title: Uni and multivariate approaches for diallel analysis in early generation trials for soybean tolerance to rust

description: ABSTRACT Due to the high impact of Asian soybean rust (SBR) in Brazilian croplands, several studies have been conducted in order to maintain or increase the grain yield gain over years in the presence of the pathogen. The aim of this study was to define a breeding strategy applying uni and multivariate approaches for diallel analyzes in early generation trials and contrasting disease conditions. Thus, assessing genetic parameters to identify traits related to greater tolerance to soybean rust. Deploying a North Carolina design II scheme (4 elite commercial cultivars × 10 rust-tolerant experimental lines), we obtained 40 F2 crosses that were evaluated in a randomized complete block design with 4 replicates. The crosses were conducted in two environments, contrasting only for the fungicide management (with and without rust control), enabling the estimation of the rust impact on 11 traits, divided into two groups: adaptive and reproductive. A multi-environment diallel model was applied assuming all effects as fixed in order to estimate the general (GCA) and the specific (SCA) combining abilities. The multivariate diallel analysis was performed in each rust management using MANOVA to test the genetic effects. The rust conditions were the most important source of variation for almost all evaluated traits. Using the contrasting disease conditions, we were able to identify crosses with desirable SCA and parents with GCA, which implies that tolerance can be used as a strategy to deal with SBR. The implementation and the use of multivariate diallel analysis aiming to increase the efficiency of genotype selection for rust tolerance is discussed.

title: The influence of standardized dry ivy leaf extract on the proportion of nasal secretion after post-septoplasty nasal packing removal,

description: Abstract Introduction: After post-septoplasty nasal packing removal, a certain proportion of nasal secretion occurs, leading to local and sometimes systemic infections. Objective: The aim was to determine if standardized dry ivy leaf extract application after nasal packing removal influences the reduction of nasal secretion and diminish the occurrence of local infections. Methods: The study included 70 post-septoplasty patients (divided into two equal groups) whose nasal packing was removed on the third day after the procedure. Group I was treated with standardized dry ivy leaf extract syrup along with regular nasal irrigation for the five days after the nasal packing removal whereas the Group II had only nasal lavage. On the sixth day after nasal packing removal, the quantity of nasal secretion was determined using a visual analog scale and nasal endoscopic examination. Results: The group treated with standardized dry ivy leaf extract syrup had significantly lesser nasal secretion both by subjective patients’ assessment (p &lt; 0.001) and by nasal endoscopic examination (p = 0.003). The post-surgical follow up examination on the sixth day after nasal packing removal showed no development of local infection in the Group I, while in the Group II a local infection was evident in five patients (14.29%) and antibiotic therapy was required. Conclusion: The use of the standardized dry ivy leaf extract after nasal packing removal significantly lowers the proportion of nasal secretion.

title: Tillering dynamics of Alexandergrass pasture under nitrogen fertilization

description: ABSTRACT This study was carried out to evaluate the effect of nitrogen fertilization on tillering dynamics of Alexandergrass (Urochloa plantaginea (Link) Hitch) grazed by beef heifers in a rotational stocking grazing method. The experiment was conducted in a completely randomized design following a repeated measure arrangement, three levels of nitrogen (Zero, 150 and 300kg ha-1) and two area repetition. The classification of tillers into categories (basal and axillary) showed a greater number of basal tillers, due to their higher appearance rate, in the absence of nitrogen fertilization. Nitrogen fertilization promoted higher axillary tiller density. The use of nitrogen promotes the renewal of axillary tillers of Alexandergrass, without compromising the stability of the tiller population.

title: Caring for the carer: quality of life and burden of female caregivers

description: ABSTRACT Objective: To assess the quality of life and the burden of female caregivers. Method: Descriptive, cross-sectional, quantitative study carried out with 224 informal caregivers from March to July 2016. Three instruments were used: a characterization form for the caregiver, the WHOQOL-Bref questionnaire and the Zarit Burden Interview. The following tests were used: Cronbach’s Alpha, Kolmogorov-Smirnov, Kruskal-Wallis, Spearman and Mann-Whitney. Results: The mean age of caregivers was 51.8 years with a standard deviation of 13.7. They were predominantly married, had a low income and low level of education, were first-degree relatives, had been providing care for one to five years and presented some pathology. The associations of quality of life that presented statistical significance were: income, marital status, number of people living with the caregiver and time of care. Conclusion: The burden was negatively correlated with QOL, that is, the greater the burden, the more impaired will be the life of these caregivers.

title: Preconception health behaviors among women with planned pregnancies

description: ABSTRACT Objective: To identify determinants of preconception preparation among women with planned pregnancies. Method: A cross-sectional study with a probabilistic sample of 264 women between 18 and 49 years of age who had or were undergoing planned pregnancies, and were users of two School Health Centers in the city of São Paulo. Analysis was conducted through univariate and multiple logistic regression of three variable blocks: 1) social and demographic characteristics; 2) sexual and reproductive characteristics; 3) preexisting health conditions. Results: Women with higher education, belonging to economic groups A and B, and older women with infertility were more likely to perform preconception training. Conclusion: Preconception care has a strong social determination, as women with more favorable social profiles are more likely to perform it. Experience with infertility is also instrumental in the likelihood of preconception care.

