title: Correlations between agronomic traits and path analysis for silage production in maize hybrids

description: ABSTRACT The aim of the current study is to estimate the correlation coefficients and the consequence of genotypic correlations on direct and indirect effects through path analysis between agronomic traits of maize hybrids used for silage production. Eight (8) topcross hybrids and seven (7) checks were analyzed in completely randomized blocks, with six replications, in two environments: Campos do Goytacazes and Itaocara counties – Rio de Janeiro State, in the crop year 2015/2016. The following agronomic traits were assessed: plant height, first ear height, culm diameter, number of ears, ear yield with straw at silage maturity, ear yield without straw at silage maturity, grain yield at silage maturity, grains ratio in the fresh matter and fresh matter yield. The highest correlation estimates were found between the variables ear yield without straw and grain yield, and between ear yield with straw and ear yield without straw, with magnitudes 0.95 and 0.92, respectively. The coefficient of determination was high, which indicates that the assessed components explain most of the existing variation in fresh matter yield. According to the path analysis, the trait showing the strongest direct effect on fresh matter yield was the ear yield with straw at silage maturity, in association with the high correlation (r = 0.91), which showed the possibility of achieving significant gains through indirect selection.

title: Plot size related to numbers of treatments and replications, and experimental precision in dwarf pigeon pea

description: ABSTRACT The aim of this study was to determine the optimum plot size to evaluate the fresh matter of aerial part of dwarf pigeon pea (Cajanus cajan (L.) Millsp), cultivar IAPAR 43 (Aratã), in scenarios formed by combinations of numbers of treatments, number of replications, and precision levels. The fresh matter of aerial part was weighed on basic experimental units of 1 m × 1 m in three uniformity trials with size of 24 m × 12 m (288 m2 in each trial). The soil heterogeneity index of Smith was estimated. Also, the optimum plot size was determined by Hatheway’s method in scenarios formed by combinations of i treatments (i = 5, 10, 15, and 20), r replications (r = 3, 4, 5, 6, 7 8, 9, and 10), and d precision levels (d = 5%, 10%, 15%, 20%, 25%, and 30%). In experiments designed on randomized block design with 5 to 20 treatments and four replications, plots with 9 m2 were enough to identify significant differences among treatments regarding the fresh matter of aerial part in dwarf pigeon pea at 5% probability of 30% of the experiment overall mean.

title: An atypical Lettuce mosaic virus isolate breaking mo12 gene in lettuce

description: ABSTRACT Lettuce (Lactuca sativa L.) belongs to the Asteraceae family and is one of the most consumed vegetables in Brazil. Lettuce mosaic virus (LMV) an important virus for this crop and, currently, its main control form is based on the utilization of genotypes carrying the tolerance gene mol1 and mol2. A LMV isolate from Botucatu (SP), named LMV-Bot, was identified considering its biological and molecular characteristics. When inoculated in distinctive lettuce varieties that classifies LMV pathotypes (‘Ithaca - Mo gene’, ‘Malika – mol1’ ‘Vanguard 75 - Mo and mol2’ and ‘Salinas 88 - mo12’), LMV-Bot induced symptoms only in ‘Salinas 88’. The N’ terminal coding region for the capsid protein was amplified and sequenced, and its phylogenetic position revealed similarity to two Brazilian isolates named BR6 and A435 and to another one from France (FR4). However, LMV-Bot did not fit in the sub-group Most and Common. Results suggest that, although rare, atypical isolates of LMV are found in nature infecting lettuce and can break the resistance gene mol2.

