ABSTRACT

Levels of 237 pesticides were assessed in 1063 fruit and vegetable samples from 12 São Paulo markets spanning the period May 2015 to December 2022. The QuEChERS method was employed for extraction, followed by GC-MS/MS and LC-MS/MS analysis. Findings indicated that 30% of the samples contained residues below the Maximum Residue Limits (MRLs), while 6% exceeded these. Additionally, 23% exhibited excessive residues for their respective crops and 40% had no detectable residues. Health risk evaluation focused on tomatoes, cabbage and oranges, revealing exposure within 0.002-0.9% of the Acceptable Daily Intake (ADI), indicating no chronic risks. However, pyraclostrobin in orange presented a potential acute risk for adults (112%). These results underscore the necessity for continuous monitoring of pesticide residues in fruits and vegetables to safeguard consumer health, especially considering the significant levels of consumption.

ABSTRACT

This study aimed to describe a support material removal protocol (SMRP) from inside the root canals of three-dimensional printed teeth (3DPT) obtained by the microcomputed tomography (microCT) of a natural tooth (NT), evaluate its effectiveness by comparing the 3DPT to NT in terms of internal anatomy and behaviour toward endodontic preparation, and evaluate if 3DPT are adequate to assess the differences between two preparation systems. After the SMRP, twenty 3DPT printed by PolyJet™ were microCT scanned before preparation and thereafter randomly assigned into two groups (n = 10). One group and NT were prepared using ProTaper Gold® (PTG), and the other group with Endogal® (ENDG). MicroCT scans were carried out after preparation, and the volume increase, volume of dentin removed, centroids, transportation, and unprepared areas were compared. For the parameters evaluated, no significant differences were found between the 3DPT and NT before and after preparation (p > 0.05), and no significant differences were found between the 3DPT PTG group and the 3DPT ENDG group (p > 0.05). It can be concluded that the SMRP described is effective in removing the support material SUP706B™. PolyJet™ is adequate for printing 3DPT. Furthermore, 3DPT printed with high-temperature RGD525™ have similar behaviour during endodontic preparation with PTG as the NT, and 3DPT can be used to compare two preparation systems.

ABSTRACT

Background: Occlusal splints with sensors help in the bruxism diagnosis and monitoring, by recording the patient's bite force. The aim of this study was to evaluate the accuracy of a pressure sensor when it is covered with different thicknesses of a 3D printing resin (Anycubic 405nm Translucent Green UV Resin, Anycubic, UK). Methods: In this preliminary study, the evaluated sensor (FlexiForce A201 Sensor, Tekscan) was firstly calibrated without any type of cover material, and later tested with 3D printing resin with different thicknesses (1 mm, 1.15 mm, 1.4 mm and 1.6 mm). The load tests were performed by a force tester (MultiTest 2.5 dV, Mecmesin). Results: When the pressure sensor was covered with resin of 1mm and 1.6 mm thick specimens, a higher difference was found between the applied load and the corresponding sensor reading. Conclusion: It was concluded that it is possible to use this type of pressure sensor and that it showed better accuracy with the 1.15 mm and 1.4 mm 3D printing resin covering.

ABSTRACT

Resumo Objetivo Analisar o risco de quedas e sua relação com a síndrome da fragilidade e variáveis sociodemográficas em idosos. Métodos Estudo transversal, analítico e multicêntrico, desenvolvido em dois hospitais universitários, no período de agosto de 2019 a janeiro de 2020, com 323 idosos, utilizando o Brazil Old Age Schedule (BOAS) para caracterização sociodemográfica, a Morse Fall Scale (MFS) para definição do risco de quedas e a Edmonton Frail Scale (EFS) para identificação da síndrome da fragilidade. Os dados foram analisados por estatística descritiva e inferencial. Resultados Houve associação entre o risco de quedas e idosos com idade acima de 70 anos, com mais de quatro doenças preexistentes, sem atividade laboral, com déficit cognitivo, estado geral de saúde ruim, com dependência funcional em cinco a oito atividades, fazendo uso de cinco ou mais medicamentos, com perda de peso, baixo desempenho funcional, humor triste ou deprimido e com a síndrome da fragilidade instalada. Idosos que moram sozinhos, com idade acima de 70 anos, que têm quatro ou mais doenças prévias, com dependência funcional, humor deprimido, que realizam o teste Timed Up and Go (TUG) em um tempo maior que 20 segundos, que utilizam cinco ou mais medicamentos por dia e que esquecem de utilizar esses fármacos têm mais chances para o risco de quedas. Conclusão Fatores relacionados ao declínio de funções físicas, psicológicas e mentais nos idosos, e que se encontram exacerbados na síndrome da fragilidade, aumentam o risco para a ocorrência de quedas nessa população.

