title: Comparative toxicity of essential oil and blends of selected terpenes of Ocotea species from Pernambuco, Brazil, against Tetranychus urticae Koch

description: ABSTRACT Essential oils from the leaves of two species of the genus Ocotea that occur in the Atlantic Forest in the state of Pernambuco, Brazil, were analyzed using gas chromatography-mass spectrometry. The acaricidal activity of these oils as well as 11 selected components and blends were evaluated in fumigation and residual contact tests against the two-spotted spider mite (Tetranychus urticae). Sixty-seven constituents were identified, totaling 97.3 ± 0.3% and 97.8 ± 0.5% of the oils from O. duckei and O. glomerata, respectively. Sesquiterpene was the dominant class. The compounds β-caryophyllene (18.6 ± 0.1%) and aromadendrene (17.3 ± 0.6%) were the main constituents of the oils from O. duckei and O. glomerata, respectively. Acaricidal action varied depending on the method employed, species and chemical nature of the selected constituents. The mites were susceptible to the oils and chemical constituents using the fumigation method. The O. duckei oil was respectively 2.5-fold and 1.5-fold more toxic than the O. glomerata oil using the fumigation and residual contact methods. Among the selected constituents, β-caryophyllene was the most toxic, independently of the method employed. The individual toxicity of the selected compounds and their blends as well as the role of these constituents in the overall toxicity of the essential oils are also discussed.

title: Comparison of physical and chemical composition of three chinese jujube (Ziziphus jujuba Mill.) cultivars cultivated in four districts of Xinjiang region in China

description: Abstract This study investigated the physical and chemical composition of three jujube fruits cultivated in China. The objective was to explore the effect of jujube genotype and cultivation districts on the quality of jujube fruits. Results showed significant differences on their physical and chemical composition. The Junzao cultivar contained relatively low level on the total dietary fiber, protein, total sugar, and total titratable acids. The Huizao cultivar possessed the mediate level of the sugar-to-acid ratio and ascorbic acid. The Dazao cultivar showed high level of the total dietary fiber, protein, sugar, and total acids. The cultivation districts exerted important roles in altering the physicochemical indexes of the same jujube cultivar. The Junzao cultivar harvested in the Hami and Kashi districts showed the significant difference on the level of the sugar-to-acid ratio and ascorbic acid compared with that in the Akesu and Hetian districts. The Huizao cultivar in the Kashi area possessed higher content of the total soluble dietary fiber than that in the Akesu and Hetain districts. Principal component analysis indicated that the parameters that differentiated these jujube cultivars appeared to be the total dietary fiber, protein, total sugar, fructose, glucose, sucrose, and total titratable acids.

title: Reparative Dentin Formation Using Stem Cell Therapy versus Calcium Hydroxide in Direct Pulp Capping: An Animal Study

description: Abstract Direct pulp capping process is a therapeutic method aimed at maintenance of pulp vitality and health by using a biocompatible material placed directly over the exposed pulp. The aim of this study was to evaluate and compare the effect of direct pulp capping procedures by dental pulp stem cells (DPSCs) or calcium hydroxide on dentin tissue formation. Three mongrel dogs were used as experimental model. Two access cavities were prepared in the right and left mandibular fourth premolars in all dogs to expose and extirpate the pulp tissues which were processed in the lab to obtain a single-cell suspensions. The isolated cells were cultures in odontogenic medium for subsequent differentiation. The maxillary teeth (3 incisors and one canine) of the corresponding dog number were subjected to class V cavities to expose their pulps which were assigned into 2 groups of 12 teeth each ( group I - pulp capping with calcium hydroxide) and (group II - pulp capping with dental stem cells DPSCs). The operated teeth were collected after 3 months and processed for histological and electron microscopic examinations. Specimens were subjected to elemental analysis of calcium and phosphorus. EDX elemental analysis revealed significant differences in the calcium and phosphorous wt, % in the reparative dentin of calcium hydroxide treated group which confirmed histologically. Direct pulp capping by DPSCs has shown promising generative potential for regaining normal dentin.

