Fifty-one slimy sea plumes (Pseudopterogorgia americana Gmelin, 1791) were sampled for caridean shrimps at Guana Island, British Virgin Islands, during one week in July 1992. Sam- pling depth ranged from 3-22 m. Nine species were collected: Hippolyte nicholsoni Chace, 1972; Latreutes sp.; Neopontonides chacei Heard, 1986; Perclimenes cf. patae Heard and Spotte, 1991; Periclimenes cf. pauper Holthuis, 1951; Periclimenes sp.; Pseudocoutierea antillensis Chace, 1972; Tozeuma cf. cornutum Milne Edwards, 1881; and Trachycaris rugosa (Bate, 1888). A total of 1,418 specimens (including fragments) was obtained. The number of shrimp species per gorgonian ranged from 1-5; one gorgonian harbored 156 shrimps. The two predominant species, N. chacei and H. nicholsoni, occupy different mean depths (12.6 and 8.2 m, respectively). Sexual dimorphism assessed with Mann-Whitney U-tests was not apparent in the specimens of N. chacei (P > 0.05), but females of H. nicholsoni were significantly larger than males (P < 0.001). Minimum carapace length (CL, the tip of the rostrum to the posterior dorsal margin of the carapace) at which male N. chacei acquire a single appendix masculina spine is 1.25 mm; male H. nicholsoni can acquire a single spine at 0.9 mm CL. Histological sections of male N. chacei showed that shrimp with 0 or 1 spine are least likely to be mature. Female N. chacei can become ovigerous at 1.9 mm CL and female H. nicholsoni at 1.2 mm CL. The taxonomic status of 5 of the 9 species collected is uncertain.

Encontramo-nos inseridos em uma crise que afeta diversas dimensões da vida do planeta e imersos em uma sociedade pautada no 'progresso' civilizatório desenfreado que se utiliza da dominação como instrumento central. A percepção hegemônica atual se pauta no universo como um universo mecânico, no meio natural a puro serviço humano e na mulher inferiorizada, padronizada e subordinada ao homem. Este trabalho parte da necessidade de assinalar os mecanismos que dominam, excluem, padronizam e normatizam a maternidade como os mesmos que dominam a natureza e traçam a crise ecológica. Tendo como referencial teórico, o Ecofeminismo relaciona e interconecta os padrões de dominação da natureza como os mesmos que propagam a subordinação da mulher dentro de sistemas patriarcais. Utilizando como método a revisão bibliográfica não-sistematizada, a pesquisa traça paralelos entre movimentos feministas e ecológicos mostrando a maternidade como um foco a ser olhado cuidadosamente para termos uma quebra nos padrões atuais de desenvolvimento. Para melhor organização, registro do conteúdo e acesso às obras consultadas foram feitos fichamentos das mesmas com corpo contendo resumo, citações, transcrições e reflexões

This work analyzes the consequences of the intersection between the two spheres polis and oikos. It does so by examining themes present in three plays: Medea, Agamemnon and Lysistrata. The focus of the analysis is the way in which the feminine characters react to conflicts of interests in their respective situations. To fully comprehend which values correspond to which mentioned institution, the work also necessarily investigates the socialization and functions of both genders in fifth-century Athenian society. The analysis of the feminine condition in the creation myth implies the importance of the misogynistic sense of that time, which culminated in the silencing, discrediting, and systemic repression of females. The role of women in society, instilled in all girls starting in early childhood, is to succeed in marriage and domestic permanence. This lies opposite the masculine role, which was focused outside of the family center and to environments relating to war and public life. Matrimony and family, traditional female values, were threatened when overlapping with male interests, such as unavoidable war or social ascension through a different matrimonial bond. Therefore, it is possible to affirm that the opposition evident in the definitions male vs. female indicates that, in certain contexts, the interests of each element cause the conflicts present in the chosen plays

This study evaluates social inequalities in health according to level of schooling in the male population. This was a cross-sectional, population-based study with a sample of 449 men ranging from 20 to 59 years of age and living in Campinas, Sao Paulo State, Brazil. The chi-square test was used to verify associations, and a Poisson regression model was used to estimate crude and adjusted prevalence ratios. Men with less schooling showed higher rates of alcohol consumption and dependence, smoking, sedentary lifestyle during leisure time, and less healthy eating habits, in addition to higher prevalence of bad or very bad self-rated health, at least one chronic disease, hypertension, and other health problems. No differences were detected between the two schooling strata in terms of use of health services, except for dental services. The findings point to social inequality in health-related behaviors and in some health status indicators. However, possible equity was observed in the use of nearly all types of health services.

