In addition to their role as a source of reduced carbon, sugars may directly or indirectly control a wide range of activities in plant cells, through transcriptional and post-translational regulation. This control has been studied in detail using Arabidopsis thaliana, where genetic analysis offers many possibilities. Much less is known about perennial woody(More)
Plasmodium vivax Duffy Binding Protein (Pv-DBP) is essential during merozoite invasion of reticulocytes. Reticulocyte binding region identification is important for understanding Pv-DBP reticulocyte recognition. Fifty 20 mer non-overlapping peptides, spanning Pv-DBP sequences, were tested in erythrocyte and reticulocyte binding assays. Ten HARBPs, mainly(More)

Immunogenic and protective peptide sequences are of prime importance in the search for an anti-malarial vaccine. The MSP-1 conserved and semi-conserved sequences have been shown to contain red blood cell (RBC) membrane high affinity binding peptides (HABP). HABP 1513 sequence ((42)GYSLFQKEKMVLNEGTSGTA(61)), from this protein's N-terminal, has been shown to(More)
The process of Mycobacterium tuberculosis infection of the macrophage implies a very little-known initial recognition and adherence step, important for mycobacterial survival; many proteins even remain like hypothetical. The Rv1510c gene, encoding a putatively conserved membrane protein, was investigated by analysing the M. tuberculosis genome sequence data(More)
Apical membrane antigen-1 is an integral Plasmodium falciparum malaria parasite membrane protein. High activity binding peptides (HABPs) to human red blood cells (RBCs) have been identified in this protein. One of them (peptide 4313), for which critical binding residues have already been defined, is conserved and nonimmunogenic. Its critical binding(More)
Plasmodium vivax, one of the four parasite species causing malaria in humans, is the most widespread throughout the world, leading to nearly 80 million cases per year, mainly in Latin-America and Asia. An open reading frame encoding the Plasmodium falciparum merozoite surface protein 8 P. vivax homologue has been identified in the present study by screening(More)
BACKGROUND Large-scale animal feeding operations compromise regional air quality in the rural US through emission of pollutants, such as ammonia gas. Exposure to airborne pollution from animal feeding operations may cause pediatric asthma exacerbations in surrounding communities. OBJECTIVES To describe spatial and temporal patterns in ambient ammonia(More)
The Ring-Infected Erythrocyte Surface Antigen (Pf155/RESA) sequence was chemically synthesized in fifty four 20-mer sequential peptides, covering the entire protein, each of which was tested in erythrocyte binding assays. Peptides 6671 and 6673, corresponding to residues 141-160 and 181-200, respectively, presented a high specific binding activity to(More)
Adhesion of mature asexual stage Plasmodium falciparum parasite-infected erythrocytes (iRBC) to the vascular endothelium is a critical event in the pathology of Plasmodium falciparum malaria. It has been suggested that the clag gene family is essential in cytoadherence to endothelial receptors. Primers used in PCR and RT-PCR assays allowed us to determine(More)
