title: CONCENTRATION EFFECT OF THE EU3+ AND BI3+ IN THE PHOTOLUMINESCENCE PROPERTIES OF YVO4 MATRIX

description: Inorganic matrices have been extensively studied for several applications, mainly doped with lanthanoid ions presenting special spectroscopic properties. The radiation emission can be affected by several factors, such as; matrix, synthesis methodology, activating ions and sensitizers, and concentrations. Thus, in this work the matrix of yttrium vanadate doped with Eu3+ ions as activator and Bi3+ ions as sensitizer was prepared by the non-hydrolytic sol-gel methodology. Europium (III) and Bismuth (III) ions concentrations were varied in 1, 3 and 5% in mol with respect to the Y3+ ion and the samples were heat treated at 1000 °C. The X-ray diffraction analyzes showed a single phase of the yttrium vanadate matrix, indicating the non-influence of the dopant ions on the crystalline structure. The dopants concentrations presented influences on the spectroscopic properties of the emitting ion, the intensity parameters (Ω2 e Ω4), increased as a function of the increase of Bi3+ concentration, affecting the covalence of the bond and the rigidity of the system. The increase of Eu3+ concentration directly affected its environment, decreasing the symmetry and increasing the quantum efficiency. Finally, increasing the dopant ions promoted the decreasing the crystallite size.

title: Duckweed in Irrigation Water as a Replacement of Soybean Meal in the Laying Hens’ Diet

description: ABSTRACT Water lentils (Duckweed [DW])(Lemna gibba), in irrigation ponds, was evaluated by replacing two levels of soybean meal (SBM) on performance and egg quality of laying hens of 54 weeks of age. A total of 72 white Lohmann laying hens were randomly allocated into 3 treatments with 6 replicates/treatment, 4 hens/replicate in a randomized complete block design. Treatments were: control group (DW0%) with (SBM) as the main source of protein, T1 (DW10%) and T2 (DW20%), where duckweed replaced 10% and 20% of SBM for 9 weeks. No significant differences were observed among the dietary treatments in body weight change, feed conversion ratio, egg weight and mortality rate. Replacement with (DW20%) decreased (p&lt;0.05) feed intake, egg laying rate and egg mass. The dry albuminin (DW10%) decreased (p&lt;0.05) from 7 to 9 weeks and in the total period. Yolk pigmentation was highly (p&lt;0.001) improved by the replacement. Blood spots were increased (p&lt;0.05) with (DW20%). Duckweed grown in good quality irrigation water can replace up to 10% of the SBM as a source of protein without adverse effects on hen performance and egg quality in addition to profitability.

title: Phenotypic and molecular detection of metallo-β-lactamase-producing Pseudomonas aeruginosa isolates from patients with burns in Tehran, Iran

description: Abstract INTRODUCTION: Health care-associated infections caused by metallo-β-lactamase (MBL)-producing Pseudomonas aeruginosa are a significant growing concern in patients with burns worldwide. The aims of this study were to determine the antibiotic susceptibility of and detect the presence of MBLs among P. aeruginosa isolates and assess their clonal relationship using enterobacterial repetitive intergenic consensus (ERIC)-PCR. METHODS: Non-duplicated clinical isolates (160) of P. aeruginosa were collected from patients with burns at the Motahari Hospital in Tehran, Iran. All isolates were identified using standard laboratory methods and further characterized for antimicrobial susceptibility. Any carbapenem-resistant isolates were then examined for MBL production by the E-test and MBL-encoding genes were detected by PCR. The clonal relatedness of MBL-producing isolates was assessed by ERIC-PCR. RESULTS: For multidrug-resistant isolates, the highest rates of susceptibility were observed for colistin 160 (100%), polymyxin B 160 (100%), and ceftazidime 32 (20%). In total, 69 (43.7%) isolates were identified as MBL producers. Twenty-eight (17.5%) isolates were positive for the bla VIM-1 gene followed by the bla IMP-1 (15.6%) and bla SPM-1 (5.6%) genes. ERIC-PCR revealed three separate genotypes, where type A (76.8%) was the most prevalent, followed by B (20.3%), and then C (2.9%). CONCLUSIONS: Our present study found that the bla IMP-1 and bla VIM-1 genes were present at a significant frequency and also detected the bla SPM-1 gene in P. aeruginosa isolates for the first time, highlighting the need for establishing suitable infection control measures to successfully treat patients and prevent further spread of these resistant organisms among patients with burns.

title: Occurrence, pathogens and risk factors for subclinical mastitis in dairy goats

description: ABSTRACT Milk samples from 257 goats and 513 half udders of 10 dairy goat farms were analyzed by microbiological culture, to evaluate the sanitary management, and epidemiological questionnaire results. Multivariate analysis of risk factors for subclinical mastitis in goats, with the adjusted Odds Ratio for subclinical mastitis was performed. The prevalence of subclinical mastitis in goats by microbiological culture was 43.6%, and clinical mastitis was 5.84%. From 178 positive teats by microbiological culture, the most prevalent pathogens were coagulase-negative staphylococci - CNS (70%), S. aureus (13.5%), S. intermedius (7.9%), and Enterobacteriaceae (4%). The risk factors analysis revealed significant association between the disease and the flock size (OR= 3.33; P= 0.0268), and the farm was a confounding factor, being kept in the final statistical model. Despite the non-identification of all the factors associated with subclinical mastitis in herds and the existence of confounding factors that hinder statistical analyzes, the study of risk factors is important for the improvement of disease control and prevention programs in dairy goat, and it can be used as a tool in the reduction of environmental and contagious pathogens such as staphylococci that were the most identified pathogens causing caprine mastitis in the study.