Abstract Objective To analyze fall risk and its relationship with the frailty syndrome and sociodemographic variables in older adults. Methods This is a cross-sectional, analytical and multicenter study, carried out in two university hospitals, from August 2019 to January 2020, with 323 older adults, using the Brazil Old Age Schedule (BOAS), for sociodemographic characterization, the Morse Fall Scale (MFS), to define fall risk, and the Edmonton Frail Scale (EFS), to identify the frailty syndrome. Data were analyzed using descriptive and inferential statistics. Results There was an association between fall risk and older adults aged over 70 years, with more than four preexisting diseases, without work activity, with cognitive impairment, poor general health status, with functional dependence in five to eight activities, using five or more medications, with weight loss, low functional performance, sad or depressed mood and with the installed frailty syndrome. Older adults who live alone, aged over 70 years, who have four or more previous illnesses, with functional dependence, depressed mood, who perform the Timed Up and Go (TUG) test in a time longer than 20 seconds, who use five or more medications per day and who forget to use these medications are more likely to fall at risk. Conclusion Factors related to the decline of physical, psychological and mental functions in older adults, which are exacerbated in the frailty syndrome, increase fall risk in this population.

ABSTRACT

Purpose: We evaluated the Maximum Elevation of Corneal Back Surface adjusted to the same Best Fit Sphere Back (BFSB) between timeline measurements (AdjEleBmax) and the BFSB radius (BFSBR) itself as new tomographic parameters for documentation of ectasia progression and compare them with the most recent and reliable parameters used on keratoconus (KC) progression. Results: We evaluated the performance and the ideal cutoff point of Kmax, D-index, posterior radius of curvature from the 3.0 mm centered on the thinnest point (PRC), EleBmax, BFSBR, and AdjEleBmax as isolated parameters to document KC progression (defined as a significant change in two or more variables), we found a sensitivity of 70%, 82%, 79%, 65%, 51%, and 63% and a specificity of 91%, 98%, 80%, 73%, 80%, and 84% to detect KC progression. The area under the curve (AUC) for each variable was 0.822, 0.927, 0.844, 0.690, 0.695, 0.754, respectively. Conclusion: AdjEleBmax presented a greater specificity, larger AUC, and better performance compared to EleBmax without any adjustment, with similar sensitivity. Although AdjEleBmax and BFSB demonstrated smaller AUC and specificities comparing with Kmax and D-Index, AdjEleBmax still presented a good performance with a reasonable AUC. Since the shape of the posterior surface, more aspheric and curved than the anterior, may facilitate detection of change, we suggest the inclusion of AdjEleBmax in the evaluation of KC progression in conjunction with other variables to increase the reliability of our clinical evaluation and early detection of progression.

ABSTRACT

Three-dimensional printing offers possibilities for the development of new models in endodontics. Numerous studies have used 3D-printed teeth; however, protocols for the standardization of studies still need to be developed. Another problem with 3D-printed teeth is the different areas of literature requested to understand the processes. This review aims to gather evidence about 3D-printed teeth on the following aspects: (1) why they are advantageous; (2) how they are manufactured; (3) problems they present; and (4) future research topics. Natural teeth are still the standard practice in ex vivo studies and pre-clinical courses, but they have several drawbacks. Printed teeth may overcome all limitations of natural teeth. Printing technology relies on 3D data and post-processing tools to form a 3D model, ultimately generating a prototype using 3D printers. The major concerns with 3D-printed teeth are the resin hardness and printing accuracy of the canal anatomy. Guidance is presented for future studies to solve the problems of 3D-printed teeth and develop well-established protocols, for the standardization of methods to be achieved. In the future, 3D-printed teeth have the possibility to become the gold standard in ex vivo studies and endodontic training.

