title: Reproductive phenology of Mauritia flexuosa L. (Arecaceae) in a coastal restinga environment in northeastern Brazil

description: Abstract The buriti, Mauritia flexuosa, is the most common palm in Brazil, where it has considerable ecological and economic importance. However, few data are available on the phenology of the species, mainly in coastal restinga ecosystems. The present study monitored the reproductive phenology of M. flexuosa in the restinga of Barreirinhas, in the Brazilian Northeast, and investigated the relationship between phenophases and climatic variables. The presence/absence of flowers and fruits was recorded monthly in 25 individuals of each sex between August, 2009, and October, 2012. There was no difference in the phenology of male and female specimens, with flowering and fruiting occurring exclusively in the dry season. We believe that the specific abiotic characteristics of the study environment, such as the intense sunlight and availability of water in the soil, contribute to the reproductive success of M. flexuosa in the dry season, with consequent germination and establishment of seedlings occurring during the subsequent rainy season.

title: Neutrophil-lymphocyte ratio in the early diagnosis of sepsis in an intensive care unit: a case-control study

description: ABSTRACT Objective: To evaluate the neutrophil-lymphocyte ratio as a predictor of sepsis and mortality in patients admitted to an intensive care unit. Methods: Case-control study of adult patients admitted to an intensive care unit. Patients who had sepsis as the reason for admission and who had a previous complete blood count examination were included as case patients. The following statistical analyses were performed: ROC curves, binary logistic regression, and Mann-Whitney and Pearson's chi-square tests. p &lt; 0.05 was considered significant. Results: The ROC curve values were 0.62 for neutrophil-lymphocyte ratio, 0.98 for band neutrophils and 0.51 for total leukocytes. The presence of a neutrophil-lymphocyte ratio greater than 5.0, leukocyte count above 12,000mm3/mL and band neutrophil percentage above 10% were risk factors for sepsis; however, only the SAPS 3 and SOFA score were related to patient mortality. Conclusion: The neutrophil-lymphocyte ratio and band neutrophils in combination with other parameters may be markers for the early detection of sepsis in intensive care units.

title: Variation in the prevalence and abundance of acanthocephalans in brown-nosed coatis Nasua nasua and crab-eating foxes Cerdocyon thous in the Brazilian Pantanal

description: Abstract Host infection by parasites is influenced by an array of factors, including host and environmental features. We investigated the relationship between host sex, body size and age, as well as seasonality on infection patterns by acanthocephalan in coatis (Procyonidae: Nasua nasua) and in crab-eating foxes (Canidae: Cerdocyon thous ) from the Brazilian Pantanal wetlands. Between 2006 and 2009, we collected faecal samples from these hosts and analyzed for the presence of acanthocephalan eggs. Prevalence, abundance and intensity of eggs of acanthocephalans were calculated. Egg abundance was analyzed using generalized linear models (GLM) with a negative binomial distribution and models were compared by Akaike criteria to verify the effect of biotic and abiotic factors. Prevalence of acanthocephalans was higher in the wet season in both host species but did not differ between host sexes; however, adult crab-eating foxes showed higher prevalence of acanthocephalan eggs than juveniles. In contrast, prevalence of acanthocephalan eggs found in coatis was higher in coati juveniles than in adults. Host age, season and maximum temperature were the top predictors of abundance of acanthocephalan eggs in crab-eating foxes whereas season and host sex were predictors of egg abundance in coatis. The importance of seasonality for abundance of acanthocephalan was clear for both host species. The influence of host-related attributes, however, varied by host species, with host gender and host age being important factors associated with prevalence and parasite loads.

