BACKGROUND The process for obtaining monoclonal antibodies against a specific antigen is very laborious, involves sophisticated technologies and it is not available in most research laboratories. Considering that most cytokines remain partially conserved among species during evolution, the search for antibody cross-reactivity is an important strategy for(More)
BACKGROUND The main control strategy for visceral leishmaniasis in Brazil has been based on the elimination of seropositive dogs, although this is not widely accepted. In this context, the use of a long-lasting protective vaccine against canine visceral leishmaniasis (CVL) has been highly expected. The aim of this work was to determine the timeline kinetics(More)
Liver cirrhosis is responsible for a large number of deaths in our country (Angelo, 1977) as well as in many other parts of the world (Popper, 1975). In Portugal, during the year 1975, cirrhosis was the second most common cause of death among individuais between the ages of 25 and 44 and the third between the ages of 45 and 64 (Angelo, 1977). The mortality(More)
Vibration analysis does not cover all defects able to affect a rotating machine, including those that induce torque or instantaneous rotation speed fluctuations. Indeed the vibrational energy contributions of this type of defects such as a natural and gradual degradation of the gears are often weak. Therefore the appearance of these defects is very(More)
