Abstract This study outlines the profile of research productivity grant holders of the Conselho Nacional de Desenvolvimento Científico e Tecnológico [CNPq (National Council for Scientific and Technological Development)] in the field of pediatric dentistry. A cross-sectional study with data collected from the Brazilian academic curriculum vitae database. The eligibility criterion was being a research productivity grant holder in pediatric dentistry from 2018 to 2020. In the period of interest, 215 individuals were research productivity grant holders in the field of dentistry, 33 of whom had graduate degrees (specialization, master's or doctorate) in pediatric dentistry. The period of scientific production and work concluded of advising of scientific initiation, master, doctoral and post-doctoral degrees was 2010 to 2020. Descriptive analysis was performed and the Kruskal-Wallis test was used to analyze associations (5% significance level) between productivity grant level (2, 1D, 1C, 1B or 1A) and year of obtainment of the doctoral degree. The VOSviewer (version 1.6.17) was used to present graphically the interinstitutional collaborations. The sample was composed of Level 2 researchers (66.7%), women (66.7%), researchers linked to institutions in the southeastern region of Brazil (81.8%), with a doctoral degree concluded prior to 2002 (51.5%), began working as a professor at a higher education institution prior to 2007 (78.8%) and the title of full professor (45.5%). No significant association was found between productivity grant level and year of conclusion of the doctoral degree (p = 0.10). Median (interquartile range) of scientific articles was 119 (37-312). The prevalence of citations (57.52%) and JCR articles (62.76%) was higher among female researchers. In conclusion, CNPq research productivity grant holders in pediatric dentistry are essentially represented by females from the southeast region of the country (UFMG and USP). However, males have proportionally greater productivity.

Abstract The longevity of prosthetic rehabilitation is determined by the stability of the implant and abutment interfaces. True morse taper connections on dental restorations have been effective, however activation force still empirical. This work compared the activation strength and internal contact of Morse taper system according to the removal force. Eighty sets, composed of implants and prosthetic abutments, were evaluated with different internal contact areas; 15.12mm2 (G3.3) and 21.25mm2 (G4.3). The specimens were activated at 0° and 30°, with loads of 10, 20, 40 and 60N. The specimens were submitted to tensile test and the data to ANOVA and Tukey’s tests (α=0.05). Representative specimens were examined under SEM. Removal force of G3.3 (2.15±1.33MPa) did not differed to G4.3 (1.99±1.03MPa). The activation at 0º (2.95±0.98MPa) statistically differed to 30º (1.19±0.54MPa). The 60N load was statistically superior for G3.3 and there was no statistical difference between 20N to 60N in G4.3. The values of 10N at 30o and 20N at the long axis of the morse taper implant, independent of the frictional contact area showed the best settlement.

Abstract A new device was developed to enable the visualization and measurement of canine angulation while at the same time visualizing and measuring the force transmitted to adjacent teeth. This study aimed to evaluate the mesiodistal tilt angle of the upper canine brackets, the wire deflection, and its effects on adjacent teeth with five different slot designs of upper canines. Wires (0.020” and 0.019” x 0.025”) were tested on different five bracket types at five different distal angles. The force applied to adjacent teeth was measured as the angle was increased, and its consequences were observed in the posterior and anterior regions as well. The force tension (gf) was measured in a universal testing machine. Data were submitted to a 3-way ANOVA and Tukey’s test (α=0.05). For both arches, regardless of the type of tooth and bracket type, the highest means tension mean values were shown by the 20° angle, followed by the 15°,10°, and 5° angles, which differed statistically among themselves. Overall, for 5°, 10°, and 15° angles, conventional and versatile brackets showed significantly higher force values in all teeth, tip-edge and control brackets showed the lowest. The highest force values were observed in central and lateral incisors with conventional and versatile brackets and on first and second premolar teeth with self-ligating passive and control brackets. Conventional brackets presented the highest forces, tip-edge and control brackets showed the lowest. The teeth that suffered the greatest forces were lateral incisors, and those that suffered the least were second premolars.

