متن کاملEXPRESSION OF HEPATITIS B SURFACE ANTIGEN IN SACCHAROMYCES CEREVISIAE
The genome of HB V virus of serotype ayw cloned in pBR322 and expression shuttle vector p YES2 were used for construction of the HBsAg chimeric genes and their expression in Saccharomyces cerevisiae. Two recombinant plasmids were constructed. One of them contained the coding sequences for the major polypeptide of surface antigen. Another construct carried the major polypeptide with the pre-S2 a...
متن کاملNeuroendocrine control of ionic homeostasis in blood-sucking insects.
The pioneering work of Simon Maddrell established that the rapid postprandial diuresis of the haematophagous insect Rhodnius prolixus is controlled by a diuretic hormone and demonstrated the role of the Malpighian tubules in meeting the volumic, osmotic and ionic challenges posed by an enormous blood meal. A number of diuretic and antidiuretic hormones that control secretion of primary urine by...
متن کاملWhy do insects bite? A review of blood sucking behaviour.
Introduction There is considerable variation in the extent of the association between a blood sucking insect and its host. Blood sucking Diptera such as mosquitoes are temporary ectoparasites, only visiting the host for long enough to obtain a blood meal. Temporary ectoparasites such as tsetse flies, tabanids and mosquitoes tend to take relatively large blood meals, thus limiting the danger fro...
متن کاملSeroprevalence of Hepatitis A and Hepatitis B Viruses Among Blood Donors in North of Iran
Background and Objective: Hepatitis A virus (HAV) and hepatitis E virus (HEV) are both transmitted by the fecal-oral route and are known as leading causes of acute viral hepatitis in the world, especially in developing countries. There is a lack of updated data on HAV and HEV seroprevalence in the north of Iran. This study aimed to determine the seroprevalence of HAV and HEV among blood donors ...
