title: Biomass, Carbon and Nitrogen in the Accumulated Litter of Planted and Native Forests

description: ABSTRACT This study aimed to evaluate the biomass, carbon and nitrogen stocks in accumulated litter in a Semidecidual Seasonal Forest fragment and two pure forest plantations (Pterogyne nitens and Eucalyptus urophylla), located in the Southwest of Bahia. Litter samplings were carried out in the rainy and dry season. The biomass from accumulated litter was higher in eucalyptus stand (13.1 Mg ha–1) and lower in the Pterogyne nitens (1.5 Mg ha–1), reaching intermediate values in the native forest (6.3 Mg ha–1). This same sequence was checked for carbon stocks: 5.6 Mg ha–1 (eucalypt) 2.7 Mg ha–1 (native forest) and 0.6 Mg ha–1 (P. nitens). The P. nitens stand has N content of leaf’s litter compatible to the native forest. The greatest differences in biomass, carbon and nitrogen of accumulated litter between the rainy and dry seasons were found in pure stands.

title: Degradation of 17α-methyltestosterone by hydroxyapatite catalyst

description: Abstract Fish farming is becoming a highly profitable economic activity and the rearing of fingerlings involves the practice of sex reversal for the production of species (male) using the hormone 17α-methyltestosterone (MT). This study analyzed the methodology for degradation of the hormone through solar and ultraviolet radiation using hydroxyapatite (HAP) as heterogeneous catalyst, synthesized by two different methods, with and without doping with nickel and copper. The results showed that MT hormone is degraded by ultraviolet or solar radiation, and accelerated in the presence of the HAP catalyst. In the presence of Fe (III) in the medium, the degradation rate of the hormone decreases. The method of HAP synthesis influences the degradation efficiency.

title: ANTIMICROBIAL ACTIVITY OF YERBA MATE (Ilex paraguariensis) EXTRACT AGAINST MICROORGANISMS ISOLATED FROM CHICKEN MEAT

description: Abstract Yerba mate has been studied due to the biological activities already evidenced. This study aimed to evaluate the antimicrobial effect of the addition of yerba mate extracts against Escherichia coli and Proteus mirabilis previously isolated from chicken breast meat using the disk diffusion method. Different extract concentrations were applied (125 mg/mL, 250 mg/mL, 550 mg/mL of yerba mate extract, negative control with saline 0.85% and pure yerba mate) in triplicate and the results were analyzed by the SAS® 5.1. The increase in the concentration of the extract applied resulted in an increase (P&lt;0.0001) in the inhibition zone formed for both bacteria, and it was evident that the inhibition zone for E. coli was smaller compared with the halos for P. mirabilis. It was possible to estimate the concentration of 400 mg/mL as the most efficient for both bacteria.

title: Performance assessment of imported ELISA in the serodiagnosis of the enzootic bovine leukosis in herds of Pernambuco state, Brazil

description: ABSTRACT: Enzootic bovine leukosis (EBL) is an infectious disease of cosmopolitan distribution and chronic character caused by a virus of the Retroviridae family, bovine leukemia virus (BLV). The epidemiological situation of EBL in Brazil has motivated studies to improve its diagnosis, based on the recommended serological techniques: agar gel immunodiffusion (AGID) and enzyme-linked immunosorbent assay (ELISA). This study was designed to evaluate the use of imported ELISA for the detection of BLV in dairy herds raised in Pernambuco, Brazil, comparing it to AGID. Blood serum samples from 327 dairy cattle from the state of Pernambuco were tested to AGID and the imported commercial ELISA CHEKIT-Leucose-serum, produced by the IDEXX® laboratory for the diagnosis of EBL. Discarding 25 inconclusive samples from one or both tests, 302 samples were analyzed, being 24.1% positive (73/302) in the AGID and 45% (136/302) in the ELISA, which compared to the AGID, a technique considered standard, presented sensitivity of 98.6%, specificity of 72% and Kappa coefficient of 0.55. The lack of agreement in the diagnostic methods was probably due to the high sensitivity of the ELISA, which makes it possible to detect antibodies even in situations with low serum levels. Although AGID has been shown to be an efficient test so far, in more advanced stages of an EBL control and eradication program, with low prevalence rates, ELISA will present better performance, due to its higher sensitivity, avoiding the permanence of animals that spread the disease in the herds.