title: ISOSTERIC HEAT, ENTROPY, AND GIBBS FREE ENERGY OF PUMPKIN SEEDS (Cucurbita moschata)

description: ABSTRACT To maintain seed and soil quality of pumpkin, energy knowledge associated with processing and storage stages is strategic for the optimization of the thermodynamic processes needed for product stabilization. Thus, the objective of this study was to determine isosteric heat, differential entropy, and Gibbs free energy within a temperature range from 20 to 70° C, and relative air humidity levels between 10.75 and 85.11%. The study was based on empirical data for water activity determination. As a result, we verified that as moisture content decreased, the integral isosteric heat of the product increased from 2502.35 to 6231.17 kJ kg-1, differential entropy raised from 1.18 to 12.43 kJ kg-1 K-1, and Gibbs free energy ranged from -243.84 to -432.59 kJ kg-1. Thus, we concluded that the lower the water availability in seeds, the greater the energetic requirement for its removal, as there is a major interaction between water and the product (seeds), indicating an increasingly less spontaneous desorption process.

title: The role of surgery in primary central nervous system lymphomas

description: ABSTRACT Background Primary central nervous system lymphomas (PCNSL) are infrequent. The traditional treatment of choice is chemotherapy. Complete resections have generally not been recommended, because of the risk of permanent central nervous system deficits with no proven improvement in survival. The aim of the current study was to compare survival among patients with PCNSL who underwent biopsy versus surgical resection. Methods A retrospective study was conducted on 50 patients with a confirmed diagnosis of PCNSL treated at our center from January 1994 to July 2015. Results Patients in the resection group exhibited significantly longer median survival time, relative to the biopsy group, surviving a median 31 months versus 14.5 months; p = 0.016. Conclusions In our series, patients who had surgical resection of their tumor survived a median 16.5 months longer than patients who underwent biopsy alone.

title: Integrating the pastoral component in agricultural systems

description: ABSTRACT This paper aims to discuss the impact of the introduction of pastures and grazing animals in agricultural systems. For the purposes of this manuscript, we focus on within-farm integrated crop-livestock systems (ICLS), typical of Southern Brazil. These ICLS are designed to create and enhance the synergisms and emergent properties have arisen from agricultural areas where livestock activities are integrated with crops. We show that the introduction of the crop component will affect less the preceding condition than the introduction of the livestock component. While the introduction of crops in pastoral systems represents increasing diversity of the plant component, the introduction of animals would represent the entry of new flows and interactions within the system. Thus, given the new complexity levels achieved from the introduction of grazing, the probability of arising emergent properties is theoretically much higher. However, grazing management is vital in determining the success or failure of such initiative. The grazing intensity practiced during the pasture phase would affect the canopy structure and the forage availability to animals. In adequate and moderate grazing intensities, it is possible to affirm that livestock combined with crops (ICLS) has a potential positive impact. As important as the improvements that grazing animals can generate to the soil-plant components, the economic resilience remarkably increases when pasture rotations are introduced compared with purely agriculture systems, particularly in climate-risk situations. Thus, the integration of the pastoral component can enhance the sustainable intensification of food production, but it modifies simple, pure agricultural systems into more complex and knowledge-demanding production systems.

title: Essential oils and thermal treatment in the postharvest control of green mold in orange

description: ABSTRACT Green mold is the primary postharvest disease of citrus fruits. Alternative products and processes for plant disease control have been increasingly required. The aim of this study was to evaluate the antifungal activity of essential oils on P. digitatum in oranges, alone or in combination with thermal treatment. Thus, an isolate of the fungus was subjected, in vitro, to different concentrations of oils of cinnamon, lemongrass and palmarose, in PDA culture medium; the antifungal activity of the volatile compounds of oils was also evaluated. Furthermore, a study was conducted to verify the effect of oils on inoculated oranges, in a protective and curative mode. Oranges were inoculated with 10 uL conidial suspension (105 conidia mL-1), two incubation periods (4 h before or 24 h after treatments). The treatments with essential oils that were sprayed were: control, cinnamon, lemongrass and palmarose, at 0.5 and 1.0 g L-1, plus Tween20. Another test with cinnamon oil, to determine the best dose, was conducted by using 0.0; 0.12; 0.25; 0.5 and 1.0 g L-1 and a blend of cinnamon (0.12 g L-1) and lemongrass (0.12 g L-1). Storage was at 25 °C and 80% relative humidity (RH) for up to 6 days. Subsequently, a test was conducted in oranges inoculated 4 h before treatments: control; cinamon (0.12 g L-1); thermotherapy (60 °C for 20 s); thermotherapy + cinnamon oil; and imazalil (1000 mg L-1). The fruits were stored at 10 °C/85% RH for 6 days plus 3 days at room conditions. In vitro, cinnamon oil was most fungitoxic for P. digitatum, totally inhibiting the mycelial growth index at concentrations higher than 0.5 g L-1 by contact and significantly reducing it by its volatile compounds. For inoculated oranges, cinnamon oil was more effective as curative and lemon grass as protective. In the screening test, the dose of 0.12 g L-1 cinnamon oil showed better result compared to higher doses and to the blend of cinnamon and lemon grass. The thermotherapy combination followed by spraying of cinnamon oil significantly reduced green mold development (AACPD) in fruits (40.5%) stored under refrigeration; however, the fungicide imazalil provided a more effective control (97%) during prolonged storage.

