Resumo Myrciaria glomerata O. Berg. (Myrtaceae) é uma frutífera nativa da Mata Atlântica com potencial alimentício, medicinal e ecológico, mas com baixa taxa de germinação. Objetivou-se com este trabalho avaliar diferentes métodos na superação da dormência de sementes e no vigor de plântulas de M. glomerata. Foram realizados dois experimentos. No experimento 1, foram testados sete tratamentos: controle; imersão em água a 100 ºC por 30 segundos; imersão em ácido sulfúrico concentrado (H2SO4) por 1 e 5 minutos; imersão em solução aquosa de ácido giberélico (AG3) 250 e 500 mg L-1 e imersão em solução aquosa com 5 mL de Stimulate® kg-1 de sementes. No experimento 2, foram testadas sete doses de Stimulate®: 0; 5; 10; 15; 20; 25 e 30 mL kg-1 de sementes. A imersão das sementes em 250 e 500 mg L-1 AG3 contribui na velocidade de germinação e maior comprimento, massas frescas e secas, em comparação às do controle e aos outros métodos testados. A imersão em água a 100 ºC e em H2SO4 não é recomendada para M. glomerata. As doses de 20 a 25 mL de Stimulate® kg-1 de sementes proporcionam incremento para todas as características anali-sadas. Imersão em AG3, na concentração de 250 mg L-1, e doses de 15 a 25 mL de Stimulate® kg-1 de sementes são eficientes para a superação da dormência de sementes e o vigor de plântulas de M. glomerata.

Abstract Myrciaria glomerata O. Berg. (Myrtaceae) is a fruit tree native to the Brazilian Atlantic Forest with potential for use as food and medicine, besides having good ecological potential. However, this species is limited by low germination rates. Thus, this study aimed to evaluate different methods to overcome dormancy in seeds of M. glomerata and to improve seedling vigor. For this, two experiments were conducted. In Experiment 1, seven treatments were tested: a control treatment, immersion in water at 100 ºC for 30 seconds, immersion in concentrated sulfuric acid (H2SO4) for 1 and 5 minutes, immersion in an aqueous solution of gibberellic acid (GA3) at the concentrations of 250 and 500 mg L-1 for 24 h, and seeds homogenized with an aqueous solution of Stimulate® at a concentration of 5 mL kg-1 seed. In Experiment 2, six doses of Stimulate® were tested: 0, 5, 10, 15, 20, 25, and 30 mL kg-1 seed. The immersion of seeds in 250 and 500 mg L-1 GA3 contributes to increase germination rates, seed length, fresh mass, and dry mass compared to the control and the other methods tested. Immersions in water at 100 ºC and in H2SO4 are not recommended for M. glomerata. The treatment with Stimulate® at 15–25 mL kg-1 seed increased all characteristics analyzed. Immersion in 250 mg L-1 GA3 and Stimu-late® at 20–25 mL kg-1 seed efficiently stimulated seeds to overcome dormancy in M. glomerata, as well as improved seedling vigor.

Abstract This study aimed to assess trainee perceptions regarding the usefulness of an intensive hands-on minimally invasive surgery (MIS) training, as well as the subsequent implementation experience. An online questionnaire was emailed to 110 small animal veterinarians who attended the course between 2007 and 2017. The questionnaire comprised three sections: general attendee information, questions pertaining to the received laparoscopic and thoracoscopic training, and finally enquiries on cumulative post-training and current MIS practice. Forty-five veterinarians answered the questionnaire. Most respondents had prior laparoscopy and/or thoracoscopy experience (95.2 %), but close to half (46.7 %), modified their clinical practice as a result of the training. Seventy-five percent of the totally inexperienced participants started practicing MIS within two years of attending the course. A large proportion of respondents indicated their need for additional training for more advanced laparoscopy (71.1%) and thoracoscopy (77.8%) procedures. Accordingly, the main difficulty found by respondents regarding MIS implementation was insufficient training (37.8%). The most frequently encountered difficulty during procedures was bleeding (46.7%), while the most feared complication was related to anesthesia (31.1%). Ovariectomy and ovariohysterectomy were the most frequently performed minimally invasive procedures in trainee working centers. MIS training promotes the introduction of laparoscopy and thoracoscopy into clinical practice and expands the type of surgeries performed with these approaches. Nonetheless, a single intensive program does not comply with the diverse training needs of small animal practitioners.

