Background: Indoor air quality in environments where there is great circulation of people, posing risks to the health of its occupants, including allergic problems, infections and contaminations, can be aided by climatic factors, chemicals and biological agents housed in these environments, influencing the location and providing favorable conditions for the degradation of bibliographic collections. The present study investigated the presence of fungi in indoor environments in seven public and private libraries in the central region of Brazil, mato grosso, and verified the impact on occupational health. Results: A total of 26,194 fungal specimens were isolated from 342 dust samples collected using three techniques: Andersen’s sampler (12.3%), exposure plate dish (25.1%) and sterile swab (62.6%). A total of 184 fungal species were identified: 156 (84.8%) mycelial fungi and 28 (15.2%) yeast fungi, belonging 54 fungal genera, 43 (79.6%) mycelial fungi and 11 (20.4%) yeast fungi. The genus Aspergillus (40.6%) was one of the main fungi present in indoor air. Aspergillus niger (12.3%) was identified as the most prevalent species in literary environments, followed by Cryptococcus spp. (7.1%) and Cladosporium cladosporioides (7.0%). In relation to seasonal distribution, there was a greater fungal isolation in the dry season (54%);followed by the rainy season (46%). Conclusion: These results suggest the substrates researched in the evaluated environments presented in the form of documents, books and papers associated with dust and air humidity become suitable for microbiological proliferation. These findings highlight the importance of minimizing the risk of exposure to fungal agents, identified in pathogenic and toxigenic microenvironments in library collections.

While clinical data have suggested that the diabetic heart is more susceptible to ischemic heart disease(IHD),animal data have so far pointed to a lower probability of IHD. Thus,the aim of this present review is to look at these conflicting results and discuss the protective mechanisms that conditioned hyperglycemia may confer to the heart against ischemic injury. Several mechanisms have been proposed to explain the cardioprotective action of high glucose exposure,namely,upregulation of anti-apoptotic factor Bcl-2,inactivation of pro-apoptotic factor bad,and activation of pro-survival factors such as protein kinase B(Akt),vascular endothelial growth factor(VEGF),hypoxia inducible factor-1α and protein kinase C-ε. Indeed,cytosolic increase in Ca2+ concentration,the mitochondrial permeability transition pore,plays a key role in the genesis of ischemic injury. Previous studies have shown that the diabetic heart decreased Na+/Ca2+ and Na+/H+ exchanger activity and as such it accumulates less Ca2+ in cardiomyocyte,thus preventing cardiac injury and the associated heart dysfunctions. In addition,the expression of VEGFin diabetic animals leads to increased capillary density before myocardial infarction. Despite poor prognostic in the long-term,all these results suggest that diabetes mellitus and consequently hyperglycemia may indeed play a cardioprotective role against myocardial infarction in the short term.

International Journal of Clinical Medicine 2016年第1期7卷 1-9页

作者： Gabriela De Luccia Karin Zazo Ortiz department of Speech Pathology Federal University of S&atildeo Paulo (UNIFESP) S&atildeo Paulo Brazil University Center of Várzea Grande Mato Grosso Brazil

Acalculia in aphasic patients should be better investigated in order to understand if it is a simple comorbid or if it is influenced by language disorders. This study aimed to compare the performance on EC301 battery calculation tasks between aphasic and normal subjects and sought to verify a possible association between number processing and calculation skills and linguistic changes in aphasic patients, in order to investigate if language disorders interfere with number processing and calculation. Analytical cross-sectional study with a control group, performed of the department of Speech and Hearing Disorders of a public university, conducted in the city of São Paulo, Brazil. First, to analyze the specific difficulties encountered in numerical processing and calculation tasks among the aphasic group, aphasic and healthy adult’s performance in specific calculation tasks were compared. The calculation tasks, which had been badly performed by aphasic patients, were selected. Aphasic patients were also submitted to the language tasks from Montreal-Toulouse Protocol: oral and written comprehension, repetition, reading aloud, naming and dictation. We observed that aphasic individuals showed changes in numerical processing and calculation tasks that were not observed in the healthy population. The most important finding of this study was that aphasic individuals showed changes in numerical processing and calculation that were positively associated to their linguistic performance. The strong associations between battery EC301 and linguistic tasks suggest that language disorders interfere with number processing and calculation.