ABSTRACT: The bacteria Aeromonassp. are naturally reported in aquatic ecosystems and possess pathogenic potential, being considered as emerging pathogens in humans and animals. They also cause considerable losses in fish farming and, through water, can contaminate numerous foods. This study quantified and analyzed the antimicrobial resistance profile of Aeromonassp. in fish. A total of 72 samples of two fish varieties (leather fish, Pseudoplatystomafasciatumx Leiariusmarmoratusand round fish, Colossomamacropomumx Piaractusmesopotamicusand Colossomamacropomumx Piaractusbrachypomus) were purchased from two types of sources (fresh and frozen) and three commercial establishments (supermarket, market, and fishmonger). The 55 isolated Aeromonascultures were evaluated for their antimicrobial resistance profile by the disc diffusion method. Upon quantification, the count of Aeromonassp. ranged from 4.22 to 6.00 Log CFU/g; ten different species, including A. eucrenophila, A. hydrophila, A. caviae, A. media, A. jandaei, A. veroniibv. sobria, A. trota, A. schubertii, A. veroniibv. veronii, and A. shigelloides, were identified. Among the 55 isolates, 64.45% showed resistance to Ampicillin-sulbactam, and 75% were sensitive to gentamicin and ciprofloxacin. It was concluded that 100% of the evaluated samples were contaminated by Aeromonassp., which may present a risk to consumer health since bacteria can be etiological agents of Foodborne Diseases. The antimicrobial resistance profile showed resistance to ampicillin and multi-resistance to different classes of antimicrobials, demonstrating problems with choosing an antimicrobial for treatment of any disease.

ABSTRACT: Strawberries are of high social and economic importance and the crop is mainly produced at small family enterprises. Strawberries are repetitively amongst products in which unauthorized pesticide residues are determined. The PARA program launched in Brazil by ANVISA has disclosed that many samples have residues above the maximum residue limit (MRL). The present study appraised the pesticide residues detected in strawberries produced in the state of Rio Grande do Sul and marketed at the CEASA / RS. Along the harvesting seasons of 2018 and 2019, 62 strawberry samples were collected at the CEASA-pavilion destined for growers from the state of Rio Grande do Sul. Each sample was tested for 238 active ingredients of pesticides. Of the 62 samples retrieved, 40% were considered satisfactory and 60% resulted as unsatisfactory. Of the 25 satisfactory samples, three samples did not present any residues, and 22 had residues below the MRL. Of the 37 samples with an unsatisfactory outcome, 11 had active ingredients not allowed (NA) for use on strawberries, 13 presented active ingredients above the MRL and 13 reports presented the sum of both: residues above the MRL and NA. Thirty five different active ingredients were detected in the samples summing up to a total of 303 detection events. The active ingredients detected most frequently were procymidone (66.13%); carbendazim (53.22%) and difenoconazole (50%).

Authors: González-Galli Leonardo Martín , Pérez Gastón Mariano , Cupo Betina Ayelén , Alegre Cinthia Karen
Published: October 2022

Resumen En este trabajo se analiza el concepto de obstáculo epistemológico desde su origen en la obra de Gaston Bachelard hasta las distintas formas que adquirió en la didáctica de las ciencias naturales. A partir de dicho análisis se identifican algunos problemas teóricos, especialmente el uso demasiado amplio que se hace de la expresión 'obstáculo epistemológico', y se propone una definición que busca superar dichos problemas. A partir de dicha definición se sugiere como principal objetivo didáctico el desarrollo de una 'vigilancia metacognitiva' sobre los obstáculos epistemológicos. Luego se analiza la relación entre el concepto de obstáculo epistemológico y las nociones de concepción, modelo y sesgo cognitivo, concluyendo que ninguna de éstas puede reemplazar al primero. En las conclusiones se exponen las razones por las cuales el concepto de obstáculo epistemológico resulta de gran valor tanto para investigación en didáctica de las ciencias naturales como para la práctica de la enseñanza.

