Introdução: Diferentes técnicas cirúrgicas foram desenvolvidas para a redução do volume glandular e para a correção da ptose mamária com o objetivo de obter resultados eficientes e de qualidade com o menor número de complicações possível. Este artigo descreve a técnica de mastopexia idealizada pelo Dr. Roberto Antonio Barjaz Millan e a avaliação do nível de satisfação das mulheres após o procedimento. Métodos: Trata-se de um estudo transversal, observacional e analítico desenvolvido a partir da análise da técnica de mastopexia na redução mamária e na correção de ptose mamária padronizada pelo Dr. Millan, realizado no Setor de Cirurgia Plástica do Centro Universitário Saúde ABC. Participaram do estudo 20 mulheres com ptose mamária grau II e III, segundo classificação de Regnault, ou hipertrofia mamária, definida pelos critérios de Sacchini et al. e de Franco & Rebello, ainda não submetidas a cirurgia e 20 mulheres previamente submetidas a mastopexia pela técnica de Millan, com idades entre 18 e 60 anos. Para análise do nível de satisfação após o procedimento, foi aplicado o questionário BREAST-Q®. Resultados: Não houve diferenças significantes das mulheres que fizeram a cirurgia (grupo pós-cirúrgico) quando comparadas às que não fizeram cirurgia (grupo controle) em relação às variáveis idade (p=0,357), Índice de Massa Corporal (p=0,695), grau de hipertrofia (p=0,799) e grau de ptose mamária (p=0,391). Em relação às variáveis de satisfação com mamas, psicossocial, sexual, físico, todas as pacientes submetidas a cirurgia apresentaram valores maiores comparados aos valores obtidos nas pacientes do grupo sem cirurgia (p<0,009). Conclusão: A técnica de mastopexia idealizada pelo Dr. Millan apresenta resultados que foram considerados satisfatórios pelas pacientes avaliadas.

Introduction: Different surgical techniques were developed to reduce glandular volume and correct breast ptosis, with the objective of efficient and quality results for the patients and with the fewest possible complications. This study describes the treatment technique standardized by Dr. Roberto Millan and the level of women's satisfaction after performing the procedure. Methods: This is a cross-sectional, observational and analytical study carried out from the analysis of the breast treatment technique standardized by Dr. Millan performed at the Plastic Surgery Sector of Centro Universitário Saúde ABC. The study included 20 women with grade II and III breast ptosis, according to Regnault's classification, or breast hypertrophy, defined by the criteria of Sacchini et al. and by Franco & Rebello; and 20 women previously submitted to mastopexy or reduction mammoplasty using the Millan technique, aged between 18 and 60 years.

Ascophyllum nodosum Extract (SealicitTM) Boosts Soybean Yield Through Reduction of Pod Shattering-Related Seed Loss and Enhanced Seed Production.

Soybean is one of the most valuable commercial crops because of its high protein, carbohydrate, and oil content. The land area cultivated with soybean in subtropical regions, such as Brazil, is continuously expanding, in some instances at the expense of carbon storing natural habitats. Strategies to decrease yield/seed losses and increase production efficiency are urgently required to meet global demand for soybean in a sustainable manner. Here, we evaluated the effectiveness of an Ascophyllum nodosum extract (ANE), SealicitTM, in increasing yields of different soybean varieties, in two geographical regions (Canada and Brazil). In addition, we investigated the potential of SealicitTM to reduce pod shattering at the trials in Brazil. Three different concentrations of SealicitTM were applied to pod shatter-susceptible (SS) UFUS 6901 and shatter-resistant (SR) UFUS 7415 varieties to assess their impact on pod firmness. SS variety demonstrated a significant decrease in pod shattering, which coincided with deregulation of GmPDH1.1 and GmSHAT1-5 expression, genes that determine pod dehiscence, and higher seed weight per pod. SealicitTM application to the SR variety did not significantly alter its inherent pod shatter resistance, but provided higher increases in seed yield at harvest. This yield increase maybe associated with to other yield components stimulated by the biostimulant. This work demonstrates that SealicitTM, which has previously been shown to improve pod firmness in Arabidopsis and selected commercial oilseed rape varieties through IND gene down-regulation, also has the potential to improve pod resistance and seed productivity in soybean, a member of the legume family sharing a similar strategy for seed dispersal.

