title: Meloidogyne javanica parasitism on the vegetative growth and nutritional quality of carrots

description: ABSTRACT: Meloidogyne javanica is a plant-parasitic nematode that infects a wide range of vegetables. Its negative effects on crop yield and value are well documented. However, few studies have investigated the impact of the parasite on the nutritional value of vegetables. This study aimed to assess the effect of M. javanica parasitism on the vegetative characteristics, nematological parameters, chemistry composition and antioxidant activity of carrots. Seedlings were inoculated with 0 (control), 1000, 2500, or 5000 eggs and eventual second-stage juveniles (J2) of M. javanica. At 60 days after inoculation, plants were harvested and evaluated. Plants inoculated with 2500 eggs and J2 of M. javanica had higher root and tuber fresh weight than the control. Gall number increased with increasing inoculum density. The number of nematodes in the roots increased until 3000 specimens, decreasing thereafter. Proximate analysis revealed that plants inoculated with 1000 eggs and J2 of M. javanica or more had higher protein content in roots. In contrast, inoculation with 1775 nematodes or more resulted in a decrease in carotenoid content. There was no effect of inoculation on total phenolic content or antioxidant activity. Although, M. javanica infection did not have a marked impact on the nutritional quality of carrots, gall formation resulted in deformed roots of low commercial value.

title: How drying methods can influence the characteristics of mucilage obtained from chia seed and psyllium husk

description: ABSTRACT: The influence of drying methods (oven drying at 50 °C, and freeze drying) on the centesimal composition, functional characteristics and rheological properties of mucilage obtained from chia seed and psyllium husk were investigated. Results showed that high temperature of oven drying reduced fiber content, solubility, emulsion activity and emulsion stability of mucilage. All samples showed pseudo plastic behavior, with the best result produced by Heschel-Bulkley and Power Law models of chia and psyllium mucilage, respectively. These results will be helpful in selecting suitable drying methods depending on the functional and rheological properties desired of the chia and psyllium mucilage in a food product.

title: Seroprevalence of Corynebacterium pseudotuberculosis and Toxoplasma gondii in sheep in semi-arid region of Ceará state

description: ABSTRACT: The present study was conducted to investigate in 20 extensive sheep farms for the seroprevalence of Corynebacterium pseudotuberculosis (n=402) and Toxoplasma gondii (n=228). Enzyme-linked immunosorbent assay (ELISA) was used for the detection of antibodies to C. pseudotuberculosis/T. gondii. It was observed that C. pseudotuberculosis showed the highest prevalence in the region (34.07%) with statistically significant presence (p&lt;0.05) in ewes. Antibodies to T. gondii was reported in 14.91% of the animals studied. About C. pseudotuberculosis/T. gondii coinfection the categories of rams showed significant (p&lt;0.05) differences, suggesting that this gender could perpetuate the diseases in the flocks. It was concluded that the knowledge about the diseases in the region under study would facilitate the execution of prophylactic measures, especially against the diseases that pose risks to the public health and cause damages to the producer.

title: Glyphosate on shikimic acid on Urochloa plantaginea

description: ABSTRACT: Shikimic acid (SA) has witnessed a strong increase in recent years due to the increasing demand of the pharmaceutical and cosmetic industry. The SA is used as a precursor for the synthesis of oseltamivir phosphate (Tamiflu®), a potent viral inhibitor and is extracted from the plant Illicium verum Hook which has a limited availability. This article proposed the use of Urochloa plantaginea (Link.) webster and glyphosate, as an alternative source of SA. U. plantaginea plants with 3 - 4 tillers and 4 - 6 leaves were harvest at 3, 6, 9 and 12 days after application (DAT) of low rates of glyphosate. Samples were dried, extracted, analyzed by HPLC and LC-MS/MS. The maximum SA concentrations were observed at 6 days after glyphosate at 36 g.a.e.ha-1 was applied in plants of U. plantaginea with 4 to 6 leaves. The capability of this annual gramineae to produce elevated SA levels throughout the entire biomass affords its potential for a greater yield on a per hectare basis.

