Trypanosoma cruzi trypomastigotes induce cytoskeleton modifications during HeLa cell invasion
Fernandes, Maria Cecília;Andrade, Leonardo Rodrigues de;Andrews, Norma Windsor;Mortara, Renato Arruda;
Memórias do Instituto Oswaldo Cruz , 2011, DOI: 10.1590/S0074-02762011000800019
Abstract: it has been recently shown that trypanosoma cruzi trypomastigotes subvert a constitutive membrane repair mechanism to invade hela cells. using a membrane extraction protocol and high-resolution microscopy, the hela cytoskeleton and t. cruzi parasites were imaged during the invasion process after 15 min and 45 min. parasites were initially found under cells and were later observed in the cytoplasm. at later stages, parasite-driven protrusions with parallel filaments were observed, with trypomastigotes at their tips. we conclude that t. cruzi trypomastigotes induce deformations of the cortical actin cytoskeleton shortly after invasion, leading to the formation of pseudopod-like structures.

Abstract: the purpose of this work was to determine the influence of the interval between harvest and 1-mcp application on 1-mcp efficiency in delaying ripening in golden papaya. fruits were harvested from commercial orchards located in linhares, es, in a second stage of maturation, stored at 11±1oc and treated with 1-mcp (100 nl.l-1) 0, 1, 2 and 3 days after harvest. treated and non-treated fruits were kept at 11±1oc for 6 days and, then, were stored at 22±1.5oc and 80-90%rh until complete ripening. 1-mcp delayed loss of firmness and skin color changes. non-treated fruits reached ideal firmness for consumption between the 2nd and 4th day of storage at 22oc. fruits treated with 1-mcp on the 2nd or 3rd day after harvest reached consumption stage between the 8th and 10th day of storage at 22oc. while fruits treated with 1-mcp one day after harvest reached optimum firmness for consumption on the 12th day of storage at 22oc, those treated on the harvest day did not softened. though more subtly, skin color behaved in a similar way as firmness. there was a slight increase in soluble solids amounts in fruits along ripening. the lower the interval between harvest and 1-mcp application, the longer the 1-mcp efficiency in delaying ripening in golden papaya. this is the key information when defining the application procedure for 1-mcp as a ripening regulator.

Abstract: As doen as pós-colheita podem ser responsáveis por perdas tiabendazol (10 mg.L-1) e imazalil (1 mg.L-1). Frutos tratados com significativas ao citricultor. Este trabalho objetivou: a) caracterizar imazalil apresentaram a menor incidência (5,4%) de doen as pós-as doen as pós-colheita em laranjas 'Pêra' provenientes de cultivo colheita, enquanto que frutos provenientes de pomares organicos organico e convencional, com ou sem tratamento pós-colheita com apresentaram a maior incidência (25,2%). As principais doen as pósimazalil, comercializadas na CEAGESP; e b) detectar a presen a de colheita foram o bolor verde em frutos produzidos em sistema isolados de Penicillium digitatum resistentes a fungicidas em frutos convencional e as podrid es pedunculares de lasiodiplodia e de com bolor verde. Frutos permaneceram em camara úmida por 24 phomopsis em frutos organicos. A frequência relativa de isolados de horas, e por mais 13 dias a 25 oC e 85% de UR. A incidência de P. digitatum resistentes ao fungicida tiabendazol foi menor em frutos doen as foi avaliada visualmente a cada 2-3 dias. A presen a de P. organicos, enquanto a frequência de isolados de P. digitatum resistentes digitatum resistente a fungicidas foi avaliada em fun o do crescimento ao imazalil e à mistura tiabendazol+imazalil foi maior em frutos que micelial em meio batata-dextrose-ágar acrescido dos fungicidas receberam tratamento pós-colheita com imazalil. Postharvest diseases may be responsible for significant losses to added of the fungicides thiabendazole (10 mg.L-1) and imazalil (1 citrus growers. This study aimed to: a) characterize the postharvest mg.L-1). Fruits treated with imazalil had lower incidence (5.4%) of diseases in 'Pêra' oranges from organic and conventional crops, with postharvest diseases, while fruits from organic crop had the highest or without postharvest treatment with imazalil, marketed in incidence (25.2%). The main postharvest diseases were green mold CEAGESP; and b) detect the presence of Penicillium digitatum isolates in fruits produced in the conventional system and Lasiodiplodia and resistant to fungicides in fruits with green mold. Fruits were kept in a Phomopsis stem-end rot in organic fruits. The relative frequency of humid chamber for 24 hours and for additional 13 days at 25 oC and P. digitatum isolates resistant to the fungicide thiabendazole was 85% RH. The disease incidence was visually evaluated at every 2-3 lower in organic fruits, while the frequency of P. digitatum isolates days. The presence of P. digitatum resistant to the fungicides was resistant to imaza

Abstract: A dor orofacial comumente ocorre devido à inflama o aguda ou cr nica. Porém, pouco se sabe sobre os mecanismos fisiopatológicos envolvidos na inflama o e na dor inflamatória presentes nas disfun es temporomandibulares. Nosso objetivo foi desenvolver um modelo para o estudo da inflama o aguda na regi o da articula o temporomandibular (ATM) de ratos utilizando carragenina (CA) e verificar os possíveis efeitos de drogas antiinflamatórias nesse modelo. A inflama o foi avaliada através do extravasamento plasmático (EP) do corante azul de Evans, por espectrofotometria comparada à ATM contralateral que serviu como controle e recebeu inje o de salina. Um experimento com rela o ao tempo do efeito da CA sobre o EP do corante Azul de Evans revelou um efeito máximo no tempo de 60 min após a administra o. O experimento dose resposta demonstrou que a administra o de CA a partir da dose de 300ug/50uL, causava um EP estatisticamente significante em rela o ao controle. A administra o de drogas antiinflamatórias (dexametasona e meloxicam) somente foram capazes de reduzir a inflama o em altas doses. Concluímos que pico de EP induzido pela administra o periarticular de CA ocorre em 60 minutos e que o EP induzido pela CA pode ser inibido pelos antiinflamatórios dexametasona e meloxicam.
