Diversity of Social Wasps on Semideciduous Seasonal Forest Fragments with Different Surrounding Matrix in Brazil

We surveyed social wasps (Polistinae) present in forest fragments of northwest of São Paulo state with different surroundings composed of a matrix of citrus crops and sugarcane in the expectation that the former matrix would be more diverse than the latter. We collected specimens actively using attractive liquids. We obtained 20 species in Magda, 13 in Bebedouro, 13 in Matão, and 19 in Barretos. The most common genus was Agelaia in all of the areas. The greatest Shannon-Wiener index of diversity was obtained in Magda (H′=2.12). Species such as Brachygastra moebiana, Metapolybia docilis, Mischocyttarus ignotus, M. paulistanus and M. consimilis had not been recorded on recent surveys in the state. Furthermore M. consimilis is a new record for the state. We concluded that, with our data, a relation between the occurrence of social wasps and the surrounding matrix was not detected

EXCLUSÃO E RAÇA: INCURSÕES A PARTIR DO “RACISMO DE ESTADO” DE MICHEL FOUCAULT SOBRE O PROBLEMA DAS EXPERIÊNCIAS DAS DESIGUALDADES

O presente trabalho discute como a exclusão social pode se dar por meio da exploração e reprodução no campo das raças. Procura-se entender as condições dentro das quais essa categoria bélico-política opera. No primeiro momento, são analisadas as noções de “racismo de estado” e “biopoder”. Em seguida, são apresentadas algumas considerações que tocam às construções de formas sociais, dando ênfase no Direito como categoria ativadora de todo o “racismo de estado”. Ao final, apresenta-se a situação atual em que vivemos, a partir da necessária mudança das configurações em defesa de um ambiente menos inóspito para toda a espécie humana

Morphology and Histochemistry of the Venom Apparatus in Different Castes of the Ant Ectatomma vizottoi (Formicidae: Ectatomminae)

The elimination of toxins via a venom gland by some ant species is a component of a larger mechanism for capturing prey and defense. The present study describes the morphology and histochemistry of the venom apparatus of different castes of the ant Ectatomma vizottoi Almeida, 1987. Morphologically, the venom apparatus of queens, gynes and workers of E. vizottoi are similar and composed of the sting apparatus and three distinct portions: two secretory portions (convoluted gland and secretory filament), and a storage portion (reservoir) - a hollow sting apparatus covered in the terminal portion of the reservoir by a sclerotized cuticle. The venom gland of E. vizottoi is longer in queens and gynes than in workers. Furthermore, the epithelium of the convoluted gland is taller in the glands of queens and gynes than in workers, which may be indicative of greater toxin synthesis, or may be related to different body sizes of the castes. The morphology and histology of the venom apparatus reflect those of a generalist, while the histochemical tests indicated that this structure has the same chemical content of lipids, proteins and polysaccharides among queens, gynes, and workers. Images obtained by confocal microscopy and scanning electronic microscopy reveal a muscle layer surrounding the reservoir that is interlaced with secretory filaments, which fixes, in a manner, the filaments in place. This musculature serves to eject stored venom, which likely leads to greater success in defense or foraging

Analysis of bone mineral loss by dental panoramic radiography in men over 40 years old in the state of Roraima / Análise da perda mineral óssea por radiografia panorâmica dentária em homens com mais de 40 anos de idade no estado de Roraima

Background: The present study was conducted to understand the possible application of panoramic radiography as an alternative diagnostic measure for the detection of osteopenia and osteoporosis. Moreover, we surveyed to understand the oral hygiene of the participants.Materials and Methods: A questionnaire-based survey for self-assessment was done, followed by a detailed radiographic evaluation and Cortical Mandibular Index (ICM) and Mentonian Index (IM) recording. Later, statistical analyses were done for descriptive analysis and possible important factors responsible for the obtained ICM and IM values. Results: The obtained results suggested that for the present study population of 112 participants, and considered 25 parameters, age was a major factor (P 0.00456) along with the use of a personal toothbrush (P 0.01265), and exchange of a new toothbrush (P 0.0293). These factors were significantly influential on the ICM outcomes (P 0.06645) whereas the influence of the considered parameters was not significantly influential on IM results. Conclusion: The descriptive results suggested that osteopenia and osteoporosis were dominant among the patients as confirmed by the radiographic analysis. Hence, panoramic radiography can be an effective alternative in the diagnosis of osteoporosis. However, confirmation should be obtained from further large-scale studies on diverse populations with more contributing factors

