human fascioliasis due to unknown species and animal fascioliasis caused by both or one of fasciola spp. are commonly seen in iran. to compare electrophoretic patterns of somatic and excretory-secretory antigens of f. hepatica and f. gigantica  by sodium dodecyl sulphate polyacrylamide gel electrophoresis (sds-page), the adult flukes were collected from infected slaughtered bovine livers. e/s a...

PURPOSE Investigate the activity of high and low molecular weight biomolecules present in the matrix of human calcium oxalate (CaOx) stones not only on the initial mineral phase formation of calcium and phosphate (CaP) but also on its growth and demineralization of the preformed mineral phase. MATERIALS AND METHODS Surgically removed renal stones were analyzed by Fourier Transform Infra Red (...

The temperature-sensitive hemagglutinin (Tsh) expressed by strains of avian pathogenic Escherichia (E.) coli (APEC) has both agglutinin and protease activities. Tsh is synthesized as a 140 kDa precursor protein, whose processing results in a 106 kDa passenger domain (Tsh(s)) and a 33 kDa β-domain (Tsh(β)). In this study, both recombinant Tsh (rTsh) and supernatants from APEC, which contain Tsh(...

CTP:phosphacholine cytidylyltransferase (EC 2.7.7.15) was purified from rat liver according to the method of Weinhold et al. (Weinhold, P. A., Rounsifer, M. E., and Feldman, D. A. (1986) J. Biol. Chem. 261, 5104-5110). Sodium dodecyl sulfate-polyacrylamide gel electrophoresis with or without beta-mercaptoethanol revealed a single major band of 42,000 daltons. This band corresponds to the 45-kDa...

Effect of peptides obtained from Phaseolus lunatus L. where biological properties such as antioxidant activity have been found. In addition to improve this beneficial effect, the microencapsulation could be a way protect against environment which they are exposed. Gums extracted plant seeds potential option Guazuma ulmifolia, and its gum exhibits promising coating materials in encapsulation. Tw...

Extracytoplasmic proteins were released from Serpulina (Treponema) hyodysenteriae (strain B204) by treatment of whole cells with a nonionic detergent (Tween 20). Centrifugation of the Tween 20-released proteins at 100,000 x g sedimented 10 major extracytoplasmic proteins with approximate molecular masses of 44, 43.5, 42, 39, 38, 34, 33.5, 33, 31, and 29 kDa. Treatment of the sedimented fraction...

Self-associated protein aggregates or cross-linked protein conjugates are, in general, more immunogenic than oligomeric or monomeric forms. In particular, the immunogenicity in mice of a recombinant malaria transmission blocking vaccine candidate, the ookinete specific Plasmodium falciparum 25 kDa protein (Pfs25), was increased more than 1000-fold when evaluated as a chemical cross-linked prote...

Tripeptidyl peptidase II (TPP II) is a large intracellular exopeptidase with an active site of the subtilisin type. Affinitypurified hen antibodies against human erythrocyte TPP II cross-reacted with fibronectin in an immunoblot analysis. Furthermore, antibodies against human fibronectin cross-reacted with TPP II. Antibodies against a 65 kDa cell-binding fragment of fibronectin specifically rea...
