title: The advertising value of Twitter Ads: a study among Mexican Millennials

description: Abstract Purpose: This study set out to measure the perceived Advertising Value of Twitter ads on a large sample of Mexican Millennials. Design/methodology/approach: An online survey was used to collect data among 630 university students. The hypothesized antecedents of Advertising Value were Informativeness, Entertainment, Irritation and Credibility. The model was estimated using Partial Least Squares. Findings: Results indicate Informativeness and Entertainment were the strongest predictors, with Credibility in third place. In addition, Credibility displayed gender effects: it was significant for female respondents but not for males. Irritation failed to reach statistical significance in most subsamples, suggesting Twitter ads are more acceptable to Millennials than other advertising formats. Originality/value: Millennials tend to dismiss traditional advertising formats. At the same time they are heavy users of Social Networking Sites. This research provides the first empirical estimation of the Ducoffe model of Advertising Value in the microblogging service Twitter, and the first application of this robust model of web advertising to a Latin American sample. Our results have important implications for both regional and global brands targeting Millennials.

title: CHICKENS CHALLENGED AGAINST Salmonella enterica SOROVAR ENTERITIDIS AND Eimeria tenella AND TREATED WITH ORGANIC ACIDS

description: Abstract A commercial organic acids compound was assessed, added to feed, to control Salmonella Enteritidis. Broilers were challenged with Salmonella Enteritidis and Salmonella Enteritidis associated with Eimeria tenella. Five hundred and four day-old Hubbard® females chicks were used in a completely randomized design in a 2x3 factorial, a total of six treatments with six replications and being 14 birds the experimental unit. Intestinal pH, cecum lesion score, oocyst faecal counts and the presence of Salmonella in the cecal tonsils and spleen of broilers were investigated. Broilers that were challenged only with S. Enteritidis that received the compound in test showed lower frequency of bacteria isolation in lymphoid organs. Besides, decreased number of oocysts of E. tenella was observed and the intestinal lesion scores caused by infection was lower. Organic acids promoted a benefit on broilers intestinal health with positive effects on the control of Salmonella Enteritidis with Eimeria tenella.

title: Relationship between cognition and frailty in elderly: A systematic review

description: OBJECTIVE: The aim of this study was to analyze the relationship between cognition and frailty in the elderly. METHODS: A systematic review on the currently existing literature concerning the subject was carried out. The search strategy included LILACS, SCOPUS, SciELO, PsycINFO, PubMed and Web of Science databases. RESULTS: A total of 19 studies were selected for review, from which 10 (52.6%) were cross-sectional and 9 (47.4%) longitudinal, and the majority Brazilian. All of the studies established a link between cognition and frailty. There was a relationship between components of frailty and the cognitive domains. Risk of Mild Cognitive Impairment (MCI), dementia and mortality were all evidenced in the relationship between frailty and cognitive impairment. CONCLUSION: The theory remains limited, but results show the variables that appear to be linked to cognition and frailty in elderly. This data can help in implementing actions to improve the quality of life among elderly.

title: PICROSIRIUS RED AND MASSON’S TRICHROME STAINING TECHNIQUES AS TOOLS FOR DETECTION OF COLLAGEN FIBERS IN THE SKIN OF DOGS WITH ENDOCRINE DERMATOPATHOLOGIES

description: Abstract Canine endocrinopathies, such as hypothyroidism and hyperadrenocortism,induce typical dermatological alterations. Collagen fibers are significant for the maintenance of structural integrity,as well as in the determination of tissue function. This study aimed at assessing the coloration caused by Picrosirius Red staining under circular polarization and Masson Trichrome staining, as tools to quantify the total collagen in the skin of dogs exhibiting endocrine dermatopathies. Skin samples taken from dogs with hypothyroidism and hyperadrenocorticism were stained using Hematoxylin and Eosin (HE), Masson’s Trichrome (MT) and Picrosirius Red (PSR). The animals with hyperadrenocorticism revealed a higher percentage of collagen area than did the animals with hypothyroidism PSRp (hypothyroidism = 43.76 ± 0.8255 and hyperadrenocorticism = 47.08 ± 0.8584). The percentage of the collagen area using MT between the groups is given in parenthesis (hypothyroidism = 52.06 ± 0.9371, hyperadrenocorticism = 61 ± 0.7529 and control = 56.88 ± 0.64) (p &lt;0.05). It is therefore, evident that the special stains employed are useful in estimating the percentage of collagen area in the skin, as they revealed that dogs with hypothyroidism had lower collagen deposition whereas those animals with hyperadrenocorticism showed higher quantity of collagen in the dermis.

