de sinais: história, experiências e caminhos de formação - dos Passos, Gabriele C. R.; Anater, Gisele Iandra Pessini
http://dx.doi.org/10.5007/2175-7968.2010v2n26p207The aim of this article is to present Sign Language Translators and Interpreters (SLTIs) using current reflections and traditional longstanding concepts of the profession. Even locating interpreters of oral languages and of sign languages in the same chronological line, one should note the significant and clear differences between the two. Based on Rodrigues and Burgos (2001), and on the experiences of Brazilian SLTIs, we outline and highlight the characteristics that differentiate professionals working specifically with oral language from those in SLTI. It is important to mention that the result of the linguistic modality of signed language means that the competence...
