Entre a frieza, o cálculo e a "vida loka": violência e sofrimento no trajeto de um adolescente em cumprimento de medida socioeducativa

O conceito de sofrimento social caracteriza-se pela compreensão das situações de aflição e dor como experiências sociais e não como problemas individuais. Este trabalho analisa a natureza social e política do sofrimento de um adolescente em cumprimento de medida socioeducativa. Inspirado na abordagem de Veena Das, o artigo se apóia em "carne" e discurso para problematizar a relação entre cidadania e segmentos juvenis discriminados, que se manifesta nas ambiguidades das práticas institucionais presentes no fluxo de execução de medidas socioeducativas. O artigo analisa as contradições entre o objetivo institucional de evitar a reincidência de atos infracionais, auxiliando o adolescente a tornar-se um cidadão autônomo, e as narrativas e expressões corporais dos adolescentes durante o cumprimento das medidas. A trajetória aqui descrita leva ao reconhecimento de que o trânsito da medida de internação para as medidas em meio aberto se dá sob a tensão entre o discurso institucional de reorganizar a vida escolar, familiar e comunitária e a experiência cotidiana dos adolescentes, que segue marcada pela constante ameaça policial e pela privação de acessos a bens públicos. O cumprimento de medidas socioeducativas acaba por reforçar entre os adolescentes a aflição de serem socialmente tidos como suspeitos e fugitivos e, consequentemente, a incorporação de um lugar social particular, o de membro do "mundo do crime". O desempenho na vida cotidiana de um "estilo bandido" revela formas de resposta ao discurso dominante no sistema socioeducativo, contexto que indica o paradoxo do Estado brasileiro, que garante uma democracia formal enquanto viola direitos civis.

PENCALC: a program for penetrance estimation in autosomal dominant diseases

We present a computer program developed for estimating penetrance rates in autosomal dominant diseases by means of family kinship and phenotype information contained within the pedigrees. The program also determines the exact 95% credibility interval for the penetrance estimate. Both executable (PenCalc for Windows) and web versions (PenCalcWeb) of the software are available. The web version enables further calculations, such as heterozygosity probabilities and assessment of offspring risks for all individuals in the pedigrees. Both programs can be accessed and down-loaded freely at the home-page address http://www.ib.usp.br/~otto/software.htm.

Var transcription profiling of Plasmodium falciparum 3D7: assignment of cytoadherent phenotypes to dominant transcripts

Background: Cytoadherence of Plasmodium falciparum-infected red blood cells is mediated by var gene-encoded P. falciparum erythrocyte membrane protein-1 and host receptor preference depends in most cases on which of the 50-60 var genes per genome is expressed. Enrichment of phenotypically homogenous parasites by panning on receptor expressing cells is fundamental for the identification of the corresponding var transcript. Methods: P. falciparum 3D7 parasites were panned on several transfected CHO-cell lines and their var transcripts analysed by i) reverse transcription/PCR/cloning/sequencing using a universal DBL alpha specific oligonucleotide pair and ii) by reverse transcription followed by quantitative PCR using 57 different oligonucleotide pairs. Results: Each cytoadherence selected parasite line also adhered to untransfected CHO-745 cells and upregulation of the var gene PFD995/PFD1000c was consistently associated with cytoadherence to all but one CHO cell line. In addition, parasites panned on different CHO cell lines revealed candidate var genes which reproducibly associated to the respective cytoadherent phenotype. The transcription profile obtained by RT-PCR/cloning/sequencing differed significantly from that of RT-quantitative PCR. Conclusion: Transfected CHO cell lines are of limited use for the creation of monophenotypic cytoadherent parasite lines. Nevertheless, 3D7 parasites can be reproducibly selected for the transcription of different determined var genes without genetic manipulation. Most importantly, var transcription analysis by RT-PCR/cloning/sequencing may lead to erroneous interpretation of var transcription profiles.

Beauty, Class and Discourse: Issues in Debate

In this text we proceed through a brief review of Naomi Lee`s (2009) article, highlighting her significant contributions to social and cultural psychology. In our dialogue with her text we inquire about some arguments and methodological procedures she presents. We raise some specific questions related to how the issue of beauty is framed, and we ponder on how a broadening of the scope to include history-of ideas, of relations-would bring some important elements to her approach. As Lee relates beauty and class, we examine the nuanced meanings of lack and deficiency in her analytical work. We also discuss her assumptions and position concerning discourse and dialogue which mark her ways of proceeding through the analysis of the interviews. We speculate that the depersonalized answer appointed in the interviewees` discourse can be related to a way of considering beauty as disembodied.

