Last month a new study commissioned by the British Library and the Joint Information Systems Committee (JISC) issued one of those “Duh!” reports. The new study (available here http://www. bl.uk/news/pdf/googlegen.pdf) found that the “Google Generation,” or those brought up by computer wolves, is not very Web-literate.

The plant-parasitic nematodes are responsible for serious injuries in roots and shoots of ornamental plants, reducing its beauty and consequently its economic value. This study aimed to ascertain the occurrence and distribution of plantparasitic nematodes through the analysis of the roots of ornamental and flowering plants at UNESP FCAV's landscape. The roots were collected from fifteen different species as follows: Anthurium andreannum, Rhododendron simsii, Impatiens walleriana, Calathea stromata, Cordyline terminalis, Dieffenbachia picta, Dracaena marginata, Ficus benjamina, Spathiphyllum ortgiesii 'Sensation', Spathiphyllum wallisi 'American Beauty' and 'Mini', Odontonema strictum, Portulaca grandiflora, Strelitzia reginae, Tradescantia zebrina and Tradescantia pallida. Samples of roots were processed. The plant-parasitic nematodes identified in the samples were: Meloidogyne sp. (Anthurium andreannum, Calathea stromata, Dieffenbachia picta, Ficus benjamina, Impatiens walleriana, Odontonema strictum, Portulaca grandiflora, Spathiphyllum ortgiesii 'Sensation'), Helicotylenchus dihystera (Calathea stromata, Dracaena marginata, Portulaca grandiflora, Spathiphyllum ortgiessi 'Sensation', Tradescantia pallida, Tradescantia zebrina), Tylenchus sp. (Anthurium andreannum, Calathea stromata, Cordyline terminalis, Dieffenbachia picta, Ficus benjamina, Rhododendron simsii), Aphelenchoides sp. (Dieffenbachia picta, Spathiphyllum ortgiesii 'Sensation', S. wallisi 'American Beauty'), Rotylenchulus reniformis (Cordyline terminalis, Dracaena marginata, Odontonema strictum), Pratylenchus sp. (Spathiphyllum ortgiesii 'Sensation', Spathiphyllum wallisi 'Mini'), Ditylenchus sp. (Spathiphyllum wallisi 'Mini'), Pratylenchus brachyurus (Tradescantia zebrina). The plant-parasitic nematodes weren't found in the roots of Strelitzia reginae.

The aim of this work was to evaluate the population density of Pratylenchus brachyurus and Pratylenchus zeae associated with Brachiaria brizantha, B. decumbens and B. humidicola and their influence on forage availability and quality. The experiment was conducte in the Hisaeda Farm, Terenos, MS, Brazil. Soil, roots and plant aerial part were harvest with ten replications each, in one square meter randomized sets encompassing three treatments: Good, Intermediary and Bad, visually characterized, considering the percentage of green material. P. brachyurus and P. zeae density were evaluated in soil and plant roots. Dry matter of green, dead and re-growth materials, plant nutritional status and forage quality were assessed in the aerial plant part. Soil fertility was determined in all harvested samples. Both nematode species were identified from all samples, with a larger numbe in the roots (between 87-311 P. brachyurus and 1-61 P. zeae.10 g-1) than in the soil (0-8 P. brachyurus and 1-39 P. zeae.200 cm-3), however, no significant differences were found in the number of specimens between treatments. Considering that these forage species are perennial and host Pratylenchus spp, there is a tendency to increase the population of these pathogens over time, becoming a serious phytosanitary problem.

