Lactadherin, a glycoprotein of the milk-fat globule membrane, contains tandem C domains with homology to discoidin-type lectins and to membrane-binding domains of blood-clotting factors V and VIII. We asked whether the structural homology confers the capacity to compete for the membrane-binding sites of factor VIII and factor V and to function as an anticoagulant. Our results indicate that lact...

the purpose of this survey was to evaluate natural occurrence and content of aflatoxin m1 (afm1) in dairy products marketed in urmia (iran). during september 2007, 40 samples of pasteurized milk, 40 samples of ultra high temperature treated (uht) milk, 40 samples of creamy cheese and 40 samples of iranian feta cheese were collected from different supermarkets in urmia city. afm1 contents were d...

background: aflatoxin m1 (afm1) as a carcinogenic and toxic compound has considerable significance from public health viewpoint. the aim of this study was to determine the level of afm1 in pasteurized and uht milk in west-azerbaijan province of iran. methods: a total of 360 commercial milk samples including 220 pasteurized milk and 140 ultra-high-temperature (uht) milk were purchased randomly f...

Latex-Ficus carica var. Kadota latex was collected from the green fruit of trees grown in the orchard of Mr. V. Ed Scott of Planada, California, as described (1). Subsequent storage and centrifugation have also been described (1). Reagents-Carnation instant nonfat dry milk was used for milk-clotting activity determinations. Barbital was obtained from Mallinckrodt Chemical Works, St. Louis, Miss...

The snake venom´s thrombin-like enzymes comprise a number of serine proteases, which are functionally and structurally related to thrombin. Purification and partial characterization of a thrombin-like enzyme from the venom of the Iranian snake, Agkistrodon halys, was the aim of this study. Purification was carried out by a combination of variety of chromatographic methods that included: gel...
