title: Exploring online oral health misinformation: a content analysis

description: Abstract Considering the unfavorable implications of health falsehoods and the lack of dental research into information disorder, this study aimed to identify and characterize online oral health misinformation. A total of 410 websites published in English were retrieved using Google Advanced Search and screened by two independent investigators to compile falsehoods through thematic content analysis. Afterward, 318 pieces of misinformation were consensually divided into four groups concerning their informational interest (G1), financial, psychological, and social interests produced/disseminated by non-dental professionals (G2) or by dental professionals (G3), and political interests (G4). Social media (Facebook and Instagram) and fact-checking tool (Snopes) were also screened to determine the spread of falsehoods by identifying corresponding posts and warnings. As a result, misinformation was mainly associated with gum diseases (12.0%), root canal treatment (11.6%), toothache (10.4%), fluoride (10.4%), and dental caries (9.8%), with a special highlight on recommendations for the usage of natural products, toxicity concerns, and anti-fluoridation propaganda. Additionally, most misinformation was allocated in G3 (41.9%), which presented a statistically higher frequency of financial interests than G4. Finally, falsehoods were considerably identified on Facebook (62.9%) and Instagram (49.4%), especially G3 and G4. Nevertheless, Snopes has debunked only 5.9% of these content items. Therefore, misinformation was predominantly produced or disseminated by dental professionals mainly motivated by financial interests and usually linked to alternative/natural treatments. Although these items were shared on social media, fact-checking agencies seemed to have limited knowledge about their dissemination.

title: COPING IN SOCCER ATHLETES: A SYSTEMATIC REVIEW

description: ABSTRACT Objective: Review the studies that investigated coping in soccer. Methods: A systemic search was carried out in the following databases: Pubmed, Web of Science, Scielo, Scopus, PsychINFO and SPORTDiscus. The descriptors related to the terms (Coping skills, Sport and Football) were verified in the MeSH (Medical Subject Headings) database. The inclusion criteria used were: Empirical studies published in journals peer-reviewed scientific papers; b) Studies published from December 2014 to December 2019; c) with at least one quantitative measure; d) Studies with samples of soccer athletes; and e) Articles with specific reference to the topic 'Coping skills'. Results: The results showed that coping skills interact with important variables for good performance in elite soccer, such as competitive level, sports talent, psychopathologies, age group and sex. More specifically, it was noted that the development of some coping strategies, such as facing adversity, trust/motivation and performance under pressure, are potentially common to these variables. Conclusion: It is concluded that the development of some coping strategies is fundamental to the elite athlete, since it is positively associated with the optimal development of most of the variables analyzed in the synthesized studies.

title: Bentonite as an additive in the composting of wastewater sludge from the poultry agroindustry

description: Abstract The objective of this work was to evaluate the use of bentonite as an additive in the composting of wastewater sludge from the poultry agroindustry regarding nitrogen conservation, carbon degradation, and nutrient content increase. The experimental design was completely randomized with five treatments with bentonite at 0, 0.5, 1.0, 3.0, and 6.0%, with three replicates. The organic compost used in the treatments consisted of pine sawdust and wastewater sludge from the treatment plant. During and after the composting process, the following were analyzed, respectively: pH, dry matter, temperature, and C, N, NH4+, NO2-, and NO3- contents; and P, K, Ca, Mg, Cu, and Zn contents and humic and fulvic acid concentrations. Bentonite at 6.0% increased C degradation, N losses, Mg content, and humification, but decreased Zn content and humidity. Bentonite, as an additive in the composting of sludge from the poultry agroindustry, promotes humification, decreases Zn content and humidity, but does not affect pH and P, K, Cu, NH4+, NO2-, and NO3- contents.

title: Analysis of variables inherent to the dynamics of the practice of vaquejada to determine its influence on the result obtained in the competition

description: Abstract The objective of this work was to evaluate several attempts to knock down neats and to correlate the success obtained with actions performed by the horse/rider sets through an analysis of public domain videos of vaquejadas. Approximately 300 videos were considered, and the groups were evaluated according to the competition category, that is, amateur/aspirant and professional, and the animals used in the test, that is, pulling or tracking of the neat. It was found that for the pull set in the professional competition category, only the characteristics of directing the cow on the track, and the guiding behavior and positioning in the pull were significant (p&lt;0.01), while for the amateur/aspirant category, the characteristics of remaining in the pull after falling of the cattle and of the behavior at the gate had an effect (p&lt;0.01). The characteristic of remaining in the pull after the fall of the neats, in the category of professional pulling athletes, exists in greater prevalence during the competition with 85.3%, while the characteristic of directing the neat to the side of the track is performed by 87.6% of the competitors. For the set used to track the cattle, the values of the dimensions 1 and 2 were 96.56% and 3.43%, respectively, which is 99.9% of the total variance of the data based on those selected for the final result of “earn the ox”. The use of multiple diversity analysis in this study of variables associated with the vaquejada set proved to be quite advantageous, and there was not much variation in the elements obtained with a greater weight in the determination of the final result.