title: Adverse events during intrahospital transport of critically ill patients in a large hospital

description: ABSTRACT Objective: To describe the incidence of clinical and non-clinical events during intrahospital transport of critically ill patients and to analyze the associated risk factors. Methods: Cohort study with retrospective data collected from October 2016 to October 2017. All cases of intrahospital transport for diagnostic and therapeutic purposes in a large hospital with six adult intensive care units were analyzed, and the adverse events and related risk factors were evaluated. Results: During the study period, 1,559 intrahospital transports were performed with 1,348 patients, with a mean age of 66 ± 17 years and a mean transport time of 43 ± 34 minutes. During transport, 19.8% of the patients were using vasoactive drugs; 13.7% were under sedation; and 10.6% were under mechanical ventilation. Clinical events occurred in 117 transports (7.5%), and non-clinical events occurred in 125 (8.0%) transports. Communication failures were prevalent; however, the multivariate analysis showed that the use of sedatives, noradrenaline and nitroprusside and a transport time greater than 36.5 minutes were associated with adverse clinical events. The use of dobutamine and a transport time greater than 36.5 minutes were associated with non-clinical events. At the end of transport, 98.1% of the patients presented unchanged clinical conditions compared with baseline. Conclusion: Intrahospital transport is related to a high incidence of adverse events, and transport time and the use of sedatives and vasoactive drugs were related to these events.

title: A conflagração do espaço: a tensa relação porto-cidade no planejamento urbano

description: ABSTRACT This paper proposes to motivate a debate on the relation between ports and cities, acknowledging the growing tension that marks the presence of these structures in the urban fabric and its connections with the planning instruments of cities. The paper’s construction started by ascertaining a problem that severely affects some major Brazilian cities, namely, the coexistence of activities of the tertiary and habitation sectors with the ports. The debate was enriched by a theoretical review that sought to establish connections between themes correlated with the problem raised, as well as by official documents from several subnational levels of government. Furthermore, we considered data related to studies and researches developed by actors that operate directly in the ports. It was found that part of this problem derives from an institutional architecture by which the central government creates policies for the port sector without considering the impact these initiatives will have on the urban environment.

title: Height and number of shoots on the survival and development of micropropagated bamboo plantlets during pre-acclimatization

description: ABSTRACT During the in vitro multiplication of bamboo plantlets, it is common the formation of shoots aggregates. Once individualized, these can yield a greater number of plantlets than if planted in clusters. This study aimed to evaluate the effect of the relationship between height and number of initial shoots in micropropagated bamboo plantlets on the survival and development of plants, during the pre-acclimatization stage. Guadua aff. chaparensis shoots, after successive subcultures of in vitro multiplication, were classified into three height classes (2.5-5.0 cm; 5.1-10.0 cm; 10.1-15.0 cm) and number of aggregate shoots (one shoot per plantlet/single-stem plantlet, two and three shoots per plantlet) and pre-acclimatized in a commercial substrate composition plus washed sand. The plantlets were evaluated for survival, height, number of new shoots and roots, shoot and root fresh and dry mass. In plantlets from micropropagation, the plant height does not influence the survival rates, being acclimatized preferably at heights between 5.0 cm and 15.0 cm, with survival rates of up to 97 %. Plantlets with height starting at 5.1 cm and composed of 2 or 3 initial shoots show a greater vigor and ex vitro growth, a fact evidenced by the higher values obtained in relation to height and emission of new shoots and roots, as well as a greater fresh and dry biomass accumulation.

title: Tecnologia Blockchain: inovação em Pagamentos por Serviços Ambientais

description: ABSTRACT Socioecological problems are complex and multidimensional, involving at least an environmental, socio, economic, political and institutional dimensions. Problems related to multiple uses of water resources, watershed revitalization and urban river recovery have placed new challenges on society and require innovative solutions. Proposed solutions, such as payment for ecosystem services (PES), aim to encourage people to adopt actions to solve specific issues in exchange for economic incentives. These solutions have limitations related to continuity of actions after the economic incentives cease. Thus, the main goal of this paper is to introduce and discuss a proposal to manage the Jundiai River Watershed that includes the adoption of a complementary currency created with blockchain technology, the Aqua. The main purposes of this cryptocurrency arethe recovery of riparian forests in rural zones and environmental actions in urban areas. The cryptocurrency Aqua would act as a medium of exchange and circulate only within the network of establishments that accept it. Seeking to avoid the negative consequences of speculative actions, we recommend the Aqua is not convertible into Reais or other cryptocurrencies.