title: Impact of birth weight and daily weight gain during suckling on the weight gain of weaning piglets

description: ABSTRACT This study evaluated the effect of birth weight and weight gain during the suckling phase on the piglet daily weight gain during the nursery phase (21-61 days of age). Piglets (n= 534) derived from 55 first-parity sows were weighed at birth, weaning, and end of the nursery phase. The data were analyzed according to a completely randomized experimental design, with three classes of birth weight (BW) and two classes of weight gain during the suckling phase (SDWG). High BW and low SDWG piglets were 0.2kg lighter at weaning than low BW and high SDWG animals (P&lt; 0.05). However, at the end of the nursery phase, this situation was inverted, with high BW and low SDWG piglets 2.20kg heavier (P&lt; 0.05). Low BW and high SDWG piglets were heavier at weaning and at the end of the nursery phase than low BW and low SDWG piglets (P&lt; 0.05). At the same time, intermediate and high BW and low and high SDWG piglets presented body weight differences at weaning (P&lt; 0.05), but not at the end of the nursery phase (P&lt; 0.05). Piglets with 1.25 to 2.30kg BW and low weight gain during suckling presented a partial compensatory growth during the nursery phase.

title: Aerodynamic effects on a high slenderness concrete chimney

description: Abstract This paper presents the results of a theoretical-experimental study on the aerodynamic behavior of a 150m high, slenderness 30, concrete chimney. For the wind tunnel tests two scaled models were built: one rigid for the measurement of the external pressures, and other aeroelastic, in which the main dynamic characteristics of the real structure were reproduced. The dynamic response under atmospheric turbulence (along-wind direction) is described in the paper and is compatible with the methodology of the Brazilian wind code NBR-6123. A brief analysis of the transversal response due to vortex shedding is presented according to the Canadian Wind Code NBCC. It is observed that, due to the low frequency of the structure, the dynamic approach leads to results significantly larger than those obtained from applying the conventional static approach of gust wind speed. The presence of the neighborhood have increased the loads on the structures.

title: Drought stress mitigation with humic acid in two Cucumis melo L. genotypes differ in their drought tolerance

description: ABSTRACT Different responses of two melon (Cucumis melo L.) genotypes (Şemame, drought and salt-tolerant and Ananas, drought and salt-sensitive) to drought stress with or without humic acid (HA) treatment were studied. The experiment was carried out under greenhouse conditions. The experimental design was two factorial randomized block with 4 replicates. HA treatment increased the shoot fresh and dry weights and leaf area of both genotypes under drought stress. HA stimulated accumulation of K and Ca ions, chlorophyll (SPAD value) and antioxidant enzyme activity (superoxide dismutase-SOD, catalase-CAT and glutathione reductase-GR) in both genotypes. This effect was more clear in the Şemame genotype than in Ananas.As a result, HA treatment has been proved to influence the ability of melon genotypes to cope with drought stress and to increase their tolerance.

title: Physiological and toxic effects of selenium on seed germination of cowpea seedlings

description: ABSTRACT Selenium (Se) is considered a beneficial chemical element for plants, but in high concentrations it may present symptoms of toxicity. The present study aimed to evaluate 11 concentrations of Se (0; 0.1; 0.5; 1; 5; 10; 20; 40; 80; 400; 800 mg.L-1) to determine the low and high (toxicity) critical levels to seed germination of cowpea (Vigna unguiculata). In addition, alterations in the rate of photosynthetic pigments, lipid peroxidation and sugars during the initial growth development of seedlings were analysed. Seeds exposed to 800 mg.L-1 of Se showed a decrease of 20% of seed germination index compared to the control treatment. The decrease in seedling growth reflected in the increase of total sugars and sucrose concentration in both the shoot and root in response to exposure to Se concentration. There was a decrease in the concentration of leaf chlorophyll, carotenoids and pheophytin from seedlings exposed to high Se concentration. The rate of lipid peroxidation and the hydrogen peroxide concentration in the shoot was reduced up to the concentration of 1 mg.L-1 with subsequent increase in response to Se concentration applied. In the roots, the lipid peroxidation rate increased at concentrations higher than 80 mg.L-1. The highest oxidation rate of the cellular lipid membrane in response to Se occurred in the shoot, due to oxidation reactions in the chloroplast. Degradation of photosynthetic pigments and accumulation of total sugars and sucrose can be considered efficient biomarkers to indicate the toxicity of Se in cowpea seedlings and probably in other crops.

title: AIDS trend in the group of 50-year-old people and more in the previous and subsequent period to the introduction of medicines for erectile dysfunction: Brazil, 1990 to 2003

description: Abstract Objective Describe the behavior of the incidence of Aids in the group of 50-year-old people and more, in Brazil and its macro-regions, from 1990 to 2003, analyzing the previous and subsequent moment of introduction of medicines for erectile dysfunction in the country, in 1998. Methods An ecological study was carried out, along with a space-time analysis of the notified cases of Aids in this group of people. Models of linear regression, adjusted to the time series of Aids cases whose diagnoses date from 1990 to 1997, provided the taxes of annual average variation, as well as the expected values, so making it possible to compare incidence taxes observed and estimated from 1998 to 2003. Results 25,223 cases of Aids in the group of 50-year-old people and more had been analyzed, being the majority (84%) in the Southeast and South regions. Those regions also presented the greatest taxes of annual average variation to the year of 1997 (1.002 and 0.906, respectively), followed by the Middle-West (0.570), North (0.441) and Northeast (0.254); Brazil showed a tax of 0.588. After 1998, the comparison of the taxes accumulated from 1998 to 2003 revealed the expected higher trends than the ones observed in all regions, except for the Northeast. Conclusion The trend of growth of Aids in the 50-year-old people and more group presented greater taxes of growth from 1990 to 1997, and this growth remained in the period subsequent to the introduction of medicines for erectile dysfunction, but more slowly.
