Juliana Garlet,Maína Roman,Ervandil Corrêa Costa
Biotemas , 2010,
Abstract: The objective of this study was to determine qualitatively and quantitatively the pentatomid fauna associated with the canopy of different native species during the period from September 2005 to September 2006. Insects were collected from among nine botanical species: Gochnatia polymorpha (Less.) (cambará), Eugenia uniflora Berg. (pitangueira), Acca selowiana (Berg) Burret (goiaba-da-serra), Psidium cattleianum Sabine (ara á), Baccharis spp., Solanaum mauritianum Scop. (fumo-bravo), Micanea cinerascens Miq. (passiquinho), Calliandra brevipes Bhent. (caliandra), and Schinus molle L. (aroeira) located at Rodolfo da Costa Dam in Itaara, RS, Brazil. Samples were taken every two weeks with a conical funnel made of tin plate (2mm), 70cm in diameter at the rim and 63cm in height. One sample per botanical species for each sampling date was taken, by shaking the branches, ten times over the funnel. Samples were sent to the Entomology Laboratory of the Crop Protection Department of the Federal University of Santa Maria, where the material was analyzed. A total of nine Pentatomidae species were identified. Edessa rufomarginata (De Geer, 1773) was the species of highest ocurrence followed by Thyanta humilis (Bergroth, 1891). The botanical species S. mauritianum presented the greatest number of Pentatomidae species, with an occurrence of 26.9%.

Abstract: Se caracterizó la comunidad de acridomorfos (Orthoptera) a través del análisis faunístico y se determinó el tama o ideal de muestras, en dos áreas del municipio de S o Sepé, RS - Brasil. Los ejemplares fueron obtenidos con el auxilio de una red de recolección, siendo recorridas distancias de 5, 10, 15, 20 y 25 m, a fin de verificar cuál sería la mejor distancia para la colecta de acridomorfos. Las recolecciones fueron realizadas entre enero y mayo de 2009. El cálculo de diversidad fue evaluado a través de los índices de dominancia de Simpson, diversidad de Shannon-Wiener, riqueza de Margalef y equidad de Pielou. Los datos fueron analizados mediante un test no paramétrico de distribución libre chi-cuadrado. El material recolectado representó, 947 acrídidos y 20 proscópidos distribuidos en dos superfamilias,12 géneros y 23 especies. Las especies que presentaron índices elevados de dominio, abundancia, frecuencia y constancia fueron para el área A: Dichroplus silveiraguidoi, Notopomala glaucipes y Scotussa cliens, todas pertenecientes a la familia Acrididae. Para el área B, ocho especies presentaron índices significativos Aleuas vitticollis, Amblytropidia sola, Dichroplus conspersus y Dichroplus silveiraguidoi de la familia Acrididae. El mejor tama o de muestra en términos de precisión estadística fue para 5 m de distancia recorrida. A partir de 25 m se obtuvo el mayor número de individuos y diversidad de especies, pero presentó una elevada desviación estándar y variación. De esta manera, ambos tama os pueden ser recomendados para la obtención de acridomorfos, dependiendo del objetivo del estudio. The research aimed to characterize the community of Acridomorphs through faunal analysis, and to determine the ideal sample size for studies with this group, in two areas from municipality of S o Sepé, RS, Brazil. The specimens were collected by sweep netting, travelling distances of 5, 10, 15, 20 and 25 m, in order to determine which would be the best distance for collecting of acridomorphs. The collections were done between January and May 2009. The calculation of the values of diversity indexes was assessed using the Simpson dominance (D), Shannon-Wiener diversity (H), Margalef richness, and equitability (J’). Data were analyzed by a nonparametric free distribution chi-square test. The collected material represented 947 acridid and 20 proscopids distributed in two superfamilies, 12 genera and 23 species. The species that had high levels of significance in area A were: Dichroplus silveiraguidoi, Notopomala glaucipes and, Scotussa cliens, all Acrididae. In area

Biotemas , 2012,
Abstract: This study aimed to identify the insect that attacks seeds of Cupania vernalis Cambess. and to describe some of its characteristics of predation. In southern Brazil, 754 fruits were collected, from 13 trees, between December 2010 and January 2011. The larvae that were found preying on the seeds were kept in an incubator with a photoperiod of 12h at 25°C, until they reached the adult stage. The microlepidoptera (Lepidoptera, Tortricidae, Olethreutinae) was responsible for the predation of 275 seeds (9.4%), from a total of 2,920 seeds assessed. From each batch of seeds, an average of 5.943g of substrate was consumed, representing 38.2% of the total weight of the seeds.

Abstract: background: there is increasing evidence suggesting that chagas disease involves oxidative damage and contributes to heart disease progression. objective: to evaluate the effect of carvedilol on oxidative stress markers in chronic chagas disease. methods: the study population included 42 patients with chagas cardiomyopathy and oxidative stress biomarkers were measured before and after a period of six months of treatment with carvedilol (37.5 mg/day). patients were considered according to the los andes classification and the activity of superoxide dismutase, catalase, glutathione peroxidase, s-transferase and reductase, myeloperoxidase and adenosine deaminase; levels of reduced glutathione, thiobarbituric acid reactive species, carbonyl protein, vitamin e and nitric oxide were measured in blood. results: after treatment with carvedilol, all groups showed significant reductions in levels of carbonyl protein and reduced glutathione, whereas the levels of nitric oxide and adenosine activity increased significantly only in group ia. moreover, most of the antioxidant enzymes showed decrease in activity in groups ia and ib. conclusion: the data suggest that treatment with carvedilol was effective in attenuating oxidative damage, an effect that may be particularly important in patients with chronic chagas' disease cardiomyopathy.
Diagnostics, rehabilitation and models of Parkinson’s disease  [PDF]

Health (Health) , 2012, DOI: 10.4236/health.2012.431178
Abstract: Diagnostics and rehabilitation of Parkinson’s disease (PD) presents the current information pertaining to etiology, early biomarkers for diagnostics, novel methods to evaluate symptoms, multidisciplinary rehabilitation, new applications of brain imaging and invasive methods to the study of PD. Researchers have only recently begun to focus on the non-motor symptoms of PD, which are poorly recognized and inadequately treated by clinicians. The non-motor symptoms of PD have a significant impact on patient quality of life and mortality, and include cognitive impairments, autonomic, gastrointestinal, and sensory symptoms. Indepth discussion of the use of imaging tools to study disease mechanisms is also provided, with emphasis on the abnormal network organization in parkinsonism. Deep brain stimulation management is a paradigm-shifting therapy for PD, essential tremor and dystonia. In the recent years, new approaches of early diagnostics, training programmes and treatments have vastly improved the lives of people with PD, substantially reducing symptoms and significantly delaying disability. PD results primarily from the death of dopaminergic neurons in the substantia nigra. Current PD medications treat symptoms; none halt or retard dopaminergic neuron degeneration. The main obstacle to developing neuroprotective therapies is a limited understanding of the key molecular mechanisms that provoke neurodegeneration. The discovery of PD genes has led to the hypothesis that misfolding of proteins and dysfunction of the ubiquitin-proteasome pathway are pivotal to PD pathogenesis. Previously implicated culprits in PD neurodegeneration, mitochondrial dysfunction and oxidative stress, may also act in part by causing the accumulation of misfolded proteins, in addition to producing other deleterious events in dopaminergic neurons. Neurotoxin-based models have been important in elucidating the molecular cas-cade of cell death in dopaminergic neurons. PD models based on the manipulation of PD genes should prove valuable in elucidating important aspects of the disease, such as selective vulnerability of substantia nigra dopaminergic neurons to the degenerative process.
