    BARBEZAN, ANGELICA B. ; MARTINS, REGIANE ; BUENO, JENNIFER B. ; VILLAVICENCIO, ANNA L.C.H. . Ames test to detect mutagenicity of 2-alkylcyclobutanones: a review. Journal of Food Science, v. 00, n. 0, p. 1-5, 2017. DOI: 10.1111/1750-3841.13721

    Abstract: Food irradiation is an effective and safe method for preservation and long-term storage, and it is approved for use in over 60 countries for various applications in a wide variety of food products. This process is performed by use of accelerated electron beams, X-rays, or gamma radiation (60Co or 137Cs). 2-Alkylcyclobutanones (2-ACBs) are the only known radiolytic products generated from foods that have fatty acids (triglycerides) and are subjected to irradiation. Since the 1990s toxicological safety studies of 2-ACBs have been conducted extensively through synthetic compounds, then and tests to determine if the compounds have any mutagenic activity are strictly necessary. The Ames test was chosen by many researchers to assess the mutagenicity of 2-ACBs. The test uses distinct bacterial cell lines Salmonella typhimurium to detect point mutations at sites guanine–cytosine (G–C) and Escherichia coli to detect point mutations at sites adenine–thymine (A–T). This bibliographic research aims to bring together all the results obtained and a comparison and cell lines used, type of plates, and solvents. This research showed that no mutagenic activity was observed in any of the cell lines and concentrations evaluated by the works of authors, so the 2-ACBs compounds showed no mutagenic substance in concentrations detectable by the Ames test.

    RODRIGUES, FLAVIO T. ; MARCHIONI, ERIC; LORDEL-MADELEINE, SONIA; KUNTZ, FLORENT; VILLAVICENCIO, ANNA L.C.H. ; JULIEN-DAVID, DIANE. Degradation of profenofos in aqueous solution and in vegetable sample by electron beam radiation. Radiation Physics and Chemistry, v. 166, p. 1-7, 2020. DOI: 10.1016/j.radphyschem.2019.108441

    Abstract: In this study, the role of accelerated electron irradiation on the removal of profenofos in aqueous solution and in peas was investigated. The samples were irradiated with a Rhodotron E-beam accelerator with 10 MeV energy at doses of 0 (control), 4.6, 12 and 32 kGy. Irradiated vegetable samples were extracted using a QuEChERS protocol (quick, easy, cheap, effective, rugged, and safe), allowing analysis of pesticide traces. Quantification of profenofos in aqueous solution was performed by using GC-MS in SIM mode and GC-MS/MS in MRM mode in vegetable sample. Degradation of profenofos increased with the E-beam dose and was much more important in aqueous solution than in vegetable. In irradiated aqueous solution, one degradation product was detected.

    LEVY, DENISE ; VILLAVICENCIO, ANNA L.C.H. . Educating the educators: interdisciplinary approaches to enhance science teaching. World Academy of Science, Engineering and Technology: International Journal of Educational and Pedagogical Sciences, v. 13, n. 9, p. 1206-1209, 2019. DOI: 10.5281/zenodo.3461956

    Abstract: In a rapid-changing world, science teachers face considerable challenges. In addition to the basic curriculum, there must be included several transversal themes, which demand creative and innovative strategies to be arranged and integrated to traditional disciplines. In Brazil, nuclear science is still a controversial theme, and teachers themselves seem to be unaware of the issue, most often perpetuating prejudice, errors and misconceptions. This article presents the authors’ experience in the development of an interdisciplinary pedagogical proposal to include nuclear science in the basic curriculum, in a transversal and integrating way. The methodology applied was based on the analysis of several normative documents that define the requirements of essential learning, competences and skills of basic education for all schools in Brazil. The didactic materials and resources were developed according to the best practices to improve learning processes privileging constructivist educational techniques, with emphasis on active learning process, collaborative learning and learning through research. The material consists of an illustrated book for students, a book for teachers and a manual with activities that can articulate nuclear science to different disciplines: Portuguese, mathematics, science, art, English, history and geography. The content counts on high scientific rigor and articulate nuclear technology with topics of interest to society in the most diverse spheres, such as food supply, public health, food safety and foreign trade. Moreover, this pedagogical proposal takes advantage of the potential value of digital technologies, implementing QR codes that excite and challenge students of all ages, improving interaction and engagement. The expected results include the education of the educators for nuclear science communication in a transversal and integrating way, demystifying nuclear technology in a contextualized and significant approach. It is expected that the interdisciplinary pedagogical proposal contributes to improving attitudes towards knowledge construction, privileging reconstructive questioning, fostering a culture of systematic curiosity and encouraging critical thinking skills.