Authors: Yue Haixia
Published: October 2022

ABSTRACT Introduction: Dance sport is an emerging sport activity. The number of college students devoted to the study of dance is increasing. Basic dance sport skills are inherent to performance. Basic skills training requires dancers to have a certain degree of flexibility, endurance, speed, etc. Currently, we know that CORE strength training can improve the physical function of athletes, but studies are scarce as to its true impact on proprioceptive skills in dance sports. Objective: The purpose of this study was to examine the effect of strengthening the CORE on muscle coordination in sport dancers. This paper examines the relationship between core strength training and dance skills in athletes. Methods: Undergraduate sport dance students were randomly and voluntarily selected. These students undergo a 4-month training protocol in CORE strengthening. The effect of this experiment was evaluated with biomarker and kinetic data collected before and after the experiment. These data were worked out statistically and the results were discussed according to the literature. Results: After the CORE training protocol, the sport dance students had significant differences in physical tests(P<0.05). Conclusion: CORE training can promote physical stability, explosive power and muscle coordination in sport dancers. Level of evidence II; Training research - outcome investigation.

Abstract Panax vietnamensis Ha et Grushv. is a precious medicinal species native to the tropical forests of Vietnam. Due to habitat loss and over-harvesting, this species is endangered in Vietnam. To conserve the species, we investigated genetic variability and population structure using nine microsatellites for 148 individuals from seven populations across the current distribution range of P. vietnamensis in Vietnam. We determined a moderate genetic diversity within populations (HO = 0.367, HE = 0.437) and relatively low population differentiation (the Weir and Cockerham index of 0.172 and the Hedrick index of 0.254) and showed significant differentiation (P < 0.05), which suggested fragmented habitats, over-utilization and over-harvesting of P. vietnamensis. Different clustering methods revealed that individuals were grouped into two major clusters, which were associated with gene flow across the geographical range of P. vietnamensis. This study also detected that ginseng populations can have undergone a recent bottleneck. We recommend measures in future P. vietnamensis conservation and breeding programs.

Abstract Excessive use of insecticides has led to resistance of some pathogenic organisms (nematodes, bacteria and fungi), environmental contamination, and the presence of hazardous residues. Therefore, the aim of the present study was to evaluate synthetic metabolites derived from previous studies with edible mushrooms against the soybean weevil Rhyssomatus nigerrimus Fahraeus (Curculonidae) because of the relevance of pest control in an economically important crop. Furthermore, this is one of the first studies where edible fungal molecules are evaluated for the control of these insects. Initially, two in vitro tests (toxic effect and immersion) were evaluated against R. nigerrimus. In these tests, sensitivity and viability were determined in the 2% Tween control in water. For these two tests, the synthetic metabolites pentadecanoic acid (PNA), palmitic acid (PMA), stearic acid (STA), linoleic acid (LNA), β-sitosterol (βT) were evaluated individually as well as in combinations, “the fraction of standards (E1)”. Based on the results obtained, the dip test was selected to evaluate the mixtures of two standards (1. PMA + βT, 2. PMA + PNA, 3. PMA + LNA, 4. PMA + STA, 5. STA + βT, 6. STA + PNA, 7. STA + LNA, 8. PNA + βT, 9. PNA + LNA, 10. LNA + βT), three (1. PNA + βT + LNA, 2. PNA + βT + STA, 3. STA + LNA + PNA and 4. STA + LNA + βT) and four (PNA, βT, LNA and STA). The results showed that the mixture of three standards caused a higher percentage of mortality relative to the control group: l. PNA + βT + LNA and 2. PNA + βT + STA with 54.44 and 48% mortality of R. nigerrimus insects exposed for 15 days. These results show the importance of evaluating mixtures of molecules against R. nigerrimus.

