Seletividade de herbicidas aplicados em pré-emergência sobre cultivares de batata

O presente trabalho foi realizado na Estação Experimental Agrícola da BASF S.A., situada na rodovia SP 310, km 144, no município de Santo Antonio da Posse-(SP), em área de Latossolo Vermelho distrófico com textura média. Quatro experimentos foram desenvolvidos com o objetivo de avaliar a seletividade dos herbicidas dimethenamid, metribuzin e linuron, aplicados em diferentes doses, na condição de pré-emergência, sobre as características de produção e qualidade dos tubérculos de quatro cultivares de batata (Solanum tuberosum L.). Utilizou-se, em todos os experimentos, o delineamento experimental de blocos ao acaso, com cinco repetições e parcelas de 21 m² (3 x 7 m). Os tratamentos utilizados foram: testemunha capinada, dimethenamid nas doses de 0,75, 1,50 e 3,00 kg ha-1, metribuzin a 0,48 e 0,72 kg ha-1 e linuron a 1,50 e 2,00 kg ha-1. Foram realizadas três avaliações visuais de fitotoxicidade aos 24, 31, e 42 dias após a aplicação (DAA). A severidade das injúrias visuais verificadas nas plantas das diferentes cultivares de batata foi dependente do herbicida, da dose aplicada e da cultivar utilizada. O herbicida dimethenamid, na dose de 3,00 kg ha-1, foi o tratamento que proporcionou as maiores porcentagens visuais de área foliar injuriada, no entanto tais sintomas desapareceram completamente aos 42 DAA. Nenhum tratamento com herbicida interferiu negativamente na produção de tubérculos, na massa seca dos tubérculos e no tamanho final dos tubérculos colhidos.

Biomass and Stand Characteristics of a Highly Productive Mixed Douglas-Fir and Western Hemlock Plantation in Coastal Washington

Aboveground biomass predictive equations were developed for a highly productive 47-year-old mixed Douglas-fir and western hemlock stand in southwest Washington State to characterize the preharvest stand attributes for the Fall River Long-Term Site Productivity Study. The equations were developed using detailed biomass data taken from 31 Douglas-fir and 11 western hemlock trees within the original stand. The stand had an average of 615 live trees per hectare, with an average dbh of 35.6 cm (39.1 cm for Douglas-fir and 33.3 cm for western hemlock) and an average total tree height of 31.6 m (32.8 m for Douglas-fir and 30.2 m for western hemlock). Equations developed were of the form In Y = b(1) + b(2) In dbh, where Y = biomass in kg, dbh = diameter in cm at 1.3 m height, b(1) = intercept, and b(2) = slope of equation. Each tree part was estimated separately and also combined into total aboveground biomass. The total aboveground biomass estimation equations were In Y = -0.9950 + 2.0765 In dbh for Douglas-fir, and In Y = -1.6612 + 2.2321 In dbh for western hemlock. The estimate of the aboveground live-free biomass was of 395 Mg ha(-1) (235 Mg ha(-1) for Douglas-fir and 160 Mg ha(-1) for western hemlock), with 9.5, 29.3, 12.9, 308, and 32.7 Mg ha(-1) in the foliage, live branches, dead branches, stem wood, and stem hark, respectively. When compared with biomass estimates from six other studies, ranging in age from 22 to 110 years and from 96.3 to 636 Mg ha(-1), the biomass of the Fall River site was relatively high for its age, indicating very high productivity.

Paracoccidioidomycosis

Paracoccidioidomycosis is an endemic systemic mycosis that predominates in southern Mexico, parts of Central America, and South America. It is caused by a dimorphic fungus and is generally acquired through the lungs, from where it disseminates. Paracoccidioidomycosis has different clinical manifestations that require differentiation with tuberculosis, Hodgkin disease, several systemic and subcutaneous mycoses, and squamous cell carcinoma. Diagnosis is made by finding the organism in a biopsy specimen and isolating it in fungal culture. Treatment includes sulfamethoxazole-trimethoprim for mild forms and itraconazole for moderate cases. Fluconazole and voriconazole can be used for meningeal involvement, and amphotericin B is indicated for severe disease. (C) 2012 Elsevier B.V. All rights reserved.

