title: Quality monitoring of soybean seed tests using Statistical Process Control

description: ABSTRACT The success of soybean cultivation depends on several factors, one which is the use of high-quality seeds, which can guarantee growth of the desired plant population. The objective of this study was to monitor possible failures during the seed production process, and to determine the association between germination and tetrazolium tests through tools of Statistical Process Control (CEP). The experimental design was based on premises of the CEP, using percentage of germination, seed viability, mechanical damage, bed bug, and moisture as indicators of quality. It is possible to detect flaws in the soybean production process through control charts, as well as through germination and tetrazolium tests; results indicated that germination failures are largely caused by mechanical damage and bed bug attacks.

title: Vertebral Osteomyelitis in Broilers: A Review

description: ABSTRACT Locomotor diseases are still a challenge in modern poultry. Vertebral osteomyelitis (VO) is an emerging disease in broilers worldwide. The inflammatory process in the affected thoracic vertebra (T4) and subsequent spinal cord compression leads to clinical signs related to locomotor impairment, inadequate feeding and drinking, and increased mortality in the affected flocks. The pathogenesis of the disease is poorly understood and Enterococcus cecorum is the bacterium most frequently associated with the disease. However, other bacteria such as E. faecalis, E. durans, Escherichia coli and Staphylococcus aureus have been recently detected in cases of the disease, raising questions regarding its etiopathogenesis. As many questions about VO in broilers remain unanswered, knowledge on its prevention, control and treatment is limited. In this review, we compile and discuss the currently available information concerning VO in broilers and highlight important aspects of the disease.

title: Optimized conditions to produce water-in-oil-in-water nanoemulsion and spray-dried nanocapsule of red ginseng extract

description: Abstract The aim of this study was to optimize conditions for producing water-in-oil-in-water (W/O/W) nanoemulsion and spray-dried nanocapsule of red ginseng extract. Based on emulsion stability and average particle size analysis, optimum conditions to produce W/O/W nanoemulsion were: ratio of core to coating material, 3:7; primary emulsifier, 10% polyglycerol polyricinoleate; ratio of W/O phase to coating material, 1.5:8.5; secondary emulsifier, 10% polyoxyethylene sorbitan monolaurate; solvent, 20% ethyl acetate; secondary coating material, 10% maltodextrin (MD). Under these optimized conditions, particle size of spray-dried nanocapsules coated with MD of red ginseng ranged from 100 nm to 500 nm, based on response surface methodology with the highest yield (up to 99.7%). Results of the present study can be used to further optimize conditions to produce W/O/W nanoemulsion and spray-dried nanocapsule of red ginseng extract.

title: Doses of NPK formulations combined with humic substance at sowing in barley cultivars

description: ABSTRACT This study aimed to evaluate NPK formulations used in fertilization at sowing associated with and without humic substances (HS) in terms of the agronomic characteristics and grain quality for malt from the barley cultivars BRS Brau and BRS Elis, focusing on the agricultural years 2015 and 2016 in Guarapuava, PR. The experimental design was a randomized block, in a factorial 5 x 2 format, with five fertilizations: 0 kg ha-1 (control); 100 kg ha-1 of NPK; 100 kg ha-1 NPK + HS; 250 kg ha-1 of NPK; and 250 kg ha-1 NPK + HS, using two barley cultivars, BRS Brau and BRS Elis, replicated four times. The variables evaluated were hectoliter weight, grain yield, malt quality by means of sort 1, 2 and 3, and the protein percentage. The data evaluated were submitted to joint variance analyses for the agricultural crops, and the means were compared through non-orthogonal contrasts. The use of humic substances in NPK formulations provides an increase in grain yield, and its effect is observable in the lower doses of NPK + HS formulations. The lower dose of NPK formulation combined with the humic substance reduced class 1 and increased class 3 in agricultural crops from the years 2015 and 2016. The 2016 crop, with favorable climatic conditions, presented improved hectoliter mass, grain yield and quality of the barley grains, based on commercial grade.

title: Socioeconomic diversities and infant development at 6 to 9 months in a poverty area of São Paulo, Brazil

description: Abstract Introduction The effects of socioeconomic disparities on cognitive development tend to emerge early in infancy and to widen throughout childhood, and may perpetuate later in life. Although the study of how poverty affects early childhood has increased in the last 20 years, many of the effects remain largely unknown, especially during the first year of life. Aim To investigate the influence of socioeconomic status (SES) and maternal education on infants’ language, motor and cognitive development. Methods The cognitive, language and motor skills of 444 infants aged 6 to 9 months selected from a poor neighborhood in São Paulo, Brazil, were evaluated using the Bayley Scales of Infant Development. A questionnaire on socioeconomic background was administered to the participants’ families. Results A positive association was found between SES and infants’ performance on language and motor scales. Additionally, higher maternal education was associated with higher language and cognitive scores. Conclusion Our findings indicate that SES effects are detectable very early in infancy. This result has implications for the timing of both screening and intervention efforts to help children overcome the consequences of living in poverty.