Abstract The Hooded Gnateater Conopophaga roberti Hellmayr, 1905 is an insectivorous understory passeriform with discrete behavior, whose reproductive attributes are poorly-known. In the present study, we describe the reproductive biology of the species and the growth pattern of the nestlings, based on observations conducted in remnants of the Cerrado savanna in eastern Maranhão state, in Brazil. The nests were identified during active searches conducted between June, 2018 and March, 2021. A total of 22 nests were found over the course of three breeding seasons. The cup-shaped nests were supported by small branches and were constructed at a mean height of 40.6 ± 16.1 cm (N = 21) above the ground. The nests were 23.1 ± 3.9 cm in length and 14.1 ± 1.6 cm in width (N = 21). The eggs were beige in color, with irregular brown mottling only at the rounded end of the egg, which had a mean length of 21.3 ± 0.8 mm, width of 17.2 ± 0.8 mm, and mass of 3.1 ± 0.1 g (N = 23). Hatchlings are completely naked and weigh 3.1 ± 0.2 g (N = 7), and when they abandon the nest, they have yet to reach full adult size, with the total length being 65.4% of that of the adult, the wing, 65.4%, the head, 73.9%, the culmen, 74.2%, the body mass, 73.3%, and the tarsus, 89.0% that of the adult. The growth curves are sigmoidal and all the coefficients of determination are at least 0.96, with the body length having the highest value (R2 = 0.98). During the breeding season, the adult pair emitted alarm calls constantly when observers were in the vicinity of the nest. On a number of occasions, members of the breeding pair were observed moving away from the nest as it was approached by observers, while engaging in broken-wing display. The nest architecture, the color of the eggs, and the behaviors presented by this gnateater were similar to those described for other Conopophaga. With this work we contributed to improve the knowledge on the breeding behavior of this poorly know group of understory insectivorous birds.
A área cultural das terras baixas da América do Sul: por uma definição estrutural

Resumo Este artigo, originalmente escrito em 1973 e publicado aqui pela primeira vez, propõe que, a despeito de sua evidente variedade cultural, as sociedades indígenas das terras baixas da América do Sul compartilham uma característica estrutural invariante que as define como “área cultural”. Esta característica é a sua terminologia de relacionamento em duas linhas articulada pela troca direta. Uma análise de terminologias de uma ampla gama de sociedades da região revela tal característica invariante apesar das diferenças terminológicas. O artigo é precedido por uma curta nota introdutória escrita especificamente para a publicação.
Entre a distração e o esquecimento: a colonização da fronteira Brasil-Guiana segundo leituras históricas e míticas
Authors: Amaral Virgínia
Published: October 2022

Resumo: No livro Absent-minded Imperialism, o antropólogo Peter Rivière reconstitui o litígio do Pirara, que definiu a fronteira entre o Brasil e a Guiana Britânica de então. Em contraste com as percepções de colonizadores ingleses, manifestas nas fontes privilegiadas pelo autor, este artigo examina leituras dos povos Kapon e Pemon de aspectos da colonização da Guiana, os quais também se revelaram em episódios específicos do litígio. Essas leituras são inerentes a narrativas míticas de origem da religião Areruya - uma cristalização de antigos movimentos proféticos kapon e pemon. Muitos deles foram liderados por pajés, que conviveram periodicamente com missionários cristãos. Hoje, os adeptos da religião indígena negam que ela tenha influência missionária. Para refletir sobre essa percepção, considero tanto o que as próprias narrativas míticas relativas obliteram quanto o que elas preservam da história do contato dos profetas pioneiros com missionários. Por fim, sugiro que a versão mais claramente mitificada condiz melhor com o lugar na colonização no sistema conceitual de Areruya.