Study Design: Prospective study Objective: To evaluate the effect of a protocol of concurrent training lasting 16 weeks on risk factors for the accumulation of hepatic fat in obese youth. Methods: 38 obese children and adolescents of both sexes, between 12 and 15 years old. The obesity was attested by the percentage of body fat, which was estimated by dual-energy X-ray absorptiometry (DEXA). Additionally, the amount of fat located in the trunk (kg) was estimated too. Before and after the intervention, the youths underwent biochemical blood tests (fasting complete lipid profile [mg / dL]) and ultrasonography of the liver (right size Wolves [LD cm] and left [LE in cm]). The intervention consisted of concurrent training (strength training [30 minutes] and endurance training [30 minutes]) with three sessions per week, totaling 180 minutes a week, for ten weeks. Statistical analysis was made by the test t of Student for paired data using SPSS software (17.0) and significance statistical fixed at p <5%. Results: After the intervention, significant improvements were observed in the percentage of total fat (PRE: 45.1 ± 5.3 and POST: 41.7 ± 5.6, p = 0.001) and in the trunk region (PRE: 46, 5 ± 5.6 and POST: 42.9 ± 6.3, p = 0.001). For lipid profile, reduction in total cholesterol (PRE: 164 ± 34 and POST: 148 ± 29, p = 0.001), triglycerides (PRE: 118 ± 59 and POST: 104 ± 53, p = 0.002) and lipoproteins density (PRE: 100 ± 29 and POST: 85 ± 26, p = 0.001), but not for high-density (p = 0.981). Both the LE (PRE: 8.8 ± 1.4 and POST: 7.8 ± 1.3, p = 0.001) and LD (PRE: 13.6 ± 1.3 and POST: 12.9 ± 1, 1, p = 0.001) experienced a decrease in its proportions. Conclusion: The concurrent training was effective in combating some risk factors to the accumulation of fat in the liver, as well as in reducing fat in both lobes of the organ in young obese.

Liophis typhlus (Linnaeus, 1758) é uma espécie de distribuição restrita à América do Sul, sendo reconhecida três subespécies: Liophis typhlus typhlus encontrada nas florestas tropicais ao longo da bacia Amazônica, nos seguintes países: Equador, Bolívia, Colômbia, Peru a Leste dos Andes, Norte e Leste da Venezuela, Guianas e Brasil; Liophis typhlus brachyurus presente na Mata Atlântica do Sudeste e nos cerrados do Centro-oeste brasileiros e no Paraguai; e Liophis typhlus elaeoides presente na bacia do Rio Paraguai, incluindo os Chacos do Sudeste da Bolívia, Norte do Paraguai e Centro-Oeste do Brasil. Com o objetivo de revisar taxonomicamente Liophis typhlus foram analisados 16 caracteres morfométricos e 19 merísticos de 240 espécimes. A osteologia craniana e a morfologia hemipeniana foram analisadas de forma comparativa entre os táxons. Foram identificadas diferenças sexuais significativas, utilizando o teste t. Foram realizadas Análises de Função Discriminante entre os espécimes dos táxons estudados, com o intuito de analisar se, de maneira multivariada, as amostras são diferentes entre si e quais as variáveis que estariam contribuindo para esta separação, a Análise de Variância (MANOVA) foi utilizada entre os táxons, para verificar diferenças significativas entre eles. Foi evidenciada diferença significativa entre machos e fêmeas dos exemplares de L. t. elaeoides, com relação à VE, em L. t. typhlus foram evidenciadas diferenças significativas com relação a seis caracteres (CT, CCA, LCA, LFR, CMA e VE). Os resultados das análises da Função Discriminante indicaram uma clara distinção, num espaço multivariado, entre os três táxons estudados. O padrão de coloração, a morfologia hemipeniana e craniana foram importantes na diagnose das espécies. A distribuição de L. typhlus, parece estar restrita ao domínio Amazônico, tendo seu limite setentrional no norte do Mato- Grosso próximo à área de transição Amazônia-Cerrado. L. rachyurus está mais associado ao domínio Cerrado, porém ocorre em áreas de Mata Atlântica, Caatinga e Pantnal. L. elaeoides possui uma área de distribuição mais restrita associada ao Chaco e Pantanal, contudo sua distribuição foi ampliada, com análise de dois exemplares procedentes do Rio Grande do Sul. Não foi possível verificar as relações filogenéticas entre as espécies L. brachyurus, L. elaeoides e L. typhlus com as demais espécies do gênero.