Language, discourse and politics

After discussing the meaning of the word politics, this paper shows that there are four possible approaches to the issue of the relationships between language, discourse and politics: a) the intrinsic political nature of language; b) the relations of power between discourses and their political dimension; c) the relations of power between languages and the political dimension of their usage and; d) linguistic policies. This paper addresses only the first two of these items. Languages have an intrinsically political nature because they subject their speakers to their order. The acts of silencing operationalized in discourse manifest a relation of power. The spread of discourses in the social space is also subject to the order of power. The use of language may be the space of pertinence, but is also that of exclusion, separation and even the elimination of the other. Therefore, language is not a neutral communication tool, but it is permeated by politics, by power. Because of the dislocations that it produces, literature is a form of swindling language, unveiling the powers that are imprinted on it.

Hodgkin`s Lymphoma Presenting as Dominant Gastric Lesion in Immunocompetent Patients: Report of 5 Cases With EBV Analysis

Primary Hodgkin`s lymphoma (HL) of the stomach is an extremely rare entity. Most cases of gastric involvement by HL are observed in the setting of disseminated disease. The nonspecific nature of the symptoms and endoscopic findings, which include a large malignant-looking ulcer and mass or wall thickening, together with the considerable histological overlap between HLs and some non-HLs or undifferentiated carcinoma, make the surgical resection diagnosis extremely difficult. An accurate diagnosis is important as treatment and outcome differ significantly for these neoplasms. In small endoscopic gastric biopsies and even in postoperative specimens, the precise histological diagnosis of HL is particularly challenging. Here, the authors report 5 cases of 2 women and 3 men aged 22 to 68, with gastric involvement by classic HLs-3 primary gastric HLs and 2 as part of widespread disease. All 5 patients presented with digestive symptoms. At endoscopy, the lesions presented as ulcerated and elevated lesions, with or without mucosal thickening. Four patients were misdiagnosed in the preoperative biopsy or in the gastrectomy specimen. Association with Epstein-Barr virus (EBV) was detected in 4 cases, with a predominance of subtype A EBV. These cases illustrate the significant difficulties, both clinical and pathological, in achieving the diagnosis of HL involving the stomach in immunocompetent patients.

Linkage to chromosome 2q36.1 in autosomal dominant Dandy-Walker malformation with occipital cephalocele and evidence for genetic heterogeneity

We previously reported a Vietnamese-American family with isolated autosomal dominant occipital cephalocele. Upon further neuroimaging studies, we have recharacterized this condition as autosomal dominant Dandy-Walker with occipital cephalocele (ADDWOC). A similar ADDWOC family from Brazil was also recently described. To determine the genetic etiology of ADDWOC, we performed genome-wide linkage analysis on members of the Vietnamese-American and Brazilian pedigrees. Linkage analysis of the Vietnamese-American family identified the ADDWOC causative locus on chromosome 2q36.1 with a multipoint parametric LOD score of 3.3, while haplotype analysis refined the locus to 1.1 Mb. Sequencing of the five known genes in this locus did not identify any protein-altering mutations. However, a terminal deletion of chromosome 2 in a patient with an isolated case of Dandy-Walker malformation also encompassed the 2q36.1 chromosomal region. The Brazilian pedigree did not show linkage to this 2q36.1 region. Taken together, these results demonstrate a locus for ADDWOC on 2q36.1 and also suggest locus heterogeneity for ADDWOC.

Neurophysiological findings of the late-onset, dominant, proximal spinal muscular atrophies with dysautonomia because of the VAPB PR056SER mutation

The vesicle-associated membrane protein/synaptobrevin-associated membrane protein B (VAPB) Pro56Ser Mutation has been identified in Brazilian families showing various motor neuron syndromes. However, the neurophysiological characteristics of these patients have not been detailed, and some questions Still need to be solved, such as the possible presence of myotonia and the origin of the abdominal protrusion seen in most patients. The eventual finding of suggestive electrophysiological characteristics would be helpful not only for clinical diagnosis but also to selection of the appropriate DNA test. To clarify these questions we carried out sensory and motor conduction Studies, including symphatetic skin response, and needle examination in six genetically proven affected members. The electromyographic findings were those of a slowly progressive motor neuron disorder. Topographically, the abdominal muscles were severely affected, but the facial and laryngeal muscles were preserved or very mildly involved. Sensory conduction studies and sympathetic Skin responses were normal. No myotonic discharge was recorded. These findings are indistinguishable from those of other motor neuron disorders, although the predominant involvement of the proximal limbs and of the abdominal muscles may be of some help in the appropriate clinical setting.

Association of Dominant and Recessive Genes Confers Anthracnose Resistance in Stem and Leaves of Common Bean

Different genes might be involved in Colletotrichum lindemuthianum resistance in leaves and stem of common bean. This work aimed to study the genetic mechanisms of the resistance in the leaf and stem in segregating populations from backcrosses involving resistant cultivar AN 910408 and susceptible cultivar Ruda inoculated with spore suspensions of C. lindemuthianum race 83. Our results indicate that two genes which interact epistatically, one dominant and one recessive, are involved in the genetic control of leaf anthracnose resistance. As for stem anthracnose resistance, two genes also epistatic, one dominant and one recessive, explain the resistance to C. lindemuthianum race 83. The recessive gene is the same for leaf and stem resistance; however, the dominant genes are distinct and independent from each other. The three independent resistance genes of AN 910408 observed in this work could be derived from Guanajuato 31.

