RESUMO: A coturnicultura conta com um monitoramento sanitário e sistemas de manejo ainda em desenvolvimento quando comparado à avicultura industrial. Pesquisas de taxonomia e biologia parasitárias em codornas (Coturnix japonica) são pouco realizadas no Brasil, sendo a maioria das informações disponíveis referentes a relatos de caso em achados de necropsia, portanto, em muitos aspectos a fauna parasitária de codornas é ainda desconhecida. Este trabalho teve por objetivo realizar uma pesquisa parasitológica em codornas em fim de postura. Para pesquisa foram disponibilizadas 31 codornas com idades de 12 meses. As carcaças e suas vísceras foram encaminhadas ao Laboratório de Entomologia e Doenças Tropicais INPA, Manaus/AM. Foram estudados separadamente os sistemas circulatórios, nervoso, respiratório, digestivo e reprodutivo. Das 31 codornas examinadas nenhuma apresentou hemoparasitos, contudo, foram registradas nove espécies de endoparasitos distribuídas entre as classes Cestoda, Nematoda e protozoários. Os helmintos distribuíam-se pelo duodeno, jejuno, íleo, cecos e oviduto. O ceco foi o órgão mais parasitado e com maior diversidade de parasitas, sendo três espécies de protozoários e três de nematóides. Foram registrados seis morfotipos de Eutrichomastix globosus, sendo que, alguns morfótipos estavam hiperparasitados com esporângio Sphaerita sp. no citoplasma. Uma grande variedade de parasitos foi registrada nesta pesquisa, bem como, o protozoário Blastocystis hominis pela primeira vez sendo descrito para codornas.

ABSTRACT: The health monitoring and management systems of coturniculture can be deemed to be in a developmental phase when compared to the poultry industry. Studies regarding taxonomy and parasitic biology in quails (Coturnix japonica) has not been well conducted in Brazil. Most of the information is available from the autopsy case reports, in many ways the parasitic fauna of quails is still unknown. The aim of this study was to conduct a parasitological research in quails in order to contribute to ameliorate this situation. 31 quails, which were 12 months old, were used for the study. Their carcasses and viscera were sent to the Laboratory of Entomology and Tropical Diseases, INPA, Manaus/AM. The circulatory, nervous, respiratory, digestive and reproductive systems of these were studied separately. No blood parasites were found, however, nine species of endoparasites were registered which were distributed among the classes Cestoda, Nematoda and Protozoa. The helminths were distributed in the duodenum, jejunum, ileum, cecum and oviduct. The cecum was found to be the most parasitized organ and contained a wide range of parasites having three species of protozoa and three species of nematodes. Six morphotypes of Eutrichomastix globosus were recorded, and some morphotypes were hyperparasitized with sporangia Sphaerita sp. in the cytoplasm. A large number of parasites were recorded in this study, as well as the protozoan Blastocystis hominis was first being observed for quail.

RESUMO: Este trabalho avaliou se a higienização de alface americana com água ozonizada, na concentração de 1,0mg L-1 por 1, 2 ou 3 minutos, seria capaz de aumentar a vida útil do produto quando armazenado a 2ºC. Foram avaliadas as populações de microrganismos aeróbios mesófilos, Enterobacteriaceae, bolores e leveduras, coliformes totais, coliformes termotolerantes e pesquisa de Salmonella sp ao longo do tempo. Imediatamente após o processamento por 3 minutos, foram obtidas reduções decimais de 4,07; 3,36; 3,20; 2,18 e 2,18 de microrganismos aeróbios mesófilos, Enterobacteriaceae, bolores e leveduras, coliformes totais, coliformes termotolerantes, respectivamente. A presença de Salmonella sp. não foi observada em nenhuma das condições estudadas. Além do efeito na inativação inicial, o processamento com ozônio melhorou a estabilidade da alface durante a estocagem, aumentando o tempo para o início do crescimento microbiano (de zero para quatro dias) e reduzindo a taxa de crescimento dos microrganismos, especialmente quando a sanitização foi realizada por 3 minutos de contato. Os resultados demonstraram que a alface tratada com água ozonizada atendeu aos parâmetros da legislação durante o período avaliado, reduzindo a contaminação inicial das alfaces (que, sem tratamento, estavam microbiologicamente impróprias para consumo pela contagem de coliformes) e mantendo essas contaminações em níveis aceitáveis por até 10 dias, sob refrigeração.

ABSTRACT: This research studied the impact of Iceberg lettuce sanitation using ozonized water at 1.0mg L-1 for 1, 2 and 3 minutes in the vegetable shelf-life at 2ºC. It was evaluated populations of aerobic mesophilic bacteria, EnterobacterIaceae, molds/yeasts, total and thermtolerants coliforms, and Salmonella sp. Immediately after 3 minutes of sanitation, decimal reductions of 4.07 (aerobic mesophilic bacteria), 3.36 (EnterobacterIacea), 3.2 (molds/yeasts), 2.18 (total coliforms) and 2.18 (thermtolerants coliforms) were reached. Salmonella sp. was not founded at any evaluated condition. Additionally to the initial reduction, the ozonization improved the lettuce stability during its shelf-life, increasing the delay for microbial growth (from zero to four days) and reducing the microbial growth rate. It occurred especially when sanitation with ozone was carried for 3 minutes of contact. The results showed that the Iceberg lettuce sanitized with ozonated water meets the Brazilian law during the evaluated period, reducing lettuce initial load (that was initially unsafe due to high count of coliforms) and keeping this contamination acceptable for 10 days under refrigeration.

The stylohyoid process is a cylindrical bony structure surrounded by important anatomical structures including vessels and nerves. Calcification and elongation of the stylohyoid ligament complex over 30 mm may be associated with neck and facial pain, known as Eagle's syndrome. However, a bilateral ossified and elongated stylohyoid complex may be devoid of symptoms. We report a 79-year-old symptom-free female who presented on a routine conventional dental radiographic exam an 80.96 mm psendoarticulated stylohyoid complex in the left side and an 75.85 mm on the other. On CAT scan, both processes were calcified.

El proceso estilohioideo es una estructura ósea rodeada por nervios y vasos sanguíneos. La calcificación elongación del ligamento estilohioideo en más de 30 mm puede asociarse a dolor facial y del cuello, conocido como síndrome de Eagle. Sin embargo, esta alteración anatómica puede ser asintomática. Presentamos una mujer asintomática de 79 años a quien se le descubrieron procesos estilohioideo pseudo articulado de 80,96 mm a un lado y 75,85 mm al otro lado, en una radiografía dental convencional. En la tomografía axial computada, ambos procesos estaban calcificados.

Hepatitis C is a worldwide endemic disease, affecting roughly 200 million people. It has a variable prognosis, depending on the progression to fibrosis. During the last five years, the importance of apoptosis for the pathogenesis of various diseases, including hepatitis, has been recognized. It has been suggested that an increase in T cell-apoptosis during a hepatitis C virus infection is the cause of impaired regulation of the immune cellular response, helping to maintain infection. Thus, the interest in discovering the probable mechanisms by which the hepatitis C virus perpetuates in the liver, and to determine the conditions that predispose for progression of this disease, makes investigation of apoptosis in hepatic injury of great interest. We have made an overview of the various mechanisms by which the cell, more specifically the hepatic cell, is affected by apoptosis, and how it interacts with the hepatitis C virus and the immune system.
