Anesthesia by sprinkling method in the gills of tambaqui Colossoma macropomum does not influence intensity and morphology of monogeneans.

Abstract: The present study evaluates the influence of anesthesia on the parasitic fauna of monogenea fish parasites, as its intensity and viability. Two experiments were conducted: Evaluation of an anesthetic method by sprinkling eugenol directly on gills and evaluation of monogenea motility and viability; Comparison of immersion and directly sprinkling on the gills with benzocaine and eugenol followed by evaluation on parasite intensity. The results suggest that the anesthetic sprinkling didn't interfere in the parasite motility, morphology and body surface integrity analyzed by fluorescence method. The monogenean intensity in the gills was lower in fish anesthetized by immersion method compared to the sprinkling method and the control group. This method of anesthesia can be used in parasitological studies.

Principais distúrbios traumato-ortopédicos atendidos em clínicas-escola de fisioterapia

Abstract: Introducao: As alteracoes musculoesqueleticas sao um importante problema de saude e necessitam ser tratadas, dentre os diversos locais publicos e privados que disponibilizam tratamento adequado, destacam-se as clinicas-escola de fisioterapia. Objetivo: Descrever atraves dos atuais estudos a prevalencia dos principais disturbios traumato-ortopedicos em pacientes atendidos em clinicas-escola de fisioterapia do pais. Metodologia: Trata-se de uma revisao de literatura onde foram realizadas buscas nas plataformas de pesquisa SciELO, Periodicos CAPES e Google academico. Para realizacao das buscas, foram utilizados os seguintes descritores: perfil epidemiologico, perfil de atendimentos, clinica-escola, traumatologia e Ortopedia, depois de aplicados os criterios de exclusao, a pesquisa limitou-se a 07 artigos. Resultados: Todas as pesquisas analisadas sao do tipo transversal, tiveram como forma de coleta de dados a analise de prontuarios, o periodo de investigacao das pesquisas variou de 1 a 7 anos, as areas do pais mais estudadas foram a regiao sul e nordeste, os disturbios traumato-ortopedicos mais prevalentes foram: artrose, fraturas e lombalgia sendo a dor a principal queixa relatada. Consideracoes finais: As clinicas-escola de fisioterapia do pais realizam um relevante trabalho na reabilitacao de diversos disturbios traumato-ortopedicos, configurando-se como espacos de ensino-aprendizagem e pesquisa.

Pre-Columbian lead pollution from Native American galena processing and land use in the midcontinental United States

Abstract: The presence and sources of pre-Columbian (before 1492 CE) lead (Pb) pollution in the midcontinental United States were investigated using geochemical and Pb isotope analyses on sediment cores recovered from Avery Lake, a floodplain lake located directly adjacent to the Kincaid Mounds archaeological site on the lower Ohio River, Illinois. Geochemical results indicate the presence of Pb pollution during the Baumer (300 BCE to 300 CE) and Mississippian (1150–1450 CE) occupations, and since the 1800s. Pb isotope results link Mississippian Pb pollution to the processing and use of galena primarily from southeastern and/or central Missouri, and to a lesser extent the upper Mississippi River valley, with ∼1.5 t (metric tons) of galena-derived Pb deposited in Avery Lake during this time. Pb pollution during the Baumer phase, equating to ∼0.4 t of Pb, was not accompanied by a Pb isotope excursion and most likely originated from local biomass burning. These results provide new information about the environmental impacts associated with pre-Columbian Native Americans’ interaction with and utilization of their landscape and its resources.
