title: Transmission of Colletotrichum truncatum and Macrophomina phaseolina by lima bean seeds

description: ABSTRACT The fungi Colletotrichum truncatum and Macrophomina phaseolina are among the main pathogens associated with lima bean seeds in Brazil, and they are the causal agents of anthracnose and charcoal rot, respectively. The aim of this study was to verify the seed-seedling transmission of C. truncatum and M. phaseolina in artificially inoculated lima bean seeds. Potato-dextrose-agar (PDA) media with different hydric potentials were obtained after the addition of mannitol. Isolates of C. truncatum and M. phaseolina were peaked to these media. Forty grams of seeds were distributed over the fungal mycelium, remaining there for different exposure periods, as a function of each treatment: T1: 0.0 MPa without inoculum for 48 h; T2: 0.0 MPa for 48 h; T3: -0.2 MPa for 48 h; T4: -0.4 MPa for 48 h; T5: -0.6 MPa for 72 h; T6: -0.8 MPa for 96 h and T7: -1.0 MPa for 120 h. The seeds were incubated at 25 ºC under a 12-hour photoperiod. Germination in a paper roll, emergence of seedlings in sand and seed health in PDA were evaluated. T4 provided the best conditions to temporarily prevent seed germination, promoting a greater incidence of seeds infected by C. truncatum and a greater percentage of diseased plants. M. phaseolina reduced seed germination, independently of the inoculated treatment. Both fungi were transmitted from the seeds to the seedlings of lima bean, causing symptoms in various aerial parts. C. truncatum and M. phaseolina transmission rate was 83.1% and 76.46%, respectively.

title: APPLICATION OF UNCERTAINTY ANALYSIS OF ARTIFICIAL NEURAL NETWORKSFOR PREDICTING COAGULANT AND ALKALIZER DOSAGES IN A WATER TREATMENT PROCESS

description: ABSTRACT Artificial neural networks (ANNs) were built to predict coagulant (Model I) and alkalizer (Model II) dosages given raw and treated water parameters from a water clarifying process. Different ANN architectures were tested and optimal results were obtained with [10-10-10-01] and [08-12-12-01] nodes of input, hidden and output layers for Models I and II, respectively. Two algorithms based on GUM-S1weredevelopedto evaluate the artificial neural network parameter uncertainty and the coverage interval of model outputs. The results show that these algorithms can provide a better set of parameters for the ANN compared with the traditional training method. The present research provides a unique unifying view that considers neural networks and uncertainty analysis in a well-documented industrial case study.

title: Biochemical and epidemiological components associated with rice resistance to brown spot

description: ABSTRACT Brown spot (Bipolaris oryzae) is one of the most important leaf diseases affecting rice. To epidemiologically and biochemically understand the variation in resistance among rice genotypes, in this study some resistance components and some biochemical variables, widely known as plant defense mechanisms against pathogens, were evaluated in rice genotypes classified, according to SOSBAI, as moderately susceptible, moderately resistant and resistant. Seven rice cultivars were inoculated with 1 × 104 conidia mL-1 of B. oryzae and the following resistance components were evaluated: relative infection efficiency (ERI); final lesion number (NFL); final lesion length (CFL); lesion growth rate (r) and final severity (SF). In addition, biochemical variables such as activity of the enzymes superoxide dismutase (SOD), catalase (CAT), peroxidase (POX), chitinase (CHI) and phenylalanine ammonia-lyase (PAL) were analyzed. Results showed significant differences among cultivars for resistance components, as well as for enzyme activities. All tested genotypes were susceptible to B. oryzae, varying for the level of partial resistance to brown spot. The variables r and CFL showed higher correlation to SF, indicating to be the variables that most influenced the final disease intensity in each genotype. Rice genotypes showing higher partial resistance to brown spot had alterations characterized as earlier, potentiated and longer SOD, CAT POX and PAL activities.

title: Adequate versus inadequate weight gain and socioeconomic factors of pregnant women followed up in primary care

description: Abstract Objectives: to identify the socioeconomic factors associated with inadequate (excessive and insufficient) weight gain in women followed during prenatal care in Basic Health Units in a Municipality of the Countryside of Ceará. Methods: a study was carried out with 189 pregnant women. Data were tabulated in the Excel Program and data analysis was performed in the Stata Program. In the bivariate analysis, the chisquare or Fisher's exact test was used, and the Poisson multivariate regression was used for the association between variables and the excessive or insufficient weight gain. Results: insufficient weight gain was associated with the absence of the partner (RR=1.15 CI95% = 1.02 - 1.30) and excessive weight gain was associated with non-working women (RR = 0.90 CI95% = 0.84-0.96). Conclusions: absence of partner and lack of work were associated with inadequate weight gain during pregnancy.

