Abstract: O objetivo desse estudo foi avaliar a utilidade do SPECT cerebral interictal na localiza o do foco epileptogênico em 23 pacientes do Ambulatório de Epilepsias do Hospital Universitário Clementino Fraga Filho (HUCFF/UFRJ), com epilepsia do lobo temporal (ELT) de difícil controle e tomografia computadorizada (TC) do cranio normal, estudando a correla o entre SPECT interictal, eletrencefalograma (EEG) e, em 11 casos, ressonancia magnética (RM) do cranio, e comparar os resultados com os de outras seis séries da literatura. Doze (52,2%) pacientes apresentaram SPECT anormal. Entre esses, cinco (41,6% dos SPECTs anormais) apresentaram altera o unilateral ao SPECT do mesmo lado do EEG (hipoperfus o em 4 e hiperperfus o em 1), três (25% dos SPECTs anormais) apresentaram hipoperfus o bilateral ao SPECT e altera es também bilaterais ao EEG e 4 (33,3% dos SPECTs anormais) apresentaram hipoperfus o unilateral ao SPECT e EEG bilateral. A análise estatística fundamentou-se na lógica fuzzy. Os índices de correla o entre SPECT X EEG, SPECT X RM e SPECT X EEG X RM foram altamente significativos, com níveis de significancia de 0,01, p < 0,0005 e intervalo de 99% de confian a em todas as correla es. Os estudos de correla o entre as séries estudadas apresentaram resultados semelhantes entre si.

Abstract: a cross section study was carried out in a farming community from nova friburgo, rio de janeiro state, brazil, to examine epidemiological, clinical and laboratory aspects of multiple exposure to pesticides in a representative sample of 102 small farmers. both males and females were submitted to an extensive protocol which included an occupation questionnaire, biological sample collection for toxicology analysis and clinical - general and neurological - evaluation. the toxicology test results showed light to moderate episodes of acute intoxication by organophosphorates either described by the farmers or observed during clinical examination. thirteen cases of delayed neuropathies (12,8%) as well as 29 cases of neural behavioral syndromes and psychiatric disorders associated to the continued use of pesticides were diagnosed. these results indicate recurrent multiple overexposures to high concentrations of different chemicals, with serious damage to vital functions, especially considering their young age (average 35 ± 11 years old) and the productive period in their lifetime. these results show how important it is to monitor multiple exposure to pesticides - a chain of events that may have major impacts on public health and the environment.

Crop Breeding and Applied Biotechnology , 2008,
Abstract: The cultivars Arbequina, Picual and Frantoio of Olea europaea are cultivated in severalMediterranean countries. In 1999, these cultivars were planted at three locations in the region of Coquimbo,an arid, Mediterranean-like area in Chile. A generalized linear modeling approach was used in view of thenon-normal distribution of the agronomic data sets. Fruit yield (harvests of 2002-2003), precocity (2002) andtree survival (after four growing seasons) differed significantly between the cultivars. Arbequina and Picualhad a positive effect on the yield. Picual was the earliest cultivar at two sites. The survival rate of Frantoio washigh at the three sites (90-100%), as opposed to Picual (56-83%). The approach of Generalized Linear Modelswas particularly useful where the assumption of normality was not satisfied. The selection of cultivars ispromising in this arid region of Chile, while the success will depend on the selection of well-adapted genotypesto a particular location.
VEGETATIVE GROWTH AND EARLY PRODUCTION OF SIX OLIVE CULTIVARS, IN SOUTHERN ATACAMA DESERT, CHILE
Freddy MORA,Francisco TAPIA,Carlos Alberto,Elias Nunes
Journal of Central European Agriculture , 2007,
Abstract: Tree survival, early fruit production, vegetative growth and alternate bearing were examined in six different olive cultivars (Barnea, Biancolilla, Coratina, Empeltre, Koroneiki and Leccino) under intensive agronomic conditions i southern Atacama Desert, in the Coquimbo Region of Chile. The cultivars were evaluated over four successive years and had a high survival rate (93%) confi rming their potential for these dry-lands. Fruit production (recorded over the growing seasons 2002-2003), vegetative growth (2000-2003) and alternate bearing differed signifi cantly among cultivars. Olive selection in intensively managed planting at the southern part of the Atacama Desert depends on matching specifi c cultivars to sites on which they perform the best.