title: Ethnoecology and socioeconomic around an artificial reef: the case of artisanal fisheries from southeastern Brazil

description: Abstract: The objective of this study is to describe the ethnoecological aspects, valorization, and commercialization of target species caught by artisanal fishers on the northern coast of Rio de Janeiro, southeastern Brazil. The data were obtained through semi-structured interviews conducted with 60 fishers from the fishing community of Guaxindiba (21°29'S, 41°00'W), which is associated with the Z-1 fishers' colony. Eighty-nine species were cited by the fishers and 44.1% are important commercial fish in the region. The fishers cited five distinct zones used to fish: border zone (68 species), estuary (41 spp.), artificial reef (27 spp.), "malacacheta" (24 spp.), and open ocean (10 spp.). The fishery resources were classified according to their gastronomic and economic characteristics: primary fish (35 spp.), secondary fish (32 spp.), mixed fish (10 spp.), discarded fish (7 spp.), and fish used as bait (5 spp.). The price of the target species increases along the production chain due to the greater number of people involved, processing costs, and improvement of the product. The data from this study can contribute to local fisheries management and point out to the use of artificial reefs in the maintenance of fishery resources in northern Rio de Janeiro.

title: Surface Topography, Gloss and Flexural Strength of Pressable Ceramic After Finishing-Polishing Protocols

description: Abstract This study evaluated the effect of different finishing-polishing protocols on surface roughness, gloss, morphology and biaxial flexural strength of pressable fluorapatite glass ceramic. Thirty ceramic discs (12x1 mm) were produced and divided into five groups (n=6): CT: control (glaze); DA: fine grit diamond bur; DG: DA + new glaze layer; DP: DA + felt disk with fine grit diamond paste; DK: DA+ sequential polishing with silicon abrasive instruments, goat hair brush and cotton wheel. The specimens were analyzed for surface roughness (Ra) under profilometry and atomic force microscopy (AFM). Gloss was measured with spectrophotometry and micromorphology with scanning electron microscopy (SEM). Flexural strength was assessed by biaxial flexural strength test. Data were analyzed using one-way ANOVA and Tukey’s post hoc test (a=0.05). DK showed the lowest surface roughness values and DA presented the highest in the perfilometer analysis. No significant differences were observed in the AFM for the CT, DG and DK groups, which presented the lower surface roughness; DA and DP had the higher Ra values. The DA, DP and CT showed the lowest surface gloss values, and the reflectance was significantly different from those observed for DK and DG groups. SEM analysis revealed the smoothest surface for DK group, followed by DG and CT groups; DA and DP groups exhibited variable degrees of surface irregularities. No significant differences were observed among groups for the biaxial flexural strength. The polishing protocol used in DK group can be a good alternative for chairside finishing of adjusted pressable fluorapatite glass ceramic surfaces.

title: Antiproliferative and genotoxic effects of nature identical and artificial synthetic food additives of aroma and flavor

description: Abstract This study aimed to analyze the antiproliferative and genotoxic potential of synthetic food flavorings, nature identical passion fruit and artificial vanilla. This assessment used root meristem cells of Allium cepa L., in exposure times of 24 and 48 hours and using doses of 0.2; 0.4 and 0.6 mL. Roots were fixed in Carnoy’s solution, hydrolyzed in hydrochloric acid, stained with acetic orcein and analyzed with optical microscope at 400× magnification, 5,000 cells for each treatment. For data analysis, it was used Chi-square test at 5%. Doses of 0.2 mL at ET 48 h; 0.4 and 0.6 mL at ET 24 and 48 h of passion fruit flavor, and the three doses of the vanilla flavor at ET 24 and 48 h significantly reduced the cell division rate in the meristems of roots, proving to be cytotoxic. Doses of 0.2; 0.4 and 0.6 mL of the passion fruit additive, and the three doses of vanilla tested, in the two exposure times, induced mitotic spindle changes and micronuclei formation in the cells of the test organism used, proving to be genotoxic. Therefore, under the studied conditions, flavoring solutions of vanilla and passion fruit, marketed nationally and internationally, significantly altered the functioning of the cell cycle in root meristem cells of A. cepa.