title: STUDY OF THE REDUCTION PROCESS OF IRON IN LEACHATE FROM NICKEL MINING WASTE

description: ABSTRACT A mechanism to convert Fe(III) to Fe(II) by a reduction process could be a solution to the problem of selective separation of metals in extraction processes by using the ion-exchange process. The aim of this research was to reduce Fe(III) to Fe(II) present in leachate from nickel mining waste. Reducing agents used were sodium dithionite and sodium metabisulfite. The potential was decreased in order to quantify the minimum reducing agent that was necessary for conversion. Reaction time, pH, stirring speed and temperature were also studied. Results indicated dithionite was a better reducing agent than metabisulfite and complete conversion was possible by reducing the potential to 590mV at pH 0.5-2 and 240mV at pH 2.5. Stirring speed had no influence on the reduction process at 2 hours; however, conversion decreased after 24 hours, perhaps due to oxygen present in air. The analyses were conducted by ion chromatography and voltammetry.

title: The Living Will: Knowledge and Attitudes of Medical Interns

description: ABSTRACT Introduction The living will is a document in which the patient defines what kind of medical procedures he or she wishes to undergo during the final stage of life, and is an important tool for guaranteeing the patient’s dignity and autonomy. Objective To evaluate the level of understanding among medical interns about the living will and end-of-life decisions. Methods This was a quantitative, descriptive, cross-sectional study conducted with 147 medical students taking their internship, through a questionnaire composed of 10 questions. These questions enabled us to evaluate the students’ level of knowledge about the living will, and to verify their personal opinions on how far the content of this document should be respected, and to ask whether they had had an opportunity to discuss the living will during their undergraduate studies. The students’ knowledge of the living will was categorized into three groups: “clear understanding”, “partial notion,” and “misconception or misunderstanding of the term.” Results Among the interns interviewed, only 12.9% had a clear understanding of the meaning of the term “living will”, while 74.2% had a partial notion of the term and 12.2% had a misconception of the term. Nonetheless, 96.6% of the students reported that this topic was discussed during their graduate studies, and 87.1% reported knowledge of Federal Medical Council Resolution no. 1995 of 2012. Most of the students (98%) stated that in the case of a terminally ill patient with a living will, they would comply with the provisions of this document. Conclusion Although many of the students had some knowledge of the term “living will”, only a small portion of them had a clear understanding of its meaning. Despite this, their attitudes towards a patient with a living will were clearly positive, demonstrating good acceptance of the living will among future physicians.

title: Performance of Nellore calves in tropical pasture consuming different types of concentrated supplements

description: ABSTRACT The use of different types of concentrated supplements on the performance of Nellore calves grazing Urochloa brizantha cv. Marandu in the dry season was evaluated. The experiment was conducted on 24 ha divided into 12 paddocks. Seventy-two calves with initial body weight (BW) 176±14kg for 140 days of experiment were used. Evaluated treatments included: Mineral, Salt+urea (mineral with 30% urea), Protein (supplementation with 45% crude protein (CP) and 46% total digestible nutrients (TDN)); and Protein+energy (with 28% CP and 73% TDN). The Mineral, Salt+urea, and Protein were offered ad libitum, and the Protein+energy 5g/kg BW. Protein+energy showed the highest (P&lt; 0.05) intake (3.66g/kg BW) followed by the Protein (1.61), Salt+urea (0.36), and Mineral (0.32). The two latter supplements were not significantly different (P&gt; 0.05). The highest (P&lt; 0.05) average daily gain (ADG, kg/day) was observed in the Protein+energy (0.074). Average daily gains for the Protein and Salt+urea (0.014 and -0.024, respectively) were not significantly different (P&gt; 0.05), but were significantly higher (P&lt; 0.05) than the Mineral (-0.085). Therefore, during the dry season, to prevent the loss of bovine weight the supplements must supply in addition to minerals, also energy, non-protein nitrogen (NNP), and true protein.

title: Activation of locus coeruleus heme oxygenase-carbon monoxide pathway promoted an anxiolytic-like effect in rats

description: The heme oxygenase-carbon monoxide pathway has been shown to play an important role in many physiological processes and is capable of altering nociception modulation in the nervous system by stimulating soluble guanylate cyclase (sGC). In the central nervous system, the locus coeruleus (LC) is known to be a region that expresses the heme oxygenase enzyme (HO), which catalyzes the metabolism of heme to carbon monoxide (CO). Additionally, several lines of evidence have suggested that the LC can be involved in the modulation of emotional states such as fear and anxiety. The purpose of this investigation was to evaluate the activation of the heme oxygenase-carbon monoxide pathway in the LC in the modulation of anxiety by using the elevated plus maze test (EPM) and light-dark box test (LDB) in rats. Experiments were performed on adult male Wistar rats weighing 250-300 g (n=182). The results showed that the intra-LC microinjection of heme-lysinate (600 nmol), a substrate for the enzyme HO, increased the number of entries into the open arms and the percentage of time spent in open arms in the elevated plus maze test, indicating a decrease in anxiety. Additionally, in the LDB test, intra-LC administration of heme-lysinate promoted an increase on time spent in the light compartment of the box. The intracerebroventricular microinjection of guanylate cyclase, an sGC inhibitor followed by the intra-LC microinjection of the heme-lysinate blocked the anxiolytic-like reaction on the EPM test and LDB test. It can therefore be concluded that CO in the LC produced by the HO pathway and acting via cGMP plays an anxiolytic-like role in the LC of rats.