title: Low frequency of antibodies anti-Neospora caninum in rodents in Fernando de Noronha Island, Brazil

description: Abstract This study aimed to evaluate the frequency of Neospora caninum antibodies in rodents from the Island of Fernando de Noronha, Brazil, and to contribute to epidemiological data on neosporosis in this region. Blood samples were collected from 154 black-rats (Rattus rattus) and 12 rock-cavies (Kerodon rupestris). The search for anti-N. caninum antibodies was made using the NAT technique, with a cut-off of 1:20. The frequency of positive mice was 5.19% (8/154 - 1:20 titer) and all rock-cavies were negative. The low frequency of antibodies against N. caninum in rodents found in the Island shows the low contamination of the environment where these animals live.

title: High-Lard and High-Cholesterol Diet, but not High-Lard Diet, Leads to Metabolic Disorders in a Modified Dyslipidemia Model

description: Abstract Background: In view of the increased global prevalence of cardiovascular and hepatic diseases, the diet lipid content and its relationship with the accumulation of fat in hepatocytes have been investigated as key factors in preventing these diseases. Objective: To evaluate the metabolic effects of a high-lard diet supplemented or not with cholesterol on a modified dyslipidemia model. Methods: We divided 24 adult male Wistar rats into three groups: standard diet (STD - 4% lipids), high-lard diet (HLD - 21% lard), and high-lard and high-cholesterol diet (HL/HCD - 20% lard, 1% cholesterol, 0.1% cholic acid). After six weeks of treatment, blood and liver were collected for biochemical (serum lipid profile and liver enzymes) and morphological analyses. Statistical analysis included one-way analysis of variance (ANOVA), followed by Tukey test for mean comparisons, and a 5% probability was considered statistically significant. Results: Animals fed HL/HCD showed increased total cholesterol, triacylglycerol, LDL-c, non-HDL-c, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) serum levels compared to those fed STD. In addition, the HL/HCD animals presented higher relative liver weight, with moderate macrovesicular hepatic steatosis and inflammatory infiltrate. Conclusion: A high-fat diet with lard (20%) and cholesterol (1%) triggered dyslipidemia with severe liver damage in rats in a shorter experimental time than the previously reported models. The high-lard diet without supplementation of cholesterol led to body weight gain, but not to dyslipidemia.

title: Contributions to a Psychoanalytic Theory of Perception: The Hallucinatory Regression to the Thing Of Desire

description: Abstract: This article seeks to examine the relationships between perception, psychic reality, and desire from the perspective of Freudian psychoanalysis. In the first part of the study, the "scheme" of the psychic apparatus proposed by Freud in The Interpretation of Dreams (1900), presenting the mechanism of hallucinatory regression, was demonstrated as revealing the temporal structure of desire, within which the problem of perception receives an actual psychoanalytic sense. In the second part, the emergence of the notion of das Ding (the Thing), already present in Project for a scientific psychology (1895), is observed, indicating that the field of perceptual phenomena is articulated in terms of the relationship of the subject to the "fellow human being" (Nebensmensch), and, thus, to the Thing of desire, in addressing the constituent helplessness of psychic life.

