1. Soybean extracts enriched with free isoflavones promote nitric oxide synthesis and affect the proliferation of breast adenocarcinoma cells
Although soybean isoflavones naturally accumulate in their conjugated forms, the beneficial effects on human health of soybean-containing foods have been credited to their aglycone forms. In the present study we analyzed the effects of a chemical agent, sodium nitroprusside (SNP), in eliciting the exudation of non-conjugated isoflavones from intact soybean s

2. Efeito do número de Reynolds e da razão de equivalência na emissão de NOx em chama difusiva turbulenta / Effects of the Reynolds number and equivalence ratio on the NOx emission on turbulent diffusion flame
Este estudo relata uma análise, baseada em dados experimentais, da distribuição de emissão dos Óxidos de Nitrogênio (NOx) em uma chama difusiva turbulenta vertical que utiliza 12 pequenas chamas piloto para ancorá-la. A idéia básica consiste na variação da dinâmica do escoamento e posterior observação do comportamento espacial das espécies qu�

4. Estudo dos efeitos da inibiÃÃo crÃnica do Ãxido nÃtrico na reproduÃÃo de ratos machos / Study of the effect of the chronic inhibition of nitric oxide in the reproduction of male rats
Nitric Oxide (NO) derived from L-arginine by the nitric oxide synthase (NOS) which is expressed by various isoforms, is considered to be na important messenger molecule in several organ systems including the male genital tract. This study analysed the possible effects of L-NAME (NG-nitro-L-arginine methyl ester), a nonselective NOS inhibitor on testicilar de

5. Nitric oxide donor-mediated killing of bioluminescent Escherichia coli.
The antimicrobial activities of two nitric oxide-releasing compounds against Escherichia coli were investigated by using recombinant E. coli cloned with a luciferase gene from Pyrophorus plagiophthalamus. Since luciferase uses intracellular ATP to generate visible light which can be measured from living cells in real time, we wanted to compare the extent to

6. Newly Recognized Vital Nitrogen Cycle
Soil and sea bacteria produce a small amount of nitrous oxide (N2O); a small part of this N2O is photochemically converted to nitric oxide (NO) in the stratosphere. This process has recently been shown to be the principal source of the active oxides of nitrogen (NO and NO2) in the stratosphere. The active oxides of nitrogen catalytically destroy ozone, and N

7. Arabidopsis Nonsymbiotic Hemoglobin AHb1 Modulates Nitric Oxide Bioactivity
Nitric oxide (NO) is a widespread signaling molecule, and numerous targets of its action exist in plants. Whereas the activity of NO in erythrocytes, microorganisms, and invertebrates has been shown to be regulated by several hemoglobins, the function of plant hemoglobins in NO detoxification has not yet been elucidated. Here, we show that Arabidopsis thalia

8. Contributions of Autotrophic and Heterotrophic Nitrifiers to Soil NO and N2O Emissions †
Soil emission of gaseous N oxides during nitrification of ammonium represents loss of an available plant nutrient and has an important impact on the chemistry of the atmosphere. We used selective inhibitors and a glucose amendment in a factorial design to determine the relative contributions of autotrophic ammonium oxidizers, autotrophic nitrite oxidizers, a

9. A tautomeric zinc sensor for ratiometric fluorescence imaging: Application to nitric oxide-induced release of intracellular zinc
Zinc is an essential metal ion for human growth and development, the disruption of cellular Zn2+ homeostasis being implicated in several major disorders including Alzheimer's disease, diabetes, and cancer. The molecular mechanisms of Zn2+ physiology and pathology are insufficiently understood, however, owing in part to the lack of tools for measuring changes

10. Role of Nitric Oxide Synthase in the Light-Induced Development of Sporangiophores in Phycomyces blakesleeanus
Blue light controls the development of sporangiophores in the zygomycete Phycomyces blakesleeanus Burgeff. Light represses the production of microsporangiophores and enhances the development of macrosporangiophores. Inhibition of the biosynthesis of tetrahydrobiopterin, a cofactor of NO synthase, inhibits this photomorphogenesis. Light induces production of

11. Relative Rates of Nitric Oxide and Nitrous Oxide Production by Nitrifiers, Denitrifiers, and Nitrate Respirers
Biogenic emissions of nitric and nitrous oxides have important impacts on the photochemistry and chemistry of the atmosphere. Although biogenic production appears to be the overwhelming source of N2O, the magnitude of the biogenic emission of NO is very uncertain. In soils, possible sources of NO and N2O include nitrification by autotrophic and heterotrophic

12. Vascular endothelial dysfunction resulting from l-arginine deficiency in a patient with lysinuric protein intolerance
Although L-arginine is the only substrate for nitric oxide (NO) production, no studies have yet been reported on the effect of an L-arginine deficiency on vascular function in humans. Lysinuric protein intolerance (LPI) is a rare autosomal recessive defect of dibasic amino acid transport caused by mutations in the SLC7A7 gene, resulting in an L-arginine defi
