Crop optimization and pre-steps standardization to get a Bipolaris euphorbiae-based bioherbicide

Making bioproducts available to the market requires finding appropriate processes for mass production and formulation of biological agents. This study aimed at evaluating the Bipolaris euphorbiae production in a solid medium (fermentation in solid substrate) and in a biphasic system (growth in a liquid medium followed by growth in a solid medium), as well as determining the processes for collecting and drying conidia, under laboratory conditions. The influence of the incubation period and inoculum quantity were also investigated. The conidia were dried by using an oven (30ºC, 35ºC, 40ºC, 45ºC, 50ºC, 55ºC and 60ºC), and laminar flow, continuous air flow and aseptic chamber at room temperature. Dry conidia were obtained by sieving and grinding in a ball mill, hammer mill or grain grinder. The conidia viability and sporulation efficiency were evaluated in the solid medium and in the biphasic system. For growth period, the best sporulation on solid medium was obtained after 10 days of incubation, reaching 8.3 x 10(7) conidia g-1 of substrate. The biphasic system did not increase the B. euphorbiae sporulation (4.5 x 10(7) conidia g-1 of substrate), after 14 days, and the amount of liquid inoculum used in this system was not an important factor for increasing its production. The continuous air flow and laminar flow preserved the conidial viability (94.6% and 99.1%, respectively), while promoting a great moisture loss (62.6% and 54.0%, respectively). All the grinding processes reduced the conidia germination (86.2%, 10.5% and 12%, respectively), while sieving allowed the collecting of powdered conidia with high viability (94.8%).

Effective Use of Alteplase for Occluded Tunneled Venous Catheter in Hemodialysis Patients

Despite their propensity for significant infectious and mechanical complications, tunneled central venous catheters (CVCs) have become a common means of vascular access in the world for patients requiring chronic hemodialysis for end-stage renal disease. The objective of this study was to explore if cryopreserved solutions of the thrombolytic agent alteplase could be used as an effective, safe, and economically reasonable alternative in hemodialysis patients with occluded tunneled CVC. Patients requiring chronic hemodialysis and presenting with occluded tunneled CVC received a sufficient volume of the alteplase solution to fill the occluded catheter. To make alteplase economically feasible, it was diluted to 1-mg/mL aliquots and they were stored at -20 degrees C until use. Eighty-one patients accounting for 179 attempted clearances were assessable for efficacy. One hundred forty-seven (82.1%) of the 179 catheter clearance attempts resulted in successful catheter clearance after one dose. Twenty-seven (15.1%) of all occluded CVCs were successful after two doses whereas five (2.8%) were not. No adverse events were reported. Cryopreserved 1-mg/mL aliquots of alteplase are safe and effective in the clearance of occluded CVC for hemodialysis patients.

Precipitação e aporte de nutrientes em diferentes estádios sucessionais de Floresta Atlântica, Pinheiral - RJ

Forest cover has importance within the context of the water balance of a particular site and may alter the mechanism of entry of water and nutrients to the soil surface. The aim of this study was to quantify the net precipitation, interception, addition of nutrients in throughfall and stem flow in a forest in different stages of regeneration of Mata Atlantica: early-stage secondary forest (ESSF), intermediary stage secondary forest (ISSF) and advanced stage secondary forest (AESF). The study was conducted in Pinheiral, Rio de Janeiro state. The data collection was performed during the period of April 2009 to March 2010. The values of incident precipitation, effective precipitation and interception were similar among the three stages evaluated. The AESF area showed higher values of Mg and P in the addition of nutrients from throughfall compared with other areas assessed. The pH of the precipitation incident did not differ among areas, but was higher than the pH of rainfall. The three areas evaluated showed no difference in the addition of nutrients to flow through the trunk. The AESF area showed a trend of higher levels of addition of nutrients from throughfall precipitation and runoff from stemflow.

