title: Use of eugenol for anesthesia of lesser guitarfish Zapteryx brevirostris (Rhinobatidae)

description: Abstract Anesthesia can be utilized as a non-lethal procedure to allow easy handling of teleosts and elasmobranchs in captivity or in the wild. For this, anesthetic protocols need to be established according to the species. The aim of this study was to determine the ideal concentration of eugenol for anesthesia of Zapteryx brevirostris. Four concentrations were tested: 21.25, 42.50, 85.00 and 170.00 mg L-1 (ratio of 1:5 with absolute ethanol). The perfect concentration of eugenol for this species was 85.0 mg L-1 , which enabled up to 300 seconds of work on the fish, without any response to handling.

title: Broiler Chicken Meat Inspection Data in Brazil: A First Glimpse into an Animal Welfare Approach

description: ABSTRACT We aimed to study the potential use of carcass condemnation data of broiler chicken slaughterhouses in Brazil as indicators in an animal welfare monitoring program, and to identify points to be addressed to increase data reliability. Data from 2010 to 2015 in the states of Paraná (PR), Santa Catarina (SC) and Rio Grande do Sul (RS) were used. Fractures and bruising were recorded together, representing the most prevalent welfare problem, followed by skin lesion or inflammation. In PR, progressive increases on injury, arthritis, ineffective bleeding, and air sacculitis condemnation may reveal important welfare aspects. High correlation between AWI within PR was more commonly observed than in RS and SC, perhaps as a result of earlier implementation of local meat inspection standardization. Principal component analysis showed changes on condemnation data pattern in PR after standardization, pointing injury and Escherichia coli problems as the main causes for condemnation related to animal welfare. There is considerable potential to improve animal health and welfare surveillance using meat inspection structure that is already in place for food safety purposes, provided that the competent authority harmonizes the procedure of meat inspection among the States, sets specific animal welfare outcomes to be monitored, and integrates condemnation, transport and flock data. It seems crucial to update data collection to establish a routine that allows risk analysis regarding both food safety and animal welfare. In this regard, cooperative work between Federal Inspection and companies seems an interesting approach to promote transparency of the production processes, which would benefit society and animals.

title: Does intensive feeding frequency affect growth performance of common snook Centropomus undecimalis (Bloch, 1792)?

description: Abstract Salt water recirculation systems using automatic feeders are a new frontier for marine aquaculture. It is possible to decrease the vulnerability of the traditional fish farming in open systems and reduce wasteful feeding and discharge of effluents, as well as increase the economic returns. An experiment with common snook fingerings (4.31 ± 1.42 g and 8.4 ± 1.0 cm) was performed. Three feeding treatments were evaluated: six, twelve and eighteen feeding times per day. Each treatment had three replications. Among the three tested frequencies (fed 6, 12 and 18 times a day), the feeding frequency of 12 times per day (every two hours) showed the best values of the parameters evaluated for production performance. The final weight values, condition factor, specific growth rate and daily weight gain of the treatment 12 feeding times per day were all significantly higher than the lower and higher frequencies. Our results demonstrate that high feeding frequency is not synonymous of higher performance, but is extremely necessary to find out the best range for the target species. Besides, this relationship between feeding frequency and growth performance might change over weight range. Therefore, future studies should address higher weight ranges for comparison to our results.

title: Characterization of neurological soft signs in a Brazilian sample of stable patients with schizophrenia

description: Abstract Introduction: Neurological soft signs (NSS) have been considered one of the target features and a potential endophenotype for schizophrenia. The present study aimed to characterize NSS in a sample of patients with chronic schizophrenia and to compare them with healthy control individuals. Methods: In this study, we evaluated the presence of NSS in a sample of stable patients (n = 24) diagnosed with schizophrenia according to DSM-IV criteria, recruited at the Schizophrenia Outpatient Clinic of Instituto Raul Soares, Belo Horizonte, state of Minas Gerais, southeastern Brazil. Assessment was made with the Brief Motor Scale (BMS), and extrapyramidal symptoms (EPS) were evaluated with the Simpson-Angus Scale (SAS) and the Abnormal Involuntary Movement Scale (AIMS). A control group (n = 21) was also submitted to the same battery of tests. Results: We observed a significant difference in relation to BMS and SAS scores (p &lt; 0.0001), revealing that individuals with schizophrenia present more NSS and EPS than healthy ones. BMS total scores correlated positively with SAS scores (r = 0.495, p = 0.014), but not with AIMS scores, indicating that NSS could be influenced by the intensity of EPS. Nevertheless, we observed that this relationship remained only for motor coordination tasks (r = 0.550, p = 0.005), while motor sequencing tasks were not influenced by EPS (r = 0.313, p = 0.136). Conclusion: The results suggest that NSS are more frequent in patients with schizophrenia and that motor sequencing tasks could be more specific to the syndrome.