Sickness and Aggressive Behavior in Dominant and Subordinate Mice

Sick animals show a set of organized behavioral changes (sickness behavior), which is the result of a motivational re-organization of the behavior as a whole. Sickness behavior display can be influenced by the social context. In this work, we sought to investigate the regulation of sickness behavior within a pair of mice in the presence of an intruder mouse. Dominant and subordinate mice were treated with the bacterial endotoxin lipopolysaccharide (LPS) and were challenged with the presence of an intruder mouse. LPS effects depended on ranking and social context. Even though dominant mice displayed more agonistic interaction towards the intruder, subordinate mice displayed agonistic behavior towards the intruder when their dominant companion was treated with LPS. The results show that, not only sickness behavior is differentially expressed among different social ranks, but also that sickness behavior is related to different reactions among surrounding animals. These data are relevant for a biological approach to the relation between sickness behavior and social behavior.

Oculoauriculovertebral spectrum: report of nine familial cases with evidence of autosomal dominant inheritance and review of the literature

Oculoauriculovertebral spectrum (OAVS; OMIM 164210) is a complex condition characterized by defects of aural, oral, mandibular and vertebral development. The aetiology of this condition is likely to be heterogeneous; most cases are sporadic, however, familial cases suggesting autosomal recessive end autosomal dominant inheritance have been reported. In this study, we describe the clinical aspects of nine familial cases with evidence of autosomal dominant inheritance and compare them with reports in the literature. Interfamilial and intrafamilial clinical variabilities were observed in this study (reinforcing the necessity of careful examination of familial members). We suggest that oculoauriculovertebral spectrum with autosomal dominant inheritance is characterized mainly by bilateral auricular involvement and rarely presents extracranial anomalies.

Mandibulofacial Syndrome With Growth and Mental Retardation, Microcephaly, Ear Anomalies With Skin Tags, and Cleft Palate in a Mother and Her Son: Autosomal Dominant or X-Linked Syndrome?

We report on a Brazilian mother and her son affected with mandibulofacial dysostosis, growth and mental retardation, microcephaly, first branchial arch anomalies, and cleft palate. To date only three males and one female, all sporadic cases, with a similar condition have been reported. This article describes the first familial case with this rare condition indicating autosomal dominant or X-linked inheritance. (C) 2009 Wiley-Liss, Inc.

Non-random reef use by fishes at two dominant zones in a tropical, algal-dominated coastal reef

Habitat use and the processes which determine fish distribution were evaluated at the reef flat and reef crest zones of a tropical, algal-dominated reef. Our comparisons indicated significant differences in the majority of the evaluated environmental characteristics between zones. Also, significant differences in the abundances of twelve, from thirteen analyzed species, were observed within and between-sites. According to null models, non-random patterns of species co-occurrences were significant, suggesting that fish guilds in both zones were non-randomly structured. Unexpectedly, structural complexity negatively affected overall species richness, but had a major positive influence on highly site-attached species such as a damselfish. Depth and substrate composition, particularly macroalgae cover, were positive determinants for the fish assemblage structure in the studied reef, prevailing over factors such as structural complexity and live coral cover. Our results are conflicting with other studies carried out in coral-dominated reefs of the Caribbean and Pacific, therefore supporting the idea that the factors which may potentially influence reef fish composition are highly site-dependent and variable.

WNT5A Mutations in Patients With Autosomal Dominant Robinow Syndrome

Robinow syndrome is a skeletal dysplasia with both autosomal dominant and autosomal recessive inheritance patterns. It is characterized by short stature, limb shortening, genital hypoplasia, and craniofacial abnormalities. The etiology of dominant Robinow syndrome is unknown; however, the phenotypically more severe autosomal recessive form of Robinow syndrome has been associated with mutations in the orphan tyrosine kinase receptor, ROR2, which has recently been identified as a putative WNT5A receptor. Here, we show that two different missense mutations in WNT5A, which result in amino acid substitutions of highly conserved cysteines, are associated with autosomal dominant Robinow syndrome. One mutation has been found in all living affected members of the original family described by Meinhard Robinow and another in a second unrelated patient. These missense mutations result in decreased WNT5A activity in functional assays of zebrafish and Xenopus development. This work suggests that a WNT5A/ROR2 signal transduction pathway is important in human craniofacial and skeletal development and that proper formation and growth of these structures is sensitive to variations in WNT5A function.

Large time behaviour for functional differential equations with dominant eigenvalues of arbitrary order

The spectral theory for linear autonomous neutral functional differential equations (FDE) yields explicit formulas for the large time behaviour of solutions. Our results are based on resolvent computations and Dunford calculus, applied to establish explicit formulas for the large time behaviour of solutions of FDE. We investigate in detail a class of two-dimensional systems of FDE. (C) 2009 Elsevier Inc. All rights reserved.