OBJECTIVE: To analyze cause-specifi c mortality rates according to the relative income hypothesis. METHODS: All 96 administrative areas of the city of Sao Paulo, southeastern Brazil, were divided into two groups based on the Gini coefficient of income inequality: high (>= 0.25) and low (<0.25). The propensity score matching method was applied to control for confounders associated with socioeconomic differences among areas. RESULTS: The difference between high and low income inequality areas was statistically significant for homicide (8.57 per 10,000; 95% CI: 2.60; 14.53); ischemic heart disease (5.47 per 10,000 [95% CI 0.76; 10.17]); HIV/AIDS (3.58 per 10,000 [95% CI 0.58; 6.57]); and respiratory diseases (3.56 per 10,000 [95% CI 0.18; 6.94]). The ten most common causes of death accounted for 72.30% of the mortality difference. Infant mortality also had signifi cantly higher age-adjusted rates in high inequality areas (2.80 per 10,000 [95% CI 0.86; 4.74]), as well as among males (27.37 per 10,000 [95% CI 6.19; 48.55]) and females (15.07 per 10,000 [95% CI 3.65; 26.48]). CONCLUSIONS: The study results support the relative income hypothesis. After propensity score matching cause-specifi c mortality rates was higher in more unequal areas. Studies on income inequality in smaller areas should take proper accounting of heterogeneity of social and demographic characteristics.

A phylogenetic analysis of a fragment of the mitochondrial gene 16S was used to test the monophyletic status of Potimirim. Existing doubts on the taxonomic status of brasiliana (once P glabra) and P potimirim (once P mexicana) were clarified. Potimirim mexicana and P potimirim are distinct species according to molecular data and appendix masculina morphology. A new species (Potimirim sp. 1) from Puerto Rico was revealed with molecular data, and it is evolutionarily related to P potimirim and P mexicana according to our analysis. We found out three distinct species under the name P glabra. Then, we recommend the application of the name P glabra for the populations of the Pacific slope of Central America and revalidation of P brasiliana for the Brazilian ones. The need for a new name to those "P glabra" of the Caribbean is highlighted, and it was provisionally referred as Potimirim sp. 2. The ontogenetic (juveniles to adults) development of the appendix masculina of P brasiliana was observed and compared to the other species of Potimirim (adults). In the light of our phylogenetic hypothesis, we postulate a pattern of character addition for the evolution of the appendix masculina of Potimirim. This hypothesis is plausible for two key reasons. First. Potimirim is a monophyletic group according to our hypothesis. Second, the shape of appendix masculina found in adults of P. americana is similar and comparable to those found in the earliest juvenile stages of P brasiliana, a derived species according to our phylogeny (P americana, ((P mexicana, Potimirim sp. 1. P potimirim), (P glabra, (brasiliana, Potimirim sp. 2)))). As so, the basal P americana retain the ancestral morphological state of the appendix masculina when compared to the other species of Potimirim. In our interpretation the ontogeny of the appendix masculina recapitulated the proposed phylogeny, giving further support to it.

No artigo discute-se a articulação entre sistemas de informações epidemiológicas, produção científica e políticas de saúde de assistência à saúde do homem. Foram utilizadas três fontes secundárias: dados do Ministério da Saúde (Sistemas de Informação sobre Mortalidade e Hospitalar, Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico), artigos publicados na SciELO e documentos do Ministério da Saúde referentes à saúde do homem. Os resultados apontam que, em termos de morbimortalidade, os homens estão mais expostos a riscos do que as mulheres. Na produção científica, predominam estudos que focalizam os agravos e doenças exclusivamente masculinos em detrimento de outros aspectos relacionados à saúde. Documentos legais destacam o panorama epidemiológico de morbimortalidade masculina e a metodologia de elaboração da política. É necessário que os pesquisadores ampliem a utilização dos dados dos sistemas de informações epidemiológicas do Ministério da Saúde e procedam à incorporação crítica da perspectiva relacional de gênero.

