Villarreal, LYB;Assayag, MS;Brand?o, PE;Chacón, JLV;Bunger, AND;Astolfi-Ferreira, CS;Gomes, CR;Jones, RC;Ferreira, AJP;
Revista Brasileira de Ciência Avícola , 2006, DOI: 10.1590/S1516-635X2006000200010
Abstract: this article reports a survey on turkey astrovirus (tastv) and turkey coronavirus (tcov) infections with rt-pcr in 17 turkey flocks affected by acute enteritis and two apparently normal turkey flocks located in the southeastern region of brazil by pcr (tastv and tcov). seven out of the 17 affected flocks were positive for tastv and 14 for tcov, with seven co-infections. in one of the two apparently normal flocks, a tastv-tcov co-infection was found. although a definitive association of these agents and the signs can not be made, the implications of these findings are discussed.
Diagnosis of infectious bronchitis: an overview of concepts and tools
Villarreal, LYB;
Revista Brasileira de Ciência Avícola , 2010, DOI: 10.1590/S1516-635X2010000200006
Abstract: infectious bronchitis (ib) casues multi-systemic infection in chickens with signs similar caused by other poultry pathogens and thus a high diagnostic accuracy can only be achieved by s series of laboratory assays. this article reviews in a brief way the traditional virus assays such as embryo innoculation, tracheal rings and virus neutralization assays for the direct detection of avian infectious bronchitis virus (ibv) and methods based on gene molecular biology and some assays for the detection of anti-ibv antibodies, including elisa. a critical view on each technique is also provived by the author.
East and West: Orientalism, war and the colonial present
Assayag,Jackie;
Etnográfica , 2007,
Abstract: for at least two hundred years, western countries have exercized a "benevolent" violence through colonization. advocated in the name of the "civilizing mission" of the west and inspired by eschatology, this calling held the promise of redemption, both for the colonizer and for the colonized. the "war declared on terrorism" after the massacre of 9/11 in new york, with the subsequent military operations in afghanistan and in iraq, revives this tradition of ameliorative interventionism by carrying on the old orientalist-related topoi. far from effacing the great divide between the west and the rest, the wars of a putatively new type reinforce and polarize the division between "civilized" and "barbaric" in the era of "globalization". the unfolding ideology of the american, according to which there would no longer be "outside" or "inside", because no country would now be exempt from terrorism, obscures at little cost, but not ineffectually, the "colonial present". what now prevails is a sombre vision of globalization, that of a fight to the death between two worlds, extending over all continents, between the "empire of the good", incarnated by america, and the "empire of evil", incarnated by islamic terrorism. but this novelty goes back to schemas that are as old as the united states itself, insofar as this self-proclaimed "exceptional", "unilateral" and "providential" "imperial republic" has an idealistic or utopian component qualified as "indispensable". welcome the the "wilsonism in boots"!
East and West: Orientalism, war and the colonial present Este e Oeste: Orientalismo, guerra e a contemporaneidade colonial

Abstract: For at least two hundred years, Western countries have exercized a "benevolent" violence through colonization. Advocated in the name of the "civilizing mission" of the West and inspired by eschatology, this calling held the promise of redemption, both for the colonizer and for the colonized. The "war declared on terrorism" after the massacre of 9/11 in New York, with the subsequent military operations in Afghanistan and in Iraq, revives this tradition of ameliorative interventionism by carrying on the old orientalist-related topoi. Far from effacing the Great Divide between the West and the Rest, the wars of a putatively new type reinforce and polarize the division between "civilized" and "barbaric" in the era of "globalization". The unfolding ideology of the American, according to which there would no longer be "outside" or "inside", because no country would now be exempt from terrorism, obscures at little cost, but not ineffectually, the "colonial present". What now prevails is a sombre vision of globalization, that of a fight to the death between two worlds, extending over all continents, between the "Empire of the Good", incarnated by America, and the "Empire of Evil", incarnated by Islamic terrorism. But this novelty goes back to schemas that are as old as the United States itself, insofar as this self-proclaimed "exceptional", "unilateral" and "providential" "imperial republic" has an idealistic or utopian component qualified as "indispensable". Welcome the the "Wilsonism in boots"! Ao longo de pelo menos duzentos anos, os países ocidentais exercitaram uma violência "benevolente" através do colonialismo. Advogado, à época, em nome de uma "miss o civilizadora" do Ocidente e inspirado na escatologia, este chamamento invocava a promessa da reden o, tanto para o colonizador como para o colonizado. A declara o de "guerra ao terrorismo" depois do massacre de 11 de Setembro em Nova Iorque, e as subsequentes opera es militares no Afeganist o e no Iraque, revive esta tradi o de "intervencionismo melhorador" ao transportar os velhos topoi orientalistas. Longe de erradicar a Grande Divis o entre o West e o Rest, as novas guerras refor am e polarizam a divis o entre "civilizados" e "bárbaros" numa era de "globaliza o". A crescente ideologia dos norte-americanos, segundo a qual n o haveria mais lugar para o "fora" e o "dentro" porque nenhum país está a salvo do terrorismo, ofusca superficialmente (mas também com eficácia) a "contemporaneidade colonial". Prevalece hoje uma vis o sombria da globaliza o, a vis o de uma guerra mortífera entre dois mundos, es
Mosaicism for combined tetrasomy of chromosomes 8 and 18 in a dysmorphic child: A result of failed tetraploidy correction?
Gunnar Houge, Helle Lyb?k, Sasha Gulati
BMC Medical Genetics , 2009, DOI: 10.1186/1471-2350-10-42
Abstract: In a markedly dysmorphic child with heart malformations and developmental delay, CGH analysis of newborn blood DNA suggested a 50% dose increase of chromosomes 8 and 18, despite a normal standard karyotype investigation. Subsequent FISH analysis revealed leukocytes with four chromosomes 8 and four chromosomes 18. The child's phenotype had resemblance to both mosaic trisomy 8 and mosaic trisomy 18. The double tetrasomy was caused by mitotic malsegregation of all four chromatids of both chromosome pairs. A possible origin of such an error is incomplete correction of a tetraploid state resulting from failed cytokinesis or mitotic slippage during early embryonic development.This unique case suggests that embryonic cells may have a mechanism for tetraploidy correction that involves mitotic pairing of homologous chromosomes.Unlike meiotic non-disjunctions, mitotic non-disjunctions are rarely observed in humans with the exception of mosaicism for trisomy 8, 9 or 20 [1,2]. In some cases mosaic trisomy of more than one chromosome have been seen [3]. Such mosaic variegated aneuploidy is due to mitotic errors, often associated with premature centromere division [4]. In contrast to mosaic trisomies, the finding of mosaic whole-chromosome tetrasomy is without precedence. Here we present such a patient; a dysmorphic newborn child with mosaicism of leukocytes containing 50 chromosomes due to tetrasomy of chromosomes 8 and 18. This unique clinical case may have relevance concerning the origin of aneuploidy in cancer [5-8] because it indirectly suggests that there might be a mechanism for tetraploidy correction during fetal development that involves mitotic pairing of homologous chromosomes.A baby girl was delivered by cesarean section in week 36 due to maternal hypertension with mild preeclampsia, birth weight 2910 g, length 47 cm. Polyhydramnios was detected at the end of the pregnancy. She had persistent ductus arteriosus (PDA), a small muscular-type ventricle septal defect (VSD)

