In this study, the antimicrobial and antioxidant activities of Vicia villosa, Trifolium ochroleucum and Onobrychis altissima samples were investigated. For this purpose, plant extracts were tested against 3 fungus, 4 Gr(-) and 3 Gr(+) bacteria; additionally the glutathione (GSH) level and total phenolic content were measered spectrophtometrically and total antioxidant capacity (TAC) was done by...

We present evidence for the expression of three alpha-dystroglycan glycoforms in skeletal muscle cells, including two minor glycoforms marked by either patent or latent reactivity with the N-acetylgalactosamine-specific lectin Vicia villosa agglutinin. Both minor glycoforms co-isolated with beta-dystroglycan, but not with other dystrophin/utrophin-glycoprotein complex components, suggesting tha...

A soluble membrane component of type III pneumococcal polysaccharide-coupled spleen cells (S3-SCSM) induces S3-specific suppressor T cells (Ts) in mice. These Ts can be detected only if mice are pretreated with cyclophosphamide (Cy) or if cells adherent to the lectin Vicia villosa are removed from the spleen cell population prior to transfer. The V. villosa-adherent spleen cells from mice injec...

This work aimed to evaluate the influence of root exudates from cover crops: Raphanus sativus, Avena strigosa and Vicia villosa on germination development Zea mays, Amaranthus spinosus Ipomoea grandifolia. The tests performed were gas chromatography with mass spectrometry, rate, vigor, protrusion dry matter. Aliphatic amino acids (Alanine, Glycine, Isoleucine, Leucine, Proline, Serine, Threonin...

BACKGROUND Glomerular deposition of IgA1 is a common feature of Henoch-Schönlein purpura, and is indistinguishable from that seen in IgA nephropathy. Serum IgA1 is abnormally O-glycosylated in IgA nephropathy, and this may contribute to mesangial IgA1 deposition and the development of glomerular injury. This altered O-glycosylation of IgA1 can be detected by its increased binding to the lectin ...

Insect populations feeding on different plant species are under selection pressure to adapt to these differences. A study integrating elements of the ecology, behavior, and gene expression of aphids on different host plants has not yet been well-explored. The present study explores the relationship between host fitness and survival, feeding behavior, and salivary gland gene expression of a pea ...

Cyanamide had long been recognized as a synthetic compound but more recently has been found as a natural product from several leguminous plants. This compound's biosynthetic pathway, as yet unelaborated, has attracted attention because of its utility in many domains, such as agriculture, chemistry, and medicine. We noticed that the distribution of L-canavanine in the plant kingdom appeared to i...

Past work has shown that a subset of effector T cells with unique characteristics could abrogate haptenor antigen-induced tolerance, and the reconstitution of this immune response has been termed contrasuppression. We have studied contrasuppression in a model of oral tolerance (OT) in which adoptively transferred antigen-specific T contrasuppressor (Tcs) cells reverse OT and result in antibody ...