Abstract: the olive (olea europaea l.) is an economically important species for countries that have mediterranean climate and has been an appropriate, useful alternative for intensive farming systems in the arid zones of chile. for this reason, the objective of this study was to determine the components of variance, broad-sense heritability, and prediction of genetic values using the bayesian techniques on twenty-eight olive clones in the southern part of the atacama desert. the algorithm of independent chains was used to estimate parameter distributions a posteriori. the field experiment was set up in 2000, and during six years six quantitative traits were monitored in different periods. estimations of heritability and associated credibility intervals (parentheses) were h2=0.50 (0.38-0.61), 0.50 (0.38-0.61), 0.81 (0.74-0.86), 0.53 (0.42-0.64), 0.26 (0.14-0.40), and 0.44 (0.17-0.65) for fruit production (2006), total fruit production (2003-2006), area of trunk cross section (2006), tree productivity (2006), alternation of production (2003-2006), and precocity (2003). genetic advance by direct selection varied from 16 to 55% with a selection intensity of 28.6%. pearson correlations, calculated between genetic values of alternation of production and production traits, were negative and significant. selection of olive clones for precocity would not generate any significant effect on production traits. moderate heritability for fruit production, alternation of production, and precocity suggest a positive response to the selection of olive clones under the environmental conditions of the southern part of the atacama desert.

Abstract: this work aimed to study the variability in flowering of five populations of eucalyptus cladocalyx established in the administrative region of coquimbo, northern chile. flowering was recorded as a binary response trait in 30-month-old trees. then, at first, a generalized linear model was fitted for analyzing provenance effect. subsequently, genetic variability was studied within the best provenance by bayesian inference via gibbs sampling. initially, two sites were considered: caracas and tunga norte, in the littoral and interior area of the choapa province, respectively. in the littoral area, only 1.3% of the trees evidenced flowering events, while in tunga norte, this value was 23.43%. for this reason, only interior site was considered. the provenance effect was significant (p < 0.01), with cowell (codified fdi-20411) being the population that evidenced a relative better flowering response, although it not was different of the trees from national plantations (fdi-illapel). however, trees from a local population evidenced a high variability, having a mean response similar to other provenances. the flowering trait analyzed within the cowell population, the selected provenance, was shown to be highly heritable (h2 = 52.3%). predicted genetic gain when considering two different breeding strategies varied from 36 to 40%. according to these results, it is possible that farmers can recover establishment costs of e. cladocalyx plantations as soon as possible whenever the selected trees are used for apicultural aims