Journal of Cardiothoracic Surgery , 2010, DOI: 10.1186/1749-8090-5-45
Abstract: From January 2008 to December 2008, 46 consecutive patients received pleural decortications for empyema thoracis. Post-procedural and malignancy-related empyemas were excluded. After hydro-pneumatic test and surgical correction of AL (until satisfaction), patients were assigned (23 per group) to Control or Sealant group. Control group underwent no additional interventions. In Sealant group, lung sealant was applied over AL areas. Following variables were measured daily: patients with AL; time to chest drainage (CD) removal; CD drainage volume at removal, postoperative length of hospital stay, postoperative C-reactive protein (CRP), and leukocyte counts. Personnel recording parameters were blinded to intervention. Two-tailed t-tests (normally distributed data) or Mann - Whitney U-test (not-normally distributed data) were used for evaluating significance of differences between group means or medians. Significance of any proportional differences in attributes were evaluated using Fisher's Exact Test. Statistical analysis was carried out using R-software (version 2.8.1).Groups were similar regarding demographic and baseline characteristics. No patients were withdrawn from study; no adverse effects were recorded. There were no significative differences on CRP and leukocyte levels between two groups. Compared with the Control group, in Sealant group significantly fewer patients had AL (30 versus 78%, p = 0.012), and drains were inserted for a shorter time (medians, 3 versus 5 days, p = 0.05). Postoperative hospitalization time was shorter in Sealant group than in control group, but difference was not significant (0.7 days, p = 0.121).Pleuraseal? Lung Sealant System significantly reduces AL following pleural decortications for empyema and, despite of not-increased infectious indexes, is suitable for routinely use, even in procedures with contaminated pleura.Prolonged parenchymal air leak is the most common complication after lung resection [1]. Prolonged air leak lead to p
Serum AChE Activities Predict Exercise Heart Rate Parameters of Asymptomatic Individuals  [PDF]

Neuroscience & Medicine (NM) , 2010, DOI: 10.4236/nm.2010.12007
Abstract: Background specific heart rate parameters notably associate with variable risks of cardiovascular disease and mortal-ity, however, to date there are no readily available blood tests associated with these parameters. Because of the estab-lished parasympathetic contributions towards cardiac regulation, we challenged the working hypothesis that serum acetylcholinesterase (AChE) activity is involved. Methods A total of 403 Healthy men and women were included in the study and underwent treadmill exercise testing. Prior to exercise testing the subject’s serum AChE activity levels were assessed by measuring rates of acetylthiocholine hydrolysis. Results In male subjects AChE activity was positively cor-related to resting heart rate (r = 0.210, p = 0.001). Complementing this observation, AChE activity was negatively correlated to the exercise-induced heart rate increase (r = –0.181, p = 0.005) and to heart rate recovery at 1, 2 and 5 minutes following cessation of exercise (r = –0.150, p = 0.022; r = –0.157, p = 0.016; r = –0.176, p = 0.008 respec-tively). This indicated that lower than average AChE activities, which presumably reflect increased peripheral ACh levels, might be correlated to favorable heart rate parameters. Similar observations were made in female subjects, ex-cept for lack of correlation to their resting heart rate. Additionally, we observed that we were able to stratify subjects into two groups of significantly different AChE activity (p = 0.001) based on a cut point of heart rate recovery below 20 beats one minute after cessation of exercise. Conclusion In asymptomatic individuals lower than average AChE activity is associated with favorable indices of exercise-inducible heart rate increase as well as heart rate recovery. Future studies will be needed to evaluate the added prognostic significance gained by implementing this marker into routine practice.

Gelisp: A Library to Represent Musical CSPs and Search Strategies
Mauricio Toro,Camilo Rueda,Carlos Agón,Gérard Assayag
Computer Science , 2015,
Abstract: In this paper we present Gelisp, a new library to represent musical Constraint Satisfaction Problems and search strategies intuitively. Gelisp has two interfaces, a command-line one for Common Lisp and a graphical one for OpenMusic. Using Gelisp, we solved a problem of automatic music generation proposed by composer Michael Jarrell and we found solutions for the All-interval series.
