O objetivo deste trabalho foi verificar o efeito do ácido peracético e da colchicina na diferenciação de protocormos de Oncidium flexuosum. O ácido peracético foi testado previamente nas concentrações de 0, 3, 6 e 9 mL L-1, durante dez dias, para verificar a eficácia na esterilização do meio de cultura e os possíveis efeitos fitotóxicos nos protocormos. Após determinação da concentração, foram adicionados 6 mL L-1 de ácido peracético em meio MS com 0,05% de colchicina e DMSO 1%. Os protocormos foram mantidos em agitação pelos períodos: 0, 24, 48, 72, 96 e 120h. O experimento foi inteiramente casualizado com seis tratamentos, dez repetições e cinco protocormos por repetição. Após 30 dias, foi avaliada a sobrevivência dos protocormos e, após 180 dias, foram... |

ABSTRACT The quality of products derived from eggs depends on the quality of the raw material source and the industrial production. The contamination by fungi and bacteria can occur after exposure of the product in the retail market. The objective of this study was to evaluate the microbiological quality of 60 samples of derivated egg products and evaluate the effects of gamma radiation of cobalt-60, using the dose of 5 and 10 kGy, for decontamination of products collected in the retail market in the São Paulo city. The bacterial count was performed by the most probable number (MPN) and the fungal counts by serial dilution after plating surface. It was observed a decrease in the humidity and water activity (Aw) values of irradiated whole egg powder and... |

ABSTRACT Multipurpose use of bamboo in rural life makes it as poor man’s timber in Asian countries. Deforestation and industrialization leads to destruction of natural forest. To replenish, a rapid plantation of bamboo could be one of the possible solutions. Bamboo is propagated mainly by vegetative methods though it is not suitable for large scale plantation because of several limitations. Micropropagation is gaining importance for large scale propagation because of its capability in raising huge number of true to type propagules in a limited space in very short span of time. Like any other plant, the chief constraint of bamboo micropropagtion is in vitro contamination arises from several sources including explants. Most of the contaminants are reduced by... |

The use of biologically derived metal nanoparticles for various proposes is going to be an issue of considerable importance; thus, appropriate methods should be developed and tested for the biological synthesis and recovery of these nanoparticles from bacterial cells. In this research study, a strain of Klebsiella pneumoniae was tested for its ability to synthesize elemental selenium nanoparticles from selenium chloride. A broth of Klebsiella pneumoniae culture containing selenium nanoparticles was subjected to sterilization at 121ºC and 17 psi for 20 minutes. Released selenium nanoparticles ranged in size from 100 to 550 nm, with an average size of 245 nm. Our study also showed that no chemical changes occurred in selenium nanoparticles during the wet... |

It is estimated that electric drills (ED) have been used in orthopaedic surgeries for bone drilling for more than 50 years in Brazilian hospitals. It is an electric, thermosensitive equipment, not indicated for surgical use, which has not been previously evaluated regarding the sterilization efficacy, being suspect of infection risk. This study evaluated the efficacy of sterilization by ethylene oxide (EtO) of new drills that were intentionally contaminated with Bacillus atrophaeus spores. An experimental, laboratory, randomized applied research was developed, where 16 electric drills were analyzed, in addition to positive and negative controls. All the previously cleaned and sterilized equipment were submitted to contamination by spores. The experimental... |

Objective: To carry out a situational diagnosis of interactions among man, animal and environment, to test intervention and control model in dogs and cats and lo make local population aware in order to improve human and animal health. Material and Method: The project "Evaluation of risks to the heath and local intervention associated to living together with dogs and cats" was carried out in the area invaded in Jardim Paraná, District of Brasilândia, São PauLo city, Brazil, in 2003 by the Center of Zoonosis Control of the São Paulo Municipality.