ABSTRACT

INTRODUCTION: Patients with cancer need to receive their proper treatment and often cannot wait for their treatment, despite delays due to the COVID-19 pandemic. As a result, many cancer centers have had challenges maintaining their oncological activities. OBJECTIVES: To compare the average hospital management data and indicators in two different periods, with and without the peak of COVID-19 cases, from an important tertiary cancer center in the northeast region of Brazil. METHODS: A retrospective and observational study was performed comparing average hospital administrative data and indicators, between January to March v April to June, 2020 exclusively at the Hospital de Câncer de Pernambuco, Brazil. RESULTS: There were on average a 13% reduction in the chemotherapy administered (P = .131), 17% fewer radiotherapy treatments carried out (P = .043) and 41% as many oncologic surgeries undertaken (P = .002). There was a reduction in the number of sessions of out-patient chemotherapy of 8•6% (P = .271) and chemotherapy inpatients of 33% (P = .038). Admission of new cases of patients with cancer was reduced by 44% (P = .007) during the period analyzed. Ambulatory appointments also decreased by 55% (P = .004) and emergency room appointments fell by 7•9% (P = .495). The number of hospitalizations was reduced by 36% (P = .005) and the occupancy rate decreased by 23•6% (P = .003), while the length of individual hospital stays (in days) increased 10•5% (P = .116). CONCLUSION: We report a reduction in the number of radiotherapy treatments and surgeries performed cancer carried out, ambulatory and emergency appointments, hospitalization and admission of new cases of cancer during peak of COVID-19 in an important public tertiary cancer center in the northeast region of Brazil.

ABSTRACT

Atualmente parece existir um paradoxo envolvendo o sistema de justiça: de um lado amplia-se a percepção que em geral não é efetivo, e de outro, expande-se a demanda por sua intervenção para solução de problemas de complexidades variáveis. Entre diversos fatores que poderiam explicar tal paradoxo, esse estudo teórico tem como objetivo analisar a influência da subjetividade pós-moderna na efetividade do sistema de justiça. Por ser a temática desse artigo transdisciplinar – Direito, Psicologia e Sociologia -a partir do paradigma da complexidade de Edgar Morin opta-se pela abordagem sistêmica dos fenômenos, associada à perspectiva teórica sociocultural de construção da subjetividade. Mediante pesquisa bibliográfica qualitativa e de caráter explicativo disserta-se sobre a subjetividade pós-moderna avinda de uma configuração social especifica como limitante para a efetividade jurídica e como variável importante na judicialização. Conclui-se que a justiça que todos buscam está tecida na relação entre o campo jurídico, psicológico e social, sendo que as perspectivas individuais de justiça do sujeito pós-moderno nunca serão atendidas pelo judiciário. E estes dois elementos, sujeito e sistema de justiça, estão imersos numa específica configuração social contemporânea que os constrói e provoca demandas de acordo com ditames de uma sociedade neoliberal.(AU)


There seems to be a paradox involving the Justice System nowadays: in one hand the general notion of its inefficiency is growing, on the other hand, grows the urge for its intervention in solving problems of variable complexities. Among the several factors that could explain said paradox, this theoretical study aims to analyze the influence that post-modern subjectiveness plays in the effectiveness of the justice system. Once the theme of this article is transdisciplinary – Law, Psychology and Sociology – through the complexity paradigm of Edgar Moroni it is chosen to systemically access the phenomena with the theoretical and sociocultural construction of subjectiveness. Through bibliographical qualitative research in an explicative manner, it is written about the post-modern subjectiveness in agreement with a specific social configuration as a constraining to the juridical effectiveness and as a relevant variable in judicialization. There is the conclusion that the form of justice which people seek is woven in the relation among the juridic, psychological and social fields even though the particular expectations on justice for the post-modern individual will never be achieved by the justice system. And those elements, individual and justice system, are immersed in a specific contemporary social configuration that creates demands according to the understandings of a neoliberal society.(AU)