title: PARASITIC EFFECT BY Haemonchus contortus ON LEUKOCYTE OXIDATIVE METABOLISM

description: Abstract The immune response to hemoncosis can be modulated by the Th2 profile, and the main effector cells responsible are eosinophils responsible for a efficient elimination of the parasite, but when it is modulated by the Th1 profile, neutrophils are the main effector cells, responsible for a more deficient parasitic elimination, probabely, because in vitro tests have shown that the parasite depresses the oxidative metabolism of phagocytes. Thus, this study aimed to evaluate if the degree of parasitic infection observed by the amount of eggs per gram of feces (EPG) of Haemonchus contortus interferes in the leukogram, and if it impacts on leukocyte oxidative metabolism in sheep naturally affected by hemoncosis. 39 adult male sheep without alterations in the physical examination, except for mucosal collor, were separated into 4 groups according to parasitic infection 0-350 (n = 15), 400 to 1000 (n = 10), 1100. -2000 (n = 7) and 2100-4700 (n = 7). Significant positive correlation was observed between EPG and neutrophils (r=0.56P=0.0003) and significant negative correlation between EPG and eosinophils (r=-0,56,P = 0.0012) and EPG and leukocyte oxidative metabolism (P = 0.0001), allowing to conclude that there is a relationship between effector cells and the severity of parasitic infection in sheep naturally infected with hemoncose, and the high parasitic infection promotes decreased leukocyte oxidative metabolism.

title: Cardiorespiratory Optimal Point in Professional Soccer Players: A Novel Submaximal Variable During Exercise

description: Abstract Background: Maximal oxygen consumption (VO2max) and ventilatory threshold (VT) obtained during a cardiopulmonary exercise test (CPX) are used in the evaluation of athletes. However, the identification of these variables may sometimes be unreliable, which limits their use. In contrast, the cardiorespiratory optimal point (COP) is a submaximal variable derived from CPX with objective measurement and prognostic significance. However, its behavior in athletes is unknown. Objective: To describe the behavior of COP in professional soccer players and its association with VO2max and VT. Methods: VO2max, VT and COP were obtained retrospectively from 198 soccer players undergoing maximal treadmill CPX using ramp protocol. COP was defined as the lowest value of the ventilation/oxygen consumption ratio in a given minute of the CPX. The soccer players were stratified according to their field position: goalkeeper, center-defender, left/right-back, midfielder and forwarder. Continuous variables were compared using unpaired Student t test or ANOVA, or Mann-Whitney test or Kruskal-Wallis test depending on their distribution, and categorical variables were compared using chi-square test. Pearson correlation was used to test the association between COP and other ventilatory variables. A level of 5% was used for statistical significance. Results: COP (mean ± SD) was 18.2 ± 2.1 and was achieved at a speed 4.3 ± 1.4 km.h-1 lower than that achieved at the VT. While VO2max (62.1 ± 6.2 mL.kg-1.min-1) tended to be lower in goalkeepers (p &lt; 0.05), the COP did not vary according to field position (p = 0.41). No significant association was observed between COP and VO2max (r = 0.032, p = 0.65) or between COP and VT (r = -0.003, p = 0.96). Conclusion: COP can be easily determined during submaximal exercise performed with incremental speed in soccer players and does not vary according to the athlete’s field position. The absence of association with VO2max and VT indicates that COP provides distinct and complementary information to these variables. Future studies are needed to determine the practical implications of COP in assessing athletes. (Int J Cardiovasc Sci. 2018; [online].ahead print, PP.0-0)

title: Fallow Reduces Soil Losses and Increases Carbon Stock in Caatinga

description: ABSTRACT This study aimed at evaluating whether 10 years of fallow was sufficient to restore a degraded hillslope in the semi-arid Caatinga biome, Brazil. For this purpose, runoff, erosion, loss of nutrients and organic carbon were measured on two comparable hillslopes: one was left fallow and the other degraded caused by overgrazing. Fallow management reduced runoff (36%), soil loss (65%) and organic carbon loss (81%) in comparison with the degraded hillslope. However, the fallow did not significantly reduce nutrient loss. Animal grazing has been shown to influence the nutrient cycle in the soil. The loss of organic carbon shows significant correlation with the loss of other nutrients, and may be used to estimate nutrient loss. Results show that a decade of fallow did not promote significant changes in the loss of nutrients, but was enough to reduce runoff, erosion and loss of organic carbon.

