Proteomic analysis of honey bee brain upon ontogenetic and behavioral development.
Brain proteomes of nurses and foragers were compared by two-dimensional gel electrophoresis within pH range of 4-7 in order to find proteins related to such an ontogenetic and behavioral development in A. mellifera. Expand
Proteome analysis of brown spider venom: Identification of loxnecrogin isoforms in Loxosceles gaucho venom
The identification of dermonecrotic toxin isoforms in L. gaucho venom is an important step towards understanding the physiopathology of the envenomation, leading to improvements in the immunotherapy of loxoscelism. Expand
Triatoma infestans Apyrases Belong to the 5′-Nucleotidase Family*
The gene multiplication leading to the unusual salivary apyrase diversity in T. infestans could represent an important mechanism amplifying the enzyme expression during the insect evolution to hematophagy, in addition to an escape from the host immune response, thus enhancing acquisition of a meal by this triatomine vector of Chagas' disease.

Two β-xylanases from Aspergillus terreus: characterization and influence of phenolic compounds on xylanase activity.
Sugarcane bagasse was used as an inexpensive alternative carbon source for production of β-xylanases from Aspergillus terreus and showed that the xylanase activity was detected from the 6th day of cultivation period, indicating that xylan T1 is larger than Xyl T2. Expand
Proteomic analysis of the human pathogen Trypanosoma cruzi
Comparative proteome analysis of the cell‐cycle stages of T. cruzi revealed that few proteins included in the 2‐DE maps displayed significant differential expression among the three developmental forms of the parasite. Expand
Ontogenetic variation of metalloproteinases and plasma coagulant activity in venoms of wild Bothrops atrox specimens from Amazonian rain forest.
SDS-PAGE analysis of juvenile and adult venoms following autoproteolysis in pH 7.4 suggested that endogenous venom metalloproteinases can digest the 50kDa metaloproteinase, originating a new protein band of 27kDa. Expand
Proteomic Analysis Reveals That Iron Availability Alters the Metabolic Status of the Pathogenic Fungus Paracoccidioides brasiliensis
Comparing the two-dimensional gel protein profile of yeast cells during iron starvation to that of iron rich condition suggested a remodeling of P. brasiliensis metabolism by prioritizing iron independent pathways. Expand
The saliva proteome of the blood-feeding insect Triatoma infestans is rich in platelet-aggregation inhibitors
Abstract The saliva of the bloodsucking bug Triatoma infestans vector of Chagas disease contains an anti-hemostatic molecular cocktail that prevents coagulation, vasoconstriction and plateletExpand
Insight into the salivary transcriptome and proteome of Dipetalogaster maxima.
The redundancy of sequence identification of saliva-secreted proteins suggests that proteins are present in multiple isoforms or derive from gene duplications, including anticlotting, antiplatelet, and vasodilatory molecules. Expand
Identification, characterization and regulation studies of the aconitase of Paracoccidioides brasiliensis.
A protein species preferentially expressed in yeast cells with a molecular mass of 80 kDa and isoeletric point (pI) of 7.79 was isolated from the proteome of Paracoccidioides brasiliensis andExpand