ABSTRACT

BACKGROUND: Many different types of oral overuse behaviours occur frequently in adult populations with painful temporomandibular disorders (TMDs). Less is known regarding these behaviours and their associations with TMDs in university students. OBJECTIVES: Test the association between frequency of different oral overuse behaviours evaluated by the Oral Behaviour Checklist (OBC) and the severity of painful TMDs. METHODS: In this cross-sectional study, 1381 students from 19 universities in the Oporto District, Portugal, completed the Research Diagnostic Criteria for TMD (RDC/TMD) Personal History Questionnaire and the OBC, and they received an RDC/TMD clinical examination. The OBC sum score (ranging from 0 to 84 points) was classified as normal (0 ≤ 16 points), low overuse (17 ≤ 24) or high overuse (≥25). Painful TMD subtypes (myalgia, arthralgia or combined) were identified. Associations were tested using multivariable binary logistic regression models (α = .05), adjusted for age and sex, and referencing the normal parafunction group. RESULTS: University students with high overuse were more likely to have a painful TMD: myalgia (OR = 1.9, 95% CL: 1.3-3.0); arthralgia (OR = 2.2; 95% CL: 1.4-3.4), combined (OR = 5.0; 95% CL: 3.1-8.1). Students with low overuse were more likely to have only the combined painful TMD (OR = 2.4; 95% CL: 1.4-4.0) but not the individual painful disorders. Of the 21 different behaviours, 13 were reported at least 50% of the time. CONCLUSIONS: In this university student sample, oral overuse behaviours are widespread, and their overall extent exhibited a dose-response relationship with respect to severity of painful TMDs based on pain and chronicity. Only some behaviours were independently associated with painful TMDs, suggesting the value of further OBC instrument development.

ABSTRACT

Buscamos compreender a relação entre a prática artística do grupo "Meninas de Sinhá" e a memória, como processo cognitivo e cultural vivenciado na velhice. A memória das brincadeiras de roda da infância constitui-se como matéria-prima de criações artísticas coletivas do grupo. Realizamos uma abordagem qualitativa, com revisão bibliográfica e observação participante registrada em diário de campo. Discutimos os conceitos apropriados pela revisão bibliográfica a partir das vivências do "Meninas de Sinhá". Concluímos que, o processo de criação pode ser um recurso para que, na velhice, perdure a escrita autoral da vida. E que, nesta escrita, a memória e outros elementos da cognição sejam preservados e estimulados. O processo de criação demanda alta atividade cognitiva, e no caso da criação coletiva, amplia a participação social e cultural, a troca de sensibilidades e cuidados.


We sought to understand the relationship between the community artistic practice of the group "Meninas de Sinhá" and memory, as a cognitive and cultural process experienced in old age. The memory of children's wheel games constitutes the raw material of collective artistic creations of the group. We performed a qualitative approach, with bibliographic review and participant observation recorded in field diaries. We discuss the concepts appropriated by the bibliographical review from the experiences of the "Meninas de Sinhá". We conclude that, the process of creation can be a resource so that, in old age, the authorial writing of life lasts. And that in this writing, memory and other elements of cognition are preserved and stimulated. The process of creation demands high cognitive activity, and in the case of collective creation, it increases social and cultural participation, the exchange of sensibilities and care.

