Abstract Antispastis Meyrick, 1926 is a poorly known genus of leaf-mining micromoths endemic to the Neotropics, with still uncertain taxonomic position within the Yponomeutoidea. In the present study, the egg, larva and pupa of A. clarkei Pastrana, previously known only from Argentina, are described and illustrated with the aid of optical and scanning electron microscopy. Data on life history, including histology of the mine, are also provided. Family placement of the genus is reassessed based on comparison of morphology and DNA sequences with closely related lineages. The larvae form blotch mines on the upper surface of Solanum L. (Solanaceae) leaves, feeding on palisade parenchyma in all instars. Pupation occurs outside the mine, in an inverted basket-like, large-meshed cocoon constructed on the plant surface. DNA analysis of Cytochrome oxidase I gene of A. clarkei revealed interspecific differences averaging 10% with A. xylophragma, which provided species separation matching morphological differences. Antispastis was closely related phylogenetically to Digitivalva, clustering in the Acrolepiinae together with the genera Acrolepia and Acrolepiopsis, and ultimately placed within Glyphipterigidae. The geographical distribution of A. clarkei is expanded to the Southern Atlantic forest (Rio Grande do Sul and Paraná states, Brazil).

ABSTRACT During recent studies performed in the Atlantic Forest, a new species of Phyllocnistinae (Gracillariidae), Phyllocnistis hemera sp. nov., leaf miner of Daphnopsis fasciculata (Thymelaeaceae) was discovered. The adults are described and illustrated as well as the immature stages, with notes on natural history including a description of the leaf mine. Additionally, DNA barcode sequences were compared to other representatives of Phyllocnistinae to test for the specific status of P. hemera and to infer phylogenetic relationships. This is the fifth species described for the genus Phyllocnistis in the Atlantic Forest and the first record of a gracillarid mining Thymelaeaceae leaves.

ABSTRACT Gracillariidae (Lepidoptera) are commonly known by the leaf miner habit found in the larval stage of most species. By using worldwide, public databases on species diversity and DNA sequences available for extant gracillariid species, we determined changes in the rate of taxonomic species descriptions through time, mapped their spatial distributions, examined their phylogenetic diversification, and estimated the number of species yet to be described for the family in the Neotropics. We recovered 185 species, a number that is smaller than that found in any other biogeographic region. However, it was estimated that at least 3875 additional species remain to be described in the region. Phylogenetic diversification showed a pattern of expanding diversity. A few entomologists have been involved with gracillariid taxonomy in the Neotropics, having 39% of the species been described by a single taxonomist. In most of such cases, descriptions were based on the adults only. A few species have been described from biomes known to have some of the greatest diversity on earth, such as the Atlantic Forest. Thus, such a scenario results from low sampling and scarce taxonomic activity that has prevailed for this family of moths in the Neotropics. It may also be associated with their small body size and to the fact that gracillariids do not seem to be attracted to light traps as much as other moths, which make their collection and identification by non experts difficult. We also suggested scientific and political actions that could be adopted to overcome such an unfavorable scenario.

ABSTRACT A descriptive cross-sectional study with quantitative and qualitative approach that aimed to investigate the nurses’ knowledge and perception of adverse effects, reporting of such events and factors that may limit reporting. Data collection was performed between November and December 2015 in a public hospital of the Center-South region of the state of Sergipe. The sample was composed of 28 nurses who completed a semi-structured form analyzed through descriptive statistics and content analysis. Among the participants, 16 (57%) were 16 (57%) showed little knowledge on adverse events, and, 27 (96%) respondents perceived the importance of reporting. However, these events are underreported due to fear of punishment, among other factors. It is concluded that educational actions and measures aimed to clarify these health professionals on adverse events and encourage reporting are needed.