ABSTRACT: Histomonas meleagridis and Tetratrichomonas gallinarum are two protozoans responsible for mortality associated with typhlohepatitis in poultry. In this study, the etiology of high mortality in Chukar partridges suspected of infection with these agents was investigated pathologically and molecularly. Twelve healthy partridges during the laying period and 30 partridges that died due to disease and were included in the study. In blood analysis, increased levels of WBC, NEU, LYM, MONO, EO and BASO suggesting bacterial and/or parasitic infection; decreased levels of HGB, MCH and MCHC, which are markers of anemia; and increased AST and LDH levels, which are important for liver degenerations. In the liver, which is one of the most pathologically affected organs, multifocal necrosis foci that sometimes merge with each other and spread to large areas, and severe fibrino-necrotic typhlitis were detected. There was amyloid deposition in the space of Disse and vascular sinuses in the liver. PAS positive protozoal agents were observed in and around the lesioned areas. By PCR analyzes using specific primers, 11 of the samples were positive for H. meleagridis only, whereas 5 were positive for T. gallinarum only; 14 samples tested positive for both agents. Sequence analysis showed 100% identity between all samples resulting in positive PCR. In addition, Escherichia coli was produced in microbiological culture (27 of 30). When all the results were evaluated together, it was concluded that H. meleagridis and T. gallinarum and secondary E. coli may cause high mortality in partridges under lay stress.
Delegitimization strategies as a means of policing protesters online during the pandemic in Poland
Authors: Rak Joanna
Published: October 2022

ABSTRACT Introduction: This paper identifies delegitimization strategies that illustrate a range of attitudes of the Polish police towards individuals who resist the government and challenge the state legitimacy. Materials and Methods: The research is embedded in the theories of macro-strategies of delegitimization, out-casting micro-strategies, and is based on qualitative intertextual analysis of police statements in order to explain how the police responded to social opposition and shaped their relations with protesters during the pandemic periods. The study covers the following data: entries on official websites, statements to the public broadcaster TVP Info, and tweets released by the Polish Police Headquarters and the Warsaw Police Headquarters. Results: At the macro-strategy level, the research illuminates the online dimension of the protesters’ discipline process, as well as the policing of protests based on out-casting. These are the predominant resources of delegitimization of the cause. It is argued that its use was based on the categorization of protesters as violators of both law and social norms. In turn, the main micro-strategy applied within out-casting was criminalization formulated in reference to COVID-related law. Delegitimization strategies revealed the nature of moral justifications for negative attitudes towards protesters, as well as threats from and effective use of force. They also allowed the police to legitimize themselves in the public eye and to place their roles as protectors of human life, health, property, public security and order. Discussion: Unconditional acceptance and enforcement of the unconstitutional law established by the government revealed the political bias of the police. The delegitimization of the participants of the anti-government protests and the active and unquestionable acceptance of the pro-government demonstrations confirmed their political favoritism.

Published: October 2022

Considerando que para o ensino de física no Ensino Médio adota-se, geralmente, nas escolas públicas o livro didático aprovado pelo Programa Nacional do Livro e Material Didático (PNLD) e que esse pode ser o único referencial para professores e estudantes, ocorreu-nos a seguinte questão: o livro didático pode efetivamente assumir esse protagonismo quando se trata do ensino da Física de Partículas Elementares? Para respondê-la, analisamos as resenhas contidas no Guia dos Livros Didáticos do PNLD de 2018 e 2021 utilizando a técnica de análise de conteúdo. Complementar a isso, identificamos quais conceitos são apresentados nos livros que são objetos de conhecimento para a Física de Partículas Elementares (ou Modelo Padrão), porque a depender da experiência/interesse do professor e do livro didático esse tema poderá ser negligenciado em sala de aula. Os resultados da análise de conteúdo evidenciam características que permeiam um livro na condição de material instrucional didático, tais como: metodologia de ensino e conhecimento didático-pedagógico. Os objetos de conhecimento relacionados a Física de Partículas Elementares foram identificados nos livros a partir de um rol de perguntas de caráter dicotômico.