ABSTRACT

BACKGROUND: Zika-exposed infants with microcephaly (proportional or disproportional) and those who are small for gestational age without microcephaly should be closely followed, particularly their growth trajectories. They are at high risk of adverse outcomes in the first year of life.Antenatal Zika virus (ZIKV) exposure may lead to adverse infant outcomes including microcephaly and being small for gestational age (SGA). ZIKV-exposed infants with a diagnosis of microcephaly (proportional [PM] or disproportional [DM]) or SGA at birth were evaluated with anthropometric measurements and health outcomes. METHODS: Infants had laboratory-confirmed ZIKV exposure in Brazil. PM, DM, or SGA classification was based on head circumference and weight. First-year growth parameters and clinical outcomes were recorded with analyses performed. RESULTS: Among the 156 ZIKV-exposed infants, 14 (9.0%) were SGA, 13 (8.3%) PM, 13 (8.3%) DM, and 116 (74.4%) were neither SGA nor had microcephaly (NSNM). High rates of any neurologic, ophthalmologic, and hearing abnormalities were observed for PM (100%), DM (100%), and SGA (42.9%) vs NSNM infants (18.3%; P <.001); odds ratio [OR], 3.4 (95% confidence interval [CI], 1.1-10.7) for SGA vs NSNM. Neuroimaging abnormalities were seen in 100% of PM and DM and in 42.9% of SGA vs NSNM infants 16%; (P <.001); OR 3.9 (95% CI, 1.2-12.8) for SGA vs NSNM. Growth rates by z score, particularly for microcephaly infants, were poor after birth but showed improvement beyond 4 months of life. CONCLUSIONS: ZIKV-exposed infants with microcephaly (PM and DM) had similarly high rates of adverse outcomes but showed improvement in growth measurements beyond 4 months of life. While SGA infants had fewer adverse outcomes compared with microcephaly infants, notable adverse outcomes were observed in some; their odds of having adverse outcomes were 3 to 4 times greater compared to NSNM infants.Zika-exposed infants with microcephaly, irrespective of being proportional or disproportional, and those who are small for gestational age without microcephaly should be closely followed, particularly their growth trajectories. They are at high risk of adverse outcomes in the first year of life.

ABSTRACT

Importance: Congenital Zika virus (ZIKV) infection may present with a spectrum of clinical and neuroradiographic findings. Objective: To determine whether neuroimaging findings for infants with a history of ZIKV exposure are associated with infant clinical outcomes and gestational age at antenatal ZIKV infection. Design, Setting, and Participants: This cohort study retrospectively reviewed neuroimaging results (computed tomography and/or magnetic resonance imaging scans) of 110 ZIKV-exposed infants from a maternity and children's hospital in Rio de Janeiro, Brazil, following the 2015 to 2016 ZIKV epidemic. Neuroimaging from March 1, 2016, to June 30, 2017, was evaluated to determine whether findings were associated with clinical outcomes and the timing of maternal ZIKV infection. Data were analyzed from July 1, 2017, to August 30, 2018. Exposures: Neuroimaging (computed tomography and/or magnetic resonance imaging) was performed on ZIKV-exposed infants after birth. Blood and/or urine specimens from mothers and infants were tested for ZIKV by polymerase chain reaction assay. Main Outcomes and Measures: Neuroimaging studies were evaluated for structural abnormalities and other forms of brain injury. Results: A total of 110 infants with a mean (SD) gestational age of 38.4 (2.1) weeks had neuroimaging and clinical outcome data reviewed. Of these, 71 (65%) had abnormal neuroimaging findings, with the majority (96%) classified as having severe ZIKV infection at birth. The most common neuroimaging abnormalities were structural abnormalities including brain calcifications, especially at the cortico-subcortical white matter junction, cortex malformations, ventriculomegaly, and reduced brain volumes, followed by brainstem hypoplasia, cerebellar hypoplasia, and corpus callosum abnormalities. Frequency of abnormal imaging was higher in infants with specific clinical findings as opposed to those without them; these findings included fetal brain disruption sequence (100% vs 35%), microcephaly (100% vs 30%), congenital contractures (100% vs 58%), ophthalmologic abnormalities (95% vs 44%), hearing abnormalities (100% vs 58%), and neurologic symptoms (94% vs 10%). Four of 39 infants (10%) without initial evidence of severe ZIKV infection and normal findings on neurologic evaluation at birth had abnormal neuroimaging findings. Neuroimaging abnormalities differed by trimester of maternal ZIKV infection, with 63% of infants born to mothers infected in the first trimester, 13% of infants born to mothers infected in the second trimester, and 1% of infants born to mothers infected in the third trimester exhibiting neuroimaging abnormalities. The odds of abnormal neuroimaging were 7.9 times greater for infants with first trimester ZIKV exposure compared with other trimesters combined (odds ratio, 7.9; 95% CI, 3.0-20.4; P < .001). Conclusions and Relevance: Neuroimaging abnormalities of computed tomography and/or magnetic resonance imaging scans were common in ZIKV-exposed infants. While neuroimaging abnormalities were seen in 10% of infants without clinically severe ZIKV, most occurred almost exclusively among those with clinically severe ZIKV, especially among those with a history of ZIKV exposure in the first trimester.

