| n-terminal region of the pb1-f2 protein is responsible for increased expression of influenza a viral protein pb1. | influenza a virus (iav) pb1-f2 protein is encoded by an alternative reading frame (+1) within the pb1 gene. pb1-f2 has been shown to contribute to the pathogenesis of influenza virus infection as well as to the secondary bacterial infection. more recently has been shown that pb1-f2 protein may regulate a viral rna (vrna) polymerase activity by the interaction with pb1 protein. we proved that pb1-f2 protein increased the level of expression of pb1 protein and vrna in the infected cells. moreover, ... | 2011 | 21434704 |

| hookworm disease: nutritional implications. | iron-deficiency anemia resulting from intestinal blood loss is the major consequence of hookworm infection. development of the anemia can be prevented, and it can be treated by administration of iron. hypoproteinemia, often associated with hookworm infection, may be the result of either protein malnutrition or increased intestinal loss of protein. it is unlikely that the worms cause diffuse morphologic or functional alterations of the intestine. fortification or supplementation with iron is a pr ... | 1982 | 6750748 |
