title: Lipid profile of broiler meat from different crosses raised in alternative system

description: ABSTRACT The objective was to evaluate the lipid profile of chickens from different genotypes. The design was completely randomized arranged in factorial scheme (5x2), being 5 genotypes (New Hampshire - NHS, Gigante Negra de Jersey - GNJ, Índio Gigante - IG; poultry from the cross between IG and NHS breeds - IG x NHS and between IG and GNJ breeds - IG x GNJ) and two genders, with five replicates and three poultry per replicate, totaling 150 birds, slaughtered at 105 days. Lipid profile analyzes were performed on the breast and thigh. Estimates of the enzymatic activities related to lipid metabolism were calculated, in addition to the atherogenicity and thrombogenicity indexes. The IG and IG x NHS genotypes showed higher levels of arachidonic acid and DHA. Higher levels of saturated and monounsaturated fatty acids were observed in the breast for IG x NHS and NHS genotypes, respectively. Higher averages of polyunsaturated fatty acids and omega 3 were observed for the IG and IG x NHS genotypes. The genotype IG x NHS and the females presented better characteristics of meat quality, for offering a greater source of omega 3.

title: Differential Hormetic Response of Fenoxaprop-p-Ethyl Resistant and Susceptible Phalaris minor Populations: a Potential Factor in Resistance Evolution

description: ABSTRACT: Resistance evolution in weeds against all major herbicide groups demand investigations to identify various factors responsible for resistance development. Herbicide hormesis has not yet been included in the list of factors promoting the evolution of resistance. Studies were conducted to evaluate the degree of hormesis in fenoxaprop-p-ethyl susceptible and resistant Phalaris minor to provide a first indication of whether hormesis is a potential factor in the development of resistance. In the first experiment, a wide range of doses up to 160% of the recommended field rate was used to identify potential hormetic doses for resistant and susceptible P. minor populations. Doses below 40% have been designated as potential hormetic doses. In the second experiment, ten different doses of fenoxaprop below 40% (0, 2, 4, 8, 12, 16, 20, 24, 28 and 32% of the recommended rate) were sprayed at the 4-5 leaf stage of both resistant and susceptible P. minor populations. At fifteen days after spraying, dose range of 2-12% and 2-20% caused a significant increase (up to 22% and 24%) in growth traits of susceptible and resistant populations, respectively. At maturity, dose range of 2-12% for susceptible and 2-24% for resistant populations caused a significant increase (up to 20% and 57%) in growth and seed production potential (13% and 17%), respectively. The upper limit of the hormetic dose range (16 to 24%) for the resistant population was inhibitory for the susceptible populations. These results indicate that fenoxaprop hormesis could play a vital role in the evolution of fenoxaprop resistance in P. minor.

title: Hydrothermal Synthesis to Water-stable Luminescent Carbon Dots from Acerola Fruit for Photoluminescent Composites Preparation and its Application as Sensors

description: Carbon dots (C-dots) possess the attractive properties of high stability, low toxicity, good water solubility, simple synthetic routes as well as size and excitation-dependent photoluminescence (PL).The aim of this work was to synthesize photoluminescent C-dots by hydrothermal method using acerola fruit (Malpighiaemarginata) as a row material, since this fruit contains large number of organic molecules. Studies about the optimal synthesis conditions were performed, where these organic molecules were converted into C-dots by hydrothermal carbonization at 180 ºC for 18 h. The C-dots exhibited a green emission light at 459 nm when excited under UV-light ( λ ex= 370 nm). These nanomaterials were also successfully used to prepare C-dots/poly (vinyl alcohol) luminescent composites (C-dots/PVA). Both C-dots and C-dots/PVA composite films were investigated by using colorimetric visual sensor for Fe3+ metal ions detection. The results show that the prepared C-dots and C-dots/poly presented strong green emission light. The emission spectra of above materials were quenched in the presence of Fe3+ ions. Thus, highly specific “turn off” fluorescence sensing of Fe3+ was achieved using fluorescent C-dots. Regarding, this work describe that the polymeric films as sensors of metallic ions in aqueous solution appears as a new perspectives to design new composite materials.