Acidente com material perfurocortante entre profissionais de enfermagem de um hospital universitário

Os riscos ocupacionais a que os profissionais da equipe de enfermagem estão sujeitos no desempenho de suas funções são consideráveis. Assim estabeleceu-se como objetivo deste estudo analisar os acidentes perfurocortantes no período de 2002 a 2006, envolvendo a equipe de enfermagem de um hospital universitário, para compreender o contexto em que ocorrem. A utilização destas informações pode ser ferramenta de prevenção. Estudo descritivo, retrospectivo quantitativo e qualitativo. Na análise quantitativa foi utilizada estatística descritiva e na qualitativa o discurso do sujeito coletivo. Por meio das fichas de notificação do Núcleo de Vigilância Epidemiológica do Hospital, foi possível identificar acidentes do gênero no período pesquisado. Entrevistas foram direcionadas às vítimas de acidentes que tiveram como paciente-fonte portador de Síndrome da Imunodeficiência Adquirida/ Vírus da Imunodeficiência Humana, hepatite B e C. Os achados demonstraram que ainda persiste um grau significativo do desconhecimento ou banalização dos acidentes entre profissionais da saúde.

Gonadic Sperm Reserve in Buffaloes Created under Tropical Conditions

The objective of the present study was quantifying the spermatic production per gram and daily rate of the testicular parenchyma. Testis of 12 crossbred Murrah buffaloes aged 24 to 48 months created under extensive conditions in the State of São Paulo/Brazil were analyzed. Animals were divided into groups based on the testicular shape (long and long-moderate) and testicular sides (right and left) and the studied parameters were: length and testicular width, weight and volume of the albuginea and mediastinum and net weight of the testicular parenchyma, gonadic sperm reserves, spermatic production/g of testicular parenchyma, daily spermatic production/g, total daily spermatic production, resulting into the values: 8.16 +/- 0.87 and 4.29 +/- 0.50 cm; 9.09 +/- 1.91 g and 8.77 +/- 1.88 mL; 0.97 +/- 0.39 g and 0.90 +/- 0.38 mL; 112.91 +/- 18.85 g; 14.32 x 10(9) +/- 0.15; 13.42 x 10(6) +/- 0.17; 27.40 x 10(6) +/- 0.35 and 2.92 x 10(9) +/- 0.30, registering no difference between right and left testis in relation to the parameters (P>0.05). There was no relation between testicular biometry and spermatic production (P>0.05). According to the obtained values, all animals were considered sexually mature and presented an efficient spermatic production per gram of testicular parenchyma and total daily production.

Neospora caninum infection dynamics in dairy cattle

Neospora caninum is considered in many countries as one of the key abortion agents in cattle. This study aims to investigate the parasite behavior in dairy cattle in the municipality of Avar,, SP, Brazil, where abortions frequently occur. An ELISA was performed to compare two samplings on a total of 615 animals; tests were performed in the same herds with a gap of 3 years. An increase in the percentage of reactive animals was observed, ranging from 21.6% at the first sampling to 38.9% at the second sampling. of the 176 animals tested at both samplings, 61.93% retained a non-reactive status, 15.9% retained a reactive status, 19.88% switched from non-reactive to reactive and 2.27% switched from reactive to non-reactive. of the 100 animals with reproductive disturbances, 50% presented anti-Neospora antibodies, thereby indicating the presence of the protozoa. When comparing cows and their respective female offspring, a predominance of horizontal infection was observed. Moreover, considering the significant percentage of animals that switched from non-reactive to reactive and the abundant presence of dogs among the herds, the N. caninum transmission may be attributed to presence of carnivores.

Molecular and functional characterization of a new non-hemorrhagic metalloprotease from Bothrops jararacussu snake venom with antiplatelet activity

BjussuMP-II is an acidic low molecular weight metalloprotease (Mr similar to 24,000 and pI similar to 6.5), isolated from Bothrops jararacussu snake venom. The chromatographic profile in RP-HPLC and its N-terminal sequence confirmed its high purity level. Its complete cDNA was obtained by RT-PCR and the 615 bp codified for a mature protein of 205 amino acid residues. The multiple alignment of its deduced amino acid sequence and those of other snake venom metalloproteases showed a high structural similarity, mainly among class P-I proteases. The molecular modeling analysis of BjussuMP-II showed also conserved structural features with other SVMPs. BjussuMP-II did not induce hemorrhage, myotoxicity and lethality, but displayed dose-dependent proteolytic activity on fibrinogen, collagen, fibrin, casein and gelatin, keeping stable at different pHs, temperatures and presence of several divalent ions. BjussuMP-II did not show any clotting or anticoagulant activity on human citrated plasma, in contrast to its inhibitory effects on platelet aggregation. The aspects broached, in this work, provide data on the relationship between structure and function, in order to better understand the effects elicited by snake venom metalloproteases.
