Abstract Meloidogyne javanica is among the most important nematodes that damage soybean, and although genetic resistance is the ideal control measure, there are few cultivars described as resistant among those recommended for southern Brazil. The objective of this work was to evaluate the reaction of soybean cultivars to M. javanica. The inoculum of nematodes (Est. J3) was obtained from soybean plants and inoculated into tomato plants cultivar “Santa Cruz”. Thirty-seven soybean cultivars widely used in the South, Southeast and Midwest of Brazil were used in the experiment. For each plant a suspension of 5,000 eggs + juveniles of second stage of M. javanica was inoculated into a sterile soil hole in 2-liter pots with six replications. The evaluation of root weight, number of galls, number of nematodes was 60 days after M. javanica inoculation. The results were subjected to analysis of variance, and the averages of each treatment were compared to each other by the Scott-Knott cluster test at 5% probability. Even though M. javanica presented RF> 1.00 in all soybean genotypes tested, different levels of susceptibility were observed. Thus, the lowest reproduction of the root-knot nematode was observed in M 5947 IPRO, HO AMAMBAY IPRO, BMX GARRA IPRO and FPS ATALANTA.

Abstract A study of macro and microfacies, palynoflora and palynofacies of the non-marine Cerro Negro Formation at President Head Peninsula, Snow Island, northwest of the Antarctic Peninsula, was developed. Two assemblages were recognized: Palynofacies assemblage 1 (P1) at the base of the section with a dominance of fern spores and conifer pollen grains, and facies association consisting of a clastic layer, with the predominance of mudstones; and Palynofacies assemblage 2 (P2) at the top of the section, with remarkable abundance of AOM/Pseudoamorphous particles, associated with facies that includes tuffs. The complete section shows in some levels the presence of freshwater algae and translucent phytoclasts. The integrated data characterizes a fluvial-lacustrine environment, what is reinforced by the occurrence of freshwater algae (Botryococcus) in some levels of P1 and P2. We could verify an increase in volcanic activity towards the top of the section that apparently has played an important role in the collapse of the palynoflora. The occurrence of the spore species Muricingulisporis annulatus, Sotasporites elegans, S. triangularis, Foraminisporis wonthaggiensis, and F. asymmetricus in the Cerro Negro Formation allows the correlation with sections in South America and Australia, suggesting an Aptian age for these deposits.

ABSTRACT Paleocene ostracods and planktonic foraminifera from the Maria Farinha Formation, Paraíba Basin, are herein presented. Eleven ostracod species were identified in the genera Cytherella Jones, Cytherelloidea Alexander, Eocytheropteron Alexander, Semicytherura Wagner, Paracosta Siddiqui, Buntonia Howe, Soudanella Apostolescu, Leguminocythereis Howe and, probably, Pataviella Liebau. The planktonic foraminifera are represented by the genera Guembelitria Cushman, Parvularugoglobigerina Hofker, Woodringina Loeblich and Tappan, Heterohelix Ehrenberg, Zeauvigerina Finlay, Muricohedbergella Huber and Leckie, and Praemurica Olsson, Hemleben, Berggren and Liu. The ostracods and foraminifera analyzed indicate an inner shelf paleoenvironment for the studied section. Blooms of Guembelitria spp., which indicate either shallow environments or upwelling zones, were also recorded reinforcing previous paleoenvironmental interpretations based on other fossil groups for this basin.