title: Wollastonite to hinder growth of Aspergillus niger fungus on cotton textile

description: Abstract Effects of Aspergillus niger was investigated on the strength of cotton textile specimens impregnated with nano-wollastonite, and then compared with normal specimens. Cotton strips were cut and prepared in warp and wept directions according to the standard specifications ASTM D-5035. Results showed that incubation of A. niger on specimens for three months resulted in a significant decrease in tensile stress as well as weight mass change in both directions. Impregnating specimens with NW ameliorated the negative effects of fungal attack on tensile stress to a considerable extent. Moreover, weight change was significantly decreased. It is concluded that NW positively protect cotton textile against A. nigra; the ultimate NW-content should be studied in complimentary studies.

title: Evaluation of the antimicrobial activity of pecan nut [Carya illinoinensis (Wangenh) C. Koch] shell aqueous extract on minimally processed lettuce leaves

description: Abstract Pecan nutshell is a residue from food industry that has potential to be used as biopreservative in foods. The objective of this study was to evaluate the antimicrobial activity of pecan nutshell aqueous extract in vitro and its effectiveness to inhibit spoilage microorganisms on lettuce leaves. The results indicate that the aqueous extract presents inhibitory activity against important foodborne pathogenic bacteria such as Listeria monocytogenes, Salmonella Enteritidis, Staphylococcus aureus, Bacillus cereus, Aeromonas hydrophila and Pseudomonas aeruginosa. Antimicrobial activity was not observed against Corynebacterium fimi, Clostridium perfringens, Escherichia coli, and the phytopathogenic fungi tested. When applied onto lettuce leaves, pecan nutshell extract reduced the counts of mesophilic and psychrotrophic bacteria in 2 and 4 log CFU/g, respectively, during storage of leafy for 5 days at refrigeration temperature (5 °C). The extract was not effective to inhibit yeast on lettuce leaves. Thus, the aqueous extract of pecan shell showed great potential to be used as a natural preservative in foods, acting mainly in the inhibition of spoilage and pathogenic bacteria.

title: Explanations, conceptions and obstacles about the origin of species in High School students in Argentina

description: Abstract: Although there exists a great deal of research that analyzes the way in which the students explain adaptive evolution, few studies address how they explain the origin of new species. In this work, we characterize, based on a qualitative interpretative methodology, the way in which students in a secondary school in Argentina explain the origin of new species. For this purpose we use an open questionnaire in which we ask the students to explain the origin and extinction of certain species. From the answers we identified two explanatory patterns based on the notion of adaptation and a third on the hybridization. We interpret these responses in terms of a representational hierarchy ranging from the ideas most specifically linked to the cases discussed to the epistemological obstacles that constitute the most general modes of thought underlying.

title: Study of the consumers of ready-to-drink juices and fruit nectars

description: Abstract Juices and fruit nectars are an important segment of the beverage market in Brazil. The aim of this study was to analyze and characterize the profile of consumers of ready-to-drink juices and fruit nectars. A semi-structured questionnaire was applied to 389 patrons, intentionally and conveniently, when they approached the shelves. The chi-square test was applied to associate sociodemographic variables and consumption profile of the beverages with the type of establishment. Logistic regression models were developed to evaluate the variables associated with nectar acquisition. The level of education and knowledge about the beverages were significantly related. Practicality was the main reason that led respondents to consume these drinks, followed by quality and price, with the latter being associated with the level of education. Nectar was the most purchased option, and this choice was associated with increasing age and education, price and practicality. The consumption of juices and nectars with no added sugar was lower compared with traditional beverages. The information in the labels of these beverages was not sufficiently clear, for most of the participants. The most mentioned brand by the interviewed was the one with better sensory preference, regardless of flavour and the blinded or informed analysis.

title: Toxoplasma gondii: isolation, biological and molecular characterisation of samples from free-range Gallus gallus domesticus from countryside Southeast Brazil

description: Abstract Toxoplasma gondii presents a high prevalence worldwide, infecting several animals. Felines are considered the definitive hosts and among the intermediate hosts we highlight mammals and birds. The man can become infected by ingesting tissue cysts present in birds and mammals. Biological and molecular aspects of T. gondii allows a better understanding of the epidemiology of toxoplasmosis. This work is a serologic screening of 58 chickens grown (Gallus gallus domesticus) for human consumption in Espírito Santo State, by means of indirect haemagglutination assay (IHA). Thirteen chickens tested positive for anti-T. gondii antibodies. The heart and brain of five positive chickens were harvested, treated with pepsin and inoculated separately, in two Swiss mice, intraperitoneally. Tachyzoites were observed in the peritoneum of all the animals, between seven and 10 days after the inoculum. Ten isolates were obtained and biologically characterised in BALB/c mice inoculated with 101 to 104 tachyzoites. All isolates were classified as virulent or intermediately virulent. Isolates were genotyped by means of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis, revealing three different genotypes. None of the isolates exhibited the clonal type I, II or III genotype. No genotypic differences were observed between the isolates from the brain or heart from the same bird.
