Abstract: this work reports the first record of omnivory behavior of diabrotica speciosa (coleoptera, chrysomelidae), leptoglossus zonatus (hemiptera, coreidae), monocrepidius aff. posticus and monocrepidius fuscofasciatus (coleoptera, elateridae) on fall armyworm spodoptera frugiperda (lepidoptera, noctuidae) egg masses in maize fields. macrophotography was used to record the activity of these insects on fall armyworm sentinel egg masses during 2009 and 2010 maize growing seasons. the presence of omnivorous insects changes the species population dynamics within the ecosystem. therefore, the implications of these interactions should be understood and taken into consideration for integrated pest management enhancement.

Abstract: staphylococcus lugdunensis is a rare cause of severe infections and clinical manifestations are similar to those related to s. aureus infection. we describe a hospital-acquired bacteremia due to methicillin-resistant staphylococcus lugdunensis, misidentified as methicillin-resistant s. aureus. the oxacillin mic was 16 μg/ml and the meca gene and sccmec type v were determined by pcr. although treatment had been appropriated, the patient died after rapid progressive respiratory failure and another nosocomial sepsis. it is important not only to identify s. lugdunensis in view of its clinical course, but also to determine its susceptibility to oxacillin by detecting the meca gene or its product.

Abstract: This study has the objective of evaluating the efficiency of a dose of 1 mL (250 ?g of cloprostenol) in the vulvar submucous, in the group 2 (G2) of 25 cows, in relation to an intramuscular dose of 2 mL (500 ?g of cloprostenol) formed by the group 1 (G1) of 24 cows Nelore-Chianina, totaling 49 female repeatbreeders. The cows were with at least 120 days period post partum remaining in the reproductive season between December 2003 and February 2004. The application of cloprostenol was repeated eleven days after in the cows did not show estrus until 5 days of the first dose. The total percentage of estrus were of 79.16% (G1) and 56% (G2). The media of the hours for estrus being present was of 81.35 hours (first dose) and 92.8 hours (second dose) and 71.5 hours (first dose) and 76.1 hours (second dose) for G1 and G2 respectively. In relation to the media hours for the presence of estrus, in the groups G1 and G2 for first dose, second dose, and for the total number of cows in estrus, there were no significant difference (p>0.05). The artificial inseminations were performed 12 hours after the appearance of estrus and the gestation diagnostic at 53 days after the last insemination by means of rectal palpation confirmed by transrectal ultrasonography where 20 cows were diagnosed as gestating. Ten in the G1 and ten in the G2 totaling 40.8% gestating. The strategic application of cloprostenol is suggested for the cows repeatbreeders at the end of the reproductive season. Este estudo teve como objetivo avaliar a eficiência do cloprostenol na indu o do estro e taxa de gesta o em vacas de corte “repeat-breeders”, comparando a eficiência de meia dose na submucosa vulvar. Foi utilizada dose de 1 mL (250 ?g de cloprostenol) na submucosa vulvar no grupo 2 (G2) = 25 vacas; e dose clássica de 2 mL (500 ?g de cloprostenol) intramuscular, formado pelo grupo 1 (G1) = 24 vacas meio sangue Nelore-Chianina, totalizando 49 fêmeas “repeat-breeders”, com escore corporal 3,5 (1 a 5), sem altera es ao exame ginecológico. As vacas se encontravam com 175±13 dias de período pósparto, mantidas em esta o de cobertura durante 89 dias, entre Dezembro de 2003 e Fevereiro de 2004. Foram inseminadas uma vez, seguidas por duas a três coberturas naturais, efetuadas por touros aptos após exame andrológico, acasalados na propor o de 1:20. A aplica o de cloprostenol foi repetida 11 dias após a primeira dose, nas vacas que n o apresentaram estro. Realizou-se rufia o 2 vezes ao dia, durante cinco dias após a aplica o de qualquer dose de cloprostenol. As percentagens totais de estro foram de
Second Language Acquisition: Reconciling Theories  [PDF]

This article argues that previous attempts to explain SLA should not be disregarded. Instead, when they are put together, they provide a broader and deeper view of the acquisition process. There is evidence to support the claim that second language acquisition (SLA) is a complex adaptive system due to its inherent ability to adapt to different conditions present in both internal and external environments. Based on this understanding, widely discussed second language theories, including behaviorism, will be treated as explanations of parts of a whole, since each captures a different aspect of SLA. In order to justify this assumption, excerpts from some English language learning histories are provided to exemplify how learners describe their learning processes. The final claim is that SLA should be seen as a chaotic/complex system.