Selection of lineages, genetic parameters, and correlations between soybean characters / Seleção de linhagens, parâmetros genéticos e correlações entre caracteres em soja

Soybean has great economic importance in the world accordingly, this legume has been exploited in breeding programs aiming to provide cultivars with extensive grain yield, tolerant to pests and diseases, and adapted to different soil and climatic conditions. Therefore, the objectives of this study were to evaluate genetic parameters and correlations between soybean traits to select lineages to increase yield and improve agronomic traits. Experiments were carried out on the Capim Branco farm, of the Federal University of Uberlândia, harvest in 2016/2017. Fifteen morph-agronomic traits were assessed on twenty-two genotypes in a randomized complete block design with three replicates. Agronomic traits related to cycle, height, number of nodes and total pods have shown coefficients of genotypic determination higher than 70%. In addition, coefficients of variation of the number of days to the flowering and number of days to maturity were equal to 3.79% and 4.87%, respectively, indicating high homogeneity of data and low random variation. Among evaluated traits, ten have presented the ratios between the coefficient of genetic variation (CVg) and coefficient of environmental variation (CVe) above one, demonstrating high success likelihood in the selection of these traits. Fifteen genotypes have presented grain yield above the national average of the 2016/2017 harvest, which was 2882 kg h-1. Significant phenotypic correlations between traits ranged from -0.49 to 0.89, however genotype correlation was higher than the phenotypic ones, indicating that genetic factors have contributed more than the environmental factors. Traits related to cycle, height, and the number of nodes in the main stem have presented measures of H² and CVg / CVe with extensive magnitudes, evidencing the possibility of selection lineages having superior traits in the Soybean Breeding Program of the Federal University of Uberlândia. To increasing grain yield, the traits Number of pods of three grains and the Total number of pods were identified as appropriated to indirect selection based on the phenotypic and genotypic correlations. The 2lP14, B2P1, B2P28, B1P33 and 2AP11 lineages stand out as superior genotypes to direct selection.

A soja é uma cultivar de grande importância econômica mundial e por esse motivo essa leguminosa é explorada nos programas de melhoramento, que visam disponibilizar cultivares de alta produtividade de grãos, tolerantes a pragas e doenças e adaptadas à diferentes condições edafoclimáticas. Os objetivos desse trabalho foram selecionar linhagens, avaliar parâmetros genéticos e correlações entre caracteres de soja. O experimento foi conduzido na área experimental da Fazenda Capim Branco pertencente à Universidade Federal de Uberlândia na safra de 2016/2017. Avaliaram-se 22 genótipos em delineamento deblocos completos casualizados com três repetições para 15 caracteres morfo-agronômicos. Os caracteres agronômicos relacionados ao ciclo, altura, número de nós e vagens totais tiveram coeficiente de determinação genotípico superiores a 70%. Obteve-se coeficiente de variação para o caráter número de dias para o florescimento igual a 3,79% e para o caráter número de dias para maturação, 4,87%, indicando maior homogeneidade entre os dados e baixa variação ao acaso. Dos caracteres avaliados, dez apresentaram razão entre coeficiente de variação genético e coeficiente de variação ambiental superiores a um, demonstrando oportunidade de sucesso no processo de seleção para esses respectivos caracteres. 15 genótipos obtiveram produtividade de grãos superior à média nacional de safra 2016/2017, isto é, a 2882 kg h-1. As correlações fenotípicas entre caracteres que foram significativas oscilaram de -0,49 a 0,89, cujas estimativas de correlação genotípica foram superiores à correlação fenotípica, indicando que os fatores genéticos contribuíram mais que os ambientais. Os caracteres relacionados ao ciclo, altura e número de nós na haste principal, tiveram H² de elevada magnitude e altas estimativas na razão CVg/CVe, evidenciando a possibilidade de seleção de linhagens superiores no Programa de Melhoramento de Soja da Universidade Federal de Uberlândia. Considerando o caráter produtividade de grãos, foi possível identificar número de vagens de três grãos e número total de vagens para a seleção indireta, com base nas correlações fenotípicas e genotípicas. As linhagens 2lP14, B2P1, B2P28, B1P33 e 2AP11 destacam-se como genótipos superiores na seleção direta.