ABSTRACT Zika virus (ZIKV) clinical presentation and frequency/duration of shedding need further clarification. Symptomatic ZIKV-infected individuals identified in two hospitals in Sao Paulo State, Brazil, were investigated regarding clinical characteristics, shedding in body fluids, and serodynamics. Ninety-four of 235 symptomatic patients (Site A: 58%; Site B: 16%) had Real-Time PCR-confirmed ZIKV infection; fever, headache and gastrointestinal symptoms were less frequent, and rash was more frequent compared to ZIKV-negative patients. Real-Time PCR in serum had worse performance compared to plasma, while urine had the highest sensitivity. Shedding in genital fluids and saliva was rare. IgM positivity was the highest <14 days after the symptoms onset (86%), decreasing >28 days (24%); IgG positivity increased >14 days (96%) remaining positive in 94% of patients >28 days. ZIKV prevalence varied importantly in two neighboring cities during the same transmission season. Urine Real-Time PCR can improve diagnostic sensitivity; serum testing is less useful. Accurate serological tests are needed to improve diagnosis and surveillance.

Este trabalho teve como objetivo avaliar o desenvolvimento e a produção de seis genótipos de bananeira nas condições bioclimáticas do Sudoeste Goiano. O experimento foi conduzido em área experimental na Fazenda Aroeira localizada no Município de Jataí-GO, microrregião do sudoeste Goiano. Em dois ciclos de produção, foram avaliados os genótipos 'Caipira' (AAA), 'Thap Maeo' (AAB), 'FHIA-01' (AAAB), 'FHIA-21' (AAAB), 'FHIA-18' (AAAB), descritos pela Embrapa como resistentes à Sigatoka, e a 'Terra' (AAB - subgrupo Terra), cultivada tradicionalmente pelos produtores da região. O experimento foi montado num delineamento experimental em blocos casualizados, com seis tratamentos (genótipos) e seis repetições, em condições de sequeiro com espaçamento de 3 x 2 m. A caracterização do desenvolvimento e do rendimento dos genótipos foi realizada com as seguintes avaliações: NDPC - número de dias do plantio à colheita; MC - massa do cacho (kg); NP - número de pencas; CE - comprimento do engaço (cm); Ø - diâmetro do engaço (mm); ME - massa do engaço (kg); Ø2ªP - diâmetro do fruto da segunda penca (mm); C2ªP - comprimento do fruto da segunda penca (mm); M2ªP - massa da segunda penca (kg); N2ªP - número de frutos da segunda penca; ØPSFL - diâmetro do pseudocaule na floração (cm), NFC - número de folhas na colheita, e APF - altura da planta na floração. Observou-se um regime hídrico bem definido, com uma estação chuvosa de outubro a março e um período seco de abril a setembro. Considerando que diferentes ambientes influenciam no desempenho dos genótipos de banana e na manifestação dos caracteres, o bom desenvolvimento desses genótipos indica a adaptação às condições climáticas da região. De acordo com os dados de produção do segundo ciclo, os genótipos 'FHIA-18', 'FHIA-01' e 'FHIA-21' apresentaram características agronômicas favoráveis e podem ser indicados como alternativas de cultivo aos produtores da região. As baixas temperaturas e a altitude contribuíram para o alongamento do ciclo em todas as cultivares, com maiores ciclos produtivos para 'FHIA-21' e 'Terra'.

This research aimed the evaluation of growing and yield of six banana genotypes at the bioclimatic conditions of the Southwest region of the State of Goiás. Field trials were carried out at Fazenda Aroeira, a commercial farm located in Jataí, under the Southwest micro-region of the State of Goiás, without the use of supplemental irrigation. Data were collected in two production cycles and the genotypes evaluated were 'Caipira' (AAA), 'ThapMaeo' (AAB), 'FHIA-01' (AAAB), 'FHIA-21' (AAAB), 'FHIA-18' (AAAB), described as resistant to Black Sigatoka, and 'Terra' (AAB - subgroupTerra), traditionally cultivated by surrounding growers. It was used a randomized block design with six treatments (genotypes) and 6 repetitions (plots). Plants were spaced 3 meters between rows and 2 meters between plants within a row. Growing and yield characterization of the six genotypes were done by the following evaluations: number of days from planting to harvesting, bunch weight, hands number, stem length, stem diameter, stem weight, diameter of the second hand fruit, length of the second hand fruit, second hand weight, number of fruits at the second hand, pseudostalk diameter at flowering, leaf number at harvesting and plants height at flowering. It was observed a well defined water regime, with a rainy season from August to March and a dried season from April to September. Considering that different environments influences genotypes performance and characters expression, the good development of such genotypes suggests their adaptation to the climatic conditions of Southwest region of the state of Goiás. According to data obtained at the second growing cycle, the genotypes 'FHIA-18', 'FHIA-01' and 'FHIA-21' presented favorable agronomic characteristics, and they can be indicated as alternative cultivars to local growers. The low temperatures and altitude contributed for longer growing cycle for all genotypes, with the longest ones observed for 'FHIA-21' and 'Terra'.