title: Specialization and productive diversification: a space panel model for the mineral extraction industry in Minas Gerais, 2000-2010

description: Abstract The Mining Industry is important for Minas Gerais. In the 2000s, it doubled its share of state added value, contributing 6.9% of GDP and 20% of industrial GDP in 2010. However, its local effects on regional development are ambiguous and poorly studied. This article aims to analyze the net effects of mining on the complexification of the municipal productive structure of the largest miners in the state. We used a set of regional and urban economics indicators as well as spatial panel modeling. Empirical evidence indicates that during the 2000s there was a relative loss of the regional specialization and concentration concentration differentials in the sectors of High and Medium Technological Intensity, Traditional Productive Services and Modern Productive Services.

title: Quality of ‘Oso Grande’ strawberries is affected by O2, CO2 and N2O concentrations during controlled atmosphere storage

description: ABSTRACT Consumers around the world appreciate strawberries for their taste. They have low calories and high concentrations of soluble fibers, vitamin C and flavonoids. This paper verified the combined effect of O2, CO2, and N2O levels on ‘Oso Grande’ strawberries stored at 10° C, under controlled atmosphere (CA). Five different gas mixtures were used: 0.03 kPa CO2 + 20 kPa O2, 80 kPa N2O + 20 kPa O2, 90 kPa O2 + 10 kPa N2, 60 kPa O2 +40 kPa CO2, and 20 kPa O2 + 20 kPa CO2 + 60 kPa N2O. The lowest incidence of postharvest decay was observed with treatment20 kPa O2 + 20 kPa CO2 + 60 kPa N2O, followed by 80 kPa N2O +20 kPa O2 and 90 kPa O2 + 10 kPa N2. The treatment 60 kPa O2 + 40 kPa CO2 induced an increase in the production of acetaldehyde and ethanol, and these levels were considered inadequate for human consumption. The first factor, named senescence, displayed a positive correlation with soluble solids, luminosity, hue angle, firmness and incidence of decay. hpsThe second factor, named CA-induced injury, showedhps that total acidity correlated negatively with ethanol and acetaldehyde levels. Hiehpsrarchical cluster analysis indicated that strawberries stored underhps80 kPa N2O + 20 kPa O2hps for 14hps hpsdays more closely resembled the quality of fresh fruit at the moment of harvesthps. ‘Oso Grande’ strawberries stored at 10 ºC under 80 kPa N2O + 20 kPa O2 and 90 kPa O2 +10 kPa N2 were in better conditions, with no metabolic alterations, showing that these are the ideal storage conditions.

title: Diet and resource sharing by two Pimelodidae species in a Southeastern Brazilian reservoir

description: Abstract: Fish can vary their diet and feeding dynamics according to biotic and abiotic factors. There is insufficient knowledge regarding these factors in reservoirs, which limits the management of these areas. The aim of this study was to determine the diet of two related and most collected fish species, verify the influence of biotic and abiotic factors on their diet, and also verify the existence of resource sharing by them in an upstream Brazilian reservoir. Fish abundance in the reservoir was calculated and data were provided by 176 specimens of Iheringichthys labrosus (Lütken, 1874) and 255 specimens of Pimelodus maculatus Lacépède, 1803 collected in Camargos reservoir, MG, Brazil. Stomach contents were analysed through the frequency of occurrence and volumetric methods. PERMANOVA analysis was done to evaluate the influence of biotic (Species and Size class) and abiotic factors (Season and Site) on the diets. The Alimentary Index (AI) and feeding overlap Index (Pianka) were also estimated. A NMDS analysis was conducted to visualize the food categories responsible for interspecific difference. The ingested items were grouped into 18 categories, of which 17 were found in both species. Feeding resources were significantly related to the biotic (Species: Pseudo F = 2.583, P = 0.001; Size Class: Pseudo F = 1.646, P = 0.001) and abiotic (Season: Pseudo F = 2.458, P = 0.006) factors. I. labrosus showed an invertivorous diet while P. maculatus an omnivorous diet and both species were not exclusively benthophagus as typically reported. Food overlap occurred intraspecifically and interspecifically (Pianka 0.61 to 0.97 and 0.61 to 0.66, respectively) and overlap also occurred in three of the four analysed seasons (Pianka 0.66 to 0.91). The diet overlap found between two of the most fished species and the low fish productivity may indicate the limitation of resources in this reservoir and should be considered for management of this area.