    LEVY, DENISE ; PERALTA, TELMA M.; POZZI, LORENY; TOVAR, IZI P. de; SANTOS, IGOR P. dos; VILLAVICENCIO, ANNA L.C.H. . Education and citizenship: contributions of psychopedagogical practices to popularization of science. International Journal of Development Research, v. 07, n. 07, p. 14157-14162, 2017.

    Abstract: In the so-called Information Society, knowledge is a powerful tool for real social inclusion. Inclusion through knowledge is a citizen attitude, as it changes students’ perceptions, allowing critical thinking, stimulating the ability to question the world and encouraging to change reality as active citizens. Popularization of science is a must and a challenge. In a globalized world where the Internet seems to be the largest vehicle for information, offering children and young people the illusion of unlimited knowledge, the traditional academic practices do not seem to correspond to the student's desire of learning. Under the light of psycho-pedagogical perspective, we can discuss different possibilities to communicate science in the academic context, at different ages, from pre-school to university. This article brings together the experience of six educational professionals who use the psycho-pedagogical know-how to promote a meaningful and interesting learning. Psycho-pedagogical practices consider the singularity of each group, students protagonists in learning process, stimulating reconstructive questions, re-signifying previous knowledge, making knowledge meaningful and relevant, thus articulating student´s desire to the scientific discourse.

    ALMEIDA, MARIANA C. ; SAMPAIO, GENI R.; BASTOS, DEBORAH H.M.; VILLAVICENCIO, ANNA L.C.H. . Effect of gamma radiation processing on turmeric: antioxidant activity and curcumin content. Radiation Physics and Chemistry, v. 152, p. 12-16, 2018. DOI: 10.1016/j.radphyschem.2018.07.008

    Abstract: The aim of this study was to evaluate the effectiveness of gamma radiation from 60Co at doses 0, 5, 10, 15 and 20 kGy on turmeric (Curcuma longa Linn.). The quantification of phenolic compounds was performed by Folin-Ciocalteu method and assessing the potential of antioxidant activity by the free radical [2,2 difenil-1-pricril-hidrazil (DPPH•)] scavenging and by Rancimat® method. The curcumin quantification was performed by High Performance Liquid Chromatography. Compared to control, there were significant losses (p < 0,05) of total phenolic compounds in the samples irradiated with 15 kGy (p = 0001) and 20 kGy (p = 0001). Regardless the irradiation, there was no decrease in the ability to scavenge free radicals. The Antioxidant Activity Index (Rancimat® method) was significantly lower (p < 0,05) in 5 kGy (p < 0001) and 15 kGy (p = 0003) irradiated extracts and the curcumin quantification was significantly lower (p < 0,05) in 15 kGy irradiated extract (p < 0001). It is concluded that gamma radiation processing technology on turmeric can be viable. To maintain safety of antioxidant activity it should be applied doses up 10 kGy.

    SÁ, ANA P.N. de ; NEGRAO, BIANCA G. ; NABESHIMA, ELIZABETH H.; KOIKE, AMANDA C.R. ; VILLAVICENCIO, ANNA L.C.H. . Effect of ionizing radiation on traditional and bacon “farofa”. Radiation Physics and Chemistry, v. 179, p. 1-7, 2021. DOI: 10.1016/j.radphyschem.2020.109109

