O aumento dos textos traduzidos e da investigação acadêmica no campo reichiano realça a necessidade de se estar atento à qualidade das traduções dos textos de Reich para o português. Utilizando a palavra Trieb como exemplo, o objetivo deste artigo foi identificar quais os termos utilizados nas traduções dessa palavra para o português. Os resultados demonstraram, a exemplo do que acontece nas traduções da obra freudiana, que os termos mais comuns são: pulsão, instinto e impulso. Tal variação de termos reforça a necessidade de se cotejar diferentes traduções de um mesmo texto, de se confrontar os textos traduzidos com os textos originais e de se ater ao devido uso de termos específicos, contribuindo para que se leia, da melhor forma possível, as ideias originais de Reich em português.

The testicular stroma of the vampire bat including the testicular capsula and the lamina propria of the seminiferous tubuli, was strongly PAS-positive. This observation was a possible indication of great amounts of structural glycogen and other glycoconjugates at the level of smooth muscle cells; elongated contractile cells and/or collagen frameworks of the tunica albuginea and tubular lamina propria. In the last the basement membranes of the seminiferous tubules were particularly strongly PAS positive, as an indication of their neutral mucosubstances structural composition, previously described (Malmi et al., 1987). The epithelium lining from the cavitary and surface rete testis complex showed low reactivities to mucosubstances; total proteins and lipids and oxidative enzymes studied. Although the apical granulation at the rete testis epithelium showed an intense PAS reactivity with hypothesis of glycoprotein secretion, through the rete. The PAS, Sudan Black B, NADH, MDH and LDH reactions of the testicular interstitium seem correlate to steroid metabolism (biosynthesis and secretion), at the Leydig cells level. The seminiferous epithelium generally had low reactions to all the histochemical studies realized. Particularly in the adbasal compartment the histochemical localizations of NADH diaphorase and LDH were possible related to glycolytic activities and general carbohydrates metabolism, both enzymes, and hydrogen transport, the NADH. The strong PAS, diastase and PAS, and alcian blue pH 2.5 and PAS reactions observed in the adluminal seminiferous epithelium compartment were directly related to the spermatids acrosomal glycoconjugates structuration. Also the SDH localization at this level seems to be related to the mitochondrial activities at the middle piece level in the late spermatids.

This paper deals with the ultrastructural study of mature vampire bat Sertoli cells and their relationships with the different stages of testicular germ cells. In vampire bat seminiferous epithelium there are different types of junctional specializations among Sertoli cells and among Sertoli cells and different germ cells, with special emphasis to tight junctions and to junctions like as desmosomes. Ectoplasmic junctions through the Sertoli cells, including the smooth ER, are observed. These cellular interactions and their cytophysiological roles are discussed. Also are related some ultrastructural peculiarities of the Sertoli cell nucleus, nucleolus, cytoplasmic organelles and lipidic inclusions.

Entre os anos de 1810 e 1850, a presença de trabalhadores escravos em Belém era significativa. Em termos demográficos, essa população representava quase metade da população da cidade, formada pelas freguesias urbanas da Sé e Campina. A presente dissertação analisa a escravidão em Belém, a partir de diversos aspectos como o tráfico, a procedência e/ou origem geográfica e étnica dos cativos, a demografia e as cores, mercado e a mobilidade cativa, o controle social e a liberdade escrava, permeados por acontecimentos sociais, políticos e econômicos ocorridos no Brasil e no Grão-Pará, no período em questão, tais como a chegada da família real e a abertura dos portos, a independência, a Cabanagem e a promulgação das leis anti-tráfico de 1815, 1831 e 1850. Narrativas de viajantes estrangeiros, jornais, inventários post-mortem, relatórios de governo, códigos de posturas e ações de liberdade são algumas das fontes utilizadas para construção do cenário: a Belém da primeira metade do século XIX, e para conhecimento da atuação de nossos atores: os trabalhadores escravos.

Hematological values from captive vampire bats Desmodus rotundus (E. Geoffroy, 1810). Desmodus rotundus is one of the hematophagous bat species that are responsible for significant losses to livestock and has important involvement on public health. The great interest on this bat species made it becomes the target of many investigations a required its maintenance in laboratories. Similarly to others mammals, hematological evaluation has been utilized to assess the health and morbidity state of bats, however there are scarce studies with captive bats. The aim of this study was to investigate the hypothesis that is possible to feed the vampire bat D. rotundus with frozen blood treated with citrate during a long captivity period without hematological dyscrasias. Therefore, complete blood count was performed monthly from 15 adult females kept for 345 days in cages and fed with frozen blood added to citrate. The erythrocyte concentration (9.02 ± 1.43 x1012/L), PCV (0.47 ± 0.08 L/L) and hemoglobin (163.9 ± 31.5 g/L) obtained from free-living bats (immediately after capture) were lower or similar to those obtained after 345 days of captivity, presenting erythrocytes’ count of 11.01 ± 0.82 x1012/L, packed cell volume of 0.50 ± 0.05 L/L and hemoglobin level of 158 ± 10.1 g/L. The total white blood cell (11.09 ± 6.07 x109 /L) and segmented neutrophil counts (9.85 ± 3.5 x109 /L) of free living D. rotundus decreased significantly after 345 days of captivity, with values of 3.98 ± 1.98 and 1.87 ± 978.6 x109 /L respectively, which are similar to bats from temperate regions in hibernation period. This study proved that is possible to feed D. rotundus for long periods of captivity with citrated blood without the occurrence of anemia, erythrocyte or other hematologic dyscrasia

This paper is part of a broader investigation on Epistemology of Biology carried out by a group of researchers from Cascavel/PR. It involves studies and research about biological thought on subjects such as the growing of the concepts of gene, genotype and phenotype. The aim of this research was to gather the undergraduate students of Biological Sciences’ views about the role played by the inclusion of a historical episode in the study group as a trigger for epistemological discussions and didactic reflections. Firstly, the students received Johannsen’s article “The genotype conception of heredity”, published in 1911 in the journal The American Naturalist, in which he proposed the concepts of genotype and phenotype, among other ones. After, there was a discussion held by group about the concepts proposed in the article taking into account the epistemological, historical and didactic aspects. Data collection occurred through the recording of the group discussions and individual interviews. The results suggest that the inclusion of this historical episode, enabled the participants to develop critical thinking through collective reflection on the meaning of biological knowledge in different contexts.

This thesis attempts to comprehend, through the work of Georg Simmel and Ulrich Beck, two distinct phases of modernity through the concept of individualism and individualization processes arising therefrom. A substantial formulation of the concept that remits to the conceptual transposition unscathed from one reality to another is not the main focus of this study. This is about, in advance, two distinct realities, conceptual and comparative examination that aims to weave the points pertaining to echoes - internalized and modified according to the complexity of the historical premises - the thought of Simmel in theoretical perspective of Beck. The forms can be characterized as individualism according to the socio-philosophical mores of Simmel in the intention to understand the forms assumed by individualism in modern history, as well as the derived individualization processes sustained by individual law. Therewith, is intended to transpose the optical analysis of contemporary Ulrich Beck and reap, through conceptual analysis, the points that refer to the influence and continuity of thought of Georg Simmel