The linearity, stability, accuracy and inter-day precisions of the assay method were evaluated in methanolic aerial-part extracts of Paepalanthus giganteus and Syngontnhus nitens from the Eriocaulaceae family. Their small capitulae hinder morphological analysis, and thus complicate taxonomic studies of these species, which present anti-ulcer, antimutagenic and antioxidant activities. Taxonomic studies of these plants revealed that the Paepalanthus genus presents flavonols and naphthopyranones while the Syngontnhus genus has flavone and xanthone as majority compounds. The prepared samples were analyzed quantitatively by High Performance Liquid Chromatography with PDA detection for the presence of quercetin, luteolin, 3,6-dimethoxy-1,5,7-tri-hydroxyxanthone and paepalantine. The substances were recovered from these samples at rates from 98.01 to 99.99%. The coefficient of variation in the quantitative analysis of the sample com- pounds was under 5%. The linearity of the method was determined by linear regression. The analysis of the samples spiked with known amounts of analyte demonstrated that the response was proportional to the concentrations of the sam- ples with re-spective determination coefficients of r2 = 0.9999 (luteolin and 3,6-dimethoxy-1,5,7-tri-hydroxyxanthone) and r2 = 0.9998 (quercetin and paepalantine) for the linear range of the analytical calibration curves of the samples. The detection limits were 0.07 μg?mL–1 for quercetin and luteolin, 0.06 μg?mL–1 for 3,6-dimethoxy-1,5,7-tri-hydroxyxanthone and 0.10 μg?mL–1 for paepalantine. The quantification limits were 0.23 μg?mL–1 for quercetin and luteolin, 0.20 μg?mL–1 for 3,6-dimethoxy-1,5,7-tri-hydroxyxanthone and 0.33 μg?mL–1 for paepalantine by LC. The method was considered sen- sitive for quantification of the quercetin, luteolin, 3,6-dimethoxy-1,5,7-tri-hydroxyxanthone and paepalantine in plant samples.

Mitigation of Greenhouse Gas Emissions from Tropical Soils Amended with Poultry Manure and Sugar Cane Straw Biochars

引用

Agricultural Sciences 2017年第9期8卷 887-903页

Increases in greenhouse gases (GHG) emissions, upon changes in land use and agricultural management, lead to a search for techniques that enhance carbon residence time in soil. Pyrolysis increases the recalcitrance of organic materials and enhances their activities as physical, chemical and biological soil conditioners. Emissions of CO2, CH4 and N2O quantified from a sandy soil that was treated with three rates (12.5, 25 e 50 Mg·ha-1) of either non-pyrolysed poultry manure and sugarcane straw or biochars, pyrolysed at two contrasting temperatures (350°C and 650°C). Subsequently, the flux of the three gases was converted and compared in a standard unit (CO2eq). The added biochars, significantly reduced GHG emissions, especially CO2, relative to the non-pyrolysed materials. The greatest differences between applied rates of poultry manure, relative sugarcane straw, both to biochar and raw material, and the positive response to the increase of pyrolysis temperture, confirm the importance of raw material choice for biochar production, with recalcitrance being an important initial characteristic. Greater emissions occurred with intermediate rate of biochars (25 Mg·ha-1) amendment to the soil. These intermediate rates had higher microbial biomass, provided by an intermediate C/N ratio derived from the original soil and the biochar, promoting combined levels of labile C and oxygen availability, leading to an optimal environment for microbiota.

An unusual approach about richness and rarity of leaf-litter ant species is presented here from a dry forest reminiscent in Pantanal province (Chacoan subregion) suggesting the boundaries that defining local and regional scales for this particular ant community. We analysed the frequency of distribution of 170 ant species collected on 262 Winkler’s samples along Serra da Bodoquena National Park, mato grosso do Sul state, Brazil and described some ecological mechanisms that made the species richness estimates be highly influenced by species with low frequencies of records in an extent regional of a pristine dry forest. Bayesian inference was conducted to provide if the probability of latitudinal gradient was correlated with the species richness to define alpha diversity.

Cassava (Manihot esculenta Crantz) is the third largest source of calories in tropical countries and the sixth most important food crop in the World. However, the short shelf life of its storage roots after harvest due to a rapid post-harvest physiological deterioration (PPD) makes the roots to be considered as a risky product to market. The objectives of this work were to investigate the influence of two harvest periods on cassava agronomic parameters and their physiological response to PPD. Three cassava cultivars 96/1414, I070593 and LMR were selected for the experiment and harvested at 10 and 12 months after planting (MAP). The response to PPD was assessed during storage at 0, 3, 8 and 15 days after harvest (DAH). Total proteins content, soluble sugars and starch, total polyphenols compounds, polyphenoloxidase and peroxidase activities were recorded during storage. Results showed large variation among the parameters at the two harvest periods across the cultivars. High number of tubers was recorded in all the cultivars at 12 MAP and a significant increase in storage roots length was observed in 96/1414 and LMR from 10 MAP to 12 MAP (25 ± 5.1 to 41.3 ± 5.9 and 22.6 ± 3.3 to 27.9 ± 4.8) respectively. A reduction of about 49% of tubers weight was observed in I070593 from 10 to 12 MAP while an increase of about 36% and 11% were recorded in LMR and 96/1414 respectively. Tubers from I070593 showed less susceptibility to PPD when harvested at 10 MAP compared to those from LMR and 96/1414 where less susceptibility to PPD were recorded at 12 MAP. An increase in soluble sugars content, total proteins content and peroxidase activity subsequently to a decrease in starch content were recorded during storage from 8 to 15 days after harvest especially at 10 MAP in I070593 and at 12 MAP in LMR and 96/1414. High content of total phenolic compounds and less activity of polyphenol oxidase were correlated to PPD susceptibility. This work opens a new insight issue of the considerati