O DISPOSITIVO PEDAGÓGICO DAS REVISTAS CONTIGO! E ROLLING STONE EM RELAÇÃO A PABLLO VITTAR

Este artigo analisa as edições n. 2.192 e 137 das revistas Contigo! e Rolling Stone, publicadas respectivamente em setembro de 2017 e janeiro de 2018. Tais revistas apresentam práticas linguísticas em relação à cantora Pabllo Vittar que parecem desestabilizar o binômio masculino-feminino, constituinte do que se convencionou denominar língua portuguesa.  A construção do corpus de análise pauta-se na pesquisa documental, sendo formado por quinze excertos retirados de ambas as revistas analisadas. Os resultados sugerem que as revistas funcionam como um dispositivo pedagógico que, por meio das práticas linguísticas relacionadas a Pabllo Vittar, nos ensinam modos outros de ser e estar no mundo social. Palavras-Chave: concepção de língua; binômio masculino-feminino; dispositivo pedagógicoTHE PEDAGOGICAL DEVICE OF THE MAGAZINES WITH YOU!

Those magazines introduce linguistic practices related to the singer Pabllo Vittar that seem to desestablish the masculine-feminine binomial, which constitutes what is considered as the Portuguese language. Results suggest that the magazines function as a pedagogical device that, among the linguistic practices related to Pabllo Vittar, teach us other ways of being and living in the social world. Keywords: concept of language; masculine-feminine binomial; pedagogical device 

SOIL CHEMICAL ATTRIBUTES AND THEIR INFLUENCE ON ELEMENTAL COMPOSITION OF YERBA MATE LEAVES

Yerba mate (Ilex paraguariensis St. Hil.) is a raw material used in making a beverage whose chemical composition can be altered by the growing environment and the management adopted during its cultivation. Thus, it is essential that scientific studies are undertaken to understand the chemical composition of yerba mate related to its growing environment. The aim of this work was to determine the elemental composition in the leaves of yerba mate from native cultivations that had never received fertilization and liming, from the Southern Region of the state of Paraná, Brazil. Soil and leaf samples were collected at 11 sites located in the municipalities of São Mateus do Sul, Mallet, São João do Triunfo, and Lapa. Leaf analyzes were performed in an Optical Emission Spectrometer with Inductively Coupled Plasma. The mean concentrations observed (mg kg-1), in decreasing order, were: Ca – 7880; K – 7310; Mn – 2418; - Mg – 820; P – 720; Al – 474; Fe – 231; B – 78; Zn – 62; Ba - 62; Cu – 8.9; Ni – 5.6; Cr – 0.82; V – 0.53; Co – 0.17. The Mn concentrations were directly correlated with Al3+ saturation and inversely correlated with base saturation, pH, and the available Ca2+, demonstrating that changes among these soil components can significantly modify the Mn concentrations in the yerba mate leaves. The high concentrations of Mn and Al in the leaves of yerba mate demonstrate the adaptation of this species to acidic soils with high saturation of Al3+.Yerba mate (Ilex paraguariensis St. Hil.) is a raw material used in making a beverage whose chemical composition can be altered by the growing environment and the management adopted during its cultivation.

Eficácia anti-helmíntica da ivermectina em equinos: exames coproparasitológicos e hematológicos

O objetivo do presente estudo foi avaliar a eficácia da ivermectina a 2% em equinos, através de exames coproparasitológicos e hematológicos. O experimento foi realizado em uma fazenda no município de Uberlândia, MG. Foram utilizados 24 equinos, de três a oito anos, divididos em dois grupos, conforme valores dos OPG. Contagens de OPG e coproculturas foram realizadas nos dias D0, D+7 e D+14. Os animais foram tratados com a formulação pasta a base de ivermectina 2%, na dose de 200 mcg/kg, via oral. Amostras de sangue foram coletadas nos dias D0, D+7 e D+14 para avaliação dos parâmetros hematológicos. A presença de ovos, característicos da família Strongylidae e identificação de larvas características de ciatostomíneos demonstrou o parasitismo dos animais por pequenos estrôngilos. Nos D+7 e D+14 houve a redução significativa do OPG no grupo tratado com eficácia de 99,5 e 99,7%, respectivamente. Observou-se tendência do quadro eritrocitário manter-se próximo aos limites inferiores e discreta leucocitose com neutrófilos próximos dos valores superiores. Pode-se inferir que a ivermectina é eficaz contra os ciatostomíneos e alterações hematológicas significativas não foram observadas.Palavras-chave: Ciatostomíneos; Equinos; Nematódeos; OP
