Volatile compounds from green and roasted yerba mate were analyzed by gas chromatography/mass spectrometry and the flavor profile from yerba mate beverages was determined by descriptive quantitative analyses. The main compounds tentatively identified in green mate were linalool, alpha-terpineol and trans-linalool oxide and in roasted mate were (E,Z)-2,4-heptadienal isomers and 5-methylfurfural. Green mate infusion was qualified as having bitter taste and aroma as well as green grass aroma while roasted mate was defined as having a smooth, slightly burnt aroma. The relationship between the tentatively identified compounds and flavor must be determined by olfatometric analysis.

Easter egg is a popular chocolate-candy in egg form commercialized in Brazil during Easter time. In this research, Quantitative Descriptive Analysis was applied to select sensory attributes which best define the modifications in appearance, aroma, flavor and texture when cocoa butter equivalent (CBE) is added to Easter eggs. Samples with and without CBE were evaluated by a selected panel and fourteen attributes best describing similarities and differences between them, were defined. Terms definition, reference materials and a consensus ballot were developed. After a training period, panelists evaluated the samples in a Complete Block Design using a 9 cm unstructured scale. Principal Component Analysis, ANOVA and Tukey test (p<0.05) were applied to the data in order to select attributes which best discriminated and characterized the samples. Samples showed significant differences (p<0.05) in all attributes. Easter egg without CBE showed higher intensities (p<0.05) in relation to the following descriptors: brown color, characteristic aroma, cocoa mass aroma, cocoa butter aroma, characteristic flavor, cocoa mass flavor, hardness and brittleness.

Descriptive terminology and sensory profile of three varieties of brazilian varietal white wines (cultivars Riesling, Gewürztraminer and Chardonnay) were developed by a methodology based on the Quantitative Descriptive Analysis (QDA). The sensory panel consensually defined the sensory descriptors, their respective reference materials and the descriptive evaluation ballot. Ten individuals were selected as judges based on their discrimination, reproducibility and individual consensus with the sensory panel. Twelve descriptors were generated showing similarities and differences among the wine samples. Each descriptor was evaluated using a nine-centimeters non-structured scale with the intensity terms anchored at its ends. The collected data were analysed by ANOVA, Tukey test and Principal Component Analysis (PCA). The results showed a great difference within the sensory profile of Riesling and Gewürztraminer wines, whereas Chardonnay wines showed a lesser variation. PCA separated samples into two groups: a first group formed by wines higher in sweetness and fruitty flavor and aroma; and a second group of wines higher in sourness, adstringency, bitterness, alcoholic and fermented flavors.

PURPOSE: To evaluate changes in retinal nerve fiber layer thickness as measured by scanning laser polarimetry (SLP) after the use of medication to reduce intraocular pressure (IOP) in glaucomatous or ocular hypertensive patients. METHODS: The authors prospectively enrolled 37 eyes of 37 patients in whom IOP was reduced by more than 25% after the use of medication. The images were obtained before and 15 to 30 days after the introduction of medication. The SLP parameters measured before and after the use of medication were compared using paired Student's t Test. RESULTS: The mean IOP was significantly reduced from 26.57±4.23 mmHg to 16.54 ±2.92 mmHg after the use of medication (p<0.05). None of the 10 SLP analyzed parameters was significantly affected by the reduction of IOP with medication (p>0.05). CONCLUSION: The retinal nerve fiber layer thickness, as measured by SLP, is not affected by the reduction of IOP with medication in patients with glaucoma or ocular hypertension.

OBJECTIVE: To characterize the behavior of premature newborns in the first year of chronological age. METHODS: This is a cross-sectional descriptive study, bound to a longitudinal study titled: Comparison of visual behavior on the first quarter of year of life of premature nursling born at two maternities of Recife/PE. The sample was composed by 52 premature newborns selected from June, 2007 to June, 2008 from the Maternity of the Federal University of Pernambuco (UFPE). Biological, socioeconomic and demographic data was collected through medical records and interviews with progeny. Newborns were evaluated by the Assessment Guide of Visual Ability in Infants. RESULTS: Most of the newborns were male at a gestational period between 33 weeks and 36 weeks and 6 days, showed a good visual behavior development for the age researched, and most of the families showed good socioeconomical and demographic profile. Besides, it was possible to detect ocular signs in 19% of sample, that were referred to an Ophthalmology Service. CONCLUSION: This study results point out the method like an important key in the early detection and visual screening for premature nursling since the first month of life and it led us to believe that clinical view for occupational therapy intervention must be focused not only on biological risks but also at the influence environment in newborn performance.