title: A digital approach for design and fabrication by rapid prototyping of orthosis for developmental dysplasia of the hip

description: Abstract Introduction Immobilization in a hip spica cast is required in surgical and nonsurgical treatments for children aged three months to four years diagnosed with developmental dysplasia of the hip. Skin complications are associated with the use of the spica cast in 30% of the cases. This research explores the use of photogrammetry and rapid prototyping for the production of a lighter, shower friendly and hygienic hip orthosis that could replace the hip spica cast. Methods Digitalized data of a plastic dool was used for design and fabrication of a customised hip orthosis following four steps: 1) Digitalization of the external anatomical structure by photogrammetry using a smartphone and open source software; 2) Idealization and 3D modeling of the hip orthosis; 3) Rapid prototyping of a low cost orthosis in polymer polylact acid; 4) Evaluation tests. Results Photogrammetry provided a good 3D reconstruction of the dool's hip and legs. The manufacture method to produce the hip orthosis was accurate in fitting the hip orthosis to the contours of the doll. The orthosis could be easily placed on the doll ensuring mechanical strength to immobilize the region of the hip. Conclusion A new approach and the feasibility of both techniques for hip orthosis fabrication were described. It represents an exciting advance for the development of hip orthosis that could be used in orthopedics. To test the effectiveness of this orthosis for developmental dysplasia of the hip treatment in newborns, material and mechanical tests, design optimization and physical tests with patients should be carried.

title: Construction and analysis of specialized care access performance indicators of SUS

description: ABSTRACT This study aims to identify information to be used in order to analyze the performance of access to secondary health care. The accesses to the specialty of digestive surgery of the Ribeirão Preto State Hospital (HERP) and the Américo Brasiliense State Hospital (HEAB) were analyzed. Thirty-one actors, in 16 health organizations, were interviewed, with the purpose of identifying performance indicators. The indicators identified for both were: ‘distribution of vacancies by municipality’, ‘situation after the first consultation’ and ‘requests for consultation (PI)’. In access to HERP, the ‘time for screening’ was added. The data for analysis were extracted from the Assistance Regulation Support System (Sara), used only to access the HERP; and the system of the Clinical Hospital of Ribeirão Preto Medical School (Athos module), used in both. This information can be useful for characterizing processes, comparing them and assist in the identification of improvement opportunities by making them more transparent to those involved. Efficient access allows rational use of resources and increased patient access to services, as it enables reduction of waste, idleness and waiting time.

title: Physiological performance of wheat seeds treated with micronutrients and protection products during storage

description: Abstract: Seeds with high quality are one of the important factors to consider in the crops establishment on field. Therefore, the physical and physiological quality of wheat seeds treated with mixes of micronutrients including zinc and protective products were aimed. The wheat seeds were analyzed in a factorial scheme 5x3x4, with five storage time: 0, 60, 120, 180 and 240 days; three micronutrients: micronutrients 1 (1% Mn; 0.1% Mo; 10% Zn); micronutrients 2 (0.3% B; 0.3% Co; 3% Zn) and no micronutrients, and four protective products: untreated seeds, polymer (Colorseed He), fungicide carboxin + thiram (Vitavax® Thiram 200 SC) + insecticide thiamethoxam (Cruiser® 350 FS) and polymer + fungicide + insecticide. After treatment, the seeds were stored under uncontrolled conditions for 240 days and at intervals of 60 days, the germination, accelerated aging and moisture content were determined. Wheat seeds untreated and treated with polymer have the best physiological performance during storage, regardless micronutrients treatments. The wheat seeds treated with carboxin + thiram + thiamethoxam and polymer + carboxin + thiram + thiamethoxam can be storage up to 120 days, under uncontrolled conditions, regardless micronutrients treatments. The seed treatment does not alter the moisture content of wheat seeds.