ABSTRACT The problem addressed is the contamination of the Yarinacocha Lagoon water by heavy metals and poor use of agricultural residues. It was manufactured activated carbon from cocoa (Theobroma cacao L.) pod husks and determined its adsorbent effect in removing polluting metals from the waters of the Yarinacocha Lagoon. The response surface methodology was applied with factorial designs 33 and 32, with three replicates to optimize obtaining the adsorbent and measure its effectiveness in metal removal. The modeling of the pyrolysis process resulted in 17.27 g of activated carbon from 295.72 g of dry pod husks, optimal with the following optimal parameters: 150 °C as activation temperature, 450 °C as carbonization temperature, and 2.5 hours as modification time. This resulted in effective removal of pollutant metals (aluminum: 91.43%, copper: 75%, iron: 58.33% and zinc: 58.33%), from waters samples demonstrating that it is possible to manufacture activated carbon from cocoa pod husks, with an adsorbent potential to remove metals from the waters of the Yarinacocha Lagoon.

ABSTRACT Adequate mineral supplementation can be a strategy to enable the use of brackish water in the production of vegetables. This study intended to evaluate the effect of calcium nitrate concentrations on leaf gas exchanges and yield of kale (Brassica oleracea L) fertigated with salinized nutrient solutions. The experiment was conducted in a randomized block experimental design (4 + 1), with four replicates. Four nutrient solutions prepared in brackish water (6.0 dS m-1) containing four concentrations of Ca(NO3)2 [(750, 1,125, 1,500, and 1,875 mg L-1)] and a control treatment (standard nutrient solution using low-salinity water, 0.5 dS m-1 (750 mg L-1 of Ca(NO3)2) were used in the study. The following analyses were performed: leaf gas exchanges, leaf area, and fresh matter yield. The standard nutrient solution promoted higher values for photosynthetic rate (13.06 µmol CO2 m-2 s-1), stomatal conductance (0.19 mol H2O m-2 s-1), transpiration (2.76 mmol H2O m-2 s-1), instantaneous water use efficiency (4.73 mmol CO2 mol-1 H2O), instantaneous carboxylation efficiency (0.053 mmol CO2 mol-1 CO2), leaf area (2.78 cm2 per plant), and leaf fresh matter yield (2.64 kg per plant). The Ca(NO3)2 not nullified but mitigated the deleterious effect of salt stress on leaf gas exchanges, except for kale yield (leaf fresh matter).

Published: October 2022

Abstract The present paper distinguishes how the type of bank that provides loans is related to GDP per capita in Brazilian municipalities between 2007 and 2016. A unique data set allows us to discriminate between the effects of credits operated by either private or public commercial banks, and loans provided by the national development bank BNDES either directly or indirectly through accredited financial institutions. Using the system GMM estimator, we find that credit from public commercial banks has the highest effect on economic growth but it is concentrated in the most populated municipalities. Moreover, indirect BNDES loans show a robust and significantly positive relation to local GDP given that this lending facility especially targets firms in small, credit constrained regions, and it was provided non-cyclically.

ABSTRACT Objective: To analyze the trend of mortality from falls among older adults in Brazil from 2000 to 2019. Methods: This is an epidemiological, analytical study with an ecological time-series design. A retrospective analysis was performed using secondary health data extracted from the Brazilian Mortality Information System in the specific period. Standardized rates of general and sex- and age-specific mortality were calculated. To observe the mortality trend, the Prais-Winsten model and the Annual Increase Rate (AIR) were used. Results: We identified 135,209 deaths resulting from falls in older adults in the period from 2000 to 2019. Mortality from falls in general, during the study period, had an upward trend (β=0.023; p<0.001; AIR=5.45%). We observed that both men (β=0.022; p<0.001; AIR=5.19%) and women (β=0.024; p<0.001; AIR=5.72%) had an upward trend. Regarding age group, the results also pointed to an upward mortality trend in all age strata, although higher in older people aged ≥80 years (β=0.027; p<0.001; AIR=6.38%). Conclusion: There was an upward trend in mortality rates in Brazil during the time series studied. These findings suggest the importance of defining a line of care for this age group, focusing on promoting health in older adults and preventing the risk of falls, aiming at a reduction in the number of deaths from this cause and favoring the quality of life of this population.

