2. Constituents of Corynaea crassa "Peruvian Viagra"
Abstract A phytochemical investigation of methanol and n-hexane extracts of tuber/roots of Corynaea crassa Hook. f., Balanophoraceae, led to the isolation and characterization of β-sitosterol, lupenone, β-amyrone, lupeol, and β-amyrine. Unusual complex 1:1 mixtures of lupenone/β-amyrone and lupeol/β-amyrine obtained from the extracts were identified by

3. Bivalent RNA interference to increase isoflavone biosynthesis in soybean (Glycine max)
In this work, a bivalent RNA interference (RNAi) plant-transformation vector was constructed to silence both the flavanone 3-hydroxylase (F3H) gene and the flavone synthase II (GmFNSII) gene in soybean (Glycine max). Two further unit RNAi vectors were constructed for each of these two genes. RNAi-mediated suppression of these genes effectively regulated flav

4. Um estudo econométrico do consumo e da renda agregados no Brasil
A dissertação analisa os dados de consumo e renda das famílias brasileiras entre os anos de 1947 e 2009. O trabalho visa avaliar em que medida o consumo agregado das famílias brasileiras pode ser bem aproximando a partir de um passeio aleatório puro. O trabalho utiliza técnicas de cointegração de Johansen (1988, 1991) e testes de super exogeneidade n

5. Effect of hydrogen on soybean root growth in a subsurface solution.
A vertical split-root technique was used to evaluate the effects of pH levels in a subsurface solution compartment on root development of soybean (Glycine max (L.)Merr.). The surface root compartment (12cm) was filled with limed and fertilized soil. Treatments in the solution compartment were seven pH levels (3.7, 4.0, 4.3, 4.6, 4.9, 5.2, and 5.5) with 2uM C

6. Etiology and epidemiology of Pythium root rot in hydroponic crops: current knowledge and perspectives.
The etiology and epidemiology of Pythium root rot in hydroponically-grown crops are reviewed with emphasis on knowledge and concepts considered important for managing the disease in commercial greenhouses. Pythium root rot continually threatens the productivity of numerous kinds of crops in hydroponic systems around the world including cucumber, tomato, swee

7. Equações de biomassa e estoques de carbono de seis espécies em plantios mistos no noroeste do Mato Grosso
During this time of discussion about global warming and climate change, environmental restoration projects thought as a CO2 sink in its plant biomass are essential in the fighting the increasing concentration of global warming greenhouse gases. One very eficient method to sequester atmosphere carbon is through reforestation and quantifying the resulting stan

8. Influence of luting agents on time required for cast post removal by ultrasound: an in vitro study
OBJECTIVE: This in vitro study evaluated the influence of luting agents on ultrasonic vibration time for intraradicular cast post removal. MATERIAL AND METHODS: After endodontic treatment, 30 roots of extracted human canines were embedded in resin cylinders. The post-holes were prepared at 10 mm depth and their impressions were taken using autopolymerizing a

9. Arbuscular mycorrhizal fungi communities in soil and sugarcane roots / Comunidades de fungos micorrízicos arbusculares no solo e raízes de cana-de-açúcar
Arbuscular mycorrhizal fungi (AMF, Glomeromycota) form mutualistic symbioses with most land plants. AMF hypha generally grow through the soil and colonize the cortical tissue of the plant roots. However, it is not known whether the most abundant species in the soil, determined based on the morphology of asexual spores are the most abundant inside the roots,

10. Distribuição do fósforo no perfil do solo sob sistema plantio direto
The Cerrado, even with soils of low fertility, has been increasing in importance within the Brazilian agricultural scenario, by planning the use and management of land, with the adoption of no-tillage system (NT) and the use of correctives and fertilizers. The application of fertilizers in NT is all doneon the soil surface, which leads to the accumulation of

11. Morphoanatomical characterization of Gentianaceaes species from cerrado and campo rupestre in Minas Gerais / Caracterização morfoanatômica de espécies de Gentianaceae ocorrentes em áreas de cerrado e de campo rupestre em Minas Gerais
The family Gentianaceae presents between 1600 and 1700 species predominantly herbaceous. In Brazil, 25 genera of this family occur mainly in the Cerrado and campos rupestres. The species are included into 6 tribes and 86 genera. The tribe Chironieae presents around 159 species distributed into 23 genera, such as Schultesia and Deianira. The tribe Helieae exh