title: Locomotor response of diamondback moth (Plutella xylostella) populations to a neurotoxic insecticide under laboratory conditions

description: ABSTRACT: The present study aimed to evaluate changes in the locomotor activity of diamondback moth (Plutella xylostella) populations exposed to surfaces treated with the insecticide chlorantraniliprole under laboratory conditions. Diamondback moth populations from municipalities incorrectly using the insecticide [Camocim de São Félix, PE (CSF); Sairé, PE (SR); and Lajedo, PE (LJ)] and two laboratory populations from Recife, PE (RCF), and Viçosa, MG (VÇS) were exposed to dry insecticide residues in increasing concentrations. The following behavioral parameters of the populations were analyzed: walking time (WT), mean walking speed (MWS), and rest time (RT). Regarding RT, the SR and CSF populations demonstrated a behavior of irritability and increased WT with increased exposure concentration. The RCF population presented a contrasting response. The MWS values in the SR and CSF populations showed a decreasing trend with increased exposure concentration. The LJ and RCF populations showed no changes in terms of MWS. The RT values in the SR population decreased with increased insecticide concentration. In general, the SR and CSF populations presented a behavioral pattern different from that of laboratory populations. The changes in locomotor activity observed may result in lower control efficacy of the insecticide due to repellency or escape of insects. Regarding the effect of insecticide concentrations used in the populations, a defined pattern was not observed, and the effect alternated between an increase, a decrease, and an undefined pattern for the variables studied.

title: Transmission of exchange rate variation to Brazilian pulp export prices

description: ABSTRACT: The aim of this research was to examine the relationship between exchange rate variations and Brazilian export prices for cellulose, which is defined as the exchange rate pass-through, taking the period from January 2000 to March 2019 as a reference. The data were collected on the websites of the Ministry of Development, Industry and Foreign Trade - MDIC, the Institute of Applied Economics - IPEA and the Federal Reserve Bank of St. Louis - FRED. Thus, time series instruments were used, especially the Error Correction Vector Model. Results provided indications that the pass-through degree of exchange rate for cellulose export prices occurred incompletely in the total period and in the second sub-period, and was null in the first sub-period, representing that depreciation of rate exchange rates did not translate into significant competitiveness gains, as they did not significantly reduced export prices.

title: Clinical, hematological and histopathological aspects of experimental induction of laminitis in cattle through lipopolysaccharide infusion

description: ABSTRACT: The purpose of this research was to confirm the changes occurring in the foot system of the heifers challenged with lipopolysaccharides (LPS), at the clinical, serum and histological levels. We studied 16 clinically healthy heifers, 14 months of age, placed in a confinement system. All the animals were provided with an accelerometer collar to establish their activity. They were categorized into two groups: the LPS group (n=8), or those which were administered two intravenous applications of 2 mL containing 0.5 μg/kg of body weight of LPS, with a 24-hour interval and the Control group (n=8) which were given two infusions of 2 mL of saline solution in the same time interval. General clinical examination and blood collection were done at 0, 4 and 8 hours post the LPS challenges and analyses of the hemograms and paroxonese-1 were performed. The animals were then slaughtered on day 4 and the laminar tissue was collected for histological analysis. The LPS group revealed a lower total leukocyte count with heart rate and greater activity. None of the animals revealed any abnormal signs symptomatic of foot pathology after histological analysis. Hence, the challenge with LPS failed to induce any clinical and histological changes in the foot tissue compatible with laminitis.

title: Ventral slot in the clinical recovery of dogs with lateralized compression as a result of cervical intervertebral disc disease - 20 cases (2008-2018)

description: ABSTRACT: The objective of this study was to verify the clinical recovery of dogs that underwent ventral slot surgical decompression with lateralized compressions of the cervical spinal cord caused by intervertebral disc disease (IVDD). Twenty patients were selected in different degrees of neurological dysfunction with definitive diagnosis of lateralized compression by cervical IVDD. Postoperative clinical recovery was assessed in patients who had undergone at least two months of the surgical procedure. There was a satisfactory recovery in 19 dogs (95%) and unsatisfactory recovery in another (5%), showing a significant clinical improvement (p&lt;0.05) in the use of this technique in lateralized compression cases. The ventral slot promotes satisfactory clinical recovery of dogs with lateralized compression of the spinal cord caused by cervical IVDD and may be indicated as a surgical alternative.

title: Selectivity of a fishing gear used in the catch of Anomalocardia flexuosa in the Northeast of Brazil

description: ABSTRACT: A type of dredge was introduced as fishing gear along the extractive bank of Mangue Seco - PE from which the largest annual catch of Anomalocardia flexuosa in the world is extracted. This study was carried out with the objective of estimating the selectivity of the new fishing gear and quantitatively evaluating the length classes most compromised by the catches, especially considering 20 mm as the reference value. Specimens larger than this size are most likely to be mature. For the selectivity estimation, the methodology using codends (16 or 20 mm) and small meshed cover (2 mm) was used. To estimate the selectivity parameters, a logistic regression and the Bayesian approach were used. The transition between the state in which the specimen is invulnerable to the fishing gear and vulnerable occurs between 10 and 18 mm, using a 16 mm mesh, and using a 20 mm mesh, this transition is between 14 and 20 mm. Dredgers with 16 mm and 20 mm mesh compromise a large proportion of specimens smaller than 20 mm. If the intention is to protect this part of the population, measures such as total restriction of the 16 mm mesh and use of the 20 mm mesh should be necessary only in the months of less catching incidences, or increasing the mesh to 25 mm.