Abstract: Introduction: Services aimed at psychosocial care are essential for guaranteeing the rights of the assisted population, acquiring a long process, and still current, called Psychiatric Reform, with a public policy design of strategies and programs for the effectiveness of care aimed at the individual and their social context. Among these, embracement stands out as an interlocutor in the processes that involve the user of the Psychosocial Care Network and the services provided by the health units, with emphasis on the Psychosocial Care Center and in particular care related to alcohol and drug users (CAPSad). The present experience report aims to present the nuances of embracement present in the services and activities provided by a CAPSad in a municipality in the interior of Bahia and the importance of this experience for medical training. Experience report: the experiences were presented in four moments: first contacts and the experience of getting to know the CAPSad; Symposium on the care of users of alcohol and other drugs, monitoring medical consultations in mental health and carrying out activities in the waiting room and with therapeutic groups. Discussion: The experiences of comprehensive mental health care enabled the medical student to experience embracement and the singularities of psychosocial care; understand the vulnerabilities of people who use alcohol and illicit drugs; the importance of the family in the care process; participate in medical consultations based on the Person-Centered Clinical Method; as well as multiprofessional care for the integrality of health actions. Conclusion: Comprehensive mental health care constitutes a challenging and necessary topic for the training of the future physician. The inclusion of the student in the psychosocial care network favors the processes aimed at teaching-learning and strengthens the teaching-service-community integration.

Abstract Functional enzyme assays to detect sublethal poisoning of Neotropical fish are paramount. Accordingly, we assayed a glutathione S-transferase (GST) activity in liver and kidney cytosols from Piaractus mesopotamicus injected with methyl parathion or benzo[a]pyrene using the substrate 1-chloro-2,4-dinitrobenzene (CDNB), which is the usual substrate for assaying a known general activity of GST. Since the most reactive substrate is required to reveal specific changes in enzyme activity, we also used two alternative substrates, 1,2-dichloro-4-nitrobenzene (DCNB) and ethacrynic acid (ETHA). Activities with CDNB or ETHA did not change. However, assays with DCNB showed that methyl parathion caused a decrease in GST activity in the liver on the 24th, 48th and 96th hour after the injection. DCNB also revealed that GST activity in the liver increased seven days after benzo[a]pyrene injection, coming down to normal after fourteen days. Benzo[a]pyrene, but not methyl parathion, increased the activities with DCNB in cytosol from the kidney seven and fourteen days after the injection. Thus, a decreased liver GST activity assayed with DCNB corresponded to contamination of P. mesopotamicus with methyl parathion. The increase of this GST activity in the liver and the kidney correlates to pacu contamination with polycyclic aromatic hydrocarbons.
Notes for life: a Henrian research methodology in psychology
Authors: CASTRO Gillianno José Mazzetto de
Published: October 2022

Abstract This study aims to consider a Henrian methodology in Psychology. It is a theoretical, cross-sectional study that, drawing on the phenomenological tradition in Psychology, seeks to structure a research itinerary in two dimensions or layers of appearance. 1st – the intentional classical phenomenology display, and 2nd – the essence of the Henrian phenomenology manifestation. This route follows phases ranging from the design of the research and the constitution of the phenomenological view, reaching the synthesis scenario in which researchers can draw their conclusions about the content of the experience investigated. The insertion of the essence dimension manifestation enriches the traditional phenomenological method, opening up to Psychology the possibility of exploring the pathos avec. It provides Psychology with a methodological route to understand the dynamics of human experience beyond the health-disease model. It is necessary to continue the research in view of the development of the measurement instruments.
