High prevalence of intestinal infections and ectoparasites in dogs, Minas Gerais State (southeast Brazil)

AbstractFluorapatite with monazite-(Ce) and xenotime-(Y) microinclusions occurs in the lithium–caesium–tantalum pegmatite body A of the Volta Grande mine, Minas Gerais state, Southeast Brazil. The fluorapatite displays faint zoning, detected mainly by cathodoluminescence. Electron probe and laser ablation analyses indicate that zoning in the fluorapatite corresponds to variation in Mn and rare-earth element (REE) content. Such compositional variation is attributed to partial removal of the REE from the fluorapatite structure during a dissolution–reprecipitation process, forming monazite-(Ce) and xenotime-(Y) microinclusions in the REE-depleted zones of the fluorapatite. These inclusions exhibit an inherited geochemical signature, manifested by low Th and U concentrations when compared to monazite and xenotime crystallised from melts. Rhodochrosite and calcite inclusions are also associated with monazite-(Ce) and xenotime-(Y) and are probably products of the same process, recycling Ca, Mn, and CO32− from the fluorapatite through the following reaction: [Ca(5–2a–b–½x),Naa,(Y + REE)a,Mnb][(PO4)3–x(CO3)x(F)] + Fluid[a(2Ca2+ + P5+) + (x–b)(Ca2+) + H2O)] → [Ca5(PO4)3(F,OH)] + a[(Y + REE)PO4] + b[Mn(CO3)] + (x–b)[Ca(CO3)] + Fluid a[Na+].On the basis of new fluid-inclusion analyses, we propose that a hot (T > 204.5°C), salty (16 wt.% eq. NaCl, attributed to LiCl), hydrous fluid mediated the dissolution–reprecipitation of the fluorapatite. This fluid corresponds to similarly described Li-rich fluids which were suggested to have re-equilibrated the mineralogical assemblage at the Volta Grande mine.

Hibiscus L. is one of the largest genera of Malvaceae, Southeast Brazil has six endemic species of 14 native species, mainly distributed in cerrado. These Hibiscus are hairy shrubs, with showy flowers of pink corolla, dark base, 5-toothed staminal tube apex, loculicidal capsule of 5 cells. The species inhabit wet ecosystems of the atlantic rainforest and cerrado. After the last study of Hibiscus taxonomy evidencing four endemic species from Minas Gerais state, showed to have the largest endemism center of Hibiscus in Brazil, therefore, using IUCN classification methodology, we indicated H. hilarianus and H. multiformis as vulnerable, H. itirapinensis as endangered and H. mariae as critically endangered. The species are represented by small isolated populations distributed at the mountains and plateaus between Espinhaço mountain range and Planalto Paulista, considered a region with great endemic biodiversity. According to the previously analysis, it is recommended specific studies with techniques and appropriate methodology to research the development and evolutionary characteristics of hibiscus species in Minas Gerais state.

Objetivo: Identificar dentre acadêmicos de uma Faculdade de Medicina no Sul de Minas Gerais, usuários do metilfenidato, os principais motivos de utilização deste fármaco, as formas de aquisição e os possíveis efeitos colaterais. Materiais e Métodos: O estudo é descritivo e transversal e para a coleta de dados foi utilizado um questionário fechado, de caráter anônimo e de autopreenchimento, aplicado entre os meses de agosto e dezembro de 2015. Foram incluídos ao acaso 120 alunos dos 6 anos do curso médico. Resultados: Entre os participantes, 70 (58,33%) eram do sexo feminino e 50 (41,67%) eram do sexo masculino e a média de idade foi de 22,27 anos. Foi encontrada uma prevalência de 25% para o uso não prescrito de metilfenidato, com maior proporção de uso no sexo masculino. O aumento da concentração em época de provas foi citado como propósito de uso por 76,67% do total de pessoas que fazem uso indiscriminado. Além disso, 66,67% afirmaram ter tido o primeiro contato com a substância na faculdade e 60% obtiveram a droga por meio de doação de amigos. Os principais efeitos colaterais citados foram: ansiedade, insônia, euforia, taquicardia, redução de apetite, irritabilidade, cefaleia e tremores. Conclusão: O presente estudo evidencia uma elevada prevalência do uso não prescrito de metilfenidato, por acadêmicos de Medicina.Palavras-chave: Metilfenidato, Prevalência, Estudantes de MedicinaABSTRACTObjective: Identify among the academic students, users of methylphenidate in a medical school in the southern Minas Gerais, the main reasons for the use, the access and the possible side effects. Materials and Methods: The study is a cross-sectional, quantitative and descriptive study among 120 students of six series of the medical school.

Three New Species

AbstractThe present work presents a detailed taxonomic study on Ostracoda from the Quiricó Formation, Areado Group, São Francisco Basin, Brazil. The samples were collected from three outcrops in the Minas Gerais State: Tereza Farm (João Pinheiro Municipality), and from the banks of the São José and Quiricó creeks (Presidente Olegário Municipality). Sixteen ostracode species were recovered: Harbinia alta, Harbinia aff. H. angulata, Harbinia aff. H. crepata, Harbinia aff. H. salitrensis, Harbinia symmetrica, Brasacypris fulfaroi, Brasacypris ovum, Cypridea conjugata, Cypridea hystrix, Cypridea infima, Cypridea jequiensis, Neuquenocypris (Protoneuquenocypris) antiqua, Penthesilenula martinsi, Penthesilenula pintoi new species, Alicenula longiformis new species, and Timiriasevia sanfranciscanensis new species. With the recovery of well-preserved specimens, it was possible to observe new characteristics in Brasacypris ovum, Cypridea conjugata, C. hystrix, and C. infima, and propose emendments to them. Additionally, three new species are described: Penthesilenula pintoi n. sp., Alicenula longiformis, n. sp., and Timiriasevia sanfranciscanensis n. sp. To date, the genus Timiriasevia had not been recorded in strata from Brazil. Also, Darwinula martinsi is reassigned to the genus Penthesilenula. Several species herein recorded are also found in other Brazilian continental basins, as well as in African and Argentinian basins, contributing to the knowledge of Brazilian Cretaceous continental deposits.
