Background: Human CD34 is a transmembrane glycoprotein which is expressed in human hematopoietic stem cells (HSCs) and the small- vessel endothelial cells of a variety of tissues. CD34 plays a critical role as a marker for diagnosis and classification of leukemia. Anti CD34 antibodies are used for isolation and purification of HSCs from bone marrow, peripheral blood and cord blood. Objective: ...

Background and Aims: Bovine leukaemia virus (BLV) is an oncogenic member of the genus Deltaretrovirus of the family Retroviridae. BLV is the causative agent of enzootic bovine leukaemia and infects cattle worldwide, imposing economic impact on the dairy cattle industry. The purpose of this study was to estimate the seroprevalence of BLV in cattle in some provinces of Iran. Materials and Methods...

AIM To detect and identify the causative agent or agents of the following clinical symptoms which were fever, lack of appetite, salivation, vesiculation, erosions of the buccal mucosa, nose, and feet. The signs vary from mild to severe. The mortality rate of the disease is high. The morbidity rate reaches up to 100%. Sheep also show bloody diarrhea and rapid respiration. Sheep flock resident in...

background: low dose theophylline may have some anti-inflammatory effects on copd patients. this study was conducted to determine the effect of oral low dose theophylline on serum crp level in patients with stable copd. methods: in this double blind randomized clinical trail study, 50 patients (25 in experimental and 25 in placebo group) were enrolled into the study by randomized blocking metho...

1. introduction the effect of blocking on iran’s precipitation in numeral way and long-term has not been done yet. however, in some researches based on weak indexes like one-dimension has been implied to iran that in studying many cases we observe lack of blocking event and or their continuation that has been for less than 5 days. this phenomenon in some cases occurs in our country directly and...

Malaria caused by Plasmodium falciparum is responsible for nearly 1 million deaths annually. Although much progress has been made in the recent past, the development of a safe, effective and affordable malaria vaccine has remained a challenge. A vaccine targeting sexual stages of the parasite will not only reduce malaria transmission by female Anopheles mosquitoes, but also reduce the spread of...

iran is a rather wide country, and, as a rule, the chrage per one call in s. t .d . (subscriber trunk dialing ) is required more compared with a local call , so, just after the opening of the std service widely in national telephone network, unconcerned use of the s. t. d. service has been caused on an incon- ceivable increase in telephone charge of th subscriber. this is a common problem for a...

Kundu and Bertino (VLDB 2008) recently introduced the idea of structural signatures for trees which support public redaction of subtrees (by third-party distributors) while pertaining the integrity of the remaining parts. An example is given by signed XML documents of which parts should be sanitized before being published by a distributor not holding the signing key. Kundu and Bertino also prov...

Background: CD90, a membrane-associated glycoprotein is a marker used to identify mesenchymal stem cells (MSCs). Recent studies have introduced CD90, which induces tumorigenic activity, as a cancer stem cell (CSC) marker in various malignancies. Blocking CD90 activity with anti-CD90 monoclonal antibodies enhanced anti-tumor effects. To date, highly specific antibody single-chain variable fragme...