title: Quality pattern evaluation of frozen soursop pulps: an assessment based on chemical composition and chemometric analysis

description: Abstract In the present study, the physicochemical properties and mineral composition of commercially-frozen soursop pulps from the southern region of the state of Bahia, Brazil, were evaluated. The physicochemical parameters such as soluble solids (°Brix), acidity and pH were determined according to reference methodologies. For mineral composition evaluation, samples were digested in a closed microwave system and the elements K, P, S, Ca, Mg, Fe, Cu, Zn, and Mn were quantified through inductively coupled plasma optical emission spectrometry (ICP OES). Soluble solids content ranged from 4.77 to 15.37 °Brix among the different brands of analyzed frozen pulps. Titratable acidity (equivalent to citric acid) and pH ranged from 0.49 to 1.00 and 3.61 to 4.57, respectively. Some samples presented irregularities in regard to quality pattern established in the Brazilian legislation. The following range of concentration, in μg g-1, were found for essential elements: K (544-1761), P (44.3-139), S (71.8-174), Ca (24.3-77.0), Mg (47.2-132), Fe (1.40-4.05), Mn (0.32-1.22), Cu (0.30-0.88) and Zn (0.36-0.84). The use of principal component analysis (PCA) enabled a more in-depth data analysis, performing correlations between different variables and frozen pulp brands.

title: Risk factors for short-term absenteeism in medium-sized hospital

description: Abstract Introduction Even though there are evidences of absenteeism in the hospital context, more studies are needed beyond the care sector. Objectives to investigate the associations between the prevalence of absenteeism of three sectors employees of a philanthropic medium-sized hospital and individual characteristics, life habits, health status and working conditions. Method Cross-sectional study with random sample of 123 professionals from care, administrative and support sectors. The data was collected through a self-administered questionnaire that included information on absence from work, socio-demographic, habits and lifestyle characteristics, health status and working conditions. Prevalence ratios of absenteeism and their respective 95% confidence intervals were adjusted by Poisson multivariate regression. Results The prevalence of absenteeism due to sickness in last 12 months was 28.5% and it was associated with high physical and psychological demands, working time at the hospital and presence of occupational diseases. Conclusion Precarious working conditions are associated sickness absenteeism among professionals investigated. This finding must be considered in the formulation of interventions involving the health promotion of these workers.

title: Clinical engineering: a new “bridge” for bioethics?

description: Abstract This case study was based on a performance analysis of the hospital services offered by Dom Orione Hospital, in Araguaína/TO, Brazil, as a result of the structuring of the department of Clinical Engineering in the institution, in which 70% of the services provided are aimed at patients from the Brazilian Unified Health System. The increase achieved in the amount of care provided and in the quality of services offered points to the social nature of this institutional structuring process, noting both its convergence with the principles and values espoused by bioethics, whether from the clinical perspective regarding the social theoretical model, or as it suits the assumptions that guide the Brazilian Unified Health System itself.

title: Adaptive morphoanatomy and ecophysiology of Billbergia euphemiae, a hemiepiphyte Bromeliaceae

description: Abstract Habitats under distinct selective pressures exert adaptative pressures that can lead individuals of the same species to present different life strategies for their survival. The aim of this study was to analyse morphoanatomical and physiological traits for identification of adaptive ecological strategies related to both terrestrial and epiphytic life phases of Billbergia euphemiae. It was verified that B. euphemiae showed lower height, as well smaller length, width and foliar area in epiphytic phase than in terrestrial phase. Concerning to foliar anatomy, the thicknesses of leaf and water-storage parenchyma were higher in terrestrial phase, as densities of stomata and scales on the abaxial surface were higher in epiphytic phase. About the contents of photosynthetic pigments, only chlorophyll a/b ratio showed differences between life phases. In both habits, plants exhibited roots with absorption hair. In epiphytic phase, roots exhibited higher velamen thickness, smaller outer cortex, higher number of inner cortex cell layers and higher number of protoxylem poles. Thus, B. euphemiae individuals in epiphytic exhibited lots of traits related to water retention, once these plants are not into the ground. Besides, the plasticity observed may contribute for survival of this group in habitats submitted to modifications (e.g., climate change and other variations caused by human interference).

title: Serum nesfatin-1 levels are decreased in pregnant women newly diagnosed with gestational diabetes

description: ABSTRACT Objective To investigate serum nesfatin-1 levels at 24-28 weeks of pregnancy in women newly diagnosed with gestational diabetes and determine the association of nesfatin-1 with several metabolic parameters. Subjects and methods Forty women newly diagnosed with gestational diabetes at 24-28 weeks of pregnancy and 30 healthy pregnant women matched in age and gestational week were included in this cross-sectional study. Serum nesfatin-1 levels were analyzed using ELISA, and the relationship between nesfatin-1 and several metabolic parameters were assessed. Results Serum nesfatin-1 levels were found to be lower in women with gestational diabetes compared to the pregnant women in the control sample (p = 0.020). Multiple linear regression analysis revealed that nesfatin-1 was lower in participants with gestational diabetes independently from gestational age, BMI, HOMA-IR, fasting plasma glucose, and age. In correlation analysis, the only variable that was found to have a statistically significant correlation with nesfatin-1 was gestational age (p = 0.015, r = 0.30). Conclusion Lower nesfatin-1 levels in women with gestational diabetes compared to the control group at 24-28 weeks of gestation draws attention to nesfatin-1 levels in gestational diabetes and motivates further research in this area.