title: Whole-grain pan bread with the addition of jabuticaba peel flour

description: ABSTRACT: The objective of this study was to analyze the potential of the jabuticaba peel flour (JPF) as an ingredient in whole-grain bread. Pan bread formulations with different concentrations of jabuticaba peel flour were made: 0% (T0), 5% (T1), 10% (T2), and 15% (T3). Proximate composition, pH, water activity, color, phenolic compounds and antioxidant activity of bread were determined. The addition of JPF to the bread formulations led to a reduction of carbohydrate levels (51.14 to 46.55 g 100 g-1), lipids (4.79 to 3.35 g 100 g-1) and an increase in moisture (31.06 to 37.31 g 100 g-1) and ash (0.22 to 0.35 g 100 g-1). The fiber content increased up to three times, and the phenolic compounds up to seven times, thus increasing the antioxidant activity of the JPF-based bread when compared to the control. Bread made with the addition of JPF presented lower L* values (46.72 to 36.07) and higher a* values (3.10 to 9.07) compared to the control. Therefore, jabuticaba peel flour can be considered a potential ingredient for addition to whole-grain pan bread with desirable nutritional and functional characteristics.

title: Guanidinoacetic acid supplementation on growth performance and molecular mechanisms of lean mass gain in nursery pigs

description: ABSTRACT: The objective with the present study was to evaluate the effect of guanidinoacetic acid (GAA) on the growth performance of nursery piglets as well as a possible molecular mechanism of action on lean mass gain. Seventy-two pigs, weaned at 21 d, weighing 6.80 ± 1.2 kg were distributed in a completely randomized design into one of three dietary treatments (control, control + 1.2 g/kg GAA or control + 2.4 g/kg GAA) and 8 replicates per treatment. The control diet was an animal protein-free diet based on corn and soybean meal. Body weight, average daily weight gain, average daily feed intake and feed efficiency were evaluated at 35, 49, and 56 days. At the end of the experiment, one animal per pen was slaughtered and samples of the vastus lateralis muscle were collected for RT-qPCR and protein abundance analysis. Overall (from 21 to 56 d), GAA supplementation improved feed efficiency (P &lt; 0.03). Skeletal muscle of pigs fed with GAA diet had greater mRNA expression of Akt (P &lt; 0.04) and RPS6KB2 (P&lt;0.01). In conclusion, supplementation with 2.4 g/kg GAA to nursery piglets improves feed efficiency and activates molecular mechanisms important to lean mass gain.

title: Degree of moisture in seeds for the cryopreservation of orchids native to Brazil

description: ABSTRACT: The objective of this study was to determine the ideal moisture degree for the cryopreservation of Cattleya labiata Lindl. and Miltonia regnellii Rchb.f. orchid seeds. Orchid seeds were standardized in relation to the desired moisture degrees (4, 6, 8, 10, 12, and 15%) and were subjected to rapid freezing in liquid nitrogen (-196 °C) for 24 h; then, the seeds were defrosted and analyzed. For both orchid species, the seeds that were immersed in liquid nitrogen with 4% moisture content had the highest viability percentage, averaging 95% and 68% of viable seeds for C. labiata and M. regnellii, respectively. The seeds with 12% and 15% moisture content had no viable seeds. For the fresh mass of seedlings, there was no significant difference between moisture content treatments for either species.

title: Pre-incubation of ruminal inocula to assess in vitro gas production and digestibility

description: ABSTRACT: In vitro gas production techniques represent a valuable tool to describe the kinetics of ruminal degradation of food. However, the ruminal liquor used as a microbial inoculum has been a great source of variation and error. A standardization of this factor should contribute to assure the independence of food fermentation parameters from those of the inocula. In this research it was hypothesized that a controlled pre-incubation treatment of ruminal liquor could contribute to stabilize and homogenize the undigested residues of blanks and as a consequence, of the production of residual cumulative gas production (CGP). A pre-incubation (i.e. previous real incubation) of rumen inocula was developed with a simple substrate similar to the diet offered to donors at 1% w/v for 0, 1, 2 and 4 h (Control, Prei-1, Prei-2 and Prei-4 treatments respectively). Once the pre-incubation hours were completed, they were incubated with contrasting substrates and without substrate (i.e. blanks) in order to evaluate the CGP, in vitro digestibility of the DM and fermentation products. Although, the fermentative activity of the pre-incubated inoculums worked satisfactorily in the in vitro system, contrary to what was speculated, residues of the pre-incubation increased the variability and heterogeneity of variances among blanks. Consequently, it was concluded that the pre-incubations did not work to generate more homogeneous and less variable ruminal liquor for the in vitro gas production system.