Resumo O período crepuscular é um dos fatores que pode influenciar na atividade hematofágica dos mosquitos. Muitos desses insetos iniciam ou terminam suas atividades nesse período. O objetivo deste trabalho foi estudar os Culicidae que ocorrem no crepúsculo vespertino em uma área de Floresta Atlântica no oeste de Santa Catarina, sul do Brasil. Além disso, foi analisada a possível influência de fatores abióticos, bem como abundância e riqueza de espécies. Para melhor avaliar a influência do período crepuscular na composição das espécies e na abundância destas, o crepúsculo foi dividido em três períodos: pré-crepúsculo, crepúsculo e pós-crepúsculo. Ao final do estudo foram coletados 984 exemplares distribuídos em 12 gêneros e 23 espécies. Trichoprosopon pallidiventer (Lutz, 1905) (59,76%), Aedes crinifer (Theobald, 1903) (8,13%) e Ae. scapularis (Rondani, 1848) (5,89%) foram as espécies mais abundantes. A maior abundância e riqueza de espécies se deram na primavera. Dentre os três períodos estudados, o pré-crepúsculo apresentou a maior abundância de mosquitos, em contrapartida, o pós-crepúsculo apresentou a menor abundância. Os períodos pré-crepuscular e crepuscular apresentaram maior similaridade entre si com relação à composição das espécies. Relacionando os fatores abióticos e as três espécies mais abundantes, não foi observada correlação significativa nos dados avaliados nos sete e 15 dias anteriores às coletas. Entretanto, a temperatura apresentou uma correlação positiva para estas três espécies. A relação entre as espécies coletadas e a potencial transmissão de agentes etiológicos causadores de doenças foi comentada.

Abstract Crepuscular period is one of the factors that may influence the biting activity of mosquitoes. Many of these insects have a peak activity in this period. The purpose of this study was to investigate the afternoon crepuscular activity of Culicidae in a remaining area of Atlantic Forest in western Santa Catarina, southern Brazil. Moreover, the possible influence of abiotic factors, the abundance and species richness were verified. In order to better analyze the influence of crepuscular period in specific composition and abundance of mosquitoes, the dusk was divided into three periods: pre-sunset, sunset and post-sunset. At the end of the study, nine hundred and eight four specimens distributed in 12 genera and 23 species were collected. Trichoprosopon pallidiventer (Lutz, 1905) (59.76%), Aedes crinifer (Theobald, 1903) (8.13%), Ae. scapularis (Rondani, 1848) (5.89%) were the most abundant species. Spring time presented the greatest abundance and species richness. During the study, among the three periods evaluated, pre-sunset had the greatest abundance and post-sunset the lowest. Pre-sunset and sunset had the greatest similarity between species. Regarding to the abiotic factors evaluated seven and 15 days before sampling, they did not present significant correlation for the three most abundant species. However, temperature had a positive correlation to these species. Moreover, the correlation between collected species and its possible role as vectors of etiological agents of diseases was discussed.

RESUMO: O objetivo deste trabalho foi avaliar a eficiência de extratos vegetais, metaldeído e soluções salinas como alternativas para o controle populacional de Bradybaena similaris e o efeito dos extratos para a redução dos danos sobre Brassica oleracea , em condições de laboratório (Laboratório de Entomologia da Unochapecó, Chapecó, Santa Catarina). O experimento foi conduzido utilizando cinco indivíduos adultos de B. similares para cada um dos nove tratamentos em triplicatas, totalizando 135 caracóis. Os seguintes tratamentos foram testados: extrato de cinamomo ( Melia azedarach ), timbó ( Ateleia glazioveana ), alecrim ( Rosmarinus officinalis ), erva-mate ( Ilex paraguariensis ), metaldeído (3% e 5%), soluções salinas (5% e 10%) e a testemunha (água destilada). Para avaliação dos dados, foi determinada a taxa de sobrevivência de B. similaris a cada 24 horas em um período de quatro dias. Os resultados obtidos indicam que as duas concentrações de metaldeído foram eficientes, a solução salina (10%) apresentou eficiência intermediária, enquanto os demais tratamentos não foram eficazes. Observou-se que o tratamento com extrato de M. azedarach induziu a um consumo maior de B. oleracea , enquanto a solução salina a 10% e os extratos de R. officinalis e I. paraguariensis inibiram o consumo.