    Abstract: Seasoned “farofa” is a typical Brazilian dish made with toasted cassava flour. It is known that ionizing radiation is widely employed to improve food products extending its shelf life. In this context, this work analyzes the effects of ionizing radiation on the rheological and physicochemical properties of bacon (BF) and traditional (TF) “farofa”. The samples were obtained from local markets (São Paulo/Brazil) and irradiated in the electron beam accelerator of Nuclear and Energy Research Institute (IPEN/CNEN-SP, São Paulo, Brazil) in doses of 1, 5 and 10 kGy, and analyzed on the first, fifteenth and thirtieth storage day. The results showed that the irradiated TF and BF samples displayed acidic pH throughout the storage period, regardless of dose increase. The different irradiation doses did not significantly affect (Tukey test p > 0.05) the water activity, keeping the products in the safe range. The colorimetric analysis, also showed no significant difference (p ≥ 0.05) among the samples and ionizing radiation doses, indicating that the yellowish coloration remained stable throughout the experiment. After the thirtieth day, the moisture of the TF and BF samples ranged from 7.06% to 9.75%. Irradiation had a significant impact on the viscosity profile and texture characteristics of the “farofa”, such as hardness, cohesiveness, and the springiness at 5 and 10 kGy.

Effects of electron beam irradiation on the bioactive components of goji-berry. Radiation Physics and Chemistry, v. 179, p. 1-5, 2021. DOI: 10.1016/j.radphyschem.2020.109144

    Abstract: The goji-berry (Lycium barbarum) is an oval-shaped orange-red fruit with a slightly sweet flavor. This berry has a high antioxidant potential and presents interesting nutritional and therapeutic properties. Irradiation is a safe method that has long used to reduce the microbiological contamination of dried and dehydrated food products. This study aimed to evaluate the irradiation effects on the bioactive compounds of goji berries by irradiating samples with an electron beam at doses of 2.5, 5.0, 7.5, and 10.0 kGy. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity and oxygen radical absorbance capacity (ORAC) were assessed by analyzing the hydroalcoholic extracts. The total phenolic compounds determined by the Folin-Ciocalteu assay. Doses up to 10.0 kGy did not significantly affect the antioxidant activity in the DPPH assay, and electron beam irradiation improved the total antioxidant activity of the samples in ORAC, as well as a total flavonoid and phenolics assays.

    BARBEZAN, ANGELICA B. ; SANTOS, CARLA J.B. ; CARVALHO, LUMA R. ; VIEIRA, DANIEL P. ; SANTELLI, GLAUCIA M.M.; VILLAVICENCIO, ANNA L.C.H. . Flow cytometry based micronucleus assay for evaluation of genotoxic potential of 2-ACBs in hepatic cells HepG2. Brazilian Journal of Radiation Sciences, v. 7, n. 2A, p. 1-24, 2019. DOI: 10.15392/bjrs.v7i2A.684

    Abstract: Food irradiation is approved for use in more than 60 countries for applications and purposes in a wide variety of foods, being an effective and safe method for preservation and long-term storage. 2- Alkylcyclobutanones (2-ACBs) are the only known radiolytic products generated from foods that contain fatty acids (Triglycerides) when irradiated. The acids analyzed in this study are palmitic and stearic, which when irradiated form 2-Dodecylcyclobutanones (2-dDCB) and 2-Tetradecylcyclobutanone (2-tDCB). Part of the 2-ACBs ingested is excreted through feces and part is deposited in adipose tissues. In vitro studies so far have been only in colon cells. The work used a human hepatoma cell line (HepG2) since the accumulation of fat in this organ is quite common. Micronucleus test was selected to evaluate possible genotoxic effects of 2-dDCB and 2-tDCB compounds when exposed to high concentrations (447, 1422 and 2235 μM) for 4 and 24 hours. Tests were performed in quadriplicates using flow cytometric analysis. None detectable genotoxic damage was observed after 4 hours of exposure to the compounds, and cytotoxic effects were only significant at the highest concentration (2235 μM) of 2-dDCB. After 24 hours of exposure, slight genotoxic damage was observed at all concentrations evaluated, and cytotoxic effects were only present when exposed to compound 2-tDCB. Although there is a genotoxic and cytotoxic effect in some of the situations tested, the two compounds predominantly induced proliferation reduction effects of this hepatic tumor cell line.