ABSTRACT Elachista synethes was recently recognized as an alien species in northern Chile, where its larvae mine the rescue grass Bromus catharticus (Poaceae). In order to provide the necessary information to allow field detection of E. synethes during early ontogeny, we conducted a morphological reappraisal of the immature stages of this leaf-miner moth, based on light and scanning electron microscopy, including the first descriptions of the egg and the first-instar larva. This is the first report of the existence of an apodal early larva for a species of Elachista Treitschke. The legs and prolegs are absent in the first two instars, but are well developed in the last two. Additional observations on the life history are also provided, including a description of the mine.

OBJETIVO: Verificar o efeito do óleo de copaíba da espécie Copaifera officinalis no carcinoma de Walker 256 inoculado em vagina e colo de útero de ratas. MÉTODOS: Foram utilizadas 18 ratas da linhagem Wistar, pesando entre 180-250g, distribuídas em dois grupos (CCop, GC). No 1º dia de experimento, em ambos os grupos foi inoculado 0,3ml de tumor de Walker 256 na concentração de 2x10(6); no 3º dia após essa inoculação, foi iniciada a administração de água destilada na dose de 4,8 ml/kg ao GC, e copaíba na dose de 4,8 ml/kg ao GCop. No 12º dia foi realizada a eutanásia das ratas e ressecado o tumor, sendo este pesado e averiguado seu volume. Os dados obtidos foram submetidos à análise estatística pelo método ANOVA. RESULTADOS: Observou-se que o óleo de copaíba apresentou um potencial inibitório negativo de 70%. CONCLUSÃO: O óleo de copaíba estimulou o crescimento tumoral.

PURPOSE: To verify the copaiba balsam (Copaifera officinalis) effect on Walker 256 carcinoma inoculated into vagina and uterine cervix of rats. METHODS: Eighteen female Wistar rats weighing between 180-250g were used, distributed into 2 groups (GCop, GC). On the 1st day of the experiment, 0.3 ml of Walker 256 carcinoma (2x10(6) concentration) was inoculated in both groups; on the 3rd day of the experiment, it was given 4.8 ml/kg of distilled water to the GC group, and 4.8 ml/kg of copaiba balsam to the GCop group. On the 12th day, euthanasia was performed and the tumor was grafted, being weighted and verified its volume. The data were submitted to statistical analysis with ANOVA test. RESULTS: It was observed that copaiba balsam presented a negative inhibitory potential of 70%. CONCLUSION: The copaiba balsam stimulated the tumor growth.

OBJETIVO: Verificar o efeito da ooforectomia à inoculação do tumor de Walker 256 em vagina e colo de útero de ratas. MÉTODOS: Foram utilizadas 10 ratas Wistar, fêmeas, virgens, adultas, distribuídas em dois grupos de estudo com 05 animais cada: grupo tumor (GT): ratas inoculadas com tumor de Walker 256, e grupo Ooforectomia (GO): ratas ooforectomizadas e inoculadas com tumor de Walker 256. No dia anterior à inoculação vaginal do tumor, foram inoculados 0,3ml de ácido acético na vagina das ratas de ambos os grupos; no dia seguinte, foi realizada a escarificação da parede vaginal com uma escova de endocérvice e inoculado tumor de Walker 256. Após 12 dias, foi removido o tumor em bloco com vagina e cornos uterinos para análise macro e microscópica. Os dados foram submetidos à análise estatística. RESULTADOS: Não houve diferença estatística entre os dois grupos; no entanto, notou-se que o comportamento de crescimento do tumor no grupo GO apresentou maior invasividade em extensão, comprometendo cornos uterinos. CONCLUSÃO: Observou-se que o grupo GO apresentou comportamento macroscópico diferente ao grupo GT, no entanto, em termos totais de massa tumoral ambos apresentam desenvolvimento similar.