ABSTRACT: This study aimed to test the efficiency of plant extracts, metaldehyde and saline solutions, as alternatives to the population control of the snail Bradybaena similaris , and to investigate the effect of the plant extracts in reducing the damage of the snail on Brassica oleracea . The experiments were performed at the Entomology Laboratory of the Universidade Comunitária da Região de Chapecó (Unochapecó), using a random experimental design with nine treatments in triplicate. Five adult individuals of B. similaris were subjected to each trial, totaling 135 snails. The following treatments were tested: cinnamon ( Melia azedarach ), timbó ( Ateleia glazioveana ), rosemary ( Rosmarinus officinalis ), mate herb ( Ilex paraguariensis ), two concentrations of metaldehyde (3% and 5%), two concentrations of salt solution (5% and 10 %), and a control treatment (distilled water). To evaluate the survival of B. similaris it was checked the treatments every 24 hours, over four consecutive days. The results revealed that the two concentrations of metaldehyde were fully efficient, that the saline solution (10%) had and intermediate efficiency, and that all other treatments were not effective. The treatment with the M. azedarach extract induced a higher consumption of B. oleracea , while the saline solution at 10% and the extracts of R. officinalis and I. paraguariensis inhibited leaf consumption.

O objetivo deste estudo foi avaliar a prevalência de dor dentaria, os fatores associados e seu impacto na qualidade de vida relacionada a saúde bucal de crianças pré-escolares. Esse estudo foi realizado em Santa Maria, Brasil, durante o dia nacional de vacinação infantil, e 534 crianças de 0 a 5 anos foram incluídas. As variáveis clinicas incluídas foram carie dental e traumatismo dentário. Um questionário foi respondido pelos pais, fornecendo informações sobre as condições socioeconômicas, uso de serviços odontológicos e dor dentaria. Dor de dente foi coletada através da pergunta: "Seu filho já teve dor de dente - Sim ou Não?". Os dados sobre qualidade de vida relacionada a saúde bucal foram obtidos através da versão brasileira do questionário "Early Childhood Oral Health Impact Scale" (ECOHIS). Modelos multivariáveis de regressão logística foram utilizados para avaliar a associação entre as variáveis preditoras e os desfechos. A prevalência de dor dentaria foi 10,11% (95% IC: 7,55% - 12,68%). Crianças mais velhas apresentaram uma maior chance de ter tido dor dentaria (OR 2,72; 95% IC: 1,01 - 7,56), assim como crianças com experiência de carie (OR 3,43; 95% IC: 1,81 - 6,52). Além disso, as crianças que não tinham visitado o dentista nos últimos 6 meses foram menos propensas a apresentar dor dentária (OR 0,51; 95% IC: 0,28 - 0,95). A presença de dor dentária afeta negativamente a qualidade de vida relacionada a saúde bucal das crianças; aquelas que tiveram dor de dente apresentaram uma maior chance de ter piores impactos nos escores totais do ECOHIS (OR 4,18; 95% IC: 1,76 - 9,95) quando comparadas àquelas que não tiveram dor dentária. O mesmo se pode observar para a seção do questionário correspondente aos impactos na criança (OR 5,54; 95% IC: 2,15 - 14,24. Dor dentaria afeta negativamente a qualidade de vida relacionada a saúde bucal e esta associada com experiência de carie, idade e uso de serviços odontológicos.

The aim of this study was to assess the prevalence of toothache, associated factors and impact of this condition on the Child Oral Health Related Quality of Life (COHRQoL) in preschoolers. The study was carried out in Santa Maria, Brazil, during the National Children's Vaccination Day, and 534 children aged 0 to 5 years were included. Clinical variables included dental caries and dental trauma. A questionnaire was responded by the parents and provided information about several socioeconomic indicators, dental service use and toothache. Toothache was collected by the question: "Has your child ever had a toothache - Yes or no?". Data on COHRQoL were assessed using the Brazilian version of the Early Childhood Oral Health Impact Scale (ECOHIS). Multivariable Logistic regression models were performed to assess the association between the predictor variables and outcomes. The prevalence of toothache was 10.11% (95% CI: 7.55% - 12.68%). Older children had a higher chance of presenting dental pain (OR 2.72; 95% CI: 1.01 - 7.56), as well as children with caries experience (OR 3.43; 95% CI: 1.81 - 6.52). Moreover, children who had not visited the dental service in the last 6 months were less likely to present toothache (OR 0.51; 95% CI: 0.28 - 0.95). The presence of dental pain negatively affects the COHRQoL; those with toothache presented a higher chance of having higher impact on the total scores of ECOHIS (OR 4.18; 95% CI: 1.76 - 9.95) than those without toothache. Similar observation was found for the child section of the questionnaire (OR 5.54; 95% CI: 2.15 - 14.24). Toothache negatively affects COHRQoL and is associated with caries experience, age and use of dental service.