    BALDO, FERNANDO B.; VILLAVICENCIO, ANNA L.C.H. ; SCHMIDT, FLAVIO L.; RAGA, ADALTON. Gamma radiation as a potential phytosanitary squash treatment for the control of Anastrepha grandis (Macquart) (Diptera: Tephritidae). Annual Research & Review in Biology, v. 36, n. 4, p. 19-31, 2021. DOI: 10.9734/arrb/2021/v36i430360

    Abstract: Fruit flies (Diptera: Tephritidae) are the primary pests of horticultural crops worldwide, causing both direct and indirect damage to the fruit production, including Anastrepha grandis (Macquart, 1846), which exclusively infests Cucurbitaceae fruit. Dose-response tests were used to examine the effects of gamma radiation exposure on 24 – 48 h old eggs and third instar larvae, both in vitro and in Atlas squashes (Cucurbita moschata). The following physicochemical properties of Atlas squashes exposed to gamma radiation were evaluated: titratable total acidity, sugar, pH, external colouration, and texture. It was found that under in vitro conditions, a 20.0 Gy dose of gamma radiation was able to prevent larval eclosion, but a 200 Gy dose was necessary to prevent emergence after the exposure of third instar larvae. In Atlas squashes, 200 and 250 Gy doses of gamma radiation were able to prevent the emergence of A. grandis adults from eggs and larvae, respectively. The radiation doses estimated by Probit 9 to prevent emergence from squashes infested with eggs and third instar larvae were 257.13 Gy and 270.25 Gy respectively. The use of gamma radiation did not significantly affect the physicochemical properties of Atlas squashes, which suggested that gamma radiation may represent a potentially useful technique for the quarantine control of A. grandis in cucurbits.

The influence of electron beam radiation in the nutritional value, chemical composition and bioactivities of edible flowers of Bauhinia variegata L. var. candida alba Buch.-Ham from Brazil. Food Chemistry, v. 241, p. 163-170, 2018. DOI: 10.1016/j.foodchem.2017.08.093

    Abstract: As edible flowers are highly perishable, irradiation technology can be applied to increase their shelf life, as also for phytosanitary purposes. Herein, flowers of Bauhinia variegata L. var. candida alba Buch.- Ham were submitted to electron beam irradiation at the doses of 0.5, 0.8 and 1 kGy, to study the effects in the nutritional and chemical profiles, and also in antioxidant, cytotoxic and anti-inflammatory activities. The petals of white flowers revealed interesting bioactive properties being kaempferol derivatives the most abundant compounds, especially kaempferol-3-O-rutinoside. The applied irradiation doses did not highly affect the nutritional profile. No changes were produced in cytotoxicity, but the anti-inflammatory activity slightly decreased. However, the antioxidant activity was increased, especially in the dose of 0.5 kGy, in agreement with the higher content in phenolic compounds found at this dose.

É compatível com o Protocolo de Arquivos Abertos (OAI) permitindo interoperabilidade com repositórios de âmbito nacional e internacional.

O gerenciamento do Repositório está a cargo da Biblioteca do IPEN. Constam neste RI, até o presente momento 20.950 itens que tanto podem ser artigos de periódicos ou de eventos nacionais e internacionais, dissertações e teses, livros, capítulo de livros e relatórios técnicos. Para participar do RI-IPEN é necessário que pelo menos um dos autores tenha vínculo acadêmico ou funcional com o Instituto. Nesta primeira etapa de funcionamento do RI, a coleta das publicações é realizada periodicamente pela equipe da Biblioteca do IPEN, extraindo os dados das bases internacionais tais como a Web of Science, Scopus, INIS, SciElo além de verificar o Currículo Lattes. O RI-IPEN apresenta também um aspecto inovador no seu funcionamento. Por meio de metadados específicos ele está vinculado ao sistema de gerenciamento das atividades do Plano Diretor anual do IPEN (SIGEPI). Com o objetivo de fornecer dados numéricos para a elaboração dos indicadores da Produção Cientifica Institucional, disponibiliza uma tabela estatística registrando em tempo real a inserção de novos itens. Foi criado um metadado que contém um número único para cada integrante da comunidade científica do IPEN. Esse metadado se transformou em um filtro que ao ser acionado apresenta todos os trabalhos de um determinado autor independente das variáveis na forma de citação do seu nome.