PURPOSE: Verify the effect of oophorectomy on the evolution of the Walker 256 tumor inoculated into the vagina and cervix of female rats. METHODS: Ten Wistar, female rats were used, distributed into two groups with 05 animals each: Tumor group (TG): Rats inoculated with Walker 256 tumor; Oophorectomy group (OG): oophorectomized rats inoculated with Walker 256 tumor. The day before the tumor vaginal inoculation, acetic acid was inoculated into the vaginas of both groups of rats; the following day, the vaginal walls were scarified with an endocervix brush, and then Walker 256 tumor was inoculated. After 12 days, the tumor was removed together with the vagina and uterine horns for macro and microscopic analyses. The data were submitted to statistical analyses. RESULTS: There was no statistical difference between the two groups; however it was observed that the behavior of tumor growth on the OG group presented greater invasion, compromising the uterine horns. CONCLUSION: The results of the study on the GO group presented a macroscopic behavior different from the TG group, however, both of them presented similar development in terms of tumor mass.

OBJETIVO: Estabelecer um modelo de inoculação de Tumor de Walker 256 em vagina e colo de útero de ratas. MÉTODOS: Foram utilizadas 15 ratas fêmeas, virgens, adultas, pesando entre 200-250g, distribuídas em três grupos de estudo com cinco animais cada: grupo A (GA): ratas com tumor de Walker 256 em concentração de 4x10(6) sem ácido acético; grupo B (GB): ratas com tumor de Walker 256 em concentração de 2x10(6) células com ácido acético; grupo C (GC): ratas com tumor de Walker 256 em concentração de 4x10(6) células com ácido acético. No dia anterior à inoculação do tumor, foi realizada a inoculação de 0,3 ml de ácido acético a 10% na vagina das ratas de GB e GC; no dia seguinte, tanto estas como as ratas do grupo GA foram anestesiadas, feita a escarificação da parede vaginal com uma escova de endocérvice e inoculado 0,3ml de tumor na concentração de 4x10(6) células nos grupos GA e GC e 2x10(6) células no grupo GB. Após 12 dias, foi realizada a eutanásia e removido o tumor em bloco com vagina e cornos uterinos para análise, sendo pesado e averiguado seu volume e calculado as relações entre o seu peso e o peso final da rata e o seu volume e o peso final da rata. Os dados foram colhidos e submetidos à análise estatística pelo método ANOVA (um critério). RESULTADOS: A pega em GB e GC foi 100% e em GA 20%. Não houve diferença estatística entre as médias obtidas entre GB e GC. CONCLUSÃO: De acordo com a metodologia utilizada, o modelo de tumor de Walker 256 na vagina apresenta pega de 100% quando associado a ácido acético e não há diferença de comportamento com a inoculação de 4x10(6)ou 2x10(6) células.

PURPOSE: To establish an inoculation model of Walker 256 carcinoma on cervix uteri and vagina of rats. METHODS: Fifteen female rats were used, and assigned to three groups each one with five rats: group A - rats with 4x10(6) cells of Walker 256 carcinoma without acid acetic inoculation; group B - rats with 2x10(6) cells of Walker 256 carcinoma with acid acetic inoculation and group C: rats with 4x10(6) cells of Walker 256 carcinoma with acid acetic inoculation. The day before tumor cells inoculation the rats from groups B and C were anaesthetized with diethylether and 0,3 ml of acetic acid was inoculated into their vaginas. Tumor cell inoculation into the vagina and cervix was done under general anesthesia with diethylether. Then a endocervical brush was used to scrape the vaginal wall and after that 0,3 ml of the liquid containing tumor cells was inoculated on the vagina and cervix. For the tumor analysis, animals were euthanized at day 12 following tumor cell implantation by an excessive inhalation of diethylether. Tumor was resected entirely and weighed and the tumors were then sectioned and counter stained with hematoxylin and eosin for histopathologic evaluation. It was also calculated the percentage of tumor equivalent to the body weight by the formula: P= tumor weight / body weight x 100. Data were analyzed by one-way analysis of variance - ANOVA. P values < 0.05 were taken to indicate statistical significance. RESULTS: Implantation and growth on GB and GC was 100% and on GA 20%. There was no statistical difference between GB and GC averages. CONCLUSION: According to the methods used, the Walker 256 carcinoma inoculation model into vagina and cervix have an implantation and growth rate of 100% when associated with previous acid acetic inoculation and there is no behavioral difference between using 2x10(6) or 4x10(6) cells on its inoculation.
