Elliptical Orbit of Asteroid 1986 QE1
We present the orbital elements of asteroid QE1 (pro visional designation) identified in august 26, 1986, on a photographic plate obtained at the GPO telescope of the European Southern Observatory (ESO), La Silla, Chile, as well as the positions (AR and Dec) referred to 1950.0. Residues (0 - C) of the position in AR and Dec of the asteroid are given, both before and after applying variation in the geocentric distance.We present the orbital elements of asteroid QE1 (provisional designation) identified in august 26, 1986, on photographic plate obtained at the GPO telescope of the European Southern Observatory (ESO), La Silla, Chile, as well as the position in AR and Dec of the asteroid are given, both before and after applying variation in the geocentric distance
Determinação de posições de asteróides observados no Observatório Europeu Austral em setembro de 1987, La Silla, andes Chilenos, por meio de campo duplo em uma única placa fotográfica
In September 1987 we have observed minor planets at La Silla, ESO, with the GPO astrometric refractor (D = 40 cm; F=400 cm). Measures and reductions were performed at the Observatório do Valongo (UFRJ) with the Ascorecord measuring machine (0,1µ) and by means of five reference stars (SAO Star Catalogue - 1950,0). By the first time, double star field were used for saving time and photographic material.In September 1987 we have observed minor planets at La Silla, ESO, with the GPO astrometric refractor (D = 40 cm; F=400 cm).

Transitioning Adolescents Living With Hiv/aids To Adult-oriented Health Care: An Emerging Challenge
Objective: To review the literature on transition from pediatric to adult-oriented health care and discuss this issue in the specific context of chronic conditions. Sources: MEDLINE and LILACS were searched for relevant English and French-language articles published between 1990 and 2010. Summary of the findings: The transition of adolescents with chronic diseases from pediatric care to adult-oriented services has been a growing concern among pediatric specialties. In recent years, young people living with HIV/AIDS have begun to reach adulthood, giving rise to several challenges. The studies reviewed herein discuss such relevant topics as: the difference between transfer, an isolated event, and transition, a gradual process; the transition models used in different services; the importance of transitioning in a planned and individualized manner; the need for comprehensive interaction between pediatric and adult-oriented care teams; the importance of joint participation of adolescents, their families, and health professionals in the process; barriers to and factors that promote successful transitions; and the special needs of adolescents with HIV/AIDS in this important period of life. Conclusions: Several authors agree that transitioning adolescents to adult-oriented health care should be a gradual process not determined by age alone. It requires a plan established with ample dialogue among adolescents, their families, and pediatric and adult care teams. However, there is little evidence to support any specific model of health care transition. This should prompt researchers to conduct more prospective studies on the theme, especially in more vulnerable groups such as adolescents living with HIV/AIDS.

Immunoparasitological Diagnosis Of Strongyloides Stercoralis In Garbage Collectors In Uberlândia, Mg, Brazil
The objective of this study was to determine the presence of Strongyloides stercoralis in urban garbage collectors through the use of immunological and parasitological methods. A total of 92 individuals were evaluated from August, 1997, to June, 1998. For the parasitological diagnosis Baermann and Lutz' methods were applied. The immunological diagnosis involved the indirect fluorescence antibody test (IFAT) and the enzyme-linked immunosorbent assay (ELISA) to detect specific IgG antibodies. Of the 92 workers examined, six (6.5%) were infected with larvae of S. stercoralis. The IFAT detected 19 (16.3%) and the ELISA 17 (18.5%) positive serum samples. The differences between the results of parasitological and immunological methods were statistically significant (p<0.05). These results demonstrate that there is a need to improve the health conditions of this category of city employees.6203/04/15180182CONCHA, R., HARRINGTON, J.R.W., ROGERS, A.L., Intestinal strongyloidiasis: Recognition, management and determinants of outcome (2005) J Clin Gastroenterol, 39, pp. 203-211SIDDIQUI, A.A., BERK, S.L., Diagnosis of Strongyloides stercoralis infection (2001) Clin Infect Dis, 33, pp. 1040-1047FERREIRA, M., Strongyloidiasis and acquired immunodeficiency syndrome (2003) Enf Emerg, 5, pp. 18-26VADLAMUDI, R.S., CHI, D.S., KRISHANASWAMY, G., Intestinal strongyloidiasis and hyperinfection syndrome (2006) Clin Mol Allergy, 4, pp. 1-13BAERMANN G.

This paper refers to the observation of asteroids at the European Southern Observatory - ESO, La Silla. Chile, made by H. Debehogne (Observatoire Royal de Belgique), during february/march, 1986. The G.P.O. refractor (D= 40 cm; F= 4 m), was used. The plates were reduced at the Observatório do Valongo, UFRJ, using the Ascorecord coordinatograph and the Burroughs 6700 computer of the Núcleo de Computação Eletrônica, of the same University.Durante a missão do Observatório Real da Bélgica e do Observatório do Valongo (UFRJ) no Observatório Austral (ESO) em La Silla, Andes chilenos, em feveveiro/março de 1986, o astrônomo H.

Evidence for eosinophil recruitment, leukotriene B4 production and mast cell hyperplasia following Toxocara canis infection in rats
It is well known that eosinophilia is a key pathogenetic component of toxocariasis. The objective of the present study was to determine if there is an association between peritoneal and blood eosinophil influx, mast cell hyperplasia and leukotriene B4 (LTB4) production after Toxocara canis infection. Oral inoculation of 56-day-old Wistar rats (N = 5-7 per group) with 1000 embryonated eggs containing third-stage (L3) T. canis larvae led to a robust accumulation of total leukocytes in blood beginning on day 3 and peaking on day 18, mainly characterized by eosinophils and accompanied by higher serum LTB4 levels. At that time, we also noted increased eosinophil numbers in the peritoneal cavity. In addition, we observed increased peritoneal mast cell number in the peritoneal cavity, which correlated with the time course of eosinophilia during toxocariasis. We also demonstrated that mast cell hyperplasia in the intestines and lungs began soon after the T. canis larvae migrated to these compartments, reaching maximal levels on day 24, which correlated with the complete elimination of the parasite. Therefore, mast cells appear to be involved in peritoneal and blood eosinophil infiltration through an LTB4-dependent mechanism following T. canis infection in rats. Our data also demonstrate a tight association between larval migratory stages and intestinal and pulmonary mast cell hyperplasia in the toxocariasis model
Exclusive processes in electron - ion collisions
The exclusive processes in electron-ion () interactions are an important
tool to investigate the QCD dynamics at high energies as they are in general
driven by the gluon content of the target, which is strongly subject to parton
saturation effects. In this paper we compute the cross sections for the
exclusive vector meson production as well as the deeply virtual Compton
scattering (DVCS) relying on the color dipole approach and considering the
numerical solution of the Balitsky-Kovchegov equation including running
coupling corrections (rcBK). The production cross sections obtained with the
rcBK solution and bCGC parametrization are very similar, the former being
slightly larger.Comment: 6 pages, 4 figure
Constraining the nuclear gluon distribution in processes at RHIC
A systematic determination of the gluon distribution is of fundamental
interest in understanding the parton structure of nuclei and the QCD dynamics.
Currently, the behavior of this distribution at small (high energy) is
completely undefined. In this paper we analyze the possibility of constraining
the nuclear effects present in using the inclusive observables which
would be measured in the future electron-nucleus collider at RHIC. We
demonstrate that the study of nuclear longitudinal and charm structure
functions allows to estimate the magnitude of shadowing and antishadowing
effects in the nuclear gluon distribution.Comment: 6 pages, 3 eps figure
