1. Como operacionalizar o atendimento de pacientes indígenas vítimas de acidentes ofídicos nas comunidades indígenas remotas da Amazônia Brasileira?
Os antivenenos são o único tratamento eficaz contra os efeitos de picadas de cobras venenosas e sua aplicação imediata é crucial para evitar complicações, sequelas e morte
. Desse modo, enquanto não ocorre a descentralização do tratamento antiveneno para unidades básicas de saúde indígena mais próximos das populacionais indígenas, os

2. O laser de baixa potência seria terapêutico para lesões causadas por acidentes ofídicos do gênero Bothrops?
Ainda não há evidências científicas em humanos, entretanto, em caráter experimental e de pesquisa, a laserterapia tem sido usada em lesões necróticas incapacitantes secundárias à picada por serpente na região amazônica, devido seu importante impacto em saúde pública pela retirada precoce do trabalhador na geração de renda. Assim, os benefí

3. Effects of therapeutic plasma exchange on liver function test and coagulation parameters in acute liver failure patients
ABSTRACT Background: Currently the treatment of choice for critical liver failure is liver transplantation. Liver failure is treated conservatively until a matching liver donor becomes available. The therapeutic plasma exchange (TPE) plays an important role as a bridge to transplantation by removing accumulated toxins from patient plasma, as well as restori

4. Dry fruit as source of fungal contaminants or functional compounds?
Abstract This study evaluated the role of dry fruits as a source of fungal contaminants or functional compounds. Dry apple, apricot, candied fruits, prune, and white and black raisin were evaluated regarding patulin and ergosterol content, centesimal composition, pH, acidity, pectin, and phenolic profile. The ergosterol was detected in 38% of the samples and

5. Performance of fungicides on the control of fusarium head blight (Triticum aestivum L.) and deoxynivalenol contamination in wheat grains
RESUMO A giberela é considerada uma doença de difícil controle, num cenário de dificuldades no seu controle químico e pela agressividade do patógeno em produzir toxinas. Diante disso, o objetivo do estudo foi verificar se fungicidas de distintos grupos químicos, isolados ou em mistura são eficazes no controle de giberela e na redução da contaminaç

6. Mycotoxin contamination of diets for beef cattle finishing in feedlot
ABSTRACT The objective of this survey was to identify what mycotoxins were present in ingredients used in diets offered to beef cattle in feedlots and their concentrations. The survey covered 30 Brazilian feedlots located in the five major beef-producing states. Samples of total mixed ration (TMR) and ingredients were collected and analyzed for mycotoxin usi

8. Antinociceptive effect of PnTx4(5-5), a peptide from Phoneutria nigriventer spider venom, in rat models and the involvement of glutamatergic system
ABSTRACT Background: The venom of Phoneutria nigriventer spider is a source of numerous bioactive substances, including some toxins active in insects. An example is PnTx4(5-5) that shows a high insecticidal activity and no apparent toxicity to mice, although it inhibited NMDA-evoked currents in rat hippocampal neurons. In this work the analgesic activity o

10. Jabuticaba (Plinia jaboticaba) skin extracts as inhibitors of phospholipases A2 and proteases
Abstract: The phenolic extracts of jabuticaba skin flour (JSF) were characterized by HPLC, and evaluated for their modulating action upon phospholipases A2 and proteases of snake venom, aiming at their possible use in the treatment of the various diseases associated with the action of venom toxins. Two types of extracts were prepared from JSF: aqueous and me

11. Spider venom peptides as potential drug candidates due to their anticancer and antinociceptive activities
Abstract Spider venoms are known to contain proteins and polypeptides that perform various functions including antimicrobial, neurotoxic, analgesic, cytotoxic, necrotic, and hemagglutinic activities. Currently, several classes of natural molecules from spider venoms are potential sources of chemotherapeutics against tumor cells. Some of the spider peptide to

12. Seleção de carvões ativados para adsorção de microcistinas
RESUMO A presença das cianobactérias é uma das grandes preocupações para o tratamento de água, uma vez que esses microrganismos podem ser produtores de metabólitos tóxicos, como as microcistinas (MCs), que não são efetivamente removidas no tratamento usualmente empregado de ciclo completo. Para a remoção dessas toxinas, pode-se, de forma compleme