title: Genetic gain in Passiflora seed traits from recurrent selection among full-sib families

description: Abstract The germination potential must be considered in the selection of passion fruit genotypes, since vigorous seeds originate seedlings with a higher growth rate, resulting in superior plants with high agronomic performance. This study proposes to estimate genetic parameters and selection gain for seed traits of full-sib families (FSF) of passion fruit under recurrent selection for resistance to the cowpea aphid-borne mosaic virus (CABMV). Physical and physiological seed traits of 86 FSF were evaluated; genetic parameters, genotypic correlations between traits and genetic gains were estimated using four selection indices. There were significant differences and genetic variability between families and positive genetic correlations between variables. The best distribution of genetic gains was obtained by the Mulamba and Mock index, using the heritability coefficient and arbitrary weights. This index selected the best 26 families in terms of seed characteristics to compose the second cycle of recurrent selection for resistance to CABMV.

title: Aromaticity of aza aromatic molecules: prediction from Hückel theory with modified parameters

description: Hückel theory is a simple and powerful method for predicting the molecular orbital and the energy of conjugated molecules. However, the presence of nitrogen atoms in aza aromatic molecules alters the Coulomb and resonance integrals owing to the difference in electronegativity between nitrogen and carbon atoms. In this study, we focus on acridine and phenazine. Further correction is implemented based on the ring current model, thus revealing the change in resonance integral for the carbon-carbon bond along the bridge of the molecule. The Hamiltonian of the π-electron system in the Hückel method is solved using the HuLiS software. Various geometry-based aromaticity indices are used to obtain the aromaticity indices of the two non-equivalent rings. For further evaluation, the results for bond lengths are used to calculate the associated bond energy. Considering the carbon-hydrogen (CH) bonds, the total molecular energy is compared with the experimental heats of formation for a number of benzenoid hydrocarbons and aza aromatics, in addition to the two studied molecules. Finally, the correlation between the nitrogen atom on the aromaticity index and the ring energy content is evaluated to determine to which extent the Hückel model agrees with previous experimental and advanced computational studies.

title: Effect of dietary protein:lipid ratio on growth and body composition in bullfrog (Lithobates catesbeianus)

description: ABSTRACT A feeding trial was performed to assess dietary protein:lipid ratios for the grow-out phase of the bullfrog (Lithobates catesbeianus). Nine balanced isoenergetic diets were formulated, combining three different protein levels (300, 400, and 500 g kg−1) with three different lipid levels (50, 100, and 200 g kg−1), designated as P300/50L, P300/100L, P300/200L, P400/50L, P400/100L, P400/200L, P500/50L, P500/100L, and P500/200L. Additionally, a commercial fish feed, commonly used in Mexico to feed bullfrogs, was also tested during the experiment. Growth performance, animal performance parameters, carcass composition, and fatty acid profiles in muscle and liver were evaluated. The feeding trial results showed that all the experimental diets enhanced growth, feed conversion ratio, and frog-leg weight compared with the commercial diet. Bullfrogs had higher growth with 400 and 500 g kg−1 of dietary protein regardless of dietary lipid content. It was also notable that with the P500/200L diet, frogs doubled the weight of those fed the commercial diet. DHA, EPA, and total omega-3 fatty acids were double in muscle and two to eight times higher in the liver compared with the commercial diet. In all cases, the final proximal composition of carcass reflected the diet composition. It is suggested that a diet containing 400 g kg−1 of protein and 50 g kg−1 lipids (protein/lipid ratio: 7.4; gross energy: 18.2 MJ kg−1) is adequate for bullfrog performance during the grow-out phase to achieve market size in a shorter period, thus, reducing farming risks and production costs.

title: Assessment of the cytogenetics and leaf anatomy of synthetic polyploids of Eucalyptus clones

description: Abstract The induction of polyploidy in Eucalyptus can lead to higher-yielding and more adapted clones, with better wood quality. After artificial polyploidization, it is necessary to certify the effectiveness of the process through cytogenetic analyses and anatomical trait evaluations. Thus, the aim of this study was to certify the chromosome duplication in artificially polyploidized clones of Eucalyptus grandis × Eucalyptus urophylla using cytogenetic analysis, flow cytometry, and leaf anatomy measurements. Chromosomal counts and DNA content estimation allowed the identification of artificially polyploidized clones and mixoploids. Polyploid clones had larger stomata diameter than diploids. The increase in stomata size was accompanied by lower stomatal density in most polyploid clones. The typical gigas effect of polyploidized plants was demonstrated by the expressive increase in leaf area in polyploid individuals compared to diploids. Our findings indicate that the use of polyploidy in Eucalyptus breeding is promising, allowing the discrimination of diploid, tetraploid, and mixoploid plants.
