Fungal endophytic species inhabiting the leaves of eucalypts are capable of utilising leaf sugars and can influence both plant growth and health. Endophytic fungal symbionts can use simple soluble sugars in leaves as their main carbon source. This study set out to determine the diversity and distribution of the endophytic filamentous fungal leaf community in the hybrid Eucalyptus urograndis due to its economic importance. The fungal leaf community was characterised using denaturing gradient electrophoresis (DGGE) and correlated with levels of leaf nutrients and sugars throughout plant development. Sequencing of DGGE bands revealed the presence of Basidiomycota and Ascomycota phyla. Fourteen species and three genera of filamentous fungi were identified, and the population structure was affected by the plant developmental stage. Levels of K, Cu, N and Mn influenced communities from the clonal garden, whereas leaves in the field had higher glucose, fructose and sucrose. Many fungi were found to be specific to a certain development stages: Diplomitoporus crustulinus, Podosphaera tridactyla and Aspergillus restrictus to the clonal garden stage;Chaetomella acutiseta and Ascotricha chartarum to the shading stage;Erratomyces patelii and Saxomyces sp. to the shading output stage;Lepidostroma sp. and Saxomyces sp. to the dispatch stage;and Mycosphaerella populicola to the field stage. Teratosphaeria toledana and Teratosphaeria acidotherma were found at more than one developmental stage. Cladosporium sp. and Rhodosporidium fluviale colonized and persisted in plants at the dispatch and field stages. This is the first report of P. tridactyla, A. restrictus, E. patelii, Saxomyces and Lepidostroma sp. as endophytes in eucalipt.

AIM： TO evaluate the impact of hepatitis C virus （HCV） infection with genotype 1 or 3 and the presence or absence of liver cirrhosis （LC） in the early viral kinetics response to treatment. METHODS： Naive patients （n = 46） treated with interferon-α （IFN-α） and ribavirin and followed up with frequent early HCV-RNA determinations were analysed. Patients were infected with genotype 1 （n = 28, 7 with LC） or 3 （n = 18, 5 with LC）. RESULTS： The first phase decline was larger in genotype 3 patients than in genotype 1 patients （1.72 vs 0.95 log IU/mL, P 〈 0.001）. The second phase slope decline was also larger in genotype 3 patients than in genotype 1 patients （0.87 vs 0.15 log/wk, P 〈 0.001）. Differences were found in both cirrhotic and non-cirrhotic patients. Genotype 1 cirrhotic patients had a slower 2^nd phase slope than non-cirrhotic patients （0.06 vs 0.18 log/wk, P 〈 0,02）. None of genotype 1 cirrhotic patients had a 1^st phase decline larger than 1 log （non-cirrhotic patients： 55%, P 〈 0.02）. A similar trend toward a slower 2nd phase slope was observed in genotype 3 cirrhotic patients but the 1^st phase slope decline was not different. Sustained viral response was higher in genotype 3 patients than in genotype 1 patients ,（72% vs 14%, P 〈 0.001） and in genotype 1 non-cirrhotic patients than in genotype 1 cirrhotic patients （19% vs 0%）. A second phase decline slower than 0.3 log per week was predictive of non-response in all groups. CONCLUSION： Genotype 3 has faster early viral decline than genotype 1. Cirrhosis correlates with a slower 2nd phase decline and possibly with a lower 1^st phase slope decline in genotype 1 patients.

The objective was to identify the most frequent nursing diagnoses labels in patients with liver cirrhosis in use of feeding tube. A descriptive research was carried out in a Brazilian Hospital with 20 adult patients. Systematic data collection utilized the Conceptual Model of Wanda Horta, the first nurse to introduce the concept of Nursing Process in Brazil. The six phases of the nursing diagnostic reasoning proposed by Risner were used;nursing diagnoses were described according to NANDA-I taxonomy II. Patients were mainly male;half of them were middle age adults;they had an average of 12.8 nursing diagnoses labels;and the most frequent were: risk for aspiration and risk for infection. Nurses needed to develop effective skills to properly diagnose in order to provide safe care and improve patient outcomes.

Agglomerates based on milk whey proteins and modified starch (MS) were developed for patients with dysphagia. Calcium caseinate (CaCas), whey protein isolate (WPI), concentrate (WPC) and hydrolysate (WPH) were used. The sources were agglomerated with the MS and an increase in the porosity and viscosity of the agglomerates were observed. In all the systems evaluated, the WPI agglomerate at a concentration of 112 g/L showed a viscosity between 2122 and 5110 cP, and the agglomerates of WPC and WPH between 1115?-?2880 cP and 2600 - 6651 cP, respectively. CaCas exhibited high values in water and milk of 3200 cP and 6651 cP, respectively, and low values of 640 cP in juice. In sensory tests, the 70% WPI: 30% MS juice obtained a score 6.97, an improvement in relation to the other agglomerates, but not differing (p = 0.681) from the commercial thickener, 6.91 (p = 0.380). Based on these results, the 70% WPI: 30% MS was suggested for use in the nutritional therapy of patients with dysphagia.

Furthermore, regarding INDEL association with relapse risk, the Ins alleles of ACE, HLAG, and UGT1A1 were associated with early relapse risk, as well as the Del allele of TYMS.

Seasonal Influence in Traffic-Related Air Pollutants Concentrations in Urban Parks from Porto Alegre,Brazil

引用

Open Journal of Air Pollution 2019年第4期8卷 96-107页

作者： Bruna Marmett Roseana Boek carvalho fernanda Ramos Rhoden Cláudia Ramos Rhoden Laboratory of Atmospheric Pollution Graduate Program in Health ScienceFederal University of Health Sciences of Porto Alegre(UFCSPA)Porto AlegreBrazil

Traffic-related air pollution is an alarming source of pollutants exposure and consequently to the development of several adverse health effects. Otherwise, green spaces are reported to improve health status. Although, in an urban scenario most of these areas are located near air pollutants sources, as vehicle fleet. Thus, the aim of the present study was to determine, during one year, the levels of nitrogen dioxide (NO2) and ozone (O3) in the main parks from Porto Alegre—Brazil. This study focused on three urban parks: Germania, Moinhos de Vento and Marinha do Brasil Park. Nitrogen dioxide and ozone measurements were accessed by passive monitoring in four campaigns including all seasons and performed at distances of 0 m, 15 m, 30 m, 45 m, 60 m and 75 m from the main road at each park. NO2 and O3 concentration among the parks was not different (p > 0.05), as well as the mean concentration of NO2 and O3 of all parks in the six sites did not differ (p > 0.05). However, season 1 and 3 showed increased NO2 and O3 concentration. Temperature were decreased in season 1 and 3 (p p > 0.05). Traffic flow was higher in Moinhos de Vento Park and Marinha do Brasil Park compared to Germania Park (p 2 and O3 concentration in urban parks from Porto Alegre.