title: Stability of a dairy-based electrolyte replenishment beverage

description: Abstract This study targeted the commercial sterility and shelf life evaluation of an isotonic beverage formulated with ricotta cheese whey (scotta). The beverage was processed at 95 °C/50 s (B1), 90 °C/40 s (B2) and 85 °C/30 s (B3), all stored at 25 °C in the dark. Commercial sterility tests were carried out to evaluate the microbiological stability of the product. Hedonic scale tests were performed to estimate the beverage´s shelf life. Average scores greater than 5 (in a 9-point hedonic scale) and percentage of approval greater than 60% were both used as threshold values for evaluating the overall acceptance of the product. The pH values, titratable acidity and soluble solids were determined at the beginning and the end of the shelf life study. The pH values ranged from 2.97 to 3.21, titratable acidity from 0.358 to 0.464 g citric acid/100 mL and soluble solids from 6.35 to 6.40 °Brix. All batches achieved the commercial sterility and had their shelf lives limited by the decrease of the sensory acceptability of the beverage, estimated in 100 (B1), 128 (B2) and 153 (B3) days. The milder binomial provided the longer shelf life, compatible with an eventual demand of the consumer market.

title: Serological detection and risk factors for equine piroplasmosis in the semiarid region of Pernambuco, Northeastern Brazil

description: Abstract Equine piroplasmosis, an economically important disease in horses, has so far not been reported in Pernambuco state, Brazil. This study aimed to evaluate the seroprevalence of anti-Babesia caballi and anti-Theileria equi antibodies based on the detection of these agents in equine blood and in ticks on horses in the municipality of Petrolina, Pernambuco, northeastern Brazil. Blood samples were drawn from 393 horses and sera were examined by ELISA. The presence of tick infestations was evaluated, and 101 ticks were subjected to DNA amplification for the detection of Babesia spp. by polymerase chain reaction (PCR). No parasites were detected in the blood smears. Anti-B. caballi and anti-T. equi antibodies were found in 27.2% (107/393) and 34.8% (137/393) horses, respectively. Infestation by Dermacentor nitens was detected in 4.3% (17/393) of the horses. There was no DNA amplification of the agents in ticks. The risk factors for the presence of anti-T. equi antibodies (P &lt; 0.05) were: purebred (P &lt; 0.001), animals older than 156 months (P = 0.014), and the presence of ticks (P = 0.001). No risk factors for B. caballi were identified. This study confirmed the circulation of agents of equine piroplasmosis in the municipality of Petrolina, state of Pernambuco, Brazil.

title: Meta-analysis about knowledge to teaching fractions division

description: Abstract The aim of this article is to identify the main contributions of studies on teaching knowledge regarding the teaching and learning and to analyze how these results contribute to answering the question: which set of knowledge does a teacher need to teach and learn for fraction division? We performed a qualitative metaanalysis on this theme (considering both the mathematical and didactic-pedagogical dimension) through successive readings and content analysis of a corpus of 58 studies all resulting from the search in six databases (JSTOR, ERIC, CAPES Theses Bank, SciELO, Mathematics Teacher's Journal Database and Google Scholar). The results obtained provided the integrative vision of a set of knowledge involved in five large blocks, namely: 1. Definitions and notations; 2. Algorithms, their justifications and other procedures; 3. Interpretations and associated problems; 4. Instructional explanations, teaching proposals and didactic resources; 5. Aspects of student learning. We conclude the article by explaining the usefulness of this set of specialized knowledge to teach fraction division for graduates, teachers, trainers, and researchers, as well as their importance for improvement in the mathematic education and for the appreciation of the teaching profession.

title: Effect of Competitive Anxiety on Decision-Making in Young Volleyball Athletes

description: Abstract The aim of this study was to analyze the effect of competitive anxiety on decision-make of young volleyball athletes. The sample was composed of 24 volunteers. We used the Competitive State Anxiety Inventory (CSAI-2R) to evaluate the competitive anxiety. Decision-making was evaluated in real game situation, adopting the criteria of Game Performance Assessment Instrument (GPAI). Negative correlations were found between the decision-making index and both cognitive anxiety and somatic anxiety (p&lt;0.05). In contrast, positive correlation was revealed between self-confidence and the decision-making index (p&lt;0.05). The findings revealed the influence of cognitive anxiety, somatic anxiety and self-confidence in the decision-making index (p&lt;0.05). It was concluded that anxiety can be considered an intervening factor in decision-making of young male volleyball players.
