HPRS-103, the prototype of avian leukosis virus (ALV) subgroup J, was isolated in 1989 from meat-type chickens from commercial flocks where it induces myelocytic myeloid leukosis (ML). The HPRS-103 env gene differs considerably from other ALV subgroups but shows high identity (75-97%) to env-like sequences of the different members of the EAV family of endogenous avian retroviruses. Recently, we...
abstract governing was disorganized for years, when mongols attached to iran and it caused to clearing way for interference of mongols princes. dispatching of holaku to the west culminated in establishing iilkhanan government. holakus activities in destruction of abbaasis government and activities which shows his staying in iran, made force oulus juji to comparison against iilkhanis gover...
Mortality from myeloid leukosis was observed in commercial layers from 12 farms in northern China. Affected chickens were extremely thin and dehydrated, bleeding occurred in feather follicles and claws, combs were pale and anaemic, phalanges were swollen, and many yellowish-white tumours were seen on the visceral surface of the sternum. Focal tumour cells, with spherical eosinophilic granules i...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
In an attempt to determine the seroprevalence of avian leukosis virus (ALV) in exotic broiler chickens and Nigerian local chickens in Zaria, Nigeria, a total of 600 sera (300 from exotic broiler chickens and 300 from Nigerian local chickens), obtained from the live bird market in Zaria, Nigeria, were tested for ALV p27 antigen by the antigen capture enzyme linked immunosorbent assay (ac-ELISA) ...
Received: Revised: Accepted: Published online: December 28, 2014 July 11, 2015 October 05, 2015 January 01, 2016 Endogenous viral loci, designated as avian leukosis virus subgroup E (ALVE), have been found in the genome of commercial chickens. They sometimes modulate the host physiologic processes by changing the expression level of host promoters near an integration site. Therefore, the identi...