Purposes(a) To externally validate the Crippa and colleagues’ nomograms combining PSA, percentage of positive biopsy cores (PPBC) and biopsy Gleason score to predict organ-confined disease (OCD) in a contemporary sample of patients treated at a tertiary teaching institution. (b) To adjust such variables, resulting in predictive nomograms for OCD and seminal vesicle invasion (SVI): the USP nomograms.Materials and MethodsThe accuracy of Crippa and colleagues’ nomograms for OCD prediction was examined in 1002 men submitted to radical prostatectomy between 2005 and 2010 at the University of São Paulo (USP). ROC-derived area under the curve (AUC) and Brier scores were used to assess the discriminant properties of nomograms for OCD. Nomograms performance was explored graphically with LOESS smoothing plots. Furthermore, univariate analysis and logistic regression models targeted OCD and SVI. Variables consisted of PSA, PPBC, biopsy Gleason score and clinical stage. The resulted predictive nomograms for OCD and SVI were internally validated with bootstrapping and the same abovementioned procedures.ResultsCrippa and colleagues’ nomograms for OCD showed ROC AUC = 0.68 (CI: 0.65-0.70), Brier score = 0.17 and overestimation in LOESS plots. USP nomograms for OCD and SVI showed ROC AUC of 0.73 (CI: 0.70-0.76) and 0.77 (CI: 0.73-0.79), respectively, and Brier scores of 0.16 and 0.08, respectively. The LOESS plots showed excellent calibration for OCD and underestimation for SVI.ConclusionsCrippa and colleagues’ nomograms showed moderate discrimination and considerable OCD overestimation. USP nomograms showed good discrimination for OCD and SVI, as well as excellent calibration for OCD and SVI underestimation.

Doenças neurológicas são prevalentes na sala de emergência (SE). O objetivo deste estudo é comparar a ocorrência de diagnósticos neurológicos entre pacientes jovens e idosos atendidos na SE de um hospital terciário. MÉTODO: Pacientes admitidos na SE que necessitaram avaliação neurológica nas primeiras 24 horas após a admissão foram separados em dois grupos baseados na idade, <;50 anos de idade e >50 anos de idade. RESULTADOS: Doença cerebrovascular foi o diagnóstico mais comum nos pacientes >50 anos (59,6% vs. 21,8%, p<0,01). Convulsões (8,1% vs. 18,6%, p<0,01) e cefaléias primárias (3,7% vs. 114%, p<0,01) foram mais frequentes no grupo <;50 anos. CONCLUSÃO: O presente estudo demonstrou que esses três diagnósticos neurológicos representam a maioria das avaliações neurológicas na SE. Diretrizes nacionais para os profissionais emergencistas que tratam estas doenças devem ser incluídos na prática clínica e no treinamento médico.

Neurological diseases are prevalent in the emergency room (ER). The aim of this study was to compare the neurological diagnoses between younger and older patients evaluated in the ER of a tertiary care hospital. METHOD: Patients admitted to the ER who required neurological evaluation in the first 24 hours were separated into two groups based on age, <;50 years old and >50 years old. RESULTS: Cerebrovascular disease (59.6% vs. 21.8%, p<0.01) was most frequent in the >50 years old group. Seizures (8.1% vs. 18.6%, p<0.01) and primary headache (3.7% vs. 11.4%, p<0.01) were most frequent in the <;50 years old group. CONCLUSION: The current study demonstrated that these three neurological diagnoses represented the majority of the neurological evaluations in the ER. National guidelines for ER teams that treat these prevalent disorders must be included in clinical practice and training.