title: In vitro fermentation of diets containing sweet potato flour as a substitute for corn in diets for ruminants

description: ABSTRACT: With the intensification of production systems, dairy cow feeding has undergone changes creating the need to increase substitute feed options, focusing on more efficient, modern, and sustainable alternatives. Few researches were carried out evaluating the inclusion of sweet potato flour as an energy source in substitution of maize for ruminants. The aim of this study was to evaluate the in vitro gas production of ground corn replacement by sweet potato flour at different levels. For in vitro gas production, four treatments were performed, consisting of corn replacement by sweet potato flour at the levels of 0, 33, 66, and 100%, in a diet consisting of corn silage, soybean meal, and ground corn. In vitro incubations were conducted in sealed bottles containing 50 ml of the inoculum prepared using ruminal fluid and 0.5 g of each treatment. Gas production was determined in 96 consecutive hours. The cumulative gas production was greater when the corn was 100% replaced by SPF (224 ± 1.45 and 231.9 ± 1.45 ml/g DMi for 0 and 100% of replacement, P = 0.01). Degradation rates were 7.10, 7.59, 8.08, and 8.59 ± 0.06% per hour for the 0, 33, 66, and 100% replacement rates, respectively (P&lt;0.001). There was also a difference (P = 0.002) in the lag time, in which diets with the highest SPF inclusion had a lower colonization time. In conclusion, sweet potato flour produced more gas and was more rapidly degraded than corn.

title: 3D printing as a diagnostic tool for congenital malformation in a brachycephalic dog

description: ABSTRACT: Congenital anomalies are hereditary or acquired, and their location and intensity are determining factors for the survival of animals. Some cases are rare, often unidentified, poorly reported and of unknown etiology. This paper reports a congenital malformation in a French bulldog, demonstrating the importance of accurate diagnosis for surgical decisions. The use of new technologies such as computed tomography and rapid prototyping enables the analysis of morphofunctional changes, resulting in excellent results for clinical cases in which it is difficult to identify and scale the anatomical deformities. Through this feature, it is possible to accurately recreate anatomical structures of interest, enabling greater assertiveness in deciding the treatment to be established, whether surgical or not. Castration of animals that survive this condition due to hereditary etiology is recommended.

title: Phytoplankton growth and microzooplankton grazing rates from NES-LTER transect cruises EN608, EN617, EN627.

description: Phytoplankton growth and microzooplankton grazing rates were measured from incubation experiments using the dilution method in the framework of the Northeast US Shelf Long-Term Ecological Research project. The dataset gathers plankton population dynamics rates obtained during cruises onboard the R/V Endeavor in winter 2018 (EN608), summer 2018 (EN617), and winter 2019 (EN627) along a North/South transect from Martha’s Vineyard to the shelf-break. This is an ongoing dataset reporting the first phytoplankton growth and microzooplankton rates used for a publication. The dataset includes only rates obtained from surface samples. Different light treatments were used to simulate different environmental conditions and to better understand the role of light on plankton population dynamics. Phytoplankton growth and microzooplankton grazing rates were measured for the total phytoplankton community (Chl-a concentrations) and for size fractions (Chl-a size fractionation) less than and greater than 10 µm. Phytoplankton growth and microzooplankton grazing rates, the first trophic interaction between primary producers and higher trophic levels, are essential parameters to assess the cycling and export of carbon in the ocean and to better understand marine food webs.

title: Epidemiological characterization of reported cases of brucellosis in cattle in the western region of the state of Santa Catarina, Brazil

description: ABSTRACT: Brucellosis is one of the most important and widespread bacterial zoonoses in the world. There are few epidemiological studies on brucellosis in cattle in the productive region of western Santa Catarina. Thus, the objective of this study was to characterize the epidemiological aspects of bovine brucellosis reported in this region from 2013 to 2018. Cattle data were provided by the Integrated Company for Agricultural Development of Santa Catarina (Companhia Integrada de Desenvolvimento Agrícola de Santa Catarina - CIDASC). The prevalence of the disease was evaluated in cattle and herds by means of temporal trend analysis and spatial distribution. Bovines with tests showing positive for brucellosis were analyzed for location (municipality) and year of confirmation of diagnosis. In the study period (2013-2018), 686,086 tests were performed for brucellosis, with a prevalence rate of 1.11% (7,586/686,086). Among the 80,171 herds tested, 0.95% were found to be positive (764/80171). The odds ratio of brucellosis occurrence in cattle increased significantly in 2015 (OR = 1.55) and 2016 (OR = 1.97) and decreased in 2014 (OR = 0.47) and 2017 (OR = 0.97). The disease is present in cattle in 61.07% (80/131) of the municipalities where the tests were performed. Results showed that brucellosis is endemic in the region.