ABSTRACT

OBJECTIVES: The purpose of this study was to describe the metabolic and anthropometric profile of the Xikrin (Mebengôkre), an indigenous group. METHODS: A total of 363 subjects (55.1% women) aged 18 years or older were evaluated. The variables analyzed were age, body weight and height, waist circumference, blood pressure, fasting blood glucose, triglyceride level, and total cholesterol level. RESULTS: A high prevalence of obesity (36.5%) and central obesity (88.1%), mainly among women (46.9% and 96.2%, respectively), was found among the Xikrin (Mebengôkre). Impaired fasting glycemia and diabetes were found in 4.5% and 3.8% of adults, respectively. Twenty-one percent of adults had dyslipidemia and 9.3% had hypertension. CONCLUSIONS: The high prevalence of excess weight (overweight and obesity) and central obesity, especially in women, was the most significant finding of this study among the Xikrin (Mebengôkre).

ABSTRACT

BACKGROUND: Oral behaviors (OBs) must be assessed as part of a biobehavioural evaluation for patients with temporomandibular disorders (TMD). OBJECTIVES: The aims of this study were: to translate and culturally adapt the Oral Behaviors Checklist (OBC) into Portuguese; to evaluate its basic psychometric properties; and to assess the utility of the Portuguese OBC. METHODS: The Portuguese translation, cross-cultural equivalence, and two studies (Pre-field test, N = 8, and field test, N = 45) of the OBC adhered to official guidelines of the International RDC/TMD Research Consortium (now, INfORM). In the formal test (N = 120) the Portuguese RDC/TMD was used for TMD diagnosis. RESULTS: Translation and cultural equivalence of the OBC into Portuguese was reviewed and approved by an expert panel. In the field test, item agreement between English and Portuguese OBC versions was very good (weighted Kappa ≥ 0.934). Test-retest reliability of the OBCS umScore was excellent intra-class correlation coefficient ((ICC) = 0.998, P < 0.001). As an initial probe into validity using parallel forms, comparison of the sleep bruxism and awake clenching questions included in the RDC/TMD with the corresponding OBC questions yielded excellent (Kappa = 0.932) and very good (k = 0.850), respectively, convergent validity as well as excellent (that is, poor agreement, kappa = 0.013) discriminant validity for these specific OBs. The mean OBCS umScore was significantly lower for the healthy group, compared to the painful TMD group (ANOVA, P = 0.037). CONCLUSIONS: The Portuguese translation of the OBC exhibits cross-cultural equivalence for use in Portugal, and the instrument performs with acceptable psychometric properties. The validity of the parafunction construct requires additional research in both Portuguese and other languages.

ABSTRACT

Ivermectin (IVM) is an antiparasitic agent widely used in agricultural, domestic animals and in human clinical practice. In the present study, the temporal effects of therapeutic doses of IVM in the morphometric and histological assessment of testis were studied to verify if IVM acute administration impaired the spermatogenesis and spermiogenesis of adult rats, if these effects are reversible. The testosterone levels and the plasmatic IVM levels were assessed. The results show: 1) IVM acute exposure, mainly in the higher dose, reduced the testicular volume, the tubular diameter and the germinal epithelium height; 2) no interferences on Leydig cells frequency; 3) histological studies show that tubular sections containing several histological changes indicative of spermatogenesis interruption, such as disorganization of germinal epithelium, vacuolar degeneration of the germ cells and sloughing of cells into the tubular lumen; 4) no differences in testosterone levels; 5) The IVM plasmatic levels were significantly reduced at 72h after the 0.2mg/kg. It was concluded that acute IVM impaired the spermatogenesis and spermiogenesis of rats. Probably these effects were not consequence of IVM at the Leydig cells because no effects were observed at this level. Finally, our results suggest that some testicular effects are reversible and correlated with the plasmatic levels of IVM.