OBJECTIVES: urinary fistula is a morbid complication after renal transplantation leading to graft losses and patient death. We review and update our data on urinary fistula after renal transplantation and the outcome after surgical and conservative management. MATERIALS AND METHODS: the charts of 1046 renal transplants were reviewed. Transplants were performed through an extended inguinotomy; vascular anastomoses to the iliac vessels and urinary reconstruction accomplished through the Gregoir technique. Fistulae were diagnosed by urinary leaks through the incision or by the occurrence of a collection in the iliac fossa. Patient was treated surgically or conservatively according to the characteristics of the fistula and patient clinical status. RESULTS: Thirty one fistulae were diagnosed (2.9%). Twenty nine leaks due to ureteral necrosis and 2 due to reimplantation fault. The incidence of leaks among cadaver and live donor transplants was 3.22% and 2.63%, respectively (p = 0.73). Among diabetic and non diabetic patients the incidence of urinary leaks was 6.4% and 2.6%, respectively (p = 0.049). Treatment consisted in anastomosis of the graft ureter or pelvis with the ureter of the recipient in 17 cases with success in 13 (76.5%). Prolonged bladder drainage was employed in 7 cases and the fistula healed in 4 (57%). Ureteral reimplantation was performed in 3 cases and did not work in any of them. Ureteral ligature plus nephrostomy was employed in two cases and worked in one (50%). Percutaneous nephrostomy and ureteral stenting with double J catheter were employed in one case each and worked in both. CONCLUSIONS: The anastomosis of the graft ureter with the ureter of the recipient is a good method for treating urinary fistulae after renal transplantation when local and systemic conditions are good. Ureteral ligature associated to nephrostomy should be applied in cases of unfavorable local conditions or clinically unstable patients.

INTRODUCTION: Renal transplantation with multiple arteries appears, in literature, associated to a major index of surgical complications. This study compared the surgical complications and short-term outcome renal transplants with multiple arteries and single artery grafts. MATERIALS AND METHODS: The data of 64 renal transplants with multiple arteries performed between January 1995 and December 1999 were compared to the ones of 292 transplants with single renal artery. The aspects analyzed were number of arteries of the graft, donor type, vascular reconstruction technique, the occurrence of surgical complications, the incidence of delayed graft function, graft function 1 month after transplantation, graft loss and the patients' deaths. RESULTS: The incidence of surgical complications in grafts with multiple arteries and single renal artery was respectively: vascular - 3.1% and 3.1%; urological - 6.3% and 2.7% and other surgical complications - 15.6% and 10.6%, respectively. The incidence of lymphoceles was 3.1% in grafts with a single artery and 12.5% in grafts with more than 1 artery (p = 0.0015). The incidence of delayed graft function in grafts with multiple arteries and with a single renal artery was respectively 35.1 and 29.1% (p = 0.295). Mean serum creatinine at the 30th postoperative day was 2.46 and 1.81 in grafts with multiple and with 1 artery, respectively (p=0.271). CONCLUSIONS: Kidney transplantation using grafts with single and multiple arteries present similar indexes of surgical complications and short-term outcome; lymphoceles were more frequent among grafts with multiple arteries.

This paper discusses the electrochemical behavior of copper, nickel and a copper/nickel alloy in aerated aqueous 0.10 and 1.0 mol L-1 sodium acetate. The data obtained from different electrochemical techniques were analyzed to determine the influence of Ni and Cu on the electrochemical processes of the alloy electrode. The shapes of the potentiodynamic I(E) curves of the alloy were found to be quite similar to those of the Ni voltamograms. Although the anodic current densities of Ni and the alloy increased with greater concentrations of acetate, the opposite effect occurred in Cu. The impedance measurements taken at the open circuit potential revealed that the polarization resistance (R P) of the electrodes decreased in the following order: Ni > Alloy > Cu. With increasing concentrations of acetate, the R P of the alloy and the Cu increased while that of the Ni electrode decreased.
