1. Amifostine reduces inflammation and protects against 5-fluorouracil-induced oral mucositis and hyposalivation
Oral mucositis (OM) is a common and dose-limiting side effect of cancer treatment, including 5-fluorouracil (5-FU) and radiotherapy. The efficacy of the therapeutic measures to prevent OM is limited and disease prevention is not fully observable. Amifostine is a cytoprotective agent with a described anti-inflammatory potential. It is clinically used to reduc

2. Efficacy of aqueous garlic extract on growth, aflatoxin B1 production, and Cyto-morphological aberrations of Aspergillus flavus, causing human ophthalmic infection: topical treatment of A. flavus keratitis
By using agar well diffusion assay, antifungal activity of aqueous extract prepared from Egyptian garlic (Allium sativum L.) was evaluated in vitro against two strains of Aspergillus flavus (OC1 and OC10) causing human ocular infection. The recorded minimum inhibitory concentration (MIC) for growth inhibition of both strains was 3.60 mg/ml. Aqueous garlic ex

3. Posicionamento relativo: análise dos resultados combinando as observáveis L1 dos satélites GPS e SBAS. / Positioning on analysis of the results of combining observable L1 GPS satellites and SBAS.
Os sistemas de aumento, conhecidos como SBAS (Satellite-Based Augmentation System) fornecem informações de integridade e acurácia em tempo real para seus usuários, utilizando-se das correções diferenciais que são transmitidas pelos satélites geoestacionários e estão disponíveis em algumas regiões do globo terrestre. Fora da sua região de abrang�

4. Estimação paramétrica e não-paramétrica em modelos de markov ocultos
In this work we study the Hidden Markov Models with nite as well as general state space. In the nite case, the forward and backward algorithms are considered and the probability of a given observed sequence is computed. Next, we use the EM algorithm to estimate the model parameters. In the general case, the kernel estimators are used and to built a sequence

5. Effect of the thickness of the resin cement on the bond integrity and strength of glass fiber fiber-reinforced composite post / Efeito da espessura da camada de cimento na integridade e resistência adesiva de pinos de resina reforçados por fibra de vidro
Debonding is the most common cause of failure reported for glass fiberreinforced composite posts and occurs frequently along the adhesive interface between the resin cement and the root dentin. The ideal thickness of the resin cement to preserve the continuity along the cement-dentin interface and to increase the retention of the post is unknown. The purpose

6. Avaliação do uso de observáveis coletadas com receptores de navegação pessoal para determinação de coordenadas em linhas base curtas / Evaluation of the use of observable collected with receivers, personal navigation coordinates to determine base lines short
In recent decades the use of equipment for positioning, particularly the personal navigation receivers gained relative importance, and the acquisition of these receivers has increased considerably. These eceivers, however, were not developed for task that requiring accuracy, because it estimate and store positions with precision and accuracy of the order of

7. The Dutch of Carambei : a sociolinguistic study / Os holandeses de Carambei : estudo sociolinguistico
Carambeí, a small town in Parana, is Brazil s first Dutch settlement, founded in 1911. In spite of being quite old, it seems as though one has left Brazil when in Carambeí and meeting its people. But what is fact and what is impression? Who are the Carambeienses? Are they Dutch? Are they Brazilian? Do they speak Portuguese? Do they speak Dutch? Which belie

8. Hole of hydrogen peroxide on the interaction of [Vigna unguiculata (L.) Walp] with the fungus Colletotrichum gloesporioides (Penz.) Penz. &Sacc. [Teleomorpho Glomerella cingulata (Stonem.) Spauld. &Von Schrenk] / Papel do perÃxido de hdrogÃnio na interaÃÃo do feijÃo-de-corda [Vigna unguiculata (L.) Walp] com o fungo Colletotrichum gloesporioides (Penz.) Penz. &Sacc. [Teleomorfo Glomerella cingulata (Stonem.) Spauld. &Von Schrenk]
Cowpea is an important legume of the Northeast of Brazil and its yield is affected by Colletotrichum fungi. These fungi are known to occur on and cause disease anthracnose on the broad range of plants. In addition, the rapid and transient accumulation of reactive oxygen species, termed âoxidative burstâ, is one of the earliest observable reaction of plant

9. Heteronuclear NMR investigations of dynamic regions of intact Escherichia coli ribosomes
15N-1H NMR spectroscopy has been used to probe the dynamic properties of uniformly 15N labeled Escherichia coli ribosomes. Despite the high molecular weight of the complex (≈2.3 MDa), [1H-15N] heteronuclear single-quantum correlation spectra contain ≈100 well resolved resonances, the majority of which arise from two of the four C-terminal domains of the

10. Morphological Alterations in Bacillus megaterium as Produced by Aflatoxin B11
Morphologically abnormal cells were produced by Bacillus megaterium NRRL B-1368 in response to aflatoxin B1. Filamentous forms were characterized by early granulation and unusually large and numerous deposits of poly-β-hydroxybutyric acid within the cells. Pantoyl lactone was without effect as a reversing agent for the observed inhibition of cell septum for

11. Blue-Light Regulation of the Arabidopsis thaliana Cab1 Gene.
The steady-state level of Cab RNA in etiolated Arabidopsis thaliana increases as a result of a single pulse of blue light. The threshold for the response is at or below 10[deg] [mu]mol m-2 and begins within 1 h of irradiation. The response is not prevented by far-red treatment, and the blue-light source used does not elicit and observable very low fluence ph

12. Membrane-surfactant Interactions in Lipid Micelles Labeled with l-Anilino-8-naphthalenesulfonate 1
Sonicated lipid micelles, formed from phospholipids isolated from yolks of fresh hen eggs, were used as a model membrane system for studying the effects of several surfactants on membrane properties. The interactions of the surfactants with the model system were followed through the fluorescence of the hydrophobic probe l-anilino-8-naphthalenesulfonate. The