Abstract: Pre-treatment of non-infected human monocytes with L. intermedia SGS followed by LPS-stimulation led to a significant decrease in IL-10 production accompanied by a significant increase in CD86, CD80, and HLA-DR expression. Pre-treatment with SGS followed by LPS stimulation and L. braziliensis infection led to a significant increase in TNF-α, IL-6, and IL-8 production without significant alterations in co-stimulatory molecule expression. However, pre-treatment with L. intermedia SGS did not result in significant changes in the infection rate of human monocytes.Our data indicate that L. intermedia saliva is able to modulate monocyte response, and, although this modulation is dissociated from enhanced infection with L. braziliensis, it may be associated with successful parasitism.Leishmaniasis is a protozoan parasitic infection transmitted by sand flies. Different species of Leishmania are associated with distinct clinical forms of disease. Cutaneous leishmaniasis (CL) caused by Leishmania major is usually benign; infection of human hosts leads to the development of a localized cutaneous lesion that eventually heals, leading to the generation of life long-immunity. In contrast, CL caused by L. braziliensis is distinguished from other leishmaniasis by its chronicity, latency, and tendency to metastasize in the human host [1]. In this disease, a single ulcer with elevated borders and a necrotic centre is frequently observed, and a chronic inflammatory response develops despite the paucity of parasites. In 1–5% of patients, muco-cutaneous leishmaniasis may occur due to the intrinsic ability of L. braziliensis to persist within lesion scars after spontaneous or chemotherapy-mediated healing and its ability to metastasize to the nasal mucosa [2-4].Leishmania parasites are transmitted to the vertebrate host when the sand fly probes for a blood meal. During blood feeding, sand fly saliva, which contains a great variety of hemostatic, inflammatory, and immunomodulatory molecul
Ressonancia magnética e características clínicas em adultos com doen?as desmielinizantes monofásicas: encefalomielite aguda disseminada ou uma variante da esclerose múltipla?
Arquivos de Neuro-Psiquiatria , 1999, DOI: 10.1590/S0004-282X1999000500019
Abstract: acute disseminated encephalomyelitis (adem) is a widespread monophasic inflamatory disease affecting the central nervous system, that usually follows an infection or vaccination. in this study, we present an analysis of magnetic resonance imaging (mri), cerebrospinal fluid (csf) and clinical aspects in four patients with clinical diagnosis of adem. the presence of mri demyelinating lesions was crucial, but not in itself sufficient for definitive diagnosis. clinical and mri follow up, in order to exclude new lesions and to reevaluate the former ones, as well as csf, were important for the differential diagnosis with other demyelinating diseases, particularly multiple sclerosis. in addition, we have shown that early treatment with methylprednisolone after the initial symptoms was effective for improving clinical manifestations as well as for reducing mri lesions.

Abstract: introduction: the genus staphylococcus is of great importance because of its high prevalence in hospital infections and because it presents high rates of resistance to oxacillin and other antimicrobials. thus, evaluation of the accuracy of the phenotypic methods that are used to determine the profile of antimicrobial resistance is essential to ensure that the most appropriate therapy is chosen. methods: one hundred and fourteen strains of staphylococcus sp (53 s. aureus and 61 cns) were used to evaluate the accuracy of the methods of disk diffusion, agar microdilution, oxacillin screening agar and automated systems, in comparison with pcr for investigating resistance to oxacillin. results: the meca gene was detected in 48 strains (42.1%), and 27 strains (23.7%) showed discrepant results in at least one of the methods (74.1% of cns, 25.9% of s. aureus). for s. aureus, with the exception of the microscan walkaway, all the methods showed 100% specificity and sensitivity. in relation to cns, the automated system and cefoxitin disk had lower accuracy. conclusions: use of two methods should be the best option for improved accuracy, especially when the diagnostic laboratory only uses an automated system or oxacillin disk diffusion test. combination of these methods with others presented almost 100% sensitivity and specificity in our study.