OBJETIVO: Investigar a frequência de carcinomas mamários de fenótipo basal em uma série de tumores triplo-negativos (TTN), definidos pela negatividade para receptores de estrógeno (RE), de progesterona (RP) e HER2. MÉTODOS: Selecionamos 140 TTN, obtendo-se características clínico-patológicas e sobrevida. Microarranjo de tecido (2 cilindros de cada tumor) foi construído e submetido à imunoistoquímica para RE, RP, HER2, citoqueratinas (Cks) 5 e 14, EGFR, p63 e p53. Consideramos carcinomas de fenótipo basal os tumores negativos para RE, RP e HER2, e positivos para CK5. RESULTADOS: Encontramos 105 carcinomas de fenótipo basal entre 140 TTN (frequência=75%). A idade média das pacientes foi de 54,8 anos, sendo que 34,3% estavam na pré-menopausa. A maioria dos tumores foi classificada como carcinoma ductal invasor de alto grau. Os TTN exibiram positividade para CK5 (75,0%), CK14 (29%), EGFR (36,4%), p63 (28,6%) e p53 (67,1%). Estadiamento avançado da doença foi observado em 52 pacientes (50%), com diâmetro tumoral maior que 5 cm em 41 casos (39%) e metástases axilares em 61 casos (59,2%). Seguimento clínico foi obtido em 89 pacientes (média=51 meses). Destas, 45 pacientes (50,5%) evoluíram sem doença; 6 (6,7%) estavam vivas com doença e 38 (42,6%) morreram pelo câncer. Recidiva sistêmica ocorreu em 42 pacientes (47,1%), sendo pulmões, cérebro e ossos os principais sítios de metástases. As médias das sobrevidas global e livre de doença foram de 36 e 28 meses, respectivamente. CONCLUSÕES: Nosso estudo confirma comportamento clínico agressivo e elevada frequência dos carcinomas de fenótipo basal entre os TTN, semelhante ao descrito em casuísticas norte-americanas e europeias.

OBJETIVO: avaliar a influência da idade, do sexo, da relação oclusal sagital, do Padrão Facial e de 8 medidas do perfil facial sobre a estética do perfil. MÉTODOS: foram utilizadas tabelas de contingência, o Teste Qui-quadrado e o coeficiente de Cramér para avaliar a possível associação entre a nota dada por 32 avaliadores (14 ortodontistas, 12 leigos e 6 artistas) para a estética do perfil de 100 brasileiros - adultos, leucodermas, portadores de selamento labial passivo - e a idade, o sexo, a relação oclusal sagital, o Padrão Facial e as variáveis da análise facial numérica do perfil. RESULTADOS: não foi observada associação entre a idade, o sexo e a relação oclusal sagital e a estética do perfil facial. A associação foi observada entre a nota recebida para a estética do perfil e o Padrão Facial, o ângulo de convexidade facial e o ângulo do terço inferior da face. CONCLUSÃO: o Padrão Facial, definido na avaliação do perfil pela convexidade do perfil facial, e a projeção anterior do mento foram, entre os fatores avaliados, os determinantes para a estética do perfil facial.