Abstract: O efeito de substitui o do milho pelo resíduo desidratado de fecularia de mandioca (0; 12,5; 22,8 e 32,7%) foi avaliado sobre o desempenho, a digestibilidade e características de carca a e 32 bovinos mesti os ( Nelore x Angus) de aproximadamente 18 meses de idade e 380 kg de peso vivo. O delineamento experimental foi o inteiramente casualizado, com quatro tratamentos e oito repeti es. Foram analisados o ganho médio diário (GMD), rendimento de carca a (RC), espessura de gordura de cobertura (EGC), área de olho de lombo (AOL), comprimento de perna (CP), espessura de cox o (EC), ingest ode matéria seca (IMS), convers o alimentar (CA), digestibilidade total aparente da matéria seca (DAMS), matéria organica (DAMO), proteína bruta (DAPB), energia bruta (DAEB), fibra em detergente ácido (DAFDA) e fibra em detergente neutro (DAFDN). O experimento foidesenvolvido durante um período de 56 dias, após 14 dias de adapta o. Os resultados de GMD, RC, CA, EGC, AOL, CP e EC n o apresentaram diferen as (p > 0,05) entre os tratamentos. A IMS apresentou redu o linear quando o milho foi substituído pelo resíduodesidratado de fecularia de mandioca. Os coeficientes de digestibilidade da MS, MO, PB, EB, FDN e FDA n o variaram entre as ra es experimentais. The effects of replacing corn with different levels of cassava starch by-products (0; 12.5; 22.8; and 32.7%) were evaluated on performance, digestibility and carcass traits of feedlot bulls. Thirty-twocrossbred bulls ( Nelore x Angus) around 18 months of age and 380 kg of body weight were used. A completely randomized design was used, with 4 treatments and 8 replicates. Evaluated traits were: average daily gain (ADG), carcass dressing (CD), backfat thickness (BT), Longissimus area (LDA), leg length (LL) and cushion thickness (CT), dry matter intake (DMI), feed conversion ratio (FCR), total apparent digestibility of dry matter (DMDC), organic matter (OMDC), crude protein (CPDC), crude energy (CEDC), acid detergent fiber (ADFDC) and neutral detergent fiber (NDFDC). The experiment was developed during a period of 56 days, after 14 days of adaptation. No differences wereobserved for BDG, CY, FCR, BT, LDA, LL, and CT results did not present differences (p > 0.05) among the treatments. DMI presented linear decrease as corn was replaced by cassava starch by-products. The digestibility coefficients of DM, OM, CP, CE, NDF and ADF did not vary among the experimental rations.

Abstract: In Brazil, the production of sweet oranges has been threatened by the Citrus Variegated Chlorosis (CVC) incited by the gram-negative bacterium Xylella fastidiosa (Wells). Commercial citrus groves in two counties at the Northwestern Paraná state were evaluated to estimate the disease progression by using parameterizations of nonlinear models. Groves of Citrus sinensis Osbeck, variety “Pêra”, “Valência”, “Natal” and “Folha Murcha” had all the plants evaluated for the presence of disease symptoms. Thereafter, different parameterizations of the Logistic and Gompertz models were fitted to these data. The goodness of fit was evaluated by the intrinsic (IN) and parameter-effects (PE) curvatures of Bates and Watts, the bias of Box and the Hougaard measures of skewness. In Loanda, the best model was the Fermi-Dirac, and in Nova Esperan a the data were best fitted to the parameterization L5, which is also a parameterization from the Logistic model. A citricultura é afetada por diversas doen as, dentre as quais a Clorose Variegada dos Citros (CVC) causada pela bactéria Xylella fastidiosa (Wells). Para a regi o noroeste do Estado do Paraná, onde foi avaliada a CVC, prop e-se encontrar modelos n o-lineares de curvas de progresso de incidência da CVC que representem o percentual de plantas acometidas pela doen a. Para avaliar o comprometimento dos pomares com rela o à doen a, foram escolhidos pomares comerciais em dois municípios, onde foi determinada a propor o de plantas doentes. Foram selecionados talh es de laranja doce (Citrus sinensis Osbeck) nas variedades “Pêra”, “Valência”, “Natal” e “Folha Murcha” e a avalia o de todas as plantas do talh o foi realizada visualmente em rela o à presen a ou à ausência de sintomas de CVC. Para estimar o modelo que melhor se ajustou aos dados de progresso da propor o da doen a em cada talh o, foram considerados modelos n o-lineares decrescimento sigmoidal, o logístico e o de Gompertz, conforme sugerido na literatura. A escolha do melhor modelo foi com base em medidas de curvatura intrínseca e paramétrica de Bates e Watts, viés de Box e medida de assimetria de Hougaard. O modelo que melhor ajustou aos dados de Loanda foi o modelo de Fermi-Dirac e aos dados de Nova Esperan a foi outra reparametriza o do Modelo Logístico, denominado de L5.