Critérios para indicação de espécies prioritárias para a restauração da vegetação de cerrado

Knowing the attributes of the most suitable species to overcome the obstacles in different environmental conditions is an important tool for ecological restoration. To evaluate the comparative performance of native Cerrado species being cultivated at an arboretum (Assis State Forest, Assis, SP, Brazil), we categorized 106 species by the following attributes: average annual increment in height and crown diameter, survival rates, frequency of herbivory, frost susceptibility and seed dispersal syndrome. The score of each attribute may vary from 1 to 3, and the value of a species for restoration was generated from the sum of the scores for the different attributes converted to the scale of 0 to 100. Analyzing the species altogether, survival was 70%, the average annual increment was 30 cm in height and 21 cm in crown diameter. Only 8% of the species showed high susceptibility to frost and 17% high frequency of herbivory. Eighteen species had scores above 80, being the first Annona crassiflora, Cecropia pachystachya, Enterolobium gummiferum, Plathymenia reticulata e Protium heptaphyllum. In this group are the species that gather the highest number of favorable attributes for the restoration of Cerrado vegetation. We generated two separate lists of ten species of higher value, one for the cerrado sensu stricto and the other for cerradao the forest type of cerrado vegetation. We believe that using these species accelerates the recovery of vegetation structure and thus provide the restoration of ecological processes of ecosystems undergoing restoration. At the end of the list are species of low scores, which, if used, can lead to higher costs or delay in the recovery of structure and ecological processes of the ecosystem being restored.

Deus escreve certo por linhas tortas

If cinema is an essentially urban means of expression, the fruit of technique and industry, can a film narrator express in a film’s esthetics a caipira’s « Weltanschauung » (world vision or philosophy) ? We suggest, agreeing with Benjamin – who considers that narrative is the best expression of manual and traditional work’s time– that the story related by the film A proteção de Santo António constitutes a cinematographic narrative which can be classified as caipira. Tenderly called by the audiences Santo António e a vaca, this film was supported by a large part of the population for its making, which allowed to fill in the lack of technical and financial resources. Here, we defend the idea that the visible traces of this work in this particular film, turns it into a real filmic narrative and also into a sincere tribute to caipira culture.

Análise de notificação B em uma drogaria de Araraquara e avaliação do conhecimento dos prescritores quanto à legislação vigente

Uma das diretrizes da Portaria nº3916 do Ministério da Saúde (MS) é a Relação Nacional de Medicamentos Essenciais (RENAME). A prescrição de medicamentos dentro do Sistema Único de Saúde (SUS) deve ser feita utilizando medicamentos listados nessa relação. O medicamento genérico, criado e regulamentado pela Lei nº9787, é prioridade da Política Nacional de Medicamentos do MS. De acordo com esta lei, “as prescrições médicas e odontológicas de medicamentos, no âmbito do Sistema Único de Saúde – SUS adotarão obrigatoriamente a Denominação Comum Brasileira (DCB)”. A Portaria 344/98 MS, que regulamenta o controle dos medicamentos sujeitos a controle especial, determina os itens que devem estar presentes nas notificações. Neste trabalho, 1177 notificações retidas em uma drogaria de Araraquara durante o período de junho de 2008 a outubro de 2010 foram separadas e analisadas quanto: a) à utilização da DCB; b) quanto à utilização de medicamentos listados na RENAME; e c) quanto à adequação a Portaria 344/98 MS. Também foi avaliado o conhecimento dos prescritores quanto às leis vigentes através da aplicação de um questionário semiestruturado. Entre as 1177 notificações analisadas, 779 (66,18%) foram prescritas utilizando o nome comercial e 398 (33,82%) foram prescritas utilizando a DCB. Analisando as 399 notificações vindas do SUS, 188 (47,11%) adotaram os medicamentos da RENAME. Foram encontrados 319 problemas com as notificações de acordo com a Portaria 344/98 MS, os quais foram: 22 (1,86%) notificações com algum erro na identificação do emitente e/ou assinatura do prescritor; 3 (0,25%) notificações com algum erro na identificação do usuário; 294 (24,97%) notificações com preenchimento confuso nos itens como nome do medicamento ou substância, dosagem ou concentração, forma farmacêutica , quantidade e posologia; e 465 (39,50%)...

Turpilóquio em português e italiano: reflexões sobre marcas de uso de itens tabus em dicionários

In this paper, we tried to understand the place of taboo words and their importance in the language. We focused questions about the taboo and how words can be prohibited. We elected swear words as our object of research because these words have an important place in the lexicon of many speakers, and they are present in books and movies, as well as in the everyday speech. Therefore, we tried to show that they must be analyzed with attention and also free from prejudices. We found out that the use of bad words can be very different in the languages selected and they reflect thus the culture of the languages involved.