INTRODUCTION: The antibacterial effect of ozone (O3) has been described in the extant literature, but the role of O3 therapy in the treatment of certain types of infection remains controversial. OBJECTIVES: To evaluate the effect of intraperitoneal (i.p.) O3 application in a cecal ligation/puncture rat model on interleukins (IL-6, IL-10) and cytokine-induced neutrophil chemoattractant (CINC)-1 serum levels, acute lung injury and survival rates. METHODS: Four animal groups were used for the study: a) the SHAM group underwent laparotomy; b) the cecal ligation/puncture group underwent cecal ligation/puncture procedures; and c) the CLP+O2 and CLP+O3 groups underwent CLP+ corresponding gas mixture infusions (i.p.) throughout the observation period. IL-6, CINC-1 and IL-10 concentrations were determined by enzyme-linked immunosorbent assay (ELISA). Acute lung injury was evaluated with the Evans blue dye lung leakage method and by lung histology. P<0.05 was considered significant. RESULTS: CINC-1 was at the lowest level in the SHAM group and was lower for the CLP+O3 group vs. the CLP+O2 group and the cecal ligation/puncture group. IL-10 was lower for the SHAM group vs. the other three groups, which were similar compared to each other. IL-6 was lower for the SHAM group vs. all other groups, was lower for the CLP+O3 or CLP+O2 group vs. the cecal ligation/puncture group, and was similar for the CLP+O3 group vs. the CLP+O2 group. The lung histology score was lower for the SHAM group vs. the other groups. The Evans blue dye result was lower for the CLP+O3 group vs. the CLP+O2 group and the cecal ligation/puncture group but similar to that of the SHAM group. The survival rate for the CLP+O3 group was lower than for the SHAM group and similar to that for the other 2 groups (CLP and CLP+O2). CONCLUSION: Ozone therapy modulated the inflammatory response and acute lung injury in the cecal ligation/puncture infection model in rats, although there was no improvement on survival rates.

Estudo descritivo e de corte transversal que objetivou conhecer as características do abuso sexual em crianças e adolescentes de zero a 14 anos, a partir dos casos registrados nos Conselhos Tutelares e programas de atendimento do município de Londrina-PR, em 2006. Os dados foram coletados por meio de formulário e posteriormente analisados por frequência (absoluta e relativa) e proporção. Dos 186 casos, as vítimas foram predominantemente do sexo feminino (74,2%) e o risco de incidência foi maior na idade de 10 anos entre as meninas (coeficiente de cinco por 1.000); 97,3% dos agressores eram do sexo masculino; maior parte dos abusos ocorreu na residência das vítimas (52,7%) e durou menos de seis meses (57%). Houve lesão corporal em 90,3% dos casos, com seqüela física e psicológica em 97,8%. O abuso sexual entre crianças e adolescentes constitui-se um problema de saúde pública, além da estreita interface com as questões policiais e jurídicas.

OBJETIVO: Avaliar as concentrações séricas de retinol e beta-caroteno de pré-escolares em Teresina, Piauí, com caracterização do perfil antropométrico e do consumo alimentar. MATERIAL E MÉTODOS: Estudo transversal envolvendo 135 crianças em creche municipal, com avaliação do estado nutricional pelos métodos: bioquímico (concentração sérica de retinol e beta-caroteno), antropométrico (índices de peso para estatura - P/E e estatura para idade - E/I) e dietético (freqüência de consumo alimentar). RESULTADOS: Observou-se prevalência de deficiência de vitamina A (DVA) de 8,9% (IC95%: 4,7 - 15,0%) e existência de associação entre suplementação anterior e concentrações de retinol, com maior proporção de crianças com níveis normais de retinol entre as suplementadas (p = 0,025). As concentrações de retinol e de beta-caroteno mostraram-se correlacionadas, porém com força leve a moderada (p < 0,021). Os percentuais de crianças com baixo P/E e de baixa E/I foram de 1,9% (IC95%: 0,2 - 6,8%) e 9,7% (IC95%: 4,8 - 17,1%), respectivamente. Na avaliação dietética verificou-se baixo consumo de alimentos ricos em vitamina A. CONCLUSÕES: A elevada prevalência de DVA nas crianças, combinada com a alta percentagem de crianças com valores aceitáveis de retinol, os baixos valores medianos de beta-caroteno, a alta percentagem de déficit estatural e a inadequação do consumo de alimentos ricos em vitamina A, indicam a necessidade de se aprimorar as estratégias de educação em saúde e nutrição da população, incentivando o consumo de alimentos fontes de vitamina A, como medidas auto-sustentáveis importantes no combate ao problema. Além disso, deve ser considerado o incentivo à fortificação dos alimentos e ao fortalecimento de Programas de suplementação.
