The aim of this study was to identify potential blood feeding sources of L. (L.) longipalpis specimens from populations in Northeastern Brazil, endemic areas of American Visceral Leishmaniasis (AVL) and its correlation with the transmission of L. (L.) i. chagasi. The ELISA technique was applied using bird, dog, goat, opossum, equine, feline, human, sheep, and rodent antisera to analyze 609 fema...
Boophilus microplus trypsin inhibitors (BmTIs) present in larvae were preliminarily characterized as active proteins, approximately 10-18 kDa, by SDS-PAGE. BmTIs showed trypsin inhibitory activity on reverse zymography containing gelatin (0.03%) and also inhibited others serine proteinases (human neutrophil elastase and human plasma kallikrein). Bos indicus, Nelore breed calves, previously sens...
In the present study, the bovine coronavirus (BCV) spike glycoprotein cleavage products (S1 and S2) were individually expressed in Spodoptera frugiperda (Sf9) insect cells, using a baculovirus expression system. The coding sequence of S1 and S2 gene fragments were amplified by RT-PCR and cloned into the baculovirus shuttle vector pBlueBac4.5/V5-His TOPO ® TA. The cloned fragments were inserted ...
Traditional geostatistical space-time geostatistics is not able to take account of the generally strongly non-linear dynamics of multivariate space-time processes. To this effect physico-chemical transport models are in general more suitable. However, as the latter do not fully master the complexity of the processes they attempt to describe, either because of simplifying hypotheses or because t...
In this paper, we present new attacks on the redactable signature scheme introduced by Kundu and Bertino at VLDB ’08. This extends the work done by Brzuska et al. at ACNS ’10 and Samelin et al. at ISPEC ’12. The attacks address unforgeability, transparency and privacy. Based on the ideas of Kundu and Bertino, we introduce a new provably secure construction. The corresponding security model is m...
Antiserum performance in a nephelometric system can be characterized by parameters derived from measuring reaction rates. The characterization process is derived from a series of dose-response curves (elicited nephelometric response vs antigen concentration) generated from various dilutions of the antiserum being tested. Antiserum titer can then be calculated by plotting the antigen concentrati...
The antral hormone gastrin regulates gastric acid secretion and growth of the gastric mucosa (1 ). As a result of the elaborate cellular maturation process of progastrin, the antral G cells release a mixture of different acidstimulatory gastrins and other precursor fragments to the circulation (2 ). This mixture comprises gastrin-71, -52, -34, -17, -14, and -6, all of which are carboxyamidated ...
Twenty tomato spotted wilt virus (TSWV) isolates were serologically compared in ELISA employing five different procedures using a rabbit polyclonal antiserum against nucleocapsid proteins (NuAbR) and mouse monoclonal antibodies (MAbs), two directed to nucleocapsid proteins (N1 and N2) and four directed to glycoproteins G1 to G4. All the antisera were raised against TSWV-CNPH1. The 20 isolates w...
