Abstract: the present work discusses the construction of 'otherness' understood as a permanent elaboration of the position of the subject facing the demands of contemporary subjetivation. the notion of difference is evoked in order to deal with the subjective movement, open and unstable, in the construction process of the other and of self. the contemporary city is brought here, through the discursive production of young people, in an intervention-research project, in which about 60 youth in the city of rio de janeiro, with ages between 11 and 13, from five different institutions, were invited to talk about their relationships with the other in the city. in this project, named city workshops, the youth debated about their difficulties in living together with the other and about the conflicts and the strangeness inherent in this relationship. through the analysis of group narratives, it was possible to establish the most significant figures of 'otherness' such as 'the loner', 'the poor' and 'the fox', which, regarded here as 'scales', determine new productions of meaning in the relationship i- the other in the city. we discussed how these figures of otherness are related to conflicts produced by contemporary demands, such as, individualization and the need to be included in the consumption society.

Abstract: the aim of this paper was to discuss the embryological aspects of müllerian duct anomalies and to analyze the current diagnostic methods and therapy. müllerian anomalies are congenital defects of the female reproductive tract resulting from failure in the development of the müllerian ducts and their associated structures. their cause has yet to be fully clarified, and it is currently believed to be multifactorial. symptoms appear principally during adolescence or early adulthood, and affect the reproductive capacity of these women. when clinically suspected, investigations leading to diagnosis include imaging methods such as hysterosalpingography, ultrasonography and magnetic resonance. the classification of these malformations relates to their embryogenesis, and defines the therapy and prognosis. müllerian anomalies consist of a wide range of defects that may vary from patient to patient. therefore, their management must also be individual, taking anatomical and clinical characteristics into consideration, as well as the patient's wishes.

Abstract: The aim of this study was to investigate the effect of a whole body vibration training program on knee extensor isokinetic peak torque, average power, and functional tests in the physically active elderly. Forty-seven subjects, who participated in a training program for the elderly, were recruited. The subjects were divided into two groups: whole body vibration group (WBV) (n=24, 70.7±5.8 years, 62.7±12.3 kg and 155.9±8.0 cm ) and control group (n=23. 70.0±5.7 years, 65.3±10.7 kg and 157.9±6.6 cm). The WBS group underwent whole body vibration exercise and their regular training program for 13 weeks, 2 times per week, whereas the control group performed the regular training program only. Whole body vibration training was not effective in increasing isokinetic peak torque, average power, or performance in the functional tests. On the other hand, the regular training program was effective in increasing elbow flexor strength endurance, distance covered in the 6-min walk test, and speed in the timed up and go test. The results suggest that vibration training is not effective in modifying functionality or muscle strength and power in the physically active elderly.

Abstract: data concerning the relationship between hepatitis b virus (hbv) genotypes and liver histology are scarce. the aim of this study was to compare hbv non-b and non-c genotypes according to demographic features, clinical status, hbv-dna levels and liver histology in rio de janeiro. one hundred twenty one consecutive chronic hbv-infected patients were enrolled during two-year period and data were prospectively collected. sera were tested for hbv genotyping using restriction fragment length polymorphism. liver biopsy was obtained from patients with either increased alanine aminotransferase (alt) or hbv-dna levels. genotype a was the most common, found in 82 (68%) patients, followed by f in 19 (15%), d in 17 (14%), b in one (1%) and c in two (2%). there was no association between hbv genotypes a, d and f and gender (p = 0.37), age (p = 0.78), race (p = 0.22), mode of infection (p = 0.94), hb "e" antigen status (p = 0.37) and hbv-dna levels (p = 0.47). the alt levels were lower in genotype d (75%) compared with a (47%) and f (55%) (p = 0.05). liver biopsy showed lower inflammation [histological activity index (hai) = 4] and fibrosis (f) (= 0) scores in genotype d than in genotypes a (hai = 5, p < 0.001; f = 2, p = 0.008) or f (hai = 5, p = 0.009; f = 2, p = 0.01). genotype a was the most prevalent in chronic hbv-infected patients and genotype d patients presented with less intense liver disease.

Autopsy and Case Reports , 2013,
Abstract: ST-segment elevation, observed in the critically ill patients, almost always raises the suspicion of ischemic heart disease. However, nonischemic myocardial and non-myocardial problems in these patients may also lead to ST-segment elevation. Pneumothorax and pneumopericardium have been rarely reported as a cause of transient ST-segment elevation. The authors report the case of a patient admitted to the emergency care unit because of a respiratory failure requiring mechanical ventilatory support. As the patient showed signs of clinical deterioration, a pneumothorax was clinically diagnosed. Chest radiography after thorax drainage also disclosed a pneumopericardium. The 12-lead electrocardiogram recorded before the thoracic drainage revealed an ST-segment elevation, which normalized after the surgical procedure. Ischemic myocardial biomarkers were negative. The authors call attention to the right-sided pneumothorax associated with pneumopericardium as an unusual cause of ST-segment elevation.

Abstract: single nucleotide polymorphisms (snps) in the interleukin (il)28b locus have been associated with a sustained virological response (svr) in interferon-ribavirin (ifn-rbv)-treated chronic hepatitis c virus (hcv)-infected patients in european and african populations. in this study, the genotype frequency of two il28b snps (rs129679860 and rs8099917) in a cohort of chronic hcv-monoinfected patients in brazil was evaluated and the snp sufficient to predict the treatment response outcome was determined. a total of 66 na?ve genotype-1 chronic hcv-infected patients were genotyped and the associated viral kinetics and svr were assessed. the overall svr was 38%. both the viral kinetics and svr were associated with rs129679860 genotypes (cc = 62% vs. ct = 33% vs. tt = 18%, p = 0.016). however, rs8099917 genotypes were only associated with svr (tt = 53% vs. tg = 33% vs. gg = 18%; p = 0.032). in this population, the analysis of a single snp, rs12979860, successfully predicts svr in the ifn-rbv treatment of hcv.

Abstract: the joint analysis of qualitative and quantitative variables has been considered a useful tool to estimate the genetic divergence among accessions of a gene bank. the purpose of this research was: (i) to characterize a collection of cherry tomatoes, using quantitative and qualitative descriptors, and (ii) to use gower's algorithm to quantify genetic divergence among genotypes, employing a joint descriptors analysis. forty accessions of organically grown cherry tomato were studied in seropedica, rio de janeiro, brazil. four qualitative fruit descriptors and nine qualitative descriptors were used. data were analyzed using gower's algorithm. there was variability for color, shape and number of locules per fruit. the red color was observed in fruits of 25 accessions. fruit with different colors such as yellow, orange and brown were also observed. regarding locule number, the presence of fruit with two, three, four and even with seven locules was detected. the upgma method resulted in the highest value for cophenetic correlation (0.80) and seven clusters were formed. the formed clusters made it possible to distinguish fruit classified as cherry tomato from other type grouped in different clusters, because the fruits this category were larger than cherry type considering the equatorial diameter of the fruit.