title: Persistence and efficacy of a new formulation based on dog allomonal repellents against Rhipicephalus sanguineus sensu lato tick

description: Abstract Beagles are less susceptible to Rhipicephalus sanguineus sensu lato tick due to the production of the allomones benzaldehyde and 2-hexanone. Our previous published work showed that these compounds can reduce tick burden on susceptible dogs. Here we tested the hypothesis that an increase in repellent dose and release rate could increase repellent efficacy and persistence. Slow-release formulations of these compounds, with higher doses and release rates, were tested on artificially-infested dogs. Ten dogs were randomly assigned to two groups with five dogs each. The treated group received collars with slow-release formulations of the compounds attached, while the control group received collars with clean formulations attached. Five environmental infestations were performed, with the number of ticks (at all stages) on the dogs being counted once a day for 40 days. No significant increase in repellent efficacy was observed with the higher doses and release rates, whereas a greater persistence in repellent activity was observed. Treatment with the formulations resulted in a two-to-three-fold reduction in the number of immature stage ticks for up to three weeks. However, the number of adults was similar in both groups. Loss of repellent activity after the third week of testing coincided with a marked change in the relative release rates for the two compounds. It is hypothesized that relative amounts, rather than absolute amounts, of repellent release from slow-release formulations are important for repellent activity. We also hypothesize that the avoidance of less-preferred hosts by ticks relies on olfactory-mediated perception of specific blends of volatile cues from less preferred hosts.

title: Structural Attributes Dynamics of the Brazilian Broiler Production Chain

description: ABSTRACT Brazil is one of the world’s largest broiler meat exporters. Broiler meat is one of the most consumed meats worldwide. The most significant challenge for strategic business management when optimizing the financial returnis knowing exactly where to invest. The same happens in the broiler production chain. The present research aimed to investigate which were the most central actors in the broiler supply chain and the dynamics of the chain. The current study was done based on the poultry chain business relations, from 2000 to 2015, of the leading actors of the Brazilian broiler production chain. The centrality indicator was established through social network analysis (SNA) approach, to determine their positions in the chain as a whole. The most used indicators within network analysis are those designed to identify the extent to which one actor occupies a more central position than another. The Gephi® software was applied to calculate the structural attributes and indicators of the network. Results were estimated using the RapidMiner® software. A model was presented that shows one infrastructure indicator as an explanatory variable. The findings indicate that the centrality indicator was weakly influenced when compared to the other variables, such as market demand, wide variations on the scenario, and mergers or acquisitions.

title: Inoculation methods, aggressiveness of isolates and resistance of peach palm progenies to Phytophthora palmivora

description: ABSTRACT Stem base rot (SBR) caused by Phytophthora palmivora is the main disease affecting peach palm in the nursery and in the field. This study aimed to: a) determine the most appropriate method for P. palmivora inoculation in peach palm; b) assess the aggressiveness of P. palmivora isolates; c) evaluate the resistance of peach palm progenies to P. palmivora. Experiments were carried out at “Embrapa Florestas” from March 2011 to March 2012. A descriptive rating scale was developed to assess SBR severity in peach palm. The disease severity was evaluated 7, 14, 21 and 28 days after inoculation. The conclusions were: a) injection at the stem base was the most effective method for P. palmivora inoculation; b) SA-5, SA-9, SA-10, SA-11, SA-14, SA-15, SA-16, SA-30 and SA-31 were the most aggressive P. palmivora isolates; and c) peach palm progenies T2, T4, T7, T9 and T15 showed resistance to P. palmivora.

title: Survey of Phaeomoniella chlamydospora in vineyard weeds

description: ABSTRACT Petri disease is serious, complex and difficult to control in vines worldwide. The main causal agent of this disease is the fungus Phaeomoniella chlamydospora. This fungus also occurs in the vineyard weed Convolvulus arvensis. In Brazil, this fungus was found only in grapevines. Thus, the aim of the present study was to carry out a phytosociological survey of weeds in an area with different vine rootstocks, as well as in a field of seedlings production, in an experimental area with vines and in different areas with commercial vineyards, besides verifying which weed species could be hosting the fungus P. chlamydospora. For the phytosociological survey of weeds, a square was randomly cast ten times at the site, followed by counting, identification and sampling of all species. To verify host species of the fungus, vascular tissue of plants was isolated in culture media and DNA extraction from the same plant tissue was carried out followed by PCR with specific primers of the fungus for the elongation factor gene (Pchlamy-EF-F 5’-CTCATTATCACATTTTGCTGC-3’ and Pchlamy-EF-R 5’-GAGAACAGTCAGTGATGAGC-3’). Considering all surveyed fields, 46 weed species were detected in 17 families, especially Asteraceae and Poaceae, which had the largest number of species. Using conventional or molecular methods, the fungus P. chlamydospora was not detected infecting weeds, which highlights that Petri disease occurs only in grapevines.