OBJETIVO: Comparar do débito cardíaco (DC) e a fração de ejeção (FE) do coração de fetos masculinos e femininos obtidos por meio da ultrassonografia tridimensional, utilizando o spatio-temporal image correlation (STIC). MÉTODOS: Realizou-se um estudo de corte transversal com 216 fetos normais, entre 20 a 34 semanas de gestação, sendo 108 masculinos e 108 femininos. Os volumes ventriculares no final da sístole e diástole foram obtidos por meio do STIC, sendo as avaliações volumétricas realizadas pelo virtual organ computer-aided analysis (VOCAL) com rotação de 30º. Para o cálculo do DC utilizou-se a fórmula: DC= volume sistólico/frequência cardíaca fetal, enquanto que para a FE utilizou-se a fórmula: FE= volume sistólico/volume diastólico final. O DC (combinado, feminino e masculino) e a FE (masculina e feminina) foram comparadas utilizando-se o teste t não pareado e ANCOVA. Foram criados gráficos de dispersão com os percentis 5, 50 e 95. RESULTADOS: A média do DC combinado, DC direito, DC esquerdo, FE direita e FE esquerda, para feminino e masculino, foram 240,07 mL/min; 122,67 mL/min; 123,40 mL/min; 72,84%; 67,22%; 270,56 mL/min; 139,22 mL/min; 131,34 mL/min; 70,73% e 64,76%, respectivamente; sem diferença estatística (P> 0,05). CONCLUSÕES: O DC e a FE fetal obtidos por meio da ultrassonografia tridimensional (STIC) não apresentaram diferença significativa em relação ao gênero.

Porokeratosis is a primary keratinizing disorder of unknown etiology. This disorder is characterized by the presence of centrifugally enlarging hyperkeratotic plaques, associated with the histopathological hallmark of cornoid lamellae. Genital porokeratosis is extremely rare. No more than thirty cases have been reported in the literature, including only one case of linear porokeratosis confined to the genital area. This case report describes a patient with genital linear porokeratosis, who was successfully treated with cryotherapy. Over two years of follow-up, the lesion improved and there was no evidence of recurrence or signs of malignant transformation. Nevertheless, there is a need for long-term follow-up data on recurrence and malignant transformation.

Trabalhos anteriores têm revelado vieses no reconhecimento de emoções e padrões diferenciais de ativação cerebral no transtorno de ansiedade social. No presente estudo, foi investigada a atribuição de emoções a faces neutras em 22 indivíduos com ansiedade social e 20 voluntários controles. Através do método da escolha forçada, participantes atribuíram emoções de alegria, medo, raiva ou tristeza a faces neutras. Verificou-se que homens e mulheres com ansiedade social atribuíram mais frequentemente emoções de raiva e tristeza às faces neutras, respectivamente. A atribuição de raiva por homens pode estar associada à tendência masculina em detectar sinais de hostilidade no ambiente social, enquanto que o aumento na atribuição de tristeza pelas mulheres pode estar associado à facilitação na identificação de emoções negativas. Os resultados sugerem que a ansiedade social afeta diferentemente os sexos e têm implicações importantes sobre o uso da face neutra como condição de base ou controle nas neurociências comportamentais.

A 36 year-old man after tests for assessing male infertility was diagnosed with primary infertility, bilateral cryptorchidism, non-obstructive azoospermia and discontinuous splenogonadal fusion. Carcinoma in situ was found in his left testicle, which was intra-abdominal and associated with splenogonadal fusion. To our knowledge, this is the fourth case of splenogonadal fusion associated with testicular cancer reported. One should always bear in mind the possibility of this association for the left cryptorchid testicle.