title: Evaluation of clinical trials in Brazil: history and current events

description: Abstract Clinical trials must be approved and monitored by ethical and regulatory authorities to ensure that the ethical conduct and technical aspects of the research are in compliance with required standards. The in-depth understanding of this process is crucial for studies to be delineated and conducted in accordance with applicable standards, being an essential part of national technical and scientific training. The evaluation of the studies in Brazil is performed by the research ethics committees, by the National Research Ethics Commission and by the Brazilian regulatory agency, the Agência Nacional de Vigilância Sanitária (National Health Surveillance Agency). Researchers and sponsors claim that the time taken for approval and initiation of clinical trials limits further studies. However, Brazilian standards are constantly improving, demonstrating the interest and ability to improve procedures, without losing quality in ethical evaluation.

title: LIQUID-LIQUID EQUILIBRIA FOR SYSTEMS CONTAINING FATTY ACID ETHYL ESTERS, ETHANOL AND GLYCEROL AT 333.15 AND 343.15 K: EXPERIMENTAL DATA, THERMODYNAMIC AND ARTIFICIAL NEURAL NETWORK MODELING

description: Abstract In this study, the liquid-liquid equilibrium (LLE) data of systems containing ethyl linoleate/oleate/palmitate/laurate, ethanol and glycerol at temperatures ranging from 323.15 to 353.15 K were used to evaluate the performance of the NRTL, UNIFAC, Cubic-Plus-Association Equation of State (CPA EoS), and artificial neural network (ANN) models. The systems evaluated correspond to the most important components formed at the end of the ethanolysis reaction of soybean, palm and coconut oils. The temperature range selected is very important for heterogeneous catalysts, especially for high-pressure systems. The accuracy of the models was evaluated by average global deviation. UNIFAC, UNIFAC-LLE and CPA EoS models showed lower accuracy with deviations of 10.1, 8.01 and 5.95%, respectively. In spite of this predictive limitation, these models show high extrapolation capability for the description of LLE behavior when few experimental data are available in the literature. The ANN model shows the best agreement between experimental and predicted data with an average deviation of 1.12%. In this regard, ANN is offered in this work as an alternative to equations of state and activity coefficient models to be used in a more reliable and less cumbersome way for process simulators of biodiesel production and separation equipment design.

title: Coping strategies among caregivers of people with Alzheimer disease: a systematic review

description: Abstract Introduction Caregivers of people with Alzheimer disease (PwAD) report significant stress, burden and depression compared to caregivers of people with other dementias, especially when neuropsychiatric symptoms are prominent. Adequate coping strategies can modify the impact of stressful situations and increase the caregivers’ quality of life. Objective To systematically review the different coping strategies used by caregivers of PwAD to manage neuropsychiatric symptoms. Method We carried out electronic searches using MEDLINE (PubMed), SciELO, Web of Knowledge Cross Search (Thomson Scientific/ISI Web Services) and PsycINFO databases to select studies on coping in PwAD caregivers published from January 2005 to July 2017. The search terms were coping, caregivers, strategy, onset, adaptation, family, behavior, dementia and Alzheimer. The studies were organized in three categories: problem-focused, emotion-focused and dysfunctional coping strategies. Results We found 2,277 articles. After application of exclusion criteria and exclusion of redundant references, 24 articles were analyzed. Emotion-focused coping was the most commonly used strategy among PwAD caregivers. The use of this strategy associated with religion and spirituality may help reduce symptoms of depression and anxiety. Problem-focused coping strategies were mostly used with active coping interventions. Problem-solving coping may have buffered the impact of acute psychological stressors on procoagulant activity. Dysfunctional coping strategies were associated with increase of caregiver burden. Conclusion The evaluated studies showed that the use and development of coping strategies may have ameliorated the depressive symptoms, anxiety and burden of caregivers. However, longitudinal studies are still needed that clearly describe the type of coping strategy used in relation to the presented results.

title: First record of Ornithodoros faccinii (Acari: Argasidae) on toads of genus Rhinella (Anura: Bufonidae) in Brazil

description: Abstract Although a group of soft ticks (Argasidae) associated with amphibians was recently discovered in Brazilian rainforests, parasitism by these ticks on cold-blooded animals remains less common than on mammal and bird species. In this study, we identified ticks that were collected from toads that had been caught in December 2016 and January 2017, at Itinguçú waterfall (22°54’05” S; 43°53’30” W) in the municipality of Itaguaí, state of Rio de Janeiro. Tick specimens were identified using a morphological and molecular approach. In total, twelve larvae of Ornithodoros ticks were collected from three individuals of Rhinella ornata and were identified as Ornithodoros faccinii. Our results include a longer 16S rRNA mitochondrial sequence for O. faccinii that supports its phylogenetic relatedness to Ornithodoros saraivai, and we report this tick species parasitizing Rhinella toads for the first time in Brazil.