title: Is phrenic nerve conduction affected in patients with difficult-to-treat asthma?

description: ABSTRACT Objective The aim of this study was to obtain data on phrenic neuroconduction and electromyography of the diaphragm muscle in difficult-to-treat asthmatic patients and compare the results to those obtained in controls. Methods The study consisted of 20 difficult-to-treat asthmatic patients compared with 27 controls. Spirometry, maximal inspiratory and expiratory pressure, chest X-ray, phrenic neuroconduction and diaphragm electromyography data were obtained. Results The phrenic compound motor action potential area was reduced, compared with controls, and all the patients had normal diaphragm electromyography. Conclusion It is possible that a reduced phrenic compound motor action potential area, without electromyography abnormalities, could be related to diaphragm muscle fiber abnormalities due to overload activity.

title: Peptidomic investigation of Neoponera villosa venom by high-resolution mass spectrometry: seasonal and nesting habitat variations

description: Abstract Background: Advancements in proteomics, including the technological improvement in instrumentation, have turned mass spectrometry into an indispensable tool in the study of venoms and toxins. In addition, the advance of nanoscale liquid chromatography coupled to nanoelectrospray mass spectrometry allows, due to its high sensitivity, the study of venoms from species previously left aside, such as ants. Ant venoms are a complex mixture of compounds used for defense, predation or communication purposes. The venom from Neoponera ants, a genus restricted to Neotropical regions, is known to have cytolytic, hemolytic, antimicrobial and insecticidal activities. Moreover, venoms from several Neoponera species have been compared and differences in their toxicity related to nesting habitat variation were reported. Therefore, the present study aimed to perform a deep peptidomic analysis of Neoponera villosa venom and a comparison of seasonal and nesting habitat variations using high-resolution mass spectrometry. Methods: Specimens of N. villosa ants were captured in Panga Natural Reserve (Uberlândia, MG, Brazil) from arboreal and ground-dwelling nests during summer and winter time. The venom glands were dissected, pooled and disrupted by ultra-sonic waves. The venom collected from different habitats (arboreal and ground-dwelling) and different seasons (summer and winter) was injected into a nanoACQUITY ULPC hyphened to a Q-Exactive Orbitrap mass spectrometer. The raw data were analyzed using PEAKS 7. Results: The results showed a molecular diversity of more than 500 peptides among these venoms, mostly in the mass range of 800–4000 Da. Mutations and post-translational modifications were described and differences among the venoms were observed. Part of the peptides matched with ponericins, a well-known antimicrobial peptide family. In addition, smaller fragments related to ponericins were also identified, suggesting that this class of antimicrobial peptide might undergo enzymatic cleavages. Conclusion: There are substantial differences among the venom of N. villosa ants collected in different seasons and from different nest habitats. The venom composition is affected by climate changes that influence prey availability and predator presence. Clearly, nano-LC-MS boosted the knowledge about ant venom, a rich source of unexplored and promising bioactive compounds.
