Two saprophytic fungi (Mucor ramosissimus and Rhizopus sp.) were tested for their ability to induce phytoalexin production by seeds of frog-eye leaf spot and stem canker-resistant and -susceptible soybean (Glycine max L.) cultivars. Only M. ramosissimus was shown to elicit a response and qualitative differences in phytoalexin accumulation were found between(More)
Major histocompatibility complex class I chain-related gene A (MICA) was identified within the human leukocyte antigen (HLA) class I region and was located 46 kb centromeric from HLA-B locus. It functions as a ligand for human gammadelta T, CD8 T and natural killer (NK) cells by binding the NKG2D receptor. The aims of the present study were to determine the(More)
Dengue is the most prevalent arboviral disease in tropical and sub-tropical areas of the world. The incidence of infection is estimated to be 390 million cases and 25,000 deaths per year. Despite these numbers, neither a specific treatment nor a preventive vaccine is available to protect people living in areas of high risk. With the aim of seeking a(More)
Butia capitata is a palm tree endemic to the Cerrado biome of Brazil and has significant potential for ornamental and food uses. In this work, we characterized the structures of the seeds and seedlings of this species to identify anatomical aspects related to its pronounced dormancy and determine the processes involved in reserve mobilization. Intact seeds,(More)
Different series of N-alkylated diamines and their derivatives condensed to quinic acid were synthesized and tested for antibacterial properties against Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa, and Mycobacterium tuberculosis. The lipophilic chain and carbohydrate moiety modulate the antibacterial activity and the compounds(More)
MICA is a nonclassical polymorphic MHC molecule. We investigated MICA allelic frequencies and MICA-HLA-B-HLA-C haplotypes in Brazilian Amerindians to describe the polymorphism and to extract information about the evolution of MICA gene. Kaingang is the first population described to have a high frequency of MICA*020, found associated with(More)