title: Embolic stroke of undetermined source (ESUS) cohort of Brazilian patients in a university hospital

description: ABSTRACT Embolic stroke of undetermined source (ESUS) is an important group of cryptogenic strokes that are in evidence due recent ongoing trials. We reviewed medical records at discharge from the stroke unit of all patients who met ESUS criteria and attended our institution between February 2016 and July 2017. Among 550 stroke patients, 51 had ESUS. We found that hypertension (60%), diabetes mellitus (34%), and smoking (36%) were the most prevalent risk factors. The mean National Institutes of Health Stroke Scale (NIHSS) scores were 7 at admission and 4 at discharge, while median scores on the modified Rankin scale were 0 and 2 at admission and discharge, respectively. Our sample had similar ages, risk factors prevalence and NIHSS scores at admission and discharge when compared with European and North American cohorts. Although a small cohort, our study suggests that the ESUS population is similar in countries with different health financing.

title: Optimization of ultrasound-assisted extraction of procyanidins from perilla seed hull and their antioxidant activities in vitro

description: Abstract Ultrasound-assisted extraction (UAE) was used to extract procyanidins (PC) from the perilla seed hull. Four independent variables, namely, liquid-to-solid ratio, ethanol concentration, UAE time, and UAE temperature were investigated. Response surface methodology was performed on the basis of results of single-factor tests. The optimal conditions for PC extraction were as follows: a liquid-to-solid ratio of 15:1, an ethanol concentration of 62%, a UAE time of 29 min, and a UAE temperature of 53 °C. Under these conditions, the experimental yield of PC was 2.185 mg/g (n = 3), which is correlated with the predicted value of 2.2 mg/g. The extracted and purified PC showed excellent antioxidant activity against 2,2-diphenyl-1-picrylhydrazyl, hydroxyl, and 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) radicals in vitro.

title: Occurrence of gastric ulcers and serum gastrin levels in jumping horses

description: ABSTRACT The aim of this study was to determine the occurrence of EGUS and to quantify serum gastrin levels in jumping horses during competition season and interseason period. Forty jumping horses, competing at high level were randomly allocated into two groups, the Training Group: twenty jumping horses undergoing intense training and participating in competitions, and the Rest Group: twenty jumping horses in the interseason (resting period). The gastroscopic examinations and blood samples of the horses in the training group were performed 1-2 days following the competition while in the horses of the rest group, following 4 weeks of rest. The serum gastrin levels were measured at two different times: pre-feeding and two hours after feeding the horses (postprandial) by ELISA kit. Gastric lesion score data were compared by the Mann-Whitney U test (α= 0.05) and the mean gastrin values were compared between the groups and between the two moments by the paired tet tests, respectively (α= 0, 05). Squamous gastric ulcers were detected in 42.5% of all jumping horses examined independent of the period, competition season or interseason. Serum gastrin levels were significantly higher in the Training Group with no difference between pre-feeding and postprandial values.

title: Investigation of phenolic profiles and antioxidant activities of some Salvia species commonly grown in Southwest Anatolia using UPLC-ESI-MS/MS

description: Abstract Aerial parts of Salvia albimaculata Hedge & Hub.-Mor., Salvia potentillifolia Boiss & Heldr. ex Bentham. and Salvia nydeggeri Hub.-Mor. from Soutwest Anatolia, Turkey were evaluated to determine their phenolic compounds and antioxidant properties. According to the ultra performance liquid chromatography with electrospray ionization tandem mass spectrometry (UPLC-ESI-MS/MS) analysis results, caffeic acid (3582.8 ± 2.5 μg/g, 2956.5 ± 4.6 μg/g and 2457.7 ± 3.1 μg/g) and 3,4-dihydroxy benzoic acid (1846.2 ± 3.1 μg/g, 2019.1 ± 2.2 μg/g and 1901.3 ± 1.5 μg/g) were found to be in the highest concentrations in S. potentillifolia, S. albimaculata and S. nydeggeri, respectively. Total amounts of phenolics and flavonoids were determined highest in ethyl acetate extracts of samples and varied from 62.4 ± 0.1 to 55.4 ± 0.0 µg PEs/mg and from 296.8 ± 1.4 to 198.4 ± 1.5 µg QEs/mg, respectively. Antioxidant activity of S. potentillifolia was found to be higher than the others for ABTS•+ and β-carotene linoleic acid assays (SC50 = 49.8 ± 0.9 and IC50 = 26.1 ± 0.6 µg /mL, respectively) while S. albimaculata was found to be higher for DPPH• assay (SC50 = 227.4 ± 1.1 µg/mL).