Papillomavirus infections in the oral and genital mucosa of asymptomatic women

Abstract Human papillomavirus (HPV) has been found in several regions of the body, including the oral cavity. Recently, this virus has been associated with oropharyngeal cancer, but little is known about HPV transmission to the oral cavity. We carried out a study to investigate concurrent oral and cervical infections in 76 asymptomatic women attending a healthcare program. Demographic and behavior data were obtained through a structured questionnaire. Oral and cervical mucosa scrapings were collected and stored for DNA extraction. HPV DNA amplification was performed by polymerase chain reaction assay (PCR) using both primers My09/My11 and FAP59/64, followed by HPV typing with restriction fragment length polymorphism analysis (RFLP) and sequencing. The data collected revealed no risk factors for HPV infection in these 76 women. HPV prevalence of 9.2 and 5.3% was found in cervical and oral mucosa, respectively. Concurrent infections by discordant types were detected in one case only. Sequencing procedures allowed us to detect a new putative HPV 17 subtype from the Betapapillomavirus genus. Our results support the view that cervical and oral HPV infections are independent events. The observed low prevalence of both oral and cervical HPV infections could be associated with attendance in a healthcare program.

Estudo comparativo da variabilidade de posição dos terceiros molares retidos em pacientes adolescentes e adultos jovens / Comparative study of variability of position of impacted third molars patients in teens and young adults

O objetivo do presente trabalho foi determinar, através da avaliação de radiografias panorâmicas, a prevalência da posição dos terceiros molares, definindo as posições mais freqüentes e sua distribuição entre os gêneros. De uma amostra de 279 radiografias panorâmicas de pacientes atendidos no Serviço de Cirurgia e Traumatologia Bucomaxilofacial da FO-PUCRS, no período compreendido entre março e setembro de 2006, foram selecionadas 100 radiografias que obedeciam os seguintes critérios de inclusão: presença de segundo molar na hemiarcada e presença de terceiro molar retido na hemiarcada. Das 100 radiografias panorâmicas 42% apresentavam todos os terceiros molares; 15% três terceiros molares, 31% dois terceiros molares, 9% um terceiro molar. Apenas 3% mostrou agenesia de todos os terceiros molares. Concluiu-se que a posição mais prevalente do terceiro molar retido, em ambos os gêneros, foi a mésio-angulada, seguida pelas posições, vertical, disto-angulada e, finalmente a horizontal. A freqüência da posição mésio-angulada foi maior nos terceiros molares inferiores e apresentou-se ligeiramente maior no gênero masculino (44,8%).

The aim of this study was establish the prevalence of the position of the third molar. This objective was accomplished using panoramic x-ray. Our variables in concern were the most frequent position and the distribution between genders of this tooth. These x-rays were selected by the following inclusion criteria: existence of the second molar in the hemi-arcade and presence of the non-erupted third molar in the hemi-arcade. We used 100 x-rays, which 42% showed all third molars, 15% showed three, 31% showed two, 9% showed one and 3% showed no third molars. As a result, we found that in all third molars, the most frequent position was the mesio-angular in both genders. We also found that the most frequent position of non-erupted third molar, in both genders, was a mesio-angular, followed by the positions vertical, disto-angular and horizontal.

Descompressão como tratamento inicial de tumor odontogênico ceratocístico: revisão de literatura

O Tumor Odontogênico Ceratocístico (TOC) é uma lesão intraóssea de origem dos remanescentes da lâmina dental na mandíbula e maxila, e possui altos índices de recidiva. Devido ao comportamento agressivo dos TOCs, diversas modalidades terapêuticas têm sido empregadas ao longo dos anos, tanto técnicas radicais, como técnicas conservadoras, ambas com a finalidade de tratamento dos tumores, seja definitivo ou como etapa preliminar. Em busca de procedimentos menos invasivos e ao mesmo tempo apresentando baixos índices de recidiva, o presente estudo tem como objetivo aprofundar e atualizar os conhecimentos sobre o TOC, dando ênfase à técnica de descompressão como alternativa inicial para o tratamento dos casos diagnosticados de TOCs, abordando as vantagens, desvantagens, indicações e contra-indicações desta terapêutica. O tratamento do TOC, através da técnica de descompressão, mostrou-se ter elevada taxa de sucesso, baixa mortalidade, e preservando estruturas anatômicas importantes, conduzindo à um resultado satisfatório e menos traumático para o paciente.