ABSTRACT

INTRODUCTION: Due to Plasmodium resistance to antimalarial drugs, it is important to find new therapeutic alternatives for malaria treatment and control. Based on the knowledge of Colombian indigenous communities, we collected extracts of plants with potential antimalarial effects from the middle Vaupés region. OBJECTIVE: To evaluate the mutagenic and genotoxic effects, as well as the gene expression of Rad51C, Xiap, P53 and Nrf2 induced by four ethanolic extracts with antimalarial activity (R001, T002, T015 and T028). MATERIALS AND METHODS: We evaluated four ethanolic extracts with antimalarial activity using the Ames test to assess mutagenicity, and the comet assay on HepG2 cells to determine the genotoxicicity. We also evaluated the expression of Rad51C, Xiap, P53 and Nrf2 from HepG2 cells stimulated with the four extracts. RESULTS: None of the four extracts was mutagenic in Salmonella typhimurium TA98 strain in the presence and absence of S9 metabolic activity. Extracts R001, T015 and T028 were weakly mutagenic on the TA100 strain in the presence of S9, with mutagenic indexes (MI) of 1.58, 1.53 and 1.61, respectively. The T015 strain showed the same behavior without S9 with an MI of 1.36. The results of the comet assay showed that the four extracts produced category 1 or 2 damage, with comets between 36.7 and 51.48 µm in length. However, the genetic damage index suggested that most of the cells were affected by the treatments. Regarding gene expression, extracts R001 and T028 induced an overexpression of genes Xiap and P53 with an 1.84 to 3.99 fold-change compared with untreated cells. CONCLUSIONS: These results revealed that the T002 extract was the safest as it had antimalarial activity and was not cytotoxic on HepG2 cells. Moreover, it was not mutagenic and it only produced category 1 damage on the DNA. Also, the extract did not induce a change in the expression of the tested genes.

ABSTRACT

Resumen Introducción. Dada la resistencia de Plasmodium a los medicamentos antipalúdicos, es necesario encontrar nuevas alternativas terapéuticas para su tratamiento y control. Con base en el saber indígena colombiano, se recopilaron extractos de plantas del Vaupés medio con potencial efecto antipalúdico. Objetivo. Evaluar el efecto mutagénico y genotóxico, y la expresión de los genes Rad51C, Xiap, P53 yNrf2, inducidos por cuatro extractos etanólicos con actividad anti-Plasmodium(R001, T002, T015 y T028). Materiales y métodos. Se evaluó el potencial mutagénico de cuatro extractos etanólicos con efecto antiplasmódico utilizando el test de Ames y el efecto genotóxico, con un ensayo del cometa; asimismo, se analizó la expresión de los genes Rad51C, Xiap, P53 y Nrf2 en células HepG2. Resultados. Los extractos no fueron mutágenos en la cepa TA98 de Salmonella typhimurium en presencia y ausencia de actividad metabólica de la fracción S9. En la cepa TA100, los extractos R001, T015 y T028 se comportaron como mutágenos débiles en presencia de S9, con índices mutagénicos de 1,58; 1,38; 1,53 y 1,61, respectivamente; T015 tuvo el mismo comportamiento en ausencia de S9, con un índice mutagénico de 1,36. En el ensayo del cometa, todos los extractos provocaron daño de categorías 1 o 2, con colas de cometas entre 36,7 y 51,48 µm de longitud; sin embargo, el índice dedaño genético sugirió que los tratamientos afectaron la mayoría de las células. En los genes en estudio, los extractos R001 y T028 indujeron una sobreexpresiónde 1,84 a 3,99 frente a las células sin tratar de los genes Xiap y P53. Conclusiones. Los resultados evidenciaron que el extracto T002 fue el más seguro, ya que presentó actividad anti-Plasmodium, no fue citotóxico en las células HepG2, no fue mutágeno, causó daño de categoría 1 en el ADN y no modificó la expresión de los genes evaluados.
